Abstract
Sport, physical activity and leisure are extremely important to promote physical and mental health, promoting social inclusion for people with physical disabilities and reduced mobility. However, for many of the practices in adaptive sports, it becomes essential to use equipment with assistive technology for the insertion of the disabled person and reduced mobility into the sport environment and leisure. At the same time, Federal law 5296/04, in accordance with the standards of the ABNT (NBR 9050/2004), guarantees to all the accessibility rights. In line with these standards, the health and engineering fields have been seeking to create accessibility solutions through new assistive technologies. Disabled people that use wheelchairs who practice swimming or hydrotherapy generally need to transfer to the pool. In this there are risks to the safety of these people or even difficulties for the person who assists in the transfer. A mechanism designed to aid the transfer of people with limited mobility or physical disability to a pool is commonly called a "pool lift". This equipment usually includes an electronic transmission system with articulated movement, a base attached in the edge of the pool and a seat for the user. Before pool lifts were invented in 1980, the biggest challenge in aquatic therapy centers was simply to get people out of the water safely and easily. The development of such equipment requires challenges for researchers as they investigate new electromechanical designs and control strategies that can work on any pool architectural designs and adapt to the mobility needs of the disabled people. Challenges include fastening the elevator to the ground, transporting the elevator between storage and use, providing a orientation system to operate the elevator, providing stability to the elevator chair maintain vertical position during the movement and the incorporation of security systems. The proposal of this work is to develop a kinematic and kinetic model for a non-rotational cantilevered pool lift to evaluate its mechanical performance. The analytical model will be validated through numerical simulations with finite elements method. The work showed that the analytical model developed has a good approximation with the numerical model and can be used as a reference for the kinematic design of new transfer systems for pools.
