  • Patent number: 10306954
    Abstract: There is provided a side fastener chain. A plurality of elements are fixed on each of opposing edge portions of a pair of fastener tapes at a predetermined pitch. The elements include a base portion and a head portion. A ratio (Rt) of the sum dimension of a first partial thickness, which is measured from an upper surface of each element to an upper surfaces-side apex of the respective edge portion, and a second partial thickness, which is measured from a lower surface of the element to a lower surface-side apex of the edge portion, to a thickness of the element satisfies the following equation: 40%?Rt. A ratio (Rtl) of the thickness of the element to the entire length of the element satisfies the following equation: 0<Rtl<60%.

  • Patent number: 9854880
    Abstract: [Problem] To provide a slide fastener chain and a slide fastener, which have a small curvature radius and which have flexibility enabling the slide fastener chain and the slide fastener to be smoothly bent. [Solution] A slide fastener chain (1) comprises: a pair of fastener tapes (2); and elements (3) affixed to the facing edges (21) of the fastener tapes (2) at a predetermined pitch. The slide fastener chain (1) is characterized in that: the elements (3) each have bases (31a, 32a) affixed to a fastener tape (2) and each have heads (31c, 32c) protruding from the bases (31a, 32a) and engaging with facing elements (3); and the thickness (t) and pitch (p) of the elements (3) satisfy the following expressions (1) and (2).
