Abstract

The invention comprises a door attaching apparatus for positioning and aligning a door for attachment to a doorway. The apparatus has a mobile frame adapted to be moved upon a surface. The mobile frame has a first frame. The first frame is movably mounted to the mobile frame to move upward and downward and forward and rearward relative to the mobile frame with a door mounted thereon. A second frame is pivotably mounted to the mobile frame behind the first frame and is handle operated to move forward and rearward on the mobile frame and to engage the first frame to cause the first frame and door thereon to move forward and rearward with the second frame to align the door in a doorway in one direction for attachment of the door to the doorways. A handle operated cam mechanism is mounted between the first and second frames to cam the first frame and thereby the door upward and downward on the mobile frame align the door in another direction for its attachment to the doorway . A ground engaging mechanism is mounted to the mobile frame to engage the ground to provide additional support for the apparatus.

  1. 1
    A door attaching apparatus comprising a mobile main frame adapted to be moved upon a surface, a first upward extending frame for supporting door thereon, said first upward extending frame lying a lower edge movably mounted to the main mobile frame at the forward portions of the main mobile frame to move upward and downward and forward and rearward relative to said mobile frame, a second upward extending frame having a lower edge pivotably mounted to the main mobile frame behind the first frame to move forward and rearward relative to said mobile frame, a guideway mechanism having two cooperating channels slidably connected together with one of said channels pivotally mounted to the first frame and the other channel attached to the second frame whereby the first frame may slide upward by its channel sliding upward in the second channel relative to the second frame and mobile frame, a cam mounted on said first frame, a first handle operating said cam to engage said second frame to cam said first frame upward and downward relative to the second frame and relative to said mobile frame;a lever rod means connecting said second frame to said mobile frame, said lever rod means having a second handle to operate said lever rod means to lever said second frame forward and rearward and through said sliding connection to said first frame simultaneously lever said first frame forward and rearward;a ground engaging plate movably mounted on said mobile frame and movable in response to said second handle means to move downward to engage the surface beneath the mobile frame when said second handle means levers said first and second frames forward to provide ground stabilization for said apparatus.
  2. 2
    A door attaching apparatus comprising a mobile frame having a first upward and second upward positioned frame each movably mounted on said mobile frame with said first frame forward of said second frame;guideway means connecting said first and second frame in upward and downward relation with raising and lower means to raise and lower said first frame, relative to said second frame in said guideway and relative to said mobile frame;said first frame having means to support and grasp a door thereon;forward and rearward moving means on said mobile frame to move said first and second frames forward to place said first frame with the door thereon in an upright position;whereby the door may be placed in a supporting position on said first frame and grasped by said first frame, and rolled on the mobile frame to an upright doorway, and the door may be moved forward in the doorway on the mobile frame into upright position relative to the doorway, and the raising and lower means may be operated to raise the door to a proper height in the doorway for attachment of the door in the doorway while in said upright it position in the doorway.

    Broadest claimClaim Score 55, average(NHIP)A door attaching apparatus comprising a mobile frame, first upward and second upward frame positioned on said mobile frame, said first frame being movably mounted relative to said mobile frame upward and downward and forward and rearward, said second frame being movably mounted to said mobile frame to move forward and rearward, guideway means connecting said first and second frames in upward and downward sliding relation with means to raise and lower said first frame relative to said second frame and mobile frame on said guideway, said first frame having means to support and grasp a door thereon, means to move said first frame upward and downward relative to said second frame and mobile frame, lever rods means to lever said second frame forward and rearward, whereby a door may be placed and grasped on said first frame and moved on the mobile frame to doorway and said second frame upon being levered forward to lever said first frame forward to place the door a proper upright position in the doorway and means to raise the first frame may be operated to raise the first frame and the door thereon to a proper height in the doorway for attachment of the door to the doorway, while in said upright position in the doorway.
  4. 5
    A door attaching apparatus comprising a mobile frame adapted to be rolled along a surface, a upward extending first frame having lateral sides and a bottom and top, a flange along the bottom to receive a door along its bottom edge, lateral telescoping rods intermediate the height of the first frame and spring urged to telescope laterally toward one another, said rod having hooked outer ends to grasp a door along its lateral edges when the door bottom edge rests upon the bottom flange of the first frame, elevating mechanism on the mobile frame for the first frame centrally between the lateral sides of the first frame to raise and lower the first frame relative to the surface to place the door at a proper height for installation of the door in a doorway, adjustment means connecting the first frame to the mobile frame to rotate the first frame in the plane of the first frame and door thereon to adjust the angular relation of the door to the doorway, forward and rearward adjustment means on the mobile frame to adjust the frame and door thereon in a plane perpendicular to the plane of the first frame.
