Description

Technical Field

[0001] The present invention relates to the technical field of sports protection, specifically to a silicone rubber gasket, and more particularly to a silicone rubber gasket and knee pad device that adapts to the patellar shape through optimized structural design, provides differentiated pressure areas, and has a massage function. Background Art

[0002] As one of the important joints in the human body, the knee has a very complex structure of bones, cartilage and ligaments. During daily exercise or sports activities, the knee is easily hit and bumped, and these external forces may cause varying degrees of damage. In order to protect the knees from injury, sports protective gear usually contains anti-collision gaskets or fillers specially designed for the knee structure. When designing knee pads, designers will build a silicone gasket into the center of the knee, at the position of the patella, in order to apply appropriate compression force to the patella, ensure its stable position, and provide anti-collision and cushioning effects. These gaskets are generally made of tpr rubber or silicone, with a common ring shape and raised particles designed on the surface. For example, Figure 1 The one shown is a pure oval silicone gasket. Figure 2 The one shown is a silicone pad with an array of convex teeth and two large protruding massage bumps. Figure 3 It is a kind of protective pad, and its surface is also designed with convex teeth and large protruding massage pads.

[0003] However, the silicone rubber pads mentioned above have some shortcomings. They usually only surround the high point of the patella and rely on the elasticity of the knitted fabric of the knee brace itself to fix the position of the pad on the patella. Therefore, it can be expected that:

[0004] 1. Because the human patella is not a standard oval shape (see Figure 4 ), the silicone rubber pad does not support and wrap the patella very tightly, which may cause the patella to vibrate, shake or even become unstable during exercise;

[0005] 2. Since silicone rubber pads rely on the elastic pressure of knitted fabrics to fix them, common silicone rubber pads are almost all solid, which makes them relatively large in size and weight, resulting in higher material costs.

[0006] 3. Since the silicone rubber pad is solid, it must be filled with material when transitioning between high and low surfaces. This results in an almost slow transition or uniform pressure distribution on the entire pad, which may not provide the best support and protection effect and is difficult to meet ergonomic requirements. Summary of the Invention

[0007] The purpose of this invention is to develop a differentiated massage silicone rubber gasket and knee brace that fits the patella, ensuring a close fit and achieving differentiated pressure distribution based on ergonomic principles. The gasket also provides acupressure massage, applying gentle, gradual pressure to specific acupoints to relieve pain and promote blood circulation. Furthermore, the gasket aims to reduce overall weight and production costs, making it not only comfortable and effective, but also affordable and readily available.

[0008] To achieve the above-mentioned objectives, the present invention first provides a differentiated massage silicone rubber gasket adapted to the patella, the key of which is that it includes a gasket body, an arc-shaped transition structure arranged on the inner edge of the gasket body, and a differentiated massage structure arranged on the knee contact surface on the inner side of the gasket body; the arc-shaped transition structure is used to adapt to the shape of the human patella; the differentiated massage structure is used to form a soothing transition pressure value adaptation area around the Heding point, the Nei Xiyan point and the Dubi point on the one hand, and on the other hand, it is used to achieve weight reduction through its hollow part that is not completely filled according to the knee contact surface.

[0009] Furthermore, a convex support structure is provided on the outer support surface of the gasket body, which is not only used to cooperate with the differentiated massage structure to form pressure mapping, but also achieves further weight reduction through its hollow part that is not completely filled according to the support surface.

[0010] Furthermore, the inner edge of the gasket body is set to a non-standard elliptical shape corresponding to the shape of the human patella, and the arc-shaped transition structure includes a circle of closed inner arc surface formed around the circumference of the inner edge, and the closed inner arc surface tends to expand along the support surface of the gasket body to its knee contact surface.

[0011] Furthermore, the differentiated massage structure includes main massage protrusions arranged in one-to-one correspondence with the Heding point, Nei Xiyan point and Dubi point.

[0012] Furthermore, a plurality of gradual massage protrusions with a sinking trend and gradually decreasing surface areas are arranged around each main massage protrusion.

[0013] Furthermore, the convex point support structure includes a plurality of pressure mapping convex points provided on the support surface of the gasket body.

[0014] Furthermore, the pressure mapping convex points are evenly distributed on the supporting surface of the gasket body, and their shapes and protruding heights are consistent.

[0015] Furthermore, three groups of reinforcing ribs are used to divide the outer edge and inner edge of the gasket body into three massage areas corresponding to the Heding point, the Nei Xiyan point and the Dubi point, and the two groups of reinforcing ribs can limit the displacement of the patella.

[0016] Furthermore, the gasket body, the arc-shaped transition structure, the differentiated massage structure, the convex support structure and the reinforcing ribs are integrally formed, and are all made of silicone rubber material with a hardness of 0 to 40 degrees.

[0017] Based on the above description, the present invention further discloses a knee support device, the key of which is that it includes the above-mentioned differentiated massage silicone rubber gasket adapted to the patella.

[0018] Compared with the prior art, the present invention has the following remarkable effects:

[0019] (1) The present invention adopts a non-standard oval-shaped washer body inner edge design, combined with an arc-shaped transition structure, so that the silicone rubber washer can more closely fit the actual shape of the human patella. This design effectively reduces vibration and shaking during exercise, thereby improving the stability and comfort of the knee brace;

[0020] (2) By designing a differentiated massage structure, the present invention provides a soothing transition of massage pressure around key acupuncture points such as the Heding point, the Neixiyan point, and the Dubi point. At the same time, the hollowed-out portion of the knee contact surface is not fully filled to achieve weight reduction and reduce material costs. In addition, the combination of the main massage protrusion and the gradient massage protrusion can provide a more personalized and individual massage effect according to the selection of silicone rubber materials of different hardness;

[0021] (3) The main massage protrusions precisely correspond to the Heding point (the midpoint of the upper edge of the patella), the Nei Xiyan point (the inner depression of the patellar ligament) and the Dubi point (the outer depression of the patellar ligament) around the patella. These key acupoints / pain points combine the targeted treatment of Chinese medicine acupoints with sports protective gear, which helps to relieve knee weakness, reduce inner pain and improve outer strain. The gradient massage protrusions are centered on the main massage protrusion and are distributed in a surrounding gradient. The surface area contacting the skin decreases step by step, forming a soothing transition of pressure to achieve a better massage effect. The gradient protrusion group can also form a "micro-anchor array" to increase the friction between the gasket and the skin and prevent dynamic instability of the patella;

[0022] (4) The synergistic effect of the convex support structure and the differentiated massage structure forms a pressure map, which accurately matches the convex layout of the knee contact surface with the convex layout of the support surface, forming an adjustable pressure transmission path. In this way, the pressure type and intensity of different areas can act on the patella and surrounding tissues as needed. By adjusting the density, size, distribution surface area, shape, etc. of the supporting convex points, different support feelings for the skin can be achieved. At the same time, the mutual cooperation between the knee contact surface and the support surface can achieve different massage effects;

[0023] (5) The reinforcing ribs not only enhance the structural strength of the gasket body, preventing it from deforming during use, but also strengthen the support of the patellar tendon and the left and right sides of the patella. In addition, considering the principles of ergonomics, the reinforcing ribs can also play a role similar to the patellar strap, limiting the displacement of the patella and allowing the knee joint to move within a safer range of motion, thereby reducing the risk of injury;

[0024] (6) The silicone rubber gasket is manufactured using an integrated molding process, ensuring uniform quality of each part of the gasket. The silicone rubber material used for the gasket maintains good elasticity and hardness within a hardness range of 0 to 40 degrees. This material selection not only ensures the durability of the product, enabling it to withstand long-term use without damage, but also ensures comfort during use, providing users with a more pleasant experience.

DETAILED DESCRIPTION

[0037] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0038] In the description of the present invention, it should be understood that the terms "length," "width," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0039] Figure 5 The first embodiment of the present invention is shown: a differentiated massage silicone rubber gasket adapted for the patella. The gasket comprises a gasket body 1, an arcuate transition structure 2 located on the inner edge of the gasket body 1, and a differentiated massage structure 3 located on the inner knee contact surface of the gasket body 1. The arcuate transition structure 2 is designed to adapt to the human patellar morphology. The differentiated massage structure 3, on the one hand, forms a soothing transition between pressure zones around the Heding, Neixiyan, and Dubi acupoints, and on the other hand, reduces weight through hollowed-out portions that do not completely fill the knee contact surface. The main body of the silicone rubber gasket is designed as a closed annular structure of a specific thickness. Three protruding portions are designed at the edge, covering the Heding, Neixiyan, and Dubi acupoints, respectively. These protruding portions are integrally formed with the gasket body 1, forming a continuous, smooth curved surface. Each protruding portion cleverly corresponds to a key acupoint, ensuring precise massage. The streamlined design also reduces resistance during exercise, thereby enhancing wearer comfort.

[0040] See also Figure 6In this embodiment, a raised point support structure 4 is provided on the outer support surface of the gasket body 1. The raised point support structure 4 is not only used to cooperate with the differentiated massage structure 3 to form pressure mapping, but also achieves further weight reduction through its hollowed-out parts that are not completely filled according to the support surface. When the wearer is moving, the raised point support structure 4 interacts with the differentiated massage structure 3 to achieve a dynamic massage effect on the patella and surrounding tissues by changing the contact area and pressure distribution. At the same time, the design of the hollowed-out part not only reduces the weight of the entire gasket, but also enhances its breathability and perspiration-wicking properties, allowing the wearer to remain comfortable and dry when worn for long periods of time. This comprehensive design not only improves the practicality and comfort of the knee pad, but also provides users with a more personalized and precise massage experience.

[0041] like Figure 7 As shown, in a specific implementation, the inner edge of the gasket body 1 is set to a non-standard elliptical shape corresponding to the shape of the human patella, and the arc-shaped transition structure 2 includes a circle of closed inner arc surface 201 formed around the circumference of the inner edge, and the closed inner arc surface 201 has an expansion trend along the support surface of the gasket body 1 to its knee contact surface. This design enables the gasket body 1 to better fit the natural curve of the human patella, ensuring the accuracy and effectiveness of the massage. The expansion trend of the closed inner arc surface 201 not only enhances the contact area between the gasket body 1 and the patella, but also helps to disperse the pressure on the edge of the patella during exercise, reducing the risk of patellar wear and pain, thereby improving the overall protective performance of the silicone rubber gasket. This non-standard elliptical inner edge design, combined with its unique arc-shaped transition structure 2, provides users with a more fitting, comfortable and efficient massage experience.

[0042] from Figure 7 and Figure 8 It can be seen that in actual application, the differentiated massage structure 3 includes main massage protrusions 301 corresponding to the Heding point, Neixiyan point and Dubi point, and a number of gradient massage protrusions 302 with a sinking trend and gradually decreasing surface area are arranged around each main massage protrusion 301. These main massage protrusions 301 adopt an ergonomically designed height and shape, which can accurately act on the Heding point, Neixiyan point and Dubi point, promote local blood circulation, and relieve muscle tension and pain. The gradient massage protrusions 302 surrounding each main massage protrusion 301, with their sinking trend and gradually decreasing surface area design, not only increase the layered sense of massage, but also gradually penetrate into the skin texture during the massage process, achieving a deep relaxation effect. The design of this differentiated massage structure 3 allows the silicone rubber gasket to provide a personalized massage experience while also ensuring the comprehensiveness and depth of the massage, further improving the user's comfort and satisfaction.

[0043] See also Figure 9 and Figure 10Specifically, the convex support structure 4 includes a number of pressure mapping convex points 401 provided on the support surface of the gasket body 1. These pressure mapping convex points 401 are carefully arranged to form a precise correspondence with the main massage protrusions 301 and the gradient massage protrusions 302 in the differentiated massage structure 3. When the wearer moves, the pressure mapping convex points 401 can dynamically adjust the support strength for the patella and surrounding tissues to achieve precise transmission and distribution of pressure. This design not only enhances the massage effect of the gasket, but also improves the stability and comfort of wearing. At the same time, the presence of the pressure mapping convex points 401 further enriches the massage level of the gasket, allowing the wearer to enjoy a more delicate and comprehensive massage experience. Taking area A of the knee contact surface as an example, assuming that this area is smooth, without the main massage protrusion 301 and the gradient massage protrusion 302, and on the support surface directly opposite it, there is a larger and higher pressure mapping protrusion 401 corresponding to the back of area A, then the skin will feel a uniform and relatively comfortable surface massage area; however, if area A of the knee contact cover surface is a larger and higher main massage protrusion 301, and there is also a larger and higher pressure mapping protrusion 401 on the corresponding support surface, then the skin will feel a massage point with very strong pressure.

[0044] In this embodiment, the pressure mapping protrusions 401 are evenly distributed on the support surface of the gasket body 1, and their shapes and protrusion heights are consistent. In some other embodiments, the shape, protrusion height and distribution density of the pressure mapping protrusions 401 can be adjusted according to actual needs to achieve different massage effects and support strengths. For example, in areas where a stronger massage effect is required, the number of pressure mapping protrusions 401, the protrusion height or the shape thereof can be increased to increase the massage intensity of the patella and its surrounding tissues; while in areas where a weaker massage effect is required, the number of pressure mapping protrusions 401, the protrusion height thereof or the distribution density thereof can be reduced accordingly to provide a softer massage experience. This flexible design enables the silicone rubber gasket to adapt to the needs and preferences of different users, providing more personalized and precise massage services.

[0045] from Figure 7 and Figure 10It can be seen that in actual application, the three groups of reinforcing ribs 6 divide the outer and inner edges of the gasket body 1 into three massage areas corresponding to the Heding point, the Nei Xiyan point and the Dubi point, and the two groups of reinforcing ribs 6 can limit the displacement of the patella. The design of these three massage areas fully takes into account ergonomics and Chinese medicine acupuncture point theory. The Heding point area is located just above the patella. Proper massage can promote blood circulation and relieve muscle tension around the patella; the Nei Xiyan point and Dubi point areas are located below the inner and outer sides of the patella, respectively. Massaging these areas helps relieve fatigue and discomfort in the knee joint. The provision of the reinforcing ribs 6 not only enhances the structural strength of the gasket body 1, but also guides the massage direction to a certain extent, ensuring that the massage force acts precisely on the target acupuncture points. At the same time, the structural support formed by the two groups of reinforcing ribs 6 can effectively limit the displacement of the patella during activities, protect the stability of the knee joint, and reduce the risk of sports injuries. This differentiated massage design, which combines ergonomics and traditional Chinese medicine theory, enables the silicone rubber gasket to provide a comfortable massage experience while also playing a positive health-care role.

[0046] In a specific application scenario, the gasket body 1, the curved transition structure 2, the differentiated massage structure 3, the raised support structure 4, and the reinforcing ribs 6 are integrally formed, all made of silicone rubber with a hardness range of 0 to 40 degrees. This integrated design not only ensures the gasket's integrity and structural strength, but also ensures a more secure connection between its components, making it less likely to loosen or damage. The choice of silicone rubber with a hardness range of 0 to 40 degrees is based on a comprehensive consideration of both human comfort and massage effectiveness. Silicone rubber within this hardness range is both soft enough to conform to the body's curves for a comfortable fit, and elastic enough to generate moderate pressure during massage, stimulating acupoints and achieving the desired massage effect. Furthermore, silicone rubber offers excellent wear and corrosion resistance, maintaining the gasket's performance and appearance over time, extending its service life. Therefore, this integrated design and the choice of silicone rubber material together constitute the core advantages of the differentiated massage silicone rubber gasket, ensuring both comfort and durability while providing effective massage.

[0047] Based on the above description, embodiment 1 further discloses a knee support device, including the above-mentioned differentiated massage silicone rubber gasket adapted for the patella.

[0048] The knee brace further includes a knee brace strap, one end of which is fixedly connected to one side of the silicone rubber gasket. The other end is equipped with an adjustment buckle for adjusting the tightness of the knee brace strap according to the user's knee circumference. The knee brace strap is made of elastic material, such as spandex or Lycra, to ensure comfort and a snug fit. The knee brace strap is also designed for breathability to reduce discomfort during prolonged wear.

[0049] The silicone rubber gasket and knee brace strap can be connected by sewing, gluing, or snapping to ensure a secure and stable connection. In practice, a connecting ring or strap can be provided on the edge of the silicone rubber gasket to securely connect it to one end of the knee brace strap. The adjustment buckle can be a common buckle, plastic buckle, or metal buckle, allowing for user adjustment.

[0050] In addition, the knee brace device may further include a Velcro to further secure the position of the silicone rubber gasket and the knee brace strap to prevent displacement during exercise. One side of the Velcro is attached to the knee brace strap, and the other side is attached to the silicone rubber gasket or the skin around the user's knee to ensure the stability and fit of the knee brace device.

[0051] Overall, the knee brace combines a differentiated massage silicone rubber gasket adapted to the patella with an adjustable knee brace strap to provide users with a more comfortable, fitted, and effective massage experience. Furthermore, the design of the knee brace strap and Velcro enhances the stability and practicality of the knee brace, making it suitable for various sports and daily wear scenarios.

[0052] In summary, the present invention utilizes a non-standard elliptical inner edge design for the gasket body 1, combined with a curved transition structure 2, to allow the silicone rubber gasket to more closely conform to the actual shape of the human patella. This design effectively reduces vibration and shaking during exercise, thereby improving the stability and comfort of the knee brace. Furthermore, through the design of a differentiated massage structure 3, the present invention provides a smooth transition of massage pressure around key acupoints such as the Heding, Neixiyan, and Dubi points. Furthermore, the hollowed-out portion of the knee contact surface, which is not fully filled, reduces weight and material costs. Furthermore, the combination of the main massage protrusions 301 and the gradient massage protrusions 302, made of silicone rubber of varying hardness, provides a more personalized massage experience tailored to individual needs. The main massage protrusions 301 precisely target the Heding point (midpoint of the upper edge of the patella), the Nei Xiyan point (inner depression of the patellar ligament), and the Dubi point (outer depression of the patellar ligament) around the patella. These key acupuncture points / pain points combine targeted Traditional Chinese Medicine acupuncture therapy with sports protective gear to help relieve knee weakness, alleviate medial pain, and improve lateral strain. The gradient massage protrusions 302, centered around the main massage protrusion 301, are arranged in a surrounding gradient, gradually decreasing the surface area in contact with the skin, creating a soothing transition in pressure for a more effective massage effect. The gradient protrusions also form a "micro-anchor array," increasing friction between the gasket and the skin and preventing dynamic patellar instability. The synergistic effect of the raised dot support structure 4 and the differentiated massage structure 3 creates a pressure mapping mechanism, precisely aligning the protrusion layout on the knee contact surface with the dot layout on the support surface, creating a controllable pressure transmission path. This allows the type and intensity of pressure applied to the patella and surrounding tissues to be tailored to the specific area. By adjusting the density, size, distribution surface area, and shape of the support protrusions, a different level of support can be achieved. Furthermore, the interaction between the knee contact and support surfaces achieves different massage effects. The reinforcing ribs 6 not only enhance the structural strength of the gasket body 1, preventing deformation during use, but also provide enhanced support for the patellar tendon and patellar support. Furthermore, taking ergonomic principles into consideration, the reinforcing ribs 6 also act like a patellar strap, limiting patellar displacement and allowing the knee joint to move within a safer range of motion, thereby reducing the risk of injury. The silicone rubber gasket is manufactured using a one-piece molding process, ensuring consistent quality throughout the gasket. The gasket is made of silicone rubber, which maintains good elasticity and hardness within a hardness range of 0 to 40 degrees. This material choice not only ensures the durability of the product, enabling it to withstand long-term use without damage, but also ensures comfort during use, providing a more pleasant experience for users.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
