Abstract The study aims to design and build a prototype wheelchair that would follow the accessibility standards of wheel chair design (International Standards Organization, 2010) with the ability to raise or lower its seat to have easy transporting a person to a higher height such as a vehicle with the price not too different from a regular wheelchair. The Elevating wheelchair was conceptualized from the experience and ideas of the researchers imbued to the concept learned as an actual application of the theories on power screws. The mobilization of the power screw theory in this study gave way to the researchers realized the difference of the actual application in real life situation from theoretically based idea into reality. With the help of the physically skillful craftsmen of “Tahanang Walang Hagdanan, Inc.” (TWH) and the researchers’ determination to incorporate their ideas in regards to formulation of the Elevating wheelchair design which is merely a modification of the model standard wheelchair bought in the market. The primary mechanism used to elevate/lower the seat is the motorized scissor jack powered by a 12V motorcycle battery with a maximum lifting load of 1000 kg.
Introduction Wheelchairs have been a staple of physical disabilities. They are used by people with disabilities ranging from temporary partial use of their limbs, to permanent paralysis. With this wide spread use, there have been standards (United Nations Economic and Social Commission for Western Asia, 2003) enforced to provide ramps and slopes for public buildings and transportation anywhere in the world. As much as this has improved the accessibility for
