Sunroof, in particular a sunroof with a swinging sash

Technical field

BACKGROUND OF THE INVENTION The invention relates to a sunroof, in particular to a skylight with a swinging sash, with an insertion frame and a window frame, which is supported by a hinged subframe arranged pivotally about an axis, the axis being horizontal and substantially in the central region of the window. and with a guide element arranged on at least one of the longitudinal columns of the window frame which, when the window frame is pivotably opened, moves along a guide formed on the insert frame, and with at least one spring device to facilitate the oscillation.

BACKGROUND OF THE INVENTION

A roof window with a swinging sash means those windows whose insert frame is built into the roof covering and whose window frame is pivotable about an axis extending approximately through the center of the window frame. Roof windows of this type have the advantage that, for example, when cleaning the outer surface of the window glass, the sash may be tilted so that the outer surface of the window glass is inverted inside the room and cleaned there. Thus, the pivot axis allows not only to adjust the sash to a certain position for ventilation, but also to easily clean the outer surface of the window glass.

Furthermore, roof windows, in particular roof windows in living rooms, are designed as hinged, which means that the sash is pivotably mounted at the location of the upper transverse profile of the insert frame, whereas in the case of pivoted roof windows, especially roof windows of greater weight, a great deal of force is required to open the hinged windows.

Combination tilting-swinging roof windows are also known which allow both the tilting and swinging movement of the sash. The present invention relates both to swinging roof windows and to tilting-swinging roof windows. That is, the window frame is pivotably mounted in an axis extending in the horizontal direction approximately through the center of the window frame.

In order to achieve a cost-effective design of the pivoted sunroof, the sash can be equipped with a simple brake rotary bearing, which can be fitted exactly in the center of the longitudinal columns of the sash and the sash can be perfectly balanced. In other constructions where the pivot bearing is not located exactly in the center of the longitudinal pillars of the window frame, greater visibility can be obtained at the top of the sunroof when the sunroof is opened, but due to uneven weight distribution it is necessary to use a spring device to support opening.

The auxiliary frame profiles, which are provided on the longitudinal columns of the window frame, also swing when the swinging sunroof is opened. In this case, it is necessary for the window frame to be guided by at least one guide element provided on the insert frame. The guide element provided on the side sidepiece of the insert frame can be designed, for example, as a guide pin which moves in the guide when the sunroof is opened. Since the pivot axis lies at a certain distance from the respective guide element, the auxiliary frame profiles are adjusted when opening, the element simultaneously moving in the guide.

The German utility model 1.818.360 discloses a guide element formed as a sliding pin which moves in a groove provided on the side of the frame to be inserted. The disadvantage of this construction is the relatively expensive construction due to the groove and the complicated assembly, since the guide element must be inserted into the groove when the window sash is suspended. This kind of hanging window sash

Requires a window frame of relatively large thickness, with a deeper recessed window frame in the insertion frame.

German patent application 3.121.322 also discloses a swing window of a sunroof in which the guide element, which is designed as a sliding pin, moves in a guide provided on the surface of the insert frame. The sunroof is further provided with a spring device which facilitates the pivoting movement of the sash. The insert frame also has resiliently biased swinging arms, the free ends of which are provided with rollers resting on the window frame and thus supporting its swinging. A guide formed on each of the lateral sides of the insert frame is located in their upper half, while the resiliently biased swing arms in the lower half of the insert frame, so that the two components do not interfere with each other.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The object of the present invention is to provide a roof window in which the pivoting movement of the sash is supported by a spring, the support for pivoting the sash should act inconspicuously and whose side edges of the insert frame are relatively thin.

A roof window, in particular a skylight with a swinging sash, with a sliding frame and a window frame, is supported by a hinged subframe arranged pivotally about an axis, the axis being horizontal and substantially in the central region of the window. and with a guide element arranged on at least one of the longitudinal columns of the window frame which, when the window frame is pivotably opened, moves along a guide formed on the insert frame, and with at least one spring device for swinging according to the invention. formed as telescopic and with its one end pivotally mounted on the window frame, the other end of which is a free releasable end, wherein a mounting for the free releasable end of the spring device is arranged on the mounting frame, and The guide is provided with a through groove for the guide element.

By means of a telescoping embodiment of the spring device, it is possible in a simple manner to support the pivoting of the sash by substantially extending it longitudinally, one end of the spring device being pivotally attached to the sash frame while its other end is supported in a seat provided on the blind frame. The support of the opening of the sash by the spring device takes place only in the initial phase of the opening of the sash. If the window is still opened, the free end of the spring device is released from the bearing. When opening, respectively. when closing the sash, the guide element is moved in a guide provided on each of the side walls of the insert frame, the guide being located on the top surface of the insert frame.

In order to avoid collision of the guide element with the spring device, respectively. only blocking the opening of the sash, only the bearing according to the invention is provided with a through groove through which the guide element passes. The mounting thus allows the free end of the spring device to be supported without the guide element extending from a certain opening position of the sash to interfere with the passage groove, thereby preventing the opening of the sunroof.

In the exemplary embodiments of the invention, only one bearing, one guide element and one spring device are indicated, although it is preferred that these components are provided on both sides of the sash. In principle, however, it is possible for these components to be provided on only one side of the sash, which, however, results in a greater load.

According to a further embodiment of the invention, the bearing has a displaceable part due to the guide element, the movement of which is derived from the guide element, which can be effected, for example, by pivoting about a pivot axis formed for this purpose.

-2cz. zyou // B6

The spring device can be supported with its free end just in this displaceable part in which a support is provided for this purpose, for example in the form of a recess,

The guide element can be designed, for example, as a guide pin, whose central axis extends parallel to the pivot axis of the displaceable part.

It is advantageous if the passage through the bearing for the guide element is in the form of a U-shaped passageway or as a lateral groove through which or respectively a side channel. through which the guide element passes.

Furthermore, it is assumed that the guide path of the guide element extends in a straight line. According to another exemplary embodiment, however, the guide path in a certain section may occupy a different height level compared to the other sections, which means that the guide element is at different height levels when moving along the guide path.

The guiding element and / or the displaceable part are provided with at least one incline or an incline. shrinkage, which assist in deflecting the displaceable portion as the guide element passes through the bearing.

Through groove, resp. the passageways are passable by the guide element in both directions, which means that when the sunroof is opened, the guide element moves along the guide track in one direction while it moves in the opposite direction when the sunroof is closed. For this reason, it is advantageous if the guide element and / or the displaceable part are provided with a bevel or a bevel. shrinkage on both sides.

It is also advantageous if there is a clamping element in the guiding path of the guide element which allows the sunroof to be locked in an open position, which should not be changed even in mild wind, for example. The clamping element can be formed, for example, on a bearing or in another section of the guide path.

It is furthermore advantageous if the guide element protrudes up to the bearing area, in particular to the point of abutment. This embodiment allows the side sidepieces of the insert frame to be weaker, and because of the guide path formed on the outside of the side sidings, a collision between the guide element and the spring device is avoided. The guide element can protrude halfway into the bearing, which means that it overlaps at least partially with the support in the form of a recess. Since the guide element extends through the slot at this point, it does not hinder the opening of the sunroof.

According to a further exemplary embodiment of the invention, the guide path of the guide element at the bearing location forms a transition elevation above the support. This embodiment makes it possible to securely support the free end of the spring device in the support, in particular in the recess-shaped support, without spontaneously extending it. The recess may, for example, be in the form of a cup, with the transient elevation of the guide track of the guide element overlapping the recess.

At the same time, it is advantageous if the transition elevation of the guide track is provided with inlet and outlet portions for the guide element, which means that when the roof window opening is moved, the guide element moves the inlet part until it reaches the highest level of transition elevation. As the sunroof opens further, the guide begins to descend from this highest level of transition elevation and passes through the exit section. The same applies to the roof window closing movement, but the guide element first passes through the outlet portion, which then acts as the entrance portion.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a side view of the sunroof 1 in a partially pivoted open position. The sunroof 1 is in the form of a hinged-swinging sash consisting of a window frame 3 and an insert frame 2. The insert frame 2 intended for installation in a roof covering not shown here, consists of two parallel side walls 4 and a lower and an upper crossbeam 5 The window frame 3 also consists of two parallel longitudinal columns 6 and a lower and an upper column 7. Both longitudinal columns 6 of the window frame 3 are provided in the section 9, i.e. above the upper half of the longitudinal columns 6, with auxiliary frame profiles 10 which are pivotably mounted. in the axis 11 at the location of the upper crossbeam 5 and in the axis 12 on the window frame

3.

When the window frame 3 is in the closed position, the auxiliary frame profiles 10 rest on the parallel longitudinal posts 6 of the window frame 3 and are secured in this position. If the control handle 8 is then set to the tilting position of the sash, the subframes 10 remain connected to the longitudinal posts 6 and the window frame 3 can be tilted about the axis 11 to the tilted position. However, if the control handle 8 is moved to the sash position and the sash is opened, it can reach the position shown in Fig. 1. In this position, the auxiliary frame profiles 10 are released from the longitudinal posts 6 of the window frame 3 and set by pivoting about the axis 12 to a position in which they form an angle with the window frame 3.

In order to effect this movement, one guide element 14 is mounted on the outside 13 of the longitudinal posts 6, which is supported on the outer surface 15 of the side frames 4 of the insert frame. The axes 11 and 12, including the guide element 14, as shown in FIG. 1, lie in the open position so shown at the endpoints of the triangle, especially when the guide element 14 is at a certain distance from the axis 12. The axis 12 forms a pivot axis around which the window frame 3 can be swiveled by a maximum of 180 °, i.e. to a position where the outside of the window frame 3 faces the insertion frame 2 and the window glass can thus be cleaned, for example, from inside the room. However, as shown in FIG. 2, the pivot axis allows for even greater opening of the window.

It is further evident from FIGS. 1 and 2 that on each of the longitudinal columns 6 of the window frame 3 there is provided a spring device 17 pivotally mounted on an axis 16 which supports the tilting of the window frame 3. The spring device 17 is telescopic and forms it. a housing 19, in which

A coil spring (not shown), which is not shown in greater detail here, is connected to a control bar 20. At the opposite end, a support rod 21 projects from the housing 19 and is supported in a bearing 22 mounted on a mounting frame 2. a gas pressure damper may be used with the resilient elements, in which the housing 19 then forms a cylinder of the gas pressure damper and a control rod 20 a piston rod. This applies to all exemplary embodiments shown in the drawings. At the end of the control rod 20 there is a head 23 which is pivotally mounted in the axis 16 on the window frame 3. The deflection angle is limited to a certain predetermined range by a stop not shown here, thereby preventing the spring device from resisting side view. The end 24 of the support rod 21 forms the free end 25 of the spring device 17, which means that when a certain window opening position is reached, this free end 25 can be disengaged from the bearing 22, as shown in FIG. In this way, the spring device 17 is supported on one side on the insertion frame 2 and on the other hand fastened on the window frame 3, thereby promoting the opening of the sash in the initial phase. If, as shown in FIG. 2, the sunroof 1 is open even more than the position shown in FIG. 1, the guide 14 moves in the direction of the arrow 28 shown in FIG. 1, which means that it reaches the seat 22. the collision of the guide element 14 with the bearing 22 and / or the spring device 17, in particular with its support rod 21, has the bearing 22 provided with a through groove 29. Although the embodiment of the through groove 19 is not shown in Figs. 1 and 2, . As previously mentioned, when the roof window 1 is opened or closed, the guide 14 moves on the outer surface 15 of the sidewalls 4 of the insertion frame 2. If a guide 30 is provided for this purpose on the outer surface 15 of the sidewalls 4, then this guide 30 extends through the bearing 22. According to the present embodiment shown in Figures 1 and 2, the guide 30 is therefore designed in the form of a planar surface.

FIG. 3 shows a detail of the guide element 14, which is designed as a slide 32 and is rotatably mounted on a pin 31 projecting from the side of the longitudinal column 6 of the window frame 3. The slide 32 bears with its abutment surface 33 on a guide 30 formed on the outer surface. The frame 2, wherein its material properties and shape are free to achieve the desired friction value, which would prevent the sunroof 1 from spontaneously disengaging from the set opening position. Slopes 34, 35 are formed on opposite sides of the slide stone 32 to facilitate passage through the through groove 29 formed in the bearing 22.

Figures 4 and 5 show a bearing 22 consisting of a base plate 36, in whose upper plane 37 a bearing block 38 is formed. Since the bearing 22 is formed symmetrically with respect to the transverse centerline 39, only one half of this design is described in the following description. element. In the stepped recess 40 of the side surface 41 of the block 38, a pin 42 is provided which forms the pivot axis 43 for the movable part 44 of the bearing 22. The movable part 44 is essentially a hinged part 45 consisting of a massive central part 46, opposite side thin projections 47 and A shoulder 26 in the form of a recess 27 is formed on the upper side 50 of the central part 46 in the form of a recess 27. The projection 47, like the central part 46, is provided with chamfers 51 and 52. On the upper side 53 In the block 38, a return spring 54 in the form of an elastic band 55 is fastened by means of a fastening element 56, the free end of which extends beyond the hinged part 45. If the hinged part 45 is rotated around the pivot dog 43 in the direction of arrow 57 shown in FIG. is returned to its original position shown in FIGS. 4 and 5.

It is further evident from FIGS. 4 and 5 that the hinged part 45 is always mounted on the right side of the block 38.

Due to the symmetrical design, however, the hinged part 45 can also be fastened to the opposite side.

In this case, it is not an identical hinged part 45, but in its mirror design. If it is not necessary to use individually adapted bearings 22 for each of the two side walls 4 of the insert frame 2, but to accommodate the same base plate 36 and block 38, only the different hinged parts 45 are required. 55 can be retained, since it can only be rotated by means of the fastening element 56, so that with its free end it always extends above the tilting part 45 arranged here.

Positioning pins 59 are provided on the underside 58 of the base plate 36, which are inserted into respective holes formed in the insert frame 2. The fastening is realized by means of threaded screws (not shown here), which pass through the through holes. 60 in the base plate 36. The through holes 60 are arranged in the region of the hinged part 45, the accessibility of the screw head being achieved by tilting the part 45 in the direction of arrow 57.

Figures 6 and 7 show a bearing 22 with a through groove 29 for the guide element 14. The through groove 29 forms part of the path of the guide 30 and, due to its U-profile, has the shape of a through channel 61 through which the guide 14 passes during opening. closing the sunroof L In order to form a plane guide 30, the base plate 36 is embedded in the outer surface 15 of the insert frame 2.

In order to position the sunroof 1 in a certain open position, the gripping of the guiding element 14, for example in the bearing 22, is formed such that the free height h of the passage channel 61 is slightly smaller than the thickness of the guiding element 14. A recess 64 is formed in one of the jaws 63 of the bearing 22, in which a resilient body 65 made, for example, of rubber, is inserted. Thus, when the guide 14 is passed through the passage 61, the inner wall 66 of the bearing 22 can be bent due to the compression of the resilient body 65, while at the same time exerting a pressure on the guide 14.

Figures 8 to 18 show another exemplary embodiment of the invention in which the through groove 29 for the guide element 14 is formed in another way. In Figures 8 to 18, the same components as in Figures 1 to 7 are designated with the same reference numerals. 8 and 9, above the longitudinal guide 30, there is first a clamp element 62 formed as a separate component, then a bearing 22 and finally a stop 67 for the guide element 14. The clamping element 62, which is shown in more detail in FIGS. The guide element 14 is designed as a guide pin 68. According to other exemplary embodiments, however, the guide element 14 can be made differently, for example. like a slide stone.

8, 9 and 11, the bearing 22 comprises a through groove 29 which is formed in the form of a transition elevation 69 above the abutment 26 and thus permits the guiding element 14 to pass above the abutment 26. The abutment 26 is formed as a recess 27 Both recesses 27 symmetrically arranged with respect to the central axis 39 are arranged at a certain distance from the edge 70, and the transition elevation 69, as shown in Fig. 11, has a convex profile 71. This results in the guide 14 passing through the elevation 69 when opening the sunroof 1 is raised at the recess 27 so that there is no collision with the support 26. The value ii shown in Fig. 12 indicates the length of the overlap of the guide 14 with the bearing 22. It is clear that the free end Although the guide element 14 passes through the recess 27, it is due to the distance of the recess 27 from the edge e 70, a bearing surface 72 is formed at this point so that the guide 14 can extend beyond the convex profile 71.

It is apparent from Figs. 14, 15, 16 and 17 that shaped contact elements 73, 74 are coaxial to the bearing 22 and the clamping element 62, which are coaxial to each other and thus enable accurate positioning of the bearing 22 and the clamping element 62. 14 and 15 can also be mirrored in the axis 39, one of the halves of FIGS. 14 and 15 being combined with the clamping element 62. That is to say, when the sunroof opening movement 1 is moved, the guide 14 first passes through the clamping element. 14 and 15 is once at a higher and once at a lower level, it is necessary that the guide 30 in the clamping element 62 adjoins at a higher level. Thus, the guide element 14 can pass through the entire guide 30 smoothly without any height deviation.

-6GB Z96U77 B6

The embodiment shown in FIG. 18 differs from the embodiment of FIG. 9 only in that the guide 30 is not located on the outer surface 15 of the side sidepiece 4 of the insert frame 2, but is provided below in a specially formed rebate.

The operation of the two exemplary embodiments according to the invention according to FIGS. 1 to 7 and 8 to 17 is explained below. When the sunroof 1 of FIG. 1 is opened from the closed position to the initial pivoted position, this movement is supported by the spring device. 17. At the same time, the guide 14 moves along the guide 30, and when the sunroof 1 has reached a certain opening position, a bearing 22 is formed into the clamping element 62. When the sunroof 1 is further opened, the guide 14 leaves the bearing 22, it passes through its through channel 61, and by sliding 34 on chamfer 52, the movable member 44 is rotated without colliding with the support rod 21. Upon closing of the sunroof 1, there is an inverse movement, with the guide 14 moving along the guide 30 in the inverted direction. The chamfer 35 and the chamfer 51 interact together in the region of the bearing 22 The end 25 of the spring device 17 abuts the recesses 27.

When the sunroof 1 according to the exemplary embodiment of FIG. 18 is opened, the guide pin 68, as a guide element, first moves along a guide 30 formed on the outer surface 15 of the side sidepiece 4 of the insert frame 2 until it forms into the clamping element 62. the element 62 may also be provided with the resilient body 65 shown in FIG. If the sunroof 1 is further opened, the guide pin 68 passes through the elevation 69 without being prevented from moving by the recess 27, but from which the support rod 21 must first come out. The opening of the sunroof 1 can reach the position shown in FIGS. . Giant. 18, in which the guide pin 68 is inserted into a stop 67 by which its position is secured. Upon closing of the sunroof 1, there is an inverse movement, with the guide pin 68 moving along the guide 30 in the reverse direction.
