Definitions

  • the invention relates to a drive for a closing device of a building opening according to the preamble of claim 1.
  • a locking device of the type mentioned is from the DE 201 18 594 U1 known.
  • a mechanical energy storage is provided in the form of a force accumulator, which is designed as a steel rod which is mounted vertically vertically movable.
  • the system has an electric motor with a driven-side dog clutch for coupling to the winding shaft.
  • a compression spring holds the jaw clutch in coupling position, so that the winding shaft is rotated by the electric motor in rotation.
  • the output-side part of the dog clutch has a stub shaft, the free end of an adapter is rotatably disposed, which in turn is rotatably connected to the winding shaft.
  • the compression spring is pushed onto the stub shaft of the dog clutch and clamped between the adapter and the output side part of the dog clutch.
  • the system further includes a decoupling cable in the form of an actuating cable to bring the output side portion of the dog clutch against the force of the compression spring in the decoupled position of the electric motor and winding shaft.
  • a torsion spring is disposed on the opposite side of the drive shaft, which is rotatably mounted with its one end with respect to the winding shaft and engages with its other end to a separate drive plate which rotatably connected to the winding shaft connected is.
  • a torsion spring In the decoupled state of the drive unit exercises the Torsion spring a moment on the winding shaft, which counteracts the resulting from the weight of the curtain moment while keeping the curtain in the respective position still.
  • a rotation of the winding shaft is blocked by the actuator in the engaged state of the dog clutch.
  • the dog clutch If the dog clutch is pulled from the engaged to the disengaged state in the event of a power failure via the decoupling cable or the control cable, it should be easy to raise the curtain, since the torsion spring prevents the curtain from lowering under the effect of its own weight. In the event of a power failure, the curtain remains in the respective position because the winding shaft is blocked by the actuator.
  • a disadvantage of this known closure system is that it is possible only by an intervention of the user to manually raise the gate. To do this, first pull on the decoupling cable to transfer the dog clutch to the disengaged position. Only then can the roller shutter, but still manually, be moved upwards. Valuable time is lost, in particular in a danger trap, since first a manual unlocking of the clutch is necessary in order to then manually move the gate into the open position by the user.
  • the electromotive drive is usually made of a tubular motor, which is coupled to an electromagnetic Anlagenstrombremse.
  • the residual current brake is activated and thus effective as long as the electric motor is not actuated. It holds the closing device in the desired position between an open and closed position during operation.
  • a fire protection drive with a drive motor for rolling up a curtain, a working current brake for braking the curtain and with a connectable with the working current brake motor known.
  • the voltage generated by the brake motor is used when unrolling the curtain to activate the working current brake.
  • the brake motor has an output voltage corresponding to the operating voltage of the operating current brake.
  • the working current brake is deactivated.
  • the curtain for example, a smoke screen curtain, by gravity wound, which is rotated via the drive shaft, the transmission and the drive shaft of the DC motor.
  • the brake motor is operated in this case as a generator and generates the operating voltage of the working current brake.
  • the smoke protection curtain is thus lowered in a danger trap in the closed position.
  • roller shutter drives when shut down curtains in case of danger, especially in building fires, it is difficult for emergency services, such as fire, etc., to get into the building interior. Similarly, it is difficult for people inside the building to get outside.
  • the invention is therefore based on the object to provide a drive according to the preamble of claim 1 is available, which automatically allows an opening of the closing device or the blind with a stationary closing device or in a stationary curtain in case of power failure.
  • the drive according to the invention for a closing device of a building opening of the aforementioned type has a drive motor for moving the closing device between an open and closed position and a working current brake in order to hold the closing device in a position.
  • the drive has a mechanical energy store, which automatically moves the closing device into the open position in an energized state of the working current brake.
  • the working current brake holds the locking device in a rest position, for example in a closed position.
  • a danger trap or for maintenance purposes in which the working current brake is de-energized, it is now possible by the force of the mechanical energy storage to move the locking device automatically in the open position.
  • people, such as emergency services quickly get into the interior of a building.
  • persons On the other hand, it is possible for persons to pass through the closing device from inside to outside or to be able to pass under the closing device.
  • Closing devices with working current brakes without such mechanical energy storage slide due to the dead weight of the closing device in the case of no-current working current brake down or remain in the closed position when the working current brake is de-energized. This is true even if the working current brake is supplied separately from the operating voltage of the drive in another circuit with voltage and the working current brake is de-energized.
  • a coupling between the motor and winding shaft according to the invention is not necessary. Rather, according to the invention, the roller shutter or the curtain is automatically moved in the event of a power failure without intervention of the user in the open position.
  • the mechanical energy storage is designed as an elastic return element, for example as a torsion spring or coil spring or as a non-self-locking thread with disc spring or leaf spring or the like. Due to the design of the mechanical energy storage as an elastic return element, a particularly simple assembly, for example, the torsion spring in the drive of the locking device is possible. The compactness of the torsion spring has an advantageous effect on the space to be used. In addition, the torsion spring can be pushed onto a winding shaft.
  • the closing device is arranged up and unrolled on a winding shaft, wherein the restoring element, in particular the torsion spring, with its one end is non-rotatably connected with respect to the closing device with a housing of the drive and with his / her other end on or in the winding shaft attacks.
  • the design of the mechanical energy storage as a hydraulically and / or pneumatically assisted return element offers the advantage that a reliable and durable energy storage is ensured due to the low wear.
  • the performance and the force characteristics are very variable adjustable, whereby the different sizes of the closing devices and the associated different power requirements for the drive can be optimally implemented by a single system or adapted to each other.
  • the one end of the elastic restoring element in particular the torsion spring
  • the other end acts on a rotatably mounted on or in the winding shaft arranged driver on which also attacks the drive motor.
  • the mechanical energy store is designed as a separate component. This is particularly advantageous in terms of a simple and safe installation, since the fitters do not interfere with the assembly of the drive motor in a biased restoring element, such as a spring or a pneumatically or hydraulically assisted element or handle it, so that therefore a risk of injury counteracted.
  • a biased restoring element such as a spring or a pneumatically or hydraulically assisted element or handle it
  • the rotationally fixed with respect to the closing device formed end of the elastic return element is held on a building side bearing and engages with its other end to the winding shaft.
  • the drive motor and the elastic return element engage on opposite sides of the common carrier. This connection increases the number of components reduced, since no further drivers are provided for connection to the winding shaft. In addition, friction losses can be avoided by additional components, whereby the efficiency of the drive is increased.
  • the drive has a first and second driver, which are arranged at a distance from one another on or in the winding shaft, wherein the drive motor acts on the first driver and the elastic return element on the second driver.
  • This advantageous embodiment of the invention is particularly useful for long winding shafts.
  • a practicable variant of the invention provides that one end of the elastic return element is held on a building-side bearing and engages the elastic return element with its other end to the winding shaft.
  • the motor engages via an output shaft of the drive to the first driver.
  • the restoring force of the mechanical energy accumulator, in particular the spring constant of the elastic return element is designed such that the operating current brake holds the locking device against the force of the elastic return element in one position.
  • the working current brake thus holds the closing device in the respectively approached position, that is to say the closing device remains in its respective position.
  • the elastic return element is stretched due to the connection to the housing and to the winding shaft with a driver and acts in normal operation against the force of the working current brake.
  • the elastic return element can also be biased. This has the advantage that the upper end position does not have to be adjusted so precisely, since the force of a preloaded spring in the end position still has a surplus of force.
  • the spring constant is advantageously designed such that the elastic return element, of course, does not pull the closing device upwards against the force of the working current brake during normal operation.
  • the force of the elastic return element is in the case of a normally de-energized working current brake dimensioned sufficiently large to move the locking device in the open position.
  • the drive is designed as a tubular drive.
  • Such tubular drives are standardized and are therefore often preferred for drives with special dimensions and special shapes.
  • the compactness of the drive saves storage and transport costs.
  • the working current brake by an externally operated device for example by a key switch and / or code input and / or by a controller and / or by an external signal generator, such as a smoke detector, de-energized is switchable.
  • an externally operated device for example by a key switch and / or code input and / or by a controller and / or by an external signal generator, such as a smoke detector, de-energized is switchable.
  • emergency personnel can switch off by means of externally operated key switch or by code input the working current brake to get into the interior of a building.
  • a control for Stromlosbling the working current brake is also for example for maintenance of advantage.
  • the external signal generator such as an alarm system
  • a de-energized state may be intentionally achieved, such as for maintenance or testing purposes or unintentionally, such as in a hazard or the like.
  • the Hästrombreme could be de-energized and the locking device would automatically moved to the open position.
  • an external Signalers are automatically activated.
  • a signaling on a telephone for example by an SMS or an automatic call, is conceivable.
  • the closing device is designed as a sunshade, awning, textile curtain, Venetian blind, smoke curtain, roller shutter, roller shutter, garage door, Feuerschutzbehang, room divider or the like.
