Description

A multifunctional elderly rollator

technical field

The invention relates to the technical field of walkers, in particular to a multifunctional walker for the elderly.

Background technique

my country has gradually entered an aging society, and the rollator has become one of the tools that the elderly need in their daily lives. The rollator is a kind of life aids. The elderly can support the rollator, which is both relaxing and exercise. The structure of the ordinary rollator is complicated to operate and difficult to store, which makes the rollator take up a lot of space. At the same time, it is more troublesome to adjust the height of the handle, which increases the difficulty of using the elderly, and cannot be used for multi-purpose changes according to the use environment. .

Most of the existing walkers for the elderly only solve the problem of inconvenience for the elderly to walk. There is no place to put items. After shopping, the elderly can only lead the items by hand or hang them on the frame of the walker. Safety also affects the use of rollators. Therefore, the elderly are easily tired in the process of walking and need to sit or squat to rest, which brings great inconvenience to the travel of the elderly. Among them, the rollator only solves the problem of walking and can no longer meet the needs of the elderly. It is also necessary to add a place for storing items on the rollator. At the same time, when the elderly are not physically strong enough and need to rest, they can sit down conveniently and safely. Roller rolls forward.
