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.
Claims14
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.
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.
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.
