When the center of the steering handle 63 'is fixed to the connection bracket 77 and the steering handle 63' is operated in both left and right directions, the connection tube 79 and the fixing bolt 27 are turned The hinge pin 75 inserted into the elongated hole 78 of the connection bracket 77 is moved under the guidance of the elongated hole 78 while one side of the connection bracket 77 is rotated in both directions.

When the hinge pin 75 is guided by the slot 78, the first rotation bracket 73 is rotated in the left and right direction within a certain range of angles, and the rudder 62 connected to the first rotation bracket 73 'And the second rotation bracket 76 are also rotated together.

The driving unit 5 includes a housing 50 formed in front of the frame unit 2 and having a driven gear G1 and a driven gear G2 mounted therein; A pedal 52 connected to the main gear G1 of the housing 50 to be pushed by the user; And a shaft 53 connected to the driven gear G2 of the housing 50 and transmitting rotational force to the propeller 3.

As shown in FIG. 3, the main gear G1 and the driven gear G2 are made of bevel gears, and can change the direction of the rotational force of the pedal 52. As shown in FIG.

And the driven gear G2 is disposed such that its axis G22 is inclined downward toward the propeller 3 disposed below.

It is preferred that the pedal 52 is applied in a foldable manner so as to minimize volume when it is separated and stored. Since the folding pedal is a known technical idea, a detailed description thereof will be omitted.

One end of the shaft 53 is connected to the axis G22 of the driven gear G2 disposed at a downward inclination by a universal joint J and the other end is connected to the shaft 32 of the propeller 3 horizontally mounted Universal joint (J).

The shaft 53 is made of steel or a flexible material such as wire to cause the propeller to oscillate.

FIG. 10 is a view showing another embodiment of the shaft according to the present invention. The present invention is characterized in that the leisure boat is assembled into a plurality of parts, so that the shaft can also be separated.

The first shaft 510 and the second shaft 520 are separated from each other by the slide member 530 and the first shaft 510 and the second shaft 520 are separated from each other by the slide member 530. [ .

That is, the first shaft 510 has a key 511 at one end and a key groove G23 at the end of the shaft G22 of the driven gear G2 so that the first shaft 510 and the driven gear G2 And the shaft G22 of the first shaft 510 is coupled with the key groove 511 by the key groove G23 and is rotatable together. The other end of the first shaft 510 is surrounded by the outer periphery of the first shaft 510 And a slide member 530 which can be moved back and forth along the outer circumference of the first shaft 510 is installed.

The other end of the first shaft 510 is provided with a stopper having a diameter larger than the diameter of the first shaft 510 so that the slide member 530 can be prevented from being separated from the first shaft 510. [ And a locking member 531 bent inward is formed on one side of the slide member 530 fitted to the first shaft 510 so that the slide member 530 moves from the first shaft 510 forward and backward The engagement portion 531 is prevented from being completely released from being caught by the engagement protrusion 512 of the first shaft 510. [

A key groove 513 is formed at the other end of the first shaft 510 and a key 521 is formed at one end of the second shaft 520 so as to be inserted into the key groove 513 and rotated together One end of the flexible shaft 80 is fixed to the other end of the second shaft 520 by means of fastening means and a key 81 is formed on the opposite side of the flexible shaft 80 so that the axis of the propeller 3 The propeller 3 can be rotated in accordance with the rotation of the flexible shaft 80. [

Here, the flexible shaft 80 is a shaft which is made flexible so as to change the axial direction, and is a shaft in which a thin wire is wound in a coil shape to have multiple folding and bending properties, Although the second shaft 520 and the propeller 3 may be connected to each other by using the flexible shaft 80 as described above, it is not necessary to limit the second shaft 520 and the propeller 3 to the flexible shaft 80, and the universal joint J may be used .

In the figure, the reference numeral 28 denotes a support ring, in which a first shaft 510 connected to a shaft G22 of the driven gear G2 is fitted to a support ring 28 formed in the front frame 21, The first shaft 510 and the second shaft 520 are prevented from slacking while the first shaft 510 is supported by the ring 28 so that the center of rotation of the first shaft 510 and the second shaft 520 So that it can be kept constant.

In the figure, a reference numeral 540 denotes a movement preventing ring. The first shaft 510 and the second shaft 520 are connected to each other by the slide member 530 as means for controlling the movement of the slide member 530 The first shaft 510 and the second shaft 520 are prevented from being separated from each other by the slide member 530. At this time, the movement preventing ring 540 is inserted into the engagement portion 531 of the slide member 530 The slide member 530 is prevented from being moved by the movement preventing ring 540. When the first shaft 510 and the second shaft 520 are to be separated from each other, 540 are moved away from the slide member 530 so that the first shaft 510 and the second shaft 520 can be easily separated while the slide member 530 is freely moved.

At this time, it is preferable that the anti-movement ring 540 is made of a material having an elastic force such as rubber.

Hereinafter, the operation of the present invention will be described.

When the person steers the steering wheel 63 with both hands while riding on the chair and rotates the pedal 52 by pushing it, the driving force of the driving unit 5, the rotation of the shaft 53 and the rotation of the propeller 3 Is generated and advanced.

Or if the pedal 52 is depressed in the opposite direction, the propeller 3 is rotated in the opposite direction, so that the propeller 3 can be reversed.

And can be safely moved to a desired place by changing the direction by operating the steering wheel 63. [

Although the present invention has been described in connection with the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
