US 5,848,454 A · Strapping system and fastener therefor

Abstract

A strapping system using a novel buckle wherein one end portion of the buckle is attached to one end of a flat non-metallic strap, and the other end of the strap is threaded though the buckle in such a manner that the strap is held securely in place, and wherein the buckle is of a unitary structure comprising the attaching end portion and the threaded end portion in which are located two outer parallel legs and a center leg with two slots respectively therebetween, and with the walls of the slot closest to the attaching end being generally parallel to each other and positioned at an angle of between 45.degree. and up to less than 90.degree. as measured from the top or bottom surface of the buckle depending on the orientation of the walls of the slot. In another embodiment, instead of the strap being attached to the one end of the buckle, two sets of slots are formed by two sets of parallel outer legs and and other center leg, whereby both ends of the strap are threaded through respective slots in the two ends of the buckle.

Dependent claims

A rigid buckle made of plastic resin and formed as a unitary structure consisting of:

an end portion formed of a bottom surface and a top surface, one of which has permanently attached thereto a flat end surface of a non-metallic strap;
a main portion connected to said end portion and consisting of a rigid flat top surface and a rigid flat bottom surface, and therebetween two parallel outer parts and a parallel center part disposed between said two parallel outer parts and consisting of a pair of slots defined therebetween, one of said slots closest to said end portion consisting of a pair of side walls and a pair of parallel walls oriented at an angle of between 45.degree. and up to less than 90.degree. as measured from said top surface or said bottom surface of said main portion, wherein said flat surface of said end portion is co-extensive with one of said flat top surface and said flat bottom surface of said main portion so that said strap is threaded through said pair of slots and locked in a threaded position.

A self-locking rigid buckle made of plastic resin and formed as a unitary structure consisting of:

two parallel outer portions, a plurality of parallel transverse portions connected perpendicular to said two parallel outer portions, and consisting of two outer slots and two inner slots formed between said two outer slots, wherein said two inner slots consist of a pair of outer walls and parallel walls oriented at an angle of between 45.degree. and up to less than 90.degree. as measured from a top surface or a bottom surface of said unitary structure, wherein said top surface and said bottom surface are flat and parallel to each other so that a non-metallic strap threaded through said slots are locked in a threaded position by said buckle.
