Foldable campfire extinguisher

Abstract

A novel method for camping with the extinguishment of a campfire comprised of the steps of providing a collapsible campfire extinguisher in compact configuration; traveling to a camp site; utilizing a campfire; deploying the camp fire extinguisher in operable position and placing it over the campfire. A collapsible camp fire extinguisher device comprised of a plurality of panels having registerable holes and a locking means whereby the device transforms from a compact storage position to fanned-out dome position and is operative to extinguish a campfire by starvation of oxygen.

1 . A collapsible dome that transforms from a compact storage position to a fanned-out dome position comprised of: 
 a. a first panel having triangular-like shape, an apex region, first and second edge marginal regions, dome-like curvature, a registerable hole in each of the edge marginal regions and a threaded shank at the apex region that extends approximately perpendicular to the apex region;    b. a plurality of panels each having triangular-like shape, an apex region, first and second edge marginal regions, dome-like curvature, a hole in the apex region, a registerable hole in each of the edge marginal regions which are each rotatably inserted onto the threaded shank via the hole in the apex region;    c. a plurality of washers disposed on the threaded shank with there being a washer between each of the panels and    d. a knob having a threaded internal bore that is rotatably mounted on the threaded shank such that the knob rotates between a loosened position which allows circumferential rotation of the panels about the threaded shank and a tightened position which restrains circumferential rotation,    whereby in the compact storage position, there is a series of stacked panels with the registerable holes in the first edge marginal of all of the panels in the stack being registered alignment and the registerable holes in the second edge marginal region of all of the panels in stack being in registered alignment and    whereby in the fanned-out dome position, there is a series of adjacent panels with the registerable hole in the first edge marginal region of a panel is in register alignment with the registerable hole in the second edge marginal region of an adjacent panel and said edge marginal regions of the adjacent panels have sufficient overlap for the collapsible dome to function as a campfire extinguisher.    
   
   
       2 . A foldable campfire extinguisher kit comprised of: 
 a. The collapsible dome of  claim 1  and    b. a plurality of retainer pins.    
   
   
       3 . A foldable campfire extinguisher comprised of: 
 a. The collapsible dome of  claim 1  in fanned-out dome position where the registerable holes of the edge marginal regions are in registered alignment and    b. a plurality of retainer pins which are inserted into the aligned registerable holes.    
   
   
       4 . A method for safe and convenient camping utilizing a campfire comprised of the steps of: 
 a. providing a collapsible dome in a compact storage position;    b. traveling to a campsite;    c. utilizing a campfire in a firebed;    d. deploying the collapsible dome into fanned-out position;    e. Placing the deployed collapsible dome over the firebed,    whereby, the combustible material in the firebed is starved of oxygen and extinguished.    
   
   
       5 . The method of  claim 5  for safe and convenient camping wherein the collapsible dome is the collapsible dome of  claim 1.
