Strap adjuster

Abstract

A strap adjuster has a quadrangular frame; a plurality of slots defined in the frame to extend in a transverse direction such that a strap can be fitted through the slots; and at least one support bar formed between the slots, wherein recessions are formed on both widthwise side surfaces, respectively, of the frame such that the frame can be easily grasped using fingers.

1 . A strap adjuster comprising:
 a quadrangular frame;   a plurality of slots defined in the frame to extend in a transverse direction such that a strap can be fitted through the slots; and   at least one support bar formed between the slots,   wherein recessions are formed on both widthwise side surfaces, respectively, of the frame such that the frame can be easily grasped using fingers.   
   
   
       2 . The strap adjuster according to  claim 1 , wherein inclined surfaces are formed on an upper surface of the frame to extend from a center portion of the frame adjoining the slots toward side surfaces of the frame. 
   
   
       3 . The strap adjuster according to  claim 2 , wherein distal ends of the inclined surfaces, which are formed in a direction parallel to an extending direction of the strap, extend further outward in such a way as to define close contact parts. 
   
   
       4 . The strap adjuster according to  claim 1 , wherein an auxiliary frame is formed on one widthwise side or each of both widthwise sides of the frame in such a way as to define a slot between the auxiliary frame and the frame so that a strap can be fitted through the slot. 
   
   
       5 . The strap adjuster according to  claim 4 , wherein a recession is formed on a widthwise side surface of the auxiliary frame. 
   
   
       6 . The strap adjuster according to  claim 5 , wherein a lower surface of the frame is formed as a rounded surface to be concentric in a lengthwise direction of the frame, and a lower surface of the auxiliary frame is also formed as a rounded surface to be concentric in the lengthwise direction of the frame.
