Description

Technical Field

[0001] The utility model relates to the technical field of elderly care, in particular to a walking-assisting device for preventing the elderly from falling. Background Art

[0002] When people with single-leg injuries are doing lower limb flexibility exercises, canes or underarm crutches are often used to assist walking. However, for elderly people with single-leg injuries who are in urgent need of rehabilitation exercises, it is not safe to use traditional single-leg supported canes or underarm crutches because the single-leg canes or underarm crutches have limited support points on the ground, resulting in weak support stability. Therefore, elderly people with single-leg injuries often use walking aids with rollers and multiple support points to assist walking. Walking aids with multiple support points have better stability than single-leg supported walking aids.

[0003] However, although the existing multi-point support walking aid device can prevent the elderly from falling to a certain extent, it requires the user to walk on both feet, and people with single-foot injuries, especially the elderly, find it difficult to walk on both feet for a long time. Therefore, the existing multi-point support walking aid device is not convenient for people with single-foot injuries to walk alternately on one or both feet during rehabilitation training, and is not conducive to continuous rehabilitation training for people with single-foot injuries. For this reason, we propose an anti-fall walking aid device that can enable elderly people with single-foot injuries to walk alternately on one or both feet. Utility Model Content

The lower ends of the symmetrical "X" frames are connected to pushing assemblies through bent rods, and an axle passes through the lower end of the "X" frame. A traction rod is fixed with bolts on the surface of the axle, and one side of the traction rod is connected to the rear wheel through a bearing. A positioning rod is welded between one side of the "X" frame and the arc connecting rod, and a first connecting hole group is penetrated through the side of the positioning rod, and a second connecting hole group is penetrated through the side of the traction rod.

[0006] As a further solution of the utility model: the cross-sectional diameter of the gripping area is smaller than the cross-sectional diameter of the crossbar, and the surface of the gripping area is glued with an anti-slip cover, so that the gripping area is convenient for the user to hold with his hand, so that the walking aid device can be used as a multi-point supported crutch, avoiding standing on one injured foot for a long time and preventing elderly people with one injured foot from falling.

[0007] As a further solution of the utility model: the pushing assembly includes a direction rod, and handrail rods are respectively inserted through both ends of the direction rod and clamped thereon. A locking nut is threadedly connected at the connection between the handrail rod and the direction rod. By loosening the locking nut, the lower end of the handrail rod can be extended and retracted inside the direction rod to adjust the height of the handrail rod to accommodate users of different heights.

[0008] As a further solution of the utility model: a pushing part is coaxially connected to the middle of the handrail, and the friction coefficient of the surface of the pushing part is not less than 0.5, so as to avoid slipping when the hand and the pushing part are held.

[0009] As a further solution of the utility model: a reverse brake mechanism is connected to the surface of the pushing part to brake the rear wheel.

[0010] As a further solution of the utility model: the first connecting hole group includes at least two first connecting holes, and the side of the second connecting hole group is provided with a second connecting hole corresponding to the coaxial center of the first connecting holes.

At this time, the front wheel and the two ends of the U-shaped frame are supported, so that the walking aid device can be used as a multi-point support crutch to avoid the injured lower limb from being forced to walk for a long time. When the tangent plane of the bottom surface of the rear wheel is adjusted to be coplanar with the tangent plane of the bottom surface of the front wheel, the front wheel and the rear wheel can roll synchronously for walking, which can be used as a rehabilitation exercise for the injured lower limb for users with single-leg injuries, and is convenient for people with single-leg injuries to walk alternately with one or both feet during the rehabilitation exercise.

[0014] 2. The utility model connects the anti-slip cover by gluing the surface of the gripping area. On the one hand, the gripping area is convenient for the user to hold, so that the walking aid can be used as a crutch with multi-point support, avoiding standing on one injured foot for a long time and preventing elderly people with one injured foot from falling. At the same time, the anti-slip cover can strengthen the static friction between the hand and the gripping area, improve the gripping stability, and prevent the hand from slipping.
