Title: Toilet for the disabled
IPC: E03D9/08
Filed: 1989-06-26
Abstract: The toilet for the disabled is an ingenious system which fits onto existing appliances and provides essential modifications which allow any user, disabled or otherwise, to answer either call of nature without difficulty, and women to carry out their personal hygiene, without the inconvenience of unpleasant smells and the awkward, always imperfect, often inadequate action of wiping oneself... The user simply sits on the new toilet seat (made of cellular foam) and the entire operation of washing, cleaning and drying is automatically commenced by: - 1) a whistle or voice command; or - 2) a push button operated by the user; or - 3) a pedal operated by the user. This operation completed, the user emerges clean and fresh. Using the "toilet for the disabled" becomes a pleasure for everyone.
