However, with conventional umbrellas such as those disclosed in Non-Patent Document 1, when carrying luggage while the umbrella is folded, one hand is occupied by the umbrella. Therefore, if you operate your smartphone while holding luggage in both hands or while holding onto a strap on a bus or train, there is a problem that there is no suitable place to temporarily put the umbrella, and the umbrella gets in the way. In particular, with smartphones, people are often seen looking at their smartphones even while standing on trains, and nowadays, smartphones are indispensable no matter the environment.

The present invention was made in consideration of these problems, and its purpose is to provide an umbrella that does not get in the way when carried in a folded state, leaving both hands free for other purposes.

In order to solve the above problems, the present invention provides an umbrella comprising a bone section that supports the fabric, a shaft section that supports the bone section so that it can be opened and closed, and a handle section that is attached to the tip of the shaft section, the handle section comprising a grip section that extends along the shaft section, an expandable section that is connected to the grip section and expands and contracts linearly in a direction different from the extension direction of the grip section, and a hook section that is connected to the expandable section and whose distance from the grip section changes as the expandable section expands and contracts.

With this configuration, when carrying the umbrella in a folded state and both hands are full, the extendable part of the handle can be extended to hang the umbrella on the shoulder, leaving both hands free for other purposes and allowing the umbrella to be carried without getting in the way.

The present invention can be applied in various ways. The following application examples can be implemented in appropriate combination.
For example, the telescopic portion may include an intermediate portion having a hollow portion with one end connected to at least one of the grip portion and the hook portion and the other end opened, and an extension portion that is accommodated in the hollow portion so as to be able to appear and disappear through the opening of the intermediate portion.

The stretchable section is stretchable by connecting one end of the middle section to at least one of the grip section and the hook section. Three stretchable configurations are described below.

In the first configuration, the telescopic section may include an intermediate section with a hollow section whose one end is connected to the grip section and whose other end is open, and an extension section that is accommodated in the hollow section so as to be able to appear and disappear through the opening of the intermediate section. With this configuration, the hook section of the handle section and the extension section are integrated, allowing the telescopic section to be extended and retracted linearly from the opening. Therefore, the hook section of the handle section can move in the telescopic direction.

In a second configuration, the telescopic section may include an intermediate section with a hollow section, one end of which is connected to the hook section and the other end of which is open, and an extension section that is accommodated in the hollow section and can be inserted and removed through the opening of the intermediate section. With this configuration, the grip section and the extension section of the handle section are integrated, allowing the telescopic section to be extended and retracted linearly from the opening. Thus, the hook section and the intermediate section are integrated in the handle section and can move in the telescopic direction.

As a third configuration, the telescopic section may include an approximately half of the intermediate section, one end of which is connected to the hook section and the grip section, and the other end of which is separated approximately in the center and has an opening in a hollow section, and an extension section that is accommodated in the hollow section through the opening of the intermediate section so that it can be inserted and removed from the hollow section. With this configuration, the grip section of the handle section and the extension section of the approximately half of the intermediate section, and the hook section and the extension section of the approximately half of the intermediate section are connected, and the telescopic section can be linearly telescopically extended and retracted from the opening. Thus, the hook section and the approximately half of the intermediate section are integrated in the handle section and can move in the telescopic direction.

The handle portion is generally J-shaped, and the telescopic portion may be telescopic in an arc rather than a straight line, provided that it is telescopic. Note that the preferred drawings and embodiments of the present invention are based on the first configuration. As the telescopic portion is a component that has substantially the same functional configuration, duplicated descriptions of the second and third configurations will be omitted.

In addition, multiple extension parts may be provided overlapping in the radial direction, and the multiple extension parts may protrude sequentially from the opening of the middle part. With this configuration, the length by which the extension part expands and contracts can be greatly changed depending on the number of protruding extension parts, making it possible to accommodate any thickness of the shoulder.

A magnet part may be provided at the other end of the intermediate part, and a steel part provided in the extension part may be attracted to the magnet part, so that the extension part is maintained in a state where it protrudes from the intermediate part or is stored in the intermediate part. With this configuration, the extension part is maintained in a state where it protrudes from the intermediate part, so that the extension part does not inadvertently appear or disappear from the intermediate part. Furthermore, when the extension part is pulled out due to its fixation with the magnet part, it can be pulled out instantly.

Furthermore, a fixing means may be provided that can fix the extension portion to the intermediate portion at a position where the extension portion is extended or retracted to any length. This configuration is easy to use.

The fixing means may also include a moving knob provided on the extension section that can operate the movement of the extension section in the protruding and retracting direction, a guide section provided on the intermediate section that guides the movement of the moving knob, and a locking section provided on the guide section that locks the moving knob. With this configuration, the movement and locking of the extension section can be easily operated by the moving knob, the guide section, and the locking section.

The fixing means may also include a rotary knob provided on the extension section that can operate the movement of the extension section in the protruding and retracting direction and can regulate the movement of the extension section by rotating it, and a guide section provided on the intermediate section that guides the movement of the rotary knob. With this configuration, the extension section can be easily moved and locked by the rotary knob and guide section.

The fixing means may also be configured with a female screw hole formed continuously from one end of the hollow portion to the opening at the other end, and a male screw formed on the outer periphery of the extension portion and screwed into the female screw hole. With this configuration, the extension portion can be extended and retracted from the middle portion and engaged simply by rotating the extension portion, making the construction and operation of the telescopic portion easy.

According to the present invention, when carrying an umbrella in a folded state, when carrying luggage with both hands, or when you want to operate your smartphone while standing and holding on to a strap on a bus or train, the handle of the umbrella can be extended and widened to allow the umbrella to be hung on the shoulder, providing a convenient umbrella that leaves both hands free for other purposes and does not get in the way. Other effects of the present invention will be described in the description of the embodiment of the invention below.

FIG.

A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. Note that in this specification and drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

First Embodiment
The umbrella 100 of the first embodiment will be described with reference to Figures 1 and 2. First, the overall configuration of the umbrella 100 will be described with reference to Figures 1 and 2. Figure 1 is a diagram showing the configuration of the umbrella 100. Figure 2 is a diagram for explaining the configuration when the extension section 140 is extended.

As shown in Figures 1 and 2, the umbrella 100 comprises a rib that supports the fabric, a shaft 110 that supports the rib so that it can be opened and closed, and a handle 120 provided at the tip of the shaft 110. The handle 120 comprises a grip 130 that extends along the shaft 110, an expandable section 140 that is connected to the grip 130 and expands and contracts linearly in a direction different from the extension direction of the grip 130, and a hook 150 that is connected to the expandable section 140 and whose distance from the grip 130 changes as the expandable section 140 expands and contracts. Each component will be described in detail below.

The fabric and ribs not shown in FIG. 1, and the shaft portion 110 partially shown in FIG. 1, can be configured in the same way as the fabric, ribs, and shaft of a typical umbrella, so detailed explanations will be omitted here.

(Handle portion 120)
1, the handle portion 120 is configured to include a grip portion 130 extending along the shaft portion 110, an expandable portion 140 connected to the grip portion 130 and linearly expanding and contracting in a direction different from the extension direction of the grip portion 130, and a hook portion 150 connected to the expandable portion 140 and changing the distance between the grip portion 130 and the hook portion 150 due to the expansion and contraction of the expandable portion 140. The material of the handle portion 120 can be a general one, but any usable material such as a resin material or a stainless steel material may be used.

(Grip portion 130)
The grip portion 130 is a portion that a user generally holds with his/her hand when using the umbrella 100. As shown in Fig. 1, the grip portion 130 is disposed so as to extend along the shaft portion 110, and is a long portion having one end connected to the tip of the shaft portion 110. An expandable portion 140 extends from the other end of the grip portion 130 in a substantially vertical direction and is formed integrally therewith.

(Expandable section 140)
The extendable section 140 is a section that extends and retracts at the middle section 141 in order to hang the hook section 150 of the handle section 120 on the shoulder. As shown in Fig. 1 and Fig. 2, the extendable section 140 is configured to include a middle section 141 having one end connected to the grip section 130 and the other end having a hollow section 141b with an opening 141a, and a first extension section 142 and a second extension section 143 that are housed in the hollow section 141b so as to be able to appear and disappear through the opening 141a of the middle section 141. The material of the extension section may be any usable material, such as a resin material or a stainless steel material.

As shown in Figs. 1 and 2, the intermediate portion 141 is a long portion disposed between the grip portion 130 and the hook portion 150. The intermediate portion 141 is configured with a hollow portion 141b whose one end is connected to the grip portion 130 and whose other end has an opening 141a. The hollow portion 141b is formed from the opening 141a of the intermediate portion 141 to the vicinity of the grip portion 130, but if the intermediate portion 141 is extended in a substantially T-shape in the opposite direction to the grip portion, the stretchable portion 140 can be formed to the vicinity of the end of this extension. In this case, the length of the extension portion can be made even longer. The shape of the intermediate portion 141 and the hollow portion 141b can be designed to be either circular or polygonal in cross section.

As shown in Figures 1 and 2, the first extension portion 142 and the second extension portion 143 are arranged so as to overlap in the radial direction, and the first extension portion 142 and the second extension portion 143 are configured so as to protrude sequentially from the opening 141a of the intermediate portion 141.

The first extension portion 142 is configured in a cylindrical shape of approximately the same length as the hollow portion 141b, and is slidably fitted into the hollow portion 141b. The first extension portion 142 is prevented from slipping out of the hollow portion 141b, and is prevented from falling off from the intermediate portion 141. The prevention of the first extension portion 142 from slipping out of the hollow portion 141b can be designed in any manner using a well-known method. For example, rubber or the like may be provided on the outer periphery of the rear end portion, which is the end portion of the first extension portion 142 on the grip portion 130 side, to prevent it from slipping out by friction.

The second extension portion 143 is configured to have approximately the same shape as the inner circumference of the first extension portion 142, is configured to be rod-shaped with approximately the same length, and is slidably fitted into the first extension portion 142. When the vicinity of the rear end portion, which is the end portion on the grip portion 130 side of the second extension portion 143, is pulled out to the vicinity of the front end portion, which is the end portion on the opening 141a side of the first extension portion 142, the first extension portion 142 is configured to be pulled out in conjunction with the second extension portion 143. Note that the extension portion of the telescopic portion 140 may be composed of only the first extension portion 142.

(Hook portion 150)
The hook portion 150 is normally hook-shaped for hanging on the arm, etc., but when the stretchable portion 140 of the middle portion 141 is stretched and hung on the shoulder, it prevents the bag from falling off the shoulder. As shown in Figures 1 and 2, the hook portion 150 is provided at the front end of the second extension portion 143. The hook portion 150 has at least a portion provided in parallel with the opposite side of the grip portion 130, and when the stretchable portion 140 is placed on the shoulder, the shoulder is pinched between the hook portion 150 and the grip portion 130, thereby restricting movement in the front-rear direction.

In this embodiment, the hook portion 150 is a straight member, but it may be a curved member. Furthermore, by making it an elastically deformable member and deforming it in the extension direction of the expandable portion 140, the width of the portion placed on the shoulder can be made greater than or equal to the width of the expandable portion 140, or it can be made to fit the shape of the shoulder. The configuration for elastically deforming the hook portion 150 can be arbitrarily designed by well-known methods, for example, by covering a bendable iron or aluminum wire core with a rubber material, by combining ABS and an aluminum alloy, or by using a flexible pipe.

In order to prevent the stretchable portion 140 and the hook portion 150 from slipping off the shoulder, it is preferable that they are covered with a non-slip material. For example, even if the stretchable portion 140 and the hook portion 150 are not securely attached to the shoulder, the non-slip covered portion of the tip of the hook portion 150 or a part of the non-slip covered portion of the stretchable portion 140 only comes into contact with the shoulder, and this has the effect of preventing slipping off the shoulder. Examples of non-slip materials include rubber materials, silicone materials, polyurethane materials, acrylic elastic materials, non-slip elastic resin materials, etc., but are not limited to these as long as they have an anti-slip effect and can be used.

The above describes the configuration of the umbrella 100. Next, the operation of the umbrella 100 will be described with reference to Figures 1 and 2 again. When the umbrella 100 is put up, held in the hand, or stored away, the telescopic section 140 can be retracted as shown in Figure 1. To retract the telescopic section 140, the first extension section 142 and the second extension section 143 are stored in the hollow section 141b of the middle section 141. In this state, the telescopic section 140 can be used as a normal handle in its shortest state.

When carrying the umbrella 100, in addition to holding the handle portion 120 in the hand, the extension portion 140 can be extended and hung on the shoulder. When carrying the umbrella 100 on the shoulder, as shown in FIG. 2, first, the second extension portion 143 is pulled out from the middle portion 141 through the opening 141a. When the rear end portion of the second extension portion 143 is pulled out to the front end portion of the first extension portion 142, the first extension portion 142 is pulled out in conjunction with the second extension portion 143. In this way, the extension portion 140 can be extended, so that the extension portion 140 and the hook portion 150 can be hung on the shoulder.

The length to which the stretchable section 140 is stretched can be changed by adjusting the amount by which the first stretchable section 142 and the second stretchable section 143 are pulled out from the middle section 141. The length of the stretchable section 140 can be adjusted, for example, by pulling out only the second stretchable section 143 from the middle section 141, or by adjusting the amount by which the first stretchable section 142 and the second stretchable section 143 are pulled out.

(Effects of the First Embodiment)
As described above, according to this embodiment, when carrying umbrella 100 in a folded state, the extension section 140 can be extended and hung over the shoulder, allowing both hands to be used for other purposes and allowing the umbrella 100 to be carried without getting in the way.

In addition, the first extension section 142 and the second extension section 143 are accommodated in the hollow section 141b through the opening 141a of the middle section 141 so that they can be inserted and removed, allowing the extension section 140 to be linearly extended and retracted.

In addition, the length by which the stretchable section 140 stretches can be greatly changed depending on the number by which the first extension section 142 and the second extension section 143 are protruded, making it possible to accommodate any thickness of the shoulder.

In addition, by providing a hook portion 150 at the end of the stretchable portion 140, it is possible to prevent the stretchable portion 140 from slipping off the shoulder.

Second Embodiment
The umbrella 200 of the second embodiment will be described with reference to Figures 3 and 4. Figure 3 is a diagram showing the configuration of the umbrella 200. Figure 4 is a diagram for explaining the configuration when the extension section 240 is extended. Note that in this embodiment, the configuration of the extension section 240 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the components that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130.

As shown in Figures 3 and 4, the umbrella 200 has an expandable section 240 that is composed of an intermediate section 241 and an extension section 242. The intermediate section 241 has a magnet section 244 at the other end. The magnet section 244 has an insertion hole 244a through which the extension section 242, which will be described later, can be inserted. Since the insertion hole 244a is smaller than the opening 241a of the intermediate section 241, the edge of the magnet section 244 is exposed in the space near the periphery of the opening 241a. The magnet section 244 may be provided over the entire other end of the intermediate section 241, or may be provided over only a portion of it.

As shown in Figures 3 and 4, the extension 242 is configured to be thick enough not to come into contact with the hollow portion 241b. Near the rear end, the rear end, and the tip of the extension 242, a first steel portion 245, a second steel portion 246, and a third steel portion 247 that slidably fit into the hollow portion 241b are provided. When the extension 242 protrudes from the middle portion 241, the first steel portion 245 is attracted to the magnet portion 244 to maintain the protruding state of the extension 242. When the extension 242 is completely accommodated in the hollow portion 241b, the third steel portion 247 is attracted to the magnet portion 244 to maintain the accommodated state.

In this embodiment, the first steel part 245 and the third steel part 247 may be magnet parts. The second steel part 246 is provided so that the part remaining in the hollow part 241b when the first steel part 245 and the magnet part 244 are attracted to each other prevents the extension part 242 from tilting. In this embodiment, the second steel part 246 is made of steel, but the material is not limited to steel.

As shown in Figures 3 and 4, the third steel part 247 is disposed around the hook part 250 where the extension part 242 is connected. When the extension part 242 is completely housed in the hollow part 241b, the third steel part 247 is attracted to the magnet part 244, so that the hook part 250 is fixed to the tip of the middle part 241.

The above describes the configuration of the umbrella 200. Next, the operation of the umbrella 200 will be described with reference to Figures 3 and 4 again. To retract the telescopic section 240, the extension section 242 is housed in the hollow section 241b of the middle section 241, as shown in Figure 3. At this time, the third steel section 247 of the hook section 250 is attracted to the magnet section 244, and this state is maintained. Therefore, the extension section 242 does not inadvertently protrude from the middle section 241.

To extend the telescopic section 240, as shown in FIG. 4, the extension section 242 is pulled out from the middle section 241 through the insertion hole 244a of the magnet section 244. At this time, the first steel section 245 and the second steel section 246 of the extension section 242 slide in contact with the hollow section 241b, so that the extension section 242 is prevented from tilting and is smoothly pulled out. When the first steel section 245 of the extension section 242 abuts against the magnet section 244, the first steel section 245 and the magnet section 244 are attracted to each other, and the extension section 242 is restricted from being pulled out any further. In this way, the extension section 242 maintains its pulled-out state. By extending the telescopic section 240 in this way, the umbrella 100 can be hung on the shoulder and both hands can be used for other purposes.

(Effects of the Second Embodiment)
As described above, according to this embodiment, the magnet portion 244 of the intermediate portion 241 is attracted to the first steel portion 245 of the extension portion 242, and the extension portion 242 is maintained in a protruding state from the intermediate portion 241, so that the extension portion 242 does not inadvertently appear or disappear from the intermediate portion 241.

In addition, the magnet portion 244 of the middle portion 241 is attracted to the first steel portion 245 of the hook portion 250, so that the hook portion 250 does not easily come off the middle portion 241 when the telescopic portion 240 is retracted. Therefore, when the umbrella 200 is put up, the shape of the handle portion 220 can be maintained, making it easy to use.

Third Embodiment
The umbrella 300 of the third embodiment will be described with reference to Figs. 5 and 6. Fig. 5 is a diagram showing the configuration of the umbrella 300. Fig. 5 is a diagram for explaining the configuration of the extension section 340. Fig. 6 is a diagram for explaining the configuration when the extension section 340 is extended. Note that in this embodiment, the configuration of the extension section 340 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the components that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130.

As shown in Figures 5 and 6, the umbrella 300 of this embodiment is provided with a fixing means 343 that can fix the extension part 342 to the middle part 341 at a position where it is extended and retracted to any length. The fixing means 343 is provided with a moving knob 344 that is provided on the extension part 342 and can operate the movement of the extension part 342 in the extending and retracting direction, a guide part 345 that is provided on the middle part 341 and guides the movement of the moving knob 344, and a locking part 346 that is provided on the guide part 345 and locks the moving knob 344.

As shown in Figs. 5 and 6, the moving knob 344 is provided near the rear end of the extension 342 and protrudes above the intermediate portion 341 via the guide portion 345. The moving knob 344 is wider than the guide portion 345, and is restricted from entering the hollow portion 341b from the guide portion 345. Between the moving knob 344 and the extension 342, a locked portion 344a is formed by a convex leaf spring that engages with the locking portion 346. When the upper surface of the moving knob 344 is pressed in the moving direction with a finger, the locked portion 344a is depressed when it hits the sawtooth portion of the locking portion 346, and moves past the locking portion 346 and along the guide portion 345.

As shown in Figures 5 and 6, the guide section 345 is an opening that extends from one end of the upper part of the intermediate section 341 toward the other end so as to communicate with the hollow section 341b. A moving knob 344 is disposed on the upper part of the guide section 345, and guides the movement of the moving knob 344 along the guide section 345.

As shown in Figures 5 and 6, the locking portion 346 is formed in a continuous sawtooth shape over almost the entire length of one side of the guide portion 345. The locked portion 344a of the moving knob 344 can be engaged at any position of the locking portion 346, so the extension portion 342 can be fixed to the intermediate portion 341 at a position where it is extended and retracted to any length.

The above describes the configuration of the umbrella 300. Next, the operation of the umbrella 300 will be described with reference to Figures 5 and 6 again. To retract the telescopic section 340, as shown in Figure 5, the movable knob 344 is moved to one end of the guide section 345, and the extension section 342 is housed in the hollow section 341b of the middle section 341. At this time, the locked section 344a on the far side engages with the locking section 346, restricting the movement of the movable knob 344. Therefore, the telescopic section 340 remains in the retracted state.

To extend the telescopic section 240, as shown in FIG. 6, the movable knob 344 is pressed and moved to the other end of the guide section 345. Then, the extension section 342 is pulled out from the opening 341a together with the movable knob 344. When the movable knob 344 is moved to any position, the locking section 346 and the locked section 344a lock at that position, so that the extension section 342 is held in any protruding position.

(Effects of the Third Embodiment)
As described above, according to this embodiment, the fixing means 343 is provided that can fix the extension portion 342 to the intermediate portion 341 at a position where the extension portion 342 is extended or retracted to any desired length, which makes the present embodiment easy to use.

In addition, the movement knob 344, guide portion 345, and locking portion 346 allow easy operation of moving and locking the extension portion 342.

Fourth Embodiment
The umbrella 400 of the fourth embodiment will be described with reference to Figures 7 and 8. Figure 7 shows the configuration of the umbrella 400, where (a) is a plan view, (b) is a front view, and (c) is a cross-sectional view of the vicinity of the rotating knob 444. Figure 8 is a view for explaining the configuration when the extension part 440 is extended, where (a) is a plan view, and (b) is a front view. Note that in this embodiment, the configuration of the extension part 440 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the parts that can be configured in the same way as the first embodiment, such as the shaft part 110 and the grip part 130.

As shown in Figures 7 and 8, the umbrella 400 of this embodiment is provided with a fixing means 443 on the extension section 440 that can fix the extension section 442 to the middle section 441 at a position where it is extended and retracted to any length. The fixing means 443 is provided on the extension section 442 and is capable of manipulating the movement of the extension section 442 in the extending and retracting direction, and is configured to include a rotating knob 444 that can regulate the movement of the extension section 442 by rotating it, and a guide section 445 that is provided on the middle section 441 and guides the movement of the rotating knob 444.

As shown in Figs. 7 and 8, the rotating knob 444 has a male screw portion 444a protruding in the axial direction. The male screw portion 444a is inserted into the hollow portion 441b from the outside of the intermediate portion 441 via the guide portion 445, and is screwed into a female screw hole 442a provided near the rear end of the extension portion 442. The rotating knob 444 protrudes above the intermediate portion 441 and can be rotated. By rotating the rotating knob 444 in one direction, the extension portion 442, which is prevented from rotating, is pressed against the wall of the hollow portion 441b, restricting the movement of the extension portion 442. In addition, by rotating the rotating knob 444 in the other direction, the extension portion 442 moves in a direction away from the wall of the hollow portion 441b.

As shown in Figures 7 and 8, the guide section 445 is an opening that extends from one end of the upper part of the intermediate section 441 toward the other end so as to communicate with the hollow section 441b. The width of the guide section 445 is configured to be slightly larger than the diameter of the male thread section 444a. The other end of the guide section 445 is formed with a portion that prevents the extension section 442 from moving.

The above describes the configuration of the umbrella 400. Next, the operation of the umbrella 400 will be described with reference to Figs. 7 and 8 again. To retract the telescopic portion 440, as shown in Fig. 7, the rotating knob 444 is rotated in the other direction to move the extension portion 442 away from the wall of the hollow portion 441b, making the extension portion 442 movable. Then, the rotating knob 444 is moved to one end of the guide portion 445 to accommodate the extension portion 442 in the hollow portion 441b. After this, the rotating knob 444 is rotated in one direction to press the extension portion 442 against the wall of the hollow portion 441b, restricting the movement of the extension portion 442. Thus, the telescopic portion 440 is held in a retracted state.

To extend the telescopic portion 440, as shown in FIG. 8, the rotating knob 444 is rotated in the other direction to move the extension portion 442 away from the wall of the hollow portion 441b, making the extension portion 442 movable. The rotating knob 444 is then moved to the other end of the guide portion 445. Then, the extension portion 442 is pulled out of the opening 441a together with the rotating knob 444. After moving the rotating knob 444 to a desired position, it is rotated in one direction to press the extension portion 442 against the wall of the hollow portion 441b, restricting the movement of the extension portion 442. Thus, the extension portion 442 is held in a desired protruding position.

(Effects of the Fourth Embodiment)
As described above, according to this embodiment, the extension portion 442 can be easily moved and locked by the rotating knob 444 and the guide portion 445 .

Fifth Embodiment
The umbrella 500 of the fifth embodiment will be described with reference to Figs. 9 and 10. Fig. 9 is a diagram showing the configuration of the umbrella 500. Fig. 10 is a diagram for explaining the configuration when the extension section 540 is extended. Note that in this embodiment, the configuration of the extension section 540 is different from that of the first embodiment, and the following description will focus on the differences from the first embodiment. The same reference symbols may be used to omit redundant description of the components that can be configured in the same way as the first embodiment, such as the shaft section 110 and the grip section 130.

As shown in Figures 9 and 10, in the umbrella 500 of this embodiment, the hollow portion 541b of the middle portion 541 is configured with a female thread. In addition, the extension portion 542 is formed with a male thread that screws into the hollow portion 541b. A hook portion 550 is provided at the front end of the extension portion 542.

The configuration of the umbrella 500 has been described above. Next, the operation of the umbrella 500 will be described with reference to Figures 9 and 10 again. To retract the telescopic portion 540, the hook portion 550 is rotated in one direction, and the extension portion 542 is housed in the hollow portion 541b as shown in Figure 9. Thus, the telescopic portion 540 is held in a retracted state.

To extend the telescopic portion 540, the hook portion 550 is rotated in the other direction as shown in FIG. 10. Then, the extension portion 542 moves in the direction protruding from the middle portion 541. When the rotation of the hook portion 550 is stopped after the extension portion 542 has been moved to the desired length, the movement of the extension portion 542 is restricted. Thus, the extension portion 542 is held at the desired protruding position. In addition, the extension portion 542 may be colored red, for example, from one end to a position about 3 cm in front, to prevent it from slipping out of the opening when protruding. The colored portion makes it easier to grasp the position of the remaining extension portion 542.

Furthermore, at least the middle portion 541 may be made of a transparent material. By being able to see the extension portion 542, it becomes easier to grasp the position of the extension portion 542. Examples of transparent materials include polyethylene, silicone, FRP, polyurethane, polycarbonate, etc., but any usable material may be used and there is no particular limitation. Other portions may also be made of a transparent material if usable. The above points are similar to other embodiments.

(Effects of the Fifth Embodiment)
As described above, according to this embodiment, the extension portion 542 can be caused to protrude from and engage with the intermediate portion 541 simply by rotating the extension portion 542, so that the structure and operation of the extension portion 540 is easy.

Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an example. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention.

For example, in the first embodiment, the expandable portion 140 is configured to expand and contract in a direction approximately perpendicular to the circular direction of the grip portion 130, but the present invention is not limited to this example. It can be designed in any way so long as it expands and contracts in a direction different from the extension direction of the grip portion. For example, it may be designed to expand and contract diagonally downward or upward relative to the extension direction of the grip portion. The same applies to the second to fifth embodiments.

In addition, in the first embodiment, the first extension portion 142 and the second extension portion 143 of the telescopic portion 140 are capable of emerging and retracting from the hollow portion 141b of the middle portion 141, but the present invention is not limited to this example. For example, the extension portions may be disposed on the outer periphery of the middle portion and be capable of emerging and retracting from the outer periphery of the middle portion. The same applies to the second to fifth embodiments.

The embodiments, application examples, modifications, etc. described above can be implemented in any combination.
