Abstract A pivotable dolly for securedly holding a heavy rectangular member, such as a door, by one edge to permit the transportation, preparation and final attachment of the member in its intented position. The dolly includes an elongated member, clamps fixed to the elongated member to releasably hold the rectangular member by its edge, handles for supporting the dolly when the elongated member is positioned horizontally, and a pair of wheels for permitting the rolling and pivoting of the dolly. When the dolly is pivoted to a horizontal position, the rectangular member being held can be vertically adjusted to properly align the rectangular member for attachment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A pivotable dolly for securedly holding a heavy rectangular member by one edge comprising: an elongated member; means fixed to said elongated member for releasably holding the rectangular member with the held edge of the rectangular member substantially parallel to said elongated member; roller means attached to one end of said elongated member for permitting the rolling of the dolly and the pivoting of the elongated member between horizontal and vertical positions, said elongated member holding the lower surface of the rectangular member at a selected level when said elongated member is in a vertical position; and means for steadily supporting said elongated member when said elongated member is in the horizontal position, said means including a first handle secured to said elongated member, said first handle including portions projecting outwardly from said elongated member opposite to said holding means and a second handle secured to said elongated member proximate to said rolling means, said second handle including portions projecting outwardly from said elongated member opposite to said holding means and beyond said roller means.
Claim 2
Dependent Claim
175 words
A pivotable dolly for securedly holding a heavy rectangular member by one edge comprising: an elongated member; means fixed to said elongated member for releasably holding the rectangular member with the held edge of the rectangular member substantially parallel to said elongated member; roller means attached to one end of said elongated member for permitting the rolling of the dolly and the pivoting of the elongated member between horizontal and vertical positions, said elongated member holding the lower surface of the rectangular member at a selected level when said elongated member is in a vertical position; and means for steadily supporting said elongated member when said elongated member is in the horizontal position, said means including a first handle secured to said elongated member, said first handle including portions projecting outwardly from said elongated member opposite to said holding means and a second handle secured to said elongated member proximate to said rolling means, said second handle including portions projecting outwardly from said elongated member opposite to said holding means and beyond said roller means.
Claim 3
Dependent Claim
49 words
The dolly of claim 1 wherein said holding means comprises a bottom bracket secured to said elongated member proximate to said roller means and a top bracket secured to said elongated member above said bottom bracket, said top bracket including a clamping means for releasably grasping the rectangular member.
Claim 4
Dependent Claim
43 words
The dolly of claim 2 wherein said clamping means of said top bracket includes a first elongated finger and a second elongated finger, said elongated fingers being selectively moveable relative to one another to permit the clamping and unclamping of the rectangular member.
Claim 5
Dependent Claim
