Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separable bottom end stop which is attached to the end portions of both left and right fastener stringers constituting a slide fastener to completely separate and join the left and right fastener stringers.

[0002]

2. Description of the Related Art A commonly used separable bottom end stop has a box body with a box rod to be attached to the end portion of one fastener stringer, and an insert pin to be attached to the end portion of the other fastener stringer. When connecting both separated fastener stringers, keep the slider in contact with the box, insert the insert pin deeply into the box through the slider, and keep the inserted state. Is to slide upward, and at that time hold the connected state of the box body and the insert pin combined with this with one hand,
It is necessary to slide the slider with the other hand. Also, when separating the two fastener stringers that are joined, the slider is pulled out while holding the slider in contact with the box, so hold the slider and box together with one hand. However, it is necessary to remove the insert pin from the box with the other hand, and it is difficult for an infant, a handicapped elderly person or a physically handicapped person to operate with both hands.

As a means for solving the above problems, for example, the one described in Japanese Utility Model Publication No. 45-7845 is known. The publication discloses a means for fixing the slider and the box body, and one example of the means is to provide a tab on the pull tab and to provide a hole in the box body. The groove of the body is formed in a straight line.

[0004]

According to the means described in the above publication, the slider and the box body can be integrally fixed, and the insert pin can be inserted with one hand. However, after inserting the insert pin, slide the slider up to close the slide fastener, but when the slider slides at the start, the insert pin is also lifted together with the slider and pulled out from the box. Is probably there.
Especially in the case of a jumper or the like, since the pulling force acts on the insert pin and the box body in a direction in which they are separated from each other, the insert pin inserted at the time of starting the slider may come out and cannot be closed.

Therefore, according to the present invention, the slider and the box body are integrally fixed as described above so that the insert pin can be inserted with one hand, and the fastener stringer is a counterpart of the insert pin when the slider is started. It is engaged with the first engaging tooth of the cleats, prevents the insert pin from floating, and can securely connect both fastener stringers with one hand. Moreover, when separating, the engaging relation between the insert pin and the mating first insert tooth An object of the present invention is to provide a separable bottom end stop of a slide fastener that can be released and can be normally joined and separated with a single hand with a fastener stringer.

[0006]

According to a solution of the present invention, a box body is formed by an outer box with a box rod and an inner box, and the inner box is biased by a spring so as to project above the outer box. It is provided with a hollow portion into which the insert pin is inserted between the inner box and the box rod, and further, a locking portion is provided on the outer surface of the box body, and the inner box is pushed down by a slider against the spring. The slider is provided at a position where the pull tab of the slider engages, and on the other hand, the insert pin is provided with an engaging projection portion that meshes with the first engaging tooth of the partner.

[0007]

When the slide fastener having the separable bottom end stop according to the present invention is joined from the separated state, the slider puller is locked against the outer box while pressing the slider against the inner box against its spring. The hook is inserted into the hollow part through the slider, and then the pull tab is released from the locking part.When released, the pressure on the spring is released, and the inner box rises due to the repulsive force of the spring. As a result, the insert pin is pushed closer to the box pin side as it is raised, and the posture of the insert pin is adjusted in parallel so that the engaging protrusion of the insert pin meshes with the mating first engaging tooth. Since the slider slides under the above conditions, the insert pin can be securely closed without coming off. On the other hand, when separating from the combined state, it is sufficient to press the inner box with the slider and then hook the pull tab on the locking part as in the above, and then pull out the insert pin from the inner box. When hooked, the engaging protrusion of the insert pin is inclined so as to be disengaged from the first engagement tooth, so that the taking-out operation is facilitated.
