DETAILED DESCRIPTION OF THE INVENTION

(27) An exemplary embodiment of the invention 20 is shown in FIGS. 1-10 and will be seen in FIG. 3 to include: a basin 22; a motor 24; a pump 26; a drive head 28; a mount 30; a light part 32; and a charge part 34.

(28) The basin 22 has an aperture 36.

(29) With reference to FIG. 6, the motor 24 will be seen to have a shaft 38 and, with reference to FIG. 2 and FIG. 6, the pump 26 will be seen to include a housing 40 and a rotor 42. The housing 40 defines: a cavity 44; a pair of outlet ports 46 communicating with the cavity 44; an intake 48 communicating with the cavity 44; and a pin portion 50. The rotor 42 is mounted in the cavity 44 and includes a body part 52 and an impeller part 54.

(30) The drive head 28 comprises a plurality of magnets 56.

(31) With reference to FIG. 8, the mount 30 will be understood to be constructed of translucent plastic and includes a socket portion 58, a receiver portion 60 and a cover portion 62. The receiver portion 60 includes a plurality of receivers 64, a plurality of posts 67 and a platform 69.

(32) The light part 32 includes a circuit board 68, a plurality of lights 70 and a receptacle 72.

(33) The charge part 34 includes a plurality of coils 74. Each coil 74 terminates in a plug 76.

(34) In use:

(35) the cover portion 62 is mounted to the basin 22 to seal the aperture 36;

(36) the basin 22 is filled with water;

(37) the motor 24 is mounted exteriorly of the basin 22;

(38) the drive head 28 is mounted to the shaft 38;

(39) the rotor body part 52 is magnetically attracted to the magnets 56;

(40) the pin portion 50 of the housing 40 is restrained against rotation by the socket portion 58 of the mount 30;

(41) the circuit board 68 is fitted to the platform 69;

(42) the coils 74 are fitted in the receivers 64;

(43) one of the plugs 76 is fitted in the receptacle 72;

(44) rotation of the motor 24 causes rotation of the magnets 56;

(45) rotation of the magnets 56 causes rotation of the rotor body part 52 by induced magnetic fields;

(46) rotation of the rotor body part 52 causes rotation of the impeller part 54 and a voltage differential to be produced in the coils 74;

(47) rotation of the impeller part 54 causes water, that enters the cavity 44 through the intake 48, to be forced through the outlet ports 46;

(48) the coil 74 coupled to the circuit board 68 produces power for the lights 70; and

(49) the basin 22 is illuminated by the lights 70.

(50) The remaining plugs 76 can be coupled to other devices (not shown).

(51) It will be evident that variations of the above are possible.

(52) For example, a variation of the structure shown in FIG. 7 is shown in FIGs. 11A and 11B.

(53) This structure functions is a manner similar to that hereinbefore described, but differs in that the coils are flat coils 74A formed interiorly of a disc 80 which, as indicated by the sequence of FIGS. 14A-C, snap-fits into the cover portion by means of protuberances 82A formed on the periphery of the disc which engage hollows 82B in the cover. The coils terminate in plugs 84A which project from the disc and which, in this variation, engage receptacles 84B formed on a modified light part 32A to provide, in use, for an electrical connection between the coils 74A and the light part 32A; the light part 32A in this variant includes receivers 86A which can engage plug ends 86B of removable cords 88. Only three receivers 86A are shown; it will be understood that one of the flat coils in the disc, when connected, is coupled to the circuit board 68 to produce power for the lights 70; each of the other flat coils is coupled to respective one of the receivers 86A.

(54) An advantage of this structure is that, in contrast to the tubular coils of FIGS. 1-10, wherein a load is borne by the motor whenever the coils are present, irrespective of load, in this structure, the motor only bears a load associated with a coil when the coil is coupled to a load.

(55) Yet another variant is shown in FIGS. 17-21. In this variant, the annular circuit board of FIG. 9-10 is replaced with a plurality of modules 94, each including a plurality of lights 96, a pair of plugs 98 and a clip 100, one of the modules 94A including a circuit board. In use, the clip 100 of each module is secured to one of the posts 67 and the modules are plugged together. This variants functions in a manner similar to the structure of FIGS. 1-16, but has the advantage in that, if the circuit board fails, the defective module(s) can be replaced without removal of the cover portion from the basin, as indicated by FIG. 21.

(56) Other variations are possible.

(57) For example, whereas in FIGS. 11A and 11B, the flat coils appear identical, coils can be varied; finer windings result in more wire length, higher voltages and reduced current whereas coarser windings result in higher current and lower voltage.

(58) Yet further variants are possible. Accordingly, the invention should be understood to be limited only by the accompanying claims, purposively construed.
