US4508306A — Computer read-out book stand

Claim 1

Independent Claim 269 words

A computer read-out stand comprising: (a) a generally rectangular base having a proximal end, a distal end and longitudinally extended sides connecting said ends, said sides including triangular extensions to receive a book support; (b) a generally rectangular adjustable book support having proximal and distal ends and longitudinal sides, said book support movably connected on its proximal end to said base's longitudinal sides proximate said sides' midpoints, said support including a bar attached at its ends, one each to each of said longitudinal sides and parallel to and approximate said proximal end; (c) at least one U-shaped book support elevator, each of said elevators' legs being rotatably attached to said base's distal end by a bar across open end of largest of said elevators, said elevators' bights being adapted to removably fit in a retaining means; (d) retaining means on said book support's distal end to receive and hold a bight of one of said elevators in position for use; (e) a pair of L-shaped posts attached to said book support, said posts' upright arms extending parallel to said book support's longitudinal sides, and said L's short arms attached at their ends to said support end and side intersections, so that said L's short arms form extensions of said support edges to provide receiving means for book spine holders; (f) at least one book spine holder adapted to slidably mount on said posts, whereby, when said retaining means is engaged, said book spine holder may be inserted into a book spine, and said holder may be slidably overfitted onto said posts, thereby supporting said book at a predetermined angle.

Claim 2

Dependent Claim 269 words

A computer read-out stand comprising: (a) a generally rectangular base having a proximal end, a distal end and longitudinally extended sides connecting said ends, said sides including triangular extensions to receive a book support; (b) a generally rectangular adjustable book support having proximal and distal ends and longitudinal sides, said book support movably connected on its proximal end to said base's longitudinal sides proximate said sides' midpoints, said support including a bar attached at its ends, one each to each of said longitudinal sides and parallel to and approximate said proximal end; (c) at least one U-shaped book support elevator, each of said elevators' legs being rotatably attached to said base's distal end by a bar across open end of largest of said elevators, said elevators' bights being adapted to removably fit in a retaining means; (d) retaining means on said book support's distal end to receive and hold a bight of one of said elevators in position for use; (e) a pair of L-shaped posts attached to said book support, said posts' upright arms extending parallel to said book support's longitudinal sides, and said L's short arms attached at their ends to said support end and side intersections, so that said L's short arms form extensions of said support edges to provide receiving means for book spine holders; (f) at least one book spine holder adapted to slidably mount on said posts, whereby, when said retaining means is engaged, said book spine holder may be inserted into a book spine, and said holder may be slidably overfitted onto said posts, thereby supporting said book at a predetermined angle.

Claim 3

Dependent Claim 28 words

The computer read-out stand according to claim 1 wherein said book spine holder includes slots at its ends sized to slidably overfit said L-shaped posts on said rack.

Claim 4

Dependent Claim 81 words

The book spine holder according to claim 1 wherein said holder comprises: (a) a flat bar pre-sized to extend slightly beyond the edges of a computer read-out book when said bar is placed inside said book proximate said spine of said book; (b) apertures proximate both ends of said bar to receive a binding cord of said book; and, (c) a pair of generally O-shaped extensions, one on each of said bar ends to slidably overfit said posts on said rack.

Claim 5

Dependent Claim 73 words

The book spine holder according to claim 1 wherein said holder comprises a first continuous rod forming an elongated rectangle, said rectangle being pre-sized lengthwise to overfit a cover of said book and sized transversely to slidably overfit said L-shaped posts, one elongated side of said rectangle having an additional second rod joined to its ends, said second rod running parallel to said side and forming a book cover-receiving slot with said side.

Claim 6

Dependent Claim 83 words

The book spine holder according to claim 1 wherein said holder comprises a pair of grooved latches, each sized at one end to slidably receive a track end of a predetermined binder book, said latches other end including a slot sized to slidably overfit said L-shaped post, said other end also including a hook so that when said latches are inserted into opposite ends of a binder book track, said book may be either fitted onto said stand or hung from said hooks.

Claim 7

Dependent Claim 212 words

The retaining means according to claim 1 wherein said means comprises: (a') a crossbar connecting said longitudinal sides of said book support, said crossbar located proximate said distal end of said book support and including apertures, one each proximate each of said crossbar's ends; (b') a pair of L-shaped braces, a first leg of each of said L attached to each of said book support's longitudinal sides between said crossbar and said book support's distal end, the other leg being attached to said retaining mean's crossbar between said aperture and said retaining mean's crossbar's midpoint, each of said first legs including an aperture aligned with said crossbar's aperture; (c') a U-shaped bar sized to fit through said retaining mean's crossbar's apertures and said brace's first leg's apertures, and having extended legs and a crosspiece joining said legs; (d') a spring circumscribing each of said U-bar's legs between said L-shaped brace and said retaining mean's crossbar, said spring including a movable spring stop at its end proximate said crossbar; and, (e') hooks attached to said retaining mean's crossbar, sized to overfit and retain said elevator's bight, so that when said elevator is raised, said elevator's bight is held in position by said hook and said extended legs of said retaining means U-shaped bar.

Claim 8

Dependent Claim 26 words

The book support elevators according to claim 1 wherein there are a plurality of elevators of graduated heights to provide angular elevation to said book support.

Claim 9

Dependent Claim 16 words

The computer read-out stand according to claim 1 wherein said base is constructed of cylindrical bars.

Claim 10

Dependent Claim 14 words

The book support elevator according to claim 1 wherein said elevators are cylindrical bars.

Claim 11

Dependent Claim 12 words

The posts according to claim 1 wherein said posts are flat bars.

Claim 12

Dependent Claim 43 words

The computer read-out stand according to claim 1 which includes, additionally, a bar parallel to and proximate said base's distal end, and fastened to said base's longitudinal side which acts as a stop for said elevators when said elevators are not in use.
