Description

151349 r

The present invention relates to a skylight with a frame and of the kind specified in the preamble of claim 1 and claim 2 respectively.

Such a skylight is known from German patent specification 1,246,456. According to this specification, the T-shaped guide rail is fixedly fixed to the frame. This guide rail is enclosed by a C-shaped running rail, on which the frame is arranged via a pivotable hinge. The swinging of the frame to open the window can be done manually or by means of a hand-swinging mechanism which lifts the edge of the frame above. An automatic opening of the window with a corresponding oscillation of the frame is not indicated.

An automatic opening skylight is known from German usage pattern 15 2 151349 75 40 055. At this skylight, a pivoting frame is hinged pivotally to the frame by means of hinges, and a laterally displaceable frame is arranged on the pivot frame. According to one embodiment, air pressure springs may be provided which partly attack the frame and partly the rotatable pivot frame. In the case of a closed window, there is an increased pressure in the interior space of these air pressure springs sufficient to automatically move the window to its final position after unlocking. If it is intended to swing the window beyond this final position, at least one pivot of each air pressure spring must be detached from the stop engagement, so that a further swing of the window is not immediately possible.

SUMMARY OF THE INVENTION It is an object of the present invention to further design the roof window 15 which is initially mentioned and known from DE patent 12 46 456, in such a way that, after its unlocking, the window can be opened automatically automatically and, as needed, beyond that piece. .

For the purpose of this purpose, the object 20 initially mentioned is peculiar to that specified in the characterizing part of claim 1 and claim 2, respectively. Further advantageous embodiments of the skylight are set forth in the dependent claims 3-10.

According to this invention, the present invention relates to a skylight having a pane frame which can be pivoted relative to a frame inserted in the roof covering a common edge and is laterally displaced along said edge, a running rail on the frame being slidably mounted on a guide rail mounted on the frame. and the guide rail is pivotally mounted about a shaft relative to the frame, which shaft is pivotally mounted in fixed retaining means fastened to the frame and wherein a helical spring is arranged around the shaft.

In a first of two alternative embodiments, the coil spring is retained with one end of the shaft and with the other end of the guide rail and is below 35 such a bias which initially causes a limited oscillation of the guide rail about the shaft, thereby cooperating from impact to the shaft with impact. on the retaining means, a rotation of the shaft with respect to the holding means prevents, and where there is then the possibility of an additional effect between the stops on the guide rail with the stops on the shaft preventing a rotation of the guide rail relative to the shaft.

In the second alternative embodiment, the coil spring is retained 5 with one end likewise on the shaft but with the other end on the retaining means and is subjected to such biasing which initially causes a limited oscillation of the guide rail and the shaft relative to the retaining means, thereby cooperating between stops. on the shaft and abutments on the guide rail prevent a rotation of the guide rail relative to the shaft, and where a subsequent further oscillation of the guide rail with respect to the axle is possible, during which the interaction between the abutments on the axle and the abutments on the holding means prevents a rotation of the axle in relationship holding means.

15 The swivel mounting of the guide rail ensures two things, namely (a) a rotation of the guide rail in relation to the holding means with a specific piece as a result of the tension of the screw spring after the window unlocking? eg. this rotation must correspond to a turning angle of approx. 25 to 40 °? this angle of rotation corresponds to the angle f \ υ υ between the frame and the frame after the window is automatically opened to a given end position, (b) In connection with said end position it must be possible

rotating the guide rail relative to holding means for 2 R as needed

further opening the window and, if necessary, laying it with its top side on the roof covering; this additional opening should not require any special locking means on the skylight, and may e.g. carried out manually. 1 2 3 4 5 6

The frame consists mostly of a rectangular metal frame with sealing 2 profile and is inserted firmly and permanently into the roof covering. Both at vessel 3, while at the upper and at its lower edge, skirts of flexible material may be provided which facilitate sealing in connection with profiled 5 roofing sheets.

The frame connection with the frame takes place over a running rail which is fixedly mounted on the frame, the running rail can be displaced along a guide rail, which in turn is pivotally mounted in holding means arranged on the frame. The connection of the guide rail with the guide rail is so accurate that this connection causes the lateral displacement of the running rail relative to the guide rail and partly that any rotation of the guide rail in its holding means causes a corresponding swing of the running rail, which in turn leads to a corresponding swing of the frame. with the pane relative to the frame.

10

In order to ensure this precise control, according to a preferred embodiment of the invention, the roof window is formed as stated in the characterizing part of claim 5.

^ After introducing a desired number of balls into each of the two roller guide tracks, the running rail is thereby kept away from the guide rail and can be easily displaced along the latter. The large distance between the two roller guide tracks ensures a good supporting moment, so that even with large attacking forces there is no oscillation of the guide rail relative to the guide rail.

In this embodiment, the precise control can be further increased by the balls being guided without a ball carrier and by the roller guide paths almost completely enclosing the balls. In order to also ensure a uniform distribution of the balls within the roller guide web 2,5 without a ball holder, in each of the roller guide tracks a part of the balls is separated from the remaining balls by means of a spacer rod as stated in the characterizing part of claim 6.

Preferably, the guide rail includes an elongated housing, and means 30 for the rotatable housing of the housing in the holding means. A portion of the exterior wall of the housing is adapted to the running track and has two spaced parallel parallel runs, extending along the longitudinal direction of the guide rail, which together with corresponding running surfaces of the running track provide roller guide tracks as explained above.

5 The guide rail is pivotally mounted in retaining means, which are motionless attached to the frame. Preferably, two retaining means are provided which are secured close to the end of the edge of the frame along which the frame may be displaced. For example, the retaining means may consist of hinges with an annular sliding bearing for accommodating a shaft.

According to the first embodiment, the guide rail for the automatic opening of the window can rotate at an angle with respect to the shaft, while · the rotation of the shaft relative to the holding means is simultaneously blocked. In addition, if a further opening of the window 15 and thus a further swing of the guide rail is to occur, the shaft is then pivoted relative to the holding means while the rotation of the guide rail about the shaft is prevented.

In the alternative embodiment, the inverted structure can also be provided, that is, the guide rail for the starting automatic opening of the window is held on the shaft and both can rotate at an angle relative to the holding means; to the., continued opening then the guide rail can rotate relative to the shaft, while at the same time the rotation of the shaft relative to the holding means is stopped.

25

The force for the automatic opening of the window is generated by a pre-tensioned screw spring arranged in the guide rail housing. The coil spring is passed around the shaft and with one end firmly connected to the shaft and with the other end either secured to the guide rail 30 or to the retaining means.

Even after the automatic opening of the window with the foreseen piece, the coil spring is still under bias. With reference to the first alternative mentioned above, in which the guide rail 35 during the automatic opening revolves around the shaft, while the shaft does not rotate in relation to the holding means, it is therefore necessary, after the desired opening width has been reached, to prevent further rotation of the shaft. the guide rail about the shaft. Preferably, there is provided for this a guide passage through the shaft and from this radially projecting bolt according to the characterizing part of claim 3, which can abut two remuneration formed in the interior of the guide rail housing. The distance between these two remunerations, as stated in the characterizing part of claim 4, determines the degree of rotation of the guide rail caused by the screw spring about the shaft fixed relative to the holding member. The rotation of the shaft relative to the holding means can be blocked by a clamping pin which projects parallel to the shaft from the holding member. At the spring force of the screw spring, the stop bolt passing through the shaft abuts against this clamping pin. Details of these devices will be apparent from the following detailed description of a preferred embodiment.

The degree of automatic opening 15 of the window caused by the screw spring can be freely predetermined. In practice, aperture widths of 25 to 40 °, for example, aperture angles of 25, 30, 35 or 40 ° have proved to be suitable. In accordance with the present invention, an aperture angle of 35 ° is particularly preferred, thereby ensuring a particularly good venting, and, in spite of this, the undesirable penetration of rain, snow and / or dust under the usual conditions is largely excluded by open window.

In order to retain the roof window with smaller opening angles as required, according to a preferred embodiment of the present invention 25, a protruding plate segment is fixedly fixed on which the stop or engagement points are formed on both sides, cf. the characteristic part of the Claim 8 stated. These stopping or engaging stages may consist of depressions in a relatively thick plate, on the other hand, there may be provided on a relatively thin plate, interspersed sections, between the stops or engaging; the locations are formed. The paired stop or engagement locations on the two sides of the plate segment may lie exactly opposite each other or be positioned offset in relation to each other. Opposite to the plate segment, as stated in the characterizing part of claim 8, a U-shaped clamping bracket is fixedly fixed to the frame, so that the plate segment is arranged between the two free branches of the clamping bracket, and at the end of each branch there is rotatably mounted a roller which may intervene in the stop or interlock 7 IS1349 locations. Thanks to the spring force of the clamping bracket, the rollers are pressed into the stop or engagement locations and ensure an effective holding of the window in the selected position. Preferably, three pairs of associated stop or engagement locations are provided, the outermost 5 corresponding to an opening of the window of approx. 35 ° f, as defined in the characterizing part of claim 9.

The degree of lateral displacement of the frame relative to the frame is determined by the length of the guide rail and the length of the guide rail. In the usual embodiment of the skylight of the present invention, the guide rail and the running rail have mutually matching lengths and this length corresponds to the length of the frame edge about which the frame can be pivoted; that is, the end stop of the guide and running rails flush with the two longitudinal edges of the frame if the frame can be pivoted about its upper edge.

In this case, the degree of frame coverage required with the frame's light opening next to the maximum displaced window of the seam results in the length of the spacer bar plus the diameter of all balls in a roller guide path. This contribution for the required cover generally lies between 1/3 and 1/4 of the light opening of the frame.

In a particular embodiment of the skylight of the present invention, a greater degree of lateral displacement is ensured at no significant additional cost. This embodiment is particularly advantageous for relatively narrow skylights which should also be used as an exit to the roof as needed. Also in this embodiment, the running rail and guide rail have the same length. However, this length is greater than the length of the frame edge along which the frame can be displaced, cf. the characterizing part of claim 7. If the running and guide rails on both sides extend the same piece to the side over the two longitudinal edges of the frame, the maximum lateral displacement is twice that of the piece than in the above-mentioned embodiment. Thus, without reducing the stability of the skylight or the ease with which the lateral displacement can take place, the degree of lateral displacement can be readily adapted to the existing requirements, in the extreme case the frame can be pushed completely out of the frame, thus that the entire light opening of the frame is available to go up on the roof and similar purposes.

In order to close the frame on the frame, it is desirable that the frame is arranged in advance so that it aligns exactly with the frame, so that the existing sealing profiles are not damaged when the frame is lowered. In order to ensure an exact flushing of the frame in relation to the frame, in accordance with the characterizing part of claim 10, a stop element is fixed which can engage a suitable stop or engagement point on the running rail. Eg. For example, the stop or engagement member may consist of a resiliently held roller which can engage a corresponding recess of 10 running rails. In this connection, the design of the roller, the inclination of the recess and / or the spring force with which the roller is pressed, is selected so that easy release of the stop or engagement element connection is possible, so that a displacement of the lateral rail is not significantly hindered after the window. opening. J.5

The invention is further explained with reference to the drawing, in which a preferred embodiment of the present skylight is shown.

In the drawing: FIG. 1 shows a skylight according to the present invention mounted on an inclined roof; FIG. 2 is a longitudinal section through a guide rail and a running rail for the skylight of the present invention; FIG. 3 is a cross section through guide rail and running rail. with adjacent structural parts; FIG. 4a and 4b are two views of a holding member; FIG. 5 schematically shows a section through a ball with associated running surfaces; FIG. 6a, 6b and 6c detail the retaining engagement; 7a and 7b are different embodiments of the skylight at maximum lateral displacement of the frame.

In FIG. 1 is a schematic view of a skylight according to the present invention inserted into a conventional sloping roof. To this skylight is a frame 1 and a frame 2 enclosing the window 3 to cover the light opening of the frame 1. On the frame 2 there is fixedly a running rail 4 which encloses a guide rail 5 and can be displaced along it. The guide rail 5 is pivotally attached to the frame 1. over the holding means 7 (of which only one can be seen). In the illustrated embodiment, the frame 2 is displaced along the common edge 11 with respect to the frame 1 and furthermore turned upwards to a vent position.

10 In FIG. 2 and 3, the devices for lateral displacement and oscillation of the frame relative to the frame are shown in detail. These devices essentially comprise the guide rail 5 with a coil spring 58 and a shaft 57, the running rail 4 and the holding means 7. The running rail 4 is fixed via a cavity profile 41 to the frame 2, which by means of a seal 21 retains the window 3. The running rail 4 is substantially C-shaped and partially encloses the guide rail 5. In the two short projecting branches 42 and 43, running surfaces 44 and 45 are recessed; along with corresponding tread surfaces 51 and 52. on guide rail 5 there are formed by 20 roller guide tracks for balls. Via these spheres 9, the running rail 4 is kept away from the guide rail 5, so that the running rail 4 on the one hand participates in the turns of the guide rail 5 and on the other hand can easily be displaced along the guide rail 5. Further details of the roller guide tracks are described in more detail below with reference to FIG. . 5th

The guide rail 5 consists essentially of a closed housing 53; On the inner wall of the housing 53 are provided 54, 55, 56. In the housing 53 a shaft 57 and a screw spring 58 are arranged. The screw spring 58, with its cantilevered end 59, rests against the consideration 56; the other end 60 of the coil spring 58 is secured to the shaft 57 by means of a retaining bolt 61.

30

The guide rail 5r's bearing on the shaft 57 and the shaft 57's bearing in the holding means 7 and 7 ', respectively, are shown in detail in FIG. 2. The same holding means 7 and 7 '(see also Figures 4a and 4b) are fixedly fixed in the two end portions of the edge 11 of the frame 1. For fastening, e.g.

35 screws 71 which are screwed into the frame 1. On the retaining means 7 a circular bore 72 is provided which serves as a bearing for the shaft 57. A distance from the bore 72 is provided a tensioning pin 73, which is perpendicular from 151349. the holding member 7, which serves as a consideration for the impact bolt 62. The impact bolt .62 is passed through the shaft 57 in the two end sections and extends with its protruding section 63 beyond the circumference of the shaft 57f. With this protruding section 63, the stop bolt 62 lies partly 5 against the clamping pin 73 ', thereby supporting the rotational force of the screw spring 58 with respect to the holding means 7; as a result, it is prevented that the shaft 57 can rotate relative to the holding means 7 in the pulling direction of the spring 58. In addition, the impact bolt 62, with its protruding section 63, abuts one of the two recesses 54 or 55 on the inner wall of the housing 53. As a result, the degree of rotation of the guide rail 5 is determined in relation to the shaft 57. In the illustrated embodiment, the distance between the remuneration 54 and 55 ensures a rotation of the guide rail 5 relative to the shaft 57 of approx. 35 °; if the section 63 abuts the consideration 54, the frame 2 also abuts the frame 1 and the window 15 is closed (position A). If, on the other hand, section 63 abuts the consideration 55, the frame is 2. with the pane 3 in the dashed line position B, which corresponds to the maximum opening width after the automatic opening of the window. 1 2 3 4 5 6 7 8 9 10 11

In order to reach the position C shown in the dotted line corresponding to 2 to the fully opened window, the guide rail 5 and the shaft 57 3 must also be rotated together relative to the holding member 7; As can be seen, for this purpose only 4 shaft 57 is rotated in bearings 72, while section 63 5 is still abut against recessed 55, so that rotation of the guide rail relative to shaft 57 is prevented. At the return of the window 7 from position C to position B, the stop bolt 62 stands 8 with its protruding section 63 against the remuneration 55, including cure.

9 The frictional resistance in bearings 72 must be overcome. First, by pivoting 10 of the window out of position B to A, section 63 frees itself from the weather 11 and finally re-occupies the position up to consideration 54.

11 151349

As seen in FIG. 2, slide bearings 64 are provided which, with their inner circumference slidingly abut against the shaft 57> and with their outer circumference, are fixed on the inner wall of the housing 53 of the guide rail 5; hereby the pivotal bearing of the guide rail 5 is secured relative to the shaft 5. 2 the placement of balls 9 and a spacer rod 91 within a roller guide track formed by the running surfaces on one side of the guide rail and on the other side of the running rail 4. On both ends, the roller guide track is limited on one side by end stops 65 and 66 of the guide rail. 5 and, on the other hand, at one-10 end stops 46 and 47 on the guide rail 4. Thus, at the maximum lateral displacement of the running rail 4 relative to the guide rail 5, the balls 9 'abut against the end stop 66 and the balls 9 against the end stop 46 and the balls respectively. 9 against the end stop 65 and the balls 9 'against the end stop 47.

In FIG. 5 schematically shows the placement of a ball 9 in a roller guide track. As shown, the running surfaces, namely the running surfaces 51 (52, respectively) on the guide 53 of the guide rail 5, as well as the running surface 44 (respectively 46) of the running rail, almost completely enclose the ball 9. For manufacturing reasons, the running surfaces differ slightly from a circular cross-section with the purpose of the ball 9 abutting the end regions of each running surface 44 and 51. As a result, a so-called 4-point bearing is obtained, which together with a maximum distance between the two roller guide tracks ensures precise control of the running rail 4 on the guide rail 5. In this embodiment, no control of the balls 9 or 9 * is provided by means of a ball holder; the omission of the ball carrier permits a longitudinal enclosure of the balls 9 by means of the running surfaces 44 and 51, respectively, and a greater distance between the roller guide tracks. In the practical testing of the roof window of the present invention, it has been found that thanks to these precautions, even with larger windows of appreciable weight, a slight displacement along a single guide rail is ensured at the same time as a swingability of this guide rail. 1 in FIG. 6a, 6b and 6c there is shown a restraint by which the opened skylight can be permanently retained in a particular position. To this restraint 8 is a plate segment 80 which is perpendicular to the outer wall 53 of the guide rail 5. In this embodiment, the plate segment 80 consists of a thicker plastic plate along which circumferential or engaging locations · 81, 81 'and 81 ", these stop locations 81 are recessed on both sides of the plastic plate 80. Furthermore, by means of a (not shown) clamping plate, a spring bracket · 52 is fixedly fixed to the frame 1. The free branches 83 and 84 of the spring bracket 82 are angled and carry rollers 85 5 and 86, which can be rotated about the branches 83 and 84, respectively. The rollers 85 and 86, respectively, can engage the opposite stop locations 81 of the plate segment 80 and, thanks to the spring force of the spring bracket 82, depress the springs into these stop points. open window also when the window has a substantial weight of 10. In the spring shackles shown in Figures 6b and 6c, the branches 83 and 84 differ in their length, if also the stop locations 81 on the plate segment 80's opposite sides are displaced in a corresponding manner, this allows rollers 85 and 86 to engage even better at stop points 81.

15

Brought as shown in FIG. 6a the rollers 85 engage the stop points 81, then the skylight is maintained at an aperture angle of approx. 35 °, which in this embodiment corresponds to the maximum opening angle of the automatic opening. A retaining of the rollers 85 at the stop locations 20 81 'corresponds to an opening of the window of approx. 20 °; similarly, retaining the rollers 85 in the stop locations 81 "corresponds to an opening of the window of about 7 °.

In FIG. Figures 7a and 7b show schematically the maximum displacement of frame 2 in relation to frame 1 in various embodiments of the skylight of the present invention. In the embodiment shown in FIG. 7a, the running rail 5, which is pivotally attached to the frame 1 by means of the holding means 7, and the running rail 4 fixed on the frame 2 are substantially the same length. This length corresponds to the length 30 of the edge 11 of the frame 1 along which the frame can be displaced.

As shown, under these conditions, the maximum displacement of the frame 2 is relative to the frame 1 in the case where the balls 9 abut the end stop 46 of the running rail 4 and the balls 95 abut the end stop 66 on the guide rail 5, thereby between the two balls. further balls and the spacer rod 91 are disposed.

As can be seen from a comparison of FIG. 7a and 7b, the degree of lateral displacement can be easily increased by increasing the length of the guide rail 5 and the running rail 4 relative to the length of the edge 11 along which the frame is displaced. According to this in FIG. 7b
