Description

Die Erfindung bezieht sich auf einen Indikator zum Wieder­auffinden von durch Lawinen verschütteten Skifahrern mit Hilfe eines Such- und Rettungssystems, das mit Sendern und Empfängern arbeitet.The invention relates to an indicator for the retrieval of skiers buried by avalanches with the aid of a search and rescue system that works with transmitters and receivers.

Der Skisport ist zu einem Breitensport mit immer noch steigender Tendenz geworden. Vorhandene Skigebiete sind vielfach sehr groß. Sie dehnen sich wegen der Zunahme des Skisports aus. Auch vollständig neue Skigebiete werden immer noch erschlossen.Skiing has become a popular sport with an increasing tendency. Existing ski areas are often very large. They are expanding due to the increase in skiing. Completely new ski areas are still being developed.

Die Gefahr, daß Skifahrer Opfer von Lawinenunglücken werden, nimmt deshalb zu, zumal auch die Risikobereitschaft der Skifahrer zunimmt. Vorgegebene Pisten werden vielfach ver­lassen, um in den Genuß des Tiefschneefahrens zu kommen. In derartigen Gebieten herrscht häufig eine erhöhte Lawinen­gefahr. Ein schnellesAuffinden verunglückter Skifahrer ist deshalb eine Forderung, die immer dringender wird und die auch im Interesse der Betreiber der Skigebiete liegt. Die bisher bekannt gewordenen technischen Hilfsmittel haben diese Forderung nicht in befriedigender Weise erfüllen können, ins­ besondere nicht unter dem Gesichtspunkt der bereits er­wähnten Tatsache, daß der Skisport zu einem umfassenden Breitensport geworden ist.The risk of skiers becoming victims of avalanche accidents is therefore increasing, especially as skiers are more willing to take risks. Specified slopes are often left to enjoy deep snow skiing. There is often an increased avalanche risk in such areas. Finding skiers who have had an accident quickly is therefore a requirement that is becoming increasingly urgent and that is also in the interests of the operators of the ski areas. The previously known technical aids have not been able to meet this requirement satisfactorily especially not from the point of view of the fact that skiing has become a comprehensive popular sport.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zu­grunde, einen Indikator der eingangs genannten Art zu schaffen, welcher das Wiederauffinden verschütteter Ski­fahrer schnell und mit hoher Sicherheit gewährleistet. Außerdem soll durch die Erfindung erreicht werden, daß jedem Skifahrer in einfacher Weise die Möglichkeit geboten wird, die Vorteile eines Such- und Rettungssystemes zu nutzen.The object of the present invention is therefore to create an indicator of the type mentioned at the outset, which ensures that buried skiers can be found quickly and with a high level of safety. In addition, the aim of the invention is to make it easy for every skier to take advantage of a search and rescue system.

Mit Sendern und Empfängern arbeitende Such- und Rettungs­systeme sind an sich bekannt. Diese umfassen üblicherweise ein bei einer Suchmannschaft oder Rettungsorganisation be­findliches Peil- und Suchgerät, das mit einem Sender und einem Empfänger ausgerüstet ist. Die Energieversorgung dieses Ge­rätes ist nicht problematisch, da es entweder vom Netz ge­speist werden kann oder nur im Zuge von Rettungsaktionen zum Einsatz kommt. Vor jedem Einsatz können die im Gerät be­findlichen Batterien erneuert werden.Search and rescue systems working with transmitters and receivers are known per se. These usually include a direction finder and search device located at a search team or rescue organization, which is equipped with a transmitter and a receiver. The energy supply of this device is not problematic, since it can either be powered by the network or is only used in the course of rescue operations. The batteries in the device can be replaced before each use.

Bei den gefährdeten Personen befindet sich jeweils ein Indikator, der einen auf die Frequenz des Suchsenders eingestellten Empfänger sowie einen Sender enthält. Kommt es zu einem Notfall, dann werden mit Hilfe des Suchgerätes Signale ausgestrahlt. Wird ein solches Signal vom Empfänger des Indikators empfangen, dann schaltet dieser den Indi­kator-Sender ein. Die Signale des Senders werden vom Empfänger des Suchgerätes empfangen. Mit Hilfe dieser Sig­nale kann die Ortung der Verunglückten vorgenommen werden.There is one for each person at risk Indicator that contains a receiver tuned to the frequency of the search transmitter and a transmitter. In the event of an emergency, signals are transmitted using the search device. If such a signal is received by the receiver of the indicator, it switches on the indicator transmitter. The signals from the transmitter are received by the receiver of the search device. These signals can be used to locate the casualties.

Ein grundsätzliches Problem besteht in Bezug auf die Ener­gieversorgung der Indikatoren (vgl. die CH-PS 514 897 und die DE-OS 25 45 066) da diese für die Erzielung ausreichen­der Sende-Reichweiten mit einer eigenen Stromversorgung, z.B. einer Batterie, ausgerüstet sein müssen (aktiver Betrieb des Indikators). Eine ständige Einschaltung des Indikators führt zu einem schnellen Verbrauch der Batterie, so daß der Indikator seine Funktion nicht mehr erfüllen kann. Ist der Indikator von Hand ein- und abschaltbar, dann besteht die Gefahr, daß das Einschalten vergessen wird. Um diese Prob­leme zu lösen, ist vorgeschlagen worden, aufwendige Batte­rien in der Sohle des Skistiefels unterzubringen (vgl. die DE-PSen 25 25 444, 24 37 981 und komplizierte Akku-Lade­systeme im Bereich von Aufenthaltsplätzen gefährdeter Per­ sonen vorzusehen (DE-PS 31 09 283). Für den Massen-­Skisport sind solche Systeme wegen ihrer Kompliziert­heit und wegen ihrer hohen Kosten nicht einsetzbar. Sie haben sich deshalb auf dem Markt nicht durchsetzen kön­nen. Es sind zwar passiv betriebene Indikatoren, d.h. Indikatoren ohne eigene Energiequelle, bekannt (vgl. die DE-PS 23 52 807 sowie die DE-OSen 24 37 464, 32 11 381); diese sind aber für das Wiederauffinden von durch Lawinen verschütteten Skifahrern ungeeignet, da die Sender solcher Indikatoren nur sehr kurze Reichweiten haben.There is a fundamental problem with regard to the energy supply of the indicators (cf. CH-PS 514 897 and DE-OS 25 45 066) since these have to be equipped with their own power supply, for example a battery, in order to achieve sufficient transmission ranges (active operation of the indicator). Constantly switching on the indicator leads to rapid battery drain so that the indicator can no longer perform its function. If the indicator can be switched on and off manually, there is a risk that the switch-on will be forgotten. In order to solve these problems, it has been proposed to accommodate expensive batteries in the sole of the ski boot (cf. DE-PSen 25 25 444, 24 37 981 and complicated battery charging systems in the area of people at risk of staying to be provided (DE-PS 31 09 283). Such systems cannot be used for mass skiing because of their complexity and their high costs. Therefore, they have not been able to assert themselves on the market. Passively operated indicators, ie indicators without their own energy source, are known (cf. DE-PS 23 52 807 and DE-OSen 24 37 464, 32 11 381); however, these are unsuitable for the retrieval of skiers buried by avalanches, since the transmitters of such indicators have very short ranges.

Um die gestelle Aufgabe zu lösen, wird vorgeschlagen, daß der beim Skifahrer befindliche Indikator aktiv ausgebildet ist und daß er gemeinsam mit einem Skipass eine Einheit bildet.In order to solve the problem presented, it is proposed that the indicator located at the skier is actively designed and that it forms a unit together with a ski pass.

Skipässe werden in Liftkartenverkaufsstellen ausgestellt und berechtigen einen Skifahrer, die Liftsysteme eines Skigebietes zu benutzen. Ihre Gültigkeitsdauer ist be­schränkt, üblicherweise auf die Zeit eines Skiurlaubs, also beispielsweise ein oder zwei Wochen.Ski passes are issued at lift ticket sales points and entitle a skier to use the lift systems of a ski area. Their period of validity is limited, usually to the time of a skiing holiday, for example one or two weeks.

Das Zusammenfügen des Indikators mit einem Skipass zu einer Einheit bietet damit die Möglichkeit, jeden Ski­fahrer eines Skigebietes, dem ein Skipass ausgestellt wird, gleichzeitig mit einem Indikator auszurüsten. Hohe Anforde­rungen an die Aufrechterhaltung der Ladung der Batterien müssen nicht mehr gestellt werden da sie lediglich für die Gültigkeitsdauer des Skipasses benötigt werden. Die Angabe der Gültigkeitsdauer auf dem Skipass erlaubt es, das Alter der in der Kombination aus Indikator und Skipass befindlichen Batterie zu überwachen, so daß die Gefahr der Verwendung alter und damit schwacher Batterien nicht besteht.Combining the indicator with a ski pass to form a unit thus offers the possibility of equipping every skier in a ski area to whom a ski pass is issued with an indicator at the same time. High requirements for maintaining the charge of the batteries no longer have to be set because they are only required for the duration of the ski pass. Specifying the period of validity on the ski pass makes it possible to monitor the age of the battery in the combination of indicator and ski pass, so that there is no risk of using old and therefore weak batteries.

Der besondere Vorteil der Erfindung liegt darin, daß die vorgeschlagene Kombination eines Indikators mit einem Ski­pass das Problem löst, wie eine große Menge von Skifahrern mit einem Indikator ausgerüstet werden kann, so daß jeder der Skifahrer an dem Nutzen eines vorhandenen Such- und Rettungssystems teilhaben kann. Es kann ihm beispielsweise überlassen werden, ob er sich einen Skipass ohne oder mit Indikator kauft. Zu einer Zeit erhöhter Lawinengefahr be­steht die vorteilhafte Möglichkeit, ausschließlich Skipässe mit Indikator zu verkaufen, so daß der Betreiber eines Skigebietes besser in der Lage ist, seiner Verantwortung für die Sicherheit der Skifahrer nachzukommen.The particular advantage of the invention is that the proposed combination of an indicator with a ski pass solves the problem of how a large number of skiers can be equipped with an indicator so that each of the skiers can benefit from an existing search and rescue system . It can be left to him, for example, to buy a ski pass with or without an indicator. At a time when there is an increased risk of avalanches, there is the advantageous possibility of only selling ski passes with an indicator, so that the operator of a Ski resort is better able to assume its responsibility for the safety of skiers.

Weitere Vorteile und Einzelheiten der Erfindung sollen anhand der Figuren 1 und 2 erläutert werden. Es zeigen:

  • Figur 1 eine Ansicht der erfindungsgemäßen Kombination eines Skipasses mit einem (schematisch ange­deuteten) Indikator und
  • Figuren 2 a und 2 b einen schematischen Teilschnitt durch den Gegenstand nach Figur 1 im Bereich der Batterie.
Further advantages and details of the invention will be explained with reference to FIGS. 1 and 2. Show it:
  • Figure 1 is a view of the combination of a ski pass according to the invention with a (schematically indicated) indicator and
  • 2a and 2b show a schematic partial section through the object according to FIG. 1 in the region of the battery.

Die Figur 1 läßt erkennen, daß der Indikator 1 und ein Ski­pass 2 gemeinsam in einer Kunststoffhülle 3 untergebracht sind. Der Indikator 1 umfaßt den Empfänger 4, den Sender 5 und die Energiequelle 6, eine Batterie. Die für den Betrieb von Sender 4 und Empfänger 5 erforderliche Antenne ist als Drahtschleife 7 ausgebildet und erstreckt sich etwa parallel zum verschweißten Rand 8 der Kunststoffhülle 3.1 shows that the indicator 1 and a ski pass 2 are housed together in a plastic cover 3. The indicator 1 comprises the receiver 4, the transmitter 5 and the energy source 6, a battery. The antenna required for the operation of transmitter 4 and receiver 5 is designed as a wire loop 7 and extends approximately parallel to the welded edge 8 of the plastic sleeve 3.

Eine andere Möglichkeit besteht darin, eine Umhängeschnur an der aus Indikator 1 und Skipass 2 bestehenden Einheit zu befestigen und diese als Antenne zu verwenden. Diese Alternative ist durch eine teilweise gestrichelt darge­stellte, mit 9 bezeichnete und an der Hülle 3 befestigte Umhängeschnur in Figur 1 angedeutet.Another possibility is to attach a lanyard to the unit consisting of indicator 1 and ski pass 2 and use it as an antenna. This alternative is indicated in FIG. 1 by a lanyard shown partially in broken lines, designated by 9 and attached to the sheath 3.

Der beim Ausführungsbeispiel dargestellte Skipass 2 umfaßt mehrere Felder, in denen ein Lichtbild 11, eine Beschriftung 12, die Gültigkeitsdauer 13 und eine Codierung 14 unterge­bracht werden können. Die Codierung 14 ist von Kontrollauto­maten lesbar, die im Zugangsbereich eines Lifts angeordnet sein können und beispielsweise der Öffnung eines Drehkreuzes dienen. Mit 15 ist eine Öse bezeichnet, mit deren Hilfe die aus Indikator 1 und Skipass 2 bestehende Einheit, beispiels­weise an der Kleidung des Skifahrers, befestigt werden kann, wenn eine als Umhängeschnur 9 ausgebildete Antenne nicht vorhanden ist.The ski pass 2 shown in the exemplary embodiment comprises several fields in which a photo 11, a label 12, the validity period 13 and a code 14 can be accommodated. The coding 14 can be read by automatic control devices, which can be arranged in the access area of a lift and serve, for example, to open a turnstile. 15 denotes an eyelet, with the aid of which the unit consisting of indicator 1 and ski pass 2 can be attached, for example to the skier's clothing, if an antenna designed as a neck strap 9 is not present.

Die in Figur 1 dargestellte Einheit wird beispielsweise in der Liftkartenverkaufsstelle zusammengefügt, nachdem der Skipass mit Lichtbild, Gültigkeitsdatum und Codestreifen versehen worden ist. Zweckmäßig wird eine dreiseitig ge­ schlossene Kunststoffhülle verwendet, in der sich der Indikator 1 bereits befindet. Der Skipass 2 wird an­schließend eingeschoben. Abschließend wird die vierte Seite der Kunststoffhülle verschlossen, vorzugsweise ver­schweißt.The unit shown in FIG. 1 is assembled, for example, in the lift ticket office after the ski pass has been provided with a photograph, expiry date and code strip. A three-sided is expedient closed plastic cover used, in which the indicator 1 is already. The ski pass 2 is then inserted. Finally, the fourth side of the plastic cover is closed, preferably welded.

Erfindungsgemäß ist der Indikator 1 aktiv ausgebildet, d.h. während der Benutzung durch den Skifahrer ist der Sender 4 dauernd empfangsbereit. Empfängt er ein Signal vom zentralen Peil- und Suchgerät, dann schaltet er über die Leitung 16 den Schalter 17 ein, der den Sender 5 in Betrieb setzt. Diese Signale können vom zentralen Suchgerät empfangen und registriert werden.According to the invention, the indicator 1 is active, i.e. while the skier is using the transmitter 4 is constantly ready to receive. If it receives a signal from the central direction finder and search device, it switches on switch 17 via line 16, which switches transmitter 5 into operation. These signals can be received and registered by the central search device.

Vor dem Verschweißen der Hülle 3 ist es deshalb erforder­lich, den Sender 4 mit der Stromversorgung, der Batterie 6, zu verbinden. Eine Möglichkeit, wie dieses geschehen kann, ist in den Figuren 2 a und 2 b dargestellt. Der Batterie 6, deren einer Pol mit dem Empfänger 4 und - über den Schalter 17 - mit dem Sender 5 verbunden ist, ist ein Schaltglied 18 zugeordnet, das nach Art einer Heftzwecke gestaltet ist. Durch Druck - z.B. während des Verschweißens von einer Rolle ausgeübt - dringt der Stift dieses Schaltgliedes in die Batterie 6 ein und stellt einen Kontakt mit dem anderen Pol der Batterie 6 her (Figur 2 b). Gleichzeitig werden Kontakte zwischen dem Schaltglied 18 und Versorgungs­leitungen geschlossen, die zum Empfänger 4 und zum Sender 5 führen. Vorrichtungen, die dem gleichen Zweck dienen, sind ebenfalls bekannt und können verwendet werden. Ein be­kanntes Beispiel besteht aus federnd anliegenden Kontakten, zwischen denen sich, solange der Empfänger abgeschaltet sein soll, ein Materialstreifen aus isolierendem Werkstoff befindet. Dieser Streifen wird zur Einschaltung des Empfängers 4 entfernt.Before welding the casing 3, it is therefore necessary to connect the transmitter 4 to the power supply, the battery 6. One way in which this can be done is shown in FIGS. 2a and 2b. The battery 6, one pole of which is connected to the receiver 4 and - via the switch 17 - to the transmitter 5, is assigned a switching element 18 which is designed in the manner of a tack. By pressure - exerted by a roller during welding, for example - the pin of this switching element penetrates into the battery 6 and makes contact with the other Pole of the battery 6 ago (Figure 2 b). At the same time, contacts between the switching element 18 and supply lines are closed, which lead to the receiver 4 and the transmitter 5. Devices serving the same purpose are also known and can be used. A known example consists of resilient contacts, between which, as long as the receiver is to be switched off, there is a strip of material made of insulating material. This strip is removed to switch on the receiver 4.

Nach dem Einschalten des Empfängers 4 wird zweckmäßig ein Funktionstest durchgeführt, der sich auf die Batterie­ladung sowie auf das Ein- und Ausschalten des Notfallsenders über den Indikatorenempfänger beziehen kann. Das letztere ge­schieht durch Einwirkung der Suchfrequenz auf den Indikator­empfänger, um die Sendefähigkeit des Indikatorsenders fest­zustellen. Ein derartiger Funktionstest muß in einem ge­kapselten Gerät durchgeführt werden, damit in der Nähe be­findliche Indikatorenempfänger und -sender nicht aktiviert werden.After the receiver 4 has been switched on, a functional test is expediently carried out, which can relate to the battery charge and to the switching on and off of the emergency transmitter via the indicator receiver. The latter happens through the action of the search frequency on the indicator receiver in order to determine the transmission capability of the indicator transmitter. Such a function test must be carried out in an encapsulated device so that nearby indicator receivers and transmitters are not activated.

Die Kapazität der Energiequelle 6 sollte der Gültigkeits­dauer des zugehörigen Skipasses angepasst sein, wobei zu­ sätzlich berücksichtigt werden sollte, daß der Sender 5 ca. 6 bis 8 Stunden seine Antwortsignale aussenden kann. Zweckmäßig ist die aus Indikator 1 und Skipass 2 bestehende Einheit als Wegwerfteil ausgebildet, so daß Fehlfunktionen durch falsche Handhabung, Verwendung schwacher Batterien und dgl. ausgeschlossen sind. Aus Gründen des Umwelt­schutzes sollte die erfindungsgemäße Einheit nach Ablauf der Gültigkeitsdauer von der Kartenverkaufsstelle einge­sammelt und vernichtet werden. Mit Hilfe einer angemessenen Pfandgebühr kann dieses Ziel erreicht werden.The capacity of the energy source 6 should be adapted to the validity period of the associated ski pass, whereby to It should also be taken into account that the transmitter 5 can send out its response signals for about 6 to 8 hours. The unit consisting of indicator 1 and ski pass 2 is expediently designed as a disposable part, so that malfunctions due to incorrect handling, use of weak batteries and the like are excluded. For reasons of environmental protection, the unit according to the invention should be collected and destroyed by the ticket office after the period of validity has expired. This goal can be achieved with the help of a reasonable deposit fee.
