Belt Pincher

Abstract

A belt pincher for holding a belt is disclosed. A loop made of the belt is constrained on a constrainer. The belt pincher has two opposite sidewalls. A restricting rod is fixedly interposed between the two sidewalls. A rotating arm is pivotally interposed between the two sidewalls. One end of the rotating arm is formed with an acting part. One end of the belt winds around the acting part and urges against the restricting rod. When the belt is pulled by the reaction of a constrained object, it pulls the rotating arm to pivotally rotate. As a result, the acting part and the restricting rod pinch to restrict and position the belt.

1 . A belt pincher for holding a belt that forms a loop to constrain an object, which comprises:
 two opposite sidewalls;   a restricting rod fixedly interposed between the two sidewalls; and   a rotating arm pivotally interposed between the two sidewalls;   wherein the restricting rod has an elastic element to impose a resilient force on the rotating arm toward the restricting rod; one end of the rotating arm is formed with an acting part; one end of the belt winds around the acting part and penetrates between the acting part and the restricting rod to urge against the restricting rod; when the belt is pulled by a reaction from the direction of the constrained object, the belt rotates the rotating arm so that the acting part and the restricting part pinch to restrict and position the belt.   
   
   
       2 . The belt pincher of  claim 1 , wherein when the belt is pulled by a reaction from the direction of the constrained object the overlapped belt winding around the acting part and the restricting rod further generates a resistance due to opposite-direction motions of the belt to restrict and position the belt. 
   
   
       3 . The belt pincher of  claim 1 , wherein a plate is punched to form a base with a U-shaped cross section so that the belt pincher has two opposite sidewalls and one bottom face between the two sidewalls; the two sidewalls are formed with a pivotal hole; one end of the bottom face is formed with a fixing end for fixing one end of the belt; the other end of the bottom face is formed with a notch; both sides of the rotating arm are extended with a connecting section, respectively, and the two connecting sections are formed with through holes corresponding to the pivotal holes on the base; a pivotal element simultaneously goes through the pivotal holes and the two through holes for the rotating arm to be pivotally interposed between the two sidewalls; the elastic element is disposed on the pivotal element; the end of the rotating arm corresponding to the restricting rod of the base is formed with the acting part, and the other end is formed with a pressing part; and a connecting hole is formed between the acting part and the pressing part. 
   
   
       4 . The belt pincher of  claim 3 , wherein the side of the notch is bent upward, opposite to the bottom face, to form a guiding section. 
   
   
       5 . The belt pincher of  claim 3 , wherein the elastic element is a torsional spring mounted on the pivotal element, one end of the elastic element urges against the bottom face of the base and its other end urges against the urging part on one side of the rotating arm, so that the rotating arm produces a resilient force toward the restricting rod. 
   
   
       6 . The belt pincher of  claim 1 , wherein one end of the belt pincher is penetrated with an axial rod to form a fixed end for the installation of a hook element, the other end thereof is formed with a penetrating end, the rotating arm is pivotally disposed between the two sidewalls with its one end and its other end is formed with the acting part, and the restricting rod is disposed opposite to the acting part of the rotating arm. 
   
   
       7 . The belt pincher of  claim 6 , wherein one end of the belt is inserted through the penetrating end and then winded around the acting part of the rotating arm, the end penetrates in between the acting part and the restricting rod, and the end goes out via the penetrating end again for hanging an object.
