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.

An arrangement for guiding a movable furniture part includes a guide rail to be fastened to the fixed furniture part, a guide device mounted movably on the at least one guide rail and in particular can be coupled to the movable furniture part, and a first cable having a first end to be secured to the fixed furniture part and a second end to be coupled to the guide device. A securing device can secure the first cable to the fixed furniture part, and the securing device has a mounting device designed such that the first cable is mounted so as to be movable relative to the fixed furniture part to a limited extent at least in the event of overload.

The disclosure relates to a drive arrangement for a flap of a motor vehicle, comprising a linear drive for producing drive movements and comprising a transmission arrangement, which is coupled to said linear drive, for transmitting the drive movements, a compensating arrangement being provided which couples two drive elements of the drive arrangement to each other in terms of drive, and, when a limit load between the two drive elements is exceeded, the compensating arrangement permitting a guided compensating movement between the two drive elements. It is proposed that the transmission arrangement provides the compensating arrangement.

An automatic disengaging linkage system including a housing operably connectable to a garage door trolley and a garage door arm. The housing can define a main bore configured to receive a portion of the garage door arm. A ball can be receivable in a ball bore defined in the housing. A biasing member can be configured to force the ball in engagement with the garage door arm or an arm pin associated with the garage door arm. The ball or the biasing member can be configured to disengage with the garage door arm with the housing when a predetermined pulling force is applied to the housing. The garage door arm can automatically be disengaged with the housing upon encounter a sufficient pulling force that retracts the ball into its ball bore thereby allowing the garage door arm to move freely out from the main bore.

The present invention relates to a hinge device for a rotating door, and more particularly, to a hinge device for a rotating door, which is mounted on the rotating door so that the door can be opened and closed while rotating in various ways. The hinge device for the rotating door of the present invention rotates by an external force and then rotated in a free stop manner at a certain section, and automatically rotates in a reverse direction at a section where the hinge device reversely rotates after free stop rotation.

The invention comprises a door closer (1), a slide rail (3) and an arm (2). The arm is connected to the door closer (1) and to the slide rail (3). The slide rail is provided with a hold open device (4) in order to keep a door open. The arm (2) comprises an outer arm (8A, 9A) and an inner arm (8B, 9B). The inner is situated partly inside the outer arm in a sliding manner. The arm (2) also comprises a spring arrangement (11) in order to hold the inner arm (8B, 9B) in a normal position in the outer arm (8A, 9A), and a release device (10A, 10B). The release device is arranged to release the inner arm (8B, 9B) from its normal position when an external force being strong enough to active a release of the release device (10A, 10B) drives the inner arm (8B, 9B) out from the outer arm (8A, 9A).

The present invention relates to a hinge device for a rotating door, and more particularly, to a hinge device for a rotating door, which is mounted on the rotating door so that the door can be opened and closed while rotating in various ways. The hinge device for the rotating door of the present invention rotates by an external force and then rotated in a free stop manner at a certain section, and automatically rotates in a reverse direction at a section where the hinge device reversely rotates after free stop rotation.

The disclosure relates to a drive assembly of a closure element assembly of a motor vehicle, wherein the drive assembly comprises a drive motor and, connected to the drive motor, a feed gearing for generating linear drive movements along a geometrical drive axis, wherein the drive motor and the feed gearing are arranged in a drive train of the drive assembly and the drive train extends between two mechanical drive connections for putting out drive movements and wherein the drive assembly comprises a brake for braking at least a portion of the drive train. It is proposed that the brake is designed such that the braking action of the brake is reduced with an increasing load in the drive train.

Certain embodiments relate to a hold-open assembly for a door closer including a pinion operable to rotate in a closing direction and an opposite opening direction. The hold-open assembly includes a ratchet wheel, a pawl, a controller, and a driver. The ratchet wheel is structured to be mounted to the pinion for joint rotation therewith. The pawl has an engaged position in which the pawl prevents rotation of the ratchet wheel in the closing direction, and has a disengaged position in which the pawl permits rotation of the ratchet wheel in both the opening direction and the closing direction. The controller is operable to determine a release condition and is configured to transmit a release signal in response to determining the release condition. The driver is configured to move the pawl from the engaged position to the disengaged position in response to the release signal.

A module for a modular, motorized drive system, in particular for doors, wherein the modular system is designed such that a number of modules arranged linearly one behind the other along a longitudinal axis of the modular system form a functional group of the drive system is provided. The modular system includes at least one of a number of latching elements on a front side of the module orthogonal to the longitudinal axis and a number of receiving elements, which are complementary to the latching elements, on a rear side of the module orthogonal to the longitudinal axis and opposite the front side, wherein the receiving elements are designed to form a mechanical connection to the latching elements of a further module which is arranged with its front side parallel to the rear side of the module.
