Description

Technical Field

[0001] This utility model relates to the field of walking aids, and more specifically, to a portable single-leg walking aid. Background Technology

[0002] In daily life and rehabilitation, single-leg walkers are widely used as important assistive walking devices for patients with lower limb injuries, post-operative recovery, or limb dysfunction, especially suitable for rehabilitation populations who only require unilateral support. These walkers typically consist of a handle, support bar, leg support structure, and bottom movement mechanism. By providing stable support to one side of the user's body, they help maintain balance and gradually achieve basic activities such as independent standing and slow walking. Compared to traditional crutches or walking frames, single-leg walkers have a more compact structure, are more flexible in use, and are suitable for patients to use in early rehabilitation training and daily walking assistance in different environments such as home, hospital, or rehabilitation center.

[0003] However, existing single-leg walking aids still have many limitations in use, especially in terms of human adaptability. Most traditional walking aids have handle components designed with a fixed height and angle, lacking adjustment capabilities. This makes it difficult to flexibly adjust to different patients' heights, arm lengths, or postural habits, resulting in unnatural wrist angles and uneven arm force during gripping, easily leading to fatigue or discomfort. Furthermore, the fixed grip angle hinders fine-tuning support in different scenarios, especially on slopes or in confined spaces, affecting overall safety and comfort. Therefore, there is an urgent need for a single-leg walking aid with a more ergonomic structure and adjustable handle height and angle to improve its adaptability and practical effectiveness.

[0004] Therefore, this application provides a portable single-leg walking aid. Utility Model Content

[0013] The present invention is further configured such that: the leg support member further includes a lower mounting strip installed on one side of the lower mounting block, and a lower fixing strap is attached to one side of the lower mounting strip, and the lower fixing strap is configured as a flexible structure.

[0014] The present invention is further configured such that: a mounting frame is installed at the bottom of the lower rod, and a set of mounting blocks are respectively installed at symmetrical positions at both ends of the mounting frame; a pulley frame is rotatably connected to the bottom of each set of mounting blocks, and a pulley is rotatably installed at the bottom of the pulley frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. This device solves the problems of fixed handle height, non-adjustable angle, and poor adaptability of traditional walking aids. By setting up a retractable handle component and a rotating adjustment structure, the grip position can be flexibly adjusted according to the height and standing posture of different users, thereby providing a more comfortable and safe support effect and significantly improving ergonomic adaptability and user experience.

[0017] 2. This device solves the problems of insufficient leg support and unstable fixation in conventional walking aids. By setting up leg support components distributed vertically and flexible fixing straps, it achieves wrap-around support from the thigh to the calf, effectively preventing support displacement or detachment during use, and significantly improving the stability of the device and the rehabilitation assistance effect.

[0018] 3. This device solves the problems of poor mobility and inconvenience in moving existing walking aids. By adding a rotating pulley assembly at the bottom of the support, the entire device has a flexible rolling function, which makes it convenient for users to move freely indoors or on flat ground, meeting various needs for rehabilitation training or daily walking assistance.
