The protecting handle 5 is a device for protecting the rider's safety, corresponding to the extension of the arms of the rider, which allows a connection with a certain elasticity to be established between the rider and the bicycle, and allows the rider to bend down no longer to hold the saddle, thus protecting the rider. The elastic body 52 can give a certain self-correction space for the rider, so that the rider can self-adjust the balance state at any time, and if the rider cannot self-adjust the balance state, the elastic body is pulled to the limit to drive the protector to apply external force for intervention, and the balance position is returned to avoid bringing the protector and the rider upside down; and the exercise amount of the protectors can be reduced by the protection handle 5, and the physical expenditure is reduced.
The working principle of the invention is as follows: in use, the rear wheel of the bicycle is placed on the adjusting plate 12 of the stand 1 of the learner, and the practitioner directly rides on the bicycle to learn or practice riding the bicycle. The protector can hold the protecting handle 5 to further ensure the safety of the rider.
The key skill of the bicycle is to keep the balance state of the bicycle all the time, the balance state is completed by adjusting and controlling the handle bar of the bicycle through the subconscious sense formed by the cyclist in the process of driving the bicycle, namely, when the brain senses that the bicycle is inclined or tends to be inclined, the condition reflection is formed rapidly, the limbs are commanded to make corresponding actions, and the handle bar of the bicycle is adjusted, so that the bicycle is kept to stably run forwards. The key to learning to ride a bicycle for children is to create this subconscious through continuous training, so the exerciser should first begin to exercise from controlling the handlebars. The training function cannot be realized by directly using a bicycle or using various training appliances except the invention, so that the ability can only be formed by passively removing food retention through a large amount of training. The invention can truly simulate the whole action process of riding the bicycle, and simulate the cycle process of 'losing balance', 'rotating the handlebar', 'realizing balance' … …, so as to promote conditional reflection to send out control instructions to limbs, further achieve correct control to the handlebar, and simultaneously realize coordination and coordination skills and skills of all parts of the body, and master basic skills of riding the bicycle.
Children use the invention to learn to ride a bicycle in two phases of learning. The first stage is that the child is forced to the bicycle body by the training partner when learning to ride the bicycle, so that the bicycle is artificially manufactured to lose its balance to the left or right, and the training partner is required to rotate the handle bar in the same direction. And then applying external force in the opposite direction with proper frequency to complete the exercise. The training partner circularly repeats the actions, the repeated degree and frequency of each repetition are properly changed, and the repeated training enables a learner to establish the condition reflection of 'losing balance', 'turning the handlebar', 'realizing balance', thereby achieving the purpose of correspondingly and rapidly adjusting the handlebar according to the degree and frequency of losing balance. The second stage is that after the exerciser establishes the condition reflection, an improved learner with a semi-cylinder is additionally arranged on the base to further simulate the riding state for exercise, the semi-cylinder approximates to a bicycle tire, the exerciser can exercise in situ under the condition of being more similar to reality, the exercise difficulty is increased, and the capability is further improved. After the exercise in the two stages, the exerciser can exercise riding under the protection and the help of the protector. The protecting handle is fixed under the saddle of the bicycle, so that a user can stand up the body, and the protecting range is wider and safer.
In summary, the beneficial effects of the invention are as follows: the bicycle can be learned in a specific place in a fully-simulated mode, is suitable for more places, saves space, can safely and effectively help children or other people to learn to ride the bicycle quickly, and can also be suitable for physical training of cyclists.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, modifications and additions may be made to the present invention without departing from the invention, such as changing the base to a cuboid-shaped laminated floor, mounting the damper on the base, and attaching elastic tie bars on both sides. Or hanging the bicycle off the ground through a bracket, etc. These improvements and additions are made on the basis of the invention's realization that a bicycle can be learned in a fully simulated manner in a particular location, and are also considered to be within the scope of the invention.
