Abstract

A battery powered, automatic feed, disc type grater with a storage cover, interchangeable discs and waterproof motor gives users the ability for one touch operation and extended refrigerator storage and tap water cleaning of the components of the grater. A storage cap/container provides extended storage capability, while a ring stand enables the grater to be operated with the touch of a button while the grater is suspended over an area into which grated material may fall. A pusher assembly provides constant and automatic pressure on a material to be grated and against a grater disk, and a divider sleeve derives turning resistance for material to be grated from the pusher assembly while protecting the holder from contact with the material to be grated.

Claims

1. A grater comprising:

a main housing;

a motor supported within the main housing;

a switch supported by the main housing and actuatable from outside the main housing;

at least one battery supported within the main housing and controllably electrically connected through the switch and to the motor;

a gear set mechanically driven by the motor and having an output drive shaft;

a pusher assembly for providing force and displacement with respect to the main housing;

a grater disk having a first side and a second side and having a shaft engagement fitting extending away from the first side of the grater disk for fitting onto the output drive shaft; and

a holder having a lower end for providing support to the second side of the grater disk, and an upper end for removable attachment to the main housing, and for containing a material to be grated to be pushed by the pusher assembly and against the grater disk while the grater disk is turning to produce a grated product.

2. The grater as recited in claim 1 and further comprising a storage cap/container which fits closely around the holder to isolate and contain the material to be grated to facilitate the use of the grater for extended storage of the material to be grated within the holder.

3. The grater as recited in claim 1 and further comprising a divider, within the holder, to act to prevent material to be grated from turning as the grater disk turns.

4. The grater as recited in claim 3 wherein the divider imparts turning resistance by mechanical contact with the pusher assembly.

5. The grater as recited in claim 1 wherein the holder is round and further comprising a ring stand having a ring into which the holder fits, and having a plurality of legs attached to the ring whereby the grater may be positioned above areas to which grated material may fall.

6. The grater as recited in claim 1 wherein the switch supported by the main housing and actuatable from outside the main housing holder is actuatable through an elastomeric membrane.

7. The grater as recited in claim 1 wherein the pusher assembly further comprises:

a spring guide and containment tube have a first end fittable into a bore within the main housing, and a second end;

a pusher plate attached to the second end of the spring guide and containment tube; and

a spring set within the spring guide and containment tube arranged to urge the pusher plate away from the main housing.

8. The grater as recited in claim 7 wherein the spring set further comprises:

A spiral spring;

a first spring guide having a first round end and a first pair of interfit structures extending away from the round end and terminating in a joining web; and

a second spring guide having a first round end and a second pair of interfit structures extending away from the round end and terminating in web engaging structures and interfitting with the first spring guide with both first and second spring guide first and second pair of interfit structures extending adjacent each other within the spiral spring, the first and second spring guides acting to permit compression of the spiral spring, but limit the expansion of the spiral spring.
