Abstract

A mincer includes a housing, a hinged door, a handle, a cam, an axle, and a plurality of circular blades mounted on the axle. Rotation of the handle or knob with respect to the housing causes rotation of the cam with respect to the housing, which in turn causes the axle and the blades mounted thereon to travel radially outward or inward with respect to the housing to extend or retract the blades out of or into the housing. The mincer can be operated to extend the blades for operation and to retract the blades for storage. The door can be closed for operation and opened for cleaning of the mincer.

First claim

What is claimed is:

1. A mincer, comprising:
a first disk shaped plate including a first linear slot that extends through a thickness of the first disk shaped plate and radially with respect to the first disk shaped plate;
a first cam plate including a first arcuate slot that extends along a first arcuate path through the first cam plate;
an axle that extends through the first linear slot and through the first arcuate slot such that rotation of the first cam plate with respect to the first disk shaped plate causes the axle to move through the first linear slot and linearly with respect to the first disk shaped plate; and
a circular blade mounted on the axle.

2. The mincer of claim 1 , wherein the first arcuate path of the first cam plate extends from a first location proximate a center of the first cam plate to a second location proximate an outer peripheral edge of the first cam plate.

3. The mincer of claim 1 , wherein the first arcuate slot extends along the first arcuate path forming a portion of a circle.

4. The mincer of claim 3 , wherein the circle has a center offset from a center of the second plate.

5. The mincer of claim 1 , wherein the first disk shaped plate is a cylindrical.

6. A mincer, comprising:
an outer shell having a substantially cylindrical shape with opposing sides spaced from and parallel to each other and a central axis, the outer shell having a rotatable handle positioned on one of said opposing sides, and at least one blade slot positioned in a curved portion of the outer shell;
a cam configured to fit between said opposing sides of said outer shell and having opposing sides adjacent the opposing sides of the outer shell; and
at least one circular blade rotatably mounted within the cam and aligned with the at least one blade slot, the at least one circular blade having an axis of rotation different than the central axis;
wherein rotation of the handle in one direction causes the at least one circular blade to be radially displaced relative to the central axis such that it extends outward through said at least one slot, and rotation of the handle in an opposite direction radially retracts the at least one circular blade into the at least one slot in the outer shell preventing exposure of the same when the mincer is not in use.

7. The mincer of claim 6 , wherein said outer shell further comprises a curved door assembly hingedly connected to the curved portion, the at least one blade slot being positioned in the door assembly.

8. The mincer of claim 6 , further comprising a mechanism integrated into the outer shell and the cam and configured to convert rotation motion of the rotatable handle into a linear radial displacement of the at least one circular blade with respect to the central axis of the outer shell.

9. The mincer of claim 8 , wherein the mechanism comprises:
one of the opposing sides of the outer shell comprising a first plate including a first linear slot that extends linearly through the first plate;
one side of the cam adjacent the first plate of the outer shell comprising a second plate including a first arcuate slot that extends along a first arcuate path through the second plate, said second plate being in mechanical communication with the rotatable handle; and
an axle positioned on the axis of rotation of the at least one blade and extending through the first linear slot and through the first arcuate slot such that rotation of the second plate with respect to the first plate causes the axle to move through the first linear slot and linearly with respect to the first plate.

10. The mincer of claim 9 , further comprising:
the other of the opposing sides of the outer shell comprising a third plate including a second linear slot that extends linearly through the third plate, the third plate rigidly coupled to and aligned with the first plate; and
the other of the sides of the cam comprising a fourth plate including a second arcuate slot that extends along a second arcuate path through the fourth plate, the fourth plate being rigidly coupled to and aligned with the second plate; wherein the axle extends through the second linear slot and through the second arcuate slot.

11. A mincer, comprising:
a first plate including a first linear slot that extends linearly through the first plate;
a first cam plate including a first arcuate slot that extends along a first arcuate path through the first cam plate;
a second plate including a second linear slot that extends linearly through the second plate, the second plate rigidly coupled to and aligned with the first plate; and
a second cam plate including a second arcuate slot that extends along a second arcuate path through the second cam plate, the second cam plate rigidly coupled to and aligned with the first cam plate;
an axle that extends through the first linear slot, the first arcuate slot, the second linear slot and the second arcuate slot such that rotation of the first cam plate with respect to the first plate causes the axle to move through the first and second linear slot and linearly with respect to the first plate and second cam plate, respectively; and
a circular blade mounted on the axle.
