1. Field of the Invention
This invention relates to a device and method for delivering heat to a predetermined surface, and more particularly, to a device and method having features that increase the heat delivered from the device to a predetermined surface of a human body when falling temperatures require more heat to be generated by the device.
2. Background of the Prior Art
A myriad of prior art devices for warming portions of the human body have been patented. These devices are designed to allow the user of the device to position the heating element portions of the respective device upon an area of the users anatomy exposed to relatively cold temperatures. The problem with prior art devices is that the devices do not provide a relatively quick and inexpensive procedure to increase the heat generated by the prior art heating device to counteract a dropping ambient temperature encountered by the user's body portion requiring a corresponding heat increase.
It is an object of the present invention to overcome many of the disadvantages associated with prior art heating devices for the human body. A principal object of the present invention is to provide a relatively inexpensive body warming device that is capable of being quickly and inexpensively modified to increase the heat output generated by the body warming device. A feature of the device is a pouch having elastic side portions that enable outer and inner surfaces of the pouch to be separated a distance to receive one or more heating elements that generate a quantity of heat required to warm a predetermined body portion exposed to a known ambient temperature. Another feature of the elastic side portions of the pouch is that the side portions cooperate with the pouch and pouch cover to minimize the volume of the pouch to prevent the heating elements from moving inside the pouch when the device is in motion. An advantage of the device is that it allows the quantity of heating elements to quickly and inexpensively increase when temperatures are dropping. Another advantage of the device is that it allows the quantity of heating elements inside the pouch to be quickly and inexpensively decreased when temperatures are rising. Still another advantage of the device is that it minimizes the pouch volume such that the pouch volume is slightly greater than the volume of the heating elements therein, thereby minimizing movement of the heating elements inside the pouch when the device is in motion, resulting in the retention of the heating elements inside the pouch irrespective of pouch movement and/or pouch orientation upon the human body.
Briefly, the invention provides a device for heating a predetermined surface area of a human body including an expandable pouch for heating a predetermined surface area of a human body; at least one heating element for heating the predetermined surface area of the human body to a predetermined temperature; and means for securing the expandable pouch to the predetermined surface area of the human body, whereby, the pouch, with at least one heating element inserted therein, is secured upon the predetermined surface area of the human body to ultimately heat the predetermined surface area to a predetermined temperature.
The invention further provides a method for heating a predetermined surface area of a human body, the method includes the steps of:
providing an expandable pouch for heating a predetermined surface area of a human body;
providing at least one heating element for heating the predetermined surface area of the human body to a predetermined temperature; and
securing the pouch to the predetermined surface area of the human body, whereby, the expandable pouch, with at least one heating element inserted therein, is secured upon the predetermined surface area of the human body to ultimately heat the predetermined surface area to a predetermined temperature.
The invention also provides a heating device that includes a pouch for heating a predetermined surface area, the pouch including a cover;
at least one heating element for heating the predetermined surface area, the at least one heating element being retained inside the pouch irrespective of the orientation of the heating device;
an outer material secured to an outer surface of the pouch and an inner material secured to an inner surface of the cover, such that the cover is ultimately secured to the outer surface of the pouch to maintain the heating element inside the pouch irrespective of the orientation of the heating device, the outer and inner materials adjustably determining the volume of the pouch such that the pouch can removably receive heating elements varying in size and heating capacity, resulting in a pouch volume slightly larger than the volume of the heating elements, thereby minimizing movement of the heating elements relative to the pouch and preventing the heating elements from escaping from the pouch, irrespective of the movement of the device; and
means for securing the pouch to the predetermined surface area, whereby, the pouch, with at least one heating element inserted therein, is secured upon the predetermined surface area to ultimately heat the predetermined surface area to a predetermined temperature.
The objects, advantages and novel features of the present invention, as well as details of an illustrative embodiment thereof, will be more fully understood from the following detailed description and attached drawings, wherein:
Referring now to the figures, and in particular to
The wrist heating device 10 includes a pouch 12 for heating a predetermined surface area of a person's wrist (not depicted); at least one heating element 14 specified to heat the predetermined surface area of the person's wrist to a predetermined temperature; and a band or strap 16 for securing the pouch 12 to the predetermined surface area of the person's wrist, whereby, the pouch 12 having at least one heating element 14 inserted therein is secured upon the predetermined surface area of the person's wrist to ultimately heat the predetermined surface area to a predetermined temperature. Although one heating element 14 is generally sufficient to comfortably heat a person's wrist, in relatively cold temperatures, the pouch 12 is sized and configured to expand to receive two or more heating elements to generate sufficient heat to maintain a comfortable temperature upon the person's wrist.
The pouch 12 can be manufactured from a myriad of materials that are flexible and that conduct heat, including but not limited to sweat absorbing material such as that used for wristbands, a flannel material, polyesters, a relatively thin, durable animal hide material such as suede, and an elastic material. The pouch 12 includes a substantially rectangular or square configuration having dimensions that correspond to a range of wrist sizes. Generally, four different pouches 12 are configured and dimensioned to correspond to four different wrist sizes characterized as small, medium, large and extra large.
The heating element 14 includes a myriad of heating elements 14 that are commercially available and that insert into the pouch 12. A preferred heating element 14 is manufactured by HeatMax Inc. in Dalton, Ga. 30722. The HeatMax heating element 14 manufactured under the brand name of “Hothands” and identified as item HH2. The Hothands heating element 14 is foldable to promote the insertion into the pouch 12 without damaging the heating element 14 or interfering with the heating parameters of the heating element 14, thereby allowing one or more of the Hothands heating element 14 into the pouch to effectively heat a person's wrist area, irrespective of ambient temperatures.
The pouch 12 includes a cover 18 for retaining the heating element 14 inside the pouch 12, irrespective of the orientation of the heating device 10. The cover 18 is maintained in a closed position by a relatively small portion of a hook or outer material 20 detachably receiving a relatively small portion of a loop or inner material 22. The hook and loop material 20 and 22 is well known to those of ordinary skill as being manufactured pursuant to the trademark “Velcro.” The loop material 22 is secured to an inner surface 24 of the cover 12 via thread 23, staples or similar securing elements, and is ultimately urged to engage the hook material 20, which is secured to an outer surface 26 of the pouch 12, thereby securing the cover 18 to the outer surface 26 of the pouch 12 to maintain the heating element 14 inside the pouch 12, irrespective of the orientation or motion of the heating device 10. The portions of hook and loop material 20 and 22 are dimensioned to allow the cover 18 to be secured to the pouch 12 at multiple positions to promote the expansion or contraction of the volume of the pouch 12 to correspond to the volume of the quantity and dimensions of heating elements 14 ultimately disposed in the pouch 12. The feature of providing a means for varying the attached position of the cover 18 upon the pouch 12 enables the user of the device 10 to maintain the volume of the pouch 12 slightly larger than the volume of the heating elements 14, thereby minimizing movement of the heating elements 14 relative to the pouch 12 and preventing the heating elements 14 from escaping from the pouch 12, irrespective of the movement and orientation of the person wearing the device 10.
The cover 18 is manufactured from the same flexible material as the pouch 12. The cover 18 is dimensioned to cooperate with the portions of hook and loop material 20 and 22 dimensions to allow the cover 18 to be secured to the pouch 12 when the heating element 14 is dimensioned such that the heating element 14 extends beyond a top edge 28 of the outer surface 26 of the pouch 12. The cooperation between the pouch 12, cover 18, and portions of hook and loop materials 20 and 22, enable the pouch 12 and cover 18 to removably receive one of a range of heating elements 14 varying in size and heating capacity; 2.) removably receive multiple heating elements 14; and 3.) removably receive multiple heating elements 14 varying in size and heating capacity to heat a person's hand and/or wrist portion via an inner surface 34 of the pouch 12 engaging a predetermined portion of the person's wrist and/or hand.
The band or strap 16 is fabricated from a stretchable, elastic material and is secured to opposite side portions 30 of the pouch 12 via thread stitching 31, such that a wrist receiving aperture 32 is formed to allow a person's hand to insert between an inner surface 34 of the pouch 12 and an inner surface 36 of the strap 16, until the pouch 12 and strap 16 is snugly secured to the person's wrist, thereby maintaining the pouch 12 with a heating element 14 secured therein by the cover 18 upon a predetermined surface area of the person's wrist to provide sufficient heat to the person's wrist and hand, irrespective of the ambient temperature surrounding the person.
The side portions 30 are fabricated from an elastic or stretchable material well known to those of ordinary skill in the art. The side portions 30 in an “un-stretched” position separate the outer and inner surfaces 26 and 34 substantially about one-half inch, but shorter or greater distances of separation can be specified to cooperate with a selected heating element 14 to be inserted into the pouch 12 that has a relatively “thin” or “thick” dimension. Further, the side portions 30 in a “stretched” position separate the outer and inner surfaces 26 and 34 substantially about one inch to allow the pouch 12 to receive multiple heating elements 14 arranged similarly to a deck of cards when inserted into the pouch 12. The one inch distance of separation can be shorter or greater depending on the number of heating elements 14 that will be ultimately inserted into the pouch 12 to achieve a predetermined heating quantity for the person's wrists when exposed to relatively cold temperatures. The hook and loop materials 20 and 22 are dimensioned to secure the cover 18 upon the pouch 12 irrespective of the distance separating the outer and inner surfaces 26 and 34 of the pouch 12.
