E N T F E R N E N V O N F L A C H E N W A S S E R S T E L L E N A U F P LÄ T Z E N Considered publications: DT - GM 74 42 207 DT - OS 26 27 444 The invention relates to a drainage device, for removing flat spots on tennis and oport courts, consisting of from a suction roll for sucking up the water, a press roll arranged axially parallel for pressing the water out of the surface, a frame for storing the rollers and a stick-shaped handle for easier handling of the device.

Shallow watering holes that often come after rain or sprinkling of the tennis courts occur, make them unplayable, thereby reducing the degree of utilization and reducing it the return. Therefore one uses different ones to remove the auxiliary materials.

For example, with brooms or nets, the water spots are spread over a larger area distributed over the surface, so that the amount of water that is present can evaporate more quickly and to seep away. This is a very cumbersome process with bad Efficiency.

For others, the places suffer because of the distribution of the water the softened flat surface is often taken away with it.

This means that the next time it rains, the water point will be there Point gets even bigger.

Another method is to soak up the water with flat sponges, to then wring it out again by hand in a suitable place. This method too is cumbersome, laborious and not very effective.

Furthermore, water was removed from tennis courts and sports fields developed a special machine. It essentially consists of one on wheels mounted frame in which there is a large, heavy and rotatable alze, which has an absorbent coating on the surface of the jacket, which is below the roller pushes against the floor of the square. There is also one located axially parallel to this rotatable feed roller, which for the purpose of emptying water continuously against the feed roller presses. The feeding roller is arranged relatively high so that the squeezed out Water can drain into a collecting container also located on the frame.

This solution is also fraught with many shortcomings. Above all the handling of the machine is associated with a considerable amount of force. This results on the one hand from the weight of the machine and the weight of the collected Water and on the other hand, mainly because the press roller is constantly full Pressing force is in function. The unfavorable translation has a particularly negative effect because the large suction roll drives the small press roll through its rotary motion. These negative factors are also fully present where there is little or no water accrues.

furthermore, for functional reasons, the press roller must be quite high in Area of the suction roll can be arranged. This leads to the fact that part of the squeezed water flows back into the suction pad, which has a negative effect on the drainage being affected.

Another shortcoming of the machine is the relatively high cost of acquisition and the bulky dimensions that make it difficult to accommodate.

It is therefore an object of the invention to provide a drainage device create, which are easy to use with good efficiency, low costs and ensures small construction costs.

In a drainage device of the type mentioned This object is achieved in that it is in a frame with a stick-shaped handle a relatively light salt rotatably mounted about its axial axis is located, the is provided with a moisture-absorbing coating on its jacket surface and which can be used with the stick handle to absorb water without any significant effort can roll through shallow water, because in addition to the low rolling resistance and The small weight means that there are no other forces to overcome.

sas emptying of the ... suction roller is done by a stick-shaped one Frame arranged axially parallel to the suction roll in a lever bearing and rotatable there mounted press roll. The rreßkraft between the suction and press roll is applied by hand the lever of the lever bearing is applied according to the nang principle and the requirements continuously adjusted accordingly.

The maximum effort required can be achieved by choosing a suitable Leverage can be kept very small.

Since the press roll is smaller than the suction roll, and for pressing out of the water, the press roller is rotated via a crank transmission, which thereby turn the suction roll turns, there are excellent power ratios, 80 that an effortless drainage is possible.

Neiterhin the dehydration process is improved in that the press roll is located below the suction roll during the dewatering process and so that the water can flow away from the absorbent pad immediately.

% Text see page 8 Another embodiment of the invention sees a hollow press roller with a large number of small openings in the surface of the jacket before, which results in an improved drainage of water during dewatering.

Another embodiment of the invention uses a press roller second suction roll, which at the same time increases the overall suction power of the device and a separate pressure roller is not required.
