The invention relates to a system for controlling access to a restricted area in a building, which system has a sliding door system and a controller for the sliding door system. The sliding door system has a door frame and a sliding door which can be displaced by a drive unit actuated by the controller. The door frame has a passage region and a wall shell region which accommodates the sliding door in the open position. The sliding door has an end face which points toward the passage region in the open position. The controller has a processor unit and a sensor unit, the sensor unit is arranged on the end face and the processor unit is arranged between the door leaves. A recognition device captures and checks credentials presented by a user. If the credentials are valid, a record is determined in a storage device, in which the credentials are assigned to an opening width (W) of the sliding door, in order to trigger the movement of the sliding door according to said opening width (W). The controller is designed to recognize a gesture made by the user and to actuate the sliding door depending on said gesture in deviation from the opening width (W).

A building sliding door system separates a first building region from a second building region and has a frame structure that has a passage region and a wall shell region. A sliding door is displaced in the frame structure between a closed position and an open position, wherein the wall shell region at least partially receives the sliding door in the open position. An electromechanical drive unit and a control device control the displacement of the sliding door. A fire protection unit has a bracket and, movably mounted on the bracket, a fire protection device made of a material having a defined fire resistance. The fire protection device is horizontally displaceable within the wall shell region with respect to the bracket between a retracted position in which the sliding door is in the open position, and an extended position in which the sliding door is in the closed position.

A dual function door acts as both a pocket door and a hinged swinging door. A first door panel is hingedly attached to a wall for swinging. A first header rail is attached to the top of the first door panel while a second header rail is attached to an appropriate surface at the same height as the first header rail. A second door panel has rollers that slide within the first header rail. The first door panel is positionable so that the first header rail and the second header rail align allowing the second door panel to also slide within the second header rail. The two header rails can be locked in the aligned position.

A building sliding door system has a frame structure with passage, door frame and wall shell regions, and a sliding door is movable in the frame structure along a movement axis between closed and open positions. The wall shell region at least partially receives the sliding door in the open position. A door leaf has an end face facing the passage region and extending transversely to the movement axis. A drive unit and a control device move the sliding door. A display device is arranged in a vertical section of the door and is connected to the control device. The display device has a user interface that extends between a region of the end face and a region of the door across the edge of the door. The control device controls the display device to display information on the door leaf side and/or on the end face.

A motor control system comprises a motor control circuit, a non-transitory storage medium and a processing circuitry. The storage medium is configured to store a current threshold profile that is indicative of a current requirement of the motor control circuit for an operational cycle of a motor. The processing circuitry is configured to adjust the stored current threshold profile based on a change to the operational cycle of the motor (e.g., from standard to non-standard).

A modular wall system with an integrated pocket door includes a frame defining a wall plane and a doorway. The system also includes one or more aesthetic panels connected to at least a portion of the frame so as to cover at least a portion of the wall frame. Additionally, the system includes a support member extending above the doorway and across at least a portion of the wall plane. The support member includes an integrated track that is accessible through one or more access windows integrated into the support member. The system includes a slideable pocket door integrated into the track such that when closed, the pocket door blocks the doorway, and when open, the pocket door is at least partially enclosed behind the one or more aesthetic panels.

A sliding door system includes a rail device with a mounting rail mountable in a building, with a guide rail in which at least two carriages that are connected to a sliding door are held displaceable along a guide axis, and with a plurality of coupling devices with which the guide rail and the mounting rail are releasably connected with one another and which comprise a coupling head connected to the guide rail or the mounting rail, that comprises a coupling plate and a coupling neck and that can be anchored in a coupling opening provided in the mounting rail or the guide rail and which comprises a first opening part with a diameter larger than a diameter of the coupling plate, and a second opening part adjacent thereto with a diameter larger than the diameter of the coupling neck but smaller than the diameter of the coupling plate.

A sliding-door system includes a sliding door, a door frame, and a locking system, wherein in a locked state, a first latch engages in an engagement notch of an anchor body locking the sliding door, and a bolt engages on the anchor body in an engagement region to prevent the anchor body from rotating about a rotational axis. An actuator moves the bolt out of the engagement region to switch the locking system from the locked state into an open state by rotating the anchor body about the rotational axis. A locking system emergency opening function is actuated by applying an emergency activation force to a first door leaf to move a lock substantially perpendicular to a surface of the first door leaf such that the engagement notch is slid out of the engagement region to enable the sliding door to open.

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.

A sliding door system for a building wall includes first and second wall parts having opposite first and second door openings respectively and separated by an intermediate space, first and second door leaves closing the first and second door openings respectively, a door leaf carrier slidable along the intermediate space by a linear guide device and on which the door leaves are pivotably mounted by a pivot mechanism, and a coupling device converting the carrier sliding movement into a rotational movement actuating the pivot mechanism so that the door leaves pivot relative to the door leaf carrier, the coupling device including a slotted component with a slot representing a desired relationship between the sliding movement and the rotational movement and a control lever coupling the slot to the pivot mechanism, and wherein the slotted component is mounted on at least one of the first and second wall parts.
