Description

The invention relates to a roof window, in particular a swing-wing roof window, with a Frame and a sash, hinged by means of arranged on him subframe profiles a swing axle is pivotally mounted, wherein the swing axis is horizontal and approximately in central area is located on the sash, and with on at least one of the longitudinal struts of the sash arranged guide element, the Swing open the sash along one of the Skirting trained guideway moves, as well with at least one serving as a vibrating aid Spring device.

Under swing-wing roof windows are windows too understand whose frame is built into the roof are and their sash around an approximately in the center of the wing frame axis swingable are. Such swing-roof windows have the advantage that, for example, to clean the Outside of the glazing around the swing axis so can be widely pivoted that the outer glass surface can be cleaned from the interior. The swing axle thus not only offers the possibility the ventilation position, but also also a simple outer glass cleaning.

Furthermore, roof windows, in particular roof windows, known, which formed as a folding window are, that is, the casement is in the area the upper frame cross-profile pivotally mounted. While in a swing window due to the focus near arrangement of the swing axle when Open a not too big torque applied must be due to a flip window of the weight generated by the sash Torque a correspondingly greater force for a Opening the window necessary.

There are also known swing windows, the both a folding movement and a swinging motion allow the sash. The present here The invention relates to swing windows or else with folding swing windows. This means, The sash is around one in its middle Area lying swing axis movably mounted.

To be a special in a swing-wing skylight to achieve cost-effective construction is It is possible to use the swinging wing with simply braked To equip pivot bearings as accurately as possible in the middle of the side rails of the sash lie, so that the window wing in terms of weight about balanced. But are-one other design- the pivot bearing while still in the middle Area, but not exactly in the middle of the Side bars of the sash, so can be opened Windows realize a better headroom, However, due to the weight distribution now a spring device required which supports the opening movement, so that the Torque is caught in the direction of the Closed position acts.

Swing when the roof window swings open the subframe profiles corresponding to the longitudinal beams of the Wing frames are assigned, from the sash path. For this it is necessary that the sash on the frame by means of at least one guide element to be led. Preferably, everyone will Longitudinal member of the frame associated with a guide element, especially in the form of a guide pin is trained. This side to the outside projecting guide elements go through in the Oscillation of the roof window each have a guideway. Since the swing axis spaced from the respective guide element of the sash lies, become during the swing opening movement the subframe profiles issued at the same time the respective guide element extending along the guideway emotional.

It is from the German utility model 1 818 630 known that trained as a sliding pin Guide element laterally along a groove moved in the frame of the skylight. adversely in this construction, the relatively expensive Production, due to the formation of the grooves. Furthermore, the assembly is difficult and expensive because when mounting the wing, the guide elements in the grooves must be introduced. The nature of Suspension of the wing requires a sash with a relatively large thickness and a deep intervention of the sash in the frame.

From German Patent Application 31 21 322 is a Swing-wing skylight known in which the as a sliding pin trained guide element the swing opening movement along a guideway along the surface of the window frame emotional. Furthermore, this known roof window a spring device, which the swing opening movement supported. Located on the frame in addition to spring-biased pivot arms, attached to their Free ends carry rollers, which are on the sash support and in this way the Support swinging process. The guideway Each longitudinal spar of the frame is located in the upper Half and the associated spring-loaded Swivel arm in the lower half of the frame, so that the two elements do not interfere.

The invention is based on the object, a roof window indicate that a spring assisted Swing opening allows, with the swinging aid should be designed as inconspicuous as possible and preferably relatively narrow side rails of the frame can be used.

This object is achieved according to the invention that the spring device is formed telescopically is and with her one end on the sash is pivotally attached and with her other, free end with a receptacle on the frame releasably cooperates, and that the recording a Has passage for the guide element. By the telescopic design of the spring device is realized a swinging aid that is inconspicuous and easy to implement. By the Telescopic design has the spring device essentially a longitudinal extension, wherein her one end pivotally on the sash is attached and her other end to one Supporting the picture on the frame. This support takes place only in the swing opening phase of the casement. If the window continues to open, so picks up the free end of the recording. A preferably associated with each longitudinal spar of the sash Guide element moves in the Swing opening or swing closing movement along one guideway on the frame, each preferably on the surface of the frame lies. In the course of the opening movement a collision of the corresponding guide element with the associated spring device to avoid, that is, to block the opening movement to prevent is according to the invention provided that with the free end of the spring device cooperative reception a passage way having for the associated guide element. Thus, the recording allows the support the spring device, however, wherein the guide element the recording can happen without that the guide element from a certain swinging position of the sash against the free end of the Spring device occurs and in this way hinder the opening movement of the sash would.

In the course of the following explanations will only on a guide element and only one receptacle, one Fed device and so on, though preferably on each side of the skylight each such elements are. in principle However, it is also possible that only one side of the Roof window is equipped with these elements, but what a higher load (twist and so further).

According to a development of the invention is provided that the recording one by emergence of the Guide element has displaceable area. Due to the displaceable area, its displacement movement by the emergence of the guide element takes place, is the passing of the guide element possible. The relocation is preferably done by the formation of a pivot axis. The Support of the spring device takes place on the displaceable Area, where there is preferably an abutment, for example, a receiving recess, is formed, in which the free end of the spring device can intervene.

The guide element may be preferred as a guide pin be educated. The pivot axis of the movable Area preferably runs parallel to Longitudinal extent of the central axis of the guide element, in particular of the guide pin.

It is advantageous if the passage of the recording is designed as Passierkanal. For example It is possible that the recording is a lateral Has groove or formed as a U-profile, wherein the guide element, the groove or the inside of the U-profile in the course of the sash movement happens. The groove or the interior of the U-profile thus forms the Passierkanal.

In particular, it is provided that the guideway is formed straight. However, it can be -after another embodiment also provided be that certain areas of the guideway up higher or lower level lie other areas, that is, that the Guide element when passing through its guideway occupies different height levels.

It is preferably provided that on the guide element and / or at the displaceable area at least a shift slope is formed. This Displacement slope supports the evasive movement of the displaceable area, hence the guide element can happen.

The passageway may preferably be in opposite Passing directions of the guide element happens be, that is, at the opening movement of Window becomes the guideway in one direction and at the closing movement in the opposite Go through the direction. That's why it is advantageous if at least two shift slopes are provided, namely, a, at Opening operation of the roof window, the guide element let pass and another shift slope, in the closing movement of the Roof window comes into function, so when going through of the guide element in the opposite direction also deflects the displaceable area, so that a passage is possible.

It is also advantageous if in the guideway a clamping fixation for the guide element is located. This clamp fixing allows the skylight to fix in swing open position, so that it - even with light wind pressure and so on - not uncontrolled changed the position. The clamping fixation can for example be formed on the receptacle be or in an area of the guideway spaced to accommodate.

The longitudinal extent of the guide element runs transverse to the longitudinal extent of the spring device. Due to the telescopic design of the spring device can be spoken of a longitudinal extension be, depending on the opening position the Dachfensters- to the longitudinal extent of the guide element, in particular of the guide pin, included a different sized angle is.

It is also advantageous if the guide element into the field of recording, in particular until protrudes into the area of the anvil. This embodiment allows the side beams of the skylight, especially the side rails of the frame, very narrow form, due to the passage way yet the collision between spring device and guide element excluded is. In particular, the guide element can be about in half projecting into the area of the receptacle, that is, abutment and guide element overlap at least partially, due to the passage way yet no blocking of the opening movement he follows.

According to another embodiment of the invention is provided that the passage of the recording as Overflow survey for overflow of the anvil is trained. This embodiment makes it possible the counter bearing, in particular its training as Receptacle, such that the free end of the spring device safely added that is, so that the free end is not from the counter bearing can slip out. Because the guideway of the Guide element overlaps the counter bearing, wherein formed according to the invention an overflow survey is, it is possible, preferably cup-like To obtain counter bearing in its shape, since the guideway is on a different level, namely due to the overflow elevation above the cup-like counter bearing is located.

Finally, it is beneficial if the overflow collection a Auffahrabschnitt and a Abfahrabschnitt for the guide element, the means, during the opening movement that moves Guide element along the Auffahrabschnittes to to reach the higher level of the overflow survey. In the course of the further opening movement is then leave this higher level again by the guide element moves down the take-off section. The same applies to the closing movement of the roof window, wherein the Abfahrabschnitt then happens first, that is, this works then as a Auffahrabschnitt, and then the previously referred to as Auffahrabschnitt section happens, this then as a departure section acts.

FIG. 1 shows a residential roof window 1 in a side view, which is in the open oscillating position. The dormer window 1 is a folding swing-wing skylight educated. It points a frame 2 and a sash 3. The for installation in a roof, not shown provided frame 2 has two parallel mutually spaced extending longitudinal beams. 4 and two also spaced apart in parallel extending transverse beams 5. Accordingly, the sash 3 with two spaced apart in parallel extending longitudinal beams 6 and two parallel spaced apart extending cross beams 7 equipped. The two longitudinal beams 6 of Sash frames 3 point in the area of their sections 9 subframe profiles 10, which on the frame 2 in the area of -in the installation position upper- crossbar 5 about a horizontal axis 11 and the sash 3 pivotally mounted about a horizontal axis 12 are.

Is the sash 3 in the closed position, so the subframe profiles 10 are parallel on the longitudinal bars 6 and are in this position fixed. If the operating handle 8 in the folding position pivoted, so remain the subframe profiles 10 coupled in parallel with the longitudinal beams 6, and there is a pivoting of the sash 3 about the axis 11 in the folded position possible. Becomes the operating handle 8 spent in swinging position and the roof window 1 is opened, the in Figure 1 drawn position taken in the a decoupling of the subframe profiles 10 of the Longitudinal members 6 of the sash 3 is present, so that the subframe profiles 10 with respect to the longitudinal beams 6 pivot about the axis 12 in an angular position. At the same time, the overall arrangement pivots about the axis 11. To realize this movement is on the outer sides 13 of the longitudinal beams 6 respectively a guide member 14 fixed on the Surface 15 of the longitudinal spar 4 of the frame 2 supported. The axes 11 and 12 and the guide element 14 are as apparent from Figure 1in the swing opening position shown there on vertices of an imaginary triangle. insofar has the guide member 14 from the axis 12 a Distance up. The axis 12 forms a swing axis, which allows the sash frame 3 to a maximum of about 180 °, reducing the outside of the sash 3 facing the frame 2, so that for example the outside of the glazing from the room can be cleaned forth. Furthermore, the Swing axle an extremely wide window opening, like it emerges from the figure 2.

From Figures 1 and 2 it is further apparent that at each longitudinal spar 6 of the sash 3, pivotally about a horizontal axis 16, a spring device 17 is arranged, each one Oscillating aid 18 when opening the residential roof window. 1 forms. The spring device 17 is telescopic educated; It has a housing 19 in which there is a helical compression spring, not shown located, with an axially displaceable operating rod 20 cooperates. On to the operating rod 20 opposite end of the housing 19th a fixed support rod 21 is attached, the with a receptacle 22 attached to the frame 2 can interact. Instead of using mechanical Spring element formed spring device 17 is It is also possible that a gas spring used passes, wherein the housing 19 then from the cylinder the gas spring and the actuating rod 20 of the piston rod of the gas spring are realized. This applies to all embodiments of the Characters. The housing 19 facing away from the end of the actuating rod 20 has an actuating rod head 23, which is pivotable about the axis 16 at the Sash frame 3 is mounted. Preferably, the Swivel angle by suitable, not shown Slings within a certain range limited to prevent wide open Window the spring device 17 in a rotational position in which they take the view from the side Could hinder windows. The end 24 of the support rod 21 forms a free end 25 of the spring device 17. This means that from reaching a certain opening position of the window of the recording 22 can lift off, as can be seen from the figure 2 shows. The receptacle 22 has an abutment 26 in the form of a receiving recess 27, in which the free end 25 of the spring device 17th can occur. In this way it supports itself the spring device 17 on the one hand on the frame 2 and on the other hand on the sash 3, so that -im Window one start swinging area Opening aid is done. According to Figure 2- the Roof window 1 with respect to the position of the figure 1 further open, so the guide element shifts 14 in the direction of that shown in the figure 1 Arrows 28, that is, it enters the area of the recording 22. A comparison of the figures 1 and 2 shows that it is in the swing opening movement of the residential roof window 1 from one position left side of the receptacle 22 in one position the right side of the receptacle 22 passes. To this to realize, so no collision with the recording 22 and / or the spring device 17 (or its fixed support rod 21) to bring about, is the recording 22 with a Passierweg 29 provided for the guide member 14. The closer Design of this Passierweges 29 goes out Figures 1 and 2 not apparent, but is in Course of further figures explained in more detail. As already mentioned, the guide member 14 moves in the course of the opening movement or the Closing movement of the residential roof window 1 along the Surface 15 of the associated longitudinal spar 4 of the Frame 2. Insofar there is a guideway 30 formed for the guide member 14, wherein This guideway 30 also by the recording 22 extends therethrough. According to the embodiment of Figures 1 and 2, this guideway 30 is flat educated.

The guide element 14 is shown in detail in FIG shown. It has a side from the longitudinal spar 6 of the sash 3 protruding bolts 31 on, on the -drehbeweglich- a sliding block 32 is arranged is. The sliding block 32 is located with a Support surface 33 on the guideway 30 of the frame 4, wherein the material properties and -ausgestaltungen are chosen so that a desired Friction value is achieved to prevent the window itself after spending in adjusted a desired opening position. Of the Slider 32 has on opposite one another Pages each have a shift slope 34 or 35, which cooperate with the receptacle 22. This will be discussed in more detail below.

According to FIGS. 4 and 5, the receptacle 22 has a base plate 36 as well as over the plane 37 of the base plate 36 levitating bracket 38. Da the receptacle 22 symmetrical to a transverse center line 39 is formed, is only below on one half of this component. The other half is then designed accordingly. In a stepped recess 40 of the side surface 41 of the bearing block 38 is a stud 42nd arranged, which has a pivot axis 43 for a displaceable Area 44 of the receptacle 22 forms. Of the displaceable area 44 thus forms a tilting part 45, which is a substantially solid center part 46 and on opposite sides narrow tab 47 and a bearing arm 48 has. The bearing arm 48 is by means of a bearing bore 49 pivotally mounted on the stud bolt 42. At its top 50 is in the middle part 46th the counter-bearing 26 in the form of the receiving recess 27th educated. The flap 47 is with a displacement slope 51 and the middle part 46 with a further displacement slope 52 equipped. On the top 53 of the bearing block 38 is a return spring 54 in the form of a leaf spring 55 by means a fastener 56 is arranged, wherein the leaf spring 55 with its free end up extends to the tilting part 45. This will be the Tilting 45 in the resulting from Figures 4 and 5 Position reset when it comes to the Swivel axis 43 in the direction of the registered in the figure 4 Arrows 57 was pivoted.

From Figures 4 and 5 it is apparent that the tilting part 45 on the right side of the Lagerbokkes 38 is attached. Because of the symmetrical However, it is also possible to design it the other side of the bearing block 38 in the corresponding Way to attach, where it is but not then around the identical tilting part 45 but a mirror image design. So it is not necessary for each of the two longitudinal beams 4 of the frame 2 create customized shots 22, but it can with regard to the base plate 36 and of the bearing block 38 one and the same part used be, in which case only different tipping parts 45 are used. The leaf spring 55 can be retained, as they are around the fastener 56 can be twisted so that they can with their free end in each case with the tilting part arranged there 45 cooperates. For fixing the position of Recording 22 on the longitudinal beam 4 are at the bottom 58 of the base plate 36 positioning pins 59 arranged in the corresponding holes in the frame 2 intervene. The attachment takes place by means of unillustrated threaded screws, the pass through the screw holes 60 of the base plate 36. The screw holes 60 are in the range of corresponding middle part 46 of the tilting part 45 is arranged, that is, the tilting member 46 is corresponding turn up in accordance with arrow 57, which then the accessibility to the corresponding screw head given is.

According to FIGS. 6 and 7, the receptacle 22 a passage 29 for the guide member 14. The Passierweg 29 forms part of the guideway 30 and is due to the U-shaped profile (Figures 6 and 7) of the receptacle 22 as Passierkanal 61 designed. This Passierkanal 61 is in Course of the swing opening or swing closing movement of the dormer window 1 from the guide element 14 go through. To a flat guideway 30 form, the base plate 36 in the surface 15 of the frame 2 is inserted (see in particular Figures 6 and 7).

For fixing certain opening positions of the Roof window 1 is a clamp fixation 62 for provided the guide member 14, wherein these Klexnmfixierung 62 preferably by means of recording 22 is created, in such a way that the free height h of the passage 61 slightly smaller than the Thickness of the guide member 14 is formed, so that there is a slight clamping. This elastic compliant clamping is preferably realized by that in a leg 63 of the U-shaped Profile of the receptacle 22 an open-edged recess 64 is located, in which a spring body 65, For example, a rubber is introduced. On this way can be the adjacent wall part Dodge 66 with compression of the spring body, when the passage 61 from the guide element is passed through, at the same time a Clamping pressure is exerted on the latter. It is also possible that in contact with the guide member 14 reaching wall surfaces of the passage 61 are provided with a surface roughness. This may additionally or alternatively only when Guiding element 14 be realized.

FIGS. 8 to 18 show a further embodiment the invention, in which the passage 29 for the guide member 14 in a different way realized in the preceding embodiment is. In FIGS. 8 to 18 are opposite Figures 1 to 7 the same parts with the same reference numerals hereinafter only to discuss the differences. According to the Figures 8 and 9 is located over the longitudinal extent the guideway 30 at the swing opening of the living roof window 1 first as a separate Unit formed clamping fixation 62, then the receptacle 22, a stop and holding part 67th for the guide member 14 follows. The clamping fixation 62 is more apparent from Figures 16 and 17. It has a trained as a groove Passier 61 on which a clamping action on the not shown in the figures, guide element 14 exercises. The guide element 14 is according to Figure 10 formed as a guide pin 68. However, it is also-for other embodiments possible, another shape for the guide element 14 or also provide one Insert sliding block.

The receptacle 22 has in particular according to the figures 8, 9 and 11 a passageway 29 which in Form of an overflow elevation 69 is formed, the extends above the thrust bearing 26 and thus an overflow of the guide member 14 of the abutment 26 allowed. As with the previous one Embodiment, the receptacle 22 to a transverse center line 39 formed symmetrically, so that below only on the embodiment of a Half is received. The counter-bearing 26 is in Formed a receiving recess 27, the laterally into the overflow elevation 69 trough-shaped is incorporated. Such a recording 27 is located in the area of each flank of Overflow survey 69 (according to the symmetrical design). Since the two are facing each other to the transverse line 39 opposite receiving recesses 27 marginally spaced to the side surface 70 of the receptacle 22nd are arranged, the convex profile 71 remains the Overflow survey 69 obtained according to Figure 11. This This has the consequence that in the course of the opening movement the overflow elevation 69 overflowing guide element 14 also in the area of receiving cavities 27 is raised, so not with the abutments 26 collided. FIG. 12 shows by means of the double arrow ü the overlap length of the guide element 14 with the receptacle 22. It can be seen that the free end of the guide member 14, the receiving recesses 27 happen, but due to the Edge distance of the receiving recesses 27 to the side surface 70 a bearing surface 72 in this area exists, so that the convex profile 71 traveled can be.

From FIGS. 14, 15, 16 and 17 it can be seen that on the receptacle 22 and the clamping fixation 62 positive locking elements 73, 74 are adapted to a aligned and positionally accurate joining this To be able to realize parts. It is there too possible that - not as in the figure 12- two for Center cross-line 39 mirror-image parts of the picture 22 present, which together or in one piece also formed composed of two parts but that one half according to the figures 14 and 15 combined with a clamp fixation 62 becomes. This means that during the opening movement of the residential roof window 1, the guide element 14 first the clamping fixation happens and then for receiving 22, which according to the figures 14th and 15 is configured. As is the guideway 30 in the receptacle 22 according to FIGS. 14 and 15 at a higher and a lower level It is necessary that the to the Recording 22 subsequent, the clamping fixation 62nd remote part of the guideway 30 on the higher Level must be, so that the guide element 14th the entire guideway 30 pass steplessly can (not shown in the figures).

The embodiment of Figure 18 differs only from the embodiment of FIG in that the guideway 30 is not on the surface 15 of the longitudinal spar 4 of the frame 2, but that this guideway 30 - according to Figure 18- "lowered", ie in Falzluftbereich is located.

Below is briefly on the operation the two embodiments according to the figures 1 to 7 and 8 to 17 are received. Will that be Roof window according to the figure 1 from the closed position opened in an initial swing position, so this movement is by means of the spring device 17 supported. In the course of the opening movement slides the guide member 14 via the guideway and - after reaching a corresponding Opening position- in the clamping fixation 62 of the recording 22. Will the window be beyond this position? open, so leave the guide member 14 the Recording 22, that is, it passes through their Passierkanal 61, wherein by accumulating the shift slopes 34 on the displacement slope 52 a Pivoting of the displaceable area 44 takes place, thus a collision with the receiving recess 27 or the support rod 21 is avoided. Even if the support rod 21 is in the receiving recess 27 is due to the swinging up of the displaceable portion 44 passing respectively. When closing the residential roof window 1, a correspondingly reverse movement takes place, that is, the guide member 14 passes through the guideway 30 in the reverse direction, wherein then in the area of the receptacle 22, the shift slopes 35 and 51 interact. In the course of this Closing movement occurs the free end 25 of the spring device 17 in the receiving recess 27 a.

If the living roof window 1 according to the figures 8 to 17 or the roof window according to the FIG. 18 is opened, as it passes through as a guide pin 68 trained guide element first the formed on the surface 15 of the longitudinal spar 4 Guideway 30 and then enters the clamp fixation 62 on. This clamp fixation 62 can also as shown in Figure 7 also with be designed elastic clamping means. Will that be Window open further, so overflows the guide pin 68 the overflow collection 69 without him is obstructed by the receiving recess 27, However, initially the support rod 21 from the receiving recess 27 must emerge before at this point a passing of the guide element 14 can take place. The opening of the window 1 can up to the position of Figures 9 and 18 take place, in which the guide pin 68 in the hook-shaped stop and holding part enters and there learns a fixation. When closing the Roof windows 1 done the previously described Operations in a correspondingly reverse manner.
