Abstract

PURPOSE: To improve the stability for handle control to enable a travel device to be used on both water and land by providing two parallel traveling elements with one of traveling elements connected to a handle and a seat part via a bar, and arranging the traveling elements while providing toe-in and camber. CONSTITUTION: When a user seated on a seat part travels while turning a handle 1 in an advancing direction, front and rear ground traveling elements 7, 7' fit landform because they are freely rotationally connected together across a mounting part. Since the two traveling elements 7, 7', 7' are disposed in the conditions of toe-in and camber, vibration produced during travel and the operation of time handle 1 become smoother. To change direction during travel, the center of gravity of the user's weight is shifted to the right as the handle 1 is operated, so that a right outside bar 11 presses the right traveling element 7' against the surface of grass, while a left outside bar 11 is raised to float the outside traveling element 7' from the ground; the right and left inside bars 11 make opposite movements to that of the outside bar 11, and the right and left traveling elements 7' are both inclined rightward.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a traveling device that can run stably on the ground (on a vehicle) and on water.

<Prior art and its problems> For example, as a motorcycle-type vehicle that runs on snow,
Conventionally, there was something called a snowmobile.

Unlike skis, it has a power source and is widely used because it allows you to enjoy a stable sense of speed, but since it is meant to be driven on snow, it uses wheels similar to those used on motorcycles. Unable to do so, an endless track was used. However, in the case of this endless track, although it can generally be said that it is unsuitable for turning in a short radius, when changing direction in a narrow place, it is necessary to lift a part of the vehicle body. They were forced into the inconvenience of having to leave their homes. In addition, in snowmobiles with such endless tracks, even when changing direction, the entire snow contact surface of the endless track is in contact with the snow surface, so centrifugal force acts on the driver himself. The biggest disadvantage of these types of snowmobiles is that they tend to move in the opposite direction to the direction of rotation, which does not necessarily provide a comfortable ride. Even when moving, the engine had to be driven.

Additionally, sleds have existed since ancient times, but these sleds simply slide on them, and their operation is extremely dependent on the skill of the person riding them. If it is used in the event, a high level of gliding technique is required, making it extremely unsuitable for beginners.

Therefore, in order to solve the above-mentioned problems, the present inventor first proposed a snow traveling device having a rotatable handle and a seat portion, in which a snow sliding board is connected to the handle and the seat portion via a bar. was developed. However, according to this, because it was designed for sliding (driving) on snow, it cannot be used in seasons without snow, and it cannot be used on slopes such as ski resorts where there is no snow. There has been a demand for something that can be used in any season. In the past, there were so-called grass skis that were used in such places, but these were basically ski-like skis with wheels and were mainly used for ski practice. Therefore, it could only be used by those who had some level of skiing ability, and it was not something that everyone could easily use.

On the other hand, there are ships that travel on water,
Water skiing exists as a so-called leisure sport. However, as is already known, this requires extremely advanced technology. For example, one must first stand up on water skis in an unstable position, and from this point of view as well, there was a desire for something that could be used more easily.

Means for Solving the Problems> Therefore, in order to meet the above-mentioned needs, the traveling device according to the present invention is a traveling device having a rotatable handle and a seat portion, in which a bar is connected to the handle and the seat portion for traveling. At least one of the running bodies connected to the handle and the seat is connected to the body or roughly connected to the handle and the seat, and the two running bodies are arranged side by side with toe-in and camber. This improves stability while driving and eliminates vibrations.

<Embodiment> Next, an embodiment of the traveling device according to the present invention will be described based on the drawings. 1 is a handle, and 2 is a seat portion. The handle 1 is rotatably arranged with respect to the seat part 2, and this rotating part is connected to the seat via an angle 4.4' fixed to the handle shaft 3 of the handle. 2, and a coil spring 6 is wound around this shaft 5.

In addition, the seat portion 2 may be made of a spring material itself, or may be made of a hard material without using a spring material, and a cushion material may be placed on top of the base material to absorb shock during driving. It's Nishide. 7.7' is a ground vehicle, and this ground vehicle 7.7' may have many small roller-shaped wheels arranged on the lower surface of a single plate, as shown in FIG. 7, for example. However, it may also be a tracked wheel as shown. Also, among these track wheels 7.7 degrees, sometimes there is only one ground vehicle 7 in front as shown in FIG.
Sometimes there are two as shown in Figure 3. If the ground vehicle 7 is to be one of these, the handle shaft 3 is extended downward from the center of the handle 1, the ground vehicle 7 is pivotally supported on the lower end of the handle shaft 3, and the ground vehicle 7 is This pivoted part is used as a pivot and is arranged so as to be freely rotatable in the vertical direction. In addition, when there are two ground vehicles 7 as shown in FIG. The handle shaft 31Fr is extended to the position of the horizontal member 8, and a 0-shaped angle 9 is fixed to the handle shaft 3.
The horizontal member 81Fr is rotatably held by the horizontal member 81Fr.

On the other hand, the upper end of the second handle shaft 3', which is rotatably connected to the two ground vehicles 7, has a height that reaches the position l of the horizontal member 8, and is fixed to the handle shaft 3 at its upper end. Fix a similar 0-shaped Ashiguru 9', and use this angle 9.
Both ends of the horizontal member 8 are rotatably held by the handle shaft 3, and the angles 9 and 9' of the handle shaft 3 are rotatably connected by the horizontal par 10, thereby transmitting the rotation of the handle 1 to the ground vehicle 7. It is configured to do so. The other ground vehicles 7° are disposed below the seat portion 2, and there are two ground vehicles 7' on the left and right. The connection between the ground vehicle 7' and the seat portion 2 is as follows. That is, as shown in FIGS. 5 and 6, two or more diagonal bars 11 are rotatably arranged diagonally parallel to each other from the bottom surface of the seat portion 2, and the lower ends of the bars 11 are Attachment 12 to the ground vehicle 7'
It is rotatably connected via. Also, when this bar 11 is rotatably connected to the seat part 2, as shown in FIG. The 0 action is the same in both the case of connection at three points and the case of connection at four points as shown in FIG. Furthermore, when the lower end of this bar 11 is connected to the ground vehicle 7', the part connected by the fixture 12 is used as a bridge to allow the ground vehicle 7 to be rotatably connected. still,
In the figure, reference numeral 13 denotes a reinforcing bar 13 which is sandwiched between the front and back sides of the diagonal bar 11 in order to reinforce the diagonal bar 11, and this reinforcing bar 13 is rotatably supported by the outer bar 11. There is. In addition, as shown in Fig. 4, two ground vehicles 7.7.7' are installed in parallel on the left and right as described above.
, 7°, whether they exist on the handle side or on the seat side, they are arranged so that their leading ends face inward, that is, in a toe-in state. The ground vehicle 7.7.7', 7' is, for example, the fifth
As shown in FIG. (camber). According to the experiments conducted by the present inventor, it has been found that the toe-in and camber angles are preferably 26 degrees for toe-in and 3 degrees for camber. Note that the toe-in angle shown in FIG. 4 or the camber angle shown in FIGS. 5 and 6 are somewhat exaggerated in the drawings for ease of understanding.

<Operation of Example Work> Next, the operation of the traveling device according to the present invention will be described. The user lowers his/her back onto the seat portion 2, grips the handle 1, and travels while rotating the handle 1 in the direction of travel. In this case, since the front and rear ground vehicles 7, 7' have their mounting portions rotatably connected to the ridge, they adapt to the terrain. Further, since the two ground vehicles 7.7.7° and 7' are arranged in a toe-in and camber state, the vibrations generated during running and the operation of the handle 1 are smoothed. When attempting to change direction while driving roughly, this is basically done by operating the handle 1 as described above.At the same time as the handle 1 is operated, the person sitting on the seat part 2, for example, changes direction to the right side ( When the center of gravity of the vehicle is moved, the outer bar 11 on the same side of the diagonal bars 11 presses the outer part of the right ground vehicle 7' against the ground (grass surface), and the left bar 11 The outer bar 11 is pulled up, and the 7° outer part of the outer ground vehicle rises from the ground, and the inner bar 11 of both the left and right diagonal bars 11 moves in the opposite direction to the outer bar 11. (As a result, both the left and right ground vehicles 7' end up tilting to the right (
5 and 6), when the load of the seat portion 2 is moved from side to side in this way, the ground vehicle 7' also tilts in that direction, which generally causes the handle shaft to Through this, the direction of the ground vehicle 7 connected to the handle shaft 3 is rotated to the side where the seat portion 2 is inclined, so that it automatically faces in the desired direction of travel. The above description has been about changing the direction to the right, but the same effect can be achieved when changing the direction to the left by moving the center of gravity to the left. In other words, it is similar to the manner and posture when cornering while riding a motorcycle.

<Embodiment 2> In this embodiment, as shown in FIG. 8, a water surface levitation member 14 is provided in place of the ground vehicles 7, 7, 7' and 7' used in Embodiment I. It is preferable that the water surface floating member 14 used here is formed, for example, in the shape of a surfboard and has a certain degree of buoyancy.

Other configurations and functions are the same as those of the example construction.

<Effects of the Invention> As described above, according to the traveling device according to the present invention, in the traveling device having a rotatable handle and a seat portion, a traveling body is connected to the handle and the seat portion via a bar, or the traveling device is connected to the handle and the seat portion through a bar. In contrast, at least one of the running bodies connected to the steering wheel and the seat is parallel to the JsX
Since the two running bodies are arranged side by side with toe-in and camber, the running body below the seat tilts in that direction due to the movement of weight during sliding, and this causes a small radius rotation. It is also easier to install two
By arranging the book's running body in a toe-in state, there will be no slight meandering while sliding, and by arranging the two running bodies side by side in a camber state, it will be able to move smoothly even on slopes. This has the effect of eliminating side-slip when turning, allowing free and quick rotation, and improving the overall stability of steering wheel operation. Furthermore, if a ground vehicle and a water surface floating member are prepared separately, it is possible to use them separately for land and water.
