  • Publication number: 20060000423
    Abstract: A self-cleanable hairbrush for use on animals or humans is described that has a frame with strands stretched across it. In one embodiment, the frame is attached to the brush by a pivoting hinge and may be pivoted by the hinge to a position in which the frame is seated flat against a bristle-side of the brush, allowing the strands to slip between the bristles and the frame to be secured in place. As the brush is used, loose hairs, fur, or other debris may become entangled in the bristles. Releasing the frame and allowing it to swing up through the bristles gathers the entangled debris and removes it from bristles, allowing it to be disposed of. The frame and strands may then be re-seated against the bristle-side of the brush, leaving the brush cleaned and ready for re-use.
