DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION

The present invention refers to a sealed floating cover for swimming pools, which is intended to maintain pool water temperature, reduce the rate of chlorine evaporation from pool water and serve as a barrier protecting from falling into the pool or preventing children from entering the waters pool when it is not in operation.

INTRODUCTION AND PREVIOUS KNOWLEDGE

It is a common practice to heat the water of swimming pools to a specific temperature. When the water surface is exposed to air, the water temperature decreases relatively intensively, therefore, there is a need to apply extra energy in order to maintain the desired temperature of the pool. Furthermore, it is commonly accepted to add chlorine to disinfect the water of bacteria, and it is known that chlorine actively evaporates from water, especially when the latter is exposed to direct sunlight. As well, in many cases, particularly with private swimming pools, there is a fear that children may enter the swimming pool or, God forbid, fall into a swimming pool if they are not taken a proper adult care of. The method and the cover subject matter of the present invention are intended to effectively solve these problems concerning swimming pools and pools of various kinds.

INVENTION DETAILS

The main goal of the present invention is to provide a waterproof flexible floating cover for swimming pools, intended to maintain water temperature in the pool, to reduce the rate of chlorine evaporation from pool water as well as to serve as a barrier from falling into the pool or preventing children from entering the pool when it is not in operation. An additional goal of the present invention is to equip the aforementioned cover with an electric scrolling mechanism. The given references are related to the cover (1) intended for swimming pools, though the word "pool" (100) may refer to all kinds of pools, reservoirs, open containers, closed containers and various things containing water or other liquids.

The sealed cover (1) for swimming pools is made of a flexible waterproof bottom sheet (2), a flexible waterproof upper sheet (3) and several rods made of foam material (4). The flexible waterproof sheets (2) and (3) are made of waterproof flexible material, such as PVC and the like. The rods (4) are made of foam materials of law specific weight that able to float on the water. For instance, polyethylene is foamy and has a low degree of density, which makes it easy to float on water surface and usable as thermal insulation.

Preparation and manufacturing of the sealed cover (1) can also teaches its structure the. First, we prepare a pair of flexible sealed sheets of the desired size and matching the size of the pool the cover is intended for. These pair of sheets is in fact the bottom and the upper sheets (2) (3). At the second step, we put the first sheet on the second one in parallel. At the third step, we weld together three sides (a) (b) (c) of the pair of sheets so that they become as one unit with open side (d). After that, we weld sheets (2) and (3) in lines (5) that creates closed sleeves (6) that their opening (61) ends in the open side (d). Obviously, it is possible to weld the lines (5) and afterwards the sides (a) (b) (c). At the fourth step, inserting the rods (4) into the sleeves (6) via the openings (61) and then welding the openings (61). The structure of the cover (1): from the above explanation how to make the cover (1) it is understood that the cover (1) comprises a bottom and a upper sheets (2) (3) which are welded together in four sides (a) (b) (c) (d) and that these sheets include several hollow sleeves (6) in which the rods (4) are inserted. It is desirable and possible that the width of the each sleeve (6) will be about 20 cm, although the invention can be applied to various sizes.

Using the cover (1): The cover (1) is lightweight in relation to its volume. An average person can alone cover a pool by the cover (1) and to unfold the cover (1) after use, and also to carry the cover to the edge of the pool and unfold it on the surface of the pool water. The sleeves (6) are sealed, so that the water does not get inside. If the sleeves were not sealed, the weight of the cover (6) would be very high, which could be harmful for its expected form/shape, and above that, make it impossible for an average person to remove the cover from the pool before using the pool without assistance.

Effective use of the cover (1): the cover serves as a thermal insulator, prevent direct sunlight and can also prevent children from entering the pool without a proper adult care. As above mentioned, the rods (4) are made of a foam material with insulating characteristic, so that the cover (1) can serve as a good and effective thermal insulator. This feature of the cover (1) reduces the amount of energy necessary for heating the water pool. I addition, the cover (1) blocks a direct sunlight to the water, so that the pool water is covered, and reduces the level of chlorine evaporation from the pool water. It is true both for swimming pools and for purification pools and for other pools, when it is customary to add sanitation materials to the water. In addition, a child of an average weight can walk on the cover (1) lying on the surface of the pool while the cover (1) remains stable and does not let the child fall into the water. It is important to emphasize that, despite all features of the invention, the cover (1) will not replace a proper adult care of children or stop them from entering the pool at the time they are not supposed to do it. The cover (1) only provides extra protection. The cover (1) can be combined with a scrolling mechanism (200), which includes a scrolling rod (201) and an engine (202) that can be an electric engine, intended for work in water environment.

Fig. 1 describes the cover, which covers a surface of a swimming pool (100), combined with the scrolling mechanism (200). Fig. 2 describes the cover (1), whereby side d remains open and allows the rods (4) to be inserted into the sleeves (6).

Rigid rods (7) for stabilizing the cover (1): the cover (1) can include a rigid rod (7) in each of said sleeves (6) or in part of them. The rigid rods (7) are made of a low specific weight hard material, for example, a fiberglass. If an adult person is standing on the edge of the cover (1) when the cover covers the pool, the edges of the cover do not plunge into the water. This is because the weight of the same person is "spread" along the length of the sleeves and the rigid rods and thus prevents the cover from sinking. Fig. 3 describes a part of the cover (1), whereby the sleeves (6) include a rigid rod (7)

Strengthening canal (7) for stabilizing the cover (1): the cover (1) can include a Strengthening canal (8) in each of said sleeves (6) or in part of them. The strengthening canals (8) are made of a low specific weight hard material, for example, plastic or fiberglass. If an adult person is standing on the edge of the cover (1) when the cover covers the pool, the edges of the cover do not plunge into the water. This is because the weight of the same person is "spread" along the length of the sleeves and the strengthening canals and thus prevents the cover from sinking. The strengthening canal (8) are designed as a long open profile as depicted for example in Fig. 4. Fig. 5 depicts the strengthening canal (8) wherein in it located the rods (4). Fig. 6 describes a part of the cover (1), whereby the sleeves (6) include strengthening canals (8)
