摘要： A system for engagement and disengagement of carts to form a train of multiple carts. Each cart has a spring-loaded hitch that is held in a storage position when the carts are disengaged. A lever coupled to the hitch is operated to position the hitch for insertion into a receiver pocket of the next cart. A leading edge of the hitch deflects a spring-loaded lockpin. An angled guide member positions the hitch vertically within the pocket so that the lockpin comes into alignment with an aperture in the hitch. When aligned, the lockpin snaps into place and engages the aperture to lock the carts together. The close tolerance of the hitch within the pocket prevents transverse articulation of adjacent carts. Structures within the hitch and the pocket allow slight rotation in a longitudinal articulation axis about the lockpin and torsional articulation of the hitch within the pocket.
