From the documents DE 10 2006 059470 A1 A support device is known for supporting a bale of a shading element that can be wound on a winding shaft, the support device having a support surface with at least one friction-reducing insert and / or support.

From the document BE 1 018 229 A3 horizontal shading is known.

The object of the invention is to simplify the assembly of such vertical shading.

This object is achieved according to the invention by vertical shading according to claim 1 and claim 2. Advantageous developments of the invention are specified in the subclaims.

In the case of the vertical shading according to the invention with a cloth shaft rotatably mounted in a housing, from which a shading element can be unwound, the front end of the shading element being fastened to an extension profile which can be extended downwards, the housing of at least is held two fastening brackets, it is provided that at least one of the fastening brackets has a housing receptacle which is adjustable at least in the vertical direction relative to a base body of the bracket.

It is particularly advantageous in the case of vertical shading with a cloth shaft rotatably mounted in a housing, from which a shading element can be unwound, the front end of the shading element being fastened to an extension profile which can be extended downwards, the housing being held by two vertical guide rails at least one fastening bracket is arranged, which has a housing receptacle that is adjustable at least in the vertical direction relative to a base body of the bracket. The housing and the guide rails can indirectly or directly form a positive connection.

On the one hand, this simplifies the installation of vertical shading, since any tolerances can be compensated for by the adjustability of at least one of the fastening brackets. If, for example, three fastening brackets are arranged, at least the middle of the three fastening brackets can be designed as an adjustment bracket. In this way, deflections of the housing can be compensated for in very wide systems, for example up to 6 m or more.

In the case of vertical shading, the housing of which is supported by vertical guide rails, the arrangement of one or more adjustment brackets in the area between the vertical guide rails can also counteract deflections of the housing in very wide systems, for example up to 6 m or more.

The base body of the console can thus be attached to a lintel or a winter garden or a patio roof or pergola in at least one of the fastening brackets, the housing receptacle being adjustable relative to this base body of the console at least in the vertical direction and being fixable in the desired position on the base body. The housing receptacle of the mounting bracket is used to hold and Bracket for the housing of the vertical shading on the console. By means of the adjustment bracket, a variable fastening of the housing of the vertical shading is possible in the vertical direction compared to the base body of the bracket. More than one adjustment console can also be provided, or all consoles can be adjustment consoles. As a result, the entire vertical shading can be aligned with the respective base bodies by adjusting the housing receptacles.

The shading element can be a cloth such as an awning cloth or a fly screen, a transparent curtain, a roller blind or fabric or the like.

The provided adjusting screw enables easy actuation and adjustment of the housing receptacle relative to the base body of the console to the desired level.

The housing receptacle can be moved in the horizontal direction relative to the base body of the console parallel to the axis of rotation of the fabric shaft by means of at least one adjusting screw. Since the axis of the fabric wave runs horizontally, this designates horizontal adjustability from right to left and vice versa in relation to the structure on which the vertical shading is arranged. Such a movability of the housing receptacle in relation to the base body in the horizontal direction can also compensate for any assembly tolerances in the horizontal direction. In particular, it is possible to compensate for the distance between the housing receptacles if an equidistant mounting of the base bodies of the brackets should not be possible due to structural conditions.

The housing receptacle is preferably movable relative to the base body of the console in the horizontal direction perpendicular to the axis of rotation of the fabric shaft, in particular by means of at least one adjusting screw. With the direction A direction of movement away from the building body or towards the building body on which the vertical shading is arranged is designated horizontally perpendicular to the fabric shaft axis. Such adjustability can compensate for positional deviations caused by the building structure, as may be caused, for example, by projections of the wall.

In a preferred embodiment, the housing receptacle has a wedge-shaped bevel as a support surface, which rests on a corresponding bevel of the base body of the console, the housing receptacle having at least one thread into which an adjusting screw engages, which is supported on the base body of the console and / or wherein the base body of the console has at least one thread into which an adjusting screw engages, which is supported on the housing receptacle. Such a wedge-shaped support provides a sufficiently large support surface for the housing receptacle on the base body while at the same time advantageously moving the housing receptacle on the base body.

The housing receptacle preferably has vertical elongated holes which are penetrated by clamping screws screwed into the base body of the console, by means of which the housing receptacle is non-positively fixed to the base body of the console in the desired position. Such elongated holes allow the housing receptacle to be moved and aligned on the base body of the console. In the desired position, the housing receptacle can then be non-positively fixed by clamping the base body of the console by tightening the clamping screws.

In a preferred embodiment, the fabric shaft can be moved back and forth in the direction of the extension profile, the fabric shaft being supported at its ends in sliding blocks which slide in guide rails of bearing supports. This means that the fabric shaft is floating.

The vertical shading particularly preferably has a support surface for supporting the fabric shaft. The support surface can extend over the entire length or part of the length of the fabric shaft or a plurality of sections of the fabric shaft. The support surface can not be made in one piece or in several parts.

The length of the fabric shaft means the extension of the fabric shaft in the axial direction of the fabric shaft axis.

A deflection of the fabric shaft can be counteracted by means of such a support surface. In conjunction with a floating mounting of the fabric shaft, in which the fabric shaft can be moved back and forth in the direction of the extension profile, it is guaranteed that the fabric bale that changes its diameter when the vertical shading extends and retracts and that is wound on the fabric shaft bears against the support surface and thereby the fabric shaft is supported against the weight. This counteracts a deflection of the fabric shaft regardless of the fabric bale diameter, which can ensure an optimal fabric level.

By means of a floating mounting of the cloth shaft, which is supported at its ends in sliding blocks that slide in the guide rails of bearing supports, the cloth bale can rest against the support surface for supporting the cloth shaft regardless of its diameter, which changes depending on the extension of the extension profile, in order to to counteract a deflection of the fabric shaft with the fabric bale. The term "bale of cloth" means the winding of the shading element on the cloth shaft.

Such a support surface for supporting the fabric shaft can be formed in one piece throughout the entire length or part of the length of the fabric shaft. Alternatively, several sections can be arranged along the fabric shaft axis below the fabric shaft in order to support the fabric shaft. The term support surface is thus a one-part as well as a multi-part design of such a support surface includes. The length of the support surface can also extend beyond the axial extent of the fabric shaft.

The support surface for supporting the fabric shaft can extend in the circumferential direction over an angle of over 30 ° of the fabric shaft, in particular up to 60 ° or up to 90 ° or up to 120 °.

In a preferred embodiment, the vertical shading has a support surface for supporting the fabric shaft, the support surface having friction-reducing inserts and / or supports and / or a friction-reducing coating.

Such friction-reducing inlays and / or overlays and / or a friction-reducing coating of the support surface reduces the static friction between the shading element and the support surface. This makes it easier to slide the bale of fabric over the support surface when the fabric shaft is rotated. This counteracts the formation of folds when winding up and unwinding the vertical shading.

Such friction-reducing inlays and / or overlays and / or coatings can extend over the entire surface of the support surface or can be arranged in partial areas of the support surface. In particular, such friction-reducing inlays and / or overlays and / or coatings can be formed in strips in a manner parallel and / or perpendicular to the fabric shaft axis.

In a preferred embodiment, the vertical shading has vertical guide rails in or on which the extension profile and / or side edges of the shading element are guided.

Such vertical guide rails reliably prevent a swinging and / or deflection, in particular of the extension profile, even in the event of wind loads.

Particularly preferably, the shading element has half-zippers on its edges extending in the extending direction, which cooperate with corresponding half-zippers in vertically running guide rails. In this preferred embodiment, the shading element therefore has zipper-like elements at its edges extending in the extending direction, which form one side of a zipper and which interact with corresponding counterparts in vertically extending guide rails.

In the case of so-called zip awnings, half-zippers are arranged on both vertical side edges of the fabric, which cooperate with corresponding counterparts arranged in vertical guide rails and produce a zipper-like vertical connection between the fabric and guide rail.

Especially in the case of so-called zip awnings with zip connections on both sides between the vertically running fabric edges and the vertically running guide rails, it is particularly advantageous if a high tensile force is applied by the extension profile when the shading element is extended. This high tensile force is ensured in the case of the vertical shading system according to the invention in that the extension profile has at least one additional weight.

In a preferred embodiment, the extension profile has at least one removable additional weight. With such an additional weight, an optimal cloth stand can be guaranteed when the vertical shade is extended.

The fact that the extension profile has at least one additional weight facilitates the assembly of the vertical shading on the one hand. The vertical shading can therefore be installed before the additional weight is installed. After the installation of the vertical shading at the installation location, the at least one additional weight can then be attached to the extension profile become. Several additional weights can also be attached to the extension profile.

The extension profile can have one or more additional weights that can be removed in particular. As a result of these additional weights, which are attached to the mounting location in or on the extension profile after the installation of the vertical shading, the tensile force of the extension profile on the downwardly unwound shading element is increased due to the weight of the additional weights. As a result, an optimal cloth level of the downwardly extending shading element is achieved.

In a preferred embodiment, the extension profile can be opened in several parts, with at least one additional weight in the extension profile. In particular, one or more additional weights can be positively inserted in the extension profile.

The interior of the extension profile is thus preferably accessible by opening the multi-part extension profile. This accessible interior of the extension profile particularly preferably has corresponding geometric dimensions, with the exception of one or more additional weights, in which the additional weights lie in a form-fitting manner. A positive hold ensures that the additional weight (s) are securely held and the additional weight (s) are secured and fixed in the extension profile.

The receiving profile preferably has receiving areas and / or fastening areas for attaching and / or receiving the at least one additional weight. This makes it possible to insert and / or clip and / or screw one or more additional weights into the extension profile and / or into corresponding receiving areas on the extension profile.

In particular, it is thus possible, for example, to clip one or more additional weights behind corresponding undercuts to define the extension profile and / or to attach it to the extension profile using fastening screws. One or more additional weights can be attached to or in the extension profile in a positive and / or non-positive manner.

It is therefore possible to insert appropriately designed additional weights in corresponding receiving areas in or on the extension profile and / or to secure them by means of clamping elements and / or to fix them in or on the extension profile by means of screw connections.

If the extension profile can be opened in several parts and one or more additional weights are inserted into the extension profile, the extension profile can be closed again after the installation of one or more additional weights, so that it has a closed contour on the outside and the visual design of the vertical shading and in particular the extension profile the additional weights are not affected.

One or more additional weights are preferably detachably attached to or in the extension profile. This not only makes it possible to mount the additional weight (s) only after the vertical shading has been installed, but also to dismantle it. This can be done, for example, for maintenance purposes or when the shading element is replaced, which makes handling easier.

An embodiment of the invention is shown in the figure and is explained below. It shows:

Fig. 1

a perspective view of a vertical shade;

a rear view of the housing of the vertical shading Fig. 1 ;

Fig. 3

the section A - A through the mounting bracket of the vertical shading Fig. 2 ;

Fig. 4

a rear view of another embodiment of a vertical shade.

In the figures, identical components and assemblies of the vertical shading are provided with the same reference symbols.

In the Fig. 1 a perspective view of a vertical shade is shown. Such vertical shading can be installed, for example, in a window reveal or on a facade for shading a window, or also, for example, on a terrace roof or a winter garden.

The vertical shading has a housing 1. A cloth shaft is rotatably mounted in the housing 1. The shade element 2, which can be extended downwards in the vertical direction, can be unwound from the fabric shaft. The front end of the shade element 2 is fastened to the extension profile 3, which can be moved vertically downward. In the illustrated embodiment, it is a so-called zip awning, in which the vertically running lateral fabric edges of the shading element 2 have zipper halves, which interact with corresponding counterparts in the vertical guide rails 4, 5. These zipper connections with the corresponding counterparts in the vertical guide rails 4, 5 reliably prevent the shading element 2 from fluttering and bulging, and also preventing the extension profile 3 from hitting even when wind loads occur.

The extension profile 3 has a number of additional weights which are mounted on the extension profile 3 after the vertical shading has been installed. As a result, the effective weight G in the direction of the arrow is increased, whereby an optimal working of the zipper connections of the shading element 2 on the vertical side edges with the corresponding counterparts in the vertical rails 4, 5 is improved. Due to the additional weights on the extension profile 3 Weight force G increased in the vertical direction downward, which acts on the shading element 2. With the additional weights, the cloth level of the vertical shading is improved. Due to the fact that the additional weights can be removed from the extension profile, it is possible to first mount the vertical shading without these additional weights and after the housing 1 with the cloth shaft rotatably mounted therein and the vertical guide rails 4, 5 are mounted, the additional weights can be attached to the extension profile become. This facilitates the assembly of the vertical shading and, on the other hand, after the complete assembly including the additional weights arranged on the extension profile, an optimal cloth stand and an optimal working method of the zippers on the side edges of the shading element 2 are guaranteed.

In Fig. 2 the rear view of the housing 1 of the vertical shading with the vertical guide rails 4, 5 is shown. The housing 1 is fastened to the structure, not shown, by means of three fastening brackets 6. The representation according to the Figures 1 and 2 is not to scale, but only schematic. In fact, the width of the housing 1 in the image plane according to the Fig. 2 turn out to be significantly larger than the length of the guide rails 4, 5. This means that the housing 1 can accommodate, for example, a fabric shaft up to 6 meters long. The distance between the mounting brackets 6 is correspondingly large. The fastening brackets 6 are adjustable brackets 6. According to section AA Fig. 2 by such an adjustable console 6 shows Fig. 3 ,

The brackets 6 have a base body 61, which is fixed to a structure, not shown, by means of screw connections, not shown. A housing receptacle 62 with a hook 63 is fastened to the base body 61 of the console 6 and is overlapped by a corresponding projection on the housing 1. The housing receptacle 62 has elongated holes 64 through which clamping screws 65 pass. As shown by the double arrow 66, the housing receptacle 62 can be displaced in the vertical direction upwards and downwards relative to the base body 61 of the console due to the elongated holes 64 and then in the desired position Alignment can be determined by tightening the clamping screws 65 on the base body 61. Due to the vertical adjustability of the housing receptacle 62 relative to the base body 61 of the bracket 6, any assembly tolerances when fastening the base body 61 to the structure can be compensated for. In addition, a deflection of the housing 1 can be achieved by a corresponding adjustment of the middle bracket with a total of 3 brackets Fig. 2 be balanced.

In Fig. 4 the rear view of the housing 1 of a further embodiment of a vertical shade with the vertical guide rails 4, 5 is shown. The housing 1 is positively mounted on the guide rails 4, 5 from above by corresponding connecting elements on the housing and carried by the guide rails 4, 5. For this purpose, the housing 1 has corresponding pins which engage positively from above in the guide rails 4, 5.

In the middle between the two guide rails 4, 5, a mounting bracket 6 is attached to the structure, not shown. The representation according to the Figure 4 is not to scale, but only schematic. In fact, the width of the housing 1 in the image plane according to the Fig. 4 turn out to be significantly larger than the length of the guide rails 4, 5. This means that the housing 1 can accommodate, for example, a fabric shaft up to 6 meters long. The distance between the guide rails 4, 5 is correspondingly large.

The mounting bracket 6 is an adjustable bracket 6, as shown on the Figure 3 was explained. Due to the vertical adjustability of the housing receptacle 62 relative to the base body 61 of the console 6, a deflection of the housing 1 can be compensated for by a corresponding adjustment of the console 6 and a deflection of the housing can thus be prevented. As an alternative to the schematic representation according to Fig. 4 For example, in the case of very wide shading, several adjustment brackets can be arranged for holding and supporting the housing in the area between the vertical supports.
