Abstract

A key extender includes an elongated member, e.g., a deformable metal rod, having a first end portion secured to a contact member, e.g., a circular disc having a contact area greater than the available touch plate surface area of the key. An opposite second end portion of the elongated member is secured to a first part of a fastening arrangement, with the other part of the fastening arrangement on a key of a keyboard. Mounting an extender on each of the keys of a keyboard and shaping the metal rod to position the discs adjacent to and spaced from one another allows a disabled person to depress the closely adjacent keys of the keyboard, e.g. and not limited to, the keys of a piano or keys of a typewriter.

Claims
