Abstract
A range of motion limiting device for limiting the range of motion of a rotating input assembly on a trunk extension/flexion test, rehabilitation and exercise machine. The device has a cam lock and a cam lock housing, each of which is one integral piece. The cam lock has a cylindrical cam base, a cam extending from the cam base, an L-shaped tongue and a bracket. A shock absorber is mounted in the bracket. The cam lock housing has a locking knob thread for a locking knob, an L-shaped groove into which the L-shaped tongue of the cam lock fits when the device is assembled, an elongated hole for receiving the cam and cam base of the cam lock, and a ring clamp groove which nests around a semi-circular ring which is mounted on the machine. The device is assembled by inserting the cam and cam base into the elongated hole of the cam lock housing and rotating the cam lock relative to the cam lock housing to a final assembled position. The device is then slid onto one end of the semi-circular ring and secured on the ring by turning in the locking knob. When an input assembly of the machine hits the shock absorber, the cam rotates against an inside diameter of the semi-circular ring firmly se…
