Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of technical field of sports protector, especially a knee protector assembly of stabilizing patella, can be supported patella by supporting reinforcement part to reduce excessive displacement of patella in the process of movement, and then play the role of sports protection. BACKGROUND

[0002] Patella, commonly known as knee bone, is the largest sesamoid bone in the human body, located in the quadriceps tendon, and is an important part of the knee extension device. One of the characteristics of patella is that it can conduct and enhance the quadriceps muscle, effectively completing the knee extension action. In addition, patella can also help maintain the stability of the knee joint, protect the knee joint, and play the role of a pulley during knee extension. Through the intermediate structure of its knee extension device, patella can transmit the tensile force generated by the quadriceps muscle to the patellar tendon, increase the lever arm of the knee flexion and extension axis point, and thus increase the moment of the quadriceps muscle.

[0003] However, patella is also prone to sports injuries due to its ability to produce multidirectional displacement. When the body performs high-intensity movements such as jumping, squatting, etc., the patella will bear a large amount of pressure and friction, and long-term and frequent such movements will increase the risk of patellar strain. In addition, improper movement posture and technique, as well as insufficient or unbalanced muscle strength around the patella, can also increase the likelihood of patellar injury.

[0004] In order to reduce the risk of patellar sports injury, people should arrange training plans reasonably during exercise, pay attention to the correctness of movement posture and technique, and strengthen the muscle strength around the patella. If symptoms of patellar injury occur, medical treatment should be sought in a timely manner, and symptomatic treatment and rehabilitation training should be performed.

[0005] Prior art one: Korean patent KR102412073B1 discloses a knee protector including a body surrounding the knee, a binding member connecting the body to wrap the knee, and a V-shaped traction member used in the process of installing the body on the knee. The body is made of a material with elasticity to wrap the knee in a compressed state, the binding member and the traction member are attached to the surface of the body to form a ring, and the pressing part of the user protruding from the edge of the hole compresses the knee and exposes the patella to the hole to prevent patellar dislocation.

[0006] Prior art two: Korean patent KR1020220054064A adds an active reinforcement body to the technical solution of Korean patent KR102412073B1, which has a structure in coordination with the raised parts. The active reinforcement body includes hinged curved upper and lower supports. The active reinforcement body has a structure that can be spaced a certain distance from the condyle of the wearer, so that the active reinforcement body is directly connected to the condyle without applying pressure. The active reinforcement body maximally reduces damage to the cruciate ligament around the knee joint, prevents the knee joint from being twisted due to excessive movement, and reduces the friction applied to the patella when the knee joint is unfolded and folded.

[0007] In the technical solutions of the above two patents, since the traction member 40 is in a lateral V shape, it can resist the displacement of the patella by horizontal force, but the lateral expansion structure of the traction member makes it less effective in supporting the patella in the up-down direction. In addition, the reinforcement and pressing of the patella come from the protruding pressing part 22 on the edge of the hole 21 of the connecting body 20, so that the traction force on the pressing part 22 is small during the traction of the traction member 40, which also leads to poor reinforcement and support effect of the whole structure.

[0008] Prior art three: Korean patent KR1020210047692A discloses a knee compression band 110 including a compression band body 111 formed in a cylindrical shape, a patella covering band 113 provided in the front central area of the compression band body 111 to support the patella (A) and the compression band body. 111) is provided in the middle area of the back of the cap band 115 to support the knee cap, and a plurality of attachment members (116, 116a, 116b) are provided on the front and rear surfaces of the compression band body 111, and the back of the compression band body 111 is provided with a mounting ring 118 for fixing the position of the cross band 120. The cross band 120 is connected to the front of the knee compression band 110 in an inclined direction to control the area of contact between the cartilage and the patella by pressing the patella upward; it is provided at the upper end of the rear side of the knee compression band 110 and is connected to the cross band 120, and includes ring pads 130, 140 and 150 for adjusting the angle of pressing the patella in the inclined direction.

[0009] In the technical solution of this patent, although the patella is lifted upward by the cross band 120, and the patella is also pressed and lifted in the horizontal direction by the cooperation of the ring pads 130, 140 and 150 with the cross band 120, thereby protecting the patella in all directions. However, this technical solution has a plurality of belt ring insertion structures, which are relatively complex and very inconvenient to wear. Utility model content

[0073] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0074] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0075] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0076] Example 1:

[0077] like Figures 1-3 As shown, the knee brace assembly for stabilizing the patella includes a main elastic plate 10 and a U-shaped anti-dislocation elastic plate 20. The main elastic plate 10 includes a posterior central plate 11, a left strap plate 12, and a right strap plate 13. Both the left strap plate 12 and the right strap plate 13 include side plates 1 and upper straps 2 and lower straps 3 spaced apart from each other. The anti-dislocation elastic plate 20 includes a connecting plate 4 and two traction straps 5, with the connecting plate 4 connected to either the left strap plate 12 or the right strap plate 13. The inner side of the anti-dislocation elastic plate 20 has an outward-facing, protruding U-shaped pressure pad 21.

[0078] like Figures 1-5As shown, when worn, the rear central piece 11 is located at the rear side bending part of the knee, and the left and right strap pieces 12 and 13 wrap around the knee. The free ends of the two upper straps 2 are attached to form an upper double-layer part a, and the free ends of the two lower straps 3 are attached to form a lower double-layer part b. The left and right strap pieces 12 and 13 together form a front piece for wrapping around the front side of the knee. The upper double-layer part a is located on the upper side of the patella, and the lower double-layer part b is located on the lower side of the patella. Once the main elastic piece 10 is stretched and fixed, it will always maintain the compression state of the knee due to the accumulated elasticity. At this time, the strap edges of the left and right strap pieces 12 and 13 will tightly wrap around the edges of the patella, effectively preventing the displacement of the patella.

[0079] Then, the anti-displacement elastic piece 20 is pulled towards the hole structure c, the connecting piece 4 covers part of the outer surface of the front piece, and the traction belt 5 is attached to the outer surface of the front piece. The inner contour of the anti-displacement elastic piece 20 is adapted to the hole structure c without blocking the hole structure c, and the "U"-shaped pressing pad 21 is adapted to the three side edges of the hole structure c to surround the edges of the hole structure c and be located on the periphery of the hole structure c.

[0080] Exposing the patella through the hole structure c reduces the friction of the protector on the patella, and the hole edges pressurize the edges of the patella, reducing the possibility of displacement of the patella. Unlike the traditional method of directly providing a hole structure c on the main body to expose the patella, the hole structure c in this embodiment is formed by the abutment of the left and right strap pieces 12 and 13, so it can be adaptively adjusted according to the leg structure and size of each person, so that the center of the compression part can coincide with the center of the patella as much as possible, improving the anti-displacement holding while maintaining a comfortable wearing state.

[0081] Further, the upper and lower double-layer parts a and b can further strengthen the holding of the hole structure c, and further strengthen the restriction of the upper and lower positions of the patella, which has a positive effect on the protection of the patella and its surrounding soft tissues. The abutment position of the left and right strap pieces 12 and 13 on the front side of the knee also changes the traditional mode of abutment position on the rear side in the traditional knee pad, avoiding friction on the skin at the bending part of the knee during movement.

[0082] In addition, the pulling of the anti-displacement elastic piece 20 can further resist the direction of displacement of the patella during knee movement, and the "U"-shaped pressing pad 21 can further increase the pressure on the edges of the patella, strengthening the support of the patella, thereby improving the effect of preventing displacement of the patella.

[0083] As shown in the drawings, Figures 1-3As shown in the embodiment, one side edge of the abutment piece 4 of the anti-dislocation elastic piece 20 is connected to the junction of the side piece 1 and the rear central piece 11. The anti-dislocation elastic piece 20 is covered on the outer side of the left or right girdle piece 12 or 13. The anti-dislocation elastic piece 20 is attached to the outer surface of the front piece after being pulled by the transverse extension.

[0084] The anti-dislocation elastic piece 20 is located in the direction of patellar dislocation in use. When the protector is worn on the knee, the anti-dislocation elastic piece 20 is pulled in the direction opposite to the dislocation of the patella. The "U"-shaped pressure pad 21 is located on the side of the dislocation direction. By applying a pressing force to the patella in the dislocation direction towards the body and the outer periphery of the protruding patella, the dislocation of the patella can be prevented.

[0085] As shown in FIGS. Figures 1-2 , 6, the rear central piece 11 comprises an upper piece 111, a middle piece 112 and a lower piece 113 connected to each other. The thickness of the middle piece 112 is thinner than that of the upper piece 111 and the lower piece 113, and the fabric elasticity of the middle piece 112 is greater than that of the upper piece 111 and the lower piece 113. Preferably, the fabrics of the upper piece 111 and the lower piece 113 are consistent with those of the left girdle piece 12 and the right girdle piece 13. The thinner and more flexible middle piece 112 is located at the knee fossa on the rear side of the knee after being worn, which can make the wearing more comfortable. Moreover, it is more suitable for the bending process of the knee. Further, the middle piece 112 is provided with air holes, which can further improve the comfort.

[0086] Preferably, the lower edge of the upper piece 111 is a concave curve with the middle part rising upwards, and the upper edge of the lower piece 113 is a concave curve with the middle part sinking downwards, so that the middle piece 112 has a structure of being wide in the middle and narrow on both sides. This structure is in line with ergonomics, and is more conducive to the transverse stretching of the rear central piece 11.

[0087] Preferably, as shown in Figure 1 , the extension length of the two traction belts 5 is greater than that of the upper girdle 2 and the lower girdle 3 of the left girdle piece 12 or the right girdle piece 13 on the same side. Thus, the anti-dislocation elastic piece 20 is completely covered on the outer side of the girdle piece on the same side and attached to the girdle piece on the opposite side, thereby improving the relative holding force.

[0088] Preferably, the outer surface of the left girdle piece 12 and the right girdle piece 13 is in a velvet form. The inner side of the upper girdle 2 of one girdle piece and the lower girdle 3 of the other girdle piece are provided with adhesive parts. In one of the upper double-layer part a and the lower double-layer part b, the girdle of the left girdle piece 12 is located on the outer side of the girdle of the right girdle piece 13. In the other of the two, the girdle of the left girdle piece 12 is located on the inner side of the girdle of the right girdle piece 13. By alternating up and down, left and right pulling is realized, thereby holding the patella and improving the extrusion force on the patella.

[0089] Preferably, vertical support bars 7 are provided at the junctions of the rear central panel 11 with the left strap panel 12 and the right strap panel 13. The vertical support bars 7 are made of elastic material with proper elastic modulus, which can enable the vertical support bars 7 to bend together with the bending of the knee but maintain certain rigid support strength. With the repeated folding and unfolding of the articulation of the knee joint, the vertical support bars 7 can limit the knee position in the transverse position, inhibit the transverse displacement of the patella to a certain extent, and prevent the knee from being excessively bent, while restoring to the original state when the folded knee is unfolded, assisting the extension movement of the knee.

[0090] As shown in Figure 3 The lower edge of the upper strap 2 is transitioned to the upper edge of the upper strap 2 by a circular arc edge f, so that the hole structure c is an inner contour round or elliptical structure, which is more suitable for the convex patella shape, so that the compression is more targeted, and the wearing comfort is also improved.

[0091] The extension length of the two upper straps 2 is greater than the extension length of the two lower straps 3. The upper straps 2 are used to be fastened on the upper side of the knee near the thigh position, and the lower straps 3 are used to be fastened on the lower side of the knee near the calf position. Therefore, such difference in extension length can better adapt to the leg structure, so that the wearing is more comfortable and comfortable.

[0092] As shown in Figure 1 The upper and lower edges of the main elastic panel 10 are both continuous curves with concave middle. This streamline structure can also better adapt to the wrinkles of the skin after the knee is bent, so that the wearing is more comfortable.

[0093] Embodiment Two:

[0094] As shown in Figures 7-8 The knee brace assembly for stabilizing the patella provided by the present embodiment is basically consistent with the knee brace assembly for stabilizing the patella in embodiment one in structure, and the only difference is that the position of the "U"-shaped dislocation prevention elastic panel 20 is different. Therefore, the stretching direction is different, and the attachment position area is different. Only the differences between the two will be further described below, and the same parts will not be repeated.

[0095] As shown in Figure 7As shown, the patellar stabilizing knee brace assembly provided in this embodiment includes a main elastic plate 10 and a U-shaped anti-dislocation elastic plate 20. The main elastic plate 10 includes a posterior central plate 11, a left strap plate 12, and a right strap plate 13. Both the left strap plate 12 and the right strap plate 13 include side plates 1 and upper straps 2 and lower straps 3 spaced apart from each other. The anti-dislocation elastic plate 20 includes a connecting plate 4 and two traction straps 5, the connecting plate 4 being connected to either the left strap plate 12 or the right strap plate 13. The inner side of the anti-dislocation elastic plate 20 is provided with an outward-facing, protruding U-shaped pressure pad 21.

[0096] One side edge of the connecting piece 4 is connected to the lower side edge of the left strap piece 12 or the right strap piece 13. The anti-dislocation elastic piece 20 is located on the lower side of the left strap piece 12 or the right strap piece 13, with the opening of the "U"-shaped pressure pad 21 facing downward. The anti-dislocation elastic piece 20 is extended and pulled upward and attached to the outer surface of the front piece.

[0097] like Figures 7-8 As shown, when worn, the posterior central piece 11 is located at the posterior bend of the knee, while the left and right strap pieces 12 and 13 wrap forward around the knee. After the free ends of the two upper straps 2 are attached together, the free ends of the two lower straps 3 are attached together, and the left and right strap pieces 12 and 13 together form the anterior piece to wrap around the front of the knee and form a perforation structure c for exposing the patella.

[0098] Then, the anti-dislocation elastic sheet 20 is pulled towards the hole structure c, and the connecting sheet 4 covers a portion of the outer surface of the front sheet, while the traction band 5 is attached to the outer surface of the front sheet. The inner contour of the anti-dislocation elastic sheet 20 is adapted to the hole structure c without obstructing it, and the shape of the "U"-shaped pressure pad 21 is adapted to the three sides of the hole structure c, surrounding the edge of the hole structure c and located on the periphery of the hole structure c.

[0099] Preferably, the free end of one traction band 5 is attached to a band sheet, and the free end of the other traction band 5 is attached to the attachment position of the upper band 2 of the two band sheets. When worn, the anti-dislocation elastic sheet 20 is located below the patella and is pulled upwards to lift the patella upwards to counteract the weight-bearing load on the knee, prevent patellar dislocation, and protect the patella and surrounding soft tissues.

The descriptions of these embodiments are merely for the purpose of helping to understand this invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
