Abstract
A slide fastener includes first and second rows of slide elements and first and second tapes secured with the respective rows of slide elements. The slide elements of the first row of slide elements are configured to engage with slide elements of the second row of slide elements and each slide element of the first and second rows includes a base, a head, a neck extending between the base and the head, a top surface, a facing surface, and one or more shoulders. A first vertical distance between a lowermost surface of the head and the first end of the first tape is greater than a second vertical distance between a lowermost surface of the base and the first end of the first tape.
Claims25
A slide fastener comprising:
- a first row of slide elements;
- a second row of slide elements;
- a first tape connected with the first row of slide elements at a first end of the first tape;
- and
- a second tape secured with the second row of slide elements at a first end of the second tape, wherein:
- slide elements of the first row of slide elements are configured to engage with slide elements of the second row of slide elements;
- each slide element of the first and second rows comprises a base, a head, a neck extending between the base and the head, a top surface, a facing surface, and one or more shoulders;
- each base comprises an upper portion disposed above a through hole and a lower portion disposed below the through hole, wherein the upper and lower portions are integrally connected with each other at rear sides thereof;
- the first tape is disposed in the through hole of the first row of slide elements and is configured to cover the facing surface and the top surface of each of the slide elements of the first row;
- the second tape is disposed in the through hole of the second row of slide elements and is configured to cover the facing surface and the top surface of each of the slide elements of the second row;
- and
- a first vertical distance between a lowermost surface of the head and the first end of the first tape is greater than a second vertical distance between a lowermost surface of the base and the first end of the first tape.

A slide fastener comprising:
- a first row of slide elements extending along a longitudinal direction;
- a second row of slide elements extending approximately parallel to the first row when the first and second rows are engaged with one another;
- a first tape having a first end that is disposed in a through hole of each of the slide elements of the first row of slide elements;
- and
- a second tape having a first end that is disposed in a through hole of each of the slide elements of the second row of slide elements;
- wherein:
- each slide element comprises a base, a head, a neck extending between the base and the head, a top surface, a facing surface, and one or more shoulders;
- each base comprises an upper portion disposed above the through hole and a lower portion disposed below the through hole, wherein the upper and lower portions are integrally connected with each other at rear sides thereof;
- the slide elements are disposed such that the facing surfaces of the slide elements of the first row and the facing surfaces of the slide elements of the second row face one another;
- the first tape is configured to cover the facing surface and the top surface of the slide elements of the first row;
- the second tape is configured to cover the facing surface and the top surface of the slide elements of the second row;
- the first and second tapes are pressed together between the first and second rows of slide elements when the first and second rows are engaged with one another;
- a lowermost surface of the head of each of the slide elements is contained within a first plane that is offset toward a bottom portion of the slide element from a second plane containing a lowermost surface of the base;
- and
- a forwardmost surface of the head of each of the slide elements is contained within a third plane that is offset toward a front portion of the slide element from a fourth plane containing the facing surface of the base, wherein the facing surface is a forwardmost surface of the base.
12 more elements
