ABSTRACT:
A kinetic therapeutic table 10 having a frame 12, a planar patient support 14 mounted to the frame 12 for rotation about an elongate axis substantially aligned therewith and adjustable vertically at its foot 20 and head 18 ends. A patient support 14 drive motor 28 provides rotary drive to the patient support 14 through a worm gear 40 locked to a gear linkage, so that it may be stopped and held by the worm gear 40 in any angular position by switching power off to the motor 28. The worm gear 40 is manually disengageable from the remainder of the gear linkage to enable manual movement of the patient support 14 to a horizontal position. A locking pin 76 is automatically biased against a drive ring 22 and springs into a pin hole 78 therein when the horizontal position is reached. The patient support 14 is mounted at one end of its pivot axis to the frame 12 by a ball 19 and socket 21 connection. The other end is connected to the drive ring 22 which is rotatably mounted to the frame 12 by means of idler wheels 26 and is otherwise rotatably driven by the motor 28 through the gear linkage. A electronic control circuit controls application of power to the motor 28 for selectively adjustable periodic movement of the patient support 14.
