Description

[0001] Shading device

[0002] Technical area

[0003] The invention relates to a shading device with at least one sun sail and with at least one winding device provided for winding and unwinding the sun sail, which winding device has a rope along one side or a diagonal of the sun sail, which rope is connected in a rotationally fixed manner to the sun sail which can be wound and unwound thereon.

[0004] State of the art

[0005] Shading devices with winding devices are known from the prior art (WO2018162606A1), which are designed in the manner of a roller reefing system for winding and unwinding a sun sail. For this purpose, the winding device has a rope that is stretched along a diagonal of the sun sail and is connected to the sun sail by sewing in a rotationally fixed manner. By operating a jib furler of the winding device, the rope is rotated, and thus the sun sail is either wound up or unwound from the rope. If the sun sail of the shading device needs to be replaced, for example due to a change in size or damage, the seam between the rope and the sun sail must be undone, which can often be relatively complex.

[0006] Description of the invention

[0007] Based on the prior art described above, the invention therefore sets itself the task of facilitating the interchangeability of a shading device with a sun sail that can be wound up and unwound on a rope. Furthermore, this shading device should be structurally simple and stable.

[0008] The invention solves the problem by the features of claim 1.

[0009] If the shading device has several clamps distributed along the length of the side or diagonal of the awning, a rotationally fixed connection between the rope and the awning can be achieved. The awning is thus firmly attached to the rope. The clamps each have a receptacle and at least one clamping element on the receptacle. This clamp holds the rope and the awning together under a compression that can be adjusted using the clamping element, thus detachably and rotationally fixedly connecting them.

[0010] In this way, the frictional connection between the rope and the awning can be released by loosening the crimp, allowing them to be separated. This makes the awning easy to remove from the shading device—for example, for repair, replacement, resizing, or maintenance.

[0011] In addition, the clamping element allows for adjustable compression, making the torsion-resistant connection not only easy to handle but also allowing it to be adjusted according to design specifications. The shading device is therefore adaptable to awnings of various sizes, making it comparatively flexible in its application.

[0012] A particularly stable, torsion-resistant connection between the rope and the awning can be created, for example, if the clamping element is directly in contact with the awning

[0013] Preferably, the clamping element is arranged on the receptacle so that it can move toward and away from the rope, thereby generating a high pressing force between the rope and the awning. The design can be further simplified if the clamp has a base body with two opposing legs and a web connecting these legs, which (two legs and the web) form the receptacle between them. The base body can preferably have an open profile shape, in particular a U-profile.

[0014] The above can be further improved if the opposing legs are straight and parallel and / or the bridge is concave.

[0015] If the clamping element is provided on one leg, this can make the clamp easier to handle and also the installation of the shading device.

[0016] For example, the stability of the rotationally fixed connection can be further increased if each leg has one, in particular two, clamping elements, with two clamping elements on each leg being directly opposite each other.

[0017] Constructive simplicity can be achieved, for example, if the clamping element is formed by a clamping screw.

[0018] The strength of the connection between the awning and the rope can be increased if the awning has a hemstitch along its side or diagonal, in which the rope runs at least in sections.

[0019] The above can be further improved if the sun sail has a flexible surface element and at least one band attached to the flexible surface element, in particular sewn to it, which forms the hemstitch at least in sections. The band can be a webbing, for example. A particularly crease-free winding and unwinding of the sun sail from the rope can be achieved, for example, by having at most the band of the sun sail run along the mount.

[0020] For example, a hemstitch can be created when the surface element and band are formed.

[0021] It is also conceivable that the hemstitch is formed by a loop of the sewn-together ribbon.

[0022] For example, the rope is designed to be torsionally stiff or low-torsion to facilitate crease-free winding and unwinding of the sun sail.

[0023] It is conceivable that the rope could be designed as a cable, particularly a fiber rope, which can further increase the stability of the shading device. Preferably, the fiber rope has a core-sheath braid with a polyester sheath braid and an HPPE (High Performance Polyethylene) core braid, which can ensure particularly stable rope construction.

[0024] Improved stability in the torsion-proof connection between the awning and the rope can be achieved if the clamps are distributed over the length of the side or the length of the diagonal of the awning at, in particular, the same distance from each other.

[0025] Compact dimensions can be achieved, for example, if the clamp has a U-shaped cross-section. A U-shaped clamp can also be advantageously wound and unwound on a rope along with the awning. For this purpose, the clamp can have a U-profile, for example. The clamp can also be elongated.

[0026] The awning and rope can be advantageously held together by the clamp and held together with a force fit, for example, if the receptacle has a U-shaped cross-section. Preferably, the clamping element, with its clamping surface, is positioned essentially—i.e., more than 50%—in the half of the rope facing away from the ground, as seen from the base of the receptacle. This prevents the rope from being pulled out of the receptacle, which can make the torsion-resistant connection between the awning and rope more stable.

[0027] Short description of the drawing

[0028] The figures show, for example, the subject matter of the invention in more detail using several embodiments.

[0029] Fig. 1 is a plan view of a shading device according to a first embodiment,

[0030] Fig. 2 is a fragmentary side view of the shading device shown in Fig. 1,

[0031] Fig. 3 is a sectional view according to III-III of Fig. 2 and

[0032] Fig. 4 is a fragmentary sectional view of Fig. 3, but with a differently designed sun sail according to a second embodiment.

[0033] Ways to implement the invention

[0034] According to Fig. 1, for example, a shading device 1 with a substantially four-sided sun sail 2 and a winding device 3 is shown.

[0035] The winding device 3 serves to wind up and unwind the sun sail 2, which can be tensioned via tensioning cables 4, which engage opposite corners of the sun sail 2, a tensioning device not shown in detail.

[0036] In the exemplary embodiment, the winding device 3 is designed in the manner of a furling system and for this purpose has a jib furler 5 and a halyard swivel 6, between which a rope 7 is stretched, which can be subjected to a direction of rotation 8 via the jib furler 5. Since the rope 7 running along a diagonal 9b of the sun sail 2 is connected to the sun sail 2 in a rotationally fixed manner, the sun sail 2 can be wound up or unwound by the winding device 3 depending on the direction of rotation 8 of the opposite directions of rotation.

[0037] The rope 7 is designed to be torsionally rigid or low-torsion and exhibits no or hardly any torsion or high torsional rigidity in the directions of rotation 8 – which essentially prevents the sun sail 2 from twisting relative to the rope 7. It is generally mentioned that such a rope 7 can be a fiber rope with a core-sheath braid in order to ensure high torsional rigidity. For example, such fiber ropes are used as luff lines for a headsail, gennaker, etc. Preferably, such a torsionally rigid or low-torsion fiber rope with a core-sheath braid can, for example, have a polyester sheath braid and an HPPE (High Performance Polyethylene) core braid. The rope 7 has, for example, a round cross-section, as shown in Figures 3 and 4.

[0038] In Fig. 1, it is also indicated by dashed lines that the rope 7 can also be provided running along one side 9a of the awning 2. Apart from the lateral run, this design variant is structurally identical to the diagonal run. Here, too, the rope 7 is connected to the awning 2 in a rotationally fixed manner.

[0039] According to the invention, this rotationally fixed connection between the sun sail 2 and the rope 7 is formed by several clamps 10 of the shading device 1, namely five as shown in Fig. 1, for example.

[0040] These clamps 10 are distributed over the length L of the diagonal 9b of the sun sail 2. In the embodiment according to Fig. 1, the clamps 10 are arranged at a distance from one another, which distances are essentially equal. It is conceivable that at least one clamp 10 is arranged in the area of ​​the beginning, the end, and the middle of the diagonal 9b of the sun sail 2. The clamps 10 connect the rope 7 and the sun sail 2 to one another in a force-fitting manner. All clamps 10 have a receptacle 11 and at least one clamping element 12a, 12b on the receptacle 11 - as can be seen in Figures 3 and 4. The rope 7 and the sun sail 2 run together in each receptacle 11 of the clamps 10. These are detachably and rotationally fixedly connected to one another in the receptacle 11 by means of clamping elements 12a, 12b with adjustable compression. This creates a particularly stable, torsion-resistant connection between rope 7 and awning 2, which torsion-resistant connection is also detachable.This allows the rope 7 and the awning 2 to be separated from each other. This not only facilitates maintenance work but also facilitates the replacement of the awning 2 or the rope 7. It also allows the size of the awning 2 to be changed or the awning 2 to be repaired – all without having to remove the rope 7 from the shading device 1.

[0041] As can be seen from Figures 3 and 4, the clamping element 12a, 12b rests directly on the awning 2. The clamping element 12a, 12b is arranged on the holder 11 so that it can be moved towards and away from the rope 7 in order to advantageously adjust the pressing of the awning 2 and the rope 7 according to the requirements for a rotationally fixed connection. For this purpose, the longitudinal axis A of the clamping element 12a, 12b is directed towards the rope 7 in the holder 11. As shown in Figures 3 and 4, the longitudinal axis A corresponds to the axis of rotation of the clamping element 12a, 12b designed as a clamping screw. The clamping element 12a, 12b can therefore be rotated in the direction of the rope 7. For this purpose, the clamping element 12a, 12b has a head suitable for attaching a tool.

[0042] All clamps 10 are identical and have a U-shaped cross-section. Thus, the clamp 10 has a base body 13 with two opposing legs 13a, 13b and a web 13c connecting these legs 13a, 13b. The receptacle 11 is formed between the legs 13a, 13b and the web 13c. Figures 3 and 4 also show that the opposing legs 13a, 13b run straight and parallel to one another, and the web 13c is concave, resulting in a U-shaped receptacle 11 on the clamp 10. The base body 13 is, for example, mirror-symmetrical. In the exemplary embodiments, the base body 13 has a U-shaped profile. For example, the base body is made of metal, in particular stainless steel.

[0043] All clamping elements 12a, 12b are provided on the legs 13a, 13b, with each leg 13a, 13b having two clamping elements 12a, 12b, as can be seen in Figures 2 to 4. The clamp 10 thus has four clamping elements 12a, 12b. Two clamping elements 12a, 12b on each leg 13a, 13b are located directly opposite each other. This allows the rope 7 to be held centrally in the receptacle 11 by the clamp 10 on the awning 2 in a rotationally fixed manner, which facilitates the crease-free winding and unwinding of the awning 2 from the rope 7.

[0044] The awning 2 has a hemstitch 14 along its diagonal 9b, through which the rope 7 runs - as can be seen in Figures 3 and 4. The hemstitch 14 protects the rope 7 on the one hand - and can also create a particularly stable rotation lock of the rope 7 on the awning 2.

[0045] For this hemstitch 14, the awning 2 comprises not only a flexible surface element 2a but also a band 2b, which is sewn to the flexible surface element 2a via two parallel longitudinal seams 15. The band 2b is designed as a mechanically resilient webbing.

[0046] As can be seen in Figures 3 and 4, at most the band 2b of the sun sail 2 runs adjacent to the holder 11, which enables the flexible surface element 2a to be wound up and unwound more crease-free.

[0047] The band 2b forms the hemstitch 14 at least in sections.

[0048] As shown in Fig. 3 according to a first embodiment, this hemstitch 14 is formed by the band 2b and the surface element 2a. As shown in Fig. 4 according to a second embodiment, this hemstitch 14 is formed by a loop 16 of the band 2b and the surface element 2a. This loop 16 is formed by a seam 17, namely a longitudinal seam, which sews the band 2b itself together.

[0049] Furthermore, it can be seen in Figures 3 and 4 that all clamping elements 12a, 12b with their clamping surface K, as seen from the bottom 11a of the receptacle 11, are arranged essentially, namely more than 90%, in the half 7a of the rope 7 facing away from the bottom 11a. This reliably holds the rope 7 in the receptacle 11.

[0050] In general, it is noted that "in particular" can be translated into English as "more particularly." A feature preceded by "in particular" is to be considered an optional feature that can be omitted and thus does not constitute a limitation, for example, of the claims. The same applies to "vorzugsweise," translated into English as "preferably."
