This invention concerns a remote control unmanned boat which can be freely operated by remote control and a remote control device. The remote control unmanned boat comprises a propelling power source 11 for generating a propelling power, a steering device 13 for freely varying the direction of advance, a first transmit-receive antenna 24 for receiving the signal transmitted by ratio from a control device 20, a first controller 15 for controlling the propelling power source 11 and the steering device 13 based on the signal received from the first transmit-receive antenna 14, a memory device 17 for memorizing the initial position set in advance, and a GPS antenna 16 for receiving the electric wave transmitted from an artificial satellite. The first controller 15 calculates the present position based on the electric wave received by the GPS antenna 16 and, when the stated condition is satisfied, initiates automatic control of the propelling power source 11 and the steering device 13 so as to attain regression to the initial position based on the present position and the initial position. Thus, the remote control unmanned boat has no possibility of being missed.

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.

The present invention relates to a propeller, more specifically to a paddle wheel propeller, comprising a paddle wheel and a paddle plate, characterized in that: an air chamber with one end open and the other end closed is drilled on the axis of the paddle wheel , a number of paddle boards are installed on the circumference of the paddle wheel; the paddle boards are telescopic paddle boards, including a first paddle board and a second paddle board, the first paddle board is a cavity, and a rectangular sliding tube is embedded in the cavity , a sliding block is arranged inside the rectangular sliding cylinder, and a second paddle board is fixedly installed at the center of the outer surface of the slider block. The end of the first paddle board is provided with a sliding outlet, and the second paddle board protrudes from the sliding outlet or Indentation, several groups of telescopic springs are provided between the inner side of the slider and the inner side of the cavity; an air inlet channel is provided between the rectangular sliding cylinder in the cavity of the first paddle board and the pipe wall at the connection of the paddle wheel. The paddle wheel propeller is used in conjunction with the ship to provide thrust for it.

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.

A submersible device according to an embodiment of the invention includes a container configured to be selectively buoyant in a liquid. The container can have at least one of a variety of different buoyancy systems. For example, the container can include a reservoir where the volume can be adjusted. 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 electric motor toy transport trailer configured to transport an electric motor toy 21 includes a charger 17 includes a rechargeable main power source 17a and a charging connector 17c connected to the rechargeable main power source 17a via a cord 17b. The rechargeable main power source 17a is housed in the electric motor toy transport trailer body 12 in a manner such that the rechargeable main power source 17a is disposed at a position lower than the upper edge of tires 13. The charging connector 17c is stored in an openable and closable container box 14 provided on the electric motor toy transport trailer body 12.

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.
