Abstract

An improved trimmer is structured to be held in the palm of a user's hand. The trimmer has a grinding drum that is advantageously structured to be situated in a palmar region of the user's hand that can be said to extend from the palm and to be generally bounded by the fingertips. When the trimmer is held in the palmar region, the thumb and certain fingers can support the trimmer, and other fingers that are not necessarily employed in supporting the trimmer are usable to operate a control switch of the trimmer. The control switch controls operation of a drive motor that is connected with a grinding drum which provides abrasive surfaces that are engageable with the animal nail or claw.

First claim

What is claimed is:

1. A trimmer that is structured to be usable to trim a claw of an animal, the trimmer comprising:
a housing that is structured to be held in the hand of a user, the housing including a user contact surface defining an arcuate surface for being held in the palm of the user;
a switch that operates the trimmer arranged at the user contact surface for user operating the switch when the trimmer is held in the palm;
a grinding apparatus comprising a cutter that is movable to trim the claw, the grinding apparatus being structured to be situated within a palmar region of the hand that extends from the palm and that is generally bounded by the fingertips when the housing is held in the hand of the user; and
a grinding shield that forms a wall around the cutter, the grinding shield extending from another surface of the housing that is an opposing surface of the user contact surface, the grinding shield including a first opening that faces in a direction away from the user contact surface and a second opening that faces in another direction that is perpendicular to the direction that the first opening faces, the first and second openings being configured to receive a pet claw for cutting by the cutter.

2. The trimmer of claim 1 wherein
the cutter comprising an abrasive element, and the trimmer further comprises a control apparatus having a motor that is structured to rotate the abrasive element and the switch is structured to control operation of the motor.

3. The trimmer of claim 2 wherein
the motor is structured to rotate the abrasive element in two opposite directions responsive to operation of the switch.

4. The trimmer of claim 3 wherein
the switch is movable in a first direction and in a second direction, the abrasive element being structured to rotate in a first direction responsive to movement of the switch in the first direction, the abrasive element being structured to rotate in a second direction responsive to movement of the switch in the second direction.

5. The trimmer of claim 4 wherein
the grinding apparatus is structured to rotate the abrasive element in the first direction at a velocity when the switch is pivoted a distance in the first direction, and wherein the grinding apparatus is structured to rotate the abrasive element in the first direction at a relatively greater velocity when the switch is pivoted a relatively greater distance in the first direction.

6. The trimmer of claim 3 wherein
the control apparatus further comprising an illumination apparatus having at least a first illumination element that is structured to become illuminated when the cutter is rotated.

7. The trimmer of claim 6 wherein
the at least first illumination element comprises a first directional light and a second directional light, the first directional light being structured to be illuminated when the abrasive element is rotated in the first direction and being further structured to provide a visual indication representative of the first direction, the second directional light being structured to be illuminated when the abrasive element is rotated in the second direction and being further structured to provide a visual indication representative of the second direction.

8. The trimmer of claim 7 wherein
the first and second directional lights are situated at alternate sides of the switch.

9. The trimmer of claim 6 wherein
the at least first illumination element comprises a lamp which, when illuminated, is structured to provide illumination in the vicinity of the cutter.

10. The trimmer of claim 6 wherein
the illumination of the at least first illumination element is structured to be visibly altered responsive to a continued rotation of the cutter for a predetermined period of time.

11. The trimmer of claim 2 wherein
the abrasive element comprises a substantially planar abrasive portion and an arcuate abrasive portion.

12. The trimmer of claim 1 wherein
the user contact surface defines a domed first portion of the housing, at least a portion of the first portion is structured to be situated adjacent the palm, the housing further comprising a second portion from which the cutter protrudes and which is otherwise generally planar.

13. The trimmer of claim 12 wherein
the control apparatus comprises a motor that is structured to rotate the abrasive element and the switch is structured to control operation of the motor, the switch being situated on the first portion.

14. The trimmer of claim 12 wherein
the housing further comprises a third portion situated on the second portion and structured to at least partially cover the cutter.

15. The trimmer of claim 12 wherein
the cutter comprises a substantially planar cutting surface and an arcuate cutting surface;
the third portion includes an arcuate opening formed therein that provides access to the substantially planar cutting surface; and
the third portion further includes another opening formed therein that provides access to the arcuate cutting surface.

16. The trimmer of claim 1 wherein the trimmer includes another housing that extends from the another surface, the cutter being housed in the another housing and the motor being housed in the housing.

17. The trimmer of claim 16 wherein
the grinding apparatus further includes a shaft extending between the housing and the another housing to operatively connect the motor and the cutter.
