Abstract: An adjustable article carrier track mount system that compensates for the cross-line radius or fall-away slope of a vehicle roof and easily and effectively locks the adjustable article carrier in place, has an elongated track, an end support operably connected to the track and adapted to slidably receive a crossbar, to slide longitudinally along the track, and rotate about the longitudinal axis of the track. To facilitate locking the adjustable article carrier in place, the track mount system includes a locking mechanism that is slidably received in the track and operably connected to the end support. The locking mechanism includes opposed wedges and a device adapted to force one of the wedges against another wedge to lock the locking mechanism within the track and thus the end support at a desired position along the track.

Abstract: A sliding carrier comprising a frame and a sled, with the frame being mounted to the rooftop of a vehicle, and the sled adaptable for carrying certain objects being in sliding communication with the frame. The sled unlocks and slides out of the frame to a rearmost horizontal deployment position. The sled releases from the horizontal plane of travel into a pivoting plane of travel by lifting and pulling the sled over a stop block. The sled then pivots about a rearward wheel assembly until a landing gear assembly contacts the ground. A winch assembly is then used to control the further lowering of the sled from a grounded position to a loading position, at which time certain objects may be loaded onto the sled. The sled is returned to a locked traveling position atop the vehicle by reversing the steps above.
