Definitions

  • This invention relates to breathing apparatus and more particularly, but not exclusively, is concerned with breathing apparatus for use by fire fighters and the like.
  • fire fighters wear a safety belt for the purpose of, for example, preventing them from falling from ladders, buildings etc during the course of their work.
  • this apparatus comprises a carrying unit including a harness and a source of breathable gas, such as an air line or one or more containers for holding breathable gas under pressure, secured to the carrying unit.
  • the harness ordinarily also includes a waist belt.
  • the fire fighter essentially has two belts around his waist namely the safety belt and the waist belt of the harness of the breathing apparatus carrying unit. This tends to be cumbersome and can cause unnecessary difficulties for the fire fighter.
  • a breathing apparatus comprising a source of breathable gas secured to a carrying unit comprising a harness and means of releasably coupling the carrying unit to a waist belt.
  • the waist belt is a safety belt of the DIN standard type.
  • the fire fighter (or other wearer) is able to attend an incident wearing his safety belt and carry out his normal duties in the usual way.
  • he can merely don the apparatus very readily and attach the same directly to the safety belt by means of the releasable coupling means.
  • the safety belt forms an integral part of the carrying unit of the breathing apparatus as a consequence of the releasable coupling means. However, if desired, the breathing apparatus and harness can be removed without removing the safety belt.
  • the means of coupling the carrying unit to the belt includes a strap, on the harness, carrying the male or female portion of a quick release connector.
  • the waist belt includes a strap carrying the corresponding female or male portion of the quick release connector.
  • the strap of the waist belt may be removably secured to the waist belt by, for example, a two part component capable of being clamped around the belt so that it can be slid along the belt as desired.
  • the means releasably coupling the harness to the waist belt may be in the form of a sliding buckle.
  • the fire fighter may already be wearing his safety belt in which case he can merely don the carrying unit of the breathing apparatus and secure it to the safety belt. Alternatively, he can secure the carrying unit to the safety belt before donning the breathing apparatus and safety belt together.
  • the breathing apparatus comprises a carrying unit to which is attached a container 1 holding breathable gas, such as air, under pressure.
  • the apparatus also includes a demand valve (not shown) and a hose (not shown) linking the container to the demand valve.
  • the carrying unit comprises a back plate 2 and a waist plate 3 to which the container 1 is secured and a harness comprising shoulder straps 4.
  • Each shoulder strap terminates in a loop 4' through which passes the free end of a strap 5 connected to the waist plate 3 by stitching or other suitable means.
  • Each end of the strap 5 has a short length of strap 6 attached thereto and terminates in a female connector portion 7.
  • the fire fighter is additionally wearing a safety belt 8 of the DIN standard type.
  • a component 9 in the form of first and second parts 10 and 11 secured together by nuts and bolts or rivets 12 so that they lie on either face of the safety belt 8 and the component 9 can slide along the belt 8.
  • Secured to the slidable component 9 by, for example, stitching is a short length of strap 13 terminating in a male connector portion 14 corresponding to the female connector portion 7.
  • Two such slidable components 9 are provided one at each of the wearer's sides.
  • the female and male connector portions 7 and 14 respectively together define a quick release coupling.
  • the fire fighter will ordinarily be wearing the safety belt 8 whilst attending to his duties.
  • he finds that he needs the assistance of breathing apparatus, he dons the apparatus by slipping his arms through the shoulder straps 4 of the carrying unit and clips it to the safety belt 8 by engaging the male and female connector portions 14 and 7 at each side.
  • he may secure the carrying unit of the breathing apparatus to the safety belt by means of the male and female connectors 14 and 7 and then don the equipment as a whole.
  • the waist plate 3 includes, at each side of the wearer, a releasable attachment means 21.
  • the attachment means 21 enables the carrying unit of the breathing apparatus to be quickly removably attached to the safety belt 8. More particularly, it includes a swinging arm 22 pivoted at his lower end 23 to the remainder of the attachment. Towards the upper end of the arm 22 there is provided a cutout 24.
  • the attachment includes a plunger 25 which is slidable in a vertical direction with respect to housing 26.
  • the plunger 25 is resiliently biased by means of a spring (not shown) so that it tends to adopt an upper position with respect to the housing 26.
  • the plunger includes a spigot 27 having an inclined surface 28 and a surface 31 serving as a detent.
  • the relative dimensions of the spigot 27 and cutout 24 are such that the cutout 24 can pass over the spigot and be retained therein, by detent surface 31, under the influence of the spring tending to urge the plunger 25 in an upward direction. More particularly, as the arm 22 is pivoted into contact with the spigot 27, the plunger 25 is forced downwardly by the inclined surface 28 against the pressure of the spring and the plunger can then return somewhat to an upper position wherein the detent surface 31 of the spigot 27 retains the arm 22 against the plunger 25. Thus the arm 22 is essentially locked behind the detent surface 31 of the spigot 27.
  • the attachment 21 is secured, by means of bolts or the like passing through fixing holes 29 to the waist plate 3 of the carrying unit.
  • a loop-defining member 32 is secured to the housing 26 and one of the shoulder straps 4 is secured to the member 32.
  • the fire fighter will ordinarily be wearing his safety belt 8.
  • he When he requires breathing assistance, he inserts his arms into the shoulder straps of the carrying unit. The he depresses the plunger 25 of each attachment 21 to release the spigot 27 from the cutout 24 and enable the arm 22 to be pivoted away from the plunger 25 to provide a gap 30. He then manipulates his safety belt 8 into the gap as shown in Figure 4. Thereafter he pivots the arm 22 back into engagement with the plunger 25 where it is retained by the cooperating cutout 24 and spigot 27. In order to disconnect the carrying unit from the safety belt, downward pressure is placed on each plunger 25 which enables the cutout 24 to ride over the spigot 27 so that the arm 22 forms the gap 30 with the housing 26 and the unit can then be lifted off the belt 8.
  • the carrying unit may be clipped to the safety belt and then the fire fighter can don the whole equipment as an integral unit by slipping his arms through the shoulder straps and attaching the safety belt to his waist.
  • the entire unit comprising the breathing apparatus and the safety belt can be removed together as an integral unit.
