Abstract: 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.

Abstract: A sliding door includes a bar that is movable in the closing and opening direction of a door leaf the sliding door. When the sliding door is in a closed state, the door separates a first space from a second space. A door frame in which the door is mounted has a bar catch, wherein the bar engages in the bar catch when the door leaf is in the closed state. The engagement can be released by movement of the door leaf, and therefore movement of the bar, in the direction of the normal of the door leaf plane.

Abstract: A system for controlling access to a restricted-access area in a building 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 moved in the door frame between a closed position and an open position by a drive unit. The door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position. A controller is arranged on the sliding door and is communicatively connected to the drive device. The controller is designed to control a movement of the sliding door between the closed position and an open position. A light projection device is arranged in an interior of the sliding door and is communicatively connected to the controller. The light projection device is designed to project status information specified by the controller for a user requesting access to the restricted-access area as a visible light projection onto a projection surface.

Abstract: A building wall module for partitioning a first region from a second region has a frame structure with inner and outer wall panels and lateral fastening devices for connecting the building wall module to a building. In addition, a sliding door system and a secondary door system are integrated in the frame structure, wherein the secondary door system is arranged separated from the sliding door system and can be controlled separately from the control device of the sliding door system. An electrical interface device connects the building wall module to a building system of a building.

Abstract: A sliding door horizontally displaceable between two building wall elements includes a door leaf support frame with an attached door leaf, whereby a distance, perpendicular to a displacement direction of the support frame, between the door leaf and the support frame is changeable between an open position of the door leaf between the wall elements and a closed position of the door leaf in a door opening of one of the wall elements with outer surfaces of the door leaf and wall in alignment. A control element is movable in the displacement direction relative to the support frame and cooperates with a closing edge of the opening to increase and decrease the distance between the door leaf and the door leaf support frame during the closing and opening respectively in a region adjacent the closing edge.

Abstract: A lift system for moving a car along a track in a guided manner. The lift system having a guide rail system, a car and a drive unit arranged on the car. The guide rail system forms a closed track along which the car can be moved between floors when in operation. The drive unit has a motor, a gear wheel system connected to the motor by a shaft and a guide disk. The guide rail system has a pinion system and guide edges spaced apart from one another, which cooperate with the guide disk. When in operation, the motor drives the gear wheel system and the gear wheel system acts on the pinion system in order to move the car along the track in a guided manner.

Abstract: A door system for an elevator installation having an elevator car with a car door arranged to travel in an elevator shaft with shaft doors, wherein the car door is spaced from the shaft doors in a closed position of the door system. A primary pivot spindle is coupled to a pivotable door leaf of the shaft door or the car door and a secondary pivot spindle is coupled to a pivotable door leaf of the other of the car door and the shaft door. A drive unit includes a driven, pivotably mounted shaft to which a first entrainer and a second entrainer are fixed. During a pivoting movement of the shaft, the first entrainer engages a first counterpart element on the primary pivot spindle and the second entrainer engages a second counterpart element on the secondary pivot spindle to effect a pivoting movement of the door leaves.

Abstract: A door system for an elevator installation having an elevator car, the door system including a pivotable first car door leaf mounted at a car door opening and a pivotable first shaft door leaf mounted at a shaft door opening of the elevator installation. At least a part of the shaft door opening is closed by the first shaft door leaf in a closed position thereof and a shaft door plane is formed along the shaft door leaf. At least a part of the car door opening is closed by the first car door leaf in a closed position thereof and a car door plane is formed along the car door leaf. The car door leaf, in an open position thereof, extends through the shaft door plane, or the shaft door leaf, in an open position thereof, extends through the car door plane.
