BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear wheel levitation device for an automatic track bicycle which is used in a disaster or during patrol inspection of a track.

[0002]

2. Description of the Related Art Conventionally, an automatic bicycle which is used for security and patrol inspection in the event of a disaster and runs on a track in order to improve efficiency in operating personnel is now known.

[0003]

The above-described conventionally known and used track illumination automatic bicycle lighting device uses a battery type or a generator as a power source.

However, the battery type has a lot of trouble to charge the battery before using it, and moreover, it is seriously damaged. Furthermore, when the generator is used as a power source for lighting, it is inconvenient when the vehicle is changed in direction because it requires a lot of time for transportation and a large total weight.

[0005]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention uses a power engine incorporating a lamp coil for driving an automatic track bicycle in order to solve these problems. In addition to connecting to the light to illuminate the vehicle while it is running, when the vehicle is stopped, the rear wheels are laid horizontally on the bogie to provide arm members with one end fixed to each end of the shaft. The present invention provides a rear wheel levitation device for an orbital automatic bicycle, which is operated by an operating rod attached to the pedestal so as to oscillate and stand up, and the bogie and the rear wheel are levitated, and the rear wheel is idly rotated to illuminate and work. .

[0006]

The present invention drives the power engine mounted on the rear side of the bogie 1a to transmit the rotation to the shaft 7 of the rear wheel 3 supported by the bearing body 5 of the bogie 1a through the sprocket 12 and the chain 13. While traveling on the rail R and turning on the light 10 by driving the power engine to perform patrol such as disaster security, the light 10 goes out when the running automatic bicycle stops. At that time, if the light 10 goes out, it becomes impossible to work in the disaster position. Therefore, when performing the work by obtaining illumination, when the rotation is transmitted to the shaft 17 supported by the carriage 1a by the operation of the operating rod 18 supported by the stopper pin 20 provided on the carriage 1a, the shaft 17 rotates. Then, by this rotation, the arm member 16 axially supported by the tip of the flanged trochanter 15 fixed to both ends of the shaft 17 is swung along the rail R, and the arm member 1
6 is erected so that the rear wheel 3 of the carriage 1a is levitated from the rail R, and at this levitated position, the operating rod 18 is fixed by a locking member 19 so as to keep it in an upright state. Further, when the power engine 11 is driven and rotated while the rear wheel 3 is levitated, the rear wheel 3 idles, so that the drive of the power engine 11 can be illuminated by the light 10 in the same state as when the vehicle is running. After the work is finished, the rear wheel 3 is placed on the rail R by the operation of the actuating rod 18, so that the vehicle can travel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a rear wheel levitation device for an automatic track bicycle according to the present invention, which will be specifically described below with reference to the drawings.

Reference numeral 1 denotes an automatic bicycle main body. The main body 1 has front and rear wheels 2 provided on a shaft 6 supported by a bearing 4 and a rear wheel 3 provided on a shaft 7 supported by a bearing 5. The trolley 1a, the frame 1b having the passenger seat 9 mounted on the trolley 1a, and one end fixed to the front position of the trolley 1a and tilted toward the rear part, and the handle bar 8 is horizontally provided at the upper end. In addition, the frame 1c is provided with the illumination light 10 attached thereto.

A power engine 11 incorporating a lamp coil is mounted on the rear portion of the truck 1a, and a sprocket 12 provided on the output shaft of the power engine 11 is attached to the chain 13.
The rotation is transmitted to the rear wheel 3 by the drive of the power engine 11 by connecting to the sprocket 14 provided on the shaft 7 of the rear wheel 3 supported by the bearing body 5 on the bogie 1a via.

A bearing member is provided at an inner position slightly apart from the rear wheel shaft 7 of the truck 1a, and an arm member having a flanged rotator 15 pivotally supported at both ends of a shaft 17 supported by the bearing member. By fixing one end of 16 in correspondence with the rail R, and further by fixing one end of the operating rod 18 on one side of the arm member 16 of the shaft 17, by operating the operating rod 18,
The shaft 17 supported by the bearing body is pivoted, and the arm member 16 which pivotally supports the trochanter 15 with a collar is rocked along the rail R, so that the arm member 16 moves on the rail R by this rocking action. The cart 1a is raised by the arm member 16 to float. At this time, the operating rod 18 is in a floating position and is fixed by an appropriate fixing means such as a locking member 19 provided on the frame 1b. Further, during normal traveling, the stopper pin 20 provided on the carriage 1a receives the stopper.

At the center of gravity of the trolley 1a, a support rod 21 for levitating the trolley 1a to change its direction is provided.
Is fixedly provided at one end of a shaft 22 supported by a bearing body, and an operating rod 23 is attached to the other end of the shaft 22, and the operating rod 23 is operated to support the supporting rod 21 on the sleeper 24 between the rails R.
And the main body 1 is levitated by the support rods 21 and the support rods 21 are rotated while the operation rods 23 are held.
Further, after the direction of the main body 1 is changed, the operating rod 23 is received and supported by the receiving pin 25 extending from the carriage 1a.

[0012]

As described above, the rear wheel levitation device for a track automatic bicycle according to the present invention is provided at both ends of a shaft which is borne by bearings on the inner side slightly apart from the rear wheel shaft arranged on the trolley.
Fix one end of each arm member corresponding to the rail, and attach one end of the operating rod that gives swing to the arm member to one side of the arm member, and operate this operating rod to attach the rail to the arm member. By swinging along the rails and standing up on the rails, the bogie and rear wheels are levitated from the rails, and the rear wheels run idle when the power engine is driven.Easy ascent and descent by the action of the operating rod. Further, the floating wheels of the rear wheels have the effect that sufficient light can be obtained from the lights for the work at the stop position.
