Definitions

  • the technical sector of the invention is that of mechanical or electro-mechanical devices for covering and discovering a space of substantially rectangular, or square shape and in particular a swimming pool by means of a flexible retractable cover.
  • Polyvinyl chloride (PVC) or other synthetic materials are also known to be flexible covers, the installation or removal of which is done manually. Unfortunately, it must be noted that this daily work is quickly considered to be tiresome and it is therefore quickly abandoned.
  • the invention therefore aims to provide a simple device, inexpensive and easy to use which would solve the problem of covering swimming pools and similar places while avoiding the drawbacks of the above devices.
  • the invention relates to a device for covering a free space, in particular a swimming pool, which comprises in combination at least one flexible cover comprising a guide means at least one means of traction secured to the first end of the cover, at least one means for fixing the stretched cover, and at least one means for returning the cover to the folded position, this return means being situated on the side of the second end of the cover.
  • the guiding means can be constituted in one embodiment, by guide rollers arranged sliding on two tensioning cables moving in two slides located along the longitudinal edges of the space to be covered.
  • the traction means may consist of a rigid bar disposed laterally and integral with the first end of the cover, and by a pull cord while the tensioning cables of the cover have one end fixed to the pull bar, the opposite end being secured to the return means of the cover.
  • the device may comprise, on the side opposite to the return means, a means for assisting in the traction of the cables.
  • the traction torque of the assistance means is lower than that of the cover return means.
  • the cover return means consists of two spiral springs secured at one end, tensioning cables and at the other end, a fixed reference point.
  • the return means consists of at least one elastomer axis with a high coefficient of torsion comprising a fixed end and an end secured to the tensioning cable on which it is wound, the tension of the cable causing the torsion of the axis and creating the return torque of the cover.
  • the return means consists of an electric motor supplied at low voltage, the output shaft of which is integral with a cover winding drum, the motor being able to be disengaged from the winding shaft during the tensioning of the cover and during the time when the free space must be covered.
  • the slides can have a cylindrical tubular shape provided with a longitudinal slot for the passage of fixing axes of the cover on the tensioning cable, while the guide rollers of the cover will have a shape spherical pierced with a bore in which is provided the fixing axis of the cover, one end of this axis being slidably mounted on the tensioning cable and the other end being fixed to an eyelet of the cover through the longitudinal slot of the slide.
  • the simplest embodiment comprises a flexible cover 1 mounted on axes 2, the precise arrangement of which will be explained below; two longitudinal slides 3, 3 'for guiding the cover 1, which itself carries a traction means constituted by a bar 4 fixed to the free end of the cover and to which a traction cord 5 can be linked .
  • the device also comprises a means of fixing the stretched cover which may consist of two supports 6,6 'in the shape of a "U” arranged on the end of the pool opposite to the place of storage of the cover, supports in which come to dispose the ends of the drawbar after full coverage of the pool.
  • the return means may comprise a latching device which prevents the return to the storage position of the blanket and thus constitutes a means of fixing the stretched blanket, this variant being used in particular when it is desired have a self-floating cover on the pool basin.
  • the latching device can be disengaged so that the return means can play its role during the folding of the cover.
  • the device comprises a means for returning the cover to the opening, this return means being here constituted by two reels 7,7 ', with spiral spring.
  • the slides 3 and 3 ' (see Figures 3 and 4) have a cylindrical tubular shape and have a longitudinal slot 8 through which pass the axes 2 for fixing the cover.
  • Inside the slides 3.3 ′ passes a traction cable 9, one end of which is fixed by means of a plastic end piece 10 to the traction bar 4 and the other end of which is wound on the return means of the cover.
  • This is slidably mounted on the cables 9 by means of the eyelets 11 of the fixing pins 2, the latter supporting spherical guide rollers disposed inside the slides 3, 3 ', the pins 2 being themselves fixed on cover with eyelets 13.
  • the bar is released from the supports 6 or from the snap-fastening and the reels 7, 7 ′, which had been compressed by the tension of the cables 9, are relaxed by pulling on them.
  • the bar 4 being recalled back drives with it the axes 2 which slide on the cables 9, and thereby fold the cover in accordion.
  • the reels in another variant, can also be integral in rotation with a tubular winding axis, in which case the cover can be rolled up instead of folding in accordion.
  • the device may include a means of traction assistance.
  • This can be constituted by a second pair of reels 14,14 'arranged on the side of the pool which carries the "U" supports.
  • the cables 9.9 ′ are then fixed, in addition to the bar 4, to these reels 14, 14 ′.
  • the winders 14,14 ' may have a lower stiffness than that of the return means 7,7' - On closing, the traction of the cables 9 is then helped by the tension of the winders 14,14 '.
  • the return means may consist of at least one elastomer axis with a high coefficient of torsion, one fixed end of which is secured to the edge of the swimming pool and the other end of which is secured to the tensioning cable.
  • This elastomer shaft can be located inside a drum around which the cover is wound at rest, the shaft then being secured by one end of the winding drum.
  • the axis twists on itself and creates a return torque which will be used when the pool is opened to return the cover to its rest position.
  • the return means is constituted by an electric motor 15 supplied with low voltage and whose output shaft, disengageable, rotates the winding drum of the cover if there is one one, or the reels of the tensioning cables, if this solution has been chosen.
  • a cover 16 disposed above the axis of the reels makes it possible to store the cover with maximum discretion and ensuring protection against external damage.
  • the box 17 for storing the folded or rolled up cover can be located outside the right-of-way of the swimming pool.
  • the slides 3 and 3 '( Figure 8) will take a bent shape 18 and will pass above the coping 19 of the pool.
  • This solution can be advantageous in particular in the case where the return means consists of an electric motor which must be distant from the vicinity of the pool water.
  • the cover can be fixed directly to a winding drum, without the presence of a slide being essential since the cover moves on the surface of the water.
  • the two covers can then be attached to the same reel and unrolled together.
  • a protection 23 (FIGS. 10 and 11). This can be articulated and include a horizontal part 23a fixed and a second part 23b, articulated on the first and rising (figure 11) during the course of the cover.
  • the invention has the fundamental advantage of its simplicity of use which allows it to be used daily without fatigue, which the prior devices did not allow.
  • the invention applies, in addition to the coverage of swimming pools to that of all enclosed spaces, for which coverage would be necessary, such as terraces, courtyards and balconies.
