Abstract

(1) The technical field to which the invention belongs

The present invention relates to a one-wheeled bicycle in which a wheel, a frame and a pedal are installed on one rotary shaft, and a saddle is mounted on the top of the frame, and the present invention separates the wheel and the frame from the rotation of the pedal shaft and installs another rotary shaft on the frame. It is a one-wheeled bicycle that installs a pair of cog wheels and rotates the wheel by increasing the rotation of the pedal shaft twice.

(2) Purpose of devising

Independent of the wheel and frame of the one-wheeled bicycle to rotate the pedal shaft to free the rotation of the pedal, the pedal shaft rotation speed is increased by two times to rotate the wheels to get the fast speed of the bicycle, even if the pedal stops rotating the bicycle continues to move forward Bicycle to do.

(3) constitution

The pedals are fixedly installed at both ends of the wheel bicycle wheel, the wheels are installed independent of the rotation of the shaft, and the frame is installed independently of the rotation of the shaft inside the pedal. On the inside of one pedal, a large cog wheel is fixed to the shaft, and on the other side, a free wheel cog is fixed to the wheel, and another rotary shaft connecting the two frames to the upper part of the wheel is installed. A pair of cog wheels is installed to connect the large cog wheels installed on the pedal shaft and the freewheel cog wheels fixed to the wheels with each other by a chain. Install the saddle on the top of the frame, install the brake handle on the saddle, connect it to the brake with steel wires, and install the saddle height adjuster and frame folding device on the frame.

(4) effect of design

The pedal shaft of the bicycle can be freely rotated or stopped, and the pedal can be rotated twice to increase the speed of the bicycle by rotating the wheels, and the bicycle continues to move forward even when the pedal shaft is stopped. It is low and acts as a safe and convenient means of transportation.

The present invention installs the wheel and the frame of the wheel bicycle independently of the rotation of the pedal shaft, the pedal shaft and the wheel rotates independently of each other, and another rotation shaft is installed in the middle of the frame, a pair of different sizes The gears are fixed and connected to the large gear wheels installed on the wheel axle and the free wheel gears fixed on the wheels.The gears are rotated by increasing the speed twice, rotating the wheels and stopping the pedals. It's a bicycle.

In the conventional one-wheeled bicycle used in the circus, the wheels are fixed to the pedal shaft, so the rotation of the pedal shaft and the rotation of the wheels are the same, so that they cannot achieve high speed. It is impossible.

Or to solve the above problems, install the frame high on the wheel axle and the pedal axle on the upper frame of the wheel to connect the cogwheel fixed to the coaxial wheel and the freewheel cogwheel fixed to the wheel with a chain, In this case, since the height of the frame is so high that the bicycle can fall down, it is inadequate to be used as a real vehicle, and it was mainly used in a circus.

The present invention was devised to solve the above problems. The wheel and pedal shafts of the bicycles are on the same axis, but the rotations are installed independently of each other, and the frame of the bicycle is also installed on the same shaft. The bearings are installed independently from the rotation of the pedal shaft without fixing, and another rotation shaft is installed in the middle of the upper side of the frame, and a pair of cog wheels of different sizes are installed there and the gears on both sides of the wheel are installed. The chain can be connected to the chain, and the pedal's rotational force is increased twice to rotate the wheels so that the bicycle can move at high speed even if the pedal is rotated slowly, and the wheel continues to rotate even if the pedal is stopped. It is designed to do that.

In order to achieve the above object, the present invention fixedly installs a large cogwheel (2) on the shaft (1) next to the right side of the wheel (1) on the axis of the wheel, and the freewheel cogwheel (3) on the other side. It is fixed to the wheels and fixed to the pedal (4) on both ends of the shaft. Using the bearings on both sides of the pedals, the frame of the bicycle (5) is installed independently of the rotation of the pedal shaft, and another rotating shaft (6) is installed in the middle of the frame of the upper part of the wheel. After the gears (7, 8) of the fixed to the left and right to install a pair of cog wheels and the wheels (2, 3) installed on the wheel axle are connected to the chain (9 and 9-1). At this time, (7) cogwheel is smaller than (2) cogwheel, and (8) cogwheel is using cogwheel larger than (3) freewheel cogwheel.

The saddle 10 is installed on the top of the frame, but the height adjusting device 11 for adjusting the height of the saddle is installed in the middle of the frame and the frame folding device 12 for folding the saddle when the bicycle is not used.

On the right side of the wheel (on the drawing), the brake 13 is fixed to the wheel and connected to the brake wire 14, and installed upward along the frame and connected to the brake handle 15 installed in the saddle.

The operation of the present invention is as follows. When the pedal shaft of the bicycle is rotated by stepping on the pedal first, the gear wheel (2) fixed to the pedal shaft rotates, and this rotational force is transmitted to the small gear (7) installed on the upper part through the chain (9), and the upper rotating shaft (6). This rotates, and the first speed is increased. This rotational force again rotates another large cogwheel 8 fixed on the same shaft 6, which is transmitted to the freewheel cogwheel 3 fixed to the wheel via another chain 9-1. The wheel is rotated, and the speed is increased again. When the pedal shaft stops rotating, the other wheels are stopped by the freewheel gear (3), and only the wheels continue to rotate independently and the bicycle continues to move forward.

When the speed of the bicycle is to be reduced, the brake handle 15 installed on the saddle is pulled, and the speed is controlled by compressing the brake 13 connected to the brake line 14 by the force.

In addition, by using the saddle height adjusting device (11) installed in the middle of the frame to adjust the height of the saddle according to the height of the user, when not using the bicycle or transport the saddle by loosening the bolt of the frame folding device (12) Fold.

As described above, according to the present invention, by increasing the rotational force of the one-wheeled bicycle pedal shaft twice to obtain the fast speed of the bicycle, even when the pedal shaft is not rotated, the wheel can continue to rotate and the bicycle can move forward. It is possible to secure safety by lowering the height of the entire bicycle, and to control the speed using the brake if necessary.

In addition, the height of the saddle can be adjusted according to the height of the user by using the saddle height adjusting device, so anyone can use it regardless of the size of the height.When not using the bicycle, the saddle is folded by using the frame folding device. Easy to carry and store
