Projeto de uma cadeira elevatória de baixo custo para escadas

Abstract

The growing urban sprawl, focused on the verticalization of cities, requires equal growth in the provision of accessibility solutions for people with disabilities and reduced mobility conditions. Ensuring the existence of equipment that adapts the environment to the individual is to consolidate the right to free movement, offering broad social inclusion. In relation to the Brazilian scenario, the main obstacle to the diffusion of accessibility equipment is the acquisition cost. This work brings the design of a low-cost chair for straight stairs, with only one elevation, presenting an ability to have speed of travel superior to commercial products. For this, we analyze experiments in commercial solutions and ABNT standards inherent in accessibility. Based on standards and comparisons with commercial equipment, it was possible to define the main components for the project, such as drive, frequency inverter, controller board and bluetooth communication module. The result was a definition of a possible project to transport people with limited mobility on stairs. The cost of the initial prototype is less than R$ 2,000.00, approximately 10 times lower than the cost of a commercial product. Therefore, in this work, in addition to consolidating acquired knowledge, we sought to develop a study in the area of accessibility that allows a fairer treatment for people with physical disabilities and motor limitations.
