ABSTRACT:
An interlocking release mechanism uses a toothed pinion engaging a toothed rack or gear. The teeth of the pinion are removed in certain areas so as a lock arm, when moved axially from in alignment with a tooth segment to where the tooth has been removed, permits the pinion to be rotated by the rack. The rack and the lock arm must be operated in the correct sequence or the lock arm will be jammed. With the correct sequence of lock arm motion and pinion rotation by the rack or gear, the rack or gear may be moved to achieve the desired release action of the subject invention.
