Abstract

Vibrating grooming device comprising a vibrating head (1) with bristles and/or tines (3) and a handle (2), the vibrating head comprising a motor (10) and an oscillating mass (11), the device characterized by the oscillating mass being disposed to oscillate linearly along an oscillating axis.

Claims

1. Vibrating grooming device comprising a vibrating head with bristles and/or tines and a handle, the vibrating head comprising a motor and an oscillating mass, the device characterized by the oscillating mass being disposed to oscillate linearly along an oscillating axis.

2. Device according to claim 1 wherein the oscillating axis is parallel to a bristle or tine extending direction.

3. Device according to claim 1 or 2 wherein the handle comprises a core and a sheath, the sheath being connected to the core by a vibration damping means.

4. Device according to claim 3 wherein the core comprises a housing for a power supply.

5. Device according to any preceding claim wherein the head comprises a carrier which is connected to the oscillating mass at one end and a crown gear mounted off-center pin at the other, the crown gear engaging a motor drive shaft.

6. Device according to claim 5 wherein the carrier comprises a shaft between its ends which passes through a fixed bushing.

7. Device according to any preceding claim comprising means for stabilizing the vibrating head with respect to the handle in order to prevent the grooming head from rotating about its longitudinal axis.

8. Device according to any preceding claim comprising means for stabilizing the grooming head with respect to the handle in order to prevent the grooming head from translating in any direction other than along the oscillating axis.

9. Device according to any preceding claim wherein the vibrating movement is from 20-200 Hz.

10. Device according to any preceding claim wherein the vibrating movement frequency is from 30 to 50 Hz.
