Definitions

  • This disclosure relates to an electrically pivotable window and the electrical drive of such window. Particularly, the disclosure relates to anti-pinch sensing and control of the window.
  • EP 2754820 discloses a pivotable window with an actuator on each side. Each actuator has a safety strip 9 on the actuator housing to detect an object entrapped between the actuator housing and the window frame.
  • EP 1441100 discloses a pivotable window without pinch detection. Instead, the closing movement is performed stepwise to increase the attention of the person nearby and to limit the risk of pinching.
  • Different window sizes may use the same actuator drive, but yet require different closing forces.
  • the final closing movement of a window creates a spike in the closing force needed due compress the gasket between the frame and sash.
  • Wind or draft can change the load of a window.
  • Some pivoatable windows such as roof windows may be installed in different roof slopes and consequently the force requirements may be different. Further snow may change the weight of the window.
  • the window may be retrofitted with a blind or a shutter which also changes the weight of the window. As a window ages the resistance (friction) and closing forces also change.
  • an actuator for operating a pivot hung or top hung window the actuator being adapted to perform a first closing operation while monitoring a closing force applied by the actuator, the actuator being adapted to initiate a first reversing operation upon the closing force exceeding a first threshold during the first closing operation, and the actuator being configured to initiate a second closing operation after the first reversing operation.
  • a pinching event or entrapment event can be detected without large force being applied to the trapped or pinched object.
  • the reversing action allows the trapped or pinched object to be removed, before the second closing action takes place.
  • the second closing action can be carried out with a higher threshold allowing a larger force to be applied to the window. This larger force may be necessary due to excessive friction or wind conditions.
  • proper closing of the window is ensured whilst the risk of injury to e.g. fingers or other body parts of a person is reduced since the person will have a chance to remove their hand, fingers or other body part during the reversing operation.
  • an enhanced entrapment detection which does not terminate the closing operation due to false pinching signals caused, e.g. by strong winds. Further, it is ensured that the window closes while allowing trapped objects to escape.
  • the actuator is configured to monitor the closing force applied by the actuator during the second closing operation, configured to initiate a second reversing operation upon the closing force exceeding a second threshold during the second closing operation and configured to initiate a third closing operation after the second reversing operation.

  • the first reversing operation has a magnitude that is small compared to a complete movement of the window between a fully open and a fully closed position
  • the target of the second closing operation is a fully closed position.
  • the second reversing operation has a magnitude that is small compared to the complete movement of the window between a fully open and a fully closed position.
  • the actuator is configured to initiate the second closing operation a short period of time after the first reversing operation.
  • the second threshold is equal to the first threshold
  • the second threshold is lower than the first threshold.

  • the actuator is configured to hold the window still for a short period of time between the first reversing operation and the second closing operation.
  • the actuator is configured to hold the window still for a short period of time between the second reversing operation and the third closing operation
  • the actuator is configured to apply the maximum actuator force if needed during the during the second and/or third closing operation.
  • the actuator is configured to allow the actuator to always allow use of the maximum actuator force when the opening of the window is smaller than a first opening threshold.
  • the method further comprises monitoring the closing force applied by the actuator during the second closing operation, initiating a second reversing operation when the closing force exceeds a second threshold during the second closing operation and initiating initiate a third closing operation after the second reversing operation.
  • the method comprises second closing operation is initiated a short period of time after the first reversing operation.
  • the method comprises holding the window still for a short period of time between the first reversing operation and the second closing operation.

  • the electronic control unit 50 monitors the force applied to the window by the actuator 10, e.g. by monitoring the current delivered to the electric drive motor 12.
  • the electronic control unit 50 is configured to monitor that the force applied to the window does not exceed a first threshold.

  • the electronic control unit 50 is configured to continue the first closing operation 101 until the window 1 is fully closed if the instructions received by the electronic control unit 50 are to close the window 1 completely. If the instructions are to close the window to a desired position, for example a ventilating position in which the window is slightly open the procedure lasts until the desired position is reached. In the example in figure 7 the instruction received by the electronic control unit 50 is to close the window 1 completely.
  • the first reversing action 102 is preferably a relatively small movement, i.e. relatively small compared to a full movement of the window 1 between its fully open position and fully closed position.
  • the first reversing action should 102 be large enough for a person to move a trapped body part away from the window 1.
  • the electronic control unit 50 is configured to hold the window still for a first short period of time 103 after the first reversing action has been completed, in order to give a person that has a body part trapped time to move this body part away from the window 1.
