Definitions

  • This invention relates to a portable unit in which a desired pressure may be maintained, for example for the recovery of divers suffering from the bends.
  • a portable unit in which a desired pressure may be maintained and which is capable of transporting therein a person, the unit comprising a flexible body for housing the person, the body having an entrance forming a hatchway, and a rigid hatch cover for sealing the hatchway, the unit being provided with an inlet for compressed gas and a valve whereby the pressure in the unit may be regulated.
  • the unit of the invention may be submerged to the depth of the diver, who is placed inside the unit.
  • the unit is then sealed and air is drawn from a demand valve to be discharged into the unit.
  • the required pressure may then be set in the unit by means of an adjustable release valve.
  • the air discharged from the demand valve into the unit then causes water in the unit to leave via the release valve.
  • the unit ascends to the surface of the water maintaining the preset pressure.
  • air may be discharged from the demand valve to expel any water from within the unit so that the unit may be transferred with the diver inside.
  • the unit may also be used to transfer a suffering diver for treatment on land.
  • the hatch cover 8 is provided with two handles 9, an adjustable release valve 10 and a 4 inch laminated glass port hole 11.
  • FIG. 6 shows the hatchway 20(which may be aluminium cast and machined for a good fit)fitted into the entrance of the unit.
  • the outer rubber flange 3 fits over the hatchway 20, exposing an interrupted thread 13 for attachment purposes.
  • the body 1 has a steel ring 12 laminated to a flange la of the entrance of the body 1.
  • the hatchway 20 consists of an annular member 14, shown in Figure 7, and, in cross-section, at the lower part of Figure 11.
  • This annular member 14 is provided in a front face 14a thereof with an annular recess 15 for locating the steel ring 12 in a manner to be described hereinafter.
  • the annular member 14 is further provided with a plurality of screw holes 16 around the circumference of the front face 14a, and carries the interrupted thread 13.
  • the annular member 14 of the hatchway 20 is inserted into the entrance of the body 1 so that the steel ring 12 is located in the annular recess 15. This is shown in Figure 10, and, in more detail, in the cross-section of Figure 12.
  • An inner rubber flange 17 locates the annular member 14 with respect to the steel ring 12, the annular member being secured in place by way of an annular plate 18 (also shown in Figure 8) which is screwed onto the annular member 14 using screws 19 in corresponding holes 16.
  • the unit is shown from the front, with the hatchway 20 thus constructed. As shown in Figure 6, it is protected from the outside by the outer rubber flange 3.
  • the hatchway 20 is now ready to receive the hatch cover 8, shown from the front in Figure 3, from the rear in Figure 4 and from the side in Figure 5.
  • Figure 11 shows a partial cross-section through the hatch cover 8 before it is positioned in the hatchway 20 and
  • Figure 13 shows a cross-section through the hatch cover 8 and hatchway 20, with the hatch cover 8 in position.
  • the hatch cover 8 has two handles 9 and a laminated glass port hole 11 and is provided with an adjustable release valve 10.
  • the circumference of the hatch cover 8 has an interrupted thread 21 to cooperate with the interrupted thread 13 on the hatchway 20.
  • the adjustable release valve has an outlet 22 provided with a filter 23 ( Figure 13).
  • a rubber seal 24 is provided between the port hole 11 and main body of the hatch cover 8 .
  • the length of the unit is 7' ( ⁇ 2 m)
  • the body 1 and hatchway 8 once constructed, may be stored in a conveniently sized container (for the embodiment illustrated above having the dimensions 26" (66cm) x 26" (66cm) x 18" (45.7cm), and weighing only 65lbs (29.5kg)).
  • the hatch cover 20 may be attached to the hatchway 8 by arranging for one part of the interrupted screw thread 21 on the hatch cover 20 to face a space between the parts of the interrupted screw thread 13 of the hatchway 8, inserting the hatch cover 20 into the hatchway 8 and twisting it so that the screw threads engage. To remove the cover 20 the reverse procedure is carried out.
  • a diver may draw air from the demand air valve (not shown), exhaling the air into the unit to inflate it to the required pressure.
  • the adjustable release valve 10 is set, from outside the unit using a gauge 10a, at the required pressure so that excess air or water, as the case may be, is discharged via the valve 10.
  • the bottles 6 may be easily replaced if necessary.
  • the two air bottles 6 are removed and the body 1 is rolled up to be placed in a storage container with the air bottles 6.
  • the described embodiment can operate at pressures between 14.7 lbs psi Hl bar) and 30 lbs psi ( ⁇ 2 bar), and may be quickly assembled ( in about 3 minutes) for use.
  • divers need no longer be submerged unconscious, to a required depth of water but may be placed in the unit and moved for treatment without further risk.
  • the diver's equipment may be removed when the diver is in the unit.
  • the unit described above may be carried by hand without difficulty and assembled quickly for a recovery operation.
