Fingernail brush having angularly adjustable bristles
First Claim
1. A fingernail brush, comprising:
- a housing sized and configured for gripping by a human hand, the housing comprising a bristle opening;
a bristle assembly that includes;
a bristle support pivotably secured within the housing so as to be pivotable about a pivot axis; and
a first plurality of bristles secured to the bristle support so as to extend through the housing; and
a bristle-angle-adjustment mechanism operatively configured to permit a user to adjust the plurality of bristles to a desired bristle sweep angle from among a plurality of bristle sweep angles and hold the first plurality of bristles at the desired bristle sweep angle;
further comprising a vibration generator operatively connected to the bristle assembly to as to impart sonic vibration into the first plurality of bristles when the vibration generator is operating.

Abstract
A fingernail brush that includes bristles that are angularly adjustable by a user of the brush. In one embodiment, the fingernail brush includes a housing and a bristle assembly having a bristle support and at least one row of bristles. The bristle assembly is rotatably coupled to the housing so that a user can rotate the bristles to a desired relative bristle angle. In some embodiments, the bristles are present in a bristle channel formed as a recess in a face of the housing. The angular adjustability of the bristles allows a user to set the bristles to a relative bristle angle appropriate for the way the user intends to orient their fingertips relative to the fingernail brush. In some embodiments, a fingernail brush of the present disclosure may include one or more vibration generators that cause bristles to vibrate at a sonic frequency, an ultrasonic frequency, or both, to enhance cleaning efficacy.
