Description

Technical Field

[0001] The present invention relates to the technical field of joint assistive devices, and in particular to an assistive device for joint care of the elderly. Background Art

[0002] With the aging of the population, knee pain and joint instability caused by joint degeneration, arthritis and other problems are becoming increasingly common among the elderly. In daily life, these elderly people face huge challenges when walking, especially the pressure and impact of the upper body weight on the knee joints, which often aggravates their pain and discomfort, and may even accelerate the process of joint damage.

[0003] In order to alleviate this problem, a variety of walking aids have appeared on the market, such as knee aids and crutches. Knee aids are tied to the knees to provide additional support for the knee joints, aiming to reduce the pressure of the upper body on the knees when walking, while stabilizing the movement of the knee joints, thereby effectively relieving knee pain. Crutches, as another common walking aid, are mainly used to provide additional support, help maintain body balance, and reduce the risk of falling.

[0004] However, although these two tools have improved the walking conditions of the elderly to a certain extent, their independent designs limit their combined effectiveness. Specifically, the crutches only serve as auxiliary braces when walking and fail to directly participate in the process of reducing the pressure on the knee joints. Their effect in reducing the impact of the body on the knees is limited. At the same time, the separate use of crutches and knee aids lacks a collaborative working mechanism, which means that the elderly still need to mobilize more of their own strength to maintain body balance and reduce joint burdens when walking, which undoubtedly increases their physical exertion and walking difficulty. Summary of the invention

[0005] The purpose of the present invention is to provide a joint care auxiliary device for the elderly in view of the deficiencies of the prior art.

[0006] The specific technical solutions are as follows:

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0043] The joint care auxiliary device for the elderly provided in the present invention is referred to Figure 1-Figure 2 ,include:

[0044] A pair of supporting crutch structures 1 arranged opposite to each other, used to provide support for the upper body;

[0045] A knee assist device 3 connected to the hinge structure 2 and used to assist the knee joint; and

[0046] The hinged structure 2 is connected between the support crutch structure 1 and the knee assist device 3, and includes a hinged plate 1 21 and a hinged plate 22. One end of the hinged plate 1 21 is connected to the support crutch structure 1, one end of the hinged plate 22 is hinged to an end of the hinged plate 1 21 away from the support crutch structure 1, and the other end is hinged to the knee assist device 3.

[0047] The support crutch structure 1 and the knee assist device 3 are integrated into one design through the hinge structure 2, which enhances the stability of the user during walking and reduces the risk of falling. At the same time, the support crutch structure 1 is arranged under the armpits of the elderly to provide stable support for the elderly's upper body, reduce the pressure of the upper body on the knee joint, and effectively reduce the burden of the knee joint, hip joint and other joints in walking, standing and sitting by providing stable support for the elderly, thereby preventing and relieving joint pain and discomfort.

[0048] In this embodiment, refer to Figure 3 , the support crook structure 1 comprises:

[0049] Fixed sleeve 11;

[0050] The support rod 12 is adjustably inserted into the fixed sleeve 11;

[0051] The arc-shaped plate 13 is fixed to one end of the support rod 12 and is adapted to the armpit of the human body to distribute the weight of the upper body;

[0052] The driving member 14 is disposed on the fixed sleeve 11 and is used for driving the supporting rod 12 to move up and down.

[0053] Among them, the hinged plate 1 21 is hinged on the fixed sleeve 11 of the supporting crutch structure 1. Through the support design under the armpit, the pressure of the upper body on the knee joint of the elderly when walking is effectively dispersed, and the knee pain and discomfort caused by long-term walking or standing are reduced; the design of the arc plate 13 provides a stable and reliable support point for the elderly, enhances the safety during walking, and reduces the risk of falling. The height of the support rod 12 can be flexibly adjusted by the driving member 14 to adapt to the elderly with different heights and comfort requirements. Among them, the supporting crutch structure 1, as the basis of the entire auxiliary device, is made of lightweight and high-strength materials, such as aluminum alloy or carbon fiber, to ensure that it is both light and durable. When the elderly use the auxiliary device, they first adjust the height of the support rod 12 according to their personal height and comfort. By operating the driving member 14, the support rod 12 can be easily raised and lowered in the fixed sleeve 11; after the adjustment is completed, the crutch is placed under the armpit, and the support of the arc plate 13 is used to share the weight of the upper body. At the same time, the knee aid 3 is connected to the supporting crutch structure 1 through the hinge structure 2, which further improves the knee support. During walking, the overall stability of the crutch is effectively guaranteed, and the elderly can walk safely and comfortably while reducing the burden on the knees.

[0054] Specifically, refer to Figure 3-Figure 4 , the driving member 14 comprises:

[0055] A single-sided vertical tooth groove 141 is provided on the side wall of the support rod 12;

[0056] The driving gear 142 is meshed with the single-sided vertical tooth groove 141 and is rotatably connected to the fixed sleeve 11;

[0057] The worm gear combiner 143 is fixed to the fixed sleeve 11 and is used to drive the driving gear 142 to rotate.

[0058] Among them, the worm shaft of the worm-gear combiner 143 is fixedly connected to the shaft of the driving gear 142, and a handwheel 1431 is fixedly connected to the worm shaft of the worm-gear combiner 143. In addition, the worm-gear combiner 143 can adopt a WH series worm-gear reducer: including models such as WHT, WHX, WHS, and WHC. Through the provision of the unilateral vertical tooth groove 141, the driving gear 142, and the worm-gear combiner 143 and other components, the height of the support rod 12 is accurately and conveniently adjusted, so that the auxiliary device can adapt to the elderly with different height differences and meet their personalized needs. As an efficient and stable transmission mechanism, the worm-gear combiner 143 ensures the stability and reliability of the driving process. At the same time, the meshing design of the unilateral vertical tooth groove 141 and the driving gear 142 also enhances the stability of the support rod 12 during the adjustment process. The introduction of the handwheel 1431 enables the user to easily and intuitively operate the driving member 14, and the height adjustment of the support rod 12 can be completed without complicated tools or steps. When the user needs to adjust the height of the support rod 12, he only needs to rotate the hand wheel 1431 to drive the worm shaft to rotate, and the rotation of the worm will drive the worm wheel to rotate, and then the worm wheel shaft drives the driving gear 142 to rotate. Since the driving gear 142 is meshed with the single-sided vertical tooth groove 141, the rotation of the driving gear 142 will drive the support rod 12 to move up and down along its length. The user can accurately adjust the height of the support rod 12 by rotating the hand wheel 1431 according to his own height and comfort requirements. The entire adjustment process is smooth, stepless and easy to operate.

[0059] In this embodiment, refer to Figure 5-Figure 8, the auxiliary lifting component 5 for assisting the lifting of the knee assist device 3 along the advancing direction of the elderly on the supporting crutch structure 1, the auxiliary lifting component 5 comprises a fixed rod 51 fixedly connected to the two supporting rods 12, a support rod 52 fixedly connected to the fixed rod 51, a rocker 53 symmetrically arranged on both sides of the support rod 52, and a hinge plate 3 54 hinged on the rocker 53 and hinged to the knee assist device 3. The auxiliary lifting component 5 provides additional assistance for the elderly to lift their legs and walk by mechanical assistance, effectively reducing the force consumed by their leg lifting and reducing the walking burden. The lifting of the knee assist device 3 enables the elderly's knees to be better supported and assisted during walking, thereby improving the efficiency and stability of walking. The design of the auxiliary lifting component 5 fully considers the physical characteristics and walking habits of the elderly, so that the elderly can feel a more comfortable and natural walking experience during use. When the elderly walk, their leg movements will drive the supporting crutch structure 1 and the auxiliary lifting component 5 to move together. During walking, the elderly's knees will naturally lift forward, and the knee assist device 3 will rise accordingly. Since the rocker 53 in the auxiliary lifting member 5 is connected to the hinge plate 3 54, when the knee assist device 3 rises, the hinge plate 3 54 will be driven to rise, and then the rocker 53 will rotate around the support rod 52 through the lever action, and this rotation will further push the knee assist device 3 to rise, providing more support and assistance for the elderly's knees. As the elderly continue to move forward, the auxiliary lifting member 5 will continue to repeat the above process, providing continuous assistance for the elderly to walk.

[0060] Specifically, refer to Figure 6 , a moving wheel 111 is fixedly installed at one end of the fixed sleeve 11 away from the support rod 12 by screws. Among them, the moving wheel 111 is set with a movable caster, and the moving wheel 111 is made of a wear-resistant, silent and elastic material, such as rubber or polyurethane, to ensure that it can move smoothly and smoothly on a variety of grounds, which not only ensures sufficient load-bearing capacity, but also avoids excessive noise or vibration with the ground during movement. In addition, the moving wheel 111 is equipped with an anti-skid device in the prior art to prevent side slipping on wet or uneven ground. The addition of the moving wheel 111 enables the support crutches structure 1 to be easily moved when needed, providing great convenience for the elderly: whether indoors or outdoors, the elderly can walk, turn or cross obstacles more freely. When the elderly need to move the crutches, they only need to gently push the crutches to make the moving wheel 111 roll on the ground. Since the moving wheel is made of a wear-resistant and elastic material, it can slide smoothly over various grounds. At the same time, the design of the double-wheel or multi-wheel structure and the anti-skid device ensures the stability of the crutch during movement. When the elderly need the crutch to provide support, they only need to place the crutch vertically and rely on the support of the support rod 12 and the curved plate 13. At this time, the moving wheel 111 will not affect the stability of the crutch.

[0061] In this embodiment, with reference to 6, a reinforcing rod 4 is fixedly connected to the fixed sleeve 11 along the advancing direction of the elderly, and the reinforcing rod 4 is fixedly installed with a moving wheel 2 41 located in the same plane as the lowest point of the moving wheel by screws. Among them, the reinforcing rod 4 is made of a high-strength material that is the same or similar to the fixed sleeve 11 to ensure that while providing sufficient support, the overall weight of the crutch will not be increased or the convenience of use will not be affected. The addition of the reinforcing rod 4 and the moving wheel 2 41 allows the crutch to form multiple points of support during movement, greatly improving its stability. Even on uneven or slippery ground, the elderly can use the crutch to walk more safely. The coordinated design of the moving wheel 1 111 and the moving wheel 2 41 ensures the balance of the crutch during movement. The lowest points of the two are located in the same plane, avoiding shaking or rollover caused by height difference. When the elderly use crutches to walk, the moving wheel 1 111 and the moving wheel 2 41 roll on the ground at the same time to form a stable double-wheel or multi-wheel support. The reinforcing rod 4 serves as a bridge connecting the fixed sleeve 11 and the moving wheel 2 41, which not only provides additional support but also ensures the overall stability of the crutch during movement. During walking, the elderly can rely on the support of the support rod 12 and the curved plate 13 to maintain body balance, while using the rolling of the moving wheel to easily move the crutch. This design allows the crutch to provide stable support while also having good mobility.

[0062] In this embodiment, an elastic pad 131 in contact with human skin is fixedly connected to the curved plate 13. Among them, the elastic pad 131 is made of highly elastic and low-sensitivity materials, such as memory foam, highly elastic silicone or high-quality sponge, etc., which not only has good resilience, can closely fit the skin contour of the elderly and reduce the sense of oppression; it also has excellent breathability, can effectively perspire, prevent moisture, and keep the skin dry and comfortable. In addition, the surface of the elastic pad 131 is also specially treated, such as antibacterial and anti-mite, to ensure hygienic safety during long-term use. The elastic pad 131 is fixed to the curved plate 13 by firmly bonding, sewing or snapping, etc., to ensure that it will not fall off or shift during use. The addition of the elastic pad 131 makes the contact between the curved plate 13 and the skin of the elderly softer and more comfortable, reducing the sense of oppression and discomfort that may be caused by long-term use of crutches. The selection of high-quality materials and the design of breathability enable the elastic pad 131 to effectively perspire and prevent moisture during use, keep the skin dry and comfortable, and avoid skin problems caused by moisture. When the elderly place the crutch under the armpit, the elastic pad 131 on the curved plate 13 will fit the elderly's skin contour closely. Since the elastic pad 131 is made of highly elastic material, it can be fine-tuned according to the elderly's body shape and movements to ensure that stable and comfortable support is always provided. At the same time, the air permeability of the elastic pad 131 allows effective perspiration and moisture resistance during use, keeping the skin dry and comfortable. This design not only improves the comfort of the crutch, but also enhances its hygiene, safety and durability.

[0063] Reference Figure 7, the fixing rod 51 is in a U shape, and the fixing sleeve on the fixing rod 51 is symmetrically provided with an anti-slip sleeve 511. The U-shaped fixing rod 51 not only provides a stable support structure, so that the auxiliary lifting member 5 can be stably connected to the supporting crutch structure 1, but also forms an area that is convenient for hand gripping. When the elderly stand, they can naturally place their hands at the opening of the U-shaped fixing rod 51, and share the pressure of the armpit on the curved plate 13 by holding the fixing rod 51, thereby reducing discomfort. The setting of the anti-slip sleeve 511 further increases the friction between the hand and the fixing rod 51, preventing the inconvenience or safety hazard caused by the hand slipping during standing or walking. The anti-slip sleeve 511 is also made of materials with a high friction coefficient, such as rubber or silicone, which not only have good anti-slip properties, but also provide a comfortable grip. The design of the U-shaped fixing rod 51 enables the elderly to relieve the pressure of the armpit on the curved plate 13 by holding the hand when standing, thereby improving the comfort and safety of use. The provision of the anti-skid sleeve 511 enhances the friction between the hand and the fixed rod 51, prevents the hand from slipping, and improves the stability of the grip. By reducing the pressure on the armpit and improving the stability of the grip, the safety of the entire auxiliary lifting device during use by the elderly is significantly improved. When the elderly stand and need to reduce the pressure of the armpit on the curved plate 13, they will naturally place their hands at the opening of the U-shaped fixed rod 51. Due to the stable support of the fixed rod 51 and the anti-skid performance of the anti-skid sleeve 511, the elderly can hold the fixed rod 51 stably. As the hand exerts force on the fixed rod 51, part of the weight originally borne by the armpit is transferred to the arm, thereby reducing the pressure of the armpit on the curved plate 13. This design allows the elderly to use the auxiliary lifting device more easily and comfortably while standing or walking.

[0064] Reference Figure 8The rocker 53 is L-shaped, and the two rockers 53 are Z-shaped when in use. The Z-shaped rocker 53 layout can provide a wider support area, increase the friction between the auxiliary device and the ground, thereby improving the stability of the user when walking or standing, and the rocker 53 is fixed with an anti-skid cover 2 531. The anti-skid cover 2 531 is made of materials with a high friction coefficient, such as rubber or silicone, which not only have good anti-skid properties, but also provide a comfortable grip. The anti-skid cover 2 531 significantly enhances the friction between the hand and the rocker 53, so that the elderly can hold the rocker 53 more stably during walking, reducing accidents caused by hand slippage. The presence of the anti-skid cover 2 531 improves the overall safety of the auxiliary lifting component 5 and ensures the stability and comfort of the elderly during use. The anti-skid cover 2 531 can also protect the rocker 53 from erosion by hand sweat, grease and other substances to a certain extent, thereby extending the service life of the auxiliary lifting component 5. When the elderly walk and need to lift the knee aid 3, they will rotate the rocker 53 by holding the anti-skid cover 2 531 with their hands. The high friction coefficient of the anti-skid cover 2 531 allows the hand to fit more closely on the rocker 53, and maintain a good grip even when sweating or the hands are wet. As the rocker 53 rotates, the anti-skid cover 2 531 will rotate with it, but because it is firmly fixed to the rocker 53, it will not fall off or shift. This design ensures that the elderly can stably control the rotation of the rocker 53 during walking, thereby achieving the lifting and forward movement of the knee aid 3. At the same time, the comfortable grip of the anti-skid cover 2 531 also enhances the user experience of the elderly.

[0065] Working principle: Before walking, place the arc plate 13 under the armpit, and the elastic pad 131 fits the skin contour to support the weight of the upper body and reduce the pressure on the knee joint; rotate the hand wheel 1431 to drive the worm gear combiner 143, drive the driving gear 142 and the single-sided vertical tooth groove 141, and adjust the height of the support rod 12. When walking, the knee is naturally lifted, and the knee aid 3 and the auxiliary lifting component 5 work together to lift the knee aid 3 and assist in lifting the leg through the lever principle and the rotation of the rocker 53; the moving wheel 1 111 and the moving wheel 2 41 ensure the smooth movement of the crutch, and the reinforcing rod 4 provides additional support to maintain the stability of the crutch under different ground conditions. In addition, the anti-slip cover 1 511 and the anti-slip cover 2 531 provide a good grip, reduce the risk of slipping, and ensure safety and comfort during use.
