Description

Technical Field

[0001] This utility model belongs to the field of knee support device technology. Specifically, this utility model relates to a support bracket for a knee joint walking aid. Background Technology

[0002] Wearable knee-joint walking aids, as a type of rehabilitation medical device that assists in walking and reduces the load on the knee joint, are widely used in rehabilitation training for patients with lower limb dysfunction and in assisting the daily travel of the elderly. Stable support is crucial for ensuring the safety and reliability of these walking aids. The lowermost support bracket, as a key grounding support component, directly affects the overall support effect and adaptability of the walking aid.

[0003] Existing wearable knee walking aids use a fixed structure design for their support legs. Their grounding methods mainly fall into two categories: wearing them outside or inside the shoe for combined contact with the ground. This stable contact with the ground provides bottom support for the knee walking aid, thereby assisting the knee joint in flexion, extension, and weight-bearing movements. In terms of assembly, the support leg needs to be connected above the user's ankle joint to achieve force transmission and structural coordination with the main body of the knee walking aid, ensuring that the walking aid moves synchronously with the user's lower limbs during walking.

[0004] However, existing technologies have significant drawbacks: the dimensions of the tripod (including length and connection fitting dimensions) are fixed and cannot be adjusted according to the different body characteristics of users. Due to significant individual differences in height, the ankle height varies among people of different heights—taller individuals have higher ankle heights from the ground, while shorter individuals have lower ankle heights. When using a fixed-size tripod, for users with higher ankle heights, the effective support length of the tripod is insufficient, easily leading to unstable grounding of the walker, center of gravity shift, and even the risk of tipping over. For users with lower ankle heights, the tripod may be too long, forming an abnormal angle with the ground, affecting walking flexibility, potentially causing uneven stress on the tripod, accelerated wear, and disrupting the coordination between the walker and the lower limbs, reducing comfort and safety.

[0005] Chinese Patent Application No. 202021045578.6 discloses a human lower leg support device, including a main support plate, a foot support plate, and a buffer block disposed on the foot support plate for providing elastic support to the main support plate. The technical solution disclosed in this patent document also fails to solve the aforementioned technical problem.

[0006] This invention provides a support bracket for a knee-supporting walking aid, with a particular focus on improving stability and comfort during use. Utility Model Content

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0017] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0018] like Figures 1 to 5 As shown, this utility model provides a support bracket for a knee joint walking aid, including a foot support plate. The foot support plate includes an upper connecting part 3 for connecting to the knee joint walking aid, a lower connecting part for connecting to the sole of a shoe, and an adjustment mechanism connecting the upper connecting part 3 and the lower connecting part. The distance between the upper connecting part 3 and the lower connecting part is adjustable.

[0019] Specifically, such as Figures 1 to 3 As shown, the adjustment mechanism includes a first adjustment plate 1 connected to the upper connecting part 3, a second adjustment plate 2 connected to the lower connecting part, and a locking member 6 connecting the first adjustment plate 1 and the second adjustment plate 2. The first adjustment plate 1 has a first mounting hole 9 for inserting the locking member 6, and the second adjustment plate 2 has a second mounting hole 10 for inserting the locking member 6. Multiple first mounting holes 9 and second mounting holes 10 are provided, with the number of first mounting holes 9 and second mounting holes 10 exceeding the number of locking members 6. All first mounting holes 9 on the first adjustment plate 1 are arranged sequentially along the length of the first adjustment plate 1, and all second mounting holes 10 on the second adjustment plate 2 are arranged sequentially along the length of the second adjustment plate 2. The first adjustment plate 1 is fixedly connected to the lower end of the upper connecting part 3, and the two are integrally formed. The upper end of the upper connecting part 3 is connected to the lower end of the knee joint walker via a pivot, forming a rotatable connection. The upper end of the upper connecting part 3 is located above the user's ankle joint. The second adjustment plate 2 is fixedly connected to the upper end of the lower connecting part, and the two are integrally formed.

[0020] like Figure 1 and Figure 2As shown, both the first mounting hole 9 and the second mounting hole 10 are round holes. The locking element 6 is a bolt, and at least two locking elements 6 are provided, with nuts attached to the bolts. Each bolt passes through an aligned first mounting hole 9 and a second mounting hole 10, fixing the first adjusting plate 1 and the second adjusting plate 2 together. The first adjusting plate 1 and the second adjusting plate 2 fit together, thus fixing the distance between the upper connecting part 3 and the lower connecting part. When it is necessary to adjust the distance between the upper connecting part 3 and the lower connecting part, the bolts and nuts are removed, and the bolts are inserted into the first mounting holes 9 and the second mounting holes 10 at different height positions. After tightening the bolts and nuts, the distance between the upper connecting part 3 and the lower connecting part can be adjusted. This adjustment mechanism has a simple structure, is easy to operate, and provides a firm connection after adjustment. Using bolts as locking elements 6, combined with the round hole design, can firmly fix the first adjusting plate 1 and the second adjusting plate 2 after height adjustment. The bolt locking method has a strong load-bearing capacity and can effectively resist external impacts during walking, helping to provide stable support for the user's knee joint.

[0021] like Figures 1 to 5 As shown, the lower connecting part includes a base plate 4 and a side plate 5 fixedly connected to the base plate 4. The base plate 4 is located below the sole, and the side plate 5 is located on the outside of the shoe worn by the user. The side plate 5 is connected to an adjustment mechanism and is fixedly connected to the lower end of the second adjustment plate 2. The side plate 5 is provided with a slot 8 for embedding the anti-slip shoe cover 7. The anti-slip shoe cover 7 is made of rubber. The anti-slip shoe cover 7 is worn on the shoe worn by the user and can wrap around the base plate 4. A portion of the anti-slip shoe cover 7 extends upward and passes through the slot 8 provided on the side plate 5 to achieve connection with the foot support plate. When in use, the elasticity applied by the anti-slip shoe cover 7 can make the foot support plate fit against the shoe and connect them into one piece.

[0022] like Figures 3 to 5 As shown, there are two foot support plates, which are symmetrical in structure, and the user's shoes are located between the two foot support plates.

[0023] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
