Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a small, single-seater polka dot vehicle that has a simple configuration and excellent running performance.

(Prior art 41Fi) Recently, a water vehicle has been proposed, which is a single-person boat that rides on a board in a crawling position and sails on the water surface. It is desirable for this water vehicle to be as small and simple in construction as possible for transportation and other handling purposes. The above-mentioned water vehicle is equipped with a thrust device, and a rudder plate is attached to the stern, and a handle is provided at the front of the main body as a means of operating the rudder plate, and a steering force is transmitted from the handle to the rudder plate. The steering force transmission means complicate the construction of the water vehicle.

Furthermore, because the hull is small, people may fall into the water from the hull due to waves, etc., and in this case, there is an inconvenience that the hull travels far away from the person.

(Purpose of the Invention) This invention was made to solve such conventional problems, and the turning performance is fully demonstrated with the fil structure, and the hull protects the boat from people even when they fall into the water. The purpose is to provide a water vehicle that does not travel far and is easy to handle due to its eaves.

(Structure of the Invention) The present invention is a small water vehicle having a plate-shaped hull for one person, and is provided with a Jft advancing gear d protruding from the bottom of the hull, so that the hull turns when no steering force is applied. The keel is curved in the length direction to either the left or right for sailing.

In the above configuration, the steering angle during use is determined by moving the legs placed under the water. Therefore, there is no need for a handle or power transmission means, and the structure is simple and convenient to handle.
Additionally, because the keel of the boat is curved, if a person falls into the water, the boat will return to its original position by cruising in a constant arc.

(Example) In FIGS. 1 and 2, a boat body 1 is formed eccentrically and flatly in the shape of a plate, and its upper surface slopes smoothly backwards, and a person 10 is placed on it holding a handle 14 and lying on his stomach. It is designed to be ridden. The legs protrude behind the stern, and by moving the legs left and right in the water, the resistance is increased and the rudder angle is controlled.

A viewing window 25 that penetrates vertically is formed in front of the viewing window 25, and an air intake 6 for the engine is provided in the upper front part of the viewing window 25.

A fuel tank 30 is provided in the hull 1 above the propulsion device 3, and fuel is supplied from a fuel inlet 31 on the hull 1. Moreover, the air-in-arc 6 opens upward, and air is supplied to the n[advance machine 3] through the vibro 0. Further, water that has entered the air intake 6 is discharged from the self-bath 561.

By shifting the body backward, the user can see the ocean floor through the viewing window 25.

A fender 5 made of a floating body such as a foamed material or an air bag is attached to the front end of the hull 1, and the outer surface of the fender 5 is smoothly continuous with the outer surface of the hull 1. 5 and the hull 1 form a bow portion of the hull.

To attach the fender 5 to the hull 2 (=JG), hooks are provided at appropriate intervals on the edge of the bag covering the fender 5, and these hooks are attached to the corresponding hooks on the hull 1. It is fixed by stopping it.

The hull 1 includes an upper skin 11 and a lower skin 12 made of FRP or the like.
and a core material 13 made of a foamed material or the like covered therewith, in which recesses for viewing windows 25 and the like are formed in advance, and these are combined to form the hull 1. 32 is a starter for the propulsion machine.

As shown in FIGS. 4 and 5, the shape of the bottom 2 is such that the keel 20 is curved in the longitudinal direction at the rear with respect to the center 1i180 of the hull. The bottom of the boat on both sides of the keel 20 is formed to have an inclined surface almost symmetrically with respect to the keel 20, as shown by cutting lines (contour curves) a and b.

In the above configuration, as shown in FIG.
When riding on the boat while crawling on the boat and driving the propulsion device 3, the boat 1 will sail on the water surface, and can turn in any direction by moving the legs. To move the legs, the person 10 simply needs to move the legs from side to side while standing on the hull 1 as shown in Figure 2, making steering extremely easy. . In addition, this configuration does not require a handle or operating force transmission means, so the overall configuration is simple, light in weight, and convenient for transportation and handling.

Furthermore, in the above configuration, since the keel of the boat is curved, when a person falls into the water, the boat will return to its original position by traveling along a certain circular arc trajectory according to the curved surface of the keel. It's coming.

(Effects of the Invention) As explained above, since this invention has a curved keel, if a person falls into the water, the boat body will turn and return, so only the boat body can sail far away. There is no risk of it running away.
