Resumo
Nas últimas décadas houve um grande avanço e destaque aos temas relacionados a acessibilidade para pessoas com deficiência e visando facilitar a vida destas pessoas foram criadas leis para dar suporte aos parâmetros de acessibilidade e realizada pesquisas pelo Instituto Brasileiro de Geografia e Estatística (IBGE) afim de produzir, retratar e analisar as informações das características da sociedade brasileira e de suas condições de vida. O ponto de origem do projeto está relacionado ao problema de mobilidade enfrentado por pessoas com deficiência motora que precisam de algum tipo de acessório para se movimentarem, no qual este projeto apresenta o desenvolvimento de dispositivo adaptador com tração por pedivela de bicicleta para cadeira de roda. O objetivo é desenvolver um protótipo com estudos de características ergonômicas fazendo com que aconteça o acoplamento de uma cadeira de rodas ao dispositivo de quadro de bicicleta aro 26 que realiza transmissão de torque por corrente realizada pela distância de tração entre a coroa e catraca de redução e marcha e freios na parte dianteira. O dispositivo será de simples manuseio demandando esforço físico de membros superiores, no caso os braços, com realização da movimentação no apoio de um par de pedivela. Toda a metodologia e desenvolvimento é baseada em pesquisa com referências bibliográficas visando adquirir informações e conceitos sobre o tema do projeto e garantir a compreensão das dificuldades enfrentadas por pessoas com deficiência motora. A sequência da etapa de desenvolvimento do projeto foi realizada seguindo aplicações das fases de início, planejamento, desenvolvimento, monitoração e finalização. Apresenta cálculos, analises de simulações de esforços com auxílio de programas CAD e CAE, resultados obtidos, discussões e conclusões.
In the last decades there has been a great advance and emphasis on issues related to accessibility for people with disabilities and in order to make life easier for these people, laws were created to support accessibility parameters and research was carried out by the Brazilian Institute of Geography and Statistics (IBGE) in order to produce, portray and analyze information on the characteristics of Brazilian society and its living conditions. The point of origin of the project is related to the mobility problem faced by people with motor disabilities who need some kind of accessory to move around, in which this project presents the development of an adapter device with traction by a bicycle crank to a wheelchair. The objective is to develop a prototype with studies of ergonomic characteristics, making the coupling of a wheelchair to the 26rim bicycle frame device that performs torque transmission by chain performed by the traction distance between the crown and reduction ratchet and gear and brakes at the front. The device will be simple to handle, demanding physical effort from the upper limbs, in this case the arms, with movement on the support of a pair of cranksets. The entire methodology and development is based on research with bibliographic references in order to acquire information and concepts on the subject of the project and ensure an understanding of the difficulties faced by people with motor disabilities. The sequence of the project development stage was carried out following applications from the beginning, planning, development, monitoring and completion phases. It presents calculations, analysis of effort simulations with the help of CAD and CAE programs, results obtained, discussions and conclusions.
