The operating member 240 is disposed on the second side of the housing unit 230 so that the forward direction of the buoyant bodies 110 and 120 can be determined by rotating the propeller 220 relative to the pair of pedals 210. [ And is connected to the case 233 in a power-driven manner.

Here, the center frame 4, to which the pedals 210 are rotatably supported, is installed on the buoyant bodies 110 and 120, and the housing unit 230 is provided with the housing unit 230 on the center frame 4 It is preferable to provide a mounting bar 235 for detachably connecting.

According to an embodiment of the present invention, the housing unit 230 is detachably connected to the center frame 4 via the stop bar 235, so that the pedal 210 and the propeller 220 The connected housing unit 230 can be attached and detached, and the housing unit 230 can be detached and managed separately when the unit is broken.

The second case 233 is provided with a connecting bar 237 which is connected to the operating member 240 in a power connection manner and a direction driving lever 241 is connected to the connecting bar 237. As described above, according to the embodiment of the present invention, since the key for steering the direction of the canoe is not separately provided, the construction of the kayak is simplified.

As such, after the housing unit 230 is coupled to the center frame 4, the direction driving lever 241, in which the user directly moves, is coupled to the connecting bar provided in the second case 233, as in the embodiment of the present invention, The power transmission unit can be easily installed on the kayak by simply connecting the power transmission unit 237 to the power transmission unit 237. [

Next, the connection unit used to connect the buoyant body among the elements in the pedal kayak will be described as follows.

4 and 5, the connection unit employed in an embodiment of the present invention includes a first buoyant body 110, a second buoyant body 120, a first profile 130, a second Profile 140 and a plurality of connection profiles 150.

Here, the first buoyant body 110 and the second buoyant body 120 are divided into a first buoyant body 110 and a second buoyant body 120 according to the same structure or location, And the second profile 140 have the same function as those of the second profile 140 according to their installation positions.

A plurality of first buoyant bodies 110 are arranged on both sides along the one-directional axial direction, through holes 111 are formed along the axial line, and the first profiles 130 are inserted into the through holes 111.

The plurality of second buoyant bodies 120 are arranged along an axis parallel to the axial line and are each formed with a through hole 121 and inserted into the through hole 121 of the second profile 140.

The plurality of first profiles 130 are respectively inserted into the through holes 111 of the first buoyant bodies 110 and the opposite ends of the first profiles 130 are coupled to each other to support the first buoyant bodies 110.

The first profiles 130 fastened to the end of the first profiles 130 are connected to the first profiles 130 on one side and the first profiles 130 on the other side so that the first buoyant bodies 110 are not released to the outside. 135 are preferably provided.

The plurality of second profiles 140 are respectively inserted into the through holes 111 of the second buoyant bodies 120 and the ends facing each other are coupled to support the second buoyant bodies 120 . Meanwhile, the second profiles 140 fastened to the end of the second profile 140 may have the same shape as the first profile 140 and the second profile 140, 145 are preferably provided.

On the other hand, the connection profiles 150 connect the first profiles 130 and the second profiles 140.

Since the skeleton constituting the kayak can be assembled through the first profile 130, the second profile 140, and the connection profile 150, various kinds of pedal kayaks according to the number of passengers can be easily It has the advantage of being cooked.

The first profile 130 and the second profile 140 are each provided with a female screw 133 on one of the adjacent elements and a male screw 131 on the other, Is preferably provided.

As described above, according to the first profile 130 and the second profile 140, a separate structure for joining the first profile 130 and the second profile 140 constituting the skeleton of the pedal kayak is not required Therefore, there is an advantage that the kayak can be assembled easily.

In addition, the connection profile 150 preferably has a connection hole in which a portion of the first profile 130 and the second profile 140, on which the male thread portion is formed, is rotatably fitted. When the connection hole 150 is formed in the connection profile 150, the first and second profiles 130 and 140 may be formed by fitting the male and female threads of the first and second profiles 130 and 140 into the connection hole. And the connection profile 150 can be bound to each other.

Hereinafter, an assembling process of the connecting unit for connecting the buoyant body among the elements constituting the pedal kayak will be described below.

First, the first profile 130 is inserted into each first buoyant body 110, and the adjacent first profiles 130 are screwed together. Then, the second profile 140 is inserted into the second buoyant body 120 in the same manner, and then the second profiles 140 are screwed together.

The first profile 130 inserted in the first buoyant body 110 and the second profile 140 inserted in the second buoyant body 120 are then coupled with the connection profile 150. At this time, the male threads 131 and 141 of the first profile 130 and the second profile 140 are inserted into the respective connection holes 151 of the connection profile 150, respectively.

The first profile 130 inserted into the other first buoyant body 110 is screwed into the first profile 130 inserted in the connection hole 151 of the connection profile 150, The pedal kayak is completed by screwing the second profile 140 inserted into the connecting hole 150 to the second profile 140 inserted into the connecting hole 151 of the connecting profile 150.
