ABSTRACT:
A table surface (11) adjusts in set increments to a variety of vertical positions. The table surface (11) moves only in a vertical direction, as determined through use of a vertical guide (16) that traverses a vertical tract (15). A tooth (35) and pawl (40) assembly controls the vertical disposition of the assembly such that the table surface (11) is incrementally raised to different vertical positions of choice. Once the table surface (11) has been raised to its uppermost limit, the pawl (40) becomes locked in a non-tooth engaging position, thereby allowing the table surface (11) to be lowered to its lower most position. When so lowered, the pawl (40) is released from its non-engaging position, such that the pawl (40) again engages the teeth (35) to allow the table surface (11) to be incrementally raised as before.
