Abstract:
1. A cam buckle configured to reduce friction for tightening a strap, the cam buckle comprising: a frame; a brake member at having a contoured friction surface, said brake member being rotatably coupled to said frame and pivotal about a first axis, and including a brake roller having unidirectional rotation; a roller member rotatably coupled to said frame about a second axis, said second axis being substantially parallel said first axis; a biasing element operable to bias said brake member toward said roller member and against the strap; and a webbed strap operable to be biased between said contoured friction surface and said roller member so that said brake member urges said webbed strap against said roller member when placed in tension so as to maintain said tension by preventing movement of said webbed strap in one direction and allowing movement in a second direction to increase said tension; wherein said roller member and said brake roller are operable to rotate with movement of said webbed strap in said second direction to increase said tension in said webbed strap.
