[Detailed description of the invention]

[0001]

[Industrial application] This invention is based on the idea of using a box pin, a butterfly pin, or the like at one end of a fastener chain in a hidden slide fastener.
The box and mounting only, based on the opening and closing operation of the slider, releasing open the fastener chain in the closing state to the left and right stringers, also includes a function to close the fastener chain of the open state, and the box is a slider The present invention relates to a hidden slide fastener provided with a separable bottom end stop having a mechanism capable of holding the engagement of the slide fastener.

[0002]

2. Description of the Related Art Conventionally, a separable bottom end stop, which is known as a separable bottom end stop of a concealed slide fastener , is formed by integrally forming a step-like projection, which is a stringer mounting portion corresponding to a box pin, and a box body. 2. Description of the Related Art There has been known a separable insertion fastener (see Japanese Utility Model Publication No. 38-7939) of a concealed slide fastener constituted by a box formed by means and a butterfly pin.

Further, a mounting portion corresponding to a box bar and a box body are formed by integral molding means , and the mounting portion is centered on the mounting portion.
A vertical wall surface is provided upright on the back surface and one side surface of the top surface of the box body around the opening, and a hidden slide fastener formed so that a slider can be inserted between the wall surface and the mounting portion. A fitting insert (see Japanese Utility Model Publication No. 51-4816) is known.

[0004]

First known example mentioned in the previous section - devised is to solve the above is no <br/> association without the box body and the slider in the separable bottom end stop, the insert pin attached to the stringers When inserting into the box, in the state where the slider and the box are joined,
Very unstable, that plugged securely to the box insert pin is there is such a problem is the affliction.

In the case of the second known example, the joint between the slider and the box is stable , but the size of the box must be larger than that of a normal box.
In prayer, when sewing the results concealed slide fastener to the kimono, sewing remove the box body from the fastener chain
Since it is not possible to Seisuru, can not appropriate sewing a box body is disturbed, appearance also had such problems often stomach.

[0006] This invention aims to solve the above-mentioned problems.
The inset fitting used in the concealed slide fastener of the present invention keeps the box and the slider in a stable joint state, and the operation of inserting and detaching the wingpin from the box can be performed smoothly. And the box body and the box stick are formed separately, and the box body is
Configured so that it can be retrofitted, when sewing the stringers to deposits, not a box body disturbed, it is possible to clean sewing, moreover generated by push-up force from the rear surface of the separable bottom end stop An object of the present invention is to provide a hidden slide fastener equipped with a separable bottom end stop which can prevent a chain cracking phenomenon.
