The ankle protector is connected to each other by using a connection frame (Fig. 9.600) that is capable of adjusting the height of the multi-step according to the calf length of the patient so that the weight applied to the knee of the patient from the upper support 110 of the knee protector to the sole plate of the ankle protector And an ankle protector and a detachable knee protector that protects the knee joint of the patient by dispersing to 350.

In general, the knee protector is an assistive device for stabilizing the rotational movement of the knee joint of cartilage injury patients due to degenerative arthritis or movement of the cartilage of the knee joint and reduces the pressure caused by the weight of the patient on the damaged knee joint. When the lower support belt is walking, the patient's thighs and calves are repeatedly removed and tightened, loosening and loosening the blood circulation well, and according to the patient's symptoms, he wants a knee protector that can adjust the rotation angle of the knee and ankle. .

As shown in the configuration of the invention of the 'knee knee joint device' Patent No. 10-0648639 of Figure 14

'That is, as shown in the use state of Figs. 3a and 3b and the operating state of Figs. 4a to 4d, the gap between the femur and cartilage of the knee joint is maintained in a normal state when the wearer's knee is bent. When the wearer stands up or stands up in a chair, the second towing member 130 is gradually lowered by the rotational movement of the first towing member 110 so that the interval between the femur and the cartilage of the knee joint is gradually spaced apart. Will be done. '

However, such a method requires a lot of accessories such as a fixing piece 155 to fix one end of the spring 153, the connecting member 150, a locking piece 131, and the first towing member 110 and the second. Since the traction member 103 is not completely mechanically connected to each other, the operation is unstable and the rotatable angle cannot be adjusted, and the knee rotation angle used by the patient when walking is separated by a small amount between 10 and 40 degrees, so the effect of traction is small.

In addition, as shown in the configuration and operation of the design of the registration device No. 20-0378573 'Knee protection and impact relief device installed on the knee protector' of Figure 15,

'The present invention is a knee protector formed on the side of the knee protector,

'

However, this method requires a complex structure and many accessories such as the tubular body 30 and the spring 20, and the rotation angle cannot be adjusted, and the patient is completely towed by the upper support and the lower support only when the knee is fully bent. When the knee is slightly bent at 10 to 40 degrees to walk, the tightening belt is less likely to be pulled out and pulled from the patient's thigh.

As also shown in US 2006/0135904 A1 of FIG. 18,

One rubber band 18 surrounds the knee at the upper support 40 and connects it to the lower support 42, and the other rubber band 20 wraps the knee at the lower support 42 and the upper support 40. By connecting the O-type legs to X-type legs to induce deformation.

However, the present invention attaches the center of the rubber band to the knee rotation center axis (Fig. 4.400), one side wraps the thigh and connects to the upper support 110, the other wraps the calf and connects to the lower support 120 Induce the deformation of the O) leg into the X (XO type leg) and at the same time pull the shaft center of the knee rotation backwards by using the elasticity of the rubber band to help the knee frame's rotation frame and the fixed frame stand upright.
