Patent ID: 7775850

Claim:
A water toy comprising: a pedestal portion which includes a pump; a column which is adapted to be fixed to an upper portion of the pedestal portion in such a manner as to extend upwards, which is formed into a circular cylindrical shape, and which includes a water flowing tube in an interior and a water outlet port at an upper end thereof; a spiral water flowing rail which is formed into a spiral shape and which is adapted to be fixed to a circumferential edge of the column; a first water flowing rail which is adapted to be detachably coupled to a lower end of the spiral water flowing rail and which includes a windmill portion having a rotor adapted to be turned by making use of a flow of water; a second water flowing rail which is adapted to be detachably coupled to a lower end of the first water flowing rail while being fixed onto an auxiliary fixing base; a third water flowing rail which is adapted to be detachably coupled to a lower end of the second water flowing rail; a fourth water flowing rail which is adapted to be detachably coupled to a lower end of the third water flowing rail; and a sliding element which is adapted to slide on water flowing surfaces of the respective rails, wherein: the pedestal portion and the auxiliary fixing base have suction cups at a lower end thereof, respectively; the auxiliary fixing base comprises on an upper surface thereof a vacuum fixing button which is connected to an upper end of the suction cup in such a manner as to be operated to create a partial vacuum to hold the suction cup in a fixed place of the water toy; the first water flowing rail has a water flowing surface which is formed substantially into a straight line and comprises a steep sloping portion which slopes steeply from the vicinity of a central portion towards the lower end thereof, a cut-out portion being formed in a portion of the water flowing surface which corresponds to the steep sloping portion, a waterwheel setting portion being provided in a lower portion of the cut-out portion, a plurality of circular projections being provided on a portion of the water flowing surface which lies in the vicinity of the central portion; and the windmill portion has a rotor-driving waterwheel which is set in the waterwheel setting portion and which comprises: a spur gear provided at one end of a center shaft thereof; a drive shaft which comprises at one end a crown gear which meshes with the spur gear provided on the rotor driving waterwheel and a spur gear at the other end thereof; the rotor which comprises a crown gear provided at one end of a center shaft of the rotor in such a manner as to mesh with the spur gear provided on the drive shaft; and a windmill hut which covers the spur gears, the crown gears and the drive shaft, and wherein the rotor and the rotor-driving waterwheel are adapted so that the rotor is turned by the rotor-driving waterwheel which is configured to be turned by a flow of water.
