Description

Clock and watch

Technical Field

The present invention relates to timepieces, and in particular to improvements to a rotatable bezel (bezel).

Background

So-called diving watches and the like have a rotatable bezel in the case, the purpose of which is to facilitate the user to grasp the remaining time that can be spent in diving activities and the like.

The bezel is in a stopped state after rotating to a desired position, but there is a fear that the bezel is easily moved from the stopped position if it touches an obstacle or the like.

In order to restrict such an unexpected movement of the bezel, there has been proposed a rotation preventing (locking) mechanism which restricts rotation of the bezel except when the bezel is rotated and permits rotation of the bezel when the bezel is rotated (patent documents 1 and 2).

According to this technique, the lock member is engaged with the bezel to restrict the rotation of the bezel in a normal state in which the bezel is not operated, and, on the other hand, when the bezel is operated, the engagement of the lock member with the bezel can be released by pressing the button or the lock release button to rotate the bezel.

Disclosure of Invention

(problems to be solved by the invention)

However, the technique of patent document 1 is limited to allowing the bezel to rotate only while the button is held down, and therefore, when the bezel is rotated, the button needs to be held down all the time.

In other words, the operation of rotating the bezel must be performed while holding down the button, and the operation is difficult to perform by a single hand.

In addition, in a diving environment using a diving watch, it is difficult for the user to perform the above 2 operations simultaneously while wearing gloves.

Further, if the push button is not pressed by another device, the bezel may be accidentally rotated, and thus the bezel may be erroneously rotated.

On the other hand, in the technique of patent document 2, the bezel is allowed to rotate only during the period in which 2 lock release buttons are simultaneously pressed, so that the risk of erroneous release, which is feared in the technique of patent document 1 in which only one lock release button is provided, is reduced.

However, even when the bezel is rotated, it is necessary to constantly hold 2 lock release buttons, and therefore, it is difficult to operate the bezel with one hand, which is similar to the technique of patent document 1.

Furthermore, the above-mentioned problems are not limited to the above-mentioned diving watch, but also occur in watches having a rotatable bezel.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a timepiece in which a release operation for releasing a rotation-prevented state of a bezel and a rotation operation of the bezel can be easily performed, and erroneous release of the rotation-prevented state can be prevented or suppressed.

(means for solving the problems)

The timepiece of the invention uses the holding mechanism to hold the limiting member for preventing the rotation of the bezel at the limiting position for preventing the rotation of the bezel, and when the pressing operation force is simultaneously input to the 2 operation input parts of the holding mechanism, even if the input of the pressing operation force is not continued, the releasing mechanism of the holding mechanism can make the limiting member move from the limiting position to the releasing position, thereby the releasing operation for releasing the rotation preventing state of the bezel and the rotation operation of the bezel are not required to be simultaneously carried out, the two operations can be easily carried out, and only when the pressing operation force is not simultaneously input to the 2 operation input parts, the limiting member is held at the limiting position, thereby the error release of the rotation preventing state of the bezel can be prevented and even inhibited.

Namely, the timepiece of the present invention includes: a case member housing a timepiece movement; a bezel which is rotatably provided on the case member and has an engaged portion; a regulating member having an engaging portion that prevents rotation of the bezel in a state of being engaged with the engaged portion and allows rotation of the bezel in a state of not being engaged with the engaged portion, the regulating member being provided so as to be movable between a regulating position where the engaging portion is engaged with the engaged portion and a release position where the engaging portion is not engaged with the engaged portion; and a holding mechanism capable of switching between a holding state in which the regulating member is held at the regulating position and a non-holding state in which the regulating member is moved to the release position, the holding mechanism including: 2 operation input units for inputting pressing operation forces independent of each other; and a release mechanism that switches from the holding state to the non-holding state when a pressing operation force is simultaneously input to each of the 2 operation input portions, regardless of whether the input of the pressing operation force is continued.

According to the timepiece of the present invention, the operation of releasing the rotation-blocked state of the bezel and the operation of rotating the bezel can be easily performed, and erroneous release of the rotation-blocked state can be prevented or suppressed.

Detailed Description

Hereinafter, embodiments of the timepiece according to the present invention will be described with reference to the drawings.

(Structure)

A wristwatch 100 shown in fig. 1 (hereinafter referred to as "timepiece 100") is a diving wristwatch as one embodiment of the timepiece of the present invention.

This timepiece 100 includes a band 90 on a timepiece body 10 in a direction connecting 12 o 'clock and 6 o' clock of a dial plate, and is configured such that a wrist of a user passes in a direction connecting 9 o 'clock and 3 o' clock of the dial plate of the timepiece 100.

The watch body 10 is provided with a bezel 30 rotatable only in the counterclockwise direction by operation of a user's finger or the like on the upper surface of a case 20 (case member) accommodating the timepiece movement inside.

Here, the housing 20 may or may not include a back cover, not shown.

As shown in fig. 2, numerals and scales for indicating the remaining time and the like in accordance with the positional relationship with the minute hand of the timepiece main body 10 are displayed on the upper surface 31 of the bezel 30.

On the other hand, as shown in fig. 3A, teeth 33 (engaged portions) that repeat irregularities in the circumferential direction are formed on the lower surface 32 of the bezel 30.

The teeth 33 are formed such that convex portions 33a and concave portions 33B (see fig. 10A, 10B, and 10C) radially extend from the center of the bezel 30.

When the bezel 30 is to be rotated in the clockwise direction in a state where the bezel 30 is attached to the case 20, the teeth 33 are caught by the elastic claws 22a extending from the ring 22 shown in fig. 3B provided in the ring groove 21 of the case 20 to prevent the rotation of the bezel 30, and when the bezel 30 is to be rotated in the counterclockwise direction, the rotation is allowed by the elastic deformation of the elastic claws 22a, and a click feeling is given to the elastic claws 22a each time they pass over the convex portions 33a of the teeth 33, and a state where the bezel 30 is stopped is maintained in a state where the elastic claws 22a are fitted into the concave portions 33B between arbitrary adjacent 2 convex portions 33a, 33 a.

As shown in fig. 4, the teeth 33 are formed such that the convex portion 33a protrudes downward from the lower surface 32 of the bezel 30.

A restricting member 40 made of metal (stainless steel, titanium, or the like) or resin and a holding mechanism 50 are provided on the dial plate 9 side of the housing 20.

As shown in fig. 5, the regulating member 40 has 3 engaging teeth 42 (engaging portion, engaging convex portion) on the upper surface thereof, and the 3 engaging teeth 42 prevent the rotation of the bezel 30 in a state of meshing with (engaged with) the teeth 33 of the bezel 30 attached to the case 20, and allow the rotation of the bezel 30 in a state of not meshing with (disengaged from) the teeth 33.

The engaging teeth 42 engage with the concave portions 33b of the teeth of the bezel 30, and the concave portions between the engaging teeth 42 engage with the convex portions 33a of the teeth of the bezel 30, but the engagement may be only one.

The regulating member 40 is provided to be rotatable about a shaft 55 (shaft) inserted through the shaft hole 45 between a regulating position P1 at which the teeth 33 of the bezel 30 mesh with the engaging teeth 42 as shown in fig. 6A and 6B and a releasing position P2 at which the teeth 33 of the bezel 30 do not mesh with the engaging teeth 42 as shown in fig. 7A and 7B.

The restricting member 40 is provided with a rotation restricting portion 40 a. When the regulating member 40 is at the release position shown in fig. 7A and 7B, the rotation regulating portion 40a abuts against the housing 20 to regulate the range of rotation of the regulating member 40, so that the regulating member 40 is stopped at the predetermined rotational position shown in fig. 7A and 7B.

As shown in fig. 8A, a sleeve 56 is press-fitted to the outer peripheral surface of the shaft 55, and the sleeve 56 is formed in a cylindrical shape, and a slit 56a extending in the axial direction is formed in a part of the peripheral wall thereof, and has a C-shaped cross section (the cut portion of the C corresponds to the slit 56 a).

As shown in fig. 8B, the shaft hole 45 is formed with a small diameter portion 45B larger than the outer diameter of the shaft 55 but smaller than the outer diameter of the sleeve 56 into which the shaft 55 is press-fitted, and a large diameter portion 45a larger than the outer diameter of the sleeve 56 into which the shaft 55 is press-fitted.

Since the width of the slit 56a in the sleeve 56 is narrow before the shaft 55 is press-fitted, the outer diameter of the sleeve 56 is smaller than the outer diameter in the state where the shaft 55 is press-fitted and is larger than the small-diameter portion 45 b.

The diameter of the shaft support holes 51c, 51c formed in the legs 51a, 51b (engaging members) is smaller than the outer diameter of the sleeve 56 in which the shaft 55 is press-fitted.

The sleeve 56 is disposed in the large diameter portion 45a in advance before the shaft 55 is press-fitted, and in this state, the shaft 55 passes through the shaft holes 51c and 51c of the legs 51a and 51b and the shaft hole 45 of the regulating member 40, and the shaft 55 passes through the sleeve 56 while expanding the width of the slit 56a, while expanding the sleeve 56.

Therefore, since the sleeve 56 into which the shaft 55 is inserted has a larger outer diameter than the shaft support hole 51c formed in the leg 51a adjacent to the sleeve 56 and the small diameter portion 45b of the regulating member 40, the sleeve 56 is not removed from the large diameter portion 45a, and the shaft 55 is press-fitted into the sleeve 56, so that the shaft 55 and the sleeve 56 are integrated with each other, and the shaft 55 is prevented from being removed from the shaft hole 45.

A pitch P (fig. 9) between 2 adjacent engaging teeth 42 among the 3 engaging teeth 42 substantially coincides with a pitch of the outer peripheral edge of the teeth 33 of the bezel 30.

Tapered portions 42a, whose tips are tapered along the direction in which the 3 engaging teeth 42 are arranged, are formed at the tip of each engaging tooth 42.

Since the tapered portions 42a, 42a taper the tip end portions of the respective engaging teeth 42, the engaging teeth 42 easily enter the concave portions 33b of the teeth 33 in the process of approaching the teeth 33 from the state (fig. 10A) where the engaging teeth 42 are not engaged with the teeth 33 of the bezel 30 as shown in fig. 10.

In other words, even when the center of the engaging tooth 42 is displaced from the center of the concave portion 33B, as shown in fig. 10B and 10C, as the engaging tooth 42 enters the concave portion 33B, the tapered portion 42a comes into contact with the convex portion 33a, and the bezel 30 is rotated extremely slightly within the range of the looseness in the rotational direction by the load received by the convex portion 33a from the tapered portion 42a to absorb the displacement between the engaging tooth 42 and the concave portion 33B, so that the engaging tooth 42 is easily engaged with the tooth 33 of the bezel 30.

In addition, fig. 10A, 10B, and 10C only show one engaging tooth 42 that meshes with the tooth 33 in order to facilitate understanding of the function of the tapered portion 42a of the engaging tooth 42, and in the present embodiment, 3 engaging teeth 42 actually mesh with the tooth 33.

As shown in fig. 5, a tapered surface 41a inclined downward as it approaches a surface 48 facing the housing 20 is formed on a portion of the upper surface 41 of the regulating member 40 on the side closer to the housing 20, on which the engaging teeth 42 are formed.

The tapered surface 41a is formed in the vicinity of a position vertically above the shaft hole 45 through which the shaft 55 serving as the rotation center of the regulating member 40 passes, and as shown in fig. 7A and 7B, when the regulating member 40 rotates about the shaft 55, the tapered surface serves as "escape" for avoiding the upper surface 41 of the regulating member 40 from coming into contact with the lower surface 32 of the bezel 30.

In the present embodiment, 3 engaging teeth 42 are formed in order to sufficiently secure the engaging force with the teeth 33 of the bezel 30, but when the engaging force with the teeth 33 of the bezel 30 can be secured to some extent by selection of material, thickness, or the like, at least one engaging tooth 42 is sufficient.

For example, when the number of teeth 33 of the bezel 30 is small and the tooth-to-tooth interval is large (when the number of teeth is about 60), the engaging teeth 42 can be made thick, and therefore the strength and the engaging force of the engaging teeth 42 can be sufficiently ensured by one tooth.

Further, since the regulating member 40 of the present embodiment is formed of a metal material, the engaging force with the teeth 33 of the bezel 30 is sufficiently high by the high rigidity of the engaging teeth 42 and the synergistic effect of the 3 engaging teeth 42.

The holding mechanism 50 is a mechanism for switching between a holding state in which the regulating member 40 is held at the regulating position P1 and a non-holding state in which the regulating member 40 can be moved to the release position P2.

The holding mechanism 50 includes: a pair of leg portions 51a, 51b integrally formed with the case 20 and similar to the case ear 20a to which the band 90 is coupled; 2 buttons 52 and 52 (operation input units) fixed to the leg portions 51a and 51b, respectively; a spring lever 53 (elastic operation member) inserted into a spring lever hole 46 extending in parallel to the shaft hole 45 of the regulating member 40; and 2 pressing members 54 and 54 (restriction release urging members) each having a spring for urging (urging) the restriction member 40 in the direction of the release position P2 by an elastic force.

The 2 legs 51A and 51B are formed so as to sandwich the regulating member 40 in the direction along the connecting point 12 and the connecting point 6 of the dial, shaft support holes 51c and 51c for supporting the ends of the shaft 55 are formed in the surfaces 51t and 51t (hereinafter referred to as the facing surfaces 51t and 51 t) facing each other, as shown in fig. 11A and 11B, respectively, and the ends of the shaft 55 inserted into the shaft hole 45 of the regulating member 40 and protruding from the both end surfaces 47 and 47 of the regulating member 40 are supported by the corresponding shaft support holes 51c, respectively, whereby the regulating member 40 is supported so as to be rotatable about the shaft 55, as shown in fig. 6A, 6B, 7A, and 7B.

The legs 51a and 51b may be formed separately from the housing 20, and may be fixed to the housing 20 by screw fastening or the like after formation.

The legs 51a and 51b themselves may be configured as a part of the housing 20, not as a part of the holding mechanism 50.

As shown in fig. 12, the spring pin 53 inserted into the spring pin hole 46 of the regulating member 40 is provided with a spring 60 (see fig. 20) inside the cylindrical body, similarly to the spring pin for connecting the band 90 to the case band 20a, and the pair of end members 53a, 53a protruding from both ends of the cylinder are energized to a state of being extended outward of both ends of the cylinder by the elastic force of the spring 60 inside the body and are displaceable in the axial direction.

However, the end edges of the main body are formed so as to have respective inner diameters reduced, thereby preventing the end members 53a and 53a from coming off the cylindrical main body.

The spring rod 53 inserted into the spring rod hole 46 of the regulating member 40 is in a state in which part of the end members 53a and 53a protrude from both end surfaces of the regulating member 40.

As shown in fig. 11A, 11B, and 13, engagement holes 51d, 51d into which end members 53a, 53a protruding from both end surfaces 47, 47 of the regulating member 40 are fitted are formed in the leg portions 51A, 51B of the holding mechanism 50, respectively, and the engagement holes 51d, 51d are positioned on the extension line of the spring rod hole 46 of the regulating member 40 in the state where the regulating member 40 is at the regulating position P1.

Therefore, when the regulating member 40 is at the regulating position P1, the end members 53a, 53a of the spring rod 53 penetrating the regulating member 40 are fitted into the engagement holes 51d, 51d of the leg portions 51a, 51b, respectively, to hold the regulating member 40 at the regulating position P1.

The state where the restricting member 40 is held at the restricting position P1 is the holding state.

As shown in fig. 11A, 11B, 13, and 14, a tapered portion 51e is formed at an opening edge portion of the engagement hole 51d of the facing surfaces 51t and 51t of the legs 51A and 51B.

The engaging holes 51d and 51d are stepped holes having diameters that increase toward the outsides of the leg portions 51a and 51B (the direction of 12 o 'clock of the dial plate for the leg portion 51a and the direction of 6 o' clock of the dial plate for the leg portion 51B), and the buttons 52 and 52 are attached to the engaging holes 51d and 51d from the outsides of the leg portions 51a and 51B, respectively (fig. 11B, 13, and 14).

As shown in fig. 15, each of the buttons 52, 52 includes: the button housing portion 52 a; a button portion 52b and a pressing portion 52c that are integrally displaceable with respect to the button housing portion 52 a; and a spring 52d for energizing the button portion 52b and the pressing portion 52c toward a side of the button portion 52b that protrudes largely from the button housing portion 52a in a range in which the button portion 52b and the pressing portion 52c can be displaced relative to the button housing portion 52a (the position in the state shown in fig. 15).

The button case 52a is bonded to the engagement hole 51d of the leg 51a on the 12-dot side of the dial plate so that the button 52b protrudes toward the 12-dot side from the engagement hole 51d, and one button 52 is fixed to the leg 51 a.

Similarly, the button case 52a is bonded to the engagement hole 51d or the like so that the button portion 52b protrudes toward the 6 o 'clock side from the engagement hole 51d of the leg portion 51b on the 6 o' clock side of the dial, and the other button 52 is fixed to the leg portion 51 b.

The method of fixing the buttons 52, 52 to the engagement holes 51d, 51d is not limited to the above-described fixing with an adhesive, and may be fixing by press-fitting, or may be various fixing methods such as fixing with screws.

The button portions 52b, 52b of the buttons 52, 52 fixed to the engaging holes 51d, 51d protrude outward from the leg portions 51a, 51b (in the direction of 12 o 'clock of the button portion 52 fixed to the leg portion 51a, in the direction of 6 o' clock of the button portion 52 fixed to the leg portion 51 b) respectively, but are arranged inside the case 20, not protruding outward from the case 20, as a position along a straight line connecting 12 o 'clock of the dial (an end connecting the case 20a of the band (see fig. 1)) and an end of the case 100 on the 12 o' clock side (an end connecting the case 20a of the band) are arranged at positions along the straight line connecting 12 o 'clock and 6 o' clock of the dial (an end connecting the case 20a of the band).

Further, the button portion 52b protruding outward of the leg portions 51a and 51b with the button housing portions 52a fixed to the engaging holes 51d can be displaced in the input direction of the pressing force F by the input of the pressing force F in the direction toward the regulating member 40 (the direction of 6 o 'clock of the dial plate for the button portion 52b of the button 52 fixed to the leg portion 51a, and the direction of 12 o' clock of the dial plate for the button portion 52b of the button 52 fixed to the leg portion 51 b).

When the push button portion 52b is displaced in the input direction of the pressing operation force F, the pressing portion 52c presses the end member 53a of the spring lever 53 fitted in the engagement hole 51d in the axial direction thereof.

The end member 53a receives the pressing force F from the pressing portion 52c, and is displaced toward the main body side of the spring lever 53 against the elastic force of the spring provided inside the spring lever 53, and is disengaged from the engagement hole 51d as shown in fig. 14.

When the 2 end members 53a, 53a of the spring lever 53 are simultaneously disengaged from the engagement holes 51d, the restricting member 40 can be pivoted about the shaft 55 and displaced from the restricting position P1 to the release position P2.

The spring lever 53 and the engagement holes 51d and 51d constitute a release mechanism for switching the regulating member 40 from the holding state to the non-holding state.

The restricting member 40 is rotatable from the restricting position P1 to the non-holding state.

The pressing body 54 is provided with a spring therein, is expandable and contractible by the elastic force of the spring, and is accommodated in holes 49 and 49 formed in the surface 48 of the regulating member 40 facing the housing 20 shown in fig. 5.

When the pressing body 54 is accommodated in the holes 49, 49 of the regulating member 40, and partially protrudes from the surface 48 facing the housing 20, and the regulating member 40 is at the regulating position P1, the protruding portion comes into contact with the housing 20 and is contracted by the elastic force of the spring as shown in fig. 6A.

Therefore, the pressing body 54 applies an elastic force (pressing force) to the regulating member 40 to displace the regulating member 40 at the regulating position P1 to the release position P2.

(action)

Next, the operation of the timepiece 100 of the present embodiment will be explained.

First, as an initial state, the regulating member 40 is at the regulating position P1 shown in fig. 6A and 6B, and as shown in fig. 10C, the engaging teeth 42 of the regulating member 40 enter the concave portion 33B of the bezel 30, and the rotation of the bezel 30 is stopped by the engagement of the engaging teeth 42 with the teeth 33.

At this time, the pressing bodies 54, 54 are in the contracted state, and the restricting member 40 is pushed to rotate toward the release position P2, but the restricting member 40 is held at the restricting position P1 because the end pieces 53a, 53a of the spring lever 53 penetrating the spring lever hole 46 of the restricting member 40 are fitted into the engagement holes 51d, 51d of the leg portions 51a, 51b, respectively, as shown in fig. 13.

Here, if the button portions 52B, 52B of the 2 buttons 52, 52 are simultaneously input with the fingers of the user, the pressing operation forces F, F which are opposite to each other as shown in fig. 6B and 13, the button portions 52B, 52B are displaced in the input direction of the pressing operation force F, F as shown in fig. 14.

As a result, the pressing portions 52c and 52c formed integrally with the button portions 52b and 52b are also displaced in the input direction of the pressing operation force F, F, and the end member 53a of the spring lever 53 fitted into the engagement holes 51d and 51d of the leg portions 51a and 51b is pressed in the input direction of the pressing operation force F, F.

The end members 53a and 53a are pushed out from the engagement holes 51d and 51d as shown in fig. 14 by receiving the pressing force F, F against the elastic force of the spring built in the spring lever 53.

When the 2 end members 53a and 53a are simultaneously pushed out from the engagement holes 51d and 51d, the regulating member 40 is pivoted about the shaft 55 by the pressing force received from the pressing bodies 54 and 54, and moves to the release position P2 shown in fig. 7A and 7B.

At this time, the end members 53a and 53a are in contact with the facing surfaces 51t and 51t of the legs 51a and 51b and move integrally with the regulating member 40 while being placed on the facing surfaces 51t and 51 t.

When the regulating member 40 moves from the regulating position P1 to the release position P2, the engaging teeth 42 of the regulating member 40 disengage from the concave portion 33b of the bezel 30 and the engaging teeth 42 of the regulating member 40 disengage from the teeth 33 of the bezel 30, so that the bezel 30 can rotate.

Here, even if the finger that inputs the pressing force F, F to the button portions 52b, 52b of the buttons 52, 52 is removed from the button portions 52b, respectively, and the input of the pressing force F, F to the button portions 52b, 52b is canceled, the restriction member 40 rotates by the pressing force of the pressing bodies 54, and the end members 53a, 53a are in a state of being disengaged from the engagement holes 51d, and the state of being moved to the release position P2 is maintained, so that the non-holding state can be continued.

Therefore, in a state where the fingers are removed from the buttons 52, the operation of rotating the bezel 30 can be performed with the removed fingers or other fingers.

In the released state shown in fig. 7A and 7B, the rotation restricting portion 40a formed in the restricting member 40 abuts against the back surface of the housing 20, and restricts the range of rotation of the restricting member 40 so that the restricting member 40 stops at the rotational position shown in fig. 7A and 7B.

As described above, according to timepiece 100 of the present embodiment, when pressing operation force F, F is simultaneously input to each of 2 buttons 52, restriction member 40 can be switched from the held state to the non-held state even if input of pressing operation force F, F does not continue, and therefore, the operation of releasing the rotation-prevented state of bezel 30 and the operation of rotating bezel 30 can be performed separately, and both operations can be made easier than the conventional configuration in which the operation of releasing the rotation-prevented state of bezel 30 and the operation of rotating bezel 30 are performed simultaneously.

In the timepiece 100 of the present embodiment, even if the one end member 53a is disengaged from the engagement hole 51d, the other end member 53a remains fitted into the engagement hole 51d, and the regulating member 40 is held at the regulating position P1 in this state, and therefore, the regulating member 40 can be switched to the non-holding state only by simultaneously inputting the mutually independent pressing operation forces F, F to the 2 buttons 52 and simultaneously disengaging the 2 end members 53a, 53a from the engagement holes 51d, 51 d.

Therefore, according to the timepiece 100 of the present embodiment, even if one of the buttons 52 touches an obstacle or the like and the pressing force F is input to the button portion 52b, the regulating member 40 is maintained in the holding state, and therefore, it is possible to prevent or suppress the regulating member 40 from being erroneously moved to the release position P2 due to such an obstacle or the like.

The push button 52 for inputting the pressing force F is provided on the 9 o' clock side of the dial, and when the timepiece 100 is worn on the wrist of the left arm of the human body in a normal use state, the push button 52 is located on the upper arm side rather than the palm side with respect to the case 20.

In this case, the motion of touching the timepiece 100 with an obstacle from the upper arm side is extremely rare as the movement of the person, and if there is a motion of touching the timepiece 100 with an obstacle, this motion will also be a motion of touching the timepiece 100 with an obstacle from the palm side.

Therefore, according to the timepiece 100 of the embodiment in which the push button 52 is disposed on the upper arm side, the chance of the user accidentally coming into contact with an obstacle or the like and inputting the pressing force F to the push button 52 can be further reduced.

Further, since the 2 buttons 52, 52 are arranged separately above and below the 9 o' clock position of the dial, they are arranged along the width direction of the wrist worn by the timepiece 100, and even if the timepiece 100 touches an obstacle due to movement of the wrist, the probability that two positions are touched at the same time in the width direction of the wrist is extremely low, and thus, it is possible to further reduce the chance that the user inputs the pressing operation force F to the button 52 due to accidental contact with an obstacle or the like.

Further, since the positions of the button portions 52b and 52b of the buttons 52 and 52 fixed to the engaging holes 51d and 51d along the linear direction connecting the 12 point and the 6 point of the dial do not protrude outward from the case 20, when the wrist moves in the linear direction connecting the 12 point and the 6 point, even if the timepiece 100 touches an obstacle, the probability that the obstacle touches the end portion on the 12 point side or the end portion on the 6 point side of the case 20 is high, and the possibility that the button 52 at the position retracted inward of the case 20 will touch the end portion on the 12 point side or the end portion on the 6 point side is reduced as compared with the end portion on the 12 point side or the end portion on the 6 point side.

Note that the simultaneous input of the pressing force F, F to the 2 buttons 52 means that the period of time during which the 2 pressing forces F, F are input may be partially repeated.

Therefore, it is not necessary to make the timing of the start of input and the timing of the end of input of the 2 pressing forces F, F the same.

In the present embodiment, as shown in fig. 1, the buttons 52 and 52 are located on the side surfaces 20a 'and 20 a' of the ears 20a and 20a provided on the 12 o 'clock side and the 6 o' clock side, respectively. The side faces 20a ', 20 a' of the ears 20a, 20a extend along the pressing operation direction of the buttons 52, 52.

Therefore, when the user presses the watch 100 with the thumb and the index finger of the right hand from both sides of the buttons 52 and 52 in a state where the watch is worn near the wrist of the left arm of the user, the thumb and the index finger come into contact with the side surfaces 20a 'and 20 a' of the ears 20a and 20a (see fig. 1). Therefore, the side surfaces 20a ', 20 a' of the front ears 20a, 20a guide the movement of the thumb and the index finger in the button pressing direction, so that the buttons 52, 52 can be easily and reliably pressed from both sides even when, for example, diving gloves are worn on the hand on the operation side, and the holding state of the regulating member 40 can be released.

Of course, the buttons 52 and 52 may be separated from the side surfaces 20a 'and 20 a' of the ears 20a and 20a without being used as a guide for movement in the button pressing direction.

In the present embodiment, as shown in fig. 5, 6A, and 7A, the outer corner 40c of the bottom surface 40b of the regulating member 40 is obliquely cut so as to be a slope.

Therefore, when the timepiece 100 is worn near the wrist of the arm of the user, for example, even if the wrist is bent or the outside corner 40c side of the bottom surface 40b of the regulating member 40 is brought close to the wrist of the arm, the outside corner 40c is inclined rather than a right angle, and therefore, the timepiece does not get stuck or caught in the arm.

In the timepiece 100 of the present embodiment, the end piece 53a of the spring lever 53 fitted in the engagement hole 51d is disengaged from the engagement hole 51d by the pressing force F input to the push button 52, and the end piece 53a is engaged with the facing surface 51t of each leg 51a, 51b by the movement of the regulating member 40 in the direction toward the release position P2.

Here, if the end piece 53a of the spring rod 53 corresponding to one of the push buttons 52 is disengaged from the engagement hole 51d only when the push operation force F is applied to the one push button 52 (in a state where the end piece 53a of the spring rod 53 corresponding to the other push button 52 is fitted in the engagement hole 51 d), if the spring rod 53 is inclined with respect to the spring rod hole 46 due to play or the like between the outer diameter of the spring rod 53 and the inner diameter of the spring rod hole 46, there is a possibility that only the state where the one end piece 53a is engaged with the opposing surface 51t is maintained.

In this case, if the pressing force F is input only to the other button 52 after the input of the pressing force F to the one button 52 is lost, the end piece 53a of the spring lever 53 on the side corresponding to the other button 52 is also disengaged from the engagement hole 51d, and therefore, even if the input of the pressing force F to the one button 52 is simultaneously lost, the regulating member 40 may be switched from the holding state to the non-holding state.

However, in the timepiece 100 of the present embodiment, as shown in fig. 11A, 11B, 13, and 14, since the tapered portion 51e is formed at the opening edge of the engagement hole 51d of the surface of each leg portion 51A and 51B facing the regulating member 40, even if only one end member 53a attempts to fit on the facing surface 51t due to inclination of the spring lever 53 or the like, the tapered portion 51e that guides the end member 53a to the engagement hole 51d is formed at the portion where the spring lever 53 is fitted, as shown in fig. 16, the end member 53a fits on the tapered portion 51e, and the end member 53a returns to the state of being fitted again to the engagement hole 51d due to inclination of the tapered portion 51 e.

Therefore, it is possible to reliably suppress the restriction member 40 from being switched to the non-holding state due to the alternate input of the pressing operation force F to the 2 buttons 52.

When the bezel 30, which has been brought into the rotatable state by moving the regulating member 40 to the release position P2, is to be returned to the original rotation-prevented state (the holding state of the regulating member 40), the regulating member 40 moved to the release position P2 is pressed (pressed back by an input operation force) with a finger or the like and moved to the regulating position P1 against the spring force of the springs of the pressing bodies 54, 54.

Thus, if the regulating member 40 returns to the regulating position P1, as shown in fig. 10C, the engaging teeth 42 of the regulating member 40 engage with the teeth 33 of the bezel 30 to prevent the rotation of the bezel 30.

Further, at the time when the pressing force F applied to the button portions 52b, 52b input when the regulating member 40 is switched to the non-holding state is removed, the pressing portions 52c, 52c of the buttons 52, 52 are returned to the state retracted more inward than the facing surfaces 51t, 51t of the leg portions 51a, 51b by the elastic force of the spring 52d (fig. 15), and therefore, when the regulating member 40 is returned to the regulating position P1, as shown in fig. 13, the two end pieces 53a, 53a of the spring lever 53 penetrating the spring lever hole 46 of the regulating member 40 are fitted into the engaging holes 51d, 51d of the two leg portions 51a, 51b, respectively, and the regulating member 40 is held at the regulating position P1.

In the timepiece 100 of the present embodiment, when the regulating member 40 is at the regulating position P1, the outer peripheral surface 44 of the regulating member 40 is formed in a contour shape smoothly continuous with the outer peripheral surfaces 51s, 51s of the 2 legs 51a, 51B without a step difference as shown in fig. 6B, and when the regulating member 40 is at the release position P2, the outer peripheral surface 44 of the regulating member 40 protrudes outward from the outer peripheral surfaces 51s, 51s of the 2 legs 51a, 51B as shown in fig. 7B.

Therefore, when the regulating member 40 is at the regulating position P1, the outer peripheral surface 44 of the regulating member 40 does not protrude discontinuously from the outer peripheral surfaces 51s and 51s of the leg portions 51a and 51b, and it is possible to avoid a situation in which, if there is a discontinuity, an obstacle is caught in the discontinuity and the regulating member 40 or the leg portions 51a and 51b are damaged.

On the other hand, when the regulating member 40 at the release position P2 is returned to the regulating position P1, the outer peripheral surface 44 of the regulating member 40 protrudes outward beyond the outer peripheral surfaces 51s, 51s of the leg portions 51a, 51b, so that the protruding outer peripheral surface 44 can be pressed by a finger or the like in the direction of the regulating position P1, and the user can easily visually recognize that the regulating member 40 is at the release position P2, whereby the return to the regulating position P1 can be promoted.

In the timepiece 100 of the present embodiment, a triangular mark 43 (released state display portion: fig. 5) is shown on the upper surface 41 of the regulating member 40, and as shown in fig. 17A, when the regulating member 40 is at the regulating position P1, the mark 43 is positioned below the bezel 30 and hidden from view, whereas as shown in fig. 17B, when the regulating member 40 is at the releasing position P2, the mark 43 is exposed outside the bezel 30 and visible from the outside.

Therefore, even when it is difficult to visually recognize that the regulating member 40 is at the release position P2 due to the projection of the outer peripheral surface 44 of the regulating member 40 as described above, the user can easily recognize that: that is, the restricting member 40 is at the release position P2 when the marker 43 is visible, and the restricting member 40 is at the restricting position P1 when the marker 43 is invisible.

The mark 43 is not limited to a triangular mark, and other marks having other shapes such as an arrow mark may be used.

Further, the mark 43 is not set to be entirely hidden or entirely visible, but may be set to: when the mark is at the regulation position P1 shown in fig. 17A, only a part of the mark 43 (for example, when the mark 43 is a triangular mark, from the tip to the center of the triangle as the mark) is hidden, and when the mark is at the release position P2 shown in fig. 17B, a part of the hidden mark (from the tip to the center of the triangle as the mark) appears and is visible.

In addition, in the timepiece 100 according to the present embodiment, since the pressing body 54 is energized in the direction of displacing the regulating member 40 toward the release position P2, in order to return the regulating member 40 temporarily moved to the release position P2 to the regulating position P1, it is necessary to apply a pressing force in the direction of the regulating position P1 against the elastic force generated by the pressing body 54, and it is possible to prevent the regulating member 40 from unexpectedly returning to the regulating position P1 due to its own weight.

In the timepiece 100 according to the present embodiment, the push body 54 also constitutes a part of the holding mechanism and the release mechanism in the timepiece according to the present invention, and even in a timepiece not having the push body 54, the regulating member 40 can be switched from the held state to the non-held state regardless of whether the input of the push operation force F to the push button 52 is continued.

The pressing body 54 may be provided not on the restricting member 40 side but on the housing 20 side.

However, in the configuration in which the pressing body 54 is provided on the restricting member 40 side, when the pressing body 54 is broken, the pressing body 54 to which the restricting member 40 is fixed can be replaced with a new one as a single replacement member, and the repair can be easily performed.

If the pressing body 54 is provided on the housing 20 side, the pressing body 54 needs to be removed from the housing 20 (the pressing body 54 is previously configured to be removable) or replaced with respect to the housing 20.

In the timepiece 100 of the present embodiment, the 2 push buttons 52, 52 are provided so that the direction of the input push operation force F, F is orthogonal to the direction in which the regulating member 40 can move between the regulating position P1 and the release position P2, and therefore the regulating member 40 can be firmly held at the regulating position P1 when the push operation force F is not input.

The timepiece 100 of the present embodiment has a structure in which the teeth 33 as the engaged portions are formed on the lower surface 32 of the bezel 30, but the engaged portions of the timepiece of the present invention may be formed on the outer periphery of the bezel.

That is, for example, as shown in fig. 18, the following manner may be applied: a tooth 33 having a concavo-convex shape as an engaged portion is formed on the outer periphery (not the outermost surface) of the bezel 30, the engaging tooth 42 of the regulating member 40 located at the regulating position P1 is engaged with the tooth 33 to prevent the rotation of the bezel 30, and the engaging tooth 42 of the regulating member 40 located at the releasing position P2 is disengaged from the tooth 33 to allow the rotation of the bezel 30.

In addition, in the timepiece 100 of the present embodiment, the conventional teeth 33 formed on the bezel 30 are used as the engaged portions, but the timepiece of the present invention is not limited to the structure in which the conventional teeth formed on the bezel are used as the engaged portions, and for example, even if the teeth 33 are formed on the lower surface 32 as in the present embodiment, the same number of concave-convex shapes as the teeth 33 may be newly formed on the outer peripheral surface of the bezel, and the concave-convex shapes may be used as the engaged portions to be engaged with the engaging portions of the regulating member.

In the timepiece 100 of the present embodiment, the leg portions 51a and 51b are formed separately from the case 20, and the leg portions 51a and 51b formed separately are fixed to the case 20 by screwing or the like, and this structure has an effect of facilitating adjustment of the engagement between the engaging teeth 42 of the regulating member 40 at the regulating position P1 and the teeth 33 of the bezel 30.

The timepiece 100 according to the present embodiment employs the movement of the regulating member 40 caused by the rotation between the regulating position P1 and the release position P2, but the timepiece according to the present invention is not limited to the movement caused by the rotation, and may employ a parallel movement, a combination of a parallel movement and a rotation, or the like.

In the timepiece 100 of the present embodiment, as shown in fig. 19 and 20, annular unlocking marks 61, 61 may be formed on the outer peripheral surfaces of both the push buttons 52, 52.

As shown in fig. 19 and 20, when the push buttons 52 and 52 are not pushed in (when the regulating member 40 is in the holding state), the lock release marks 61 and 61 are at positions exposed to the outside of the leg portions 51a and 51 b. As shown in fig. 21 and 22, when the buttons 52 and 52 are pushed to predetermined positions (when the regulating member 40 is in the released state), the lock release marks 61 and 61 are positioned so as to be hidden by the leg portions 51a and 51 b.

By providing the lock release marks 61, 61 on the outer peripheral surfaces of the buttons 52, 52 in this way, when the user pushes the operation buttons 52, the user can easily grasp that the restriction member 40 is released by pushing the operation buttons to a position where the lock release marks 61, 61 are hidden from view. For the user to visually recognize the lock release marks 61, a conspicuous color such as red or yellow is preferable.

Fig. 23A, 23B, 24A, and 24B show another embodiment of the timepiece according to the present invention to which the regulating member 40' is configured to move in parallel between the regulating position P1 (fig. 23A and 23B) and the release position P2 (fig. 24A and 24B).

The regulating member 40 'of the timepiece 100' of this embodiment is configured to support the regulating member 40 'to the case 20 so that the regulating member 40' moves in parallel between the regulating position P1 and the release position P2 by replacing the shaft 55 shown in fig. 2 with 2 guide rods 55 ', 55'.

The 2 guide rods 55 ', 55 ' are arranged in parallel with each other, and are inserted into the guide holes 45 ', 45 ' formed in the regulating member 40 ' from the outer peripheral surface 44 side of the regulating member 40 ' toward the housing 20, and the regulating member 40 ' is fixedly supported by the housing 20 by screwing the male screw formed at the insertion tip side into the female screw formed in the housing 20.

Further, around the guide lever 55 ', a spring 54 ' is disposed which is sandwiched between the case 20 and the regulating member 40 ', and this spring 54 ' applies a pressing force in a direction to displace the regulating member 40 ' at the regulating position P1 to the release position P2, similarly to the pressing body 54 in the timepiece 100 of the embodiment shown in fig. 2.

The structure other than the structure of the support regulating member 40' is the same as the timepiece 100 according to the embodiment shown in fig. 2 unless otherwise specified.

According to the timepiece 100 'of this embodiment, the 2 end members 53A, 53A of the spring lever 53 are simultaneously pushed out from the engagement holes 51d, 51d by the pressing force F, F simultaneously input to the buttons 52, and the regulating member 40' at the regulating position P1 shown in fig. 23A, 23B is moved in parallel along the guide levers 55 ', 55' to the release position P2 shown in fig. 24A, 24B by the pressing force received from the springs 54 ', 54'.

If the regulating member 40' moves from the regulating position P1 to the releasing position P2, the engaging teeth 42 of the regulating member 40 disengage from the concave portion 33b of the bezel 30 and the engagement of the engaging teeth 42 of the regulating member 40 with the teeth 33 of the bezel 30 is released, so that the bezel 30 can rotate.

When the regulating member 40 'moves to the release position P2 and the bezel 30 in the rotatable state is to be returned to the original rotation-prevented state, the regulating member 40' moved to the release position P2 is pressed to the regulating position P1 against the elastic force of the springs 54 ', 54' with a finger or the like.

Thus, if the regulating member 40 'returns to the regulating position P1, as shown in fig. 23A and 23B, the engaging teeth 42 of the regulating member 40' engage with the teeth 33 of the bezel 30, and the rotation of the bezel 30 is stopped.

Further, according to timepiece 100 'of this embodiment, when pressing operation force F, F is simultaneously input to each of 2 buttons 52, restriction member 40' can be switched from the holding state to the non-holding state even if the input of pressing operation force F, F does not continue, and therefore, the operation of releasing the rotation-prevented state of bezel 30 and the operation of rotating bezel 30 can be performed separately, and both operations can be made easier than the conventional configuration in which the operation of releasing the rotation-prevented state of bezel 30 and the operation of rotating bezel 30 are performed simultaneously.

In addition to the above-described effects, the timepiece 100' of the present embodiment exhibits other effects similar to those exhibited by the timepiece 100 shown in fig. 2, and the effects are similar to those exhibited by the timepiece 100, and therefore, the description thereof is omitted.

However, in the timepiece 100 ' of this embodiment, if there is not a certain degree of clearance between the facing surfaces 51t, 51t of the leg portions 51a, 51b and the both end surfaces 47, 47 of the regulating member 40 ' and between the surfaces of the guide rods 55 ', 55 ' and the surfaces of the guide holes 45 ', the regulating member 40 ' cannot smoothly move from the regulating position P1 to the release position P2 due to friction between the both end surfaces 47, 47 of the regulating member 40 ' and the facing surfaces 51t, 51t and friction between the surfaces of the guide rods 55 ', 55 ' and the surfaces of the guide holes 45 ', and if the clearance is excessively large, the regulating member 40 ' may tilt and only one end piece 53a may easily come off the engaging hole 51 d.

In contrast, in the timepiece 100 shown in fig. 2 in which the regulating member 40 rotates about the shaft 55, the rotation of the regulating member 40 is guided only by the shaft 55, and the inclination of the regulating member 40 only needs to take into consideration the clearance of the shaft hole 45 of the regulating member 40 with respect to the shaft 55, so that only one end piece 53a is unlikely to come out of the engagement hole 51 d.

In the timepiece 100 ' according to the embodiment shown in fig. 23A, 23B, 24A, and 24B, the bottom plate 26 that supports the regulating member 40 ' from below in an auxiliary manner is formed below the regulating member 40 ', and the regulating member 40 ' is supported by the 2 guide rods 55 ', so that the bottom plate 26 may be removed.

In addition, since the timepiece 100 shown in fig. 1 is a diving watch type, it is often used in seawater or the like, and when sand or the like adheres to the outer peripheral side or the back side of the bezel 30, for example, tap water flowing out from a faucet is sprayed around the bezel 30 to wash away the adhering sand or the like.

At this time, since the gap between the surface 48 of the regulating member 40 and the case 20 is small, sand entering the gap between the surface 48 of the regulating member 40 and the case 20 or the gap between the teeth 33 of the bezel 30 is not easily washed away by tap water.

Therefore, in the timepiece 100, as shown in fig. 25 and 26, the case 20 side surface 48 of the regulating member 40 is formed with a cut surface 40d of a predetermined width inclined so as to have a deeper depth of cut from the vicinity of the central portion of the surface 48 toward the bottom surface 40b side, and the cut surface 40d forms an opening for allowing water to flow between the case 20 and the bottom surface 40b side of the surface 48 of the regulating member 40.

The notch surface 40d is located between 2 holes 49, 49 formed in the surface 48, and the upper portion of the notch surface 40d is located below the holes 49, 49. The shape, size, and the like of the notch surface 40d may be shapes and sizes other than those shown in fig. 27 as long as the range does not interfere with the turning operation associated with the release of the holding state of the regulating member 40.

When sand or the like entering the gap between the surface 48 of the regulating member 40 and the case 20 or the gap between the teeth 33 of the bezel 30 is to be washed away by tap water, the regulating member 40 is rotated by releasing the holding state of the regulating member 40 as shown in fig. 27. If tap water flows into the notch surface 40d from the opening on the bottom surface 40b side of the notch surface 40d (the arrow a in fig. 27 indicates the direction of the flow of tap water), tap water flows from the notch surface 40d through the gap between the surface 48 of the regulating member 40 and the case 20, and is discharged to the outside through the gap between the lower surface 32 of the bezel 30 and the regulating member 40.

At this time, tap water also flows through the gaps between the teeth 33 of the bezel 30, and therefore, sand or the like that has entered the gap between the surface 48 of the regulating member 40 and the case 20 or the gap between the teeth 33 of the bezel 30 is also discharged.

In addition, tap water may be flowed from the bezel 30 side, as opposed to the bottom surface 40b side of the notch surface 40 d. In this case, the tap water flowing in through the gap between the lower surface 32 of the bezel 30 and the regulating member 40 passes through the gap between the surface 48 of the regulating member 40 and the case 20, and is discharged to the outside through the opening on the bottom surface 40b side of the cutout surface 40 d. At this time, tap water also flows through the gaps between the teeth 33 of the bezel 30, and therefore, sand or the like that has entered the gaps between the surface 48 of the member 40 and the case 20 or the gaps between the teeth 33 of the bezel 30 is also discharged.

As shown in the timepiece 100 ' shown in fig. 23A and 24A, when the regulating member 40 ' is moved in a direction away from the case 20 when the holding state is released, a hole 26a for passing water may be formed in the bottom plate 26 (fig. 23A and 24A) that assists in supporting the regulating member 40 '.

In this case, tap water may be caused to flow to the side of the gap between the surface 48 of the regulating member 40 'and the case 20 through the hole 26a in the same manner as described above, or tap water that has flowed into the gap between the surface 48 of the regulating member 40' and the case 20 from the gap between the lower surface 32 of the bezel 30 and the regulating member 40 may be discharged to the outside through the hole 26 a.

As shown in fig. 26, the bottom surface 40b of the regulating member 40 is located higher than the surface of the back cover 62. Further, as shown in fig. 27, even if the holding state of the regulating member 40 is released and the regulating member 40 is rotated, the bottom surface 40b of the regulating member 40 is still at a position higher than the surface of the back cover 62.

Therefore, in a situation where the timepiece 100 is worn near the wrist of the user, the bottom surface 40b of the regulating member 40 is separated from the vicinity of the wrist even if the back cover 62 is in contact with the vicinity of the wrist, and therefore, when the operation buttons 52, 52 are pressed simultaneously, the bottom surface 40b of the regulating member 40 is reliably turned without being in contact with the vicinity of the wrist, and the holding state of the regulating member 40 can be released.

(description of an example of tubes formed as separate bodies)

Fig. 28A and 28B show a modification of the present embodiment in which engagement holes 51d 'and 51 d' are formed in tubes 51g 'and 51 g' that are separate from the leg portions 51a 'and 51B'.

The timepiece 100 "of the embodiment of the above-described modification forms the tube insertion hole 51f ' in the leg portion 51a ', and the tube 51g ' is inserted therein.

The leg 51b 'is formed with a tube insertion hole 51 f' as with the leg 51a ', and a tube 51 g' is inserted therein, which is not shown.

The tube 51 g' doubles as the button housing portion 52a in fig. 15.

The tube 51g 'is attached to the leg portions 51 a', 51b 'after the button portion 52 b' of the button 52 'is attached to the tube 51 g'.

(hard material)

The tubes 51g ', 51 g' are formed of a harder material (e.g., titanium alloy) than the leg portions 51a ', 51 b'.

For example, the leg portions 51a ', 51b ' integral with the housing 20 ' are made of titanium, and the tubes 51g ', 51g ' are made of a titanium alloy.

Further, engaging holes 51d ', 51 d' and tapered portions 51e ', 51 e' are formed in the tubes 51g ', 51 g'.

(processing of taper portion)

In the timepiece 100 shown in fig. 1 to 18, the spring lever 53 is disposed between the leg portions 51a, 51b, and therefore, the tapered portion 51e needs to be formed on the facing surfaces 51t, 51t of the leg portions 51a, 51 b.

Since the length of the drill for forming the tapered portion 51e in the leg portion 51a is longer than the length between the facing surfaces 51t, 51t of the leg portions 51a, 51b, the tapered portion 51e is formed by bringing only the tip portion of the drill into contact with the portion to be formed with the tapered portion 51e from the outside between the facing surfaces 51t, 51t of the leg portions 51a, 51 b.

In this case, the drill has to be brought into contact with the facing surface 51t in a state where the engagement hole 51d of the leg 51a is inclined with respect to the axial direction of the engagement hole 51d from the side portion side in the 9 o' clock direction of the leg 51 b.

Since the drill for machining the tapered portion 51e is inclined with respect to the axial direction of the engagement hole 51d, it may be difficult to machine the tapered portion 51e with high accuracy when a drill for precision machining is used that is parallel to or perpendicular to the reference axis of the object, for example.

In contrast, in the timepiece 100 ″ shown in fig. 28A and 28B, since the engaging hole 51d ' and the tapered portion 51e ' are formed in the tube 51g ' that is separate from the leg portion 51a ', the tapered portion 51e ' can be processed in the tube 51g ' before engaging with the engaging hole 51d '.

That is, the tapered portion 51e 'can be machined with high precision by using an automatic lathe to machine the tapered portion 51 e' by bringing a cutting tool into contact with the tapered portion.

(surface quality of taper part)

Further, in the timepiece 100 described above, since the length between the facing surfaces 51t, 51t of the leg portions 51a, 51b is short, it is difficult to grind the tapered portions 51e, 51e and the facing surfaces 51t, 51t separately.

Therefore, when the end piece 53a of the spring lever 53 moves while pressing the surfaces of the tapered portions 51e and 51e, the friction increases due to the roughness of the surfaces of the tapered portions 51e and 51 e.

In this case, when the pressing force F is inputted to only one of the 2 buttons 52, it is considered that only one of the end pieces 53a of the spring lever 53 is frictionally caught by the tapered portion 51e and stopped on the tapered portion 51 e.

In contrast, in the timepiece 100 ″ shown in fig. 28A and 28B, since the pipe 51g ' having the engagement hole 51d ', the tapered portion 51e ', and the opposed surface 51h ' is machined by a lathe tool from a component separate from the leg portion 51a ', using an automatic lathe, the tapered portion 51e ' and the opposed surface 51h ' can be formed into smooth surfaces having small surface roughness.

Therefore, even if the pressing force F is input to only one of the 2 buttons 52 ', the end piece 53a of the spring lever 53 does not stop at the tapered portion 51 e', and can be returned to the original position more reliably.

Further, since the tubes 51g ' and 51g ' are made of a material harder than the leg portions 51a ' and 51b ', the problem is less likely to occur that the surface of the tapered portion 51e ' is depressed and the surface state changes due to the end piece 53a of the spring lever 53 pressing the tapered portion 51e ' or the pressing body 54 pressing the tapered portion 51e ' via the end piece 53a, thereby affecting the movement of the end piece 53a of the spring lever 53.

When the tapered portion 51e 'is at an angle of about 30[ degrees ] with respect to the axial direction of the engagement hole 51 d', the following is confirmed: when the restricting member 40 is at the restricting position P1, the pressing operation forces F, F in the opposite directions are inputted to the 2 buttons 52 ', whereby the restricting member 40 is smoothly displaced to the release position P2 by the pressing body 54, and even if the pressing operation force F is inputted only to any one of the 2 buttons 52 ', the end piece 53a of the spring lever 53 temporarily moved to the tapered portion 51e ' is smoothly returned to the original position by the release of the pressing operation force F.

(modification for lengthening engaging teeth)

In the timepieces 100, 100', and 100 ″ according to the embodiments, as shown in fig. 29A and 29B, the engaging teeth 42 of the regulating member 40 may be projected toward the case 20 side rather than the surface 48 facing the case 20.

The distance L2 from the shaft hole 45 to the catch tooth 42 is longer than the distance L1 from the shaft hole 45 to the spring rod hole 46.

Therefore, the engagement teeth 42 are more greatly fluctuated with respect to the teeth 33 of the bezel 30 than the fluctuation of the spring lever 53 with respect to the spring lever hole 46.

Here, as shown in fig. 29A and 29B, by the configuration in which the engagement teeth 42 are projected toward the case 20 side from the surface 48 facing the case 20, it is possible to reliably prevent the engagement state between the engagement teeth 42 and the teeth 33 of the bezel 30 from being unexpectedly released due to a large play therebetween.

In the timepieces 100, 100', and 100 ″ according to the embodiments, the 2 push buttons 52 and 52 are arranged in a straight line so as to face each other, so that the pressing operation forces F, F in opposite directions can be inputted, and in the configuration in which the push buttons are arranged in such a way as to face each other, for example, a combination of a thumb and an index finger, or a thumb and a middle finger is used to easily input the pressing operation force F, F independently to the 2 push buttons 52 and 52.

However, the timepiece of the present invention is not limited to the configuration in which the 2 operation input portions are arranged to face each other, and may be configured to input the pressing operation forces in different directions from each other, or may be configured to input the pressing operation forces in the same direction.

In other words, the timepiece of the present invention may be provided with 2 or more operation input portions capable of inputting pressing operation forces.

In the timepieces 100, 100', and 100 ″ according to the embodiments, the position in the direction is fixed by the sleeve 56 using the shaft 55 that penetrates the insertion leg portions 51a and 51b and the shaft hole 45 of the regulating member 40.

In this case, for example, as shown in fig. 30, a male screw portion (or a female screw portion) 55a is formed at one end portion of the shaft 55, and a screw 55b having a diameter larger than the male screw portion (or the female screw portion) 55a and fastened to the male screw portion (or the female screw portion) 55a is used in combination.

A groove portion 55e for a tool (for example, a parallel screwdriver) for fastening and tightening the male screw portion (or the female screw portion) 55a and the screw 55b is formed in the head of the screw 55 b.

A head portion 55c having substantially the same thickness as the screw 55b is formed at the other end portion of the shaft 55, and a groove portion 55e for a tool, which is the same as the groove portion 55e of the screw 55b, is also formed in the head portion 55 c.

In the shaft support hole 51c of the leg 51A shown in fig. 11A and 11B, the end portion on the 12 th point side is formed into a hole diameter corresponding to the thickness of the screw 55B or the head 55c, and the remaining portion is formed into a hole diameter corresponding to the shaft 55.

Similarly, the shaft support hole 51c on the leg 51b side has an end portion on the 6 th-point side formed into a hole diameter corresponding to the thickness of the screw 55b or the head 55c, and the remaining portion formed into a hole diameter corresponding to the shaft 55.

One end portion of the shaft 55 without the head portion 55c (the end portion formed with the male screw portion (or the female screw portion) 55 a) is inserted into the shaft support hole 51c from the end portion on the 12-point side of the shaft support hole 51c of the leg portion 51a or the end portion on the 6-point side of the shaft support hole 51c of the leg portion 51b, and the shaft 55 is inserted through the shaft support hole 51c of the leg portion 51a, the shaft hole 45 of the regulating member 40, and the shaft support hole 51c of the leg portion 51 b.

Subsequently, the shaft 55 can be attached to the legs 51a and 51b in a state of being positioned in the longitudinal direction by fastening the screw 55b to the male screw portion (or the female screw portion) 55a with a tool.

(examples other than spring bar)

In the timepieces 100, 100', and 100 ″ according to the embodiments, the spring lever 53 is disposed in the regulating member 40 with the spring lever hole 46 formed therein, but the same mechanism may be implemented using a member other than the spring lever 53.

For example, in fig. 13, the spring rod hole 46 may be formed as a blind hole having a hole portion only in the vicinity of the leg portions 51a and 51b without penetrating the center portion thereof, and the pressing bodies 54 and 54 shown in fig. 2 may be attached to the hole portions in the vicinity of the leg portions 51a and 51 b.

In this case, the pressing body 54 is attached such that an end displaced by a spring incorporated in the pressing body 54 is disposed at the same position as the end piece 53a of the spring lever 53.

The end of the pressing body 54 is energized to a state of being extended in the axial direction by a spring incorporated in the pressing body 54, and each end of the 2 pressing bodies 54, 54 functions as a pair of ends which can be displaced to a contracted state, like the end member 53a of the spring lever 53.

In this way, the holding mechanism 50 and the releasing mechanism can be configured by using a member other than the spring lever such as the pressing body 54.

Since the spring lever 53 is formed as one member including the pair of end members 53a and 53a, the spring lever 53 is less likely to cause displacement of the pair of end members 53a and 53a (particularly, displacement in the rotational direction of the regulating member 40), and is also easy to handle and assemble.

(example of case where pressing body is not used)

In the timepieces 100, 100', and 100 ″ according to the embodiments, the pressing body 54 is used, and even if the pressing body 54 is not used, the release mechanism for automatically moving the regulating member 40 in the direction away from the case 20 can be configured by the pressing force applied to the push button 52.

For example, instead of providing the pressing body 54 on the timepiece 100, the end portion of the push button 52 shown in fig. 13 may be formed in a tapered shape when viewed from the end piece 53a side of the spring lever 53.

In this case, the tapered surface may be formed in a shape satisfying the following condition: when a pressing force F is input to the push button 52, the end piece 53a of the spring lever 53 is pushed out in a direction away from the housing 20, not only in the axial direction of the spring lever, but also by the tapered surface formed at the end of the push button 52.

The timepiece of the present embodiment is an example in which the rotation direction of the bezel 30 is operable in the counterclockwise direction, and is not limited to this, and the timepiece of the present embodiment may be applied to a timepiece in which the bezel 30 is rotatable in both the clockwise direction and the counterclockwise direction.

The timepiece of the present embodiment is a diving watch as an example, and the timepiece of the present invention is not limited to a diving watch, and any timepiece having a rotatable bezel does not hinder the application of the timepiece of the present invention
