A height adjustable walking aid with non-slip feet

Abstract

This invention relates to the field of walking aids, specifically to a height-adjustable walking aid with anti-slip legs. It includes two U-shaped legs, with an adjustment tube fixed to the top of each leg and four wheels at the bottom. A sliding column is slidably connected to the inner wall of the adjustment tube. A single handrail is fixed to one side of each sliding column, and a support is fixed to one side of each leg. A pedal is fixed between the two supports. With this invention, the user can automatically convert the side protective plates into a stable seat without leaving the device or losing stable support by simply stepping on it with one foot. This completely avoids the risk of imbalance caused by cumbersome operation and lack of transitional support during mode switching in existing devices. Furthermore, the handrail height can be adjusted using the same pressure plate, making operation extremely simple. This allows patients with mobility impairments to more independently and confidently perform alternating walking and resting exercises, effectively enhancing the practicality of rehabilitation equipment.

Description

Technical Field

[0001] This invention relates to the field of walking aids, and more particularly to a height-adjustable walking aid with anti-slip feet. Background Technology

[0002] Assisted walking training equipment is an important tool in the field of rehabilitation medicine to help patients regain their walking function. Existing dual-purpose walking devices generally integrate both walking assistance and sitting rest functions, but there are still obvious design flaws in actual use, mainly in terms of the ease of switching between functions and user safety.

[0003] When patients need to switch from standing and walking mode to sitting and resting mode, they often need to first remove themselves from the walker support, walk around to the side or back of the seat, and then turn around and sit down. This process is not only cumbersome and difficult for rehabilitation patients with limited mobility and physical strength, but also temporarily loses the effective support of the equipment during the switching process, posing a risk of imbalance or falling. When adjusting the armrests or seat height in a sitting position, it usually requires both hands to operate a complex locking mechanism, which makes the patient's body lack stable support, inconvenient to operate, and prone to causing discomfort.

[0004] Therefore, current dual-purpose walking aids do not yet achieve seamless transition support and convenient one-handed (or one-foot) operation during mode switching and posture adjustment, resulting in a less than smooth user experience, especially for patients with weaker physical strength and poor balance. How to enable patients to safely, easily, and quickly switch between walking and sitting postures and make corresponding adjustments without significant body movement or loss of support has become a key issue in improving the practicality and user-friendliness of such devices. Therefore, a height-adjustable walking aid with anti-slip feet is proposed to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by providing a height-adjustable walking aid with anti-slip feet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A height-adjustable walking aid with anti-slip feet includes two U-shaped feet, an adjustment tube fixed to the top of the two U-shaped feet, four driving wheels at the bottom of the two U-shaped feet, a sliding column slidably connected to the inner wall of the adjustment tube, a handrail fixed to one side of the two sliding columns, a bracket fixed to one side of the two U-shaped feet, and a pedal fixed between the two brackets. The U-shaped support leg has two rotating rings on its external rotating connection. The outer walls of the two rotating rings are fixed with the same side plate. The side of the two rotating rings away from the side plate is fixed with a baffle. A support plate is fixed to one side of the U-shaped support leg. The outer wall of the support plate is fixed with three rings. The outer wall of the rings is surrounded by an arc spring. The two ends of the arc spring are fixed to the support plate and the side plate. The side plate is slidably connected to the outer wall of the ring. Several evenly distributed adjustment ports are opened on both sides of the adjustment tube. Two locking blocks are slidably connected to the bottom of the sliding column. An adjustment block is set between the two locking blocks. The adjustment block is slidably connected to the sliding column. The two adjustment ports are slidably connected to the adjustment block through a slide rod. An inner slide rod is fixedly connected to the top of the adjustment block. The inner slide rod is slidably connected to the sliding column. A pressure plate is fixedly connected to the top of the inner slide rod. Several first springs are fixedly connected between the pressure plate and the sliding column.

[0007] A connecting block is slidably connected to the bottom of the sliding column, and an inclined sliding rod is fixed to one side of the connecting block. Two evenly distributed second springs are fixed between the top of the connecting block and the sliding column.

[0008] Two mounting blocks are fixed to the bottom of the pedal, and the inner sides of the two mounting blocks are rotatably connected to the same rotating shaft.

[0009] A foot plate is fixed to one side of the rotating shaft, and traction wheels are fixed to both ends of the rotating shaft. Pull ropes are fixed to the outer walls of the traction wheels.

[0010] A guide frame is fixed to one side of the support, and a pull rope passes through the bottom of the guide frame.

[0011] The end of the pull rope away from the guide frame is fixed to the connecting block, and several evenly distributed guide blocks are fixed to one side of the U-shaped support.

[0012] The pull rope is installed through the guide block.

[0013] Two mounting plates are fixed to the side of the handrail near the sliding column, and an operating lever is installed on the top of the mounting plates.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a foot pedal to drive a traction wheel that pulls a rope, allowing the patient to perform a simple stepping action with one foot to automatically drive the two side panels to rotate and fold together, forming a stable seat surface. This avoids the need for the patient to perform complicated operations or receive assistance from others to sit down, and the transition process is natural, effortless, and less prone to tipping over.

[0015] The downward-pressing unlocking mechanism, consisting of a pressure plate and an adjusting block, releases the jamming of the adjusting port, allowing the height of the sliding column to be freely adjusted. After being released, the locking block automatically pops out and engages with the corresponding adjusting port under the action of the return spring, achieving self-locking.

[0016] The two side panels form physical barriers on both sides of the patient, and together with the handrail in front, they create a U-shaped safety zone, greatly improving the safety of training without affecting the patient's normal gait. Attached Figure Description

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.

[0021] Reference Figure 1 - Figure 8 A height-adjustable walking aid with anti-slip feet includes two U-shaped feet 3, an adjustment tube 9 fixedly connected to the top of the two U-shaped feet 3, four travel wheels 1 provided at the bottom of the two U-shaped feet 3, a sliding column 12 slidably connected to the inner wall of the adjustment tube 9, a handrail frame 16 fixedly connected to one side of the two sliding columns 12, a bracket 17 fixedly connected to one side of the two U-shaped feet 3, and a pedal 21 fixedly connected between the two brackets 17. The U-shaped support leg 3 has two rotating rings 6 on its outside. The outer walls of the two rotating rings 6 are fixed with the same side plate 8. The side of the two rotating rings 6 away from the side plate 8 is fixed with a baffle 32. The side of the U-shaped support leg 3 is fixed with a support plate 2. The outer wall of the support plate 2 is fixed with three circular rings 5. The outer wall of the circular rings 5 ​​is surrounded by an arc spring 4. The two ends of the arc spring 4 are fixed with the support plate 2 and the side plate 8. The side plate 8 is slidably connected to the outer wall of the circular rings 5. A connecting block 28 is slidably connected to the bottom of the sliding column 12. An inclined sliding rod 7 is fixed to one side of the connecting block 28. Two evenly distributed second springs 29 are fixed between the top of the connecting block 28 and the sliding column 12.

[0022] Two mounting blocks 18 are fixed to the bottom of the pedal 21, and the inner sides of the two mounting blocks 18 are rotatably connected to the same rotating shaft 20.

[0023] A footplate 19 is fixedly connected to one side of the rotating shaft 20. Traction wheels 22 are fixedly connected to both ends of the rotating shaft 20. A pull rope 24 is fixedly connected to the outer wall of the traction wheel 22. A guide frame 25 is fixedly connected to one side of the bracket 17. The pull rope 24 passes through the bottom of the guide frame 25. The end of the pull rope 24 away from the guide frame 25 is fixedly connected to the connecting block 28. Several evenly distributed guide blocks 23 are fixedly connected to one side of the U-shaped support leg 3. The pull rope 24 is installed through the guide block 23.

[0024] In this implementation plan, the patient stands between two side panels 8 and holds onto the handrail frame 16 with both hands to perform assisted walking exercises. The side panels 8 on both sides can provide protection for the patient in the middle. When the patient needs to rest, he only needs to press his abdomen against the handrail frame 16 and lift one foot to step on the footplate 19. The footplate 19 drives two traction wheels 22 to rotate through the rotating shaft 20. The two traction wheels 22 pull the pull rope 24 and the connecting block 28. The connecting block 28 pulls the inclined slide bar 7. The inclined surface of the inclined slide bar 7 abuts against the side panels 8, causing the side panels 8 to rotate in opposite directions.

[0025] The regulating tube 9 has several evenly distributed regulating ports 10 on both sides. The bottom of the sliding column 12 is slidably connected to two locking blocks 11. An regulating block 31 is provided between the two locking blocks 11. The regulating block 31 is slidably connected to the sliding column 12. The two regulating ports 10 are slidably connected to the regulating block 31 through a sliding rod 30. An inner sliding rod 27 is fixedly connected to the top of the regulating block 31. The inner sliding rod 27 is slidably connected to the sliding column 12. A pressure plate 13 is fixedly connected to the top of the inner sliding rod 27. Several first springs 26 are fixedly connected between the pressure plate 13 and the sliding column 12.

[0026] Two mounting plates 15 are fixed to the side of the handrail 16 near the sliding column 12, and an operating lever 14 is provided on the top of the mounting plate 15.

[0027] In this embodiment, the patient sits on the two side panels 8, then places both feet on the pedal 21 and presses down on the pressure plate 13. The pressure plate 13 causes the inner slide rod 27 and the adjusting block 31 to move down. The locking block 11 is limited by the adjusting block 31 and retracts into the sliding column 12, thereby adjusting the height of the sliding column 12 and the handrail 16. When the appropriate height is reached, the pressure plate 13 is released so that the locking block 11 is engaged in the corresponding adjusting port 10, thus completing the height adjustment of the handrail 16. The sliding columns 12 on both sides are used to control the forward and backward movement and direction adjustment of the traveling wheels 1.

[0028] Working principle: The patient stands between the two side panels 8 and holds onto the handrail frame 16 with both hands to perform assisted walking exercises. The side panels 8 on both sides can protect the patient in the middle. When the patient needs to rest, he only needs to press his abdomen against the handrail frame 16 and lift one foot to step on the footplate 19. The footplate 19 drives the two traction wheels 22 to rotate through the rotating shaft 20. The two traction wheels 22 pull the pull rope 24 and the connecting block 28. The connecting block 28 pulls the inclined slide rod 7. The inclined surface of the inclined slide rod 7 abuts against the side panels 8, causing the side panels 8 to rotate in opposite directions.

[0029] The patient sits on the two side panels 8, then places both feet on the pedals 21 and presses down on the pressure plate 13. The pressure plate 13 causes the inner slide rod 27 and the adjusting block 31 to move down. The locking block 11 is limited by the adjusting block 31 and retracts into the sliding column 12, thereby adjusting the height of the sliding column 12 and the handrail 16. When the appropriate height is reached, the pressure plate 13 is released so that the locking block 11 is engaged in the corresponding adjusting port 10, completing the height adjustment of the handrail 16. The sliding columns 12 on both sides are used to control the forward and backward movement and direction adjustment of the travel wheels 1.

[0030] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
