  • the controller 50 issues a signal to the first cooperating part 22 to carry out the motorized movement that pulls the sash 3 from the nearly closed position to the fully closed position and interlocks the catches 21 and rods 25, thus locking the sash 3 to the frame 2.
  • the sash 3 is configured to be electronically locked and unlocked and to be manually unlockable.
  • Figs. 3 to 5 The different possible positions for the lock are shown in Figs. 3 to 5 .
  • Fig. 3 both the rods 25 and the catches 21 are in their respective locking position. This position will normally only occur when the sash 3 is in its closed position and the sash will accordingly be locked to the frame.
  • the rods 25 have been moved to their unlocking position, by an operator moving the handle 18 against the resilient force towards its unlocking position, and the operator has moved the sash to a slightly open position. When the operator will release the handle, the handle and the rods 25 automatically returned to their locking position so that the second 24 part is ready again for engagement with the second part 20.
  • the controller 50 commands the first part 20 to move the catches 21 to their unlocking position when the sash is open, so that the catches 21 not hinder the sash from returning to its closed position.
  • the controller 50 is configured to move the catch 21 to its unlocking position when the sash 3 is more open than its nearly closed position.
  • the lock is configured so that the first engagement member 21 and the second engagement member 25 automatically assume a position wherein the first engagement member and the second engagement member can engage one another when the sash is in an open position.
  • Figs 1, 2 and 2a is illustrated with a pair of spaced rods 25 and a pair of corresponding catches 21. However, it should be understood that this embodiment will work just as well with a single rod 25 matched to a single catch 21.

  • the second part 24 is provided with a button 29 for manually unlocking the sash, without the need of electrical power being present.
  • the second part is configured to move the catch 33 mechanically from the locking position to the unlocking position, e.g. by spring action when the button 29 is pressed by an operator.
  • the second part is connected to a controller 50.
  • the controller 50 is configured to move the catch 33 from the unlocking position to the locking position when the sash 3 arrives at the nearly closed position from an open position.
  • the slot in the catch 33 engages the rod 35.
  • the catch 33 pivots towards its locking position and thereby interlocks with the rod 35 and pulls the sash 3 to its completely and locked position.
  • Fig 9 shows an example embodiment of a motorized electronic lock 31 that can be used as the second part with the roof window 1 of the embodiment shown in Figs 6 to 8 .
  • the motorized lock 31 includes an electric drive motor 51 with a worm 52 on its drive shaft.
  • the worm 52 drives a wormwheel and through a further reduction gear a linkage 54 that allows the catch 33 to perform a reciprocal pivotal movement between its locking position and unlocking position.
  • the catch 33 is spring loaded towards its unlocking position and the motorized lock 31 is provided with a release mechanism 57 that can disengage the catch 33 from the electric drive and allow the spring loaded catch 33 to move to its unlocking position when the release mechanism 57 is moved against the action of the spring 58 in the direction of the arrow E.
  • the button 29 is connected to the release mechanism 57, via e.g. a link or cable so that a simple pressing on the button 29 by an operator will activate the release mechanism and cause the catch 33 to move to its unlocking position thereby unlocking the sash 3 without any electric power needed to be available.
  • Figs 10, 11 and 11a show another embodiment of the roof window 1 with a different lock construction but otherwise the construction and operation of the roof window 1 of this embodiment is quite similar to the roof window 1 as described above with reference to Figs. 1,2 and 2a .
  • the second engagement member comprises a retractable bolt 45 that projects from the bottom member of the sash.
  • the retractable rod 45 is configured 45 be manually displaceable between a retracted unlocking position and an extended locking position by manipulation of the handle 18.
  • the second part is provided with a mechanism that translates the movement of the handle into a linear movement of the retractable bolt to allow the retractable bolt 45 to move between retracted and extended positions, with the retracted position corresponding to an unlocking position and the extended position corresponding to a locking position.
  • the retractable bolt 45 and the handle 18 are resiliently biased returned to their locking position after the retractable bolt 45 has been moved to its retracted position by an operator manipulating the handle 18.
  • the second engagement member is always ready in its extended position to engage the first engagement member.
  • the first engagement member is disposed at the bottom frame member and the first engagement member comprises a catch 43 that defines a slot for receiving the bolt 45.
  • the first engagement member is electrically displaceable between the unlocking and locking position by pivoting about an axis that is preferably parallel with the longitudinal extend of the frame side members.
  • the controller 50 is connected to the first part and configured to move the catch 43 to its unlocking position when the sash 3 is more open than the nearly closed position.
  • the controller 50 receives a signal from a position sensor (that can be integral part of the linear actuator 40) on the position of the sash.
  • the controller 50 is configured to move the catch to the unlocking position when the sash 3 is more open than the nearly closed position, and the controller 50 is configured to move the catch 43 from its unlocking position to its locking locking position when the sash 3 arrives at the nearly closed position from an open position.
  • the first part is configured to retain the catch 43 in the locking position when the catch is manually moved from the unlocking position to the locking position, e.g. by an operator pulling the sash 3 to the frame.
  • This will be dictated by the controller 50 and the control construct the first part to move the catch to its locking position, thereby interlocking with the retractable bolt 45 and thus locking the sash 3 to the frame 2.
  • the controller 50 is configured to retain the catch 43 in its locking position after the catch 43 is manually moved from the unlocking position to the locking position to ensure that the sash 2 is properly locked to the frame when an operator manually closes the sash 3.
  • the sash 3 can be provided with a seal 49, a described in more detail above.
  • 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.

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 that is applied in the end of the closing movement occurs in the period where the sash is pulled from its nearly closed position to its completely closed position.
  • the gap between the sash and the frame is very small in the likeness of any body parts of an operator being placed between the sash in the frame at this point of time is very small due to the small gap.
  • Another advantage of the disclosed motorized lock is that it allows the user to physically operate the window handle so seamless manual and electric operation is provided.
  • Relatively wide windows can be provided with two locks at the bottom sash member and bottom frame member to ensure proper and hermetic closing of the sash 3 to the frame 2. None of the embodiments above is more preferred than others and the embodiments above all can be combined without any preference to a given combination.
  • the embodiments above have been described with a single actuator placed at one side of the frame, it is however understood that the roof window may just as well be provided with two actuators, one at each side of the frame.
