Description

[0001] The invention relates to an awning with a fabric roller rotatably mounted about its axis, from which a shading element can be unwound, wherein the front end of the shading element in the extension direction is attached to an extendable extension profile, wherein the awning has at least one support surface for supporting the fabric roller, wherein the support surface is adjustable within an adjustment range and can be fixed at any point within the adjustment range.

[0002] Such an awning is known from EP 0 665 346 A1. Awnings with a support surface for supporting the fabric roller and the fabric roll wound on it are also known from FR 2 937 367 A1, DE 298 06 658 U1, US 1 765 451 A, EP 1 835 089 A2 and US 2008 / 289775 A1.

[0003] Such awnings with a support surface for the fabric roller and the fabric roll wound upon it are generally known. However, a disadvantage of these known awnings is that, due to their design, the support surface is only effective with respect to a single fabric roll diameter. If the extension length of the shading element changes and / or different materials are used for the shading element, the support surface can no longer effectively support the fabric roll due to the altered fabric roll diameter.

[0004] From DE 10 2015 303 242 A1, an awning is known in which a support device is provided to support the winding shaft against deflection. This support device is elastically pre-loaded by a compression spring in the radial direction towards the winding shaft to automatically adapt to changes in the diameter of the awning fabric's winding. A disadvantage of this design is that the maximum force for supporting the winding shaft is limited to the compressive force of the spring.

[0005] The object of the invention is to overcome these disadvantages and to provide an awning in which reliable support for the fabric roller can be provided.

[0006] This problem is solved according to the invention by an awning according to claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

[0007] A particular advantage of an awning with a fabric roller rotatable about its axis, from which a shading element can be unwound, wherein the front end of the shading element in the direction of extension is attached to an extendable extension profile, and wherein the awning has at least one support surface for supporting the fabric roller, is that the support surface is adjustable within an adjustment range and can be fixed at any point within the adjustment range.

[0008] The shading element can be a fabric such as an awning fabric or a fly screen, a transparent curtain, a roller blind or fabric or the like.

[0009] This allows the support surface to be adjusted and fixed within the adjustment range. This enables the position of the support surface to be adapted to the fabric roll diameter. For the purposes of the invention, the term "fabric roll diameter" refers to the diameter of the shading element when fully wound onto the fabric roller. The fabric roll diameter varies depending on the extension length and / or thickness of the material used for the shading element. By adjusting and fixing the support surface within the adjustment range, its position can be adapted. Accordingly, optimal positioning and fixing of the support surface ensures its proper functioning and the support of the fabric roller.

[0010] The support surface can be fixed at any position within the adjustment range using appropriate fastening elements. Adjustability can be stepless and / or incremental.

[0011] The adjustment range can be defined by adjustment elements such as threaded bolts and / or slides and / or cam guides. This includes linear movement and / or pivoting movement, or a superposition or a sequence of linear and pivoting movements, particularly with different curvatures and directions of curvature. This allows the support surface to be adjusted in three dimensions in space.

[0012] Preferably, the awning is a horizontally extendable awning or an awning extendable at a particularly acute angle to the horizontal, especially a folding-arm awning, or a vertical shading system. Furthermore, in any embodiment, lateral guide elements, in particular guide rails, can be arranged to guide the shading element and / or the extension profile. Thus, the arrangement according to the invention can be used in awnings of various types within the scope of the preamble.

[0013] In a preferred embodiment, the fabric roller is arranged in a housing; in particular, the housing can be closed by the extension profile when the awning is retracted. This not only improves the visual appearance of the awning but also ensures the protection of any awning components inside the closed housing from weather damage and / or soiling.

[0014] Preferably, the support surface is adjustable in the horizontal direction within the adjustment range. In particular, adjustability in one direction with at least one horizontal component is included.

[0015] In a preferred embodiment, the support surface is adjustable in the vertical direction within the adjustment range. In particular, adjustability in one direction with at least one vertical component is included.

[0016] In particular, the adjustability and fixability of the support surface within the framework of a swiveling movement, especially different curvature, a superposition and a series of linear movements and / or swiveling movements is possible.

[0017] Preferably, the support surface is supported by one or more support surface beams. In particular, the one or more support surface beams can be arranged, for example, on the inside of a housing or on another load-bearing part of the awning, such as a support tube and / or brackets.

[0018] In a preferred embodiment, the support surface is adjustable and lockable by means of threaded bolts that engage in and / or are supported by one or more support surface supports. In this case, the threaded bolts define the adjustment range. This allows the support surface to be adjusted and locked in a particularly simple manner by actuating the threaded bolts.

[0019] According to the invention, the support surface is adjustable along cam guides arranged in the lateral end plates of a housing that receives the fabric roller. In this case, the cam guides define the adjustment range. By means of such cam guide(s), the support surface can be adjusted and fixed in a low-wear and simple manner.

[0020] Of course, a combination of adjustable elements and a cam track system is also possible.

[0021] In a preferred embodiment, the fabric roller is movable back and forth in the extension direction of the extension profile. In particular, the fabric roller movement has at least one component in the extension direction of the extension profile and another component opposite to the extension direction of the extension profile.

[0022] This ensures that the fabric roll, which changes its diameter when the shading system is extended and retracted and is wound onto the fabric roller, always rests against the support surface. This supports the fabric roller against the weight of the system and / or any tension force acting on the shading element. This prevents deflection of the fabric roller, regardless of the fabric roll diameter, thus ensuring optimal fabric tension.

[0023] Preferably, the fabric roller is supported at its ends in sliding blocks that slide in guideways of bearing supports. Such an arrangement ensures that the fabric roller can be moved easily and with minimal wear, without requiring extensive assembly.

[0024] In particular, the fabric roller can be moved back and forth towards the extension profile, with its ends supported in sliding blocks that glide in guideways of bearing supports. This means that the fabric roller is floating. Such a floating mounting of the fabric roller, where it can be moved back and forth towards the extension profile, ensures that the fabric roll, which changes its diameter when the vertical shading system is extended and retracted, is always in contact with the support surface. This supports the fabric roller against the force of gravity and / or tension, ensuring optimal fabric tension, especially in the case of horizontally extending awnings. This prevents deflection of the fabric roller, regardless of the fabric roll diameter, thus guaranteeing optimal fabric tension.

[0025] In a preferred embodiment, the fabric roller is supported at its ends by pendulum arms, the pendulum arms being suspended about a pivot axis that lies parallel to the axis of the fabric roller but off-axis. This type of pendulum bearing ensures easy displacement of the fabric roller depending on its diameter, so that the fabric roller with the wound fabric roll is always in contact with the support surface and is thereby supported against the force of gravity and / or a tension force. This counteracts deflection of the fabric roller regardless of the fabric roll diameter, thus ensuring optimal fabric tension.

[0026] In a preferred embodiment, the support surface extends parallel to the axis of rotation of the fabric roller over the entire length, a portion of the length, or several sections of the fabric roller. The length of the fabric roller refers to its axial extent. In particular, the support surface can be made in one piece or in multiple pieces. The length of the support surface can also extend beyond the axial extent of the fabric roller. Preferably, the axial length of the support surface corresponds at least to the dimension of the wound fabric roll in the direction parallel to the fabric roller axis. This dimension of the fabric is commonly referred to as the width of the shading system.

[0027] Preferably, the support surface extends circumferentially over an angle of up to 30° or more than 30° of the fabric roller, in particular up to 60° or up to 90° or up to 120°. This achieves a particularly advantageous support of the fabric roller.

[0028] In a preferred embodiment, the support surface has one or more friction-reducing inserts and / or one or more friction-reducing pads and / or one or more friction-reducing coatings. Such friction-reducing inserts and / or pads and / or one or more friction-reducing coatings on the support surface reduce the static friction between the shading element and the support surface.

[0029] This facilitates the sliding of the fabric roll over the support surface when the fabric roller rotates. This prevents creases from forming when the vertical shading system is wound up and unwound.

[0030] In particular, such friction-reducing inserts and / or layers and / or coatings can extend over the entire surface of the support surface or be arranged in partial areas of the support surface. Specifically, such friction-reducing inserts and / or layers and / or coatings can be designed as strips running parallel and / or perpendicular to the fabric roll axis.

[0031] Two embodiments of the invention are illustrated in the figures and are explained below. They show: Fig. 1 shows a section of the side view of a horizontally extendable articulated arm awning; Fig. 2 shows a section of the side view of a vertical shading system.

[0032] In the Figure 1 The image shows a cross-section through the housing of a folding-arm awning. Such an awning, which can be extended horizontally or at an acute angle to the horizontal, can be mounted on a facade to shade a terrace.

[0033] The awning has a housing 1. The housing 1 is attached to a console 10. In A fabric roller 4 is rotatably mounted in the housing 1. The fabric can be unwound from the fabric roller 4 in the horizontal direction a at this point. Figure 1 The shading element 2 extends to the right. The front end of the shading element 2 is attached to the extension profile 3. The extension profile 3 can also be extended and retracted by means of articulated arms 7. The housing 1 is closed by the extension profile 3 when retracted, thus protecting the internal parts from the weather.

[0034] A support surface 5 is arranged to support the fabric shaft 4 with the fabric bale 6 wound on it. According to the invention, the support surface 5 can be adjusted and fixed within its adjustment range in the vertical direction 8 and in the horizontal direction 9 by means of threaded bolts (not shown). These threaded bolts engage in several support surface supports.

[0035] In the Figure 2 The image shows a cross-section through the housing of a vertical shading device. Such a vertical shading device can be mounted, for example, in a window reveal or on a facade to shade a window, or also, for example, on a patio roof or a conservatory.

[0036] The vertical shading system has a housing 11. The housing 11 is attached to mounting brackets 10. A fabric roller 14 is rotatably mounted in the housing 11. The shading element 12, which extends vertically downwards in the direction b, can be unwound from the fabric roller 14. The front end of the shading element 12 is attached to the vertically downward-moving extension profile 13. The extension profile 13 is guided by the guide element 17 on a vertically tensioned cable.

[0037] A support surface 15 is arranged to support the fabric shaft 14 with the fabric bale 16 wound on it. According to the invention, the support surface 15 can be adjusted and fixed within its adjustment range in the vertical direction 8 and in the horizontal direction 9 by means of threaded bolts (not shown).

[0038] In both cases of the folding arm awning according to Fig. 1 as well as the vertical shading according to Fig. 2The position of the support surface 5, 15 can thus be adjusted to the diameter of the shading element 2, 12 when fully wound onto the fabric roller 4, 14. For example, if the extension is shortened according to the length of the fully unwound shading element 2, 12, the diameter of the shading element 2, 12 when fully wound onto the fabric roller 4, 14 would decrease accordingly. The position of the support surface 5, 15 can therefore be adjusted by being adjustable and lockable within its adjustment range. This ensures the support of the fabric roller and the wound fabric roll.

[0039] This means that the basic design of the awning can be used for a wide variety of designs and applications, as both the material of the shading element and the respective width and extension of the awning can be adapted to the installation situation.
