An I-shaped page retainer is pivotally mounted on the rack and includes laterally extending upper and lower fingers for holding opposing pages of the book open for reading. The page retainer includes telescoping segments such that the distance between the fingers can be adjusted to accommodate different size books. A book light optionally can be attached to the book rack for lighting the pages.
Description




BACKGROUND OF THE INVENTION




Book stands for holding books are well known. Typically, prior art book stands include a base, an arm extending upwardly from the base, and a rack for holding the book. The rack on prior art book stands normally includes fingers for holding the pages open.




Such conventional book stands usually rest upon the floor, and thus are relatively large, and heavy so as to provide stability. Also, these conventional book stands are complex in construction, and thus expensive to manufacture and sell.




Accordingly, the primary objective of the present invention is the provision of an improved book stand for holding open the pages of a book for reading.




Another objective of the present invention is the provision of a book stand which is lightweight, yet stable.




Another objective of the present invention is the provision of a book stand which holds the pages of the book open without interference.




A further objective of the present invention is the provision of a book stand which allows quick and easy turning of the pages.




Another objective of the present invention is the provision of a book stand having a base upon which a person sits to stabilize the stand.




A further objective of the present invention is the provision of a book stand which is portable.




Still another objective of the present invention is the provision of a book stand which is economical to manufacture and durable in use.




These and other objectives of the invention will become apparent from the following description of the invention.




SUMMARY OF THE INVENTION




The book stand of the present invention is lightweight and portable. The stand includes a base which is adapted to be sat upon by a person in a chair so as to stabilize the base. First and second arms extend upwardly from the base and are telescopically joined to provide height adjustment. A book rack is attached to the second arm and includes a shelf for holding a book. The rack is pivotally mounted for rotation about a horizontal axis, such that the angle of the book can be adjusted. The first arm is pivotally connected to the base for movement about a horizontal axis such that the spacing between the book rack and the reader can be adjusted. The rack includes an I-shaped page retainer, including a central beam extending along the inner spine of the book and laterally extending fingers to hold opposing pages of the book open for reading. The page retainer is pivotally attached to the rack for movement between a first position engaging the open book pages, and a second position disengaged from the pages so that the pages can be turned. The central beam of the page retainer includes telescoping segments such that the distance between the upper and lower fingers can be adjusted, thereby accommodating different sized books. A light may be mounted on the rack to illuminate the book pages.

DETAILED DESCRIPTION OF THE INVENTION




The book stand of the present invention is generally designated in the drawings by the reference numeral


10


. The stand


10


includes a base


12


, a first arm


14


pivotally connected to the base


12


, a second arm


16


telescopically extending from the first arm


14


, and a book rack


18


supported on the second arm


16


.




More particularly, the first arm


14


is L-shaped, with the lower end being connected to the base


12


by a pivot connector


20


such that the arm


14


is pivotal about a horizontal axis. The pivot connector as shown in the drawings includes a fixed member


22


secured on the base


12


by a shaft


23


and an adjustment member


24


which supports the first arm


14


. The adjustment member


24


is spring mounted to the fixed member


22


and includes a pair of pins


26


which can be selectively received in the holes


28


in member


22


so that the angular position of the first arm


14


can be selectively fixed. Thus, member


24


can be pulled away from member


22


and then rotated until the arm


14


is in a desired position. The member


24


is then released so as to spring back toward member


22


with the pins


26


in the selected holes


28


. It is understood that any conventional pivot joint can be utilized for the connection between the first arm


14


and the base


12


, without departing from the scope of the present invention.




The upper end of the first arm


14


is hollow and telescopically receives the lower end of the L-shaped second arm


16


, as best seen in

FIGS. 2 and 3

. A spring loaded pin


30


extends through the first arm


14


and through one of a plurality of holes


41


in the second arm


16


. The pin


30


can be retracted so the second arm


16


can be slideably moved upwardly or downwardly within the first arm


14


, thereby adjusting the height of the book rack


18


.




The second arm


16


includes a rack support or yoke


34


extending to opposite sides of the rack


18


and pivotally secured thereto by wing nuts


36


, or any other convenient pivotal attachment mechanism. Thus, the rack


18


is pivotally supported by the yoke


34


such that the angle of the rack is adjustable.




The book rack


18


includes a shelf


38


to support a book


40


. A page retainer


42


is pivotally connected to the shelf


38


. The precise structure of the pivot connection between the shelf


38


and the page retainer


42


is not shown, but it is understood that such pivot connection may be a hinge, a spring, a rubber connector, a slip fit, or any other pivotal attachment allowing the page retainer


42


to move between a first position engaging the pages of the book


40


, as shown in solid lines in

FIG. 4

, to a second position disengaged from the book pages, as shown in broken lines in FIG.


4


. In the second position, the book pages can be easily turned, and the page retainer


42


then moved back to the first position to hold the pages open.




Preferably, the page retainer


42


is I-shaped, and includes a central beam


44


and laterally extending upper and lower fingers


46


,


48


. The upper and lower fingers


46


,


48


extend across the upper and lower margins of the book pages, with the text residing between the fingers


46


,


48


. Thus, the fingers do not obstruct any text, and the reader may highlight or underline desired text. The central beam


44


includes telescoping segments


50


,


52


, such that the distance between the upper and lower fingers


46


,


48


can be adjusted. The segments


50


,


52


may be constructed similar to the arms


14


,


16


, with a spring loaded pin extending through one of a plurality of holes in the upper segment


52


. Alternatively, the segments


50


,


52


may be frictionally assembled for slidable movement relative to one another. A battery powered light


54


may be mounted on the rack


18


so as to illuminate the pages of the book


40


.




In use, a reader positions the base


12


of the book stand


10


beneath his or her leg or buttocks while seated. The first arm


14


is pivoted such that the rack


18


is at a desired distance from the reader's eyes. The height of the rack


18


is adjusted by telescoping the second arm


16


relative to the first arm


14


, via the retainer pin


30


. The angle of the rack


14


and book


40


are adjusted by loosening and tightening the wing nuts


36


. The page retainer


42


is moved to the second position, so that the book can be positioned on the shelf


38


and opened to the desired pages. Page retainer


42


is then pivoted into engagement with the book pages so as to hold the book open. Thus, the reader's arms are free from holding the book. To turn the book pages, the page retainer is quickly and easily pivoted from the first page retaining position to the second position so that the pages are free to be turned.




The book stand


10


is lightweight and portable so that it can be used indoors or outdoors, or in a motor vehicle, such as a car, truck or bus.




The preferred embodiment of the present invention has been set forth in the drawings and specification, and although specific terms are employed, these are used in a generic or descriptive sense only and are not used for purposes of limitation.
