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
air conditioning unit for use with substantially any headwear.
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
Pat. No. 3,735,423, issued May 29, 1973, and entitled "Hat With
Ventilating Means", or my own prior Pat. No. 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.
SUMMARY OF THE INVENTION
The present invention contemplates a detachable air conditioning
unit particularly designed and constructed for overcoming the
foregoing disadvantages, and which may be utilized with
substantially all types of headwear. 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 secured to an air inlet screen which is removably inserted
within a recess or aperture provided at one end of the housing. A
battery holder for receiving or supporting a battery is provided on
the housing and the battery is electrically connected with the
motor and an electric switch, which is also provided on the
housing, and operable to selectively actuate the motor and fan. A
removable temperature control panel or grid is provided at the
opposite end of the housing spaced from the fan, and functions as a
cooling or warming means, in accordance with the requirements of
the wearer of the headwear.
The air conditioning unit may be secured to substantially any type
of headwear in substantially any desired manner. For example, a
thereaded air flow vent may be provided in the headwear for
threadedly receiving the air conditioning unit housing therein for
removabley securing the unit to the headwear. A cover plate having
complementary threads provided on the outer periphery thereof may
be inserted in the air vent at time when the air conditioning unit
is not required. Alternately, complementary gripper elements may be
provided on the headwear and the air conditioning unit for
removably securing the unit to the headwear. In this instance, a
cover member provided with complementary gripper elements may be
provided for attachment to the air vent at times when the air
conditioning unit is not required. 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 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. The housing 12 is preferably of a substantailly
semi-spherical or generally outwardly flaring configuration having
a longitudinally extending neck portion 14 at one end thereof open
at 16 for receiving an air inlet screen 18 therein. The air inlet
screen 18 may be of a mesh-type construction, a grid member, vented
plate, or the like, and is removably secured within the opening 16
in any suitable manner (not shown). The opposite end 20 of the
housing 12 is open and a temperature control panel 22 is removably
secured therein in any well known manner (not shown), however, it
is to be understood that the panel 22 may be permanently installed
in the open end 20, if desired. The temperature control panel 22
may be constructed from a suitable mesh-like material, such as a
screen, or may be of a grid-type construction, or the like, and
functions as either a warming means or cooling means, depending
upon the desired end result for the use of the unit 10. For
example, the panel 22 may be a refrigerant gel screen as set forth
in my aforementioned patents which cools the air passing
therethrough upon operation of the unit 10, or alternately, the
panel 22 may be a flameless warming screen which heats or warms the
air passing therethrough. Of course, the panel 22 may comprise a
ventilation screen only, permitting air to flow therethrough during
operation of the unit 10 for cooling by ventilation only.
A motor 24 is secured to the air inlet screen 18 in any well known
manner (not shown), and is disposed within the housing 12. The
motor 24 may be of any suitable type, such as a 1.5 volt motor, and
carries a fan 26 which is disposed between the screens 18 and 22.
The motor 24 and fan 26 are of a lightweight construction, and
preferably weigh, in combination, less than one ounce. In addition,
it is preferable that the fan 26 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 24 in the usual manner and pulls air
into the housing 12 through the air inlet 16 and discharges air
from the housing 12 through the temperature control panel or screen
22.
A suitable battery support bracket 28 is secured to the outer
periphery of the housing 12 for removably receiving a battery 30
therein. The battery 30 may be of any suitable type as required for
supplying power to the motor 24, such as 1.5 volt dry cell battery,
but not limited thereto. A suitable electric switch 32 is secured
to the housing 12 and extends outwardly therefrom as shown in FIG.
1. The switch 32 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 28 is preferably provided with the
usual electrical contacts (not shown) for engagement with the
opposite ends of the battery 30, as is well known. One of said
electrical contacts is electrically connected with the motor 24 by
a lead 34, and the other electrical contact is electrically
connected with the switch 32 by a lead 36. The switch 32 is also
electrically connected with the battery 30 by a lead 38. Thus,
placing of the switch 32 in one position electrically connects the
battery 30 with the motor 24 for actuation of the motor, and
placing of the switch 32 in another position breaks the electrical
connection between the battery 30 and the motor 24 for interrupting
the actuation of the motor 24. Of course, the fan 26 is rotated
continuously during the activation of the motor 24 for moving air
through the housing 12 for discharge thereof through the panel or
screen 22.
The air conditioning unit 10 may be removably secured to
substantially any type headwear in any well known manner. For
example, as shown in FIG. 1, the housing 12 may be provided with an
extension sleeve 40 extending longitudinally from the open end 20
thereof. The outer periphery of the sleeve 40 may be threaded as
shown at 42 for removable engagement with an internally threaded
vent member 44 which may be conveniently provided in the crown, or
the like, of a hat 46. The vent member 44 may be constructed from
any suitable material, such as a molded lightweight plastic
material, and secured to the body of the hat 46 in any well known
manner (not shown). When the unit 10 is desired for use in
connection with the hat 46, the sleeve 40 may be threadely secured
in the threaded vent 44. When the unit 10 is no longer required for
use in connection with the hat 46, the unit 10 may be quickly and
easily disengaged from the vent 44, and a complementary cover
member (not shown) having a threaded portion complementary with the
threaded vent 44 may be secured to the vent for enclosing the
opening, and permitting the normal use of the hat 46 without the
unit 10 in combination therewith.
Referring to FIGS. 2 and 3, an alternate means of securing the unit
10 to a hat 48 is shown wherein an outwardly extending
circumferential flange 50 is provided around the outer periphery of
the housing 12 in the proximity of the open end 20 thereof. A
plurality of gripper elements 52 are secured to the flange 50 in
circumferentially spaced relationship. A plurality of complementary
gripping elements 54 are spaced around the crown, or the like, of
the hat 48 for engaging the gripper elements 52 in order to
removably secure the unit 10 to the hat 48. In addition, an air
vent 56 is provided in the crown, or the like, of the hat 48 in
substantial alignment with the open end 20 of the housing 12, and a
screen 58, or the like, for ventilation, refrigerant cooling, or
flameless warming, is suitably secured in the vent 56 for passing
air therethrough into the interior of the hat 48. The hat 48 may be
used in the normal manner, without the unit 10. However, when it is
desired to provide additional cooling or warming for the wearer of
the hat 48, the unit 10 may be readily secured thereto by snapping
the complementary gripper elements 52 and 54 together in the usual
manner. Of course, the unit 10 may be quickly and easily removed
from the hat 48 by disengaging the connection between the gripper
elements 52 and 54 when it is no longer necessary to provide the
additional cooling or warming for the wearer of the hat.
It is to be understood that substantially any well known or
desirable means may be provided for removably securing the unit 10
to the headwear, such as Velcro tape, zipper elements, of 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 facilitaing 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 a reservoir of air
blowing from the detachable unit 10 moves downwardly onto the head,
neck and shoulder of the wearer. The draft of downwardly 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 flowing air is not additionally cooled or
warmed by the temperature control panel 22.
By way of example, FIGS. 4 through 10 illustrate typical headwear
with which the unit 10 may be efficiently and effectively utilized.
FIG. 4 discloses a cap 60 having the crown portion 62 thereof being
constructed from a suitable soft or flexible material, such as
cotton, or the like, but not limited thereto. A relatively stiff or
rigid bill or visor 64 extends outwardly from a portion of the
outer periphery of the crown 62 to provide a sunshade for the eyes
of the wearer, as is well known. A unit 10 may be removably secured
to the bill 64 in any well known manner, and as hereinbefore set
forth, said bill or visor 64 is provided with a suitable vent (not
shown) in alignment with the opening 20 of the unit 10. In this
embodiment, the switch 32 may be installed or mounted on the crown
portion 62 in the proximity of the unit 10 for facilitating manual
operation thereof as desired.
FIG. 5 illustrates a cap 66 which is preferably constructed of a
stiff or rigid material and includes a relatively rigid crown
portion 68 havng an integral visor or bill 70 projecting outwardly
therefrom for protecting the eyes of the wearer from sun glare. In
this type cap, the motor 24 and fan 26 may be mounted interiorly of
the crown 68, as shown in dotted lines, and the motor 24 may be
suitably secured to a sound-absorbent, flexible support (not
shown), such as rubber or the like, which may be secured within the
crown by suitable connection members 72, or may be removably
inserted into slots (not shown) molded or otherwise formed on the
inner periphery of the crown 68. The battery 30 and switch 32 may
be either exteriorly or interiorly mounted with respect to the
crown portion 68, as desired, and it is important to provide
sufficient spacing between the air screen 18 and the inner
periphery of the crown portion 68 to permit a free flow of air
during operation of the unit 10.
FIG. 6 relates to a cap 74 constructed from a relatively stiff or
rigid material and comprising a rigid crown portion 76 having an
integral visor or bill 78 provided thereon. A suitable vent (not
shown) may be provided in the rear portion or front portion of the
crown 76, as desired, and the unit 10 may be removably or
detachably secured to the crown portion 76 with the open end 20
thereof in alignment with the vent provided in the crown. When a
vent is provided in the front or the rear portion of the crown, it
may be desirable to provide at least one additional vent therein
for facilitating circulating of air during use of the unit 10. Of
course, a suitable cover member (not shown) may be installed in the
vent opening or openings in the crown 76 when the unit 10 is not
required, as hereinbefore set forth.
FIG. 7 illustrates still another type hat generally indicated at 80
and which preferably is constructed from a suitable soft or
flexible material. The hat 80 comprises a relatively soft or
flexible material. The hat 80 comprises a relatively soft crown
portion 82 having a brim 84 provided therearound, as is well known.
This type of hat is usually provided with a plurality of relatively
small vent ports as shown at 86. However, when it is found that the
ports 86 do not provide sufficient ventilation for comfort of the
wearer, a unit 10 may be removably secured thereto in the manner as
hereinbefore set forth. For example, the upper portion 88 of the
crown 82 may be reinforced with a suitable relatively stiff or more
rigid material (not shown) in any well known manner, and a suitable
vent (not shown) may be provided in the center of the top portion
88, as hereinbefore set forth. The unit 10 may be removably secured
to the top portion 88 in substantial alignment with the vent and
may be utilized as desired for adding to the comfort of the wearer.
The top portion 88 of the crown 82 may be provided with a threaded
vent, as herein before set forth, and a suitable cover may be
secured thereto when the unit 10 is removed; or the vent in the
portion 88 may be permanently installed ventilation screen similar
to that shown at 58 in FIG. 2, and may be used in the normal manner
when the unit 10 is removed from the hat 80.
FIG. 8 depicts still another embodiment wherein a substantially
rigid helmet 90 may be of any usual or standard type construction
and normally comprises a dome-type crown 92 having a brim 94
provided around the open lower portion thereof. As shown herein,
the helmet 90 is of the type particularly designed for female use,
and is provided with decorative netting 96, or the like, and the
material from which the crown 92 and brim 94 is constructed is a
relatively stiff open type or loose-weave appearing material, as
indicated in the drawing. The helmet 90, however, may be
constructed from a closed-type rigid material, and the decorative
features may be eliminated, if desired, since there is no intention
of limiting the use of the unit 10 to the particular helmet shown
in FIG. 8. A suitable vent (not shown) may be provided in the top
of the crown 92, or at any other desired location therein, for
removably receiving the unit 10 therein, and additional vents (not
shown) may be provided in the crown 92 for facilitating air
circulation as hereinbefore set forth. Helmets of this type lend
themselves to the installation of an internally threaded vent
opening as shown at 44 in FIG. 1, but there is no intention of
limiting the use of the unit 10 with this particular type
connection element when being installed in the helmet 90. Here
again, when the unit 10 is not required, the vent in the crown 92
may be closed by a suitable cover member (not shown) as hereinafter
set forth.
FIGS. 9 and 10 illustrate a substantially conventional helmet 96
constructed from a rigid type material and having the usual crown
98 provided with the usual integral brim 100 around the open lower
end thereof. The helmet 96 may be further provided with a centrally
disposed dome 102 at the top of the crown 98, said dome 102 being
of a configuration generally similar to or complementary with the
configuration of the housing 12 of the unit 10. An apertured air
vent 103 may be suitable rotatably installed or secured to an
apertured vent 105 provided in the upper end of the dome 102, and
the dome 102 and converging portion of the crown 98 therewith may
be utilized in lieu of the housing 12. The motor 24 and fan 26 may
be removably secured in the dome 102 spaced from the vent 105 in
any suitable manner. For example, as shown herein the motor 24 is
supported by a flexible mounting element 107 constructed of rubber,
or the like, and comprising a plurality of radially outwardly
extending fingers 109 having a central bore (not shown) at the
point of the juncture therebetween. The motor 24 is removably
mounted within the central bore, which is preferably provided with
inwardly directed flexible gripper members (not shown), and the
mounting element 107 is removably secured within the dome 102 by
insertion of the outer ends or extremities of the fingers 109 in
slots 111 provided on the inner periphery of the dome 102. The
rotatable vent 103 may be manually orientated with respect to the
vent 105 for opening the interior of the dome 102 to the
atmosphere, or alternately may be orientated with respect to the
vent 105 for closing the interior of the dome 102.
The temperature control panel 22 may be removably or permanently
secured at the juncture between the dome 102 and crown 98, as
desired, and as shown in FIG. 9, with the motor 24 and fan 26 being
mounted within the dome 102 between the vent 103 and panel 22, in
the manner as hereinbefore set forth. It is to be noted in this
instance it may be preferable to mount the battery 30 and switch 32
on a common bracket 106, or the like, to provide a "power pack" 108
which may be carried in the shirt pocket, or the like, of the
wearer. The power pack 108 may be provided with suitable leads 110
for connection with suitable terminals 112, said terminals being
mounted on the outer periphery of the helmet 96 and electrically
connected with the motor 24 in any well known manner. When the unit
10 is to be activated, it is preferable to open the vents 103 and
105, the power pack 108 may be electrically connected with the
motor 24 and fan 26 by connecting the leads 110 with the terminals
112 in the usual or well known manner, and the switch 32 may be
utilized for slective actuation of the motor 24 and fan 26. Whereas
the unit 10 thus installed or mounted within the dome 102 of the
helmet 96 may be removable, it is to be further noted that this
installation may be permanent, if desired, and it is considered
that the overall outer configuration of the helmet may become well
known in the identity thereof as being an air conditioned hat, in
the manner in which persons have become accustomed to seeing
window-type air conditioners installed in a residence or other
building.
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 directly to the
crown or other portion of the headwear whereby the surface of the
headwear becomes the collector surface for solar energy for use as
the power for the unit 10. In addition, the temperature control
panel 22 may be removably secured to the unit 10, or may be
permanently secured thereto, as desired. Alternately, the
temperature control panel 22 may be removably or otherwise secured
in the headwear itself rather than in the unit 10, as desired.
It is to be understood that any headwear having a unit 10 in
combination thereiwth may be provided with one or more vents in the
crown portion thereof for facilitating the circulation of air
during use of the unit 10. The vents may comprise a plurality of
relatively small ports, or a lesser number of larger ports, either
completely open, or having screen-like inserts, or the like,
therein. It is to be further understood that the unit 10 may be
removably installed on substantially any type headwear in any
desired location thereon, and is not limited to the particular
orientation disclosed herein.
From the foregoing it will be apparent that the present invention
provides a novel air conditioning unit which may be quickly and
easily installed or attached to substantially any type headwear,
and may be readily removed therefrom when the use of the unit is no
longer desired or necessary. The novel air conditioning unit
comprises a housing which may be removably secured to the headwear
at substantially any desired position thereon. An air screen is
carried by the housing and supports a motor and fan within the
housing, A temperature control panel is also carried by the housing
in spaced relation to the air screen whereby air is pulled into the
housing by the fan and discharged therefrom through the temperature
control panel for blowing cooled or warmed air downwardly over the
neck, face, and shoulders of the wearer. Power supply means is
operably secured to the motor and is provided with switch means for
facilitating the selective operation of the motor and fan by the
wearer of the headgear or headwear. The novel air conditioning unit
is simple and efficient in operation and economical and durable in
construction.
Whereas the present invention has been described in particular
relation to the drawings attached hereto, it should be understood
that other and further modifications, apart from those shown or
suggested herein, may be made within the spirit and scope of this
invention.
