Contents of the invention

The problem to be solved by this invention lies in that it is provided with such a base body and a rod body rotatably installed on the base body, and is configured to be clamped by turning the rod body down to pass through the belt-shaped state between the two in the state of erecting the rod body. Body and fastened in the belt buckle on this, prevents the belt-shaped body from falling off unexpectedly between the base body and the rod body when the rod body is erected, at least the operation of bringing down the rod body can be carried out with one hand.

In order to solve the above-mentioned problems, this invention uses the buckle as a buckle having the following structures (1) to (7).

(1) It is a buckle for connecting the strip-shaped body to the connected body;

(2) a base body having a mounting portion of a connected body;

(3) It has a rod body rotatably combined on the base body;

(4) The base body has a base and a support portion of a rod protruding from the base;

(5) The rod body has an operating portion protruding from the combined portion of the base body and a clamping portion protruding from the combined portion in a direction different from the operating portion;

(6) by turning down the rod body, the strip-shaped body passing between the base of the base body and the combined portion of the rod body in the state of erecting the rod body is clamped by the clamping portion of the rod body and the base portion of the base body;

(7) Further, on the operating portion of the lever body, a slit passing through the belt-shaped body is formed that is long in the direction of the rotation axis of the lever body.

The strip-shaped body passing between the bases of the rod body from the state of erecting the rod body is drawn out from the inner side of the operation part through the above-mentioned slit provided on the operation part to the outer side of the operation part. By laying down the rod body from the state where the strip-shaped body is pulled out in this way, the strip-shaped body can be clamped between the clamping portion and the base portion of the base to form a fastening to the strip-shaped body. The fastened state is released by erecting the rod body again, and at this time, the belt-shaped body can also be protruded outward from the outer side of the operation part through the above-mentioned slit. At this time, a force in the direction of pulling out the belt-shaped body from the slit acts on the belt, or a force in the direction of pulling the belt-shaped body out of the slit acts on the buckle, or between the belt-shaped body W and the slit. When such a force acts on both sides of the buckle, the protruding end of the gripping portion, the edge portion on the inner side of the operating portion on the slit, and the outer side of the operating portion on the slit are on the belt-shaped body W. the edge of. As a result, when the rod body is erected, when this force acts on the band-shaped body, a force in the direction of laying it down acts on the rod body, and by the action of this force, the rod body rotates at least a predetermined angle part to the laid down position. . In this way, if the rod rotates, the clamping of the strip-shaped body between the protruding end of the clamping part and the base of the base is formed. As a result, the belt-shaped body is prevented from falling off from between the rod body and the base body, and there is no unexpected separation of the belt-shaped body and the buckle. In addition, by grasping the belt-shaped body drawn out from the slit and moving the drawn-out part in a direction close to the base of the base body, it is also possible to use one hand to turn the rod body to the position where it is laid down, so that the belt-shaped body can be rotated with one operation. fastened state.

If the surface where the slit is formed on the operation part of the above-mentioned rod body is formed as a curved surface with the central part of the slit as the bending center, the edges of the slit can be positioned between the inner surface side and the outer surface side of the operation part. One of them closely contacts the central portion side of the strip-shaped body stretched by the above-mentioned force, and the other one closely contacts the edge portion side of the thus stretched strip-shaped body.

If on the operation portion of the above-mentioned rod body, two slits passing through the belt-shaped body that are longer along the rotation axis direction of the rod body are formed at intervals in the protruding direction of the operation portion, then the belt that passes between the rod body and the base can be After the shape body is drawn out from the inner side of the operating part of the rod body to the outer side of the operating part through one of the two slits, the other side of the slit is drawn out to the inner side of the operating part again. When the above-mentioned force is applied, the upright rod body turns to the direction of laying down so as to prevent the strip-shaped body from falling off between the rod body and the base body.

If the center of rotation of the above-mentioned rod body is positioned above the clamping portion in the state where the rod body is put down and is also biased to the opposite side to the extended side of the operating portion than the position directly above the clamping portion, then it can be erected In the state of the rod body, the gap between the base of the base body and the combined part of the rod body is ensured as large as possible, and the gap between the clamping part and the base of the base body is narrowed in the state of the rod body. The ribbon is firmly clamped between the two.

The present invention has the following effects.

According to the belt buckle of this invention, since the strip-shaped body passing between the base body and the rod body also passes through the slit of the operating part of the rod body, the gripping portion of the rod body and the edge of the slit can be adjusted relative to the belt-shaped body when the rod body is erected. The parts are in contact with different positions, so that when the tension acts on the strip body, the vertical rod body is turned to the direction of laying down, thereby preventing the strip body from falling off unexpectedly from between the base body and the rod body. In addition, at least one hand can perform the operation of bringing down the rod body by using the belt-shaped body drawn out through the slit.

The buckle of this embodiment is typically used to connect the end side of the belt-shaped body W to the other end side of the belt-shaped body W or another belt-shaped body W' or the main body of the article through the buckle. Body J is connected in a state where the fastening position can be adjusted.

This buckle consists of a base body 1 and a rod body 2 .

The base body 1 is provided with a mounting portion 10 of the connected body J. As shown in FIG. For example, if the base body 1 is attached to another belt-shaped body W' using the mounting portion 10 of the base body 1, the two belt-shaped bodies W, W' can be connected by a buckle. In addition, if the base is attached to one end side of one belt-shaped body W by using the attaching portion 10 of the base 1, both ends of the one belt-shaped body W can be connected by a buckle to form a combination. In addition, if the base body 1 is attached to a bag body or the like by using the attachment portion 10 of the base body 1, the belt-like body W can be connected to the bag body or the like with a buckle.

Such a base body 1 includes a base portion 11 and a support portion 12 of the rod body 2 protruding from the base portion 11 . In the illustrated example, the base portion 11 is configured in a plate shape each provided with supporting portions 12 at opposing side portions. One side portion 11 a of the base portion 11 that does not include the supporting portion 12 is bent toward the inside of the base portion 11 as it approaches a position approximately in the middle in the longitudinal direction of the side portion 11 a. The support portion 12 is configured in a side plate shape protruding in a direction perpendicular to this. The supporting part 12 starts from the corner where the curved side part 11a and the side part on which the supporting part 12 is formed joins, and ends with a reduced protruding dimension in the middle. The base portion 11 has a tongue-like portion 11 b protruding first from the end of the support portion 12 . On the above-mentioned corner side of such a support portion 12, a shaft hole 12a penetrating the support portion 12 inside and outside is formed. Moreover, the slit 11c which penetrates between a pair of support part 12 is formed in the base side of the tongue-shaped part 11b of the base part 11 in the penetrating state. In the illustrated example, the base is attached to the belt W' by passing the belt W' through the slit 11c and wrapping the belt W' around the tongue-like portion 11b of the base 1. 1. That is, in the example shown in figure, this slit 11c is made to function as the said attachment part 10. As shown in FIG.

The rod body 2 can be rotatably combined on this base body 1 . The rod body 2 includes: an operation part 21 protruding from the combination part 20 of the base body 1; In the illustrated example, the operation unit 21 is configured in a plate shape having a size substantially covering one surface of the base body 1 . The holding portion 22 is formed to penetrate one side portion of the operation portion 21 and protrude from the side portion. In the illustrated example, the holding portion 22 protrudes from the operation portion 21 in a direction substantially perpendicular to the inner surface of the operation portion 21 . . Axle projections 20a are respectively formed on a pair of surfaces located in the thickness direction of the rod body 2 where the operation portion 21 and the clamping portion 22 are joined, and pass through one of the pair of support portions 12, 12 of the base 1. Put one side of the shaft protrusion 20a in 12a, and put the other side of the shaft protrusion 20a in the shaft hole 12a of the other side of the pair of support parts 12, 12 of the base body 1, and the rod body 2 rotates with the shaft protrusion 20a. The center is rotatably combined on the base 1 . That is, in the illustrated example, the joint between the operation unit 21 and the holding unit 22 functions as the combination unit 20 described above. In the illustrated example, a guide groove 12b is formed between the protruding end of the support part 12 of the base body 1 and the shaft hole 12a, and the end of the protruding side of the clamping part 22 on the shaft protrusion 20a of the rod body 2 An inclined surface 20b is formed on it, and while elastically expanding the distance between the pair of supporting portions 12, 12 of the base 1, a gap between the pair of supporting portions 12, 12 is formed by using the guide groove 12b and the inclined surface 20b. Press the rod body 2 until the shaft protrusion 20a enters the shaft hole 12a to form the above combination of the rod body 2 and the base body 1 . The dimension between the shaft protrusion 20a of the rod body 2 and the protruding end 22a of the clamping portion 22 is set to be smaller than that between the shaft hole 12a directly below the shaft hole 12a formed on the support portion 12 of the base body 1 and the base portion 11. The room size is also slightly smaller. In the example shown in the figure, two ribs 11d, 11d passing through a pair of support portions 12, 12 are formed on the base portion 11 of the base body 1 directly below the shaft hole 12a at intervals. When the rod body 2 is inverted, the holding portion 22 of the rod body 2 is located at a position where the protruding end 22a is inserted between the ribs 11d, 11d. At this time, between the two ribs 11d, 11d and the protruding end 22a of the clamping portion 22, a clamping gap S narrower than the thickness of the strip-shaped body constituting fastening is formed. (FIG. 4) Of these two ribs 11d, 11d, the inner surface of the rib 11d located on the formation side of the tongue-shaped portion 11b of the base 1 forms an inclined surface 11e, and the inclined surface 11e goes from the top of the rib 11d toward the inner surface of the rib 11d. The root slopes in a direction that gradually expands the width of the rib.

In addition, in this embodiment, on the outer surface 22b of the clamping portion 22 continuous with it from the outer surface 20c of the combination portion 20 of the rod body 2, a curvature is applied which follows the curvature of the curved edge portion 11a of the base body 1. In addition, the operating part 21 of the rod body 2 has a large width at its front end side and a small width at its base side. Both edge parts of the large place.

Moreover, in the buckle of this embodiment, in the state where the rod body 2 is erected, that is, in the state where the inner surface 21b of the operation portion 21 of the rod body 2 is separated from the base 11 of the base body 1, the rod body 2 is brought down by turning, that is, , turn the inner surface 21b of the operating part 21 of the rod body 2 to a position close to the base 11 of the base body 1, so that the strip-shaped body W passing between the base part 11 of the base body 1 and the combination part 20 of the rod body 2 is clamped by the rod body 2 The holding part 22 and the base part 11 of the base body 1 are clamped.

In the illustrated example, when the rod body 2 is erected, a gap wider than the thickness of the strip-shaped body W is formed between the outer surface 22b of the clamping portion 22 and one surface of the base portion 11, and the gap is used to erect the rod body. 2, such a strip-shaped body W can pass between the base body 1 and the rod body 2.

In addition, in the buckle of this embodiment, a slit 21c passing through the belt-shaped body W is formed in the operation portion 21 of the lever body 2, which is long in the direction of the rotation axis x of the lever body 2 .

Specifically, in the illustrated example, on the front end side of the operation part 21 of the rod body 2, that is, on the side opposite to the side connected to the clamping part 22, a strip is provided in a state penetrating the inside and outside of the operation part 21. A slit 21c. The width of the slit 21c is set to be approximately equal to or slightly larger than the thickness of the strip-shaped body W passing therethrough.

In addition, such a slit 21c is formed in an arc shape in its longitudinal direction.

Specifically, in the illustrated example, such a slit 21 c is formed in an arc shape so that the base side of the rod body 2 , that is, the connection side with the clamping portion 22 is curved outside.

In addition, in this embodiment, the surface of the operation portion 21 of the lever body 2 where the slit 21c is formed is formed as a curved surface with the center of the slit 21c as the center of curvature.

Specifically, in the illustrated example, the front end side of the operation portion 21 of the rod body 2 is formed into a curved curved surface, so that both the inner surface 21b and the outer surface 21a are moved toward the center of the rod body 2, and the inner surface 21b It gradually approaches the outer side, and the outer surface 21a gradually protrudes outward. (Figure 14)

From the state where the rod body 2 is erected, the strip-shaped body W between the rod body 2 and the base body 1 is drawn from the inner surface 21b side of the operation part 21 to the outside of the operation part 21 through the above-mentioned slit 21c provided on the operation part 21. 21a side. By laying down the rod body 2 from the state where the strip-shaped body W is pulled out in this way, the strip-shaped body W can be clamped between the clamping portion 22 and the base portion 11 of the base body 1 to form fastening to the strip-shaped body W. This fastened state is released by erecting the lever body 2 again, and at this time, the strip-shaped body W may protrude outward from the outer surface 21a side of the operation portion 21 through the slit 21c. At this time, a force in the direction of pulling out the belt-shaped body W from the slit 21c acts on the belt-shaped body W, or a force in a direction in which the belt-shaped body W is pulled out from the slit 21c acts on the buckle, or When such a force acts on both the belt-shaped body W and the buckle, the protruding end 22a of the holding portion 22 contacts the edge of the inner surface 21b side of the operation portion 21 on the slit 21c on the belt-shaped body W. part 21d and the edge part on the outer surface 21e side of the operation part 21 on the slit 21c. (FIG. 14) As a result, when the rod body 2 is erected as shown in FIG. 14, when this force acts on the strip-shaped body W, etc., the rod body 2 acts on the rod body 2. The force in the direction of putting it down, by the action of this force, The rod body 2 rotates at least a predetermined angle part to the laid down position. In this way, if the rod body 2 rotates, the strip-shaped body W is clamped between the protruding end 22a of the clamping portion 22 and the base portion 11 of the base body 1 . Thereby, the belt-shaped body W is prevented from coming off from between the rod body 2 and the base body 1, and the belt-shaped body and the buckle are not separated unexpectedly. In addition, by grasping the strip-shaped body W drawn out from the slit 21c and moving the drawn-out part Wa in a direction close to the base 11 of the base body 1, the rod body 2 can be turned to the down position with one hand and made with one operation. The state of fastening to the ribbon body.

Especially in this embodiment, the slit 21c is formed in an arc shape in its longitudinal direction, and the surface of the operation portion 21 of the lever body 2 where the slit 21c is formed is formed so that the central portion of the slit 21c is The curved surface of the center is bent, so that the edge portion of the slit 21c can be tightly contacted on the central portion side of the strip-shaped body W stretched by the above-mentioned force on either the inner surface 21b side or the outer surface 21a side of the operation portion 21, And wherein the other side closely contacts the edge portion side of the strip-shaped body W stretched in this way, when the above-mentioned force is applied, the upright rod body 2 can be reliably rotated in the direction of laying it down.

In the illustrated example, on the outer surface 21a side of the operating portion 21 of the rod body 2, at the central portion of the strip-shaped body W that is stretched by the above-mentioned force to be aligned in the width direction, the contact slit 21c is located on the operating portion 21. The edge portion on the front end side of the rod body, and on the inner surface 21b side of the operating portion 21 of the rod body, on both edge portions of this strip-shaped body W, respectively contact the edge portion of the slit 21c on the base side of the operating portion 21 .

Different from the illustrated example, it is also possible to form two narrow passages passing through the belt-shaped body W that are longer in the direction of the rotation axis x of the rod body 2 on the operation part 21 of the rod body 2 in the direction of protrusion of the operation part 21 at intervals. seam to form the buckle.

In this case, after the strip-shaped body W passing between the rod body 2 and the base body 1 is drawn out from the inner surface 21b side of the operation part 21 of the rod body 2 to the outer side of the operation part 21 through one of the two slits, The other side of the slit is led out to the inner surface 21b side of the operation part 21 again. In this case, the rod body 2 erected when the above-mentioned force is applied can also be rotated in the direction of laying down, thereby preventing the strip-shaped body W from coming out of the rod body 2. and the shedding between the substrate 1.

FIG. 15 shows a configuration in which the center of rotation of the rod body 2 is located above the clamping portion 22 in the state where the rod body 2 is laid down, and is further biased toward the side opposite to the protruding side of the operating portion 21 than the position directly above the clamping portion 22. Example of side position.

In this example, two ribs 11d, 11d are formed directly below the shaft hole 12a formed on the support portion 12 of the base 1, and a rib 11d is provided adjacent to one of the two ribs 11d, 11d. The slit 11c' that runs through the length between the two supporting parts 12, 12, and between the other side of the two ribs 11d, 11d and the other side of the side where the supporting part 12 is not formed on the base 1, is spaced Two slits 11c" forming the mounting portion 10 are provided at intervals.

In this example, the protruding end 22 a of the clamping portion 22 has an inclined surface formed such that its protruding dimension gradually increases toward the protruding side of the operation portion 21 . Furthermore, in this example, the center of the short cylindrical shaft protrusion 20a formed on the rod body 2 is located on the side opposite to the protruding side of the operation part 21 from the position directly above the lower end 22c of the inclined surface. position.

In the case of constituting the rod body 2 in this way, it is possible to ensure as large a space S as possible between the base of the base body 1 and the combined portion 20 of the rod body 2 in the state where the rod body 2 passes through the strip-shaped body W, and when the rod body 2 is put down, In this state, the gap between the clamping portion 22 and the base portion 11 of the base body 1 is narrowed to securely clamp the passing strip W between the two. (FIG. 16) That is, it is easy to pass the strip-shaped body W between the base portion 11 of the base body 1 and the combined portion 20 of the shaft body 2 in the state where the shaft body 2 is erected, and even if the strip-shaped body W is thick to a certain extent, it can be constituted. relative to its clasp. In addition, when the rod body 2 that has been laid down is erected and the fastening of the belt-shaped body W is released, the clamping portion 22 is not positioned directly below the rotation center of the rod body 2 but is pressed against the rotation front end side of the rod body 2 at this time. On the belt-shaped body W, the operation of erecting the rod body 2 can be performed with a relatively small force.
