Description

The invention relates to a roof window, in particular roof windows, with a side rails having frame and with a top cross member having wing frame having a Drehgleitführung in the region of its upper transverse spar whose Gleitführungsbahn extends over at least one of the side rails or at least a portion of the side member of the frame at least one side rail an auxiliary lever is assigned.

From the international patent application WO 00/28184 For example, a window is known which has a frame and a sash. The casement is connected to the frame via a Drehgleitführung in conjunction. Further, a telescoping auxiliary lever is provided, which extends between the frame and the sash. A telescopic portion of the auxiliary lever communicates with a handlebar lever, which leads to the frame. The known construction is relatively expensive and requires special components due to the telescoping function.

The invention has for its object to provide a simple and reliable roof window, which is easy and safe to install, easy to use and maintainable. Furthermore, the skylight should have a high density and require low operating forces.

This object is achieved in that the auxiliary lever at a fixed distance from one another attacking the frame, Having fixed relative to the frame fixed frame pivot bearing and an attacking on the casement, relative to the wing frame fixed wing frame pivot bearing. Consequently, the sash is held only on the Drehgleitführung and the auxiliary lever on the frame so that a folding position can be brought, which is convertible into a rotational position of the wing of the roof window, in which the outer side of the sash facing the outside of the window frame or substantially facing , Accordingly, the subject matter of the invention, a further folding function (also called tilting function), since from the folding position, the rotational position of the wing can be realized. The structural complexity is this very low, since in addition to the rotation slide only the auxiliary lever is to be realized, with rotary slide and auxiliary lever can be created as standard components easily and inexpensively. The folding opening of the residential roof window according to the invention represents a ventilation position, which is intensified due to the transfer into the rotational position of the wing. In the end position of the rotary position of the window sash takes a position whose main benefit allows easy cleaning of the outer pane from the room. Consequently, there is a cleaning position. The flap of the wing of the roof window according to the invention takes place about an axis of rotation which lies in the region of the upper transverse spar of the casement or of the upper transverse spar of the frame. If the wing is moved into the rotational position, the rotary sliding guide ensures that the upper transverse spar of the sash can slide or roll along at least one sliding guideway guided on at least one of the side rails. The auxiliary lever holds the window sash at least a side, preferably in the middle region, which is approximately between the second to fourth fifth of the height of a five-fifths high wing. In an intermediate position, the plane of the sash or the wing assumes a 90 ° position to the plane of the frame. The upper cross member of the sash is - in the course of the further opening movement - moved further down on the side rail or the side rails of the frame, so that the outer side of the sash faces the outside of the window frame. If in the course of this application of upper cross member, outside, etc. is spoken, so this is based on the closed position of the roof window, in particular roof window.

It is preferably provided that the frame pivot bearing is at least at the same height or above the axis of rotation of the rotary slide. The term "at the same height" or "above" refers to the installation position of the roof window, ie in an oblique position on the roof, wherein the information "at the same height" or "above" in the vertical direction and / or in the longitudinal direction of the side rails of the window frame you can see. Consequently, the Drehgleitführung the sash is at the same height below the frame pivot bearing. The above applies regardless of the sash position of the roof window.

According to a development of the invention it is provided that the casement pivot bearing is located below the axis of rotation of the rotary slide. This is based on the mounting position on the roof, so the inclination of the roof window and based on the closed position of the wing.

According to a development of the invention, it is provided that the sliding guideway extends so far that in an end position the outside of the sash is facing or facing the outside of the frame. In this end position is in particular a cleaning position, that is, the outer pane can be cleaned from the room.

It is advantageous if the casement frame has a circumferential or substantially circumferential overhang relative to the frame. This supernatant is also referred to as a rollover. Accordingly, the invention relates to a roof window, which allows flaps and a turn of the wing, the wing can be rotated in particular for cleaning so far that the outer pane is accessible, although a circumferential or substantially circumferential projection of the sash to the frame is present. By the supernatant a very good airtightness is achieved in the closed position. Furthermore, low opening and closing forces can be realized, as occurring friction in moving the wing due to a present Überstanddichtsystems (also called impact seal system) is minimal. Furthermore, a high dimensional stability is ensured by the circumferential or substantially circumferential overhang, wherein the impact gasket already mentioned is improved in comparison to lip or sliding seals. In contrast to the sliding seals, the article of the invention does not cause a relative abrasion movement in the sealing area due to the impact seal. The invention also provides an improvement in terms of aging and resilience of the seals. The mentioned flashover also creates optical tightness.

Even without seals no or only a minimal incidence of light through the gap between glare and sash. Due to the procedure according to the invention, an additional frame or additional profiles used today in comparable products, which / which either clipped or screwed forms a projection and thus a stop surface for a seal or the like, is eliminated. It also eliminates a Wegfräsen the supernatant in known windows in the area in which the casement swings into the frame. Furthermore, a high security against sagging of the casement, for example due to material aging, material fatigue, etc., as well as under compressive stress (for example, by wind pressure, snow load, etc.) given from the outside.

The rotary slide guide is in particular designed such that rotation of the sash frame occurs outside or substantially outside the window frame. Compared with known roof windows, in which the casement swings through the frame, the object of the invention is provided that the rotation of the casement outside of the frame occurs.

The axis of rotation of the rotary sliding guide is preferably located in the upper region of the upper transverse spar of the sash.

Preferably, the auxiliary lever, an opening spring, opening gas spring and / or a motion damper be assigned. Such an element is connected to the auxiliary lever on the one hand and with the frame on the other.

A further development of the invention provides that each side member has a sliding guide track and each upper transverse member end is assigned a guide element for the sliding guide track. As a result, the wing is guided on both sides. The guide elements are preferably designed as pins, which are guided in Gleitführungsbahnen forming slide grooves of the side rails. A rotation is possible around the pins. Furthermore, in addition, a sliding or rolling, so a linear movement, take place.

It is advantageous if each side member is assigned an auxiliary lever. Thus, the wing is guided on both sides.

Finally, it is provided that each auxiliary lever is associated with an opening spring, opening gas spring and / or a motion damper.

FIG. 1 shows a skylight 2 designed as a living roof window 1, which has a window frame 3 and a wing frame 4. The frame 3 occupies a sloping position relative to the horizontal or vertical, as it corresponds for example to a roof pitch of a pitched roof.

The frame 3 has according to Figures 1 and 2, two mutually parallel side rails 5 and 6 and a top cross member 7 and a lower cross member 8, wherein the upper cross member 7 and lower cross member 8 parallel to each other and each at a 90 ° angle to the side rails. 5 and 6 extend. The wing frame 4 has according to Figures 2 and 3 parallel to each other side bars 9 and 10 and a top cross member 11 and a lower cross member 12th top cross member 11 and lower cross member 12 parallel to each other and are in 90 ° angles to the side rails 9 and 10 respectively. In the area the upper transverse spar 11 of the casement 4 is a Drehgleitführung 13, which in the region of the upper Querholmenden 14, 15 each designed as a pin or roller guide member 16, 17, wherein the guide elements 16, 17 in Gleitführungsbahnen 18, 19 of the side rails 5, 6 of the Blendrahmens 3 are guided so that the sash 4 can perform a folding movement and / or a linear sliding movement.

Each side rail 5, 6 and 9, 10 is an auxiliary lever 20, 21 assigned. Alternatively, it is also possible-as shown in FIGS. 1 and 2-that only one auxiliary lever 20 is provided, that is, the casement 4 is guided on the frame 3 only on one side of the roof window 2 by means of an auxiliary lever. However, below is always assumed by two auxiliary levers 20, 21, but for the sake of simplicity, only the auxiliary lever 20 will be described. The execution with respect to the auxiliary lever 21 is then corresponding.

The auxiliary lever 20 is formed as an integral, constant length in the lever. He has at its one end 22 a frame pivot bearing 23 and in the region of its other end 24 a sash 25 pivot bearing. Blend frame pivot bearing 23 and sash pivot bearings 25 are arranged stationary with respect to the position of the frame 3 or sash 4 and have a fixed distance from each other. This distance is constant and essentially determined by the length of the auxiliary lever 20. By means of the auxiliary lever 20 of the sash frame 4 is guided and held with the aid of the Drehgleitführung 13 on the frame 3 when folding open or rotary opening. By means of the frame pivot bearing 23 is the one end 22 of the auxiliary lever 20 with the frame 3, in particular with the associated side member 5, connected; by means of the casement pivot 25, the other end 24 of the auxiliary lever 20 is connected to the casement 4, in particular to its side rail 9. Both compounds are designed as rotary joints. The Gleitführungsbahnen located in the side rails 5 and 6 18 and 19 have guide grooves 26 and 27, wherein the guide grooves 26 and 27 along the longitudinal extension of the side rails 5 and 6 extend. This course takes place in particular over a portion of the length of the side rails 5 and 6 or over the entire length of the respective side rails 5 and 6. In the guide grooves 26 and 27 engage the pin members formed as guide elements 16 and 17, whereby the casement 4 opposite the frame 3 can be both pivoted and guided linearly.

By means of an opening gas spring 28, the opening movement of the sash 4 is supported. The opening gas spring 28 engages with a End 29 on the side rail 5 of the frame 3 in the upper half and is connected to the other end 30 with the auxiliary lever 20. Both compounds of the opening gas spring 28 to the frame 3 or sash 4 are rotatably formed. The opening gas spring 28 is formed as a telescopic gas spring, which generates an opening pressure. The connection of the opening gas spring 28 with the auxiliary lever 20 is approximately in the central region of the auxiliary lever 20, preferably in the upper third. Instead of or in addition to the gas spring and a tension spring and / or a torsion spring can be used.

It follows from all this that the casement 4 is held on the frame 3 of the roof window 2 only in that on the one hand there is a Drehgleitführung 13 and on the other hand, at least one auxiliary lever 20. Further measures are not taken. The opening gas spring 28 is not to be understood as a guide means, but merely serves as a display aid for the folding opening movement of the sash 4.

From the figures 10 and 11 it can be seen that in the closed position resting on the frame 3 sash 4 has a projection 31, which is also referred to as a rollover. This is a section of the side rails 9 and 10 and the lower cross member 12 and optionally the upper cross member 11 of the sash 4, which engages over the frame 3. Preferably, according to FIG. 10, the respective spar of the casement 4 is provided with a stepped recess 32 into which a corner region 33 of the respective spar of the frame 3 engages in the closed position of the skylight 2. The so formed protrusion 31 is formed as a circumferential or substantially circumferential projection 31, that is, it is located on all spars or almost all spars or in some areas on the spars or almost all spars of the sash 4. In the closed position emerges accordingly - according to Figure 11 - the sash 4 a quasi a little way into the frame 3 a. From this it is also clear that with a substantially circumferential overhang 31 no rotation of the sash 4 is possible such that a portion of the sash 4 passes through the opening of the frame 3, as this is prevented due to the supernatant 31. The opening operation of the sash 4 or wing relative to the frame 3 is such that for tilting first pivoting of the sash 4 about a rotation axis in the region of the upper cross member 11 takes place and that then - in the course of a further opening movement - the sash 3 with its upper transverse spar 11th or the there acting rotary slide 13 is moved along the sliding guide rails 18 and 19, wherein in the course of further movement of the entire casement 4 rotates such that - according to Figure 12 - the outside 34 of the sash 4 of the outside 35 of the frame 3 is facing. Accordingly, from the interior of a room, which is associated with the roof window 2, the outer pane 36 (Figure 10) are cleaned. The arrow 37 in Figure 12 indicates how moves in the course of the opening movement of the upper cross member 11 from top to bottom on the side rails 5 and 6 of the frame 3 and the arrow 38 of Figure 12 indicates, as at the same time the lower cross member 12 of the Sash frame 4 moves upwards.

Hereinafter, the mentioned opening movement will be explained in detail again with reference to FIGS. 3 to 9.

In Figure 3, the closed position of the residential roof window 1 is shown. Accordingly, an arrangement according to FIG. 11 is present. It can be seen that the auxiliary lever 20 extends parallel to the casement 4 or frame 3 in the region of the side rails 5, 6 and 9, 10. The opening gas spring 28 assumes a slightly inclined position relative to the auxiliary lever 20.

If - as shown in FIG. 4 - the living roof window 1 is folded open to a certain extent, the sash frame 4 pivots about the axis of rotation 39 of the rotary sliding guide 13, that is, the guide elements 16 and 17 designed as pins rotate into the guide grooves 18 and 19 forming guide grooves 26 and 27. Simultaneously, the auxiliary lever 20 pivots in the frame pivot bearing 23, but it continues to extend parallel to the sash 4.

If now - in the course of further opening - the position shown in Figure 5 occupied, then a further pivoting about the Drehgleitführung 13 and the frame pivot bearing 23 is carried out and the maximum folding opening position taken. This hinged opening is supported by a correspondingly wide relaxation of the opening gas opening by the opening process 28th

If now - according to Figure 6 - the opening movement continues, that is, the sash 4 still further pivoted, so start the guide elements 16 and 17 in the Gleitführungsbahnen 18 and 19 a linear movement along the side rails 5 and 6 of To perform Blendrahmens 3, wherein at the same time the sash 4 performs a further rotational movement about the guide elements formed as a pin 16 and 17. Furthermore, the auxiliary lever 20 releases from its parallel position to the casement 4, that is, he takes according to Figure 6 by its rotation in the sash pivot 25 an acute angle to the sash 4.

If the casement 4 is opened further, as shown in FIG. 7, the acute angle increases and the guide elements 16 and 17 continue to shift in the guide grooves 26 and 27. In FIG. 7 casement 4 and frame 3 are at right angles to each other.

In Figure 8, the opening operation is still further, that is, the sash 4 begins to rotate so far from the frame 4 that the outer side 34 of the sash 4 begins to orient in the direction of the outer side 35 of the frame 3.

In Figure 9, the end position of the rotational movement of the sash 4 is reached, in which the guide elements 16 and 17 have moved even further in the direction of the lower cross member 8 of the frame 3 and the first in the course of the opening movement ever further increasing angle α (Figure 8). between the auxiliary lever 20 and frame 3 has now reduced again.

Closing of the casement 4 from the position resulting from FIG. 9 takes place correspondingly in the reverse manner as described above for the opening process.
