The locking assembly includes an arm that engages the flag. The flag then prevents the arm from reaching its maximum tilt and keeps it in the substantially vertical position. This causes the hook in the locking assembly to remain in the lowered position. The hook in this position allows the cable to freely travel when the elevator doors are attempted to be open. If the elevator is in a locking zone, then there is no flag present and as the door is attempted to be open, a weighted member attached to the bottom of the cable will begin to rise. However, because no flag is present to hold the arm back and subsequently, keep the hook lowered, an elongated spring biases the hook upwards until it engages a locking pin mounted to the weighted member. This prevent the cable from traveling freely throughout the shaft, thereby keeping the elevator doors locked. | 12-17-2015 |
