Strap structure

Abstract

A strap structure used as a strap for an object such as mask or swim fin is disclosed. The object has a locking receptacle on either side. The strap structure includes an elastic strap having a coupling member at either end, the coupling member being adapted to releasably secure to the locking receptacle; and an adapting assembly having one end adapted to releasably secure to the coupling member and the other end releasably secure to the locking receptacle. Moreover, the adapting assembly includes one or more adapters so that the strap structure is adapted to secure around one of the different objects with various sizes.

1 . A strap structure used as a strap for an object selected from a group consisting of swim mask, diving mask, athlete mask, safety glasses, safety goggles, and swim fin, the object having a locking receptacle on either side, comprising:
 a strap having a coupling member at either end, the coupling member being adapted to releasably secure to the locking receptacle; and   adapting means having one end adapted to releasably secure to the coupling member and the other end releasably secure to the locking receptacle so that the strap structure is adapted to secure around one of the different objects with various sizes.   
   
   
       2 . The strap structure of  claim 1 , wherein the strap is formed of a material selected from a group consisting of plastic, rubber, silicon rubber, thermoplastic rubber (TPR), TPE (thermoplastic elastomer rubber), synthetic material, polymeric material, leather, and metal. 
   
   
       3 . The strap structure of  claim 1 , wherein the strap and the coupling members are formed integrally. 
   
   
       4 . The strap structure of  claim 1 , wherein the strap and the coupling member are coupled together by hook and groove, screw fastening, Velcro fastening, tab and slot, or tying. 
   
   
       5 . The strap structure of  claim 1 , wherein the strap is formed of composite material.
