Description

[Detailed explanation of the idea] [Industrial application field] This invention concerns a toy submarine.

[Conventional technology]

There have been various diving means for toy submersible boats, but the first one, as typified by Japanese Patent Laid-Open No. 157479/1983, uses a screw for running on water as well as a screw for diving. It is installed separately, and the diving is carried out by wireless operation of the drive motor of the diving screw, and the buoyancy of the hull is used for surfacing. Preparation, diving, and surfacing are performed by selecting the inclination angle of the elevator installed on the side of the hull.The third type is equipped with a screw for constant running as described in Japanese Patent Publication No. 1989-19096, and the screw is driven. The motor can be switched between forward and reverse, and when the submersible rudder is turned in the direction of diving and the screw drive motor is rotated, the device dives.When the water pressure increases due to diving, the built-in hydraulic expansion bag expands and switches the switch. , one in which the screw is rotated in the opposite direction to levitate is known.

However, all of the above-mentioned devices have the disadvantage that they are complicated in structure and expensive.

[Purpose of invention]

This invention is intended to solve the above-mentioned problems, and aims to provide a toy submersible with a simple structure and low cost.

[Structure of the idea]

This idea turns on the pump drive motor by operating a light receiving element that receives the light beam from the light emitter.
The watercraft is constructed so that it can be submerged by the jet force of the pump, and when the hull dives to a depth at which the light beam of the emitter no longer reaches the light receiving element, the hull floats to the surface by its own buoyancy. has been achieved.

[Explanation of Examples]

Next, this invention will be explained based on embodiments shown in the accompanying drawings.

Reference numeral 1 indicates a boat hull, and 2 indicates a pump chamber with a liquid-tight structure provided within the boat hull 1. A drive motor 3 constituting the pump is mounted in the pump chamber 2. The hull 1 has an L-shaped flow pipe 4 extending vertically through its center.
The upper end of the flow pipe 4 opens at the center of the upper surface of the hull 1 to form a water fountain 5, and the lower end opens at the lower surface of the hull 1 to form a water intake port 6. A fan 7 connected to the rotating shaft 31 of the motor 3 is disposed near the water inlet 6 in the flow pipe 4, and the water inlet 6 is opened by a pumping action caused by the rotation of this fan.
The water absorbed from the water is discharged from the water fountain 5 through the flow pipe 4, and the diving force of the hull 1 is applied as a reaction to this water fountain force.

The bottom surface 8 of the hull 1 is provided with an opening 81, the top surface 9 is provided with an opening 91, and the deck 1' is provided with a concentric gap to allow water to circulate inside the hull 1. I'm starting to do that.

The hull 1 has an upper surface 9 when no diving force is applied.
The hull 1 is made of synthetic resin so that it has a buoyancy that is almost equal to the water surface (that is, buoyancy that fills the water fountain). A plurality of floats 10 are provided at appropriate positions on the upper inner wall of the hull 1 in order to adjust the balance. In addition, since the buoyancy may vary depending on the type of water in which the hull 1 is submerged, such as fresh water, seawater, hot spring water, etc., in order to adjust the buoyancy, a weight 30 can be detachably attached to an appropriate location on the hull 1. I have to. Although the weight 30 is shown in the drawing as a coin-shaped piece of iron and plated, the weight 30 is not limited to this. The means for attaching the weight is not particularly limited, but the weight may be installed in a slotted manner by providing a groove frame 31 as shown in the figure, but it may also be installed in a resting manner on the upper surface of the deck 1' of the hull 1. Needless to say.

Reference numeral 11 denotes a battery chamber with a liquid-tight structure provided in the hull 1 similarly to the pump chamber 2, and a battery 12 is installed in the battery chamber. The battery 12 is attached and detached by opening and closing a lid 121 equipped with a terminal.
1 has a rubber cover 12 to improve waterproofness.
2 is crowned.

13 is a lead wire for supplying power from the battery chamber 11 to the motor 3 of the pump chamber 2 or a circuit to be described later.

Reference numeral 14 denotes a light-receiving element that also serves as a lid disposed on the upper part of the pump chamber 2, and the light-receiving element 14 is illuminated from above the water surface by a light emitting device prepared in advance through a light projector 15 provided on the upper surface of the hull 1. It receives a light beam projected from 20 (an ordinary flashlight or the like may be used) and outputs an operation signal for operating the motor 3. FIG. 3 is a block diagram showing an example of a circuit for processing this operation signal. 4
0 is a photoelectric conversion circuit, and 41 is a drive circuit that receives the output of the photoelectric conversion circuit 40 and drives the motor 3. These circuits are housed in a space above the pump chamber 2 in a mounted state.

Note that since each circuit has a well-known configuration, its details will be omitted.

16 is a spectacle-like device provided at the front of the hull 1;
7 is an arm-shaped device. These are intended to add anthropomorphic elements to the hull 1 and to arouse the interest of children and the like.

Next, the operation of the above embodiment will be explained.

The illustrated toy submarine is first placed on the water surface as shown in FIG. 4A. Since openings are provided in the lower surface 8 and upper surface 9 of the hull 1, water flows into the interior of the hull through the openings on the lower surface, while air escapes from the openings on the upper surface, causing the submersible to lose its own weight. The boat dives to a position where the buoyancy and buoyancy are balanced, and stops when the top surface of the hull 1 reaches a position where it is almost equal to the water surface. Add weight 3 as necessary to adjust buoyancy depending on the type of water.
Attach 0.

Next, the user holds the light emitting device 20 in his hand and emits light toward the light projecting section 15 of the boat body 1 from above the water surface. The light beam emitted from the light emitter 20 is received by the light receiving element 14 via the light projecting section 15, and outputs an operation signal.
is input to the photoelectric conversion circuit 41, and as a result, the motor 3
rotates, and the fan 7 attached to the motor 3 rotates. Due to the pump action caused by the rotation of the fan 7, water is sucked from the water intake port 6, and
The absorbed water is discharged upward from the water fountain 5.
At the same time, due to the reaction of the fountain force, the submersible is
It receives a downward diving force and starts diving.
At this time, since the fountain 5 is located at the center of the top surface,
This allows the boat to dive in a stable state without tilting. The light receiving element 14 outputs an operation signal as long as it receives the light beam from the light emitter 20, so the motor 3 continues to operate while the light beam from the light emitter 20 reaches the light receiving element 14, and the submersible goes deep. and continued diving.

When the hull 1 dives to a depth where the light beam of the light emitter 20 no longer reaches the light receiving element 14, or when the light emitter 20 is turned off or removed to stop emitting light, the light receiving element 14 Since the operation signal outputted from the water fountain 14 disappears, the motor 3 stops, and the jetting force from the water fountain 5 disappears. As a result, the hull 1 begins to float due to the buoyant action of the synthetic resin that is its constituent material and the float 10. Thereafter, using the same principle, it becomes possible to re-dive during ascent or change to ascent during diving.

[Effect of idea]

As explained above, this invention has a hull that has a moderate buoyancy and is designed to submerge by the water jet force of a pump, and receives a light beam from a light emitter and outputs an operating signal for the drive motor of the pump. A light-receiving element is provided to control the ON/OFF of the pump drive motor depending on the presence or absence of light from the light emitter, and when the drive motor is turned on, the boat is submerged by the jet force of the pump. When the boat is turned off, it floats to the surface of the water due to the buoyancy of the boat itself, so the structure is extremely simple and inexpensive to manufacture compared to conventional ones, making it ideal for children to easily enjoy in bathtubs, etc. We can provide a variety of toy submarines.
