Abstract:
The invention relates to a device provided with a driving unit (1) which performs the shift and has a linear drive (8,12) provided with an electric motor (5), and a guide device (9,11). The driven member, formed to be linear, of the linear drive (12) and a member of the guide device (9) are fastened on one hand to the door (3), and the driving member of the linear drive (5,7,8) and the other member of the guide device (11) are fastened on the other hand to a mounting (6) which is supported by way of a support arrangement (22, 23, 24, 25, 26) connected to the wall(4). Said support arrangement converts a movement of the mounting substantially perpendicular to the wall into a swinging movement. A locking unit driven by an electric motor is also provided which locks and unlocks the sliding door by performing a movement perpendicular to the wall when it is positioned to close the opening. Control means which has position switches controls the driving and locking unit.
Abstract:
A device for suspending and moving a door leaf perpendicular and parallel to a wall. The device comprising a first set of rails extending in a direction perpendicular to the wall, a second set of rails extending in a direction parallel to the wall and an elongated member which extends both parallel to and perpendicular to the wall. The door leaf is slidably mounted on the first set of rails and the first set of rails is slidably mounted on the second set of rails. The door leaf includes a motor which operatively engages the elongated member to move the door leaf perpendicular to the wall and parallel to the wall to open and close an opening in the wall.
Abstract:
A device for engaging and disengaging the driving mechanism of an automatic slide gate. The device uses a series of two levers to develop a substantial mechanical advantage in the operation of a dog clutch. An actuating lever is positioned so that it may be operated by the user's foot, eliminating the need for any auxilliary levers or tools.
Abstract:
A power door operator for mounting overhead of a door opening in a mass transit vehicle for moving a door panel over and away from the door opening, including a base plate incorporating a rotary helical drive internal of a door hanger. The door panel is locked in a closed position by primary and secondary means preventing drive rotation and panel movement.
Abstract:
A drive unit provided with an end position recognition device includes a radially projecting cam (27) connected to a driveshaft (20) of the drive unit, for reducing the stroke travel of the unit. The radially projecting cam engages, from tooth to tooth, into the inner toothing of a ratchet wheel (110), rotatable about an axis of rotation (111) that is offset and parallel to an axis of the driveshaft (20). The end position recognition device can be retrofitted and is preferably capable of operating even in the case of emergency manual actuation. The cam (27) has a sufficient axial stroke lift such that, in the case of emergency manual actuation, it nonetheless meshes with the ratchet wheel (110) even when the driveshaft (20) is displaced axially.
Abstract:
A manually releasable coupling device for connecting an elongate operator chain (2) with a frame or main frame member of a window comprises a first coupling member (3) for connection with a free end of the operator chain (2) and a second coupling member (6-10) designed for mounting in or on the frame or main frame member. The first coupling member is a flat disc-shaped element (3) with a substantially keyhole-shaped recess 85), while the second coupling member comprises a shaft section (6) for mounting in a bore in the frame member or the main frame member in connection with a turning handle (7). The shaft section (6) has a local constriction (8) for releasable engagement with the keyhole-shaped recess (5) in the disc-shaped element (3). In order to allow manual closing of the window under surmounting of sealing pressure, the shaft section may be eccentric relative to the rotational axis of the turning handle.
Abstract:
A side mount garage door operator capable of being positioned on either the ceiling or end wall of a garage at either side of the garage door on a frame unit, the operator providing a clutch for disengaging the drive motor from the garage door in the absence of electric power and having a manual graspable handle operated by a solenoid when power is present and operable manually in the absence of power. Novel limit means having limits which is on the end of an axially movable bar which is moved by a follower riding in a spiral groove in the base of a disk such as a gear connected to the drive shaft.
Abstract:
Control systems including control circuitry and optional communications systems for operating a sliding 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. Control circuitry is preferably provided in the body and the door of the vehicle for supervising and carrying out the foregoing functions in an orderly manner in response to requests generated locally at the door or remotely by the driver from the console of the vehicle. A second, simpler, control system provides electrically-actuated mechanisms for unlatching the door and operating the door lock without the use of either a wireless communication system or a retractable electrical cable interconnecting the sliding door to the vehicle body.
Abstract:
A power drive for a sliding door includes a slider for guided sliding movement along a fixed path between first and second end limits of movement. The slider operably engages with a sliding door to impart motion from the slider to the sliding door when traveling in a first direction. A reversible power drive is provided for driving the slider along the fixed path between the first and second end limits of movement in first and second directions of travel. A latch release, coupling the slider to the sliding door, initially releases a latch mechanism and, after release of the latch mechanism, transfers motion from the slider to the sliding door when traveling in the second direction.
Abstract:
A security enclosure includes an access gate comprising at least one rigid barrier which can be retracted or advanced by remotely-actuated power means for opening and closing the gate. A support and drive structure which supports the driven end of the barrier includes upper drive means which provide positive drive connections to an upper surface of the barrier through downward pressure on at least two laterally-separated points and corresponding lower drive means which provide positive drive connections to a lower surface of the barrier and support the barrier on at least two laterally-separated points, with the upper and lower drive means being driven by a common power source and connecting drive means to open and close the gate. Remote switching means are provided to operate the drive means and latch means to open and close the gate. The upper and lower drive means can be rollers driven by belt drives. The barrier and/or fence can include framework structures of tubular stock, the tubes being interconnected to permit the insertion of reinforcing cables.
