Abstract

A pet nail grinder is provided, including, a grinder housing having a first, working end, and a second, opposite end; a drive system located within the grinder housing; a grinding bit connected to the drive system and projecting from the first end; and a control button connected to the drive system and projecting from the second end so that the drive system is operable by facing the second end towards a surface and impacting the control button against the surface.

First claim

What is claimed is:

1. A pet nail grinder, comprising:
a grinder housing having a first, working end, and a second, opposite end;
a drive system located within said grinder housing;
a grinding bit connected to said drive system and projecting from said first end;
a control button connected to said drive system and projecting from said second end so that said drive system is operable by facing said second end towards a surface and impacting said control button against said surface;
a separate spindle cap on said grinder housing, located closer to said working end than to said second end, said spindle cap being made of light transmissive material, and defining mounting points for at least one light, said at least one light constructed and arranged for illuminating said grinding bit;
said housing includes at least one intake vent adjacent said second end, and a second plurality of vents associated with said spindle cap and adjacent said at least one light;
said drive system includes a motor enclosed within said grinder housing, and said grinder further includes a heat sink disposed in said housing for securing said motor, said heat sink defining a tube with an opening dimensioned for accommodating said motor, and a plurality of support ribs radially extending from said tube, said support ribs being dimensioned for contacting inner surfaces of said grinder housing for securing said motor within said housing; and
said heat sink includes a supplemental ring having a larger diameter than said tube and connected to said support ribs for creating a plurality of honey-comb-like air channels.

2. The pet nail grinder of claim 1 , wherein said control button linearly reciprocates relative to said second end.

3. The pet nail grinder of claim 1 , wherein said drive system defines a longitudinal axis of said grinder, and said control button is centered along said longitudinal axis.

4. The pet nail grinder of claim 1 , further including four of said at least one lights being peripherally spaced around said spindle cap, each said light being secured in a bracket integrally formed with said spindle cap.

5. The pet nail grinder of claim 1 , wherein said drive system includes a motor with a drive spindle accommodating said grinding bit, said grinder including a cooling fan mounted to said drive spindle between said motor and said grinding bit.

6. The pet nail grinder of claim 5 , wherein said at least one intake vent includes a first plurality of vents closer to said second end than to said working end, and.

7. The pet nail grinder of claim 5 , further including said spindle cap having said at least one exhaust vent in fluid communication with said cooling fan and said at least one intake vent.

8. The pet nail grinder of claim 1 , wherein said heat sink is constructed of resilient material for absorbing vibrations generated by said motor, and said plurality of support ribs are disposed in a spaced relationship to each other to define air flow channels therebetween.

9. The pet nail grinder of claim 1 , wherein said motor has a drive spindle accommodating said grinding bit, said grinder including a spindle lock with a biased locking pin reciprocating transversely to an axis defined by said spindle, said locking pin having an actuator button with an upper surface positioned to extend no farther than an exterior surface of said grinder housing.

10. The pet nail grinder of claim 9 , wherein said spindle further includes a toothed spindle lug rotating with said spindle, and said spindle lock locking pin being in selective engagement with said spindle lug for periodically locking said spindle from rotation upon depression of said actuator button.

11. The pet nail grinder of claim 1 , wherein said grinder housing is constructed and arranged to inhibit rolling of the grinder on a substrate, including at least one of a non-circular transverse cross-section and a plurality of peripherally spaced, radially extending projections secured near said second end.

12. A pet nail grinder, comprising:
a grinder housing having a first, working end, and a second, opposite end;
a drive system located within said grinder housing;
a grinding bit connected to said drive system and projecting from said first end; and
a separate spindle cap on said grinder housing, located closer to said working end than to said second end, said spindle cap being made of light transmissive material, and defining mounting points for at least one light, said at least one light constructed and arranged for illuminating said grinding bit;
said drive system includes a motor enclosed within said grinder housing, and said grinder further includes a heat sink disposed in said housing for securing said motor, said heat sink defining a tube with an opening dimensioned for accommodating said motor, and a plurality of support ribs radially extending from said tube, said support ribs being dimensioned for contacting inner surfaces of said grinder housing for securing said motor within said housing; and
said heat sink includes a supplemental ring having a larger diameter than said tube and connected to said support ribs for creating a plurality of honey-comb-like air channels.

13. The pet nail grinder of claim 12 , further including four of said at least one lights being peripherally spaced around said spindle cap, each said light being secured in a bracket integrally formed with said spindle cap.

14. A pet nail grinder, comprising:
a grinder housing having a first, working end, and a second, opposite end;
a drive system located within said grinder housing;
a grinding bit connected to said drive system and projecting from said first end; and
said drive system includes a motor with a drive spindle accommodating said grinding bit, said grinder including a cooling fan mounted to said drive spindle between said motor and said grinding bit;
said housing includes at least one intake vent at said second end, and a separate spindle cap on said grinder housing, said spindle cap located closer to said working end than to said second end, said spindle cap having at least one exhaust vent in fluid communication with said cooling fan and said at least one intake vent;
said drive system includes said motor enclosed within said grinder housing, and said grinder further includes a heat sink disposed in said housing for securing said motor, said heat sink defining a tube with an opening dimensioned for accommodating said motor, and a plurality of support ribs radially extending from said tube, said support ribs being dimensioned for contacting inner surfaces of said grinder housing for securing said motor within said housing; and
said heat sink includes a supplemental ring having a larger diameter than said tube and connected to said support ribs for creating a plurality of honey-comb-like air channels.

15. The pet nail grinder of claim 14 , wherein said at least one intake vent includes a first plurality of vents closer to said second end than to said working end, and a second plurality of vents adjacent a peripheral edge of said spindle cap in proximity to said working end.

16. The pet nail grinder of claim 14 , wherein said heat sink is constructed of resilient material for absorbing vibrations generated by said motor, and said plurality of support ribs are disposed in a spaced relationship to each other to define air flow channels therebetween.
