Abstract:
A gate arm for a swing gate incorporates a release mechanism that releases the gate arm and therefore allows the gate to swing freely about its hinges when inwardly-directed pressure applied to the gate exceeds a threshold level. The gate arm also includes a spring-loaded pivot joint that applies pressure to the gate when the gate is operating normally and is in the closed position, and further works cooperatively with the release mechanism to prevent damage to the operator and gate arm when the gate is forced open.
Abstract:
A spring assembly is provided for an upward acting door that travels on a travel path while opening. The assembly includes a shaft, a torsion spring and a second spring. The torsion spring is connected to the shaft and provides a lifting force for the door throughout the travel path. The second spring is connected to the shaft and provides a lifting force for the door during only a portion of the travel path. In another aspect, a spring assembly is provided for an upward acting door that travels on a travel path while closing. The torsion spring is connected to the shaft and provides a weight supporting force for the door throughout the travel path. The second spring is connected to the shaft and provides a weight supporting force for the door during only a portion of the travel path.

Abstract:
An ejection device for a furniture component moveably housed in or against a furniture body. The ejection device includes a swivellably housed lever. A first castor is attached to a free end of the lever, and a second castor is attached to the lever at a distance from the free end.
Abstract:
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 a drive device (20) for entrance/exit devices for public transit vehicles, comprising a drive unit (22) disposed in and driving a column (24) that rotates about an axis of rotation Z-Z during opening and closing operations, said column opening and closing an entrance/exit device. The drive unit (22) is supported in the vehicle by way of a support component (40) and the support component (40) acts as a counterbearing for a torque of the drive unit (22). A coupling device (72) is disposed between the drive unit (22) and the support component (40), said coupling device facilitating a rotation of the drive unit (22) about the axis of rotation Z-Z when a limit of the torque acting on the drive unit is exceeded.
Abstract:
An article of furniture includes a drive device for moving a movable furniture part. The drive device includes an electric drive unit and a coupling device for at least temporarily transmitting a force of the electric drive unit to the movable furniture part, and the coupling device has a drive and a drive output. Operating between the drive and the drive output are coupling elements by which, in a first operating position, a clamping connection between the drive and the drive output and thus coupling between the drive and the drive output can be produced, and, in a second operating position, the coupling elements are movable into a position in which the drive and the drive output are not coupled.
Abstract:
The invention relates to a damping device with damper arranged on a first part of a piece of furniture or furniture fitting, operable by a second part of a piece of furniture or furniture fitting thus damping a relative movement of both parts, wherein the damping effect of the damper may be deactivated by a switchable coupling switched by means of a preferably manually operated switch body.
Abstract:
A hinge assembly is provided to mount a door to a housing, and includes a housing fixation section (1), a hinge cup (3) pivotally connected to the housing fixation section (1), and a damping mechanism (4) positioned entirely within the hinge cup (3) to dampen movement of the door as it closes on the housing.
Abstract:
An opening and closing member control apparatus for a vehicle includes a driving device adapted to drive an opening and closing member to open and close an opening portion formed at a vehicle body, a sensor provided at a connecting portion connecting the vehicle body with the opening and closing member, the sensor detecting an opening operation and a closing operation of the opening and closing member, and a drive controlling device controlling the driving device to drive the opening and closing member to open or close the opening portion by determining the opening operation or the closing operation of the opening and closing member based on a detection value of the sensor.
