Abstract
Official abstract text for this publication.
A slide fastener is provided. Each of a pair of first and second stringers includes a tape and a row of coupling elements mounted on a longitudinal edge of the tape. Each of the coupling elements comprises a first non-connecting portion at an upper side of the tape and a second connecting portion at a lower side of the tape. The second connecting portion comprises a head portion and a body portion. The head portion is engageable with a head portion of opposing coupling element. The body portion is fixed to the tape.
First claim
Opening claim text (preview).
The invention claimed is: 1. A slide fastener comprising: a pair of first and second stringers each comprising a tape and a row of coupling elements mounted on a longitudinal edge of the tape, wherein: each of the coupling elements comprises a first non-connecting portion at an upper side of the tape and a second connecting portion at a lower side of the tape, the second connecting portion comprises a head portion and a body portion, the head portion is engageable with a head portion of opposing coupling element, the body portion is fixed to the tape, in a direction perpendicular to a longitudinal direction of the first and second stringers, the second connecting portion is longer than the first non-connecting portion by an amount equal to substantially the size of the head portion of the second connecting portion, a shape of each of the coupling elements of the first stringer is identical with a shape of each of the coupling elements of the second stringer, the first non-connecting portion of each of the coupling elements is substantially square, in the longitudinal direction of the first and second stringers, the length of the head portion is less than the length of the body portion and the length of the head portion is less than the length of the first non-connecting portion, and wherein each of the coupling elements is fixed to the tape by clipping the tape between the first non-connecting portion and the second connecting portion. 2. The slide fastener according to claim 1 , wherein the first non-connecting portion has a flat upper surface. 3. The slide fastener according to claim 1 , wherein the first non-connecting portion has a front surface opposing in a front and rear direction of the coupling element when the head portion engages with the head portion of the opposing coupling element. 4. The slide fastener according to claim 1 , wherein the first non-connecting portion has a front surface and a rear surface which is arranged opposite to the front surface which are arranged parallel to the longitudinal direction of the first and second stringers. 5. The slide fastener according to claim 4 , wherein the second connecting portion has a rear surface which is arranged opposite to the head portion, and wherein the rear surface of the second connecting portion and the rear surface of the first non-connecting portion are flush with one another in a plane perpendicularly intersecting the tape.
