formed with a height, a depth, and a width as well as of a flexible
material that provides the deflection needed to release right gear
tooth 1416 from the valley defined between the pair of teeth of
right teeth 1202. An illustrative flexible material may be a 1/2
hard stainless steel, a plastic material, etc. For example, gear
tooth body 1402 may be molded of a polyoxymethylene material due to
its ability to snap on and flex without breaking and with a memory
to return to an original position. Gear tooth stop 1408 is
configured to stop a deflection of gear tooth body 1402 when a
maximum deflection in the direction away from right teeth 1202 is
reached. For example, gear tooth stop 1408 is formed with a height,
a depth, and a width that provide sufficient rigidity to stop the
deflection of gear tooth body 1402 before gear tooth body 1402
separates from gear tooth connector body 1406.
[0081] Gear tooth body 1402 and right gear tooth head 1404 act as a
spring lever. The consumer can push right gear tooth head 1404 away
from right teeth 1202 to disengage, rotate, and re-engage right
gear tooth 1416 with a different valley to define a new angled
position of gear tooth body 1402 relative to hub body 1201.
[0082] In the illustrative embodiment, right gear tooth device 1400
and left gear tooth device 1700 are mirror images of each other
when mounted to gear hub 1200 relative to a vertical plane through

frame 400 parallel to the plurality of tine arms 424. Similarly,
left gear tooth device 1700 may include gear tooth body 1402, left
gear tooth head 1704, gear tooth connector body 1406, gear tooth
stop 1408, gear tooth stop body 1410, gear tooth stop brace 1412,
gear tooth tine aperture wall 1414, left gear tooth 1716, contact
face 1500, and mounting prong 1502. Right gear tooth head 1404
extends to the right of gear tooth body 1402; whereas, left gear
tooth head 1704 extends to the left of gear tooth body 1402. Right
gear tooth 1416 is mounted on a right edge of gear tooth body 1402;
whereas, left gear tooth 1716 is mounted on a left edge of gear
tooth body 1402. In the illustrative embodiment, when right gear
tooth head 1404 is mounted to gear hub 1200 and right gear tooth
1416 is positioned adjacent center tooth 1302 of gear hub 1200,
right gear tooth 1416 is positioned within a first valley of right
teeth 1202 that is closest to center tooth 1302. In the
illustrative embodiment, when left gear tooth head 1704 is mounted
to gear hub 1200 and left gear tooth 1716 is positioned adjacent
center tooth 1302 of gear hub 1200, left gear tooth 1716 is
positioned within a first valley of left teeth 1300 that is closest
to center tooth 1302.
[0083] In an alternative embodiment, right gear tooth device 1400
and left gear tooth device 1700 may be identical. For example, a
position of right gear tooth 1416 and left gear tooth 1716 may be
adjusted and/or a circumferential arc length of center tooth 1302
may be adjusted.
[0084] The components of right gear tooth device 1400 and left gear
tooth device 1700 may be formed of one or more materials, such as
metal, glass, and/or plastic having a sufficient strength and
rigidity to provide the illustrated and/or described function of
