Abstract

A motorized citrus press has a reamer and a pivoting arm that carries a fruit dome. The reamer has primary ribs that protrude from a rib supporting surface. Each primary rib has an upper profile and a lower profile that comprise a compound profile.

First claim

The invention claimed is:

1. A citrus press device with a motor for rotating a citrus reamer comprising:
a housing containing a motor for driving the reamer;
an arm being hinged to the housing at one end and having a handle at a free end;
the arm supporting for movement toward the reamer, a fruit dome that cooperates with the reamer;
the reamer having primary ribs, each rib having an apex, the apex comprising an elevated projection;
the elevated projections spaced from and surrounding a central pin that acts as a spacer between the reamer and the dome;
the reamer having a compound profile comprising an upper profile and a lower profile, the lower profile having a longitudinal radius, there being a visible transition between the upper profile and the lower profile.

2. The device of claim 1 , wherein:
the dome is removable and further comprises a stub having a slot that receives an o-ring and wherein the arm further comprises an opening for receiving the stub;
the dome having an alignment rib and the arm having a slot for receiving the alignment rib.

3. The device of claim 2 , wherein:
the dome has internal ribs with profiles that closely resemble the profile of the primary ribs.

4. The device of claim 2 , wherein:
the opening is a through opening.

5. The device of claim 1 , wherein:
the upper profile defines an acute apex angle with reference to a location above the central pin.

6. The device of claim 5 , wherein:
the upper profile is approximately flat.

7. The device of claim 1 , wherein:
the elevated projections each comprise a spike.

8. The device of claim 1 , wherein:
the central pin is higher than the elevated projections.

9. The device of claim 1 , further comprising:
secondary ribs located between the primary ribs, the secondary ribs subdividing an exterior surface of the reamer into concave areas.

10. The device of claim 1 , wherein:
there are formed two inflection points, each being where the profiles transition between convex and concave along a length of a rib.

11. The device of claim 1 , wherein:
the dome has an inner shell and an outer shell, the inner shell having internal ribs formed on it.

12. The device of claim 1 , wherein:
the arm is hinged with a quadrilateral hinge.

13. The device of claim 1 , wherein:
the device has a strainer below the reamer; and
the reamer has paddles that extend away from a lower rim to sweep the strainer.

14. The device of claim 1 , wherein:
the primary ribs are tapered from a root to a radiused tip.

15. The device of claim 1 , wherein:
the device has a motor with an output shaft for rotating the reamer and the output shaft is mounted at an angle from vertical.

16. The device of claim 1 , wherein:
the device comprises a switch that is depressed when a main shaft of the motor is depressed and a second switch, being a lock-out switch associated with a position of the arm;
both switches requiring activation in order to activate the motor.

17. The device of claim 1 , wherein:
the primary ribs are four in number.
