Abstract

A garbage disposal installation tool for installing garbage disposal units under sinks providing two degrees of height adjustment that consists of a flat base portion, a hollow cylindrical housing portion that has an operable locking system attached to the base portion, a hollow cylindrical shaft portion sliding longitudinally inside the housing portion, wherein sliding position temporarily secured and locked by the locking system, a flat top platform portion having an externally threaded rod portion extending perpendicular to the top platform, and a rotatable lever bar nut having an internally threaded center through hole with screw threads matchingly corresponding with the threaded rod portion, wherein rotation of the lever bar nut causes axial motion of the externally threaded rod portion resulting in raising and lowering of the top platform portion.

Claims

1. A garbage disposal installation tool for installing garbage disposal units under sinks that consists of a flat base portion, a hollow cylindrical housing portion having an operable locking system attached to the base portion, a hollow cylindrical shaft portion sliding longitudinally inside the housing portion, wherein sliding position temporarily secured by the locking system, a flat top platform portion having an externally threaded rod portion extending perpendicular to the top platform, the flat top platform further having a key shape recessed into the top platform wherein the key shape has an elongated channel ending at one side of the top platform and a second circular shape connected to the elongated channel, and a rotatable lever bar nut having an internally threaded center through hole with screw threads matchingly corresponding with the threaded rod portion, wherein rotation of the lever bar nut causes axial motion of the externally threaded rod portion resulting in raising and lowering of the top platform portion.

2. A garbage disposal installation tool for installing garbage disposal units under sinks, the garbage disposal installation tool comprising:

a rigid, stable and flat base portion having a flange attached in the center of an upper surface of the flat base portion, the flange providing an anchor point for a hollow cylindrical housing portion;

a hollow cylindrical housing portion having one end rigidly attached to the flange on the base portion, the cylindrical housing portion extending essentially perpendicular to the base portion, the cylindrical housing portion having an operable locking system;

a hollow cylindrical shaft portion sliding freely and snugly longitudinally inside the cylindrical housing portion, wherein sliding position is temporarily secured and locked by the locking system, the cylindrical shaft portion further having an upper bearing surface;

a rigid, stable and flat top platform portion having a flange attached to the center of a lower surface of the top platform portion, the top platform portion further having an upper supporting surface, the flat top platform further having a key shape recessed into the top platform wherein the key shape has an elongated channel ending at one side of the top platform and a second circular shape connected to the elongated channel, the flange attached to the top platform portion providing an anchor point for an elongated, externally threaded rod portion;

an elongated, externally threaded rod portion extending essentially perpendicular to the top platform from the flange of the top platform, the externally threaded rod portion disposed slidingly within the hollow cylindrical shaft portion; and

a rotatable lever bar nut having an internally threaded center through hole with inside diameter and screw threads matchingly corresponding with the threaded rod portion, the lever bar nut portion having an upper surface and a lower bearing surface, the lever bar nut portion rotatably threaded onto the externally threaded rod portion with the lower bearing surface in intimate contact with the upper bearing surface of the hollow cylindrical shaft portion, wherein rotation of the lever bar nut portion causes axial motion of the externally threaded rod portion, resulting in raising and lowering of the top platform portion.

3. The garbage disposal installation tool of claim 2 further comprising a vinyl washer positioned between the lower bearing surface of the lever bar nut portion and the upper bearing surface of the cylindrical shaft portion for friction reduction.

4. The garbage disposal installation tool of claim 2 in which the lower tip of the cylindrical shaft portion further has scale embossed to indicate height.

5. The garbage disposal installation tool of claim 2 in which the locking system further comprising a side threaded pin hole on the cylindrical housing portion and a detachable threaded knob pin, the threaded knob pin further having a bearing tip.

6. The garbage disposal installation tool of claim 5 in which the locking system further comprising a side threaded hole on the cylindrical housing portion and a detachable threaded knob pin having a cross-sectional shape and dimension matchingly to the locking holes.

7. The garbage disposal installation tool of claim 2 in which the cylindrical shaft portion further having a plurality of identical locking holes distributed longitudinally on the side.

8. The garbage disposal installation tool of claim 2 in which the cylindrical housing portion and the elongated screw portion both have lengths of between about 10 cm and about 45 cm.

9. The garbage disposal installation tool of claim 2 in which the flat base portion further comprises a center hole at the base of the hollow cylindrical housing portion.

10. The flat base portion of claim 9 in which the center hole having a depth approximately half of the thickness of the flat base portion.

11. The flat base portion of claim 9 in which the center hole having an internal diameter and threaded surface matchingly corresponding with the threaded rod portion.

12. The garbage disposal installation too of claim 2 in which the cylindrical shaft portion further has an upper tip which is knurled on an outside surface.

13. The garbage disposal installation tool of claim 2 in which the key shape accommodates and fixes the position of at least one of the following:

an utility line, waste line, drain line and power connection.

14. A garbage disposal installation tool for installing garbage disposal units under sinks that consists of a flat base portion, a hollow cylindrical housing portion having an operable locking system attached to the base portion, a hollow cylindrical shaft portion sliding longitudinally inside the housing portion, wherein sliding position temporarily secured by the locking system, a flat top platform portion having an externally threaded rod portion extending perpendicular to the top platform, the flat top platform further having a key shape recessed into the top platform, the key shape being an aperture through the to platform, wherein the key shape has an elongated channel ending at one side of the top platform and a second circular shape connected to the elongated channel, and a rotatable lever bar nut having an internally threaded center through hole with screw threads matchingly corresponding with the threaded rod portion, wherein rotation of the lever bar nut causes axial motion of the externally threaded rod portion resulting in raising and lowering of the top platform portion.
