<p>The invention comprises a door attaching apparatus (20) for positioning and aligning a door (24) for attachment to a doorway. The apparatus (20) has a mobile frame (21) adapted to be moved upon a surface. The mobile frame has a first frame (22). The first frame (22) is movably mounted to the mobile frame (21) to move upward and downward and forward and rearward relative to the mobile frame (21) with a door mounted thereon. A second frame (23) is pivotally mounted to the mobile frame (21) behind the first frame (22) and is handle-operated to move forward and rearward on the mobile frame (21) and to engage the first frame (22) to cause the first frame (22) and door (24) thereon to move forward and rearward with the second frame (23) to align the door in a doorway in one direction for attachment of the door (24) to the doorway. A handle-operated cam mechanism (54) is mounted between the first (22) and second (23) frames to cam the first frame (22) and thereby the door (24) upward and downward on the mobile frame (21) to align the door (24) in another direction for its attachment to the doorway. A ground engaging mechanism (33) is mounted to the mobile frame to engage the ground to provide additional support for the apparatus (20).</p> |
