Electric Control Sit Up Massage Chair

Technical field:

The invention relates to the technical field of fitness equipment, in particular to an electrically controlled sit-up massage chair.

Background technique:

With the development of science and technology and the progress of society, people's competition is becoming more and more fierce, so people's working hours, especially the sitting and lying time of office workers are relatively longer and longer, which has caused people's common diseases , frequently-occurring diseases such as cervical spondylosis, waist and leg pain are increasing, the reason is that one is less exercise time, and the other is the lack of health massage. Get better, such as walking machine, stepper, pedal exercise bike, tension device, gravity training device, horse riding fitness device, etc., No. 92209350.4 patent, No. It is simple, and the price is also reduced, but the motivation of its exercise is to complete by exercising one's own strength. For most people, they can do a few times at the beginning, but after a long time, they lose patience and enthusiasm. Just like fitness equipment such as steppers and tension machines, they are covered with dust indoors and are no longer cared about. They are just like decorations. There are also health massage equipment, but they are limited to leg massage.

Invention content:

The purpose of this invention is to provide a new type of sports equipment with beautiful appearance and scientific structure, so that it can achieve the effect of sit-ups or leg exercises without using the strength of the human body, and can automatically control the head, The purpose of random massage on the neck, back, waist, buttocks and legs is to make sports and health care no longer a burden, but a kind of enjoyment.

The present invention is achieved in the following way: the electric control sit-up massage chair is composed of a base, a motor, a connecting rod, and a massage wheel, wherein a cushion is arranged on the upper part of the base, a backrest is arranged on one side of the cushion, and a backrest is arranged on the backrest. There are more than three massage wheel shafts, each of which is provided with more than two freely rotatable massage wheels, and an electric motor is arranged at the lower part of the seat cushion. The rotating shaft of the backrest swings within a limited angle, and armrests are movably connected to the left and right sides of the seat cushion and the backrest, and a control device capable of controlling the swinging speed and angle of the backrest is arranged on the armrests.

The above-mentioned swing speed control of the backrest is realized by changing the rotational speed of the motor, and the swing angle control of the backrest is controlled by an infrared sensor on the backrest angle adjustment point and the starting point near the worm shaft or the backrest rotation axis The steering of the motor is realized, the armrest can be adjusted to float up and down with the swing of the backrest through the adjustment of the connecting rod, and the base can be moved flexibly through the rollers arranged below it.

The upper part of the backrest is connected with a rotating shaft to swing with the revolution of the backrest, and also to rotate and swing through the small backrest connecting rod connected to the base, the rocker arm on the backrest and the large backrest connecting rod. There are more than two massage wheel shafts set on the top, and more than two free-rotating massage wheels are arranged on the shaft. On the other side of the seat cushion, there is a massage wheel that is driven by the rocker arm on the worm shaft and the swinging link of the legs to do the opposite direction to the backrest. The swinging legs swing the board in the same direction.

The upper part of the above-mentioned two-leg swinging plate is provided with a leg support rod, and the lower part is provided with a foot hook rod. On both sides of the massage wheel on the large rocker arm, there are freely rotatable massage sticks that can prevent the human body from tilting to both sides. .

The other side of the cushion is not provided with two legs swinging in the same direction, but the upper part below the other side of the cushion is provided with a leg strut connected to the base, and the bottom is provided with a foot hook link connected with the base.

The length and rotation angle of the above-mentioned leg support rod are adjusted by the leg support rod adjustment device, the length and rotation angle of the foot hook rod are adjusted by the foot hook rod adjustment device, and a shoe-sole shape is arranged on the corresponding position on the base below the foot hook rod. footrest.

Remove the swing plate and the connecting rods of the legs connected to it, set the backrest and the big rocker arm as two parts that can respectively drive the left and right legs to swing crosswise, and drive the rocker arms on both sides of the worm shaft at the same time to the connecting rod on the backrest The angles of the connection points on the seat are connected with a difference of 180 degrees. On the other side of the seat cushion, there is a backrest that can adjust the inclination angle through an adjustment device and an armrest that is linked with it.

The outstanding advantages of the present invention compared with prior art are:

1. The present invention integrates sit-up exercise and health care massage. The person who needs to be massaged sits on the electric-controlled sit-up massage chair and does not need to apply force to relax his muscles. The power of the motor drives him to perform sit-ups. At the same time, health massage is performed on the neck, back, waist or legs of the massaged person, so that exercise and health care are no longer a burden, but a kind of enjoyment.

2. The present invention has a better health care effect especially for patients with cervical spondylosis and waist and leg pain.

3. The present invention is only a backrest or a leg exercise device, which is suitable for use in offices.

4. The present invention is suitable for all ages, occupies a small space, has a simple structure, low cost and obvious effect.
