Abstract
A door liftinng device for lifting a door into an installation position. The door lifting device includes a lever member being longitudinal, curved from a first end to near a second end which is curved away from the top side of the lever member; and also includes a fulcrum member being semi-circular shaped and being securely attached to the bottom side of the lever member near the first end thereof; and further includes a door abutment member securely attached to the top side of the lever member and being disposed closer to the first end than is the fulcrum member so that a door can be mounted between the door abutment member and the first end of the lever member.
Claims9
A door lifting device comprising:
- a lever member having a first end, a second end, a top side and a bottom side, and being longitudinally curved from said first end to near said second end;
- a fulcrum member securely attached to said bottom side and spaced from said first end of said lever member and being adapted to support said lever member;
- a door abutment member securely attached to said top side near said first end of said lever member;
- wherein a distance between said fulcrum member and said door abutment member is substantially equal to a distance between said door abutment member and said first end of said lever member.
A door lifting device comprising:
- a lever member having a first end, a second end, a top side and a bottom side, and being, longitudinally curved from said first end to near said second end, said lever member being downwardly curved from said first and second ends thereof, said second end being curved away from said top side of said lever member to limit the height said first end of said lever member can be raised, said lever member having a length of approximately 18 to 20 inches and a width of approximately 2 inches;
- a fulcrum member securely attached to said bottom side and spaced from said first end of said lever member and being adapted to support said lever member, said fulcrum member being semi-circular shaped and being adapted to rest upon a ground surface;
- a door abutment member securely attached to said top side near said first end of said lever member, said door abutment member being spaced closer to said first end than is said fulcrum member, said space between said door abutment member and said first end being adapted to support a bottom of a door thereupon;
- and
- wherein a distance between said fulcrum member and said door abutment member is substantially equal to a distance between said door abutment member and said first end of said lever member.
A door lifting device comprising:
- a lever member having a first end, a second end, a top side and a bottom side, and being longitudinally curved from said first end to near said second end;
- a fulcrum member securely attached to said bottom side and spaced from said first end of said lever member and being adapted to support said lever member;
- a door abutment member securely attached to said top side near said first end of said lever member;
- wherein said door abutment member is located approximately at a midpoint between said fulcrum member and said first end of said lever member.
