the present invention relates to an improved hairbrush having a particularized configuration whereby the configuration results in an increased efficiency in the brushing action . in one embodiment , the brush of the present invention can generally be described as egg shaped . brush 10 is assembled of component parts including cap 12 constructed and arranged to be mounted on barrel 15 . barrel 15 is configured to mount onto rail 17 . rail 17 includes a rail shaft 18 that is constructed and arranged to receive about its thumb rest 20 . thumb rest 20 ultimately could next to handle 21 . bristles 14 are configured to nest with in the inner cavity of barrel 15 . bristles 14 extend outward through barrel 15 through a plurality of barrel screen 16 incorporated about the circumferential surface of barrel 15 . in one embodiment , end cap 11 has incorporated there on a plurality of cap teeth 12 . cap 11 is configured with a male mt . 13 constructed and arranged to interact with a female mount on barrel 15 . the male - female connection of 11 to barrel 15 is any one of screw fit , snap fit , and the like . barrel 15 is configured two connect on to rail 17 at rail cap 19 . handle 21 has a mounting and 23 constructed and arranged for attachment with thumb rest 20 . handle 21 is configured with a hollow interior providing a receiving cavity for rail shaft 18 therein . handle 21 has disposed about its circumference on the outer surface grip 22 . handle 21 is further configured with a handle terminal and 24 in one embodiment , the barrel screen 16 is configured to form a cylindrical shape with tapered end portions . the amount of taper , in one embodiment , is the same on each end . in another embodiment , the amount of taper differs on either end . as generally understood the shape of an egg is approximately half of each prolate ( long ) and is a roughly spherical ( potentially even slightly oblate / short ) ellipsoid joined at the equator , sharing a principal axis of rotational symmetry , as illustrated above . although the term egg - shaped usually implies a lack of reflection symmetry across the equatorial plane , it may also refer to true prolate ellipsoids . it can also be used to describe the 2 - dimensional figure that , revolved around its major axis , produces the 3 - dimensional surface . the egg shape configuration of barrel 15 provides a user increased efficiency in providing bristles 14 to contact hair roots of those hairs substantially towards the center of the scalp . the configuration further provides variations in diameter whereby sides are smaller than the middle and when the bristles of the brush contact the hair the hair will be subjected to increased force which will result in a tighter curl on the outside edges compared the to the middle portion of the head . it has been discovered that brushes of this configuration will result in an ability to curl hair such that the curl has an increased duration , i . e ., the curl will last longer than brushes conventionally used . when the brush 10 of the present invention is used in conjunction with a blow dryer as is commonly known in the art there is a tight curl on the outside and a large curl on the inside of the same section . brush bristles 14 extend generally outward from the center of the brush . the bristles 14 protrude through a curved surface of barrel 15 whereby said curved surface has the substantial egg shape . this provides bristles 14 of varying lengths relative to the outer surface . however , it is generally understood that the bristles terminate in a substantially linear fashion relative to the absolute center of the brush . egg shape allows the hair around to curl titer especially around the edges where the diameter is smaller then the middle . additionally , the brush 10 is constructed and arranged with interchangeable caps on either end of the barrel . these caps are integral in their configuration as they assist in various aspects of brush usage . one cap 11 has comb ( rake ) teeth 12 on it while the other cap has a smooth surface . the comb cap is used for parting the hair . the caps keep a section of hair in contact with the bristles . brushes without caps such as these can have sections of hair exit prematurely off either or both peripheral edges of the bristle section . in maintaining hair on the bristles , there is a greater efficacy in in styling and blow - drying hair . the styling and blow - drying is typically done in sections and the cap configuration provides a physical and visual aid in maintaining sections during these operations . the cap 11 is further configured as a hair - parting device . conventionally , a brush is changed for a comb or other implement when forming a hair part . the cap 11 of the present invention eliminates the need for such changes by allowing the leading edge to be used to form a part . one cap ( fig3 ) has comb teeth for separating the hair like a comb , by pivoting the brush it separates the volume of hair in a precise manner . it allows friction between the cap and the scalp that results in easier parting for both professionals and home use . as seen in fig8 thumbrest 20 , in one embodiment , is coated with a satin rubber finish for grip . additionally , thumb rest has a plurality of indentations that provide for improved grasping by a user . the thumb rest configuration naturally fits the contour of the thumb and makes it easy to manipulate the brush with less thumb fatigue . in one embodiment , the invention has incorporated grip beads on the thumbrest for a better non - slip grip and a rubber texture . while the invention has been described in its preferred form or embodiment with some degree of particularity , it is understood that this description has been given only by way of example and that numerous changes in the details of construction , fabrication , and use , including the combination and arrangement of parts , may be made without departing from the spirit and scope of the invention .
the present invention provides a hairbrush having a handle , a brush support screen dependent on said handle ; and a plurality of bristles extending outward through said screen , wherein said screen is constructed and arranged in a substantially egg shaped geometry
