10 Claims, 3 Drawing Figures PAIENTEDrwzz I972 INVENTOR. RICHARD L. JOHNSON BY ATTnn/vFv LOW-VOLTAGE, ELECTRICALLY HEATED SHIRT PROBLEM AND PRIOR ART In the past the only known heated garments contained electrical heaters which required very high voltages. For this reason such heaters were relatively complex and costly to manufacture. Also the construction of the known garments was such that the heaters were fixedly secured or built into the garment, and consequently the garment could only be worn with the heater attached thereto. Thus the care and cleaning of such heated garments ofiered considerable difficulty.
Also because such known garments could only be energized by relatively high voltage, the movement of a wearer was generally restricted to the length of cord or conductor wire required for carrying the current to the built-in heaters. Because the heaters utilized in the known electrical garments were relatively massive and complex, the garment so heated tended to be bulky and awkward in appearance and use. The limitations thus built in or inherent in the known heated garment types, as a matter of practice, limited them to very restricted application, as for example, for use as a heated flying suit, therapeutic and/or health suits, and the like, in which the mobility, comfort, dress or fashion were not the prime considerations of the garment.
OBJECTS It is an object of this invention to provide a low-voltage, electrically heated shirt having the appearance and comfort of a conventional shirt which can be optionally worn either as a heated shirt or as an unheated shirt.
Another object of this invention is to provide an improved heated shirt construction in which the heater assembly is rendered readily detachably connected to the shirt so that the entire heater assembly may be removed at the will of the wearer in a simple and expedient manner; thereby facilitating the cleaning, laundering and/or care of the garment.
Another object of this invention is to provide an electrically heated shirt in which the location of the heater may be adjustably positioned on the shirt so that the generated heat may be concentrated on a desired portion of the body of a wearer.
Another object of this invention is to provide an electrically heated shirt having a heater construction which can be energized by one or more very low-voltage batteries which may be carried either on the shirt or adjacent thereto.
Another object of this invention is to provide an electrically heated shirt in which the heater assembly is relatively light in weight, and which when attached to the shirt can be concealed from view so that the shirt has the outward appearance of an ordinary conventional type shirt.
Another object of this invention is to provide an electrical shirt construction in which the heater assembly may be drawn close to the body of the wearer when the shirt is worn as a heated shirt so as to provide for a maximum transmission of heat to the body.
Another object of this invention is to provide an electrically heated shirt which is light in weight, and which can be'manufactured in any desired styling.
Another object of this invention is to provide a low-voltage electrically heated shirt which is relatively simple in construction, which can be inexpensively produced, and which is positive in operation.
BRIEF SUMMARY OF THE INVENTION The foregoing objects, and other features and advantages of this invention are attained by a low-voltage, battery energized, heated shirt comprising a shirt of any suitable conventional construction formed with a heater assembly comprising a rela- Wire conductors are electrically connected to the opposed ends of the resistant strip. The other ends of the wire conductors are connected in circuit to a battery source of electrical energy which may be carried in a pouch connected to the shirt or carried by the wearer adjacent the shirt.
The means for detachably securing the heater assembly to the inside surface of the shirt comprises a fastening means connected to the adjacent end portions of the heater assembly, and a plurality of spaced apart sets of complementary fastening means connected to the inside portion of the shirt. The arrangement is such that the fastening means of the heater assembly may be detachably secured to any of the set of complementary fastening means connected to the shirt thereby rendering the heater assembly adjustably and detachably connected to the shirt.

Other features and advantages will become more readily apparent when considered in view of the drawings and specification in which:
FIG. 1 is an expanded view of a shirt construction embodying the present invention.
FIG. 2 is a detail plan of the heater assembly utilized in the shirt construction of FIG. 1, having portions broken away.
FIG. 3 is a sectional view taken along line 3-3 on FIG. 2.
Referring to the drawings there is shown in FIG. 1 a shirt construction 10 embodying the present invention. The shirt 10 may be made in accordance with any well-known construction to define any particular style shirt. Generally, a conventionally constructed shirt includes a back panel 11 and connected side panels 12 which are adapted to enwrap about the body of a wearer. It will be understood that the shirt 10 may be formed with sleeves or without sleeves depending upon the desired styling.
In the illustrated form of the invention the shirt is shown as a typical open front shirt which may be suitably buttoned in the well-known manner when worn. It will also be understood that the shirt 10, if desired, may comprise a pull-over or sweatertype shirt.
In accordance with this invention, an improved low-voltage heater assembly 13 is detachably secured to the shirt 10, as for example, to the back panel portion 11. As best seen in FIG. 2,
the heater assembly comprises an elongated strip of suitable electrical resistant material 14, as for example, Nichrome, or the like. Preferably the Nichrome strip 14 is defined as a long narrow, flat strip of resistant material which is formed into a U-shaped configuration. Because the resistor strip is relatively thin in cross section, e.g., a few thousandths of an inch, 0.002-0.004 inch or the like, and of relatively narrow width, e.g., one-eighth to one-fourth of an inch, the resistant material is sandwiched between a pair of heat diffusing strips of material 15 and 16. It will be understood that the strips of heat diffusing material 15 and 16 may be formed of any suitable material through which the heat generated by the resistant material, when energized, may be conducted or transmitted. For example, the strips of heat diffusing material 15, 16 may comprise of similar or dissimilar strips, for example, acetate tape, fabric tape, metal foil and/or thin plastic tapes which will function to diffuse the heat generated, and to maintain the shape and position of the resistant strip of material 14 sandwiched therebetween.
Preferably, it is desired that the heat diffusing strips 15 and 16 be adhesively backed so that they may be secured in back to back relationship with the strip of electrical resistant material 14, securely bonded therebetween. Connected to, and adjacent the opposed ends of the heater assembly 13, is a fastening means 17 by which the heating assembly 13 may be detachably secured to a panel portion of the shirt, e.g., the back panel 11. As best seen in FIG. 1 a complementary set of fasteners 18, 19 or 20 is suitably secured to the back panel portion of the shirt. In the illustrated form of the invention the heater fasteners 17 and the complementary fasteners 18, 19 or 20 on the panel portion of the shirt may comprise complementary male and female snap-type fasteners of conventional construction. For example, the fasteners 17 on the heater assembly may comprise the male fastener and the set of fasteners 18, 19 or 20 on the shirt the female fasteners.
To render the location of the heater assembly 13 adjustable with respect to the panel portion of the shirt, a plurality of sets of complementary fasteners 18, 19 and 20 are vertically spaced to the panel portion of the shirt. Consequently it will be noted that the heater assembly may be detachably secured to either set of complementary fastening means so that the position of the heater 14 relative to the panel portion of the shirt may be adjusted at the will of the wearerby simply snapping the fastening means 17 of the heater assembly to a corresponding set of complementary fastening means connected to the panel portion of the shirt. The alternate adjusted position of the heater assembly 13 is shown in phantom in H0. ll.
Suitable wire conductors 21, 22 are electrically connected to the opposed ends of the resistant material 14 for conducting the current thereto. The other end of the wire conductors 21, 22 is suitably connected to the contacts or contact plates 21A, 22A carried on a pouch 23 adapted to receive and hold the battery or batteries forming the source of electrical energy for heater 14. If desired, a plug and socket 33 may be disposed intermediate the length of conductors 21, 22.
In the illustrated form of the invention the pouch 23 is constructed so as to snugly receive a dry cell or flashlight type of battery or batteries of conventional construction. In the illustrated form, the pouch 23 is sized to receive two, one and onehalf volttype batteries, or the like, disposed in side by side relationship with the wiring of the contacts adapted to engage the electrodes of the battery within the pouch wired in series, as by a connector conducting wire 25 connecting the lower contact 26 of one battery to the upper contact 27 of the other battery. I
In the illustrated form of the invention the battery pouch 23 is provided with a hook means 28 by which the pouch may be supported on the belt of a wearer, e.g., for the belt supporting the wearers trousers. Altemately the battery pouch 23 may be secured in a pocket formed on the shirt.
The battery pouch 23, may be formed of suitable material to define enclosing walls for snugly receiving the battery or batteries. A flap 23A is provided to secure the battery or batteries within the pouch 23. Preferably the contacts 21A and 27 are carried on the flap portion to engage the electrode of the battery or batteries respectively only when the flap is closed. As shown in FIGS. 2 and 3 a flap closure may comprise an elastic band 30 having a snap fastener 31 by which 'it is detachably connected to a complementary fastener carried by the front wall portion of the pouch 23.
Tie means 29 are connected to the opposed end portions of the heater assembly. In the illustrated form of the invention the tie means comprises a stretchable or elastic band 29-29 connected to each end of the heater assembly to circumscribe the waist portion of a wearer. The free ends of the stretchable bands 29-29 are provided with complementary buckle fastening means 29A, 29B so that the bands may be secured around the waist of the wearer. The arrangement is such that the stretchable bands 2929 when buckled about the waist of the wearer will function to draw the heating assembly 13 close to the body of the wearer so as to facilitate the maximum transfer of heat from the assembly 13, when energized, to the 7 body of the wearer. In this manner the heater assembly 13 is snugly drawn to the body of the wearer, so that maximum utilization of the generated heat is attained.
If desired, a plurality of loops 31 may be provided on the panel portion of the shirt for receiving the stretchable bands 2929.-
With the construction described the arrangement is such that the entire heater assembly 13 can be readily removed from the shirt 10 so that the shirt may be optionally worn either as a conventional shirt, or with the heater 13 in place as a heated shirt. The ease with which the heater assembly 13 is removed from the shirt further greatly facilitates the care and/or cleaning of the shirt as the shirt can be readily sent to the laundry or dry cleaners without the heating element attached. Also the arrangement is such that the heating element can be adjustably positioned with respect to the panel portion of the shirt so that a wearer may locate and/or direct the heat generated by the heater assembly directly to a desired portion of the body. The arrangement is such that a wearer may snugly draw the heater assembly 13 in close proximity to the body so as to effect the maximum transmission of the heat from the heater assembly to the body.
While the present invention has been illustrated and described with respect to a particular embodiment thereof it will be readily appreciated and understood that variations and modifications may be made without departing from the spirit or scope of the invention.
