Portable heating device having an illumination apparatus and use thereof
A portable heating device, couplable to a combustible gas, comprising an illumination apparatus for illuminating an environment in which the heating device is positioned. The heating device generally includes a coupling means adapted for coupling the heating device to a source of a combustible gas; and a heating means, responsive to the coupling means, for converting the combustible gas into radiant heat. The illumination apparatus is preferably telescopically adjustable relative to the heating device and is couplable to a source of power, such as electrical energy, at least one battery, a combustible gas, etc., for illuminating the illumination apparatus.
The present invention is directed to a portable heating device. More particularly, the present invention is directed to a portable heating device having an illumination apparatus associated therewith.
BRIEF DISCUSSION OF THE RELATED ARTPortable heating devices, such as those capable of converting a combustible gas, such as liquid propane gas, into a radiant heat, are frequently employed for a plurality of applications. For example, portable heating devices are often used in connection with outdoor recreational activities, such as hunting, camping, etc., and in connection with domestic activities, wherein the device is used to heat a dwelling, such as a home, a cabin, a recreational vehicle, and the like. In general, portable heating devices are used to heat an environment that otherwise is unheated or in need of an auxiliary source of heat. Furthermore, portable heating devices typically couple to a combustible gas as an energy source for generating and radiating heat, and accordingly enjoy increased portability due to the elimination of the need for access to a conventional source of energy.
Portable heating devices, when used in connection with outdoor recreational activities, are often paired with a source of artificial illumination during nighttime activities. For example, campers often position a portable heating device in their tent for providing a source of heat and also position an artificial light, such as a kerosene-powered lantern, therein for providing a source of illumination. Accordingly, this conventional practice increases the burden on campers by requiring them to separately carry both the portable heating device and the source of artificial illumination. Similar complications are encountered in connection with other related activities, such as hunting, the use of a cabin, the use of a recreational vehicle, and the like.
Portable heating devices are also typically used as an emergency back-up measure for providing a source of heat in a situation in which a conventional source of heat is not available, such as during a temporary loss of electricity. Because conventional portable heating devices utilize a combustible gas as an energy source for the generation of heat, they do not require a ready source of electricity and accordingly are operable in emergency situations. Such emergency situations also present complications for illumination considerations, as the lack of electricity renders traditional illumination sources inoperable. Accordingly, individuals typically employ candles, flashlights, and the like to illuminate an area in emergency situations. However, these sources of illumination are often inadequate, as candles provide a limited amount of illumination and flashlights are operable only for a short period of time with a given set of batteries.
BRIEF SUMMARY OF THE INVENTIONIn accordance with one example aspect, the present invention is directed to a portable heating device for generating and radiating heat therefrom. The portable heating device generally includes a coupling means adapted for coupling the heating device to a source of a combustible gas; a heating means, responsive to the coupling means, for converting the combustible gas into radiant heat; and an illumination apparatus, associated with the heating device, for illuminating an environment in which the heating device is positioned.
In connection with another example aspect, the present invention is directed to a portable heating device for generating and radiating heat therefrom. The heating device generally includes a coupling means adapted for coupling the heating device to a source of a combustible gas; a heating means, responsive to the coupling means, for converting the combustible gas into radiant heat; and an illumination apparatus, associated with the heating device, for illuminating an environment in which the heating device is positioned, and wherein the illumination apparatus comprises an illumination means adapted to receive a source of power and convert the received power into radiating illumination.

Additionally, the grill 164 may include a layer of isinglass (not illustrated) associated therewith for protecting heating elements therebehind from disruption generated by wind and/or other gusts of gases. As known, isinglass is generally a layer of mica material that permits the passage of heat radiation therethrough, but otherwise impedes the flow of wind. Accordingly, its association with the grill 154 suitably enables heat to penetrate from the device 100 into its environment and provides a guard against wind interfering with normal operation of the device 100. The isinglass may be associated with the device 100 and/or grill 154 in any desired and appropriate manner, such as, for example, being removably associable with the grill 154 and/or device 100, being securely associated with the grill 154 and/or device 100, and the like.

With reference to an alternate and preferred embodiment, the casing 106 suitably includes one or more apertures 202 for providing access to an inner cavity of the device 100 and the cylinders 200 therein. As best shown in
The portable heating device 100 suitably also includes a means adapted for generating and radiating heat. With reference to a preferred embodiment, the means is provided as a conventional device adapted to receive and convert a combustible gas, such as liquid propane gas, into radiant heat, the construction and components of which are known to one of ordinary skill in the art.
By way of example only and for the sake of illustration, the heating means suitably includes a source of combustible gas and a means for converting the gas into radiant heat. With reference to
The heating device 100 preferably also includes the means for converting the gas into radiant heat. In a preferred exemplary embodiment, the means for converting the gas into radiant heat preferably includes a regulator assembly 172, a gas outlet 174, a venturi 176, a pilot 182 and a heat radiating surface 188, all of which suitably cooperate to convert the gas into radiant heat for heating the environment of the heating device 100. The regulator assembly 172 preferably includes known components for connecting to the proximal and/or remote cylinder(s) 200, accommodating the pressurization of the gas contained therein (i.e., preferably reducing the delivery pressure of the gas from the cylinder), and for transferring the gas to the gas outlet 174. The gas is suitably delivered via the regulator assembly 172 to the gas outlet 174, which then suitably directs the output of the gas into the venturi 176. The venturi 176 is preferably defined by a funnel-like mouth 178 that receives the gas and directs it into a venturi 176 cylindrical body 180. Preferably, the venturi 176 mouth 178 is positioned above the gas outlet 174 and the cylindrical body 180 extends from the mouth 178 upright and, preferably, slightly angularly offset. In general, as the gas is discharged from the gas outlet 174 into the venturi 176, a vacuum-like suction force is created that draws oxygen from the external environment into the venturi 176 through the air inlet vents 156 in the front face 108. Accordingly, the oxygen and gas mix and commingle in the venturi 176 in preparation for combustion. The oxygen and gas mixture travels upward through the venturi 176 cylindrical body 180 and approach the heat radiating surface 188. Once present at the heat radiating surface 188, the oxygen/gas mixture is preferably acted upon by the pilot 182, which is preferably ignited through its igniter 184; however, it is to be appreciated that any conventional means may be employed for igniting the pilot 182. Once the oxygen/gas mixture reaches the heat radiating surface 188 and interacts with the pilot 182, combustion occurs and is maintained as long as a supply of the oxygen/gas mixture is provided to the heat radiating surface. The heat radiating surface 188 is any suitable heat-resistant structure for allowing the radiation of heat outward, such as a burner tile, a multi-ply screen, and the like preferably containing a plurality of apertures that permit combustion of the oxygen/gas mixture as it passes therethrough. As previously mentioned, the heat radiating surface 188 is preferably disposed in the heating device 100 in positional communication with the front face 108 orifice 152 so that the heat generated from the combustion may suitably pass from the heating device 100 into its external environment. Additionally, the heat radiating surface 188 is preferably a rectangular body configured so as to fit in the front face 108 orifice 152.

The thermocouple may optionally be associated with the pilot 182 and be adapted to monitor oxygen levels through observation of the temperature of the pilot flame, changes in which may suitably be indicative of changes in oxygen levels.
According to a preferred embodiment, the portable heating device 100 of the present invention suitably also includes the illumination apparatus 104 associated therewith for illuminating the environment in which the portable heating device 100 is positioned.

In connection with an example embodiment, the illumination apparatus 104 may suitably be provided as a flashlight-like member having an elongate cylindrical body member, a transparent terminal cover, a means adapted for providing illumination, and a source of power for the means adapted for providing illumination. The means adapted for providing illumination is preferably provided as a conventional light bulb, such as an incandescent light bulb, a fluorescent light bulb, a tungsten light bulb, a metal halide bulb, and the like, and is suitably removably associated, for replacement, with the body. The cover is preferably transparent along the entirety of its composition, thereby enabling the light bulb to multidirectionally emanate illumination upward and along a generally three hundred and sixty degree arc of illumination. The source of power is preferably any source of power, such as electric, electrochemical, gas, kerosene and the like. With reference to an example embodiment, the source of power is electric current and the heating device 100 suitably includes a power cord adapted to couple with an electric outlet, such as a wall outlet, and provide the current to the light bulb for powering the same. With reference to another example embodiment, the source of power is one or more batteries. The flashlight-like member is particularly amenable to use with the preferred heating device 100 of the present invention, in that the flashlight may suitably be maintained in a retracted state, according to which the cylindrical body thereof is disposed in the aperture 138, in an extended state, according to which the cylindrical body is supported atop an appropriate structure, such as the projecting member 240, and/or be removably associated with the device 100 and usable as a hand-held illumination apparatus 104.
In connection with yet another example embodiment and
In connection with an example, the heating device 100 and/or one or more components thereof may suitably include a radio associated therewith. In one embodiment, the radio may suitably be associated directly with the illumination apparatus 104, preferably an embodiment in which the illumination apparatus 104 is powered by one or more batteries.

The generator may suitably also be configured so as to deliver electrical power to the illumination apparatus 104.
Despite the foregoing discussion of the illumination apparatus 104, it is to be appreciated that the present invention is not to be limited to the particular shape and structure as depicted in the Figures. Namely, the present invention is generally directed to the concept of a portable heating device 100 having an illumination apparatus associated therewith.
