Description

Technical Field

[0001] This invention relates to the field of knee brace technology, and more specifically, to a knee brace for roller skating with cushioning and shock absorption function. Background Technology

[0002] Roller skating is highly entertaining, offering fun in terms of speed and technique. It can be practiced individually or in groups, making it popular with children for both casual leisure activities and small competitions among friends and classmates. However, beginners often fall while learning to roller skate. Since the knees are relatively vulnerable, knee braces are necessary to protect them. When a beginner falls, the plastic shell of the knee brace hits the ground directly, creating a reaction force. While this initial shock absorption by the plastic shell reduces injury, it still causes significant impact damage. Furthermore, if the fall is too forceful, the plastic shell may break, causing secondary injury to the knee. Therefore, we propose a knee brace with cushioning and shock absorption functions to better protect the user's knees. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a knee brace for roller skating with cushioning and shock absorption functions. This solves the problem that when beginners fall, the plastic shell of the knee brace directly impacts the ground, generating a reaction force. While the reaction force is initially cushioned by the plastic shell, it is directly transmitted to the beginner's knee. Although this reduces injury to beginners, it still causes significant impact damage to the knee. Furthermore, if the fall is too forceful, the plastic shell may break, causing secondary injury to the knee.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A knee brace for roller skating with cushioning and shock absorption function includes a knee brace sleeve, a protective shell installed at the front end of the knee brace sleeve, a shock absorption mechanism installed on the front surface of the protective shell, the shock absorption mechanism including grooves, the grooves being respectively disposed on the front surface of the protective shell and parallel to each other, a guide block being fixedly installed at the rear end inside the groove, and a connecting block being movably installed at the front end inside the groove, one end of the connecting block located inside the groove being connected to a U-shaped spring sheet, the two ends of the U-shaped spring sheet being respectively abutted to the guide block, and the front end of the connecting block being fixedly connected to a support plate.

[0006] A limiting strap is installed in the middle of the back side of the knee brace, and a cushioning pad is installed inside the back side of the knee brace, with the cushioning pad and the limiting strap being parallel to each other.

[0007] The knee brace has Velcro tabs on the top and bottom sides, respectively.

[0008] Preferably, a cloth bag is installed in the middle of the back side of the knee pad, and the cushioning pad is installed inside the cloth bag. The cushioning pad is made of a flexible material.

[0009] Preferably, the Velcro tabs and Velcro closures are sewn onto the upper and lower ends of the knee brace by needle and thread, and the Velcro tabs and Velcro closures correspond to each other.

[0010] Preferably, the side of the U-shaped spring near the buffer pad is fixedly connected to the V-shaped spring, the connection between the U-shaped spring and the V-shaped spring and the inclined surface of the guide block are in contact with each other, and the end of the V-shaped spring away from the guide block is in contact with the inner surface of the groove.

[0011] Preferably, positioning blocks are fixedly installed at both ends of the inside of the groove, and the end of the V-shaped spring piece away from the guide block is engaged with the positioning block.

[0012] Preferably, the guide block has a through-hole groove, and a pusher is fixedly installed on the side of the connecting block near the U-shaped spring. The rear end of the pusher is movably installed inside the groove, and a spring is installed between the pusher and the groove.

[0013] Preferably, the limiting band is made of an elastic material.

[0014] 1. In this invention, the fit between the U-shaped and V-shaped springs and the groove and guide block allows the support plate to slide along the surface of the guide block and groove immediately after a user falls, via the connecting block, to perform initial shock absorption. Simultaneously, the push frame moves inside the movable groove following the connecting block, compressing the spring for secondary shock absorption. Finally, the cushioning pad further cushions and absorbs shock to the user's knees, reducing the impact injury to the knees after a fall. Thus, through multiple shock absorption and cushioning measures, the damage to the user's knees is minimized, providing better protection.

[0015] 2. In this invention, a cushioning pad is used as the final layer of shock absorption and protection in the whole system, thereby minimizing the impact injury to the user's knees. It also allows the user's knees to fit better with the knee pads, so as not to hinder the user's roller skating. At the same time, if the user falls with too much force and damages the push frame and protective shell, the cushioning pad will block the debris generated when the push frame and protective shell are damaged, thereby preventing the debris from causing serious damage to the knees and providing better protection for the user.

[0016] 3. In this invention, the elasticity of the limiting band, combined with the Velcro tabs, allows for the wearing of the garment on legs and knees of different thicknesses, making it more convenient for various users and greatly improving the overall usability. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 5As shown, a roller skating knee pad with cushioning and shock absorption function includes a knee pad 1, a protective shell 4 installed at the front end of the knee pad 1, a shock absorption mechanism 5 installed on the front surface of the protective shell 4, the shock absorption mechanism 5 includes a groove 501, the grooves 501 are respectively provided on the front surface of the protective shell 4 and are parallel to each other, a guide block 502 is fixedly installed at the rear end inside the groove 501, and a connecting block 509 is movably installed at the front end inside the groove 501. One end of the connecting block 509 located inside the groove 501 is connected to a U-shaped spring 504, and both ends of the U-shaped spring 504 are respectively attached to the guide block 502. The front end of the connecting block 509 is fixedly connected to a support plate 510.

[0025] A limiting strap 6 is installed in the middle of the back side of the knee pad 1, and a cushioning pad 7 is installed inside the back side of the knee pad 1, with the cushioning pad 7 and the limiting strap 6 being parallel to each other.

[0026] The upper and lower sides of the knee pad 1 are respectively equipped with Velcro 2 and Velcro 3.

[0027] like Figure 3 and Figure 4 As shown, in the specific setup, a cloth bag 8 is installed in the middle of the back side of the knee pad 1, and a cushioning pad 7 is installed inside the cloth bag 8. The cushioning pad 7 is made of flexible material.

[0028] The cushioning pad 7 is made of flexible silicone and other materials, which allows it to fit snugly against the user's knees, thus not hindering the user's roller skating. At the same time, the cushioning pad 7 reduces the impact force on the user's knees after a fall, reducing the risk of knee injury.

[0029] By installing the cushioning pad 7 inside the cloth bag 8, the cushioning pad 7 and the knee pad 1 are integrated. Therefore, when the user falls, the shock absorption mechanism 5 will first provide multiple shock absorption and cushioning for the impact force generated when falling. Then, the impact force will be further absorbed by the cushioning pad 7, resulting in less impact on the knee after the user falls, less chance of injury, and better protection for the user.

[0030] like Figure 1 and Figure 3 As shown, in the specific setup, both the Velcro tab 2 and the Velcro tab 3 are sewn onto the upper and lower ends of the knee brace 1 with needle and thread, and the Velcro tab 2 and the Velcro tab 3 correspond to each other.

[0031] By sewing the Velcro 2 and Velcro 3 onto the knee brace 1 with needle and thread, the Velcro 2 and Velcro 3 are integrated with the knee brace 1, thus preventing the Velcro 2 and Velcro 3 from separating from the knee brace 1 due to the force generated when the user falls, which would cause the knee brace 1 to be unable to stably protect the knee.

[0032] Meanwhile, after the user installs the knee brace 1 between the knee brace 1 and the limiting strap 6, the adhesive connection between the Velcro 2 and the Velcro 3 makes the knee brace 1 and the knee form a whole, thus preventing the knee brace 1 from falling off during the user's roller skating.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in the specific configuration, the side of the U-shaped spring 504 near the buffer pad 7 is fixedly connected to the V-shaped spring 505. The connection between the U-shaped spring 504 and the V-shaped spring 505 and the inclined surface of the guide block 502 are in contact with each other. The end of the V-shaped spring 505 away from the guide block 502 is in contact with the inner surface of the groove 501. The two ends of the groove 501 are fixedly installed with positioning blocks 503. The end of the V-shaped spring 505 away from the guide block 502 is engaged with the positioning blocks 503. The guide block 502 is provided with a movable groove 506 through it. The side of the connecting block 509 near the U-shaped spring 504 is fixedly installed with a pusher 507. The rear end of the pusher 507 is movably installed inside the movable groove 506. A spring 508 is installed between the pusher 507 and the movable groove 506.

[0034] When a user falls, multiple support plates 510 and connecting blocks 509 can protect the knees from various angles depending on the direction of the fall, thus providing better protection for the user's knees. When the support plates 510 come into contact with the ground, as the knee continues to fall, the support plates 510 will drive the connecting blocks 509 to push the U-shaped springs 504 and V-shaped springs 505, allowing the U-shaped springs 504 and V-shaped springs 505 to slide along the surfaces of the guide blocks 502 and grooves 501, distributing the impact force to the entire protective shell 4 and knee pad 1 for initial cushioning, preventing damage to the knees due to excessive impact force at one end. At the same time, the pusher 507 will compress the springs 508 inside the movable groove 506 for secondary shock absorption and cushioning. Finally, the cushioning pad 7 will provide a third round of cushioning and shock absorption to the impact force on the knees, preventing serious knee injuries after a fall and providing better protection for the user.

[0035] Meanwhile, when the user gets up, the U-shaped spring 504, V-shaped spring 505 and spring 508 will automatically reset the support plate 510 and connecting block 509 through elastic force, waiting for the next use.

[0036] like Figure 3 As shown, in a specific configuration, the limiting band 6 is made of an elastic material.

[0037] The limiting strap 6 is made of elastic leather and the like, so that it can better fit the knee pad 1 according to the thickness of the user's leg, so that it can form a whole with the user's leg, thus not hindering the user's roller skating, but also providing more stable protection for the user's knee.

[0038] The working principle of this type of knee pad for roller skating with cushioning and shock absorption function:

[0039] In use, when a user falls, multiple support plates 510 and connecting blocks 509 protect the knees from various angles depending on the direction of the fall, thus providing better protection for the user's knees. When the support plates 510 come into contact with the ground, as the knee continues to fall, the support plates 510 drive the connecting blocks 509 to push the U-shaped springs 504 and V-shaped springs 505, causing them to slide along the surfaces of the guide block 502 and the groove 501, distributing the impact force across the entire protective shell 4 and knee pad 1 for initial cushioning, preventing damage to the knee from excessive impact at one end. Simultaneously, the pusher 507 compresses the spring 508 inside the movable groove 506 for secondary shock absorption and cushioning. Finally, the cushioning pad 7 provides a third layer of cushioning and shock absorption to the knee, preventing serious knee injuries after a fall and providing better protection for the user.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
