Abstract:
The invention relates to a furniture drive for driving a movable piece of furniture, comprising an electric motor, an actuator that can be moved back and forth between two end positions to apply a force on the piece of furniture to be driven, and a gearbox connected between the electric motor and actuator, wherein the gearbox has at least one gear stage configured as an eccentric gearbox and comprising two gear wheels that mesh with each other, wherein one of the two gear wheels is firmly connected or coupled to the actuator and the other gear wheel is coupled to the electric motor such that the eccentric gearbox has two limit positions, which correspond to the end positions of the actuator, and upon a rotation of the gear wheels, starting from the limit positions, the gear ratio decreases over a deformed rotational angle range.
Abstract:
A drive for a movable furniture part includes a motor to power the movable furniture part and a control or regulation unit to control or regulate the motor. The control or regulation unit is designed such that it has a threshold value which, if surpassed, causes the actuation of the movable furniture part by the motor. A measurement device is provided to capture the position of the movable furniture part, and the control or regulation unit is designed in such a way that the threshold value varies for at least two different positions of the movable furniture part.
Abstract:
A device for controlling the movement of a both motorically and manually movable vehicle part comprises a drive unit controllable in its rotational speed for motorically moving the vehicle part, a coupling device for coupling the drive unit with the vehicle part and a control unit which controls the drive unit and the coupling device such that during manually moving the vehicle part the coupling device couples the drive unit with the vehicle part if the vehicle part has reached a pre-defined position. For this, the control unit (3) controls the rotational speed of the drive unit (2) in dependence on the moving speed of the vehicle part (10). In this way a device and a method are provided which in an easy and low-wear manner allow for a control of the movement of a both motorically and manually movable vehicle part.
Abstract:
Under a method to control a sliding speed in accordance with this invention, the motor is initially accelerated for a predetermined reference speed, and then during the initial acceleration period, if a rotational speed of the wire drum is of and above a given value, a difference between a rotational speed of the wire drum and a rotational speed of the motor is of and above a given value, and a rate of acceleration of the wire drum is of and above a given value, the rotational speed of the motor is reduced temporarily judging the slide door is in a state of abnormal acceleration, and then the motor is accelerated again at a lower rate than the initial acceleration toward the reference speed.
Abstract:
A refrigerator and/or freezer with an appliance carcass, can be closed by at least one door, and a powered door operating device for automatically operating the door. The door operating device has drives both automatically opening and closing the door.
Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
Abstract:
A powered opening and closing system includes a door supported on a vehicle body, a motor, a drive mechanism for moving the door in opening and closing directions by virtue of power of the motor, an operation detecting sensor for detecting a handle operation when-the door is operated to open or close, and a control circuit for prohibiting the operation of the drive mechanism when a predetermined operation prohibiting condition is detected. The drive mechanism brakes the movement of the door by putting the clutch in an engaged state while the motor is kept stopped. While the predetermined operation prohibiting condition is detected, the control circuit controls the clutch to be engaged while keeping the motor stopped when an opening of the door is detected, and controls the clutch to be disengaged when an operation of the handle is detected by the operation detection sensor.
Abstract:
A door operating apparatus includes a motor bracket that covers a driving shaft of a driving motor; an output shaft that is disposed from the motor bracket toward the supporting bracket so as to be orthogonal to an extending direction of the driving shaft; a first rotational element that is linked with the driving shaft, and disposed on the output shaft; a second rotational element that is linked with a door operating mechanism, and disposed between the first rotational element and the supporting bracket on the output shaft; and a clutch unit including a clutch driving section that supports a rotation of the output shaft. When the first rotational element and the second rotational element are engaged by driving of the clutch driving section, the door operating mechanism is actuated by the driving force.
Abstract:
An anti-pinch system of a vehicle closure includes a detection system for detecting pinching and a clutch to disconnect the vehicle closure from a closure driving mechanism following detection of pinching by the detection system. The closure drive mechanism can be disengaged to prevent an increase in pinching during the time required to reverse the movement of the closure driving mechanism.
Abstract:
A drive arrangement for the motorized movement of a functional element in a motor vehicle. An electric drive motor moves the functional element in two directions via a first drive train and a second drive train. The drive force is transmitted simultaneously via the two drive trains in at least one of the two directions of movement of the functional element. One of the two drive trains comprises cable-operated speed transforming transmission with a drive cable which is used to transmit drive force while the other of the two drive trains is a cableless drive train. A differential with two outputs can optionally be connected downstream from the drive motor with the drive trains then extending from the outputs of the differential.
