Abstract
The device provides a locking slide assembly for a zipper, and a method for manufacturing a locking zipper slide assembly. The locking slider assembly is formed in a single die cast operation to include the locking slider and the pull member being formed simultaneously. Whereby the bridge and pull loop are formed with their full geometric shape and without converging flat surfaces caused by tooling limitations found in the prior art.

A locking slide assembly for a zipper comprising:
- a slide member (12), said slide member (12) being constructed and arranged to open and close a zipper chain (94), said slide member (12) including a slide top (23), said slide top (23) having a top surface (24) and a lower guiding surface (86), a slide bottom (88) having a bottom surface (25) and an upper guiding surface (90), said slide top (23) and said slide bottom (88) separated by an integrally formed splitter (34) to form a Y-shaped channel (92) between said slide top (23) and said slide bottom (88) for guiding said zipper chain (94) therethrough, said splitter integrally formed to a bottom surface of said upper guide and a top surface of said lower guide such that said slide member is a single piece, said top surface (24) including a bridge (16) having a first end (18) and a second end (20) said bridge integrally formed to said top surface (24) as a continuous member not having breaks along the length of said bridge, a bridge inner surface (26) defining an opening between said bridge (16) and said top surface (24) of said slide member (12) for through passage of a loop portion of a metal pull member (14), and a pair of bridge side surfaces (21), said bridge (16) including an insertable locking member (82) extending into said Y-shaped channel (92) for engaging a portion of said zipper chain (94) to resist unwanted movement of said slide member (12) with respect to said zipper chain (94);
- said pull member (14) constructed from metal and having a loop portion (38) and a first tab portion (40), said loop portion (38) formed as a continuous unbroken loop around said bridge (16) and integrally formed to said first tab portion (40), said pull member (14) being movable to disengage said locking member (82) from said zipper chain (94) to provide free movement of said slide member (12);
- said slide member (12) and said pull member (14) both formed of metal to be continuous and unbroken, said pull member (14) being freely moveable with respect to said slide member (12).
