A shopping cart incorporating a removable skid attachment, 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 to give the cart stability and to facilitate movement through snow and over ice.

A shopping cart incorporating a removable skid attachment, to facilitate use of such cart in snow, which comprises a nestable supermarket shopping cart, nestable with other such carts by horizontal relative motion thereof, which cart includes a pair of front wheels, each of which is rotatable about a horizontal axis which is transverse to the longitudinal 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 rotable about a horizontal transverse axis in a vertical plane parallel to the longitudinal axis of the cart, a removable skid attachment which includes a pair of skid members, each of which is substantially C-shaped, which members are simultaneously movable into inoperative and into operative skid positions, as desired, with respect to the shopping cart, so that when the skid members are in operative position 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, with the open ends of the C\s being up, and so that when the skid members are in inoperative position, which is a retracted or storage position, they are above the bottoms of the front wheels, inside such wheels and subtantially horizontal, and combination mounting and positioning means, for selectively holding the pair of skid members in operative and inoperative positions on a shopping cart near the front wheels thereof and away from the back wheels thereof and for moving the pair of skid members between operative and inoperative positions, with the C\s passing under the front wheels during such movements, which shopping cart-skid attachment combination is nestable with other such combination apparatuses when the skid attachments thereof are in inoperative positions.
