Unicycles are tools that use the muscles of the legs and waist to hold the center of the body and move forward or backward, making it difficult to master the skills of riding a bicycle. There is a situation. Compared to today's bicycles that use the chain to power the rear wheels, the efficiency is less than that of facts, but more than for fitness and riding pleasure.

The present invention is an auxiliary tool for beginners to easily learn the unicycle, and it is equipped with an exercise device that allows the rider to ride the unicycle by adjusting the height of the auxiliary wheel and eventually removing it as the skill is improved. To provide.

If you want to learn unicycle for the first time, grab your hands on a wall or a parallel bar and hold it on your bicycle to practice balancing your body, and then move forward or backward. The person who is good at riding two-wheeled bikes cannot easily learn because they must support their weight on the saddle on the wheel axle.

Therefore, the unicycle exercise device of the present invention installs auxiliary wheels at the front, rear, left and right so that the center of gravity can be centered from side to side until skill is mastered, and if the occupant loses balance and the center of gravity is on the other hand, the resilience depends on the degree. It is to be an effective exercise by working and mitigating shock.

The present invention is to allow the beginners to easily learn the skills by detaching and adjusting the training device equipped with auxiliary wheels in the existing unicycle as follows.

Figure 1 shows a perspective view of the front and rear left and right wheel practice apparatus. The upper frame 7, the lower frame 8, the front and rear frames 9 are coupled to each other, and the auxiliary wheel 10 is connected thereunder, and the exercise device is mounted on the bicycle fork 3 by the mounting holes 11. . Mounting holes 11 can be used to clamp, band, bolts, etc. to be in close contact with the cross-section of the bike fork (3), which is generally oval, a general technique that is widely used in fixing the height of the saddle or pipes Therefore, detailed description is omitted. Initially mounted in a substantially horizontal state with the unicycle wheel (4) can be mounted while gradually raising the height and the structure is easy to finally remove it is desirable. If the stiffness of the upper frame 7 is sufficient to support the load, the lower frame 8 may be omitted, but since the truss shape is generally structurally advantageous, the existence of the lower frame 8 ensures stability. In addition, since the mounting holes 11 must be fastened to both sides of the fork 3 of the bicycle, the upper frame 7 and the lower frame 8 are connected to each other by rivets or bolts, so that the rotational movement of the connecting shaft is free. desirable.

2 and 3 show a side view and a front view of a unicycle, in which front and rear left and right wheel practice devices are installed, respectively. In the conventional two-wheeled bicycle, the power of the pedal is transmitted by the chain, so the movement of the crankshaft and the wheel are separate, but the unicycle has a problem in installing the support directly on the shaft because the shaft and the wheel are integrated. Therefore, it is more advantageous in terms of convenience or structural stability of the detachment or direct installation using the mounting holes 11 in the frame ie bicycle fork (3).

4 is a side view of a caster wheel used as an auxiliary wheel. In general, the wheel shaft and the wheel are installed in the fork, but the caster wheel is free to rotate in the headset 12 connected to the frame, and the center of the caster fork 13 is located in front of the center of the wheel shaft to move in the direction of movement. Since the wheel is always behind the headset and freely turns, it is a universal tool for chairs, carts, beds, shelves, etc. The unicycle should ultimately be free to turn using unicycles, but there are many limitations if the unicycles are fixed to the front and back or to the sides. Therefore, when the caster wheel is mounted as the auxiliary wheel 10 can be free to change direction.

5, 6, 7 and 8 show the front and rear left and right wheel practice apparatus with a shock absorber is installed. In general, when practicing the unicycle, while relying on the handrail or the wall to practice the balance of the body to move slowly. If the center is inclined to one side, it will return to its position by the power of the legs and waist, and if it exceeds the limit, it will not be supported and supported by the reliant hand. At this time, if the center is inclined a lot, when it is inclined by a small force, it is supported by a small force, which requires a large force when first immature, but becomes less and less as it is mastered, and does not need to be supported later. When practicing with the trainer behind you, adjust the strength and strength of your body according to your balance. In the end, even if you let go, you can ride.

While practicing alone, the shock absorber is installed in order to adjust the strength of the center of gravity according to the skill of the exerciser as described above. This is the elasticity of the frame itself, the spring is installed on the lower frame, and the spring on the upper frame. There is a way to install the spring on the wheel head.

Figure 5 shows a side schematic view of the left and right side wheel training apparatus equipped with an elastic frame shock absorber, and as shown in the figure, the frame absorbs the force while the deformation occurs in the shape of a dotted line, and the restoring force by the elasticity of the frame. This action returns you to the original state. At this time, the upper frame 7 and the lower frame 8 is advantageous to be coupled to the fixed end.

Figure 6 shows a side view of the front and rear left and right wheel practice apparatus with a shock absorber lower frame spring (15), a structure that is supported by the restoring force of the spring against the force to fall. The spring may also use springs or air springs.

Fig. 7 shows a side view of the front and rear left and right wheel training apparatus with the headset spring 16 shock absorber, and the force to fall down acts on the upper frame 7, which is attached to the headset 12 (16). ), Which is supported by the restoring force of the spring, which can use spring or air spring.

Figure 8 shows a side view of the front and rear left and right wheel practice apparatus with a shock absorber of the upper frame spring 17, the upper frame spring 17 is bent by the force to fall to the original position by the restoring force to support the structure Bending springs or leaf springs can be used.

By equipping the unicycle with the front and rear left and right wheel training apparatus of the present invention, the restoring force acts according to the strength of the falling force, and the shock is alleviated, so that the beginners can learn the unicycle more easily.
