ABSTRACT:
A table includes a tabletop and adjustable legs. Each table leg includes an inner tube attached to the tabletop, and an outer tube slidable on the inner tube. The inner tube includes a lengthwise keyway and a snap locking device in the bottom end of the tube. The locking device includes a sleeve, a compression spring within the sleeve, and a dowel pin urged by the spring through radial opening. The outer tube includes holes spaced therealong and a bushing mounted in the top end, the bushing including a key for engagement with the keyway of the inner tube. Length adjustment of the tubular table height adjuster is made by depressing the dowel pin and sliding the outer tube along the inner tube until the dowel pin snaps into a desired one of the holes in the outer tube.
