Definitions

  • the present invention relates to a fire hose comprising a safety device to prevent it from moving under the action of water ensuring its supply.
  • the part of the butterfly which is upstream of the pivot axis of the pins, relative to the direction of water flow, is directed downwards.
  • the fire hose according to the invention has a stop which, when the water does not circulate, maintains the butterfly in a rest position in which the trigger is away from the ground.
  • the trigger remains above the soil when water does not circulate, and therefore does not risk to be soiled or damaged when the lance is not used.
  • the stop can advantageously be carried by the part of the butterfly which is downstream of the pivot axis of the trunnions, by relative to the direction of water flow, and lean against the inner face of the tubular body to keep the butterfly in its rest position.
  • the stop Being inside the body of the lance, the stop is perfectly protected against the risks of original deterioration external.
  • the rod may also have at its end opposite to the hook an end piece leaning against the ground when the butterfly is in the open position.
  • the fire hose that can be seen in Figure 1 is distinguishes from conventional lances only by the device of security 1 which is provided at its entrance and through which it is connected to a water supply pipe 2.
  • the safety device 1 comprises a tubular body 3 connected to the pipe 2 by a conventional fitting 4, this fitting being consisting of two complementary elements carried respectively by the tubular body 3 and the pipe 2.
  • the tubular body 3 contains a butterfly 5 movable between an open position (visible in Figure 3) in which it allows water circulation and a closed position (visible in Figure 5) in which it limits this circulation.
  • the butterfly 5 is carried by two coaxial journals 6 mounted pivoting on the tubular body 3, on a horizontal axis extending perpendicular to the direction of water flow.
  • the tubular body 3 has a circular cross section and is crossed diametrically by the pivot axis of the pins 6, as clearly shown in Figure 2.
  • the safety device 1 also comprises a lever external control 7 secured to one of the pins 6, and a trigger 8 carried by the lever 7 and the function of which will be described below.
  • the trigger 8 has for function of keeping the butterfly 5 in its open position when the control lever 7 exerts on it, under the action of the water circulating on the upstream part 5a of the butterfly, a force vertical pressing it against the ground.
  • control lever 7 has at its end closest to the ground an orifice 10 extending parallel to the pivot axis of the pins 6.
  • the trigger 8 it has a rod 8a ending by a hook 8b threaded into the orifice 10, as well as a tip 8c screwed on the rod 8a, on the side opposite the hook 8b, and intended to lean against the ground when the butterfly is in position opening.
  • the trigger 8 could of course be different from that which has just been described.
  • a ball joint device interposed between the lever 7 and the tip 8c could replace the rod 8a without departing from the scope of the present invention.
  • control lever 7 comprises a operating handle 11 at its end opposite to the trigger 8, this handle extending obliquely upward when the butterfly 5 is in its open position.
