a frame;
a first lever including a grip portion, a contact portion and a first pivot location, the first pivot location being pivotally coupled to the frame, the first lever being pivotable about the first pivot location between an open position and a closed position;
a second lever having a second pivot location and a scoop portion, the second pivot location being pivotally coupled to the frame, the second lever being configured to rotate about the lever pivot location in response to actuation of the first arm lever, the second lever also having an elongated surface in slidable contact with the contact portion of the first lever, the elongated surface being oriented such that as the first arm moves from the open position toward the closed position, a distance increases between the contact portion of the first lever and the second pivot location;
a scoop coupled to the scoop portion of the second lever such that actuation of the second lever creates movement of the scoop from a retracted position corresponding to the open position of the first lever to an extended position corresponding to the closed position of the first lever.
11. The segmenter of claim 10 wherein the scoop is extendable toward a triangular blade to form a segment-shaped compartment to entrap a fruit segment.
12. The segmenter of claim 11 wherein the triangular blade is stainless steel.
13. The segmenter of claim 10 wherein the distance between the second pivot location and the contact portion of the first arm lever continually increases, thus creating a continuously increasing mechanical advantage, when the first lever is moved toward the closed position from the open position.
14. The segmenter of claim 10 wherein the actuation of the first lever into the closed position causes the first lever to rotate in a clockwise direction while forcing the second lever to rotate in a counterclockwise direction.
15. The segmenter of claim 10 wherein the second lever includes a stop to limit the travel of the second lever.
16. The segmenter of claim 10, further comprising a spring attached to the second lever such that the spring acts to urge the first lever toward the open position.
17. The segmenter of claim 10 wherein the grip portion of the first lever is contoured to complement at least two fingers.
18. The segmenter of claim 10 wherein the elongated surface of the second lever is generally aligned along a major axis of the first lever when the first lever is in the open position.
19. The segmenter of claim 10 wherein the contact portion of first lever and the lengthwise portion of the second lever are contoured.
20. The segmenter of claim 10 wherein the contact portion of the first lever and the elongated surface of the second lever are configured with low-friction and wear resistant surfaces.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
