Abstract
Abstract A shopping cart clipboard adapted to be attached to various conventional shopping carts, and being movable between a horizontal working position and a vertical stored position. The clipboard includes a planar surface that carries a spring biased clip to secure materials on the surface. The planar surface is part of a clipboard assembly that is attached to a cart bracket by engagement of a portion of the clipboard assembly in an elongated slot formed in the bracket. This structure allows selective movement of the clipboard between the working position and the stored position, while providing for locking the clipboard assembly from removal from the bracket after the bracket is attached to the shopping cart.

Claim 1
Independent Claim
183 words
A clipboard in combination with a shopping cart, the improvement comprising: a cart bracket including a vertical plate attached to said shopping cart and disposed to extend upwardly therefrom, a horizontal plate extending from the top of said vertical plate, and an elongated slot formed in said horizontal plate near the juncture of said vertical plate and said horizontal plate; a clipboard assembly including: a planar surface having a biased clip attached thereto, a support section extending generally normal to said planar surface, a return section extending generally normal to said support section and being disposed generally parallel to said planar surface, and a locking section extending from said return section toward said planar surface and terminating in spaced relationship thereto, said clipboard assembly being selectively attached to said bracket by extending said locking section, said return section, and said support section through said slot; said planar surface being relatively movable between a horizontal working position wherein said support section engages the vertical plate of the bracket, and a vertical stored position wherein said support section engages the horizontal plate of the bracket.
Claim 2
Dependent Claim
183 words
A clipboard in combination with a shopping cart, the improvement comprising: a cart bracket including a vertical plate attached to said shopping cart and disposed to extend upwardly therefrom, a horizontal plate extending from the top of said vertical plate, and an elongated slot formed in said horizontal plate near the juncture of said vertical plate and said horizontal plate; a clipboard assembly including: a planar surface having a biased clip attached thereto, a support section extending generally normal to said planar surface, a return section extending generally normal to said support section and being disposed generally parallel to said planar surface, and a locking section extending from said return section toward said planar surface and terminating in spaced relationship thereto, said clipboard assembly being selectively attached to said bracket by extending said locking section, said return section, and said support section through said slot; said planar surface being relatively movable between a horizontal working position wherein said support section engages the vertical plate of the bracket, and a vertical stored position wherein said support section engages the horizontal plate of the bracket.
Claim 3
Dependent Claim
79 words
The clipboard of claim 1 wherein said locking section is disposed to move into and out of said slot only when said planar surface is positioned in near proximity to the vertical plate of said bracket, thereby locking said clipboard assembly into engagement with said cart bracket when the bracket is attached to a shopping cart wherein the shopping cart is disposed between said bracket and said planar surface when the planar surface is in the vertical stored position.
Claim 4
Dependent Claim
41 words
The clipboard of claim 1 wherein said shopping cart includes a horizontally disposed rail and wherein said vertical plate of said cart bracket includes an offset section disposed to contact said horizontal rail thereby supporting said bracket against downward vertical movement.
Claim 5
Dependent Claim
