Target device

Abstract

A target device is disclosed. The target device includes a back board; a front board attachable to the back board; one or more initiators attachable to the back board at a back surface of the one or more initiators; one or more pyrotechnic compositions contactable with the one or more initiators at a top surface of the one or more initiators, the one or more pyrotechnic compositions retainable between the front board and the back board when the front board and the back board are attached.

         2 . The target device of  claim 1 , wherein the one or more pyrotechnic compositions comprises copper oxide thermite, black powder, smokeless powder, flash powder, or any combination of same. 
     
     
         3 . The target device of  claim 1 , wherein the one or more initiators is Armstrong's mixture. 
     
     
         4 . The target device of  claim 1 , further comprising one or more effect compositions, a back surface of the one or more effect compositions contactable with the one or more pyrotechnic compositions at a top surface of the one or more pyrotechnic compositions. 
     
     
         5 . The target device of  claim 4 , further comprising a puncturable material between the back surface of the one or more effect compositions and the top surface of the one or more pyrotechnic compositions. 
     
     
         6 . The target device of  claim 5 , wherein the puncturable material is tissue paper. 
     
     
         7 . The target device of  claim 1 , further comprising a wrapping surrounding an outer surface of the front board and an outer surface of the back board. 
     
     
         8 . The target device of  claim 7 , wherein the wrapping comprises tissue paper. 
     
     
         9 . The target device of  claim 1 , further comprising a targeting indicator at an outer surface of the front board. 
     
     
         10 . The target device of  claim 1 , further comprising a tab attachable to the target device and configurable to support attachment of the target device to an object. 
     
     
         11 . The target device of  claim 1 , wherein the back board comprises an about 1.5 mm thick poster board, the front board comprises an about 1 mm thick poster board, and the target device is about ⅝ inches thick measured from a back surface of the back board to a front surface of the front board. 
     
     
         12 . The target device of  claim 1 , wherein the front board is attachable to the back board to form an enclosure retaining the one or more pyrotechnic compositions. 
     
     
         13 . The target device of  claim 1 , further comprising a puncturable material between the back surface of the one or more pyrotechnic compositions and the top surface of the one or more initiators. 
     
     
         14 . The target device of  claim 13 , wherein the puncturable material is tissue paper. 
     
     
         15 . The target device of  claim 4 , wherein the one or more effect compositions comprises smoke dye powder, strontium nitrate, barium nitrate, iron oxide thermite, copper oxide thermite, magnesium, a crackling effect mixture, or any combination of same. 
     
     
         16 . The target device of  claim 4 , wherein the one or more effect compositions comprises a smoke dye powder having about 34% smoke dye, about 30% potassium chlorate, about 18% lactose, about 16% magnesium carbonate, and about 2% sodium bicarbonate. 
     
     
         17 . The target device of  claim 4 , wherein the one or more effect compositions comprises a crackling effect mixture having about 65-75% bismuth trioxide, about 10-15% copper oxide, about 5-15% magnalium and about 5-15% aluminum. 
     
     
         18 . The target device of  claim 4 , wherein the one or more effect compositions comprises a layer of paraffin wax pellets covered with copper oxide powder. 
     
     
         19 . The target device of  claim 1 , wherein the one or more initiators comprises:
 KClO 3  in the range from about 45% to about 50%;   antimony sulfide in the range from about 28% to about 33%;   accroides resin in the range from about 3% to about 5%; and   sulfur in the range from about 12% to about 24%.   
     
     
         20 . A method for exploding in target shooting, comprising:
 providing a thin separation between one or more initiators and one or more pyrotechnic compositions;   igniting one or more initiators and one or more pyrotechnic compositions following application of a force; and   exploding the one or more pyrotechnic compositions to produce an effect following the igniting.
