DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited to the details of construction and the arrangement of component part set forth in the following description or illustrated by the following drawings. Further, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting but should encompass equivalents thereof.

[0030] Referring now to the drawings and more particularly to FIGS. 1 to 3 there is shown generally at 10 an electrically heated article of warmth, herein a vest 11 adapted to generate heat to a user person’s upper body. The vest 11 has an integrally formed large pocket 12 which is concealed from view to support one or more batteries 13 at desired locations and orientations therein, as shown in phantom lines in FIG. 3, for the comfort of the user person. The pocket 12 is a hollow pocket formed between opposed inner fabric materials 14 and 15, that when placed against one another bind together due to their material compositions to create a retention force which can be separated by pulling the fabrics apart by the use of the wearer person’s hands to create an opening for the placement and orientation of one or more batteries.

[0031] As shown in FIG. 1A, a slit opening 16 is formed in the back panel 17′ of the outer fabric shell 17 of the vest 11 and provided with a zipper fastener 18 for access to the inner hollow space of the pocket 12. A fabric flap 19, matching the outer fabric shell material conceals the zipper fastener 18 from view. Similarly, pockets 12′ may be provided in one or both front panels 17″ of the vest 11 as shown in FIG. 1B, to conceal batteries 13 therein. The slit opening 16 and zipper fastener could also be provided in the inner liner fabric material for access to the pocket and concealed from the outer side of the article of apparel not to intrude on the outer aesthetic appearance of the article of apparel.

[0032] As shown in FIG. 2 the opposed fabric materials 14 and 15 have binding interconnecting microfibers formed in their opposed inner surfaces which when placed against one another exhibit a retention force, much like the connecting fibers of the VELCRO, Registered Trademark, connector materials. However, the microfiber materials utilized in the present pocket construction have opposed surfaces which are smooth and silk-like to the touch, unlike that of VELCRO which is a stiff material. Also, the microfiber fabrics are highly flexible and conform to the shape of the shell and the inner lining of the vest 11. The microfiber material inner surface 14′, of the outer fabric shell 17, is herein constituted by a fiber structure, similar to cotton fibers, and forming loop attachments 14″. The opposite microfiber material of the inner surface 15′ of the inner liner 29 is formed of extra-fine microfibers forming hooks 15″. There are over 1 million such hook microfibers 15″ per sq/inch in the inner surface 15′ and approximately 95,000 loop microfibers 14″ per sq/inch in the cotton-like inner surface 14′ of the outer fabric. It is pointed out that the inner surface 14′ could be formed of the hook microfibers and the inner surface 15′ of loop microfibers which perform the same binding sticky function to retain one or more batteries therebetween. The opposed inner surfaces 14′ and 15′ of the pocket 12 bind together when the pocket is not provided with batteries to maintain the natural draping look of the fabric due to the smooth and flexible nature of the microfibers. As mentioned above, the pocket is opened by unzipping the opening 11 and pulling apart the inner surfaces, as shown in FIG. 2, to release their sticky retention force to create an open space therebetween for the placement of batteries at desired positions.

[0033] As shown in FIGS. 5A and 5B, in order to assure excellent battery retention between the opposed binding microfibers inner surfaces 14′ and 15′, the batteries are provided with a fiber connecting material patch 20 secured to at least a portion of a flat surface 21 thereof. The fiber connecting patch 20 could consist of one of the microfiber materials 14″ or 15″ which is of opposite microfiber material (hook or loop microfibers) to the surface to which it is to be applied against, usually the inner surface 15′ on the liner side of the pocket. To identify the matching fabric for the patch 20, the patch could also be made of a color complimentary to a color of the inner surface of the pocket to which it is to be coupled to. Other code matching means may also be provided to achieve the same result. Also, the patch 20 could cover the entire surface 21 of the battery 13.

[0034] FIG. 5B illustrates the construction of a flexible battery 13′, wherein three battery cells 22 are interconnected together by a flat flexible membrane 23 glued to one side of the three battery cells. The opposite side is herein shown with a microfiber material, preferably but not exclusively the finer hook microfiber material 15″, glued entirely over the surface 21 of the three cells 22 or entirely around the flexible battery opposed surfaces. Such a separated cell battery construction is thinner and flexible and therefore more comfortable to the wearer person by adapting to curved shapes of the wearer person’s body.

[0035] As shown in FIG. 4, two batteries 24 and 24′ are shown electrically connected to one another and held captive between the opposed microfiber surfaces 14″ and 15″ which are interconnected together all around the two batteries by their hook and loop fiber surfaces as well as to the battery patches 20 to retain the batteries in position therebetween, at desired locations and orientations as determined by the wearer person for its comfort adapting to the activity or occupation or body size of the user person or to accommodate the position of articles to be attached or supported exteriorly over the outer surface of the article of apparel. For example, as shown in FIG. 7, the batteries 13 are oriented at positions not to interfere with a backpack 30 and strapping 31 to be supported on the wearer person’s back. Although not shown, the control for the batteries may be mounted at a convenient location on one of the front panels 17″ in a visible mounting or a concealed mounting as described in my co-pending patent application No. 17/581,891, filed on Jan. 22, 2022. The article of apparel herein illustrated is that of a vest, but it is pointed out that such article of warmth may be a jacket, pants, a sleeping bag and other articles of warmth which are electrically heated and for use to warm a wearer person. Also, the pocket may be formed entirely throughout the back panel 17′ or entirely throughout one or both frontal panels 17″, or parts thereof. Although FIGS. 3 and 7 illustrate the batteries 13 oriented in a vertical or horizontal position, these may be positioned at any angular position within the pocket as the positioning is made by inserting the batteries with a person’s hand which may be only partly visible or not visible when in a large pocket. Also, an angular position may be warranted due to the desired comfort of the user person or the adaptability to a sport activity or any other work or pleasure activity of the user person, as mentioned above.

[0036] As illustrated in FIG. 6, the outer fabric shell 17 and the inner liner fabric 29 may be composed of different fabric layers to constitute composite fabric materials. For example, both the outer shell 17 and the inner liner 29 may include a fireproof lining fabric 35 bonded there behind to protect against battery fire. A static shielding fabric layer 36 could also be included in the composite fabric outer shell and liner composite fabric. The outer shell may also be formed of waterproof materials of types well known in the art. The inner fabric liner material sheet 37 may also have a moisture absorbing sheet material also having insulating properties secured there behind. Depending on the intended use of the article or warmth an insulating or cushioning sheet material or a KEVLAR, Registered Trademark, sheet material may be included in the composite outer shell and/or inner fabric liner or any desirable composition of the above. Because there is only one or a few large pockets, this also facilitates the fabrication of the article of warmth. As shown in FIG. 10, small connector cables are installed inside the pocket with sufficient cable length to permit connection(s) to the batteries disposed within the pocket at various desired locations and orientations.

[0037] Referring now to FIGS. 8A and 8B, there is shown a vest 40 in which there is formed a very large concealed pocket 41 constituted by a rear pocket section 42 extending into the back panel 43 and converging into the lower section of the frontal panels 44 to form two frontal pocket sections 45. In order to provide access to the pocket sections 42 and 45, zipper closures 46 may be provided on opposed vertical sides of the rear pocket section 42 to provide access thereto from opposed sides to facilitate the separation of the microfiber inner surfaces which are stuck together and to also facilitate entry into the frontal pocket sections 45. Alternatively, a zipper closure 47 may be provided in the lower edge of the pocket sections to provide access to the hollow pocket sections, particularly so if only one of the opposed inner surfaces has a sticky surface material thereby facilitating easy access to the top section of the rear pocket section.

[0038] FIG. 9A illustrates a pocket construction wherein the opposed fabric materials of the article of warmth is formed with an outer fabric shell 48 provided with an inner surface 48′ formed of hook microfibers. The opposed liner fabric 49 also has an inner surface 49′ formed of loop microfibers. In this embodiment the opposed surface bind together when placed in contact and exhibit a retention force which is separated by pulling apart the outer fabric shell from the inner liner by a force overcoming the binding force of the microfibers.

[0039] FIG. 9B illustrates a pocket construction wherein the opposed fabric materials of the article of warmth is formed with an outer fabric shell 50 provided with an inner sticky surface 50′ formed of sticky microfibers or a sticky rubber coating to receive and retain one or more batteries thereon provided with a sticky patch, as shown in FIGS. 5, and formed of microfibers of different binding fibers than those of the outer shell inner surface 50′ or sticky rubber. The opposed liner fabric 51 has an inner surface 51′ formed of a non-sticky surface whereby not to bind to the inner sticky surface 50′ of the outer fabric shell 50. This construction of the inner surfaces of the concealed pocket facilitates entry and access to the entire concealed pocket(s).

[0040] Referring now to FIG. 10 there is illustrated another embodiment of the present invention, herein a vest 55 in which a large concealed pocket 58 is formed between the rear fabric panel 56 and the inner liner material 57. The concealed pocket 58 is made accessible by a large flap 59 formed in the inner liner material and hinges upwardly for access to the interior of the pocket 58 to expose the inner surface 60 of the rear fabric panel 56, which is herein illustrated provided with loop microfibers 61. The inner surface 62 of the flap 59 is also formed with microfiber material and wherein the microfibers are hook microfibers 63 to bind with the loop microfibers 61 when the flap is in its closed position against the rear fabric panel 56. With this embodiment, the flap 59 is separated from the inner surface 60 of the outer shell and the vest is placed flat on a support surface with the microfiber inner surface 60 exposed to permit the placement of one or more batteries 64 and interconnecting wiring 65 at desired locations and orientations, as herein illustrated. Thereafter, the flap is placed in a closed position over the inner surface 60 and the batteries and pressed thereon about the batteries to retain the batteries 64 captive between the opposed inner surfaces 60 and 62 with the flap maintained in a closed condition. Small VELCRO, registered trademark, patches 66 and 66 may be secured to the inner surface of the flap 59 and the inner surface 60 of the of the rear fabric panel 56 to provide added retainment of the flap 59.

[0041] With the embodiment of FIG. 10, another choice of construction is to provide the batteries with sticky material microfibers in the form of a patch, as shown in FIG. 6, or a sticky coating which will bind to the loop microfibers 61 of the inner surface 60. The inner surface 62 of the large flap 59 of the inner liner would not require binding microfibers therefore providing an easier access to the concealed pocket due to the fact that it would not be required to pull-apart interconnected microfibers between the inner surface 60 of the outer shell and the inner surface 62 of the flap 59. However, to retain the flap in a closed position Velcro patches 66, or small patches of binding microfibers, may be secured at different locations on the inner surfaces 60 and 62. Other form of retention means for the flap may also be contemplated. An advantage of providing access to the pocket from the interior liner of the article of warmth is that the aesthetic of the outer surface of the article is not modified with zipper closures concealed by flaps, etc., for access to the concealed pocket.

[0042] Many other modifications and other embodiments of the present invention as described above will come to mind to a person skilled in the art to which the invention pertains having the benefit of the teachings described herein above and the drawings. Hence, it is to be understood that the embodiments of the present invention are not to be limited to the specific examples thereof as described herein and other embodiments are intended to be included within the scope of the present invention and the appended claims.
