FASTENER SLIDER AND SLIDE FASTENER

WIPO Patent Application WO/2013/157141

A1

A fastener slider (100) comprises: a slider body (10) provided with an upper wing plate (16), a lower wing plate (15), and a connection column (17) which connects the upper wing plate (16) and the lower wing plate (15); a pull tab mounting column (20) provided on the slider body (10); and a pull tab (50) mounted in a swingable manner to the slider body (10) by the pull tab mounting column (20) and capable of falling or being inverted on the upper wing plate (16) or the lower wing plate (15). The pull tab (50) is configured from a wire material at least partially having elasticity and includes a set of extension bar sections (51b, 51d) extending between a base which serves as the center of swing of the pull tab (50) and a free end which is located at the other end relative to the base. The pull tab mounting column (20) includes a set of side surfaces (21p, 21q, 23p, 23q, 71p, 71q, 73p, 73q) on which the set of extension bar sections (51b, 51d) slide. In order to increase the distance between the set of extension bar sections (51b, 51d) of the pull tab (50) in a process in which the state of the pull tab (50) changes from a fallen state to an upstanding state, the distance between the set of side surfaces (21p, 21q, 23p, 23q, 71p, 71q, 73p, 73q) gradually increases from the side of the side surfaces on which the pull tab in the fallen state is located to the side thereof on which the pull tab in the inverted state is located.
