  • respirator of this type is described in the document DE 39 37 513 .
  • the object of the invention is therefore to allow a quick and easy change of the bottle, directly on the back of the wearer, that is to say without requiring removal of the device.
  • the invention relates to a breathing apparatus of the aforementioned type, characterized in that the connector comprises an air intake tube protruding outwards, on which a sleeve is pivotally mounted and displaceable in axial translation, the sleeve having a first externally threaded zone, located on the side of the free end of the pipe and intended to cooperate with the threaded housing of the valve of the cylinder, and a second zone, intended to be mounted in a jacket forming operating button, the socket forming a screw being locked in rotation in the liner and free in translation with respect thereto, the liner being mounted pivoting on the fitting around the axis of the tubing and locked in translation vis-à-vis thereof.
  • the housing of the valve is positioned on the free end of the pipe, thereby achieving a centering of the valve relative to the socket screw, the valve pushing the latter in the direction of the backsplash.
  • This provides a connection that is easy to use since the valve positioning operations relative to the connection and screwing are dissociated, the tubing to form a support before screwing.
  • the free end of the tubing comprises a zone of diameter substantially equal to the diameter of the tap housing.
  • the length of the tubing is at least equal to the depth of the housing, increased by the length of the screw bushing.
  • an elastic member in particular a helical compression spring, is mounted between the expander or the sleeve and the sleeve.
  • the elastic element thus constrains the bushing, more precisely the threaded zone thereof, against tap threading, to initiate their screwing during the rotation of the sleeve and the sleeve.
  • the length of the liner is at least equal to the length of the sleeve.
  • the end of the sleeve thus exceeds the socket during the insertion of the valve, so that the jacket can also participate in guiding the valve.
  • the sleeve is equipped with a coupling rod, for example a screw, extending radially outwards, the rod being inserted into an oblong slot in the sleeve.
  • a coupling rod for example a screw
  • Such coupling is simple and allows to bind the sleeve and the sleeve in rotation, while allowing a translation of the sleeve relative to the sleeve.
  • the sleeve is equipped with locating elements protruding inside the oblong slot.
  • the marking elements thus visible from the outside by the operator making the screwing of the bottle on the tap, make it possible to better visualize the position of the socket and thus to ensure that the screwing is correctly carried out.
  • the breathing apparatus comprises a hood, fixed on the backrest and covering at least partly the latter and the regulator.
  • the breathing apparatus comprises a bottle support having at least three support points positioned so as to define a V oriented perpendicularly to the plane of the backsplash, intended to support a bottle.
  • the support in V allows a good setting of the bottle, whatever the diameter of this one.
  • the support comprises two additional lateral support points, each being intended to support a bottle.
  • the figure 1 represents a breathing apparatus 1 according to the invention, of the open circuit type, in position on the back of a wearer.
  • the wearer is equipped with a helmet 2, on which is fixed a waterproof mask 3 covering the face, in particular the airways of the wearer.
  • the latter is also equipped with a breathing apparatus 1 having a backsplash 4, equipped with straps 5 passed around the shoulders and at the waist,
  • the splashback supports a bottle 6 forming a supply of compressed air, equipped with a valve 7 having a threaded internal housing, as is known per se, the valve cooperating with a connector 8 which, mounted on the backrest 4, is connected to a regulator, visible in reference 9 in particular in figure 4 .
  • a flexible pipe 10 makes it possible to bring the air coming from this high-pressure regulator 9 to a second expander 11, called a low-pressure regulator, fixed on the mask of the carrier 3 and making it possible to relax the compressed air to a slight pressure. above atmospheric pressure.
  • a demand valve 12 further allows the air to be introduced into the air mask 3 when the wearer is inhaling, and to reject the exhaled air.
  • control and alert 13 make it possible to inform the wearer on the remaining capacity of the bottle 6 and / or to display indicators of the ambient environment.
  • the backsplash 4 equipped with the connector 8 further comprises a cover 14 from which a bottle support 15 projects.
  • the cover 14 covers the majority of the backsplash 4 and has an opening 16 at the bottom part for the passage of the connector 8 connected to the regulator (not visible), protected by the hood.
  • the figure 3 shows the breathing apparatus 1 equipped with a bottle 6 fixed to the backrest 4 by means of a ratchet strap 17, as is known per se, and resting on the support.
  • the valve of the bottle 7 makes it possible to connect the mouth of the bottle 6 and the connector 8 via a valve 18.
  • the Figures 4 to 7 show in detail the expansion valve 9 equipped with the connector 8.
  • the latter comprises an air intake pipe 19 protruding outwards, on which a sleeve 20 is pivotally mounted and movable in axial translation.
  • the sleeve 20 comprises a first zone 21 externally threaded, located on the free end of the tubing side 19 and intended to cooperate with the threaded housing 22 of the valve 7 of the bottle 6, as described below.
  • the sleeve 20 further comprises a second zone 23, intended to be mounted in a sleeve 24 forming an operating knob.
  • the bushing 20 is locked in rotation in the sleeve 24 and free in translation vis-à-vis thereof.
  • This rotational coupling is achieved by means of screws 25 fixed in the second zone 23 of the bushing 20, the head of the screw being guided in translation by an oblong slot 26 formed in the liner 24, the axis of the light being parallel to the axis of the tubing.
  • the bushing 20 further comprises locating elements protruding in the oblong slot, integral with the second zone 23 of the bushing 20.
  • the liner 24 is further pivotally mounted about the axis of the tubing 19 and locked in translation vis-à-vis thereof.
  • the threaded zone 21 of the bushing 20 and the liner 24 further define an annular space, of external diameter greater than the outside diameter of the valve 7, in its zone 27 intended to cooperate with the connector 8, and of internal diameter substantially equal to the diameter of the housing 22 of the tap 7.
  • a helical compression spring 28 is disposed between the liner 24 and the bushing 20, so as to constrain the bushing 20 against a shoulder 29 of the air intake manifold 19, made at the free end thereof. this.
  • the external diameter of the tubing 19, at its end zone delimited by the shoulder 29, corresponds substantially to the diameter of the threaded housing 22 of the valve 7, for reasons which are detailed below.
  • the length of the sleeve 24 is greater than that of the sleeve 20 and the length of the tube 19 is greater than the length of the sleeve 20, increased by the depth of the housing 22 of the valve 7.
  • valve 7 When positioning the valve 7 on the connector 8, as shown in FIG. figure 6 , the inner housing 22 of the valve 7 cooperates with the air inlet pipe 19 until the end of the latter comes into abutment against the bottom of the housing 22.
  • the bushing 20 is located entirely inside the liner 24 and its threaded zone 21 is constrained against the tapping 22 of the valve.
  • the bushing 20 By rotation of the liner 24, the bushing 20 is then screwed onto the valve 7. During screwing, the bushing 20 mounted displaceable in translation along the air inlet pipe 19, translate towards the free end of it.
  • the figure 7 corresponding to the figure 6 , represents the position of the sleeve 20 at the end of screwing.
  • the marking elements 30 make it possible to better visualize the positioning of the socket during screwing and / or unscrewing, so as to ensure that the valve 7 is correctly screwed onto the coupling 8.
  • connection 8 makes it possible, in a first step, to correctly and easily position the valve 7 on the pipe 19, the latter forming a support, in particular when the bottle 6 exerts a force directed vertically downwards on the valve 7, then proceed to the screwing step, regardless of positioning.
