Abstract
An elevator interlocking mechanism interlocks the elevator cage door and each landing door, and includes a release mechanism for release of the interlocks when the elevator cage is at rest at a landing. The elevator cage interlock comprises an elevator door locking rod which in a locking position engages a lock pin to prevent the elevator cage door from being opened. Each landing interlock includes a corresponding landing door locking rod which in a locking position engages a locking pin, which prevents the landing door from being opened. The locking rods are jointly operated by a single operating device so that the operating device--at a proper landing position--displaces the elevator locking rod from its locking position, and in turn the locking rod displaces a landing door locking rod from its position using a cam.
