Abstract:
A bike carrier on a drawbar for a trailer hitch receiver has two trays for the wheels of a bike. The trays pivot between an operational lateral position and a compact forward position for shipping and storage. A tray lock bar mounted in the carrier is urged by a spring into a position that automatically releasably locks the trays in the operational position. Pivoting wheel retention arms on the trays have cross members that contact the bike tires and are adjustable along the retention arms for different wheel diameters. Each cross member is held against a tire by a retention arm pivot ratchet that is releasable to allow the retention arms to pivot outward to release the bike from the carrier.

Claim (Index 6):
The bike carrier of  claim 4 , further comprising:\n an H-shaped or inverted U-shaped wheel retention arm pivotally attached to a distal end of each of the trays, each wheel retention arm comprising two parallel side arms and a cross member between them; wherein each wheel retention arm pivots inward until the cross member thereof contacts a respective tire of the bike at a point above a wheel axle thereof, and the wheel retention arm is fixed against the tire by a ratchet mechanism, causing the tires of the bike to be bracketed between the retention arms, such that the bike is secured in all directions by the tires held between the trays and the cross members of the retention arms; wherein the ratchet mechanism comprises: a linear ratchet bar mounted on a side of the tray; a pawl slidably mounted on the ratchet bar; a finger on each pawl that jams against a bottom side of the ratchet bar and stops the pawl when the pawl attempts to slide distally on the ratchet bar, but allows the pawl to slide proximally on the ratchet bar; and a manual release lever on the pawl that pivots the pawl in a release direction that moves the finger away from the bottom side of the ratchet bar, allowing the pawl to slide distally along the ratchet bar, releasing the retention arm from the tire; wherein, when the pawl is pivoted by the release lever, a stop bar on the pawl contacts a top side of the ratchet bar and prevents over-rotating the pawl in the release direction to a position that would drag the pawl on the ratchet bar in the release direction.
