Abstract
Abstract A device for use with a shopping cart to provide a portable worktable includes a flat table member supportable by the sides of the cart and positionable to substantially cover the open top of a shopping cart, and a plurality of legs for removably retaining the table member on the cart. The legs includes a pair of rear and a front retaining member depending from the bottom of the table member. The stop members are disposed in spaced relation to one another and are engagable with the sides of the cart to prevent width-wise shifting of the table. The front retaining member includes a channel-shaped opening that receives the upper rail of the front of the cart to prevent length-wise shifting of the table.

Claim 1
Independent Claim
243 words
A device for use with a shopping cart to provide a portable worktable, comprising: a flat table member having a planar work surface supportable by the side and front walls of a shopping cart, said table member having a width and length sufficient to substantially cover the open top of a cart; and means on said table member for removably retaining said table member on a cart, said retaining means includes a pair of stop members engageable with the walls of a shopping cart which depend from the undersurface of said table member and are in spaced relation to one another adjacent opposite side edges of said table member, said stop members being positioned to butt against the side walls of a cart to prevent widthwise shifting of said table member when the table member is positioned on a cart and further includes a retaining member which depends from the undersurface of said table member adjacent its front edge and is engageable with the front wall of a shopping cart, said retaining member includes a channel-shaped opening extending widthwise of said table member for receiving the upper end of the front wall of the cart to prevent lengthwise shifting of said table member when the table member is positioned on a cart, said channel-shaped opening being spaced from the undersurface of said table member to elevate the front of said table member so that said work surface is in a substantially horizontal position.
