Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a locking mechanism for a goby in a cover that uses a goby, such as an underground tab.

``Conventional Technology'' Underground tabiyatabi are worn by attaching a kohaze from the ankle to the calf, which is secured to a hanging thread. When locked in this manner, it is possible to adjust the thickness of the area from the ankle to the calf of the wearer, and has the feature of providing a tight feeling to this area.

However, even if it is hung as described above,
When used for work such as underground fishing, the kohaze often comes off when the appropriate tension is momentarily lost between the kohaze and the hanging thread, or when the legs are bent. If the kohaze comes off like this while wearing the shoes, it will give a sense of anxiety to workers who are working at heights, and this is not desirable. Also, even in general, when the dancer makes violent movements, the kohaze may come off, so it is desirable to securely lock the kohaze.

Furthermore, recently, from the viewpoint that it is troublesome to put on and take off a large number of shoes one by one, we have installed a fastening device such as a snap, a chuck, or a flat fastener in addition to the stopper locking part, and once it is adjusted to the size of the foot. A one-touch method has been proposed in which the latched goby is removed underground by simply opening and closing the locking tool without removing it. However, the goby in such underground places,
It would be better if it would not come off even when the legs are removed, and conventional locking mechanisms have not been able to achieve this purpose.

``Problems to be Solved by the Invention'' In view of the above-mentioned drawbacks, the present invention aims to provide a locking mechanism that can reliably lock a goby by hooking it onto a hanging line. In order to achieve this purpose, the present inventor has proposed a locking mechanism that incorporates a snap-type concave-convex fitting mechanism into the kohaze and can reliably hook the hanging thread (Japanese Patent Application No. 61-237468). (Japanese Patent Publication No. 3-37402), the present invention is capable of locking in the same way as the above proposal, and is intended to simplify the mechanism and improve operability.

``Means for Solving the Problems'' That is, the first aspect of the present invention is that in a locking mechanism for locking a locking goby to a hanging thread, the locking mechanism is configured such that the locking goby is composed of a set of two thin pieces, and the root The sides are integrally formed, the tip side is open, and at least one of the thin pieces has an outwardly convex protuberance into which the thread is inserted,
In addition, the second invention is a locking mechanism for locking a goby on a hanging line, in which the locking goby is composed of a set of two thin pieces, the base side of which is integrally formed, and the tip side of the locking mechanism. It has a structure that exhibits elasticity so that it opens but normally closes on the tip side, and is characterized in that at least one of the thin pieces has an outwardly convex protuberance into which the thread is inserted. .

The present invention will be explained below based on the drawings, and FIG. 1 is a perspective view of an underground building equipped with the locking mechanism of the present invention;
Fig. 2 is a perspective view of the crow in the first invention, Figs. 3 A and B are a perspective view and a plan view of the crow in the second invention, and Fig. 4 is the locking state when it is locked. FIG.

In the figure, 1 is the top of the underground tab, 2 is the ground bottom, 3 is the kohaze, 4 is the hanging thread, 1A is the outer fabric,
1B is the lining fabric. Further, 3A is one of the thin pieces constituting the kohaze, 3B is the other thin piece, 3C is a raised portion provided on one of the thin pieces 3A, and 3D is a suture hole.
This kohaze 3 is composed of a set of two thin pieces 3A and 3B, but the base side is integrated, the tip side is open so that the hanging thread 4 can be inserted, and at least one of the thin pieces 3A and 3B is In the figure, one thin piece 3A
An outwardly projecting protuberance 3C is provided on the periphery. Note that this kohaze 3 is made of metal or the like as in the past, but in the case of the first invention, the two thin pieces 3A and 3B may be connected at the base side, or separate pieces may be integrated at the same time as suturing. It's okay. In the case of the second invention, as shown in FIG. 3, the base sides of the two thin pieces 3A and 3B are integrally and thickly bent, so that the tips are normally closed. It has a structure that exhibits elasticity.

When putting on the shoes, they are first put on in the same way as regular underground shoes, and the kohaze 3 is hung on a thread 4 whose thickness corresponds to the thickness of the wearer's ankle to calf region. At this time, insert only one thin piece 3A that makes up the Kohaze 3 while passing through the hanging thread 4, so that the hanging thread 4 is inserted into the raised part 3.
Make it fit into C. This results in two flakes 3
A and 3B are in a position to hold the hanging thread 4, but when the shoe is worn, force is applied from the inside to the outside (arrow in Fig. 4), so the protrusion 3C is pushed and the hook is further tightened. Stopping is ensured. When taking off the basement tab, remove the thread 4 from the raised part 3C by removing the thin pieces 3A and 3B.
All you have to do is remove Kohaze 3 while opening it.

In particular, the second invention of the present invention is designed to exhibit elasticity in the two-layered kohaze, so that it can be held onto the hanging thread with elasticity, so that feet can be removed from underground spaces etc. It does not come off even when pulled out, and is therefore particularly excellent as the one-touch locking mechanism described above. As for the size of the raised portion 3C, the width W is slightly larger than the thickness of the hanging thread 4, the height H may be about the thickness of the hanging thread 4 or slightly smaller than this, and it extends long as shown in the figure.

The locking mechanism of the present invention may be applied to all of the gobies as shown in the figure, or may be applied to only some of them. Further, the raised portion 3C may also be provided on the other thin piece 3B, or may be provided on both 3A and 3B. At this time, the length of one of the thin pieces 3A may be made slightly longer than the other thin piece 3B.

"Effects of the Invention" Since the present invention is constructed as described above, there is an advantage that the two-layered kohaze can be securely latched to the hanging thread, giving the wearer a sense of security. In addition, it is particularly excellent as the one-touch locking mechanism described above.
