Definitions

  • the invention relates to a breathing apparatus as an escape device with pendulum breathing according to the preamble of claim 1.
  • Respiratory protective devices of the type mentioned at the outset are accommodated in airtight lockable standby containers which are used, for example, in mine operations, are constantly carried by the miner and are worn on the body. The device is removed from the standby container for use.
  • 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-248504).
  • a relatively high-profile housing cover is required, which thus substantially determines the overall size of the standby container, so that the breathing apparatus with the standby container must be worn on the body by means of a shoulder strap.
  • this device carrying method is difficult for the miner who is always carrying the device.
  • a breathing apparatus 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-shaped clamps (US-A-2492272).
  • the volume of the breathing bag that is effectively available for collecting breathable air extends as an elongated bag shape below the chemical cartridge.
  • the invention is therefore based on the 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.
  • the advantages achieved by the invention are, in particular, that the size of the breathing apparatus is reduced, and moreover, the surface temperature of the device is advantageously reduced by the special arrangement of the chemical cartridge without firm contact with the breathing bag enveloping the cartridge. Furthermore, the insulating arrangement between the heat exchanger and the chemical cartridge, despite the compact design of the device, also lowers the temperature of the inhaled air.
  • 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.
  • FIG. 1 shows a schematic representation of the breathing apparatus according to the invention with pendulum breathing.
  • a breathing apparatus with pendulum breathing is shown.
  • the respirator consists of an oxygen-evolving chemical cartridge 1, a heat exchanger 2, which is housed in a housing 3 and rests on heat-insulating spacers 4, thereby avoiding thermal contact with the chemical cartridge 1, a heat-insulating sleeve 5 which surrounds and carries the chemical cartridge 1 in a lining-like manner , a breathing bag 6, which completely envelops the chemical cartridge 1 with the sleeve 5, and a breathing tube 7 with a mouthpiece 8, which is connected to a pipe socket 3a of the housing 3 by means of a constriction 10.
  • the housing 3 of the heat exchanger 2 forms the upper end of the casing 5 for the chemical cartridge 1 and is connected to a flange part 5a of the casing 5 by means of a clamp 9. In this way, there is no fixed connection between the chemical cartridge itself and the breathing bag, so that the heat emitted by the chemical cartridge during operation is more conveniently kept away from the surface of the device.
  • the casing 5 has a plurality of openings 5e on the lower end face 5d in the region of the outlet opening 1b of the chemical cartridge 1 for the exhaled and inhaled air to flow through.
  • the flow through the chemical cartridge 1 is indicated by the arrows.
