Abstract
A self-cleaning brush having a sliding cleaning element. The sliding cleaning element is received on the body of the brush such that when the brush becomes fouled with foreign material the cleaning element may slide along the length of the brush body and free any foreign material from the bristles of the brush.
Description




FIELD OF THE INVENTION




The present invention pertains to brushes, and more particularly to brushes that are self-cleaning. More particularly, the present invention relates to a self-cleaning styling brush, which contain bristles projecting circumferentially, which style of brush finds particular utility in hair-styling when used in combination with hair dryers and/or related types of styling techniques.




BACKGROUND




A brush, such as a hair brush, tends to pick up foreign material, such as hair, debris, etc., with use. The foreign material tends to foul the brush and to transfer the foreign material during subsequent uses. To prevent this problem the brush must be periodically cleaned such as by using another brush or a comb. This cleaning process is often time-consuming and inconvenient, and furthermore, it is seldom entirely effective.




In consideration of the problem of cleaning a brush, a number of disclosures have been put forward in an attempt to solve this problem. U.S. Pat. No. 6,021,542, to Norman, teaches a self cleaning hair brush that utilizes a plurality of perforated sheets disposed at the base of the bristles. As the bristles become fouled, the top most of the perforated sheets is removed from the brush, therein sweeping the bristles and pulling off any foreign material.




Along a similar line, U.S. Pat. No. 5,600,865, to Morrison, teaches a brush having a removable perforated plate disposed at the base of the bristles. Much the same as the Norman patent, when the brush becomes fouled the perforated plate is removed, therein carrying away any foreign material. Unlike Norman, however, the perforated plate of Morrison is then reattached to the brush by threading the bristles through the perforations and re-securing the perforated plate to the brush.




Along a different line is U.S. Pat. No. 4,225,997, to Thomas, et al. The brush of Thomas accomplishes the cleaning of the brush by retracting the bristles. By the teachings of Thomas, when the brush becomes fouled the bristles are retracted, therein releasing any foreign matter that has become ensnared in the bristles.




SUMMARY




A self cleaning brush comprising a body having a plurality of bristles extending from at least a portion of said body. A cleaning element is slidably disposed on said body, wherein the sliding element contains a plurality of projections which engage with said bristles. The cleaning element projections further define a space between the projections for the bristles to pass as the cleaning element slides along the brushy body. The space is of a size and geometry to engage said bristles and to clean said bristles as said cleaning element slides along said brush body.




In alternative embodiment, the present invention also relates to a self cleaning brush comprising a body having a plurality of bristles extending from at least a portion of said body including grooves positioned between said bristles and a cleaning element slidably disposed on said body, said sliding element containing a plurality of projections which slidably engage within said grooves. The cleaning element projections define a space between the projections for the bristles to pass as said cleaning element slides along said body, wherein said space is of a size and geometry to engage said bristles and to clean said bristles as said cleaning element slides along said brush body.

DESCRIPTION OF THE INVENTION




Referring to

FIGS. 1 and 2

, an exemplary self cleaning brush


10


consistent with the present invention is schematically illustrated. The brush


10


preferably comprises a brush body


14


and a handle


12


extending from the proximal end of the body


14


. The handle


12


and the body


14


may preferably be formed as a single unitary piece, or may alternately comprise a plurality of assembled pieces.




The body


14


of the brush


10


comprises a plurality of bristles


16


extending therefrom. Preferably the bristles


16


are arranged in a plurality of longitudinally oriented rows extending most of the length of the body


14


of the brush


10


. As illustrated in

FIGS. 1 through 3

, the longitudinally oriented rows of bristles


16


are preferably separated by longitudinal grooves


18


in the body


14


of the brush


10


.




The self-cleaning brush


10


consistent with the present invention further comprises a cleaning element


20


slidably retained on the body


14


of the brush


10


. In the exemplary brush


10


, the cleaning element


20


comprises an annular body having an inner diameter configured to receive the body


14


of the brush therethrough. Preferably the cleaning element


20


is secured against axial removal from the body


14


by an end cap


26


having a peripheral dimension greater than the inner diameter of the cleaning member.




The cleaning element


20


preferably comprises radially disposed finger projections


22


disposed on the forward face of the cleaning element


20


, i.e. the face opposite the handle


12


. Preferably fingers


22


are configured to be aligned with, and ride in the grooves


18


of the brush body


14


when the cleaning element


20


is received on the brush body


14


. It is further preferred that the fingers


22


are angled such that the longitudinal extension is greater at the inner diameter of the cleaning element


20


than at the outer diameter.




Furthermore, the finger projections define a space therebetween for the bristles to pass as the cleaning element slides along the brush body. Preferably, the space comprises a plurality of slot elements


24


disposed between each pair of adjacent fingers


22


. The slot elements


24


generally comprise an outwardly extending radial notch in the cleaning element


20


.




With reference to

FIG. 2

, the method of operation of the self cleaning brush


10


is illustrated. As the brush


10


is used, the bristles


16


will collect hair and other debris in the bristles


16


themselves, and spanning the space between the rows of bristles


16


. The brush


10


is cleaned by sliding the cleaning element


20


axially down the length of the body


14


of the brush


10


. As the cleaning element


20


travels down the length of the body


14


, the finger projections


22


will remove any hair or debris spanning adjacent rows of bristles


16


. The radially outwardly and rearwardly angle of the fingers


22


will force any hair or debris spanning the rows of bristles


16


to be forced away from the bristles and away from the body


14


of the brush. The hair and debris removed from the brush may be transferred to the outer circumference of the cleaning element


20


, from where it may be easily removed and discarded.




The cleaning action of the cleaning element


20


as it travels down the length of the body


14


of the brush


10


is further increased by the slot elements


24


disposed on the cleaning element. The notch of slot elements


24


preferably extends outwardly less than the height of the bristles


16


. Because of this configuration, as the cleaning element


20


travels down the body


14


, the bristles


16


will be caused to deflect toward the distal end of the body


14


, i.e., away from the cleaning element


20


. This deflection of the bristles


16


will aid in freeing any debris or hair ensnared in the bristles


16


and promote the transfer of any such debris away from the bristles


16


and the body


14


of the brush


10


.




While the invention has hereinabove been illustrated and described as having a round body


14


and annular cleaning member


20


, this should not be understood to be limiting. The use of alternate configurations are herein contemplated. Alternate configurations may comprise a generally planar body having bristles projecting from either one or both sides. When such a configuration is employed, the cleaning element may comprise a rectangular member having an opening therethrough configured in size and shape to be slidable on the body.




Therefore, while this invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for the use in numerous other embodiments. The invention is, therefore, not to be limited by the exemplary embodiments described in detail hereinabove, but only by the claims appended hereto.
