Maintenance and support for warmth in cold weather environments contributes to more comfortable working conditions, enjoyable recreational activities, natural disaster/national disaster emergency relief efforts, and survival in some instances.
Presently available cold weather garments have limited capabilities due to the technology that has been presented as solutions. Clothing available offers warmth by covering the body and relies on the temperature of the body and insulation of the clothing, which in many instances is insufficient for the wearer.
One active solution is battery powered clothing, but this solution has very limited capabilities due to the capacity of power storage, short life of the battery, and costs to maintain. The reliance on battery power that is supplied is impractical for a long term need of warmth. The needed support solely relying on batteries adds to the cost of maintenance due to the recurring need for batteries. High maintenance costs, limited low capacity short life batteries, and the inconvenience of the requirement for the continuous purchasing of additional batteries are all limiting factors. Extending the heating capabilities, the flexibility to support additional charging methods, as well as localization of the heat with minimal maintenance issues, is desirable.
Lighter fluid-fueled hand warmers are available for support of an auxiliary source of heat. There are chemically activated ‘hand warmer’ heat packs which are available and cater to short term certain situations. The use of lighter fluid based hand warmers poses potentially hazardous conditions as a smoldering canister of flammable liquid is introduced into one's garment. Also, chemical heat packs last for limited durations and after initial activation, a boiling point needs to be reached in order to subsequently activate. Due the required method to regenerate the chemical heat packs for further uses, such as boiling water, it is impractical for remote outdoor needs. For cold outdoor weather work and various recreational activities this is not feasible as there is likely no power or no capability to bring the required equipment.
As mentioned above, battery operated garments have limited capabilities and in addition are costly to maintain and inconvenient due to the need for continuous battery replacement and the inability in some cases to acquire replacement batteries in remote areas or in natural disaster situations. Extending the heating capabilities, the flexibility to support additional charging methods, as well as localization of the heat with minimal maintenance issues, is desirable.
The example embodiments to be discussed in detail hereafter provide an environmentally friendly solution by utilizing solar technology and energy storage. In remote areas such inaccessibility to battery products does not lend itself to proper maintaining the warmth required. The present inventor is unaware of cold weather garments that provide each of: (1) environmentally friendly warming solution and energy storage (2) several options for maintaining continuous heat for extended periods of time by utilizing various methods for charging the storage device, (3) temperature control, (4) the ability for outside or ambient temperature information. It would be very beneficial for those wearers involved in cold weather environments to have a garment that exhibits these outlined characteristics that are currently lacking in present cold weather garment solutions.
An example embodiment is directed to a solar-assisted glove. The glove includes a glove body having fingers, a rear surface, front surface and interior space for placing a hand therein, a protective collar for encircling a wearer's wrist at a bottom of the glove body and terminating in a securable release flap on an underside of the wrist below the front surface of the glove body, a solar panel on the rear surface collecting incident solar rays and generating an electrical current in response thereto, a heating element provided in the interior space of the glove body and connected to a printed circuit board (PCB), wherein the heating element is in electrical communication with the solar panel and PCB so that as the solar panel generates electrical current the heating element generates heat within the interior space, and a rechargeable electrical storage means in electrical communication with the solar panel, connected to the PCB and kept on a trickle discharge while storing energy from the solar panel, so as to provide electric current to the heating element. The glove further includes a USB device in electrical communication with the electrical storage means and extending below the glove body front surface for charging the electrical storage means using one or more of a laptop, PC, and AC charger adaptor to an AC mains, and a DC charging adapter plug adjacent the USB device for permitting charging of the electrical storage means via connection to a secondary DC/DC universal adapter that in turn is connected to a DC power source.
Another example embodiment is directed to a solar-assisted garment. The garment includes a garment body having a rear surface panel, front surface panel and interior surface between the panels, a solar panel on the front surface panel collecting incident solar rays and generating an electrical current in response thereto, a heating element provided in the interior surface and in electrical communication with the solar panel so that as the solar panel generates electrical current the heating element generates heat within the interior surface, and a rechargeable battery in electrical communication with the solar panel for storing energy from the solar panel, and to provide electric current to the heating element. The garment further includes a USB device for charging the battery using one or more of a laptop, PC, or AC charger adaptor to an AC mains, and a DC charging adapter plug adjacent the USB device for permitting charging of the battery via connection to a secondary DC/DC universal adapter that in turn is connected to a DC power source.
Example embodiments will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference numerals, which are given by way of illustration only and thus are not limitative of the example embodiments herein.
The glove body 101 includes a protective collar 137 for encircling a wearer's wrist at a bottom of the glove body 101 and terminating in a securable release flap 139 on an underside of the wrist below the front surface of the glove body 101. The rear surface 110 includes a storage compartment 120 (on collar 137) for a rechargeable electrical storage means 125 which is in electrical communication with the solar panel 115 within an interior space of the glove 100 (not shown), such as between layers of material forming the glove body 101. Additionally, the glove 100 includes a flexible heating element 130 provided in the interior space of the glove body 101 (between layers of material forming the glove body 101, not shown for reasons of brevity) and connected to a printed circuit board (PCB) 135 within the collar 137. The heating element 130 is in electrical communication with the solar panel 115, rechargeable electrical storage means 125, and PCB 135 so that as the solar panel 115 generates electrical current the heating element 130 generates heat within the interior space of glove 100. The heating element 130 is flexible and bendable.
The rechargeable electrical storage means 125 is stored within the storage compartment 120 on collar 137. Specifically, the rechargeable electrical storage means 125 is within the collar 137 and located where a back side of a wearer's wrist would be when wearing the glove 100. The electrical storage means 125 is in electrical communication with the solar panel 115, connected to the PCB 135 and kept on a trickle discharge while storing energy from the solar panel 115
This is so as to provide electric current to the heating element 130. In an example, the rechargeable electrical storage means 125 can be configured as a Li-ion or lithium polymer battery, although the example embodiments are not so limited as the rechargeable electrical storage means 125 is contemplated to be any future storage cell, battery or solar storage cell construction, and/or possibly configured as an array of photovoltaic (PV) cells.
The electrical storage means 125 is designed to be recharged from at least two different sources (AC and DC sources). Accordingly, a USB device 140 is provided below the glove body front surface 105 and inside of the release flap 139 for charging the electrical storage means 125, using one or more of a laptop, PC, and AC charger adaptor to plug into an AC mains. In an example, the AC adaptor is an off-the-shelf component that can be purchased from any electronics store, such as an eForCity™ 2-port home wall AC outlet USB charge plug, so that the USB 140 is connected to the AC adapter which in turn is plugged into an AC wall outlet. Further, there is provided a DC charging adapter plug 145 adjacent the USB device 140 for permitting charging of the electrical storage means via connection to a secondary DC/DC universal adapter that in turn is connected to a DC power source. The secondary DC/DC universal adapter is an off-the-shelf component such as a Rhino™ 2500 mA DC/DC car adapter that is configured to receive multiple types of charging plug tips. The DC power source is envisioned as a lighter receptacle or a 12 VDC charging port on a motorcycle or within an automobile.
The rear surface 110 of the glove body 101 includes a temperature sensor 157 arranged thereon, shown just above the solar panel 115. Temperature sensor 157 is in communication with the PCB 125 and can be embodied by a thermocouple, thermistor or metallic RTD, for example. Temperature sensor 157 senses external or ambient temperature and provides a signal to the PCB 125 which in turn displays a reading on an LCD 160 that is positioned on the release flap 139 of collar 137.
There is provided an ON/OFF/SELECT button 150 on the release flap 139 and a set of three LEDs 151, 153, 155. Each LED represents a specific glove internal temperature range that is to be set by actuation of the ON/OFF/SELECT button 150, which functions as a temperature controller as it is in operative communication with the PCB 135 and hence heating element 130, solar panel 115 and electrical storage means 125. LED 151 when lit represents that the glove interior is set at a temperature of 105° F.+/−2 degrees; LED 153 when lit represents that the glove interior is set at a temperature of 110° F.+/−2 degrees; and LED 155 when lit represents that the glove interior is set at a temperature of 115° F.+/−2 degrees.
In operation, a wearer presses the ON/OFF/SELECT button 150 once to turn on the first LED 151, then presses the ON/OFF/SELECT button 150 twice in rapid succession to bring up a menu on LCD 160 that as a default displays the center temperature of the range (105° F.). The wearer can then press the ON/OFF/SELECT button 150 to drop down incrementally in internal glove temperature up to 2 degrees (104° F. or 103° F., displayed on LCD 160), or jump up in temperature (to 106° F. or 107° F.). Once the desired internal temperature is set, the wearer presses the ON/OFF/SELECT button 150 and holds for 2 seconds. If a higher temperature range is desired, the wearer simply presses the ON/OFF/SELECT button 150 to toggle to the next range (LED 153 and/or LED 155), and may (or may not) repeat the process described above to select the desired temperature in that range.
The solar panel 215 on the front surface panel 205 collects incident solar rays and generates an electrical current in response thereto. The heating element 230 is provided in the interior surface and in electrical communication with the solar panel 215 so that as the solar panel 215 generates electrical current, the heating element 230 generates heat within the interior surface or space. The heating element 230 is flexible and bendable. A rechargeable battery 225 is in electrical communication with the solar panel 215 for storing energy from the solar panel 215, and to provide electric current to the heating element 230.

The wrap 200 includes the temperature sensor 257, LCD 260, LEDs 251, 253, 255 and ON/OFF/SELECT button 250 as in the previous embodiment, each arranged on the front surface panel 205. Temperature control of the wrap 200 is effected as previously described above regarding the glove 100, with the exception that it is the internal temperature of the wrap 200 that is adjustable by way of the ON/OFF/SELECT button. Additionally, the side edges may include hook and loop fasteners such as Velcro straps 272, 274. These straps 272, 274 are on opposed side edge surfaces thereof for securing the wrap 200 around a human appendage such as an arm or thigh, for example.
Accordingly, the example embodiments have shown cold weather garments that provide an environmentally friendly warming solution and energy storage, which provides extended use of the garment by utilizing solar and energy storage technologies in conjunction with one another. Additionally, the use of USB device and a DC charging adapter plug provides several options for maintaining continuous heat for extended periods of time by utilizing various methods for charging the electrical storage means. Each garment is provided with temperature control, as well as the ability to discern outside or ambient temperature information on an LCD positioned on the garment.
The example embodiments being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as departure from the example embodiments, and all such modifications as would be obvious to one skilled in the art are intended to be included in the following claims.
