Technical Field

[0001] The present disclosure relates to the technical field of sports protective gear, and in particular to a patella protection element and a knee pad assembly. Background Art

[0002] In real life, due to the complex structure of knee bones, cartilages and ligaments, people are prone to bumping and collisions during exercise, which may lead to injuries. Therefore, pads are usually filled in knee pads to provide some protection for the knees during exercise.

[0003] However, since a large part of knee injuries are closely related to people's improper exercise posture, such as excessive knee bending or inward rotation of the calf when the knee is bent, it will cause certain damage to the knee. In view of these situations, ordinary pads are not ideal for protecting the knees.

[0004] Therefore, those skilled in the art are in urgent need of providing a solution to correct the user's incorrect exercise posture, thereby protecting the knees from being damaged by exercise. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present disclosure provides a patella protection element and a knee brace assembly.

[0014] In one embodiment of the present disclosure, in the height direction, the length ratio of the base to the inner limiting member and the outer limiting member is 1:2.1 to 1:2.5.

[0015] In one embodiment of the present disclosure, the base is provided with a first massage point on the side facing the human body; and / or,

[0016] The inner limiter and the outer limiter are provided with a second massage point on the side facing the human body; and / or,

[0017] The base is provided with a third massage point on the side facing the human body, and the third massage point is located outside the first massage point.

[0018] In one embodiment of the present disclosure, the patella protection element has a plurality of the first massage points and the second massage points, and the first massage points and the second massage points are arranged in one-to-one correspondence with the muscle points around the patella of the human body.

[0032] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0037] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0038] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0039] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0040] It should be noted that the directional terms "up, down, inside, and outside" used in this article to describe the patella protection element are all based on the vertical center line of the human body when the human body is standing wearing the knee pad. The side close to the ground is the down side, the side away from the ground is the up side, the side close to the vertical center line of the human body is the inside, and the side away from the vertical center line of the human body is the outside.

[0041] In order to solve the problems existing in the prior art, a patella protection element and a knee pad assembly are provided.

[0042] First, the present disclosure provides a patella protection element, which is assembled with a knee pad body and then worn, and the patella protection element includes a base 1, an inner stopper 2, and an outer stopper 3. The base 1 is configured to fit with the bottom of the human patella when worn to support the patella; the inner stopper 2 is arranged at the inner end of the base 1 and extends upward, and when worn, it abuts against the inner side of the human leg to limit the inward displacement of the patella when the human body moves; the outer stopper 3 is arranged at the outer end of the base 1 and extends upward, and when worn, it abuts against the outer side of the human leg to limit the outward displacement of the patella when the human body moves; the hardness of the inner stopper 2 and the outer stopper 3 is greater than the hardness of the base 1.

[0043] It should be noted that the "displacement" mentioned in this article refers to the displacement of the patella relative to the center line of the leg bone when the user exercises after wearing the knee brace. If the displacement is within the allowable range, the human knee will not be injured. Once the displacement exceeds the allowable range, the knee will be damaged due to patella dislocation.

[0044] Specifically, in actual application, the patella protection element and the knee pad body are worn by the user after being assembled.

[0045] See also Figure 1 When a user wears the knee pad assembled with the patella protection element, the base 1 fits against the bottom of the human patella, and the inner limit piece 2 and the outer limit piece 3 at both ends of the base 1 also respectively abut against the inner and outer sides of the human leg, that is, the base 1, the inner limit piece 2 and the outer limit piece 3 surround the user's knee patella, thereby tightening the knee patella.

[0046] When the user is exercising, the base support 1 can support the patella of the knee. When the user's knee joint is impacted during exercise, the base support 1 can absorb shock and buffer the impact to reduce the damage to the knee caused by external force, while also reducing the impact on other bones or tissues in the joint.

[0047] In addition, the patella protection element provided by the present disclosure sets the bottom support 1 and the inner limiter 2 and the outer limiter 3 to different hardnesses, that is, the softer bottom support 1 is used to contact the bottom of the patella of the knee, which can not only ensure the comfort of the user, but also absorb the impact force received by the knee. The harder inner limiter 2 and the outer limiter 3 fit the two sides of the user's legs, which can better limit the displacement of the user's patella inward or outward relative to the leg bone, correct the user's wrong exercise posture in time, avoid the problem of user knee injury caused by excessive displacement, and ensure the safety of the user during exercise.

[0048] In one embodiment of the present disclosure, the base 1 is a silicone base, the inner limiter 2 is a silicone inner limiter, and the outer limiter 3 is a silicone outer limiter.

[0049] The patella protection element provided by the present disclosure is made of silicone material, which can absorb the impact force acting on the knee part well by utilizing the excellent energy storage performance of silicone material, and play a good protective role on the knee part. In addition, the preferred elastic performance of silicone material can also absorb part of the external force, play a role of shock absorption and buffering, and prevent the patella from being displaced due to excessive force, or causing cartilage damage.

[0050] It should be noted that, because nitrile rubber has similar compressibility and deformability as silicone rubber, in another embodiment of the present disclosure, the base, inner limiter, and outer limiter of the patella protection element may also be made of nitrile rubber.

[0051] Furthermore, in one embodiment, the base 1, the inner limiting member 2 and the outer limiting member 3 of the present disclosure are integrally formed.

[0052] Specifically, those skilled in the art can integrate the base 1 , the inner limiter 2 , and the outer limiter 3 of different hardness into a whole through a series of steps such as filling with liquid hot melt adhesive, spraying of coupling agent, drying, and forming of silicone layer.

[0053] It can be imagined that the patella protection component manufactured using an integrated molding process not only has high dimensional accuracy, but also high dimensional stability, making it difficult for the patella protection component to fall off during user use.

[0054] Of course, in actual application, other manufacturing processes can also be selected to manufacture the patella protection element. For example, the base, inner limit member and outer limit member can be independently processed and then fixed by bonding, welding or threaded connection.

[0055] In one embodiment of the present disclosure, the base 1 is a poorly arc-shaped base 1, and the inner limit member 2 and the outer limit member 3 are respectively connected to the two ends of the base 1, and first extend smoothly upward and outward and then extend upward and inward to form a preset gap between the two ends.

[0056] Continue to see Figure 1 The patella protection element provided by the present invention sets the base 1 to a poor arc shape, so that it can be precisely fitted to the lower end of the human patella, increase the contact area between the base 1 and the knee patella, and optimize the shock absorption effect of the base 1.

[0057] See also Figure 2 The bottom support 1, the inner limiting member 2 and the outer limiting member 3 are connected to form a U-shaped structure to better match the outer contour of the human patella and jointly tighten and protect the patella of the knee.

[0058] In one embodiment of the present disclosure, Figure 2 As shown, in the height direction, the length ratio L2:L1 of the base 1 and the inner limiting member 2 and the outer limiting member 3 is 1:2.1 to 1:2.5.

[0059] In this way, the length dimension between the bottom support and the inner and outer limiters in the patella protection element in the height direction can be well matched with the human patella. In other words, this proportional relationship conforms to the structure of the human knee, and can make the bottom support 1, the inner and outer limiters 2 and the outer limiters 3 in the patella protection element fit well around the human knee, thereby improving the wearing comfort of the user and better protecting the knee.

[0060] Specifically, in one embodiment, L1 of the present disclosure is 9.12 cm, and L2 is 3.98 cm. In another embodiment, L1 is 7.45 cm, and L2 can be 3.24 cm. This article only exemplifies the length in the height direction between the bottom support and the inner limiter and the outer limiter in the patella protection element, and those skilled in the art can adjust it based on the actual size of the patella protection element.

[0061] Combination Figure 1 and Figure 2In one embodiment, the base 1 of the present invention is provided with a first massage point 4 on the side facing the human body, the inner limit member 2 and the outer limit member 3 are provided with a second massage point 5 on the side facing the human body, and the base 1 is provided with a third massage point 6 on the side facing the human body, and the third massage point 6 is located on the outside of the first massage point 4.

[0062] Combination Figure 1 and Figure 2 The base 1 has four first massage points 4, and the combination of the four first massage points 4 mainly massages the outer support band, the inner support band and the knee ligament below the knee.

[0063] There are eight second massage points 5 on the inner limiter 2 and the outer limiter 3. The combination of the eight second massage points 5 is mainly used to press the vastus lateralis and vastus medialis muscles of the legs, thereby relieving thigh muscle fatigue.

[0064] There are four third massage points 6 on the base 1. The combination of the four third massage points 6 mainly assists the first massage points 4 in pressing the leg support bands and ligaments to relax the leg support bands and ligaments and prevent them from being strained.

[0065] It should be noted that, in the above-mentioned embodiment, the patella protection element of the present invention has a combination structure of the first massage point, the second massage point and the third massage point to produce multiple massage effects on the human body. In other embodiments, the patella protection element of the present invention may include only any one of the first massage point, the second massage point and the third massage point, or a combination of any two of the three, such as the first massage point and the second massage point, the first massage point and the third massage point, or the second massage point and the third massage point.

[0066] In addition, the above embodiment only exemplarily provides the number of the first massage point, the second massage point, and the third massage point, but is not limited thereto. Based on actual massage point requirements, the specific number of the above three massage points can be adaptively adjusted.

[0067] In summary, the patella protection element disclosed in the present invention can effectively relieve fatigue of related tissues by reasonably arranging massage points on the inner limit member 2, the outer limit member 3 and the base 1 to press the support band, ligaments and muscles around the knee.

[0068] At the same time, the patella protection element is provided with a plurality of raised massage points on the side that fits the human leg, which is also conducive to the fit of the patella protection element to the leg, making it less likely to slip, and further improving the patella protection element's ability to tighten the patella of the knee.

[0069] Further, see Figure 1 and Figure 2The protrusion height of the first massage point 4 is greater than the protrusion height of the second massage point 5, and the protrusion height of the second massage point 5 is consistent with the protrusion height of the third massage point 6.

[0070] Since the first massage point 4 and the second massage point 5 massage locations are different, the first massage point 4 mainly presses the leg support band and ligaments, while the second massage point 5 presses the vastus medialis and lateral muscles.

[0071] Compared with the vastus medialis lateralis muscles, the leg support band and ligaments are more difficult to be pressed by the massage points. Therefore, if the massage points for pressing the leg support band and ligaments are set too small, it is difficult to achieve the ideal massage effect. On the other hand, the vastus medialis lateralis muscles are easily in contact with the second massage point 5. If the second massage point 5 is set too large, it will cause muscle discomfort to the user.

[0072] Therefore, the patella protection element provided by the present invention has a protruding height of the first massage point 4 that is greater than the protruding height of the second massage point 5, which can better achieve an ideal massage effect at the first massage point 4 and the second massage point 5 and improve the user experience.

[0073] In one embodiment, the outer side of the base 1 of the present disclosure further has a first side support portion 7 and a second side support portion 8 extending outward, and the first side support portion 7 and the second side support portion 8 are symmetrically arranged relative to a center line extending in the height direction of the base 1.

[0074] During actual use, due to frequent twisting of the knee, the patella protection element and the patella may be easily misaligned, which weakens or even renders the protective effect of the patella protection element on the patella ineffective. For this reason, the patella protection element disclosed in the present invention also has a first side support portion 7 and a second side support portion 8 arranged on the outer side of the base 1.

[0075] After the user wears the knee pad assembled with the patella protection element, when the human body is moving, the first side support part 7 and the second side support part 8 are bent to fit the two sides of the knee joint respectively, thereby effectively fixing the position of the patella protection element relative to the knee and preventing it from slipping.

[0076] In addition to the above-mentioned patella protection element, the present disclosure also provides a knee pad assembly, which includes a knee pad body and the above-mentioned patella protection element, the knee pad body is configured to be worn on the knee portion of a human body; the patella protection element is disposed on the knee pad body, and the patella element is the above-mentioned patella protection element. It should be noted that since the knee pad assembly of the present disclosure is assembled with the above-mentioned patella protection element, it has all the technical effects of the patella protection element, which will not be described in detail herein.

[0077] It should be noted that the kneepad body of the present invention can be a cylindrical structure, which can be directly put on the knee when the user wears it. It can also be a sheet structure, which can be tied to the knee and fixed when the user wears it.

[0078] The patella protection element of the present invention can be assembled with the knee pad body by sewing the patella protection element onto the knee pad body, or by reserving an installation chamber with an opening on the knee pad body, and during assembly, the patella protection element only needs to be inserted into the installation chamber.

[0079] For better understanding, refer to Figure 1 and Figure 2 , combining an application scenario to introduce the method of using the knee pad assembly of the present invention.

[0080] The user wears the kneepad assembled with the patella protection element on the knee, and makes the combination of the bottom support 1, the inner limiter and the outer limiter surround the patella of the human body.

[0081] When the user is exercising, the bottom support 1 will support the patella of the user's knee, and when the user is running, part of the impact force on the knee will be absorbed by the bottom support 1.

[0082] In addition, the inner limit member 2 and the outer limit member 3 limit the inward or outward displacement of the patella relative to the leg bone, which promptly corrects the user's incorrect exercise posture, avoids the user's knee injury caused by excessive displacement, and ensures the user's safety during exercise.

[0083] At the same time, the first side support part 7 and the second side support part 8 on the base 1 fit with both sides of the knee, so that the knee brace component will not be misaligned with the patella of the knee as the user's knee twists.

[0084] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
