Abstract
Abstract A plate-like support member of rectangular configuration has a surface, a first pair of parallel edges and a second pair of parallel edges perpendicular to and shorter than the first pair of edges bounding the surface. A mounting device is swivelly affixed to the support member at an upper of the first pair of edges and swivelly affixed to the headboard of a bed for adjustably selectively positioning the support member relative to the headboard. A ledge extends from the surface of the support member along a lower of the first pair of edges and has a first ledge surface parallel to and spaced from the surface of the support member and a second ledge surface perpendicular to the surface of the support member and extending from the surface to the first ledge surface for supporting a book resting on the support member in open position. Cover clamps are mounted on the support member at the second pair of edges thereof for releasably retaining the covers of the book in abutment with the surface of the support member.

A book holding device for a bed having a headboard, said book holding device comprising a substantially plate-like support member of substantially rectangular configuration having a surface, a first pair of substantially parallel edges and a second pair of substantially parallel edges substantially perpendicular to and shorter than the first pair of edges bounding the surface; mounting means swivelly affixed to the support member at an upper of the first pair of edges and swivelly affixed to the headboard of a bed for adjustably selectively positioning said support member relative to the headboard; ledge means extending from the surface of the support member along a lower of the first pair of edges and having a first ledge surface substantially parallel to and spaced from the surface of the support member and a second ledge surface substantially perpendicular to the surface of the support member and extending from said surface to the first ledge surface for supporting a book resting on the support member in open position, said ledge having a substantially L-shaped channel formed therein and extending longitudinally thereof, said channel having a top slot opening in the second ledge surface, said top slot being parallel to the first ledge surface, and a side slot opening in the first ledge surface, said side slot being parallel to the second ledge surface; cover clamps mounted on the support member at the second pair of edges thereof for releasably retaining the covers of the book in abutment with the surface of said support member; and page clamp means including a plurality of independent page clamps of substantially L-shape movably mounted in the ledge means for movement in directions parallel to the first pair of edges in proximity with the surface of the support member, each of the page clamps having a first arm movably mounted in the part of the channel opening in the second ledge surface and extending substantially parallel to the surface of the support member from the second ledge surface and a second arm movably mounted in the part of the channel opening in the first ledge surface and extending substantially perpendicular to said surface from the first ledge surface for facilitating manual positioning of said page clamps.
Claim 2
Dependent Claim
369 words
A book holding device for a bed having a headboard, said book holding device comprising a substantially plate-like support member of substantially rectangular configuration having a surface, a first pair of substantially parallel edges and a second pair of substantially parallel edges substantially perpendicular to and shorter than the first pair of edges bounding the surface; mounting means swivelly affixed to the support member at an upper of the first pair of edges and swivelly affixed to the headboard of a bed for adjustably selectively positioning said support member relative to the headboard; ledge means extending from the surface of the support member along a lower of the first pair of edges and having a first ledge surface substantially parallel to and spaced from the surface of the support member and a second ledge surface substantially perpendicular to the surface of the support member and extending from said surface to the first ledge surface for supporting a book resting on the support member in open position, said ledge having a substantially L-shaped channel formed therein and extending longitudinally thereof, said channel having a top slot opening in the second ledge surface, said top slot being parallel to the first ledge surface, and a side slot opening in the first ledge surface, said side slot being parallel to the second ledge surface; cover clamps mounted on the support member at the second pair of edges thereof for releasably retaining the covers of the book in abutment with the surface of said support member; and page clamp means including a plurality of independent page clamps of substantially L-shape movably mounted in the ledge means for movement in directions parallel to the first pair of edges in proximity with the surface of the support member, each of the page clamps having a first arm movably mounted in the part of the channel opening in the second ledge surface and extending substantially parallel to the surface of the support member from the second ledge surface and a second arm movably mounted in the part of the channel opening in the first ledge surface and extending substantially perpendicular to said surface from the first ledge surface for facilitating manual positioning of said page clamps.
Claim 3
Dependent Claim
31 words
A book holding device as claimed in claim 1, further comprising a lamp mounted on the support member at the upper of the first pair of edges for illuminating the book.
