ABSTRACT:
The invention relates to a means for the compact stowing of a folded support, e.g. for books and the like, when not in use, and to the unfolding thereof, to provide a rigid support in any one of a number of possible positions, from the compact stowed position.
More particularly, the invention provides a four-way movement of a book support means from an initial compact stowed position wherein the support means and its associated mechanisms all lie essentially in a single plane, to a position wherein the support means can be adjusted four ways: (1) rotationally and (2) vertically about a given horizontal axis, (3) laterally with respect to a given vertical axis, and (4) rotationally with respect to that given vertical axis.
