Detailed Implementation

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0040] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0041] As shown in Figures 1-4, the present invention provides a lightweight quick-release support strip for connecting to the cylindrical body of a knee pad or elbow pad. The support strip includes a strip-shaped elastic body 1 and a connecting mechanism. The connecting mechanism includes a first connecting component 2 and a second connecting component 3 respectively disposed near the two ends of the elastic body 1. The first connecting component 2 includes a detachably connected connecting seat 23 and an elastic buckle 20. The connecting seat 23 is connected to the cylindrical body, and the elastic buckle 20 is connected to the elastic body 1. The second connecting component 3 includes a magnetically connected mounting seat 31 and a magnetic seat 32. The mounting seat 31 is connected to the cylindrical body, and the magnetic seat 32 is fixed to the elastic body 1.

[0042] Understandably, the cylindrical body is a woven cylindrical structure found in existing technologies, designed for easy wear by consumers. The connecting mechanism employs a combination of a first connecting component 2 and a second connecting component 3 to ensure an effective and secure connection between the elastic body 1 and the cylindrical body, while also allowing for quick disassembly for convenient use of the knee or elbow pads. Therefore, this application positions the first connecting component 2 and the second connecting component 3 close to both ends of the elastic body 1, effectively preventing connection instability caused by bending in the middle of the elastic body 1 during use.

[0043] Meanwhile, the first connecting component 2 uses a snap-fit ​​method to achieve a detachable connection between the elastic body 1 and the cylindrical body, while the second connecting component 3 uses a magnetic attraction method to achieve a detachable connection between the elastic body 1 and the cylindrical body. In use, after the elastic snap-fit ​​20 and the connecting seat 23 of the first connecting component 2 are unlocked, the elastic body 1 and the cylindrical body can be separated, which simplifies the connection method between the elastic body 1 and the cylindrical body, and enables quick disassembly of the elastic body 1 and the cylindrical body. This facilitates the replacement and disassembly of the elastic body 1, as well as the wearing and cleaning of knee or elbow pads.

[0044] Furthermore, the connecting seat 23 and the elastic buckle 20 of the first connecting component 2 can be connected to the elastic body 1 and the cylindrical body respectively. A detachable connection between the elastic body 1 and the cylindrical body can be achieved simply by detaching the connecting seat 23 and the elastic buckle 20. Of course, for ease of operation, this application fixes the connecting seat 23 to the cylindrical body and connects the elastic buckle 20 to the elastic body 1.

[0045] To facilitate the fixing of the mounting base 31, the connecting base 23 and the cylindrical body, the connecting base 23 and the mounting base 31 can be fixed to the cylindrical body by rivets 101, so as to achieve a modular cooperation of the cylindrical body, the connecting base 23 (or the mounting base 31) and the elastic body 1, avoiding the total loss if one part is damaged. If the elastic body 1 breaks, it can be replaced without scrapping the entire knee or elbow pad.

[0046] Because the elastic body 1 and the cylindrical body are detachably connected, the cylindrical body can be fixed with elastic bodies 1 of different support strengths. Users can choose elastic bodies 1 of different strengths according to their own weight and endurance, thus expanding the application range of knee or elbow pads.

[0047] In the first connecting component 2, the connecting seat 23 and the elastic buckle 20 are connected by a snap-fit. In this way, a snap-fit ​​groove can be set on the connecting seat 23. The elastic buckle 20 is a plastic elastic sheet. The elastic buckle 20 and the connecting seat 23 can be detachably connected by the snap-fit.

[0048] Of course, in another embodiment of this application, a connection method between the elastic buckle 20 and the connecting seat 23 is also disclosed. Specifically, the elastic buckle 20 includes a knob 21 and an elastic element 22. The knob 21 is slidably connected to the elastic body 1, and the elastic element 22 is located between the knob 21 and the elastic body 1. The connecting seat 23 is provided with a fixing protrusion 25, and the knob 21 slides and engages or disengages with the fixing protrusion 25. As shown in Figures 1, 2, and 5, the connecting seat 23 has a plate-like structure and is fixed to the cylindrical body by rivets 101. The connecting seat 23 is provided with a protruding fixing protrusion 25, which is similar to a "7" structure, so that the fixing protrusion 25 and the elastic buckle 20 can engage. To ensure that the elastic buckle 20 can be detachably connected to the fixing protrusion 25. As shown in Figures 1, 2, and 5, the elastic buckle 20 includes a knob 21 and an elastic element 22. The knob 21 includes a movable plate 211 with a plate-like structure and a fixed buckle 212, which resembles a "7" shape and is located below the movable plate 211. The fixed buckle 212 engages with the fixed protrusion 25, enabling the elastic buckle 20 to engage with the connecting seat 23. To facilitate the movement of the elastic buckle 20, an elastic element 22, which is a horizontally positioned spring, is provided between the knob 21 and the elastic body 1. In use, the user applies force to the movable plate 211, driving the movable plate 211 to move and forcing the elastic body to compress. At this time, the fixed buckle 212 and the fixed protrusion 25 separate, and an external force is applied to move the elastic body 1 away from the cylindrical body, thus separating one end of the elastic body 1 from the cylindrical body. When it is necessary to connect one end of the elastic body 1 to the cylindrical body, simply apply pressure to the elastic body 1 toward the cylindrical body while driving the moving plate 211 to move. Remove the external force on the moving plate 211, and the moving plate 211 will move under the action of the spring, driving the fixing buckle 212 to move and engage with the fixing protrusion 25, thus completing the connection between the elastic body 1 and the cylindrical body.

[0049] To facilitate the engagement of the dial 21 and the connecting seat 23, pressure is applied towards the connecting seat 23 (cylindrical body), allowing the moving plate 211 of the dial 21 to move automatically and engage with the fixed protrusion 25 under the action of the elastic element 22. In another embodiment of this application, the dial 21 is provided with a guide slope 2121, and the fixed protrusion 25 is provided with a wedge surface 251 that cooperates with the guide slope 2121. As shown in Figures 1, 2, and 5, the bottom sidewall of the fixing buckle 212 is provided with a guide slope 2121, and the top sidewall of the fixing protrusion 25 is provided with a inclined wedge surface 251. In use, when the guide slope 2121 of the fixing buckle 212 and the wedge surface 251 of the fixing protrusion 25 are in contact, the fixing buckle 212 (dial 21) is subjected to a pressing force towards the connecting seat 23, and the fixing buckle 212 moves horizontally under the action of the fixed protrusion 25.

[0050] To facilitate positioning and connection between the elastic buckle 20 and the connecting seat 23, in another embodiment of this application, the connecting seat 23 is further provided with a protruding positioning protrusion 24, and the elastic body 1 is provided with a positioning groove 111 that engages with the positioning protrusion 24. As shown in Figures 1 and 2, the connecting seat 23 is provided with a positioning protrusion 24, which is adjacent to the fixing protrusion 25. The elastic body 1 is provided with a positioning groove 111 with a through hole structure. In use, positioning is achieved by engaging the positioning groove 111 and the positioning protrusion 24. At this time, the fixing buckle 212 will be positioned with the fixing protrusion 25, which facilitates the connection between the fixing buckle 212 and the fixing protrusion 25.

[0051] The first connecting component 2 uses a snap-fit ​​method to connect one end of the elastic body 1 to the cylindrical body. This snap-fit ​​method ensures a stable connection between the elastic body 1 and the cylindrical body. To enable quick disconnection of the elastic body 1 and the cylindrical body, the second connecting component 3 of this application uses a magnetic attraction method to connect the other end of the elastic body 1 to the cylindrical body. To achieve the positioning and magnetic attraction of the mounting base 31 and the magnetic base 32, in another embodiment of this application, the mounting base 31 includes a mounting plate 311 and a mounting protrusion 312. The mounting plate 311 is fixed to the cylindrical body, and the mounting protrusion 312 protrudes away from the cylindrical body. At least one first magnetic attractor 313 is fixed on the mounting protrusion 312, and the first magnetic attractor 313 is magnetically connected to the magnetic base 32. As shown in Figures 1 and 2, the mounting plate 311 is fixed to the cylindrical body by rivets 101, and the mounting protrusion 312 protrudes outward from the cylindrical body. Each first magnetic attractor 313 is embedded and fixed on the mounting protrusion 312. The first magnetic element 313 is a powerful magnet, and the magnetic base 32 is provided with a magnet with the opposite magnetic force to the first magnetic element 313, or it can be made of a metal (such as iron) that can be magnetically attracted to the first magnetic element 313. Of course, the first magnetic element 313 can also be made of a metal material (such as iron) that can be magnetically attracted to a magnet, and the magnetic base 32 can also be provided with a powerful magnet to achieve magnetic attraction and fixation between the first magnetic element 313 and the magnetic base 32. In this application, the first magnetic element 313 is a powerful magnet that is injection molded into the mounting protrusion 312.

[0052] Furthermore, to facilitate the positioning and magnetic attraction of the magnetic base 32 and each of the first magnetic components 313, in another embodiment of this application, the magnetic base 32 has a groove-shaped structure. The magnetic base 32 is used to be engaged with the mounting protrusion 312. The magnetic base 32 is provided with at least one second magnetic component 321, and each second magnetic component 321 is used in conjunction with each of the first magnetic components 313. As shown in Figures 1 and 2, the magnetic base 32 is provided with two second magnetic components 321. The second magnetic components 321 are strong magnets, and the second magnetic components 321 are fixed to the elastic body 1 by in-mold injection molding.

[0053] To ensure better wear resistance of the elastic body 1, in another embodiment of this application, the elastic body 1 is made of plastic material, preferably a plastic material with excellent physical and chemical properties such as high wear resistance, high impact resistance, high chemical resistance, hydrolysis resistance, heat resistance, non-toxicity to the human body, and high toughness.

[0054] To ensure the elastic body 1 has a good elastic structure, in another embodiment of this application, the elastic body 1 has a strip-shaped structure that is narrow in the middle and wide at both ends. The elastic body 1 includes a first connecting segment 11, a strip-shaped bent segment 12, and a second connecting segment 13 connected in sequence. The first connecting segment 11 is connected to the elastic buckle 20, and the second connecting segment 13 is fixed to the magnetic base 32. As shown in Figures 1, 2, 3, 4, and 6, the bent segment 12 has an elastic structure, and the width of the bent segment 12 is smaller than that of the first connecting segment 11 and the second connecting segment 13, making the bent segment 12 easier to bend during use. Meanwhile, the first connecting segment 11 and the second connecting segment 13 facilitate the installation of the first connecting component 2 and the second connecting component 3, making the elastic body 1 with this structure more conducive to installation and use.

[0055] To increase the bending resistance of the elastic body 1, the structure of the bending segment 12 can be designed. In another embodiment of this application, the bending segment 12 has two opposing bending sidewalls, each with a plurality of slots 122. The slots 122 are spaced apart along the length of the bending sidewalls. As shown in Figure 6, the left and right sides of the bending segment 12 are the bending sidewalls. Therefore, a plurality of slots 122 are provided on the left and right sides of the bending segment 12. The arrangement of the slots 122 on the bending sidewalls makes the bending segment 12 resemble a wavy strip, thereby increasing the bending resistance of the bending segment. It has greater support strength than the conventional strip-shaped bending segment 12, making it suitable for other users.

[0056] Of course, to increase the bending resistance of the bent section 12, the bent section 12 can also have other structures. In another embodiment of this application, a protruding arc-shaped reinforcing part 121 is connected to the bent section 12, and the arc-shaped reinforcing part 121 extends along the length direction of the bent section 12. As shown in Figures 1, 2, and 3, the bent section 12 has a conventional smooth strip structure, and an arc-shaped reinforcing part 121 is provided at the upper part of the bent section 12. The arc-shaped reinforcing part 121 has a hollow arc-shaped plate structure. The arc-shaped reinforcing part 121 is used to increase the support strength of the bent section 12, so that the elastic body 1 can have different support strengths according to different structures, thereby increasing the application range of the support strip.

[0057] To facilitate a secure connection between the positioning protrusion 24 and the positioning groove 111, as shown in Figures 1 and 2, a retaining protrusion 103 can be provided circumferentially on the positioning protrusion 24, and a recessed groove 102 can be provided on the inner wall of the positioning groove 111. This reduces the gap between the positioning protrusion 24 and the positioning groove 111 during connection, ensuring a secure connection between the two. Similarly, a retaining protrusion 103 is provided circumferentially on the mounting protrusion 312, and a recessed groove 102 is provided on the inner wall of the magnetic base 32 to reduce the gap between the mounting protrusion 312 and the magnetic base 32 during connection, ensuring a secure connection between the two.

[0058] During use, if the support bar is bent at a large angle, it will deform in the direction perpendicular to the bending direction, reducing the support effect. If it deforms into the body, it will also press against the user area, causing discomfort. To reduce the impact of excessive bending angle of the support bar, in another embodiment of this application, the connecting mechanism further includes a third connecting component. The third connecting component is connected by magnetic attraction or snap-fit, and is used to connect the middle part of the elastic body 1 and the cylindrical body.

[0059] Understandably, the first connecting component 2, the second connecting component 3, and the third connecting component provide three-point positioning for the elastic body 1 of the support strip, thus connecting the elastic body 1 to the cylindrical body. Simultaneously, the third connecting component connects the middle part of the elastic body 1 to the cylindrical body. Since the middle part of the elastic body 1 is the main deformation area of ​​the support strip during use, the presence of the third connecting component prevents large displacement or deformation of the middle part of the elastic body 1 during bending, avoiding the problem of bending deformation hitting the usage area and allowing the support strip to better conform to the shape of the limb.

[0060] To achieve the connection between the elastic body 1 and the cylindrical body, the structure of the third connecting component can adopt the strong magnetic attraction connection method, the toggle buckle connection method described above in this application, or the rotation buckle connection, button buckle connection, buttonless buckle connection (designed with the buckle structure of the "Apple Vision Pro headband"), etc.

[0061] Specifically, as shown in Figures 7 and 8, the first connecting component 2, the second connecting component 3, and the third connecting component on the elastic body 1 all adopt a button-type snap-fit ​​connection. The button-type snap-fit ​​structure includes a locking block 125 and a snap-fit ​​member. The locking block 125 is fixed to the elastic body 1, and the snap-fit ​​member is fixed to the cylindrical body. The snap-fit ​​member typically adopts a telescopic locking tongue, which telescopically engages or disengages with the snap-fit ​​groove 126 on the locking block 125 to achieve a detachable connection between the elastic body 1 and the cylindrical body.

[0062] To further improve the adjustable support force of the support strip, the overall structure of the elastic body 1 in this application can also adopt the structure shown in Figures 7 and 8. The overall structure of the elastic body 1 still adopts a structure that is smaller in the middle and larger at both ends. The bending section 12 includes a wave section 120, a middle section 123 and a wave section 120 connected in sequence. The two wave sections 120 are connected to the first connecting section 11 and the second connecting section 13 respectively by a circular arc transition connection. The locking block 125 is fixed on the middle section 123, and the wave section 120 is composed of circular arc protrusions that are connected in sequence from the inside to the outside.

[0063] In actual production, the length of the wave segment 120 can be designed to vary depending on the length specifications of the support bar, or the bending radius (circular arc protrusion structure). However, it must be ensured that the wave segment 120 has at least two circular arc protrusion structures on the outer side of the support bar's bend and at least one complete circular arc protrusion structure on the inner side. The presence of the wave segment 120 contributes to the overall support force of the elastic body, increases the rebound effect of the support bar during use, and improves user comfort.

[0064] Furthermore, the lightweight quick-release support strip described in this invention can be used in protective gear such as knee pads and elbow pads.

[0065] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention should be included within the protection scope of the present invention.
