Light-reflective slide fastener

Claim 2

A light-reflective slide fastener which comprises: a pair of support tapes each carrying on their respective longitudinal inner edges a row of coupling elements in the form of intermeshing teeth, each of said elements having a coupling head portion, a leg portion and a heel portion, said coupling elements having recesses which form a continuous recess along said row of coupling elements; a slide adapted to bring said elements on the respective tapes into and out of engagement; and a continuous flexible light-reflective strip extending longitudinally at least partially over and secured in said continuous recess of said row of coupling elements and disposed independently from any portion of each of said tapes.

Claim 3

A light-reflective slide fastener as defined in claim 1 wherein said strip is secured to said row of elements by means of fusion.

Claim 4

A light-reflective slide fastener as defined in claim 1, wherein said strip comprises a base layer, a reflective layer bonded thereto by applying a metal, an adhesive layer laid over said reflective layer and a multiplicity of glass beads embedded substantially halfway in said adhesive layer.

Claim 5

A light-reflective slide fastener as defined in claim 3 wherein said strip further comprises a transparent cover layer extending over and enveloping said glass beads.

Claim 6

A light-reflective slide fastener as defined in claim 3 wherein said reflective layer extends in a wavy configuration as cross-sectionally viewed.

Claim 7

A light-reflective slide fastener as defined in claim 1, wherein ones of said elements are provided with reservoirs in said recesses adpated for receiving therein an adhesive compound.

Claim 8

A light-reflective slide fastener as defined in claim 1, wherein said strip is secured to said row of elements by means of adhesion.

Claim 9

A light-reflective slide fastener as defined in claim 1, wherein said strip is secured to said row of elements by means of sewing.

Claim 10

A light-reflective slide fastener which comprises: a pair of support tapes each carrying on their respective longitudinal inner edges a row of coupling elements in the form of intermeshing teeth, each of said elements having a coupling head portion, a leg portion and a heel portion; a slide adapted to bring said elements on the respective tapes into and out of coupling engagement; and a flexible light-reflective strip extending longitudinally at least partially over and secured to upper surfaces of said row of coupling elements and disposed independently from any portion of each of said tapes, said light-reflective strip being disposed in sagged relation with concave portions in gaps in between adjacent ones of said coupling elements to prevent tearing of said strip during coupling and uncoupling of said coupling elements.

Claim 11

A light-reflective slide fastener which comprises: a pair of support tapes each carrying on their respective longitudinal inner edges a row of coupling elements in the form of intermeshing teeth, each of said elements having a coupling head portion, a leg portion and a heel portion; a slide adapted to bring said elements on the respective tapes into and out of coupling engagement; and a flexible light-reflective strip extending longitudinally at least partially over and secured to upper surfaces of said row of coupling elements and disposed independently from any portion of each of said tapes, said light-reflective strip being disposed in sagged relation with concave portions in gaps in between adjacent ones of said coupling elements to prevent tearing of said strip during coupling and uncoupling of said coupling elements.

Claim 12

A light-reflective slide fastener as defined in claim 6 wherein said light-reflective strip extends longitudinally more extensively over and secured to the upper surfaces of said row of elements so as to mask substantially the entirety of said elements from view when the fastener is closed.
