Description

  The present invention relates to a human-powered propulsion device for a water vehicle such as a small boat.

  Originally, Japanese boat dredging was used as a human-powered propulsion device. Japanese boat dredgers are often difficult to operate, and unskilled personnel have many difficulties, such as detaching the dredger from the boat and falling to the surface of the water if operated incorrectly. Boat oars, etc., require a rotating operation that raises the tip of the oar to the surface of the water during operation, and the stability at hand is poor and the efficiency is low. Inexperienced people require skill.

According to the prior application public information, a fixed type has been devised, but since the 3, 9, and 5 parts are fixed in a triangular structure, it seems that the tip cannot rise from the surface of the water, and the hull turns. Difficult points can be considered.
Japanese Patent Laid-Open No. 7-52883

  The present invention intends to solve the above problems. The propellers (eg, dredgers) come off the hull, the balance of the oars is poor, the efficiency is low, and the dredgers are heavy and difficult to handle, and the operation requires skill. The above solution is the purpose.

As an operation method that does not require skill in the first problem, the propulsion blades exert a propulsive force by holding the handle portion of the operation rod and moving it left and right. Stability can be ensured by connecting the rope to the bottom of the ship in the middle of the control rod. The weight is reduced by using stainless steel plate and aluminum material.
The prevention of dredging from the hull is solved by using a rotating shaft for coupling. It has a hull turning method, an operation rod handle, and can be turned by an elliptical rotation operation based on a stable rope.

  The above device makes it easy for anyone to operate the propeller. This will avoid the danger of drifting in the case of engine failure.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a side view of the present invention. This will be described with reference to FIG. The operating rod is fixed to the regulating box 4 with a screw metal, and the regulating box 4 is penetrated in a cross shape by the rotating shaft 5 together with the operating rod 1. The blade fixing metal 7 is also penetrated inside the box 4 by the rotating shaft 5 and is connected through the operating rod 1 and the rotating shaft 5. The propulsion wing is passed through the hull and the control rod. The fixed hardware 2 is fixed to the hull by a fixing screw 9. The wing fixing hardware 7 can be rotated by half in the regulation box. The tip of the fixed hardware 7 is connected to the blade adjusting spring 6 at the operating rod 1 portion. The propulsion blade 8 is kept in a straight line with the operation rod 1 by the attractive force of the blade adjustment spring 6.

  FIG. 2 is a plan view of the propulsion blade. The operation rod and propeller blade are kept straight. During operation, the wing 8 moves at an angle of 50 degrees with respect to the lines 3B-B2. FIG. 3 is a plan perspective enlarged view of the regulation box 4. The propulsion wing portion 8 shows a state when the handle 11 portion of the operating rod 1 is pushed to the side A in FIG. When the handle 11 is pushed in the A direction, the restriction box 4 and the blade 8 start to move to the A2 side. When the movement starts, the blade 8 starts to move to the A side, water resistance is generated on the C side of the blade 8, and water pressure is generated on the blade. The water is pushed back to the C side, generating propulsion. The blade angle is regulated at an angle of 50 degrees with respect to the line B-B2, and the blade fixing hardware 7 is regulated at the corner surface in the box, and the angle is maintained. Propulsive force is exerted by repeating the above reciprocating action. The wing adjustment spring adjusts the wing and the operating rod in a straight line state at the start and end of the movement of the wing 8.

  FIG. 4 is a cross-sectional view of the restriction box 4. The regulation box 4 is best streamlined and requires the use of metal. A cylindrical tube is fixed in parallel with the operation rod. A blade fixing metal 7 is installed in the middle, and is penetrated and connected by the rotating shaft 5. The restriction box 4 serves as an element for adjusting the angle of the wing fixing metal 7 with a square face. The operation rod 1 is fastened and fixed to the regulation box 4 with a screw metal.

Claims (2)

  A long operating rod is coupled to the rear of the hull with a metal rotating shaft and can be rotated. The control box is fixed to the tip of the operation rod. The box is made of metal and has a cylindrical oval shape. The propeller blade fixing rod can be inserted into the inner core portion of the regulation box, and the inner core portion can be fixed through and rotated halfway with a rotating shaft metal. The fixed hardware can be regulated at an angle of about 50 degrees with respect to the straight line of the operation rod at the corner of the inner surface of the regulation box that allows the rotation axis to rotate halfway around the center of the regulation box. The tip of the fixed rod is connected to the operation rod portion using a coil spring. The propulsion blade is kept in line with the control rod by the attractive force of the coil spring. The above configuration is an element of propulsion.   The propulsion blades described above are installed in parallel with the water surface, and the propulsion blades are formed in a rectangular or elliptical shape, so that the propulsive force can be exerted even when the water depth is shallow. The propulsion has an operating rod handle and is operated to the left and right of the hull. The wing part is regulated at an angle of 50 degrees to the left and right, and is operated to the left and right with an operation rotary shaft as the center by an operating rod. This can be promoted. The turn is a right turn by holding the operation handle, pushing it to the left with respect to the front of the hull, pushing it down, turning it back to the right, and pushing it repeatedly. When the handle is pushed down, the propulsion wing rises and the thrust is lost. The reverse operation described above results in a left turn. If a rope is attached to the operating rod and connected to the hull, the stability of the propulsion wing will be maintained.
