Abstract

PURPOSE:To provide a repairable and inexpensive pedal type propulsion unit capable of freely adjusting the speed of a boat by treading and being simply and easily fitted or removed. CONSTITUTION:The driving force by a pedal 6 is transmitted to a propeller unit 7 through a timing belt, and a boat is propelled by the propelling force generated by the propeller unit 7. The traveling direction of the boat is adjusted by a steering rod 10. This pedal type propulsion unit 1 is completely set when a lower casing 3 is merely coupled with a cylinder fitted to the bottom of the boat.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedal type propulsion device for propelling a boat by stepping on a pedal, a boat for installing the pedal type propulsion device, and a pedal type propulsion device provided with the pedal type propulsion device. It concerns propulsion boats.

[0002]

2. Description of the Related Art In recent years, fishing in lakes has become popular. In this fishing, a boat having an outboard motor with an internal combustion engine and a boat having an electric motor at the bow in addition to the outboard motor with an internal combustion engine are used. When using these boats for fishing, a procedure is used in which after approaching the point by an outboard motor with an internal combustion engine, the point is attacked by an oar or an electric motor.

[0003]

However, the sound of the outboard motor with an internal combustion engine is so loud that the operation must be stopped at a considerable distance from the point in order not to alert the fish. Further, when the oar is used to attack the points, the reel and the like cannot be handled while the oar is operated, and the fishing efficiency is very poor. In that respect, the one that uses an electric motor has both hands free and the fishing efficiency is good to some extent, but the boat speed is 5 km /
h is slow and it takes time to attack points. Furthermore, a boat equipped with an outboard motor with an internal combustion engine or a power generator such as an electric motor can be operated only by a person who has a marine license, and beginners cannot easily enjoy fishing. In addition, such a power machine also has a problem of running out of energy. Furthermore, since these motive power machines are heavy, maintenance is labor intensive, and it takes time and effort to remove aquatic plants on the spot when the aquatic plants are wound in shallow water, for example. Moreover, such power machines are by no means cheap.

The present invention has been made in view of the above problems, and even a person without a license can handle it easily, and by adjusting the leg strength, the boat can be freely advanced without making a noise that warns the fish. It is an object of the present invention to provide an inexpensive pedal type propulsion device that can be easily repaired when a problem occurs, a boat to which this device can be attached, and a pedal type propulsion boat to which the device is attached. is there.

[0005]

The above objects of the present invention are as follows:
(A) An upper pedal type driving force generating mechanism and (b) a pedal type driving force generating mechanism connected to a lower side of the pedal type driving force generating mechanism so that the driving force generated by the pedal type driving force generating mechanism is transmitted. A pedal-type propulsion device including a propeller unit for converting into a propulsion force, wherein a hole is formed in the ship bottom and a cylindrical body having a shape corresponding to the hole is provided so as to project into the ship. Connected to the lower side of the pedal type driving force generation mechanism so that the driving force generated by the pedal type driving force generation mechanism and the upper pedal type driving force generation mechanism are transmitted. A pedal type propulsion device including a propeller unit for converting into a force is provided in the tubular body having a shape corresponding to the hole provided so as to project from the hole formed in the bottom of the ship into the ship. Raw mechanism the propeller unit located on board is achieved by the pedal propulsion boat, characterized in that it is installed so as to protrude downward from the vessel bottom through the tubular body.

[0006]

When the pedal type propulsion device of the present invention is used, the boat is moved by stepping on the pedal with a person's foot. Therefore, even a person who does not have a license to operate the motor of the boat can move the boat with his foot while manually operating the fishing rod. You can control and enjoy fishing. The speed of the boat can be adjusted freely by adjusting the pedaling force. In addition, the propulsive force of this boat is generated by the foot of a person and no power generator is used, so that no mechanical noise that a fish warns is generated. In addition, there is no problem of running out of energy like a power generator, so there is no need to equip the boat with oars. Further, the structure is simple and the weight is light, so that it can be easily attached to and detached from the boat and can be easily repaired in the case of a failure, and the simple structure is inexpensive to manufacture. If the pedal type propulsion device of the present invention is provided with the steering mechanism that changes the propulsion force generation direction of the propeller unit, the boat can be advanced in any direction, and a precise point can be easily grasped.
A timing belt is preferable as a means for transmitting the driving force from the pedal type driving force generating mechanism of the device of the present invention to the propeller unit because it is inexpensive and can cope with a change in the direction of the propeller unit. The boat to which the pedal type propulsion device of the present invention as described above is attached is provided in a hole formed in the bottom of the boat at a front portion, an intermediate portion or a rear portion of the boat such that a tubular body having a shape corresponding to the hole projects into the boat. Since it can be obtained by simply processing an ordinary boat, the manufacturing cost is not particularly high.
