<p>A book holder assembly (10) is described including a vertical lower tube (22) mounted to a counterweighted base (12) also usable as a book storage space, or alternatively the lower tube (22) is provided with a clamp (136) enabling clamping to a desk top. An upper tube (44) is telescoped to the lower tube (22) to allow a height adjustment, and angled arm portion (58) of the upper tube (44) connected to a planar book shelf (84) by a swivel joint connection (86) which allows swinging rotation of the book shelf (84) as the upper tube (44) is swung in the lower tube (22) to maintain perpendicularity to the line of sight of the reader. Complete 360° tilt pivoting of the book shelf (84) is also allowed by the swivel joint connection (86). A book held on the book shelf (84) by straps (92) and spring finger page holders (102) may be set in position by various rotational movements of the upper tube arm (44) and swivel joint connection (86).</p> |
