Appl. No.:

5/803551

Inventors:

Jonathan E. Sharp - Littleton CO

International Classification:

E06C 718

US Classification:

182 3

Abstract:

The present invention is a shock absorber for a safety belt lanyard. It comprises, in essence, a strap-like web of strength sufficient to check a fall, having a short base portion at one end and a free reach constituting the remainder. The end of the base portion connects with the center bar of a three-bar slide and the junction between the base portion and the free reach is a connector loop to connect with a lanyard or safety belt. The free reach, commencing at the loop, has its extended end threaded through the three-bar slide to terminate as a second connector loop opposite the first mentioned connector loop to connect with the safety belt or lanyard. The free reach of the web is folded against the base to provide a compact package which is enclosed in a disruptible cover to complete the unit. In use, the free reach is pulled through the three-bar slide to provide the necessary resistance to decelerate the fall.

International Classification:

A44B 1302

US Classification:

24241SB

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.
