Claims
- 1. A strap adjustment assembly comprising:
- (a) a molded connector frame of synthetic resin including
- (1) a grip base having a flat strap bearing surface;
- (2) a pair of spaced legs extending integrally from opposite ends of said grip base and having a pair of transversely aligned slots, respectively, spaced from said flat strap bearing surface of said grip base by a distance, said slots having an oblong shape, and
- (3) a connecting bar extending integrally between said legs remotely from said grip base; and
- (b) a strap retainer of molded synthetic resin including
- (1) a central strap engagement portion, and
- (2) a pair of arms extending integrally from opposite ends of said central strap engagement portion and loosely fitted in said slots, respectively, said arms being disposed out of coaxial alignment with said central strap engagement portion and toward said connecting bar, said central strap engagement portion having a flat strap pressing surface extending parallel to said flat strap-bearing surface for frictionally pressing a strap end portion against said flat strap-bearing surface, said flat strap pressing surface being transversely spaced from said arms, at least by said distance, each of said arms having an elliptical cross section and being prevented from rotating in the respective oblong slots, said grip base, said legs, said connecting bar and said strap retainer being disposed in a plane lying substantially in the middle of the thickness of said strap adjusting assembly, said connector frame and said strap retainer having been molded in an assembled condition with said arms in said slots.
- 2. A strap adjustment assembly comprising:
- (a) a molded connector frame of synthetic resin including
- (1) a grip base having a flat strap bearing surface;
- (2) a pair of spaced legs extending integrally from opposite ends of said grip base and having a pair of transversely aligned slots, respectively, spaced from said flat strap bearing surface of said grip base by a distance, said slots having an oblong shape, and
- (3) a connecting bar extending integrally between said legs remotely from said grip base; and
- (b) a strap retainer of molded synthetic resin including
- (1) a central strap engagement portion, and
- (2) a pair of arms extending integrally from opposite ends of said central strap engagement portion and loosely fitted in said slots, respectively, said central strap engagement portion having a flat strap pressing surface extending parallel to said flat strap-bearing surface for frictionally pressing a strap end portion against said flat strap-bearing surface, said flat strap pressing surface being transversely spaced from said arms, at least by said distance, each of said arms having an elliptical cross section and being prevented from rotating in the respective oblong slots, said grip base, said legs, said connecting bar and said strap retainer being disposed in a plane lying substantially in the middle of the thickness of said strap adjusting assembly, said connector frame and said strap retainer having been molded in an assembled condition with said arms in said slots.
- 3. A strap adjustment assembly comprising:
- (a) a molded connector frame of synthetic resin including
- (1) a grip base having a flat strap bearing surface;
- (2) a pair of spaced legs extending integrally from opposite ends of said grip base and having a pair of transversely aligned slots, respectively, spaced from said flat strap bearing surface of said grip base by a distance, said slots having an oblong shape, and
- (3) a connecting bar extending integrally between said legs remotely from said grip base; and
- (b) a strap retainer of molded synthetic resin including
- (1) a central strap engagement portion, and
- (2) a pair of arms extending integrally from opposite ends of said central strap engagement portion and loosely fitted in said slots, respectively, said arms being disposed out of coaxial alignment with said central strap engagement portion and toward said connecting bar, said central strap engagement portion having a flat strap pressing surface extending parallel to said flat strap-bearing surface for frictionally pressing a strap end portion against said flat strap-bearing surface, said flat strap pressing surface being transversely spaced from said arms, at least by said distance, each of said arms having an elliptical cross section and being prevented from rotating in the respective oblong slots, said grip base, said legs, said connecting bar and said strap retainer being disposed in a plane lying substantially in the middle of the thickness of said strap adjusting assembly.
