Support belt and buckle

Abstract

A support belt and buckle has a rotatable member on buckle cross bar; and a pair of cam surfaces along the rotatable member and diametrically situated thereon, wherein faces of the rotatable member extending between the cam surfaces are flat. The belt may have an elastic material, the elastic material secured to a first position on the belt and the elastic material extending lengthwise on the belt and the elastic material secured to a second position on the belt, wherein the elastic material is more elastic than the belt.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:  
     
         1 . A support belt and buckle comprising: 
 a belt extending lengthwise and having a first and second end;    an apertured frame having opposed forward and rearward transverse members connected by side members;    said rearward transverse member being secured to said first end of said belt; said second end of said belt adapted to pass through said frame;    a cross bar on said side members and movable towards and away from said forward transverse member;    a rotatable member on said cross bar; and    a pair of cam surfaces along said rotatable member and diametrically situated thereon; wherein a face of said rotatable member extending between said cam surfaces is a flat face.    
     
     
         2 . A support belt and buckle as claimed in  claim 1 , wherein both faces of said rotatable member extending between said cam surfaces have flat faces.  
     
     
         3 . A support belt and buckle of  claim 1  or  claim 2 , further comprising an elastic material, said elastic material secured to a first position on said belt and said elastic material extending lengthwise on said belt and said elastic material secured to a second position on said belt, wherein said elastic material is more elastic than said belt.  
     
     
         4 . A support belt and buckle comprising: 
 a belt extending lengthwise;    a buckle for adjustably tightening said belt; and    an elastic material, said elastic material secured to a first position on said belt and said elastic material extending lengthwise on said belt and said elastic material secured to a second position on said belt;    wherein said elastic material is more elastic than said belt.    
     
     
         5 . A support belt and buckle as claimed in  claim 4 , wherein said elastic material has a shorter length than the length of the portion of said belt as measured between said first position and said second position.
