Fixing system for fixing a bracket for a sun protection system and sun protection system designed accordingly

Abstract

A fastening system serves to fix a bracket (12; 112) for a sun protection system (14) in relation to a guide rail (20) or another profile rail (136), wherein the bracket (12; 112) has a blade (16; 116) which is inserted into a profile cross-section (18; 118) of the guide rail (20) or of a vertical profile or other profile rail (136) connected thereto and is secured against pull-out by means of fastening means fixed therein.To facilitate easier assembly even under tolerances and to allow compensation for length changes, the fastening means are designed to engage in a recess (32) of the sword (16; 116) of the console (12; 112), with a degree of freedom of movement in the direction of an adjacent guide rail being provided between the fastening means and the recess (32), and the width of the sword (16; 116) being narrower in this direction than the profile cross-section (18; 118) into which the sword (16; 116) is inserted.

Description

[0001] According to the preamble of claim 1, the invention relates to a fastening system for securing a bracket for a sun protection system to a guide rail or other profile, wherein the bracket has a blade that is inserted into a profile cross-section of the guide rail or of a vertical profile or other profile connected thereto and is secured against pull-out by means of fastening means fixed therein. The present invention also relates to a sun protection system designed with such a fastening system and to a facade construction with such an integrated sun protection system.

[0002] EP 4 019 734 B1 shows a fastening arrangement of the type described above with a side bracket of a sun protection system which is fixed to a guide rail by means of a sword, wherein a threaded pin is screwed into the sword.

[0003] DE 10 2014 009 502 A1 shows a mounting of a console by means of a separate sword which is pressed into an insertion channel and screwed to the console.

[0004] DE 20 2017 006 481 U1 shows a console with a sword with several elongated holes, which has a cross-section adapted to the insertion channel and is screwed to the guide rail with fastening screws.

[0005] Conventional mounting systems involve rigidly screwing the sunshade system to the guide rails. This can lead to difficulties during installation or later operation because, firstly, thermal expansion due to temperature fluctuations, especially across the width of the system, cannot be compensated for, resulting in mechanical stress. Secondly, manufacturing tolerances during installation can only be corrected with considerable effort. Similarly, dimensional deviations occurring during installation can cause problems later on.

[0006] The object of the present invention is to avoid the aforementioned problems.

[0007] According to the invention, the problem is solved by a fastening system of the type mentioned at the outset, in which the fastening means engage in a recess of the sword of the console, wherein a degree of freedom of movement in the direction of an adjacent guide rail or other profile rail is provided between the fastening means and the horizontal opening, and the width of the sword in this direction is narrower than the profile cross-section into which the sword is inserted.

[0008] The solution according to the invention makes it possible to allow lateral displacement of the blade, at least in the area of ​​a console, so that the parts can move relative to each other. This has advantages because it allows tolerances, such as those resulting from manufacturing, assembly, or existing facades or Mauserwerk tolerances, to be compensated for, while during operation, thermal expansion across the width of the system can occur without stress. This is particularly advantageous for coupled systems. Coupled systems, also referred to as group systems, include both mechanically coupled systems, i.e., several systems operate via a common drive, and also series systems, in which the systems are mounted directly next to each other in a strip of panels, regardless of whether the panels are mounted on separate guide rails or on single-piece double guide rails.

[0009] The term "console" here refers to any type of connecting element that is either itself a supporting component of the sun protection system or is to be connected to a supporting component of the sun protection system. The console can also be formed by the side panel itself, so both terms are used interchangeably here.

[0010] Furthermore, the term "vertical profile" should be understood here to mean that it can also have an inclination relative to the vertical, for example, up to 10°. This also applies to the orientation of the guide rail. Such a case can occur with sloping facades or inclined sun protection systems.

[0011] In a preferred embodiment of the invention, the fastening means are provided to have a projection extending into the profile cross-section, which engages in a correspondingly inclined recess in the sword.

[0012] This design ensures the desired degree of freedom of movement while simultaneously guaranteeing easy assembly.

[0013] The projection can be formed, for example, by a horizontal leg of a mounting or securing angle, but inclined projections are also possible that engage in a correspondingly slanted recess in the sword.

[0014] A preferred embodiment of the fastening system provides that the horizontal leg of the mounting bracket protrudes through a slot in the front face or rear face of the profile cross-section of the guide rail or vertical profile, and a perpendicularly angled leg is connected to the guide rail or vertical profile, e.g., by screwing, gluing, or riveting. This principle can also be implemented with inclined projections / slots.

[0015] Alternatively, the fastening means can also engage in a suitably designed opening in the sword as a projection or in the form of a bolt from a lateral flank of the profile cross-section.

[0016] Using one of these designs, the mounting bracket or other fastening element can be mounted in a particularly simple manner after the sword has been inserted into the profile cross-section.

[0017] In the case of several interconnected systems, it is preferably provided that guide rails are provided on both sides of at least one profile cross-section. The sword can be assigned to a bracket that can serve as a bearing block for sun protection systems on both sides, whereby the winding shafts or other drive shafts of the sun protection systems can be rigidly coupled to each other in the area of ​​the bracket.

[0018] The present invention also relates to a sun protection system with a fastening system according to one of the preceding claims. In this system, at least two or more profile cross-sections are provided into which the brackets' arms are inserted, the fastening system according to one of the preceding claims being provided at at least one connection between an arm and a profile cross-section.

[0019] It is not necessary to arrange all the fins of a sunshade system—where this term also includes a group of several adjacent sunshade systems—with lateral play within their respective profile cross-sections. Such systems are also referred to as group systems or compound systems. It can also be advantageous for a fin to be inserted into a profile cross-section without play and secured in a suitable manner to form a fixed bearing.

[0020] In a preferred embodiment of the invention, the concept with a fixed bearing can also be used with at least two coupled shading curtains with intermediate guide rails.

[0021] The fixed bearing can be provided on any sword; in the case of several shades arranged side by side, preferably in a central area so that longitudinal expansions cannot add up over the entire width of the system.

[0022] However, adjacent systems can also be mounted independently of each other, whereby the drives can be coupled via a coupling that is movable in the longitudinal direction.

[0023] In principle, the solution according to the invention is suitable for sun protection systems of any kind, preferably for those which have winding elements for a curtain or lifting devices, wherein such a sun protection system is designed, for example, as a window awning, Venetian blind or roller shutter.

[0024] The solution according to the invention also covers, but is not limited to, a facade construction with a sun protection system of the type described above, attached to a post-and-beam construction or unitized facade. The solution according to the invention unfolds its advantages in a particular way when used in a facade construction, since the aforementioned dimensional deviations due to thermal expansion or manufacturing, assembly, or facade tolerances can be particularly critical in facade constructions.

[0025] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the exemplary embodiment described below with reference to the drawing. The drawing shows: Fig. 1 A side view of a sun protection system with a console inserted into a profile cross-section. Fig. 2 one opposite Fig. 1 slightly rotated view; Fig. 3 a top view of two adjacent consoles of neighboring sun protection systems inserted into a profile cross-section; Fig. 4 an oblique view of another embodiment of a safety angle.

[0026] In Fig. 1Figure 14 shows a side panel 12 of a sun protection system 14, clad with a cover 10, which is inserted into a profile cross-section 18 of a vertical guide rail 20 by means of a blade 16. The sun protection system can be a roller shutter, a Venetian blind, a window awning, or any other sun protection system suitable for outdoor use.

[0027] The sword 16 can be formed as a single unit with the side panel and a bracket, but configurations are also possible in which the sword is connected to the bracket as a separate component. Since the specific design is not relevant to the invention at this point, the side panel and bracket are designated with the same reference numerals. The same applies to the guide rail 20, into which the profile cross-section 18 can be integrally integrated. Variants are also conceivable in which the sun protection system does not require a guide rail at all and the profile cross-section is formed within a different vertical profile.

[0028] To secure the sword 16 against being pulled out of the profile cross-section 18, a locking bracket 22 is provided, which can be made of sheet metal. The locking bracket 22 has a vertical leg 24, which is screwed to a wall 26 of the profile cross-section 18 from the outside at one end face. The possibility of an inclined orientation of the component has already been mentioned above.

[0029] One of the angled horizontal legs 28 protrudes through a suitably shaped slot 30 in the wall 26 into the profile cross-section 18.

[0030] The sword 16 has a horizontally oriented recess 32 at the level of the horizontal leg 28, into which the horizontal leg 28 projects, so that the sword 16 can no longer be pulled out of the profile cross-section 18.

[0031] At the same time, the formation of the horizontal leg 28 and the slot-like, horizontally oriented recess 32 in the sword preserves a degree of freedom of movement of the sword in a direction horizontally parallel to a building surface to be shaded (not shown), which in Figs. 2 and 3 This is illustrated by the arrows "Y". In conjunction with an inner width of the profile cross-section 18 between the inner walls 34, which is larger than the width of the sword 16, the sword is able to compensate for changes in position due to thermal expansion or dimensional tolerances during manufacturing or assembly, so that no stress forces can occur in the sun protection system, the guide rails or frame elements of the window or a facade.

[0032] It may not be necessary to accommodate both blades of a sunshade system in the profile cross-section as described above. For example, the blade at one end of the sunshade system can be firmly anchored, while the blade 16 at the opposite end or in the middle can compensate for any unevenness by being accommodated in the guide cross-section as described above.

[0033] The solution described above is also suitable for several sun protection systems arranged side by side in a network, whose winding drives are coupled together. This is exemplified in Fig. 3 Illustrated. There, in the top view, two consoles 12, 112 of adjacent sun protection systems are shown, with all other parts of the systems not shown.

[0034] Both consoles 12, 112 are inserted into a common profile cross-section 18 with their swords 16, 116. The two swords 16, 116 are positioned at a variable distance from each other in the position shown and also have play with respect to the laterally located inner walls 34, 134, so that both consoles can move from their positions shown relative to each other and within the profile cross-section 118 in a direction parallel to the area to be shaded (see arrow).

[0035] The profile cross-section 118 is part of a facade construction, wherein the profile rail 136 forming it has lateral receptacles 138 into which guide rail inserts (not shown) can be mounted.

[0036] The locking bracket 122, which in turn has a vertical leg 124 and a horizontal leg 128, extends in this embodiment over the entire width of the profile cross-section 18, so that both brackets 12, 112 with their correspondingly designed horizontally oriented openings 32 are secured against being pulled out by means of a single locking bracket 122, which is structurally similar to the locking bracket 22. Fig. 1 and 2 corresponds.

[0037] The two consoles may also be connected or even formed as a single unit, in which case, of course, the relative freedom of movement between the consoles is eliminated.

[0038] The assembly is carried out by first fixing the profile rails with the profile cross-section 18, 118 to a window frame, a facade element or a building wall, whereby the profile rails themselves may already form as guide rails or be designed to receive guide rail inserts.

[0039] The brackets with their blades 16, 116 are then inserted into the profile cross-sections 18, 118, whereby the sun protection systems may be fully or partially pre-assembled, i.e., in such a case, the sun protection system is inserted into the profile cross-sections with both blades simultaneously. Fig. 2 The insertion direction is illustrated by the arrow at X.

[0040] The insertion depth is defined by a stop (not shown) at the upper edge of the profile cross-section 18, 118, so that the horizontally oriented openings 32 lie at the level of the slots 30 in the end walls of the profile cross-sections 18, 118 after insertion.

[0041] Finally, the locking brackets 22, 122 are inserted, with the horizontal legs 28 being inserted from the outside through the slots 30 into the horizontally oriented recesses 32 in the swords. The locking brackets 22, 122 are then screwed to the end wall 26 of the profile cross-section 18 using screws 40.

[0042] Fig. 4 shows a securing angle 122 which has a nose 142 at the center of the end of a horizontal leg 128, which projects between the two adjacent brackets 112 (see Fig. 3 ) and thereby limits their maximum displacement. In principle, this allows in Fig. 3The concept shown has a very large axial compensation, which could cause the consoles to shift even beyond the center position, but this is prevented by the nose 142.

[0043] By limiting the axial displacement of the brackets 112 when they are laterally positioned against the nose 142 as a stop, it is prevented that the fabric balls (not shown) move too far from the target positions in relation to the guide, which could otherwise have negative effects on the winding behavior and the fabric appearance as well as the fabric tension.

[0044] The nose 142 has chamfers 144 on its edges, so that the nose can be easily inserted between the two adjacent consoles during assembly.

[0045] The invention is not limited to one of the embodiments described above, but can be modified in many ways.

[0046] All features and advantages arising from the claims and the description, including constructive details, spatial arrangements and process steps, can be essential to the invention both individually and in various combinations. Reference symbol list
