At this time, it is preferable that the surfaces of the vertical handles 241 and 242 and the horizontal handle 250 are made of rubber or a foamed molding material to give a high sense of grip while having elasticity.

Accordingly, the user may hold the vertical handles 241 and 242 with both hands when using the foldable wheel walking aid according to the present invention, or hold the horizontal handle 250 and walk independently.

Finally, in the present invention, as shown in FIGS. 3 and 4, the seat plate 400 having both ends connected to the horizontal bars of the first side frame 110 and the second side frame 120 is additionally configured It is also possible.

Here, the seat board 400 allows the patient or the elderly to sit down and rest for a while while walking.

More specifically, the seat plate 400 is also formed by laminating a cushion material on a plate material and covering it with a cover such as leather or artificial leather.

At this time, as shown in FIG. 14 on the bottom surface of the seat plate 400, arc-shaped hooks 410 are provided at both ends, so that the seat plate 400 is attached to the first side frame 110 and the second side frame 110 when in use. When placed on the middle horizontal bar of the frame 120, the seat plate 400 is supported by the middle horizontal bar of the first side frame 110 and the second side frame 120.

In this state, the hook 410 of the seat plate 400 effectively prevents the seat plate 400 from being separated from the horizontal bar of the first side frame 110 or the second side frame 120 by itself. will be able to sit on the seat and rest stably.

Additionally, when the seat plate 400 is not in use by using the hook 410, the seat plate 400 may be placed across the horizontal bar of the first side frame 110 or the second side frame 120.

Therefore, the foldable wheeled walking aid of the present invention configured as described above increases the convenience of storage and transportation by allowing the wheeled walking aid to be folded, while connecting both frames with mutually independent cross-shaped members to prevent folding during use. In particular, it is an invention with an excellent advantage that it can be used stably by greatly improving structural rigidity, thereby maximizing market competitiveness and marketability of the product.
