Definitions

  • This invention relates to swimming pool floors, and in particular to such floors which are movable in the volume of the pool between raised and lowered positions.
  • a swimming pool floor is movable between a lowered position, in which the pool floor lies on or adjacent the base of the pool, and a raised inclined position in which one end of the floor is raised and registers with a fixed pool edge to simulate a beach, and operating means for moving the floor between the raised and lowered positions thereof, the operating means moving the raisable end of the floor upwardly and towards the fixed pool edge so that the raised end of the pool abuts the pool edge in the raised position of the pool floor, the operating means including pivoted links which support the floor from the base.
  • a swimming pool floor according to the invention was designed to be fitted in a pool having a wave machine which propagates waves up the floor towards the raised end thereof.
  • the pivoted links providing a rigid support for the inclined floor, prevent the floor being moved by the action of the waves.
  • the pool In the lowered position of the floor, the pool has almost full depth for conventional swimming, but in the raised position simulates a beach over which waves break when a wave machine is fitted.
  • the operating means may include at least one piston and cylinder device, which is preferably driven by water under pressure to avoid risk of contamination of the water in the pool.
  • the piston and cylinder device is preferably double acting, pressurised water being admitted to one side of the piston to raise the floor and to the other side of the piston to lower the floor.
  • the pivoted links may comprise a pair of links which are pivoted together at respective inner ends, the two outer end of the links being pivoted to the pool base and the floor respectively, the piston and cylinder device being attached to the common pivot point of the links which are pushed to occupy a substantially vertical aligned relationship in the raised position of the floor.
  • the pool has a base 10, one end 12 with a region for a wave machine which propagates waves in the direction of arrow 14, and a fixed edge 16 which adjoins an inclined pool edge surface 18.
  • a movable floor 20 has a frame 22 clad with bouyancy panels 24 (Figure 3) having rectangular grilles 26 for the through passage of water.
  • the floor 20 is moved between a lowered position, in which the floor lies against the base 10, and the raised position illustrated in Figure 1, by two piston and cylinder devices 28 symmetrically positioned across the width of the floor, as illustrated in Figure 2.
  • Each piston and cylinder device 28 is operated by water under pressure, and the piston is connected to the common pivot point 30 of two links 32, 34, which are respectively pivoted to the floor and the base.
  • the cylinder is pivoted at 36 to a bracket fixed to the pool base 10.
  • the force needed by the piston and cylinder devices 28 to lower the floor 20 is merely that required to break the "knee joint" provided by the pivot points 30.
  • the complete floor has a density close to that of water, so minimising the force required to move the floor.
  • Figure 5 shows the lower end of the floor 20 about which the floor pivots in moving between the raised and lowered positions.
  • the lower end ot the floor is received within a recess 38.
  • Rollers 40 mounted on axles projecting from the pool sides are received in elongate slots 42 which accommodate the range of movement as the floor moves.
  • a roller 44 on the end of the floor 20 engages the wall of the recess 38.
  • the surface 18 may be horizontal, instead of being inclined as illustrated, and the floor 20 may have a double inclination, being more steeply inclined adjacent the wave machine and less steeply inclined adjacent the edge 16.
