Abstract: Control systems including control circuitry and optional communications systems for operating a slding power-operated member of an automotive vehicle. A powered sliding door in an automotive vehicle, such as a van, moves along a predetermined path of travel between a closed position and a fully open position relative to the body of the vehicle. Such a sliding door may be provided with one or more electrically-operated actuators for performing functions associated with the door, such as power opening and closing the door, power unlatching the door, power locking and unlocking the door, and power clamping, and unclamping the door in a soft or low-momentum manner. The invention is directed toward improved control systems and circuitry for operating such power-sliding door systems. One such control system employs a wireless communications link between the door and body, which is preferably implemented using radio frequency communication signals containing digitally encoded control signals.

Abstract: A power drive system for a sliding door, such as those employed on van type vehicles, enables a positive drive powered operation of the door by a control switch remote from the door and a programmed electronic control unit while accommodating manual operation of the door without mechanical interference or resistance from the drive or altering of the drive control program. A push/pull cable connected to the door is in positive meshed engagement at all times with a rotary drive gear whose rotative displacement from a rest position is continuously transmitted to the electronic control unit as a door position input signal. During powered operation of the door, the control unit is programmed to actuate or control a reversible drive motor or associated devices when the door is at selected positions along its path of movement.

Abstract: An automatic operating system for swinging doors which is controlled by the user by means of a miniature, hand-held radio transmitter having a single operating pushbutton.Depression of the pushbutton results, sequentially, in the retraction of the deadbolt, the retraction of the main latch, and the opening of the door. The door then remains open until the pushbutton is again depressed, whereupon the main latch is extended, the door is swung to its closed position, the deadbolt is extended into its associated recess in the doorjamb, and the air pressure in the automatic door operating system is bled to atmospheric level, resetting the system to its normal or quiescent state.

Abstract: In an automatic door operating system, there is employed a so-called fail-safe means which controls a door closing device. The door closing device functions to enforcedly shift the door from its half-latch position to its full-close latched position. The fail-safe means is so arranged as to deal with such a possible undesirable matter that due to, for example, a foreign thing accidentally caught between the door and the vehicle body, the door is forced to stop during its shifting from the half-latch position to the full-close latched position. Upon this door stopping, a control switch is turned in the other direction by an operator (viz., driver). With this, the door closing device is operated in a reversed manner for a time given by a timer, so that the door is moved back to a position near the half-latch position thereby to facilitate the removal of the foreign thing.

Abstract: A reversible-screw- (3) and-nut (14) actuating device is connected by a coupling (12, 13) to a sliding door, the screw (3) itself being connected to a motor. A carriage (11) which can move along the screw comprises a lock (16, 22, 28, 24) for locking this carriage automatically when the nut (14) reaches one end of its travel and for unlocking it automatically when the screw is moved in the opposite direction.The lock (16, 22, 28, 24) can move with respect to the nut and is stressed toward a locking position by a helical spring (29) working in the direction of its winding. A manual unlocking means comprises a plate (37) which can move about an axis (40) so as to align the locking finger (22) and its roller (28) with a slide channel (23) counter to the spring (29), this unlocking being possible even when the screw forces in the direction of closing for safety reasons, the unlocking then being validated only when the screw is released.Application to a door of a public transport vehicle.See FIG. 3.

The arrangement includes a latch and pull down mechanism for the rear closure of the vehicle to move the same between a partially open and a closed position and a control means including door jamb switches for energizing the pull down unit to raise the rear closure to its partially open position in response to opening movement of the door and to return the same to its fully closed position in response to closing of the door.

Abstract: An air cylinder operates a loose link cam fixed to a rod which pivots the hatch cover which is normally latched closed. As the cylinder is operated, the first portion of the movement unlatches the cover and the remainder of the movement swings the cover up to an over centre position whereupon it falls by gravity to the fully opened position without any further movement of the cylinder. The loose link cam permits the cover to move through approximately 180.degree. during the opening motion. when closing the cover, the same action takes place with the latch moving to the closed position by means of a spring and being displaced by the cover falling to the closed position by gravity once it has been moved by the loose link cam to the over centre position. The upper surface of the latch hook is curved so that the edge of the cover cross bar strikes the latch and displaces same as the cover closes and which is then returned to the latching position by the spring.

Abstract: The invention is directed to a penumatic or hydraulic drive for opening and closing of doors, in which the linear motion of a double-acting piston 5 driven by a pressure medium is converted into a rotary motion of a spindle 2 through a piston rod 6 and a helical gear box 3. Herein a blocking lever 10 supported in a stationary manner is provided, which in the closed position of the door engages under the action of a spring 18 at a part 11 connected with a piston 5, wherein said blocking lever secures the piston in its end position and is held in its open position counter to the force of an additional spring 15 by a power cylinder 14 acted upon by the pressure means.

Abstract: An integrated panel control in which both the release and pulldown mechanisms are controlled by a single operator activated switch.
