A Stairlifts is a mechanical device that lifts people up and down stairs, usually individuals with impairments. [1] A rail is attached to the stair treads for adequately wide steps. The rail is attached to a chair or a lifting platform. A person sits in the chair or platform and is lifted up or down the stairs by the chair moving along the rail.
They are now commonly used by the elderly, those who are prone to falling, and the disabled who are unable to securely travel steps.
C.C. Crispen, a Pennsylvania entrepreneur, invented a mechanism for his ailing friend to travel from floor to floor in the 1920s. Crispen's concept was to create a Stairlifts. He designed the first inclining chair prototype as a self-taught engineer. It was dubbed the Inclin-ator by him. [4] Prior to this, Royal Tunbridge Wells' Frederick Muffett designed and patented the "An Invalid Chair with Tramway for Usage on Staircases." However, in 2009, TV historian Doctor David Starkey discovered proof in a list of King Henry VIII's possessions suggesting the monarch invented the first stairlift.
