Description

squat assist device

technical field

The invention relates to the technical field of fitness equipment, in particular to a squat auxiliary device with a simple structure, which can improve the training effect and is convenient for users to operate, thereby achieving the effect of reducing costs.

Background technique

Press, due to lack of exercise, modern people generally suffer from soreness, pain or stiffness in the waist, lower back and knees, making the feet and waist unable to effectively support the trunk, changing the body's support center of gravity, especially for the elderly to adjust the body The center of gravity will bend the knees and bend the waist. After years of accumulation, it will cause them to be unable to stand for a long time or even stand upright. This will not only affect the posture, but also affect the flexibility of movement. And cause different diseases in the body. The main cause of back pain is that the muscles near the spine are too weak to properly bear the weight of the body;

Therefore, if there are appropriate exercises to strengthen the muscles of the abdomen, back and trunk, the symptoms of low back pain can be avoided or reduced. In addition, muscles are the active components that control joint movement. Only when muscles contract can joints move. If muscle control is poor, joints will also ache. Therefore, long-term strengthening exercises for muscles, bones, ligaments, and joints can prevent the early appearance of bent knees, bending over, and hunchback. These maintenance exercises can maintain the flexibility of the joints and increase the strength and endurance of the knee joints. Among all kinds of sports, squatting or standing squat, half squat can provide trunk, lumbar, lower abdomen, thigh, thigh muscle strength, bone and joint training, which is helpful for overcoming the aforementioned bending of knees, bending over and hunchback. has great effect.

However, when performing squatting exercises, the knees are often bent to a certain extent by the weight of the body, and then the standing posture is restored. In order to avoid sports injuries, beginners or users with weak thigh muscles will hold the table or the table with their hands. Objects are used to assist in supporting the weight of the body, but the aforementioned traditional methods have not been able to truly assist the sportsman to perform squatting. The posture of squatting movement requires the total force of the thigh muscles, abdomen and trunk back muscles. In the process of going up and down, improper force application or incorrect posture will cause too much stress to be concentrated on the knees or thighs. It is easy to cause knee wear or thigh muscle strain, and even affect the ability to walk in the future, and suffer harm before benefiting;

In recent years, the industry has additionally developed a variety of fitness equipment with squatting functions, such as China Taiwan Patent Announcement No. 313866 and No. I260235, wherein No. 313866 discloses that the user stands on a pivot and is located on the support and the handle pivoted on the bracket can synchronously drive the seat cushion and the leg tube. In operation, since the leg tube will move with the handle, the user's whole body will also be driven to change the posture, which not only does not allow the user to The whole body is straight, and the force on the waist and legs is small, so the amount of training for the lower body is insufficient to meet the needs of squatting. As for No. I260235, the seat cushion and the leg tube are designed in one piece, and are pivoted on the main frame. It is mainly used for stretching exercises. As for the squatting exercise, the user stands on the rear end of the main frame. It is a bit similar to the traditional method of squatting by holding something, which cannot meet the user's squatting exercise needs.

In other words, the aforementioned equipment for assisting squatting cannot really assist the user in squatting, and it does not have the function of aggravating the training effect when squatting. For users who need to increase the amount of training, they cannot meet their needs.
