Abstract
A slide fastener includes first and second stringers, an intermediate body, a first slider, and a second slider. The first and second stringers are separated by a first lateral distance in a first longitudinal portion, the first and second stringers are separated by a second lateral distance in a second longitudinal portion. A transition portion extending along at least a portion of a longitudinal extent of the intermediate body interposes the first and second longitudinal portions, and the second lateral distance is greater than the first lateral distance.
Claims14
A slide fastener comprising:
- first and second stringers, each of the first and second stringers comprising a tape and first and second spaced sets of coupling elements disposed along two spaced portions of an edge of the tape, each set of coupling elements having a pitch spacing;
- an intermediate body fixedly attached to both the first stringer and the second stringer, the intermediate body interposing the two portions of each edge of the tapes of the first and second stringers;
- a first slider being traversable along a longitudinal axis along a first of said two spaced portions of each of the edges of the tapes, movement of the first slider in one direction being configured to cause the coupling elements disposed along a first of said two spaced portions of each of the edges of the tapes to interdigitate with one another;
- a second slider being traversable along the longitudinal axis along a second of said two spaced portions of each of the edges of the tapes, movement of the second slider in the one direction being configured to cause the coupling elements disposed along the second portion of each of the edges of the tapes to interdigitate with one another;
- and
- wherein the first and second stringers are separated by a first lateral distance in a first longitudinal portion, the first and second stringers are separated by a second lateral distance in a second longitudinal portion,
- the first lateral distance is a distance between the first and second stringers at a first end of the intermediate body, the second lateral distance is a distance between the first and second stringers at a second end of the intermediate body, and
- a transition portion extending along at least a portion of a longitudinal extent of the intermediate body interposes the first and second longitudinal portions, and the second lateral distance is greater than the first lateral distance.

- and
- wherein a maximum longitudinal extent of the intermediate body is greater than or equal to a distance equal to five pitch spacings.
