Abstract

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 83 words
The dolly of claim 2 wherein said clamping means includes a C-clamp having two arms, a clamp bolt and a pivotable end member at one end of the clamp bolt; a first elongated finger fixed to one arm of said C-clamp; and a second elongated finger fixed to the pivotable end member of said C-clamp, said second elongated finger including a notch which accepts a portion of said C-clamp and thereby prevents the rotation of said second member with respect to said C-clamp.
Claim 6
Dependent Claim 31 words
The dolly of claim 3 wherein said bottom bracket includes side flanges for containing the rectangular member and a bottom surface for receiving and supporting the bottom of the rectangular member.
Claim 7
Dependent Claim 19 words
The dolly of claim 3 wherein said bottom bracket includes a clamping means for releasably grasping the rectangular member.
Claim 8
Dependent Claim 23 words
The dolly of claim 1 wherein said roller means comprises a pair of wheels rotatable about an axle interconnected to said elongated member.
Claim 9
Dependent Claim 47 words
The dolly of claim 1 wherein said roller means is slideable relative to said elongated member in a direction parallel to said elongated member, and further comprising means for effecting the sliding of said roller means relative to said elongated member to vertically adjust the rectangular member.
Claim 10
Dependent Claim 13 words
The dolly of claim 1 wherein said effecting means includes a hydraulic jack.
Claim 11
Dependent Claim 56 words
The dolly of claim 8 wherein said effecting means includes a lift handle rotatably positioned on said elongated member, a pair of spider gears interconnected with said lift handle, an elongated bolt fixed to one of said spider gears, a threaded nut fixed to said roller, said elongated bolt being threadily engaged in said threaded nut.
Claim 12
Dependent Claim 216 words
A pivotable dolly for securedly holding a door to permit the preparation, transportation and hanging of the door comprising: an elongated member; a top bracket fixed to said elongated member, said top bracket including clamping means for releasably holding the door with an edge of the door substantially parallel to said elongated member; a bottom bracket fixed to said elongated member for engaging and steadying the door; a handle fixed to said elongated member opposite to said top bracket for steadily supporting said elongated member and the door when in a horizontal position; roller means, slidable relative to said elongated member and said brackets in a direction parallel to said elongated member, for permitting the rolling of the dolly and the pivoting of the elongated member between horizontal and vertical positions, said roller means including a support slidable within said elongated member; and means for effecting the sliding of said roller means relative to said elongated member to vertically adjust the door, said means including a lift handle rotatably positioned on said elongated member, a pair of spider gears interconnected with said lift handle, an elongated bolt fixed to one of said spider gears, and a threaded nut fixed to said support of said roller means, said elongated bolt being threadily engaged in said threaded nut.
Claim 13
Dependent Claim 216 words
A pivotable dolly for securedly holding a door to permit the preparation, transportation and hanging of the door comprising: an elongated member; a top bracket fixed to said elongated member, said top bracket including clamping means for releasably holding the door with an edge of the door substantially parallel to said elongated member; a bottom bracket fixed to said elongated member for engaging and steadying the door; a handle fixed to said elongated member opposite to said top bracket for steadily supporting said elongated member and the door when in a horizontal position; roller means, slidable relative to said elongated member and said brackets in a direction parallel to said elongated member, for permitting the rolling of the dolly and the pivoting of the elongated member between horizontal and vertical positions, said roller means including a support slidable within said elongated member; and means for effecting the sliding of said roller means relative to said elongated member to vertically adjust the door, said means including a lift handle rotatably positioned on said elongated member, a pair of spider gears interconnected with said lift handle, an elongated bolt fixed to one of said spider gears, and a threaded nut fixed to said support of said roller means, said elongated bolt being threadily engaged in said threaded nut.
