Definitions

  • the present invention relates to a respirator and more particularly (but not exclusively) to those respirators known as half-mask respirators which are intended to cover only the nose and mouth of a wearer.
  • a respirator having a cup-like body associated with an air inlet and an air outlet and having a peripheral sealing element shaped for location across the nose and around the mouth of a wearer, wherein the sealing element is located in position by a clamping element which is releasably secured on the cup-like body.
  • the cup-like body and clamping element each have flanges which come into face-to-face clamping relationship when the clamping element is mounted on the body, and the seal has a skirt or the like which is clamped between these flanges to retain the seal in position.
  • Fig. 1 is an exploded perspective view of one embodiment of half-mask respirator in accordance with the invention
  • Fig. 2 is an exploded, part-sectional side view of the mask shown in Fig. 1, but omitting details of the harness;
  • Fig. 3 is a side view of the assembled mask.
  • the illustrated half-mask respirator comprises a cup-like body 1 shaped for location over the nose and mouth of a user, a cushion-like face seal 2 for location on the cup 1, an outer clamping element 3, a standard filter cartridge 4, an inhalation valve 18
  • Cup 1 is a rigid plastic moulding formed as a cup-shaped body 7 having an aperture 8 in a flat frontal face thereof and two apertures 9 in a flat basal face thereof.
  • Aperture 8 is extended inwardly by an internally screw-threaded tubular projection 8a in which an air inlet valve 18 (see Fig. 2) is located.
  • Projecting . laterally from the rim of the body 7 is an integral flange 10.
  • Clamping element 3 is also a rigid plastics moulding and comprises a wall 11 with a stand-off guard portion 12. More particularly, wall 11 is shaped to be a close fit around the body 7 save that the guard portion 12 will stand slightly clear of the flat basal face of body 7 to allow the exhaust valves 5 to be positioned in apertures 9. The basal surface of guard portion 12 is slotted so as to allow- passage ⁇ of air from valves 5.
  • clamping element 3 Also provided on clamping element 3 is a flange 13 integral with the wall 11. Finally, stud-like 5 projections 14 are provided on wall 11.
  • Complimentary snap-fit formations are provided on the wall 11 of clamping element 3 and on the body 7 of cup 1 whereby clamping element 3 is a snap fit on cup 1.
  • the snap fit formations may
  • cup-like body 7 may have a contiuous or discontinuous undercut in which a complimentary projection on the inner surface of wall 11 locates.
  • element 3 snap-fitted on cup 1, the flanges 10 and 13 are in
  • Face seal 2 is of the form illustrated in Fig.
  • Seal 2 is formed of a core ring of soft foam-rubber 15 clad
  • This PVC cladding 16 has a skirt 17 (the purpose of which will be described) provided around the inner periphery of the ring-like face seal body and extending inwardly thereof.
  • 25 width of skirt 17 is substantially the same as that of flanges 10 and 13.
  • face-seal 2 is mounted on the cup 1 by manipulating the skirt 17 of seal 2 such that it overlies flange 10 of cup-like body 1. With the seal 2 so mounted on cup 1, a substantial part of the seal's ring like body is located on the side of
  • clamping element 3 is snap-fitted onto cup 1 thus ensuring that skirt 17 is securely clamped between flanges 10 and 13 thereby fixing seal 2 in position.
  • guard portion 12 serves to protect valves 5 whilst allowing passage of air from the valves 5.
  • Assembly is completed by screwing cartridge 4 into projection 8a and finally attaching harness straps 6 to studs 14.
  • the assembled mask is of cou_.se worn with the seal 2 locating over the bridge of the nose and around the mouth of a wearer, the mask being supported in position by the harness straps 6 locating around the back of the wearers head.
  • these harness straps 6 pulsel' the clamping element 3 towards the face of the wearer thus enhancing the clamping action.
  • seal 2 will lose its effectiveness after repeated usage of the mask.
  • the seal may be replaced quickly and easily by releasing and removing clamping element 3 from cup 1 (after removal of cartidge 4 if necessary), removing the old seal, fitting a new one, and re-assembling the mask. Consequently there is no need to dispose of the mask once the seal loses its effectiveness.
  • the illustrated mask has a cushion-like seal.
  • Other types of seal could however be used, e.g. inflatable seals or reflex-edge seals..
