Description

Flying wing type body-building training device

Technical Field

The invention relates to medical auxiliary equipment, in particular to a flying wing type fitness trainer.

Background

In order to train the balance ability, endurance and the ability to keep a clear head of a human body in the air, some training apparatuses are commonly used, but at present, most of the training apparatuses are in a single circle mode, the waist of the human body is used as a center to rotate in one to three dimensions, a trainer is fixed on the apparatus to passively rotate, and the endurance is adapted and trained under the condition of rotation, for example, Chinese patents with publication numbers of CN2748113Y and CN 201239461Y. The disadvantages of this passive single-turn mode are: firstly, the training difficulty is high, a beginner is easy to feel nausea and dizziness, the beginner is not easy to get hands, the training effect is not good, the popularization is not realized, and the application audience is narrow; secondly, the rotary radius is large, the risk is high, and the safety is poor; and thirdly, the training mode is single, boring and not strong, the passive rotation cannot carry out flight entertainment experience, and the muscles of the four limbs cannot be exercised.

Disclosure of Invention

The invention aims to improve the defects of the prior art, and provides a flying wing type fitness trainer which can be suitable for beginners training the air balance capacity and the durability, has strong safety, interest and entertainment, can train the air balance capacity and the muscle of four limbs of a human body at the same time, and is suitable for wider training groups.

The technical scheme provided by the invention is as follows: a flying wing type fitness trainer comprises a base, a track limiting seat, a left-right overturning track and a front-back overturning supporting arm, wherein the track limiting seat is installed on the base; the front part and the rear part of the front and rear overturning supporting arms are respectively connected with a first supporting part and a second supporting part which are used for supporting the upper limbs and the lower limbs of the human body.

The invention abandons the traditional mode of training the balance force in the air through single rotation, and because the human body is supported on the front and back overturning supporting arms through the first supporting part and the second supporting part which are used for supporting the upper limbs and the lower limbs of the human body, and the front and back overturning supporting arms can swing in the front and back direction around the mounting shaft, the human body is in a pronation posture on the trainer and can swing back and forth in a seesaw mode under the control of the upper limbs and the lower limbs; the front and back overturning supporting arms are positioned at two sides of the left and right overturning tracks, and the left and right overturning tracks can swing in a circular arc shape in the left and right directions on the track limiting seat by the left and right force of a human body; therefore, the human body can swing back and forth and left and right under the action of active force, and after the front rear overturning supporting arm and the left and right overturning tracks swing, the human body adapts to and controls the swinging under the inertia action of the swinging force, thereby training the air balance force of the human body. Because the human body is in a horizontal bending posture during training, the traditional windmill type rotation with a single turn is not adopted, the height of the human body from the ground is smaller, the height of the base is smaller, on one hand, the trainer can conveniently go up and down the trainer, on the other hand, the safety is greatly improved, the fear psychology of the trainer can be reduced, beginners can also participate in training, and the device is quick to take effect due to smaller difficulty and has wider application range; the swing type training in the front-back direction and the left-right direction can simulate the flying postures of the paraglider and the wing, is convenient for a trainer to carry out simulated training of the sports, has strong interest and entertainment, is matched with VR equipment for use, can also carry out simulated training and game live-action experience, and improves the immersion feeling of a user; meanwhile, balance control is performed due to the fact that four limbs of a human body exert strength, active entertainment training is achieved, muscles of the four limbs can be exercised, and muscle training of the four limbs is performed while the balance force in the air is trained.
