Definitions

  • the invention relates to a retractor for swimming pool covers with the features listed in the preamble of claim 1.
  • swimming pools are increasingly covered at night and / or on cold days on the water surface with a floating roller shutter or a tarpaulin.
  • the roll-up devices for the roller shutters or the tarpaulin are arranged at an edge of the swimming pool in a box or a pit.
  • a special box disturbs the accessibility of the swimming pool and affects the overall picture.
  • a roll-up device for swimming pool covers (Fr-A-2 385 862) is also known, in which a winding shaft for a tarpaulin is arranged in a shaft at the edge of the swimming pool and is mounted on two swivel arms, so that the winding shaft is in one for rolling up and down the tarpaulin can be raised to a suitable opening position.
  • a separately attached hinged lid enables the shaft to be closed when the winding shaft is swung in.
  • the swivel arms are mounted on pins in the known retractor. With such an arrangement, it is not readily possible to carry out the lifting automatically because the lifting must take place synchronously at both ends in order to avoid heavy loads and damage.
  • the invention is therefore based on the object to provide a retractor for swimming pool covers of the type explained above, in which an automatic lifting can also be carried out synchronously over long periods of time for many actuation processes, even for longer winding shafts, with a robust and compact drive device with regard to severe corrosion loads must be realized.
  • the solution to the problem is specified in claim 1.
  • the torsionally stiff shaft which is to be understood as a shaft that can transmit torques, ensures that the winding shaft is raised evenly at both ends, even if they are very long due to the dimensions of the swimming pool and the automatic lifting device is not on both sides or does not attack evenly.
  • the lifting device can be implemented in a particularly simple manner using at least one bellows cylinder.
  • Such cylinders are known per se. They are operated with the help of compressed air or a hydraulic fluid, especially water.
  • the shaft is expediently covered by a hinged lid which can be pivoted about an axis and which is advantageously fastened to the swivel arms carrying the winding shaft. Then the storage is relatively simple, and the lid is lifted at the same time as the winding shaft.
  • the bellows cylinder acts on the swivel arms in a region between the winding shaft and the torsion shaft.
  • the lid which can be made as a frame construction, is suitably made of stainless material, for example stainless steel. This is important because of the risk of corrosion near a swimming pool. For the same reason, all other parts are also preferably made of corrosion-resistant material.
  • one or more bellows cylinders can be distributed over the length of the winding shaft.
  • a bellows cylinder is provided at the end and in the middle. The torsionally stiff shaft forces the synchronism between the bellows cylinders.
  • the surface of the cover can be adapted to the environment, for example tiled. It is expedient if it is at least partially designed as a grate.
  • a winding shaft 1 is fastened to swivel arms 12 of a cover 3 by means of a bearing block 2 which is only shown schematically and which can assume the two positions shown schematically in FIG. 1.
  • a tarpaulin 4 can be rolled up or unrolled on the shaft 1 to form a roll 5.
  • the winding shaft 1 is expediently driven by a reversible geared motor (not shown).
  • the cover 3 closes a shaft 6 which receives the winding shaft 1, including the winding 5 and storage, arranged under the cover.
  • the cover 3 can be pivoted about a torsionally rigid shaft 7 which is mounted in a frame construction 8.
  • the swivel arms 12 are rotatably connected to the shaft 7.
  • a bellows cylinder 9 with two bellows is arranged in a pit 10 adjoining the shaft 6. With its underside, the bellows cylinder 9 rests on a frame 11 and rests with its top against the swivel arms 12 of the cover 3.
  • three bellows cylinders are provided in the exemplary embodiment, which are arranged at the two ends and in the middle of the cover 3.
  • the number of bellows cylinders, their dimensioning and the The number of bellows per cylinder depends on the length, construction and weight of the cover 3.
  • the torsionally stiff shaft 7 ensures that the bellows cylinders synchronize.
  • a pressure medium in particular water or compressed air
  • the bellows cylinder 9 and the other bellows cylinders by means of a three-way valve.
  • the tarpaulin 4 can then slide or be pulled off the water surface without hindrance.
  • the pressure medium is released from the bellows cylinder 9. The lid then moves under its own weight into the closed position, in which it covers the shaft 6 and the pit 10.
