Abstract
A crossbar and article carrier are provided, the crossbar having stanchions at each end thereof. Each stanchion has a first jaw member affixed thereto and a second jaw member pivotally coupled thereto. The second jaw member includes a thumbwheel and stem, the stem having a cam follower surface thereon. The stanchion includes a ramped surface with a detent for receiving and locking the cam when the thumbwheel is rotated. In this manner, the crossbar may be detachably mounted to the longitudinal side rails. The design and location of the jaws and thumbwheel provide for easy attachment and detachment of the crossbar rail. The design of the second jaw member further provides mechanical advantage for clamping the first and second jaw members over a lip protruding from the side rails.
