Abstract

Abstract A portable book stand for supporting an open book or other reading material includes a base member comprising a base panel and a front panel extending upwardly from one edge thereof at an acute angular relationship thereto. A support member includes a support panel and a bottom panel extending from one edge thereof an an oblique angular relationship thereto. A slot extends through the support panel of the support member directly adjacent to the bottom panel, the slot being dimensioned to receive the base panel of the base member therethrough in slidable fashion. Thusly assembled, the bottom panel and the base panel rest atop a supporting surface, and the front panel and support panel of the support panel are disposed generally parallel and spaced apart so that the lower edge of an open book may be retained on said base panel between the front panel and the support panel, the spine of the book inclined against and supported by the support panel. The spacing of the front panel and the support panel may be adjusted by the selective amount of insertion of the base panel through the slot. At least the front panel is formed of transparent material so that the book portion disposed behind the front panel is visible to the reader. The base member and support member may be formed entirely of transparent plastic or resin material. With the base member and support member separated, the base panel and support panel may be disposed to impinge on the front and back covers of a book, and secured thereabout by an elastic, band, so that the two members form a protective enclosure for the book while being carried therewith. Alternatively, one of the members may be inserted between the pages of a book as a page marker, and the other member secured to an outer cover of the book.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 141 words
A portable book stand for supporting an open book including base means for engaging a horizontal surface, support means releasably secured to said base means and upwardly extending therefrom to support and display a book inclined against said support means, means for separating and reconfiguring said support means and base means as a protective enclosure to be secured about a book, said base means including a base member, said base member including a base panel adapted to impinge on the horizontal surface, said base member further including a front panel extending from one edge of said base panel and defining an acute angle therewith, said front panel including an upper edge having a pair of rounded lobes extending generally upwardly therefrom and spaced apart laterally to engage lower edge portions of opposed pages of an open book supported by said stand.
Claim 2
Dependent Claim 141 words
A portable book stand for supporting an open book including base means for engaging a horizontal surface, support means releasably secured to said base means and upwardly extending therefrom to support and display a book inclined against said support means, means for separating and reconfiguring said support means and base means as a protective enclosure to be secured about a book, said base means including a base member, said base member including a base panel adapted to impinge on the horizontal surface, said base member further including a front panel extending from one edge of said base panel and defining an acute angle therewith, said front panel including an upper edge having a pair of rounded lobes extending generally upwardly therefrom and spaced apart laterally to engage lower edge portions of opposed pages of an open book supported by said stand.
Claim 3
Dependent Claim 16 words
The book stand of claim 1, wherein said front panel is formed of a transparent material.
Claim 4
Dependent Claim 20 words
The book stand of claim 1, wherein said base member and said support means are formed of transparent, form-retaining material.
Claim 5
Dependent Claim 256 words
A stand for supporting reading material, comprising a base member having a base panel adapted to impinge on a horizontal surface and a front panel extending from one edge of said base panel and defining an oblique angle therewith, a support member having a support panel extending upwardly from the horizontal surface and a bottom panel extending from a lower edge of said support panel and defining an oblique angle therewith, slot means in said support member for receiving therethrough a portion of said base panel in slidable fashion, said front panel and said support panel oriented in generally parallel, spaced apart disposition to retain reading material therebetween, the reading material inclined against said support panel and supported thereby, wherein said front panel and said support panel are disposed in adjustably variable spacing according to the extent to which said portion of said base panel is inserted through said slot means, further including means for separating and reconfiguring said support means and base means from an in-use position to a protective enclosure to be secured about a book by removing said base panel from said slot means, wherein said support panel is disposed to impinge on one outer cover of a closed book, and said base panel is disposed to impinge on the other outer cover of the closed book, said front panel and said bottom panel disposed adjacent to sides of the closed book in protective fashion, and means for securing said support means and said base means as said protective enclosure about the book.
Claim 6
Dependent Claim 256 words
A stand for supporting reading material, comprising a base member having a base panel adapted to impinge on a horizontal surface and a front panel extending from one edge of said base panel and defining an oblique angle therewith, a support member having a support panel extending upwardly from the horizontal surface and a bottom panel extending from a lower edge of said support panel and defining an oblique angle therewith, slot means in said support member for receiving therethrough a portion of said base panel in slidable fashion, said front panel and said support panel oriented in generally parallel, spaced apart disposition to retain reading material therebetween, the reading material inclined against said support panel and supported thereby, wherein said front panel and said support panel are disposed in adjustably variable spacing according to the extent to which said portion of said base panel is inserted through said slot means, further including means for separating and reconfiguring said support means and base means from an in-use position to a protective enclosure to be secured about a book by removing said base panel from said slot means, wherein said support panel is disposed to impinge on one outer cover of a closed book, and said base panel is disposed to impinge on the other outer cover of the closed book, said front panel and said bottom panel disposed adjacent to sides of the closed book in protective fashion, and means for securing said support means and said base means as said protective enclosure about the book.
Claim 7
Dependent Claim 23 words
The book stand of claim 4, wherein said front panel includes a pair of laterally spaced lobes at a distal upper edge thereof.
Claim 8
Dependent Claim 42 words
The stand of claim 4, wherein said front panel includes an upper edge having a pair of lobes extending generally upwardly therefrom and spaced apart laterally to engage lower edge portions of opposed pages of an open book supported by said stand.
Claim 9
Dependent Claim 29 words
The book stand of claim 12, wherein said means for securing includes an elastic band extending about said base panel and said support panel with the book disposed therebetween.
