  • Patent number: 10278486
    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.
