Abstract
The keyboard of a musical instrument comprises a number of keys (1) which are arranged on a fixed carrier (8) and each depressible by a predetermined amount against a return spring assembly (17). Each such assembly comprises an element, e.g. a U-shaped spring member (17a,b,a) with longitudinally spaced sides (17a) initially at right angles to the upper key surface (3) and with their lower ends connected via a strip (19) downwardly convexly curved through the spring action of the sides (17a). The longitudinal centre of the strip (or leaf spring) rests on the carrier (8) via a transverse shaft (20) which supports the strips of the respective keys. The principle is based on having two longitudinally spaced key support points (i.e. ends of the strip) on a horizontal line at a level above a central fixed support point shaft which is pref. adjustable in height via a rotatable eccentric (24) to vary touch. Alternative embodiments are described and illustrated.
