Definitions

  • the present invention relates to a linkage for driving a leaf of a door, window, or the like. Furthermore, the invention relates to a drive for a leaf of a door, window, or the like having said linkage.
  • Door drives and their linkages can be designed in a variety of ways. Depending on the application and desired function, they can be fully automatic, semi-automatic, or have a freewheel function.
  • a door drive that operates with an electromechanical motor and a closing spring.
  • the drive has an output shaft that is connected to the leaf via a power-transmitting linkage with a sliding arm and slide rail.
  • the closing spring ensures that the leaf is securely closed even in the event of a power failure.
  • that the drive has a locking device that interacts with the closing spring and can be switched on/off. In the switched-on position, this locking device keeps the closing spring pretensioned, so that the leaf can be driven exclusively by the electromechanical motor or manually operated.
  • the closing spring is released, so that the leaf closes under the action of the closing spring.
  • the locking device can be released via a fire detector or similar device.
  • the invention is therefore based on the object of creating a linkage for a drive and a drive for a leaf of a door, window, or the like, which, particularly in the event of a fire, allows barrier-free access while complying with the regulations for fire doors and, in particular, complies with the standards DIN 18263-4 and EN 17372 (for fire doors) as well as DIN 18040-1 and DIN 12217 (to ensure barrier-free doors).
  • the linkage should be designed in such a way that existing drives can be easily retrofitted with the innovative linkage, thus ensuring a drive for a barrier-free fire door.
  • a linkage for a drive for a leaf of a door, a window or the like comprising a linkage arm, wherein the linkage arm is configured to be mounted rotatably about the longitudinal axis of an output shaft, a driver which is configured to be connected in a rotationally fixed manner to the output shaft of the drive, and a lock which is configured to be movably arranged between a first position and a second position, wherein in the first position the lock is configured to prevent rotation of the linkage arm about the longitudinal axis relative to the driver (14) (so that the leaf can be driven at least in the opening direction) and wherein in the second position the lock is configured to enable rotation of the linkage arm about the longitudinal axis relative to the driver (so that the leaf can be moved freely at least in the closing direction).
  • the innovative linkage ensures that the link arm is operatively connected to the drive's output shaft in the first locking position, as is usually the case during normal door operation. Since the lock prevents rotation of the link arm relative to the follower (more precisely, it prevents movement of the link arm in the circumferential direction around the longitudinal axis relative to the follower) in the first position, but allows absolute rotation of the link arm around the longitudinal axis, rotation of the link arm inevitably results in rotation of the follower, and thus rotation of the output shaft. In other words, in the first locking position, the link arm is operatively connected to the output shaft or drive.
  • the rotation of the linkage arm in the opening direction of the sash is understood to mean a rotation of the linkage arm around its longitudinal axis in a direction that, if there is an active connection between the linkage and the sash, results in the sash opening.
  • the rotation of the linkage arm in the closing direction of the sash is understood to mean a rotation of the linkage arm around its longitudinal axis in a direction that, if there is an active connection between the linkage and the sash, results in the sash closing.
  • the linkage thus includes a lock which, depending on the position (in interaction with the driver), can activate or deactivate a freewheel.
  • the disclosed linkage or drive allows the leaf of doors or the like to be opened without significant effort in emergency mode (second position of the lock). This function is particularly important for facilities with elderly, weaker, or physically disabled people, such as hospitals, nursing homes, or kindergartens.
  • the linkage according to the invention can ensure that fire protection corridors can continue to be formed in the event of a fire by enabling the door to close safely.
  • the linkage arm comprises a bolt
  • the lock in the first position of the lock, the lock is configured to engage the bolt and (thereby) prevent a relative movement of the bolt (and thus of the linkage arm) in the direction of rotation about the longitudinal axis relative to the driver, and wherein in the second position of the lock, the lock is configured to release the bolt and (thereby) enable a relative movement of the bolt in the direction of rotation about the longitudinal axis relative to the driver.
  • the lock and the bolt are preferably engaged, while in the second position, the lock releases the bolt.
  • automatic operation can take place for a drive on which the linkage is arranged.
  • the bolt could also be attached to the lock.
  • the lock is arranged so as to be movable along the longitudinal axis of the output shaft between the first position and the second position.
  • the lock is configured to be mounted axially displaceably (along the longitudinal axis) on the driver.
  • the lock in the first position of the lock, is preferably not rotatable relative to the link arm about the longitudinal axis, and in the second position of the lock, the lock is rotatable relative to the link arm about the longitudinal axis (both in the opening direction and (at least temporarily) in the closing direction of the sash).
  • the lock in the first position, is secured against rotation relative to the driver (preferably in a form-fitting manner, e.g., via a hexagon or spline).
  • the lock, the driver, and the link arm are arranged rotationally fixed relative to one another.
  • the driver is configured to precede the linkage arm in the direction of rotation around the longitudinal axis in the opening direction of the wing when the lock is in the second position.
  • the lock in the second position thus enables movement of the link arm relative to the driver in the opening direction, free movement of the (door) leaf in the opening direction is ensured.
  • a pedestrian does not have to press the leaf against the driver and thus the drive and possibly a closing spring.
  • the lock is designed to allow rotation of the link arm around the longitudinal axis relative to the driver in the closing direction of the leaf, it can also be ensured that secure closing is guaranteed after any essentially resistance-free passage through the door or the like.
  • the linkage further comprises an actuator configured to move the lock between the first position and the second position, preferably axially along the longitudinal axis of the output shaft.
  • the actuator preferably has an electromagnet configured to move the lock between the first position and the second position using electromagnetic force.
  • the actuator can be designed as an electric lifting magnet, which can, for example, raise and lower the lock axially along the output shaft.
  • the actuator could actuate the lock using a motor, i.e., move it between the first and second positions.
  • the actuator is preferably configured to be fixedly connected to a housing of the drive.
  • the actuator is configured to be fixedly mounted on the housing of a drive unit of the drive, preferably centrally above the output shaft.
  • the actuator is configured to be connected to a control device, preferably a control device of the drive, and to receive a control signal from the control device.
  • the actuator is configured to move the lock into the first position and/or to hold it in the first position when the actuator receives a normal operating signal as a control signal, and/or the actuator is configured to move the lock into the second position and/or to hold it in the second position when the actuator receives an emergency operating signal as a control signal.
  • the driver is configured to be moved into a start position by the output shaft of the drive when the actuator receives the emergency operation signal, wherein in the start position a movement of the linkage arm (or the bolt) in the direction of rotation around the longitudinal axis, in particular in the opening direction of the wing, is enabled relative to the driver.
  • This provides the link arm (especially the bolt) with freedom of movement during emergency operation.
  • movement of the link arm in the opening direction of the leaf can be enabled.
  • This allows the door or similar to be opened during emergency operation without great effort, since the link arm, as long as it is freely movable relative to the driver, does not have to fight against the drive unit of the drive and possibly a mechanical energy storage device.
  • the starting position specifies how far the door (or the link arm) can be opened without resistance.
  • the starting position is preferably selected such that free running of the The rod arm covers an angle of at least 45°, preferably at least 70°, more preferably at least 90°, relative to the closed position of the rod arm in the direction of rotation around the longitudinal axis in the opening direction of the wing.
  • the drive comprises a control device which is configured to provide a control signal to the actuator, wherein the drive can be operated in a normal operation and in an emergency operation, wherein in normal operation a normal operation signal is provided as a control signal and/or wherein in emergency operation an emergency operation signal is provided.
  • the control device can be connected to the actuator via cabling, for example, but non-cabled communication is also conceivable.
  • the actuator is configured to move the lock into the second position upon receipt of the emergency operation signal when the leaf is in the closed position, and in emergency operation when the leaf is in the closed position, the drive device is configured to move the driver into a start position via the output shaft, so that a movement of the bolt in the direction of rotation around the longitudinal axis relative to the driver is enabled.
  • the movement of the lock to the second position and the movement of the driver to the start position occur simultaneously.
  • the control device provides the emergency operation signal to the actuator and the drive device simultaneously.
  • the drive preferably comprises a mechanical energy storage device which is designed to be charged in emergency operation when the leaf is in the closed position. wherein the mechanical energy storage device is connected to the output shaft of the drive device and the driver in emergency operation in such a way that the charging of the mechanical energy storage device causes the driver to move into the starting position.
  • the mechanical energy storage device is typically a (closing) spring, which can be configured as a tension, compression, or torsion spring.
  • a spring arrangement comprising multiple springs is also conceivable.
  • the spring (or the mechanical energy storage device) is connected to the drive unit for driving purposes, at least in emergency operation. Tensioning the spring then causes the driver to move circumferentially around the longitudinal axis in the opening direction of the (door) leaf. Releasing the spring causes the driver to move in the opposite direction.
  • the mechanical energy storage device is preferably designed to immediately begin discharging in emergency operation when the wing is opened, wherein the mechanical energy storage device is connected to the output shaft of the drive device and the driver in such a way that the discharging of the mechanical energy storage device causes the driver to move in the closing direction of the wing, so that the driver causes the wing to move towards the closed position via the rod or the pin of the rod.
  • the spring in the case of a spring as an energy storage device, the spring is initially charged in emergency operation, whereby the driver is moved to the starting position, i.e., it is moved relative to the rod or its bolt in the opening direction of the leaf or door.
  • the rod or its bolt are not affected by this movement, i.e., the energy storage device can be charged in the closed position of the door. Opening the door causes the spring to relax and thus a movement of the driver in the closing direction and towards the rod or its bolt.
  • the rod or bolt is freely movable in the opening direction of the leaf or door. In this respect, the leaf is in freewheeling mode during this period.
  • the rod or bolt is driven in the closing direction by the driver and moved towards the closed position. In other words, the door is brought into the closed position via the driver (and the bolt).

  • the sensor unit can be configured to detect the opening angle of the sash relative to the closed position.
  • the drive can be equipped with a trigger unit configured to provide an opening signal (and thus indicate the opening of the wing) upon detection of a leaf opening, in particular a predetermined (preferably adjustable) opening angle of the leaf or door relative to the closed position (during an opening movement of the leaf), by the sensor unit.
