BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a moveable covering device, particularly for swimming pools, game areas or the like, and more particularly for average-sized swimming pools such as private swimming pools.
Moveable covering devices for swimming pools are known from U.S. Pat. Nos. 3,854,149 and 3,209,373. The mobility consists in causing the cover itself to move from a position in which it forms a cover over the swimming pool to a position in which the cover forms a shelter from the sun or the rain above a terrace or the like formed in the proximity of the pool.
The structure described in U.S. Pat. No. 3,854,149 is of the pivoting type. The cover is formed of articulated panels. To put the device into the shelter position, it is necessary to install support columns. According to U.S. Pat. No. 3,209,373, the cover itself is supported by pivoting arms. In the shelter position, the structure is unstable, particularly in the presence of a wind.
The Soviet Patent No. 318,237 describes a movable covering device for stadiums. Each cover panel is supported by two swinging arms forming a deformable parallelogram. Such a device is very expensive to produce if good results are required in terms of operational quality, stability, safety and reliability.
The object of the invention is therefore to propose a moveable covering device which is simple, stable and reliable.
SUMMARY OF THE INVENTION
According to the invention, the moveable covering device for swimming pools, game areas or the like, comprising a roof which is moveable between a lowered position in which it covers, in a substantially sealed manner, a first region which may be a swimming pool, game area or similar, and a raised position in which the roof covers, at a certain height, a second region which is offset with respect to the first region, the roof having a first edge on the side nearest the first region and a second edge opposite to the first edge, the device furthermore comprising a structure having an articulation with the ground and an articulation with the roof at a distance from the second edge, and having, starting from the articulation with the ground, a general orientation going from the second region towards the first region when the roof is in the lowered position, is characterised by support means for supporting the roof in the vicinity of the second edge when the roof is in the raised position, the roof being spaced apart from the support means when it is in the lowered position.
The support means can be and preferably are arranged permanently at a certain distance from the first region such as a swimming pool. They are not used when the roof is in the lowered position. In the raised position, the roof is stabilized by the support means. This makes it possible to provide for the roof to be a relatively heavy and/or voluminous assembly, capable of covering a swimming pool or the like having a relative large size, and having, for example, the appearance of a conventional roof. A relatively heavy structure is capable, because of its own weight, of closing in a substantially sealed manner the periphery of the first region when the roof is in the lowered position. It is therefore possible to protect the first region from the intrusion of small animals or insects. If the roof is opaque, the development of algae and other harmful phenomena due to light and in particular due to photosynthesis is prevented.
Preferably, the device comprises means of hoisting the second edge of the roof to its position defined by the support means. It is advantageous for the hoisting means to comprise a winch or the like coupled to a pulling cable extending between the roof and a position close to the support means, in such a way that by pulling on the cable the roof, which is initially in the lowered position, is pulled along a path leading the second edge towards the support means, with a spontaneous pivoting of the pivoting structure also causing the raising of the first edge.
It therefore essentially suffices to operate the hoisting m
