Abstract
Abstract The apparatus comprises a post having a floor-engaging base, an arm having its rear end pivotally connected to the top of said post for horizontal swinging movement, a connector pivoted to the front end of the arm for rotation about a vertical axis, said connector defining a rearwardly- upwardly-inclined plate-like element having upwardly-converging side edges which are also rearwardly converging thicknesswise of the plate-like element. A reading material support plate, having a bottom ledge, is provided at its back face with a pair of flat, elongated retainer elements which define between themselves a series of cavities with upwardly-converging side edges, which are also rearwardly converging thicknesswise for mating with and selectively receiving the plate-like element of the connector. It is a simple matter to insert the plate-like element in a selected cavity. The support plate is thus supported at a selected level and prevented from detachment from the connector. The apparatus is more particularly adapted to support a book or the like in reading position for a person seated in a chair.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A reading apparatus comprising a post, an arm having a rear end pivotally connected to an upper portion of said post for substantially horizontal swinging movement about the longitudinal axis of said post, said arm having a front end, a connector pivoted to the front end of said arm for rotation of said connector relative to said arm about a second axis substantially parallel to said longitudinal axis, said connector defining a plate-like element rearwardly upwardly inclined relative to said second axis and having upwardly-converging side edges, and a support for reading material including a support plate having a front face and a back face, a top edge and a bottom edge, a ledge protruding from said bottom edge at said front face, a series of superposed cavities formed at said back face, extending between said top and bottom edges, each cavity having upwardly-converging sides for selectively mating with the converging sides of said plate-like element whereby said plate-like element, when inserted in a selected cavity, will support said support plate at a selected level, and further including retainer means at each cavity engageable with said connector to releasably prevent detachment of said support from said connector.
Claim 2
Dependent Claim
197 words
A reading apparatus comprising a post, an arm having a rear end pivotally connected to an upper portion of said post for substantially horizontal swinging movement about the longitudinal axis of said post, said arm having a front end, a connector pivoted to the front end of said arm for rotation of said connector relative to said arm about a second axis substantially parallel to said longitudinal axis, said connector defining a plate-like element rearwardly upwardly inclined relative to said second axis and having upwardly-converging side edges, and a support for reading material including a support plate having a front face and a back face, a top edge and a bottom edge, a ledge protruding from said bottom edge at said front face, a series of superposed cavities formed at said back face, extending between said top and bottom edges, each cavity having upwardly-converging sides for selectively mating with the converging sides of said plate-like element whereby said plate-like element, when inserted in a selected cavity, will support said support plate at a selected level, and further including retainer means at each cavity engageable with said connector to releasably prevent detachment of said support from said connector.
Claim 3
Dependent Claim
64 words
A reading apparatus as defined in claim 1, wherein said cavities are defined by a pair of flat, elongated retainer elements fixed to and rearwardly protruding from said rear face of said support plate, extending between said top and bottom edges and transversely spaced from each other, each retainer element having a series of inward side portions which define the sides of said cavities.
Claim 4
Dependent Claim
57 words
A reading apparatus as defined in claim 2, wherein said upwardly-converging side edges of said plate-like element are also rearwardly converging thicknesswise of said plate-like element; and wherein said retainer means are formed by said inward side edge portions of said retainer elements converging thicknesswise away from said rear face and selectively mating with said plate-like element.
Claim 5
Dependent Claim
55 words
A reading apparatus as defined in claim 3, wherein each said retainer element has an integral bottom extension extending rearwardly from said support plate at substantially the level of said ledge and forming an acute angle with said back face to stand said support on a horizontal surface with said support plate rearwardly, upwardly inclined.
Claim 6
Dependent Claim
40 words
A reading apparatus as defined in claim 4, wherein said arm comprises at least two sections pivotally interconnected intermediate said front and said rear end of said arm, about a pivotal axis which is substantially parallel to said longitudinal axis.
Claim 7
Dependent Claim
91 words
A reading apparatus as defined in claim 4, wherein each inward side edge portion of each retainer element is separated from an adjacent inward side edge portion by a transverse step, each step spaced downwardly from the bottom of said plate-like element when said plate-like element is inserted in operative position within a selected cavity, so that said plate-like element can be removed from said selected cavity by first upward movement of said support plate relative to said connector and then frontward movement of said support plate relative to said connector.
