    Automatic Carry Fold Ladders for Attics2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Data shows that elderly people are more likely to live alone than younger people, meanwhile the percentage of elderly people with disabilities increases significantly with age. These trends and facts bring a number of issues. One of these we would like to solve is that it is difficult and dangerous for them to lift the heavy loads through ladder. Sometimes it is also very dangerous for normal people, not to mention to people with reduced mobility.

    In order to solve these issues and reduce the possibility of accident, we have come up with a new ladder used for attics that can transport the heavy loads automatically.

    As transmission part we use a rack and pinion mechanism to achieve a   smooth transport and a ratchet mechanism for stopper to avoid sudden accident drops.  The ladder also can be hidden when not using it.
