Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to an adjustable multifunctional gait training device. Background Technology

[0002] In the field of medical rehabilitation, gait training is a crucial step in restoring normal walking ability for patients with gait dysfunction caused by various reasons, such as stroke, brain injury, and lower limb fracture surgery. Traditional gait training methods mainly rely on simple walking aids, such as crutches and walking aids, or training on steps of fixed height and structure.

[0003] Existing gait training devices have many limitations. For example, most fixed-structure step training devices cannot flexibly adjust the height and spacing between the steps according to the patient's actual rehabilitation progress and physical condition. This may not provide the most suitable training conditions for patients at different stages of recovery. If the step height is too high, it may cause the patient to fall during training, increasing the risk of injury; if the step height is too low, it will not achieve effective training results and will delay the rehabilitation process.

[0032] Example 1

[0033] Reference Figures 1 to 4 As one embodiment of this utility model, an adjustable multifunctional gait training device is provided, allowing trainees to perform gait training in an environment with adjustable height steps and effective upper limb support, including:

[0034] The stepped training mechanism 100 consists of a base plate 101 and several horizontally arranged pedals 102, which are parallel to each other and connected by a linkage assembly. The base plate 101 serves as the basic support component of the entire device, providing a stable platform for the installation of other components. The pedals 102 are used by trainees to stand and perform gait training movements, and the arrangement of multiple pedals 102 simulates a stepped training environment.

[0035] Vertical guide rods 103 are symmetrically arranged on the base plate 101, and the topmost pedal 102 is slidably sleeved on the guide rods 103. The function of the guide rods 103 is to guide the movement of the topmost pedal 102, ensuring that it maintains stable vertical movement during lifting and lowering, avoiding deviation, and enhancing the stability of the device operation.

[0036] The stepped training mechanism 100 also includes an upper limb support unit for supporting the trainee's upper limbs. The upper limb support unit comprises two symmetrically arranged single-sided support components 108 on the stepped training mechanism 100. Two vertically arranged brackets 109 within the single-sided support components 108 are fixed to two different height steps 102, serving to connect and support the handrails 110. The handrails 110 are located at the top of the brackets 109 and are rotatably connected to them. During gait training, the trainee can grip the handrails 110 with both hands, providing support for the upper limbs, helping the trainee maintain better balance during training, and reducing the risk of falls due to insufficient upper limb support.

[0037] The handrail 110 is covered with a protective sleeve 111 made of elastic cushioning material. The protective sleeve 111 consists of an outer rubber layer 112 and an inner cushioning cotton layer 113. The outer rubber layer 112 has a certain degree of wear resistance and anti-slip properties, which can increase the stability of the trainee's grip; the inner cushioning cotton layer 113 can provide a soft and comfortable feel when the trainee grips it, and can also play a cushioning and protective role when the trainee accidentally bumps into the handrail 110, reducing the chance of injury.

[0038] Drive mechanism 200: Located on the base plate 101 with its output end connected to the top pedal 102, it drives the pedal 102 to reciprocate along the guide rod 103. The function of drive mechanism 200 is to provide power to adjust the height of pedal 102 to suit the needs of different trainees.

[0039] The trainee first determines whether the height of the pedals 102 needs adjustment based on their own situation. If adjustment is needed, the drive mechanism 200 is activated (via an external control button, etc.). The drive mechanism 200 operates, causing the top pedal 102 to rise or fall along the guide rod 103. Because the pedals 102 are connected by a linkage component, as the top pedal 102 moves, the other pedals 102 move synchronously, thus adjusting the height of the entire stepped training mechanism 100. After adjusting to a suitable height, the angle of the handrail 110 adapts to the changing height difference of the pedals 102, maintaining a suitable support angle. The trainee stands on the stepped training mechanism 100, grips the handrail 110 of the upper limb support unit with both hands, and then begins gait training movements such as leg raises and steps. During training, the upper limb support unit provides support for the trainee, while the protective sleeve 111 provides a comfortable grip and cushioning protection.

[0040] Trainees can perform gait training in an environment with adjustable height steps and effective upper limb support. The adjustable height of the step 102 allows the device to meet the needs of different trainees and the same trainee at different stages of rehabilitation; the upper limb support unit and protective sleeve 111 greatly improve the safety and comfort during training, helping trainees to better complete gait training and promote the rehabilitation process.

[0041] Example 2

[0042] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the linkage component consists of several scissor structures 201. Each scissor structure 201 includes a horizontal bar 202 and a vertical bar 203. The horizontal bar 202 is horizontally positioned and fixedly installed on the pedal 102. The middle positions of the vertical bar 203 and the horizontal bar 202 within the same scissor structure 201 are rotatably connected via a pivot. The ends of the horizontal bar 202 and the vertical bar 203 in adjacent scissor structures 201 are rotatably connected via a pivot. Adjacent horizontal bars 202 and adjacent vertical bars 203 are arranged parallel to each other. This linkage component design of the scissor structure 201 allows the remaining pedals 102 to move synchronously when the top pedal 102 moves under the action of the drive mechanism 200, through the rotatable connection between the horizontal bar 202 and the vertical bar 203, achieving flexible and stable adjustment of the height and spacing between the pedals 102. Compared to other simple connection methods, the scissor structure 201 has better stability and adjustability, can withstand greater pressure and weight, and ensures the reliability of the pedal 102 structure during training.

[0043] The drive mechanism 200 includes a screw 204 rotatably mounted on a base plate 101 and a drive motor 205 fixed to the base plate 101. A boss 206 is fixedly connected to the base plate 101, and a rotating rod 207 is rotatably connected to the boss 206. A worm gear 208 is fixedly sleeved on the rotating rod 207. A worm wheel 209, coaxially arranged with the screw 204, is fixedly sleeved on the screw 204. The output end of the drive motor 205 is connected to the rotating rod 207 for transmission. A threaded sleeve 210, threadedly engaged with the screw 204, is fixedly installed at the bottom of the top pedal 102. When the drive motor 205 starts, its output end drives the rotating rod 207 to rotate, and the worm gear 208 on the rotating rod 207 rotates accordingly. Since the worm gear 208 meshes with the worm wheel 209, the worm wheel 209 drives the screw 204, which is coaxially arranged with it, to rotate. Furthermore, because the threaded sleeve 210 at the bottom of the top pedal 102 is threadedly engaged with the screw 204, the rotation of the screw 204 causes the top pedal 102 to move up and down along the guide rod 103, thereby driving the other pedals 102 to adjust their height and spacing synchronously through the linkage assembly. This drive mechanism 200 design utilizes a motor to provide power, and through worm gear 208, worm wheel 209, and threaded transmission, it achieves precise and stable adjustment of the pedal 102 height, making it convenient to operate and easy to control.

[0044] A frame 104 is symmetrically arranged on the base plate 101, and sliders 105 are symmetrically arranged on the bottom pedal 102, slidingly engaging with the frame 104. The sliders 105 are located inside the frame 104. The arrangement of the frame 104 and sliders 105 further enhances the stability of the pedal 102 during movement, preventing the pedal 102 from deviating in the horizontal direction. During the raising and lowering of the pedal 102, the sliders 105 slide within the frame 104, limiting and guiding the pedal 102, ensuring the stable operation of the entire stepped training mechanism 100.

[0045] The pedal 102 is equipped with a rubber pad 106, on which several arrayed anti-slip grooves 107 are formed. The rubber pad 106 has a certain degree of elasticity and friction, and the anti-slip grooves 107 further increase the friction. When the trainee trains on the pedal 102, the rubber pad 106 and the anti-slip grooves 107 can effectively prevent the trainee's shoe sole from slipping on the pedal 102, improving safety during training.

[0046] Before training begins, if the height of pedal 102 needs to be adjusted, the drive motor 205 is started. The drive motor 205 rotates, causing the rotating rod 207 to rotate, which in turn drives the screw 204 to rotate via the worm gear 208 and worm wheel 209, thereby causing the top pedal 102 to rise or fall along the guide rod 103. During the movement of the top pedal 102, the linkage component of the scissor mechanism 201 functions, causing the other pedals 102 to adjust their height and spacing synchronously. After adjusting to a suitable training height, the trainee stands on the pedal 102 of the stepped training mechanism 100. Because the pedal 102 has rubber pads 106 and anti-slip grooves 107, sufficient friction between the feet and the pedal 102 ensures stability. The trainee holds the handrails 110 of the upper limb support unit (the upper limb support unit structure is the same as in Example 1) and then begins gait training movements, such as leg lifts and steps. During training, the frame 104 and slider 105 ensure the stable operation of the pedal 102, the rubber pad 106 and anti-slip groove 107 prevent slipping, the upper limb support unit provides support, and the protective sleeve 111 provides comfortable grip and cushioning protection.

[0047] Based on Example 1, this embodiment further improves the stability, adjustability, and safety of the device by optimizing the design of the linkage components and drive mechanism, and by adding structures such as the frame, slider, rubber pad, and anti-slip groove. The precise drive mechanism and stable linkage components allow the pedal height and spacing to more accurately adapt to different training needs; the frame, slider, rubber pad, and anti-slip groove structures ensure the safety and reliability of the training process from multiple aspects, providing better training conditions for trainees and further promoting gait training effects and rehabilitation progress.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
