Description

Technical Field

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

[0002] The structure of the knee joint is like a precise spring. When going down stairs or on the downhill section of mountain climbing, the ligaments, tendons, etc. mainly absorb the body weight and buffer the ground reaction force. The combination of body weight and speed places a relatively large burden on the knee joint. Professionally designed knee brace support products enhance the support and overall stability of the knee through methods such as binding, pressurization, or support strips, assisting the knee joint to share excessive improper forces instantaneously.

[0003] Most of the current sports knee braces on the market are made of elastic materials, and elastic components are added at the knee position to achieve their buffering and massage functions. However, the support and buffering effects on the side of the knee are limited. For example, the publication number CN217565024U discloses a knee brace support strip, which includes a top fixing component and a bottom fixing component. Placement grooves are provided inside both the top fixing component and the bottom fixing component. Three second support members are equidistantly arranged inside the placement grooves, and two first support members are arranged between two adjacent second support members. This utility model generates a flexion and extension elastic force in the sagittal plane direction of the human body through the flat strip-shaped support strip, and blocks the external force in the coronal plane direction of the human body. However, after being tied to the flexible elastic band on the leg, the support strip is prone to displacement during the bending process of the leg, so that the fulcrum of the bending elastic force is not located around the knee, greatly reducing the protection effect on the knee. Summary of the Invention

[0004] Aiming at the defects in the prior art, the purpose of the present invention is to provide a knee brace support.

[0005] According to a knee brace support provided by the present invention, it includes a support plate and a support strip;

[0006] The support plate is in a plate structure, the support strip is a convex plate strip with elasticity, the support strip includes a protruding part and arm parts on both sides of the protruding part, two support plates are respectively connected to both sides of the protruding part, two arm parts are respectively pressed against the upper surfaces of the two support plates, the width of the support strip is smaller than the width of the support plate, and the support plates located on both sides of the protruding part are respectively denoted as the first support plate and the second support plate;

[0007] When the knee brace support is in use, the lower surface of the first support plate fits against the side of the thigh, the lower surface of the second support plate fits against the side of the calf, the protruding part is located on the side of the knee, the protruding direction of the protruding part is parallel to the coronal plane of the human body, the first support plate and the second support plate approach or move away from each other with the protruding part as the center, and the elastic acting force of the support strip acts on the leg through the support plate.

[0008] In some embodiments, a relief groove is provided in the protruding portion, and the relief groove is an open groove formed by extending a predetermined distance from the end face of the protruding portion towards the surface of the support bar.

[0009] In some embodiments, the support bar is made of rubber or plastic.

[0010] In some embodiments, the support plate and the support bar are integrally formed.

[0011] In some embodiments, the connecting end A where the first support plate is connected to the support bar is funnel-shaped, and / or the connecting end B where the second support plate is connected to the support bar is funnel-shaped.

[0012] In some embodiments, the length of the first support plate is greater than the length of the second support plate.

[0013] In some embodiments, a first relief hole is provided at the end of the first support plate, and / or a second relief hole is provided at the end of the second support plate.

[0014] In some embodiments, a rib is further included. The rib is an elastic strip, and the rib is embedded in the support bar in a manner parallel to the support bar. Both ends of the rib extend into the first support plate and the second support plate respectively, and the hardness of the rib is greater than the hardness of the support bar.

[0015] In some embodiments, the first support plate is provided with a first open groove, the second support plate is provided with a second open groove, and the protruding portion is provided with a relief groove. The first open groove, the relief groove, and the second open groove have the same opening direction and are arranged in a through manner. The rib is detachably connected to the cavity formed by the through arrangement of the first open groove, the relief groove, and the second open groove.

[0016] In some embodiments, a third open groove with an opening direction opposite to that of the relief groove is provided on the arm portion. Two groups of the third open grooves are respectively located between the first open groove and the relief groove and between the second open groove and the relief groove. The third open groove extends towards the direction of the relief groove and is communicated with the cavity accommodating the rib.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The knee support of the present invention is formed by connecting a flat support plate through a convex-shaped support strip. On the basis of maintaining a plate structure that can resist the external force of left and right swing from the coronal plane of the human body and the external force of rotation from the sagittal plane of the human body, not only is the conduction efficiency of the elastic force improved by increasing the contact area between the support plate and the leg, but also the knee support that is basically strip-shaped is deformed into a plate-strip structure. Since the cross-section of the protrusion part at the knee is relatively narrow, when the knee support bends and extends, it can basically bend and extend around the center of the protrusion part. Most of the elastic acting forces can use the protrusion part as a fulcrum to assist the lower leg or thigh in moving. And the protrusion part is located on the side of the knee. Therefore, the movement of the knee support can be consistent with the movement of the knee joint, improving the protection of the knee joint and solving the technical problem of poor protection effect caused by the difficulty in ensuring that the support point is located at the knee joint when the strip-shaped knee support with basically the same width bends and extends.

[0019] 2. The knee support of the present invention further optimizes the structural design of the support strip and the support plate to improve the protection effect of the knee support on the knee joint and enhance the comfort of the wearer.

[0020] 3. The knee support of the present invention designs the knee support as a sandwich structure. By using ribs with a hardness stronger than that of the support strip and embedded in the support strip, on the one hand, it can play a stronger and more comprehensive protective role on the knee joint. On the other hand, by using a detachable connection method to replace the cores of different materials, the flexibility of using the knee support and the experience of consumers are improved.

[0032] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0033] Example 1

[0034] This embodiment provides a knee brace, which mainly includes a support plate 1 and a support bar 2. Figures 1-10 The support plate 1 is a plate structure, which can be a structure with a certain elasticity formed by rubber or plastic material. In this embodiment, the support plate 1 is a rectangular structure plate. The support strip 2 is a convex strip with elasticity. The so-called strip refers to a long strip of plate structure, such as Figure 1 As shown, in this embodiment, the support bar 2 is an elastic structure formed of rubber or plastic material. The support bar 2 includes a protrusion 21 located in the middle and arms 22 located on both sides of the protrusion 21. The two L-shaped slots formed by the protrusion 21 and the arms 22 on the support bar 2, the ends of the two support plates 1 are snap-connected in the L-shaped slots, that is, the two support plates 1 are snap-connected to the left and right sides of the protrusion 21, and the two arms 22 located on both sides of the protrusion 21 are crimped on the upper surfaces of the two support plates 1. The lower surface of the protrusion 21 after connection is flush with the lower surface of the two support plates 1, and the width of the support bar 2 is smaller than the width of the support plate 1, so that the front and rear sides of the protrusion 21 form a clearance gap, and the clearance gap can make the two support plates 1 bend smoothly with the protrusion 21 as the center. In this embodiment, the support plate 1 and the support bar 2 are made of the same material and are an integrated structure formed by one-piece molding.

[0035] When the knee support formed by connecting in this way is in use, taking the case where the knee support fits on the outer side of the leg as an example, the lower surface of the first support plate 11 fits on the outer side of the thigh, the lower surface of the second support plate 12 fits on the outer side of the calf, and the protruding part 21 is located on the outer side of the knee. At this time, the protruding direction of the protruding part 21 of the support bar 2 is basically parallel to the coronal plane of the human body. The so-called coronal plane of the human body is a cross-section that longitudinally cuts the human body into front and rear parts along the left and right directions of the human body.

[0036] When the knee joint makes flexion and extension movements in the sagittal plane, the so-called sagittal plane is a cross-section perpendicular to the coronal plane and longitudinally cuts the human body into left and right parts. For example, during the squatting and standing up process, the first support plate 11 and the second support plate 12 approach or move away from each other along with the thigh and calf of the human body. The first support plate 11 and the second support plate 12 drive the support bar 2 to bend and stretch basically centered on the protruding part 21. The reaction force generated by the elastic deformation of the support bar 2 can buffer the too-fast bending movement of the leg, and at the same time can effectively assist the stretching movement of the leg, preventing damage to the knee joint caused by the too-fast bending of the leg or excessive pressure during the stretching movement, and playing a good role in protecting the knee joint. In this embodiment, a knee support is formed by connecting a convex-shaped support bar to a flat plate-shaped support plate. On the basis of maintaining the plate-shaped structure capable of resisting the external force of left and right swing from the coronal plane of the human body and the rotational external force of the human body's sagittal plane, not only the conduction efficiency of the elastic force is improved by increasing the contact area between the support plate and the leg, but also the knee support that is basically strip-shaped is deformed into a plate-strip structure. Because the cross-section of the protruding part at the knee is relatively narrow, when the knee support bends and stretches, it can basically bend and stretch centered on the protruding part, so that most of the elastic acting forces can use the protruding part as a fulcrum to assist the calf or thigh in moving. And the protruding part is located on the side of the knee, so the movement of the knee support can be consistent with the movement of the knee joint, improving the protection of the knee joint and solving the technical problem of poor protection effect caused by the difficulty in ensuring that the support point is located at the knee joint when the strip-shaped knee support with basically the same width bends and stretches.

[0037] Embodiment 2

[0038] This Embodiment 2 is formed on the basis of Embodiment 1. By further optimizing the structural design of the support bar and the support plate, the protection effect of the knee support on the knee joint is improved, and the comfort of personnel wearing is enhanced. Specifically:

[0039] Such as Figures 1-10As shown in the figure, a relief groove 211 is provided on the protruding portion 21 of the support bar 2. The relief groove 211 is an open groove formed by extending a predetermined distance from the end face of the protruding portion 21 towards the left side face (or right side face) of the support bar 2. When the support bar 2 bends with the flexion and extension movement of the knee joint, the cavity structure formed by the relief groove 211 enables the protruding portion 21 to bend more smoothly, preventing the protruding portion 21 from being difficult to bend when the bending angle is too large and avoiding situations such as extrusion damage when the bending angle is relatively large, improving the auxiliary support effect of the knee support on the knee joint and its own service life. Further, the connection end A111 where the first support plate 11 is connected to the support bar 2 is designed in a funnel shape, that is, the width of the connection end A111 at the connection with the side face of the protruding portion 21 is the same as the width of the protruding portion 21, and gradually widens towards the other end to be the same as the width of the trunk part, forming a funnel shape. The funnel-shaped connection end A111 can form a relief when the support bar 2 bends, avoiding collision between the first support plate 11 and the support bar 2 and affecting the bending of the support bar 2. Even further, the connection end B121 where the second support plate 12 is connected to the support bar 2 is also designed in a funnel shape, with the same structure as the connection end A111.

[0040] This embodiment also provides a structure of the support plate 1. A first relief hole 112 is formed at the end of the first support plate 11. The first relief hole 112 can overall reduce the weight of the knee support and improve the comfort when worn on the human leg. Similarly, a second relief hole 122 is formed at the end of the second support plate 12. The second relief hole 122 can further reduce the weight of the knee support.

[0041] Further, when the knee support is in use, the first support plate 11 is used as the structure located on the side of the thigh, and the second support plate 12 is used as the structure located on the side of the calf. The length of the first support plate 11 is greater than the length of the second support plate 12, which is more in line with human design ergonomics and improves the protection effect of the knee support on the knee joint.

[0042] Embodiment 3

[0043] This Embodiment 3 is formed on the basis of Embodiment 1 or Embodiment 2. The knee support is designed as a sandwich structure. By using ribs with a hardness stronger than that of the support bar and embedded in the support bar, on the one hand, it can play a stronger and more comprehensive protective role for the knee joint. On the other hand, by using a detachable connection method to replace the cores of different materials, the flexibility of using the knee support and the consumer experience are improved. Specifically:

[0044] As Figures 1-10As shown, a rib 3 is embedded in the support bar 2. The rib 3 is a strip plate with elastic function, for example, it can be a rectangular plate, or a runway-shaped plate with semicircular ends and a rectangular middle. The rib 3 and the support bar 2 are arranged in a parallel manner, and the two ends of the rib 3 extend to the first support plate 11 and the second support plate 12 respectively. The material of the rib 3 can be a strip formed by injection molding of rubber or plastic, and the hardness of the rib 3 is greater than the hardness of the support bar 2. By embedding the rib 3 with greater hardness in the support bar 2, not only the rib 3 and the support bar 2 form a composite elastic force, thereby improving the auxiliary effect of the knee brace support on the flexion and extension of the knee joint, but also the rib 3 and the support bar 2 with higher hardness have a stronger offset and buffering effect on the external forces in the coronal plane and the horizontal plane, which can better protect the knee joint. Moreover, when the knee joint is subjected to external force from the coronal plane of the human body, due to the greater hardness of the rib 3, it can produce a greater resistance to the external force perpendicular to the side of the knee after being combined with the support bar 2, thereby effectively offsetting and buffering the external force of the knee joint on the coronal plane, and providing more effective protection for the knee joint. Similarly, when the knee joint is subjected to external force of rotation in the horizontal plane, the knee joint can also be better protected by the improvement of the rib 3. The so-called horizontal plane refers to the cross section that cuts the human body into upper and lower parts.

[0045] Furthermore, a first opening groove 113 is provided on the first support plate 11, and a second opening groove 123 is provided on the second support plate 12. The opening directions of the first opening groove 113, the second opening groove 123 and the clearance groove 211 are the same. At this time, the protrusion 21 is still provided with the clearance groove 211, and the first opening groove 113, the clearance groove 211 and the second opening groove 123 are sequentially arranged through. The distance between the first opening groove 113 and the second opening groove 123 is substantially the same as the length of the rib 3. One end of the rib 3 enters the clearance groove 211 from the first opening groove 113 and then enters the second opening groove 123. After the rib 3 is in place, the other end of the rib 3 is located in the first opening groove 113. Through this structural form, the embedded connection of the rib 3 can be changed into a detachable mode, and the ribs 3 of different materials can be replaced according to the protection level requirements of the knee pad support, so as to timely change the parameters such as the elastic force and hardness value of the knee pad support, which is flexible and convenient, and can effectively reduce the cost.

[0046] Further, a third opening groove 221 is respectively provided on the arm portions 22 on both sides of the protrusion 21. The two third opening grooves 221 are respectively located between the first opening groove 113 and the relief groove 211 and between the second opening groove (123) and the relief groove 211. The opening direction of the third opening groove 221 is opposite to the opening direction of the relief groove 211, and the two sets of third opening grooves 221 are communicated with the cavity structure of the accommodating rib 3. By providing the third opening groove 221, the cavity wall surface of the accommodating rib 3 can be reduced, thereby improving the disassembly and assembly efficiency and convenience of the rib 3 in the support strip 2. At the same time, the overall weight of the knee support can be further reduced, making it lighter and improving the comfort of consumers when wearing and using it.
