Definitions

  • Inflatable life-jackets are conventionally equipped so that they can be quickly inflated by air or by the compressed gases of a bottle whose closure is broken, when necessary, by a device which also conveys the flow into the check valve of the life-jackets.
  • the device is designed to be actuated only manually and by means of a lever, while other cases also allow the automatic intervention of a snap-action device which is activated by contact with water.
  • two versions of inflatable life-jacket are commercially available which differ only in the type of actuation, which is either manual or mixed, for the same inflation device. Fitting the inflation device to the valved support already fixed to the life-jacket, and the optional application of the automatic actuation unit to the device already equipped with a manual actuation system are operations which can be performed only along the assembly lines of said inflatable life-jackets.
  • valved device with automatic and/or manual actuation, for quickly inflating life-jackets or other items, characterized in that it comprises a main body having a flat base for fixing to the fabric of a life-jacket, said jacket being provided with a hole, a seat being provided at said hole for the sliding of first elements meant to tear the closure of a bottle of compressed air or gases and of second elements which are coaxial to said first elements and subsequently keep the life-jacket inflated.
  • the main body A of the device has a flat base 1 which is meant to be fixed around a hole of the life-jacket by heat-sealing or other suitable methods and perimetrically delimits the recess 2 into which the opening 3 leads.
  • the opening 3 is provided in the cylindrical seat 4 in the portion that acts as a seat for the check valve, i.e., proximate to the front end of the seat which, by means of a choke 5 with radial slits, is connected to a threaded seat 6 into which a bottle of air or compressed gases is to be screwed.
  • a slit 8 for a manual actuation lever L is also provided laterally and at the cylindrical seat 4 in the body A of the device, which is externally threaded at a rear end 7 in order to allow to screw thereon a cap B or a body M of a snap-action device.
  • the lever L is pivoted by the insertion of a pivot R in a suitable seat 9 of the body A.
  • the lever L is pivoted in R, can be activated by means of a cord and is almost entirely accommodated, when inactive, in the appropriately provided recess of the body A.
  • An axial hole 12 ( Figure 12) is connected to the transverse slit 11, and the rear stem of the plunger C enters said hole for coupling. This is done so that the metal lever L acts directly on the plunger C rather than on the plastic extension D which acts as a support and guiding element for the plunger.
  • Figure 3 shows the valve G and the gasket H in such a retracted position as to fully expose the opening 3, in practice this is not indispensable in order to achieve inflation of the life-jacket, since the gasket H provides a front seal and it therefore merely has to shift from its resting position to allow the flow to pass peripherally and in any case enter the opening 3.
  • the invention provides for the screwing of a body M of a snap-action device in the rear end 7 of the main body A instead of the cap B.
  • the device has a pusher N which is inserted in a helical spring O which acts between the flange 15 of the pusher and the flange 14 of a caliper P the jaws whereof, shaped so as to wedge into a groove 13 of the pusher N, keep the spring O compressed until they remain clamped by a ring Q which, being made of water-soluble or at least hygroscopic material, breaks quickly, decomposing or changing shape, when water flows in from the large hole 16 provided for this purpose on the bottom of the body M.
  • the pusher N Since the pusher N is retained by resting with an inclined or wedge-shaped portion against a corresponding portion of the jaws of the caliper P, which are fastened by a ring Q made of paper or other suitable material, the breakage of the ring and the tension of the spring O allow the pusher to move, spacing the jaws apart while the flange 14 of said caliper continues to rest against an internal abutment of the body M.
  • the pusher moves into abutment against the rear end of the body A and pushes axially, by means of the extension D, the plunger C, whose movement and related effects are identical to those which can otherwise be obtained by manually actuating the lever L, which instead has no effect in this circumstance.
