ABSTRACT:
A piano case or frame includes a laminated key bed and side arms joined with the bed at each end. The key bed supports the keyboard and associated portions of the piano action, and is assembled with each side arm of the frame by means of a rabbet joint. Fastening screws extending through the laminated bed into barrel nuts within each of the side arms develop significant pressure in the rabbet joints to hold the key bed and the supported keyboard in a level, undistorted position.
