  • Patent number: 5213540
    Abstract: An aquatic toy includes a tank containing liquid. The tank includes a bottom part having an upper perforated plate member, a lower guide plate member connected to the upper perforated plate member, and a space formed between the upper perforated plate member and the lower guide plate member. A floatable toy floats on the liquid in the tank. A base is attached to the bottom part of the tank. A liquid propelling unit is provided in the bottom part of the tank which forces the liquid upwards from the space through the upper perforated plate member when it is actuated.

  • Patent number: 5018288
    Abstract: A sound activated toy includes a casing having a lower receiving space and an upper receiving space, a sound activated control circuit disposed inside the lower receiving space, a motor similarly disposed inside the lower receiving space and actuated by the control circuit, and a spout enclosure provided in and communicated with the upper receiving space. The spout enclosure is disposed adjacent to the lower receiving space and has a top wall with at least one spout hole. A propeller assembly is confined inside the spout enclosure. A toy figure mechanism is disposed above the spout enclosure inside the upper receiving space. Both the propeller assembly and the toy figure mechanism are moved by the motor. When a predetermined amount of water is received in the upper receiving space and the control circuit starts to actuate the motor, movement of the propeller assembly forces water from the upper receiving space into the spout enclosure so as to generate a water spout at each spout hole.
