Description

The invention relates to a device for protection against solar radiation and / or precipitation, with a roof tarpaulin and a frame, the roof tarpaulin forming two opposite transverse sides that extend in a transverse direction of the roof tarpaulin and two longitudinal sides that connect the transverse sides and extend in a longitudinal direction of the roof tarpaulin , wherein a first of the transverse sides has first fastening means for fastening to a substrate and the second of the transverse sides has second fastening means for fastening the roof tarpaulin to the frame such that the frame supports the transverse side fastened thereon at least in a section of the transverse direction of the roof tarpaulin.

Such a device is from the U.S. 9,051,756 B1 known. In this device it is provided that a collapse of the roof tarpaulin, which extends between the frame and the ground, is prevented by the fact that it is oriented in such a way that an air flow (wind) from the second transverse side attached to the frame under the roof tarpaulin flows and this inflates as a result of the attachment of the first transverse side to the substrate.

When using a device according to U.S. 9,051,756 B1 it was found that the roof tarpaulin executes a fluttering movement caused by the air flow, which has a negative impact on the stability of the device and leads to considerable noise development.

The invention was based on the object of such a flutter movement in a device according to the U.S. 9,051,756 B1 to avoid.

This object is achieved by an embodiment of a corresponding device according to the characterizing feature of patent claim 1. Preferred developments of the device according to the invention are the subject matter of the further claims and / or result from the following description of the invention.

According to the invention, a device for protection against solar radiation and / or precipitation is accordingly provided, which comprises at least one roof tarpaulin and a (first) frame, the roof tarpaulin having two at least partially opposite transverse sides and extending in a transverse direction of the roof tarpaulin and two transverse sides connecting and each other forms longitudinal sides extending in a longitudinal direction of the roof tarpaulin. A first of the transverse sides has first fastening means for fastening to a substrate and the second of the transverse sides has second fastening means for fastening the roof tarpaulin to the frame, this fastening of the roof tarpaulin to the frame being designed or provided in such a way that the frame attaches the to it Supports the transverse side at least in a section of the transverse direction of the roof tarpaulin. According to the invention, such a device is further characterized by shortening means for, if necessary, preferably reversible shortening of the free edge length of the longitudinal sides of the roof tarpaulin.

The "edge length" is understood to mean the length of the edge which delimits the material web of the roof tarpaulin on the respective long side. The "free edge length" is then the section of the edge length which, when the roof tarpaulin is spread out in one plane, results as the course of the edge lying in this plane. If the shortening means is not effective, the free edge length can in particular correspond to the actual edge length, while if the shortening means is effective, the free edge length is shorter than the actual edge length.

By shortening the free edge lengths of the long sides, the roof tarpaulin is forced into a curvature along the transverse direction when inflated by an air flow (especially wind), which leads to permanent tensioning of the shortened long sides, which effectively prevents the roof tarpaulin from fluttering.

The shortening means can preferably each comprise two connecting elements (eg straps or (push) buttons) which are arranged at a distance in the longitudinal direction of the roof tarpaulin and which can preferably be detachably connected to one another or are connected. The shortening means can then in particular be used to fix a fold of the respective longitudinal side of the roof tarpaulin, as a result of which part of the edge of the respective longitudinal side forms a loop. This loop-shaped part of the edge is then no longer part of the free edge length of the respective edge.

In order to enable a targeted and, in particular, reproducible folding of the roof tarpaulin on the longitudinal sides, it can preferably be provided that this each forms at least one pocket which ends in the edge of the respective longitudinal side. Such a pocket represents a depression with respect to the adjoining sections of the roof tarpaulin even with ineffective shortening means. This applies in particular if the roof tarpaulin is held taut in such a way that it runs in one plane with the exception of at least the pockets.

In order to enable a targeted outflow of an air flow that has flown over the second transverse side under the roof tarpaulin and thus a secure position of the device even with a relatively strong air flow, it can preferably be provided that the roof tarpaulin has one or more passage openings in the half encompassing the first transverse side. It can furthermore preferably be provided that the passage opening or at least some of the passage openings can be closed, for example by means of a roll-up closure tarpaulin, which, if necessary, can be spread out over one or more of the passage openings and, if necessary, fixed in this extended position to the roof tarpaulin, for example. On the one hand, this enables the passage opening (s) to be closed if necessary, in order to ensure that the roof tarpaulin is safely inflated even with a relatively weak air flow. On the other hand, a closed passage opening also prevents the incidence of solar radiation and / or precipitation, so that the most comprehensive possible protection against it is then given below the roof tarpaulin.

According to a preferred embodiment of a device according to the invention, it can be provided that the roof tarpaulin in a central section third Fastening means for fastening the roof tarpaulin to the first frame or to a second frame in such a way that this frame supports the central section at least in a section of the transverse direction of the roof tarpaulin. This enables the device to be constructed as flexibly as possible, which in particular can also ensure that the roof tarpaulin can be stretched without air flow or when there is no wind. In particular, it can be provided to fasten the first frame in the central section by means of the third fastening means on the roof tarpaulin and thereby stretch it in the transverse direction, while the first transverse side and the second transverse side are fastened to the subsurface via the (first and second) fastening means there become. As a result, the roof tarpaulin is stretched in a tent-like shape, which is stable even without an influx of air. Alternatively, it can also be provided to fasten the second frame in the central section by means of the third fastening means on the roof tarpaulin and to fasten the first transverse side to the substrate by means of the first fastening means there and the second transverse side to the first frame by means of the second fastening means there, whereby a construction of the device is realized which is similar to the one in which the roof tarpaulin is inflated by an air flow which has flowed under the roof tarpaulin via the second transverse side connected to a single frame, but with that connected in the central section to the roof tarpaulin second frame takes over this inflation function of the air flow. As a result, a corresponding structure of the device can also be implemented without air flow.

According to a preferred embodiment of a device according to the invention, it can be provided that the first frame and / or the second frame (if provided) has a cross member and at least one support, which are preferably releasably connectable to one another. Furthermore, it can then be provided that the support has one end with a T-piece, that the cross member comprises two cross member parts, which can each be inserted into an open end of the T-piece and that the second fastening means and / or the third fastening means (if present) two preferably coaxially arranged and from each other comprise spaced-apart tube sections of the roof tarpaulin into which the cross member parts can be inserted. Such a frame is sufficiently stable, easy to assemble and dismantle and, due to only a relatively small number of frame supports, is relatively light and takes up only a small packing volume. This ensures advantageous transport and space-saving storage of the device when not in use.

According to a preferred development of such a device according to the invention, it can also be provided that the ends of the hose sections of the roof tarpaulin located on the transverse sides are closed and that the transverse support parts each have a releasable locking element which is designed to be in a locking position at the adjacent end of the T. -Piece to lie. This enables the roof tarpaulin to be fixed to the frame as soon as the cross member parts of the frame have been pushed into the hose sections of the roof tarpaulin and the open ends of the T-piece and the locking elements are in their locking positions on the corresponding ends of the T-piece. A lateral displacement of the roof tarpaulin relative to the frame, i.e. in the direction of the transverse side of the roof tarpaulin, then prevents the closed ends of the tube sections of the roof tarpaulin. At the same time, the cross member parts of the frame can no longer be pulled out of the T-piece.

The locking elements can furthermore preferably be able to be pressed into a support tube of the respective transverse support part with increasing bias of a spring element, which enables the simplest possible assembly and dismantling of the frame and thus the device.

According to a preferred embodiment of a device according to the invention, it can be provided that the frame and in particular the support of the frame has a preferably disk-shaped holding element that has one or more hooks and / or one or more recesses, in particular in the form of through openings. Such a holding element can in particular in Serve connection with a fastening rope to attach the frame to the substrate. Furthermore, any objects, for example items of clothing, can be hung on such a holding element.

A device according to the invention can furthermore preferably comprise a wall tarpaulin which is set up for attachment to the frame and / or the roof tarpaulin in an orientation extending from the ground in the direction of the roof tarpaulin. The wall tarpaulin can preferably extend from the ground to the roof tarpaulin or end in front of the roof tarpaulin, so that a free space remains between an overhead edge of the wall tarpaulin and the corresponding transverse side of the roof tarpaulin, which, for example, can also serve the purpose of a To allow air flow with the aim of inflating the roof tarpaulin.

According to a preferred embodiment of a device according to the invention, it can be provided that the roof tarpaulin has connecting means on the first transverse side and / or on the second transverse side for connection to connecting means of a particularly identical second device. This makes it possible to use these two devices in combination with one another in order to protect a particularly large area below the two roof tarpaulins, in particular from solar radiation and / or precipitation. By connecting the roof tarpaulins of the two devices to one another, they can also have a particularly stable stand. The invention accordingly also relates to a combination of two such devices.

an inventive device according to an alternative embodiment.

The inventive devices shown in the drawings each comprise a substantially rectangular roof tarpaulin 1 and at least one frame 2, the roof tarpaulin 1 having two opposite transverse sides that extend in a transverse direction of the roof tarpaulin 1 and two transverse sides connecting the transverse sides and extending in a longitudinal direction of the roof tarpaulin 1 forms extending long sides. A first of the transverse sides has first fastening means, for example in the form of in the roof tarpaulin 1 has integrated eyelets or loops, by means of which, for example in connection with appropriate ground anchors, the first transverse side of the roof tarpaulin 1 can be attached to a substrate 3.

The second of the transverse sides comprises second fastening means, by means of which the roof tarpaulin 1 can be fastened to the frame 2 in such a way that the frame 2 supports the second transverse side fastened thereon essentially along the entire transverse direction of the roof tarpaulin 1. These second fastening means comprise two tube sections (not shown) extending in coaxial alignment along the transverse direction of the roof tarpaulin, between which a spacing is provided in a central section with respect to the transverse direction of the roof tarpaulin 1. The ends of these tube sections located on or in the vicinity of the longitudinal sides are closed, while the ends of the tube sections facing one another are designed to be open. To connect the roof tarpaulin 1 to the frame 2 with simultaneous assembly of the frame 2, first two cross member parts 4 of the frame are inserted into one of the tube sections of the roof tarpaulin 1 until they each abut the closed ends of the tube sections. Then a T-piece 5 of the frame 2 is plugged with one of its open ends onto a first (4a) of the cross member 4 and pushed onto this first cross member 4a to such an extent that it is possible to insert the adjacent end of the second cross member 4b into the opposite one insert the open end of the T-piece 5. In order to push the T-piece 5 onto the first transverse support part 4a to such an extent, it is necessary to press a locking element 6 into a support tube 7 of the first transverse support part 4a, which leads to an increasing bias of a spring element (not shown) located inside the support tube 7 (see. Fig. 7 ). As soon as the two cross member parts 4 have been pushed into the respective open ends of the T-piece 5, the first cross member part 4a can be pulled out of the T-piece 5 again to such an extent that the associated locking element 6 is removed from the associated carrier tube 7 due to the pretension of the spring element is moved out and thereby a renewed pushing in of the first transverse support part beyond the locking element 6 4a into the T-piece 5 (cf. Fig. 6 ). This configuration of the frame 2 in combination with the ends of the hose sections that are closed on the longitudinal sides of the roof tarpaulin 1 means that the cross member parts 4 cannot be unintentionally pulled out of the T-piece 5 when the device is installed and, at the same time, that the roof tarpaulin 1 is safe with it the frame 2 is connected.

In the Fig. 1, 2 and 13 It is provided that the devices shown are aligned in such a way that an air flow (wind), each marked by an arrow, flows over the second transverse side connected to the frame 2 under the respective roof tarpaulin 1 and this as a result of the attachment of the first transverse side to the ground 3 inflates so that a free space of sufficient height is provided below the roof tarpaulin 1 to enable one or more people to stay comfortably under the roof tarpaulin 1.

In order to avoid a relatively strong air flow that the roof tarpaulin 1 is so heavily loaded that the holding and support capacity of the frame 2 is exceeded, the roof tarpaulin 1 has a relatively large opening 8 in the half encompassing the first transverse side extends to the first transverse side. In the embodiment according to Fig. 13 In addition to this relatively large passage opening 8, several (specifically three) smaller passage openings 8 arranged in a horizontal row are provided, which can be closed if necessary by means of a closure tarpaulin 9, which is connected to the roof tarpaulin 1 by one of its edges. As a result, an outflow of air flow flowing under the roof tarpaulin 1 can be influenced in a targeted manner and, depending on the strength of the air flow, a reliable inflation of the roof tarpaulin 1 can be achieved and at the same time overloading of the device by the air flow can be avoided.

In order to avoid a fluttering movement of the roof tarpaulin 1 as a result of an air flow flowing under it, the device comprises shortening means 10 for reversibly shortening the free edge length of the longitudinal sides of the roof tarpaulin 1. These shortening means 10 each comprise two connecting means arranged at a distance in the longitudinal direction of the roof tarpaulin 1 in the form of bands 11, which can be connected to one another by a loop or a knot, whereby the roof tarpaulin 1 forms a loop-shaped fold, each of these folds - in the Kind of an edge-side gathering of the roof tarpaulin - a shortening of the free edge length of the long sides of the roof tarpaulin 1 is realized. In order to achieve a visually and functionally advantageous folding of the roof tarpaulin 1 in the area of the two long sides, it forms a pocket 12 on each of the long sides that extends into the edge of the roof tarpaulin 1, these pockets 12 each having pocket surfaces 13. In the embodiment example shown, the straps 11 serving as connecting means are connected to the roof tarpaulin 1 in the area of the pocket surfaces 13.

In the Fig. 2 it is shown that a device according to the invention can also comprise a wall tarpaulin 14, which is intended to be connected to the frame 2 and to the base 3 in an orientation extending from the base 3 to the roof tarpaulin 1. This wall tarpaulin 14 serves, for example, to protect a person behind it from (wind) and from correspondingly oblique solar radiation and oblique precipitation. Because the wall tarpaulin 14 does not extend as far as the roof tarpaulin 1 in the embodiment shown, an air flow can flow under the roof tarpaulin 1 in the intended direction and thus inflate the roof tarpaulin 1 despite the wall tarpaulin 14. Lateral guidance of the wall tarpaulin 14 in the T-shaped frame 2 shown is realized in that a guide rope 15 extends from the free ends of the cross member parts 4 of the frame 2 or from the roof tarpaulin 1 to the substrate 3 on which the wall tarpaulin 14 is attached in each case.

In order to achieve a secure stand of the frame 2 and thus the device as a whole, a support 16 of the frame 2, on the upper end of which the T-piece 5 is attached, comprises an annular disk-shaped holding element 17 (cf. Figures 4 and 5 ), in which several through openings 18 are made. To one or more of the Through openings 18 (each) a fastening cable 19 can be connected, the other end of which can be fastened to the substrate 3 via a ground anchor 20. In addition to this, the holding element 17 can also be used to hang up objects (not shown).

The Fig. 8 and 11 to 13 show alternative types of construction of devices according to the invention which enable the associated roof tarpaulin 1 to be stretched with a sufficiently large free space below the roof tarpaulin 1, in particular even when there is no wind.

With the type of construction according to Fig. 8 the roof tarpaulin 1 is attached to the substrate 3 in the area of the first transverse side as well as the second transverse side, for which the roof tarpaulin 1 in the area of the second transverse side can have corresponding additional fastening means (not shown), for example in the form of eyelets or loops. Furthermore, the roof tarpaulin 1 comprises third fastening means (not shown) in a central section, which can in particular be functionally identical to the second fastening means and which accordingly can also have two tube sections into which the cross member parts 1 of a frame 2 can be inserted. With the type of construction according to Fig. 8 a tent-like stretching of the roof tarpaulin 1 is realized by means of a single frame 2.

With the type of construction according to Fig. 11 on the other hand, the roof tarpaulin 1 is supported by means of a first frame 2a and a second frame 2b, the first frame 2a, as previously based on inter alia Fig. 1, 2 and 11 described, is connected to the second fastening means in the region of the second transverse side, while the second frame 2b, as before with reference to the Fig. 8 described, is connected in a central section of the roof tarpaulin 1 with the third fastening means present there. This type of construction is similar in terms of the stretching of the roof tarpaulin 1 to that according to FIGS Fig. 1, 2 and 13 , ie the second transverse side of the roof tarpaulin 1 supported by the first frame 2a is located well above the subsurface 3. As a result of the support of the central section of the Roof tarpaulin 1 by means of the second frame 2b is also not required to inflate the roof tarpaulin 1 in this way by an air flow.

And in the Fig. 12 it is finally shown how two devices according to the invention can be used in combination with one another in order to again achieve a tent-like stretching of the interconnected roof tarpaulins 1 of the two devices. For this purpose, the two roof tarpaulins 1 are each connected to one another in a central section with an associated frame 2 and in the area of the respective second transverse side by means of connecting means, for which, for example, tapes 11 can be used, which are provided by the additional ones provided on the second transverse sides of the roof tarpaulin 1 Fastening means in the form of eyes or loops can be guided and knotted or connected by means of loops.

The the Figs. 1 to 3 illustrated pockets 12 of the shortening means 10 have a triangular shape in plan view, while the pockets 12 in the embodiments of FIG Figures 8 to 13 are approximately semicircular. It is particularly advantageous if only one continuous band 11 is provided in the area of each semicircular pocket, which is guided in a semicircular sewing of the roof tarpaulin. Pulling together and knotting the two ends of the tape 11 then not only shortens the edges running in the longitudinal direction of the roof tarpaulin, but also shortens them in the transverse direction, reducing the area of the roof tarpaulin and increasing the wind stability.
