  • Patent number: 10369909
    Abstract: A surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.

  • Publication number: 20130133176
    Abstract: Disclosed is a surface fastener with a plurality of male engaging elements installed on the surface of a plastic substrate. Specifically disclosed is a molded surface fastener wherein the male engaging elements have a stem that rises from the plastic substrate and protrusions for engaging that protrude from the stem to the side. The ratio (D/H) between the height (H) of the engaging elements from the substrate and the length (D) from the peak of the engaging elements to the lower end section of the protrusions is 0.35-0.75 and the rate of substrate coverage by the engaging elements is 25%-45%. The disclosed male molded surface fastener is an improvement on surface fasteners, particularly male molded surface fasteners, that engage when simply overlapped which makes positioning extremely difficult. The disclosed male molded surface fastener almost never engages when positioning and has a high engaging force after final fastening.

  • Patent number: 8399086
    Abstract: A mold-in fastening member which is composed of a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate. The mold-in fastening member bends in conformity with a two- or three-dimensionally complicated shape of a molded article. The mold-in fastening member prevents the surface having the engaging elements from being covered with a foamable liquid molding resin during a mold-in process, thereby preventing the engaging elements from losing the engaging function.
