Abstract

A hair brush adapted to prevent charging of the bristles and hair, according to the invention, has a multiplicity of small holes (7) formed in a brush base (2) at each of widthwise opposite end portions thereof and arranged at a spacing in a row longitudinally of the base, and an antistatic member (9) is so provided as to project from the multiplicity of small holes (7) slightly beyond the base surface (2a), whereby the antistatic member (9) is made stiff and prevented from bending down, rendering the brush easy to draw through hair for smooth brushing.

Claims

1. A hair brush comprising an electrically conductive brush base, a handle, a multiplicity of electrically conductive bristles provided upright on the surface of the brush base, and an antistatic member made of electrically conductive fiber and provided at each of widthwise opposite end portions of the brush base surface running longitudinally of the brush base;

wherein the handle has a mount toward one end in the longitudinal direction thereof, and the conductive brush base is fitted to the mount;

a multiplicity of small holes are formed in the brush base at each widthwise end portion thereof and arranged at a spacing in a row longitudinally of the base, the antistatic member being so provided as to project from the multiplicity of small holes slightly beyond the surface; and

wherein the small holes communicate at the rear side thereof with an elongated groove formed in the rear surface of the brush base, and the antistatic member is fitted at its base portion in the groove, a barlike fixing member being inserted between the inner wall defining the groove and the base portion of the antistatic member to fix the antistatic member.

2. A hair brush as defined in claim 1, wherein the brush base is made of a material prepared by admixing carbon with polyester elastomer or like synthetic resin, and the handle is molded of ABS or like synthetic resin, the antistatic member being made of an electrically conductive metal fiber, fiber having copper or like metal deposited on the surface thereof by vacuum evaporation, or acrylic fiber having adsorbed monovalent copper ion and having metallic copper separated out therein by reduction.

3. A hair brush as defined in claim 1, wherein the bristles are formed integrally with the brush base.

4. A hair brush as defined in claim 1, wherein a barlike grounding piece extends from longitudinal one end of the brush base, and the handle is formed with a dovetail groove corresponding to the grounding piece, the grounding piece being fitted in the dovetail groove so as to be exposed at the surface of the handle.

5. A hair brush as defined in claim 4, wherein the multiplicity of small holes and the bristles in a row at each widthwise end of the conductive brush base are arranged alternatively in a row.

6. A hair brush as defined in claim 1 wherein the top end of the antistatic member is projected through the small holes to a level 1 to 2 mm above the surface of the brush base.

7. A hair brush as defined in claim 6, wherein the mount is provided with engaging walls at its opposite ends in the longitudinal direction thereof, and the conductive brush base is fitted in the space between the engaging walls.

8. A hair brush as defined in claim 7, wherein a fitting ridge is provided at each of the widthwise outer ends of the conductive brush base, and the mount (3) is formed in its surface with a groove corresponding to the ridge, the ridge being fitted in the groove.

9. A hair brush according to claim 1, wherein the electrically conductive brush base has a projecting side wall portion at each said widthwise end portion thereof, each said side wall portion having an exposed outer surface that lies flush with an outer surface of the mount at widthwise opposite sides of the brush.

10. A hair brush according to claim 7, wherein the electrically conductive brush base has a projecting side wall portion at each said widthwise end portion thereof, each said side wall portion extending between the engaging walls so as to have an exposed outer surface that lies flush with an outer surface of the mount at widthwise opposite sides of the brush.
