Abstract

A fastener structure is provided for fastening an elastic object and includes a bore-carrying fastening member and a pivot-carrying fastening member, which form grip band receiving holes and receiving channels and which have inner sides forming concave arc surfaces. The bore-carrying fastening member forms a bore that rotatably receives a pivot formed on the pivot-carrying fastening member therein. The locking member forms two flanges, which are respectively receivable in the receiving channels of the bore-carrying fastening member and the pivot-carrying fastening member so that the bore-carrying fastening member and the pivot-carrying fastening member are combinable together with the locking member with the concave arc surfaces of the bore-carrying fastening member and the pivot-carrying fastening member and a concave arc surface of the locking member together define and delimit a conic bore for receiving and fastening the elastic object.

Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention generally relates to a tension cod fastener structure, which comprises a bore-carrying fastening member, a pivot-carrying fastening member, and a locking member, which are releasably combinable to fasten an end of a tension cord therebetween and prevent the tension cord from sliding off the fastener structure in the use thereof.DESCRIPTION OF THE PRIOR ART

[0002] Body fitting facility or exercise equipments often use an elongate elastic object, which is for example a metal spring or a cord made of synthetic fibers or high-molecule polymers each having its own advantages and disadvantages. Among these elastic objects, a high-molecule polymer cord has the advantages of light weight and high extensibility and is easy for carrying and use. However, such a material of light weight and high extensibility is hard to have ends thereof properly and securely fastened. An unexpected loosening of the elastic object during the use thereof...
