Abstract
There is provided a stop for a slide fastener. A top plate and a bottom plate are linked with one another at a transversely intermediate position by an integral connecting post. The lower side of the top plate is substantially flat. The bottom plate slopes away from the connecting post to form two leg members provided with a respective end flange pointing towards the top plate, the leg members being adapted to cooperate in use with the top plate to retain fastener tapes therebetween.
Claims15
A stop for a slide fastener, comprising a top plate and a bottom plate linked with one another at a transversely intermediate position by an integral connecting post,
- wherein in a condition before the stop is crimped onto the slide fastener,
- an upper side of the top plate is substantially flat and a lower side of the top plate is flat;
- and
- the bottom plate includes a pair of leg members which slope away from the connecting post,
- wherein the stop is crimped onto fastener tapes of the slide fastener by deforming the pair of leg members of the bottom plate without substantially deforming the top plate, and
- wherein in a condition after the stop is crimped onto the slide fastener, the pair of leg members are provided with a respective end flange pointing towards the top plate and adapted to cooperate in use with the top plate to retain the fastener tapes therebetween,
- wherein in the condition after the stop is crimped onto the slide fastener, an upper side of each of the leg members of the bottom plate has a sloping surface extending from the respective flange towards a proximal portion of each of the leg members, and
- wherein the bottom plate is shaped such that in the condition after the stop is crimped onto the slide fastener an entire lower side of the bottom plate is flat.

- and
- the bottom plate includes a pair of leg members which slope away from the connecting post,
- wherein the stop is crimped onto fastener tapes of the slide fastener by deforming the pair of leg members of the bottom plate without substantially deforming the top plate,
- wherein in a condition after the stop is crimped onto the slide fastener,
- the pair of leg members are provided with a respective end flange pointing towards the top plate and adapted to cooperate in use with the top plate to retain fastener tapes therebetween, and
- wherein in the condition before the stop is crimped onto the slide fastener, a proximal portion of each of the leg members of the bottom plate forms a convex protrusion adjacent the connecting post.
