Abstract: The invention is a single-action double-lock snap, a snap hook having a lock arm. The hook includes a shank with a hook at one end of the shank. The other end of the snap is connected to a cable or a lanyard and in use, the hook is connected to an anchor eye or the like. To avoid accidental disengagement of the hook from the anchor eye, a lock arm, or gate, is pivoted on the shank of the hook to reach across the throat of the hook to engage the point of the hook. This lock arm will thus normally lock the hook upon an anchor eye. However, the possibility exists that the hook can be accidentally opened to release the hook from the anchor eye whenever the snap is swung about while connected to the anchor eye. A detent is pivotally mounted upon the shank to bear against a seat on the lock arm whenever the lock arm is extended to close the throat of the hook. When the detent is so seated, the lock arm cannot be opened.

Abstract: A slider for use in a slide fastener prevents jamming of a foreign matter within the slider between fastener elements and inner element-guide portions of the slider. The slider has a diverging end and a contracted end, and the diverging end has two openings which are partitioned by an interconnecting web. The two openings lead to two channels which are joined together in the half portion of the slider on the side close to the aforesaid contracted end. The separated fastener elements secured to fastener tapes, respectively, and introduced through the aforesaid channels into the slider are brought into engagement with each other in the aforesaid half portion of the slider. In such a case, a foreign matter, such as a piece of cloth, often jams between the fastener elements and the inner element-guiding portions of the slider.

Abstract: A slide fastener comprising a box-and-pin separable coupling and an automatically locking slider. The slider has a locking member pivoted at one end on the slider body and having first and second legs formed adjacent its other end in side-by-side disposition. The first leg of the locking member is normally spring-biased into a position of interference with the pin-side row of fastener elements when the slider is riding on both rows of fastener elements, and the second leg is disposed opposite to the box-side row of fastener elements. When the slider is moved into abutting contact with the box member of the separable coupling, the second leg of the locking member rides onto a protuberance formed on the guide bar of the box member, so that the first leg of the locking member is retracted from its interference position against the bias of the spring to permit smooth insertion of the pin member of the separable coupling into the box member through the slider.

Abstract: A dual zipper construction provides a double closure to discourage opening of the zippered enclosure. The zippers co-extend, one above the other, with the upper zipper closing in a direction opposite that of the lower zipper. Each zipper has its engaging surface mounted on a pair of flaps, with one flap being longer than the other. When assembled, the longer flap on the upper zipper overlies the shorter flap on the lower zipper thus offsetting the opening and closing tabs of the two zippers, facilitating closure.
