A skid attachment for a shopping cart, useful in operative position to allow easy movement of the cart over snowy and icy surfaces, as in supermarket parking lots, includes a pair of skid members near the front wheels of the cart, when the attachment is installed, which are selectively movable into inoperative storage position underneath the cart and into operative position with the skid surfaces thereof being lower than the front wheels of the cart, hand operable linkages for moving the skid members selectively into either inoperative or operative position, and fastening means for holding the skid members and the associated linkages to the cart. Preferably, the skid attachment includes stops for limiting the movements of the skid members, locking means for holding them in position and handle or equivalent means so that the skid members may be readily moved into desired positions. Additionally, the skids are of preferred shapes, such as skids, runners or skiis, to give the cart stability and to facilitate movement through snow and over ice. Also disclosed is a method of facilitating movement of the skid portion of the skid attachment between inoperative and operative positions by raising the cart with a certain type of lifting device so that the weight of the filled cart does not oppose movements of the skids, which, in such movements, have portions thereof passing beneath the front wheels of the cart.

A shopping cart incorporating a removable attachment to facilitate use of such cart in snow, which comprises a nestable supermarket shopping cart, nestable with other such carts by relative horizontal motion thereof, which cart includes a pair of front wheels, each of which is rotatable about a horizontal axis which is transverse to the longtiudinal axis of the shopping cart when the cart is being moved forwardly, and which wheels are movable about a vertical axis, and a pair of rear wheels, each of which is rotatable only about a horizontal transverse axis in a vertical plane parallel to the longitudinal axis of the cart, a removable skid, runner or ski attachment which includes a pair of cart supporting skids, runners or skiis, which are simultaneously movable into inoperative and into operative positions, as desired, with respect to the shopping cart, so that when such cart supporting members are in operative positions they are below the shopping cart front wheels and alongside and outside of such wheels, bearing the weight of the cart instead of the front wheels bearing such weight, and so that when such members are in inoperative positions, which are retracted or storage positions, they are above the bottoms of the shopping cart front wheels, inside such wheels and substantially horizontal, and combination mounting and positioning means for selectively holding the pair of cart supporting members in operative or inoperative positions on the shopping cart and near the front wheels thereof and away from the back wheels thereof and for moving the pair of such members between operative and inoperative positions, during which movements the members pass under the shopping cart front wheels, which shopping cart-attachment combination is nestable with other such combinations when the attachments thereof are in inoperative positions.
