[Industrial application field]

This invention is a push-pull device that can be attached to clothing belts, pants hanging bands, etc. Concerning improvements to mold latches.

0002

[Conventional technology]

In recent years, it has been used as a fastener for clothing belts, pants hanging bands, etc. Attach the bracket and the insertion bracket to both ends, and connect or connect the bracket and the insertion bracket with one touch. So-called push-type latches that can be released are widely used. Conventionally, this type of latching metal fitting is disclosed in, for example, Japanese Utility Model Application Publication No. 2-54407. A type of structure is known, which consists of a receiving fitting 13 and an insertion fitting 14. has been done. Specifically, as shown in FIG. Between the guide body 15, which has supporting pieces 15c protruding from both sides of the guide body 15b, and the supporting pieces 15c, A presser is arranged to be swingable and has a presser piece 16a at its tip that protrudes toward the bottom plate 15b. The presser body 16 is interposed between the guide body 15 and the presser body 16, and the rear end of the presser body 16 is An elastic body 17 biases the guide body 15 in a direction away from the guide body 15. Further, the insertion fitting 14 is formed into a plate shape as shown in FIG. It has a locking piece 14a that can be freely locked in the matching hole 15a, and the tip side is connected to the guide body 15 and the presser body. It can be inserted between 16 and 16. Then, the tip of the insertion fitting 14 is connected to the guide body 15 of the receiving fitting 13 and the presser body 16. When inserted between the two, the tip of the presser body 16 is elasticized by the latch piece 14a of the insertion fitting 14. It is pushed up against the elastic force of the body 17, and the insertion fitting 14 is successively inserted into the receiving fitting 13. I'm going to get lost. When the insertion fitting 14 is inserted to the predetermined position, the latch piece 14a is attached to the guide body 15. While being locked in the engaging hole 15a, the presser body 16 is returned to its original position by the elastic force of the elastic body 17. The insertion fitting 14 is returned to the position shown in FIG. That is, the receiving fitting 13 and the insertion fitting 14 are connected (see FIG. 15). On the other hand, push down the rear end of the presser body 16 and insert the insertion fitting 14 into the bottom plate 1 of the guide body 15. 5b, the lock between the locking piece 14a and the locking hole 15a will be released. As a result, the receiving fitting 13 and the insertion fitting 14 are separated (see FIG. 16).

0003

[Problem that the idea aims to solve]

However, in the conventional latch fitting, the movable part, that is, the presser body 16 is used as a guide. It is formed to be approximately the same size as the body 15, and is shaped to approximately cover the guide body 15. The presser body 16 has a structure that is extremely susceptible to external shocks. For that reason, hanging If the fastener is used to hang ski pants, for example, the skier may fall. When it is knocked down, the presser foot 16 is surely impacted by the frozen sliding surface and swings. Something happened. As a result, the pressure on the insertion fitting 14 is removed, and it engages with the latch piece 14a. The locking with the hole 15a comes off, and the receiving fitting 13 and the insertion fitting 14 easily separate. There was a problem. In addition, when the insertion fitting 14 receives external force, the insertion fitting 14 is pushed against the tip end side of the presser body 16. In some cases, the guide body 15 was pushed up and lifted off the bottom plate 15b of the guide body 15. As a result, even if the insertion fitting 14 is subjected to external force, the engagement between the locking piece 14a and the locking hole 15a remains constant. There were times when the stop would come off. Furthermore, since the hooking piece 14a is provided protruding from the insertion fitting 14, the receiving fitting 13 and the insertion fitting 14, the hooking piece 14a of the insertion fitting 14 gets caught on the clothes, causing the clothes to become loose. There were times when the department would fall apart.

0004 This invention was created to solve the above problems, and its purpose is A latch that prevents the receiver and the insert from coming apart easily even if a shock is applied from the outside. To provide fittings.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the string stopper of the present invention has a guide hole formed at approximately the center position. An insert is inserted between the cover body and the cover body on the back side of the cover body. It is installed to create a space and has mounting holes for attaching belts and bands. It is attached to the top surface of the tip of the main body so that it can swing freely in the vertical direction, and projects upward. A locking plate is provided with a locking protrusion to be installed, and a locking plate is interposed between the main body and the locking plate to prevent play of the locking plate. An elastic body that urges the end upwards and an elastic body that is inserted into the guide hole so that it can move up and down and come into contact with the locking plate. A retaining body that contacts the retaining plate and swings the locking plate downward against the urging force of the elastic body. A locking hole that can be freely locked to the locking protrusion of the locking plate at the tip, and a belt or other hole at the rear end. Each has mounting holes for attaching the band, and the tip side is connected to the cover body and the locking plate.

[0006]

[Effect]

When the insert tool is inserted between the cover body and the locking plate from 0000, the insert tool will The locking plate is pushed down against the elastic force of the elastic body, and the insert is inserted into the receiver. They are inserted one after another. When the insert is inserted into the specified position, the locking plate is lifted up by the elastic force of the elastic body. At the same time, the locking protrusion locks into the locking hole of the insert. As a result, The fitting and the insert are in a connected state. Then, when the presser body is pushed into the cover body, the locking plate is pressed against the elastic body by the presser body. It is pushed downward against the elastic force, and the locking protrusion and the locking hole are disengaged. this If you pull the insert in this state, the insert will come out of the receiver and the receiver and insert will be separated. becomes dissociated. This latch tool allows you to move the presser body up and down through a guide hole formed at approximately the center of the cover body. Insert the tool freely, and push the locking plate's locking protrusion into place by pressing the presser foot. Since the presser foot is removed from the locking hole, the presser foot is extremely difficult to receive external shocks. It has become. As a result, the latches can be used, for example, to hang ski pants. If the skier falls, the presser foot may be impacted by the iced running surface. There is almost no chance of the product falling off, and it prevents the receiver and the insert from coming apart in the event of a fall. Ru. Also, a locking protrusion that locks into the locking hole of the insert is attached to the locking plate that is biased toward the cover body side. , and the insert is inserted between the cover body and the locking plate, so it is not possible to temporarily insert it. Even if the tool receives external force and tries to move toward the cover body or the main body, the insert tool will not move. The locking plate always comes into contact with the elastic force of the elastic body. As a result, the spigot The locking protrusion will be securely locked in the locking hole, and an external force will be applied to the temporary insert. Even if the locking protrusion and the locking hole are disengaged, there is no possibility that the locking protrusion and the locking hole will become disengaged. Furthermore, the insert has a plate shape and only has a locking hole and a mounting hole. Therefore, if the insert gets caught on clothes etc. when the receiver and insert are separated, There's nothing to say.

As a result, the latching device can be When used to hang key pants, even if a skier falls down, the presser foot will not work. There is almost no chance that the body 7 receives any impact from the frozen sliding surface, and when falling, It is possible to prevent the receiving tool 1 and the inserting tool 2 from disassociating. However, this latching tool has a latching protrusion 5 at the base end of a latching plate 5 that can freely swing in the vertical direction. a, and press the free end of the locking plate 5 with the presser body 7 to push the locking protrusion 5a into the locking hole 2a. Since the presser foot 7 must be pushed far into the cover body 3, it will not engage. The locking protrusion 5a is prevented from completely coming out of the locking hole 2a. As a result, tentatively Even if the presser foot 7 receives an impact and is pushed in a little, the locking protrusion 5a will not move from the locking hole 2a. It does not come off completely and further prevents separation of the receiver 1 and the insert 2. can. In addition, the locking plate 5 is biased toward the cover body 3 and is locked in the locking hole 2a of the insert 2. A locking protrusion 5a is formed, and an insert 2 is inserted between the cover body 3 and the locking plate 5. Therefore, the temporary insertion tool 2 receives external force and is displaced toward the cover body 3 or the main body 4. Even if you try to do so, the locking plate 5 always comes into contact with the insert 2 due to the elastic force of the elastic body 6. That will happen. As a result, the locking protrusion 5a is securely locked in the locking hole 2a of the insert 2. Therefore, even if the temporary insertion tool 2 receives external force, the locking protrusion 5a and the locking hole 2 There is no possibility that the lock with a will come off. Further, the insert 2 has a plate shape and has a locking hole 2a and a mounting hole 2b. When the receiver 1 and the insert 2 are separated, the insert 2 is There is no chance that it will get caught on clothes, etc.

Insert the presser foot so that it can move up and down, and press and operate the presser foot to engage the Since the locking protrusion of the stop plate is removed from the locking hole of the insert, there is no possibility that the presser body is outside. It has become extremely difficult to receive shocks from these forces. As a result, the latching device can be attached to a ski pad, for example. When used to hang pants, the presser foot will not freeze even if a skier falls. There is almost no impact from the sliding surface, and there is no difference from the impact receiving device. It can prevent disassociation of the fittings. In addition, the latching tool is latched into the latching hole of the insertion tool by the latching plate that is biased toward the cover body. A locking protrusion is formed, and an insert is inserted between the cover body and the locking plate. Because the temporary insertion tool receives external force and tries to displace toward the cover body or the main body side. However, the locking plate will always come into contact with the insert due to the elastic force of the elastic body. . As a result, even if the insert is subjected to external force, the locking protrusion is securely locked in the locking hole. This prevents the locking protrusion from coming off the locking hole. Furthermore, the insert has a plate shape and only has a locking hole and a mounting hole. Therefore, if the insert gets caught on clothes etc. when the receiver and insert are separated, There's nothing to say.
