b. a top, having a downward facing side, an upward facing side, a center, and an outer perimeter;
c. wherein said top is rotatably attached to said outer casing;
d. a lock, movable between a first position proximate said center of said outer casing and a second position distal to said center of said outer casing;
e. a ring gear descending downward from said top, said ring gear having a plurality of teeth separated by a plurality of notches; and
f. a pawl on said lock, said pawl configured to slide into and engage one of said notches on said ring gear.
2. A pedestal as recited in claim 1 , wherein:
a. said outer casing includes a lock receiver; and
b. said lock is slidably mounted within said lock receiver.
3. A pedestal as recited in claim 1 , wherein said pawl includes a tapered portion positioned to first engage said one of said notches.
4. A pedestal as recited in claim 3 , wherein when said lock is in said second position said lock is wedged tightly between said outer casing and said ring gear.
5. A pedestal as recited in claim 1 , wherein:
a. said ring gear has an inner perimeter; and
b. said lock has a stop configured to bear against said inner perimeter of said ring gear when said lock is in said second position.
6. A pedestal as recited in claim 1 , wherein said lock has a grip positioned on the outside of said outer casing.
7. A pedestal as recited in claim 6 , wherein said grip has an inward facing surface configured to bear against said outer wall of said outer casing when said lock is in said first position.
8. A pedestal as recited in claim 5 , wherein said lock has a grip positioned on the outside of said outer casing.
9. A pedestal as recited in claim 8 , wherein said grip has an inward facing surface configured to bear against said outer wall of said outer casing when said lock is in said first position.
10. A pedestal, comprising:
a. an outer casing, having a downward facing side, an upward facing side, a center, and an outer wall;
b. a top, having a disk and a ring gear descending downward from said disk;
c. wherein said ring gear includes a plurality of teeth separated by a plurality of notches;
d. a circular ball bearing case attached to said top, said ball bearing case having a plurality of ball bearings facing downward;
e. wherein said top is rotatably attached to said outer casing with said upward facing side of said outer casing facing said ball bearing case;
f. a lock, movable between a first position proximate said center of said outer casing and a second position distal to said center of said outer casing;
g. wherein when said lock is in said first position said top is free to rotate with respect to said outer casing; and
h. wherein when said lock is in said second position said lock engages said ring gear, thereby rotatably securing said top with respect to said outer casing.
11. A pedestal as recited in claim 10 , wherein:
a. said outer casing includes a lock receiver; and
b. said lock is slidably mounted within said lock receiver.
12. A pedestal as recited in claim 10 , further comprising a bearing race in said upward facing side of said outer casing, said bearing race being sized and positioned to receive said plurality of ball bearings within said ball bearing case.
13. A pedestal as recited in claim 10 , wherein said lock includes a pawl positioned to slide into one of said notches when said lock is moved from said first position to said second position.
14. A pedestal as recited in claim 13 , wherein said pawl includes a tapered portion positioned to first engage said one of said notches.
15. A pedestal as recited in claim 14 , wherein when said lock is in said second position said lock is wedged tightly between said outer casing and said ring gear.
16. A pedestal as recited in claim 10 , wherein:
a. said ring gear has an inner perimeter; and
b. said lock has a stop configured to bear against said inner perimeter of said ring gear when said lock is in said second position.
17. A pedestal as recited in claim 10 , wherein said lock has a grip positioned on the outside of said outer casing.
18. A pedestal as recited in claim 17 , wherein said grip has an inward facing surface configured to bear against said outer wall of said outer casing when said lock is in said first position.
19. A pedestal as recited in claim 15 , wherein said lock has a grip positioned on the outside of said outer casing.
20. A pedestal as recited in claim 16 , wherein said pawl includes a tapered portion positioned to first engage said one of said notches.
