Definitions

  • the present invention relates to headgear to be worn by personnel for protection against unpleasant or toxic substances in their local atmosphere, such as radioactive, chemical and/or bacterial substances.
  • headgear in accordance with the invention are hereinafter called respirators.
  • Co-pending UK patent application No. 20135/76 describes a respirator for protection against undesirable substances in a local atmosphere and which comprises a hood and a visor both made of material impervious to the undesirable substance, attached one to another in a manner impervious to the undesirable substance and adapted to fit and envelop closely the head of a wearer, means for permitting a wearer to breathe acceptable air and/or oxygen, means for maintaining a gas pressure within the respirator greater than local environmental pressure, and seal means for preventing atmosphere outside thereof from reaching the interior of the respirator via the neck aperture thereof.
  • respirators The primary utility of such respirators is in the protection of aircrew, particularly military aircrew, and it is a feature of that invention, and indeed of the invention the subject of the co-pending UK Patent Specification 47129/77, that such respirators may be used at all altitudes. Now a significant proportion of aircrew find it necessary to unblock their ears during change of altitude by occluding their noses.
  • the present invention provides on a respirator of the type described in co-pending patent application No. 20135/76 means whereby a user may occlude his nose.
  • a respirator of the type comprising a hood and visor combination for closely enveloping the head of a user and an oronasal mask contained or formed within the hood for delivering breathable gas to the user's nose and mouth, has manually operable nose occluding means including force transmission means penetrating the hood/visor combination, manipulable handle means associated with the transmission means outside the hood/visor combination and nose impingement means associated with the transmission means and within the hood/visor combination, the arrangement being such that in use manual operation of the handle means can bring about the impingement on the user's nose and occlusion thereof by the impingement means.
  • the handle means is located on a nasal region of the visor, the transmission means comprises a pair of pivots, and the impingement means comprises a yoke arranged to swing down onto the sides of the oronasal mask and to pinch it onto the nose.
  • the arms of the yoke may carry rollers rotatable thereon to facilitate a swinging and pinching operation.
  • the handle means is located on the respirator in the region of a hood cavity gas supply inlet, and the nose impingement means comprises a pair of cranks fitted within the mask and the arms whereof are operable in use to swivel one toward the other and pinch the user's nose.
  • the transmission means may comprise an arm/pin linkage or cable, cord, or chain means perhaps with an associated spring for urging the impingement means into a non-impingement configuration.
  • the transmission means comprise a Bowden cable and the handle means a caliper device.
  • the impingement means are preferably readily adjustable so that a user can arrange them to occlude his own nose in optimum fashion.
  • the impingement yoke or arms may be readily detachable, bendable, and/or carry adjustable pads.
  • seals may be included to prevent entry thereby of undesirable substances.
  • the occlusion means are particularly readily mountable on respirators the visors whereof are constituted by a member forming an exoskeleton for covering substantially the whole of a user's face.
  • FIG. 1 is a front elevation of a respirator visor carrying a nose occluder
  • FIG. 2 is a side elevation of the respirator shown in FIG. 1.
  • a visor 10 to a respirator of the type described in co-pending UK patent application No. 20135/76 is a substantially rigid member formed to cover substantially the whole face of a wearer. It is transparent at least in the region ahead of the eyes and forms an exoskeleton to the respirator as a whole. It carried, attached at a face plate 11, an oro-nasal mask 12 formed to cover the nose and mouth of a wearer.
  • the mask 12 is made of a flexible rubber material.
  • Clamping means 13, also attached at the face plate 11 serve, in consort with an anchorage on say an aircrewman's helmet, to urge the mask 12, via the visor 10, to seal against the face of the wearer around the nose and mouth.
  • the nose occlusion facility is mounted on the visor 10 in a nasal region thereof. It comprises a pair of pivots 14 penetrating the visor nasal region on a common lateral axis, a pair of yoke arms 15 mounted on and projecting radially from the pivots 14 inside the visor 10, and a substantially V-shaped handle 16 attached to both pivots 14 outside the visor.
  • the arms 15 carry right cylindrical beads 17 rotatable thereon.
  • the pivots 14 are sealed to the visor.
  • the arms 15 are made of a manually pliable metal so that an individual wearer may bend them to maximise the efficiency of their operation with respect to his own nose.
