UNITED STATES PATENT OFFICEA ELECTRICALLY HEATED VEST Felix K. Goudsmit, Larchmont, N. Y.

Application July 8, 1949, Serial No. 103,729

(Gl. 21B-46) 2 Claims. l

This invention relates to new and useful improvements in electrically heated vests.

More particularly, the present invention proposes the construction of a vest having an electrically operated heating pad mounted in the back thereof predominately to be worn by persons engaged in out-oi-door sports activities during cold weather; such as skiers, golfers, skaters, hunters or persons attending out-of-door sports activities such as football games, soccer matches and skating contests, but which is equally adapted to be worn by householders for added warmth or by persons in hospitals or other places for therapeutic and alleviative purposes; such as the treatment of lumbago and other similar back ailments.

Another object of the present invention proposes forming the vest with a front opening and a closely fitting neck opening in a manner to substantially completely enclose the chest area of the body to retain heat from the heating pad.

A still further object of the present invention proposes mounting the heating pad in the back of the Vest between two layers of cloth-like insulation material in a manner to retain the heat for a greater length of time.

The present invention further proposes positioning the heating pad within a pocket formed in the back of the vest which has a bottom opening closed by a fastening means in a manner so that the heating pad can be removed from the pocket permitting the vest to be cleaned independently of the heating pad and to permit'the heating pad to be removed for replacement or adjustment when required.

A further object of the present invention proposes forming the pad of a plurality of heating elements connected in parallel with a thermostatic control for each of the elements in a manner to break the circuit through the heating elements when the internal temperature of the pad reaches 180 F.

Still another object of the present invention proposes providing the pad with a short cord extended to the exterior of the vest and provided with a plug adapted to be connected with an extension cord which in turn is to be connected with a conventional 110 volt electric circuit in a manner to energize the heating pad and bring the internal temperature of the vest up to 189 F. which temperature will be retained for a period of time by the insulation material after which the temperature must be revived by reconnecting the heating pad with the electric circuit.

A further object of the present invention proposes the formation of a vest embodying the principles of the present invention, but designed primarily for use in the home or hospitals for therapeutic treatments.

It is a further object of the present invention to construct a novel vest which is effective for its intended purposes, which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 'l is a front elevational view of Fig. 6.

Fig. 8 is an enlarged Vertical sectional view of the back portion of the vest taken on the line 8--8 of Fig. 6.

Fig. 9 is an enlarged partial elevational view of the inside of one corner of the rear portion of the vest.

Fig. 10 is a rear elevational view of the heating pad, per se, used in the form of the invention shown in Figs. 6 to 9.

The electrically heated vest, according to the first form of the invention shown in Figs. 1 to 5, includes a vest body 20 having a front portion 2| and a rear portion 22. The vest body 20 is formed with a close fitting V-shaped neck opening 23 which is essential in order that the vest body substantially completely enclose the chest portion of the body to retain heat within the vest body. The front portion 2l of the vest body 20 is formed with a front opening 24 which extends from the neck opening 23 downward to the bottom edge of the vest body and which is closed by means of buttons 25. V

On opposite sides of the front opening 24, the

front portion 2l of the vest body is formed with pockets 26 having top openings closed by means of conventional slide fasteners 21.

The front and back portions of the vest body are comprised of an outer layer 28 of cloth, leather or other similar material and an inner lining layer 29. Between the layers 28 and 29 there are two insulation layers 36 formed of wool 0r the like.

Within the center of the back portion .22 of the vest body "26,' lines of vstitches 3| v are engaged through the layers 28, 29 and 36 dividing oif a pocket 32, see Fig. 3, between the insulation layers 38. Positioned within the pocket 32 there is a conventionally constructed heating pad 33.'

The heating pad 33 is composed of an outer cover 34 of water resistant electrical insulation nia--v terial enclosing a plurality of heating elements 35 connected in parallel across a pair of velectric leads 36. The electric leads 36 are extensions of a short length of electric cord 31 provided at its free end with a receptor plug 38. Mounted in eachof the heating elements 35, intermediate the length thereof, there is a thermostat 39 for breaking the circuit through the heating elements Y when the internal Itemperature of the heating pad 33 reaches. 180 F. Further details ofA the construction of the heating pad will not be given as such details, beyond the temperature at which 4the thermostat 39 shuts off the heating pad, form no part of the present invention and are gen,- erally known bythose skilled in the art.

The bottom corner ofl the back portion 22 of the vest body 26 is formed with 'a tunnel 48, see Fig. 4, which terminates in fan opening 4|, between the adjacent vertical edges of the front portion 2| and the back portion 22, through which the free end of the electric cord31 and the receptor plug 38 are extended. Externally of the vest body 20, the receptor plug 38 is adapted to receive the prongs 42, see Fig. l, of a plug 43 mounted on one end of a length of electric cord 44. The other end of the electric cord 44 is formed with a plug 45 which is adapted to be insertedinto the receptacle of a conventional 110 volt electric circuit for supplying the required electrical current to energize the heating pad 33. When the vest is thoroughly heated, the plug 45fis within drawn from the receptacle and the plug 43 is disconnected from the receptor plug 38 and the cord 44 can be rolled up and stored within one of the pockets 26. The insulation layers 36 will act to retain the heat within the vest body 20 fora period of time varying from one-half `to one full hour depending on the outside temperature, after which the heating pad 33 must be reconnected with the source of electric current for re-heating the vest body.

' The back portion 22 is formed along its bottom with an opening 46 closed by means of conventional slide fasteners 41 for removably retaining the heating pad 33 in position within the pocket 32. When the opening 46 is open, it is possible to-remove the heating pad 33 from the pocket 32 permitting the vest body 2|] to be cleanedindependently of the heating pad or permitting the heating pad 33 to be repaired orreplaced, if

necessary. When removing the heating pad 33 from the pocket 32, it is iirst necessary to draw the cord 31 and the receptor plug 38 into the pocket 32 through the opening 4| and the tunnel 46.

In the modified form of the vest shown in Figs. 6 to 10, there is a vest body 56 having a front portion 5| and a back portion 52. The front i portion 5| is separate of the back portion 52 and is in the form of a panel to extend across the back of the wearer. The back portion 52 is shaped to cover the lumbar region of the human back and is comprised of an outer layer 53 and an inner or lining layer 54. The outer layer 53 is formed of leather, cloth or other similar material and the lining layer 54 is preferably of cloth material.

VVinsulation layers 55 vfor.

Between the layers 53 and 54 there is a pair of .ing between them a pocket 56, se Fig. 8, vfor containing a heating pad 51. The top and side edges of the layers 53, 54 and 55 are secured together by lines of .stitches 58, see Fig. 8.

, 59 for4 the pocket 56 closed by slide fasteners forcing piece 15.

' The bottom edges ofthe layers 53, 54 and 55 are freeof each other forming a bottom opening which is arranged to be 66. When the slide fasteners 68 are open, the heating pad 51 can be removed from the pocket 56 through the bottom opening 59.

As in the previous form of the invention, the heating pad`51 is comprised of an outer cover 6| of moisture resistant electric insulation material, which encloses a plurality of heating elements 62, see Fig. l0, connected in parallel across a pair of electric` leads 63 which continue from `the bottom corner of the heating pad 51 as a long electric cord 64. The electric cord 64 iseX- tended from the interior of the pocket 56 through an enlarged hole 65 formed in the lining layer 54 and adjacent insulation layer 55, see Fig. 9. At its free end, the long electric cord 64 is provided with a plug 66, see Fig. 6, which is adapted to be inserted into the receptacle of a conventional volt electric circuit, as described in connection with the iirst form of the invention. Mounted in each of the electric heating elements 62 there is :a thermostat 61, of conventionalconstruction, for breaking the circuit through the heating elements when the internal tempera'- ture of the heating pad reaches F.

A pair of belt members 68 having their rear ends connected to the rear face of the bottom corners of the back portion 52 and have their free ends projected across the front face of the front portion 5|. The free ends of the belt member 68 are projected through loops 69 mounted on the front face of the front portion 5|. The free end of one of the belt members 68 is provided with a buckle 10 having a tongue 1| selectively-engageable with complementary holes formed in the free end of the other belt member 68 for adjustably connecting the belt members 68about the wearers waist. l

A pair of shoulder straps I ends connected to the top portions of the belt members 68 and their front ends attached to the top of the front portion 5|, to extend over the shoulders of the wearer. In order to insure maximum snugness of the back portion 52 against the lumbar region of the back of the wearer, aV pair of straps 14 having their inner ends secured to the top of the back portion 52 beneath a rein- The outer ends of the straps 14 carry clamps 16, of any known design, by which those outer ends are adjustably connected with the shoulder straps 13 intermediate of their ends permitting the attachment of the outer ends of the straps 14 to be adjusted to lit diilerent sized persons.

It is thought that the operation of the form of the invention shown in Figs. 6 to 10 will be apparent when considered in connection with the description of the rst form of the invention and,

13 having their rear therefore, a detailed explanation of the operation of the modified form of the invention is believed to be unnecessary.

W'hile I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as dened in the appended claims.
