Description

[Detailed explanation of the idea] [Industrial application field] TECHNICAL FIELD The present invention relates to a rail running vehicle device.

[Conventional technology and its problems]

Conventional vehicle devices of this type run on a single rail held at a predetermined height above the ground by the operator inside the vehicle rotating the pedals, and the vehicle travels on a single rail held at a predetermined height above the ground. In areas with uneven terrain, the influence of the slope of the rail is directly transmitted to the operator through the wheels rolling on the upper surface of the rail, and therefore attitude control cannot be performed, so the operator leans forward or lies on his back. I often felt uncomfortable. Further, when the vehicle body tilts and leans forward, there is a risk that a part of the body may be hit, which is dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rail-running vehicle device in which the above-mentioned problems are solved.

[Means for solving problems]

The present invention includes a running track having a pair of rear wheel rails arranged parallel to each other and at least one front wheel rail interposed between the rear wheel rails, and a wheel that rolls on the front wheel rail. A capsule-type foot-operated vehicle body having a front wheel and a pair of rear wheels rolling on a track for the rear wheels, and the front wheel or the rear wheel being rotationally driven by driving a pedal of a pedal device. In the vehicle device, the front wheel is attached to the vehicle main body so as to be rotatable around a vertical axis, and the front wheel is mounted on a holding frame of the front wheel while rolling against a side surface of the front wheel rail and sandwiching the rail. A prevention guide wheel is attached, and the rear wheel rails are placed higher than the front wheel rails on the upward slope section of the running track, and the front wheel rails are placed higher than the rear wheel rails on the downward slope section of the running track. Further, in the flat part of the running track, there is a difference in height between the front wheel rail and the rear wheel rail, and in the pond in the running track or its vicinity, the front wheel rail is higher than the rear wheel rail. That is.

[Effect]

On uphill sections, the rear wheel rails are set higher than the front wheel rails, and on downhill sections, the front wheel rails are set higher than the rear wheel rails, so the vehicle body is held horizontally in the same way as on flat sections. or the angle of inclination of the vehicle body can be made gentler.

Further, in the flat portion, the front wheel rail and the rear wheel rail have a height difference, so that the vehicle body can be tilted. Further, when entering the pond, the vehicle body assumes a forward lifting position.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1 and 2, reference numeral 25 denotes a running track, which includes a pair of rear wheel rails 2, 2 arranged parallel to each other, and a front wheel interposed between the rear wheel rails 2, 2. It is equipped with a rail 1, and support rods 3 for holding each rail 1, 2, 2 at a predetermined height above the ground. Further, a foot-operated vehicle body 6 having front wheels 4 and rear wheels 5
A pedal device 7 is provided which is operatively connected to the rear wheel 5. Specifically, the pedal device 7 includes:
It consists of an input pedal 8 and a large sprocket 9, and the rotational force generated by the foot pedal of an operator 10 is transmitted to the rear wheels 5, 5 via a chain 11. 12, 12 are sprockets directly connected to the rear wheels 5, 5, and 13... are intermediate sprockets. Note that the pedal device 7 may not be operatively connected to the rear wheel 4, but may be operatively connected to the front wheel 4.

14 is a front bumper, and 15 is a rear bumper, which project forward and rearward, respectively. The front bumper 14 is capable of absorbing impact force by deforming a spring housed in a cylindrical body. front wheel 4
has a caster structure and is rotatable around the vertical axis 16, so that even if the rails 1, 2, 2 are curved, it can run along them. Holding frame 2 for front wheel 4
6 is provided with two anti-falling guide wheels 17 on both sides of the front wheel rail 1, which roll and hold the side surface of the front wheel rail 1. Guide wheels 17, 17 are attached to the lower sides of the rear wheels 5, 5, respectively, and roll on the inner surfaces of the rear wheel rails 2, 2, respectively. The left and right rear wheels 5,5 can be driven only by the driver 10,10 seated on the same side, and the left and right rear wheels 18,
Since 18 is made separate, a differential device is not required. Although not shown, the cam clutch is connected to each rear wheel 5,
5, the rear wheel shaft 18 can be made integral, and the rear wheels 5, 5 may be fixed to both ends thereof.

Therefore, both rails 1, 2, and 2 shall be laid with a relative height difference when viewed from the side, and the first
In the figure, the rear wheel rails 2, 2 are arranged at a slightly higher position. In FIG. 3, the solid lines indicate the rear wheel rails 2, 2, and the dotted lines indicate the front wheel rail 1. In the uphill slope section 19 of the undulating terrain, the front wheel rail 1 is shown, and on the contrary, in the downhill slope section. In 20, the rear wheel rails 2, 2 are laid so as to be relatively lower than the other. Therefore, the vehicle body 6
can be held substantially horizontally, or the inclination angle of the vehicle body 6 can be made gentler. Therefore, the operator 10 can maintain a straight posture at all times while driving, does not lie on his back when on the upward slope section 19, and is prevented from falling backwards. Further, even when the vehicle is on a downward slope 20, the vehicle does not lean forward, and there is no risk of hitting the head on a part of the vehicle body 6. Further, in the flat portion 21, a relative height difference is provided between the two rails 1, 2, and 2, so that the vehicle body 6 can be at an arbitrary inclination angle while traveling.

In FIG. 4, the front wheel rail 1 is provided at a lower position than the rear wheel rail 2, and by laying it in this manner in the upward slope section 19, the vehicle main body 6 can be held in a substantially horizontal position. Figure 5 shows both rails 1, 2, 2.
This shows the state of the vehicle main body 6 while it is running when the heights are the same.

As shown in Figure 7, there is a pond 22 in the middle of the running track 25.
If the vehicle has a vehicle body 6, the front wheel rail 1 is raised higher just before the pond 22 or within the pond 22.
Operator 10
This prevents people from getting splashed with water.

In the above embodiment, the two rails 1, 2, 2 when viewed from above are as shown in FIG. 6, with the rear wheel rails 2, 2 arranged on both sides of one front wheel rail 1. As shown in FIG. 8, two front wheel rails 1, 1 may be arranged between rear wheel rails 2, 2. In this case, it is also preferable to arrange the front wheel rails 1, 1 on the outside, respectively.

Although not shown, it is also preferable to arrange a lifting device such as a chain at the uphill slope section 19 in the middle of the course so that the rider can climb up the slope without stepping on the pedals 8.
Alternatively, for steep downward slopes, it is preferable to provide a lowering device such as a chain or a stationary brake mechanism.

In order to lay the rails 1, 2..., it is possible to lay the rails 1, 2, etc. on a flat area 21 or on an undulating terrain such as a small mountain on the way. By setting the support rods 3 of... to appropriate heights, it is possible to create a circular course with many ups and downs.

In the above embodiment, only the case where two people are riding on the vehicle main body 6 is shown, but the vehicle can be driven by just one person, and can also be applied to a one-person vehicle.

[Effect of idea]

Since the present invention is constructed as described above, it produces the following effects.

The vehicle main body 6 can be held in a substantially horizontal state in both the upward slope section 19 and the downward slope section 20, or the inclination angle can be softened, so that the operator 10 inside the vehicle main body 6 can suddenly lean forward. It is safe because the driver 10 does not suddenly fall on his back, and the ride is extremely comfortable for the operator 10.

In the flat part 21, the front wheel rail 1 and the rear wheel rails 2, 2 have a height difference, and the vehicle body 6 is inclined, and the vehicle body 6 has to be handled with great force, or conversely, the vehicle body 6 has to be handled with great force, or conversely, the vehicle body 6 has to be handled with great force. 8 may become unnecessary, and for the operator 10, the fun is doubled compared to simply orbiting the traveling track 25.

When the vehicle body 6 plunges into the pond 22, it assumes a forward lifting posture, and since the vehicle body 6 is capsule-shaped, the operator 10 does not get splashed with water and there is no fear of his clothes leaking.

Since the front wheels 4 are rotatable around the vertical axis 16, even if the running track 25 is curved, it can be adapted to the curve. Since it is sandwiched between the wheels, it is extremely safe without coming off the running track 25, and it is easy to manufacture and does not require high costs.
