As shown, the propulsion device of the non-powered boat of the present invention includes a pedal drive device, a steering wheel drive device, a steering device, and a forward and backward switching device.

The pedal drive device includes pedal gears 13 and 13 'provided opposite to the pedal shaft 12 including the pedals 11 and 11', one-way gears 15 and 15 'provided opposite to the rotary shaft 14, Guide gears 16 which are arranged in front of the one-way gears 15 and 15 'and both ends thereof are connected to the pedal gears 13 and 13', respectively, so that the one-way gears 15 and 15 'and the guide gear 16 are connected. Bevel gear at one end so as to be selectively engaged with the rolling chain 17 wound around the bevel gears, the bevel gears 18 and 18 'installed opposite to the rotating shaft 14, and the both bevel gears 18 and 18'. (19a) is installed, and the transmission shaft (19) and 19 'provided with the electric gear (19b) on the other end, and the transmission chain (20) is installed in the vertical direction to the electric gear (19c) of the transmission shaft (19'). It includes a propelling screw 21 connected to.

Handle driving device is a handle 31 is formed at the upper end of the hinge 32 vertically installed, the handle shaft 33, 33 ', the idle pulley 34, 34' installed opposite to the pedal shaft 12. , The one end gears 35, 35 'are disposed opposite to the rotation shaft 14, the pulleys 34, 34' and one direction gears 35, 35 'are wound on both ends of the handle shaft 33 ( 33 ') includes an electric wire 36a and an electric chain 36b connected to the ends.

The steering apparatus includes a steering key 41 vertically installed at the rear of the hull, a driving pulley 43 installed at the top of the steering key shaft 42, a steering wheel 44, a driving pulley 45 installed at the front of the hull, and the driving pulley. A wire 46 wound through the 43 and the circular pulley 45.

The forward and backward switching device includes a rotation shaft 14 having a key groove 14a, bevel gears 18 and 18 'installed on the rotation shaft, and a hinge 51 installed at the end of the rotation shaft to horizontally move the rotation shaft. Lever 52.

Reference numeral 1 is a hull, 2 is a chair, 17a is a connector for changing the direction of the transmission chain, 36c is a return spring.

The effect of this invention of the said structure is demonstrated.

According to the present invention, the propulsion screw 21 is rotated by stepping on the pedals 11 and 11 'in a zigzag manner, rotating the handle shafts 33 and 33' in the front and rear directions, or simultaneously operating the pedal and the handle shafts. The propulsion can be carried out by letting the propulsion be performed. First, the operation of the propulsion using the pedals 11 and 11 'will be described.

As shown in FIG. 3, the driver sits on the chair 2 and puts his feet on the pedals 11, 11 ′ and both hands grasp the handle 31 of both handle shafts 33, 33 ′. . At this time, if two people want to drive, two pedals and two handles are used separately.

In this state, when both pedals 11 and 11 'are alternately turned, both pedal gears 13 and 13' are rotated, and the rotational force is transmitted through the electric chain 17 to transfer both one-way gears 15. The rotating shaft 14 is rotated by rotating the 15 ', and the rotating force of the rotating shaft rotates the transmission shafts 19 and 19' through one bevel gear 18, thereby finally rotating the propulsion screw 21. .

At this time, the rotational force is increased through the transmission shafts 19, 19 'the gear ratio is different.

On the other hand, when propelling the hull with a steering wheel drive device by holding the handle 31 of the handle shaft 33 with both hands to rotate back and forth, the handle shaft 33 is pivoted about the hinge 32 is connected to the end The electric chain 36b and the electric wire 36a are pulled out.

Then, as described above by rotating the one-way gears 35 and 35 'caught on the transmission chain 36b, the rotational force is transmitted through the rotation shaft 14 and the one side bevel gear 18 to the transmission shafts 19 and 19. By rotating ') the propulsion screw 21 is finally rotated.

However, the pedals 11 and 11 'and the handle shafts 33 and 33' may be simultaneously operated and propelled, and in this case, an increased propulsion force may be obtained.

When changing the direction during propulsion, when the steering wheel 44, which is a steering device, is turned in the target direction, the electric wire 46 rotates the driving pulley 43 of the hull aft by the rotation of the prime pulley 45. This is possible by rotating the steering key 41.

In addition, in the case of reversing or stopping, when the switching lever 52, which is the forward and backward switching device, is removed, the switching lever is rotated about the hinge 51 to move the rotary shaft 14 connected to the end thereof. The forward bevel gear 18 is disengaged from the bevel gear 19a of the electric shaft 19, and the backward bevel gear 18 'is meshed with the bevel gear 19a, thereby changing the rotation direction. As the propulsion screw 21 is rotated in the reverse direction, it is possible to reverse or stop.

As described above, the propulsion device of the non-powered boat of the present invention is the propulsion device of the non-powered boat, wherein the pedal and the handle may be selectively or selectively by integrally configuring a pedal drive device, a steering wheel drive device, a steering device, and a forward and backward switching device. It can be driven and driven simultaneously, and it is easy to propel to one or two people, and it can get more propulsion with less power. It is very easy to steer and brake, so everyone can enjoy it easily. It has an effect.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
