Description
BACKGROUND OF THE INVENTION
The present invention relates to a carrier for a portable heater,
for use as a hand warmer out of doors by spectators, sportsmen and
the like.
It has long been known to be desirable to provide protective
clothing for people engaged in such out-door pursuits as hunting,
fishing, skiing, etc., as well as out-door spectator sports. For
the hands, in particular, mitts and gloves have been provided, but
in situations where there was long exposure to cold, where the
temperature was unusually low, and/or a strong wind was blowing,
these protective clothing devices were not found to be
satisfactory, since they had no source of heat incorporated in
them. Consequently, there were later developed various articles of
clothing which had an energy source.
One typical type of clothing including an energy source was the
glove, sock or the like which was heated by the incorporation
therein of small conductive wires or similar elements, with energy
supplied from a small battery. While these gloves and socks
generally proved to be satisfactory as long as the battery was
operative, it frequently happened that the battery became
inoperative at inopportune times, and spare batteries were not
available. Also, it is known that some batteries are prone to
having their lives shortened, or their energy level lowered, by
exposure to cold. Hence, the battery operated clothing has not
provided a completely satisfactory solution.
Other types of heating devices for these areas of use include hand
warmers in the nature of small portable and hand-size heaters
having as their source of energy some combustible fuel. The most
prominent fuels have been liquid fuels, and in some instances,
solid fuel has been used. In a known portable heater, a solid fuel
element in the shape of a briquette or an elongate stick was
provided, for ignition by a match or lighter, and the briquette or
stick was carried in a suitable casing which was of some
incombustible material, but which was supplied with openings or
apertures to permit the circulation of air therethrough, so as to
supply the necessary oxygen to the solid fuel element therein.
SUMMARY OF THE INVENTION
The present invention provides a carrier for a portable heater of
the type comprising a solid combustible fuel element supported in
an incombustible casing, which is substantially hand-size. This
carrier is in the form of a bag having an opening at the top
thereof, which is closed by a suitable closure, such as a zipper.
The portable heater is placed in the bag and the zipper closed. In
addition, a flap is secured to an outer wall of the bag, the flap
having a generally rectangular shape and secured along its top and
bottom edges to the outer wall, as by stitching. At the sides of
the flap, a pair of wrist protectors are secured, the wrist
protectors being in the form of sleeves having elastic bands at
their outer ends to provide cuff-like arrangements. Thus the hands
of a sportsman may be inserted through the sleeves, and occupy the
warming space provided between the outer wall of the bag and the
flap. In addition, a slot may be provided in the outer wall,
underlying the flap, so that the hands of the wearer may be
inserted through the slot, into direct contact with the portable
heater. A shoulder strap is preferably provided so that the bag of
the carrier may be slung over the shoulder of the wearer, or around
his neck. The material of the bag and flap is air permeable, so
that air may pass through and support the combustion of the solid
fuel in the heater: preferably an inner layer of wool-felt and an
outer nylon fabric cover are used as the material for the bag and
flap.
Among the objects of the present invention are to provide a carrier
for holding a heater of the solid fuel and casing type, and to
provide such a carrier which will both retain the heat of the
portable heater, and permit air to pass to the solid fuel thereof.
Another object of the present invention is the provision of a
carrier having provision for hand access to the heater. A still
further object of the present invention is to provide a carrier
which will avoid loss of the heater, and at the same time provide a
place sheltered from the wind and the elements where the hands of a
person may be warmed without undue loss of heat therefrom. Other
objects and many of the attendant advantages of the present
invention will be more readily understood from the following
specification and drawings.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 is a perspective view of a portable heater of a known
type.
FIG. 2 is a perspective view, with parts broken away, of a carrier
in accordance with the present invention.
FIG. 3 is a cross sectional view taken on the line 3 - 3 of FIG.
2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, wherein like or corresponding
reference numerals are used to designate like or corresponding
parts throughout the several views, there is shown in FIG. 1 a
portable heater generally designated 10 which includes a casing
bottom 12 having a recess 14 therein for supporting a solid fuel
element 16. Hingedly connected to one edge of the bottom 12 is a
casing top 18, which may also be provided with a suitable recess
20. The casing parts 12 and 18 are of a suitable incombustible
material, and may include openings 22 or the like for permitting
combustion-supporting air to reach the solid fuel element 16. A
suitable closure element is provided so as to hold the casing parts
12 and 18 in closed position. As will be understood, the solid fuel
element 16 may be ignited by a match, lighter, or the like, and
then the heater may be closed and held in the closed position,
combustion or burning of the fuel element 16 continuing for as long
as 12 hours, depending upon the size of the fuel element 16.
In order to provide a suitable carrier for the heater 10, to avoid
loss, and the like, there is provided a carrier 30, as shown in
FIGS. 2 and 3, carrier 30 comprising a bag 32 having walls 34 and
36 forming its sides, end walls 38 and 40, and the bottom 42. An
opening is provided at the top of the bag 32, closed by a suitable
closure such as the zipper 44. A suitable strap 46 has its ends
attached to the bag 32 adjacent the top thereof. Within the walls
and bottom of the bag 32 there is provided a compartment for the
heater 10, which is shown within the compartment, in dashed
lines.
Secured to the outer wall 36 of the bag 32 is a flap 50, flap 50
being secured adjacent its top margin 52 and bottom margin 54 by
means such as conventional stitching. The flap 50 is generally
rectangular, and the vertical margins 56 and 58 thereof are not
secured to the wall 36 of bag 32, but instead preferably have wrist
protectors 60 secured thereto. Wrist protector 60 is generally in
the form of a sleeve having its inner end stitched to the edge 56
of flap 50, and also stitched to the outer wall 36 of the bag 32. A
constriction of the outer end of sleeve 60 is provided by an
elastic band, not shown, which provides the shirring 62, in the
form of a cuff. It will be understood that there is a wrist
protector 60 at each end of the flap 50, and the wrist protector 60
at the right hand end of FIG. 2 will be understood to have been
tucked between the flap 50 and the outer wall 36 of bag 32.
There is provided in the wall 36, near the middle thereof, a
generally vertically extending slot 70, which will permit entry of
the hands of the user, or at least the fingers of a user, into the
compartment holding the heater 10, so as to enable the fingers or
hand to come into direct contact with the heater 10.
The flap 50 is made of multiple layers including a middle layer 64
of polyester urethane, intermediate layers 66 of glass wool, and
outer layers 68 of woven nylon. Thus the flap 50 has great
insulative value, permits passage of a small quantity of air, while
being substantially wind and water proof.
Referring now to FIG. 3, there may be seen the heater 10 within the
compartment of the bag 32 of carrier 30, lying on the bottom wall
42, and between the outer walls 34 and 36. There may also be seen
the flap 50 with the upper edge 52 and lower edge 54 secured to the
outer wall 36. The wrist protector 60 is indicated between the flap
50 and wall 36.
As will be seen from FIG. 3 in particular, the bag 32 is made of a
suitable material comprising an inner layer 72, which is of air
pervious wool-felt, the felt layer 72 being covered by a nylon
fabric cover material 74, which is woven so as to permit the
passage of some air therethrough, sufficient to support combustion,
and which is also substantially water-proof.
In use, the fuel element 16 is lighted as above noted, and the
portable heater is then placed within the compartment of the bag 32
of carrier 30. The zipper is then closed, and the bag 32 may be
supported by the strap 46 extending about the neck of the user. The
user's hands may then be inserted through the wrist protectors 60,
where the elastic band therein will prevent the entry of cold air,
particularly when the wind is blowing. If it is necessary or
desirable to have the fingers and/or entire hand of the user warmed
more quickly, use may be made of the slot 70 in the wall 36 so as
to establish direct contact between the hand and the heater 10. The
material of the bag will be seen to be heat insulative, keeping the
heat within the bag, and within the compartment defined by the flap
50, while at the same time permitting combustion to continue by
permitting a small but sufficient amount of air to pass through the
material from which the bag 32 is made.
There has been provided a carrier for a portable heater of the type
containing solid fuel, which will prevent the loss of the heater,
while providing ready access for the hands of the user, the carrier
herein being readily transported by a person by carrying it by a
suitable strap over his shoulders. The present invention carrier
will be seen to protect the hands against the elements by a
relatively wind-proof compartment, and also provides direct access
for the hands to the heater. The present invention heater carrier
also provides suitable combustion air to the heater, while
preventing water, such as rain, from reaching the fuel element of
the heater.
It will be obvious to those skilled in the art that various changes
may be made without departing from the spirit of the invention, and
therefore the invention is not limited to what is shown in the
drawings and described in the specification but only as indicated
in the appended claims.
