Abstract
Abstract There is disclosed a document holder having a clip to secure one or several pages of a document, supporting the pages in a convenient position adjacent a computer keyboard, typewriter, and the like. The document holder has a universal base which is formed of first and second angle members that are joined along their vertical surfaces to form a channel. The horizontal sides are grooved their entire length and receive a coextensive relatively stiff but resilient strap. Each of the straps receives a continuous band of an elastic and resilient cushion that is coextensive its length. The angle members are joined with screw fasteners extending through aligned apertures in the vertical sides of the angles with the apertures of at least one of the angle members being elongated to provide adjustability in the width of the assembled channel of the base. The document clip is supported on an arm that is pivotally secured to the back side of the assembled channel by an angle bracket that is pivotally mounted to the channel thereby permitting the arm to be moved freely through a plane that is normal to the plane of the keyboard which is received within the channel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
288 words
A document holder to support documents above a computer keyboard having a triangular cross section with a thick rear edge, narrow front edge and inclined top surface, which comprises: a. an adjustable base formed from a pair of elongated angles having vertical and horizontal sides, with their vertical sides joined together to form an elongated channel which is received over the rear edge of said computer keyboard and which has a length to extend along the length of said computer keyboard, said angles being secured by assembly means comprising fasteners extending through apertures in said vertical sides with at least one of each pair of aligned apertures being elongated to provide adjustability in the width of said channel to accommodate variations in sizes of computer keyboards, and slots along the horizontal sides of each of said angles and received in each slot a stiff but yielding sheet extending outwardly from said slot and supporting a cushion band coextensive the length of each sheet to apply compressive attachment forces to the bottom and inclined top surface of said computer keyboard; b. an angle bracket with one of its legs rotationally mounted on the backs of the joined vertical sides of said angles; c. an elongated arm having a length substantially the same as said length of said elongated channel with one end thereof mounted to the other leg of said angle bracket; d. a spring clip pivotally mounted to the opposite end of said elongated arm, with said angle bracket and spring clip being pivotal about axes normal to the joined vertical sides of said angles, whereby said elongated arm can be pivoted upwardly from the rear of said elongated channel to support a document above said computer keyboard.
