Abstract
A buckle achieves improved strap tensile strength by providing a bridge portion, about which a free end of a buckle strap is wrapped in tension, with an inwardly projecting concave surface to create a greater deformation of the strap under tension. The buckle also includes at least one strengthening cross rib on the bridge portion and a strap receiving inset with a concave shaped pocket to improve the strap tensile strength. Furthermore, the buckle includes a bendable retainer element with an inwardly directed clamping tab near its free moving end to retain a portion of the strap within the buckle.
Claims5
A buckle for fastening opposing ends of an object encircling strap, comprising:
- a first bridge portion partially defining an inlet portion;
- a second bridge portion partially defining an exit portion, the second bridge portion having a concave surface extending across the second bridge portion from a first side of the second bridge portion to a second side of the second bridge portion;
- a retention window provided between the first and second bridge portions;
- and
- a deformable retainer extending from the buckle intermediate the first and second bridge portions and deformable from a generally upright first position to a strap engaging second position within the retention window.
A buckle for fastening opposing ends of an object encircling strap, comprising:
- a first bridge portion partially defining an inlet portion;
- a second bridge portion partially defining an exit portion, the second bridge portion having a sloped surface inwardly directed toward a floor of the buckle;
- a retention window provided between the first and second bridge portions;
- and
- a deformable retailer extending from the buckle intermediate the first and second bridge portions and deformable from a generally upright first position to a strap engaging second position within the retention window.
A buckle for fastening opposing ends of an object encircling strap;
- comprising:
- a first bridge portion partially defining all inlet portion;
- a second bridge portion partially defining all exit portion, the second bridge portion having a strengthening rib for preventing the second bridge portion from bowing when the strap is installed around the second bridge portion;
- a retention window provided between the first and second bridge portions, and
- a deformable retainer extending from the buckle intermediate the first and second bridge portions and deformable from at generally upright first position to a strap engaging second position within the retention window.
