Description

[0001] The invention relates to a shading device with a housing and a fabric shaft rotatably mounted in the housing, from which a shading element can be unwound, wherein the fabric shaft is mounted at both its ends with a fabric shaft bearing in a bearing support arranged at each end.

[0002] Such shading systems are known. In these systems, the fabric roller, along with its end bearings, is pre-assembled in the housing. A disadvantage is that installing a shading system with a pre-mounted fabric roller requires lifting and mounting very heavy loads. Another disadvantage is that replacing the fabric roller is very complex and, for example, in the case of a vertical shading system installed in a building recess, necessitates dismantling the entire system.

[0003] The object of the invention is to further develop a shading device in such a way that the removal and insertion of the fabric roller with the shading element is made possible in an easy manner, in order to facilitate the assembly of the shading device and the replacement of the fabric roller with the shading element.

[0004] This problem is solved according to the invention by a shading arrangement as described in claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

[0005] A particular advantage of shading with a housing and a fabric roller rotatably mounted in the housing, from which a shading element can be unwound, wherein the fabric roller is supported at both its ends with a fabric roller bearing in a bearing support arranged at each end, is that the bearing supports can be pivoted and / or moved from a pre-assembly position, in which the fabric roller bearings can be inserted into or removed from the bearing supports, to a final assembly position with the fabric roller bearings inserted into the bearing supports.

[0006] The shading can be in particular a vertical shading system, an awning, especially a folding arm awning or a patio roof awning, or a roller shutter.

[0007] The shading element can be, in particular, an awning fabric or a fly screen, a transparent curtain, a roller shutter, a blind, or fabric. It can also be, in particular, a printed advertising banner.

[0008] The front end of the shading element can be attached to an extension profile that can be extended horizontally, vertically, or at an angle to the horizontal.

[0009] The pivotability of the bearing supports, which accommodate the end bearings of the fabric roller, between a pre-assembly position and a final assembly position allows for easy removal and insertion of the fabric roller with the shading element wound onto it in the pre-assembly position. This initially simplifies the installation of the shading system, as the housing can first be mounted and, for example, secured to mounting brackets and / or attached to a building structure, and then the fabric roller can be inserted into the housing. Furthermore, the invention allows for easy subsequent replacement of the fabric roller with the shading element wound onto it, even after the shading system has been installed. This is particularly advantageous, for example, in the case of vertical shading installed in a building recess.This allows, for example, advertising banners to be regularly replaced without having to dismantle the entire shading system.

[0010] Preferably, after pivoting from the pre-assembly position, a linear displacement within the housing into the final assembly position takes place, in particular a linear displacement in the horizontal direction.

[0011] The movement from the pre-assembly position to the final assembly position in this case is accomplished through two successive steps: first a pivoting motion, then a linear movement. The linear movement onto corresponding supports secures the bearing supports against pivoting in the final assembly position.

[0012] Preferably, the bearing supports are pivotable by 70° to 100°, in particular by 90°.

[0013] Preferably, the bearing supports each have a U-shaped receptacle for receiving a fabric shaft bearing, with the opening of the U-shaped receptacle facing upwards in the final assembly position.

[0014] The U-shaped receptacle preferably forms a positive fit with a sliding block in which the respective fabric roller end is rotatably mounted. Because the U-shaped receptacle for each fabric roller bearing is oriented upwards in the final assembly position, the fabric roller is automatically secured in the U-shaped receptacle of the bearing support by its own weight in the final assembly position.

[0015] Preferably, the bearing supports are locked in the final assembly position, in particular by means of a positive locking connection of the bearing supports to the housing.

[0016] By locking the bearing supports in this way in the final assembly position, the bearing supports together with the fabric shaft are secured and fixed.

[0017] Preferably, the bearing supports each have at least one bolt which engages in a cam guide of a head plate of the housing and forms the axis of rotation of the pivoting movement of the bearing supports.

[0018] In particular, the bearing supports can each have at least one second bolt which rests on a support of the head plate in the final assembly position and / or which, after pivoting into the pre-assembly position, rests on a support of the head plate and secures the bearing support against pivoting beyond the pre-assembly position.

[0019] Alternatively, the housing can have a head plate at each end, each with at least one bolt, wherein the bolt engages in a cam guide of the respective bearing support and forms the axis of rotation for the pivoting movement of the bearing support. In this case, the head plate can, in particular, have a second bolt which secures the bearing support in the pre-assembly position against pivoting beyond the pre-assembly position.

[0020] The term "end-side" refers to the two ends of the fabric roller in the housing of the shading system.

[0021] In a preferred embodiment, each bearing support has three bolts on the outside, which form a triangle, in particular a right-angled triangle, and which engage in cam guides in a head plate of the housing or rest on supports of the head plate, with one of the bolts forming the axis of rotation when pivoting into the pre-assembly position.

[0022] "Outside" refers to the direction opposite to the fabric shaft in relation to the bearing supports, i.e., towards the top plate of the housing and away from the fabric shaft inserted between the bearing supports.

[0023] In this arrangement, the three bolts of each bearing support preferably rest on supports in the final assembly position, the bolts forming a right-angled triangle and being spaced apart in such a way that, in the final assembly position, the upper bolt of the bearing support rests on the support in the housing after a linear process, enabling pivoting into the pre-assembly position and securing the bearing support in the pre-assembly position against further pivoting, on which, in the final assembly position, the bolt rests at the opposite end of the hypotenuse of the triangle formed by the three bolts.

[0024] This means that the length of the leg of the triangle spanned by the bolts that lies horizontally in the final assembly position corresponds to the length of the linear travel path plus the length of the leg of the triangle spanned by the bolts that stands vertically in the final assembly position.

[0025] In an alternative embodiment, the housing has at each end a head plate with three bolts pointing towards the bearing support, which form a right-angled triangle and engage in cam guides in each bearing support, with the bolt at the right angle forming the axis of rotation.

[0026] Preferably, the housing has an openable shaft in which a removable plug for connecting an electric fabric roller drive to a power supply line is arranged.

[0027] Preferably, the housing has a cover plate at each end, which secures the bearing supports against displacement in the final assembly position.

[0028] In a preferred embodiment, the fabric shaft can be moved forwards and backwards in the extension direction; in particular, the fabric shaft can be supported at its ends in sliding blocks that slide in cam guides of the bearing supports.

[0029] Preferably, the shading system has a support surface against which the fabric bale rests, particularly regardless of its diameter which changes depending on the extension range of the extension profile, and which counteracts any deflection of the fabric shaft with the fabric bale.

[0030] The term "fabric roll" refers to the shading element wound onto the fabric roller. This support surface, located below the fabric roller, reliably counteracts deflection of the roller and the shading element wound onto it due to its own weight, particularly in very wide systems (i.e., those with a very long fabric roller), thus preventing creases in the winding.

[0031] An embodiment of the invention is shown in the figures and is explained below. The figures show: Fig. 1 A side view of the housing of a shading system without an outer cover plate, showing the contours of the bearing support and the head plate; Fig. 2 The side view of the head plate and the bearing support; Fig. 3 A perspective view of a section of the housing of the shading system. Figure 1 in the final assembly position; Fig. 4 a perspective view of a section of the shading housing after Figure 1 in the intermediate position; Fig. 5 a perspective view of a section of the housing of the shading system after Figure 1 in the pre-assembly position with the fabric roller inserted; Fig. 6 a perspective view of a section of the shading housing after Figure 1 in the pre-assembly position with the fabric roller removed.

[0032] The in the Figures 1 to 6 The illustrated embodiment of the invention shows a vertical shading system with a downwardly extendable shading element.

[0033] Fig. 1 shows a side view of the housing 1 of a shading system without an outer cover plate, showing the contours of the bearing support 2 and the head plate 3. Fig. 2 Figure 1 shows the side view of the head plate 3 (left) and the bearing support 2 (right). The illustration is shown according to... Figure 1 The bearing support 2 is located in the final assembly position relative to the head plate 3 and the housing 1.

[0034] Fig. 3shows a perspective view of a section of housing 1 after shading Figure 1 in the final assembly position. Fig. 4 shows a perspective view of a section of housing 1 after shading Figure 1 in the intermediate position. Fig. 5 shows a perspective view of a section of housing 1 after shading Figure 1 in the pre-assembly position with the fabric roller inserted 4. Fig. 6 shows a perspective view of a section of housing 1 after shading Figure 1 in the pre-assembly position with the fabric roller removed 4.

[0035] The housing 1 has a back 11, a top 12, a front 13, and a bottom 14. The housing 1 of the vertical shading system can be attached to a building structure (not shown) either indirectly, for example by means of mounting brackets, or directly at its back 11. The terms front and back refer to the installation situation of the shading system, as its back abuts a building structure (not shown) and it is mounted to this structure.

[0036] The bearing support 2 serves to accommodate a fabric shaft bearing assigned to each end of the fabric shaft and has a U-shaped receptacle 24 for this purpose. In the final assembly position of the bearing support 2, the U-shaped receptacle 24 for the fabric shaft bearing points upwards, so that the fabric shaft bearing is securely held in the U-shaped receptacle 24 by its own weight.

[0037] The bearing support 2 has three bolts 21, 22, 23 on its outer side, forming a right-angled triangle. In the final assembly position according to the Figure 1 and 3 The three bolts 21, 22, 23 rest in a cam guide 31 in the head plate and on the corresponding supports 32, 33 of the head plate. The cam guide 31 in the head plate has an opening whose width is designed such that the bolt 21 of the bearing support, which lies in the cam guide, can be inserted through the opening into the cam guide 31.

[0038] To remove or insert the fabric roller 4 into the bearing supports 2, the bearing support 2 must be moved from the inside into the Figure 1 and 3The final assembly position shown is horizontally movable along the path C. The bolt 21 is moved at the right angle of the right-angled triangle formed by the bolts 21, 22, 23 from position 31a in the final assembly position along path C towards the front 13 to position 31b in the intermediate position in the guide 31 in the end plate 3. This means that the front housing 13 and the bottom housing 14, which are connected to the bearing supports 2 carrying the fabric shaft bearings 41 and arranged at both ends of the fabric shaft 4, move like a drawer from the final assembly position in the end plates 3, which are also arranged at both ends of the fabric shaft 4, to the intermediate position as shown. Figure 4 can be pulled forwards. In this intermediate position according to Fig. 4The bolt 21 is located at the right angle of the triangle formed by the bolts 21, 22, 23 in the cam guide 31 of the head plate 3 in the forward position 31b. In this intermediate position according to Fig. 4 The two other bolts 22, 23 are moved away from the supports 32, 33 on the head plate 3, so that the bearing supports 2 together with the cloth shaft 4 received therein can be pivoted around the axis of the bolt 21 at the right angle of the triangle until they reach the pre-assembly position, as indicated by the arrow 25 in Fig. 4 This is illustrated. As explained, bolt 21 at the right angle of the triangle formed by bolts 21, 22, 23 forms the axis of rotation for the pivoting movement.

[0039] The pre-assembly position with the fabric roller 4 inserted into the bearing supports 2 and the shading element wound onto the fabric roller 4 is in Fig. 5 depicted.

[0040] The distance A between the bolts 21, 23 forming the horizontal leg of the triangle in the final assembly position is selected such that the distance A corresponds to the sum of the distance between the bolts 21, 22 forming the vertical leg of the triangle in the final assembly position, plus the travel distance C from the final assembly position 31a to the intermediate position 31b. This ensures that the upper bolt 22 in the final assembly position is in the pre-assembly position according to Fig. 5 on the support 33 on the head plate 3, which in the final assembly position receives the bolt 23, which is located at the end of the horizontal leg of the triangle in the final assembly position. Because the upper bolt 22 in the final assembly position is in the pre-assembly position according to Fig. 5When the bearing support rests on the support 33 on the head plate 3, the bearing bracket is secured against further pivoting beyond the pre-assembly position. Accidental slippage of the bolt 22 beyond the support 33 is prevented by the fact that the bolt 22, which forms the axis of rotation, is secured in the cam guide 31 in the head plate against further movement towards the front of the shading.

[0041] After pivoting the bearing supports 2 into the pre-assembly position according to Fig. 5 The fabric roller 4 with the shading element wound on it can be removed forwards from the bearing supports 2, as shown in Fig. 6 is shown. In the pre-assembly position of the bearing support 2 according to the Figures 5 and 6The opening of the U-shaped receptacle 24 faces forward, allowing the fabric roller 4 with the fabric roller bearings 41 at both ends of the fabric roller to be removed from their respective bearing supports 2. Insertion of the fabric roller is carried out accordingly in reverse, by moving the bearing support 2 into the pre-assembly position as shown. Fig. 6 The fabric roller 4 with the fabric roller bearings 41 is pivoted and inserted into the U-shaped receptacle 24 on the bearing support 2. The bearing support 2 is then moved to the intermediate position according to... Fig. 4 swivelled and then into the final assembly position according to Figure 3 inserted. In the final assembly position, the bearing support is additionally secured against slipping out of the final assembly position by the positive locking mechanism 10 between the bearing support 2 and the housing 1.

[0042] The invention significantly simplifies the installation of a shading system, as initially only the housing 1, without a fabric roller 4 pre-assembled within it, needs to be mounted on a building structure. After mounting the housing 1, the fabric roller 4 can then be inserted into the bearing supports 2 in the pre-assembly position. After moving the bearing supports 2 from the pre-assembly position to the intermediate position, they can be moved from the intermediate position to the final assembly position. In the final assembly position, the bearing supports are additionally secured at both lateral ends of the shading system by cover plates (not shown). Besides simplifying installation, the invention also allows for easy subsequent replacement of the fabric roller and the shading element wound upon it.
