stair climbing wheelchair

Abstract

The invention relates to a wheelchair, a draw bar box, a barrow and a baby carriage, capable of climbing stairs. The wheelchair, the draw bar box, the barrow and the baby carriage adopt a stair climbing device including stair climbing guiding sliding plates and stair climbing slipping shoes which separately sleeve the corresponding stair climbing guiding sliding plates; during walking stairs up and down, the stair climbing slipping shoes are in contact with an intersecting line of the horizontal surface and a vertical surface of a tread; the stair climbing guiding sliding plates fixed on a barrow body or a baby carriage body (box body) slide on the stair climbing slipping shoes; besides the whole barrow body or the baby carriage body (box body) rotates by using an intersection of the tread of each of the stairs as a support; the movement of the stair climbing device is synthesized to the oblique upward movement or the oblique downward movement, and the supporting body of the barrow body or the baby carriage body (box body) transfers between the stair climbing slipping shoes and wheels, so that the barrow body or the baby carriage body (box body) continuously walks the stairs up and down, and the wheelchair, the draw bar box, the barrow and the baby carriage have the function of climbing the stairs. The wheelchair, the draw bar box, the barrow and the baby carriage disclosed by the invention have the characteristics of being excellent in the function of climbing the stairs, smooth in movement, low in impact, effortless, simple in structure, convenient to use and the like.

Description

technical field [0001] The invention relates to a human machine tool with the function of climbing stairs, in particular to a wheelchair with the function of climbing stairs. Background technique [0002] At present, there are a large number of people with disabilities among the elderly, disabled and sick in my country. These people constitute a large number of wheelchair demand groups. The huge demand has promoted the rapid development of my country's wheelchair industry in recent years.

Problems solved by technology

However, no matter whether it is an electric wheelchair or a manual wheelchair, it is difficult to go up the stairs. However, most people in China still live in multi-storey buildings without elevators.

For this reason, the stair-climbing function of wheelchairs has become an urgent problem to be solved, and relevant manufacturers have invested a lot of manpower and material resources in research and development. At present, there are many electric wheelchairs with stair-climbing functions, but they are expensive; Not ideal, there are many solutions, but the only one that is more successful is the stair-climbing wheelchair with star wheel structure. However, this type of wheelchair has great defects, such as unstable movement, large impact, and laborious, so it is rarely used and cannot be promoted.
