Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation in part of U.S. patent application Ser. No. 11/431,310 filed May 10, 2006 and U.S. patent application Ser. No. 11/364,592 Filed Feb. 28, 2006, both of which are incorporated by reference herein in their entirety.

FIELD OF THE INVENTION

The present invention relates to a self-cleaning heatable hair styling brush that removes hair from the bristles of a hair styling brush in a thorough and convenient manner which also incorporates the use of colour changing agents that when heated change the colour/appearance of the styling/cleaning element(s) to further indicate hair styling brush readiness for use to the user.

BACKGROUND OF THE INVENTION

Hair styling brushes are notoriously difficult to clean. The more bristles a hair styling brush has, perhaps the more effective the hair styling brush is as a tool, but also, the more difficult it is to clean. The use of hair styling brushes with self-cleaning capabilities of known designs and configurations is known in the prior art. More specifically, hair styling brushes with self-cleaning capabilities of known designs and configurations previously devised and utilized for the purpose of cleaning matter from the bristles of hair styling brushes through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

In addition the use of hair styling brushes with colour changing capabilities of known designs and configurations is also known in the prior art. More specifically, hair styling brushes with colour changing capabilities of known designs and configurations previously devised and utilized for the purpose of indicating readiness of use of said hair styling brush.

By way of example, U.S. Pat. No. 6,631,831 to Loiselle discloses a retractable bristle brush for removing hair from hair brushes. U.S. Pat. No. 5,862,563 to Hartmann discloses a removable cleaning plate for removing hair from hair brushes. U.S. Pat. No. 4,084,282 to Calvert discloses a power operated rotary brush for removing hair from hair brushes. U.S. Pat. No. 5,911,226 to Vecchioala discloses a hairbrush the surface of which changes colour with temperature.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a self-cleaning heatable hair styling brush that allows automatically removing hair from the bristles of a hair brush in a thorough and convenient manner in addition to the use of colour changing agents that when heated change the colour/appearance of the styling/cleaning element(s) to further indicate readiness for use to the user.

In this respect, the self-cleaning heatable hair styling brush according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of automatically removing hair from the bristles of a hair styling brush in a thorough and convenient manner in addition to the use of colour changing agents that when heated change the colour/appearance of the styling/cleaning element(s) to further indicate hair brush readiness for use to the user.

Therefore, it can be appreciated that there exists a continuing need for a new and improved self-cleaning heatable hair styling brush, which can be used for automatically removing hair from the bristles of a hair brush in a thorough and convenient manner with heatable styling/cleaning element(s) that change colour when heated to further indicate hair brush readiness for use. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of hair styling brushes with self-cleaning capabilities of known designs and configurations now present in the prior art, the present invention provides an improved self-cleaning hair styling brush with heatable styling/cleaning element(s). As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved self-cleaning heatable hair styling brush with heatable styling/cleaning element(s), which has all the advantages of the prior art and none of the disadvantages.

To attain this, the present invention is a hair styling brush with sliding parts (styling/cleaning element) for hair removal. The hair styling brush has a brushing element supporting a plurality of bristles and a styling/cleaning element having openings through which the bristles protrude. To use the brush, as a regular hair brush, the styling/cleaning element can be positioned at various distances from the brushing element to affect long or short bristles. To use the brush, as a hair styling brush, the styling/cleaning elements are heated with external hot air heat to a certain temperature and then also can be positioned at various distances from the brushing element to affect long or short bristles. To heat the hair styling brush, the styling/cleaning element is fully extended (maximum heating/cleaning position) away from the brushing element so that styling/cleaning plates are positioned at the tips of the bristles. External hot air heat is then applied to the styling/cleaning plate(s) until the styling/cleaning plate(s) changes colour/appearance further indicating hair brush readiness for use. The styling/cleaning element is then re-positioned to one of the various use positions. To clean the hair brush, the styling/cleaning element is fully extended (maximum heating/cleaning position) away from the brushing element so that any hairs entwined in the bristles are forced to or off the tips of the bristles. The brushing element has a hollow body and the styling/cleaning element is supported by a plate lifter (rib arm) which is attached to the control element/slide plate that is disposed within the brushing elements hollow body.

The hair styling brush has a control element used for adjusting the styling/cleaning element to the various brushing positions and the styling/cleaning position. Adjustment of the control element moves the styling/cleaning element relative to the brushing element. Specifically, the control element pulls the plate lifter (rib arm) within the brushing element propelling outward or inward until the styling/cleaning element is in the desired position relative to the bristles. In one embodiment of a brush in accordance with the invention, a spring assembly means is provided for elastically urging the styling/cleaning element(s) inwardly along the direction of the bristles, thereby speeding the return of the styling/cleaning element(s) to a use position following a cleaning of the brush. In another embodiment, the brush includes a sleeve/spacer assembly means for elastically urging the styling/cleaning element(s) inwardly along the direction of the bristles. A control element can be operable in both the lock means for releasably and lockably selecting and the sleeve/spacer means. The control element can be operable along the long direction of the brush. It is also contemplated that the control element can enable a ready positioning of the styling/cleaning element(s) to establish at least the first and second use-lengths of the bristles.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

The same reference numerals refer to the same parts throughout the various Figures.

The control element 18 forms the end part of the handle 14 of the hair brush. It has a round shape corresponding to the shape of the handle 14 of the brushing element 2. There are notched 34 steps inside the handle 14 of the brushing element 2. The end of the handle 14 where the control element 18 rests is numbered 0 through 5. These numbers 40 identify the different levels of notched 34 steps located inside of the handle 14. These notches 34 receive the parallel shaft 32 as set by the user in one of the six notches 40.

Referring to FIG. 4, heating the brush, the brush can be heated by pulling the control element 18 outward to the maximum heating/cleaning position. Pulling the control element 18 outward pulls the plate lifters/rib arms 28 outward which move the styling/cleaning plate(s) 16 outward to the tips of the bristles 12. The control element is guided within the body of the brushing element 2. When the control element 18 is forward, the styling/cleaning plate(s) 16 of the styling/cleaning element 4 is approximately even with the tips of the bristles 12, such that the outer surface of the styling/cleaning plate(s) 16 clears the tips of the bristles 12 while the inner surface of the styling/cleaning plate(s) 16 remains engaged with the tips of the bristles 12. Thus the styling/cleaning plate(s) 16 are now in position to be heated by an externally sourced apparatus that provides hot air heat to a temperature not exceeding 175 degrees Fahrenheit. When the desired temperature is reach the styling/cleaning plate(s) 16 change colour to indicate hair brush readiness for use. As a result the control element 18 is now either returned to a brushing position, where the bristles 12 protrude through the styling/cleaning plate(s) 16, by pushing inward the control element 18 which is guided within the handle 14 of the brush element 2 until the styling/cleaning plate(s) 16 are flush with the brushing element 2, or, one of the multiple brushing positions.

Referring to FIG. 4, after using the brush, the brush can be cleaned by pulling the control element 18 outward. Pulling on the control element 18 outward pulls the sleeve element 26 and plate lifters/rib arms 28 outward which moves the styling/cleaning plate(s) 16 outward to the tips of the bristles 12. The control element is guided within the handle 14 of the brushing element 2. When the control element 18 is forward, the styling/cleaning plate(s) 16 of the styling/cleaning element 4 is approximately even with the tips of the bristles 12, such that the outer surface of the styling/cleaning plate(s) 16 clears the tips of the bristles 12 while the inner surface of the styling/cleaning plate(s) 16 remains engaged with the tips of the bristles 12. Thus the styling/cleaning plate(s) 16 pushes any hairs that were entwined in the bristles 12 to the tips of the bristles 12 where hairs fall off or are removed. As a consequence the present design provides a means for varying a useful-length of respective bristles 12 and for cleaning bristles 12 using the presently noted styling/cleaning plate(s) 16, at least in part. The control element 18 is returned to a brushing position, where the bristles 12 protrude through the styling/cleaning plate(s) 16, by pushing in control element 18 back into the handle 14 of the brush element 2.

Referring now to FIG. 5, wherein a partial cross-sectional view along line 5-5 in FIG. 4 notes bristles 12 extending radially outwardly from a central portion of brush head element and hollow body 10. As can also be seen from reviewing FIG. 3, cantilever portions extending from styling/cleaning plate(s) 16 contact respective plate lifters/rib arms 28 and move styling/cleaning plate(s) 16 radially outwardly along the direction of each bristle.

Those of skill in the art will appreciate that openings 20 may be of any shape effective to achieve the goals of the present invention. As a consequence of this realization, while holes 20 are shown to be substantially circular in FIG. 3, those of skill in the art will appreciate that various shaped openings may be used, including oblong, ovoid, rectilinear, tapered along a depth of styling/cleaning plate(s) 16, and other shapes effective to both clean hair from bristles 12 and minimizing flexing of bristles 12 during a motion of styling/cleaning plate(s) 16 along the length of each bristle. As a consequence, it will be appreciated in FIG. 5, that styling/cleaning plate(s) 16 are not intended to cause flexing of bristles 12 during operation, thus improving hair removal and bristle life.

It will also be noted from FIG. 5, that where styling/cleaning plate(s) 16 end along a row of bristles 12, holes 20 may partially exist on each respective styling/cleaning plate (for example as a %-circle or semi-ovoid). Thus, as noted in FIG. 1, styling/cleaning plate(s) 16 may have joints between rows of bristles 12, and as noted in FIGS. 4 and 5, styling/cleaning plate(s) 16 may have joints that end on a row of bristles 12, all without departing from the scope and spirit of the present invention. Since styling/cleaning plate(s) 16 operate along a length of respective bristles 12 either construction will operate effectively to remove hair and to moderate/adjust a useful bristle length, as will be discussed below.

The brush has multiple brushing/styling positions. The styling/cleaning element 4 can be raised so that its styling/cleaning plate(s) 16 is/are substantially flush with the body 10 of the brushing element 2. In this position, the bristles 12 are at their full length. To set the brush to this first brushing/styling position, the parallel shaft 32 is positioned within the lowest of the notched 34 steps. The parallel shaft 32 is set by pulling and turning the control element 18 in the appropriate direction to the targeted notch 34. Upon release of the pressure, the parallel shaft 32 engages within one of the notches of the handle 14. In addition, the styling/cleaning plate(s) 16 can be adjusted to a plurality of intermediary fixable positions between the first brushing position (FIG. 1) and the heating/cleaning position (FIG. 4). For example, the four intermediary positions set the styling/cleaning plate(s) 16 at varying distances, e.g. ⅕ and ⅖ distance from the body 10. The effect of the intermediary positions is to vary the usable and operable length of respective bristles 12, i.e. long, medium and short.

Referring now to FIG. 7, when the parallel shaft is set to the notch 1, the styling/cleaning plate(s) 16 is/are secured away from the body 10 at a distance of approximately ⅕ the full length of the bristles. Setting the parallel shaft 32 to level 1 effectively reduces the bristles 12 to a short length. The combination of the parallel shaft 32 and the notched 34 opening forms a locking mechanism because when the parallel shaft 32 is disposed within any of the notches 34, the styling/cleaning element 4 is locked in position relative to the control element 18.

From any brushing/styling position the brush can be cleaned by pulling the control element 18 outwardly away from the brush head, which in turn moves the styling/cleaning element 4, styling/cleaning plate(s) 16 to the tips of the bristles 12 thereby removing the entangled hairs. After cleaning the brush, the styling/cleaning plate(s) 16 of the styling/cleaning element 4 are returned to a brushing/styling position by pushing the control element 18 inward to the desired bristles 12 length.

As a consequence of the present description, in combination with the drawings, it should be readily understood by those of skill in the art that an operation of the styling/cleaning elements relative to the brushing elements enables a mechanism or system for stripping or removing loose hair from bristles 12 in a direction substantially parallel to a bristle direction without requiring a bending or flexing of the bristles thereby minimizing a bristle flex stress during a cleaning step. As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the part of the inventions, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

In the claims, means- or step-plus-function clauses are intended to cover the structures described or suggested herein as performing the recited function and not only structural equivalents but also equivalent structures. Thus, for example, although a nail, a screw, and a bolt may not be structural equivalents in that a nail relies on friction between a wooden part and a cylindrical surface, a screw's helical surface positively engages the wooden part, and a bolt's head and nut compress opposite sides of a wooden part, in the environment of fastening wooden parts, a nail, a screw, and a bolt may be readily understood by those skilled in the art as equivalent structures. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
