Definitions

  • the invention relates to a respirator as an escape device with pendulum breathing according to the preamble of claim 1.
  • Respirators of the type mentioned are housed in airtight lockable standby containers that are used for example in mine operations, carried by the miner at all times and worn on the body. The device is removed from the standby container for use. It is obvious that such a respirator must be light and small for constant carrying in terms of weight and dimensions.
  • the breathing bag is arranged above the chemical cartridge, the chemical cartridge in the lower housing part and the breathing bag with the breathing tube and mouthpiece in the housing cover (SU-A-248 504).
  • a breathing apparatus is also known in which a tubular breathing bag is drawn over the surface of the chemical cartridge and attached to it by means of two metal strip clips (US-A-2 492 272).
  • the volume of the breathing bag that is effectively available for collecting breathable air extends as an elongated bag shape below the chemical cartridge.
  • a breathing apparatus in which an oxygen-developing chemical cartridge is connected directly to a half mask, which in turn is arranged inside a breathing bag and is completely enveloped by it (DE 2 504 881-AI).
  • a breathing apparatus in which a breathing bag is arranged below the chemical cartridge and on the side of the cartridge opposite the breathing tube connection (DE 1 132 802-AS).
  • the chemical cartridge is surrounded at a distance from the cartridge casing with curved sheets, on the outside of which a casing made of a heat-insulating fabric is arranged. This serves as protection against accidental contact, in which the heat is dissipated by the chimney effect.
  • the invention has for its object to provide a particularly space-saving and compact design for an oxygen self-rescuer as an escape device and to save space so that the device can be accommodated in a standby container to be worn on the belt of the device wearer. Furthermore, the heat load due to the exothermic direction of the oxygen-evolving chemical for the breathing bag enveloping the chemical cartridge is said to be low in the operating state.
  • the advantages achieved by the invention are, in particular, that the size of the breathing apparatus is reduced and the device can thereby be accommodated in a small spare container to be worn on the belt.
  • the surface and temperature of the breathing apparatus is advantageously reduced by the complete and double wrapping of the chemical cartridge, namely by the cover and by the breathing bag.
  • the invention has surprisingly shown that it is possible to arrange the chemical cartridge inside the breathing bag, although it was to be expected that the heat emitted by the chemical cartridge during operation would be an unbearable burden for the breathing bag and for the breathing air in the breathing bag. It was to be assumed that, as before, because of the known heat load for the breathing bag, it must be arranged separately from the chemical cartridge as the heat source.
  • a breathing apparatus according to the invention is shown with pendulum breathing.
  • the breathing apparatus consists of an oxygen-evolving chemical cartridge 1, which is closely enclosed by a heat-insulating and shock-absorbing coating 2, a breathing tube 3 with a mouthpiece 4, a breathing bag 5 connected to the chemical cartridge 1 and a carrying strap 6.
  • the breathing apparatus is in a standby container 7 after Fig. 4 housed.
  • a heat exchanger 12 is arranged above the inlet opening D of the chemical cartridge 1 and is designed such that there is no thermal contact between the heat exchanger 12 and the chemical cartridge 1 can kick.
  • the heat exchanger 12 is surrounded by a heat-insulating housing socket 17 which rests captively on the top of the chemical cartridge 1.
  • An opening 5b is provided on the upper end face 5a of the breathing bag 5, through which the chemical cartridge 1 is inserted into the breathing bag.
  • the opening 5b is bordered by a web 5c, to which the chemical cartridge 1 with the cover 2 and the ends of the carrying strap 6 are fastened by means of a collar 22.
  • a pressure relief valve 8 is arranged on the upper end face 5a of the breathing bag 5.
  • the coating 2 shows a cross section through the chemical cartridge 1 with a coating 2.
  • the coating 2 has ribs 2a, which lie at a distance from one another on the chemical cartridge outer surface A in the vertical or longitudinal axis.
  • the lower end face of the chemical cartridge 1 is partially covered by the coating 2, so that the outlet opening B of the chemical cartridge is freely accessible to flow through the exhalation and inhalation air (Fig. 1).
  • the upper end face of the cartridge 1 is completely covered by the cover 2, which preferably forms a unit with the breathing tube 3.
  • the coating 2 consists of a heat-insulating material, for example silicone elastomers. This coating 2 contributes to the fact that in the operating state the heat load due to the exothermic reaction of the oxygen-developing chemical is low for the breathing bag 5 enveloping the chemical cartridge 1.
  • the formation of the coating 2 with the ribs 2a resting on the chemical cartridge outer surface A creates spaces C (see FIG. 2) all around between the outer wall A of the cartridge and the coating 2, which serve as thermal insulation and the surface temperature of the cartridge 1 reduce.
  • the formation of the cover 2 with the ribs 2a also has other advantages: the covering of the cover 2 over the chemical cartridge 1 during assembly is facilitated. Weight reduction for the cover 2, so that the weight for the device to be worn on the belt becomes smaller. The rigidity of the coating 2 is increased. Overall, the cover 2 also serves as shock protection for the breathing apparatus which is accommodated in the standby container 7.
  • the air outlet surface E is advantageously loosely surrounded by cotton wool 9 holding the dust.
  • the air outlet opening B of the cartridge 1 is covered by a sieve 10 protruding into the opening at an acute angle, the molten chemical into a collecting trough formed in the chemical cartridge 1 at the bottom 11 can drain without clogging the flow path.
  • FIG. 3 shows the breathing apparatus in the standby container 7.
  • the lower part of the standby container and 14 its lid are designated by 14. Both parts are pressed airtight against each other by known closure members (not shown).
  • the standby container 7 is provided with an eyelet part 16 in order to be hung on the waist belt of the device wearer.
  • the breathing apparatus must be stored in a shockproof manner in the standby container 7. This is advantageously done by beads 2c formed all around on the cover 2 at the top and bottom.
