Abstract
Abstract A combined page holder and book support is disclosed herein having a shaped base formed with a pair of cut-outs along a selected end of the base and an elongated slot along the central longitudinal axis opening at the other end of the base. A pair of tab members are pivotally carried on the selected end of the base and rotate in and out of the respective cut-outs. A U-shaped support member is pivotally carried at the sides of the base and constitute a back for supporting an open book while the tab members constitute a pair separator. A brace is pivotally carried on the base and rotates into and out of the elongated slot. The brace detachably engages with the U-shaped member so as to support in an angular relationship to the base.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A book support and holder for supporting a book in its open condition to separate or divide the pages comprising the combination of: a base having a predetermined configuration; a U-shaped member having a cavity corresponding in shape to said base predetermined configuration and being pivotally carried adjacent a selected end of said base so as to rotate between a first position substantially angularly disposed with respect to said base and a second position substantially flat and coplanar with respect to said base; a brace pivotally carried on said base for releasably engaging with said U-shaped member in said first position; a pair of tab members pivotally carried along said selected base end and said base provided with a pair of cavities for receiving said tab members when said U-shaped member is in said second position; and said tab members and said U-shaped member cooperating to support and hold the book and papers open when said U-shaped member is in said first position.
Claim 2
Dependent Claim
163 words
A book support and holder for supporting a book in its open condition to separate or divide the pages comprising the combination of: a base having a predetermined configuration; a U-shaped member having a cavity corresponding in shape to said base predetermined configuration and being pivotally carried adjacent a selected end of said base so as to rotate between a first position substantially angularly disposed with respect to said base and a second position substantially flat and coplanar with respect to said base; a brace pivotally carried on said base for releasably engaging with said U-shaped member in said first position; a pair of tab members pivotally carried along said selected base end and said base provided with a pair of cavities for receiving said tab members when said U-shaped member is in said second position; and said tab members and said U-shaped member cooperating to support and hold the book and papers open when said U-shaped member is in said first position.
Claim 3
Dependent Claim
50 words
The invention as defined in claim 1 wherein said brace is an elongated member having one pivoted on said base at its end opposite to said selected end and said base includes a slot having a shape to receive said brace when said U-shaped member is in said second position.
Claim 4
Dependent Claim
31 words
The invention as defined in claim 2 including stop means cooperating between said base and said U-shaped member for resting said base within said U-shaped member cavity in said second position.
Claim 5
Dependent Claim
55 words
The invention as defined in claim 3 wherein said stop means includes a transverse slot provided in said base extending across said base and a rod carried on said U-shaped member across said U-shaped member cavity and said rod cooperating with said slot to arrest movement of said U-shaped member with respect to said base.
Claim 6
Dependent Claim
37 words
The invention as defined in claim 4 wherein said pivotal tab members include dowel pins for pivot connection with said base and said dowel pins are formed with a spiral groove and provide a yieldably frictional fit.
Claim 7
Dependent Claim
41 words
The invention as defined in claim 5 wherein said U-shaped member includes a pair of feet and said brace includes a foot so as to provide a triangular support for said base when said U-shaped member is in said first position.
Claim 8
Dependent Claim
25 words
The invention as defined in claim 6 wherein said brace includes a notch provided in its free end for detachably engaging with said U-shaped member.
Claim 9
Dependent Claim
49 words
The invention as defined in claim 7 wherein said U-shaped member is in the form of an arch with legs on each side terminating in said pair of feet and pivot connections for rotatably securing said legs to said base at a distance away from said selected base end.
Claim 10
Dependent Claim
51 words
The invention as defined in claim 8 wherein said second position constitutes a flat condition having a substantially constant thickness for the book support and holder such as for storage and said first position constitutes an in-use condition with said base resting on said pair of feet and said brace foot.
