Abstract
A toy fish drive causes one or more toy fish to swim in a natural fashion in a transparent aquarium (viewing tank). A magnetic drive is connected to the external side of the wall or bottom portion of the aquarium and is supported from the side. The drive has two opposite sets of magnets which are rotated to exert magnetic drive forces on a swimming toy fish in the tank, the toy fish containing a magnet and swimming at a selected sinking rate. By means of the attracting force of the magnet in the toy fish, and the action of the magnetic drive forces of the rotating magnets, multiple toy fish are made to swim separately and in different directions simultaneously.
Claims17
A swimming toy system comprising:
- (a) an aquarium tank and water within the tank, the tank having a bottom wall and opposite side walls;
- (b) a toy swimming in the water within said tank, the water toy comprising a body having means to at least partially float the toy body, and a magnet within the body;
- (c) a first elongated housing and a second elongated housing, said housings being positioned at the bottom of the tank, on opposite side walls of said tank;
- (d) a first magnetic drive within said first elongated housing and a second magnetic drive within said elongated second housing, each magnetic drive comprising a rotatable spindle;
- (e) at least one magnetic member having north/south poles mounted on each spindle;
- and
- (f) means to rotate the spindle of the first magnetic drive in a clockwise direction and to rotate the spindle of the second magnetic drive in a counter-clockwise direction, to thereby cause the toy to rise and swim in the tank.
A swimming toy system comprising:
- (a) an aquarium tank containing water, said tank having a bottom wall and opposite side walls;
- (b) a plurality of water toys adapted to swim in water in said tank, each water toy comprising a toy body having means to at least partially float the toy body, and a magnet within said body;
- (c) a first elongated housing and a second elongated housing, each housings being adapted to be positioned proximate the bottom of said tank, on opposite side walls thereof;
- (d) a first magnetic drive within the first housing and a second magnetic drive within the second housing, each magnetic drive comprising a rotatable spindle;
- (e) means to rotatably mount each spindle;
- (f) at least one magnetic member having north/south poles mounted in each spindle;
- and
- (g) motor means to rotate the spindle of the first magnetic drive in a clockwise direction and to rotate the spindle of the second magnetic drive opposite thereto in a counter-clockwise direction to thereby cause the water toys to rise and swim in the tank.
