Definitions

  • 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.
  • 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.
  • 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.
  • the aim of the invention is to make it easy for every skier to take advantage of a search and rescue system.
  • 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.
  • each person at risk Indicator contains a receiver tuned to the frequency of the search transmitter and a transmitter.
  • 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.
  • the indicator located at the skier is actively designed and that it forms a unit together with a ski pass.
  • 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.
  • 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.
  • 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.
  • the indicator 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.
  • FIG. 1 Another possibility is to attach a lanyard to the unit consisting of indicator 1 and ski pass 2 and use it as an antenna.
  • a lanyard shown partially in broken lines, designated by 9 and attached to the sheath 3.
  • 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.
  • 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.
  • the fourth side of the plastic cover is closed, preferably welded.
  • 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.
  • FIGS. 2a and 2b One way in which this can be done is shown in FIGS. 2a and 2b.
  • a switching element 18 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).
  • 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.
  • 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.
  • 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.
  • 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.
