Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a single-person towing machine used for swimming, water rescue, and the like.

(Prior art) Conventionally, a one-person water transportation machine equipped with its own power,
Motorboats and water scooters, both of which had steering devices, were mainly used for sports purposes.

(Problems to be Solved by the Invention) The above-mentioned vehicle requires sufficient buoyancy to carry a person and float on the water, and power to carry a person and run on the water, and also has a steering device. The problem is that it has a large volume and is heavy, making it difficult to easily carry it, and it is also expensive, making it difficult to popularize it for general leisure purposes.

Therefore, the present invention aims to break away from the idea of a vehicle and create a vehicle that is small, lightweight, and inexpensive. The purpose of this invention is to solve the above-mentioned conventional difficulties and provide a towing machine mainly for leisure use that is simple and inexpensive enough to be carried with one hand and has high popularity. That is.

(Means for Solving the Problems) To achieve the above object, the present invention installs an engine that drives a propulsion device via a centrifugal clutch in a hollow boat-shaped casing with air intakes provided at appropriate locations. This towing machine has a handle with an accelerator attached to the rear of the casing.

In addition, an engine that drives a propulsion device via a centrifugal clutch is installed in a hollow boat-shaped casing that has an air intake port at a suitable location, and the exhaust gas is used to drain the water that accumulates inside the casing into the exhaust gas passage of the engine. A drain pipe connected to the bottom of the casing is opened and provided to extract and drain water.
Furthermore, the towing machine is equipped with a handle with an accelerator device at the rear of the casing.

In addition, a jet pump is used as the propulsion device for the towing machine,
At least a portion of the jet pump is exposed below the casing, so that the jet pump is located substantially below the water surface when in use.

(Function) In the towing machine of the present invention having the above configuration, when the engine is started and floated on the water, the accelerator is not accelerated, so the centrifugal clutch is in the OFF state due to idling operation, and the propulsion device is not driven. The towing machine is stationary, and in this state, if you hold the handle and accelerate the accelerator while swimming, the engine rotation will increase, the centrifugal clutch will turn ON, the propulsion device will move, and the towing machine will move. It is what pulls people into swimming.

In this type of towing, the swimmer adjusts the accelerator to accelerate or decelerate the speed, and the swimmer himself steers by opening or bending his legs to the right or left, or by extending or retracting his right or left hand holding the handle. This is what makes it interesting, and allows you to enjoy swimming while enjoying the sense of speed and exhilaration.

If you accidentally let go of the steering wheel while swimming, the accelerator will automatically return, the engine will decelerate, and the centrifugal clutch will turn off.
It goes FF and stops naturally.

In addition to being used for water swimming as a sport and leisure activity as described above, this towing machine is also suitable for use in water rescue operations, such as at beaches.

(Example> Hereinafter, the present invention will be explained in detail based on the drawings.

(1) is the casing body, (2) is the casing lid body,
Both are made of heat-resistant reinforced plastic or corrosion-resistant metal, and are joined by covering the upper part of the casing body (1) with a nurse song lid (2), and an air intake port (3) is provided at the rear end of the joint. It is open and has a hollow interior.

(4) is an engine which is electrically connected inside the casing body (1) and drives a jet pump (6) which is a propulsion device via a centrifugal clutch (5).

This jet pump (6) is partially exposed at the bottom of the casing body (1) through a hole (7) bored in the bottom of the casing body (1), and is configured to be located almost under the water surface when in use. In addition, an inlet (8) is opened in front of this exposed part, and an injection nozzle (9) is provided diagonally downward at the rear, so that suction can be taken from the inlet (8). Water is propelled by a jet stream that sprays water diagonally backward and downward into the water from a spray nozzle (9).

4 is a handle, which protrudes from both sides of the rear end of the casing body (1) and is bent upward, and the - side handle C1O has an accelerator lever for accelerating the engine (4).
(6) is a provision.

(2) is a muffler, the mouth is an exhaust gas passage, q is a bulge provided in the middle of this exhaust gas passage, Q5 is a drain pipe, and this drain pipe αQ has one end at the outlet of the bulge Cl-1). The other end is open at the bottom of the casing body (1), enters through the air intake port (3), and the other end is opened at the bottom of the casing body (1).
) The water that has accumulated at the bottom of the exhaust gas is drawn out by the exhaust gas and is discharged together with the exhaust gas.

This drainage device does not require a special drainage pump, and can be manufactured easily and at low cost.

Also, since the ampullae α→ has a noise silencing function, it can be used in conjunction with the muffler □□□ to achieve a silencing effect, and in some cases it can also be used as the 77r@.O ae is the engine starter, αη is a carburetor, (g)
indicates the fuel tank, QCJ indicates the fuel pipe, the handle indicates the spark plug, 3υ indicates the engine stop switch, and 4 indicates the portable handle.

In the above embodiments, a jet stream is used as the propulsion means, but a screw may be used for propulsion. Since it only pulls a human body floating on the water surface, it requires only a small amount of power, and it can be made lightweight and compact, making it simple and easy to carry. The towing machine can be enjoyed to the fullest, is suitable for practical use such as water rescue, and has a simple structure and low cost, making it a highly popular towing machine.
