Definitions

  • the present invention relates to an openable pivot- or top hung roof window with a lock to secure or lock the window in a closed position.
  • Conventional windows of this type are provided with a locking mechanism that is manually operated by a handle for locking the sash in a closed position. Often, the possibility to manually lock the sash in a ventilation position is also provided.
  • a compressible seal or gasket is provided between the frame and the sash in order to seal the sash to the frame in the closed position of the frame. The seal or gasket is typically provided along the complete circumference of the opening in the frame and the gasket requires considerable force to be compressed to the state it has when the sash is closed and sealed to the frame.
  • the locking mechanism needs to provide the force that is needed to compress the gasket to the state it has when the sash is closed and sealed to the frame, so that the locking mechanism can both tighten and lock the sash to the frame.
  • top or pivot hung roof windows that are electronically operated, such as e.g. a roof window provided with an actuator for moving the sash between the closed and open positions and vice versa.
  • the force required to lock the sash and compress the seal has two problems associate therewith.
  • One problem is that the locking mechanism needs to generate the force to compress the seal and the locking mechanism will therefore require some energy form the operator to carry out the locking operation and it is difficult to render the operation of the lock completely smooth when the lock is under the load of the seal.
  • the force and energy needed to operate the lock can reduce the comfort experience of the users.
  • a pivot- or top hung roof window comprising a frame and a sash, the sash being pivotally connected to the frame and pivotally movable relative to the frame between a fully closed position, a nearly closed position where the sash is proximate to the frame and open positions, and a motorized electronically operated lock that comprises first and second cooperating lock parts) that can engage and disengage one another with the first or the second cooperating lock part being attached to the frame and the other cooperating lock part being attached to the sash, the first and second cooperating lock parts being configured to engage one another when the sash arrives from an open position at the nearly closed position, at least the first cooperating lock part being configured carry out a motorized movement that pulls the sash from the nearly closed position to the fully closed position when the first and second cooperating lock parts engage one another.
  • motorized electronically operated lock is operative to urge the sash into the fully closed position.
  • the action of closing and locking the window is facilitated and rendered more comfortable since he/she needs to do no more than to bring the sash in the nearly closed position, where after the window will automatically close and lock.
  • actuators that move the window in the range of open positions it is often not possible to close the sash against the frame with sufficient force, and thus the provision of a motorized lock renders the complete operation of opening, closing and locking automatic.
  • the openable window further comprises a first sensor or switch configured to cause a first signal to be transmitted to the motorized electronically operated lock to pull the sash from the nearly closed position to the fully closed position when the sash reaches the nearly closed position from one of the open positions.
  • the openable window further comprises a first sensor or switch configured to cause a first signal to be transmitted to the motorized electronically operated lock to pull the sash from the nearly closed position to the fully closed position when the first and second lock part engage one another.
  • the motorized electronically operated lock is configured to lock or latch the sash after or when drawing the sash to the closed position.
  • the motorized electronically operated lock is configured to actively move the sash from the fully closed position to the nearly closed position and to release the sash by disengaging the first and second lock parts upon receipt of a control signal, or wherein the motorized electronically operated lock is configured to allow the sash to move from the fully closed position to the nearly closed position and to release the sash by disengaging the first and second lock parts upon receipt of a control signal.
  • the window comprises a controller operatively connected to the motorized electronically operated lock, the controller being configured to send a control signal to the motorized electronically operated lock to pull the sash from the nearly closed position to the fully closed position when the controller receives a signal form the sensor indicating that the sash has reached the nearly closed position from one of the open positions.
  • the openable window further comprises a compressible seal interposed between at least a portion of the sash and a portion of the frame, the compressible seal being at least partially compressed when the sash is in the fully closed position.
  • the first cooperating lock part is configured to provide a pulling force for pulling the sash from the nearly closed position to the fully closed position that is sufficiently large to compress the compressible seal.
  • the compressible seal is substantially uncompressed in the nearly closed position of the sash.
  • the first cooperating lock part comprises a moveable part that is operated by a motor or actuator, preferably under command from the controller, to move between a first position and a second position, the first position placing a first engagement member of the first cooperating lock part in a position to engage a second engagement member of the second cooperating lock part when the sash is in the nearly closed position, and the second position placing the first cooperating lock part in a position where the sash is fully locked when the second engagement member is engaged with the first engagement member.
  • the sash actuator operatively connected to the sash and configured to move the sash between the nearly closed position and the open positions, preferably under command from the controller.
  • the electric drive motor operably connected to a revolution-counter, the revolution counter being connected to the controller and the controller being configured to determine the position of the sash on the basis of a signal from the revolution counter.
  • the controller monitors the electrical current supplied to the electric drive motor and wherein the controller is configured to determine that the sash has reached an end position, such as e.g. the nearly closed position and/or a fully open position when the current exceeds a threshold, the controller further preferably being configured to store the determined position relative to the position derived from the signal from the revolution counter.

Since the pegs 25 are secured in the dead end of the sloping slot 23, the sash 3 is also locked in this position. When the sash 3 is to be opened the controller 50 will upon receiving a corresponding control signal activate the motor or linear actuator 72 to move to the right (right as in Fig.
  • Fig. 13 is diagrammatic side view of an example embodiment of the top or pivot hung roof window 1.
  • the first cooperative lock part 22 is arranged in the sash and the motor or actuator 27 is coupled to the handle 18.
  • the motor or linear actuator 27 is also operatively coupled to a first engagement member 23 and configured to move the first engaging member 23 as shown by the double-sided arrow under command from the controller 50.
  • the first engaging member 23 is configured as a member with a triangular cross-section.
  • the second cooperating lock part 24 is provided with a second engaging member 25 that is secured to the frame 2.
  • the second engaging member 25 also has a triangular cross-section and the respective inclined surfaces of the first and second engaging members 23, 25 allow for the locking of the sash and for pulling the sash 3 from a nearly closed position to a fully closed position, similar to the operation described with reference to the embodiments above.
  • Fig. 14 is a diagrammatic side view of an example embodiment of the top or pivot hung roof window 1.
  • the first cooperating lock part 22 is secured and preferably partially integrated into the frame 2.
  • the first cooperating lock part 22 includes a motor or linear actuator 27 that is operatively connected to a spring-loaded catch 23 that protrudes from the frame 2 in order to be able to engage the latch 25 of the second cooperating lock member 24 that is provided in and preferably integrated into the sash 3.
  • the latch 25 is operatively connected to the handle 18, so that rotational movement of the handle 18 will cause a translative moment of the latch 25 in the direction of the double-sided arrow in Fig. 14 for manually disengaging the latch 25.
  • the operation of the roof window 1 according to this embodiment is illustrated in Figs. 16 and 17 .
  • Fig. 15 is a diagrammatic side view of an example embodiment of the top or pivot hung roof window 1 with a motorized lock 20 as shown in Fig. 11 .
  • Fig. 16 shows the roof window of Fig. 14 with the sash 3 in the nearly closed position and with the first cooperating lock part 22 having engaged the second cooperative lock part 24 by the latch 25 being caught by the catch 23.
  • the next step of the locking procedure is the activation of the linear actuator motor 27 that pulls the catch 23 and thereby the latch 25 and the sash 3 towards the frame 2 to thereby close and lock the window 1 as shown in Fig. 17 .
  • the sash actuator 40 is configured to automatically disengage the sash 3 when the sash 3 is manually moved.
  • the top or pivot hung roof window 1 is provided with means for protecting operators or other persons in the vicinity of the roof window 1 to get body parts stuck in the window.
  • the roof window 1 is provided with sensors that detect the amount of force that is applied to the sash 3 by the respective actuators or motors and the controller 50 is configured to determine on the basis of the magnitude of the force, the time during which the force has been applied and the position of the sash 3 whether an object is stuck in the roof window 1. If such an event has been determined the controller 50 will stop the operation of the actuators and motors or even reverse the last part of the movement of the sash 3.
  • One further advantage of the disclosed motorized lock is that the high closing force of 10-50 Kg is applied in the end of the closing movement, thereby preventing large force exposure to body parts stuck between the frame and sash during the open positions.
  • Another advantage of the disclosed motorized lock is that it allows the user to physically operate the window handle so straightforward manual and electric operation is provided.
