Definitions

  • Pool cover systems are known. There are pool cover systems wherein the mechanism for winding and unwinding the pool cover is positioned outside the water, and there are pool cover systems wherein the mechanism for winding and unwinding the pool cover are positioned underwater.
  • the latter known underwater pool cover mechanisms use a stainless-steel tube inside the swimming pool as base for winding and unwinding the slats which cover the swimming pool when unwound.
  • the function of the cover is to cover the swimming pool when it is not in use. It protects the water from evaporation and loss of water as well as insulation to limit heat loss from the water. Another function of the cover is to avoid accidental access to the swimming pool for people, especially young children which could lead to drowning or other injury.
  • cover systems There are several types of cover systems. Most common type is a cover system where a roll of slats is mounted inside the swimming pool under the water level. The activation of the cover system is done by a motor which can be installed outside or inside the swimming pool. The motor is connected to and rotates a cylindrical-shaped element. For easy reading the cylindrical-shaped element is in the present application called "tube".
  • a power cable is connected to the motor at the side of the motor shaft.
  • the power cable is guided from the inside of the swimming pool to the outside. Outside the swimming pool the cable is connected to a connection box which on its turn is connected by another cable to a pool cover controller.
  • the slats are connected the tube.
  • a known arrangement to connect the slats to the tube is by using straps.
  • the straps are fixed at one end to the tube and at the other end to the first slat.
  • the fixation of the straps on the tube is done by using screws and plugs.
  • a number of straps are evenly spaced along the length of the tube.
  • the fixation of the straps to the first slat is done by making slots or holes in the first slat and to loop the strap through the slot of hole in the first slat.
  • the installer need to be cautious when making the slotted holes in the first slat to make sure that it will be aligned with the fixation point of the strap at the other end to the tube. If the slotted holes are not aligned with the fixation points on the tube, then the straps will be wound under an angle when the cover is opened. Further, not aligned fixation might also result in uneven tension between the different straps when pulling on the slats before winding the slats on the tube.
  • Known pool cover mechanisms use tubes which are made of stainless steel.
  • the stainless-steel tube must be of the specific grade 316L, because the tube is permanently installed in the swimming pool wherein the water may be treated with chlorination.
  • a problem however when using stainless steel tubes is that these tubes are very heavy and difficult to carry and handle. Such tubes require at least 2 persons for the installation.
  • the installation of a cover mechanism with a stainless-steel tube is rather complex and requires multiple parts such as metal parts, sealings and different kinds of fixations in order to fix the tube to the side walls of the swimming pool.
  • the supports for holding the tube must be very well aligned and accurately positioned on the pool walls. As the pool walls are not always perfectly parallel, it's time consuming for the installer to make the proper alignment. And, to position the supports accurately, corresponding mounting holes must be made to make sure that both centres of the supports are aligned. Improper installation or misalignment may result in excessive wear of several components including motor, slats, guides, bearing surfaces etc.
  • FIGS. 2A and 2B consist the outer profile of the inner tube 2 of three recessed areas 22 in the outer cylindrical circumference 24.
  • the three recessed areas 22 are separated from each other under an angel of 120°.
  • the three recessed areas 22 of the inner tube 2 match and engage with three protrusions 23 at the inner profile of the outer tube 1.
  • the outside profile of the outer tube 1 has a cylindrical shape 25.
  • the three protrusions 23 are equally spaced over the inside of the outer tube 1.
  • the tube 48 is tilted up to a position where the tube motor side is above the water level of the pool and the tube mechanism assembly 49 is displaced along the shaft portion 35 of the ball joint 16. In this way, the end of tube 48 with the tube motor assembly 47 is beyond the edge 41 of the pool 50.
  • FIGs 9A to 9D illustrate the steps for installing the outer shaft bearing assembly 51 in the second holder 46 which is fixed to a side wall of a swimming pool.
  • the outer shaft bearing assembly 51 connected to tube 48, including the ball joint 16 is the first side to be mounted when installing a pool cover mechanism.
  • the outer shaft bearing assembly 51 is mounted in the holder bottom 11 of the holder 46 by a drop-in assembly.
  • the holder bottom 11 comprises a vertical slot that receives the ball joint housing 17.
  • the vertical slot in the holder bottom 11 is extending horizontally in the direction away from the wall. Therefore, as illustrated in Figure 9B , in a next step the ball joint holder 17 and the ball joint are pulled in the direction of the arrow such that the ball joint holder 17 moves in the horizontal slot.
  • the ball joint holder In this position, the ball joint holder is fixed in the vertical direction by the slot.
  • the holder top 12 can be inserted and snap fit with the holder bottom 11. In this way, the holder top 12 closes also the axial freedom of the ball joint holder 17 in the second holder 46 such that the ball joint holder 17 is now at a fixed position in the second holder 46.
  • the holder top 12 is configured to provide a click sound when the holder top 12 is in the correct position in the holder bottom 11. This is illustrated in Figure 9D .
  • the holder bottom 11 has a vertical slot wherein the motor pin makes a vertical movement when the tube motor assembly 47 is dropped in the holder.
  • the vertical slot is extending in a horizontal slot. Therefore, as illustrated in Figure 10B , in a next step the backlash rubber 13 and the motor 14 are pulled in the direction of the arrow on Figure 10B such that the motor pin 14 moves into the horizontal slot.
  • Figure 10C in a next step the holder top 12 is inserted and snap fit with the holder bottom 11. If the holder top 12 is snap fit in the correct position a click sound is generated by the holder 46. This is illustrated in Figure 10D . The sound provides a confirmation to the installer that holder is correctly closed.
  • FIGs 11 to 14 illustrate how the straps 52 are connected to the slats 55 according to an embodiment not forming part of the invention as claimed.
  • the straps 52 are connected to the slats 55 by means of a slat connector 53 and a buckle 54 (shown in Figure 13 ).
  • the slat connector 53 is a C-shaped tube 57, which can slide over the typical hooks 56 of the slats 55.
  • the hooks 56 can have different shapes.
  • the buckle 54 comprises a main area and two legs 60.
  • the main area is used to hook a loop 61 of the strap.
  • the two legs 60 are located at each side of the main part of the buckle 54 and are used to hook inside the slat connector 53.
  • the buckle 54 is inserted in the slat connector 53 from the slit side 58 (shown on Figure 14 ) of the C-shaped tube 57.
  • One end of the buckle 54 will be pulled through a slot 59 in the slat connector which is at the opposite side of the slit 58.
  • the buckle 54 will be hold in position inside the slat connector 53 by means of the legs 60 of the buckle 54, which remain hooked inside the slat connector.
  • Figure 12A illustrates the first step to assemble a strap 52 to the first slat 55 of the pool cover.
  • a loop 61 of the strap 52 is inserted in the slot 59 of the slat connector 53.
  • the buckle 54 is inserted in the loop 61 of the strap 52.
  • the loop 61 of the strap 52 is pulled inside the slat connector from the slit side 58 of the C-shaped tube 57 towards the slot 59.
