Problems solved by technology

The muscles of human legs will be stretched to different degrees during exercise. A single fabric elastic protection not only cannot provide reliable protection, but also greatly reduces the comfort during exercise.
[0008] In addition, in the existing protective gear, sweat is easy to accumulate, resulting in a decrease in comfort

no. 1 example

[0082] refer to Image 6 , is a schematic structural view of the first embodiment of the dynamic biofunctional leg brace of the present invention.

[0083] In the first embodiment, the structure and position of each protective band can refer to the above-mentioned figure 2 The introduction will not be repeated here. In this embodiment, the patellar tendon protective band A-2 specifically includes a left and right protective band starting from the lower edge of the patella, and both protective bands extend upward along both sides of the cruciate ligament protective band A-1 to strengthen the pressure on the patellar tendon.

[0084] Knitted materials with different elastic modulus under different deformation conditions are prepared by using the existing invention technology and used in the leg protector of this design. The material properties of each area are specifically shown in Table 1 below. In this embodiment, individual The materials corresponding to the regions are st...

[0090] refer to Figure 7 , the second embodiment and the first embodiment can be different strapping methods of the same leg protector. 3 On the basis of the first embodiment, one is added repeatedly to strengthen the pressure of the protective belt, thereby strengthening the fastening force and supporting force of this part. In addition, the patellar tendon protection band A-2 specifically includes two protection bands on the left and right starting from the lower edge of the patella, and the four protection bands extend upward along both sides of the cruciate ligament protection band A-1 to strengthen the pressure on the patellar tendon.

[0092] refer to Figure 8 , in this embodiment, the combination of the fabric with dynamic unidirectional water-conducting function in the thermal comfort zone B and the composite material with glue is used to realize the function of strengthening the resilience. The method of pressing glue is used on each protective belt to strengthen the pressure of the protective belt, thereby strengthening the fastening force and supporting force of this part. For the patellar tendon protective belt A-2, it includes three protective belts starting from the lower edge of the patella on the left and right, and six protective belts starting from the lower edge of the patella. The protective belts extend upward along both sides of the cruciate ligament protective belt A-1 to strengthen the patella. Tendon stress.

[0093] The material characteristics of the adhesive are that the unit weight is 250g / m2, the thickness is less than 1.1mm, the air resistance is 0.03kPa.s / m, the heat insulation is...

Abstract

The invention discloses a dynamic biological-function leg protective tool. The dynamic biological-function leg protective tool comprises a biomechanics protective belt arranged based on the structure positions and the directions of tendon ligaments and muscles of the knee and the biomechanics characteristics in the human-body exercise process. The biomechanics protective belt comprises a cruciate ligament protective belt, a patellar tendon protective belt, a thigh muscle group protective belt and a shank muscle group protective belt; periodical changes of the elasticity modulus of the cruciate ligament protective belt and the elasticity modulus of the patellar tendon protective belt are generated based on the fabric stretching ratio caused by knee bending, and the change stages include the initial stretching low-modulus stage, the stretching suddenly-changing stage and the stretching high-modulus stage which are gradually transited along with the reduction of the knee angle. According to the dynamic biological-function leg protective tool, comfortable elastic protection is provided for the knee bending action of a sportsman, the elasticity modulus of a knee material is correspondingly and automatically adjusted according to different knee angles caused by different exercise knee bending ranges, healthy and comfortable elastic protection can be provided under the small knee angle and the high exercise amount, perspiring can be achieved through heat comfortable areas, and the protective tool can be prevented from sliding through the strengthened anti-sliding belt.

Description

technical field [0001] The invention relates to the field of sports safety protectors, in particular to a dynamic biofunctional leg protector that provides protection, comfort and health of legs and knee joints in a sports state. Background technique [0002] The full leg protector, including the calf, knee joint and thigh, is used by athletes to protect the knee joint and leg muscle groups during exercise to avoid sports injuries. The full leg protector is generally divided into the following parts: elastic sleeve, support member, upper and lower edge members, etc. [0003] refer to figure 1 , The knee joint is composed of the medial and lateral condyles of the femur, the medial and lateral condyles of the tibia, and the patella. It is the largest joint in the human body with the most complex structure and more chances of injury. The stability of the knee joint mainly depends on ligaments and muscles, and the medial and lateral collateral ligaments and cruciate ligaments ...
