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.
  • this invention 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, characterized in that it comprises: - A body provided with an axial bore in which is housed a rod whose tip comes to bear on the cover of the compressed gas cartridge; - a control lever acting on the end of the rod, or integral with the latter, the position of which makes it possible to check whether the seal of the cartridge in place in the system is blank; - an appropriate mechanism, using intrinsic energy such as gravity, gas expansion, a spring acting on the rod or the control lever, intended to prohibit the system from being in the waiting position while the cartridge is missing or perforated; and a device preventing any return to the standby position of the system under the effect of the thrust of the gases released by the perforation of the cartridge seal, said device having to be disengaged for the installation of a replacement cartridge , which puts the system in the standby position.
  • 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 to perforate the cover 18 which closes, as known, the compressed gas cartridge 20.
  • the end of the cartridge 20 provided of the obstructing cap 18 is screwed onto the body 10 with the 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 tip of the striker.
  • 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.
  • the end 38 of the hoisting rod 36 recalled by the spring 40, is housed in the groove 42 of the head 32 of the striker rod while preventing the gas pressure from raising the rod 14. Taking into account the link thus produced between the striker rod 14 and the control lever 30, it is not possible to simulate the fact that the cover 18 of the cartridge in place in the system has not been perforated, because the lever 30 cannot be held in the high position due to its mass and possibly a return spring.
  • 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.
