  • Patent number: 4819303
    Abstract: An article injection molded from a thermoplastic material, e.g., a polypropylene or acetal polymer, for use as a belt loop stay. A first strip is provided at each end with a flange. When unstressed, the first strip is straight, except for the flanges. A second strip, which is thinner so as to be more flexible, is joined integrally to the flanges, so as to form a closed loop. When unstressed, the second strip is bowed toward the first strip, between the flanges. The first strip has a stiffening rib, which stiffens the first strip against flexing on lateral axes. The second strip has several stiffening ribs, which stiffen the second strip against flexing on longitudinal axes but permit the second strip to flex on lateral axes. Beveled edges on the first strip facilitate insertion of a belt from either side of the first strip.

  • Patent number: 4665590
    Abstract: A cord retainer assembly constructed of two cooperating parts: a cord holder part and a cord lock part. The cord holder part is molded as a one-piece plastic elongate housing having a tapered nose portion with two spaced apart apertures formed at one end and having a central opening formed at the other end. The cord lock part is formed of a one-piece plastic elongate slider member which is conformably shaped to be slidably disposed within the hollow housing and has a handle portion which extends outwardly of its central opening. The slider member is formed with a pair of laterally extending gripping teeth for selectively restraining a length of cord which is threaded through the housing. The slider member is releasably latched within the housing member by a ratcheting mechanism composed of a plurality of serrated teeth formed longitudinally along an inside surface of the housing which mate with a second plurality of serrated teeth formed longitudinally along the slider member.
