Description

United States Patent [1 1 Morse July 2, 1974 [54] KNEE DESK 2,140,805 12/1938 Marseglia 248/444 [761 Inventor: Joseph Mom, ee Bay iilZiffi? 351323 2132???:33:3:iijiiijjiiijjiiiiiiijij..354325 Kaneohfi Oahu- Hawa" 96744 2,640,747 6/1953 Bodenhoff 248/444 PP 30 ,536 Primary Examiner-Bobby R. Gay

Assistant Examiner-William 'E. Lyddane [52] US. Cl. 108/43 51 1m. 01 A47b 23/00 [571 ABSTRACT [58] Field of Search 108/43, l8, 132; 248/444 A clip board has pivotally secured at one end a wire form shaped to the contour of a leg. The form, when [56] References Cited not in use, folds against the board. When in use the UNITED STATES PATENTS form folds out at an angle of about 90. 527,108 10/1894 Cooper 108/43 X 1 Claim, 3 Drawing Figures KNEE DESK SUMMARY OF THE INVENTION This invention provides a convenient flat writing surface for students or others wishing to take notes at meetings and other functions, which fits snugly over the knee and is held securely in place without slipping. The device is in the form of a clipboard to which is attached a wire form shaped to the contour of the leg, over which it fits.

The wire form folds flat on the bottom surface of the clipboard, out of the way when not used to support the board on the leg. In use, the plastic coated wire fits over the leg and the clipboard is positioned at the correct angle for maximum writing comfort. A lip or impression on the clipboard holds pens, pencils and other needs of the user. The school name, arithmetic and mathematical formulae or other data can be embossed on the clipboard.

There is a growing demand for a product such as this knee desk for use by students and others. It fills a longfelt need in a convenient, effective manner and at a cost within the budget of the ultimate user. Inherent advantages over possible competing items are available at minimal cost which should rapidly gain acceptance.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings: FIG. 1 is a perspective of my invention ready for use;

FIG. 2 is a side elevation of my invention in folded position; and

FIG. 3 is an inverted plan of the structure of FIG. 2.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A clip board 10 for supporting a pad 30 has a manually operable hold down clip 12. The clip 12 is controlled by spring 14 and is disposed at one end, and a pencil groove 16 is disposed transversely in the same surface at the other end.

A flexible wire form 18 shaped to accommodate a knee has opposite ends 20 extending transversely into openings 22 in opposite sides of the board. The bottom of the board has a groove 24 into which the form can be folded when the device is not in use. A rotatable clip 26 can hold the form in folded position.

In use, the clip is swung out of the way and the form is swung out at for use as described. The wire is flexible enough to expand or contract to fit various size legs. The form can be coated with a protective plastic outer layer.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

I claim:

1. In combination:

a clip board;

a knee receiving frame comprising a single length of plastic coated wire;

said wire having a central intumed loop to receive the knee;

said wire having opposite ends extending transversely into openings in opposite sides of the board and pivoted therein;

the bottom of the board having a groove shaped to receive the loop and central portion of the wire; said frame extending outward at right angles to the board 'when in use;

said frame being folded against the bottom of the board and fitting into said groove when not in use,

and held in the folded position by a rotatable clip.
