ERGONOMIC LITTER DEVICE

1 . A litter device comprising:

a) a base;

b) a waste bin removably located within the base;

c) a chamber with an entry opening, wherein the chamber is configured to retain a litter, is rotatably supported by the base, and configured to come into fluid communication with the waste bin; and

d) a drive source configured to rotate the chamber during a cleaning cycle of the litter device, wherein the drive source is manual.

2 - 20 . (canceled)

21 . The litter device of claim 1 , wherein the drive source transfers a manually applied mechanical force to the chamber such as to rotate the chamber.

22 . The litter device of claim 21 , wherein the drive source includes a hand crank.

23 . The litter device of claim 22 , wherein the drive source is in rotatable communication with one or more gears.

24 . The litter device of claim 23 , wherein the one or more gears are engaged with a track.

25 . The litter device of claim 24 , wherein the track encircles an outside wall of the chamber.

26 . The litter device of claim 25 , wherein the track lies in a track plane which is offset from both a horizontal plane and vertical plane.

27 . The litter device of claim 25 , wherein the track includes a gear, teeth, or both.

28 . The litter device of claim 27 , wherein the hand crank is movably affixed to the base and extends outward away from an interior of the base.

29 . The litter device of claim 28 , wherein the hand crank is in rotatable communication with and/or includes a drive shaft.

30 . The litter device of claim 29 , wherein the drive shaft is in rotatable communication with the one or more gears.

31 . The litter device of claim 30 , wherein the one or more gears includes one or more pinion gears engaged with the track.

32 . The litter device of claim 31 , wherein the one or more gears includes a plurality of gears, and one or more additional gears are located between the one or more pinion gears and the drive shaft.

33 . The litter device of claim 30 , wherein rotation of the hand crank transfers torque to the one or more gears which then transfer torque to the track and result in rotation of the chamber such that a waste opening of the chamber aligns with the waste bin.

34 . A litter device comprising:

a) a base;

b) a waste bin removably located within the base;

c) a chamber with an entry opening, wherein the chamber is configured to retain a litter, is rotatably supported by the base, and configured to come into fluid communication with the waste bin;

d) a track which encircles an outside wall of the chamber;

e) a drive source configured to rotate the chamber during a cleaning cycle of the litter device, wherein the drive source is manual and free of requiring an electronic power source, wherein the drives source includes:

i) a hand crank moveably affixed to the base and extending outward away from an interior of the base;

ii) one or more gears in rotatable communication with both the hand crank and the track; and

iii) a drive shaft between the hand crank and the one or more gears.

35 . The litter device of claim 34 , wherein the track lies in a track plane which is offset from both a horizontal plane and vertical plane.

36 . The litter device of claim 35 , wherein the one or more gears includes one or more pinion gears engaged with the track.

37 . The litter device of claim 36 , wherein the one or more gears includes a plurality of gears, and one or more additional gears are located between the one or more pinion gears and the drive shaft.

38 . The litter device of claim 37 , wherein the one or more additional gears include one or more bevel gears.

39 . The litter device of claim 38 , wherein the one or more additional gears include one or more stepped gears.
