Definitions

  • the invention relates to an auxiliary system, in particular for use as an ice rescue system in ice rescue, according to the preamble of claim 1.
  • ice rescue without any aids is difficult and dangerous. Therefore, one uses, if possible, suitable rescue equipment.
  • Rescue equipment for ice rescue is basically all items that distribute the weight of the rescuer and the accident victim on the ice over a large area as possible and are able to bridge the distance from a safe place to the accident victim. Often rods, ladders and / or boards are used as aids.
  • auxiliary systems that are specially adapted to the requirements of ice rescue.
  • the international patent application WO 03/097438 A2 shows a motorized gliding boat for ice rescue. It has a catamaran-type main body of at least two parallel, spaced-apart, inflatable tubular bodies and a bottom arranged between the tubular bodies on which an air propeller propulsion is mounted.
  • Such special vehicles have a relatively complex structure and are therefore expensive, so that use is usually only in heavily trafficked waters in question.
  • the patent US 4,047,257 shows a life-saving device, which is constructed substantially like a roll-up snow fence. At one End is a base part for fixing on the shore of a body of water and attached to the other end made of rigid foam, fixed substantially cylindrical buoyant element, which serves as a support of the wound thereon fence and in the unrolled state as a rescue aid for the victim.
  • the patent US 4,990,114 shows an ice rescue system with a portable base member to which an inflatable tube assembly is attached, which has two mutually spaced tube sections to form a tubular web extending between a base member associated base portion and a head portion at the free end of the tube web.
  • a compressed gas system for filling the tube sections with pressurized gas has two compressed air cylinders attached to the base element, which are connected to compressed gas inlets located at the ends of the tube sections lying on the base element.
  • the base member has a bag-like container provided with handles, in the interior of which the tube assembly is stored folded when the auxiliary system is not needed. For use, the container is placed on the shore of the frozen water, aligned to the victim and opened.
  • the tube sections By filling the tube sections with compressed air, the tube sections quickly fill with air from the side of the base element, so that the tube path unfolds and its head section extends to the victim after completion of the filling.
  • Anchor lines are attached to the head section, which can be gripped by rescuers on shore to more precisely align the head section to the victim by pulling sideways. A rescuer can then use the exited hose path as an escape route to get to the victim and pull it out of the water. It is described that such auxiliary systems are available in different extended lengths, for example, 50 feet, 100 feet or 150 feet in inflated state.
  • the inflatable bridge can be rolled up or collapsed in the uninflated condition. It has two spaced-apart, inflatable tube sections which can be filled with compressed air from the base section lying in the rolled-up state in order to unroll the bridge. Between the tube sections relatively rigid, but elastic pressure distribution elements are arranged at certain intervals, which also serve as a spacer for the tube sections.
  • the invention provides an auxiliary system having the features of claim 1.
  • Advantageous developments are specified in the dependent claims. The wording of all claims is incorporated herein by reference.
  • An inventive auxiliary system of the generic type is characterized in that the tube section provided for forming a tubular web between a hose supply and the head section at the free end of the tubular web by a Hose guide device is guided with a tube cross-section of the hose section narrowing hose guide opening and that at least one leading into the interior of the hose section pressure fluid inlet is mounted in the region of the head portion.
  • the tube section is filled from the front end or from the head section of the tube web when pressure fluid is introduced through the pressure fluid inlet.
  • the introduced pressurized fluid then fills the tube section between the head section and the region of the tube guiding device, which narrows the tube cross section of the tube section in the region of the tube guide opening and, in the most favorable case, compresses or seals substantially fluid-tight.
  • a high fluid pressure can build up between the head section and the hose guide device in the hose section, so that the hose section is filled with pressure under pressure and stabilizes the extended length of the hose web as largely rigid elements.
  • the usable extension length of the tube web measured between the hose guide device or the hose guide opening and the head section can therefore be adjusted continuously to any desired values up to a maximum extension length by controlling the pressure fluid supply, wherein the hose section is filled with each extended length and thereby stabilizes the tube web.
  • the tube web may have a single tube section. Whose cross-section should be relatively flat in the expanded state, so have a relatively low height compared to the width, so that when expanding a tubular web is formed.
  • the height can e.g. a maximum of 20% of the width or a maximum of 10% of the width.
  • longitudinal and / or transverse webs or other connecting elements are stitched or incorporated in other ways, the opposite inner sides of the tubular casing connect to each other, so that an expansion in the direction of the webs is limited and no round cross section, but a flat cross-section results.
  • the hose assembly has at least two mutually spaced hose sections.
  • exactly two hose sections can be provided. These can limit the hose path laterally.
  • the individual tube sections can be constructed particularly simple and robust. They can each have a round cross-section when expanded.
  • the tube guiding means may comprise one or more fixed elements, e.g. in the form of rods or tubes which define the hose guide opening or contribute to the formation of a hose cross-section narrowing the hose guide opening.
  • the hose guide device has at least one pair of counter-rotating rollers that limit a serving as a hose guide opening gap for performing a hose section.
  • a substantial sealing of the hose section in the region (serving as hose guide opening) gap can be achieved by the normally rubberized inner surfaces of the hose section are pressed together by the rollers so that virtually no pressure fluid from the already expanded parts of the hose section to Hose inlet side can get on the side of the hose supply.
  • a hose section can thereby be filled particularly bulging and have a stabilizing effect on the hose assembly.
  • a fast extension of the tubular web to the desired length is facilitated by the rollers, since in the tubular web extension practically only rolling resistance can be overcome.
  • the rollers have parallel axes of rotation and are mounted on the base member.
  • a separate pair of counter-rotating rollers may be provided for each hose section.
  • a single pair of rollers or rollers may be sufficient to a wide Gap through which two (or more) hose sections can be passed at a mutual distance.
  • an adjustment means for changing the axial spacing of the rollers is provided.
  • an optimum gap width can be set for the phase of expansion of the hose arrangement, which offers a good compromise between sealing on the one hand and low rolling resistance on the other hand. If the hose assembly is to be retrieved after completion of an insert, so the center distance can be increased to allow easier withdrawal in the direction of hose supply.
  • the tube supply with one or more unexpanded, flat tube sections is preferably in a compact form to facilitate easy transport of long tube lengths.
  • hose sections for example, rolled up or many times folded in a hose package.
  • at least one hose supply roll for receiving the hose supply is provided on a hose inlet side of the hose guide device.
  • hose supply roll larger hose lengths can be stored without kinking and thus gently over long periods of time, so that they are always functional for use.
  • unexpanded tube sections can then be withdrawn from the tube supply roll through the extending tubular web and moved through the tubular guide opening.
  • a separate hose supply roll is preferably provided for each of the hose sections and the hose supply rollers are rotatably mounted on the base part in such a way that there is a gap between the hose supply rolls. This can essentially correspond to the distance which also exists in the extended tube web between the tube webs which stabilize and expand the tube web. This unwinding without unnecessary constraint on the tube sections and without the risk of tangling is possible.
  • the auxiliary system is operated with compressed gas, in particular with compressed air.
  • the pressurized fluid system is a pressurized gas system.
  • Expanded inflated tube sections can then be light and possibly buoyant, which can be particularly advantageous for use in the context of ice rescue or water rescue in general.
  • expansion by means of water pressure may be advantageous when the auxiliary device is mounted on a vehicle provided with water pumps, e.g. a fire engine or a vehicle of the Technical Relief Organization is attached.
  • a holder for one or more compressed gas cylinders may be provided on the head part, which are connected via a short line to the compressed gas connection and which then travel along with the head part when the tube web is extended.
  • the pressurized fluid system has at least one flexible pressurized fluid conduit leading from the base member to the pressurized fluid inlet at the head portion, the length of which may also increase in accordance with the length increasing upon deployment of the tubular conduit.
  • the source of pressurized fluid e.g., pressurized gas cylinder, compressor, water pump
  • a holder for receiving at least one exchangeable compressed gas container, in particular a compressed gas cylinder may be provided on the base part, so that the compressed gas cylinder can be transported together with the base part.
  • pressurized gas containers for example, compressed air cylinders are used, as they are also used in respiratory protection equipment of the fire department or divers. Such compressed air cylinders are regularly checked for reliability, so that the auxiliary system can be kept ready for use even after prolonged periods without use. Compressed air is particularly easy available, but in principle, other compressible gases or gas mixtures can be used.
  • the leading to the head portion hose sections in the region of the head portion by a suitable spacer in a suitable for use spaced apart may be to allow at least one rescuer to move on the tube web. Due to the fact that at each extended length leading from the hose guide device to the head section hose sections are filled and thus relatively stiff, can be dispensed with further devices for distance assurance between the hose sections, whereby the entire construction is relatively simple, inexpensive and reliable. The area between the tube sections can accordingly be free.
  • the hose arrangement has a flexible, preferably made of water-impermeable, tensile flat material manufactured surface element which extends between the tube sections and is attached to the tube sections.
  • the surface element spanned between the tube sections can serve as a bottom element of the tube web in order to allow safe movement along the tube web.
  • smaller ice-free areas along the tube web can be overcome with the help of the surface element without water gets between the tube sections.
  • the intended for locomotion top of the surface element may be equipped with anti-skid elements or designed to be non-slip, for example, by roughening.
  • the surface element may be a separate from the tube sections, elongated sheet-like element having on its longitudinal sides loops for passing the tube sections.
  • Inflated tube sections which have filled up between the head section and the tube guiding device and normally extend more or less parallel to each other at a mutual distance, can form a relatively stable and at the same time buoyant, if required, rail system.
  • this is exploited by providing a carriage movable along the tube web, which preferably has guide means for guiding the movement of the carriage at the tube sections.
  • the car can serve in an ice rescue device, for example, as a mobile pedestal for a couch, with the help of an accident victim can be driven from the head portion in the safe area in the vicinity of the base member.
  • One embodiment of the trolley is a trolley with wheels having a concave tread whose shape conforms to the shape of the top of expanded tube sections such that the wheels roll against lateral slipping on the tube sections.
  • guide devices separate from the wheels may be provided which reliably prevent the carriage from falling off the tubular web.
  • a carriage may also be provided if the hose assembly has only a single section of hose.
  • the head section can be made relatively stable and serve as a carrier of different functional elements.
  • at least one deflection roller is attached to the head section.
  • An elongate, flexible tension element for example a rope or a chain, can thus move from the base element to the deflection roller and be guided back toward the base member that an attached to the tension member object, such as a carriage, is movable by pulling on a portion of the tension element between the base member and head portion and in the reverse direction.
  • grip elements are very advantageous for the handling of the hose assembly and can also be easily grasped in the case of an accident victim to prevent submersion in the water.
  • auxiliary system Preferred embodiments of the auxiliary system are designed as a portable system that can be quickly carried, for example, by two average-weight people from one storage location to the job site. Also mobile variants are possible.
  • the base element may e.g. attached to a vehicle or formed by a part of the vehicle body. Integration into a rescue vehicle of the water protection or fire department is e.g. possible.
  • auxiliary system are optimized for use as ice rescue systems in ice rescue.
  • auxiliary systems of the types described herein are not limited to this type of use.
  • an auxiliary system for example, serve as a buoyant makeshift bridge to overcome not too broad waters.
  • the hoses should be sized accordingly large.
  • maximum extension lengths in the range of 20 to 60 meters, in particular in the range of 30 to 50 meters often useful and sufficient.
  • the maximum extension length of the tubular web can also be longer or shorter.
  • the width of the tubular web in the state of use can, for example, be around one meter in rescue systems. e.g. in the order of 0.5 m to 1.5 m, in particular in the range between 0.8 m and 1.2 m, to allow at least one rescuer to move on the tube web. For other applications, larger widths may be useful up to widths of several meters, which may allow use of the extended tube web as a makeshift road for motor vehicles.
