Separable fitting for slide fastener

Abstract

The present invention provides a separable fitting (1) in which a box pin (20, 20') has a box pin body (21, 21'), a first cutout (23, 23') for receiving the head end of a locking pawl (36) of a reverse opening slider (30), and a projection (24, 24') projecting toward an insert pin (10) in the direction of the tape width from a surface (26) opposed to the insert pin (10). A side wall surface (23b) of the first cutout (23, 23') and that end surface (24a) of the projection (24, 24') which is provided to the head end side of the box pin are formed flush with each other to form a locking surface (27) with which the head end of the locking pawl (36) makes contact to lock the reverse opening slider (30). The box pin body (21, 21') and the projection (24, 24') have a slope surface (28, 28') declined from the position of the locking surface (27) toward an element row (5). The construction enhances easiness of operation of the reverse opening slider (30) and reliably prevents the reverse opening slider (30) from freely sliding from the box pin-side end of the element row without being slid by human force.

Description

technical field [0001] The present invention relates to a separate insert for a zipper having a slider for reverse opening, a box rod and a plunger, and more specifically relates to a reverse opening slider using a slider provided with a brake pawl. Detach the embed to open. Background technique [0002] Zippers are often used as opening and closing tools for opening and closing the openings of clothes and bags, and are also used as connecting tools for carpets and artificial turf divided by unit size. Slide fasteners are generally of the type that can be opened or closed from one end side to the other end side in the length direction of the element row, but there are also double-opening types that can be opened from both ends in the length direction of the element row, for example. Zipper, a type of zipper that can be locked from both end sides of the element row. [0003] For example, in the case of a double-open type slide fastener, two sliders, that is, a slider for op...

Problems solved by technology

Therefore, there is a disadvantage that the operation of the slider 90 for reverse opening is cumbersome.

[0022] In addition, if the front end of the brake pawl 92 is accidentally hung on the box bar main body 71 and the reverse opening slider 90 stops midway, the reverse opening slider 90 does not completely move to the end of the box bar 70 side. position, the left and right chain element rows 63 will be engaged by the unshown opening slider, which may cause the meshing of the chain element rows 63 to be incorrect and easily cause problems such as meshing and separation.
