Abstract: A shelf unit has a modular, interlocking design and eliminates the need for hardware components. The shelf unit includes first and second side pieces each including first and second rails and first, second, and third rungs extending between the first and second rails. First and second shelf-supporting connectors attach with the first rungs of the first and second side pieces and the second rungs of the first and second side pieces, respectively, via interlocking slots. A first shelf is positioned atop the first shelf-supporting connector and a second shelf is positioned atop the second shelf-supporting connector.

Abstract: A table top extension and method for increasing the table top surface area of an existing table. The table top extension includes at least first and second planar panel sections each having a first, inner peripheral edge and a second, outer peripheral edge. The first, inner peripheral edges include interlocking tongue and groove structure such that the first, inner peripheral edges can be locked together to form the table top extension having a combined table top area defined by at least the first and second planar panel sections. The second, outer peripheral edges of the first and second planar panel sections align to form an outer peripheral edge of the table top extension when the first and second panel sections are locked together with the interlocking tongue and groove structure.

Abstract: A dolly on which a grand piano can be mounted to facilitate movement thereof over a surface from one location to another, which includes a central hub shaped in the form of a miniature grand piano, two fixed length arms of equal length pivotally connected to the front of the hub at opposite corners thereof, and a fixed length rear arm having a longitudinal slot which is pivotally connected to the rear of the hub at selectively adjustable positions along the length of the slot to accommodate grand pianos having a range of different lengths.

Abstract: A dolly for moving a piano is provided and includes a base having first and second legs, with the first leg having a longitudinal centerline and the second leg being pivotally coupled to the first leg for rotation relative to the first leg. A plurality of receptacles are mounted to the base, with each of the receptacles being operatively effective for receiving a castor mounted to a leg of the piano. First and second ones of the receptacles are mounted to the first leg and spaced apart from one another along the longitudinal centerline of the first leg, with a third one of the receptacles being mounted to the second leg. A plurality of castors are mounted to the base and are operatively effective for rolling along a surface.
