Abstract: The invention relates to a door drive device (11) for driving a door leaf (18) of a door (10), comprising a traction mechanism (13) designed in particular as a rope drive, the mechanism comprising a traction means monitoring device (28) for monitoring a breakdown of a traction means (Z1, Z2). In order to provide a simple design, which can be installed with particular ease, yet ensures safe operation, the traction means monitoring device (28) consists of mechanical blocking devices (150, 160) acting in opposing door movement directions and blocking when the traction means tension of an associated traction means (Z1, Z2) decreases and a load monitoring device (78) for a motor drive assembly (49) for load interruption when one of the blocking devices (150, 160) blocks.

Abstract: A retaining arrangement is provided with at least one light-barrier fastening device for fastening the light-barrier element on the retaining arrangement, and with at least one first door-fastening device, for fastening the retaining arrangement on an element of a first type of door, and also with at least one second door-fastening device for fastening the retaining arrangement on an element of a second type of door, and/or with a floor-fastening/ground-fastening or wall-fastening device, for fastening the retaining arrangement on the floor/ground or a surrounding wall and/or on an element of an undetermined type of door.

Abstract: A light barrier housing is provided in a light barrier for monitoring an automatically driven architectural closure. In order to reduce mounting work, a cable connection having at least one clamped connection is provided.

Abstract: A shaft operator assembly for moving a door assembly which includes a movable door leaf and a door shaft attached to the door leaf for common movement together. A shaft connecting unit includes a shaft connecting element and a connecting plate element and connects a driven member of the shaft operator assembly with minimal space requirements to the door shaft. The connecting plate element, which can be secured to or integrally configured with the driven member, is relatively thin to permit the jack shaft operator and connecting plate element to be shifted into a fitted position even where little space is available. The shaft connecting element is mountable non-rotatably on the door shaft and includes an axial opening extending through the shaft connecting element for receiving the door shaft.

Abstract: The invention relates to an emergency release device for a building closure operator for decoupling a motorized building closure from a motor operator assembly under emergency conditions. To diminish the risk of injury by free-fall of a decoupled building closure wing by a simple and cost-effective design the invention proposes providing a safety or securing unit which safeguards or secures the emergency release device against unintentional or unauthorized actuation.

Abstract: A separating device for a door leaf that is moveable overhead has a coupling element movable between a coupling position, in which the coupling element couples an output element of the drive device to the structural component, and a freewheeling position, in which the output element of the drive device is decoupled from the structural component. A locking member is provided which is movable between at least one release position, in which the locking member allows a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts a movement of the coupling element into the freewheeling position. The locking member can be coupled to the drive device.

Abstract: A door driving-mechanism torque transmission (20, 40, or 50) for transmitting torque from a door-driving motor assembly, especially a geared motor (36), to a shaft (33) connected to a door panel (31). A driving component rotates around an axis and can be engaged with the door-driving motor assembly. A driven component rotates around another axis and can be engaged with the shaft. A bearing assembly accommodates both components mounted on separated axes of rotation. There is a coupling connection (2) between both components. The object is to promote smooth operation and decrease frequency of repair. The bearing assembly (4 or 51) is accordingly provided with a driving-component bearing half (5 or 52) that the driving component (1) is mounted on and with, separated therefrom, a driven-component bearing half (6 or 53) that the driven component (3) is mounted on. The bearing halves (5 & 6 or 52 & 53) are connected elastically for the purpose of attenuating torsional vibrations and impacts.

Abstract: The invention relates to an emergency release device (4) for a building closure operator (2) for decoupling a motorized building closure from a motor operator assembly (6, 9) under emergency conditions. To diminish the risk of injury by free-fall of a decoupled building closure wing by a simple and cost-effective design the invention proposes providing a safety or securing means (24) which safeguards or secures the emergency release device (4) against unintentional or unauthorized actuation.

Abstract: The invention relative to a shaft operator assembly (8) for powering a door (2) comprising a movable door leaf (4) and a door shaft (6) geared to the door leaf (4) for common movement, including a shaft connecting means (20) for connecting a driven member (35) of the shaft operator assembly (8) to the door shaft (6).

Abstract: The invention relates to a locking device and a door-drive device comprising a locking device for a door which can be secured against opening by unauthorized persons using force from the exterior. The locking device has a lever element consisting of two lever arms which pivot about a first pivoting shaft. A connecting element is hinged to the first lever arm for connecting the door and the second lever arm which has an engaging device.
