ABSTRACT:
An adjustable, manually operated, table support system which allows the user to achieve various heights and angles of an attached surface ,while remaining seated where the surface load to the floor is distributed on four independent continuous posts. Each post is telescoping having a friction locking device attached to each. The locking devices are paired off and linked together on a actuation lever on each by a common connecting pin. This pin is in turn connected by a connecting rod to a rocker lifter situated above the two locks. Rockers of each leg unit are linked by a common actuating lever so that when force is applied to the lever both rockers rotate, lifting both connecting pins, and thus all four locks are actuated at the same time. A surface connecting system is incorporated whereby an attached surface will be allowed to rotate and slide on the telescoping posts to provide for changes of surface tilt angles.
