Hand operable juicer

摘要

A hand operable juicer having a handle extending from beneath a juice receptacle is described. The handle has a drive link end that couples with a drive mechanism to rotate a drive shaft that extends up through a drive shaft conduit and couples with a pulping crown. Gear and crank type drive mechanisms are described. In some embodiments of the invention, the drive mechanism is configured to provide a rotational advantage, whereby a certain degree of rotation of the handle around the pulping crown rotational axis produces a higher degree of rotation of the pulping crown. The hand operable juicer described is easy to operate and easy to clean.

1. A hand operable juicer comprising:
a. a juice receptacle comprising:
i. a perimeter wall;ii. a receptacle base; andiii. a spout extending from the top portion of the perimeter wall; b. a drive shaft conduit that is an integral part of the juice receptacle and extends up from the receptacle base comprising:
i. a conduit perimeter wall configured around an opening in the receptacle base and extending up from the receptacle base;wherein, in use, a quantity of juice collects in the receptacle between the perimeter wall and the drive shaft conduit;
c. a pulping crown having a rotational axis; d. a handle having an extended end and a drive link end; e. a gear type drive mechanism configured under the receptacle base and configured to rotate the pulping crown when said handle is rotated comprising:
i. a drive gear coupled to the drive shaft; andii. a gear wedge coupled to the drive link end of the handle;  whereby the drive gear and gear wedge have a plurality of gear teeth and are configured to mate with each other such that when the handle is rotated with respect to a pin offset from and parallel with a rotation axis of a drive shaft, the plurality of gear teeth of the gear wedge engage the drive gear which rotates the pulping crown; f. said drive shaft having an axial length that extends from the gear type drive mechanism below the receptacle base, through the drive shaft conduit to the pulping crown, where it is coupled to the pulping crown; g. a filter that rests on the top portion of the receptacle perimeter wall and comprises:
i. a plurality of openings; h. a base extension that extends down from the receptacle base and comprises a handle opening that extends around a portion of a rotation axis of the pulping crown;  wherein the handle extends out from the base extension through the handle opening from the gear type drive mechanism to the exterior of the perimeter wall,  wherein the drive shaft couples the gear type drive mechanism with the pulping crown;  wherein the juicer is hand operable whereby when the handle is rotated about the rotational axis of the pulping crown, the pulping crown rotates in a gear ratio of the gear wedge to drive gear and wherein said gear ratio is at least 1.5;  wherein, in use, juice is collected in the juice receptacle between the perimeter wall and the drive shaft conduit such that said collected juice is isolated from the gear type drive mechanism configured under the juice receptacle; and  wherein said hand operable juice is configured to dispensed said collected juice out of the juice receptacle through the spout.
