Guide rail arrangement for a post-and-beam facade, post-and-beam facade equipped with such guide rail arrangements

Description

[0001] The invention relates to a guide rail arrangement for sun protection systems such as vertical awnings or external venetian blinds, for mounting on a post of a post-and-beam facade, in which threaded bolts projecting vertically along the post are anchored at intervals and which preferably has a cover shell pressed onto the outside of the building.

[0002] After a long time when only sun protection systems with fixed curtains, such as rotatable louvers, were used on post-and-beam facades, over time guide rails specifically designed for post-and-beam facades for movable sun protection curtains were developed, so that today sun protection systems with movable curtains are also installed on post-and-beam facades.

[0003] German patent DE 103 06 732 B4 describes a double guide rail, formed in one piece with a cover plate that can be pressed onto a post of a post-and-beam facade, for two guide carriages equipped with wheels for two awning fabrics arranged side by side. However, this arrangement has the disadvantage that all forces acting on the guide rail are transferred into the cover plate, which is merely pressed on. Furthermore, cover plates without guide rails are conventionally already attached to the post-and-beam facade during construction.

[0004] Another guide rail arrangement for attachment to a post-and-beam facade is described in German patent DE 10 2010 052 365 B4. This arrangement features a base profile that is screwed to the facade post and supports two guide rail profiles, each with a guide groove that corresponds to one of two adjacent sunshade panels. The base profile is attached to the post with screws that are inserted into pre-drilled threaded holes in the post. This means that the base profile bears force against the post's top surface, which can lead to damage to the facade due to wind loads and similar factors acting on the sunshade panels.

[0005] German patent application DE 10 2006 004 493 A1 describes a facade post with a cover profile onto which adapters or holders are mounted and screwed to it using nuts. The holders have elongated holes on their sides, to which a base profile supporting a guide rail profile is attached by means of fastening screws inserted into the elongated holes of the holders from the side.

[0006] Similarly, German patent application DE 10 2011 118 098 A1 shows holders provided for fastening the guide rail of a sun protection system to a facade, wherein the holders have two elongated holes for fastening them with two threaded bolts.

[0007] In many cases, post-and-beam facades already have vertically protruding threaded bolts at intervals along the post, which are anchored in the post and serve to mount additional elements.

[0008] It is therefore an object of the present invention to create a guide rail arrangement suitable for mounting on a post of a post-and-beam facade, in which threaded bolts projecting vertically along the post are already anchored in the post at intervals, wherein the guide rail arrangement allows a force-based decoupling of the guide rail arrangement from the outwardly facing surface of the post, i.e., usually a pressed-on cover shell.

[0009] This problem is solved using the features of claim 1.

[0010] According to the invention, the guide rail arrangement has a plurality of holders, each of which has an inner side facing the post, on which an internal thread matching one of the threaded bolts of the post or a corresponding through hole opens, so that the respective holder can be screwed directly and / or by means of a number of nuts onto one of the threaded bolts.Furthermore, the guide rail arrangement comprises a base profile that can be attached to the screwed-on brackets and which carries at least one, preferably two, adjacent guide grooves. These grooves serve for the lateral guidance of a retractable sunshade, preferably for the lateral guidance of two adjacent retractable sunshades, such as awning fabrics or Venetian blinds, or for the lateral guidance of one or two adjacent end profiles to which the lower end of the respective sunshade is attached. A fastening device is provided for securing the base profile, which is attached to the brackets, to the brackets.

[0011] The fastening device has a snap-fit ​​connection between the base profile and at least one, preferably each, of the holders for attaching the base profile to the brackets. Alternatively or additionally, the fastening device can also include a clamping connection between the base profile and at least one, preferably each, of the holders. For the final fastening of the base profile to the holders, a screw connection between the base profile and at least one, preferably each, of the holders is provided, or a rivet connection between the base profile and at least one, preferably each, of the holders, in particular with a number of rivets applied from at least one side facing one of the sunshade panels.

[0012] Because the majority of brackets are positioned between the base profile and the post of the post-and-beam facade, and these brackets can be screwed to the post while simultaneously being secured against further rotation by the base profile, a rigid screw connection between the brackets and the post, which would transmit compressive and tensile forces, is unnecessary. This prevents the transmission of unwanted compressive or tensile forces—such as those caused by gusts of wind—into the post, and especially into its pressed-on cover plate, and back into the guide rail assembly via the threaded bolts, without compromising the stability of the guide rail assembly's attachment to the post. Furthermore, the brackets can be individually positioned relative to the facade, allowing for tolerance compensation, for example, if the outside of the post is not perfectly vertical.

[0013] These advantages are particularly evident in a post-and-beam facade which has posts with threaded bolts anchored at intervals along the post and projecting vertically outwards, as well as preferably cover plates pressed onto the exterior of the building and penetrated by the threaded bolts, wherein at least two of the posts each have one of the guide rail assemblies according to the invention mounted on them. This allows the guide rail assemblies to be mounted at a distance from the facade or the post, especially its cover plate, or at least only in contact with the post or cover plate without applying pressure, thus preventing the undesired force transmission between the guide rail assembly and the post or cover plate.

[0014] A method for mounting the guide rail arrangement according to the invention on a post of such a post-and-beam facade accordingly comprises the following steps: screwing each of the plurality of holders to one of the threaded bolts at a distance from the post, in particular from its cover plate or at least only with pressure-free contact with the post or its cover plate, attaching the base profile to the holders and fastening the base profile to the holders.

[0015] Instead of using the bracket's internal thread, which corresponds to the post's threaded bolt, and thus screwing the bracket onto the bolt, the bracket can also be attached to the threaded bolt using two nuts. In this case, the bracket can have a through hole instead of an internal thread, allowing the bracket to be simply slipped onto the threaded bolt after screwing on the first nut and then secured with a second nut. The distance between the bracket and the post or cover plate can then be adjusted using the first nut.

[0016] Advantageously, the base profile is attached to the brackets by locking it into place via a snap-fit ​​connection between the brackets and the base profile, and / or by clamping it via a clamping connection between the brackets and the base profile. This pre-fixes the base profile to the brackets before it is adjusted longitudinally and then screwed to the brackets. This significantly simplifies assembly because there is no risk of the base profile falling off when adjusting its longitudinal position on the brackets, i.e., when sliding the attached base profile on the brackets.

[0017] If the base profile has a longitudinal groove facing the brackets, and each bracket has a support projection facing the longitudinal groove, extending in the longitudinal direction of the base profile and fitting into the longitudinal groove, so that the base profile can be slid onto the support projections of the brackets, then attaching the base profile to the brackets can be done intuitively and correctly by simply sliding the base profile, with its longitudinal groove, onto the support projections of the brackets. At the same time, the necessary sliding capacity or degree of freedom for adjusting the position in the longitudinal direction of the post is maintained. Furthermore, the snap-fit ​​connection of the base profile to the brackets, or the clamping connection of the base profile to the brackets, can be easily released in this way by utilizing two side legs of the base profile flanking the longitudinal groove.

[0018] The snap-fit ​​connection can thus comprise two snap-fit ​​lugs, each projecting towards the support projections of the holders on one of the two side legs flanking the longitudinal groove. Each support projection has an undercut on each of its two sides facing the side legs, facing the snap-fit ​​lugs there, so that the base profile can be snap-fitted to the holders. The clamping connection, on the other hand, could be achieved by clamping the support projections of the holders between the two side legs of the base profile flanking the longitudinal groove of the base profile.

[0019] The screw connection of the base profile to the holders can be made using a number of screws, in order to minimize visual impairment of the appearance of the guide rail arrangement, such that the screws are screwed into the base profile from at least one side facing one of the sun protection curtains, i.e. advantageously into one or both side legs flanking the longitudinal groove and from there further into the support projections of the holders or at least against the support projections of the holders.

[0020] If the screws connecting the base profile and the brackets are designed as self-drilling screws, this allows for flexible positioning without the need for through holes in the base profile and threaded holes in the respective brackets that would have to align when positioning the base profile on the brackets. Alternatively, elongated holes in the base profile and / or screw channels along the brackets would also be conceivable. It is particularly advantageous if the screws are inserted into the base profile from at least one side facing one of the sunshade panels, as they are least likely to disrupt the appearance of the guide rail arrangement at this point.

[0021] Furthermore, the use of additional guide groove profiles, supported by the base profile, allows for complete concealment of the screws connecting the base profile and the bracket. The foot section of each bracket, adjoining the support projection on the post side, and thus the brackets as a whole, can also be concealed by appropriately designing the guide groove profiles. This results in a seamless appearance while still allowing access to all screws necessary for disassembly when the guide groove profile(s) are removed. A guide groove profile can be attached to the base profile if the guide rail arrangement is intended solely for guiding a single curtain or blind.If, on the other hand, two curtains arranged side by side are to be guided laterally on the guide rail assembly, the base profile can support two preferably identical guide groove profiles, each with a guide groove opening towards the respective curtain on both sides. Alternatively, it would be conceivable to provide a single guide groove profile with both guide grooves, which would then be attached to the base profile as a whole.

[0022] To attach the guide rail profiles to the base profile, a number of screw bolts, which can be advantageously screwed in from the side, can be used. Advantageously, the base profile has a screw channel on each of its sides facing the two sunshade panels, into which the screw bolts intended for connecting the respective guide groove profile can be screwed.

[0023] If the base profile also has a number of hook strips opening towards the outside of the building for each guide groove profile, into which the respective guide groove profile can be inserted with its webs facing the facade and resting against the side wall sections of the base profile, then the guide groove profile can be clamped against the hook strips of the base profile by screwing the screw bolts into the screw channel and still be easily mounted to the base profile. The base profile can have a stop for each guide groove profile against which the guide groove profile comes to rest when the webs are inserted into the hook strips, without reaching the post, and especially without its cover plate, thus ensuring correct positioning in the normal direction to the post.

[0024] If the screw connection between the base profile and the brackets uses self-drilling screws instead of conventional screws and corresponding threaded holes, which are inserted into the base profile (preferably made of aluminum) from the side, then a V-shaped centering channel can be formed along the base profile where the self-drilling screws are to be inserted, instead of a through hole. Such a centering channel can also be provided at a suitable location along the brackets, so that slight deviations in the position of the mounted base profile on the respective bracket result in a certain degree of positional correction when the self-drilling screw is inserted.

[0025] If each bracket has at least one stop for the base profile, preferably one on each side of the respective threaded bolt, against which the base profile comes to rest with a counter-stop when attached to the brackets, without reaching the post or its cover plate, then, firstly, the position of the base profile to the brackets in the normal direction to the post can be precisely adjusted simply by attaching the brackets, and secondly, it can be ensured that the base profile does not press against the post or its cover plate.

[0026] The base profile can have a cover wall projecting outwards on both sides of the building exterior, which covers the two guide groove profiles on the building exterior, or, in the case of only one guide groove provided on the guide rail assembly and thus only one guide groove profile attached to the base profile, a cover wall projecting beyond the guide groove profile on the building exterior and extending along the side wall facing away from the guide groove profile to the post. For greater uniformity, it would also be conceivable to have a base profile for both guide rail assembly with two guide grooves or two guide groove profiles and for use with only one guide groove or two guide groove profiles, instead of a closed side wall.to use only one guide groove profile and then, if only one guide groove is to be provided, to cover the available installation space for a second guide groove profile with a corresponding cover profile.

[0027] Further advantageous embodiments of the invention will be explained in more detail with reference to the embodiments illustrated in the accompanying drawings. These show: Figure 1 shows a post of a post-and-beam facade, represented solely by its cover plate, with vertically projecting threaded bolts anchored in the post, with only one of the threaded bolts being shown; Figure 2 shows the in Fig. 1 The post shown has a holder for a guide rail arrangement screwed to the threaded bolt according to an embodiment of the invention; Figure 3 in Fig. 2 The illustrated post with the bracket screwed to the threaded bolt and a base profile of the guide rail assembly placed on and attached to the bracket; Figure 4den in Fig. 3 The post shown with holder and base profile attached thereto, as well as two guide groove profiles attached to the base profile, are shown in a top view; and Figure 5 shows a further embodiment of the guide rail arrangement according to the invention in one of the Fig. 4 corresponding top view.

[0028] First, reference is made to the Fig. 1 , which shows only its cover shell 1 as a representative of an entire post of a post-and-beam facade and only one threaded bolt 2 penetrating the cover shell as a representative of a row of vertically protruding threaded bolts anchored in the post extending along the post.

[0029] Again Fig. 2 As can be seen, the guide rail arrangement according to the invention has a plurality of holders 3, each of which is placed on one of the threaded bolts 2 and screwed in place. The holders 3, of which only one is shown here as an example, are identical in construction and each has a support projection designated 8, as well as a foot section 8a adjoining the support projection 8 on the post side. A centering groove 12a is also visible, which will be discussed further below.

[0030] After the brackets 3 have been screwed to the threaded bolts 2, a base profile 4 of the guide rail assembly is now to be placed onto the brackets 3 and fastened to them. Self-drilling screws 12 are used for this purpose, which are drilled or screwed into the base profile 4 from the side. A centering groove 12b extending along the base profile 4 serves to position the self-drilling screws 12 and, when the base profile 4 is correctly positioned, aligns with the respective centering groove 12a of the associated bracket 3, thus ensuring that the self-drilling screws 12 can be screwed into the aluminum profiles.

[0031] The base profile 4 has a longitudinal groove 6 flanked by two side legs 9,10, with which it engages the support projection 8 ( Fig. 2 The bracket 3 is mounted on the base rail 4. The brackets 3 can thus be screwed together from the sides facing the sunshade curtains through the side legs 9 and 10 using the support projection 8 of the brackets 3. Overall, the base rail 4 has an approximately T-shaped cross-section, with a building-side cover wall section 21 projecting outwards on both sides and side wall sections on the side legs 9 and 10 facing the sunshade curtains.

[0032] For hanging in Fig. 4 The guide groove profiles 7 shown, on which a guide groove 24 assigned to one of the sun protection curtains is formed, have hook strips 16,17 formed on the side wall sections of the base profile 4 facing sideways with openings towards the outside of the building, as well as two screw channels 26 that open to the side.

[0033] The Fig. 4 Figure 1 now shows the guide rail assembly in its fully assembled state, attached to the post. For this purpose, the two aforementioned guide groove profiles 7 are positioned on both sides of the base profile 4, against the side wall sections of the base profile 4, and then hooked into the open hook strips 16, 17 of the base profile 4 with their webs 18, 19 facing inwards. With side covers extending from the respective guide groove 24 to the post or the cover plate 1, the guide groove profiles 7 not only conceal the screw heads of the self-drilling screws 12, with which the base profile 4 is screwed to the brackets 3, but also the entire base section 8a of the brackets 3, resulting in a closed appearance of the guide rail assembly.The guide groove profiles are additionally hooked onto a hook strip 27 projecting towards the outside of the building at the distal end of the foot section 8a of the holders 3, using a hook strip 28 open towards the interior of the building. By screwing the guide groove profiles 7 to the screw channels 26 of the base profile 4 using screw bolts 22 (indicated in the figure only by dashed lines), the base profile 4 and the guide groove profiles 7 are tensioned in the area of ​​the hook strips 16, 17, 27, thus ensuring precise alignment of the guide groove profiles 7.

[0034] The Fig. 4 It can also be seen that the holders 3 have internal threads at 11a, with which they are screwed onto the associated threaded bolt 2 of the post. Furthermore, locking lugs 13 can be seen at the free ends of the two side legs 9, 10 of the base profile 4, with which the base profile 4 is snapped onto the holders 3 at associated undercuts 14. In addition, when the base profile 4 with its longitudinal groove 6 is slid onto the support projections 8 of the holders 3, a clamping connection 23 is formed in the areas designated 23 and marked with dashed circles between the side legs 9, 10 flanking the longitudinal groove 6 and the support projections 8 of the holders 3, because corresponding clamping lugs project from the side legs 9, 10 towards the support projections 8 in these areas.

[0035] The Fig. 5 Figure 1 shows an alternative embodiment of the guide rail arrangement with only one guide groove 24, for which, however, a guide groove profile 7 is required. Fig. 4 An identical guide groove profile 7 is attached to a base profile 44 with identical geometry on this side. On the opposite side, however, the base profile 44 is provided with a closed side wall cover, which has a hook strip 29 at its end facing the cover strip 1, opening towards the interior of the building, with which the base profile is supported on the hook strip 27 of the holder there.

[0036] Unlike holders 3 in the Fig. 4 In the embodiment shown here, however, the holder does not have internal threads, but rather through holes 11b, which are used to mount the threaded bolt 2 anchored in the post. To adjust the distance of the holder from the cover strip 1 and simultaneously screw the holder to the threaded bolt 2, two nuts 25a and 25b are provided. Before mounting the holder, the first nut 25a is screwed on, which defines the distance of the holder from the cover strip 1. To then fix the holder to the threaded bolt 2, the second nut 25b is screwed on, which can be done from above or below.

[0037] Analogous to the in Fig. 4 In the illustrated embodiment, the base profile 44 can be snapped onto the holder and clamped to it. For screw fastening, it is therefore sufficient to insert self-drilling screws 12 from the side accessible before attaching the guide groove profile 7.

[0038] Variations and modifications of the embodiments shown are possible without leaving the scope of the invention as defined by the attached claims.
