[0002] shading device

[0003] The invention relates to a shading device, such as a screen or the like.

[0004] Known shading devices have a central support element connected to several tensioning elements. A shading element is arranged between each adjacent tensioning element. It is known that the tensioning elements are rod-shaped and that textiles are used as the shading elements. Furthermore, support struts are connected to the support element and to each of the tensioning elements. The support struts are slidably connected to the support element to allow the shading device or screen to be opened and closed.

[0005] Especially when closed, the problem is that the shading elements can be damaged by weather, such as strong winds, or by vandalism. Therefore, it is necessary to protect them by, for example, placing a cylindrical cover over the closed shading element. However, this adds extra effort when opening and closing.

[0006] The object of the invention is to create a shading device in which the shading elements are well protected in the closed state. This object is achieved according to the invention by the features of claim 1.

[0007] The shading device according to the invention is designed such that each of the individual clamping elements has a surface element or is designed as a surface element. The surface elements are designed such that, in the closed state of the shading device, they form a shell element. In particular, in the closed state, the surface elements abut each other along their longitudinal sides or have only a small gap between them. If, for example, four clamping elements and thus four surface elements are provided, a substantially cuboid element with a square cross-section is formed in the closed state. The shading elements arranged between the clamping elements are protected by the surface elements, since they are located within them in the closed state.Therefore, with the shading device according to the invention, it is not necessary to pull an additional cover over the shading device in the closed state for protection, since the protection in the closed state is automatically provided by the surface elements.

[0008] The shell element formed by the surface elements thus surrounds the support element in the closed state, or the support element is arranged within the surface elements in the closed state.

[0009] In particular, four clamping elements are arranged regularly around the circumference of the support element. When four clamping elements are provided, they are thus arranged at an angle of 90 degrees to each other. It is also possible to provide a larger number of clamping elements, for example eight clamping elements, which then form an octagonal cross-section when closed. In a particularly preferred embodiment, the clamping elements are connected to the support element via a plate-shaped retaining element. The retaining element is arranged, in particular, at an upper end of the support element, similar to a roof. When four clamping elements are provided, the retaining element is therefore preferably square. When closed, the outer surfaces of the square are flush with the corresponding outer surfaces of the plate elements.The connection between the holding element and the clamping elements is usually made via a hinge joint or the like.

[0010] Furthermore, it is particularly preferred that the clamping elements have a frame that supports the surface element. This makes it possible to connect the frame element with different surface elements, depending on the desired embodiment, or to easily replace the surface elements. This also allows for a very stable structure with low weight.

[0011] The surface elements can be made of textile or be rigid, particularly from plastic. They can also be designed, for example, as photovoltaic elements. Naturally, combinations of differently designed surface elements are also possible, so that, for example, part of a surface element is made of textile and part of the same surface element is made of plastic. Furthermore, different surface elements of a shading device can have different designs.

[0012] In a preferred embodiment of the shading device according to the invention, an electrical and / or mechanical actuating element for opening and closing the shading device is integrated into the support element. Particularly when an electrical actuating element is provided, it is preferred that the surface elements have photovoltaic elements and that a battery is additionally provided. Furthermore, the support element can be connected to a base. A battery, a motor, or other auxiliary device could then be integrated into this base, whereby such auxiliary devices can, of course, also be integrated into the support element itself.

[0013] In a preferred embodiment, the base is designed to be connected to, in particular, foldable seating elements. The number of seating elements preferably corresponds to the number of mounting elements. This has the particular advantage that it is possible to arrange the individual elements in such a way that, when the shading device is closed and the seating elements are folded in, they form a common, and in particular, enclosed, housing element together with the surface elements. In this respect, the seating elements also serve to protect the shading device from damage.

[0014] In addition to incorporating auxiliary devices into the support element and / or the base, it is also possible for auxiliary devices, such as radiant heaters, cooling elements, or the like, to be supported by the clamping elements. For example, the cooling elements could be components that generate a mist of moisture. The corresponding liquid could be stored in a container within the base, with the liquid being circulated by an electric pump, which could also be located in the base or the support element.

[0015] The invention is explained in more detail below with reference to a preferred embodiment and the accompanying drawings.

[0016] They show:

[0017] Fig. 1 shows a schematic longitudinal section of a shading device according to the invention in the closed state, Fig. 2 shows a schematic top view of the shading device in the open state and

[0018] Fig. 3 shows a schematic sectional view along line III-III in Fig.

[0019] 2.

[0020] The figures show the essential elements of a preferred embodiment of the shading device according to the invention.

[0021] The shading device, designed in particular as a screen, has a central support element 10, which may be cylindrical in shape. A retaining element 12 is rigidly connected to the support element 10 at one upper end. The retaining element 12 is pivotably connected to a mounting element 14 via a joint 16 along each of its longitudinal sides. In the illustrated embodiment, the retaining element 12 is square, so that one mounting element 14, i.e., a total of four, is pivotably arranged on each of the four longitudinal sides. A shading element 18 is arranged between each adjacent mounting element 14. The shading elements 18 are made in particular of a flexible material, such as a textile.

[0022] To open and close the shading device or screen, support struts 20 are connected to the tensioning elements 16 and the support element 10, with at least one support strut 20 being provided for each tensioning element 14. The support struts 20 are preferably pivotally connected to the respective tensioning element 14 and slidably connected to the support element 10. To open the shading device, the support struts 20 are moved upwards in the direction of arrow 22.

[0023] In the illustrated embodiment, the clamping elements 14 each have a surface element. For this purpose, the clamping elements 14 in the illustrated embodiment are designed such that they have a rectangular frame 24 (Fig. 3) which carries a surface element 26 on one outer side. Of course, other connections between the surface elements 26 and the frame 24 are also possible. Furthermore, in the illustrated embodiment, the corresponding frame 24 is connected to a shading element 18 on each of its outer sides.

[0024] Due to the provision of four surface elements in the illustrated embodiment, a shell element is formed in the closed state, which in the illustrated embodiment has a square cross-section and is therefore cuboid in shape. In particular, together with the square retaining element, the surface elements enclose the support element 10 and thus protect the shading elements, especially from damage.

[0025] In the lower region of the support element 10, this is connected in the illustrated embodiment to a base 30, which additionally includes a base plate 32. In the illustrated embodiment, the base 30 is connected to foldable seating elements 34, which can be folded upwards by 90 degrees from the position shown in Fig. 1 via hinges 36. In the illustrated embodiment, four such seating elements 34 are arranged, so that, together with the surface elements, they each form substantially flat outer surfaces when the seating elements are folded in and the shading device is closed.

[0026] Additionally, it is possible to provide auxiliary devices such as batteries, motors, power connections, radiant heaters, cooling elements, and the like in and / or on the support element 10, the clamping elements 14, and also in or on the base 30. Furthermore, it is preferred that an actuating element for opening and closing the shading device is integrated into the support element 10 (not shown in the drawings for clarity).
