     FIELD OF THE INVENTION 
     The present invention relates generally to the field of campfire devices and more specifically relates to a device for cooling coals and briquettes below ignition temperature so that the fire has been extinguished fully. 
     BACKGROUND 
     During the last several years, the fire seasons have been particularly destructive, affecting an average of more than four million acres of land in 2013, 2014, and 2015 (or more land than the states of Connecticut and Rhode Island combined.) The fires destroyed many newer homes and communities built on the edges of forest land, and the worst may be yet to come in future years. There is growing concern in the insurance industry because of a recent trend toward increased losses from wildfires and floods. Increased exposure reflects population growth, forcing new development adjacent to wild lands and flood prone areas. These factors, coupled with changes in weather patterns and rainfall, have heightened loss potential. The insured loss from 2015&#39;s fires in California alone was 2 billion. More than seven million homes in California are in areas categorized in the three highest fire-risk levels. Insurers are also exposed to increasing flood losses for commercial and industrial properties. 
     Only a few years ago, several large wildfires in southern California dominated media headlines as they encroached on the suburbs surrounding both San Diego and Los Angeles. In total, about 500,000 acres of land (about the size of Rhode Island) were burned. In addition, a total of 3,581 homes, a countless number of vehicles and a number of commercial buildings were destroyed, disrupting hundreds of thousands of people&#39;s lives. Given this level of destruction, it is apparent that a real need exists for some type of device or apparatus which could be used to safeguard homes and other structures from the risks of being damaged or destroyed by rapidly spreading brush fires or forest fires. 
     Unfortunately, the most prevalent causes of forest fires: inattentive campers and hikers. According to the National Fire Service, over 1,000 forest fires in 2015 were caused by campers. Whether incorrectly preparing an area for a camp fire or thoughtlessly leaving burning embers behind, negligence by campers can lead to the loss of thousands of acres of land, not to mention potential property and life loss. 
     BRIEF SUMMARY OF THE INVENTION 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide picnickers, campers and hikers with a more efficient and effective alternative for ensuring that a campfire has been extinguished fully. 
     The present invention is embodied in apparatus intended to be installed in picnic, camping, and hiking areas where users build fires, e.g. on the ground or in cookers. Alternative embodiments of the invention would be intended to be brought to a longer-term campground by a vehicle. 
     Embodiments of the invention define an inner chamber containing sand and adapted to receive rain water, within an outer chamber punctuated with multiple apertures intended to conduct cooling wind therethrough. A lid at the top is adapted to permit campers to introduce glowing coals into the inner chamber atop the wet sand, where they rest safely until extinguished. Thereafter caretakers of the apparatus may flip open the lid to remove ashes and optionally replace some or all of the sand in the inner chamber. 
     Embodiments of the present invention are preferably fabricated of heavy metal, with an outer casing and an inner container each in the shape of a triangular prism with its axis being vertical. Desirably the vertices of each triangular cross-section are blunted via an additional face, thereby having a cross-section that is irregularly hexagonal. 
     The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description. 
     The present invention holds significant improvements and serves as a device for safely extinguishing hot coals after use in a campfire or grill. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.

     DETAILED DESCRIPTION 
     As conceived, a Stop Fire product in accordance with the present invention would typically be made available in parks for consumer use. Such a device  10  comprises a body unit  12 , having hinged top  14 , base  16 , three sides  18  that are desirably about thirty inches in width, and three sides  20  that are typically four inches in width, wherein body unit  12  has the shape of a triangular prism with its axis vertical, and with vertices blunted by the three sides  20 . A multiplicity of openings  22  are provided in each side  18  of body unit  12  for cooling air flow. In this embodiment, body unit  12  is twenty-five inches in height, and wherein the three four-inch sides  20  and the three thirty-inch sides  12  alternate to form a triangular shape with flat corners, i.e. an irregular hexagon. 
     An inner chamber  24  (see also  FIG. 7 ) is provided within the body unit  12 . Inner chamber  24  contains sand and water as a quenching agent. The water may be provided periodically by caretakers or by exposing the device to rain in the environment. 
     The body unit  12  is made of sturdy metal. The inner chamber  24  body is desirably of aluminum, with some parts being of polymeric substance, to minimize weight of the inner chamber  24 . 
     The hinged top  14  desirably has a magnet  26  on each of its sides to ensure its use in adding hot coals into the inner chamber  24 . It is configured to be openable only by authorized personnel to allow for removal of the inner chamber  24  and emptying it when full. 
     The top  14  has a mesh  28  (see also  FIG. 3 ) with openings of width  60 , for example 3.5 inches, to allow for hot coals to be introduced through the top  14  into the inner chamber  24 . 
     The inner chamber is provided with a part that allows water to flow into its sides and keep the sand therein in a moist state. 
     As shown in  FIG. 2 , the top  14  is prominently labeled “HOT COALS ONLY” where it is visible to users. Being at a height of approximately twenty-five inches, it is a visible warning of the hot contents going into the device. 
     As shown in  FIGS. 6 and 7 , the inner chamber  24  of aluminum has a shape that fits loosely within the body unit  12 . It is desirably twenty-two inches in height and twenty-six inches wide. On each side of the inner chamber  24  are a pair of holes  30  for the entry of rain water. A cool area will be maintained where the temperature of the coal is lowered. The rain water enters the side of the inner chamber  24  that contains sand. As shown in  FIG. 6 , drainage holes  28  are provided in the bottom of the inner chamber  24 . 
     Slots  38  are provided in the inner chamber  24  to facilitate removal from the device for emptying and replacement. 
     The upper section  32  of the inner chamber  24  may be of plastic material that is resistant to heat and yet light weight. 
     The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the Abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
