Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to improvements in air conditioned headwear,
and more particularly, but not by way of limitation, to a removable
or independent air conditioning unit for use with with
substantially any headwear, such as caps, hats, headbands,
eyeglasses, and the like.
2. Description of the Prior Art
Persons spending a considerable amount of time in the out-of-doors,
such as workmen, athletes, sports fans, fishermen, and the like,
frequently wear head gear to protect themselves from the heat or
cold of the surrounding atmosphere. There is an ever increasing
demand today for providing the comfort of cooling of the wearer of
the head gear during hot weather conditions, or the like, or
heating of the wearer during cold weather conditions. Many air
conditioned hats, helmets, or the like, have been provided for
achieving these end results, such as those shown in the Julius Droz
U.S. Pat. No. 3,735,423, issued May 29, 1973, and entitled "Hat
With Ventilating Means", or my own prior U.S. Pat. Nos. 3,391,407,
issued July 9, 1968, and entitled "Helmet", and 3,548,415, issued
Dec. 22, 1970, and entitled "Air Conditioned Helmet". These devices
have certain disadvantages, however, in that the headwear is
provided with permanently installed air conditioning units, and in
the event there is no need or desire for using the air conditioning
unit, the headwear may be burdensome to wear. Other types of these
devices require that the headwear be altered in order to
accommodate the air conditioning unit.
SUMMARY OF THE INVENTION
The present invention contemplates an independent or detachable air
conditioning unit particularly designed and constructed for
overcoming the foregoing disadvantages, and which may be utilized
with substantially all types of headwear, such as hats, caps,
helmets, headbands, eyeglasses, and the like. The novel air
conditioning unit comprises an electric motor having an impeller or
fan carried thereby, and removably disposed within a lightweight
housing. The motor is preferably secured to an air inlet screen
which may be removably secured to or within the headwear. A battery
holder for receiving or supporting battery means is provided for
the unit and the battery is electrically connected with the motor
and an electric switch, which is also provided on the unit, and
operable to selectively actuate the motor and fan.
The air conditioning unit may be secured to or in substantially any
type of headwear in substantially any desired manner. For example,
outwardly extending tab means may be provided on the air
conditioning unit for insertion within recess means provided on the
head wear for removably securing the unit to the head wear.
Alternately, gripper means may be provided on the unit and the
headwear for removably securing the unit to the headwear, or Velcro
tape may be provided for securing the unit to the headwear, or
substantially any other type securing means may be provided. Thus,
the air conditioning unit may be quickly and easily installed on or
in the headwear when desired, and quickly and easily removed
therefrom when the headwear is to be otherwise used. The novel air
conditioning unit is of an overall lightweight construction,
preferably weighing not more than approximately three ounces, and
is simple and efficient in operation and economical and durable in
construction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings in detail, and particularly to FIGS. 1, 2
and 3, reference character 10 generally indicates an air
conditioning unit for headwear comprising a housing 12 preferably
constructed from a lightweight plastic material, but not limited
thereto. As shows in FIGS. 1, 2 and 3, the housing 12 comprises a
first substantially flat plate member 14 of a substantially
circular configuration, but not limited thereto, and having a pair
of oppositely disposed radially outwardly extending flaps or ears
16 and 18 preferably integral therewith. The central portion of the
plate 14 is provided with a plurality of openings or apertures 20
whereby air may pass through the plate for a purpose as will be
hereinafter set forth. In addition, a plurality of suitable
batteries 22, preferably two, but at least one or more, are
removably disposed in individual battery holders or brackets 24
mounted on or integral with the outwardly directed face of the
plate 14 in any well known manner (not shown). A suitable switch
member 26 is also mounted on the outwardly directed face of the
plate 14 in any suitable manner and is electrically connected
between the batteries 22 and a motor 28 for selective actuation of
the motor.
A second substantially flat plate 30 is spaced from the plate 14 by
a plurality of spaced support members 32, and the plate 30 is
preferably provided with a plurality of openings 34 including a
central opening 36 as particularly shown in FIG. 3. Thus, the plate
30 is of a substantially grid-type configuration whereby a stream
of air may flow therethrough. The plate 30 may be constructed from
a suitable lightweight plastic material, or may be constructed from
a suitable mesh-like material, such as a screen (not shown), and
functions as a grid for dispersing a flow of air therethrough. The
plate 30 may be a temperature grid, if desired, for either warming
or cooling the air passing therethrough, depending upon the desired
end result for the use of the unit 10. Or alternately, a separate
temperature grid (not shown) may be secured to one face of the
plate 30 in any well known manner, to provide a flameless warming
screen for heating the air passing therethrough, or may be a
refrigerant gel screen as set forth in my aforementioned pending
application for cooling the air passing therethrough.
The motor 28 extends inwardly from the plate 14 and may be of any
suitable type, such as a 1.5 volt motor, and carries a fan or rotor
38 which is disposed between the screens or plates 14 and 30. The
motor 28 and fan 38 are of a light-weight construction, and
preferably weigh, in combination, less than one ounce. In addition,
it is preferably that the fan 30 comprise blades made from a soft
plastic material whereby the rotation of the blades may be stopped
easily and harmlessly with a finger of the user of the unit 10. The
fan 26 is rotated by the motor 28 in the usual manner and pulls air
into the housing 12 through the first plate 14 and discharges air
from the housing 12 through the screen or plate 30. Of course, the
fan 38 is only activated when the switch 26 has been properly
manipulated, as is well known.
As hereinbefore set forth, the battery or batteries 22 may be of
any suitable type as required for supplying power to the motor 28,
such as 1.5 volt dry cell batteries, but not limited thereto. The
switch 26 may be of any suitable type, such as a toggle switch,
push button type, or the like, for ready manipulation by the user
of the unit 10 in order to selectively start and stop the operation
thereof. The bracket or brackets 24 are preferably provided with
the usual electrical contacts (not shown) for engagement with the
opposite ends of the batteries 22, as is well known. One of said
electrical contacts is electrically connected with the motor 28 by
a lead 40 (FIG. 1) and the opposite electrical contact of the same
bracket 24 is electrically connected with one contact of the other
bracket 24 by a lead 42. The remaining contact is electrically
connected with the switch 26 by a lead 44, and the switch 26 is
electrically connected with the motor 28 by a lead 46. This places
the switch 26 whereby one position thereof electrically connects
the battery or batteries 22 with the motor 28 for actuation
thereof, and another position of the switch 26 breaks the
electrical connection between the battery or batteries 22 and the
motor 28. Of course, the fan 38 is rotated continuously during the
activation of the motor 28 for moving air through the housing 12
for discharge thereof through the panel or plate 30.
The air conditioning unit 10 may be removably secured to
substantially any type headwear in any well known manner. However,
as shown in FIGS. 1, 2 and 3, the flaps or ears 16 and 18 are
particularly designed and constructed for a removable engagement
with suitable pockets one of which is shown at 17 in FIG. 9 or
recesses which may be provided on the headwear in any well known
manner. Thus, the unit 10 may be quickly and easily installed on
the headwear without substantial alteration of the overall
appearance thereof when it is desired to heat or cool the air
directed over the users head or across his face and forehead. The
unit 10 may also be quickly and easily removed from the headwear
when it is not needed, and the headwear may be utilized in its
normal fashion.
For example, as schematically depicted in FIG. 7, the unit 10 may
be removably secured within a helmet 48 in the manner as
hereinbefore set forth, and may be utilized for heating or cooling
air for discharge of the air into the head (not shown) of the
wearer of the helmet. By way of further example, the unit 10 as
shown in FIG. 8 may be removably secured to a sweat band or
independent headband 50 in such a manner that the plate 30 is
disposed against the forehead, or the like, of the person using the
apparatus 10. Of course, substantially any type of device for
wearing on the head may be provided with the unit 10 in order to
direct warm or cool air onto the head, or any portion thereof, or
onto the shoulders, or the like, of the person using the device
10.
Referring to FIG. 4, another embodiment of the invention is
generally indicated at 52 and comprises a substantially
semi-spherical housing 54 constructed from a suitable lightweight
plastic material, or the like, and having a grid-type or open
construction as clearly shown in the drawings. The open end 56 of
the housing 54 is substantially closed by a plate or disc member 58
which may be generally similar to the plate 14, but not limited
thereto. In this embodiment, the unit is provided with at least
one, and preferably two, but not limited thereto, batteries 60
removably disposed in individual battery holders or brackets 62
which are secured to or integral with the outer face of the plate
58 in any well known manner. A motor 64 generally similar to the
motor 28 is secured to the central portion of the plate 58 in any
well known manner, and a switch 66 is also secured to the plate 58
in the same general manner as the switch 26. The switch 66 is
electrically connected between the battery or batteries 60 and the
motor 64 as hereinbefore set forth in order to provide selective
actuation of the motor 64. In addition, a fan or rotor 68 similar
to the fan 38 is carried by the motor 64 and rotates continuously
when the switch 66 is in the "on" position, as is well known.
It will be readily apparent that the unit 52 may be quickly and
easily installed in substantially any type of gear worn on the
head, as hereinbefore set forth, and quickly and easily removed
therefrom when the unit 52 is not required.
Referring now to FIG. 5, still another embodiment of the invention
is generally indicated at 70, and as shown herein comprises a
housing 72 which includes a first substantially elongated plate
member 74 of a lightweight construction and of a grid-type
configuration. Power means, such as a battery 76, is suitably
secured to the outwardly directed face of the plate 74, and is
electrically connected between a switch 78 and motor 80 which are
also mounted on the plate 74. Of course, the electrical connection
between the switch 78, motor 80 and battery 76 may be of any
suitable or well known type whereby the motor 80 is activated only
when the switch 78 is in the "on" position.
A second plate 82 is spaced from the first plate 74 by a plurality
of spaced support members 84, and is preferably of an elongated
grid-type configuration. As hereinbefore set forth, the plate 82
may be a temperature grid, if desired, or an independently
temperature grid (not shown) may be disposed adjacent or secured to
the plate 82 for warming or cooling any air passing through the
plate 82. A fan 86 is carried by the motor 80 and is generally
similar to the fan 38 for pulling air through the plate 74 and
discharging air through the plate 82, as hereinbefore set
forth.
As particularly shown in FIG. 5, the unit 70 may be removably
installed in the bill 88 of a cap 90 in any suitable manner, such
as a projection or knob member 91 secured to the unit 70 and
removably engagable with an elastic band 93 or the like secured to
the bill 88, without any substantial alteration of overall
configuration of the cap. Thus, the cap 90 may be easily worn in
its natural condition when the unit 70 is not required.
Referring now to FIG. 6, still another embodiment of the invention
is shown wherein an air conditioning unit generally indicated as 92
is shown. The unit 92 comprises a small motor 94 of the same
general type as the motor 28 removably secured in an opening 96
provided in the bridge portion 98 of a pair of eyeglasses 100. A
fan 102 is carried by the motor 94, and as shown in FIG. 6 is
disposed exteriorly of the eyeglass portion 104 of the eyeglasses
100. Thus, the fan will pull fresh air onto the forehead or face of
person wearing the glasses 100 having the unit 92 removably
installed thereon. It will be readily apparent that the fan 102 may
be disposed interiorly of the eyeglass portion 104, if desired, and
a suitable guard plate, or the like, (not shown) may be provided
between the fan 102 and the anatomy of the person wearing the
glasses 100. In addition, at least one and preferably two batteries
106 (shown in broken lines) are removably secured to the frame
portion 108 of the glasses 100, and a switch 110 is also removably
secured to the frame 108 in any suitable manner (not shown). Of
course, the switch 110 is electrically connected between the
battery or batteries 106 and the motor 94 whereby the fan 102 may
be selectively rotated by manipulation of the switch 110.
It will be apparent that the entire unit 92, including the motor
94, fan 102, and battery means 106, may be removably attached to
substantially any normal or standard type eyeglasses. The means for
removably securing the unit 92 to the eyeglasses may be of any
suitable type such as clasps, clips, snaps, or the like (not
shown).
It is to be understood that substantially any well known or
desirable means may be provided for removably securing the unit 10,
or other air conditioning units of the invention, to the headwear,
or gear worn on the head or any portion thereof, such as Velcro
tape, gripper means, zipper elements, or the like (not shown). In
addition, headwear constructed from soft or flexible materials in
the proximity of the desired mounting location for the unit 10 may
be reinforced with any desired and well known material for
facilitating the installation or attachment of the unit 10 to the
headwear.
As hereinbefore set forth, the unit 10 may be utilized in
combination with substantially any type headwear. It is to be
noted, however, in each instance it is desirable to arrange the
unit 10 on the headwear in such a manner that the air blowing from
the detachable or removable unit moves onto the head, or any
portion thereof such as the forehead, neck, shoulders, face, or the
like, of the wearer. The draft of moving air is useful and
advantageous not only for cooling, but also to blow away air
pollutants, mosquitoes, flies, insects, and the like, even when the
downwardly or otherwise flowing air is not additionally cooled or
warmed by the temperature control plate 30. It has been found that
the moisture frequently on the skin of the wearer in the form of
perspiration aids in the cooling of the wearer as the moving air
passes across the damp skin area or areas.
Whereas the invention as particularly described herein includes the
use of a conventional electric motor, it is to be understood that
substantially any other type of power means may be utilized in lieu
thereof. For example, solar cells may be secured in the units in
such a manner that the housing of the unit may become the collector
surface for solar energy for use as the power for the units, or
alternately, the solar cells may be secured to the headwear in such
a manner that a portion of the headwear may be utilized as the
collector surface therefor. In addition, whereas the band 50 as
illustrated in FIG. 8 has been referred to as a headband, it is to
be noted that the band 50 may be of a type to be worn about the
neck of the user, or any portion of the anatomy wherein it is
desired to provide a cooling or warming flow of air. Of course, in
the event the removable air conditioning unit is utilized in
combination with eyeglasses, the air current blowing directly onto
the glass portion thereof substantially precludes loss of vision
due to "fogging" when cold glasses are exposed to warm air, or by
loss of vision by smoke, or the like, which may be blown away by
the fan. In addition, it is anticipated that the open framework of
the eyeglasses may be utilized in the manner as hereinbefore set
forth even in the event that no glass is installed therein. The
novel air conditioning unit may also be of a "snap-on" type
construction for installation on substantially any normal type of
eyeglasses.
It is also anticipated that the air conditioning unit of the
invention may be affixed in a self-contained fashion to a
"walkie-talkie" helmet, to ear and hearing protector devices, such
as used by airplane controllers on the ground at airports, and the
like. Thus, the novel air conditioning unit of the invention makes
