JPH01285280A - Sliding machine on snow - Google Patents

Abstract

PURPOSE:To enable a machine to be efficiently moved on snow at a high speed, by permitting a wheel or an endless track having a driving force, to come in contact with the surface of the snow, to obtain a propelling force, and by separating the wheel or the endless track from the snow surface when the propelling force is not needed, to permit the machine to slide with a sliding surface. CONSTITUTION:A main frame 1 and sub frame 2 are connected to each other with a shaft 3, and on the sub frame 2, a saddle 4 and a wheel 5 are retained. In a state that a driver stands on the pad 12 of the main frame 1 and does not rest his weight on the saddle 4, a spring 6 is elongated, and the wheel 5 is separated from a snow surface 10. On the main frame 1, a sliding plate 7 is retained via joints 8, 9. When the wheel is permitted to come in contact with the snow surface to obtain a propelling force, when the driver sits on the saddle 4 and rests his weight on the saddle 4, and his feet are mounted on a pedal 11, and a driving force is applied to the wheel 5. In this state, the spring 6 is shrunk, and the wheel 5 comes in contact with the snow surface 10 and is buried by H.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The simple snow sliding machine of the present invention enables efficient and high speed movement on snow.

Therefore, the snow sliding machine of the present invention is as easy as a bicycle.
There is a high possibility that it will become popular as a footwear in snowy countries.

In addition, it has a kind of sportiness that comes from its comfortable ride, and there is a high possibility that it will become popular as a sports equipment similar to cross-country skiing and contribute to the leisure industry.

(B) Prior Art Conventionally, snowmobiles are used in similar snowy countries. However, since it is equipped with an infinite start that constantly contacts the top surface of 1 g, it does not have the function of sliding when dismounting, and is inferior to the snow sliding machine of the present invention in terms of efficiency. Furthermore, snowmobiles are heavy and cannot be driven manually.

Skis and sleds are examples of snow and gliding machines, but since they do not have their own driving force, they are only capable of sliding and descending, and require other power to climb up.

(C) Problem to be solved by the invention In the conventional technology, a single snow riding device does not have both a propulsion function and a sliding function. (D) No means have been developed to solve the problem. In J, when propulsive force is required on snow, the propulsive force is obtained by bringing wheels or endless tracks with driving force into contact with the snow surface, while on the other hand, when propulsive force is not required. By moving the wheels or endless tracks away from the snow surface and sliding on the sliding surface, both propulsion and sliding functions are achieved.

Hereinafter, the structure 5' will be explained in detail based on typical examples.

FIGS. 1 and 2 show representative examples of the structure of the snowmobile according to the present invention. Figure 1 shows the state in which this riding device is sliding on a sliding surface with its wheels separated from the snow surface.
First, the basic structure will be explained with reference to the diagram. Main frame l and subframe 2.

The subframe 2 is only connected by the shaft 3, and has a degree of freedom to rotate around the shirt 1-3 with respect to the main frame 1.

However, since both ends of the spring 6 are fixed to the main frame 1 and the subframe 2, movement is suppressed.

That is, the subframe 2 holds the wheel 4 and the wheels 5, but the driver does not.

When you are standing on the pad 12 of the main frame L and are not putting your weight on the saddle 4, the spring 6
is elongated, and the wheels 5 are separated from the snow surface 10. In addition, the main frame l has a sliding plate 7, and a dih India 8
and held through 9. Figure 2 shows that this riding device has wheels.

The driver is seated on the saddle 4 and is putting his weight on the saddle 4, which shows a state in which the vehicle is in contact with the snow surface and is gaining propulsion. In addition, the user's feet are placed on pedals 11 to provide driving force to the wheels 5. In this state, the spring 6 is compressed, the wheel 5 is in contact with the snow surface lO, and is buried by an amount H. Here, the amount of H can be yJfi depending on where on the saddle 4 the rider sits. In other words, if you put your weight on the front of the saddle 4 like in PI, the amount of compression of the spring 6 will be small and the amount of force on H will be small.On the other hand, if you put your weight on the back of the saddle 4 like in P2, The amount of compression of the spring 6 is large, and the amount of H is also large, and the handle 13 protrudes forward for a long time, making it easy to shift the weight of the aforementioned Pi and P2. That is, when applying a load of Pl, grip the tip 14 of the handle 13, and when applying a load of P2, grip the tip 14 of the handle 13.
Grip the center part 15 of 3. FIG. 3 shows a perspective view of the present riding device and includes an explanation of the steering mechanism.

The joints 8 and 9 are designed so that the sliding plate 7 has two degrees of freedom in the S and T directions with respect to the main frame l. The movement of the handle 13 is controlled by the lower end 1 of the shirt 1-16.
7 rotation M movement, wire 18 or wire 19
Pull either one of the sliding board 7 or sliding board 2.
1 to make the intended movement in the S and T directions.

The intended movement in the S and T directions referred to here refers to skiing technique in which, when changing direction, one pulls the ski of one foot backward and raises the inside edge of the ski. By combining the movement of the sliding plates 7 and 21 with the left-right movement of the driver's weight, it is possible to change the direction of the riding device.

(E) Effects of the Invention In the present riding device, as shown in FIG. 2, when propulsive force is required, the wheels 5 having the driving force are brought into contact with the snow surface 10 to obtain the propulsive force. On the other hand, when no propulsive force is required, as shown in Fig. 1, the wheels 5 are moved away from the snow surface 10 and slid by the sliding plate 7 at °C, thereby combining the propulsion function and the sliding function. ing. This enables high efficiency and high speed movement.

(F) Other Embodiments In Fig. 4, as another embodiment, engine i
This shows a snowmobile having wheels 105 driven by wheels 105, which differs from the structure in FIG. Intake air filter 152, fuel tank 153. A headlamp 154 is added. The principle is similar to the structure shown in FIG. 1, and when the driver's weight is applied to the pad 112 on the main frame 101, the spring 106 is stretched and the wheel 105 is separated from the snow surface 110. 0
When the weight is on the saddle 104, the spring 106 is compressed and the wheel is on the snow surface 110 as shown at 155.
