Abstract

In a hair brush including a handle having a longitudinal tip end portion, a teeth holding base portion is provided in the longitudinal tip end portion of the handle. A plurality of comb-shaped blades is overlapped to make sliding contact with each other, the comb-shaped blades having edges and being provided in the longitudinal tip end portion of the handle. A thinning member is provided to cover the edges of the comb-shaped blades, the thinning member having a plurality of first apertures. A driving unit for reciprocates at least one of the comb-shaped blades so as to clip hair strands introduced between the edges of the comb-shaped blades through the first apertures of the thinning member. An opening-and-closing member is provided to open and close the first apertures of the thinning member.

Claims

1. A hair brush comprising:

a handle having a longitudinal tip end portion;

a teeth holding base portion provided in the longitudinal tip end portion of the handle;

a plurality of comb-shaped blades overlapped to make sliding contact with each other, the comb-shaped blades having edges and being provided in the longitudinal tip end portion of the handle;

a thinning member provided to cover the edges of the comb-shaped blades, the thinning member having a plurality of first apertures;

a driving unit for reciprocating at least one of the comb-shaped blades so as to clip hair strands introduced between the edges of the comb-shaped blades through the first apertures of the thinning member; and

an opening-and-closing member for opening and closing the first apertures of the thinning member.

2. The hair brush of claim 1, further comprising a slide support mechanism for supporting the opening-and-closing member so as to slide along the thinning member.

3. The hair brush of claim 2, wherein the opening-and-closing member has a plurality of second apertures, the second apertures being arranged to ensure that, when the opening-and-closing member is slid into a specified position, some of the first apertures overlap with the second apertures so as to come into an open state and the remaining first apertures are closed by the opening-and-closing member.

4. The hair brush of claim 1, further comprising an opening degree adjusting mechanism for variably setting the opening degree of the first apertures.

5. The hair brush of claim 1, further comprising a switch with an operation knob for switching the operation of the driving unit and an interlocking mechanism for operatively interconnecting the operation knob of the operation switch and the opening-and-closing member wherein the opening-and-closing member is configured to move at least between an open position in which to open the first apertures and a closed position in which to close the first apertures.

6. The hair brush of claim 2, further comprising a switch with an operation knob for switching the operation of the driving unit and an interlocking mechanism for operatively interconnecting the operation knob of the operation switch and the opening-and-closing member wherein the opening-and-closing member is configured to move at least between an open position in which to open the first apertures and a closed position in which to close the first apertures.

7. The hair brush of claim 3, further comprising a switch with an operation knob for switching the operation of the driving unit and an interlocking mechanism for operatively interconnecting the operation knob of the operation switch and the opening-and-closing member wherein the opening-and-closing member is configured to move at least between an open position in which to open the first apertures and a closed position in which to close the first apertures.

8. The hair brush of claim 4, further comprising a switch with an operation knob for switching the operation of the driving unit and an interlocking mechanism for operatively interconnecting the operation knob of the operation switch and the opening-and-closing member wherein the opening-and-closing member is configured to move at least between an open position in which to open the first apertures and a closed position in which to close the first apertures.
