Description

Technical Field

[0001] The utility model relates to the field of wheelbarrows, in particular to a wheelbarrow for the elderly. Background Art

[0002] Elderly people are usually people aged 65 and above. This age range is determined based on the general life span and health status of humans. Elderly people may experience some changes in their physical and cognitive functions, which require special attention and care. The definition of elderly people may vary from country to country, but generally speaking, people aged 65 and above are considered to be entering the elderly stage.

[0003] As people age, they may become slow and unstable, so the elderly usually use a trolley to increase their safety when moving. In order to be suitable for users of different heights, the seats of existing trolleys are generally movable. However, when the elderly adjust the seats according to their leg lengths, the position of the support frame is not suitable because many elderly people have bent backs and hunchbacks. When the elderly have a large degree of back bending, the support frame is generally too high, making it inconvenient to push.

[0004] Therefore, it is necessary to provide a new elderly cart to solve the above-mentioned problems. Utility Model Content
