Abstract:
An elevator door mover device (40) includes a threaded ferromagnetic shaft (42). Magnetic movers (48) associated with doors (26) generate magnetic fields that cause the doors to move responsive to rotation of the shaft (42). In one example, a controller (46) controls a speed of a motor (44) that drives the shaft (42). The controller (46) in some examples also selectively controls the strength of the magnetic fields of the movers, which provides more customizable door performance.
Abstract:
The invention relates to a blocking device for a door provided with a door closer (3). A sliding arm (32) is coupled with the end thereof on the door leaf or on the door frame. The other end of the sliding arm is guided with a glider (33) inside a track (4) in a moveable manner, said track being arranged on the door frame or door leaf. The glider (33) interacts with a stop (61) which is arranged in the track (4) and which is pushed in the movement area of the glider (33) by the action of a spring element (6). The stop (61) interacts with an electrically switchable control element (8). According to the invention, the control element (8) comprises a piezo-electric element, a magnetostrictive element, a thermostrictive element, a shape-memory element or a comparable actuator. In order to prevent deviation, the spring element (6) is alternatively supported in or released from a support point by a blocking element (7) which is preferably guided in an axial direction in the track, whereby the blocking element (7) interacts with the control element (8). The movement of the blocking element (7) is blocked in a first position of the control element (8) and, as a result, the spring element (6) is blocked. As a consequence, the glider (33) which is guided in the track (4) can not deflect the stop (61), and the door leaf remains blocked. The movement of the blocking element (7) is permitted in a second position of the control element (8). The action of a recoil spring (9) causes the blocking element (7) to move out of the blocking position thereof and to release the spring element (6). The glider (33) can thus deflect the stop (61) against the force of the spring element (6) and the door leaf closes.
Abstract:
A power door operator for transit vehicles utilizing a rodless pneumatic cylinder (10) to open and close doors (2, 3) in the sidewall of a vehicle. Door movement having a controlled door edge force is achieved through coupling an external piston (11) of the cylinder and vehicle doors through belt (16). Magnetic coupling between internal and external pistons of the cylinder provide force having breakaway value applied to the operated door. A novel lock (30, 31, 32, 33) operated by admission of air to the cylinder (10) latches or unlatches the door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area (10a) in the cylinder. Piston force is modified for positions approaching either end of the cylinder using a sliding rod (40) contained by the piston (10a). Movement of the rod modifies available force.

Abstract:
A system and method for detecting damage to a door system by detecting the presence or absence of a magnetic source attached to the door system for stopping motion or reversing motion of the door to prevent any further damage to the door system. For example, a roll-up type door may be damaged by a vehicle and pulled from its vertical support guides; detecting this event causes stopping of any motion of the door, such as opening or closing the door.
