[0001] The utility model belongs to the field of sports equipment and rehabilitation medical technology, especially relates to a patella belt. BACKGROUND

[0002] As a kind of sports protective equipment specially designed for protecting knee joint, patella belt has wide application in sports medicine and rehabilitation field.The core function is to stabilize patella, reduce the pressure when moving, and limit the abnormal movement of patella through moderate pressure and support structure, so as to relieve joint pressure, promote blood circulation and assist the rehabilitation treatment of knee joint disease.However, with the continuous development of sports science and the increasing performance requirements of consumers for sports protective equipment, the existing patella belt gradually exposes many deficiencies in preparation process, material selection and structure design, and needs to be improved through technical innovation.

[0003] At present, the mainstream patella belt on the market adopts flat knitting preparation process.Flat knitting as a traditional knitting method is completed by reciprocating movement of horizontal needle, and flat knitting technology is known for its flexibility, which can weave complex shape and segmented pressure structure, so as to accurately wrap knee joint and provide stable support for patella and surrounding tissue.This kind of knitting method realizes segmented pressure through three-dimensional knitting, simulates the fixing effect of muscle on joint, so as to provide close wrapping and stability, and has been widely applied in sports protection field.

[0004] However, the patella belt knitted by flat knitting machine usually adopts elastic materials such as spandex and rubber to provide necessary support and wrapping feeling.However, these materials have limitations in elasticity recovery and durability.After long time use, the materials are easy to fatigue and deform, resulting in the decrease of supporting force, which cannot continuously and effectively stabilize patella.In addition, the flexibility of flat knitting process in material selection is relatively limited, and it is difficult to integrate more high-performance or functional yarns to meet the diversified performance requirements of consumers for patella belt.

[0005] In addition, the shape and size of flat knitting patella belt are fixed in the preparation process, however, the knee joint morphology and size of different users are different, and the fixed shape support layer is difficult to completely adapt to the knee joint structure of all users.This leads to the situation that the patella belt may have excessive local pressure or insufficient support when providing support, which affects the protection effect and user's comfort, and the preparation process of flat knitting patella belt is relatively complex, and the production efficiency is relatively low.

[0006] Therefore, the existing patella belt knitted by flat knitting machine has many defects in performance and structure, which is difficult to meet the increasing performance requirements of consumers for sports protective equipment. UTILITY MODEL CONTENT

[0007] Therefore, the utility model aims at solving the technical problem that the existing patellar strap is prone to fatigue deformation due to the use of elastic material in the flat knitting process, the supporting force decreases, the material selection flexibility is limited, and it is difficult to integrate high-performance silk threads, and the fixed shape and size are difficult to adapt to the knee joint structure of different users, resulting in uneven support and poor comfort.

[0016] Further, the support layer comprises a support main body, and a third arc-shaped recess for supporting the patella is arranged on the support main body.

[0017] Further, the support layer is arranged in a whole circular arc shape, the projection length of the support layer on the woven surface layer is L2, the length of the woven surface layer is L1, and the ratio of L2 to L1 is in the range of 0.3-0.65.

[0036] like Figs. 1-4 As shown, this application discloses a patellar strap, including a main body 100 and a strap 200. The strap 200 can bind and fix the main body 100 to the patella. The main body 100 includes a woven surface layer 1, a support layer 2, and a bottom layer 3 arranged sequentially. The woven surface layer 1 has a complete circumferential cut edge. The woven surface layer 1, the support layer 2, and the bottom layer 3 are integrated by a locking structure 4 provided around their periphery. In the example of this application, the woven surface layer 1 is prepared by cutting a cylindrical structure 300 woven by a circular knitting machine.

[0037] The patellar brace disclosed in this application has a main body 100 structure composed of a woven surface layer 1, a support layer 2, and a bottom layer 3 bonded together by a locking structure 4. The woven surface layer 1 is manufactured using circular knitting technology, allowing for greater flexibility in yarn type and weaving density. Fig. 5As shown, a cylindrical structure 300 woven by a circular knitting machine is precisely cut to form multiple woven surface layers 1 adapted to different knee joint sizes. The woven surface layers 1, support layers 2, and a soft, breathable bottom layer 3 that directly contacts the skin are securely bonded together as a whole by a locking seam around the perimeter, ensuring the stability and durability of the main body 100 during movement. Furthermore, the strap 200 design allows for easy fixation to the patella, effectively limiting abnormal patellar movement during exercise, dispersing local pressure generated by movement, and mitigating joint impact. The patellar strap disclosed in this application represents a technological innovation based on traditional flat knitting technology, and also optimizes material selection and structural design. By incorporating different types of yarn and knitting density, it achieves a comprehensive improvement in production efficiency, functionality, and aesthetics, meeting consumers' ever-increasing demands for support, comfort, and durability in sports protective equipment. It is easy to operate and reliable in use.

[0038] As a preferred example of this application, the woven surface layer 1 is inlaid with yarns of various functions or colors. In the examples of this application, such as... Fig. 6 The present application provides a specific example of a patellar brace. First, a circular knitting technique is used to precisely weave various yarns with different properties into a cylindrical structure 300 with specific colors and densities. During the weaving process, yarns with various functions or colors are introduced, so that the woven surface layer not only presents a rich and colorful appearance, but also endows the surface layer with multiple functions such as antibacterial properties, breathability, and enhanced elasticity. For example, the precise control of the yarn arrangement and density achieves the simultaneous improvement of yarn function and aesthetics. Then, the woven cylindrical structure 300 is precisely cut to form the woven surface layer 1. After cutting, the surface layer retains the original color and functional characteristics of the cylinder. Then, it is firmly bonded to the support layer 2 and the bottom layer 3 through the surrounding locking structure 4 to form an integral structure.

[0039] This design allows the patellar strap described in this application to present a personalized and aesthetically pleasing appearance while achieving a comprehensive effect of antibacterial properties, breathability, and enhanced elasticity.

[0040] As a preferred example of this application, a connecting device 7 is provided on the side of the woven surface layer 1 away from the bottom layer 3. The connecting device 7 is used to connect and fix the strap 200. In this example, by providing the connecting device 7 on the side of the woven surface layer 1 away from the bottom layer 3, the connecting device 7 is integrated with the woven surface layer. By changing the density and strength of the connection of the fabric, the connecting device 7 is firmly connected to the woven surface layer 1. This allows the strap 200 to achieve a firm mechanical lock after passing through the connecting device 7, so that the strap 200 will not shift or loosen due to external force pulling or movement friction during movement. The operation is convenient and the use is reliable. When wearing and adjusting the patellar strap, the user only needs to perform a simple operation to fix the strap through the connecting device.

[0041] As a preferred example of this application, the connecting device 7 includes a connecting strap 5, which is sewn or woven to the woven surface layer 1. A connecting hole 501 is provided on the connecting strap 5, and a connecting ring 6 passes through the connecting hole 501 and connects to the connecting strap 5. As a specific example of this application, two connecting devices 7 are provided, distributed at opposite ends of the woven surface layer 1 along its length. Each connecting device 7 consists of a connecting strap 5 and a connecting ring 6. The connecting strap 5 is folded in half and sewn to the woven surface layer 1, forming a connecting hole 501 between the folds, ensuring the stability and durability of the connection. The connecting ring 6 passes through the connecting hole 501 and connects with the connecting strap 5 to form a flexible and stable connection structure. This structure not only allows the strap 200 to easily pass through the connecting ring 6 and achieve quick adjustment and fixation, but also, with the two connecting devices 7 respectively arranged at both ends of the woven surface layer 1, the patellar strap can evenly distribute the pressure from all sides when worn, effectively avoiding excessive local force. At the same time, the entire patellar strap always remains tightly fitted to the knee joint during movement, effectively reducing discomfort or injury caused by excessive local pressure and movement impact.

[0042] As a preferred example of this application, the support layer 2 is integrally made of elastic material and is disposed between the woven surface layer 1 and the bottom layer 3, with the support layer 2 protruding towards the bottom layer 3. In this example, the support layer 2 is made of silicone, sponge, highly elastic polymer, or other preferred elastic material, ensuring that it maintains good elasticity and resilience during repeated deformation. The integrated manufacturing process eliminates the loosening or detachment problems that may be caused by layering or splicing in traditional multi-layer structures, making the overall structure more robust and durable. By placing the support layer 2 between the woven surface layer 1 and the bottom layer 3 and having the support layer 2 protrude outward towards the bottom layer 3, not only is the overall structural strength enhanced, but also, by closely conforming to the natural curve of the knee joint, the support layer 2 can automatically adjust its shape when the knee joint bends or extends, thereby achieving continuous and stable support for the patella and surrounding tissues.

[0043] This design enables the patellar band support layer 2 to adapt to the flexion and extension of the knee joint during knee movement, providing precise and balanced support. This allows the patellar band to effectively disperse and absorb external impacts during movement, reducing the risk of discomfort or injury caused by excessive local stress, and further improving the product's durability and stability.

[0044] As a preferred example of this application, the support layer 2 includes a support body 201, on which a third arc-shaped recess 202 for supporting the patella is provided. In this example, the support body 201 is made of an integrally molded elastic material, and the third arc-shaped recess 202 is specially designed and provided on the surface of the support body 201. The shape and depth of the recess are carefully adjusted to conform to the physiological curve of the patella, allowing the patella to naturally embed into the recess during wear, thereby achieving precise and stable support. At the same time, the support body 201 is integrally connected with the woven surface layer 1 and the bottom layer 3 through a strong composite process, avoiding the loosening or falling off problems that may occur due to multi-layer splicing in traditional structures, further improving the durability and stability of the entire product.

[0045] This design fully considers ergonomic requirements. By adjusting the geometric parameters of the concave part and the elasticity of the material, it can adapt to the knee joint shape and movement needs of different users, thus making the patellar strap more widely applicable and providing a superior user experience in sports protection and rehabilitation assistance.

[0046] As a preferred example of this application, the support layer 2 is generally arc-shaped, allowing it to better conform to the natural physiological curve of the knee joint. The projection length of the support layer 2 on the woven surface layer 1 is L2, and the length of the woven surface layer 1 is L1. The ratio of L2 to L1 ranges from 0.3 to 0.65. In this example, the support layer 2 is designed as an arc-shaped structure, with a third arc-shaped recess 202 formed on its side near the patella. The ratio of the projection length L2 of the support body 201 on the woven surface layer to the total length L1 of the woven surface layer is optimized and limited to a range of 0.3 to 0.65, preferably 0.45, to ensure that the support layer can fully cover the patella and its surrounding key areas without being too long and affecting the flexibility of the knee joint.

[0047] As a preferred example of this application, a first arc-shaped recess 8 is provided at the upper edge of the main body 100 near the middle. In this example, by cutting a notch at the middle position on one side of the woven surface layer 1 during cutting, the bottom layer 3 combines the support layer 2 with the woven surface layer 1 through the locking structure 4, thus forming a first arc-shaped recess 8 at the middle position of the upper edge of the combined patellar strap main body 100. The concave direction of the first arc-shaped recess 8 is consistent with the concave direction of the third arc-shaped recess 202, thereby forming a concave area in the overall structure of the patellar strap so as to avoid the patella protruding from the position corresponding to the leg when worn.

[0048] This design takes into full account the physiological structure of the knee joint and patella, as well as the complexity of knee movements during exercise. By providing ample space in the concave area, the patella is not compressed by external forces during exercise, while maintaining a good fit between the patellar strap and the knee joint, thus achieving personalized support and protection. This structure further improves wearing comfort and safety while ensuring overall support stability.

[0049] As a preferred example of this application, a second arc-shaped recess 9 is provided at the lower edge of the main body 100 near the middle. The concave direction of the second arc-shaped recess 9 is opposite to that of the first arc-shaped recess 8. In this example, by providing a second arc-shaped recess 9 at the lower edge of the composite main body 100, and with its concave direction opposite to that of the first arc-shaped recess 8, the patellar strap can better conform to the lower contour of the knee joint, thereby forming a complementary upper and lower concave area. When worn, this concave area allows the patella to naturally lie within the upper concave area, while the lower concave area conforms to the lower curve of the knee joint, thus achieving balanced support for the entire knee joint.

[0050] This design takes into full account the physiological structure of the human knee joint and patella and the dynamic changes during movement. By setting complementary concave structures at the upper and lower ends of the main body 100, it ensures that the patellar band provides continuous and stable support during movement, while avoiding discomfort caused by local pressure, and ensuring that the patella is always in a stable and comfortable position during movement.

[0051] As a preferred example of this application, the locking structure 4 connects and fixes the woven surface layer 1 and the bottom layer 3 with continuous or intermittent sutures. In the example of this application, the outermost edge of the bottom layer 3 is folded over the woven surface layer 1 and covers the side of the woven surface layer 1 away from the bottom layer 3. Then, the outer periphery of the woven surface layer 1 and the bottom layer 3 are continuously sewn together with V-shaped stitches to form a stable locking structure 4. This design not only enhances the overall structural stability of the patellar band but also improves its aesthetics and durability.

[0052] In the example of this application, the locking structure 4 can also be implemented by a third connector to achieve the sewing and locking of the woven surface layer 1 and the bottom layer 3, which will not be elaborated further here.

[0053] In the example of this application, the strap 200 is secured by Velcro and textured adhesive. In this example, the strap 200 includes a strap strip 10 with horseshoe-shaped adhesive portions 11 at opposite ends. The remaining portion of the strap strip 10 is textured. In use, one end of the strap strip 10 is connected to the textured surface via the adhesive portion 11, allowing the strap 200 to be detachably secured to a connecting device 7. The other end of the strap strip 10 passes through the connecting ring 6 of another connecting device 7 and is then wrapped back for adhesive fixation, thereby securing the patellar strap body 100 to the lower end of the patella.

[0054] By using Velcro and textured adhesive methods, the use of the patellar strap 200 becomes more convenient and flexible. Users can quickly adjust the tightness and position of the strap as needed. At the same time, the strap strip 10 can pass through the connecting ring 6 of the connecting device 7 and wrap back to stick, further enhancing the stability of the patellar strap body and ensuring its effective support and protection during movement.

[0055] The patellar strap disclosed in this application uses circular knitting technology to prepare the woven surface layer 1. This allows for greater flexibility in yarn types and weaving density, enabling the incorporation of yarns with various functions or colors. This not only enriches the product's appearance but also provides multiple functions such as antibacterial properties, breathability, and enhanced elasticity, meeting consumers' dual demands for both functionality and aesthetics in sports protective equipment. It avoids the performance degradation caused by limited material selection in traditional flat knitting processes. Furthermore, this application provides a first arc-shaped recess 8 and a second arc-shaped recess 9 at the upper and lower edges of the patellar strap body 100, respectively. This allows the patellar strap to naturally conform to the upper and lower contours of the knee joint when worn, effectively dispersing local pressure generated during exercise and enhancing wearing comfort and stability. Furthermore, by optimizing the shape and material selection of the support layer 2, the support layer 2 is integrally molded using elastic material and has a third arc-shaped recess 202 on its surface. This allows the support layer 2 to precisely avoid the natural curve of the patella while providing continuous and stable support during knee joint movement, avoiding the loosening or detachment problems caused by the layering and splicing of traditional support structures. In addition, the patellar band described in this application can provide stable support for patients undergoing rehabilitation treatment for knee joint diseases such as sports injuries, arthritis, and patellar chondromalacia, reducing abnormal patellar movement during movement and lowering the risk of secondary injury due to patellar instability. The highly elastic woven surface layer can closely conform to the knee joint skin, flexibly extending and contracting with knee joint movement. The precise support of the support layer helps patients better complete rehabilitation movements, improves the effectiveness of rehabilitation training, and accelerates the recovery of knee joint function.

[0056] The patellar strap described in this application, through the optimized design of the above structure, significantly improves the performance of the patellar strap, and while ensuring support stability, significantly enhances the wearing comfort, ease of use and durability of the patellar strap.

[0057] The embodiments of this application have been described above with reference to the accompanying drawings.

This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
