BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a window comprising a frame with a head, a bottom piece and two side pieces which together define a frame plane, and a frame with a frame axis pivotally connected to a frame with a head piece, a bottom piece and two side pieces which together define a frame plane. wherein the frame can be moved by means of a maneuvering device from a closed position in which the frame plane is substantially parallel to the frame plane to an open position, in which the frame plane forms an angle with the frame plane, the window also comprising one at the top of the frame. and / or bottom piece rotatably mounted member movable between a first position, corresponding to the frame being secured to the frame by locking means 15 engaged by engagement members at the top and / or bottom of the frame, and a second position , corresponding to the frame being released from the frame, the engagement between the locking means and the engaging elements can be released by operation of the frame. said rotatable member, and wherein said maneuvering device includes a receiving member pivotally rotatable at its bottom and a maneuverable movable arm relative to the receiving member, the outer end of which communicates with said rotatable member.

25 Open windows and similar hinges, which are used, among other things, for smoke ventilation, are known in many different designs, as are the associated opening mechanisms.

In its simplest form, the window or limb 30 is top hung, ie. the frame is hingedly connected to the frame at their respective headers, and the maneuvering device is located at the respective headers. However, this positioning of the maneuvering device, which can also be used for tilt windows, where the hinge axis substantially coincides with a center axis of the window, gives rise to relatively large lengths of the recording element, which in turn causes the maneuvering arm to become correspondingly long and thus unstable in the open position of the window.

For example, from EP patent application no. 0 971 091 and DK patent no. 162110, top-hung structures are known in which the frame is opened relative to the frame by means of 10 articulated guiding mechanisms which are in connection with the maneuvering element of the device which is carried out in each of these writings. as a compressed air cylinder, whereby cylinders of less stroke can be used than in prior art constructions, but these arrangements are not suitable for use with windows and hinges hinged at a central axis.

An alternative location of the maneuvering device is shown and described in EP Patent Application No. 0 692 640, wherein the receiving element in the form of a compressed air cylinder 20 is pivotally connected to the frame at its bottom piece and where the piston rod acting as a maneuvering arm is pivotally connected to the top of the frame. This arrangement means that 25 maneuvering devices of shorter length can also be used for windows or hinges hinged at a central axis.

This location of the maneuvering device is further found in a known pressure medium controlled smoke ventilation unit for windows of the kind mentioned above, where a compressed air cylinder is mounted at the bottom of the frame, and the outer end of the piston rod cooperating with the compressed air cylinder is connected to the ventilation valve. grab bar used to operate the valve actuating as a control element and thereby deactivate the locking means relative to the engagement elements. To activate the unit's compressed air cylinder, a CO 2 cartridge is used which is triggered either manually or by a fuse. In the 5 open position of the window, the frame can only be manually returned to the closed position, after which the C02 cartridge and fuse protection must be replaced to bring the window back to its initial state. In addition to the fact that, after mounting the unit, only 10 is designed to be used for smoke ventilation, the unit can not immediately be switched to also be able to close the window, since operation of the maneuvering device in the opposite direction will. cause the ventilation flap to close and thereby activate the locking means before the frame is pulled against the frame, or to prevent the closing and locking of the window in the case where the window locking mechanism comprises locking means which are activated by opening the ventilation flap and which first release the ventilation flap 20 to movement by impact towards the final look on the frame.

In view of this, it is an object of the invention to improve a window of the kind mentioned above, so that the window can be used optionally for comfort ventilation, ie. can be opened and closed again after 25 requests, using the maneuvering device itself.

This object is achieved by such a window being characterized in that the pivotal connection between the receiving element of the maneuvering device and the frame is spaced apart from the frame bottom, substantially 30 perpendicular inwards with respect to the frame plane, and that the pivotal connection between the maneuvering arm and the frame is designed so that the rotatable element prior to opening the window of the maneuvering device is moved from said first position to the second position, and remains in this position during opening and subsequent closing of the window until the frame is pulled against the frame.

By positioning the device in this way, an optimal combination of the torque exerted on the frame during opening and closing and the torque acting on the ventilation flap are ensured, the magnitude of these moments ensuring that the opening and closing of the window can occur. reliably, while preventing the locking means from being actuated before the frame is pulled against the frame, or alternatively, the force transmitted to the rotatable member does not become so large as to enable the locking means to be unlocked. The control of the smoke opening system 15 can thereby be carried out quickly and rationally, just as the window, in addition to the smoke ventilation function, can also be used for ordinary ventilation, and thus will e.g. could be connected to an electronic control system for opening and closing one or more windows. In addition, this positioning of the maneuvering device implies that the closing force can be controlled very precisely, which is important for, inter alia, the window sealing system, as well as limiting the damage that could occur if e.g. fingers or other body parts get in the way of the frame's closing movement.

In a preferred embodiment of the invention, said rotatable member comprises a parallel to the frame top piece and with this hinged ventilation flap, and the maneuvering arm is connected to the frame near the hinge connection of the ventilation flap with the frame top piece.

In a design-simple embodiment, the receiving element is connected to the frame by means of a bracket which is connected to and extends substantially perpendicularly inward from the frame bottom and having a such a length that in the closed position of the window an angle is formed between the maneuvering device and the frame plane.

For added flexibility in selecting the maneuvering device, this may be either an electric spindle operator, the receiving member including a spindle guide and the maneuvering arm including a spindle, or the pressure medium controlled, preferably pneumatic, the receiving member including a cylinder and the maneuvering arm including a maneuvering arm.

In an alternative embodiment of the window according to the invention, the maneuvering device may further comprise a linkage mechanism with a link link rotatably and slidably connected to the maneuvering arm with one end and rotatably connected to the rotatable member.

With this embodiment, it will be possible to provide a window with a standardized maneuvering device, its receiving element and maneuvering arm may have a predetermined length, while the length of the link joint may be varied depending on the length of the current window.

In a constructionally advantageous further development of this embodiment, the connection between the link joint and the maneuvering arm comprises a bracket mounted on or near a frame side piece at a distance from the frame top or bottom piece, and a pin at each end guided 30 in a groove in the bracket. substantially parallel to the frame side piece.

Other advantageous embodiments are apparent from the remaining dependent claims.

The invention further relates to a maneuvering device comprising a receiving element having a maneuverable arm relative to this axially, the maneuvering device comprising a bracket in connection with the receiving element and a bracket in connection with the outer end of the maneuvering arm, the bracket being adapted to be connected to the frame bottom for the window, and the bracket with the rotatable element of the window.

For use in a window of the above-described alternative embodiment, the device comprising a receiving member having a relative to this axially displaceable operating arm may further comprise a bracket in connection with the receiving member and a bracket in connection with the outer end of the the maneuvering arm, the bracket being arranged to be connected to the frame bottom of the window and the bracket with a link joint for connection with the rotatable element of the window.

The invention will be explained in more detail below with reference to an example of an embodiment and with reference to the schematic drawing, in which fig. 1 is a sectional view through a window according to a first embodiment of the invention, in the closed position; FIG. 2 is a view of the embodiment of FIG. 1, but where the window is partially open, FIG. 3 is a sectional view through a window according to another embodiment of the invention, in the closed position; FIG. 4 is a view of the embodiment of FIG. 3 in the closed but released position, and FIG. 5 is a view of the embodiment of FIG. 3 in partially open position.

The FIG. 1 and 2 include a generally 7 DK 176087 B1! 1 is designated a frame structure associated with the roof structure of a roof surface which may not be inclined, as indicated in the drawing, or plane. Alternatively, the window can also be used in a facade. At a 5 axis of rotation 2 of the window, which in the illustrated embodiment is a center axis, the frame 1 is not hingedly connected with a frame 3 at the lateral sections of the roof slope which are normally extending in the direction of the roof slope. the frame 1 and the frame 3, from which can be seen in the figures one side portion 1b of the frame 10 and one frame piece 3d.

In addition, the frame 1 comprises a top piece 1a, a bottom piece 1c and a second side piece (not shown). Similarly, the frame 3 also includes a head piece, a bottom piece and a second side piece, and the frame pieces 15 include in a manner known per se, e.g. an insulation pane (not shown).

In the embodiment shown in FIG. 1 in the closed position of the window, non-shown locking means engage at the top of the frame 3 with also not shown engagement elements formed at or in the top of the frame 1a, thereby holding the frame 3 with respect to the frame 1. A maneuvering device 4 arranged to bring the window from the closed position to an open position mounted on the window. The maneuvering device 4 comprises a maneuvering arm 5 25 and a receiving element 6 for the maneuvering arm 5, and in the illustrated embodiment is an electric spindle operator, the maneuvering arm 5 being a spindle and the receiving element 6 being a spindle guide. Alternatively, a pressure medium controlled, e.g. pneumatic, maneuvering device may be used with a cylinder and a relative piston rod relative to this displaceable piston in connection with a working piston in the cylinder.

8 DK 176087 B1

Maneuvering device 4 can either be pre-mounted on the window or supplied separately for retrofitting to an existing window. One end of the recording element, i.e. of the spindle guide 6, at 7 5 is pivotally connected to one end of a bracket 8 which is fixed at the opposite end to the bottom piece 1c of the frame. The bracket 8 is designed with such a length that in the closed position of the window an angle is formed between the maneuvering device and a plane through the frame, indicated by a dotted line in FIG. 2. The outer end of the spindle 5 is pivotally connected to a pivot 9 by a pivot member which, in the embodiment shown, is a ventilation flap 10 at the head of the frame 3, but which could also comprise any other pivotable actuating actuator 15 known in the art. or controls. The ventilation flap 10 is connected to the frame top piece by a hinge connection 11 and has a gripping strip 12 which can be used for manual operation of the window. The bracket 5 of the spindle 5 is secured close to the hinge connection 11 between the vent flap 10 and the head piece of the frame 3 at such a distance that a relatively small torque about this axis is secured by actuation of the maneuvering arm so that the vent flap 10 can be tilted about its hinge lining. -25 connection 11 from a first position where it abuts against the frame and corresponding to the frame being held to the frame, to a second position during simultaneous release of the engagement between the locking means and the engagement element prior to opening the window, and to providing this engagement after the frame is pulled against the frame during closing of the window, i. where the ventilation flap is passed from its second to its first position. The location of the maneuvering device means that the closing force can be controlled very accurately and can be reduced to a value as low as 150 N, which limits the damage that could occur if e.g. fingers or other body parts get in the way of the closing motion of the frame 5.

By activating the maneuvering device 4, which e.g. can be effected by means of an electronic control system, the spindle 5 exerts a pull in the vent 10 which, during its rotation about the hinge 11, releases the locking means of the frame 10 from their engagement with the engagement elements of the frame, after which the entire frame 3 is rotated about the hinge axis 2 of the window to obtain the desired vent or smoke ventilation position, e.g. as shown in FIG. 2, where a plane through the frame 3 forms an angle with a plane through the frame 1. The maximum opening angle of the frame 3 with respect to the frame 1 is defined by the length of the spindle guide 6, or by the fact that the spindle 5 cannot be moved further into the spindle guide 6 on due to the vent 10.

Upon closing the window, the actuator 4 for movement of the spindle is actuated in the opposite direction, whereby the frame 3 rotates its hinge axis 2 until the frame top piece abuts against the casing top 1a, after which the ventilation flap 10 during the last part of the spindle 5's movement pivots about its hinge. 11, thereby activating the locking means of the frame 3, which are engaged with the engagement elements of the frame.

In order to increase the safety that the vent flap 10 is first tilted about the hinge connection 11 when the frame is pulled against the frame, the locking means may in a known manner be provided with locking means which are activated upon opening the vent flap and which releases the ventilation flap 10 DK 176087 B1 for movement by impact against the final look or the like on the frame.

In FIG. 3-5 show an alternative embodiment of the window according to the invention, in which elements having the same or analogous function as in the embodiment of FIG. 1-2 bear the same reference numerals with 100 placed above.

In this embodiment, the maneuvering device 104 further comprises a generally designated linkage mechanism 120 with a link joint 121, which is rotatably and slidably connected at one end to the maneuvering arm 105. In the embodiment shown, the connection comprises a U-shaped bracket 122 mounted on the associated frame side piece. at a distance from the frame top piece. The outer end of the maneuvering arm 105 and the end of the maneuvering device 104 15 facing the linker 121 are mounted on a pin 123 which is guided in a groove 124 in the two opposite walls of the bracket 122. The grooves 124 extend substantially parallel to the frame side pieces.

By opening the window in this embodiment 20, the maneuvering device 104 is activated in a similar manner as described above, whereby the spindle 105 exerts a throttle in the pin 123 and thereby in the latch joint 121.

This causes the pin 123 to move in the groove 124 while simultaneously moving the vent flap 110 to the one shown in FIG. 4. Subsequently, the entire frame 103 can be rotated about the window hinge axis 102 to obtain the desired vent or smoke ventilation position, e.g. as shown in FIG. 5th

Upon closing the window, the maneuvering device 104 for moving the spindle in the opposite direction is activated, whereby the frame 103 rotates its hinge axis 102 until the frame top piece abuts against the frame top piece. During this movement, the ventilation flap is held in its open position by means of locking means as described above. After the locking means have released the ventilation flap for movement upon impact against the frame end, the ventilation flap 110 during the last part of the movement of the spindle 105 can rotate its hinge connection 111, thereby activating the locking members of the frame 103 which engage the engagement elements of the frame.

The invention is not limited to the embodiments shown and described above, but can be varied within the scope of the following claims. Thus, the exact location and design of the parts of the actuator relative to the window can be varied as long as it is ensured that a proper function is maintained.

Thus, it goes without saying that maneuvering the uptake element of the device with appropriate modifications can be placed at the top of the frame as well as outside the window, and the terms top, bottom and side in connection with the elements of the frame and frame are of course arbitrary. The rotatable member may also be located at the base. The invention is also applicable to windows with positions of the axis of rotation other than the center axis shown, the window thus being top, bottom or side hung.
