Description

Technical Field

[0001] The utility model belongs to the technical field of sports protective gear, in particular to a knee pad support strip and a knee pad. Background Art

[0002] Knee pads are used to protect the human knee joint, providing warmth while reducing the risk of knee injury during exercise. Currently, knee pads on the market are typically woven, elastic, tubular structures that are pulled upward from the foot. However, these knee pads offer limited support, and during intense, competitive sports, the sides of the knee joint and the thigh near the knee joint are particularly vulnerable to injury.

[0003] To solve the above problems, the prior art provides support strips on the kneepad to improve the support capacity of the kneepad. For example, the patent application number is CN202120422806.5, and the name is a kneepad with high elastic support. The support strip in this patent includes a first elastomer and a second elastomer, and one end of the second elastomer is located in the middle of the first elastomer, so that the support strip is roughly in a "Y" shape. Among them, the other end of the second elastomer extends toward the back of the human thigh to support the human thigh, so that the thigh muscles are tightened toward the front, the muscles remain tight, and damage during impact is avoided or reduced.

[0004] When the above-mentioned knee pad is worn, the human knee bends repeatedly, and the second elastic body moves back and forth. The angle between the second elastic body and the first elastic body will change back and forth, and the upper part of the first elastic body will block the movement of the second elastic body, resulting in greater resistance when the knee is straightened. At the same time, the structure of the support bar is not conducive to force dispersion, resulting in limitations in the use of existing knee pad support bars. Utility Model Content

[0005] The purpose of the present utility model is to propose a knee pad support strip and a knee pad, and the structure of the support strip is improved so that the support strip has a larger deformation range and can adapt to different users. At the same time, it can avoid the problem of excessive resistance during the straightening of the human knee. In addition, the support strip of the present application is more conducive to force dispersion and is more comfortable to wear.

[0006] The utility model provides a knee support strip, comprising an elastic body of an integrated structure, wherein the elastic body comprises two arc-shaped segments and a connecting segment located between the two arc-shaped segments;

[0007] The connecting section is in an elongated structure and has two ends, one end of each arc segment is connected to the corresponding end, and the other end of each arc segment extends outwardly in a direction away from the connecting section;

[0008] Each arc segment spirally extends from one end toward the other end, and the two arc segments are respectively used to fit the thigh and calf of the human body.

[0011] The connecting section of the present application can adopt a straight plate structure or an arc structure. When in use, the connecting section can fit the side of the human knee joint in the vertical direction, or fit the side of the human knee joint in an inclined manner. The connecting section has two ends, and the two ends are respectively connected to the two arc sections. The two arc sections extend outward relative to each other, so that the two arc sections fit the human thigh and calf respectively during use, which means that the elastic main body of the one-piece structure composed of the two arc sections and the connecting section can fit the side of the human knee, calf and thigh respectively. Since the two arc sections are respectively connected to the ends of the connecting section, when the two arc sections bend with the human knee, there is no extra force away from the bent side of the knee to prevent the knee from straightening, thereby reducing the resistance during the bending and straightening of the knee, making the knee pad with this support strip more comfortable to wear.

[0012] At the same time, the arc setting direction of the two arc segments is a spiral setting, which means that during use, the support bar can fit the human thigh in the oblique upward direction and the posterior side of the thigh, and fit the human calf in the oblique downward direction and the posterior side of the calf, which can make the support bar more conducive to the dispersion of force during the bending process of the knee, making the knee pad equipped with the support bar of this application more comfortable to wear.

[0013] Moreover, the angle between the two arc sections and the connecting section can change during the bending of the human knee, which means that the overall deformation of the elastic body is larger, so that the support bar has a larger deformation range and can adapt to different users.

[0014] Furthermore, the connecting section is in a "〕" shape, and is composed of a vertical section and two inclined sections. Each inclined section is correspondingly connected to each arc section, and the elastic body is symmetrically arranged along the central axis perpendicular to the length direction of the vertical section.

[0015] Furthermore, the included angle between the inclined section and the vertical section is ∠a, and the included angle between the two inclined sections is ∠b, wherein ∠a=∠b / 2+90°.

[0016] Furthermore, at least one notch is formed on the connecting section, and the two arc-shaped sections can rotate toward the notch around a rotation axis point in the middle of the connecting section.

[0017] The present application also provides a knee pad, comprising at least one of the above-mentioned knee pad support strips, and also comprising a cylindrical elastic body; the knee pad support strip is located outside the elastic body, and the elastic body of the knee pad support strip is fixedly connected or detachably connected to the elastic body.

[0023] The elastic body of another knee pad support strip is overlapped and connected with the elastic body of any other knee pad support strip to form a reinforced support strip.

[0024] Furthermore, the elastic body and the elastic main body are detachably connected via at least four connecting pieces, wherein two connecting pieces are used to connect the connecting segment and the elastic body, and the other two connecting pieces are used to connect the other end of each arc segment and the elastic body respectively.

DETAILED DESCRIPTION

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

[0038] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0040] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention provides a knee brace support strip comprising an integrated elastic body 100. The elastic body 100 can be made of an elastic plastic, such as nylon or TPE, or can be a flat, linear structure formed by compressing a coil spring as is conventionally used, to provide the elastic body 100 with the ability to recover from deformation. This application primarily focuses on the overall structural design of the elastic body 100, so that it provides improved support for the knee brace and conforms to ergonomics.

[0041] The elastic body 100 of the present application is a strip-shaped structure as a whole. The elastic body 100 is made of elastic plastic. The elastic body 100 includes a connecting section 140 and two arc sections 110. The two arc sections 110 are located on the same side of the connecting section 140 and are respectively connected to the connecting section 140; one end of each arc section 110 is connected to the corresponding end of the connecting section 140, and the other end of each arc section 110 extends in a direction away from the connecting section 140, and the two arc sections 110 extend outward in opposite directions along the connecting section 140; the arc direction of each arc section 110 extends in a spiral from one end toward the other end.

[0042] The connecting section 140 of the present application can adopt a straight plate structure or an arc structure. When in use, the connecting section 140 fits the side of the human knee joint, and the connecting section 140 has two ends, and the two ends of the connecting section 140 are respectively connected to the two arc sections 110. The two arc sections 110 extend outward in opposite directions, so the two arc sections 110 fit the human thigh and calf respectively during use, which means that the elastic main body 100 of the one-piece structure composed of the two arc sections 110 and the connecting section 140 can fit the side of the human knee, calf and thigh respectively. Since the two arc sections 110 are respectively connected to the ends of the connecting section 140, when the two arc sections 110 bend with the human knee, there is no extra force away from the bent side of the knee to prevent the knee from straightening, thereby reducing the resistance during the bending and straightening of the knee, making the knee pad with this support bar more comfortable to wear.

[0043] At the same time, the arc setting direction of the two arc segments 110 is a spiral setting, which means that during use, the support bar can fit the human thigh in the oblique upward direction and the posterior side of the thigh, and fit the human calf in the oblique downward direction and the posterior side of the calf, which can make the support bar more conducive to the dispersion of force during the bending process of the knee, making the knee pad equipped with the support bar of this application more comfortable to wear.

[0044] In addition, the two arc segments 110 of the present application are located on the same side of the connecting segment 140, and the angle between the two arc segments 110 and the connecting segment 140 can change during the bending of the human knee, which means that the overall deformation of the elastic body 100 is larger, so that the support bar has a larger deformation range and can adapt to different users.

[0045] Furthermore, in order to make the elastic body 100 bear the force better, Figure 1 As shown, the connecting section 140 of the present application is in the shape of "〕", and the connecting section 140 is composed of a vertical section 130 and two inclined sections 120. Each inclined section 120 is smoothly connected to each arc section 110, and the elastic body 100 is symmetrically arranged along the central axis of the vertical section 130.

[0046] The elastic body 100 of the present application has a symmetrical structure, and the elastic body 100 is roughly in a "U" shape. Compared with the elastic body 100 with a "V" shape, the elastic body 100 of the present application can reduce the risk of breakage during the bending process of the connecting section 140, ensuring the long-term stable use of the elastic body 100; and the elastic body 100 of the present application is also more ergonomic during use.

[0047] At the same time, the elastic body 100 of the present application is also similar to the "〕" shape as a whole, so the two arc sections 110 of the elastic body 100 can have a larger deformation angle along the connecting section 140, so that the arc shape of the support strip set in the present application can adapt to the length of the knee pad pulled by different people.

[0048] Furthermore, the structure of the elastic body 100 of the present application can prevent the elastic body 200 from puncturing the knee pad, thus avoiding damage to the knee pad, regardless of whether the elastic body 100 is fixedly mounted on the knee pad or detachably connected.

[0049] Furthermore, in order to limit the scope of use of the elastic body 100 of the present application, as Figure 1 As shown, the angle between the inclined section 120 and the vertical section 130 of the present application is ∠a, and the angle between the two inclined sections 120 is ∠b, wherein ∠a=∠b / 2+90°.

[0050] It can be understood that when the elastic body 100 adopts a "V"-shaped structure, ∠b is equivalent to the angle between the two arc segments 110. When the two arc segments 110 bend and straighten with the knee, the bending angle is relatively small. However, the value of ∠a is significantly greater than ∠b. Therefore, when the elastic body 100 adopts the structure of the present application, the two arc segments 110 have a larger bending angle when bending and straightening with the knee. Therefore, the elastic body 100 of the present application has better deformation resistance and is less susceptible to damage than the elastic body 100 with a "V"-shaped structure.

[0051] Furthermore, during the knee bending process, the vertical section 130 of the connecting section 140 will inevitably deform. To reduce deformation resistance, the present application provides at least one notch 131 on the vertical section 130 of the connecting section 140. The notch 131 is located on the side where the arc section 110 is located. Figure 1 、 Figure 2 、 Figure 3 As shown, a plurality of notches 131 are provided on the vertical section 130 along its length direction. The shapes of the notches 131 can be the same or different so as to cope with different bending conditions and improve the comfort of use of the support bar.

[0052] The present application also provides a knee pad, such as Figure 4 、 Figure 5 As shown, it includes at least one of the above-mentioned knee pad support strips and a cylindrical elastic body 200; the knee pad support strip is located outside the elastic body 200, and the elastic body 100 of the knee pad support strip is fixedly connected or detachably connected to the elastic body 200.

[0053] The elastic body 200 is a knitted structure known in the prior art, exhibiting a certain degree of elasticity. One or more support bars can be provided on the elastic body 200. The elastic body 100 of the support bar is located on the vertical sidewalls of the elastic body 200 and connected to the elastic body 200. The elastic body 100 and the elastic body 200 can be fixedly connected using a conventional method. A layer of connecting fabric is covered on the outside of the elastic body 100. The connecting fabric and the elastic body 200 are knitted or glued together to securely connect the elastic body 100 and the elastic body 200, thereby forming a knee brace with support bars.

[0054] Of course, the elastic body 100 and the elastic body 200 can also be connected in a detachable manner, such as by Velcro, so that the elastic body 100 or the elastic body 200 can be replaced, which can reduce the replacement cost of the knee pad.

[0055] The knee pad of the present application has the support strip of the above structure, which is more comfortable than the knee pad provided with the support strip in the prior art. At the same time, it can be adapted to different wearers, and the knee pad has a better effect of dispersing the force during the knee bending process.

[0056] To further enhance the support strength of the kneepad, the present application connects two kneepad support strips to the elastic body 200. The two kneepad support strips are located on the left and right sides of the elastic body 200, and the elastic body 100 of each kneepad support strip is connected to the elastic body 200. By arranging the two elastic bodies 100 on the left and right sides of the elastic body 200, when the kneepad is worn, the two elastic bodies 100 will be located on the left and right sides of the knee to provide protection. Combined with the structure of the elastic body 100 of the present application, the knee can be supported from both sides to enhance the support strength.

[0057] Or, as Figure 6 As shown, the two elastic bodies 100 corresponding to the two knee brace support strips overlap and connect to form a reinforcement support strip, which is connected to the elastic body 200. The elastic bodies 100 can be connected by bonding, Velcro, magnetic attraction, or other methods. Two or more elastic bodies 100 can be superimposed to form a reinforcement support strip. The reinforcement support strip combines the support force of at least two elastic bodies 100. Even if the reinforcement support strip is placed on one side of the elastic body 200, it can still achieve the purpose of improving the support strength of the knee brace.

[0058] Of course, in order to further improve the supporting strength of the knee pad, at least three knee pad support strips are connected to the elastic body 200 of the present application, two of which are located on the left and right sides of the elastic body 200 respectively. The elastic body 100 of each knee pad support strip is connected to the elastic body 200, and the elastic body 100 of another knee pad support strip is overlapped and connected with the elastic body 100 of any other knee pad support strip to form a reinforced support strip.

[0059] It can be understood that an elastic body 100 is provided on each side of the elastic body 200, and multiple elastic bodies 100 can be stacked and fixed to the elastic body 200 to enhance the support strength of the entire knee brace. Furthermore, each elastic body 100 can be made of different materials to provide each elastic body 100 with various deformation resistance capabilities, allowing the knee brace of this application to be used in a variety of ways.

[0060] Furthermore, in order to achieve a detachable connection between the elastic body 200 and the elastic body 100, and at the same time satisfy the corresponding support effect of the elastic body 100 on the elastic body 200, the elastic body 200 and the elastic body 100 of the present application are detachably connected through at least four connecting members, two of which are used to connect the connecting section 140 and the elastic body 200, and the positions of each connecting member can be set at the end of the connecting section 140 or near the end of the connecting section 140. As shown in the figure, the two connecting members of the present application are respectively located on the two inclined sections 120 to connect the two inclined sections 120 and the elastic body 200; the other two connecting members are respectively used to connect the other end of each arc section 110 and the elastic body 200.

[0061] The four-point fixing method can achieve a stable connection between the elastic body 100 and the elastic body 200, so that the elastic body 100 can achieve a corresponding supporting effect during use.

[0062] The connecting members may have the same or different structures, as long as they ensure that the elastic body 100 and the elastic body 200 are securely connected under the action of the connecting members. In this application, the four connecting members are two first connecting members and two second connecting members; the first connecting members use a magnetic method to connect the two arc-shaped segments 110 of the elastic body 100 to the elastic body 200, and the second connecting members use a snap-fit ​​method to connect the connecting segment 140 of the elastic body 100 to the elastic body 200, thereby firmly connecting the entire elastic body 100 and the elastic body 200.

[0063] Specifically, such as Figure 4 、 Figure 5 As shown, the first connector includes two magnetically engaged connecting portions 112, one of which is fixed to the elastic body 200, and the other to the elastic body 100. The connecting portions 112 are magnets. The connecting portion 112 disposed on the elastic body 200 is embedded in the outer side of the elastic body 200, while the connecting portion 112 disposed on the arcuate segment 110 protrudes outward along the arcuate segment 110 and is secured with a magnet having opposite magnetic properties to the elastic body 200. The magnetic attachment of the two connecting portions 112 enables a detachable connection between the arcuate segment 110 and the elastic body 200.

[0064] Since each elastic body 100 can be overlapped and connected to other elastic bodies 100 as needed, a recessed portion 111 is provided on the elastic body 100 to facilitate the connection of the elastic bodies 100. The recessed portion 111 and the connecting portion 112 are respectively located on both sides of the arc segment 110 along its thickness direction. The recessed portion 111 is used to cooperate with the corresponding connecting portion 112 on other elastic bodies 100. Correspondingly, in order to enable the overlapping connection of each elastic body 100, attention should be paid to the magnetic properties of the corresponding connecting portion 112 so that each elastic body 100 can be overlapped and connected.

[0065] The second connecting member of the present application adopts a snap-fit ​​structure, with a socket provided on the elastic body 200 or the elastic body 100, and a straight-arm snap-fit, an L-shaped snap-fit, a circular snap-fit, etc. provided on another component. By utilizing the cooperation of the snap-fit ​​and the socket, a detachable connection between the elastic body 200 and the elastic body 100 can be achieved.

[0066] In the present application, in order to improve the connection stability between the elastic body 200 and the elastic body 100, two second connecting members are provided at corresponding positions on the connecting section 140, such as Figure 4 、 Figure 5 As shown, each second connecting member includes a snap-fit ​​protrusion 122 and a snap-fit ​​slot 210, and a telescopic card 211 is provided in the snap-fit ​​slot 210. The snap-fit ​​protrusion 122 is located in the snap-fit ​​slot 210 and is locked by the card 211. When the card 211 contracts, the snap-fit ​​protrusion 122 is unlocked from the snap-fit ​​slot 210; the snap-fit ​​slot 210 is opened on the elastic body 200, and the snap-fit ​​protrusion 122 is optionally set on the elastic body 100.

[0067] In this application, the overall structure of the second connector is designed based on the snap-fit ​​structure of the prior art "Apple Vision Pro Headband." A card 211 engages with a corresponding elastic member (not shown) and a snap-fit ​​protrusion 122 that enters the slot 210. The snap-fit ​​protrusion 122 is a bump structure, creating a recessed structure for the card 211 to engage with between the snap-fit ​​protrusion 122 and the connecting section 140. The cooperation between the card 211 and the snap-fit ​​protrusion 122 ensures a secure connection between the elastic body 100 and the elastic body 200. To remove the elastic body 100, pulling the pull cord 212 connected to the card 211 causes the card 211 to retract and separate from the snap-fit ​​protrusion 122, unlocking the snap-fit ​​protrusion 122 and the slot. At this point, the snap-fit ​​protrusion 122 can be separated from the slot 210, allowing the corresponding portion of the elastic body 100 to be removed from the elastic body 200. The recessed groove 121 facilitates the overlapping connection of the elastic bodies 100.

[0068] At the same time, a recessed groove 121 is also provided on the two inclined sections 120. The recessed groove 121 and the snap-fit ​​protrusion 122 are respectively located on both sides of the inclined section 120 along its thickness direction. The recessed groove 121 is used to cooperate with the corresponding snap-fit ​​protrusion 122 on the other elastic body 100.

[0069] The elastic body 100 and the elastic body 200 of the present application are detachably connected in two ways, which can not only ensure the firm connection between the elastic body 100 and the elastic body 200, but also reduce the difficulty of connection while maintaining a stable connection. In addition, the cooperation between the first connecting member and the second connecting member ensures that the elastic body 100 does not increase the overall thickness of the knee pad.

[0070] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above is only a specific implementation method of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the scope of the present invention should be included in the scope of protection of the present invention.
