Description

Technical Field

[0001] This invention belongs to the technical field of walking aid devices, and specifically relates to a walking aid. Background Technology

[0002] A walking aid is a device that assists the human body in supporting its weight, maintaining balance, and walking. It is used by elderly people with limited mobility, certain injured individuals, hemiplegic patients, and people with disabilities to help them walk or exercise their limbs. People can walk slowly and easily with its support. Current methods for treating lower limb movement disorders generally involve passively flexing the patient's hip and knee joints with the help of family members. This is labor-intensive, cannot be sustained, and once the external force is reduced, the limbs revert to an external rotation position, making it impossible to maintain a functional position for an extended period. A walking aid can help address these issues.

[0003] Existing walking aids require binding and supporting various parts of the body to prevent patients from falling off the aid during movement and to provide some support. However, the binding and support structures of existing walking aids are not adaptable enough to different parts of the body and cannot be universally adjusted for people with different leg shapes and heights. This affects the comfort of patients and the effectiveness of the support and assistance. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a walking aid that solves the issues of insufficient adaptability and reduced comfort and support in existing walking aids. This walking aid has better adaptability and can be adjusted to suit people with different leg shapes and heights.

[0026] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0027] See Figures 1 to 8As shown, this invention discloses a walking aid, including a walking aid bracket, multiple mounting components, a hand support 35, a first lumbar support 44, a leg support structure, an arched frame 5, and a second lumbar support 11. The walking aid bracket includes a U-shaped support frame 10 for wrapping around the patient's waist. The mounting components include a sleeve 31, a metal spring 19, a lifting rod 30, a positioning screw 32, a hinge rod 14, a rotating screw 16, and a fixing knob 18. The lifting rod 30 slides into the sleeve 31, and multiple through holes 13 are spaced apart on the lifting rod 30. The positioning screw 32 passes through the sleeve 31 and one of the through holes 13 to limit the lifting rod 30. The top end of the metal spring 19 is sleeved on the sleeve 31, and a fixing hole 20 is formed between the metal spring 19 and the sleeve 31 for the U-shaped support frame 10 to pass through. The bottom of the sleeve 31 is provided with a first strip hole 15 and a second strip hole arranged parallel to each other at intervals. The metal spring 19 has a U-shaped groove 17 at its bottom.

A second lumbar support 11 is provided on the arched frame 5, thereby supporting and binding the human body in various directions. Compared with the existing walking aid structure, this walking aid improves the structure of the mounting components to make them more adjustable, thereby ensuring that the hand supports 35, the first lumbar supports 44, the leg supports, and the second lumbar supports 11 can adapt to the position of the human hand, waist, and leg, improving the patient's comfort.

[0029] Specifically, when adjusting the mounting component, first rotate the fixing knob 18 and rotate the rotating screw 16 to disengage the rotating screw 16 from the U-shaped groove 17. At this time, the clamping force between the metal spring 19 and the sleeve 31 on the U-shaped support frame 10 is small. The position of the sleeve 31 can be adjusted, or the U-shaped support frame 10 can be removed from or inserted between the metal spring 19 and the sleeve 31 to change its position. After determining the position, the rotating screw 16 can be rotated to pass through the U-shaped groove 17, and the fixing knob 18 can be tightened to increase the clamping force of the metal spring 19 on the U-shaped support frame 10, thereby fixing the sleeve 31. Then, adjust the height of the lifting rod 30 according to the required height and fix it with the positioning screw 32.

[0030] The hand rest 35 is provided with an arc-shaped groove 42 for placing the arm. The top of the arc-shaped groove 42 is provided with a fixing strap 43.

The third fastening screw 40 is used to fix the rotation angle of the gripper 41 on the rotating frame 39. The gripper 41 is for the patient to grasp and allows for angle adjustment according to the patient's needs.

[0033] The second mounting component 2 has a second horizontal groove 45 at the top of the lifting rod 30. The back of the first lumbar support 44 is connected to a second horizontal rod 46. The second horizontal rod 46 slides into the second horizontal groove 45. A fourth fastening screw 63 is provided on the outside of the side wall of the second horizontal groove 45. The fourth fastening screw 63 is threaded through the side wall of the second horizontal groove 45 and abuts against the outer wall of the second horizontal rod 46.

[0034] The positions of the first lumbar support 44 and the arched frame 5 are adjusted by the second mounting component 2 and the fourth mounting component 4. The position of the second lumbar support 11 changes with the position of the arched frame 5. The first lumbar support 44 and the second lumbar support 11 are arranged in a U-shape to support the lower back and left and right sides of the patient, effectively correct the patient's posture, and improve the effect of rehabilitation training.

[0035] The walking aid also includes a back support 12, which is detachably mounted on the arched frame 5.

[0036] The leg support structure includes a support bar 51, a limiting screw, a limiting knob 48, and a fixing belt ring 47.

One end of the limiting screw has an enlarged end 50, and the other end of the limiting screw passes through the adjustment strip hole 49 and the limiting hole in sequence, and is threadedly connected to the limiting knob 48. The enlarged end 50 abuts against the surface of the support bar 51, and the limiting knob 48 abuts against the surface of the mounting component to provide a limiting effect. The end of the support bar 51 and the fixing belt ring 47 are rotatably connected about a vertical axis. Adjusting the third mounting component 3 allows the fixing belt ring 47 to align with the patient's thigh, improving patient comfort and support when using the walker.

[0037] The walking aid bracket includes wheels 6, a U-shaped base 9, two height adjustment rods 8, and a U-shaped support frame 10. The bottom ends of the two height adjustment rods 8 are connected to the U-shaped base 9, and the top ends of the two height adjustment rods 8 are connected to the U-shaped support frame 10. There are multiple wheels 6, and multiple wheels 6 are installed below the U-shaped base 9.

[0038] The height adjustment rod 8 includes a bottom connecting cylinder 62, a top adjustment rod 59, a fixing pin 61, and a U-shaped hook 60. The top adjustment rod 59 is retractably inserted into the bottom connecting cylinder 62. The side wall of the top adjustment rod 59 is provided with multiple adjustment holes, which are spaced apart along the length of the top adjustment rod 59. The fixing pin 61 passes through one side wall of the bottom connecting cylinder 62, one of the adjustment holes, and the other side wall of the bottom connecting cylinder 62 in sequence, and both ends of the fixing pin 61 protrude from the bottom connecting cylinder 62. One end of the U-shaped hook 60 rotates around one end of the fixing pin 61, and the other end of the U-shaped hook 60 is detachably sleeved on the other end of the fixing pin 61.

[0039] When adjusting the height, the fixing pin 61 can be removed from the bottom connecting cylinder 62. At this time, the relative height between the top adjusting rod 59 and the bottom connecting cylinder 62 can be adjusted. After adjustment, the fixing pin 61 is passed through one side wall of the bottom connecting cylinder 62, one of the adjusting holes, and the other side wall of the bottom connecting cylinder 62 in sequence to fix the relative position of the top adjusting rod 59 and the bottom connecting cylinder 62. At this time, the U-shaped hook 60 is rotated so that the other end of the U-shaped hook 60 is sleeved on the other end of the fixing pin 61 to prevent the fixing pin 61 from detaching from the bottom connecting cylinder 62, forming a stable connection and positioning effect. Moreover, this structure is easy to install and operate.

[0040] The walking aid also includes two mounting rods 57 and two ankle straps 7. The two mounting rods 57 are arranged parallel to each other on both sides of the bottom of the U-shaped base 9. The two ankle straps 7 are slidably mounted on the two mounting rods 57. Two torsion springs 56 are spaced apart on each mounting rod 57. The ankle straps 7 are located between the two torsion springs 56. Each torsion spring 56 extends to a first end 53 and a second end 54. When force is applied to the first end 53 and the second end 54, the first end 53... One end 53 and the second end 54 are close to each other, and the clamping force of the torsion spring 56 on the mounting rod 57 decreases, allowing the torsion spring 56 to slide relative to the mounting rod 57. When the force applied to the first end 53 and the second end 54 is removed, the first end 53 and the second end 54 recover their deformation under the action of elasticity, and the clamping force of the torsion spring 56 on the mounting rod 57 increases. The torsion spring 56 is fixed to the mounting rod 57, and an adjustable binding ring 55 for fixing the ankle is provided at the end of the ankle binding strap 7 away from the mounting rod 57.

[0041] The bottom of the U-shaped base 9 is provided with a first mounting seat 52 and a second mounting seat 58 spaced apart, and the two ends of the mounting rod 57 are detachably mounted on the first mounting seat 52 and the second mounting seat 58.

[0042] The U-shaped base 9 is linked to the patient's ankle by the ankle strap 7. At the same time, in order to facilitate the adjustment of the patient's ankle movement range, two torsion springs 56 are provided. By applying force to the first end 53 and the second end 54, the distance between the two torsion springs 56 on the mounting rod 57 can be adjusted, thereby limiting the movement range of the ankle strap 7, adapting to the movement range requirements of different patients, and avoiding the problem of falling due to excessive movement range.

[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
