Fingernail brush having angularly adjustable bristles
First Claim
1. A fingernail brush, comprising:
- a housing having a longitudinal axis and sized and configured for gripping by a human hand, the housing comprising an exterior, an interior cavity and a bristle opening extending from the interior cavity to the exterior and having a length parallel to the longitudinal axis;
a bristle assembly that includes;
a bristle support movably secured within the interior cavity of the housing; and
a first plurality of bristles secured to the bristle support so as to extend through the bristle opening of the housing from the interior cavity to the exterior and along the length of the bristle opening; and
a bristle-angle-adjustment mechanism operatively engaged with the bristle assembly so that a user can actuate the bristle support so as to permit the 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.

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.

23. A fingernail brush, comprising:
-
a housing sized and configured for gripping by a human hand, the housing comprising; an exterior; an interior cavity; first and second faces spaced from one another on the exterior of the housing; lateral sides located adjacent each of the first and second faces and providing gripping regions for a user to grip and hold the fingernail brush during use of the fingernail brush to clean one or more fingertips and/or one or more fingernails; and a bristle opening having a longitudinal axis and extending through the first face from the interior cavity to the exterior; a bristle assembly that includes; a bristle support pivotably secured within the interior cavity of the housing so as to be pivotable about a pivot axis parallel to the longitudinal axis, the bristle support being elongate along the pivot axis; and a first plurality of bristles secured to the bristle support so as to extend through the bristle opening of the housing from the interior cavity to the exterior, the first plurality of bristles arranged in a line parallel to the pivot axis of the bristle support and the longitudinal axis of the bristle opening; a bristle-angle-adjustment mechanism operatively configured to permit a user to pivot the bristle support about the pivot axis so as 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; and a second plurality of bristles fixedly secured to the housing and extending from the second face. - View Dependent Claims (24, 25, 26, 27)
