Definitions

  • the invention relates to a protective and rescue device, in particular an avalanche rescue device, comprising a collapsible, lightweight casing for producing a buoyancy body that can be filled with ambient air, and a directly connected, collapsible support frame, which can be unfolded by means of compressed gas, for the unfolding of the casing, which also automatically functions as a check valve serving inlet valve for filling the shell with ambient air during the unfolding process of the scaffolding and has an arbitrarily operable outlet valve.
  • a protective and rescue device comprising a collapsible, lightweight casing for producing a buoyancy body that can be filled with ambient air, and a directly connected, collapsible support frame, which can be unfolded by means of compressed gas, for the unfolding of the casing, which also automatically functions as a check valve serving inlet valve for filling the shell with ambient air during the unfolding process of the scaffolding and has an arbitrarily operable outlet valve.
  • the casing and the support structure directly connected to it are designed such that after the support structure has been inflated, the buoyancy body assumes a spherical balloon shape, with the individual inflatable chambers forming the support structure being of the type of degrees of longitude distribute the balloon and are connected by the envelope material.
  • the spherical shape gives the advantage that the smallest possible surface has the largest possible volume, but this advantage is associated with a considerable disadvantage which can be extremely serious in the event of an emergency.
  • the scaffold is only inflated when the wearer of the protective device has already been caught by the avalanche, the case may arise that snow masses already lie on one side of the scaffold at the beginning of the deployment process of the scaffold, which can result in the case that the Tubular support tubes arranged in the manner of degrees of longitude bend inwards on the side where there is a corresponding snow pressure, even though they are filled with compressed gas, which results in a crescent-shaped buoyancy body instead of a balloon-like one, despite the inflated support tubes of the scaffolding.
  • the object of the invention is to provide a protective device of the type described in such a way that deformation of the supporting structure in the sense of a reduction in the volume of the buoyant body is avoided even under unfavorable circumstances and the possible volume of the buoyant body of the protective device is achieved due to the design.
  • the design of the scaffolding in the sense that it forms a buoyancy body with the casing in the inflated state, which has a substantially triangular or trochoidal shape in cross section, ensures that the scaffolding can buckle, as is possible with the balloon-like buoyancy body cannot occur here, since the support structure, even if it is briefly deformed by snow masses, always reforms into the triangular shape, while the balloon-like support structure, once it has buckled inwards, can no longer occur because the kinked position of part of the support hoses in turn results in a stable position, which is never the case with the triangular shape.
  • connections of the main sections are formed by sections of the flexible material which form the support frame or the shell and are free of pressurized gas.
  • two-part joint connections can of course also be used unless there is a leak in the buoyancy body.
  • each main section is designed as a single chamber which is elliptically shaped in cross section in the inflated state.
  • a more stable configuration of the main sections results in an advantageous manner in that the opposing chamber walls of each main section are connected to one another at mutually offset locations and at these locations have a much smaller distance from one another than the adjacent regions or are directly connected to one another. This creates a structure of an inflatable mattress.
  • each main section has at least two channels running in the longitudinal direction thereof over its entire length, which are connected to one another at intervals by transverse channels.
  • This embodiment is particularly suitable for the formation of a preferred embodiment of a protective and rescue device, which is characterized in that the buoyancy body formed from the three main sections is designed in total horseshoe-shaped and provided with fastening straps which secure the protective device to the body of the body Protective wearer allowed in such a way that the bent area in the neck and the two free legs rest on the chest of the wearer.
  • this protection and rescue device is not limited to use in the event of an avalanche, but can also be used, for example, for rescue at sea.
  • Figure 1 shows one half of a symmetrically constructed rescue device according to the invention in the operating position on the body of an accident victim in an avalanche.
  • the rescue device comprises a buoyancy body, denoted overall by 1, a belt device, denoted overall by 2, for fastening the buoyancy body to a person, and pressurized gas cylinders 3 for filling a support structure 4 of the buoyancy body, can be sucked into the ambient air by an automatically acting inlet valve 5 when the support structure 4 is inflated by means of gas from the pressurized gas cylinders to develop the same
  • the buoyancy body 1 comprises an outer shell 6, on the inside of which the support frame 4, which will be described in more detail below, is formed by an inner shell 6 'which is provided at least in the region of the support frame 4 in order to close the inflatable chambers together with the outer shell 6 shapes that form the support structure 4.
  • This buoyancy body 1 consists of 3 main sections 7, which are connected to one another via connections 8, which are formed by the outer shell 6 and the inner shell 6 ', and thus form the buoyancy body, which has a substantially triangular or trochoidal cross-sectional shape.
  • FIGS. 2 to 5 show various design options for the main sections of a buoyancy body and their assignment to form a buoyancy body.
  • FIG. 2 shows a main section for forming a buoyancy body according to FIG. 1.
  • each main section 7 has an outer casing 6 made of foldable material and molded on the underside of the casing in the longitudinal direction of the main section extending channels 9 and transverse channels 10, which connect the longitudinal channels 9 with each other and together with these form the support structure 4.
  • the longitudinal channels 9 are arranged on the side edges of each main section 7, the outer shell 6 and the inner shell 6 'provided for forming the channels being firmly connected to one another and on the outer sides of the channels the movable connections 8 for the connection of three Form main sections 7 to form a buoyancy body. Between the transverse channels 10, a trough is created for receiving the head of the victim.
  • the buoyancy body which is composed of three main sections, is essentially horseshoe-shaped and, with its curved part, surrounds the neck of the wearer of this rescue device, while the free ends rest on the wearer's chest, as is also the case with a life jacket.
  • FIG. 3 shows a further embodiment of a main section.
  • the two sleeves 6 and 6 ' are connected to one another at different points 11 offset from one another in such a way that they are at a smaller distance from one another than the adjacent inflated regions.
  • FIG. 4 shows a cross section through a buoyancy body formed from three such main sections 7 '.
  • a particularly simple embodiment of a buoyancy body is shown in FIG. 5.
  • the inflatable support structure consists of simple chambers, the two shells 6 and 6 'being welded together only at their lateral edges to form the film hinges 8.
  • pressurized gas is pressed from the bottles 3 into the support structure 4, which, starting from a folded state, forms the triangular shape of the buoyancy body, into the interior 12 of which ambient air flows in via the valve 5, which additionally serves to stabilize the buoyancy body and in the event of spillage via a mouthpiece 13, which, for example, has a valve known per se, as in the case of floating wings, in order to compress it of the mouthpiece with the teeth to be able to take out the air contained in the interior 12 as breathing air.
  • the inlet valve designated as a whole by 5, is described in more detail below with reference to FIGS. 6 to 9.
  • the inlet valve 5, which works as a non-return valve, has a chamber 14 incorporated in the shell 6, which is delimited by a wall 15 from the inside of the shell.
  • the wall 15 has openings 16, while the shell 6 is provided with openings 17 in the region of the chamber 14.
  • the chamber 14 communicates with the outside air through these openings 17 and the chamber 14 with the interior of the casing 6, that is to say with the interior 12 of the drive body 1, via the openings 16.
  • a valve body 18 is inserted, which has an elliptical shape, as can be seen from FIGS. 8 and 9.
  • a sealing rib 19 protruding inward into the chamber 14 is formed within the chamber 14 on the inside of the casing 6, and its course is adapted to the outer oval boundary of the valve body 18. This sealing rib is at a distance from the wall 15. All openings 17 in the casing 6 are located within the area delimited by the sealing rib 19.
  • the valve body 18 is designed as an oval, elliptical disk which is thickened in the center to form a hub 20.
  • valve body 18 When the valve body 18 is in its normal operating position according to FIG. 8, it lies with its outer area on the sealing rib 19, the two main axes of the ellipse of the valve body 18 and that of the elliptical sealing rib 19 coinciding.
  • the outer edge of the valve body 18 protrudes slightly beyond the sealing rib 19, as can be seen from FIGS. 7 and 8, in order to achieve a good sealing effect.
  • valve body 18 If a vacuum is created in the interior of the shell 6 by the inflation of the support structure 4, the valve body 18 is lifted off the sealing rib 19, as can be seen from FIG. 6. In this state, outside air can penetrate through the openings 17 into the chamber 14 and from here via the openings 16 into the interior 12 of the buoyancy body 1 and support it in its unfolded state, as can be seen from FIG. 1. If the pressure difference between the atmosphere and the interior 12 is equalized so that no more air flows into it, the valve body 18 rests on the sealing rib 19 due to its elastic design and thus prevents the escape of the ones located in the interior 12 of the buoyancy body 1 Air.
  • valve body 18 is rotated by means of the handle 24 about its central axis determined by the bearing pins 21 and 22 by 90 ° into the position shown in FIG. 9, whereby the two are moved by the valve body 18 and the sealing rib 19 are rotated by 90 ° certain ellipses. This creates at the ends of the long axis, the ellipse determined by the sealing rib 19, two areas 28 and 29 which are no longer covered by the valve body 18 and through which the air contained in the buoyancy body can escape.
  • the compressed gas from the scaffold 4 is by means of a Pressure bottles 3 arranged and not shown, drained manually operated two-way valve.
