Definitions

  • the present invention relates to a system for perforating a gas cartridge, making it possible to release, if necessary, a compressed gas (generally CO2) contained in said single-use cartridge, in order to actuate various pneumatic elements , in particular devices ensuring safety in the event of fire, and more particularly smoke extraction systems.
  • a compressed gas generally CO2
  • the compressed gas cartridges currently used are closed by a cover, generally metallic, which is perforated, during use, by a striker provided with a tip of suitable shape, provided on the perforation system.
  • a cover generally metallic, which is perforated, during use, by a striker provided with a tip of suitable shape, provided on the perforation system.
  • the gas cartridge As soon as the gas cartridge has been used, it must be replaced by a new cartridge filled with compressed gas and closed with a blank seal, in order to return to the standby position the entire control and safety system constituted by the striker and the pneumatic elements of the safety device, the latter then being again ready to be actuated.
  • the document FR-A-2263004 describes a type of safety equipment which makes it possible to visually control the state of the sealing cap of the gas cartridge and, consequently, to realize by a purely optical examination, if the safety device gas cartridge is empty or full.
  • this type of material it is possible, with this type of material, that the cartridge is empty or absent, while the striker is apparently armed. It follows from this drawback that a smoke extraction installation fitted with such a device can prove to be dangerous because it does not work in the event of a disaster.
  • the present invention has therefore set itself the objective of providing a gas cartridge perforation system offering the certainty, by a simple visual observation, that the striker is provided with a cartridge with a blank lid, therefore full of compressed gas.
  • this invention as described in rev. 1 relates to a system for perforating compressed gas cartridges closed by a cover, generally metallic, using a striker provided with a tip of suitable shape, which makes it possible to achieve the abovementioned objective.
  • the percussion system of the gas cartridges comprises a body 10 provided with a longitudinal axial bore 12 in which the rod 14 of the striker, provided with a tip 16 of suitable shape, designed so as to perforate the cover 18 which closes, as known, the compressed gas cartridge 20.
  • the end of the cartridge 20 provided of the obstructing cover 18 is screwed onto the body 10 with an interposition of a seal 22.
  • a sleeve 26 returned by a spring 28, the relative arrangement of this sleeve 26, the striker rod 14 and the spring 28 being such that the action of the spring s 'exerts on the cover 18 by the sleeve 26 and not by the tip 16 of the striker.
  • a clearance "j" is provided between the sleeve 26 and the tip 16, the distance “d” (FIG. 1) representing the stroke of the striker tip.
  • the striker rod is actuated manually using a lever 30, pressing on the head 32 of the rod 14, as will be seen below.
  • the body 10 is provided with a blind bore 34 receiving a locking rod 38 at the end 38 in the form of a piston returned by a spring. 40, the end 38 of the locking rod being arranged so as to be able to engage, at least partially, in a groove 42 provided in the head 32 of the striker rod.
  • Figures 5 and 6 show the system according to the invention, without the compressed gas cartridge. It can be seen that the sleeve 26, pushed back by the spring 28, is lowered at the end of the stroke, by driving the rod 14 of the striker by the pin 13, and that the locking pin 36-38 is housed in the groove 42 of the head 32, the lever 30 being in the low position.
  • the observer detects, without risk of error, that the system is not in the waiting position.
  • Optical observation of the position of the lever 30 can be facilitated using a mechanical or electrical indicator light, controlled by an electrical contact actuated by the system.
