BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a push type hooking device used for a belt for clothes, a band for hanging pants, and the like.

[0002]

2. Description of the Related Art In recent years, a receiving metal fitting and an inserting metal fitting have been attached to both ends of a belt and the like as a hook for a clothing belt so that the receiving metal fitting and the inserting metal fitting can be connected or disconnected with one touch. A so-called push-type hooking metal fitting is widely used.

Conventionally, as this kind of hanging metal fitting, for example, one having a structure disclosed in Japanese Utility Model Publication No. 2-16677 is known, which is composed of a receiving metal fitting 8 and an inserting metal fitting 9. . Specifically, as shown in FIG. 12 and FIG. 13, the receiving metal 8 is provided with a substrate 10 having bent pieces 10a and guide grooves 10b on both side edges, and slidably in a state of facing the substrate 10. The projection 11a and the engaging groove 11b are provided at the front end portion, and the projection 11c is provided at the rear end portion, and both ends of the rear end portion are substantially L protruding outward from the guide groove 10b of the substrate 10.
Two V-shaped slide locking pieces 11 are provided at the rear end of the substrate 10, and have a semicircular groove 12a and a wide groove 12b on the inner side and a belt locking on the outer side. Belt locking pieces 12 each having a hole 12c, and a part of which is engaged with the groove 12a,
The springs 13 for urging the slide locking pieces 12 in the respective directions to be separated from each other, the bending pieces 14a abutting the outer surfaces of the bending pieces 10a of the substrate 10 on both side edges, and the rear ends of the slide locking pieces 12 are inserted. And a guide hole 14b that is
And a cover 14 that covers the upper part of 0. or,
The fitting 9 has a rear end portion 9b having a belt locking hole 9a.
And a locking projection 9d which is provided so as to project forward from both sides of the rear end 9b and has a locking claw 9c which is engageable with the engagement groove 11b of the slide locking piece 11 inward of the front end. ing.

When the locking projection 9d of the insertion fitting 9 is inserted between the base plate 10 and the cover 14 of the receiving fitting 8, the locking claw 9c formed on the locking projection 9d slides and locks. It abuts on the outside of the projecting piece 11a of the piece 11 and moves both slide locking pieces 11 inward against the elastic force of the spring 13. Then, when the locking projection piece 9d of the insertion fitting 9 is inserted to a predetermined position, the locking claw 9c causes the engagement groove 11 of the slide locking piece 11 to move.
Both slide locking pieces 11 are slid in a direction of being separated from each other by the elastic force of the spring 13 so that the locking claw 9c and the engaging groove 11b are engaged with each other. As a result, the receiving fitting 8 and the insertion fitting 9 are connected as shown in FIG. When both ends of the rear end portion of the slide locking piece 11 are pushed into the receiving metal fitting 8, the slide locking piece 11 slides inward, and the engagement between the locking claw 9c and the engagement groove 11b is released. as a result,
By pulling the insertion fitting 9 outward, the connection between the receiving fitting 8 and the insertion fitting 9 is released. In this latching metal fitting, a plate-like slide locking piece 11 is arranged in the receiving metal fitting 8 so as to be slidable in the horizontal direction.
Since it is configured to be operated from the side of the receiving metal fitting 8, the thickness of the metal fitting itself can be made extremely thin, and the slide locking piece 11 is extremely hard to receive an impact from the outside. It has excellent advantages such as preventing disengagement of the fitting 9.

[0005]

[Problems to be Solved by the Invention] However, there are still problems to be solved in the above-mentioned latching metal. That is, when the locking projection 9d of the insertion metal fitting 9 is inserted into the receiving metal fitting 8, the locking claw c of the locking projection 9d abuts the outside of the projection 11a of the slide locking piece 11, and both slide lockings are performed. The piece 11 is a spring 13
It is designed to move inward against the elastic force of. However, since the outside of the tip of the slide locking piece 11 is pushed by the locking claw 9c, the slide locking piece 11 tends to rotate in the direction of the arrow in FIG. 13 or to move inward while rotating.
As a result, the slide locking piece 11 may not move inward smoothly and smoothly when the insertion metal fitting 9 is inserted, and it can be said that the insertion metal fitting 9 cannot be inserted into the receiving metal fitting 8 smoothly and smoothly. There was a problem. If the slide locking piece 11 is first pushed into the receiving metal fitting 8 and then the inserting metal fitting 9 is inserted into the receiving metal fitting 8, the inserting metal fitting 9 can be smoothly inserted. Since the pushing operation of the piece 11 is required and the insertion fitting 9 cannot be inserted into the receiving fitting 8 with one touch, the operability is deteriorated. Further, since the hook-shaped locking claws 9c are provided on the insertion metal fitting 9, when the receiving metal fitting 8 and the insertion metal fitting 9 are disengaged, the locking nail 9c of the insertion metal fitting 9 is caught on clothes or the like. There was also a problem that some of the clothes would break.

The present invention was devised in order to solve the above problems, and the purpose thereof is to smoothly and smoothly insert the inserting tool into the receiving tool with one touch, and to connect the receiving tool and the inserting tool. An object of the present invention is to provide a hooking device that prevents the plugging device from being caught on clothes or the like when disengaged.

[0007]

In order to achieve the above-mentioned object, a hooking device of the present invention comprises a receiving member and an inserting member which is inserted into and locked by the receiving member. And the elastic member along the front-rear direction of the substrate having a locking protrusion and an operation protrusion formed on the upper surface of the substrate, the upper and lower portions of which are provided with a belt attachment portion and which are swingably and elastically deformable in the vertical direction in a substantially central portion of the substrate. A stop plate, a cover that is provided on the upper surface of the substrate and forms a space of a constant width between the substrate and the substrate, and the cover and the cover are disposed so as to be opposed to each other and to be horizontally slidable. The outer edge projects sideways from between the substrate and the cover,
When the outer edge is pushed inward, the inner edge rides on the operation protrusion and elastically deforms the elastic locking plate downward, and the pair of slide locking plates are separated from each other. And an elastic body that urges in the direction of It is composed of a plate-shaped insertion portion that elastically deforms the elastic locking plate downward when inserting it into the receiving member, and a belt attachment portion provided at the rear end portion of the insertion portion.

[0008]

When the insertion part of the insertion tool is inserted between the base plate and the cover of the reception tool, the elastic locking plate provided on the base plate is pushed downward by the insertion part and elastically deformed. When the insertion part is inserted to the predetermined position, the locking projection of the elastic locking plate and the locking hole of the insertion part face each other, the elastic locking plate returns to its original position by its elastic force, and the locking projection is It is engaged with the locking hole. As a result, the insertion tool is prevented from coming off the receiving tool, and the receiving tool and the insertion tool are connected. Further, when the outer edge of the slide locking plate of the receiver is pushed inward, the inner edge of the slide locking plate rides on the operation protrusion of the elastic locking plate,
Push the elastic locking plate downward. As a result, the elastic locking plate is elastically deformed downward, and the engagement between the locking protrusion and the locking hole is released. When the insertion tool is pulled in this state, the insertion tool comes out of the receiving tool, and the receiving tool and the insertion tool are disengaged. This latch has a structure in which an elastic locking plate that is vertically swingable and elastically deformable is provided on the base plate of the receiving tool, and the elastic locking plate is elastically deformed downward at the insertion portion of the insertion tool. ,
When the insertion tool is inserted into the receiving tool, the elastic locking plate elastically deforms smoothly downward. As a result, when the receiving device and the insertion device are connected, only by inserting the insertion portion into the receiving device, the insertion device is smoothly and smoothly inserted into the receiving device. As a result, the receiving member and the inserting member can be connected smoothly and smoothly with one touch. Moreover, since the insertion part of the insertion tool has a plate shape and only the engaging hole is formed in the insertion part, when the reception tool and the insertion tool are disengaged, the insertion tool is caught on clothes or the like. There is no saying.

[0009]

Further, as shown in FIGS. 4 and 5, on the upper surface of the elastic locking plate 3b, the locking projection 3i has an inclined surface which gradually increases as it goes to the free end side, and as the upper surface goes to both sides. The operation protrusions 3j each having an inclined surface which becomes lower gradually are integrally formed. The operation protrusion 3j is located closer to the free end than the locking protrusion 3i.

The cover 4 is made of a synthetic resin material, and as shown in FIG. 6, the top plate 4a disposed on the upper surface of the substrate 3 and the lower surface of the top plate 4a are connected to each other, and It is provided with a supporting leg 4b fitted in the T-shaped groove 3e. The cover 4 is attached to the upper surface of the substrate 3 with a certain space by fixing the support leg 4b to the groove 3e of the substrate 3 with an adhesive or the like. As a result, a space having a certain width is formed between the substrate 3 and the top plate 4a of the cover 4 into which the inserting tool 2 and the slide locking plate 5 described later are inserted.

The slide locking plate 5 is formed of a metal material into a substantially plate shape. The front end of the slide locking plate 5 is a projection 5a engageable with the projection 3d of the substrate 3, and the rear end of the belt mounting portion 3a. Protrusions 5b slidably engaged with the guide notches 3g are formed respectively. In addition, on the back surface of the central portion of the slide locking plate 5, a concave groove 5 slidably fitted in the protrusion 3c of the substrate 3 is formed.
At the rear end portion of the slide locking plate 5, there are formed fitting grooves 5d slidably fitted to the support legs 4b of the cover 4, respectively, to prevent the slide locking plate 5 from rattling. It is designed to do. Further, on the inner edge of the slide locking plate 5, there is formed a projection-shaped pressing portion 5e that presses the inclined surface of the operation projection 3j to elastically deform the elastic locking plate 3b downward. The slide locking plate 5 is horizontally opposed to and between the board 3 and the top plate 4a of the cover 4 so that the outer edge of the slide locking plate 5 projects laterally from between the board 3 and the cover 4. It is arranged slidably, and when the outer edge is pushed in, the pressing portion 5e rides on the inclined surface of the operation projection 3j and elastically deforms the elastic locking plate 3b downward. .

The elastic body 6 is interposed between the base plate 3 and the slide locking plate 5 and urges the two slide locking plates 5 in a direction to separate them from each other. In this embodiment, A coil spring is used for the elastic body 6.

And a belt mounting portion 2d integrally formed at the rear end portion of the insertion portion 2b and having a belt mounting hole 2c, and a rear end portion of the insertion portion 2b integrally formed with the receiving member 1 of the insertion portion 2b. And a stopper portion 2e that abuts against the cover 4 at the time of insertion and regulates the insertion depth of the insertion tool 2. The thickness of the insertion portion 2b is formed to be slightly smaller than the distance between the substrate 3 and the top plate 4a of the cover 4, and the insertion portion 2b is provided between the substrate 3 and the top plate 4a of the cover 4. When inserted in, the inclined surface of the locking projection 3i of the elastic locking plate 3b is pressed to elastically deform the elastic locking plate 3b downward.

Next, the operation of the latch will be described. In use, one end of a belt (not shown) is fixed to the belt mounting portion 3a of the receiving tool 1, and the other end of the belt is fixed to the belt mounting portion 2d of the insertion tool 2. When the insertion part 2b of the insertion tool 2 is inserted between the substrate 3 and the top plate 4a of the cover 4, the lower end of the insertion part 2b comes into contact with the inclined surface of the locking protrusion 3i of the elastic locking plate 3b to elastically lock. The plate 3b is pressed downward. As a result, the elastic locking plate 3b is elastically deformed downward, and the insertion portion 2b is smoothly and smoothly inserted into the receiving tool 1. When the insertion portion 2b is inserted to a predetermined position, the locking protrusion 3i and the locking hole 2
The elastic locking plate 3b is returned to the horizontal position by its elastic force, and the locking projection 3i is engaged with the locking hole 2a of the insertion portion 2b. As a result, the insertion tool 2 is prevented from coming off the receiving tool 1, and the receiving tool 1 and the insertion tool 2 are in a connected state (see FIGS. 8 and 9).

Push the free end of 3b downward. As a result, the elastic locking plate 3b is elastically deformed downward, and the engagement between the locking protrusion 3i and the locking hole 2a is released (see FIG. 11). When the insertion tool 2 is pulled in this state, the insertion tool 2 comes off the receiving tool 1, and the receiving tool 1 and the insertion tool 2 are in a dissociated state.

This hooking device has a structure in which when the insertion tool 2 is inserted into the receiving tool 1, the elastic locking plate 3b is elastically deformed downward by the insertion part 2b.
The insertion tool 2 can be smoothly and smoothly inserted into the receiving tool 1 without pushing. As a result, when the receiving tool 1 and the inserting tool 2 are connected, it is only necessary to insert the inserting portion 2b into the receiving tool 1, and the receiving tool 1 and the inserting tool 2 can be connected smoothly and smoothly with one touch. or,
Since the slide locking plate 5 projects from the side of the receiver 1, the slide locking plate 5 is extremely hard to receive an impact from the outside. As a result, when the hooking device is used, for example, to suspend ski pants, even if the skier falls over, the slide locking plate 5 is hardly affected by the frozen running surface, and the fall occurs. It is possible to prevent the receiving tool 1 and the inserting tool 2 from being dissociated from time to time. Further, the insertion portion 2b of the insertion tool 2 has a plate shape, and the insertion portion 2
Since only the locking hole 2a is formed in b, it cannot be said that the inserting tool 2 is caught on clothes or the like when the receiving tool 1 and the inserting tool 2 are disengaged. Moreover, since the upper surface of the substrate 3 is covered with the cover 4, the surface of the receiving tool 1 can be wide. As a result, a pattern can be formed on the surface of the receiving tool 1, and effective utilization can be achieved.

In the above embodiment, the substrate 3, the belt mounting portion 3a, the elastic locking plate 3b, the cover 4 and the insert 2 are each made of a synthetic resin material, and the slide locking plate 5 is made of a metal material. However, in other embodiments, all members may be made of synthetic resin material, or all members may be made of metal material.

In the above embodiment, the substrate 3 and the cover 4
However, in another embodiment, the substrate 3 and the cover 4 may be integrally formed.

In the above-mentioned embodiment, the base plate 3 and the elastic locking plate 3b are integrally formed, but in other embodiments, the base plate 3 and the elastic locking plate 3b are formed separately and the base plate 3 and the elastic locking plate 3b are elastically engaged. The stop plate 3b may be attached so as to be vertically swingable and elastically deformable.

In the above-described embodiment, the free end of the elastic locking plate 3b is directed toward the rear of the substrate 3. In other embodiments, the free end of the elastic locking plate 3b is used. May face the front of the substrate 3. In this case, it is necessary to reverse the positions of the locking projection 3i and the operation projection 3j.

In the above embodiment, the elastic body 6 is attached to the substrate 3
Although it is interposed between the slide locking plate 5 and the slide locking plate 5, in another embodiment, the elastic body 6 is interposed between the cover 4 and the slide locking plate 5 or between the slide locking plates 5. You may do it.

[0024]
