ABSTRACT:
A table for use in administering chiropractic adjustments including at least one column mounting a body support and vertically movable relative to a base. Detent means bear against the column. A first air cylinder serves to elevate the column. A second air cylinder imposes a force against the detent means to provide a braking effect to hold the column at the upper limit of travel when the column is raised with a patient lying in part on the body support. When air pressure is shut off to both cylinders, the first cylinder retracts and air pressure is trapped in the second cylinder. The force imposed by the air pressure in the second cylinder to maintain the braking effect is substantially equal to the force required to lift the weight of the patient carried on the body support. The braking effect is overcome when a chiropractic thrust is applied to the body of a patient.
