Styling brush with retractable bristles
A retractable bristle brush has a handle with a stem attached at one end thereof to one end of the handle and extending longitudinally therefrom. A cylindrical barrel extends concentrically around the stem and has a plurality of spaced holes therethrough. A plurality of bristles is affixed at one end to the stem and project at their other end through the holes in the barrel. An actuator is connected with one of the barrel and stem to move the barrel and stem relative to one another to deflect the bristles and cause them to retract through the holes to a shielded position inside the barrel. The natural resiliency and memory of the bristles causes them to move the barrel and stem relative to one another to their original position with the bristles extended through the holes when pressure is released from the actuator.

FIELD OF THE INVENTIONThis invention relates to hair brushes, and more particularly to a styling brush for curling hair, wherein the brush has retractable bristles to enable it to be easily withdrawn from hair curled around the brush.
BACKGROUND ARTBrushes used for styling hair include brushes having a round cross-section, with bristles projecting radially outwardly from the brush around its circumference. These brushes are commonly used to curl hair by winding or wrapping the hair around the brush, and in most cases applying heat and/or one or more hair treatment solutions to set the curl. While such brushes are effective for the intended purpose, the disadvantage is that they are difficult to remove from the curl without disturbing it. The only way to remove the brush is to pull it axially out of the curl, either with or without first unrolling or partially unrolling the curl. In either event, strands of hair are enmeshed in the bristles of the brush and the curl or other style imparted to the hair is damaged.
In an effort to solve this problem, brushes have been designed that have retractable bristles so that after the curl is formed the bristles can be retracted and the brush pulled axially out of the curl without disturbing the styled hair. Exemplary of such prior art brushes are those described in U.S. Pat. Nos. 3,962,742, 4,191,200, 4,467,821 and 4,596,261. While these brushes do solve the problem of withdrawing the styling brush after the curl or other style is formed, they are relatively complex and expensive in construction, and/or are relatively difficult to operate.
Accordingly, there is need for a simple and inexpensive styling brush that is easy to use and that can be withdrawn from a curl or other hair style without disturbing the styled hair.
SUMMARY OF THE INVENTIONThe present invention is a simple and inexpensive styling brush that is easy to use and that can be withdrawn from a curl or other hair style without disturbing the styled hair.
With the present invention a stylist rolls the hair around the brush to form a curl, and when it is desired to remove the brush from the styled hair the stylist can use a single finger or the thumb on the hand holding the brush to retract the bristles so that the brush can be pulled from the styled hair without disturbing it.
More specifically, the brush of the invention comprises a handle with a longitudinally extending stem attached to one end of it, a barrel or mandril concentrically surrounding the stem and having a plurality of spaced holes through it, and a plurality of bristles attached to the stem and extending through the holes in the barrel. The barrel and stem are movable relative to one another to cause the bristles to either extend out through the holes or to retract into the barrel. Either the stem or the barrel can be moved to retract the bristles.
In its normal at-rest condition the bristles are extended so that the brush can be used normally to curl or otherwise style hair without requiring the user to first manipulate the bristles to place them in an operative position. In the preferred embodiments action by the user is required only to retract the bristles. A unique feature of the present invention is that the bristles themselves are used to cause relative movement between the stem and barrel, without requiring any user intervention to restore the brush to its normal usable condition, and eliminating parts that are used for that purpose in conventional retractable bristle brushes. However, spring means may be associated with the barrel or the stem, if desired, to aid in returning the barrel or stem to their original position, with the bristles extended.
In one form of the invention the barrel is movable relative to the stem, and in a second form the stem is movable relative to the barrel. In the first form the user has only to press his or her thumb against the rearward end of the barrel to cause it to move relative to the stem, deflecting the bristles, which are fixed at their inner end to the stem, and causing them to retract through the holes in the barrel so that they no longer contact the hair wound around the barrel. In the second form, a finger- or thumb-actuated button is connected through an opening in the handle with an extension on the rearward end of the stem to move the stem relative to the barrel, which is fixed to the handle, causing the bristles to deflect and retract through the openings in the barrel.
The barrel is longitudinally movable in a first embodiment of the first form of the invention, and rotatable in a second embodiment. Similarly, the stem is longitudinally movable relative to the barrel in a first embodiment of the second form of the invention, and rotatable relative to the barrel in a second embodiment. Rotation of the barrel or stem, whichever is movable, may be either right or left.
The holes through the barrel may be arranged in any suitable pattern, including circumferential rows, or longitudinal rows, or spiral rows, and may have any suitable shape, including round, oval, or other shape such as a slot that accommodates the bristles as they extend and retract and that supports them in their operative position. Guides may be provided on the interior of the stem to guide the bristles into the holes when they are moved from their retracted position to their extended position, either by way of deformations in the barrel itself or by attachment of separate guide members to the inner surface of the barrel. One form of guide may comprise a tube or straw-like bristle holder associated with each hole, and in which the bristles for that hole are confined and guided. The spaces of the barrel between the holes define blank areas where the bristles rest and are hidden when in their retracted position.
The barrel may be formed with longitudinal ribs that project above its outer surface to hold the hair wound around the barrel away from the exposed ends of any bristles protruding through the holes in the barrel.
The bristles may be withdrawn completely through the holes in their retracted position, or only partially withdrawn through the holes so that any potential problem of realignment of the bristles with the holes as they are moved from their retracted to their extended position is eliminated.
The stem may be of the twisted wire type or the plug type, and the bristles may be made of a plastic material, or comprise boar's hair, or be made of other suitable bristle material. In all forms of the invention the natural resiliency and memory of the bristles is used to move the barrel and stem relative to one another to extend the bristles.
Further, latch or detent means may be associated with the movable barrel or stem to hold it in its moved position, and the tab, button or barrel hub may be configured so that the finger can engage it to move the stem or barrel in both directions rather than in a single direction as described hereinafter in connection with the preferred embodiments.
A predetermined amount of tourmaline or silver may be added to the outer surface of the barrel to create an ionic atmosphere for added health benefits to the scalp and hair.
The foregoing, as well as other objects and advantages of the invention, will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, wherein like reference characters designate like parts throughout the several views, and wherein:
A first form of retractable bristle brush according to the invention is indicated generally at 10 in

The holes may have a circular shape as shown in the figures, or an oval shape (not shown), or slot (not shown), or other shape suitable to accommodate the bristles and support them in their extended position. Further, guide means (not shown) may be provided on the inner surface of the barrel to guide the bristles into the holes. The guide means may comprise tapered trough-like depressions leading to the holes on the inner surface of the barrel, or tube-like members affixed to the inner surface of the barrel and in which the bristle or cluster of bristles for that hole are confined and guided, or other means.
Although particular embodiments of the invention are illustrated and described in detail herein, it is to be understood that various changes and modifications may be made to the invention without departing from the spirit and intent of the invention as defined by the scope of the appended claims.
