Abstract: A slide fastener chain includes first and second rows of coupling elements mounted on first and second longitudinal edges of the first and second fastener tapes. When the first and second rows of coupling elements are interdigitated, the first and second longitudinal edges remain spaced apart, and a first coupling element of the first row is received between two adjacent coupling elements of the second row such that: the groove of the first coupling element receives, in a first contact region, a portion of the second longitudinal edge, one of the grooves of the adjacent coupling elements receives, in a fourth contact region, a first portion of the first longitudinal edge, and another of the grooves of the adjacent coupling elements receives, in a fifth contact region, a second portion of the first longitudinal edge.

Abstract: A first stop member includes a first base and a first insert that is positioned between the first base and a first fastener element and is inserted into the slider via a rear mouth of a slider. A second stop member includes a second base and a second insert that is positioned between the second base and a second fastener element and is inserted into the slider via a second slit of the slider. The second insert moves toward the second slit of the slider in accordance with at least one or respective rotations of the first and second bases. A rotational axis with respect to the at least one or respective rotations of the first and second bases is positioned between the first tape region and the second tape region.

Abstract: A rotational mechanism of a separable stop member for a slide fastener may include: a first member including a first main body, an opening provided in the first main body, and one or more first contact portions provided in the opening; and a second member including a second main body, and one or more second contact portions provided, as a protrusion, in the second main body. One of the first and second contact portions may include an arc-shaped sloped surface extends in an arc about a rotational axis, and the other one of the first and second contact portions may include a sliding portion that slides on the arc-shaped sloped surface. The sliding portion may slide on the arc-shaped sloped surface such that at least one of the first and second main bodies is rotated about the rotational axis.

Abstract: There is provided an element for a fastener chain. The element includes a body portion fixed on a core portion of a tape, a neck portion, a pair of shoulder portions, an engaging head portion, and a pair of groove portions. As viewed in the width direction, at least one of the pair of shoulder portions and the pair of groove portions is configured to be inclined with respect to a reference direction, which is an extending direction of the core portion on which the body portion is fixed.
