Definitions

the invention relates to a device for triggering an opening device, which is located together with a rescue device in a casing which is under vacuum and which opens the casing by pulling a first traction element enclosed by the casing, a second traction element extending outside the casing for transmitting a Tractive force is provided on the first tension element.
Rescue tools are often kept in a gas-tight, flexible envelope that is under vacuum because they take up so much less space.
the rescue device such as a parachute or an inflatable rescue device such as a life jacket, a life raft, a lifeboat or the like is compressed into a firm and very compact package by the external pressure on the casing.
the volume of the packaged rescue device can be reduced to a third of the volume that would be achieved without vacuum when packing carefully.
the advantage of the firm packaging is that individual packing layers, that is to say individual layers of the folded rescue device, cannot move relative to one another; the vacuum-packed package is rather very dimensionally stable.
inflatable rescue equipment such as life jackets, life rafts, lifeboats and the like are normally stored together with a pressurized gas bottle, so that they can be inflated quickly if necessary by actuating the valve of the pressurized gas bottle.
a pressurized gas bottle so that they can be inflated quickly if necessary by actuating the valve of the pressurized gas bottle.
the rescue device In order to reduce the packing volume, to achieve a stable packing position and to avoid cumbersome, regular checking procedures, it is known to provide the rescue device with the pressurized gas bottle with a casing under vacuum and to store it (DE-A-30 36 796). As long as this wrapping is still under vacuum, you can be sure that the rescue equipment is not damaged and that the compressed gas bottle still contains gas. If the rescue device has been damaged by an external pointed object, the casing is also damaged so that it loses its vacuum. If, on the other hand, compressed gas escapes from the compressed gas bottle, there can no longer be a vacuum in the casing. The absence of the vacuum can easily be determined, however, by the fact that the covering no longer tightly encloses the rescue device, but rather the package becomes soft and, depending on the extent of the leak, the covering loosely hangs from it sooner or later.
the rescue device If the rescue device is to be used, pull a pulling element.
the covering In the case of the parachute, the covering is torn open at a predetermined breaking point, so that the covering fills with air, the parachute takes on a looser pack and can therefore be pulled out of the covering. Of course, this pulling out can also take place automatically, for example when dropping loads from aircraft.
the valve of the compressed gas cylinder is actuated with the aid of a pulling element which can be gripped from outside the casing. When the rescue device is inflated, the envelope bursts as a result of the pressure and thus releases the rescue device.
the pulling element on which a person has to pull or on which a pull is exerted by an external device part normally consists of a rope, wire or the like of sufficient length.
This tension element is expediently provided outside the casing.
the first tension element is provided with a loop, within which an annular weld is carried out from two opposite walls of the casing.
the central area of this ring weld is removed and a loop of the second tension element is passed through it, so that the inside of the casing with the first tension element is separated from the outside world and the second outer tension element in a vacuum-tight manner.
an additional welding must take place, which not only requires additional work with a special ring-shaped or flat-shaped welding stamp when the rescue device is first packed, but also in all cases in which the device has to be repacked after damage to the casing or after a check .
the object of the invention is to provide an inflatable rescue device of the type mentioned with a cover, in which a vacuum-tight connection between the first (inner) and second (outer) pulling element can be produced in a simpler manner.
the solution according to the invention consists in that the first tension element extends in a tubular extension of the casing and is provided or connected with a thickening at its point remote from the opening device, the cross-sectional area of which is perpendicular to the direction of extension of the first tension element and is substantially larger than that of the first Tension element, and that around the first tension element between the opening device and thickening, including the tubular extension of the casing, the second tension element is placed with a loop, the cross-sectional area of which is larger than that of the first tension element and smaller than that of the thickening.
the first tension element is therefore arranged on a tubular extension of the casing, which can already be produced during the manufacture of the casing.
the first tension element has a thickening behind which the loop of the second tension element grips. Between the first and second tension element there is a part of the tubular extension of the casing; an additional weld does not have to be carried out for this. All that is required is a loop of the second tension element behind the thickening around the first tension element and secured, which can be done with a wire rope by a metal clip, with a plastic rope by sewing.
the first tension element can also be a rope or a wire rope.
the thickening of the first tension element can, for. B. be a knot. So that the thickening can easily be made large enough to ensure reliable functioning even when the loop of the second tension element is not too tight, the thickening can be a separate element with a circumferential groove into which a loop of the first tension element is inserted. This loop is to be secured in a similar way to the corresponding loop of the second tension element against unintentional opening.
this component can also be provided with bores for receiving the first tension element. It could also consist of two larger parts, which are held together by a screw, in which case a loop of the first tension element can be screwed tight between the two individual parts of the thickening. Provisions can also be made that more than one tension element can be connected to the thickening if the removal of the rescue device from the casing requires more than one such tension element.
the outer pulling element is always to be connected to the rescue device, it can be provided that the thickening is connected to the rescue device with a connecting line, the loop of the second pulling element also enclosing the connecting line.
the covering behind the thickening must be gathered up by the loop of the second tension element.
this gathering does not take place first through the outer traction element, but rather through an outer strapping or the like, which can be attached before the evacuation.
This outer constriction is provided between the opening device and the thickening around the first tension element.
This outer strapping advantageously consists of an adhesive tape. After evacuation, this gathering is fixed automatically by the vacuum. The adhesive tape only has an auxiliary function for the process of evacuation.
the folds of the gathering can z. B. are held together by a thread, a yarn or a push button which is guided through holes outside the weld.
the thread or the yarn can be dimensioned so that it tears easily when pulling on the second tension element (predetermined breaking yarn). Since this gathering only has to be fixed primarily during the evacuation and then fixes itself, the thread, the thread or the push button can also be removed afterwards.
the outer covering can be effectively secured against damage if the outer covering is surrounded by a hard foam jacket which, like the covering, flakes off even when the rescue device is inflated.
Fig. 1 an envelope 1 is shown, which has a tubular extension at 2.
a vacuum-tight, all-round weld seam 4 is provided in the vicinity of the edge region 3 of the casing 1.
the actuators for a valve 5 are introduced, namely two first or inner traction cables 6, which are looped around a thickening 7, hereinafter called loop holder, the loops being closed with the aid of metal clips 8 or the like.
a connecting line 9 is fastened in a similar manner around the loop holder 7 between the rescue device (not shown) and the loop holder 7.
the loop holder 7 consists of two parts that can be screwed together by a screw 10, so that the loops of the tension elements 6 and the connecting cable 9 can be made beforehand.
a plurality of holes 11 are provided, one above the other, through which a thread or a yarn 12 is drawn.
Fig. 2 it is shown how directly below the loop holder 7 the tubular extension 2 is gathered together by an adhesive tape 13 and fixed in this gathered position.
the tubular extension 2 can then be gathered in the area of the holes 11, this gathering 14 or its folds being secured by tightening and knotting the yarns 12.
the casing 1 can then be evacuated after it has been welded to the side from which the rescue device with the aforementioned devices was inserted.
FIG. 3 shows in particular the folds of the gathering 14, which are held together by the knotted yarns 12.
the second (outer) tension element 15 can then be placed around the first (inner) tension elements 6 in the region of the adhesive tape 13 with a loop 16, in which case the loop 16 can be secured against unintentional opening in the case of a plastic rope, for example by sewing 17 . If you pull the second pulling element 15, the wrapping film 1 does not need to be torn, since the predetermined breaking yarns 12 tear and thereby release the folds so that they can be stretched. The pulling force then only needs to open the valve 5, as a result of which the rescue device is inflated and as a result of which the previously vacuum-tight envelope 1 is destroyed only at this moment.
