Definitions

  • the present invention relates to the sector of pneumatically supported self supporting equipment and in particular relates to a device for inflating field tents, mainly designed for civil defence activities.
  • the means for pressurising the air consist of conventional fan devices, powered with electricity supplied by a fixed supply network or by a local generator.
  • the fan unit automatically adjusts its number of revolutions so as to compensate for a drop in internal pressure which may occur for the most diverse reasons, including for example air leaks through transit openings in the tent and/or through seams connecting the various sections of the tent surface.
  • first aid and emergency situations for example when faced with particularly intense and serious natural events such as earthquakes, floods, etc. - it may be the case that the first aid support field must be set up in the absence of electricity. Said absence is due to the fact that the fixed electricity network is unavailable locally or, even if present, is temporarily not working.
  • the main aim of the present invention is to overcome said disadvantages with a pressurising device which allows: extremely rapid tent set up, irrespective of the presence or absence of a local electricity supply, and without using a safety structure designed to prevent sagging.
  • the invention also has for an aim to also allow tent rapid depressurisation, which may be particularly advantageous for speeding up tent disassembly, allowing a rapid reaction to an unforeseen emergency, or for more rapidly moving camp from one site to another.
  • Another aim of the invention is to provide a compact, easily manoeuvrable autonomous device.
  • the invention relates to a device for pressurising pneumatically supported self-supporting structures whose technical features are described in claim 1 and/or any of the claims from 2 to 9 which are directly or indirectly coordinated with it.
  • the numeral 1 denotes a device for pressurising a pneumatically supported self-supporting structure 2, in particular a field tent.
  • Figures 2 and 3 provide better views of the device 1 which basically comprises an autonomous unit 3 having a casing 8, mounted on wheels 10 and equipped with a handle 11 for moving it.
  • the casing 8 houses mechanical ventilation means 6 and 7, connected to an air intake section 4 and a pressurised air delivery section 5, made in a wall 9 of the lateral surface of the casing 8.
  • the autonomous unit 3 also houses in the casing 8 battery means 12 for accumulating electricity, operatively connected to the mechanical ventilation means 6 and 7. It also contains electric recharging means 13, designed to connect the battery means 12 to an external electricity supply, when available, for recharging the battery means 12.
  • the mechanical ventilation means preferably comprise two centrifugal fans 6 and 7, driven by direct current motors with two operating speeds at 12/24 Volts.
  • the centrifugal fans 6 and 7 are operatively connected to the air intake section 4 and pressurised air delivery section 5.
  • the two fans 6 and 7 are preferably abutted to a pressurised air delivery section 5 and an air intake section 4.
  • the intake section 4 takes air directly from the environment immediately surrounding the unit 3, whilst in contrast the delivery section 5 is connected to a mating inflation opening made in an outer wall 21 of the self-supporting structure 2, so that subsequent activation of the fans 6 and 7, controlled using suitable selector means 14 connected to the wall 8 of the unit 3, allows gradual pressurisation of the self-supporting structure 2.
  • the possibility of activating one fan 6 and 7 at a time means that, should a fault occur in one fan, the other can immediately be activated, without interrupting the service, and/or without having to provide safety structures to prevent sagging of the pneumatic self-supporting structure 2.
  • the unit 3 also allows inversion of the fluid dynamic connections of the fans 6 and 7 with the intake section 4 and the delivery section 5. This means that the fans 6 and 7 can suck air out of the pneumatic structure 2 internal compartment and expel the air towards the surrounding outside environment.
  • the fans 6 and 7 can also be used to rapidly deflate the pneumatic structure 2, for example when rapid dismantling of the structure 2 is required.
  • the electric recharging means 3 may be of the type designed to operate with current intensity of approximately 10 A. When an external electricity supply is available, said means may reserve part of the current intensity (5A) for powering the fan motors and part (5A) for recharging the battery means 12.
  • the battery means may be for example sealed, maintenance-free batteries which, with limited weight, allow the device 1 to operate, in the absence of an external electricity supply, with an autonomy of around 8 to 10 hours.
  • the device 1 according to the invention has proved able to fulfil the aims and to operate efficiently and rapidly, allowing structure 2 inflation times of around 5 to 10 minutes, whilst deflation mechanically assisted by the fans 6 and 7 may be performed in around 12 to 15 minutes.
