Description

Technical Field

[0001] The utility model relates to the technical field of walking assistance, in particular to a walking anti-fall device for elderly people. Background Art

[0002] As the elderly age, their limbs will gradually become weak and frail. In order to improve this phenomenon, the elderly need to exercise walking regularly. In this process, they need to use walking anti-fall devices such as walkers to assist.

[0003] The traditional anti-fall device for elderly people's walking is relatively simple in structure, requiring the elderly to use their arms to support and push the device to walk. However, this anti-fall device has certain disadvantages. It lacks a back support structure. When the elderly take a break, once the body tilts backward, it will directly lead to a fall, and even cause lighter anti-fall devices such as walkers to fall together. It is not safe to use. Therefore, we propose a anti-fall device for elderly people's walking. Utility Model Content
