A pneumatic table that adjusts to various positions. Pneumatic cylinders controlled by a pneumatic system raise and lower the tabletop to a desired position. Brakes are used to lock the tabletop once it is in its desired position. The tabletop tilts forward and backward to vary the operating position of a piece of machinery located on the tabletop. A self-adjusting foot treadle adjusts when the tabletop height is changed such that the linkage between the treadle and the tabletop is maintained. The treadle also adjusts to various positions for the comfort of the operator.

A pneumatically adjustable table for presenting a work surface and allowing a worker to vary the height of the work surface relative to the worker by using a compressed air supply, comprising: a generally planar tabletop defining a plane having an orientation with respect to horizontal and having a work surface, a bottom surface, a front edge, a back edge, a left edge and a right edge; a generally vertical support member disposed for movement in a generally vertical direction, up and down; a pneumatic drive mechanism for moving said support member at least in an upwardly direction; conduit means for supplying compressed air from the air supply to said pneumatic drive mechanism; control means for controlling the supply of air from the air supply to said conduit means for selectively causing the pneumatic drive mechanism to move to support member; and means for attaching said support member to said tabletop said tabletop moveable between at least raised and lowered positions by said support member in response to said control means, said plane defined by said tabletop substantially maintaining said orientation with respect to horizontal in said raised and lowered positions; said table further comprising an adjustable foot treadle system for use in manipulating an apparatus located on said tabletop that adjusts to changes in said tabletop height, said adjustable foot treadle system comprising: a foot treadle; a first rod having first and second ends and a length; a second rod having first and second ends and a length, disposed parallel to said first rod, said first rod attached to said foot treadle at said first end, said second end of said first rod extending upwardly toward said tabletop, said length of said first rod insufficient for said second end of said first rod to each said tabletop and said first end of said second rod extending downwardly, parallel to said first rod, toward said foot treadle, said second end of said second rod extending upwardly, beyond said second end of said first rod, and connected to the apparatus located on said tabletop; and an adjustable linkage means attached to said first rod and slidably disposed to said second rod for allowing the second rod to slidably adjust without changing position of said foot treadle and for locking said first and second rods in place.
