Embodiment Construction

[0032] While the invention may be embodied in various forms, there are shown in the drawings and hereafter described what is presently preferred, it should be understood that the disclosure is considered exemplary of the invention and is not intended to be limiting of the invention shown. specific implementations.

[0033] see in general Figure 1-3 , shows a locking slider assembly (10) for a zipper. In its simplest form, the locking slider assembly (10) includes a slider member (12) and a puller member (14). The locking slide assembly (10) is preferably formed during a single operation in a die casting molding apparatus (not shown). The slider member (12) is formed to include bridges (16) for positioning and retaining the puller member (14) in a manner that allows rotation and some linear translation of the puller member (14). The bridge (16) is formed such that it does not include breaks or gaps that could weaken the bridge (16) and allow the pull member (14) to be relea...

Abstract

The invention involves a locking slide assembly for a zipper. The locking slider assembly is formed in a single die cast operation to include the locking slider (12) and the pull member (14) being formed simultaneously. At least one side shifting slide (46) is incorporated into the die, which allows the bridge (16) and pull loop (38) to be formed with their full geometric shape and without the converging flat surfaces.

Description

field of invention [0001] This invention relates generally to zipper fasteners commonly referred to as zippers, and more particularly to a one-piece locking slide and pull made of metal for zippers. Background technique [0002] A zipper (zipper, zip, fly or zip fastener), or slide fastener, formerly known as a clasp, is a common device used to bond the edges of openings in fabric or other flexible materials, such as on clothing or bags. It is used in clothing (such as jackets and jeans), luggage and other bags, sporting goods, camping gear, and other items. [0003] The main part of a zipper (zipper / zip) consists of two rows of protruding teeth that can be interlaced to connect them in equal rows, with tens to hundreds of specially shaped metal or plastic teeth. These teeth may be individual or formed from a continuous roll of stock, also known as an element. A manually operated slide moves along the rows of teeth. Inside the slider is a Y-shaped channel that meshes oppo...
