In addition, if some of the teeth are missing, the slider will not move and the fastener pieces cannot be connected and separated.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to operate a slider by catching a cloth like a conventional fastener or by missing a coupling tooth.
It prevents the user from being able to move the clothes, which prevents the opening of clothing and other items from being opened and closed.
It is an object of the present invention to provide a fastener that can prevent an opening of clothing or the like from being left open even if the user forgets to close it.

[0004]

In order to solve this problem, the first means adopted by the present invention is to provide a fitting protrusion having a hook-like tip on the inner surface in the longitudinal direction. In addition, a fitted portion is provided on the outer side surface, and a first fastener piece attached to one end edge of each of the fabrics, and a fitting protrusion of the first fastener piece on the inner side surface. And a second fastener piece attached to the other end edge of each of the fabrics, the fitting groove being provided continuously in the lengthwise direction, and the fitted portion being provided on the outer surface thereof. , The two fastener pieces are sandwiched from both sides in a state where the fitting ridges of the first fastener piece are fitted in the fitting grooves of the second fastener piece, and each fitted part A fitting part that is slidably fitted to the main body plate is provided at one end in the sliding direction of the body plate, A fastener is constituted by a slider provided on the other end of the main body plate in the sliding direction for separating both fastener pieces, and each of the first and second fastener pieces is Is also made of a flexible material such as resin, and the slider is slid in one direction, and the fitting protrusion of the first fastener piece causes the fitting ridge of the second fastener piece to slide. The sliders are slid in the other direction so that the sliders are slid in the other direction so that the first fastener piece and the first fastener piece are fitted into the fitting grooves. This is a structure in which the articles are sequentially removed and the two are separated.
In addition, in order to solve the above problems, the second aspect of the present invention is adopted.
The means is to shape and magnetize each of the first and second fastener pieces constituting the fastener by a flexible material impregnated with magnetic powder.

[0005]

When the slider is moved in the direction in which the fastener pieces are connected to each other, the fastener pieces are sandwiched from both sides by the fitting portions provided on the slider.
The fitting ridges of the first fastener piece are successively fitted and fitted into the fitting grooves of the fastener pieces, thereby connecting the fastener pieces. Further, when the slider is slid in the opposite direction to the above, the separation protrusion provided on the slider causes the fitting protrusion of the first fastener piece fitted in the fitting groove of the second fastener piece. , And the fastener pieces in the connected state are sequentially separated. Here, since the tip end portion of the fitting projection provided inside the first fastener piece is formed in a hook shape, the fastener pieces should be separated in the connected state of the fastener pieces. Even if a lateral force is applied, the respective fastener pieces are not separated because the tips of the fitting projections of the first fastener pieces are caught by the second fastener pieces. Further, the fastener according to the present invention
Since the fastener piece of is not provided with any portion for engaging the cloth like the coupling teeth of the conventional fastener piece,
The problem that the slider does not move and the opening of clothing or the like cannot be opened or closed does not occur. Further, when each fastener piece is molded and magnetized with a flexible material impregnated with magnetic powder, the connecting force of each fastener piece at the time of connection is further increased, and each fastener piece is connected. Even when the opening of clothes or the like is opened by unfastening, the fastener pieces are connected by the magnetic force, and the opening does not open greatly.
