As shown in the plan view of FIG. 3, the bolt 1 includes a wheel protector 2 having an upper surface opened such that an engine portion and a rear wheel 16b of a motor cycle 15, which will be described later, are fitted into the center. ) Protrudes downward, and cylindrical air tubes 3 are formed long side by side on both sides of the upper portion of the wheel protector 2.

On the other hand, the wheel protector (2) is the front and rear portion (2a) (2b) of the rigid, the thickness of the relatively thick steel plate is integrally joined to the air tube (3) on both sides, the rigid plate Rotating shaft (5) is installed in the rear portion (2b) is a screw shaft (4) is installed to receive the driving force generated from the rear wheel (16b) of the motor cycle (15) to generate a propulsion force on the bolt (1) itself On the rear side of the rear portion 2b, a cylindrical screw cover 6 surrounding the screw right 4 and a steering key 7 for adjusting the direction of the bolt 1 are provided.

A connecting rod 8 having a predetermined length (approximately 30 cm or so) is provided across the top of the steering key 7, and a wire-shaped steering cable 9a (at both ends of the connecting rod 8) ( The rear ends of 9b) are symmetrically bound side by side, and the leading ends of the steering cables 9a and 9b are connected to the handle 17 side of the motor cycle 15.

Accordingly, the steering direction of the boat 1 is adjusted by rotating the steering key 7 at a predetermined angle as the steering cables 9a and 9b are pulled while operating the handle 17 to the left and right.

Reference numeral 11 is a fixing rod that is fixed to the both side tube (3), the tube 3 is bound to the motor cycle (15).

The fixed rod 11 is installed on the rear upper portion of the boat 1 formed of both side tubes 3 and the wheel protector 2, and is fixedly coupled to the rear bearing 18 of the motor cycle 15, Bars 12 having rollers 12a and a furnace 12b are rotatably fitted at both end portions of (11).

Accordingly, the entire boat 1 including the motor cycle 15 is lifted in the state in which the roller 12a comes into contact with the ground by rotating the bar 12, and is easy to move from the ground to the water surface. Stir) to move the boat (1).

On the other hand, the structure of the motor cycle (15) mounted on the boat (1) is as follows.

The front wheels 16a and the rear wheels 16b of the motor cycle 15 are each provided with ring-shaped gears 19a and 19b (see Fig. 2). The power transmission cable 20 is connected between the ring gears 19a and 19b so as to send the driving force generated from the rear wheels 16b to the front wheel 16b side.

Of course, bevel gears 20a are installed at both ends of the power transmission cable 20 so as to be connected to ring-shaped gears 19a and 19b.

On the other hand, the ring-shaped gears 19a and 19b are equally divided as shown in FIG. 4 so as to facilitate the operation at the time of attachment and detachment to the model motor cycle 15.

That is, the three-part portions are connected to each other without shifting the teeth so as to be connected to each other in a scanning (scanning) shape, and the bolts 21 are spaced at predetermined intervals from the rear of the ring-shaped gears 19a and 19b divided by the blades. ) Is installed, and fixing plates 22 having the same size as the gears are separately formed on the rear side of the divided gears 19a and 19b.

Therefore, when the gears 19a and 19b thus formed are installed on the front and rear wheels 16a and 16b, the wheels 23 provided on the front and rear wheels 16a and 16b of the motor cycle 15 are provided. It is fitted in the blade to be fixed to form a circular (ring-shaped) as a whole, it is easy to attach and detach the gear (19a) 19b.

On the other hand, the bevel gear 24 of the front end of the rotary shaft 5, in which the screw right 4 is installed, is connected to the rear wheel 16b side gear 19b to receive the driving force generated from the rear wheel 16b. As a result, the screw 4 is rotated so that the boat 1 is propelled.

In addition, the rear wheel cover 25, which is easy to bend at an angle of 90 degrees, is installed at a lower portion of the rear wheel 19b at a predetermined distance from the rear wheel by the support 25a, so that the rear wheel 19b and the wheel protector 2 are provided. It is free to rotate without contact.

In the figure, reference numeral 26 denotes a clamp for supporting the cable so that the bevel gears 20a provided at both ends of the power transmission cable 20 are securely connected to the ring gears 19a and 19b.

Looking at the effect of the invention designed as described above are as follows.

When the motor is normally used as a motor cycle, the ring gears 19a and 19b, the power transmission cable 20, and the rear wheel cover 25 installed on the boat 1 and the front and rear wheels 16a and 16b are removed. For example, when using as a waterborne boat, the boat 1 first removes the air filled in the air tube 3 and spreads it on the ground, and the motor cycle 15 is moved as described above. After the ring-shaped gears 19a and 19b are installed on the rear wheels 16a and 16b and the power transmission cable 20 is installed between the gears 19a and 19b, the boat 1 laid on the ground described above is provided. After moving to a predetermined position of the rear wheel cover (25) to raise the motor cycle (15) and then inject air into the air tube (3) and at the same time the fixed rod (11) carrier of the rear side of the motor cycle ( When it is fixed to the 18) side, the boat 1 is in a state of engaging the motor cycle 15.

In this state, the bar 12 is installed on the left and right sides of the fixed rod 11 so that the roller 12a is brought into contact with the ground, and then the motor 15 is driven and driven to drive the rear wheel 16b. Since the driving force is transmitted to the front wheel 16a and the front wheel 16a rotates, the rear wheel 16b is naturally held on the ground and moved by the rotation of the roller 12a.

When placed in the water phase in such a state, the buoy 1 on which the motor cycle 15 is mounted is buoyed by the buoyancy force of the two cylindrical air tubes 3 and the wheel protector 2, When the rotational force is accelerated, the rotating shaft 5 connected to the rear wheel gear 19b transmits the rotational force to the screw right 4 so that the boat 1 itself is propelled.

At this time, in order to adjust the traveling direction, as the handle 17 is rotated in a predetermined direction, the steering cables 9a and 9b connected to the handle 17 rotate the steering key 7 at a predetermined angle. It is adjusted in the desired direction.

As described above, the present invention provides ring-shaped gears 19a and 19b on the front and rear wheels 16a and 16b of the conventional motor cycle 15 so that the driving force is transmitted to the front wheel and the screw wheel 4. Simultaneous movement of the ground, the propulsion force is generated when the floating in the water to improve the usability, and its structure is also simple compared to the conventional structure is good in manufacturability.
