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.

What is claimed is: 1. A dolly for moving a piano, comprising: a base having first and second legs; a plurality of receptacles located on said base, each of said receptacles being operatively effective for receiving a caster mounted to a leg of the piano, first and second ones of said receptacles being located on said first leg and longitudinally spaced apart from one another; a plurality of roller assemblies mounted to said base and operatively effective for rolling along a surface; said second leg being pivotally coupled, at a first end thereof, to said first leg, intermediate said first and second receptacles, for rotation relative to said first leg, a third one of said receptacles being located on said second leg proximate an opposite end thereof. 2. A dolly as recited in claim 1, wherein; said first leg has a first length and said second leg has a second length; and said first and second lengths are each selectively adjustable variable lengths. 3. A dolly as recited in claim 2, further comprising: a coupling member extending between and coupling said first and second legs, said coupling member being secured to said first leg at one end thereof and coupled to said second leg via a pivot at an opposite end thereof, said second leg being rotatable about a vertical axis passing through said pivot; wherein said second selectively adjustable variable length of said second leg extends between said vertical axis and said center of said third one of said receptacles. 4. A dolly as recited in claim 3, wherein: each of said receptacles is a flanged cup. 5. A dolly as recited in claim 1, wherein: said first leg includes first and second end members and a sleeve disposed intermediate of said first and second end members, said first and second end members being adjustably telescopically engaged partially within said sleeve. 6. A dolly as recited in claim 5, wherein: said second leg includes first and second end members and a sleeve disposed intermediate of said first and second end members, said first and second end members being adiustably telescopically engaged partially within said sleeve. 7. A dolly as recited in claim 6, wherein: said first and second end members of said first leg and said outer end member of said second leg, each include a first, relatively higher, substantially horizontally extending inner portion, a second, relatively lower, substantially horizontally extending outer portion and a substantially vertically extending portion interconnecting said first and second substantially horizontally extending portions and wherein said receptacles are located on different ones of said lower portions of said end members and are upwardly facing. 8. A dolly as recited in claim 7, wherein: each of said roller assemblies is secured to said first, relatively higher, substantially horizontally extending inner portion of its respectively associated end member. 9. A dolly as recited in claim 8, wherein: each of said relatively higher, substantially horizontally extending inner portions of said end members of said first leg and said second leg are telescopically engaged with their respective associated sleeve. 10. A dolly as recited in claim 6, wherein: said first end member of said second leg is pivotally coupled, at one end thereof, to said first leg and is adjustably telescopically engaged, at the other end thereof, to said sleeve of said second leg. 11. A dolly for moving a piano comprising: a base having first and second legs, said first leg having a first substantially longitudinal axis along its length interconnecting its opposite ends, the length of said first leg measured along said first longitudinal axis being selectively adjustably variable, said second leg having a second substantially longitudinal axis along its length interconnecting its opposite ends, said second leg being pivotally coupled to said first leg at a point between the ends thereof for pivotal movement in a substantially horizontal plane relative to said first leg when said first leg is disposed in a substantially horizontal plane; a plurality of receptacles located on said base, each of said receptacles being operatively effective for receiving a caster mounted to a leg of the piano, first and second ones of said receptacles being located on said first leg and spaced apart from one another along said first longitudinal axis, a third one of said receptacles being located on said second leg; and a plurality of roller assemblies mounted to said base and operatively effective for rolling said base along an underlying surface. 12. The dolly of claim 11, wherein the length of said second leg measured along said second substantially longitudinal axis is selectively adjustably variable. 13. The dolly of claim 12, wherein: said first one of said receptacles is located on said first leg proximate one of its opposite ends and said second one of said receptacles is located on said first leg proximate the other of its opposite ends; said second leg includes a first, inner end pivotally coupled to said first leg and a second, outer end, said third one of said receptacles is located on said second leg proximate said outer end of said second leg. 14. A method of mounting a piano on a dolly, said piano having first, second and third spaced apart generally vertical legs, the lower ends of which are arranged in a generally triangular configuration in substantially the same plane, and said dolly comprising a base having first and second legs, the first leg having a first substantially longitudinal axis along its length interconnecting its opposite ends, the length of the first leg measured along the first longitudinal axis being selectively adjustably variable, and a second selectively adjustably variable length leg having a second substantially longitudinal axis along its length interconnecting its opposite ends, the second leg being pivotally coupled at its inner end to the first leg at a point between the ends thereof for pivotal movement in a substantially horizontal plane relative to the first leg when the first leg is disposed in a substantially horizontal plane, the dolly further including a plurality of receptacles, first and second ones of the receptacles being located on the first leg and spaced apart from one another along the first longitudinal axis, a third one of the receptacles being located on the outer end of the second leg, said method comprising the steps of: adjusting the length of the first dolly leg to position the receptacles thereof at a first distance substantially equal to the distance between the lower ends of the first and second piano legs, adjusting the pivot angle between the first and second legs of the dolly and adjusting the length of the second dolly leg, to collectively locate the receptacle of the second dolly leg to receive the lower end of the third piano leg when the first and second receptacles are located to receive the lower ends of the first and second piano legs, and placing the lower ends of the first, second and third piano legs in the first, second and third receptacles.
