Abstract
A locking mechanism for a mobile storage system comprises a reciprocable lock bar selectively engageable with a rack fastened to a system track. The lock bar is moved into and out of engagement with the rack by a push-pull cable actuated by a conventional key and lock device. The lock bar is urged into engagement with the rack by a spring. Each rack tooth is formed with a vertical and a sloping surface, and the lock bar has cooperating surfaces. When the mobile storage unit is moved in one direction the lock bar ratchets over the teeth sloping surfaces against the spring bias, but movement is prevented in the opposite direction because the spring urges the lock bar vertical surface into cooperating engagement with a rack tooth vertical surface.
