Avalanche triggering system

Abstract

An explosion chamber for an avalanche triggering system including a lower half-chamber closed at its lower end and having an opening at its upper end, and an upper half-chamber closed at its upper end and having an opening at its lower end. The lower end of the upper half-chamber extends around the upper end of the lower half-chamber, or the upper end of the lower half-chamber extends around the lower end of the upper half-chamber, so as to create at least one gas flow channel. The gas flow channel includes a baffle formed by the lower end of the upper half-chamber and the upper end of the lower half-chamber.

1 . An explosion chamber for an avalanche triggering system, the explosion chamber comprising:
 a lower half-chamber closed at its lower end and comprising an opening at an upper end,   an upper half-chamber extending above the lower half-chamber, closed at an upper end and comprising an opening at a lower end,   characterized in that the lower end of the upper half-chamber extends around the upper end of the lower half-chamber, or the upper end of the lower half-chamber extends around the lower end of the upper half-chamber, so as to create at least one gas flow channel between an inside and an outside of the explosion chamber, the gas flow channel comprising at least one baffle formed by the lower end of the upper half-chamber and the upper end of the lower half-chamber.   
     
     
         2 . The explosion chamber according to  claim 1 , wherein the lower half-chamber and the upper half-chamber are attached to one another by resiliently deformable means. 
     
     
         3 . The explosion chamber according to  claim 1 , wherein the gas flow channel extends around an entire periphery of the explosion chamber. 
     
     
         4 . The explosion chamber according to  claim 1 , wherein the gas flow channel extends over part of a periphery of the explosion chamber. 
     
     
         5 . The explosion chamber according to  claim 2 , wherein the gas flow channel extends over part of a periphery of the explosion chamber. 
     
     
         6 . The explosion chamber according to  claim 1 , comprising several distinct gas flow channels extending around an entire periphery of the explosion chamber. 
     
     
         7 . The explosion chamber according to  claim 2 , comprising several distinct gas flow channels extending around an entire periphery of the explosion chamber. 
     
     
         8 . The explosion chamber according to  claim 1 , wherein the upper half-chamber comprises at least one internal chimney or partition extending inside the upper half-chamber. 
     
     
         9 . The explosion chamber according to  claim 1 , wherein the lower half-chamber comprises at least one internal chimney or partition extending into the lower half-chamber. 
     
     
         10 . An assembly formed by the explosion chamber according to  claim 1  and a support for the explosion chamber. 
     
     
         11 . The assembly according to  claim 10 , wherein the support and the explosion chamber are attached to one another by means of an articulated system. 
     
     
         12 . The assembly according to  claim 11 , wherein the support is formed by several straight sections telescopically mounted together. 
     
     
         13 . The assembly according to  claim 10 , wherein the support is formed by several straight sections telescopically mounted together. 
     
     
         14 . An avalanche triggering system comprising:
 the assembly according to  claim 10 , and   at least one member for feeding a gas mixture into the explosion chamber.   
     
     
         15 . The avalanche triggering system according to  claim 14 , further comprising a technical unit integrating at least one of the following elements:
 at least one receiving member for receiving bottles of gaseous fuel and oxidizer,   at least one member for injecting gas inside the explosion chamber,   at least one member for controlling gas injection into the explosion chamber,   at least one ignition member for igniting the gas mixture inside the explosion chamber.   
     
     
         16 . The avalanche triggering system according to  claim 15 , wherein the technical unit is interfaced and placed on the explosion chamber without being attached thereto.
