  • Patent number: 4665592
    Abstract: In a swivel snap hook of synthetic resin, a unitary hook member has a hook body and a resiliently deformable closure tongue molded integrally therewith, a free end of the closure tongue being, as the latter is in a free form, disposed inwardly of a free end of the hook body with a relatively small gap therebetween. In use, as the closure tongue is depressed inwardly against its resilience by a ring-shaped article to be threaded onto the hook body, the free end of the closure tongue is spaced wider from the free end of the hook body to open the latter. In production, the unitary hook member is molded on a specific mold in such a state or condition that the free end of the closure tongue is disposed inwardly of the free end of the hook body with the small gap therebetween.

  • Patent number: 4650104
    Abstract: A positioning device comprises a reciprocably movable support table having a surface extending in a plane above a clinching die of a button setting machine for supporting a garment fabric to which a button is to be attached, and a pair of guide members disposed on the surface in perpendicular relation. The table includes a recess which is registry with the clinching die when the table is in an advanced position. One of the guide member is positionally adjustable in a direction perpendicular to the direction of movement of the table and the other guide member is positionally adjustable in a direction parallel to the direction of movement of the table. Thus the garment fabric can be positioned accurately and easily with respect to the clinching die by simply putting two adjacent edges of the garment fabric into guided engagement with the respective guide members.

  • Patent number: 4639983
    Abstract: A hook for a hook-and-eye fastener includes a one-piece hook body having at least one pair of prongs, and a retainer having openings through which the prongs extend, respectively. The hook body includes a locking tongue and a base underlying the locking tongue, and an arcuate portion joining the locking tongue and the base, the prongs projecting substantially perpendicularly from the base in a direction away from the locking tongue. The hook body has a plurality of cold-pressed elongated recesses defined in an inner surface of the hook body and extending from the base through the arcuate portion to the locking tongue, thereby giving resilience and strength that are large enough to withstand forces tending to permanently deform the hook body at the arcuate portion. The openings in the retainer are spaced from one another by a distance which is larger than the distance between the prongs. Each of the prongs has a bent end portion retained on the retainer with a space defined therebetween.

  • Patent number: 4637099
    Abstract: A molded strap fastener of a generally rectangular shape includes a first cross bar for retaining therearound a looped end portion of a strap, a retainer portion disposed laterally adjacent to the cross bar and frictionally engageable with the strap end portion, and a second cross bar fixedly connected to the other strap end. The first cross bar includes a pair of diametrically opposite sharp corners and the retainer portion has a sharp corner, these sharp corners serving as stops to retain the strap in position against accidental displacement even under heavy tensioning forces. To provide a greater resistance to strap loosening, the first and second cross bars lie in different levels so that a rotational force is created upon the fastener when the latter is in actual use, said force growing greater the larger the tension and thus urging the retainer portion to firmly grip the strap end at its sharp corner.
