Description

  The present invention relates to a locking spring provided in a locking recess of a female hook among a pair of female and male hooks used to lock an opening of clothes, bags, bags, etc. It is related with the improvement of the male hook to be caught and locked.

  2. Description of the Related Art Conventionally, as a means for attaching a male hook to clothes or the like, a method using a stopper member having a pipe-like caulking leg that is widened and stopped by a tip is widely known (see Patent Document 1).

  However, the pipe-type caulking leg in the conventional system has a relatively large diameter because of the necessity of obtaining sufficient strength and the necessity of expanding and crushing the tip thereof. For this reason, it was necessary to open a pilot hole in the attachment part of clothes, etc., the problem that the installation process for opening the pilot hole was cumbersome, resulting in a decrease in production efficiency, an increase in cost, and the like. The stopper member with a watermark pattern has a thick pipe-like caulking leg and its wall thickness (thickness) is thin, so that the pipe-like caulking leg is exposed through the watermark hole. There was a problem that it was difficult or impossible to carry out due to reasons such as loss of appearance.

In addition, in the caulking operation of the caulking leg, a problem is that a large force is required to extend and expand the tip opening edge of the caulking leg, and for this reason, the hook body and its decorative part are often used. If damage or deformation is likely to occur, or if the damage or deformation occurs during attachment to clothes or other clothing, it can hardly be removed and reattached, resulting in the disposal of the clothing and other clothing. There was a problem of inviting a situation that could not be obtained.
