BACKGROUND OF THE INVENTION
This invention relates generally to a body cooling device and more
particularly to a scarf, wrap or collar which may be worn about the neck
of a person subject to high ambient heat conditions.
This scarf, wrap or collar may comprise an envelope of a porous fabric
material capable of being shaped to conform to and hold itself against the
contour of a body area being covered. The envelope is intended to contain
ice, the melting of which will penetrate the fabric material and cool the
surrounding body area while one is engaged in work, sports or other
vigorous activities in a hot environment.
In some instances, the envelope may be lined with a liquid impervious
material and in this instance, the wrap will transfer a dry cool
temperature to the body of the wearer.
DESCRIPTION OF THE PRIOR ART
Although the beneficial effects of the application of wet and dry cold
compresses to the body in hot weather have long been recognized, the uses
of such compresses have generally been applied to patients lying in a bed
or otherwise inactive. Those that have been designed for persons active in
a vigorous activity, have not been designed for effective use.
U.S. Pat. No. 4,641,655 discloses a therapeutic cooling wrap designed for
tying around the neck of a person. A bag closed by a zipper forms a pouch
in a strip of pervious fabric. The strip of fabric is further stitched to
form tying straps on both ends of the pouch. A pad of open-pored foam is
secured in the bag to insulate the neck from severe cold still permitting
the controlled dispensing of water to the neck area.
U.S. Pat. No. 4,356,709 discloses an ice cap having an inner wall and an
outer wall defining a sealed cavity. The inner wall is comprised of an
inner laminate of moisture impervious material and an outer laminate of
textile material such as cloth. The outer wall is essentially the same.
U.S. Pat. No. 3,889,684 discloses a hot and cold pack which may be secured
to the neck by a VELCRO-type fastener.
U.S. Pat. No. 3,678,936 discloses an ice bag comprising two sleeves of
rubberized flannel disposed one within the other and sealed. When the
zipper is opened, ice is inserted therein.
U.S. Pat. No. 4,576,169 discloses a collar to be worn around the neck for
cooling. A towel member encloses an insulating member with a cooling
pocket located between the insulating member and the user's neck.
U.S. Pat. Nos. 1,567,931 and 1,616,961 disclose compresses and neck bags
containing ice or liquid which are of a different geometrical
configuration than that disclosed herein.
Canadian Pat. No. 718,686 discloses an envelope which conforms to fit
around the entire neck of a user which contains a particular filling
possessing the quality of retaining heat over relatively long periods of
time.
None of these patents disclose the structure claimed which is simple in
design, effective in use and can be easily used by man, woman or child
when out of doors in a hot environment.
SUMMARY OF THE INVENTION
In accordance with the invention claimed, a new and improved wrap around
scarf or collar is disclosed which is economical to manufacture and
effective when used to aid in rendering activities in a hot environment
more feasible.
It is, therefore, one object of this invention to provide a new and
improved elongated device such as a scarf, wrap or collar which can be
comfortably worn about the neck of a person subjected to high ambient heat
conditions to effectively and efficiently lower the body temperature of
the wearer.
Another object of this invention is to provide a cooling scarf, wrap or
collar that can receive and retain a frozen water medium and which
dispenses water as the frozen water medium melts through a porous medium
to the skin of the wearer.
A further object of this invention is to provide a cooling scarf, wrap or
collar that receives a frozen water medium within a liquid nonpervious
envelope to which body heat can be transferred.
A still further object of this invention is to provide a new and improved
wrap around scarf that can be secured to the body of the user while one is
engaged in sports or other vigorous activities.
A still further object of this invention is to provide a wrap around scarf
which can be economically manufactured and sold at a reasonable price.
Further objects and advantages of the invention will become apparent as the
following description proceeds and the features of novelty which
characterize the invention will be pointed out with particularity in the
claims annexed to and forming a part of this specification.
BRIEF DESCRIPTION OF THE DRAWING
The present invention may be more readily described by reference to the
accompanying drawing in which:
FIG. 1 illustrates the upper half of a user with a cooling scarf embodying
the invention wrapped around his neck;
FIG. 2 is an elongated view of the scarf shown in FIG. 1;
FIG. 3 is a cross-sectional view of FIG. 2 taken along the line 3--3;
FIG. 4 is a cross-sectional view of a modification of the scarf shown in
FIGS. 1-3; and
FIG. 5 is a perspective view partly broken away of a frozen medium
enclosing insert for insertion in the hollow cavity of the structure shown
in FIGS. 1-3.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring more particularly to the drawing by characters of reference,
FIGS. 1-3 disclose an elongated cooling ice applicator, scarf, wrap or
collar 10 for tying around the neck of a wearer 11. This scarf, as shown
in FIG. 2, comprises an elongated hollow cylindrical-like member formed of
an absorbent textile material, the interior of which forms an envelope 12,
the cavity of which may be filled directly with ice or with one or more
containers filled with a freezable medium.
Although the scarf or cooling wrap may be used as a cold compress for
application to another part of the body, it is especially intended to be
worn, as shown in FIG. 1, around the neck when the user is engaged in
vigorous activity such as playing tennis, performing physical labor or
exercising and the like. The removal of heat from the neck area, as is
well known, will give relief from some of the symptoms associated with
being overheated. Heat is removed from the neck area by scarf, wrap or
collar 10 by conduction and/or the dispensing by it of a controlled amount
of water on the neck which absorbs the heat through evaporation.
As noted from FIG. 2, the configuration of cooling scarf, wrap or collar 10
comprises an elongated single strip of fabric such as an absorbent
toweling material which is folded back on itself and stitched in an
overlapping manner to form a hollow interior 13 which is opened and closed
by zipper means 14 which is covered by an overlapping edge 15 of the
material. Zipper means 14 is shown as extending along only a part of the
length of scarf 10 midway of its length.
The fabric strip used to form the cooling wrap may be approximately 36
inches long, 9 inches wide and when folded over on itself from end to end
and stitched, forms an envelope with a 7 inch circumference with a flap or
overlapping edge 15 of approximately 2 inches covering the zipper means
14.
As shown in FIGS. 2 and 3, the interior of envelope 12 is lined with a
liquid impervious material 16 to form a lining or bag for the scarf or it
may be periodically supplied with one or more containers containing a
freezable medium 17 as hereinafter described, which may be repeatedly used
and refrozen.
Since the scarf is formed of a toweling material 18, the use of the scarf
shown in FIGS. 1-3 will cool the user by conduction.
FIG. 4 illustrates a modification of the scarf shown in FIGS. 1-3 wherein
the scarf is formed as shown and described for FIGS. 1-3, but differs
therefrom by omitting the lining shown therein. In this illustration, the
toweling material 18 will become saturated by melting ice, i.e. ice cubes
or crushed ice, forming the freezable medium 17 placed in envelope 11. As
the ice cubes melt, the water released is immediately transferred to the
toweling material 18 of the cooling scarf, and then to the neck area of
the user. This water is gradually released as evaporation occurs from the
cooling scarf and the neck and chest area of the wearer.
Once the frozen water medium is placed in envelope 12 of the scarf whether
or not it contains a liquid nonimpervious lining and the envelope is
closed by zipper means 14 and placed around the neck of a wearer, as shown
in FIG. 1, the opposite ends 19 and 20 of the scarf are brought together
and held in a juxtapositioned side-by-side arrangement by a fastening
means 21.
This fastening means comprises a strap 22 with the ends of the strap each
being provided with one portion 23 of a VELCRO (hook and loop) fastener
member and the corresponding area of the other end of the strap being
provided with a cooperating VELCRO member 24.
This fastening means is provided for easy clamping together of the ends of
the scarf around the neck of the wearer and removable therefrom.
A further fastening means 25 is provided for securing the scarf around the
chest of the wearer so as to prevent the scarf from flopping around when
used by one involved in a vigorous activity such as running.
This fastening means comprises a pair of clamps 26 and 27, one fastened on
each of the opposite ends of the scarf and on a common side thereof as
shown in FIG. 2. A strap 28 with suitable adjustment means for varying the
end of the strap is provided for engaging clamps 26 and 27 to hold the
ends of the scarf against the chest of the wearer in a known manner.
FIG. 5 discloses one form of a container 29 which may be used for insertion
into envelope 12 to form the freezable medium 17.
In this instance, container 29 comprises a plurality of interconnected but
separated pouches 30A-30I, each formed with a liquid nonpervious surface
which are interconnected in the sequential arrangement shown by a necked
down web 31 between each of the pouches. These webs each form a hinge
permitting container 29 to form a straight line or arcuate configuration
depending on the configuration of the scarf when in use or stored.
This container may be repeatably used after each freezing cycle.
Although but a few embodiments of the invention have been shown and
described, it will be apparent to those skilled in the art that various
changes and modifications may be made therein without departing from the
spirit of the invention or from the scope of the appended claims.
