Abstract
803,814. Keyboard musical instruments. VEB GERAER KLAVIATURENFABRIK. Feb. 25, 1955, No. 5704/55. Drawings to Specification. Class 88 (2). The white keys have convex playing surfaces, which may be roughened. The black keys either have vertical sides or are narrower at the bottom than at the top, and may slope downwards towards the back. The front surfaces of the white keys or the black keys, or both, may be curved. The gaps between the keys in the " black-and-white " playing area at the back of the keyboard are greater than usual in order to reduce the risk of inadvertently depressing two keys simultaneously, this being achieved by narrowing the keys without increasing the overall dimensions of the keyboard.
