As is well known, ships are used for transporting people or baggage or fishing. Recently, with the rapid industrial development, the standard of living has been improved, and it is also used for leisure. As such, small vessels used for leisure can be largely divided into non-powered vessels and power vessels. The above-mentioned non-powered vessels, that is, vessels that obtain propulsion by paddles, have a lot of manpower and are slow, and in the case of beginners, change direction. There is this difficult problem. In addition, the power vessel, that is, the vessel using the engine is expensive, there is a problem in that the maintenance cost is excessively high fuel consumption.

On the other hand, even in the case of power ships, if the power unit breaks down, it may be necessary to paddle to obtain propulsion. In such a case, there is considerable difficulty when it is necessary to go back in the water or the river. For beginners, it is difficult to proceed to the target direction because rowing is not familiar.

On the other hand, in order to solve the above problems by using the power of the arm and leg paddles to obtain the power or the device that can selectively use the automatic power and manual power by installing the automatic power and manual power device in parallel For example, Korean Utility Model Registration No. 252492.

In other words, since the proposed devices are fixedly installed on the vessel as an auto / manual propulsion unit, they can be used only by those who are engaged in fishing or have economic margins and are only available to those with vessels such as trailers. There is a problem that the base expansion is not achieved.

Accordingly, the technical problem to be achieved by the present invention is to provide a compact marine foldable composite power unit to be configured to be mounted / detached from the vessel as needed to achieve the propulsion force to perform the movement of the vessel conveniently. There is.

It is desirable to be foldable. In addition, the hinge coupler 27 preferably applies a hinge such that the frame 21 is folded at an angle of 90 degrees only in the downward direction of the first moving plate 31.

Therefore, in another folding example of the manual power unit 2 and the power transmission unit 3 as described above, the frame 21 is positioned below the first moving plate 31 by the hinge coupler 27. In this case, the folding operation is performed in a state in which the height-adjustable saddle and the handle (not shown in the drawing) are removed from the frame 21 and the folding frame 21 is installed on the frame 21. Since the position of the planar quadrangular joint structure 26 is changed, the chain connection with the first power transmission sprocket wheel 321 of the support bar 32 is continuously maintained.

Therefore, when folding the manual power unit 2 and the power transmission unit 3 by another folding example of the present invention, the frame 21 of the manual power unit 2 is rotated with the hinge coupling unit 27 as the axis. It can be rotated to be deployed / contracted in the downward direction of the first moving plate 31, it is possible to perform the operation to mount and detach the vessel (especially small ship) more easily.

As described above, the foldable composite power unit for a small ship according to the present invention is configured to be mounted / detached from the ship as necessary to conveniently carry out the movement of the ship, it is possible to install / detachable from the ship combined power Since the device can be purchased separately, the economic burden of the consumer can be minimized, and the base of the demand can be expected to expand. In addition, the composite power unit of the present invention is configured in a deployment / contraction form to minimize the volume of each component as needed, and also by providing a sliding folding method or a rotating folding method to the folding method of each component, This convenient storage also has a convenient effect.
