Description

The present invention relates to a mounting system for sun protection systems for inside mounting to window frames or glazing beads, at least consisting of two side beams, two lateral guide rails and two foot parts, wherein the guide rail is arranged and held between a side support and a foot part and the side support and the Foot parts with the inner surfaces of the window frame or the glazing beads are screwed.

Such fastening systems are used, for example, on skylights in order to guide the movement rail of a sunshade system, which is generally designed as a folding or Venetian blind, and to reduce a bulging of rail and fabric in particular with flat installation angles. The lateral incidence of light can be minimized by the guide rails.

In the known fastening systems, a problem is that they usually have to be specially adapted for each type of window frame or glazing beads, as for example at different angles of inclination of the inner surfaces of window frame or glazing beads usually no longer an attachment of the guide rails in one defined angular position to the glass is possible. In order to cover the wide range available on the market window frame or glazing beads, therefore, the manufacturers of sun protection systems must have a variety of different side support, foot parts and usually also guide rails ready to use their facilities on all windows.

The object of the present invention is to provide a fastening system that can be used universally and covers the usual inclination areas of the inner surfaces of the window frame or glazing beads.

According to the invention the object is achieved by a fastening system of the type described above, in which the side support convex bearing areas for resting on the inner surfaces of window frames or glazing beads and at least two mounting holes are provided at different positions of the convex curvature of the support areas.

The fastening system according to the invention provides for the bearing areas of the side support on the window frame usually no areal contact, but a line-shaped plant before, depending on the angle of inclination, a correspondingly different contact line of the bearing areas is used for investment. Depending on the tilting range to be covered, the convex contact area will be formed over a corresponding angular range.

In order to obtain a non-tilted hold of the side support on the window frame or the glass strip despite the only linear system, the at least two mounting holes are further provided at different positions of the convex curvature. Since with only one hole at a certain position the risk could exist that aligns when tightening a mounting screw of the side support according to the position of the screw in a wrong angular position, the solution of the invention provides mounting holes in the corresponding angular position, ie with the correct orientation of the side support can be a fixing screw always be screwed in vertical or nearly perpendicular orientation to the inclined inner surface, so that the side support undergoes no significant change in its orientation when tightening. In general, several degrees of inclination angles can be covered with a mounting hole, for example with a bore an angular range of 5 ° to 10 °, so that in a side support with a curvature region covering the angle of inclination of 90 ° to 115 °, as a rule three mounting holes are sufficient.

The fastening system according to the invention is even suitable if the window frame or the glazing beads in turn do not have plane contact surfaces, as well as the line-shaped system in conjunction with a selected for mounting, suitable bore ensures a tilt-free grip.

In a preferred embodiment of the invention it is provided that a plurality of closely spaced longitudinal ribs are provided in the contact areas.

Due to the longitudinal ribs whose height may be a fraction of a millimeter, with a corresponding effect can also be achieved with longitudinal grooves corresponding deep between the ribs, an investment in the window frame or the glass strip by two adjacent ribs instead, so that an improved grip against tilting results. The distance between such longitudinal ribs may be less than 1 mm in order to have two adjacent ribs as an attachment for narrow angular ranges.

In a further preferred embodiment of the invention it is provided that at the top of the side support In addition to the support areas angled, flat stop surfaces are to rest on a flat top of the window frame or the glass strip. The planar abutment surfaces facilitate the alignment of the side support to the window frame or the glass strip, so that the risk of mounting with incorrect inclination position is reduced. The orientation of the side support to the window frame or the glass strip is then exactly defined by the planar support of the stop surface on the top and the linear contact of the convex curvature or the spaced longitudinal ribs on the window frame or the glass strip.

Since in practice the maximum angle of inclination of the window frame or the glazing beads is limited, the invention is provided in a preferred embodiment that adjoin the abutment surface opposite side of the convex bearing areas substantially ebenflächige support surfaces to the abutment surfaces in a certain angle which corresponds to the maximum angle of inclination of a window frame or a glass strip, under which the fastening system can be mounted.

When mounting on such a window frame, then the support surface sets flat against the frame and it can be provided a corresponding mounting hole for this installation case. However, the surface contact is important only in the limiting case of the maximum angle of inclination, since otherwise the convex contact area between the abutment surfaces and these support surfaces is used.

In a particularly preferred embodiment of the invention, the side support for further contact with the glazing beads or window frame at least one removable projection, wherein the tangent between such The projections define an additional point-like support in addition to the line-shaped systems and are usually formed in the region of the planar support surface. When mounting at a maximum angle of inclination will remove all removable protrusions before mounting, while at the smallest inclination angle, usually the 90 ° variant with perpendicular to the glass pane inside edge of the window frame or the glass strip, no projection must be removed. For intermediate dimensions then the longer projections can be removed. The projections facilitate alignment of the side supports during assembly and may replace the stop surfaces, but preferably are used in combination therewith. The projections in turn each cover a certain angle range.

To determine the guide rails on the side supports these preferably have retaining pins on which the guide rails can be plugged in a certain angular position. After the previously made alignment of the side support with respect to the window frame or the glass strip takes the guide rail accordingly when plugging through the retaining pins the desired angular position.

In order to achieve a particularly good play-free hold, it is provided in a preferred development that in each case a plurality of retaining pins are provided which comprise a profile wall of the respective guide rail on both sides. Particularly preferred is such a resilient design of at least one pin per side support that this presses the profile wall of the inserted guide rail against the remaining pin. In addition to the already mentioned Backlash is also achieved by the resilient pin and the possibility to adjust the guide rail by taking advantage of the elasticity inclined and align during insertion into the pin parallel to the glass. Significantly easier thereby is the mounting of a guide rail, in the foot already a foot part is used, which should rest as far as possible without play at the bottom of the window frame or on a lower glass bar.

In order to determine the mounting system on the frame or the glass strip before mounting the actual sunshade system, is provided in a further embodiment of the invention that the side members each have a recess through which a movement rail and a curtain of a sunshade system to be mounted, in usually folding gates, folding or Venetian blinds, in the assembled state of the guide rails are inserted into this.

For the final installation of the upper rail of the sun protection systems, the side supports preferably each have a hook, under which in the mounted state of the side support an upper rail is pivoted and prevents the upper rail from falling out. The upper rail can be secured by additional fasteners, with this pivoting solution is already given by the pull on the upper rail curtain alone by the hook a secure hold even in very flat inclined systems.

In order to prevent axial displacement of the upper rail in the side rails, which could lead to damage to the curtain and / or lateral tension cords possess the side supports preferably each have an axial stop for supporting the inserted upper rail.

A still further embodiment of the invention provides a fastening system with a diaphragm, which can be latched with locking elements on the two side supports. The cover covers the mounting opening for the sun protection system and also covers the window frame or the glass strip, in order to prevent the passage of light there. Preferably, the locking elements each have an undercut and a spring element which is resiliently movable in the direction of the undercut, so that a secure hold of the aperture is given, but this can be easily mounted and removed for inspection purposes.

With respect to the guide rails and the foot parts, it is advantageous if they each have a support region whose curvature is carried out in accordance with the support surface of the side support. In this way, the linear system continues over the entire length of the guide rail. A design of the support ribs in the region of the guide rails and the foot parts is possible, but not necessary. Since the guide parts have abutment surfaces for placement on the end faces of the window frame or the glazing beads both in the region of a lateral profile and the lower profile and according to a three-point bearing is given during assembly, it is not absolutely necessary for the foot, a plurality of mounting holes for a provide the angle of inclination appropriate screw. But the foot parts may have in addition to the convex bearing areas a plurality of removable stop pins, which are each adapted to a certain angular range of the glass strip or the window frame.

Accordingly, any protruding stop pins are removed before assembly.

Since in window frames with inclined inner edges and the upper and lower profiles are usually inclined, the foot parts at their foot ends and the side support at their head ends preferably each have a convex contour corresponding to the convex bearing areas curved and the inside abutment on a head profile or Foot profile of the window frame are determined.

Fig. 1 shows an oblique view of a fastening system 1 according to the prior art for a sun protection system 2, which is designed here as a folding gate system with a moving rail 3. The fastening system 1 consists essentially of two lateral side beams 4, which are to be mounted on the inside of the upper flanks of a window frame, in the side support 4 inserted guide rails 5 and the guide rails 5 down final foot parts 6. The foot parts 6 are also used for anchoring of instep - / guide lines. The problem with these systems are different inclinations of the inner edges of the window frame or glazing beads to which the system is to be attached. For adaptation there are different profile shapes of the guide rails for different angles of inclination, wherein in Fig. 1a is a profile shape for a 90 ° inclination, in Fig. 1c a profile shape 5c for a maximum inclination of the inner edges and in Fig. 1b, an intermediate size of a guide rail 5b is shown , In addition, are often also specially adapted side support 4 and 6 foot parts required or it must be kept ready for the respective angle of inclination a variety of spacers.

In Fig. 2, an inventive side support 10 is shown, which is usually formed as a plastic part. The side support 10 has a convex support portion 12, which is traversed in the longitudinal direction with respect to the guide rail with a series of grooves 14, between which support ribs 16 are formed. At the top of the side support 10, a substantially planar stop surface 18 adjoins the convex support region 12, the limit angle between the support region 12 and the stop surface 18 being 90 °. The planar abutment surface 18 serves to rest on the end face of a window frame or a glazing bead, while the convex support region 12 is provided for bearing against the inclined inner flank of the frame or glazing bead. In a 90 ° embodiment, the area of the bearing ribs 16 facing the abutment surface 16 abuts against the inner flank, while, depending on the inclination, in a transition region up to a maximum angle, two adjoining support ribs 16 of the convex bearing region lying farther away from the abutment surface 18 are, which create a line on the inclined inner edge. Between the support area 12 and the abutment surface 18, a recessed area 20 is provided in order to ensure a linear contact in the support area 12 at 90 ° inclination. The maximum angle of inclination, under which the side support shown in FIG. 2 can be fixed to a window frame or a glass strip, is determined by the angle of inclination of a support surface adjoining the convex support region 12 opposite the recessed region 20 22, wherein the inclination angle of the support surface 22 with respect to the plane stop surface 18 corresponds to the maximum inclination angle, which may have a window frame or a glass strip, on which the side support 10 is mounted.

In the area of the support surface 22 removable projections in the form of two stop pins 24, 26 are provided in the illustrated embodiment, which are connected via breakable webs 28 to the side support 10. The longer stop pin 26 provides for a punctual additional support in the 90 ° mounting position, while the stop pin 24 is provided for an intermediate size and after the removal of the stop pin 26 can then apply to the inner edge of the window frame with appropriate inclination. At very large or maximum inclination angle both stop pins 24, 26 are removed. Further stop pins (see, for example, FIG. 9) can be provided to reduce the angular range to be covered by a stop pin.

In order to avoid a change in inclination of the side support 10 when tightening the mounting screws, different mounting holes 30, 32, 34 are provided for different angular ranges. A first mounting hole 30 extends into the recessed area 20 and is used for attachment to the inner edge of window frames with 90 ° inclination or only slightly larger angles of inclination. The second mounting hole is offset into the convex support portion 12 and covers an angular range of about 96 °, while a third mounting hole 32 is provided near the support surface 22 for angles about a tilt range of 102 °. At a critical angle, where appropriate, by removing the stop pin 26, 28 resulting breakthroughs are used for screwing in fastening screws. Finally, it should be noted that the mounting holes are all aligned so that the mounting screws can be screwed in an inclined orientation with respect to the glass so as to be easier to apply assembly tools.

In Fig. 3, the side support 10 is shown in a guide rail side view. Visible are three retaining pins 36, 38, 40, between each of which a gap 40 for a profile wall 42 (see FIG. 8) of the aufzusteckenden guide rail 43 is provided. The middle stop pin 36 has at its tip a spring tongue 41 which is elastically bendable on the one hand when attaching the guide rail and on the other hand, the profile wall 42 after plugging against the outer retaining pins 34, 38 presses and thus for a backlash-free, low-noise seat Guide rail 43 provides. In addition to the retaining pins 34, 36, 38, the side support 10 has a recess 46, whose function will be discussed later.

For the final assembly of a diaphragm 48 (see also Fig. 9), the side support 10 also has an undercut 50 and a spring element 52 spaced therefrom that is resilient in the direction of the undercut 50 and forms together with these locking elements for the diaphragm 48.

FIG. 4 shows the side support in a perspective view from a further angle and, together with FIG. 5, illustrates the support of an upper rail 54 (see FIG. 5) on the side support 10. The upper rail 54, which from the basic structure has a double T shaped cross-section with - deviating from the basic form - curved and profiled at the ends Has side walls, rests on a bottom surface 56 of the side member 10 and is prevented by a holder 58 which engages over the upper end of the rear side wall (see Fig. 5) from falling out. The insertion of the upper rail 54 is carried out in such a way that initially the upper side wall is inserted under the holder 58 and the upper rail 54 is then pivoted under the holder 58 until it rests on the bottom surface 56. In order to achieve an exact alignment of the upper rail 54 in the axial direction, an axial stop 60 is provided on which an end cap (not shown), which is inserted laterally into the upper rail 54, can be supported. The recess 46, which has already been referred to in Fig. 3, allows performing lateral tension cords (not shown).

Fig. 5 illustrates the positioning of the side member 10 with respect to the upper rail 54 and the guide rail 43 after assembly, wherein in Fig. 5, the profiles of a window frame or a glass bead have been omitted.

The mounting position of the side member 10 with respect to such a window frame 62 is illustrated in FIGS. 6 and 7. In Fig. 6, an inclined inner edge 64 of the head profile of the window frame is shown, wherein the inclination angle in the head region of the window frame usually corresponds to the inclination angle in the region of the side edges of the window frame. It can be seen in Fig. 6, that the side support in the head region has a convex contour 66, whose curvature substantially the support area 12 (see FIG. 2) and the support surface 22 corresponds. FIG. 6 shows a maximum angle of inclination, in which the abutment takes place in a region of the convex contour 66 which is designed in its angular position corresponding to the support surface 22. Shown FIG. 6 also shows the attachment of the diaphragm 48, wherein the fastening details, which will be discussed in more detail in connection with FIG. 9, have been omitted and merely intended to illustrate that the edge 68 of the upper frame profile is covered by the diaphragm 48 , so that there is no light incidence possible. Visible in Fig. 6 and resting on the side support 10 upper rail profile 54 and the guide rail 43 which is inserted into the retaining pin, not shown.

In the schematic view of FIG. 7, the abutment of the side member 10 is illustrated on a lateral profile 70 of a window frame with a right angle inclination. The stop surface 18 of the side support is, as with all inclination angles, flat on the outer surface of the frame profile, while on the inner edge of the side support 10 with its convex support portion 12 is linear. It can also be seen in FIG. 7 that the transition region 20 is recessed to achieve a defined abutment. The stop pins 24, 26 are not shown in Fig. 7, usually remains the longest stop pin of FIG. 2 at a 90 ° version of the frame profile 70, however, to obtain a secure three-point support.

In the already cited Fig. 8, the side support 10 is again shown with pivoted-upper rail and plugged guide rail 43 to illustrate the position of the central guide pin 36 with its spring projection 44 with respect to a profile wall 42 of the guide rail 43. The two outer retaining pins 34, 38 lie on the opposite side of the profile wall 42. Also clearly visible in Fig. 8 is the recess 46 for performing the tension cords of the sunshade system and insertion of the movement rail.

Finally, FIG. 9 shows a side carrier 10 which is plugged onto a guide rail 43 and is seen on the support region 12. The support ribs 16 formed by the incorporated grooves 14 are particularly well recognizable in the support region and the contour 66 at the head end of the side support. The attachment of the panel 48 by means of a first molded Profilvdrsprungs 86 which engages the undercut 50, and a second integrally formed on the panel 48 profile projection 88 which cooperates with the spring element 52 is also clearly visible. In contrast to the side carrier described above, the side support 10 has a further stop pin 25 for a finer resolution of the associated angle ranges.

10 shows a schematic sectional illustration of a guide rail 43 with a movement rail 72 guided therein, which has a guide pin 74 which is guided in a longitudinal chamber 76 of the guide rail 43. The guide rail 43 consists essentially of a diaphragm 78, of which a web with a convex abutment portion 80 leads away at right angles, which forms the longitudinal chamber 76 with a further web 82 which extends parallel to the aperture 78. At the web 82, finally, the roof-shaped profile wall 42 is formed, which is held on both sides by the retaining pins 34, 36, 38.

The position of the lateral inner flanks of a window frame with different angles of inclination is shown in FIGS. 10a to f. In Fig. 10a, a maximum inclination angle of 115 ° with respect to the glass surface is shown, with an investment of the guide rail 43 then takes place in the region of the free end 84 of the profile wall 42. In this case, the panel 78 covers the upper end of the inner flank in order to prevent light from entering. Steep angles of inclination of the inner flank are shown in the further figures, with FIG. 10f finally showing the rectangular orientation of the window frame. Especially with longer guide rails, it may be useful to provide suitable spacers in the region of the free end 84 of the rail 43 to ensure a tip-proof support of the rail even in the central region. This will be discussed later.

In the case of a foot part 90, as shown in FIG. 11, the support region is deviating from the side support 10. According to this, the foot part 90 also has a convex support region 92 with longitudinal ribs 94 and an adjoining support surface 96, the angle of inclination with respect to a stop surface 98 corresponds to the maximum inclination angle for which the described fastening system can be used. The foot part 90 also has 2 stop pins 100, which can be removed depending on the angle of inclination or remain on the foot part 90. Deviating from the side support 10, however, the foot part 90 shown in FIG. 11 has only one fastening bore 102, which is sufficient because the foot part 90, in addition to the lateral abutment surface 98 for resting on the upper side of a lateral frame profile of the window frame, also has a lower abutment surface 104 which rests against the surface of the lower frame profile of the window frame. As a result, a three-point bearing is provided so that no change in the inclination angle of the foot 90 itself can set more when tightening a screw in the bore 102 regardless of the inclination angle of the inner edge of the window frame. At the foot of the foot part 90, a convex abutment contour 106 can be seen, which in turn ensures a good contact with the inner edge of the lower frame profile. Shown is in the foot part 90 of FIG. 11 also has a hanger 108, in which a tension cord of the sunshade system can be suspended. The installation position of the foot part in a window frame can be seen in Fig. 12, wherein in addition to the position of the mounting hole 102 and the hanger eye 108 is particularly well recognized for the tensioning cord. Clearly visible is the overlap of the window frame by the lower stop surface 104, so that there again no light is to be feared. In Fig. 12, the moving rail 73 is also shown schematically.

For large system widths, it may be useful not to anchor a panel 48 or not only on the side members 10, but to provide alternative or additional holder 110, which are engaged in the upper rail profile.

The holders 110 may have different designs and are oriented in their exact shape after the profiling of the upper rail and provided on the diaphragm 48 holding elements 112. In the illustrated embodiment of the holder 110 sits a headband 114 in an undercut 116 of the upper rail, while at the blendenseitigen end a hammer head 118 engages an undercut groove 120 of the retaining elements 112, which may be formed by the profile projections 86, 88 (see FIG. 9).

In Fig. 14, finally, a spacer element 122 is still shown, which can be anchored with long guide rails 43 between the side support 10 and the foot part 90 between the convex abutment portion 80 and the free end 84 of the profile wall 42. The spacer element 122 has a contact surface 124 whose position is adapted to the convex abutment region 80 in accordance with the respective inclination angle. In the embodiment shown the spacer element 122 serves for support on a window frame, the inner edges of which have a right-angled inclination, wherein spacer elements are used in particular where a screw connection takes place and thereby a supplementary support to the glass strip is required.
