Abstract:
An automatic door opener (10) for opening or closing a door (28) includes a motor (14) driving a drive shaft (50) and an opener arm (18) connected to the door (28) and being responsive to rotation of the drive shaft (50) for moving the door (28) to an open or closed position. A clutch (46) operable to disengage the drive shaft (50) from the opener arm (18) is provided in the event of the door (28) engaging an obstacle, electric power being unavailable, or the door being fully open or fully closed. The door opener (10) may also include a brake (48) for selectively preventing movement of the door (28). Various embodiments of the invention are provided, including an electromagnet (80) and an electromagnetic brake (114).
Abstract:
A clutch comprises an input pinion and an output pinion associated with a rotatable locking member that has a surface inclined with respect to an axis of rotation of the locking member. The surface cooperates with an engagement member, and the locking member is movable between a first position and a second position. In the first position, the surface forms a recess to receive the engagement member, and in the second position, the surface forms a projection to force the engagement member into abutment with the input pinion to establish a driveable connection between the input pinion and the output pinion.
Abstract:
A drive arrangement is provided for motorized pivotal movement of a vehicle door. The drive has a self-locking motor unit, a gear connected downstream of the motor unit for producing linear drive movement, and a clutch connected therebetween. The clutch can be moved into an engaged state in which the motor unit for nominal operation is engaged to the vehicle door. When the motor unit is turned off, manual movement of the vehicle door is blocked. The clutch can be moved into a released state in which the motor unit is separated from the vehicle door in terms of drive engineering. The clutch can be moved into the intermediate engaged state with reduced transmission moment and force so that the vehicle door is kept in its current position at any time by self-locking of the motor unit, but can be moved by manual actuation with a minimum actuation force.

A power drive assembly for a rear lift gate assembly of a vehicle includes a screw drive having a screw member and a clutch supported by the screw member.
Abstract:
The invention relates to an electromagnetic friction clutch for arrangement within a drive train connecting a drive motor and a vehicle door. The vehicle door is reliably held in any intermediate position when a clutch is disconnected. To preserve the ability to carry out a manual emergency actuation of the vehicle door, a compression spring is provided acting upon an armature disk of the clutch in the axial direction in such a way that, with the clutch in the disconnected state, the armature disk is pressed against the frictional lining of a rotor part with a force which is sufficient to ensure that the vehicle door remains reliably in position. During a subsequent manual actuation of the vehicle door, the frictional connection between armature disk and frictional lining can be overcome.

Abstract:
A driving device for driving an open/close member that is designed to open and close an open portion of a body includes a driving source generating a driving force, a force transmission mechanism disposed between the driving source and the open/close member and serving for transmitting the driving force thereto, and a load regulator for interrupting the driving force transmission when an excessive force is applied to the force transmission mechanism from the open/close member.
Abstract:
An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.
Abstract:
The present invention relates to a door operating system for controlling the movement of a door, more particularly to “no touch” door openers for public washrooms and households. The system has a motor with a gear chain where the high gear is generally semicircularly shaped engaged with a swinging arm coupled with the door through the roller and a pilot plate. The unit is activated upon receipt of the signal from overhead passive infrared or hand proximity detecting sensors and has a controlling system to provide for opening and closing the door, as well as retraction of the arm in the event of door encountering an obstacle or in an overload condition of the motor. The arm and a gear are linked pivotally with each other and with the unit housing. They are coupled through a spring suspension system and have a clutch mechanism preventing overloading. The only external moving part is the arm, which is, along with geared sector, protected by a flexible member providing security to prevent accidental jamming of objects by it. The unit may be battery operated with a low voltage and low power AC/DC switching wall adapter. In autonomous operation it can provide up to 700 opening cycles without external power.
