Abstract
An end stop for slide fasteners includes a rectangular block molded on a portion of folded inner longitudinal tape edges including a plurality of coupling elements mounted thereon, and an integral peripheral seat attached to opposed stringer tapes. The block has an end wall engageable with the slider, and a recess extending in the end wall and defined by and between the block and a portion of the peripheral seat. The portion of the peripheral seat terminates slightly short of the end wall of the block with the result that the slider is brought into abutment with the block without interference with the peripheral seat. The recess serves to absorb shock force which would otherwise be transmitted directly to the peripheral seat when the slider impinges on the block.
Claims5
A slide fastener comprising:
- (a) a pair of slide fastener stringers each having a stringer tape and a row of coupling elements mounted on and along a folded inner longitudinal edge of each stringer tape;
- (b) a slider slidably mounted on the two rows of coupling elements to take the latter into and out of coupling engagement with each other to close and open said slide fastener;
- and
- (c) an end stop mounted on said stringer tapes adjacent to one end of said rows of coupling elements for limiting movement of said slider, said end stop including a substantially rectangular block attached to a portion of said folded inner longitudinal edges including a plurality of coupling elements, and a flared bottom peripheral seat integral with said block and attached to said stringer tapes, said block having an end wall engageable with said slider and a cut-out recess extending in said end wall and defined by and between said block and a portion of said peripheral seat, said portion of said peripheral seat terminating slightly short of said end wall.
