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.
- GB 2026723 discloses an anti-pinch system for translatory windows such as the windows of a vehicle, i.e. windows which move either vertically or horizontally.
- An anti-pinch system for a pivotable window faces very different problems than a translatory window.
- a pivotable window suffers from load variations due to, e.g., wind or snow, substantially changing the force necessary to operate the window.
- An additional snow or wind load could aid the electric motor in providing the closing force. Consequently, the motor current, which is used as a criterion for the closing force, will not exceed the maximum allowable value until the closing force amounts to the sum of the additional load and the safety margin. This may evidently lead to an obstacle being detected too late to prevent injury or even not being detected at all.
- the force profile of the window is updated according to such an abnormal operation cycle, it may lead to the closure of the window being prevented under normal operating conditions, since the current required under normal conditions exceed the values allowable under the updated profile.
- 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.
- US 5449987 discloses a pivotable window in which the motor current/closing force is monitored while performing a closing operation. If the closing force exceeds a certain threshold, the actuator initiates a reversing operation.
- wind or draft can change the load of a window.
- 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.
- Some pivotable windows such as roof windows may be installed in different roof slopes and consequently the force requirements may be different. As a window ages the resistance (friction) and closing forces also change.
- an actuator for operating a pivot hung or top hung building 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 target of the first closing operation is a fully closed position.
- 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 second threshold is higher than the first threshold.
- the first threshold is lower than a maximum force of the actuator.
- 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 object above is also achieved according to a second aspect by a method of closing a pivot hung or top hung building window using an actuator, the method comprising performing a first closing operation while monitoring a closing force, initiating a first reversing operation when the closing force exceeds a first threshold during the first closing operation, and initiating a second closing operation after the first reversing operation.
- 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.

Description
- 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.
-
GB 2026723 - A pivotable window suffers from load variations due to, e.g., wind or snow, substantially changing the force necessary to operate the window. An additional snow or wind load could aid the electric motor in providing the closing force. Consequently, the motor current, which is used as a criterion for the closing force, will not exceed the maximum allowable value until the closing force amounts to the sum of the additional load and the safety margin. This may evidently lead to an obstacle being detected too late to prevent injury or even not being detected at all.
- Moreover, if the force profile of the window is updated according to such an abnormal operation cycle, it may lead to the closure of the window being prevented under normal operating conditions, since the current required under normal conditions exceed the values allowable under the updated profile.
-
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. -
US 5449987 discloses a pivotable window in which the motor current/closing force is monitored while performing a closing operation. If the closing force exceeds a certain threshold, the actuator initiates a reversing operation. - However there due to various reasons which are explained below, it has shown to be difficult to provide a reliable pinch detection, which also is cost effective. Further it is an object to provide an actuator, which is easy to retrofit to a window that is already installed in a building.
- The final closing movement of a window creates a spike in the closing force needed due compress the gasket between the frame and sash. Different window sizes may use the same actuator drive, but yet require different closing forces.
- As mentioned above, wind or draft can change the load of a window. Snow may change the weight of the window. Likewise, the window may be retrofitted with a blind or a shutter which also changes the weight of the window. Some pivotable windows such as roof windows may be installed in different roof slopes and consequently the force requirements may be different. As a window ages the resistance (friction) and closing forces also change.
- It is an object of the invention to solve or at least reduce the problems indicated above.
- This object is achieved according to a first aspect by an actuator for operating a pivot hung or top hung building 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.
- By closing the window with the force limited to a relatively low first threshold 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. Thus, 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. Thus, there is provided 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.
- In a first possible implementation form of the first aspect 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.
- In a second possible implementation form of the first aspect the target of the first closing operation is a fully closed position.
- In a third possible implementation form of the first aspect 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
- In a fourth possible and implementation form of the first aspect the target of the second closing operation is a fully closed position.
- In a fifth possible implementation form of the first aspect 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.
- In a sixth possible implementation form of the first aspect the actuator is configured to initiate the second closing operation a short period of time after the first reversing operation.
- In a seventh possible implementation form of the first aspect the second threshold is equal to the first threshold
- In an eighth possible implementation form of the first aspect the second threshold is lower than the first threshold.
- In a ninth possible implementation form of the first aspect the second threshold is higher than the first threshold.
- In a tenth possible implementation form of the first aspect the first threshold is lower than a maximum force of the actuator.
- In an eleventh possible implementation form of the first aspect 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.
- In a twelfth possible implementation form of the first aspect 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
- In a thirteenth possible implementation form of the first aspect the actuator is configured to apply the maximum actuator force if needed during the during the second and/or third closing operation.
- In a fourteenth possible implementation form of the first aspect 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 object above is also achieved according to a second aspect by a method of closing a pivot hung or top hung building window using an actuator, the method comprising
performing a first closing operation while monitoring a closing force,
initiating a first reversing operation when the closing force exceeds a first threshold during the first closing operation,
and initiating a second closing operation after the first reversing operation. - In a first possible implementation form of the second aspect 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.
- In a second possible implementation form of the second aspect the method comprises second closing operation is initiated a short period of time after the first reversing operation.
- In a third possible implementation form of the second aspect the method comprises holding the window still for a short period of time between the first reversing operation and the second closing operation.
- In a fourth possible implementation form of the second aspect applying the maximum actuator force if needed during the during the second and/or third closing operation.
- The foregoing and other objects are achieved by the features of the independent claims. Further implementation form forms are apparent from the dependent claims, the detailed description and the figures.

Fig. 1 illustrates a window 1 with top hungrectangular sash 3 with awindow pane 4 therein and a matchingrectangular frame 2.Fig. 2 illustrates a roof window 1 with a pivot hungsash 3 and a matchingrectangular frame 2. The roof window 1 ofFig. 2 is provided with anexterior sun screening 6. A compressible gasket (not shown) is provided between therectangular sash 3 and therectangular frame 2 and the compressible gasket is tightly compressed or deformed between therectangular sash 2 and therectangular gasket 3 when the roof window 1 is fully closed. The roof window ofFig. 1 and ofFig. 2 is provided with an actuator for moving the window i.e. moving thesash 3 between an open position (illustrated) and a closed position. The actuator can be a push-pull (thrust) chain actuator and inFig. 1 the push-pull chain 11 of the actuator can be seen. The actuator itself can be installed in or on theframe 2, or in or on thesash 3. - For illustration purposes, a roof window has been shown in
Figs. 1 and 2 , but it is understood that actuator can be used for any top hung or pivot hung building window.Figs. 3 to 5 show the actuator 10 in the form of a push-pull chain actuator with a push-pull chain 11. However, it is understood that the actuator can be of another type, such as e.g. a spindle actuator. Theactuator 10 comprises ahousing 15 that holds anelectric drive motor 12, a chain magazine, a push-pull chain 11, and aposition sensor 14. The position sensor can e.g. be a rotary pulse generator on theelectric motor 12. Theactuator 10 is provided with anelectronic control unit 50. Theelectronic control unit 50 can be external to theactuator 10 or can be located in in thehousing 15. In one example theanti-pinch controller 50 is embedded in a secure separate processor to provide a failsafe operation. Theelectronic control unit 50 is connected to a source of electric power and configured to control the operation of theactuator 10, i.e. to control the operation of theelectric drive motor 12. Typically, there will be a singleelectric drive motor 12. However, in an embodiment there can be to drivemotors 12 in tandem, as shown inFig. 5 . Theelectric drive motor 12 drives a sprocket (not visible in the drawings) via areduction gear 17. The sprocket engages the push-pull chain 11 and rotation of the sprocket in one direction extends thechain 11 and rotation in the opposite direction retracts the chain. - The push-
pull chain 11 is configured to be able to transmit both tension and pressure and such push-pull chains are well known in the art. When theelectric drive motor 12 is operated in the direction to retract the push-pull chain 11 the incoming chain length is stored in a chain magazine inside thehousing 15. When theelectric drive motor 12 is operated in the direction to extend the push-pull chain 11 the outgoing chain length is removed from the chain magazine. - The force that is applied by the
actuator 10 is in an embodiment measured by monitoring the electric current to theelectric drive motor 12. However, it is understood that the force can be measured by other means, such as for example a strain gauge. -
Fig. 6a shows a graph that illustrates the measured electric current in A to theelectric drive motor 12 over time.Fig. 6b illustrates the measured low-pass filtered current in A to theelectric drive motor 12 over time. The increase of the current towards the end of the time span and thus of the force applied by theactuator 10 to the window and can be an indication of a pinching event. In one example the measured current derivative may be used for enhanced indication of a pinching event. - The
electronic control unit 50 receives instructions, e.g. from a remote control unit (not shown) or from a control panel (not shown) to open or close the window 1 or to move the window 1 to a desired intermediate position, in accordance with the desire of an operator. The instructions can also come from a control system that controls the climate of a building by adjusting the opening of windows in such building. - If the window is open, as shown in
Figs. 1 and 2 , theelectronic control unit 50 may receive an instruction to close the window 1. Theelectronic control unit 50 is configured to initiate a first closing operation upon receipt of such an instruction. - An example of a closing procedure is illustrated in
Fig. 7 . At the start of the closing procedure theelectronic control unit 50 has received in instruction to close the window. Thereupon, theelectronic control unit 50 initiates afirst closing operation 101. During thefirst closing operation 101 theelectronic control unit 50 monitors the force applied to the window by theactuator 10, e.g. by monitoring the current delivered to theelectric drive motor 12. Theelectronic control unit 50 is configured to monitor that the force applied to the window does not exceed a first threshold. The first threshold is preferably a force low enough to avoid injury if a body part, such as the hand or fingers or person is trapped in the window opening, i.e. the opening between thesash 3 and theframe 2. - The
electronic control unit 50 is configured to continue thefirst closing operation 101 until the window 1 is fully closed if the instructions received by theelectronic 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 infigure 7 the instruction received by theelectronic control unit 50 is to close the window 1 completely. - At T1 the force applied to the window exceeds the first threshold (indicate by the interrupted line in
Fig. 6b ) and theelectronic control unit 50 is configured to terminate thefirst closing action 101 and to initiate a first reversingaction 102. The first reversingaction 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 oftime 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. The short period oftime 103 is a brief time. Or a momentary pause allowing a trapped body part to be removed. - The
electronic control unit 50 is configured to initiate asecond closing operation 104 at the end of the first short period oftime 103. Theelectronic control unit 50 is in an embodiment configured to monitor the force applied by theactuator 10 to the window 1 during thesecond closing operation 104 and to terminate thesecond closing operation 104 if the force exceeds a second threshold. The second threshold can be identical to the first threshold, but also be higher or lower than the first threshold. In an embodiment theelectronic control unit 50 is configured to allow the actuator to apply its maximum force during thesecond closing operation 104. -
Fig. 8 is a flowchart illustrating the operation theactuator 10. After the start theelectronic control unit 50 receives instructions to move the window 1 to a target position, e.g. the fully closed position of the window 1. Thereupon, theelectronic control unit 50 initiates thefirst closing operation 101 while monitoring the closing force applied to the window 1. Theelectronic control unit 50 determines whether a first threshold is exceeded during thefirst closing operation 101. If the first threshold is not exceeded theelectronic control unit 50 verifies whether the target position has been reached during thefirst closing operation 101. If the target position has not been reached theelectronic control unit 50 continues with thefirst closing operation 101. When theelectronic control unit 50 detects that target position has been reached the electronic control unit terminates thefirst closing procedure 101. If the target position was the fully closed position thefirst closing procedure 101 ends with the window 1 in its fully closed position. - If the
electronic control unit 50 detects that the closing force exceeds the first threshold during thefirst closing operation 101electronic control unit 50 initiates a first reversingoperation 102 and thereafter maintains the position of the window 1 for a first short period oftime 103, e.g. less than a couple of seconds. - At the end of the first short period of
time 103 theelectronic control unit 50 initiates thesecond closing operation 104. Theelectronic control unit 50 may or may not monitor the closing force during thesecond closing operation 104 and allows theactuator 10 to apply its maximum closing force during thesecond closing operation 104. Theelectronic control unit 50 is configured to verify whether the target position has been reached during thesecond closing operation 104. If the target position has not been reached the second closing operation continues. When the target position has been reached the process ends andelectronic control unit 50 is ready to receive new instructions. - In an embodiment, that can be combined with any of the other embodiments, the
electronic control unit 50 is configured to allow theactuator 10 to apply its maximum force during the very last part of the closing movement towards the completely closed position of the window 1. The very last part of the closing movement is preferably selected so small that it is difficult if not impossible for a person to get his fingers or other body part trapped between theframe 2 and thesash 3, and thus on one hand the risk of a pinching event is small and on the other hand a large force is typically needed for compressing the compressible gasket in this part of the movement. The portion of the closing movement in which the compressible gasket needs to be compressed typically requires a much larger force to be carried out. - In an embodiment, illustrated with reference to
Figs. 9 and10 , theelectronic control unit 50 is configured to perform at least two reversing actions when a respective first and second threshold are exceeded before a third closing operation is carried out with a higher third threshold or without any limit on the force applied to the window. - The closing process is identical to the process described with reference to
Figs. 7 and8 up to the end of the short period oftime 103. During thesecond closing operation 104 theelectronic control unit 50 is configured to verify that the closing force does not exceed a second threshold. The second threshold can be identical to the first threshold or can be lower than the first threshold or can be higher than the first threshold. An example of the first threshold can be 5 kg, with the second threshold being 10 kg. Theelectronic control unit 50 is configured to terminate thesecond closing operation 104 and to initiate a second reversingoperation 105 upon detecting that the second threshold has been exceeded. The second reversingoperation 105, is preferably a small operation with a small stroke, similar to the first reversingoperation 102 and small relative to the maximum movement of the window 1 between its fully closed and fully open position. - The
electronic control unit 50 is configured to hold the window 1 still for a second short period oftime 106 after the second reversingaction 105 has been completed, in order to give the person that has or had a body part trapped time one more opportunity to move this body part away from the window 1. Theelectronic control unit 50 is configured to initiate athird closing operation 107 at the end of the second short period oftime 106. Theelectronic control unit 50 is in an embodiment configured to monitor the force applied by the actuator to the window during thethird closing operation 107 and to terminate thethird closing operation 107 if the force exceeds a third threshold. The third threshold is preferably be higher than the first and second threshold, e.g. 40 kg. In an embodiment theelectronic control unit 50 is configured to allow theactuator 10 to apply its maximum force during thethird closing operation 107. - The process of closing the window in accordance with the embodiment of
Figs. 9 and10 , is identical to the process described in the flowchart inFig. 8 up to and including maintaining the position of the window for the first short period oftime 103. At the end of the first short period oftime 103 theelectronic control unit 50 is configured to initiate thesecond closing operation 104 while monitoring the closing force and to verify that the second threshold is exceeded or not. - If the second threshold is not exceeded, the
electronic control unit 50 verifies whether the target position has been reached. If the target position has not been reached thesecond closing operation 104 continues until the target position has been reached and then the process ends. If the second threshold is exceeded during thesecond closing operation 104 theelectronic control unit 50 performs the second reversingoperation 105 and thereupon maintains the position of the window for a second short period oftime 106. At the end of the second short period oftime 106 theelectronic control unit 50 initiates the third closing operation, preferably without applying a force limit. Theelectronic control unit 50 verifies whether the target position has been reached during thethird closing operation 107 and ends thethird closing operation 107 with the window one in its target position when theelectronic control unit 50 has detected that the window in the target position and then theelectronic control unit 50 is ready to receive new instructions. - The invention has been described in conjunction with various embodiments herein.
