ABSTRACT:
In construction of a piano plate for an upright piano, connectors partly embedded in one body therewith serve for direct mounting of the keyboard assembly, the side boards and the action assemblies so that three closely related elements of the upright piano, i.e. the action and keyboard assemblies and the strings, should collectively relate in construction to the piano plate for their easy and accurate relative setting and adjustment in position. Undesirable influence by warp of the conventionally used back posts and hard and troublesome mechanical work in production are both totally removed.
