Patent

CA 2234181

A locking mechanism for chairs such as gliding and rocking chairs comprises a toothed rack for connection to the chair seat with the rack oriented generally in the direction of movement of the chair seat relative to the base and the teeth extending along the rack and facing towards a pin that is carried in the base. The rear end of the rack is pivoted to the chair seat and the front end of the rack is connected to a pivoting linkage arrangement operated by a lever at the side of the chair seat. Operation of the lever is effective to swing the toothed rack from a retracted position to a lowered position wherein the locking pin is engaged by a registering tooth in the rack. The attitude of the chair in the locked position will depend upon the position of the locking interengagement between the pin and the toothed rack.
