Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-operated bicycle in which pedals provided in water are pedaled, and more particularly to a water-operated bicycle in which the user can observe the water while pedaling.

[0002]

2. Description of the Related Art Conventionally, various types of water boats have been considered and used in various ways depending on the place of use. For example, yachts that utilize wind power and boats that are propelled by an engine are used in large lakes and seas, and boats that use a hand-held turret are widely used and widely used in small lakes and the like. In addition, a boat that pedals with the foot as an element of play is also considered, and it is used in recreation areas. There are also skin diving and scuba diving as ways to enjoy the water.

[0003]

The conventional boat as described above has various problems. For example, wind power has a problem that propulsive force does not occur in the absence of wind, and engine power causes pollution such as exhaust gas and noise, which is against the environmental problems that have recently been shouted. . In addition, hand-operated turrets and foot-operated pedals do not pose a pollution problem, but they are already new and tired. Also, when used in the highly transparent sea, even if you were interested in the seabed or underwater fish, you could not see the situation without special measures, which was unsatisfactory. In addition, the above-mentioned skin diving and scuba diving have problems such as requiring considerable skill and a license in view of safety. An object of the present invention is to solve the above-mentioned problems, to provide a water bicycle that does not cause pollution such as exhaust gas and noise, and that can observe the seabed and underwater while driving. .

[0004]

To achieve the above object, the present invention provides a propulsion drive including at least a float portion, a seat portion, a steering portion including a steering wheel and a rudder, a foot pedal and a propeller. In the water bicycle having a section, the pedal for pedaling is provided so as to be immersed in water when the water bicycle is used. Further, it is characterized in that a window for underwater observation is provided near the handle.

[0005]

The present invention is not only suitable for an ecological society because the pollution of exhaust gas and noise does not occur when the pedal is provided in the water, but also the playfulness is satisfied by pedaling the pedal in the water. Because of the resistance of the body, the amount of exercise required is increased, which is useful for exercising to improve physical strength, maintain physical strength, and slim the body. Also, if you ride alone, you can go in any direction and observe the water freely, which will double the fun.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall external view of a water bicycle according to an embodiment of the present invention. In FIG. 1, 1 is a float part, 2 is a handle, 3 is an underwater observation window, 4 is a seat, 5 is a pedal for pedaling, 6 is a crank, 7 is a propeller (screw), 8
Is a rudder, and 20 is a leg shield (knee cover). Next, the structure of the water bicycle according to the embodiment of the present invention will be described with reference to FIGS. 2 to 4. 2 to 4, the same components as those shown in FIG. 1 are designated by the same reference numerals.

In FIG. 2, the float 1 is for generating the buoyancy of the entire water bicycle. For example, GFRP
(Glass fiber-laminated plastics), Styrofoam, etc. 1 and 2
In the above, the float portion 1 is divided into two parts in front of and behind the seat 4; Leg shield 20
Is for reducing the resistance of water when the speed is increased, and the shape can be changed as necessary and may not be necessary in some cases. First, a configuration example of the steering unit will be described. The handle 2 determines the propulsion direction of the water bicycle by interlocking with the rudder 8. Handle 2
FIG. 3 shows a configuration example in which the ladder 8 and the ladder 8 are interlocked. As shown in FIG. 3, the handle 2 is connected to the rudder 8 via an arm 10 fixed to a shaft 9 and a connecting rod or rod 11 that connects the arm 10 and the ladder 8 to each other. The water bicycle is designed to move in the direction indicated by the arrow. For example, when the handle 2 is turned to the right as shown in (a) in the figure, the arm 10 (fixed to the shaft of the handle) rotates right about the handle shaft as a fulcrum, and accordingly, the connecting rod 11 is moved to the arrow (b). ), The ladder 8 rotates about the fulcrum 12 in the direction of arrow (c). The rotation of the ladder 8 moves the water bicycle to the right. Although an example of the bicycle system is shown as the steering unit here, it is obvious that the present invention is not limited to this, and may be replaced with another known steering device such as a lever.

Next, a structural example of the propulsion drive unit will be described. The foot pedal 5 and the propeller 7 are, for example, as shown in FIG.
They are connected to each other by the structure shown in (a). The timing pulley 13 is rotated by pedaling the foot pedal 5. The rotational driving force of the timing pulley 13 is transmitted to the timing pulley 15 via the timing belt (rubber chain) 14. Timing pulleys 13 and 1
The surface of No. 5 and the timing belt 14 both have gear-like projections, as shown in part in FIG. 4 (a), so that the projections are engaged with each other and slippage does not occur even in water. It has become. Although the timing belt 14 is made of rubber as an example, a metal chain may be used as long as it is durable against rust and does not slip. The rotational driving force of the timing pulley 15 is further changed in direction of the rotary shaft via bevel gears (bevel gears) 16 and 17 meshed with each other, and then the rotary shaft 1 of the propeller 7 is rotated.
8. FIG. 4B shows a view of the drive system as seen from directly above so that the state where the bevel gears 16 and 17 are meshed with each other to transmit the drive force is well understood. In this way
The driving force generated by pedaling the pedal 5 is converted into the rotational force of the propeller, and becomes the propulsive force of the water bicycle. As a result, the user can operate the water bicycle in the same manner as a normal bicycle. It is also possible to adjust the position of the pedal portion according to the body shape of the operator.

Further, the underwater observation window 3 is provided with a transparent plate 19 such as a tempered glass or an acrylic plate on the bottom surface at a position near the steering wheel 2 where the operator can easily see it, for example, a position in front of the steering wheel 2 as shown. Composed. Through this underwater observation window 3, the operator can see the underwater condition while driving, and can observe the underwater condition and the underwater nature in a raw state in a highly transparent sea or lake such as a tourist spot.
For example, you can see beautiful coral reefs and moving fish. The position of the underwater observation window 3 is not limited to that of the embodiment, but may be provided at a position convenient for the operator. Also, by providing a child seat on the rear part of the handle 2, the child can be shown underwater and can be enjoyed by parents and children.

The present invention is characterized in that the center of gravity is lowered and stability is increased because a part of the body is below the water surface. Sinking amount of water bicycle (height of water surface) in the present invention
Is determined by the size and shape of the float portion 1. In general, humans become more anxious when immersed in water up to the height of the chest or higher, so the size and shape of the float may be determined in consideration of the degree of thrill required by the user. In particular, it seems that it is necessary to keep the waist or lower until the lower grades of elementary school.

By changing the shape of the bottom surface of the float 1, the stability of the entire water bicycle can be changed. That is, if the bottom surface is made approximately flat, it becomes stable, and if it is made cylindrical, it becomes unstable and a thrill can be enjoyed. It is important to decide how much the curved surface should take into consideration what kind of people the target user is, for example, for children, make it stable and secure enough safety. There is a need. Further, two water bicycles shown in FIG. 1 can be connected to the left and right to be enjoyed by two people. In that case, for example, two water bicycles may be connected by providing a connecting portion at an appropriate position such as an upper portion of the float 1 of the water bicycle.

[0012]

According to the present invention, a pedal underwater is pedaled, which is particularly pleasing to children who like to play in the water, and the physical strength can be enhanced while playing with the sensation of playing in the water. In addition, as you can peek into the water while moving freely in your favorite direction, the enjoyment doubles in the highly transparent sea or lake,
Especially suitable for use in resort areas. In addition, since you pedal with your feet, noise and exhaust gas are not generated, which also helps prevent pollution.
