Abstract
An apparatus comprises a housing having a shape and size suitable for being held in a single hand of a user. A nail file head is coupled to the housing. An electric drive device is contained within the housing and configured to rotationally oscillate the nail file head about an axis. An abrasive surface is coupled to the nail file head configured to trim or smooth a fingernail or toenail when the nail file head is oscillated. The abrasive surface extends around and faces radially away from the axis.
Claims21
An apparatus comprising:
- a housing having a shape and size suitable for being held in a single hand of a user;
- a nail file head coupled to the housing;
- an electric drive device contained within the housing and configured to rotationally oscillate the nail file head about an axis;
- and
- an abrasive surface coupled to the nail file head and configured to trim or smooth a fingernail or toenail when the nail file head is oscillated, the abrasive surface extending around and facing radially away from the axis.
An apparatus comprising:
- a nail file head configured to rotationally oscillate about an axis;
- an abrasive surface coupled to the nail file head and configured to trim or smooth a fingernail or toenail when the nail file head is oscillated;
- and
- a stem extending from the nail file head and configured to releasably couple the nail file head to a housing, the stem including one or more radially extending features configured to mate with one or more corresponding radially extending features of the housing.
An apparatus comprising:
- a nail file head configured to rotationally oscillate about an axis;
- a first abrasive surface coupled to the nail file head and configured to trim or smooth a fingernail or toenail when the nail file head is oscillated;
- a second abrasive surface coupled to the nail file head and configured to trim or smooth fingernail or toenail when the nail file head is oscillated;
- and
- a stem extending from the nail file head and configured to releasably couple the nail file head to a housing, the stem including two or more axially extending grooves and a bulbous proximal tip, the two or more axially extending grooves configured to mate with one or more corresponding axially extending projections of the housing, the bulbous proximal tip configured to snap fit into the housing upon coupling the nail file head with the housing.
A method of filing or trimming a fingernail or toenail comprising:
- oscillating a nail file head about an axis, a distal end and a proximal end, the proximal end of the nail file head configured to be coupled to a housing, the nail file head having a first abrasive surface coupled to a distal end of the nail file head and perpendicular to the axis and a second abrasive surface coupled to the nail file head, the second abrasive surface extending around and facing radially away from the axis;
- and
- contacting one of the first or second abrasive surfaces with the fingernail or toenail to trim or file the fingernail or toenail.
