Abstract
A cart designed to carry small to intermediate volumes of products, to be easier to maneuver than existing, full-scale shopping carts, to consume less space, both during use and when in a storage configuration, and, due to convenience and ease of use, to encourage use by customers who would otherwise avoid using any shopping cart at all. The cart provides upper and lower baskets which, as coordinated through linkage rods, move in concert between a lowered, useable configuration and a raised, storage configuration.
Claims1
A shopping cart comprising:
- an elongate support frame having a handle at an upper end and a subframe pivotally attached at a rearward end to a lower end of the elongate support frame;
- an upper basket member;
- a lower basket member;
- said upper basket member being pivotally attached to said support frame at an attachment point along said elongate support frame;
- said lower basket member being fixedly attached to said subframe and spaced apart from said upper basket member point;
- linkage means attached at opposite linkage means ends to said upper and lower baskets whereby rotational movement of one of said upper and lower baskets about attachment points to said elongate support frame effects a corresponding rotational movement of said other upper and lower basket between extended and retracted positions;
- and
- a pair of ground engaging wheels rotatably attached to the lower end of said elongate support frame, at least one wheel rotatably attached to a forward end of said subframe for ground engagement when the basket members are pivoted to their extended position, and at least one wheel rotatably attached to a rearward end of said lower basket member for ground engagement when the basket members are pivoted to their retracted position .
