A screen 102 has a pedestal 108 and a screen area 110 on and is a so-called large screen, that is, that its diameter is at least between 10 and 30 meters, but the invention does not relate exclusively to large umbrellas. Rather, the invention can also be applied to any other type of screen or shielding device, in particular for the production of shaded areas. By means of the cooling device 104 becomes a so-called microclimate in the area of the umbrellas 102 affected.

A distance a of two vertical columns 108 in the arrangement 100 is chosen so that a border area 112 the screen surface 110 a screen 102 the arrangement 100 a border area 112 the screen surface 110 an adjacent screen 102 the arrangement 100 overlaps. The distance a corresponds approximately to the diameter of the screen surface 110 but is particularly and preferably slightly smaller than the screen area 110 , The border areas 112 thus form an overlap area 114 in which the screen surfaces 110 a substantially vertical distance 116 between them. About this distance 116 For example, air, which is particularly strongly heated, as indicated by arrow 118 from one area 120 below the screen surfaces 110 in an area 122 above the screen surfaces 110 reach. For this purpose, an effect is used that is similar to the chimney effect. It would be conceivable that the air flow is used for the production of energy, for example by means of unrepresented pneumatic wheels.

A side detail view according to II in 1 the cooling device according to the invention is in 2 shown. This cooler 204 has two fans 206 on, in essence, opposite sides 212 the pedestal 208 a screen 202 are arranged. The fans 206 are by means of a fastening device 214 at the pedestal 208 attached. The fastening device 214 has an axis 216 on which rotates in a fixed with the pedestal 208 connected bearings 218 is included. A rotatable bearing allows the orientation of the fans 206 generated air stream, which creates a cooling effect by the air movement, to a certain area. It is possible the rotational movement of the fans 206 around the axis 216 to prevent after an adjustment of the air flow and / or for example an oscillating movement of the fans 206 around the axis 216 to him witness.

In 3 is one according to line III-III in 2 shown sectional plan view of the inventive arrangement of fans on the pillar of the umbrella. From the 3 is apparent, as the fans 306 the cooling device 304 each by means of the fastening device 314 on the opposite sides 312 the pedestal 308 are attached. The fans 306 are like that on the pillar 308 attached that main exit directions 316 the two fans 306 run in opposite directions. In addition, the fans 306 also on the pedestal 308 attached that main exit directions 316 in each case an angle α between itself and a first center plane 318 the pedestal 308 enclose between them, wherein the angle α has a value of about 65 °.

As already described above, the fans are 306 around the axes 320 rotatable with the pedestal 308 connected. Driven by a drive, not shown, describe the fans 306 an oscillating movement around the axes 320 , The oscillating movement generates a pivoting of the main exit directions 316 by an angle ± β with an amount of about 15 °. The drive for generating the movement, for example, in or on the fastening device 314 be arranged. However, it is also possible, for example, the drive device within the pedestal 308 to arrange and, for example, a common drive device for all on the pedestal 308 arranged fans 306 to use.

An exemplary arrangement 400 of four umbrellas 402 in a substantially square shape is in 4 shown. It can be seen that the four screens are arranged so that each of the first center planes 418 or second middle planes 422 two neighboring umbrellas 402 are aligned approximately congruent to each other, so aligned substantially to each other. By this arrangement as well as the arrangement of the fans 406 in the above-described angle α to the first center plane 418 is advantageously achieved that the main exit directions 416 the fans 406 in the arrangement 400 do not overlap. This is true even if the fans 406 , and thus the main exit directions 416 to perform an oscillating movement. Unwanted turbulence of the individual air streams or other mutual influences of the air streams are thus substantially avoided.

Out 4 are also the overlap areas 414 the screen surfaces 410 seen. By means of the overlapping areas 414 becomes a substantially complete shading of the shielded area 424 reached.

Another possible arrangement of fans 506 on a pedestal 508 according to a further embodiment is in 5 shown. There are four fans in it 506 at an angle γ of about 90 ° to each other aligned with the pedestal 508 a screen 502 but only two in 5 are visible. It should be noted, however, that the 5 Of course, as a representation of only two fans 506 at an angle γ of 90 ° or even three fans 506 can be used, with three fans 506 for example, two fans 506 at an angle 90 ° to each other and the third, not shown fan at an angle between 30 ° and 240 °, in particular at an angle of 135 °, to the other fans 506 can be aligned.

The fans 506 in 5 are also each by means of a fastening device 514 at the pedestal 508 attached. However, this is so that the main exit directions 516 the fans 506 at an angle δ of about 15 ° to a horizontal plane 526 are aligned, ie perpendicular to a central longitudinal axis 528 the pedestal 508 ,

In the 6 shown partially cut plan view according to line VI-VI in 5 of the screen 602 shows the arrangement of four fans 606 at the pedestal, each at an angle δ of 90 ° to the adjacent fan 606 , The fans 606 are also about an axis 626 rotatable on the fastening device 614 attached, so that an oscillating movement by an angle ± β is possible with an amount of about 15 °. The fans are then from a first position 630 in a second position 632 and swung back.

To the not shown drive device (s) for the oscillatory movement of the fans 606 to provide energy are indoors 634 the pedestal 608 supply lines 636 intended. These supply lines 636 may be, for example, electrical, hydraulic or pneumatic lines. However, it is also possible indoors 634 For example, to provide pipes or other components, such as pumps, transformers or the like.

The 7 shows a fan 706 in a partially exploded view. Therein is a fan propeller 740 to recognize, which is shown here only by way of example with three propeller blades. The fan propeller 740 has a fan propeller axis 742 on. The ventilator 706 has a main exit direction 716 on. In main exit direction 716 behind the fan pro propellers 740 is concentric with the fan propeller axis in its air flow 742 a discharge device 744 arranged. The discharge device 740 according to 7 exemplified two concentric and annular pipes 746 on the fan propeller 740 opposite side each with a few nozzle devices 748 are provided. The pipelines 746 are by means of connecting lines 750 connected to each other, with the piping 746 by means of another, in 7 not shown connecting line are connected to a supply line, also not shown. By means of this supply line, not shown, which may be formed for example as a hose and / or pipe, the nozzle devices 748 supplied with a fluid.

This fluid is chosen so that it readily evaporates under the environmental conditions of the screens, for example in the atomized state, wherein the fluid is preferably water. The evaporation of the discharged fluid within the air stream further cools the air flow. It is possible to use the fluid as a carrier liquid for flavorings and / or fragrances, wherein the dosing of the fragrances is then preferably carried out by means of appropriate devices, for example in the interior of the pedestal. The nozzle devices 748 can do this either as atomizer nozzles or as recesses in the pipelines 746 be educated. However, they advantageously allow the fluid to be introduced into the air stream so that it evaporates easily.

In 8th is another embodiment of the screen according to the invention 802 with cooling device 804 shown. In contrast to the embodiments described above, the cooling device 804 in 8th no fans on. Rather, several nozzle devices 848 in a horizontal plane 850 in the pedestal 808 arranged. These nozzle devices 848 are by means of supply devices 852 inside the pedestal 808 are arranged, connected to a water supply. The supply devices 852 have, for example, pipelines 854 and a pump 856 on. The nozzle devices 848 are preferably as in relation to 7 described trained.

The water supply can be, for example, a fresh water supply network and / or a tavern 858 be that under the screen 802 is arranged and collected in the rainwater or the like. This rainwater can be, for example, from the in 8th Shield surface not shown are collected and by means of a pipeline 860 the tavern 858 be supplied. The screen surface can also be equipped, for example, even with solar cells, in particular special flexible solar cells, and / or solar panels. By means of the solar cells then, for example, the pump 856 or operate the fans shown in the other figures.

All embodiments have in common that they influence the microclimate in the area of the umbrellas in such a way that the area shaded by the umbrellas is cooled or felt to be cooled. The cooling takes place by an evaporation process of a fluid, in particular water or the like, which is discharged into the region to be influenced, for example atomized. The cooling can also be effected by generating an airflow generated by the fans in the area under the screens. This creates a cooling on the one hand, that it dissipates evaporating moisture, for example, from the skin of a person in the air flow. On the other hand, a cooling effect is achieved in that the air stream absorbs and removes the body heat emitted by a person in the area of the umbrellas. Of course, a combination of these effects is possible, as for example by the use of a fan according to 7 is reached.
