US Patent 10086769 Bike carrying folding tray assembly with automatic tray lock

A bike carrier for a trailer hitch receiver with two trays that pivot between a laterally opposed operational position for holding the wheels of a bike and a forward folded position for compact shipping and storage. In the operational position a tray open lock plate rises under spring force between the inner ends of the trays, stopping the trays from pivoting forward. Other stops on the carrier prevent backward pivoting of the trays. Pushing the plate down allows the trays to pivot forward. A tray folding stop plate may stop the trays from over-rotating forward past a parallel position when folding.
