JPH01104802A - Engaging mechanism of clasp - Google Patents

Abstract

PURPOSE: To provide the subject engaging mechanism, capable of surely engaging clasps according to simple operations and imparting a sense of security to a wearer without disengaging the clasps and useful for split-toed heavy-cloth shoes, etc., by fixing an engaging tongue piece capable of fitting onto a hooking thread to be nipped thereby and made of an elastic material on the inner surface of each clasp. CONSTITUTION: This engaging mechanism for clasps is obtained by fixing an engaging tongue piece 3A, capable of fitting onto a hooking thread 4 and nipping the hooking thread 4 and made of an elastic material to the inner surface of each clasp 3 and hooking the clasps 3 on the hooking thread 4 according to the thickness ranging from an ankle to the sural part of a wearer and fitting the engaging tongue piece 3A on the inner surface of each clasp 3 onto the hooking thread 4 made of the elastic material, nipping the hooking thread 4 and surely engaging the clasp 3 with the hooking thread 4 at the time of wearing in the engaging mechanism for the clasps 3 capable of engaging the clasps 3 fixed to a part ranging from the ankle to the sural part of split-toed heavy-cloth shoes 1 with the hooking thread 4.

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 is possible to adjust the thickness of the area from the ankle to the calf of the wearer and provide a tightening window for this area.

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, the kohaze may come off due to violent movements during dance, so it is desirable to securely lock the kohaze.

Furthermore, recently, from the viewpoint that it is troublesome 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 tool without removing it. However, it is good for small gobies that live underground like this to stay in place even when their legs are removed.
Conventional locking mechanisms have not been able to achieve this objective.

``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 objective, the present applicant has proposed a locking mechanism that incorporates a snap-type concave-convex fitting mechanism into the kohaze and can securely lock the hanging thread (Japanese Patent Application No. 61-237468). No.) The present invention is of the same kind as the above proposal, and further relates to a locking mechanism that is simple and has a high operability.
I.

``Means for Solving the Problems'' That is, the present invention provides a locking mechanism for locking a goby to a hanging thread, the inner surface of the goby is made of an elastic material, and is inserted into the hanging thread and clamped. It is characterized by having a locking tongue piece that can be fixed.

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, and Fig. 3 is a perspective view of the locking mechanism of the present invention. It is a sectional view of a stop part.

In the figure, 1 is the underground upper, 2 is the ground bottom, 3 is the bottom, 4 is the hanging thread, IA is the outer fabric, and 1B is the lining fabric. Further, 3A is a locking tongue piece made of an elastic material, which can be fitted onto and clamped onto the hook. Note that this locking tongue piece 3A is fixed to the inner surface of the goby 3 as shown in the figure.
It is not limited to the wire rod shown in the figure, but may also be manufactured using spring pieces.

When hiring, first the wearer wears it in the same way as a regular underground wearer, and the kohaze 3 is hung on a hanging thread 4 whose thickness corresponds to the thickness from the ankle to the calf of the wearer. At this time, the locking tongue piece 3A on the inner surface of the goby 3 fits into the hanging thread 4 in response to the hanging of the goby, but since the locking tongue piece 3A is made of an elastic material, the hanging thread 4 is held between the locking tongue pieces 3A. Since the thread 4 and the thread 3 are tied together, the thread 4 and the thread 3 are very securely engaged.

On the other hand, when the goby 3 is to be removed, it can be done without difficulty due to the elasticity of the locking tongue 3A.

The locking mechanism of the present invention may be applied to all the kogozes,
Also, it may be applied only to a part.

``Effects of the Invention'' Since the present invention is as described above, the presence of the unique locking tongue makes it possible to more securely lock the hanging line of the goby.
However, it has the advantage of being easy to operate and giving the wearer a sense of security. Moreover, it is particularly excellent as the one-touch locking mechanism described above.
