a food processing tool positioned in the processing chamber and driven by the motor to rotate about a central axis, the food processing tool including a hub defining the central axis and a pair of adjustable blades extending outwardly from the hub, each adjustable blade having a cutting edge formed thereon, and
an adjustment assembly including a lever extending outwardly from the base, the lever being moveable relative to the base and operable to pivot each adjustable blade while the food processing tool is rotated about the central axis between a plurality of positions including (i) a first position in which each adjustable blade extends substantially parallel to a bottom surface of the removable bowl, and (ii) a second position in which each adjustable blade extends substantially orthogonal to the bottom surface of the removable bowl.
2. The food processing device of claim 1 , wherein the food processing tool includes a shaft that is positioned in the hub and is coupled to the adjustable blades, the shaft being movable vertically relative to the hub between (i) a raised position in which the adjustable blades are in the first position and (ii) a lowered position in which the adjustable blades are in the second position.
3. The food processing device of claim 2 , wherein the adjustment assembly further includes an adaptor having an upper end coupled to the shaft of the food processing tool and a lower end coupled to the base, wherein movement of the lever relative to the base causes vertical movement of the adaptor and the shaft of the food processing tool.
4. The food processing device of claim 3 , wherein the adaptor includes an upper plate coupled to the food processing tool and a lower sleeve pivotally coupled to the base.
5. The food processing device of claim 4 , wherein the upper plate includes a first plurality of teeth, and the lower sleeve has a second plurality of teeth formed thereon, the second plurality of teeth being interdigitated with the first plurality of teeth.
6. The food processing device of claim 4 , wherein:
movement of the lever in a first direction relative to the base causes (i) the adaptor to move downward and (ii) the shaft to move from the raised position to the lowered position, and
movement of the lever in a second direction opposite the first direction causes (i) the adaptor to move upward and (ii) the shaft to move from the lowered position to the raised position.
7. The food processing device of claim 2 , wherein the shaft is biased in the lowered position.
8. The food processing device of claim 2 , wherein the hub of the food processing tool is in a fixed vertical position relative to the base.
9. The food processing device of claim 8 , wherein:
the removable bowl has a central tube extending upwardly from the bottom surface, and
the hub of the food processing tool is coupled to an upper end of the central tube.
10. A food processing device comprising:
a base having a motor positioned therein,
a removable bowl coupled to the base,
a removable lid coupled to the bowl so as to define a processing chamber, the lid having a feed tube that opens into the bowl,
a food processing tool positioned in the processing chamber and driven by the motor to rotate about a central axis, the food processing tool including a hub defining the central axis and at least one adjustable blade extending outwardly from the hub, the adjustable blade being configured to rotate about a pivot axis extending through the hub orthogonal to the central axis, and
an adjustment assembly operable to cause the adjustable blade to rotate about the pivot axis while the food processing tool is driven by the motor.
11. The food processing device of claim 10 , wherein the adjustment assembly includes an adaptor having an upper end coupled to the food processing tool and a lower end coupled to the base.
12. The food processing device of claim 11 , wherein:
the removable bowl has a central tube extending upwardly from a bottom surface thereof,
the adaptor is positioned in the central tube of the bowl, and
the hub of the food processing tool is coupled to an upper end of the central tube.
13. The food processing device of claim 12 , wherein the adjustable blade is configured to rotate between:
a first position in which a cutting edge of the adjustable blade extends substantially horizontally, and
a second position in which the cutting edge extends substantially vertically.
14. A food processing tool for a domestic food processing device, comprising:
a hub including a socket sized to receive an output shaft of the food processing device, the hub defining a central rotation axis of the food processing tool,
a shaft movably coupled to the hub, the shaft being configured to move vertically along the central rotation axis, and
a pair of adjustable blades extending outwardly from the hub, each blade having a cutting edge formed thereon,
wherein each adjustable blade is pivotally coupled to the shaft such that vertical movement of the shaft causes the adjustable blades to pivot about an axis extending orthogonal to the central rotation axis.
15. The food processing tool of claim 14 , further comprising an adaptor having an upper end coupled to the shaft and a lower end having a plurality of teeth formed thereon.
16. The food processing tool of claim 14 , wherein each adjustable blade is configured to pivot between (i) a first position in which the cutting edge extends horizontally, and (ii) a second position in which the cutting edge extends vertically.
17. The food processing tool of claim 16 , wherein the adjustable blades are biased in the second position.
18. The food processing tool of claim 14 , wherein each adjustable blade includes:
a cylindrical base that defines the axis, and
a pin extending outwardly from the cylindrical base, the pin being offset from the axis and received in an opening defined in the shaft.
19. The food processing tool of claim 18 , further comprising a hollow tube secured to the hub, wherein the cylindrical bases of the adjustable blades are positioned at opposite ends of the hollow tube, and an upper end of the shaft extends through a slot defined in the hollow tube.
20. The food processing tool of claim 19 , further comprising a spring positioned between the upper end of the shaft and an inner wall of the hub.
