Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rudder operation grip for kayaks, canoes and small leisure boats.

[0002]

[Prior art]

 Conventionally, in this type of device, as shown in FIGS. 3 and 4, a rudder device is provided at the rear portion of the boat 30, and the rudder plate 31 of the rudder device is suitable for the length and draft of the boat 30. The rudder shaft 32 is vertically pivoted to the front end of the rudder plate 31 depending on the area, and an arm called a balance 33 is pivotally attached to the upper part of the rudder shaft 32 in a T-shape, and rotated to the stern of the boat 30. It was freely distributed.

Cables 34 and 35 are locked at both ends of the balance 33. The cable 34 is passed through port lead holes 37, 38, 39 and 40, and the cable 35 is connected to starboard lead holes 37 ′ and 38 ′. , 39 ', 40' are connected through the ends of the ropes 34, 35, and the endless (so-called link-shaped) remains loose.

The rudder blade 31 has a rudder angle taken according to the traveling direction of the boat 30, rather, it is swept and swaying, and when a direction change is necessary, one side port can be pulled by hand. To change direction.

Further, in order to maintain the needle-holding property, the boat 30 is provided with a skeg 41 having an appropriate area at the center rear part of the ship bottom.

[0006]

[Problems to be solved by the device]

 As described in the prior art, if the endless mechanism is used with the rope loosened, the steering operation can be steered, but the rudder center operation cannot be performed.When the puller is released, the rudder blade advances the boat. It just followed the direction and returned, and did not play the role of maintaining the needle retention property, but was meandering. When a straight line is required, a skeg is required, and in such a small boat, the protrusion is a hindrance when traveling, propulsion resistance, the weight as an additional item is increased, and it is wasted. However, it had the problem of poor maneuverability.

The present invention has been made in view of the above problems of the conventional technology, and its purpose is to improve the operability while maintaining the needle keeping property of the boat when going straight. It aims to provide something good.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an elastic body in a part of the rope of each port, keeps the extension tension of the starboard and port side in balance, and always keeps the rudder plate in line with the center line of the boat to steer the vehicle. When the control lever is required, the steering levers on each port are gripped to steer in the required direction and at the required angle. When the control levers are released, the rudder blade returns to the center of the hull with elastic force.

[0009]

[Action]

 This device is provided with an elastic body in a part of the rope to keep the tension on the starboard and port sides in balance, and the rudder plate always matches the center line of the boat. Is divided into starboard and port, and acts as a skeg. In addition, for the flow of water or wind, the tension can be adjusted with the adjusting screw, and the rudder center can be set by the rudder and fine adjustment. When steered, by appropriately grasping the lever on one side of the boat, the elastic body on the other side extends and gives an appropriate angle to the rudder blade, and the boat turns. When the grip of the operation lever on one side is stopped, the rudder blade returns to the center of the boat with elastic force, the boat goes straight, and the needle keeping property can be maintained.

[0010]

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, a rudder device is provided at the rear of the boat 6, and the rudder plate 1 of the rudder device is used for adjusting the length of the boat 6 and the draft. The rudder shaft 2 is vertically pivoted to the front end of the rudder blade 1, and an arm called a balance 3 is pivotally attached to the upper part of the rudder rod 2 in a T-shape so that the boat 6 It is rotatably mounted on the stern.

One end of the elastic body 9 is fixed to both ends of the balance 3, and the rope 4 is locked to the other end. The rope 4 is passed through the lead holes 7 and 8 on both sides, and the rope 4 is , Is locked at the tip (point of action) of the operating lever 11 of the grip 10.

The grip 11 is erected substantially vertically on the boat 6 at appropriate positions on both sides of the seat 5, and the stopper 12 of the operating lever 11 is fitted therein.

The operating lever 11 has a fulcrum near the stopper 12, and the rudder blade 1 is angled on the starboard and port sides by gripping the force point 14 with each hand.

An adjusting screw 15 for adjusting the extension tension of the elastic body 9 is provided on the side of the operating point of the operating lever 11 so that the starboard and port side can be finely adjusted.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. This device is provided with an elastic body on a part of each port line to keep the tension on the starboard and port side balanced, and the rudder plate always matches the center line of the boat, and when steering is required, The steering lever is steered in the required direction by the required angle, and when the operating lever is released, the rudder plate returns to the center of the hull with elastic force, maintaining the needle-holding ability and manipulating the steering lever in the desired direction. Steering is good because the boat can be steered simply by grasping or releasing it, and the boat moves in accordance with human senses. There is also a sense of security that the rudder blade returns to the center of the boat when the operating lever is released.
