Abstract

Disclosed is an improved garbage disposal jack for use in the installation and removal of sink mounted garbage disposals. The improved garbage disposal jack allows for rotation of the garbage disposal unit while maintaining the height during the installation or removal process.

Claims

1. A device to support a garbage disposal unit that allows rotation of the garbage disposal during installation comprising:

a. a base;

b. a shaft slidably interfaced to the base, the shaft having a plurality of shaft recesses;

c. a head atop the shaft to support the garbage disposal unit; and

d. a locking disc, the locking disc having a teardrop-shaped hole with a narrow area and a wide area;

e. whereby when the narrow area of the locking disc is coupled to one of the plurality of shaft recess, height of the shaft is maintained; and

f. whereby the locking disc slides horizontally to engage the shaft recess by aligning with the narrow area and disengage the shaft recess by aligning with the wide area.

2. The device to support a garbage disposal unit of claim 1, further comprising a plurality of telescoping tubes attached atop the base to aid in vertical elevation.

3. The device to support a garbage disposal unit of claim 2, further comprising a pneumatic apparatus for vertical elevation, the pneumatic apparatus comprising:

a. an air bladder inside an outermost telescoping tube, and

b. an inflation control unit attached to the air bladder by an air tube.

4. A garbage disposal jack for aid in the installation and removal of a garbage disposal unit comprising:

a. a base;

b. a plurality of hollow tubes attached to the base, the plurality of tubes comprised of an outer tube and an inner tube in telescoping relationship,

i. the outer tube having a hole through which an air tube passes,

ii. the air tube having a first end and a second end,

1. the first end being connected to an air bladder, the air bladder located inside the outer tube and beneath the inner tube,

2. the second end being connected to an inflation mechanism; and

c. a cap with a hole;

d. a locking disc situated atop the cap, the locking disc having a teardrop-shaped hole,

i. the teardrop-shaped hole having a narrow area and a wide area;

e. a shaft passing through the hole in the cap and through the teardrop-shaped hole of the locking disc, the shaft having a top end, a bottom end, and a plurality of recesses,

i. the plurality of recesses located between the bottom end and the top end of the shaft;

f. whereby when the wide area of the teardrop-shaped hole is aligned with the shaft, the locking disc is disengaged from the plurality of recesses and the shaft is permitted to move vertically; and

g. whereby the locking disc slides horizontally across the cap, locking the shaft when the narrow area of the teardrop-shaped hole engages one of the plurality of recesses.

5. The garbage disposal jack of claim 4, wherein the inflation mechanism is a squeeze pump whereby a user inflates the air bladder by hand.

6. The garbage disposal jack of claim 4, wherein the first end of the air tube terminates in a nozzle, the nozzle connected to the air bladder.

7. The garbage disposal jack of claim 4, wherein the inflation mechanism is an electric motor that inflates the air bladder.

8. The garbage disposal jack of claim 4, wherein the top end of the shaft has a plurality of support arms extending outward.

9. The garbage disposal jack of claim 8, wherein each of the support arms is terminated by a friction member.

10. The garbage disposal jack of claim 4, wherein the bottom end of the shaft has a flat, circular portion to minimize sideways movement or wobbling.

11. The garbage disposal jack of claim 10, wherein the flat, circular portion of the bottom end of the shaft is smaller in diameter than the inner tube.

12. A garbage disposal installation tool comprising:

a. a base;

b. an outer tube attached to the base;

c. an inner tube configured in telescopic relation to the outer tube;

d. a cap atop the inner tube and the outer tube, the cap having a hole through which a shaft passes;

e. the shaft having a plurality of recesses;

f. a locking disc, the locking disc;

i. resting atop the cap,

ii. having a teardrop-shaped hole, and

iii. the shaft passing through the teardrop-shaped hole,

iv. whereby the locking disc can engage and disengage the shaft but always remains surrounding the shaft; and

g. an air bladder, the air bladder

i. inside the outer tube,

ii. resting upon the base, and

iii. connected to an inflation assembly.

13. The garbage disposal installation tool of claim 12 wherein the inflation assembly comprises:

a. a nozzle,

b. an air tube having a first end and a second end, and

c. an air pump;

d. the nozzle connecting the air bladder to the first end of the air tube; and

e. the second end of the air tube connected to the air pump.

14. The garbage disposal installation tool of claim 13, wherein the inflation assembly further comprises a release valve.

15. The garbage disposal installation tool of claim 12 wherein the inflation assembly comprises an electric motor.

16. The garbage disposal installation tool of claim 15, wherein the inflation assembly further comprises a release valve.

17. The garbage disposal installation tool of claim 12, further comprising a plurality of support arms extending outward from a top of the shaft.

18. The garbage disposal installation tool of claim 17, wherein the plurality of support arms have friction members on each tip.

19. The garbage disposal installation tool of claim 17, wherein the plurality of support arms extend outwardly and perpendicularly from the top end of the shaft.
