A door drive device for adjusting and/or locking a vehicle door relative to a vehicle body includes an adjustment member and a drive element operatively coupled to the adjustment member. A sensor is configured to measure movement of the vehicle door and/or a force acting onto the vehicle door and to output a sensor signal. A control device is configured to control operation of the door drive device and is programmed to detect an action onto the vehicle door indicative of a user command for moving the vehicle door based on the sensor signal, and conclude for an action onto the vehicle door indicative of a user command for moving the vehicle door by evaluating a characteristic value derived from the sensor signal based on a decision parameter, wherein the decision parameter is variable depending on a movement direction of the vehicle door.

A hinge device 1 comprises a dumper hinge 2 and a gravity hinge 3. The gravity hinge 3 comprises a rotational force imparting mechanism 70 for converting gravity of the door 6 to rotational force to a closing direction when the door 6 rotates to the closing direction. The dumper hinge 2 comprises a dumper mechanism 30 for reducing the rotational force to the closing direction of the door 6. The dumper mechanism 30 includes a linear dumper 31 disposed to the first hinge member 10 and a first cam member 32 and includes a second cam member 35 disposed to the second hinge member 20. The linear dumper 31 is positioned far from the shaft member 40 in an orthogonal direction to a shaft line of the shaft member 40 and is positioned along the shaft member 40. When the door 6 rotates, the linear dumper 31 is shortened.

A door system is provided. The door system includes: a corridor sized to allow humans to move through the corridor, the corridor defined, at least in part by side walls, the corridor having a first end and a second end; a first door located at the first end, the first door configured to provide selective access between the corridor and a space outside of the corridor; a second door located at the second end, the second door configured to provide selective access between the corridor and a space outside of the corridor; and sensors configured to determine a direction of movement within the corridor, the sensors operatively connected to at least one of the first and second doors to cause at least one of the first and second doors to move to a closed position if any of the sensors detect a movement further than a threshold amount in an undesired direction.

In an example, a device includes a base unit, a cover unit, and a hinge assembly to couple the cover unit to the base unit The hinge assembly is moveable between a folded position and an unfolded position. The hinge assembly includes a channel, an annular holder disposed in the channel, a shaft engaged with the annular holder, and a hydraulic cylinder coupled to the shaft. The hydraulic cylinder is to move the shaft along a longitudinal axis of the shaft, based on a movement of the hinge assembly between the folded position and the unfolded position, to vary an operating torque of the hinge assembly.

A hinge assembly comprise a hinge shaft (102) and a friction gear (108) located around the hinge shaft (102), wherein the friction gear (108) is to rotate around the hinge shaft (102) to create a friction force between the friction gear (108), a washer (106) and a retaining ring (114), generating a damper responsive to closing of a component coupled to the hinge assembly. A hinging method is disclosed.

A drive assembly configured to adjust a motor vehicle closure element including a clutch assembly provided with an input connection and an output connection. The clutch assembly includes a main braking element, configured to brake a movement from the output side, and a freewheel assembly configured to engage the main braking element from movement of the output side and disengage the main braking element by means of a movement from the input side. The brake assembly includes an auxiliary braking element configured to produce a predetermined permanent braking action by means of which the auxiliary braking element acts at least against the movement introduced on the output side, and that the predetermined permanent braking action of the auxiliary braking element has to be overcome to enable the freewheel assembly to disengage.

An overhead door opener for opening and closing an overhead door is disclosed.

A motor is coupled to a shaft and is configured to rotate the shaft to raise and lower the overhead door. The shaft is coupled to the overhead door. The overhead door opener also includes a one-way bearing coupling the motor to the shaft, wherein the one-way bearing is configured to transmit torque from the motor to the shaft, and not to transmit torque from the shaft to the motor.

A damper for fittings for furniture or household appliances has a housing in which a piston connected to a piston rod is guided in a linearly displaceable manner, the piston dividing an interior space in the housing into two chambers, wherein at least one flow channel is formed on or in the piston, which flow channel connects the two chambers to one another, wherein a throttle element is provided, which, in a damping position, keeps the cross-section of the at least one flow channel small when the piston moves in a first direction in order to generate high damping forces, and when the piston moves in the second direction opposite to the first direction, increases the cross-section of the at least one flow channel for reducing the damping forces by a movement of the throttle element.

A furniture drive system for a furniture part that is moveably mounted on a furniture body, includes a mechanical control unit having a pivotally mounted control arm for moving the moveable furniture part and at least one energy store for applying force to the control arm; an electric drive unit configured as a component designed to be separate from the mechanical control unit, and which has an electric motor for the electric motor-powered support of the movement of the moveable furniture part and a driver that can be driven by the electric motor for transmitting a torque of the electric motor to the mechanical control unit; and a damping device for damping the movement of the moveable furniture part. The damping device is arranged in the component of the electric drive unit for damping the movement of the moveable furniture part.
