Buckle

Abstract

A buckle for connecting two belt-like members includes a pair of side frame portions; a first cross bar extending between the side frame portions; a second cross bar extending between the side frame portions and disposed between the first cross bar and end portions of the side frame portions; and a finger hooking portion formed in a tongue shape projecting from the second cross bar toward the end portions of the side frame portions. One of the two belt-like members is inserted between the side frame portions from a back side of the buckle, and is taken out to a front side of the buckle. Then, the one belt-like member passes between the first cross bar and the second cross bar to the back side of the buckle.

1 . A buckle for connecting two belt-like members, comprising: 
 a pair of side frame portions having end portions;    a first cross bar extending between the pair of the side frame portions;    a second cross bar extending between the pair of the side frame portions and disposed between the first cross bar and the end portions of the side frame portions; and    a finger hooking plate portion formed in a tongue shape and projecting from the second cross bar toward an end side of the end portions of the side frame portions, said finger hooking plate portion having side end portions attached to the side frame portions and located away from the end portions of the side frame portions.    
   
   
       2 . A buckle according to  claim 1 , wherein said first and second cross bars are arranged such that one of the two belt-like members is inserted between the pair of the side frame portions from a back side of the buckle to a front side of the buckle and passes through a space between the first cross bar and the second cross bar to the back side of the buckle to wind around the first cross bar, and when the finger hooking plate portion is lifted up from the back side of the buckle, the belt-like member tightened by the buckle is released to allow the belt-like member to slide with respect to the first cross bar.  
   
   
       3 . A buckle according to  claim 1 , wherein said plate edge portion of the finger hooking plate portion has a mountain shape such that a central portion of the finger hooking plate portion projects forward.  
   
   
       4 . A buckle according to,  claim 1 , wherein said side frame portions include upper and lower surfaces positioned outside upper and lower surfaces of the finger hooking plate portion on the front side and back side of the buckle, respectively.  
   
   
       5 . A buckle according to  claim 1 , wherein said end portions of the side frame portions are always positioned at a substantially same position or away from the side end portions of the finger hooking plate portion.  
   
   
       6 . A buckle according to  claim 2 , further comprising at least one third cross bar attached to the side frame portions at a side opposite to the second cross bar relative to the first cross bar for connecting another belt-like member.  
   
   
       7 . A buckle according to  claim 1 , wherein said second cross bar is integrally formed with the finger hooking plate portion.
