Abstract:
1. A weight bar clamp, comprising: a collar comprising two opposing walls extending from a common end, each of the two opposing walls comprising an arced interior surface extending partially about a collar center axis and terminating adjacent each other at a terminating wall end of each wall, wherein a biasing member biases the terminating ends of each wall away from each other; at least two structural ribs on each of the two opposing walls, each structural rib extending in an arc partially between the common end and the terminating end of a respective wall of the two opposing walls, wherein the ribs on each respective wall are spaced from respective side ends of the wall, concentric to a common arc axis particular to that respective wall, and the common arcs for each of the two opposing walls are parallel with the collar center axis; two cam halves, each one of the two cam halves coupled to the terminating end of one of the two opposing walls, each of the two cam halves comprising an upper lip separate from the upper lip of the other of the two cam halves and extending outward from the respective cam half; a handle comprising a cam opening with a ledge extending at least partially around the cam opening and engaging the upper lip of the two cam halves, the handle pivotally coupled to the two cam halves, wherein the cam halves extend into the cam opening such that when the handle is in a first position the biasing member causes the cam halves to separate from each other and in a second position the handle pushes the cam halves toward each other counter to the biasing member's bias.
