Systems, methods, and apparatus for detecting movable barrier disengagement are provided. A movable barrier operator system includes a motor configured to be coupled to a movable barrier and move the movable barrier, a motor sensor configured to measure a load value of the motor, communication circuitry configured to receive, from a remote control, a state change request to cause movement of the movable barrier, and a processor circuit. The processor circuit is configured to cause actuation of the motor in response to receipt of the state change request, detect, based on the load value, a disengagement between the motor and the movable barrier, and cause a communication to be sent, in response to detecting the disengagement, to a remote server, the communication indicative of motor disengagement.

A rail for guiding a carriage of a furniture door, in which the rail has at least one mounting part. The at least one mounting part can be fastened to a furniture part, which is formed by a side wall of a piece of furniture, and can be releasably connected to a guide part. The guide part has at least one guide for the carriage.

An actuator system comprising a rotatable lock mechanism defining a path for an actuator pin as the actuator is expanded and retracted, wherein the lock mechanism defines an entry passage through which the pin enters as the actuator extends, a guide surface along which the pin travels from the entry passage as the actuator retracts, a locking recess into which the pin is guided by the guide surface, and an exit passage into which the pin is guided as it is caused to leave the lock recess by extension of the actuator and subsequent retraction; whereby a detent surface is provided to prevent the pin returning back into the lock recess when the actuator is extended to cause the pin to leave the lock recess; and whereby the lock mechanism provides a sloping engagement surface for the pin, either side of the entry passage.

A pivotal door assembly includes a door post and a door panel attached to the post via a hinge assembly. The hinge assembly includes a first partial hinge loop extending from the first hinge plate and partially around the door post, and a second partial hinge loop extending from the second hinge plate and partially around the door post. The first partial hinge loop and the second partial hinge loop together provide a clamping of the hinge assembly onto the door post. The first partial hinge loop and the second partial hinge loop slide circumferentially about the door post during pivotal movement of the door panel, and the door panel is pivotal by at least a circumferential amount that is sufficient to expose all hinge-aligned surface portions of the door post for cleaning during pivot. The hinge assembly may include a third partial hinge loop as well.

A rail for guiding a carriage of a furniture door, in which the rail has at least one mounting part. The at least one mounting part can be fastened to a furniture part, which is formed by a side wall of a piece of furniture, and can be releasably connected to a guide part. The guide part has at least one guide for the carriage.

In the roof window, a stationary primary frame (1) with frame members includes two opposing side members (1a), a first secondary frame includes a sash (2) with two opposing side members (2a), and a second secondary frame including an intermediate frame (6) are provided. A lifting device (7) including a spring assembly (7a) acting on a lifting arm (7b) is inserted between the stationary primary frame (1) and the intermediate frame (6). A top hinge arrangement (8) is connected to the primary frame (1) and to the sash (2) and the intermediate frame (6) to define a first hinge axis (?1) at or near a top of the roof window in a first operational condition of the roof window. To provide a second operational condition of the roof window, the hinge arrangement comprises a set of hinges (10) connected to the intermediate frame (6) and to the sash (2) to define a second hinge axis of the roof window in the second operational condition of the roof window. Each of the hinges (10) comprises a frame hinge part, a sash hinge part, and a movement supporting assembly with a linkage mechanism comprising a number of links and joints.

The hinge (10) is intended for a roof window having a frame and a sash, and has a frame hinge part (100) and a sash hinge part (200) configured to assume an angle relative to the frame hinge part (100). Each hinge part (100, 200) has a base plate (110, 210) with a guide track (112, 212) and a link (120, 220), the links (120, 220) being connected to each other at a bearing axle (123). Each link (120, 220) has a first hinged joint (121, 221) to the respective base plate (110, 210) and a sliding joint (122, 222) slidably received in the guide track (212, 112) in the base plate (210, 110) of the other hinge part (200, 100). A pick-up element (130, 230) is connected to the base plate (110, 210) in a second hinged joint (131, 231) and is biased by a spring (140, 240) to act on the sliding joint (222, 122) in the guide track (112, 212), for instance within a predefined angle interval.

A sliding door system includes a sliding door having a first door leaf, a second door leaf and a pivoting mechanism, and a housing for installing into a building wall. The sliding door mounted in the housing is displaceable beyond opposed first and second door openings of the housing. The pivoting mechanism converts a displacement movement of the sliding door into a pivoting movement of the first and second door leaves so that the first and second door leaves expose the first and second door openings respectively in a first position of the sliding door and close the openings in a second position of the sliding door. Deactivating the pivoting mechanism allows the sliding door to be moved beyond the door openings into a third position to service a component of the sliding door and/or to remove the sliding door the first and/or second door opening.

The hinge (10) is intended for a roof window having a frame and a sash, and has a frame hinge part (100) and a sash hinge part (200) configured to assume an angle relative to the frame hinge part (100). Each hinge part (100, 200) has a base plate (110, 210) with a guide track (112, 212) and a link (120, 220), the links (120, 220) being connected to each other at a bearing axle (123). Each link (120, 220) has a first hinged joint (121, 221) to the respective base plate (110, 210) and a sliding joint (122, 222) slidably received in the guide track (212, 112) in the base plate (210, 110) of the other hinge part (200, 100). A pick-up element (130, 230) is connected to the base plate (110, 210) in a second hinged joint (131, 231) and is biased by a spring (140, 240) to act on the sliding joint (222, 122) in the guide track (112, 212), for instance within a predefined angle interval.
