Definitions

• the invention relates to an inflatable life raft with at least one inflatable tube extending as a high-level floating body over the circumference of the life raft and with a bottom enclosed by the floating body and held by the tube for receiving at least one in the interior of the life raft enclosed by the tube and the bottom Person.
• a life raft of the aforementioned type is known for example from GB 1 266 753;
• the floating body of this life raft consists of two hoses arranged one above the other and connected to one another, which form a closed ring or a closed Nieleck and create an interior space intended for receiving a person to be rescued.
• the bottom of the life raft is attached to the gusset formed by the two tubes and connected to the tube or tubes.
• the known life raft has the disadvantage that the person to be rescued has to be moved over the circumferential, high-sided floating body, which is particularly difficult for unconscious and / or hypothermic people with restricted mobility and is difficult to achieve in some rescue situations.
• the invention is therefore based on the object of improving the introduction of people to be rescued into the interior formed by the life raft in a life raft with the features mentioned at the beginning.
• the invention provides in its basic concept that the life raft with its circumferential floating body forms the shape of a symmetrical trapezoid and is provided on its short base line by interrupting the high-sided floating body with a low-sided entry opening, the entry opening being defined by a between the ends of the legs of the high-sided float along the shorter base line of the trapezoidal support tube is supported with a height less than the height of the high-sided float.
• the advantage of the invention is that a person to be rescued can be "floated" into the interior of the life raft via the access opening formed in the life raft without it a high-sided floating body must be overcome.
• the support tube arranged in the area of the access opening serves to stabilize the shape of the life raft in this area, but only releases a level of lift that is so slight that it is easily overcome when the person to be rescued is pushed in and the corresponding movement is not opposed by any resistance.
• the trapezoidal shape of the liferaft takes into account the fact that the person to be rescued is first inserted with the feet into the liferaft through the entry opening, the upper body due to the trapezoidal shape due to the narrowing of the ends of the trapezoidal legs of the floating body due to the ends of the trapezoid legs on both sides the interior of the liferaft is fixed. The legs are placed on the high edge of the life raft so that the blood circulation towards the head is supported. Due to the trapezoidal shape of the life raft, there is enough space in the lower body of the person to be rescued to place additional rescue equipment, or an escort can be there.
• a container with compressed gas is held as the inflation medium; this is associated with the advantage that the container does not interfere with or obstruct the insertion of the person to be rescued.
• the container is packed together with the non-inflated life raft in a packing case and the container is connected to the packing case in addition to its holder on the floating body in such a way that after the deployment of the life raft from the packing case the packing case With remains attached to the liferaft and forms a capsizing protection hanging in the water; this advantageously prevents the packing envelope from floating off after the liferaft has deployed, so that the packing envelope can also be reused.
• the "floating" of the person to be rescued is facilitated according to one embodiment in that the ends of the ends of the trapezoidal leg of the trapezoidal leg of the tube forming the floating body are wedge-shaped in height such that the support tube is attached to the lower edge of the floating body and in turn is aligned with its lower edge with the lower edge of the float.
• the ends of the trapezoidal legs of the tube forming the floating body which point in the direction of the access opening, taper to a parallel course on their side surrounding the interior of the life raft and thus one form a rectangular entry area adjacent to the entry opening.
• a wedge-shaped cushion for supporting the head of a person to be rescued is arranged in the gusset formed by the support tube and the base.
• the corners of the floating body located between the two trapezoidal legs and the longer base line are chamfered.
• the bottom of the life raft is designed as a net bottom.
• additional aids and handling means are arranged on the life raft, such as a retaining line running around the circumference of the high-sided floating body, holding handles distributed on the top of the floating body over its circumference and / or arranged on the outside of the high-sided floating body Mesh existing bags.
• the handles can be designed so stable that they can serve as a connection to the carrying lines necessary for air pollution of the life raft, by means of which the life raft can be transported, including a person located therein, for example by helicopter.
• At least one capsize protection device is attached to the underside of the floating body.
• the high-sided floating body from a plurality of tubes which are connected to one another, so that this creates redundancy of the plurality of buoyancy bodies and thereby increases the safety of the life raft.
• FIG. 2 the life raft according to FIG. 1 in a front view
• Fig. 3 shows the liferaft according to Figure 1 in a side view.
• the life raft 10 shown in the drawing consists of a high-sided floating body 1 1 formed from a circumferential hose, which is shaped into a trapezoidal shape with a longer base line 12, a shorter base line 15 and trapezoidal legs 13 extending between them.
• the corners 14 located between the trapezoidal legs 13 and the longer base line 12 of the trapezoid are chamfered.
• An entry opening 19 is arranged in the area of the shorter base line 15, the high-sided floating body 1 1 not continuing in the area of the entry opening 19, but being supported by a support hose 17 connecting the ends 16 of the trapezoid legs 13 of the floating body 1 1.
• the support hose 17 is designed with a height less than the height of the high-sided floating body 11, the ends 16 of the ends of the trapezoidal legs 13 of the floating body 11 pointing in the direction of the entry opening 19 their height profile are wedge-shaped such that the support tube 17 is attached to the lower edge of the floating body 1 1 and in turn is aligned with its lower edge approximately with the lower edge of the floating body 1 1.
• the bottom 18 enclosed by the floating bodies 11 and the support tube 17 is designed as a mesh bottom.
• a container 23 is fixed in the region of the longer base line 12 on the underside of the floating body 11 by means of a holding tab 24, the container 23 containing a compressed gas as an inflation medium for inflating the life raft.
• an outer circumferential tether 26 made of mesh material for storing further life-saving means and on the top of the floating body 1 1 handholds 21 are attached, which can also be used to connect carrying lines by means of which the life-raft, possibly including a person inside is portable.
• the non-inflated liferaft 10 including the container 23 is housed in a packaging sleeve 25.
• the container 23 defined by means of the retaining tab 24 on the floating body 11 is additionally connected in a suitable manner to the packing sleeve 25, so that after the deployment raft 10 has been unfolded from the packing sleeve 25, the packing sleeve 25 remains connected to the life raft 10 and an additional, capsize protection hanging in the water.
• the packing envelope 25 is provided with a flap 29 in the area of the bottle holder, a valve 30 being accessible via the opened flap 29, by means of which the container 23 is opened and thus the life raft is inflated.
• the life raft 10 unfolds from the packing envelope 25 by tearing open closures of the packing envelope 25, for example in the form of Velcro closures.
• the person to be rescued is first put into the access opening 19 with the feet and pushed over the support tube 17 into the interior of the life raft 10, the legs being supported on the high-sided floating body 11 and the upper body aligned in the boarding area 20 and the head being supported on the cushion (not shown) provided on the support tube 17.
• the liferaft 10 can then be moved in the water via the tether 26 attached to it and the grab handles 21.
