Abstract

PURPOSE: To surely lock a clasp through a hook thread by composing the clasp of a main clasp piece and a subordinate clasp piece positioned inside, the top end parts of both the clasp pieces, shortening the subordinate clasp piece rather than the main claps piece and making their rear ends a little higher. CONSTITUTION: A clasp 3 is composed of a main clasp piece 3A and a subordinate clasp piece 3B, the top end parts of both the clasp pieces are fixed, the subordinate clasp piece 3B is made shorter than the main clasp piece 3A, and their rear ends are made a little higher so that elasticity can be applied in the direction of the main clasp piece 3A. Therefore, an elastic element 5 such as sponge for applying elasticity on the subordinate clasp piece 3B is arranged. This clasp composed of two pieces can be surely locked through the hook thread especially because of its subordinate clasp piece, and easiness can be applied to a wearing person.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a locking mechanism for footwear used in footwear such as underground footwear.

``Conventional Technology'' Underground tabiyatabi are worn by attaching a kohaze from the ankle to the calf and hooking it to a hanging thread. When locked in this manner, it can be adjusted according to the thickness of the wearer's ankle to calf region, and has the feature of providing a tight feeling to the core region.

However, even if it is hung as described above, when used for work such as underground fishing, the appropriate tension between the kohaze and the hanging line may be momentarily lost, or the legs may be bent. The goby often comes off. If the kohaze comes off while wearing the shoes, it will give a sense of anxiety to workers who are working at heights, and this is not desirable. In addition, 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 cumbersome to attach and remove a large number of kohaze one by one, a locking device such as a snap, a zipper, or a hook-and-loop fastener is installed in addition to the kohaze locking part.
A one-touch method has been proposed in which the goby, which has been locked according to the size of the foot, is opened and closed by simply opening and closing the locking device without removing it. However, it is preferable for the goby in such underground locations to not come off even when the legs are removed, and the conventional goby locking mechanism has not been able to achieve this purpose.

``Problems to be Solved by the Invention'' In view of the above-mentioned drawbacks, the present invention incorporates a locking mechanism that can hook and reliably lock the goby on the hanging line, and incorporates a locking mechanism that can securely lock the goby on the hanging line. A locking mechanism has been proposed (Japanese Patent Application No. 61-237468), but the present invention is capable of locking in the same manner as that proposal, and is intended to simplify the mechanism and improve operability.

``Means for Solving Problems'' In other words, the present invention ≠ Chugin's mission is that in a locking mechanism for locking a locking goby to a hanging thread, the locking mechanism for locking a locking goby is a main locking goby piece and a secondary locking piece located inside the main locking goby piece. The tips of both the comb pieces are fixed together, the auxiliary comb piece is made shorter than the main comb piece, and the rear end is slightly higher to exhibit elasticity in the direction of one of the main comb pieces. It is characterized by:

The present invention will be explained below with reference to the drawings. 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 a coby used in the present invention seen from the front side, and Fig. 3 FIG. 4 is a side view, and FIG. 5 is a perspective view showing a state in which a goby is caught on a hook.

In the figure, ■ is the upper part of the basement, 2 is the ground bottom, 3 is the kohaze, and 4 is the hanging line. It consists of The secondary kogoe piece 3B is shorter than the main kogoe piece 3A, and its rear end is slightly higher than the main kogoe piece 3B.
It is designed to exhibit elasticity in the B direction. 5 in the diagram
is an elastic piece such as a sponge that gives elasticity to the sub-coby piece 3B.

When putting on the shoes, the shoes are first put on in the same way as regular underground shoes, and the kohaze 3 is hooked onto a thread 4 whose thickness corresponds to the thickness from the ankle to the calf of the wearer. At this time, when inserting the thread 3 into the hanging thread 4, the secondary thread piece 3B comes close to the main thread piece 3A due to its elasticity, and it can be inserted without any resistance, but after this, the secondary thread 4 The rear end of the small piece 3B is caught and securely locked (see Fig. 5).

When taking off the basement tab, sub-kohaze 3B from the upper 1 side.
It can be removed by pulling out Kohaze 3 while pressing down.

In particular, the present invention is securely locked by the rear end of the auxiliary goby 3B, so even when the foot is removed from a sheet metal basement door, etc., the foot does not come off. Therefore, it is particularly excellent as the above-mentioned one-touch type goby locking mechanism. There is.

In the illustrated example, the locking mechanism of the present invention is applied to all the gobys, but it may be applied only to some.

"Effects of the Invention" Since the present invention is as described above, it has the advantage that the two-piece kohaze, especially the secondary kohaze piece, can be securely latched to the hanging thread, giving the wearer a sense of security. be. Moreover, it is particularly excellent as the one-touch locking mechanism described above.

[Brief explanation of the drawing]

Fig. 1 is a perspective view of an underground case showing an example of applying the locking mechanism of the present invention, Fig. 2 is a perspective view of the kohaze used in the present invention as seen from the front side, and Fig. 3 is a perspective view of the same as seen from the inside. FIG. 4 is a side view, and FIG. 5 is a perspective view showing a state in which the goby is caught on the hanging line. Piece 4 indicates a hanging thread, and 5 indicates an elastic piece.゛Goni-no

Claims (1)

[Claims] In the locking mechanism of the coffin that locks the coffin to the hanging thread, the coffin is composed of a main coffin piece and a secondary coffin piece located inside this, and the tips of both coffin pieces are fixed, and the secondary coffin piece A locking mechanism for a coffin, which is characterized in that the main coffin piece is made shorter than the main coffin piece, and the rear end is made slightly higher so that the main coffin piece exhibits elasticity in one direction.
