Description

Lean on riser subassembly among quiet auxiliary device of squatting of wall

Technical Field

The invention belongs to the field of fitness equipment, and particularly relates to a vertical plate assembly in a wall-leaning squatting assisting device.

Background

Crouching by leaning on the wall is an exercise method which is very suitable for ordinary people, can be carried out at home by leaning on the wall, and has low cost and convenience. The sitting on the wall is mainly used for exercising the muscle strength of quadriceps femoris, and is particularly suitable for exercising few people who want to strengthen the muscle strength of thighs, people in early and middle recovery period after joint injury, and the like, such as vast office workers.

When carrying out the quiet exercise of squatting that leans on the wall, people's back leans on the wall, and both feet part to with the shoulder width, then both feet are stretched forward gradually, and form the certain distance between the health focus, and the health presents the posture of squatting, makes shank major axis and ground perpendicular, insists on for a period, reaches the purpose of tempering. When in exercise, the included angle between the thigh and the shank is not less than 90 degrees, each time of sitting on the wall is kept as hard as possible until exhaustion, generally 1-2 minutes, then the user has a rest for 1-2 minutes, and the exercise is repeated for a plurality of times, so that the exercise effect is best.

Generally, when a person leans on a wall to squat and exercise statically at home, some accidents easily occur, for example, the friction force between the sole and the floor is small, so that the shoes and the ground slip easily, the feet of the person move unexpectedly, and the accidents easily occur during exercise.

In addition, when crouching statically against a wall, the buttocks of a person are in a suspended state and lack of support, so that support points are lacked in the process of standing up after preparation for the quiet crouching and the quiet crouching, the standing-up is inconvenient, and the situation that the body is unstable and falls down is easy to happen.

Therefore, to the still defect that exists above, this application provides a body-building auxiliary device for leaning on wall quiet exercise of squatting, has specifically studied the riser subassembly wherein.
