Detailed ways

The bottom panel of a bed board 1 is fixed with 5-8 rolling bearings. The rolling bearing is the prior art: it consists of an outer ring, steel balls and an inner ring. The outer ring of the rolling bearing is fixed on the lower surface of the bed board 1, and a bed board rotating shaft 3 passes through all the rolling bearings. and then the two ends of the bed board rotating shaft 3 are fixed on the support frame 7, the bottom of the support frame 7 is fixed on the ground, the length of the bed board 1 is 2 meters, the bed board rotating shaft 3 is located at the center of the bed board 1 length direction, and the The top is 30-40cm from the ground.

There are two circles 2 on both sides of the upper surface of the bed board 1. The plane of the circle 2 forms an angle of 135 degrees with the plane of the bed board 1. The distance between the two circles 2 on the same side is 30-50 cm. All the circles 2 are connected to the nearest bedside. The distances between the baffle plates 5 are all equal, that is to say, the positions of the four circles are symmetrical about the median line in the length direction of the bed board 1 . The human body is lying on the bed, and the fixed rope 8 passes through four circles 2, and then the body is fixed by knotting to reduce the sliding of the body.

The inner surface of the headboard 5 is fixed with elastic materials, such as pillows, elastic pads, etc., to weaken the impact of the head and the headboard 5 that can occur.

One end of the upper surface of the bed board 1 has a calf resting frame 10, and a pillow 4 is arranged at the other end. The height of the pillow is 3-5cm, the width is 20-30cm, and the length is 30-50cm. The width direction of the pillow is the length direction of the bed, and the length direction of the pillow is the width direction of the bed board. The intensity of impact with the bed board 1. For guaranteeing the comfort of body, the upper surface of bed board 1 is fixed the thick cotton pad of one deck 1cm. Handrails 9 are arranged on both sides of the bed board 1 near the pillow 4, and the distance between the handrails and the nearest bedside baffle 5 is 50-60cm.

The two ends of bed board 1 length direction, the lower panel of bed board 1, respectively fix an end of a spring 6, and the other end of spring is fixed on the ground. When the bed board 1 swings, the springs at both ends play a role in hindering the movement, that is, a buffering effect, which slows down the moving speed and reduces bumps.

The distance between calf rest frame 10 and the nearest headboard baffle 5 is 50-60cm, and there is a central groove flush with bed board 1 in the middle of the calf rest frame, and there are gradually raised grooves on both sides of the central groove, gradually The raised groove has two levels, and the height difference between each level is 20cm, that is, the vertical drop between the first level and the central groove is 20cm, and the vertical difference between the second level and the central groove is 40cm.

The method of use is to lie flat on the cotton pad on the upper surface of the bed board 1, move the body back and forth, so that the body and the bed board system are in a state of balance, that is, without any external force on the bed board, the bed board can maintain a horizontal state, and then the body moves slightly to promote The bed board is tilted, the head is at the top and the feet are at the bottom. Under the action of the spring force (the spring under the head is stretched, there is a downward pulling force, and the spring under the feet is compressed, and there is an upward supporting force. The two forces are opposite to each other. The direction of moment of the bed board rotating shaft 3 is the same, they work together to overcome the moment generated by the movement of the center of gravity of the body), the inclination angle between the bed board and the horizontal plane is kept at 0-5 degrees is the best, at this time, a fixed rope 8 passes through four circles 2. Bind the body slightly to reduce the sliding of the body; place a pillow 4 under the head, hold the armrest 9 with your hands, and gradually move the left and right calves to a certain level of groove on the calf shelf 10, raise the calves upwards, and straighten the thighs at the same time , which causes the center of gravity of the legs to move backwards, so that the center of gravity of the whole body gradually moves to the head side, causing the head to gradually drop below the horizontal plane. Counting the central groove, the groove has three levels, and the two legs can be at different positions. Grooves that create nine CG positions, with both feet raised into the outermost grooves where the CG moves the most. Normally, the body is in two states of standing upright and lying down most of the time. The vascular system of the human body is more adapted to this state, and the human body will basically not be in an inverted state. When the human body occasionally stands upside down, due to gravity, the water will flow down and the brain The blood volume of the blood vessels will increase, and the normal blood circulation is not suitable for this state. The return flow of blood is blocked, the blood pressure will rise, and even hypoxia in the head will occur, which will cause very discomfort and even accidents. The device is slightly tilted, causing the head to stand upside down to a certain extent. The maximum inversion angle of the device is about 23.5 degrees (sin23.5=40cm/(1 meter), where 1 meter is half the length of the bed board and 40 cm is the bed board The top of the rotating shaft 3 is 30-40cm away from the ground, and the angle of inversion can also be reduced by placing a support on the ground on one side of the head; in addition, it is also related to the strength of the spring. Small), the adaptability of the handstand is controlled by the operator's legs, if he feels uncomfortable, push to the lower groove to reduce the angle of inclination.
