  • Patent number: 6877192
    Abstract: Both sides of a fastener chain may be reinforced and an attachment object such as a bag or a case may be mounted in a stabilized condition. A reinforcement member, which is molded of thermoplastic resin, thermoplastic elastomer or synthetic rubber in the form of a turned-down U shape in its cross section and has an appropriate plasticity and flexibility, is bonded along both outer sides of a fastener chain with a thermal welding resin film. The reinforcement member has a mounting groove which enables a cloth of the attachment object such as the bag or the case to be mounted and further contains a concave groove for a sewing thread, provided in the surface thereof. The cloth of the attachment object is inserted into the mounting groove and sewed along the concave groove with a sewing thread. Consequently, the reinforcement member can be mounted simply in a stabilized condition and can ensure a long term use.

  • Patent number: 5615461
    Abstract: A fastening device molded of a synthetic resin material and adapted to be engaged with a large number of loops on one surface of a fastener part of a mating member includes a base member having on its one surface a large number of hooks integrally molded with the base member and arranged in a plurality of rows. The hooks in each hook row generally have the same hook direction aligned with an axis of the hook row, and the hooks in one hook row and the hooks in an adjacent hook row do not always have the same hook direction. At least one hook in each hook row which is adjacent to a peripheral edge of the base member have a hook direction facing outwardly away from the peripheral edge. With this arrangement, the hooks located adjacent to the peripheral edge are capable of withstand undue force tending to fatigue and eventually break the hooks.

  • Patent number: 5551130
    Abstract: In a hook structure for a molded surface fastener, each of hooks is composed of a rising portion, which has a rear surface rising obliquely in a smooth curve from the substrate, a front surface rising upwardly from the substrate, and side surfaces from at least one of which a reinforcing rib extends, and a hook-shape engaging portion extending forwardly from an upper end of the rising portion. The engaging portion has a varying cross-sectional area increasing progressively from its distal end toward the upper end of the rising portion. A straight line between a peak of the rib and a peak of an arcuate lower surface of the engaging portion is substantially parallel to the upper surface of the substrate. The rib is rising upwardly and substantially centrally from a side surface of base of each hook.
