Abstract

Various implementations include a slide fastener that has a blocking element on one stringer that prevents engagement compatibility with standard elements on the other stringer. For example, at least one blocking element is coupled to a first stringer, and first and second blocking coupling elements are coupled to a second stringer. The contour of the blocking element and the contour of the blocking coupling elements are different from the contour of the standard elements on the stringers such that the standard elements do not engage with the blocking element or the blocking coupling elements in an alternating arrangement. However, the contour of the blocking element and contour of the blocking coupling elements allow for the engagement of the blocking element with the blocking coupling elements in an alternating arrangement.

A slide fastener comprising:

first and second stringers, each stringer comprising a tape and a plurality of elements disposed on an inner edge of the tape, the tape being within a fastening plane, and the inner edges facing each other within the fastening plane,
a slider slidably coupled to at least one of the stringers, the slider coupling the plurality of elements of the stringers when the slider is urged in a first sliding direction within the fastening plane and decoupling the plurality of elements when urged in a second sliding direction within the fastening plane, the second sliding direction being opposite the first sliding direction,
wherein:
the plurality of elements of the first stringer and the second stringer comprises a plurality of standard elements,
the plurality of elements of the first stringer further comprises a blocking element,
the plurality of elements on the second stringer further comprises first and second blocking coupling elements,
engagement portions of at least a portion of the standard elements on the first tape engage between engagement portions of at least a portion of the standard elements on the second tape in an alternating arrangement in the sliding directions, and vice versa, when the slider is urged over the standard elements in the first sliding direction,
engagement portions of the blocking element engage between engagement portions of the first and second blocking coupling elements when the slider is urged over the blocking element and the blocking coupling elements in the first sliding direction, and
a contour of the blocking element and a contour of the blocking coupling elements are different from a contour of the standard element such that the engagement portions of the standard elements on the second tape do not engage with the engagement portions of the blocking element on the first tape in an alternating arrangement in the sliding directions, and the engagement portions of the standard elements on the first tape do not engage with the engagement portions of the blocking coupling elements on the second tape in an alternating arrangement in the sliding directions.
