An elevator system including an elevator car having an electromechanical door restraint mechanism which prevents the forceable opening of an elevator car door by passengers when the elevator car stops outside a predetermined zone adjacent to a floor level, at least to an extent which would enable passenger exit from the car.

Elevator system

A hydraulic elevator system which utilizes a single hydraulic jack having a cylinder fixed below an elevator car, and a plunger. The elevator car is supported on the end of the plunger. The hydraulic jack extends upwardly and into the elevator car, reducing the space required below the car by the amount of the penetration of the hydraulic jack. The hydraulic jack is disposed adjacent to the front portion of the hatchway, enabling it to occupy an enclosed, concealed space in the elevator car, between its entranceway and its operational controls.

An elevator system including an elevator car an enclosure on top of the elevator car, a passenger opening in the elevator car, a door operable between open and closed positions relative to the passenger opening, a door operator for the door a car top inspection station, and a traveling cable. Controls for the door operator are mounted within the enclosure, and controls for the car top inspection station are mounted on a side of the enclosure. The traveling cable is connected to the enclosure. Open wiring in the enclosure interconnects the electrical components of the door operator, the car top inspection station, and the conductors of the traveling cable.

Elevator system having common enclosure for open wiring between door

An elevator system including an elevator car, a passenger opening in the elevator car, a door operable between open and closed positions relative to the passenger opening, and a door operator for the door. The door operator includes a drive motor, a drive for imparting linear motion to the door, speed control and limit switches, associated door control, and various accessory equipment, such as emergency lighting control, alarm bell, and control for object sensing door re-opening devices, all mounted within a common enclosure on the top of the elevator car, which permits open wiring between the electrical components. The common enclosure also functions as the hanger roller track and up thrust roller guide.
