A water submergence toy is not performed using a screw. It is done by only changing the buoyancy by means of changing the volume. Because of this, the control and surfacing responsiveness becomes very poor. The water submergence toy according to the present invention compresses the air inside a piston when the piston is pushed towards the inside of a cylinder to reduce the volume. This makes the buoyancy smaller. Conversely, when the piston is moved in a direction away from the cylinder, the volume of the air inside the piston becomes larger and the buoyancy increases. In addition, because this type of buoyancy adjustment can be performed manually as well, those who play with a water submergence toy can adjust the buoyancy whenever it is necessary. Because of this, the buoyancy of the water submergence toy can always be maintained in a state adjusted for optimum buoyancy.

A water toy includes a pair of floatable hulls arranged in spaced apart orientation in a generally longitudinal direction relative to the toy. A water wheel support is coupled to the hulls and has inner sides positioned on either side of the water wheel. A water wheel axel spans laterally between the inner sides and perpendicular to the longitudinal direction of which the hulls are oriented. A water wheel is mounted on the axel and rotates forwardly about a rotating axis such that lower paddles of the water wheel dip into the body of water forwardly of the axel and push rearwardly as the water wheel rotates to thereby propel the water toy forwardly through the water. A water container is mounted above the water wheel and provides fluid through an aperture to the water wheel to thereby drive the paddles of the water wheel about the rotating axis.

A toy ship and associated toy navy wherein the toy ship has multiple chambers within the hull, each chamber having a plug below the water line to allow entry of water to sink the ship. The child determines as a matter of play that the ship has been struck by a projectile or torpedo and appropriately should have one or more plugs pulled. The child then pulls the plug(s) allowing entry of water to sink the ship. As the ship is struck further, more plugs may be pulled by the child to hasten sinking of the ship. The plugs may be fabricated to remain with the ship when pulled so as not to get lost or become a swallowing hazard for the child. The ship may be provided in association with a toy submarine, a toy airplane and/or a second toy ship, which may be of different design.

In another example, the container can include a reservoir in communication with a pump configured to control the intaking and expelling of a liquid. In another embodiment, the container also defines a first partitioned section and a second partitioned section. The first partitioned section is substantially liquid resistant and the second partitioned section defines a hole in communication with an exterior of the container. An actuator is configured to receive an input from a user and is configured to modify an interior volume of the second partitioned section based on the input.

An integral pump assembly may be used to power a toy vehicle. The pump pressurizes fluid stored within the pressure vessel. The pressurized fluid within the pressure vessel drives the engine that powers the toy vehicle until the stored pressurized fluid has been depleted. The pump may then repressurize the pressure vessel to again drive the pneumatic engine. The pump is substantially disposed within the body of the toy vehicle.

A diving toy that is comprised of a housing with a motor, battery and magnetic reed switch positioned inside the housing. A propeller is attached to an axle of the motor protruding through the rear end of the housing. A ballast is arranged inside the housing to provide positive buoyancy and a front end down attitude. A plurality of fins protrude from the housing surrounding the propeller for improving directional stability. A lever having one end rotatably mounted to the outside of the housing and another end provided with a magnet. When the toy is dropped or thrown front end first into a body of water, or when pushed in a downward motion from a submerged state, hydrodynamic forces rotate and then hold the lever and accordingly the magnet in a rearward position so long as there is downward motion, aligning the magnet adjacent to the reed switch, thereby actuating the reed switch to close a circuit between the battery and motor activating the motor, and forces generated by the spin of the propeller overcome the toys positive buoyancy propelling the toy in a continuous dive until it collides with a bottom of the body of water or another object stopping the dive, whereby gravity rotates the lever and magnet forward away from the reed switch to shut off the motor, the positive buoyant toy then floats to a surface of the body of water where it can be launched into another dive.
