Description
FIELD OF THE INVENTION
The present invention relates to brushes. More particularly, the invention relates to a hairbrush having housed therein a radio receiver for providing audio entertainment during the hair brushing task.
BACKGROUND OF THE INVENTION
In the past, sound generators or radio receivers have been incorporated into a vast array of devices for personal entertainment or even to encourage proper habits through reward. Although proper maintenance of the hair is important for general hygiene, however, there has been very little development toward the incorporation of audio devices into hairbrushes or the like. Because the task of hair brushing often involves water and/or other hair care products, the incorporation of electrical devices has previously been limited to simple devices that are easily sealed within a brush structure. For example, U.S. Pat. No. 5,924,159 issued Jul. 20, 1999 to Haitin (“Haitin”) discloses a brush having a sound generator that rewards brushing movements of a certain speed, force and duration. Haitin, which is limited to very simple output, however, does not extend to the incorporation of more sophisticated entertainment providing structures. Likewise, U.S. Pat. No. 4,641,014 issued Feb. 3, 1987 to Bland (“Bland”) discloses a hand held hair dryer with a housed radio receiver. The dryer of Bland, however, does not contact wet hair or flowing water and thus does not include those features necessary to the incorporation of a radio receiver within a hairbrush.
It is therefore a specific object of the present invention to incorporate a radio receiver into a conventional hairbrush, whereby the user may have the benefits of audio entertainment to relieve the tedium of hair brushing notwithstanding the generally incompatible environment presented by the task. It is a further object of the present invention to provide such a hairbrush in a compact and convenient form that is also economical to produce.
SUMMARY OF THE INVENTION
In accordance with the foregoing objects, the present invention—a radio hairbrush—generally comprises a body, having a plurality of bristles dependently secured thereto; a handle; a radio receiver integral with the body; and an audio output device. The radio receiver is contained within a cavity internal to the body and all controls for the radio receiver are sealed to prevent the ingress of fluids to the cavity. Preferably, the controls include at least an ON-OFF control for the radio receiver and a volume control for controlling the level of sound generated by the audio output device.
In at least one embodiment of the present invention, a plurality of orifices through the body are positioned adjacent to the audio output device for allowing the emanation through the body of sound waves emitted from the audio output device. In this embodiment, a flexible membrane, such as a thin, plastic sheet, is interposed between the audio output device and the orifices to prevent the ingress of fluids through the orifices to the cavity.
The handle preferably comprises a compartment adapted to retain a power source, such as one or more batteries, for the radio receiver. The handle further comprises a removable cap, for allowing access to the compartment for placement and/or removal of the battery or batteries, which is adapted to form a watertight seal to the compartment. In at least one embodiment, this seal may be achieved by placement of a gasket, O-ring or other like structure adjacent to or within the cap.
Finally, many other features, objects and advantages of the present invention will be apparent to those of ordinary skill in the relevant arts, especially in light of the foregoing discussions and the following drawings, exemplary detailed description and appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Although those of ordinary skill in the art will readily recognize many alternative embodiments, especially in light of the illustrations provided herein, this detailed description is exemplary of the preferred embodiment of the present invention, the scope of which is limited only by the claims appended hereto.
Referring now to the Figures, the preferred embodiment of the present invention—a hairbrush
15
with integral radio receiver
10
, generally comprises a handle
11
, a body
12
, a radio receiver
13
and an audio output device
14
, such as for example, a speaker. According to the preferred embodiment, the handle
11
is integrally formed with, or otherwise secured to, the body
12
of the hairbrush
15
. The body
12
of the hairbrush
15
, as will be better understood further herein, fully encloses the radio receiver
13
and audio output device
14
. In this manner, the electrical components
16
of the present invention may be protected from water and/or hair care products. Additionally, the batteries
17
for operation of the radio receiver
13
are preferably conveniently housed within the handle
11
. As a result, the hairbrush
15
is adapted to provide a compact and convenient entertainment source, particularly suited to relief of the brushing tedium. It is expected that this combination will, especially among younger users, greatly encourage more thorough and frequent brushing by the addition of a fun element to an otherwise time-consuming and laborious chore.
Referring now specifically to
FIG. 1
, the body
12
of the hairbrush
15
is shown to generally comprise a plurality of bristles
18
dependently secured adjacent one side of a substantially fluid impermeable body
12
. According to the preferred embodiment of the present invention, the body
12
is constructed of a plastic or like material, which is lightweight and inexpensive to manufacture yet generally fluid impervious. While those of ordinary skill in the art will recognize many possible substantial equivalents, it is only critical that such substitutions provide a water resistant housing for the radio receiver
13
and audio output device
14
. As a result, all such substitutions should be considered within the scope of the present invention, which is limited only by the claims appended hereto. Likewise, the bristles
18
may comprise any of a number of materials such as, for example, wire or plastic, although they should in any case be constructed and operative as are those of an ordinary hairbrush. Because it is preferred that the cavity
19
internal the body
12
be fluid impermeable, however, in order to protect the various components
16
of the radio receiver
13
from damage, the bristles
18
should be secured to the body
12
in a manner that precludes the infusion of fluids through their points of affixation. This may be accomplished, for example, by securing the bristles
18
into indentations in said body
12
that do not fully penetrate the body
12
or, in the alternative, by filling orifices of affixation with an epoxy resin or the like.
As also shown in
FIGS. 1 and 3
, the body
12
of the hairbrush
15
further comprises a plurality of orifices
20
for the transmission therethrough of sound waves, a power indicator
21
and a window
22
for indication of the selected radio station. To prevent the ingress of water and other fluids, thereby maintaining the integrity of the radio receiver
13
, a fluid impermeable membrane
23
is preferably interposed between the sound orifices
20
and the radio receiver
13
. Such a membrane
23
may comprise, for example, a thin sheet of plastics material circumferentially adhered to the internal surface of the body
12
about the extent of the sound orifices
20
. The power indicator
21
, which may comprise a light-emitting diode (“LED”) or the like, is also preferably placed in sealed engagement with the body
12
of the hairbrush
15
. Such sealed engagement may be achieved, for example, by placing an epoxy resin around the glass or plastic circumference of the indicator
21
and in sealing contact with the circumferential extent of the orifice therefor. In the alternative, the indicator
21
may be positioned within the cavity
19
in the area of a translucent window integral with and through the body
12
. In this manner, a power on condition may be indicated to the user, thereby preventing inadvertent battery drainage without compromise to the fluid resistant integrity of the present invention. Finally, a tuning window
22
is similarly provided in the body
12
of the hairbrush
15
so that the user may readily tune the receiver
13
to a desired station.
Referring now to
FIG. 2
particularly, the radio receiver
13
of the hairbrush
15
is further detailed. According to the preferred embodiment of the present invention, the radio receiver
13
, which may comprise a standard AM-FM receiver modified in accordance with teachings herein, is securely mounted within the body's internal cavity
19
. An integral ON-OFF-VOLUME control
24
, a tuning control
25
, a tuning scale
26
and an AM-FM control
27
, as are well known to those of ordinary skill in the electrical arts, are provided. Although those of ordinary skill will recognize that separate power and volume controls may be provided, it is preferred that an integral control
24
be utilized in this application to minimize the opportunity for fluid ingress. In the preferred embodiment of the present invention, each exteriorially extending control
24
,
25
,
27
of the radio receiver
13
are selected to be fluid resistant while the antenna for the radio receiver is implemented in a low profile form for mounting entirely within the cavity
19
. Each of these components
24
,
25
,
27
are readily available to those of ordinary skill in the art. For example, many manufacturers produce button-type single or double pole, single or double throw switches in weatherproof and/or water tight designs. Exemplary of these manufacturers are Clarostat of El Paso, Tex.; Honeywell of Freeport, Ill.; and NKK Switches of Scottsdale, Ariz. In the alternative, other manufacturers, such as APM Hexseal of Mesa, Ariz., produce rubber boots and seals in many standard or custom forms for weatherproofing standard, off-the-shelf switches and rotary selectors.
Referring now to
FIG. 3
, the handle
11
of the radio hairbrush is shown to comprise a mute switch
28
, for convenient audio disruption and a battery compartment
29
. The mute switch
28
may be used to temporarily interrupt the receiver's audio output, for brief conversation or the like, without interrupting the brushing task. According to the preferred embodiment of the present invention the handle
11
of the hairbrush
15
is also constructed of a plastic or like material for protection of the batteries
17
and electrical components internal thereto. As also shown in the Figure, electrical wiring
30
connects the radio receiver
13
to the power source, which may typically comprise two standard 1.5 V alkaline or rechargeable batteries
17
connected in series retained within a battery compartment
29
by a cap
31
. The cap
31
is preferably sealed with an O-ring
32
or the like, which may comprise a rubber, polymeric or other similar material, to prevent the ingress through the battery compartment
29
of water or other fluids.
While the foregoing description is exemplary of the preferred embodiment of the present invention, those of ordinary skill in the relevant arts will recognize the many variations, alterations, modifications, substitutions and the like as are readily possible, especially in light of this description, the accompanying drawings and claims drawn thereto. For example, those of ordinary skill in the art will recognize that the radio receiver
13
may be replaced with a miniature compact disc player, cassette player, MP-3 player or the like. In the case of the MP-3 player, or other digital storage medium, the audio download may be through a translucent window utilizing an infrared interface or the like. Likewise, the handle
11
of the hairbrush
15
may be provided with an externally projecting charging plug, thereby allowing the permanent sealing of the batteries
17
within the handle
11
to further ensure that fluids do not ingress to the cavity
19
of body
12
. The only critical aspect for each of the foregoing examples, however, is that care be taken to protect the internal electrical components from fluids and other hair care products. In any case, because the scope of the present invention is much broader than any particular embodiment, the foregoing detailed description should not be construed as a limitation of the scope of the present invention, which is limited only by the claims appended hereto.
