In the field of providing mobility for the elderly and disabled, the aspect of dealing with stairs continues largely unresolved. This paper focuses on presenting the development of a stair-climbing wheelchair mechanism with high single-step capability. The mechanism is based on front and rear wheel clusters connected to the base (chair) via powered linkages so as to permit both autonomous stair ascent and descent in the forward direction, and high single-step functionality for such as direct entry to and from a van. Primary considerations were inherent stability, provision of a mechanism that is physically no larger than a standard powered wheelchair, aesthetics, and being based on readily available low-cost components.
在为老年人和残疾人提供行动能力的领域中，处理楼梯的方面在很大程度上仍未得到解决。本文重点介绍了一种具有高单步跨越能力的爬楼梯轮椅机构的发展情况。该机构基于通过动力连杆连接到底座（轮椅）的前后轮组，以便能够在向前方向上自主上下楼梯，并具备诸如直接进出厢式货车等的高单步功能。主要考虑因素包括固有稳定性、提供一种在物理尺寸上不大于标准电动轮椅的机构、美观性以及基于易于获得的低成本部件。
