Description

A multifunctional crutch

technical field

The invention relates to the technical field of old-aid machinery, in particular to a multifunctional crutch.

Background technique

The aging of the population in my country is accelerating and deepening, the aging population is increasing, and the demand for elderly aids is also increasing. The elderly not only need crutches to provide support when they go out for daily activities, but also need to adapt to various problems encountered during travel. At present, the design and application of folding multi-functional crutches at home and abroad are not very extensive, and most of them are based on single-chip microcomputers. The research on functional intelligent crutches, or adding lighting, radio, storage compartments and other functions to the crutches, has less design on the structure of the crutches.

After searching the existing technical documents, it was found that Zhang Xin, Bai Tao, Li Chunxue and others of Shenyang Institute of Technology published the structure and function design of a multifunctional crutch in "Southern Agricultural Machinery". The bottom of the multifunctional crutch is composed of a pair of triangular climbing ladders The bottom of the multi-functional crutch is composed of a pair of triangular ladder roller devices, and there is a foldable seat integrated with the crutch on the side. This product can solve the problems of the elderly going up the stairs and resting when they are tired. It provides a solution to facilitate the daily travel of the elderly, but it cannot provide better help for the elderly who can walk again.

It can be seen that there are still many unresolved specific solutions to the practical problems that need to be dealt with in its practical application (a multi-functional crutch with strong practicality).
