Title: Safety piano dolly

Abstract: A piano dolly for mounting, storing, and transporting an upright piano. A pair of dollies is used with a single upright piano, each dolly having a recessed carrying arm on which are mounted an upraised support plate supported in the longitudinal direction and a second upraised support plate in the transverse direction, each support plate supporting a wheeled caster. A piano provided with a pair of such dollies is prevented from inadvertent upset in storage or in playing situations, while mobility of the piano in transport over typical floor surfaces is unaffected. The invention can alternatively be used for storing and transporting a portable organ, or a bulky article of furniture, such as a sofa, or the like.
