Description

[Detailed Description of the Invention] The present invention relates to a bicycle slope running device.

A bicycle is a bicycle that is operated by manually pedaling, rotating the front gear fixed to the pedal shaft, transmitting this rotation to the rear gear via a chain, and rotating the rear wheel fixed to the rear gear shaft. It is. Therefore, since the driving source is human power, it is difficult to run on a slope.

In order to enable this slope driving, attempts have been made to install small internal combustion engines or electric engines, but the weight of each engine and its fuel increases the weight of the vehicle, making it difficult to drive manually on flat roads. west,
In order to support the weight of each engine and its fuel, the vehicle body had to be made strong, and the concept of the vehicle went beyond the concept of a bicycle and belonged to the concept of a so-called motorcycle. In addition, a so-called transmission device was provided in which the rear gear was formed into multiple pieces with different diameters and the gears used to stretch the chain were changed, but in the end, the drive source was human power, and it was not very effective on steep slopes. However, the structure is complicated, the manufacturing cost is high, and there are many failures.

SUMMARY OF THE INVENTION In view of the conventional problems, an object of the present invention is to provide a device for effectively driving a bicycle on a slope with a simple structure.

The purpose of this invention is to attach a motor to the drive part of a bicycle, bury a power supply rail in the road surface of a slope, attach a suspension pipe to the bicycle that has a built-in electric wire to connect to the motor, and a contact point at the bottom end. This is achieved by providing a bicycle slope running device in which the contacts are brought into contact with the power supply rail.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figure 1 is a schematic diagram showing the basic principle of the present invention.
A power supply rail 2 is buried in the road surface 1 of the slope, and a bicycle 3
The motor 4 attached to the drive unit 31 of the bicycle 3
It rotates by receiving power through a suspension pipe 5 attached to the holder.

As shown in FIG. 2, the power supply rail 2 is fixed in a hollow pedestal 6 made of concrete or the like and buried in the road surface 1 of the slope. A ceiling opening 61 is opened in the center of the frame 6 for the suspension pipe 5 to pass through, and the width of the ceiling opening 61 is larger than the width of the tire 32 of the bicycle 3 so that the tire 32 does not fall off. It is narrowly formed. When the ceiling 61 is opened in the pedestal 6, rainwater will flow in from the ceiling 61, so a notch 62 facing upward is formed on the side of the ceiling 61.
A power supply rail 2 is fixed thereto to prevent contact with rainwater. Furthermore, a bottom groove 63 is provided at the bottom of the pedestal 6 for drainage of rainwater that has flowed in.

The suspension pipe 5 has a contact 51 that comes into contact with the power supply rail 5 at its lower end, and has a built-in electric wire 52 that connects the contact 51 and the motor 4 . This suspension pipe 5 has a shaft 53 attached to a connecting pipe 35 between a handlebar pipe 33 and a saddle pipe 34 of the bicycle 3.
It is rotatably attached to the connecting pipe 35, and its position can be fixed by a hook 36 provided on the connecting pipe 35. Furthermore, wheels 54 are provided at the lower end and run in the bottom groove 63 of the pedestal 6 to guide and support the suspension pipe 5. In addition, in order to cope with the horizontal shaking of the bicycle 3, the suspension pipe 5 may be made of a flexible material, or may be made of a flexible material.
It is desirable to provide a bellows-shaped cushion member or the like in the middle.

The motor 4 is attached to the drive unit 31 of the bicycle 3 and is rotated by power obtained from the power rail 2 via the contact 51 of the suspension pipe 5 and the electric wire 52.
Driving force is applied to the drive unit 31 of the bicycle 3. As a means for applying the driving force, as shown in FIG. 4, a gear 42 is aligned with the motor shaft 41 of the motor 4, and this gear 42 is configured to mesh with the chain 37, or as shown in FIG. It is conceivable to configure the motor shaft 41 to be fixed to the rear gear shaft 38 as shown in FIG. In any case, when the bicycle 3 is running on a flat road, the motor shaft 41 and the chain 37 or the rear gear shaft 38 should be
It is desirable to configure the system so that it is free. This freeing structure uses an appropriate mechanism such as a known clutch mechanism.

When riding this bicycle 3 on a flat road,
The suspension pipe 5 is tilted toward the chain case 39 of the bicycle 3, locked with a hook 36, and the bicycle is pedaled like a normal bicycle. By configuring the motor shaft 41 and the chain 37 or the rear gear shaft 38 freely, the existence of the motor 4 does not add to the pedaling process, which is no different from adding to the running of a normal bicycle.

When traveling on a slope, the suspension pipe 5 is held upright and secured to the hook 36, its lower end is placed inside the frame 6, and the contact 51 is brought into contact with the power supply rail 2 to rotate the wheels 54. It is supported in the bottom groove 63. In this state, from the power rail 2 to the contact 51 and the electric wire 5
Power is supplied to the motor 4 via the motor 2, and the motor 4 rotates. The rotation of motor 4 is the rotation of bicycle 3
The bicycle 3 travels even without pedaling.

In addition to the above embodiments, the suspension pipe 5 may be attached to the rear cargo bed of the bicycle 3, the chain case 39, etc., or the motor 4 may be attached to the drive unit 31 of the bicycle 3. , the motor 4 may be meshed with the rear gear via a gear.

Furthermore, the present invention is not limited to two-wheeled vehicles that run by pedals, but can also be applied to vehicles that run by other crank mechanisms, foldable vehicles, tricycles, four-wheeled vehicles, etc. .

As described above, the present invention has the effect of enabling a bicycle to run on a slope with an extremely simple structure.
