Rucksack rapid attachment buckle

Abstract

A buckle used to attach a rucksack to a frame using a strap. The buckle includes a housing, having a bottom, two side walls and an opening in the upper portion thereof. The side walls are parallel for about one half the length of the housing before diverging to form a Y-shaped opening. The side walls have retaining flanges adapted to receive and guide a strap which is locked in the buckle, wherein the diverging side walls form a jamming socket to retain the strap and attach the rucksack to the frame.

What is claimed is:  
     
         1 . A buckle, said buckle comprising: a housing, said housing having a bottom, two side walls and an opening in the upper portion thereof, said side walls being parallel for about one half the length of the housing before diverging to form a Y-shaped opening, said side walls being retaining flanges are adapted to receive and guide a strap which locks within the buckle, wherein the diverging side walls form a jamming socket to retain a tab formed at an end of the strap.  
     
     
         2 . The buckle of  claim 1 , wherein said jamming socket includes a jam surface.  
     
     
         3 . The buckle of  claim 1 , wherein said jamming socket includes a stop surface.  
     
     
         4 . The buckle of  claim 1 , wherein said jamming socket includes and a pinch radius.  
     
     
         5 . The buckle of  claim 1 , wherein the side walls include over-arching lips.  
     
     
         6 . The buckle of  claim 1 , wherein the retaining flanges are beveled at a 45-degree angle on their bottom or internal edges.  
     
     
         7 . The buckle of  claim 1 , wherein the strap has a multiple folded end tab.  
     
     
         8 . A buckle used to attach a rucksack to a frame using a strap, said buckle comprising: a housing, said housing having a bottom, two side walls and an opening in the upper portion thereof, said side walls being parallel for about one half the length of the housing before diverging to form a Y-shaped opening, said side walls being retaining flanges adapted to receive and guide a strap which is locked in the buckle, wherein the diverging side walls form a jamming socket to retain the strap such that the rucksack is attached to the frame.  
     
     
         9 . The buckle of  claim 8 , wherein said jamming socket includes a jam surface.  
     
     
         10 . The buckle of  claim 8 , wherein said jamming socket includes a stop surface.  
     
     
         11 . The buckle of  claim 8 , wherein said jamming socket includes a pinch radius.  
     
     
         12 . The buckle of  claim 8 , wherein the retaining flanges are beveled at a 45-degree angle on their bottom or internal edges.  
     
     
         13 . The buckle of  claim 8 , wherein the strap has a multiple folded end tab.  
     
     
         14 . The buckle of  claim 8 , wherein the end of the strap is attached to a wedge to form a tab.  
     
     
         15 . The buckle of  claim 8 , wherein the tensile loading on the strap at the jamming socket compresses the tab against itself, and significantly increases its ability to resist failure due to the tab pulling apart.  
     
     
         16 . The buckle of  claim 8 , wherein a mounting strap mounts the buckle to a substrate and an attaching strap locks in the buckle.
