Description

a walking aid

The utility model relates to a walker, in particular to a walker which is easy to fold and can greatly reduce the folded volume.

Generally, patients with spinal and lower extremity lesions still have their mobility affected after surgical treatment, so they must use other auxiliary equipment to help them walk. In the past, there was a support frame with a very simple structure, which can be supported by the rehabilitation person to help them stand. When the rehabilitation person wants to walk, he must constantly lift the support frame to move forward along with the movement of his feet, so it is obviously not practical and convenient.

In order to improve the practical shortcomings of the traditional support frame structure, a walking aid that can move similar to a vehicle has been launched on the market. Its structure is shown in Figure 6. The design of the above-mentioned design, its structure is that the rear wheel frame 81 that is generally H-shaped is pivoted at the center of the front wheel frame 80 that is generally in the shape of an H, wherein the front wheel frame 80 is made of a hollow tube body, and the center of the inner side of the two straight tubes Disposition is provided with a sliding seat 87, and is formed with chute 870 on the slidable seat 87, can pass the horizontal pipe 810 of rear wheel frame 81 therethrough, and slide up and down between this chute 870.

The lower end of the front wheel frame 80 is divided into two front wheels 85, and a handle bar 82 is respectively worn in its two longitudinal ends. The two handle bars 82 are respectively provided with a brake handle 83. device, which can pull the brake line 84 after holding it tightly to control the brake (not shown) on the rear wheel frame 81.

The lower ends of the two straight pipes of the front wheel frame 80 and the center of the two straight pipes of the rear wheel frame 81 are provided with a fixed ear 801, 811, and the two opposite fixed ears 801, 811 are pivotally connected to the two ends of a connecting piece 88. The connecting piece 88 is used to support and maintain the front and rear wheel frames 80, 81 in a relatively open state.

Two straight tube lower ends of the rear wheel frame 81 are respectively provided with a rear wheel 86 in addition, to coordinate the front wheel 85 of the front wheel frame 80 for sliding.

It can be clearly seen from the above-mentioned design that its use method is mainly supported by the user on the two handlebars 82, and the support of the front and rear wheel frames 80, 81 can be used to keep the user in a standing posture. When the user walks forward At the same time, the walker can be pushed forward at the same time, and this auxiliary device can provide a more labor-saving and convenient way of use.

Although the aforementioned walking aids are more practical and convenient than traditional support frames, there are still some unsatisfactory features. For example, the walking aids are mostly designed to be folded for easy carrying and storage. In other words, its folding method is to make the lower ends of the front and rear wheel frames 80, 81 to be relatively folded with the pivot joints of the connecting piece 88 as the fulcrum, so that the connecting piece 88 is changed from a horizontal direction to a vertical direction, and the rear wheel frame 81 The horizontal tube 810 slides from the lower end of the chute 870 to the upper end.

However, the folding structure similar to the above only reduces the front and rear depth of the walker at best, but cannot greatly change its height. Therefore, its volume reduction after folding is still limited, so it still needs to be occupied no matter whether it is carried or stored. Quite a space, but not practical.

Also, two hinged and relatively foldable folding pieces are arranged between the front and rear wheel frames to keep the open state between the front and rear wheel frames.

In the above-mentioned walker: the outer sides of the upper ends of the two straight tubes of the front wheel frame can respectively form a protruding pivot piece, and a pivot hole is formed on the pivot piece for pivotal connection with the straight tube of the upper fixed frame.

The two straight pipes of the upper fixing frame are respectively formed with pivot grooves and bolt holes arranged at 90 degrees to each other at the lower end, and cooperate with the bolt posts to pivotally connect with the straight pipes of the front wheel frame.

The upper looper on the straight pipe of the upper fixed frame is provided with a set of rings for correspondingly fitting on the upper end of the straight pipe of the front wheel frame;

Furthermore, the straight pipe of the front wheel frame can form a crescent-shaped retaining edge at the inner side of the upper end of the pivot piece to stop the collar;

Moreover, the outer contour of the collar is roughly in the shape of a figure-eight.

Compared with the prior art, the utility model has obvious advantages and positive effects. From the above technical solutions, it can be seen that after the walking aid of the utility model is folded, not only its front and rear depth can be reduced, but also its height can be greatly reduced at the same time, so that its overall volume can be greatly reduced, and it is easy to carry or store.
