Abstract

See full text

A shopping cart conveyor system that moves a shopping cart from one location to another along a path. The system includes a frame, a track coupled to the frame, and a conveyor coupled to the frame and having an engagement member (e.g., multiple engagement members) adapted to engage a shopping cart. The engagement member is movable (e.g., pivotable) relative to the track from a first position, where the engagement member will engage and move the shopping cart along the path, and a second position, where the engagement member is capable of releasing engagement of the shopping cart. Preferably, the engagement member is biased toward the first position (e.g., by a resilient member). In one embodiment, the engagement member includes an engagement surface adapted to engage the shopping cart and defining an engagement angle between the engagement surface and a reference axis parallel to the path. In this embodiment, the engagement angle is acute when the engagement member is in the first position and is obtuse when the engagement member is in the second position.
