Abstract
Piano pedal operating device for people with disabilities, which allows for said operation by pressure exerted by the back of a user, wherein said piano comprises a first, vertical axis that may move longitudinally operated by means of the right pedal; a second, transverse axis joined to the first axis; strings operated by means of keys, designed to produce sounds; and dampers operated by the second axis, designed to prolong or extinguish the sounds produced by the strings. The device comprises a magnet attached to the first axis; an electro-permanent suction cup placed above the magnet, which it attracts in order to move the dampers away from the strings; a cable that conducts an electric current to the electro-permanent suction cup, in order to annul its attraction over the magnet, and thus bring the dampers closer to the piano strings; and a switch designed to cut the current flow.
