Description

Multi-functional squatting and standing body-building device

Technical Field

The invention relates to the technical field of fitness equipment, in particular to a multi-functional squatting and standing fitness device with various motion types, which can assist different types of squatting and standing exercises to meet different exercise requirements and further improve the training effect of the squatting and standing exercises.

Background

According to studies, it has been shown that the main cause of back pain is caused by the weakness of the muscle strength near the spine, which is unable to properly bear the weight of the body, and therefore, the symptoms of lower back pain can be avoided or alleviated if proper exercise is performed to enhance the muscle strength of the abdomen and trunk. Furthermore, the center of gravity of the human body including the ankle, the knee, the hip joint and the lumbar spine all affect each other, so that the knee joint is inflamed and injured due to the factors such as inward rotation or outward rotation of the hip joint, over-bending or over-straightening of the lumbar spine, and too far bending of the hip. In addition, the muscle is the active element controlling the movement of the joint, and the joint can move only when the muscle contracts, and if the muscle control capability is poor, the joint can be painful.

Therefore, the young people should do some simple exercises to strengthen muscles, bones, ligaments and joints after long-term accumulation so as to prevent the early occurrence of knee bending and waist bending. These maintenance exercises can maintain the flexibility of the joints and increase the strength and endurance of the knee muscles, especially the quadriceps femoris and the muscle strength in front of the thighs. In various exercises, the squat and stand exercises are also called deep squat and half squat, which can provide the training of muscle strength, bones, joints and the like of the trunk, the lumbar, the lower abdomen, the thighs and have great effect on overcoming the knee bending and the waist bending.

When the user performs the squat and stand exercise, the user usually bends the knees to a certain degree by the self weight and then restores the standing posture, so that in order to avoid the exercise injury, the beginner or the user with insufficient thigh muscle strength can hold the table top or the object with the hands to assist in supporting the body weight, however, the conventional method cannot really assist the user in the squat and stand exercise. In addition, the squatting and standing posture needs the thigh muscle force to be applied together with the sum of the abdominal muscles and the trunk dorsal muscles, excessive stress is concentrated on knees or thighs when the force is improperly applied or the posture is incorrect in the up-and-down process, and the knee abrasion or the thigh muscle strain can be easily caused if the actions are improper, even the future walking capability can be influenced, and the injury of the knees or the thigh muscles can not be harmed by the people;

although, there are many kinds of exercise equipments developed in the industry with the function of squatting or standing, for example, in the publication of our national patent No. 313866, the user stands on a foot tube pivoted on the support, and the handle pivoted on the support can drive the seat cushion and the foot tube synchronously.

Furthermore, the existing squatting and standing equipment usually has only a single use status, but the users have different body types, different physical abilities, and even different training purposes, so the exercise amount and exercise intensity are different when performing the squatting and standing exercise.

Accordingly, the present inventors have made extensive studies on the above-mentioned problem of monotonous functions, and have conducted many years of research, development and manufacturing experiences in the related industries to actively seek solutions, and have finally succeeded in developing a multi-functional squat-stand exercise machine through continuous research and trial work, so as to solve the inconvenience and trouble caused by the fact that the existing squat-stand equipment cannot meet different exercise requirements.
