Description

Technical Field

[0001] The present invention relates to the technical field of knee joint protectors, in particular to a wear-resistant seamless glue-dotted knee joint protector. Background Art

[0002] With the development of biomedical engineering, people have not only gradually realized the importance of exercise, but also paid more attention to how to exercise correctly. In order to improve athletic performance and protect joints, athletes often use strapping protective gear, such as special straps wrapped around the knee joint (usually called knee joint protectors). Knee joint protectors are used to fix the patella and act as a buffer when the patella is subjected to force, so as to reduce damage to the patella during exercise.

[0003] Traditional knee braces use a sewing process, so the inner surface of the brace has stitches. During exercise, these stitches will rub against the skin of the wearer, especially when the wearer's legs are in a state of high-frequency contraction for a long time (such as long-distance running), the skin will be worn by the stitches. To solve the above wear problem, the existing technology introduces a seamless glue point process to replace the original sewing process. The glue point uses glue to splice multiple pieces of fabric for the brace. Compared with stitches, the glue point not only has a larger surface area, but also has a lower elastic modulus, which can reduce the local pressure on the wearer's legs and thus reduce friction.

[0004] The use of a seamless dispensing process avoids direct contact between the stitches and the user's skin, thereby preventing the knee brace from abrading the user's skin. However, this ability to avoid abrasion is limited, especially in high-temperature exercise environments. The reasons are as follows: As the user's exercise intensity increases or the exercise time increases, the body will produce a large amount of sweat. The knee brace not only absorbs sweat, thereby increasing friction with the skin, but also prevents sweat from being discharged from the inside of the brace, causing the wrapped skin to soften and become sensitive. Under the combination of the above two factors, the skin will still be abraded by the knee brace.

[0005] Therefore, an anti-wear seamless glue-dispensing knee joint protector is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a wear-resistant seamless glue-dot knee joint protector, which solves the problem that the knee joint protector will wear the skin when absorbing a large amount of sweat. By arranging multiple glue points on the inner surface of the knee joint protector and changing the shape and arrangement of each glue point, the purpose of promoting sweating of the knee joint protector is achieved, reducing the accumulation of sweat, and thereby reducing its wear on the user's skin.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A wear-resistant, seamless, glue-dotted knee brace comprising an F zone, an L zone, a B zone, an R zone, and ribbing, wherein the B zone is located in the center of the brace, the L zone and the R zone are connected to the left and right sides of the B zone, respectively, the F zone comprises an LF zone and an RF zone, the LF zone is connected to the left side of the L zone, the RF zone is connected to the right side of the R zone, the ribbing is connected above and below the LF zone, the L zone, the B zone, the R zone, the LF zone, and the R zone, glue dots are arranged on each of the B zone, the L zone, the R zone, the LF zone, and the RF zone, and the glue dots are arranged obliquely within the L zone, the R zone, the LF zone, and the RF zone, and the patellar groove is provided within the LF zone and the RF zone.

[0009] The B zone faces the back of the knee, the patellar groove surrounds the patella, and the obliquely arranged glue points inside the L zone, R zone, LF zone and RF zone guide the sweat inside the protective gear to the B zone, and the B zone vibrates as the knee joint is straightened.

[0010] The distribution of sweat glands in the human body is uneven. The sweat glands are denser in the back of the thigh and popliteal fossa (behind the knee). Therefore, during exercise, more sweat will accumulate on the back of the knee brace.

[0011] Preferably, the B region includes B warp yarns and B weft yarns, the L region, R region, LF region and RF region all include bias warp yarns and bias weft yarns, and the fiber gap formed by the B warp yarns and B weft yarns is larger than the fiber gap formed by the bias warp yarns and bias weft yarns;

[0012] In the above scheme, the fiber gap formed by the B warp yarn and the B weft yarn is larger than the fiber gap formed by the bias warp yarn and the bias weft yarn, thereby making the permeability of the B area stronger and making it easier for sweat in the popliteal fossa to be discharged; and the leg muscles (such as the hamstring machine) are concentrated on the back of the leg, and the muscle contraction process will release a lot of heat, and the large gap between the B warp yarn and the B weft yarn makes it easier to discharge the heat accumulated on the back of the leg; as for the front part of the knee (i.e., the area around the patella), as the windward side, there are fewer muscles, so the heat generated during exercise is limited, and it will be quickly lost under the influence of wind. Therefore, the gap between the bias warp yarn and the bias weft yarn is made smaller, so as to effectively preserve the heat on the front of the knee and improve athletic performance.

[0013] Preferably, the B warp yarns and B weft yarns are parallel to the up-down direction and the left-right direction, respectively; the angles between the diagonal warp yarns and the diagonal weft yarns and the up-down direction or the left-right direction are acute angles; and the elastic modulus of the diagonal warp yarns and the diagonal weft yarns are higher than that of the B weft yarns;

[0014] Through the above scheme, the B weft yarn is easy to deform, and when wearing the knee brace, it is convenient for the user to stretch the knee brace in the left and right directions so that the patellar groove is aligned with the patella, thereby fixing the patella. At the same time, the stretching of the B weft yarn further increases the fiber gap formed by it and the B warp yarn, thereby enhancing the above-mentioned heat dissipation and perspiration effects; and the inclined arrangement of the oblique warp yarn and the oblique weft yarn can decompose the stress of the B weft yarn, thereby reducing its own deformation, thereby weakening the increase in the fiber gap formed by them, thereby maintaining the windproof and heat-insulating effect on the front side of the knee joint.

[0015] Preferably, the elastic modulus of the B weft yarn is smaller than the elastic modulus of the B warp yarn;

[0016] Through the above scheme, the deformation ability of area B in the up-down direction is made weaker than that in the left-right direction, so that area B emits high-frequency vibrations during human movement, thereby quickly draining sweat from the back of the knee joint.

[0017] The conventional adhesive dots are generally circular in structure and uniformly spaced. Their purpose is simply to act as a buffer between the skin and the knee joint fabric, thereby preventing wear and tear on the skin caused by the protective gear. Although the adhesive dots are made of soft material and can provide excellent cushioning, dynamic friction between the leg and the protective gear is inevitable during exercise, especially in the vertical direction. As the leg flexes and extends, slight relative displacement between the skin and the protective gear always occurs.

[0018] Preferably, the glue points include sweat-guiding points and sweat-dissipating points, the sweat-guiding points are distributed on the L area, the R area, the LF area and the RF area, and the sweat-dissipating points are distributed on the B area. The sweat-guiding points are arranged in an elliptical structure, and the long axis of the sweat-guiding points is inclined to the left and right directions, and the long axis vertex of the sweat-guiding points close to the B area is downward;

[0019] In the above scheme, the sweat-guiding points with an inclined setting and an elliptical structure, on the one hand, guide the sweat to area B and discharge it to the outside from area B, so as to avoid the accumulation of sweat in the protective gear fabric and the softening of the skin by sweat, thereby reducing the possibility of the skin being worn by the protective gear; on the other hand, the dynamic friction between the knee joint protector and the user's skin in the vertical direction is reduced, and the static friction between the knee joint protector and the user's skin in the horizontal direction is increased, thereby weakening the wear effect of the knee joint protector on the user's skin and making the protective gear more stable to wear.

[0020] Preferably, the sweat-discharging points are arranged in a circular structure, and the spacing between the sweat-discharging points is greater than the spacing between the sweat-conducting points;

[0021] In the above scheme, the sweat-guiding points are set as a circular structure with large spacing, which reduces the obstruction of the fiber gaps on the B side in terms of both area and number, so as to facilitate the sweat-guiding and heat dissipation effects of the B side; and the small spacing between the sweat-guiding points makes the L zone, R zone, LF zone and RF zone evenly stressed, so as to reduce the pressure and thus improve the wearer's comfort; at the same time, it also reduces the friction in the up and down and left and right directions, so as to avoid wear on the user's skin during exercise and when the protective gear is tightened.

[0022] In existing knee braces, the patellar groove is mostly circular. However, when wearing the brace, the user will pull the brace left and right to adjust the tightness. During this process, the horizontal diameter of the circular patellar groove is elongated, and the vertical diameter is correspondingly reduced. As a result, after the brace is fixed, the patellar groove does not fully fit the patella.

[0023] Preferably, the patellar groove is configured to be elliptical, and the long axis of the patellar groove is parallel to the up-down direction;

[0024] Through the above solution, the patellar groove can completely fit the patella, thereby improving the fixation effect of the patella and the comfort of the wearer.

[0025] Preferably, the lengths of the long axis and the short axis of the patellar groove in the RF region are respectively smaller than the lengths of the long axis and the short axis of the patellar groove in the LF region;

[0026] Through the above solution, after the knee brace is worn, the patellar groove in the RF area is in front of the patellar groove in the LF area, thereby forming a double fixation of the patella from back to front, thereby enhancing the protection of the wearer's patella.

[0027] Preferably, the rear surface of the LF region is installed with a first fleece-surface Velcro and a second fleece-surface Velcro, and the first fleece-surface Velcro and the second fleece-surface Velcro are respectively located on the left and right sides of the patellar groove of the LF region, and the front surface of the RF region is installed with a first thorn-surface Velcro and a second thorn-surface Velcro, and the first thorn-surface Velcro and the second thorn-surface Velcro are respectively located on the right and left sides of the patellar groove of the RF region, and the first thorn-surface Velcro and the second thorn-surface Velcro are respectively attached to the first fleece-surface Velcro and the second fleece-surface Velcro, and the lengths of the first fleece-surface Velcro and the second fleece-surface Velcro along the left-right direction are respectively greater than the lengths of the first thorn-surface Velcro and the second thorn-surface Velcro along the left-right direction;

[0028] In the above scheme, the knee joint protector is fixed to the user's knee joint by fitting the first fleece-side Velcro and the second fleece-side Velcro with the first thorn-side Velcro and the second thorn-side Velcro respectively, and the relevant installation method and shape design avoid the contact between the Velcro and the wearer's skin, thereby avoiding the wear of the Velcro on the skin.

[0029] Preferably, the ribs on the top include, from left to right, a left expansion section, an extension section, and a right expansion section. The extension section is located above region B, and the lines of the extension section are parallel to the up-down direction. The lines of the left expansion section and the right expansion section are both inclined to the up-down direction, and the lower ends of the lines of the left expansion section and the right expansion section are inclined toward the extension section.

[0030] In the above scheme, the left expansion section and the right expansion section use their own inclined lines to guide the sweat flowing from the upper leg to the knee joint protector to area B, thereby allowing the sweat to be discharged from area B; while the extension section uses its own vertical lines to adapt to the stretching of area B in the left and right directions when worn.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention divides the knee joint supporter into multiple zones. The B zone located at the back of the knee joint is designed with large fiber gaps to accelerate perspiration and heat dissipation from the back of the knee joint. The LF zone and RF zone located at the front of the knee joint are designed with small fiber gaps to improve the thermal insulation effect of the front of the knee joint and reduce sweat discharge. In addition, inclined glue points are provided on the LF zone and RF zone to guide sweat from the front of the supporter to the back. When the B zone vibrates with the wearer's leg flexion and extension, the sweat is shaken off to the back of the body to separate it from the forward moving body.

[0033] 2. The present invention arranges the B warp yarn and B weft yarn on the B zone in the vertical direction and the left-right direction, respectively, and makes the elastic modulus of the B weft yarn smaller than that of the B warp yarn, so that the B zone can maintain excellent deformation ability in the left-right direction while remaining tight in the vertical direction, thereby facilitating stretching and adjustment during the wearing of the protective gear, and can generate high-frequency jitter during the flexion and extension of the wearer's leg to shake off sweat accumulated on the back of the knee joint to the outside of the protective gear; and the elastic modulus of the B weft yarn is lower than the elastic modulus of the bias warp yarn and the bias weft yarn, respectively, to avoid an increase in the limit gap between the LF zone and the RF zone during the stretching and adjustment process, thereby maintaining the heat preservation of the front of the knee joint and reducing sweat discharge.

[0034] 3. The present invention arranges the glue points on the LF and RF zones into an inclined elliptical structure, thereby directing sweat from the front of the knee joint to zone B. This allows the sweat to be better discharged to the outside while reducing the dynamic friction between the wearer's skin and the knee joint protector in the vertical direction and increasing the static friction between the wearer's skin and the protector in the horizontal direction, thereby reducing the possibility of skin wear by the protector while making the protector more stable when worn on the leg. In addition, the inclined patterns of the left and right expansion sections of the upper ribbing can also direct sweat left on the upper leg to zone B, thereby further reducing the amount of sweat in the fabric on the front and left and right sides of the protector, further reducing the possibility of the protector abrading the wearer's skin.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figures 1 to 8 The present invention provides a wear-resistant seamless glue-dispensing knee joint protector, and the technical solution is as follows:

[0046] A wear-resistant, seamless, glue-dispensing knee brace comprises an F zone 1, an L zone 2, a B zone 3, an R zone 4, and ribbing 5. The B zone 3 is located in the center of the brace, the L zone 2 and the R zone 4 are connected to the left and right sides of the B zone 3, respectively. The F zone 1 comprises an LF zone 11 and an RF zone 12. The LF zone 11 is connected to the left side of the L zone 2, and the RF zone 12 is connected to the right side of the R zone 4. The ribbing 5 is connected above and below the LF zone 11, the L zone 2, the B zone 3, the R zone 4, the LF zone 11, and the RF zone 12. Glue points 6 are arranged on each of the B zone 3, the L zone 2, the R zone 4, the LF zone 11, and the RF zone 12. The glue points 6 inside the L zone 2, the R zone 4, the LF zone 11, and the RF zone 12 are arranged obliquely. Patellar grooves 7 are provided inside the LF zone 11 and the RF zone 12. Glue-dispensing is used for splicing different areas of the knee brace.

[0047] Zone B 3 faces the back of the knee, and the patellar groove 7 surrounds the patella. The obliquely arranged glue points 6 inside the L zone 2, R zone 4, LF zone 11 and RF zone 12 guide the sweat inside the protective gear to zone B 3. Zone B 3 vibrates as the knee joint is straightened.

[0048] As an embodiment of the present invention, refer to Figures 1 to 4 , Zone B 3 includes B warp yarn 31 and B weft yarn 32, Zone L 2, Zone R 4, Zone LF 11 and Zone RF 12 all include oblique warp yarn 21 and oblique weft yarn 22, and the fiber gap formed by the B warp yarn 31 and the B weft yarn 32 is larger than the fiber gap formed by the oblique warp yarn 21 and the oblique weft yarn 22.

[0049] As an embodiment of the present invention, refer to Figure 3 and Figure 4 , the B warp yarn 31 and the B weft yarn 32 are parallel to the up-down direction and the left-right direction respectively, the angles between the oblique warp yarn 21 and the oblique weft yarn 22 and the up-down direction or the left-right direction are both acute angles, and the elastic moduli of the oblique warp yarn 21 and the oblique weft yarn 22 are both higher than the elastic modulus of the B weft yarn 32; the combination of the B warp yarn 31 and the B weft yarn 32 is the same as the combination of the oblique warp yarn 21 and the oblique weft yarn 22. When the fabric formed by the two is spliced, the B warp yarn 31 of the B area 3 is parallel to the up-down direction or the B weft yarn 32 is parallel to the left-right direction, and the oblique warp yarn 21 or the oblique weft yarn 22 of the L area 2, the R area 4, the LF area 11 and the RF area 12 are tilted in the up-down direction or the left-right direction.

[0050] As an embodiment of the present invention, refer to Figure 3 , the elastic modulus of the B weft yarn 32 is smaller than the elastic modulus of the B warp yarn 31; during running, the athlete's legs will continuously flex and extend around the knees. When the legs are straightened and kicked back, the B warp yarn 31 in zone B 3 will be stretched in the up and down directions. The deformation ability of the B warp yarn 31 is limited (the deformation amplitude is small). In order to consume the energy generated by the stretching, it will vibrate at a high frequency, thereby expelling the sweat from the back of the knee joint to the outside.

[0051] As an embodiment of the present invention, refer to Figure 2 The glue point 6 includes a sweat-guiding point 61 and a sweat-dissipating point 62. The sweat-guiding point 61 is distributed on the L area 2, the R area 4, the LF area 11 and the RF area 12. The sweat-dissipating point 62 is distributed on the B area 3. The sweat-guiding point 61 is set to an elliptical structure, and the long axis of the sweat-guiding point 61 is inclined to the left and right direction, and the long axis vertex of the sweat-guiding point 61 close to the B area 3 is downward;

[0052] The force for the relative displacement between the knee joint and the protective gear is provided by the actively moving knee joint. Therefore, during the up-down relative displacement, the knee and the sweat-guiding point 61 will be closer in the up-down direction, and during the left-right displacement, the knee and the sweat-guiding point 61 will be closer in the left-right direction. As the sweat-guiding point 61 has an elliptical structure, the length of the major axis is greater than the minor axis, thereby reducing the contact area during the up-down relative displacement, and making the contact area larger when there is a trend of left-right relative displacement, thereby reducing the dynamic friction of the up-down relative displacement and increasing the static friction of the left-right relative displacement.

[0053] As an embodiment of the present invention, refer to Figure 2 The sweating points 62 are set to a circular structure, and the spacing between the sweating points 62 is greater than the spacing between the sweat guiding points 61; the sweating points 62 and the sweat guiding points 61 are processed using a dispensing machine, and different process parameters are set for the elliptical structure and the circular structure, and different point spacings are controlled.

[0054] As an embodiment of the present invention, refer to Figure 2 The patellar groove 7 is set to be an ellipse, and the long axis of the patellar groove 7 is parallel to the up and down direction. The lengths of the long axis and the short axis of the patellar groove 7 on the RF area 12 are respectively smaller than the lengths of the long axis and the short axis of the patellar groove 7 on the LF area 11; the protective gear is tightened in the left and right directions, but lacks adjustment in the up and down directions. Therefore, the patellar groove 7 is arranged in an ellipse to leave room for adjustment in the left and right directions, and a jelly strip is set on the patellar groove 7 to prevent the patellar groove 7 from causing indentations on the knee joint.

[0055] As an embodiment of the present invention, refer to Figure 2 、 Figure 5 and 8The back surface of the LF area 11 is installed with a first fleece-surface Velcro 111 and a second fleece-surface Velcro 112, and the first fleece-surface Velcro 111 and the second fleece-surface Velcro 112 are respectively located on the left and right sides of the patellar groove 7 of the LF area 11, and the front surface of the RF area 12 is installed with a first thorn-surface Velcro 121 and a second thorn-surface Velcro 122, and the first thorn-surface Velcro 121 and the second thorn-surface Velcro 122 are respectively located on the right and left sides of the patellar groove 7 of the RF area 12, and the first thorn-surface Velcro 121 and the second thorn-surface Velcro 122 are respectively attached to the first fleece-surface Velcro 111 and the second fleece-surface Velcro 112, and the lengths of the first fleece-surface Velcro 111 and the second fleece-surface Velcro 112 along the left and right directions are respectively greater than the lengths of the first thorn-surface Velcro 121 and the second thorn-surface Velcro along the left and right directions;

[0056] When wearing the knee protector, first stick the B area 3 to the back of the knee joint, then fold the LF area 11 toward the front of the knee joint, and align the patellar groove 7 on the LF area 11 with the patella, and then fold the RF area 12 toward the front of the knee joint so that the first thorn-surface Velcro 121 and the second thorn-surface Velcro 122 respectively fit the first fleece-surface Velcro 111 and the second fleece-surface Velcro 112, thereby completing the fixation of the protector on the wearer's leg.

[0057] As an embodiment of the present invention, refer to Figure 6 and Figure 7 The upper rib 5 includes a left expansion section 51, an extension section 52 and a right expansion section 53 from left to right. The extension section 52 is located above the B area 3, and the grain of the extension section 52 is parallel to the up-down direction. The grains of the left expansion section 51 and the right expansion section 53 are both inclined to the up-down direction, and the lower ends of the grains of the left expansion section 51 and the right expansion section 53 are biased toward the extension section 52; the left expansion section 51, the right expansion section 53 and the extension section 52 are cut from the same piece of cloth, and after cutting, cloths with similar shapes but different grain directions are obtained, and after splicing and combination, they form the rib 5.

[0058] Specifically, to ensure that zone B 3 has excellent perspiration and heat dissipation capabilities, the interfiber gaps formed by the B warp yarns 31 and the B weft yarns 32 are larger than the interfiber gaps formed by the bias warp yarns 21 and the bias weft yarns 22. This increases the permeability of zone B 3, thereby improving perspiration and heat dissipation capabilities. At the same time, the permeability of the LF zone 11 and the RF zone 12 is reduced, thereby improving thermal insulation capabilities and reducing sweat discharge.

[0059] In order to allow area B 3 to vibrate with the flexion and extension of the wearer's legs, thereby separating sweat, the elastic modulus of the B weft yarn 32 is made smaller than the elastic modulus of the B warp yarn 31. Consequently, the deformation ability of area B 3 in the vertical direction is weaker than that in the horizontal direction. When the wearer's legs are straightened, area B 3 is tightened in the vertical direction, thereby generating high-frequency vibration.

[0060] In order to ensure that the knee brace has sufficient deformation ability in the left-right direction when worn, so that the patellar groove 7 is directly opposite the patella, the B warp yarn 31 and the B weft yarn 32 are arranged in the up-down direction and the left-right direction respectively; and the elastic modulus of the B weft yarn 32 is lower than the elastic modulus of the bias warp yarn 21 and the bias weft yarn 22, so that the B weft yarn 32 is easy to deform, thereby facilitating the user to stretch the knee brace in the left-right direction when wearing it;

[0061] To increase the interfiber gaps in zone B 3 due to stretching while maintaining the gaps between the diagonal warp yarns 21 and diagonal weft yarns 22, thereby maintaining the thermal insulation capabilities of zones LF 11 and RF 12, the angles between the diagonal warp yarns 21 and diagonal weft yarns 22 and the vertical or horizontal directions are made acute. This decomposes the stress of the B weft yarn 32, thereby reducing its own deformation and weakening the increase in the interfiber gaps formed by them, thereby maintaining the windproof and thermal insulation effect on the front of the knee joint.

[0062] In order to guide the sweat on the front side of the knee joint to the B zone 3, the sweat guide point 62 is set to an inclined elliptical structure, and the long axis of the sweat guide point 61 is tilted in the left and right direction, and the long axis vertex of the sweat guide point 61 close to the B zone 3 is located below another long axis fixed point;

[0063] In order to prevent the perspiration points 62 on the B area 3 from hindering the perspiration and heat dissipation functions of the B area 3, the perspiration points 62 are arranged in a circular structure with large spacing. In terms of both area and number, the perspiration points 62 reduce the obstruction of the fiber gaps on the B surface, thereby facilitating the perspiration and heat dissipation effects of the B surface.

[0064] In order to make the patellar groove 7 fit the patella completely, the patellar groove 7 is set to be oval, and the long axis of the patellar groove 7 is parallel to the vertical direction. Then, when the patellar groove 7 is stretched left and right, resulting in a decrease in the vertical direction, the long axis of the oval structure can compensate.

[0065] In order to strengthen the fixation of the knee brace on the patella and improve the wearer's athletic performance, the lengths of the long axis and short axis of the patellar groove 7 on the RF zone 12 are respectively smaller than the lengths of the long axis and short axis of the patellar groove 7 on the LF zone 11. When the knee brace is worn, the patellar groove 7 in the RF zone 12 is in front of the patellar groove 7 in the LF zone 11, thereby forming a double fixation of the patella from back to front, thereby enhancing the protection of the wearer's patella.

[0066] In order to collect the sweat flowing down the upper leg into zone B 3, so as to further reduce the amount of sweat in the knee joint protector and thus further reduce the possibility of the skin being worn by the protector, the lines of the left expansion section 51 and the right expansion section 53 are both inclined, and the lower ends of the lines of the left expansion section 51 and the right expansion section 53 are biased toward the extension section 52.

[0067] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
