摘要:
The invention provides a separable bottom end stop for a concealed slide fastener, in which reinforcement portions (20, 21) for reinforcing bent edge portions (24) of a fastener tape (T) are respectively molded integrally with a box pin (2) and a separable pin (3) using resin, such that the reinforcement portions (20, 21) are swollen from a top surface of the fastener tape (T), while the reinforcement portion (20) on the side of the box pin (2) is formed such that a bottom end thereof is in the same plane as the box pin (2). A front end of the reinforcement portion (21) on the side of the separable pin (3) has a protruded portion (32) which is protruded in parallel to the separable pin (3) and a box (1) has an L-shaped engaging portion (17) and a contact portion (16), provided on a surface thereof. When the box pin (2) is inserted into and fixed to the box (1) while the separable pin (3) is inserted into an insertion hole (6), the protruded portion (32) of the reinforcement portion (21) makes contact with the engaging portion (17). Consequently, when the separable pin (3) is inserted into the box (1), the separable pin (3) never rolls inside the box (1) due to pulling force.

In a separable bottom end stop for a slide fastener in which protruding guide portions (4, 10) which protrude onto respective fastener tapes are integrally molded with respective side surfaces at the tape-side of a box pin (2) and an insert pin (3), via thin guide portions (5, 11), the separable bottom end stop is formed of polyacetal resin, and a distance d between each of the outer side faces of the box (1) and each of the protruding guide portions (4,10) when the box pin (2) and the insert pin (3) are mounted into the box(1), and the protrusion height h of each of the protruding guide portions (4,10) from a surface of each of the thin guide portions (5,11) satisfy the following relational equation: tan -1 ( d / h ) ≥ 33°, where d ≠ 0. Consequently, the tendency for breakage which occurs with polyacetal resin is eliminated physically. Thus, such a separable bottom end stop for a slide fastener is provided that has various applications in relevant fields; uses a material which allows various coloring to be achieved easily; and has excellent durability.

In a bottom stop assembly for a separable slide fastener, an open box (14) has a first channel (47) for receiving a box pin (8) firmly attached on an end of a stringer (4). The open box (14) has front and rear walls (26, 28) between which a web (30) intervenes at their intermediate portions. Right and left flanges (44, 40) define with the web (30) and the front and rear walls (26, 28) the first and a second channel (47, 43) for receiving an the box pin (8) and an insert pin (16) firmly attached on the lower ends of the other stringer (20). The channel (47) on the box pin insertion side has projections (48) on the flanges (44) extending inwardly, the projections urging the box pin (8) against the web (30). Upper and lower engaging surfaces (54, 56) formed by a cut-out (50) embrace the web (30) from up and down to limit axial movement of the box pin (8) in the open box (14). A bulge (60) on the lower end of the box pin (8) bears against the flanges (44) presses the projections (48) to urge the box pin (8) against the web (30). With these arrangements, any movement of the box pin (8) inside the box (14) is completely restricted.

摘要:
A Self-Aligning Zipper is disclosed that allows for one handed operation by anyone who would otherwise use a zipper or use of the Self- Aligning Zipper by those with physical and developmental limitations or equipment, such as cold weather gloves or mittens. The proper alignment of each half of the Self-Aligning Zipper is accomplished by way of magnets of opposite polarity along with structural, guide elements to ensure proper alignment and operation of the zipper.
