Buckle for Fastening a Belt

Abstract

A buckle-belt assembly includes a buckle and a belt. The buckle includes two frames and a pivot. The first frame includes a crossbar, a sleeve extending parallel to the crossbar, and a tongue extending from the sleeve so that the tongue extends substantially parallel to a plane defined by the first frame. The second frame includes two lateral bars each formed with an eye and a crossbar formed between the lateral bars. The pivot is inserted in the sleeve and the eyes to pivotally connect the first frame to the second frame. The belt includes a first end connected to the crossbar of the first frame, a second end, and punch holes located near the second end.

1 . A buckle-belt assembly comprising:
 a buckle including:
 a first frame including a crossbar, a sleeve extending parallel to the crossbar, and a tongue extending from the sleeve so that the tongue extends substantially parallel to a plane defined by the first frame; 
 a second frame including two lateral bars each formed with an eye and a crossbar formed between the lateral bars; and 
 a pivot inserted in the sleeve and the eyes to pivotally connect the first frame to the second frame; and 
   a belt including a first end connected to the crossbar of the first frame, a second end, and punch holes located near the second end;   wherein the second end of the belt is passed through an opening defined by the second frame and the sleeve of the first frame as the tongue is inserted in a selected one of the punch holes;   wherein the first and second frames are located on two different sides of the pivot as the tongue is inserted in the selected punch hole so that the belt brings the tongue into tighter contact with the crossbar of the second frame as the tension in the belt is increased;   wherein the belt is tensioned as the second end of the belt is wound on the crossbar of the second frame and pulled away from the first frame in a direction substantially parallel to the tongue without the risk of prematurely inserting the tongue in any other punch hole than the selected punch hole.   
     
     
         2 . The buckle-belt assembly according to  claim 1 , further including a bushing rotationally placed on the crossbar of the second frame to avoid abrasion of the second end of the belt against the crossbar of the second frame. 
     
     
         3 . The buckle-belt assembly according to  claim 2 , wherein the bushing is made with an annular groove for receiving the tongue. 
     
     
         4 . The buckle-belt assembly according to  claim 1 , further including a bushing rotationally placed on the crossbar of the first frame to avoid abrasion of the first end of the belt against the crossbar of the first frame. 
     
     
         5 . The buckle-belt assembly according to  claim 1 , wherein the tongue extends substantially parallel to a plane defined by the first frame.
