  • Patent number: 10251454
    Abstract: There is provided a slider cover of a slide fastener. An upper mounting plate includes: an upper plate to be arranged above an upper blade of a slider and formed with a through-hole penetrating therethrough; and an upper wall protruding downward from the upper plate. A lower mounting plate includes: a lower plate to be arranged below a lower blade of the slider; and a lower wall for surrounding front, right and left sides of an outer periphery of the lower blade and protruding upward from the lower plate. At least one of the upper and lower mounting plates includes a protrusion protruding from an inner peripheral surface of at least corresponding one of the upper and lower walls and configured to come in close contact with a part of an outer peripheral surface of at least corresponding one of the upper and lower blades.

  • Patent number: 10136707
    Abstract: A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.

  • Patent number: 9788615
    Abstract: These fastener elements have: an element main body portion having a coupling head portion; and first and second projections that project in a tape surface/rear-surface direction from the element main body portion. The first and second projections have a top surface, peripheral side surfaces standing upright from the element main body portion, and at least one sloped surface between the top surface and the peripheral side surfaces that has a different angle of inclination from the top surface and the peripheral side surfaces. As a result, the fastener elements appear long and narrow in the element length direction and have an external appearance close to that of a metal element. Furthermore, a stop claw portion is less likely to catch on the fastener elements when starting the sliding operation of a slider.
