Definitions

  • the present invention relates to a system for covering a swimming pool, of the known type comprising:
  • the device for winding the traction cords of the sheet consists of a single winding roller, placed adjacent to one of the two ends of the winding drum of the sheet, and including two separate sections for winding the two cords.
  • This arrangement involves the need to provide a system for guiding the return branches of the two traction cords, configured for returning both cords to said single winding roller. Since the forward branches of the two cords run along the two sides of the swimming pool, one of these cords is located on the opposite side to that in which the winding roller of the cords is located, which forces the use of a relatively complex return system of the cords.
  • a system for covering a swimming pool of the type indicated in the preamble of claim 1 is known from US 2 958 083 A . Similar covers are also known from EP 0 142 977 A , US 3 418 667 A , FR 2 908 402 A1 and US 3 885 255 A .
  • the object of the present invention is to provide a covering system, which is at the same time simpler in construction and more reliable in operation than the known system described above.
  • Another object of the invention is to provide a covering system that does not require a complex control system of the two motors that control the rotation of the winding drum of the sheet and of the device for winding the traction cords of the sheet.
  • the invention relates to a system for covering a swimming pool having the characteristics of claim 1.
  • each of the two traction cords of the sheet has its return branch that extends along a respective side of the swimming pool and ends at the respective winding wheel, located on the same side. This considerably simplifies the guiding system of the traction cords with respect to the known system which was mentioned in the preceding description, and also makes it easier and more reliable to check the operation of the device.
  • the system comprises a controller of said first motor and of said second motor which is programmed for:
  • the aforesaid controller is also programmed to place the second motor in a neutral condition when the first motor is active, and to place the first motor in a neutral condition when the second motor is active.
  • the two motors are hydraulic motors and the aforesaid neutral condition of each motor is a condition wherein the motor is made freely rotatable, by direct connection of the inlet and outlet for the hydraulic fluid in the motor.
  • the reference number 1 indicates - in its entirety - a system for covering the reservoir S of a swimming pool (visible in Figure 7 ).
  • the system 1 includes a sheet T which can be rolled around a winding drum D (see in particular Figures 3 and 6 ).
  • the sheet T is wound around the drum D when it is necessary to uncover the pool, while it is unwound from the drum D when it is necessary to cover the pool.
  • the winding and unwinding movements of the sheet T are controlled by a motorized unit which is indicated - in its entirety - by the reference 2 in Figures 3-6 .
  • the motorized unit 2 is placed within a pit 3 (see also Figure 7 ) arranged near one end of the reservoir S of the swimming pool.
  • the sheet T has a first end edge associated with the drum D by means of fastening means of any known type.
  • each side edge of the sheet T is in the form of a rope 14.
  • each guide G comprises two parallel channels.
  • the respective side rope 14 of the sheet slides in the channel closest to the pool reservoir. This channel communicates with a narrow slot leading to the inner side of the guide G, to allow the passage of the sheet T.
  • the reduced height of the slot with respect to the diameter of the side rope 14 safely prevents the rope 14 from slipping away from the guide G in a transverse direction to the guide.
  • each traction cord C is arranged on the extension of a respective side rope of the sheet.
  • Each cord C is engaged on return wheels 4 freely rotatable around stationary axes, so as to present a forward branch C1, which extends longitudinally on the extension of the respective side rope 14 of the sheet T, (see Figures 7, 8 ) and a return branch C2, which extends longitudinally on the same side of the pool up to a respective winding wheel R.
  • the system according to the invention has two separate wheels R, for winding the two traction cords C for pulling the sheet, which are mounted coaxially with the drum D for winding the sheet, adjacent to the two opposite ends of the sheet.
  • each of the wheels R is connected in rotation with a central shaft 5, which is supported in rotation around a horizontal axis 6, by means of rolling bearings 7, from the upper ends of two stationary support columns 8.
  • each wheel R for winding the respective cord C comprises a hub 9 connected in rotation with the central shaft 5 and two parallel and spaced apart discs 10 which define between them the space for containing the turns of the respective traction cord C (which therefore winds in a spiral within the aforesaid space defined between the discs 10 of the wheel R).
  • the drum D for winding the sheet comprises a cylindrical body 11 rotatably mounted by means of rolling bearings 12 over the central shaft 5, in such a way that the winding wheels R of the cords C, and the winding drum D of the sheet T, are free to rotate independently.
  • two discs 13 are mounted at the ends of the cylindrical body 11 for containing the turns of the sheet T.
  • Figure 6 also illustrates the section of the sheet, with the two side edges forming the two ropes 14, which are intended to be retained and guided within the stationary guides G arranged along the two side edges of the swimming pool ( Figures 7, 8 ).
  • the unit 2 comprises a first hydraulic motor M1 for driving the drum D for winding the sheet T, and a second hydraulic motor M2 for controlling the rotation of the wheels R for winding the traction cords C.
  • Both the motors M1 and M2 are hydraulic motors each having an inlet 15 and an outlet 16 for the hydraulic fluid, as well as a control unit 17 including a unit of solenoid valves for controlling the aforesaid inlets and outlets.
  • the motor M2 is mounted coaxially to the central shaft 5 and has an outlet shaft 18 which is connected in rotation with the shaft 5 by means of a joint 19 of any known type.
  • the motor M1 is mounted with its axis arranged parallel and spaced apart from the axis of the motor M2 and controls the rotation of a gear 20 (see Figure 3 ) connected by a chain H with a gear 21 connected in rotation with the drum D for winding the sheet.
  • the system also includes a return roller 22 which guides the sheet T leaving the winding drum D, and which is mounted freely rotatable at its ends on supports 23 ( Figure 3 ).
  • the control unit 17 for the motors M1, M2 is, in turn, controlled by an electronic controller E which is programmed for:
  • the controller E maintains the motor M2 in a neutral condition when the motor M1 is activated and keeps the motor M1 in a neutral condition when the motor M2 is activated.
  • the "neutral condition" of the motor means a condition in which the motor is freely rotatable and/or is disconnected from its driven shaft.
  • the neutral condition of the motor corresponds to a condition in which the hydraulic inlet and outlet of the motor are connected directly to each other, so that the motor is freely rotatable.
  • the neutral condition could, for example, be the condition in which the electric motor is decoupled from its controlled member, by opening an electrically-operated clutch.
  • the M2 motor is activated so as to wind the traction cords C over the two wheels R.
  • the cords C pull the sheet T over the reservoir S, making it unwind from the drum D.
  • the motor M1 is in its neutral condition, so that the drum D is able to rotate freely, following unwinding of the sheet T caused by the traction exerted by the cords C.
  • the ropes 14 constituting the side edges of the sheet T are guided within the stationary guides G arranged along the two sides of the swimming pool and are retained within these guides, so as to ensure complete safety of the cover even in the case of applying a heavy weight above the sheet.
  • the motor M1 When it is necessary to uncover the pool, the motor M1 is activated, so as to rotate the drum D in the winding direction of the sheet T, while the motor M2 is placed in its neutral condition, so that the wheels R with the central shaft 5 that connects them are able to rotate freely following the unwinding of the cords C by the wheels R, which is caused by winding the sheet T around the drum D.
  • each traction cord C has its return branch C2, which runs on one side of the pool and winds on a wheel R located on the same side, which considerably simplifies the guiding system of the traction cords with respect to the known solution that was discussed at the beginning of the present description.
  • the aforesaid greater simplicity of the guiding system of the traction cords C also determines a lower complexity and greater reliability of the rotation control system of the winding drum D and of the wheels R for winding the traction cords.
