Cellular telephone support bed for recharge

Abstract

Disclosed is a cellular telephone recharging device which operates as a support bed for a cellular telephone during the recharging stage. The device includes a first pocket for retaining a fire extinguishing packet of super absorbent polymer capable of extinguishing a lithium battery fire. A second pocket is formed within the device for positioning of the cellular telephone over the fire extinguishing packet. Use of the device reduces or eliminates thermal meltdowns by positioning the fire suppressant directly adjacent to the most likely area for the thermal meltdown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(4) Referring now to the figures, set forth is a cellular phone recharging device 10 constructed from a rectangular shaped material forming a base 12 having an upper surface 14 and a lower surface 16. The base 12 includes a first continuous side wall 18 formed along an upper edge 20 of the base 12, forming a first pocket 22. The first pocket 22 is constructed and arranged to receive a packet containing fire extinguishing material as later explained. The base includes a second continuous side wall 40 running along an upper edge of the first continuous side wall 18. The second continuous side wall 40 forms a second pocket 42, which is constructed and arranged to hold a cellular telephone. The second continuous side wall 40 includes a scallop 24 located along an end 26 of the base 12. The scallop 24 is constructed and arranged to allow access to a power plug attachment 102 when a cellular telephone 100 is placed within the second pocket 42. A left side 28 of the second continuous side wall 40 includes a scallop 30 to allow an individual ease of access to the cellular telephone when placed on the base for purposes of removal. Similarly, a right side 32 of the second continuous side wall 40 includes a scallop 34, wherein an individual is able to grasp both sides of the cellular telephone when placed within the second pocket 42.

(5) A fire suppressant packet 50 is sized to fit within the first pocket 22 formed by the first continuous side wall 18 and the upper surface 14 of the base 12. The packet 50 is a sealed pouch for holding about 3 ounces of an admixture 51 of a potassium based super absorbent polymer and water. The packet is constructed and arranged to fit within the first pocket 22 for securement beneath a lid 60. The aqueous admixture of the super absorbent polymer has properties which enable the polymer to be confined to a particular area because of its relatively high viscosity. The properties of the admixture, in particular its viscosity, enable the admixture to remain on vertical, horizontal, and curved surfaces formed by the packet. Unlike pure water, the admixture does not provide an electrically conductive path. The present invention adds a predetermined amount of polymer to a predetermined amount of water to obtain an admixture which has properties that enable the dissipation of heat and suppress the spread of a battery fire. In this embodiment, about one tablespoon of material is employed, as the admixture will be juxtapositioned to the battery. It is to be understood that the ratio of super absorbent polymer to water can vary to produce various physical states of the super absorbent polymer. For example, the viscosity can be adjusted to form a gel, slurry, liquid, semi-liquid, and/or foam. In a preferred embodiment, the ratio of super absorbent polymer to water is adjusted to produce a gel.

(6) The fire suppressant packet 50 is formed from a material selected from the group of low density plastic materials such as polypropylene, polyethylene, polyurethane, polyisoprene, plastics, or combinations thereof. The use of a flexible material is selected for its ability to be flexible and leak resistant, with an ability to hold the hydrated material over a long period of time without evaporation. Polypropylene is a preferred embodiment. The insert packet can be flexible, semi-flexible, or rigid, or combinations thereof.

(7) As used herein, a fire suppressant and fire extinguishing composition is used interchangeably, and is meant to be inclusive of all components of the composition. In some embodiments, the fire extinguishing composition comprises one or more fire suppressant compounds. In other embodiments, the fire extinguishing composition comprises one or more common components of fire suppressant formulations, such as: fire suppressant salts, known or conventional fire suppressants, corrosion inhibitors, spoilage inhibitors, foaming agents, non-foaming agents, flow conditioners, stability additives, thickening agents, pigments, dyes or the like.

(8) Approximately one tablespoon of super absorbent polymer is placed within the packet. The admixture is a biodegradable, super absorbent, aqueous-based cross-linked modified polyacrylamide/potassium acrylate polymer. Other polymers may be used, but not with the same quality level. Examples of these polymers are cross-linked modified polyacrylamides/sodium acrylate, carboxy-methylcellulose, alginic acid, cross-linked starches, and cross-linked polyaminoacids. Preferably, the super absorbent polymer is an admixture of polyacrylamides/potassium acrylate marketed under the trademark FIREICE by the company GelTech Solutions, Inc. In some embodiments, the fire suppressant or fire extinguishing composition is a biodegradable, super absorbent, aqueous-based polymer. The fire extinguishing admixture or fire suppressant may also be any known or conventional fire suppressants. Examples of known fire suppressants include, without limitation, those marketed under the brand name Barricade II, marketed by Barricade International, Thermo Gel 500p marketed by Thermo Industries, AFG Firewall marketed by NoChar, Phos-Chek, AquaGel-K, Focstop-K or Insul-8 marketed by ICL Performance Products, Blaze Tamer 380 marketed by Bio Central Labs, and Tetra KO marketed by Earth Clean Corporation. Other known materials that can be made effective include Purple K potassium bicarbonate, mono ammonium phosphate, sodium bicarbonate, potassium bicarbonate & Urea Complex (AKA Monnex), potassium chloride (Super-K), MET-L-KYL/PYROKYL) variation of sodium bicarbonate, a blended sodium chloride, or a copper extinguishing agent such as that developed by the U.S. Navy for fighting lithium and lithium alloy fires. The copper compound smothers the fire and provides an excellent heat sink for dissipating heat.

(9) A lid 60 is securable to the first continuous side wall 18 to maintain the packet 50 within the first pocket 22. Positioning of the packet behind the cellular telephone is critical if the thermal meltdown is to be immediately neutralized. The lid 60 has an outer edge 62 which fits within a groove 64 formed above the first continuous side wall 18 and along a lower portion of the second continuous side wall 40. The edge 62 of the lid 60 slips within the groove 64 with is preferably formed around the inner surface of the continuous sidewall. The lid 60 secures the packet 50 in the proper position behind the cellular telephone battery area. The lid 60 includes at least one aperture 65 to allow fluid flow from the packet 50, when it is breached, to contact the area of the thermal meltdown. In the event of a thermal meltdown of the lithium battery, the packet 50 is breached by the thermal heat, allowing release of the super absorbent material directly against the cellular telephone. For this reason, a plurality of apertures, as depicted, is desired to allow the super absorbent polymer to contact the area of thermal meltdown as quickly as possible. When the lid is in position, the second pocket 42 forms an area for the placement of a cellular telephone 100. A power cord 102 is illustrated extending through the scallop 24.

(10) The base 12 is constructed from a heat-resistant material, such as plastic or rubber. The base 12 can be shaped to allow the cellular phone 100 to fit snugly within the second pocket 42, wherein the base operates as a non-slip, non-marring support that placed on most any surface during the recharging stage. Additionally the base 12 can be oversized so as to allow different sized phones to be placed in the second pocket 42. It is recognized that the most opportune moment for extinguishing a lithium fire is at the point of creation; thus, the necessity to have an extinguishing material directly contact the thermal breakdown as quickly as possible is critical. The super absorbent polymer also operates to distribute thermal heat during a recharge stage, allowing the cellular telephone to be recharged on heat sensitive objects.
