Description

The invention relates to a window comprising a Frame with an upper part, a lower part and two side parts that together form a frame level result, as well as one at an axis of rotation of the window Hinged wing frame with the frame with an upper part, a lower part and two side parts, which together define a sash level, and where the casement by means of an actuator from a closed position, in which is essentially the plane of the casement runs parallel to the plane of the frame, in an open position in which the sash level forms an angle with the frame level, moves can be, wherein the window further on the top and / or lower part of the casement rotatably mounted Element includes which element between a first Position, where with the help of locking organs, which in the Upper and / or lower part of the frame provided Intervention means engage the sash on the Frame is held, and a second Position in which the casement is from the frame is cleared, as can be rotated by actuation Elements of the engagement between the closing elements and the engagement elements is released can be, and where mentioned actuator with the frame on its lower part rotatably connected Receiving element and one opposite the receiving element includes sliding actuating arm, its outer end with the rotatable element in Connection is established.

Unlockable windows and corresponding flaps, among others are used for smoke ventilation, just like the associated opening mechanisms, in many different designs known.

In its simplest form, the window is or the flap hung up, i.e. the casement is with the frame on the relevant tops hinged, and the actuator is placed at the relevant lower parts. This Placement of the actuator, the rest also for bottom hung windows, whose hinge axis essentially coincides with a central axis of the window, can now be used great lengths of the receiving element, which in turn entails that the actuating arm accordingly long and thus in the open position of the window becomes unstable.

From, for example, EP Patent Application No. 0 971 091 and DK Patent No. 162 110 are suspended above Constructions known where the casement is opposite the frame using link-divided guide mechanisms which management mechanisms are opened with the receiving element of the actuator in Connect, with the receiving element in each these writings formed as a compressed air cylinder is why cylinders with a shorter stroke length than in previously known constructions can be used can; however, these devices are not suitable for windows and flaps with a central axis are hinged.

An alternative placement of the actuator is shown in EP patent application 0 692 640 and described where the receiving element in the form of a Printing cylinder with the frame on its lower part is rotatably connected, and where as the operating arm active piston rod with the upper part of the casement is rotatably connected. This arrangement entails that even with hinges connected around a central axis Windows or flaps with actuators shorter length can be used.

This placement of the actuator also occurs in a known pressure-controlled smoke ventilation unit for windows of the type mentioned, where a pressure cylinder is mounted on the lower part of the frame, and the outer end of the piston rod of the pressure cylinder with the gripping bar arranged on the ventilation flap, which for actuating the Operating element acting ventilation flap and thus deactivating the closing members relative to the engagement elements is connected. A CO ₂ cartridge, triggered either manually or by a fuse, is used to activate the unit's air cylinder. In the open position of the window, the casement can only be manually returned to the closed position, after which the CO ₂ cartridge and the fuse must be replaced in order to bring the window back into its original position. Apart from the fact that the window is only used for smoke ventilation after the unit has been installed, the unit cannot be changed over immediately to close the window, since activating the actuating device in the opposite direction closes the ventilation flap and thus activates the closing elements before pulling the casement against the window frame, or does not make it possible to close and close the window, in the case where the closing mechanism of the window includes blocking elements which are activated when the ventilation flap is opened and which the ventilation flap only at the stop move against the strike plate on the frame.

In view of this, the invention is the Task based on a window of the introductory Art to improve such that the window is optional for Comfort ventilation can be used, i.e. that it as desired using the actuator can be opened and closed again.

This is achieved by using such a window is marked that the rotatable connection between the receiving element of the actuating device and the frame at a distance from the frame lower part, in relation to the frame level essentially is placed at right angles inside, and that the rotatable connection between the actuating arm and the sash is designed such that the rotating element before opening the window the actuator from the mentioned first position is brought into the second position, and under the opening and subsequent closing of the window in this position remains until the casement against the frame is pulled.

With such a placement of the actuator you achieve an optimal combination of Moments that under opening and closing on the Sash is exercised, and of the ventilation flap acting moments because the size of this Moments ensures that opening and closing the Window is done in a reliable manner, preventing is that the locking organs are activated, before pulling the casement against the frame is, alternatively, that attached to the rotatable element transmitted force does not become so large that a Unlocking the locking organs is impossible. On It is therefore possible to control the smoke opening system be done quickly and efficiently, as well the window beyond the smoke ventilation function can also be used for normal ventilation, and e.g. to an electronic control system for opening and Closing one or more windows connected can be. In addition, this placement leads the Actuator with itself that the closing force can be controlled very precisely, which includes for the Window sealing system is important, as well like the damage that could occur if, for example Fingers or other body parts with the Closing movement of the casement comes into contact, be limited.

In a preferred embodiment of the invention comprises mentioned rotatable element with the Casement upper part running parallel and with this hinged ventilation flap, and the Actuator arm is close to the casement Hinge connection of the ventilation flap with the Casement upper part connected.

In a simple in terms of construction Embodiment is the receiving element with the frame connected via a console that extends from the Lower frame part essentially at right angles extends inside and is connected to it, and the has such a length that in the closed Position of the window between the actuator and the window frame plane formed an angle becomes.

With a view to increased flexibility in the choice of actuators, such an actuator either an electrical spindle actuation be, the receiving element a Spindle control and the actuating arm a spindle comprises, or pressure medium controlled, preferably be pneumatically controlled, the receiving element a cylinder and the actuating arm a piston rod includes.

In an alternative embodiment of the invention Window can be the actuator a link mechanism with a link include one end of which is connected to the operating arm rotatable and slidable, and its other end is rotatably connected to the rotatable member.

With this version it is possible to have a window to instruct with a standard actuator since their receiving element and actuating arm a may have predetermined length while the length of the link depending on the length of the current window can be varied.

In a constructionally advantageous further development this embodiment comprises the connection between the link and the operating arm close to or on a casement side panel at a distance from the upper or lower part of the sash frame mounted fitting and a pin on both Ends in a groove provided in the fitting in the essentially parallel to the sash side part to be led.

Other advantageous embodiments go out the remaining dependent claims.

An actuator 4, which serves the Window from the closed position to an open one Positioning is mounted on the window. The Actuating device 4 comprises an actuating arm 5 and a receiving element 6 for the actuating arm 5, and is electrical in the embodiment shown Spindle actuation, whereby the actuating arm 5 is made of a spindle and the receiving element 6 from one Spindle control exists. As an alternative, one pressure medium controlled, for example pneumatic Actuator with a cylinder and an im Relation to the cylinder movable piston rod in Connection with a working piston used in the cylinder become.

The actuator 4 can either on the Window pre-assembled or with regard to the following Mount separately on an existing window to be delivered. One end of the receiving element i.e. the spindle control 6, is at 7 with one End of a console 8 rotatably connected, which console at the opposite end to the bottom part 1c of the Frame is attached. The console 8 has one such length that in the closed position of the window between the actuator and a plane formed by the frame an angle is shown in Fig. 2 with a dash-dotted line is. The outer end of the spindle 5 is over a fitting 9 with a rotatable element in which Embodiment shown an on the upper part of the casement provided ventilation flap 10, but can also another rotatable that is known per se Activation or control element, rotatable connected. The ventilation flap 10 is by means of a Hinge connection 11 with the sash upper part connected and has a gripping bar 12 which for manual operation of the window can be used. The fitting 9 of the spindle 5 is close to the hinge connection 11 between the ventilation flap 10 and the upper part of the sash 3 in such Distance fixed that when activating the operating arm a relatively small moment about this axis is secured in such a way that the ventilation flap 10 around the hinge connection 11 can be tilted from a first position where they are attached to the casement is applied accordingly, that the casement on the frame is held in a second position simultaneous release of the interference between the Closing members and the engaging elements before Opening the window, and accomplishing this Intervention after closing the casement the window is pulled against the window frame, i.e. where the ventilation flap from its second position in the first position is performed. The placement of the Actuator has the consequence that the Closing force controlled very precisely and to a value can be reduced to 150 N, which damages, which could arise if, for example, fingers or other body parts with the closing movement of the Sash come into contact, limited.

When actuating device 4 is activated, which e.g. by means of an electronic control system can take place, the spindle 5 exerts a train in the Ventilation flap 10 from under its rotation around the hinge 11 the closing members of the casement from their engagement with the engaging elements of the The frame triggers, after which the entire sash 3 for Achieve the desired ventilation or smoke ventilation position about the hinge axis 2 of the window turns, such as shown in Fig. 2 where a plane through the sash 3 with a plane through the frame 1 forms an angle. The maximum opening angle of the casement 3 relative to the frame 1 is limited by the length of the spindle control 6, or because the spindle 5 due to the ventilation flap 10 no longer into the spindle control 6 can be moved.

When the window is closed, the operating device 4 to move the spindle into the opposite direction activated, the sash 3 rotates about its hinge axis 2 until the Upper sash frame in contact with the upper frame 1a comes, after which the ventilation flap 10 under the last part of the movement of the spindle around their Hinge connection 11 rotates and thereby the closing members of the casement activated with the engaging elements engaged on the frame become.
