Definitions

  • the present invention relates to a safety device against avalanches.
  • the aim of the present invention therefore is to eliminate the aforementioned drawbacks.
  • the invention such as it is characterised by the claims, solves the problem of signalling one's position if one is swept away by an avalanche and simultaneously allowing to maintain one's head as high as possible with respect to the surface of the snow.
  • One of the advantages obtained by means of the present invention consists essentially of the fact that sighting a victim is enormously facilitated. Moreover, buoyancy is increased, in particular locating it below head level.
  • the invention concerns a safety device against avalanches, comprising a support (1) provided with means for fastening (2) to a user of the device (10), an inflatable balloon (3) and related means (4) for inflating the balloon (3), able to allow the balloon (3), once inflated, to rise freely whilst remaining attached to the support (1).
  • the support (1) is applied to a trekking backpack and the means for fastening (2) to the trekker comprise shoulder straps and/or belts.
  • a housing space (6) for the deflated balloon (3) is provided, hermetically sealed.
  • the trekker activates a command (7) to open the housing space (6) of the balloon (3), which, in the example shown in the figures, is a manual control (7) comprising a rip lever.
  • the activation of the manual command (7) causes the balloon to be inflated and subsequently expelled.
  • the means (4) for inflating the balloon (3) comprise at least one small gas tank (17) and a device (16) for opening it.
  • the latter in turn comprises a spring-operated percussion pin (18), housed in a conduit (20) for the passage of the gas interposed between the gas tank (17) and the balloon (3), and a fork (19) inserted from outside through appropriate holes (21) of the aforesaid conduit (20) and connected to the manual command (7), which governs its activation.
  • the fork (19) disengages the conduit (20) and the spring-operated percussion pin punches a hole in the tank, thereby freeing the gas contained therein, as Figure 3 shows.
  • a sealing device (22) is mounted, comprising a second spring (23) and a seal ring (24), also activated by the fork (19).
  • the second spring (23) thrusts the seal ring (24) against an enlargement (25) obtained on the outer surface of the conduit (20) obstructing the holes (21).
  • the extendible attachment means (5) for instance consisting of a plastic line provided with good tensile strength, unwind over their entire length thereby allowing the balloon to rise and remain above the surface of the snow, being visible even from a distance.
  • the means (4) for inflating the balloon (3) can indifferently remain attached to the balloon (3) or to the support (1): in the latter case, shown also by way of example in
  • the device (10) comprises means (8) for releasing the balloon (3) from the means for inflating it.
  • They comprise a foil (26), integral with the means (4) for inflating the balloon (3), which engages in a recess (27) obtained at the base of the balloon (3), on a rigid collar (28) integral whereto, a third spring (30) fastened to the foil (26), a holding pin (29) to maintain such spring compressed (30) and a non-rigid constraint (31), for instance a line, interposed between the balloon (3) and the pin (29).
  • the spring (30) is free to extend and extracts the foil (26) from the recess (27), thereby allowing the balloon (3) to be freed from the means for inflating it.
  • the safety device (10) constituting the subject of the present patent is advantageously fitted with an inflatable cushion (9), comprising at least two arms (12) with lateral development with respect to the user's body, preferably provided with front projections, positioned below head level, to provide an additional upward thrust to the support, favouring its flotation.
  • these arms (12) are bent into a "U" shape to encompass the user's head. Moreover, they are provided with respective fastening means (13), such as Velcro surfaces, so positioned as to interact upon completion of the inflation of the cushion (9), in correspondence with the projections.
  • fastening means (13) for inflating the cushion (9) for instance comprising a second small gas tank are used.
  • the support (1) could also comprise two detachable parts (1a,1b), between which it is housed when deflated, which detach when the cushion (9) inflates, remaining attached to the part (1a) of the support (1) in contact with the user.
  • a preferred embodiment provides for the cushion (9) to comprise two veritable independent arms (12), each housed in a pouch (32) of fabric which can be torn by ripping.
  • Said pouches are advantageously realised in correspondence with the horizontal belt (33) of the backpack and each arm (12) comprises its own inflating tank (34), filled with carbon dioxide or other similar gas.
  • the material of the balloon (3) is polyethylene, i.e. of the type usable for aerostatic balloons, very light and with minimum volume when deflated, but very resistant nonetheless. In this way, the balloon (3) can be reduced in an extremely small housing space (6), inside a small vertical cylinder (66), positioned at the top of the support (1), where a tear-off fabric (36) is provided.
  • the cylinder (66) is placed in communication with its own tank (17), filled with helium, through a tube (35) which, upon activation of the manual command (7), allows the inflation of the balloon (3) which, automatically while it inflates, comes out of its containment cylinder (66), the tear-away fabric (36) having been ripped apart and, once inflated, starts its upward run, held only by the extendible attachment (5), collected in a simple and small spool (37) - see Figure 2a.
  • the three gas tanks (34 and 17) are activated together and both the fabrics of the pouches (32) and the fabric (36) are torn apart, which frees the balloon (3), at a single stroke.
  • the gas tanks are advantageously positioned vertically side by side, with the central one (17) oriented towards the polyethylene balloon (3) and the other two with their mouths facing downward and oriented towards the respective arms (12) to be inflated.
