Abstract:
1. An infinitely variable means for adjusting an angle of a movable foot within a fixed base by translating rotational axial movement into vertical axial movement which comprises: (a) at least a partially threaded rod inside said fixed base, said rod penetrating through said base and having a knob disposed at said penetrating end; (b) a follower for axial movement on said rod at said threaded end (c) at least one follower extension on said follower; and (d) an inclined surface for impingement with said at least one follower extension, and wherein (e) said movable foot has at least one laterally extending projection on each side of said movable foot for insertion into a mating groove in said fixed base, thereby defining a vertical axis within a defined range of travel.
