ABSTRACT:
A buckle fitting that can tension with leverage, lengths of belt or webbing. The buckle will lock the belt at any point along its length until freed by a quick release mechanism. The buckle consists of two u-sections pivotably connected at one end to allow a hinge action of the longer upper section about the lower section. A spring loaded cam with a limited movement, rocks away from the surface of the lower section to allow belt to move forward and moves closer to the surface of the lower section to prevent belt moving backwards. A cylindrical roller locates across the lower section between the cam and the hinged join. A slot in the upper section allows belt to pass through when the upper section is closed over the lower section. When the upper section is levered in an arc about the lower section the relative aspect of the slot alters enabling belt to be caught and pulled further through the cam in the lower section. Repeating this action further advances the belt through the buckle. The locking cam can be overriden manually in order to release the tensioned belt.
