Description

The invention relates to a roof window, in particular Swing-wing skylight, with a frame and a wing frame that is articulated to subframe profiles arranged by one Swing axis is pivotally mounted, wherein the oscillation axis is horizontal and approximately in the middle Area located on the casement, and with a preloaded spring device.

From German utility model 74 16 262 it is known a spring device for a swing-wing roof window to provide that with one end is pivotally attached to the frame and their attacks the other end on subframe profiles that on the one hand swiveling on the frame and on the other hand pivotally mounted on the casement are. The spring device exercises when unlocking of the window a positioning force on the respective Subframe profile, so this is about the Pivot axis on the frame is pivoted and in this way, the placement of the casement supported in a swing opening position.

There are windows under the swing-wing skylight understand whose frame is built into the roof skin are and their window sash by about in the center of the window sash swingable are. Such swing wing skylights have the advantage of being able to clean the outside the glazing pivoted so far about the swing axis can be that the outer glass surface from Interior can be cleaned. The Swing axis therefore not only offers the possibility the ventilation position, but also one easy exterior glass cleaning.

Furthermore, roof windows, especially residential roof windows, known, which is designed as a hinged window are, that is, the window sash is in the area of the upper frame cross section pivoted. While with a swing window as a result of arrangement of the swing axis close to the center of gravity Opening no significant torque applied must be, is with a hinged window due to the torque generated by the weight of the window sash a correspondingly large force for a window opening to apply. To avoid this have the different hinged window designs spring devices or the like that generated that Essentially intercept torque. There are also hinged swing window known, both a Folding movement as well as a swinging movement of the Allow sash. The present invention deals with swing windows or else also with hinged swing windows, that is, the casement is about in its central area lying swing axis movably mounted.

To be a special one with a swing-wing roof window Achieve inexpensive construction it is possible to brake the wing with simply braked Equip pivot bearings in the middle the side rails of the casement lie so that the window sash is balanced in weight. However, they are in a different design Pivot bearing still in the middle, however not exactly in the middle of the side rails of the window sash, so you can with the window open realize better headroom, however is now due to the weight distribution Spring device required that the opening movement supports so that the torque is intercepted in the direction of the closed position works. For this support is out of the German utility model 75 14 306 known, on To arrange frame spring-loaded swivel arms, which have roles at their free ends, which are supported on the sash frame and on this Way to support the oscillation process.

The invention has for its object a roof window to indicate the one compared to the previous Different types of construction.

According to the invention, this object is achieved by that the spring device is designed as a vibration aid and has at least one end on the casement (second end) pivotable spring element has its other (first) end as free end interacting with the frame is trained. The spring device according to the invention forms an oscillation aid, that is, it supports it the swinging process of the casement the swing axis that runs horizontally and itself is located approximately in the central area of the casement. "Central area" means in the course of this registration, that the swing axis is not at the top respectively lower cross member is arranged, but in a central zone, including off-center ones Layers are of course included. Because of the function as a vibration aid is opposite the subject of the German utility model mentioned 74 16 262 a completely different construction, because the known device the oscillation process the sash not supported, but the there provided spring device the subframe exhibits.

According to a development of the invention, that the spring element as substantially axial acting spring element, in particular telescopic spring element, is trained. The axially acting design enables simple construction and requires takes up little space. Under a all constructions are axially acting spring elements to understand the axial compression develop a counterforce. That's the way it is for example possible, a kind of cylinder-piston unit to use, the piston by means of a Helical compression spring is acted on. Further can also be used as a spring element Get involved.

According to a further embodiment of the invention it is provided that the free end with a receptacle, especially with a socket, on Frame cooperates, whereby in a first, by swiveling around the second end Pivotal position of the spring element within a certain swing angle range of the casement a support of the free end (first end) the picture is taken and when the Oscillation angle the free end lifts from the receptacle. The spring element is therefore in the area of secondly pivotally held on the casement and in the area of the other, first end within a certain swing angle range - starting with the closed position of the casement - in contact with the receptacle, which is preferred forms a kind of socket. Will the casement moved beyond the certain swing angle, so lifts the first free end off the socket, so that there is no interference with the oscillation process can arise.

In particular, it can be provided that in a certain Pivotal position of the spring element, preferably within the specified swivel range, the free end is next to the receptacle, so that no support is given. By taking this particular The spring element is supported in the pivoting position thus not from the recording, so that the spring element its fully extended end position occupies and also no force on the casement exercises. This has a high security value roof windows not yet installed. For example roof windows unloaded at the construction site - according to the German utility model 75 14 306 the danger that, for example, with a its outside leaning against a wall when moving the operating handle to the open position the frame of the opening Person jumps up, causing injury can lead; and further the window from the Brought balance. This unwanted jump up can only be achieved through elaborate additional facilities, like safety bolts or lever mechanisms, be prevented. In the roof window according to the invention this danger does not occur if the factory pre-assembly the swivel position of the respective Is taken spring element in which the free end is next to the recording, since then there is none Force acts between the frame and sash. Will the window according to the invention in this position built in, a single opening is enough, so that the free end of the telescopic spring element through the weight comes to its "normal" position, being the next time you close the window the free end enters the socket and in this way almost an automatic one Hook in the spring element with a single wide The window is opened.

It is preferably provided that the pivot angle of the spring element is limited by stops. This has the advantage that with an opening movement the sash is not an unattractive and possibly spring element impairing the view protrudes from the casement, but that the spring element about diagonally across the cross-sectional area of the casement extends. This way and Pre-registration is also guaranteed in this way that when closing the casement a safe The free end enters the socket.

Further advantageous embodiments of the invention are marked in the subclaims.

In the course of this registration, usually only one Spring element spoken. However, are preferred two spring elements are provided on a roof window, each longitudinal spar of the casement is such Has spring element. Because the construction of the two spring elements, however, to the longitudinal central axis the casement is identical, should - for the sake of simplicity - only one spring element to be discribed.

1 shows a roof window 1 in side view, that is in the open swing position located. The roof window is a hinged-sash roof window educated. It has one Frame 2 and a sash 3. The one for intended installation in a roof skin, not shown Frame 2 has two parallel to each other spaced longitudinal spars 4 and two also parallel spaced apart Cross bars 5. The sash frame is corresponding 3 with two parallel spaced apart extending longitudinal spars 6 and two parallel spaced mutually extending cross bars 7 equipped. By means of an operating handle 8, the arranged on the lower cross member 7 of the casement 3 is, the roof window 1 can be operated manually. The upper, approximately half sections 9 of the two longitudinal bars 6 of the casement 3 are subframe profiles 10 assigned to the frame 2 in the area of the upper cross member 5 by a horizontal one Axis 11 and on the sash 3 around a horizontal Axis 12 are pivotally mounted.

If the sash 3 is in the closed position, so the subframe profiles 10 are parallel on the longitudinal spars 6 and are in this position fixed. If the operating handle 8 in the folding position pivoted, so the subframe profiles remain 10 coupled in parallel with the longitudinal spars 6, and it's a pivoting of the casement 3 possible about the axis 11 in the folding position. Becomes the operating handle 8 is shifted to the oscillating position and the roof window 1 opened, so that in the Figure 1 taken position. In this there is a decoupling of the subframe profiles 10 of the longitudinal spars 6 of the casement 3 before, so that these about the axis 12 in angular position to each other can reach, the subframe profiles 10 around the axis 11 an angle α to the frame 2 take and the sash 3 about the axis 12th pivoted relative to the subframe profiles 10 can be. The axis 12 forms an oscillation axis, which allows a maximum of about 180 ° rotation of the Make sash 3 around the axis 12, whereby the outside of the casement 3 the frame 2 is turned so that, for example, the Outside of the glazing cleaned from the room can be. To guide the swinging movement of the Sash frame 3 on frame 2 are guide pins 13 provided on the longitudinal spars 6 of the Casement 3 are arranged and in longitudinal guides 14 on the longitudinal bars 4 of the frame 2 intervention.

On each longitudinal spar 6 of the sash 3 is a spring device pivotable about an axis 15 16 arranged, each as a rocking aid 17 is formed. Preferably, the spring device 16 as an axially acting spring element, namely designed as a telescopic spring element 18, so that the effort against a restoring force exists to take a maximum length if possible. The telescopic spring element 18 has a housing 19 on, in which there is a helical compression spring, not shown located. From the housing 19 goes axially fixed support rod 20, the one free end 21 having a first end 22 of the Forms spring device 16. On that of the support rod 20 opposite end of the housing 19 occurs a movable piston rod 23, which by means of the helical compression spring, not shown, axially is biased in the exit position. At the end of Piston rod 23 is a piston rod head 24, which has a second end 32 of the spring device 16 forms, the piston rod head 24 by means of Axis 15 can be pivoted on the associated longitudinal spar 6 of the sash 3 is mounted. The piston rod 23 can be axially inserted into the housing 19 rebound. The free end 21 is preferably spherical thickened. It works Pivot position according to Figure 1- with a support 25 together, the associated longitudinal beam 4 of the Frame 2 is arranged and preferably one Joint socket 26 into which the free end 21st intervenes.

It can be seen from FIG. 3 that the piston rod head 24 has a stop 27 which acts as a stop surface 28 is formed, which with a Stop 29 interacts, the associated Longitudinal beam 6 of the sash 3 is attached and has a stop surface 30. Through the plant the stop surfaces 28 and 30 is ensured - according to FIG. 3 - that the spring device 16 by the gravitational force only within a certain one Swivel the swivel angle range around the axis 15 can, such that the longitudinal axis of the spring device 16 to the longitudinal axis of the longitudinal spar 6 of the casement 3 maximally an acute angle β (Figure 3) can take. That way prevents that when the window is open according to Figure 1, the spring device 16 is a visual impairment represents.

The sectional view in Figure 4 shows the spring device 16 - the housing 19 is not shown here, which with its on the piston rod 23 as Stop surface 28 trained stop 27 with the Stop surface 30 of the stop 29 in a manner interacts that, as described for Figure 3, a pivoting of the spring device 16 only possible in a limited swivel angle range is. This will obscure the view Avoid spring device 16 with the window open. The pivotability of the spring device 16 serving axis 15 also serves for simplicity for the sake of fastening the stop 29 to the longitudinal spar 6 of the sash 3. It is essential that the Construction of stop 29 and / or attachment is designed so that there is a restricted Swivel angle range of the spring device 16 results.

Es sei angenommen, daß sich das Dachfenster 1 in geschlossener Stellung befindet. In dieser Stellung ist das Federelement 16 axial zusammengeschoben, das heißt, es befindet sich in vorgespannter Stellung, in der sich das freie Ende 21 an der Abstützung 25 abstützt. Wird der Betätigungsgriff 8 von einer Bedienperson in Schwingposition bewegt, so nimmt das Dachfenster 1 beispielsweise die Position gemäß Figur 1 ein, das heißt, durch die Rückstellkraft der Federvorrichtung 16 werden einerseits die Hilfsrahmenprofile 10 in der mit α gekennzeichneten Winkelstellung gemäß Figur 1 gehalten, und ferner wird die Position des Flügelrahmens 3 um die Achse 12 stabilisiert. In der in der Figur 1 gezeigten Position ist die Federvorrichtung 16 maximal ausgefahren. Wird nun -von Hand- der Flügelrahmen 3 weiterverschwenkt, so hebt das freie Ende 21 von der Abstützung 25 ab, wie dies in der Figur 2 gezeigt ist. Die Anlage von Anschlagfläche 28 des Kolbenstangenkopfes 24 an der Anlagefläche 30 des Anschlags 29 verhindert, daß in der Position gemäß Figur 2 ein Senkrechtstellen der Federvorrichtung 16 eintritt. Wird das Dachfenster 1 wieder geschlossen, so gelangt das freie Ende 21 aufgrund der erwähnten Anschlagposition automatisch in die Abstützung 25, so daß unter Spannen der Federvorrichtung 16 das Dachfenster 1 geschlossen werden kann.

The following function results:

It is assumed that the roof window 1 is in the closed position. In this position, the spring element 16 is axially pushed together, that is, it is in the pretensioned position in which the free end 21 is supported on the support 25. If the operating handle 8 is moved into an oscillating position by an operator, the roof window 1 assumes, for example, the position according to FIG. 1, that is to say that the restoring force of the spring device 16 on the one hand holds the auxiliary frame profiles 10 in the angular position identified by α according to FIG. 1, and furthermore, the position of the casement 3 about the axis 12 is stabilized. In the position shown in FIG. 1, the spring device 16 is extended to the maximum. If the sash frame 3 is now pivoted further by hand, the free end 21 lifts off the support 25, as shown in FIG. The abutment surface 28 of the piston rod head 24 against the abutment surface 30 of the stop 29 prevents the spring device 16 from being vertical in the position according to FIG. 2. If the roof window 1 is closed again, the free end 21 automatically reaches the support 25 due to the abovementioned stop position, so that the roof window 1 can be closed by tensioning the spring device 16.

Figure 5 illustrates a pre-assembly position the spring device 16. In this pre-assembly position the free end 21 does not point in the direction the upper cross member 5 of the frame 2, but towards the lower cross beam 5. This is achieved by means of appropriate training (not shown) of the stop 29- the stop surface 30 is shifted such that it rotates of the piston rod head 24 is not an obstacle stands in the way. This allows a Swivel movement (arrow 31 counterclockwise or arrow 33 clockwise in Figure 5) of the spring device 16 realize so that the free End 21 does not cooperate with the support 25. In this way there is thus the closed Condition of the roof window 1 no spring preload between frame 2 and sash 3, so that -in the unassembled state of the roof window 1- there is no danger if accidentally the operating handle 8 is pivoted. After another embodiment, not shown it is also possible that the one in FIG indicated pivoting movement (arrow 31) of the spring device 16 to reach the factory Pre-assembly position is carried out, but that the free end 21 towards the upper cross member 5 points, but not in the socket 26 the support 25 engages, but on the Support extends 25. The spring device 16 has its maximum length in this position, being between frame 2 and sash 3rd no forces act and therefore also a safe one Pre-assembly position is reached.

As in detail the construction of the stop 29 must be designed to the position shown in FIG To reach 5 of the spring device 16 remains Left to the specialist, the only thing that matters is that - after installing the window - the stop 29 by moving and defining the stop surface 30 is positioned so that only the restricted Swing angle range of the spring device 16 can be taken.
