Description

TECHNICAL FIELD

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.

BACKGROUND ART

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.
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 from 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.

SUMMARY OF THE INVENTION

According to a first aspect the above problems are at least partially solved and other objects and advantages are obtained by the provision of a pivot- or top hung roof window, the 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, the motorized electronically operated lock being operatively connected to a handle provided for manual locking and unlocking of the sash.
By providing a motorized lock that is configured to pull the sash from the nearly closed position to the closed position, the task of the final closing and locking of the sash does not need to be carried out by an operator or by an actuator that moves the window in the range of open positions. Instead, motorized electronically operated lock is operative to urge the sash into the fully closed position. For the operator, 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.
According to one aspect 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.
According to another aspect 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.
According to another aspect the motorized electronically operated lock is configured to lock or latch the sash after or when drawing the sash to the closed position.
According to another aspect 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.
According to another aspect 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.
According to another aspect 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.
According to another aspect 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.
According to another aspect the compressible seal is substantially uncompressed in the nearly closed position of the sash.
According to another aspect 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.
According to another aspect the roof window is not provided with a sash actuator, such that all opening movement between the nearly closed position and the open positions is executed manually by means of the handle.
According to another aspect the handle is provided for manually moving the sash between the fully closed and open positions.
According to another aspect the first cooperative lock part or the second cooperative lock part further comprises a motorized engagement member configured to move the lock part concerned between an engaged position and a disengaged position, preferably in response to a signal.
According to another aspect the first engagement member of the first cooperating lock part and the second engagement member of the second cooperating lock part are configured to engage automatically when the sash arrives at the nearly closed position from one of the open positions.
Further objects, features, advantages and properties of the pivot or top hung roof window according to the invention will become apparent from the detailed description.

DETAILED DESCRIPTION

Figs. 1 and 2 show perspective views of an openable top hung roof window generally indicated by reference numeral 1. The roof window comprises a rectangular frame 2 defining an opening and a rectangular sash 3 matching the opening. The sash 3 is connected to the frame 2 at the top portion of the frame 2 by suitable hinge 4 that is arranged at the top of the roof window 1. The frame members and the sash members can for example be wooden members, metal profiles, plastic (polymeric) material members or combinations thereof. Two arms 8 connect the sash 3 to the hinge 4. The sash 3 includes a window pane 11, such as for example double glazing, and can undergo a pivotal movement relative to the frame 2 about the hinge 4 as indicated by the arrow B in Fig. 1 between a closed position and open positions. The sash 3 is via a link member 5 connected to an elongated member 6 in such a manner that the elongated member 6 will undergo an axial movement as indicated by the arrow A when the sash 3 undergoes a pivotal movement relative to the frame 2.
The elongated member 6 is axially displaceable in the frame 2 and biased in its movement by a resilient biasing means such as for instance a helical spring 7 that encircles a portion of the elongate member 6 for balancing the sash 3 in various open positions thereof. It is apparent to those skilled in the art that other resilient biasing means can be used, such as a gas spring, a leaf spring or a torsion spring. Braking means (not shown) such as frictional braking means are also provided and the brake can act directly or indirectly on the elongated member 6.
The combination of the resilient biasing means and the braking means ensures that the sash 3 can assume and maintain any open position and will not change such an assumed open position due to the influence of gravity, wind or any other forces that can be expected to act on the sash 3 during normal use. However, the combination of the resilient biasing means and the braking means is such that an operator applying manual force to the sash 3 will be able to move the sash with relative ease.
The sash 3 can in this embodiment also pivot about a hinge 9 at the free end of arms 8 so that the sash 3 can be reversed, e.g. for cleaning the outer side of window pane 11 from the inner side of the roof window 1.
The frame 2 is provided with an opening that matches the sash 3 and in this embodiment the frame 2 is provided with a seal or gasket 30 that surrounds the opening and provides for a tight seal with the sash 3 when the sash is in a fully closed position. The seal or gasket 30 can be made of compressible material or can be made of flexible material that is arranged to fold or bend when it is compressed. Typically, the seal or gasket 30 is made from an elastomeric material.
When the sash 3 is in a nearly closed position, the sash 3 is proximate to the frame 2. In this position the opening in the frame 2 is almost closed, and the seal or gasket 30 is not, or only to a minor extent, compressed (e.g. only compressed in the area of the gasket closest to the hinge 4). Fig. 6 illustrates the nearly closed position of the sash 3. The compressible seal 30 is at least partially compressed in most of its extend around the opening when the sash 3 is in the fully closed position.
The controller 50 is in an embodiment provided with a user interface or connected to a device with a user interface such as a remote control unit which could e.g. be a smartphone with an app installed thereon for partially controlling the operation of the roof window 1 via the controller 50. Via the user interface the controller 50 can receive instructions from an operator to move the sash 3 from a near closed position to a fully closed position, or to lock or unlock the sash to the frame. The controller 50 may also be connected to other sensors, such as a rain, storm or squeeze protection sensor and the controller 50 may be configured to automatically lock the window when rain or storm is detected and the controller may be configured to withdraw the last movement of the sash when the squeeze sensor signals a squeeze event. The controller 50 may also receive other external signals that do not come directly from an operator for locking the sash 3.
The controller 50 is also connected to a first sensor 32 that detects when the sash 3 is in a nearly closed position where it is proximate to the frame 2, and in an embodiment the first sensor 32 can detect whether the sash 3 arrives at the nearly closed position from an open position.
The roof window 1 is provided with a motorized electronically operated lock 20 that comprises a first cooperating lock part 22 arranged in or near the bottom end of the frame 2 and second cooperating lock part 24 arranged in or near the bottom end of the sash 3. The first cooperating lock part 22 and the second cooperating lock part 24 can engage and disengage one another, i.e. the first cooperating lock part 22 and second cooperating lock part 24 are configured to engage one another when the sash 3 arrives from an open position at the nearly closed position. In an embodiment the first sensor 32 is configured to detect that the first cooperating lock part 22 and the second cooperating lock part 24 have engaged.
The second cooperating lock part 24 is operably connected to a handle 18 so that it can also be operated manually. The handle 18 also allows for manual operation of the sash 3 in order to move it between closed, nearly closed and open positions. The first cooperating lock part 22 is connected to the controller 50. The first cooperating lock part 22 is configured carry out a motorized movement that pulls the sash 3 from the nearly closed position to the fully closed position when, i.e. as a soon as, the first and second cooperating lock parts 22,24 engage one another. Hereto, the controller 50 receives a signal from the first sensor 32 that indicates to the controller 50 that the sash 3 has arrived at the nearly closed position from an open position. In an embodiment the signal from the first sensor 32 can also indicate to the controller 50 that the first and second cooperating lock parts 22, 24 have engaged one another. Upon receipt of the signal from the sensor 32 the controller 50 issues a signal to the first cooperating lock part 22 to carry out the motorized movement that pulls the sash 3 from the nearly closed position to the fully closed position.
Thus, the first sensor or switch 32 is configured to cause a first signal to be transmitted to the motorized electronically operated lock to pull the sash 3 from the nearly closed position to the fully closed position when the sash 3 reaches the nearly closed position from one of the open positions.
The first sensor or switch 32 may in an embodiment also be configured to cause a first signal to be transmitted to the motorized electronically operated lock 20 to pull the sash 3 from the nearly closed position to the fully closed position when the first and second lock part 22,24 engage one another.
The motorized electronically operated lock is preferably configured to lock or latch the sash 3 after or when drawing the sash 3 to the closed position. A signal hereto can be issued under command from the controller 50.
In an embodiment the motorized electronically operated lock 20 is configured to actively move the sash 3 from the fully closed position to the nearly closed position and to release the sash 3 by disengaging the first and second lock parts 22,24 upon receipt of a control signal from the controller 50.
In another embodiment the motorized electronically operated lock 20 is configured to allow the sash 3 to move from the fully closed position to the nearly closed position and to release the sash 3 by disengaging the first and second lock parts 22,24 upon receipt of a control signal form the controller 50.
The controller 50 is in an embodiment configured to send a control signal to the motorized electronically operated lock 20 to pull the sash 3 from the nearly closed position to the fully closed position when the controller 50 receives a signal from the first sensor 32 indicating that the sash has reached the nearly closed position from one of the open positions.
The first cooperating lock part 22 is configured to provide a pulling force for pulling the sash 3 from the nearly closed position to the fully closed position that is sufficiently large to compress the compressible seal 30. Hereto, the first cooperating lock part 22 can be provided with an electric motor that provides the required force, such as e.g. a linear electric drive motor or a rotating electric motor connected to means that convert rotational movement of the drive motor to a linear movement, such as e.g. spindle or a chain or a rack.
Fig. 8 shows an embodiment of the motorized electronically operated lock 20 in greater detail. The first cooperating lock part 22 is connected to the frame 2, preferably integrated therein, and comprises in an embodiment a moveable part 26 that is operated by a motor or actuator 27, preferably under command from the controller 50, to move between a first position and a second position as indicated by the vertically directed double arrow in Fig. 8. The movable part 26 is provided with an engagement member 23 in the form of an L-shaped slot that opens towards an edge of the movable part 26 and the slot 23 is configured to receive and engage second engagement member 25 of the second cooperating lock part 24. In the first position a first engagement member 23 of the first cooperating lock part 22 is placed in a position to engage the second engagement member 25 of the second cooperating lock part 24 when the sash 3 is in the nearly closed position, and the second position (shown in Fig. 8) places the first cooperating lock part 22 in a position where the sash 3 is fully locked when the second engagement member 25 is engaged with the first engagement member 23.
The second cooperative lock part 24 is connected to the sash 3 and preferably integrated therein and comprises a movable member 60 that is provided with second engagement members 25. In the present embodiment the movable member is a bar 60 that is configured to slide in the sash 3 in the direction of the horizontal double arrow in Fig. 8 and the engagement members 25 are pegs 25 that protrude from the bar 60 and the pegs 25 are configured for engaging the slot 23 in the first cooperative lock part 22. The bar 60 is also provided with an array of rectangular shaped recesses or openings 62 that are configured for engaging the teeth 19 of a rotatable sprocket that is attached to the rotatable handle 18. Thus, rotation of the handle 18 by an operator will cause rotation of the sprocket and thereby a translational movement of the bar 60 and the pegs 25 as indicated by the horizontal double arrow in Fig. 8 for manual operation of the motorized lock 20.
The bar 60 is also provided with a peg 63 that is configured to engage a bracket 70. The bracket 70 is operably connected to an actuator or motor 72 that can move the bracket 70 sideways as indicted by the double arrow in the bracket to render the latter into a motorized engagement member configured to move the second cooperating lock part 24 between an engaged position (is not shown in Fig. 8) and a disengaged position (shown in Fig. 8), preferably in response to a signal from the controller 50.
According an embodiment the first engagement member 23 of the first cooperating lock part 22 and the second engagement member 25 of the second cooperating lock part 24 are configured to activate engagement automatically when the sash 3 arrives at the nearly closed position from one of the open positions.
Hereto, the controller 50 is in the embodiment of Fig. 8 configured to activate motor or actuator 72 when the sash 3 is in the nearly closed position with the pegs 25 received in the L-shaped slot 23, to be precise with the pegs 25 at the bottom of the horizontally extending leg of the L-shaped slot 23, as indicted by the pegs 25 drawn with interrupted lines. In this position of the sash 3 the peg 63 is received inside the bracket 70 as indicated by the dotted version of the peg 63 in Fig. 8. Activation of the motor or actuator 72 will cause the bracket 70 to move to the left (left as in Fig. 8) and thereby push the peg 63 and thereby the bar 60 with the pegs 25 leftwards, which in turn causes the pegs 25 to move leftwards into the dead end of the horizontal leg of the L-shaped slot 23, as also indicated by the pegs 25 drawn with interrupted lines in Fig. 8. Thus, the first cooperating lock part 22 has engaged the second cooperative lock part 24. Next, the controller 50 activates motor 27 and pulls the movable parts 26 with the pegs 25 caught in the L-shaped slot 23 downwards (downwards as in Fig. 8), thereby also pulling the second cooperative lock part 24 and therewith the sash 3 towards the frame 2 to the fully locked position of the sash 3.
When the sash 3 is to be opened the procedure is reversed, and the controller 50 starts by activating the motor or actuator 27 to move in the upward direction (upward as in Fig. 8) until the sash 3 assumes the nearly closed position. The controller 50 may in an embodiment receive a signal from the sensor 32 that the nearly closed position has been reached, and in an embodiment the sensor will also detect that the sash came to the nearly closed position from the fully closed position.
Next the controller 50 will activate the motor or actuator 72 so that the latter will move to the right (right as in Fig. 8) and thereby also move the peg 63 and the bar 60 including the pegs 25 to the right. Thereby the pegs 25 arrive again at the bottom of the upwardly extending leg of the L-shaped slot 23 and the first cooperating lock part 22 and the second corporate and lock part 24 are thereby disengaged. Next, the sash 3 can be moved to open positions manually or by a sash actuator 40.
According to another embodiment the motorized electronically operated lock 20 is operatively connected to a handle 18 for manual locking and unlocking of the sash 3.
Hereto, it is noted that the top hung or pivot hung roof window is not provided with a sash actuator, i.e. all opening and closing movement between the nearly closed position and the open positions is manual. An actuator could be retrofitted onto said roof window if so desired in the future. In such a case, the actuator will be configured to automatically disengage the sash 3 when the sash 3 is manually moved.
According to another embodiment the first engagement member 23 of the first cooperating lock part 22 i.e. the slot 23 may be provided by an electromagnet activated striker plate which releases the second engagement member 25 of the second cooperating lock part 24 based on a signal from the controller 50.
Fig. 9 shows the motorized electronically operated lock 20 according to another example embodiment that is slightly different from the embodiment shown in Fig. 8, in that the first lock part 22 operates with a single motor 72 for the engagement procedure and for pulling of the sash 3 to the locked position. The second lock part 24 is essentially identical to Fig. 8. The first lock part is provided with two slanting slots 23 that can both engage the pegs 25 and draw the pegs 25 towards the frame 2 and thereby pull the sash 3 to its completely closed and locked position. The single motor or actuator 72 is operably connected the bracket 70 that is configured to engage the peg 63. When the controller 50 receives a signal from the first sensor 32 that the sash 3 is in the nearly closed position, it commands the motor or actuator 72 to move towards the right, thereby forcing the pegs 25 towards the bottom or dead end of the sloping slot 23. This action will cause the pegs 25 to be retained in the sloping slot 23 and this action will cause the pegs 25 to be drawn towards the frame 2 and thereby the sash 3 is urged to the closed position. 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. 9) and push the peg 63 and thereby the pegs 25 towards the free opening of the sloping slot 23. Thereby, the pegs 25 in the second cooperating lock part 24 are engaged from the first cooperating lock part 22 and thus the sash 3 is no longer locked.
Fig. 3 is diagrammatic side view of an example embodiment of the top or pivot hung roof window 1. In this embodiment 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. 4 is a diagrammatic side view of an example embodiment of the top or pivot hung roof window 1. In this embodiment 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. 4 for manually disengaging the latch 25. The operation of the roof window 1 according to this embodiment is illustrated in Figs. 6 and 7.
Fig. 5 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. 8.
Fig. 6 shows the roof window of Fig. 4 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. 7.
One advantage of the disclosed motorized lock is that a high closing force of 10-50 Kg is applied only at the end of the closing movement, thereby reducing the risk of getting body parts stuck between the frame and sash, and preventing large force exposure to any such 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.
Although the present invention has been described in detail for purpose of illustration, it is understood that such detail is solely for that purpose, and variations and combinations can be made therein by those skilled in the art without departing from the scope of the appended claims. For example, the embodiments have been described with reference to a single controller, and with a single sensor for detecting the position of the sash. However, as will be apparent by those skilled in the art, there is more than one controller could be used to control the motorized lock and separate sensors could be provided for detecting the position of the sash and for detecting the position of the motorized lock and for detecting the state of the motorized lock, i.e. the lock being engaged or not engaged.
The term "comprising" as used in the claims does not exclude other elements or steps. The term "a" or "an" as used in the claims does not exclude a plurality.
