Description

Technical Field

[0001] The present invention relates to the technical field of sports protective gear, and in particular to a knee joint brace. Background Art

[0002] With the development of national fitness movement in my country, by 2020, the number of people who regularly participate in physical exercise has exceeded 400 million. Sports injuries are common injuries that occur in competitive sports, mass sports activities and daily life, with an incidence rate between 10% and 20%.

[0003] Common sports injuries include anterior cruciate ligament injury and meniscus injury, which seriously affect the labor capacity and quality of life of the people. In order to protect the knee joint, a protective cloth is usually wrapped around the knee joint. By setting Velcro at both ends of the protective cloth, the protective cloth can be tightly wrapped around the periphery of the knee joint to achieve protection. However, since sports injuries can cause instability of the knee joint, the knee joint will exceed the normal range of motion when the human body walks or exercises, causing excessive internal rotation or external rotation of the knee joint. The protective effect of conventional protective cloth is poor. Long-term improper use of the knee joint can induce serious secondary injuries such as osteoarthritis. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0027] The knee joint brace is described in detail below through specific embodiments:

[0028] Reference Figure 1 to Figure 2 As shown, some embodiments of the present invention provide a knee joint brace, comprising a brace body 1 and an elastic support member 2 arranged on the brace body 1 .

[0029] Among them, the brace body 1 is sequentially formed with a thigh fixing area 11, a knee fixing area 12 and a calf fixing area 13 along the vertical direction. The thigh fixing area 11 is used to be fixed on the thigh, the knee fixing area 12 is used to be fixed on the knee, and the calf fixing area 13 is used to be fixed on the calf. Elastic support members 2 are arranged on both sides of the knee fixing area 12. The elastic support members 2 on both sides extend from the thigh fixing area 11 to the calf fixing area 13, that is, the two ends of the elastic support member 2 can contact the thigh and the calf respectively, and the bottom of the elastic support member 2 is inclined toward the direction of the elastic support member 2 on the other side, that is, the elastic support member 2 located in the thigh fixing area 11 and the elastic support member 2 located in the calf fixing area 13 are staggered, so that the elastic support member 2 can generate a larger elastic force to restore the deformation after being deformed under the action of external force.

[0030] Specifically, the elastic support members 2 on both sides of the knee fixing area 12 are symmetrically arranged, so that when the brace body 1 is twisted in different directions by the same angle, the same elastic force is generated, so that the knee joint is evenly stressed, thereby being able to train the knee joint to perform stable internal rotation and external rotation.

[0031] In specific implementation, the twisted brace body 1 is set at the knee joint. Since the thigh angle is fixed and will not deflect, the elastic force of the elastic support member 2 to restore the deformation can be converted into resistance to prevent excessive internal or external rotation of the calf, which can effectively strengthen the rotation muscle strength, exercise neuromuscular control ability, and enhance subjective stability. At the same time, due to the elasticity of the elastic support member 2, the knee joint can have a certain range of motion, and actions such as knee flexion can be performed.

[0032] Of course, it should be noted that when installing the knee brace of the present invention, the calf is first twisted to a certain angle, and then the brace body 1 is worn on the knee joint. When the human body walks, the angle of the calf returns to normal. At this time, the elastic support member 2 can still be deformed to generate a larger elastic force to restore the deformation, so as to provide resistance to prevent excessive internal or external rotation of the calf, thereby enhancing the stability of the knee joint.

[0033] Of course, it should be noted that the elastic support member 2 can also be adjusted in its setting position on the brace body 1 according to actual needs, and the present disclosure does not limit this. As long as it can be deformed to generate a larger elastic force to restore the deformation to provide resistance to prevent excessive internal or external rotation of the calf, it can be used.

[0034] In a specific implementation, the elastic support member 2 includes a first elastic support segment 21, a second elastic support segment 22 and a third elastic support segment 23 which are connected in sequence. The first elastic support segment 21 is vertically extended from the side of the thigh fixing area 11 to the knee fixing area 12, that is, when the brace body 1 is worn at the knee joint, the end of the first elastic support segment 21 away from the second elastic support segment 22 contacts the thigh, so that the elastic support member 2 can use the thigh as a reference, thereby driving the calf to twist.

[0035] Furthermore, the second elastic support segment 22 is obliquely extended from the side of the knee fixing area 12 to the bottom of the knee fixing area 12. Compared with the distribution along the vertical direction, such a configuration can increase the deformation of the second elastic support segment 22 under the action of external force, thereby increasing the elastic force of the second elastic support segment 22 to restore the deformation, so as to provide a greater rotational resistance to the calf, which can effectively enhance the rotational muscle strength and exercise neuromuscular control ability.

[0036] The third elastic support section 23 is vertically extended from the bottom of the knee fixing area 12 in a direction away from the knee fixing area 12, that is, when the brace body 1 is worn at the knee joint, the end of the third elastic support section 23 away from the second elastic support section 22 contacts the calf, which can make the calf twist with the thigh as a reference under the elastic force of the elastic support member 2, thereby improving the movement stability of the knee joint.

[0037] Specifically, continue to refer to Figure 1As shown, the knee joint brace also includes an elastic reinforcement member 3, which can also be deformed under the action of external force to generate a larger elastic force for restoring the deformation. The elastic force on the elastic reinforcement member 3 is superimposed on the elastic force on the elastic support member 2, which can provide a greater rotational resistance to the calf to enhance the control ability of the neuromuscular system.

[0038] Reference Figure 1 As shown, there are two elastic reinforcement members 3, and the two elastic reinforcement members 3 are respectively arranged on the sides away from each other of the two elastic reinforcement members 3. It can be understood that the two elastic reinforcement members 3 are arranged on both sides of the knee fixing area 12, and when the brace body 1 is twisted in different directions by the same angle, the same elastic force can be generated, and the elastic force of the superimposed elastic support member 2 can make the knee joint be evenly stressed.

[0039] Furthermore, the elastic reinforcement member 3 includes a first elastic reinforcement section 31 and a second elastic reinforcement section 32 connected to each other. The first elastic reinforcement section 31 is vertically extended from the side of the thigh fixing area 11 to the knee fixing area 12, that is, when the brace body 1 is worn at the knee joint, the end of the first elastic reinforcement section 31 away from the second elastic reinforcement section 32 contacts the thigh, so that the elastic reinforcement member 3 can be based on the thigh, thereby driving the second elastic reinforcement section 32 to twist.

[0040] The second elastic reinforcement section 32 is arranged to extend obliquely from the side of the knee fixing area 12 to the bottom of the knee fixing area 12. It can be understood that the oblique arrangement of the second elastic reinforcement section 32 can increase the deformation of the second elastic reinforcement section 32 under the action of external force, thereby increasing the elastic force of the second elastic reinforcement section 32 to restore the deformation. Specifically, the elastic reinforcement member 3 and the elastic support member 2 extend in the same direction and are arranged close to each other.

[0041] It should be noted that only the third elastic support segment 23 is provided on the calf fixing area 13 of the brace body 1. Compared with the first elastic support segment 21 and the first elastic reinforcement segment 31 on the thigh fixing area 11, it can avoid occupying too much space on the calf fixing area 13, save space, and improve the wearing strength of the brace body 1.

[0042] In a specific implementation, the elastic support member 2 and the elastic reinforcement member 3 are both arranged on the side of the brace body 1 away from the knee joint to prevent the elastic support member 2 and the elastic reinforcement member 3 from scratching the skin. In a specific implementation, a mounting pocket is arranged on the side of the brace body 1 away from the knee joint, and the elastic support member 2 and the elastic reinforcement member 3 can be accommodated in the mounting pocket to facilitate the installation and replacement of the elastic support member 2 and the elastic reinforcement member 3.

[0043] Of course, the elastic support member 2 and the elastic reinforcement member 3 may also be installed in other ways, and the present disclosure does not limit this, as long as the elastic support member 2 and the elastic reinforcement member 3 can be fixed to the brace body 1 and can be twisted to apply elastic resistance to the calf.

[0044] In some embodiments, reference Figure 1 As shown, a plurality of extension strips 14 are arranged at intervals on both sides of the brace body 1, and a hook and loop fastener 141 is arranged at the end of the extension strip 14 away from the brace body 1. The brace body 1 is a sticky fabric structure, and the hook and loop fastener 141 can be sticked on the brace body 1. When wearing, the knee fixing area 12 is first covered at the knee position, and then the extension strip 14 is passed around the thigh, knee joint or calf, and is stuck to the brace body 1 on the other side through the hook and loop fastener 141 on the extension strip 14, so as to complete the wearing of the knee joint brace, which is simple to operate and easy to disassemble and replace.

[0045] In a specific implementation, a relief portion 15 is formed on one of the two sides of the brace body 1 at a position corresponding to the extension strip 14 on the other side. This arrangement enables the extension strip 14 on one side of the brace body 1 to pass over the relief portion 15 on the other side and be directly attached to the brace body 1, so as to improve the wrapping property of the brace body 1.

[0046] It should be noted that the knee brace of the present disclosure can also be directly provided with a Velcro 141 on the brace body 1, and the present disclosure does not limit this. As long as the brace body 1 can be wrapped around the thigh, knee joint or calf, the Velcro 141 can be directly attached to the outer surface of the brace body 1 to complete the wearing.

[0047] Reference Figure 1 As shown, the brace body 1 is provided with an escape opening 16, and the adhesive buckle 141 passes through the escape opening 16 and is pasted on the brace body 1. That is to say, by providing the escape opening 16 on the brace body 1, it is not necessary to form the escape portion 15 on the brace body 1, so that the adhesive buckle 141 on one side of the extension strip 14 can be pasted on the brace body 1 after passing through the escape opening 16, and at the same time, the adhesive buckle 141 on the corresponding side of the escape opening 16 can be directly pasted on the brace body 1 on the other side. Through the adhesive buckles 141 at both ends, the wrapping strength of the brace body 1 at the knee joint can be improved to prevent the knee joint brace from falling off.

[0048] Reference Figure 1 As shown, the brace body 1 may also be provided with an avoidance portion 15 and an avoidance opening 16 according to actual needs, and the present disclosure does not limit this, as long as the brace body 1 can be wrapped around the knee joint.

[0049] In some embodiments, an opening 17 is provided at the center of the knee fixing area 12 to expose the knee, so as to prevent the knee from abutting against the brace body 1 when bent, thereby causing inconvenience in movement. Specifically, an elastic rubber strip 4 is provided at the periphery of the opening 17, so that the wearing position of the knee is defined by the elastic rubber strip 4, so that the knee can be exposed through the opening 17, and the elastic rubber strip 4 can also provide a certain elastic force to protect the knee joint.

[0050] When implementing it, refer to Figure 2 As shown, the knee joint brace also includes an anti-slip structure, which is arranged on the side of the brace body 1 for fitting with the knee joint. Specifically, the anti-slip structure is an anti-slip strip 5 protruding from the surface of the brace body 1, and the anti-slip strip 5 can be a silicone strip. Furthermore, there are multiple anti-slip strips 5, which are respectively arranged on the thigh fixing area 11 and the calf fixing area 13 to prevent the brace body 1 from moving and dislocating.

[0051] It should be noted that the anti-slip strip 5 can also be set at other positions, and the number and extension direction thereof are not limited in the present disclosure, as long as it can be set on the side of the brace body 1 that fits the knee joint to prevent the brace body 1 from moving or dislocating. Of course, the anti-slip structure can also be in other structural forms, which are not limited in the present disclosure and can be specifically set according to actual conditions.

[0052] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0053] The above are only specific embodiments of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to these embodiments herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
