Navigationsgeräte sind seit der Verfügbarkeit des GPS (Global Positioning System) , das auf dem Prinzip der Triangula- tion beruht, weit verbreitete Orientierungshilfen. Als Triangulationspunkte dienen beim GPS geostationäre Satelliten. Ortsbestimmungen auf der Erdoberfläche mittels GPS liefern heute zuverlässige Angaben sowohl in lateral-horizontaler als auch in vertikaler Richtung bis zu einem Fehler im Mil- limeter- bzw. Zentimeterbereich.Since the availability of the GPS (Global Positioning System), which is based on the principle of triangulation, navigation devices have been widely used as orientation aids. Geostationary satellites serve as triangulation points for the GPS. Location determinations on the surface of the earth using GPS today provide reliable information both in the lateral-horizontal and in the vertical direction up to an error in the millimeter or centimeter range.
Bekannt sind einerseits voluminöse Navigationssysteme in Automobilen, Schiffen, Flugzeugen und anderen Verkehrsmitteln mit genügend Tragkapazität und Raum für die Unterbringung dieser Systeme, die oft vom Anzeigegerät räumlich getrennte Empfangsteile und Energiespeicher umfassen. Andrerseits ermöglicht die fortschreitende Miniaturisierung in der Elektronik die Herstellung von tragbaren Navigationssystemen.On the one hand, voluminous navigation systems are known in automobiles, ships, airplanes and other means of transport with sufficient carrying capacity and space for accommodating these systems, which often include receiving parts and energy stores that are spatially separated from the display device. On the other hand, advancing miniaturization in electronics enables the manufacture of portable navigation systems.

Of course, athletes are understood to be people of both sexes.
Erfindungsgemäss wird die Aufgabe gelöst durch das Vorschlagen eines tragbaren Navigationsgerätes mit einem Bildschirm, einer GPS-Einheit, einer Logik, einer Bedienungseinrichtung, einem Datenspeicher, einer Energieversorgung und einem Ge- häuse, welches durch ein Befestigungsmittel zum Befestigen des Navigationsgerätes am Körper eines Sportlers gekennzeichnet ist. Weitere Ausbildungen und Ausführungsformen ergeben sich aus den abhängigen Ansprüchen.According to the invention, the object is achieved by proposing a portable navigation device with a screen, a GPS unit, a logic, an operating device, a data storage device, an energy supply and a housing, which is characterized by a fastening means for fastening the navigation device to the body of an athlete is. Further designs and embodiments result from the dependent claims.
Im Folgenden wird die Erfindung anhand von Zeichnungen, welche lediglich Beispiele darstellen und keinesfalls den Umfang der Erfindung einschränken sollen, dargestellt. Es zeigen:The invention is illustrated below with the aid of drawings, which merely represent examples and are in no way intended to limit the scope of the invention. Show it:
Fig. 1 eine Draufsicht auf den Bildschirm des Navigationsgerätes, gemass einer ersten Ausführungsform, z.B. für Skifahrer;Fig. 1 is a plan view of the screen of the navigation device, according to a first embodiment, e.g. for skiers;
Fig. 2 eine Draufsicht auf den Bildschirm des Navigations- gerätes, gemass einer zweiten Ausführungsform, z.B. für Schwimmer; Fig. 3 eine Seitenansicht des Navigationsgerätes, gemass einer ersten Ausführungsform.2 shows a top view of the screen of the navigation device, according to a second embodiment, for example for swimmers; Fig. 3 is a side view of the navigation device, according to a first embodiment.
Fig. 4 eine Seitenansicht des teilweise aufgeklappten Na- vigationsgerätes, gemass einer dritten Ausführungsform, z.B. für Gleitschirmflieger.4 is a side view of the partially opened navigation device, according to a third embodiment, e.g. for paragliders.
Fig. 1 zeigt eine Draufsicht auf den Bildschirm des Navigationsgerätes 1, gemass einer ersten Ausführungsform, z.B. für Skifahrer. Der Bildschirm 2 - vorzugsweise handelt es sich um einen hochauflösenden Schwarz/weiss- oder Farb- Bildschirm - nimmt einen grossen Teil der Oberfläche 3 des Navigationsgerätes ein. In den Seitenflächen 4 ist eine Bedienungseinrichtung 5 eingelassen, die vorzugsweise vier Ta- sten umfasst; es kann jedoch auch eine beliebige andere Anzahl von Tasten oder weiteren Bedienungselementen vorgesehen sein. Diese Bedienungseinrichtung 5 kann zur Veränderung der Anzeige auf dem Bildschirm bzw. zum Abrufen von Daten aus dem Datenspeicher und deren Anzeige verwendet werden. Es können aber auch Daten über die Bedienungseinrichtung 5 in das Navigationsgerät eingegeben und im Datenspeicher aufbewahrt werden. Für Sportarten wie z.B. Skifahren und Wandern ist es von Vorteil, wenn der Bildschirm 2 und die Bedienungseinrichtung 5 spritzwassergeschützt oder sogar wasser- dicht mit dem Navigationsgerät 1 verbunden sind. Mit dem Navigationsgerät verbunden - oder zumindest temporär verbindbar - ist ein Befestigungsmittel 6 in Form eines Bandes, eines Reifs oder eines anderen Bekleidungsstückes, wie z.B. Handschuhs, mittels welchem der Sportler - während der Aus- Übung seines Sportes - das Navigationsgerät am Körper, vorzugsweise am Arm, Kopf, Oberschenkel oder Rumpf tragen kann. Der Bildschirm 2 kann Daten von Gegebenheiten einer bestimmten geographischen Region in Form einer Karte anzeigen. Diese Daten, welche mittels einer Bedienungseinrichtung 5 aus dem Datenspeicher abgerufen werden, können beispielsweiseFig. 1 shows a plan view of the screen of the navigation device 1, according to a first embodiment, e.g. for skiers. The screen 2 - preferably a high-resolution black / white or color screen - occupies a large part of the surface 3 of the navigation device. An operating device 5 is embedded in the side surfaces 4, which preferably comprises four buttons; however, any other number of buttons or further operating elements can also be provided. This operating device 5 can be used to change the display on the screen or to call up data from the data memory and display them. However, data can also be entered into the navigation device via the operating device 5 and stored in the data memory. For sports such as Skiing and hiking is advantageous if the screen 2 and the operating device 5 are connected to the navigation device 1 in a splash-proof or even waterproof manner. Connected to the navigation device - or at least temporarily connectable - is a fastening means 6 in the form of a band, a hoop or another item of clothing, such as Glove, by means of which the athlete can wear the navigation device on the body, preferably on the arm, head, thigh or trunk, while practicing his sport. The screen 2 can display data from the conditions of a specific geographic region in the form of a map. These data, which are retrieved from the data memory by means of an operating device 5, can, for example
Skilifte 7, 8, 9, Skipisten 10, 11, Restaurants 12, Bahnhöfe 13 und Verkehrswege 14 umfassen. Zudem kann auf dem Bildschirm 2 auf spezielle Gefahren 15, wie Lawinen hingewiesen werden. Örtliche Vegetation und andere wichtige Hindernisse, wie Schluchten und Gewässer, können ebenfalls angezeigt wer- den. Vorteilhafterweise werden auch die Schwierigkeiten der verschiedenen Skipisten angegeben. Das Navigationsgerät eignet sich gleichermassen für den alpinen und nordischen Skisport. Über eine GPS-Einheit werden entsprechende Satelli- ten-Signa-le empfangen, von einer GPS-Logik verarbeitet und einer zentralen Rechnereinheit zugeleitet. Zum Anzeigen der geographischen Position des Navigationsgerätes entsprechend den GPS-Signalen, wird ein Cursor 17 oder Punkt auf dem Bildschirm 2 erzeugt. Mit der Bedienungseinrichtung 5 kann die Karte in gewünschtem Massstab und Ausschnitt auf dem Bildschirm 2 zur Anzeige gebracht werden. Das Navigationssystem 1 ist mit einer zentralen Energieversorgung versehen, welche vorzugsweise in Form von Akkumulatoren im selben Gehäuse wie das Navigationsgerät untergebracht ist. Die Daten der Gegebenheiten einer bestimmten geographischen Region und gegebenenfalls eine Benutzungserlaubnis für die örtlichenSki lifts 7, 8, 9, ski slopes 10, 11, restaurants 12, train stations 13 and traffic routes 14 include. In addition, special dangers 15, such as avalanches, can be indicated on the screen 2. Local vegetation and other important obstacles such as canyons and bodies of water can also be displayed. The difficulties of the various ski slopes are also advantageously indicated. The navigation device is equally suitable for alpine and Nordic skiing. Corresponding satellite signals are received via a GPS unit, processed by GPS logic and sent to a central computer unit. A cursor 17 or point is generated on the screen 2 to display the geographic position of the navigation device in accordance with the GPS signals. With the operating device 5, the map can be displayed on the screen 2 in the desired scale and detail. The navigation system 1 is provided with a central energy supply, which is preferably accommodated in the form of batteries in the same housing as the navigation device. The data of the circumstances of a specific geographical region and, if applicable, a permission to use the local one
Einrichtungen (z.B. Skipass) werden vorzugsweise berührungslos über ein ebenfalls eingebautes Datenempfangssystem zum Empfangen dieser Daten und zur Weitergabe in den Datenspeicher des Navigationsgerätes 1 übertragen. Die Datenübertra- gung kann z.B. mittels Infrarotstrahlen oder mittels Induktion ausgeführt werden und verläuft vorzugsweise sehr rasch, z.B. in wenigen Sekunden.Devices (e.g. ski pass) are preferably transmitted in a contactless manner via a likewise built-in data reception system for receiving this data and for forwarding it to the data memory of the navigation device 1. The data transfer can e.g. by means of infrared rays or by induction and is preferably very rapid, e.g. in a few seconds.
Ein wahlweise eingebauter Radiofrequenz-Transponder zum zen- tralen Erfassen der individuellen geographischen Position des Navigationsgerätes erlaubt es, den genauen Aufenthaltsort des Skisportlers über ein zentrales System festzustellen und den Sportler aufzufinden, falls er in eine Situation kommt, aus der er sich nicht selbst befreien oder in der er sich nicht bemerkbar machen kann. Lebensrettende Einsätze im Falle von Lawinenniedergängen, Nebel oder allenfalls abseits der Pisten erlittenen Knochenbrüchen können durch die Angabe des Aufenthaltsortes des Sportlers wesentlich vereinfacht und deren Erfolgsquote gesteigert werden. Unterstützt werden kann die Tätigkeit von Suchtrupps durch den wahlweisen Ein- bau eines Senders für Lawinensuchgeräte . Das Sendesignal kann wahlweise - zum Sparen von Energie bzw. als Stromsparschaltung - abgeschaltet werden. Vorzugsweise wird dann das Sendesignal für den eingebauten Radiofrequenz-Transponder bzw. für das Lawinensuchgerät - falls eine Quittierung nach einem frei wählbaren Zeitintervall ausfällt - automatisch aktiviert. Die Bedienungseinrichtung 5 weist mit Vorteil Bedienungselemente auf, die so gross gestaltet sind, dass sie mit Handschuhen leicht bedient werden können. Ein Klarsichtdeckel (nicht gezeigt) kann zum Schutz des Bildschirms und der Bedienungseinrichtung auf das Navigationsgerät aufgesetzt, aufgeklappt oder aufgeschoben werden.An optional built-in radio frequency transponder for central recording of the individual geographical position of the navigation device allows the exact location of the skier to be determined via a central system and the athlete to be found if he comes into a situation from which he cannot free himself or herself in which he cannot make itself felt. Life-saving missions in the event of avalanches, fog or possibly off-site Broken bones suffered on the slopes can be significantly simplified by specifying the location of the athlete and their success rate can be increased. The work of search teams can be supported by the optional installation of a transmitter for avalanche search devices. The transmission signal can optionally be switched off - to save energy or as a power saving circuit. The transmission signal for the built-in radio frequency transponder or for the avalanche search device is then preferably activated automatically if an acknowledgment fails after a freely selectable time interval. The operating device 5 advantageously has operating elements that are designed so large that they can be easily operated with gloves. A transparent cover (not shown) can be placed on the navigation device in order to protect the screen and the operating device, opened or slid on.
Wird das Navigationsgerät gemass einer zweiten Ausführungsform z.B. zum Schwimmen und Tauchen eingesetzt, werden an die wasserdichte Verbindung von Bildschirm und Bedienungseinrichtungen erhöhte Anforderungen gestellt: Vorzugsweise wird dann das gesamte Navigationsgerät wasserdicht bis auf eine Tauchtiefe von 100 m ausgelegt (vgl. Fig. 2). Das Navigationsgerät 1 wird in diesem Fall vorzugsweise quer getra- gen, womit der Bildschirm 2 beim Betrachten dem Sportler eine Längsseite zuwendet. Damit ein möglichst grosser Teil der Oberfläche 3 als Bildschirm verwendet werden kann, sind hier beispielsweise drei Elemente der Bedienungseinrichtung 5 als sogenannte „touch screen"-Felder ausgebildet, eine Folienta- statur wäre eine möglich Alternative. Auf dem Bildschirm ist ein elektronischer Kompass 18 eingeblendet. Angezeigt werden können unter anderem Häfen 19, Ortschaften 20 und Badestrände 21. Auf spezielle Gefahren 22, wie z.B. Riffe oder Stellen mit starker Strömung kann ebenfalls hingewiesen werden. Während die Navigation mittels GPS den Aufenthaltsort an der Wasseroberfläche - mittels Einblendung eines Cursors 17 lie- fert - geben wahlweise eingebaute Spezialgeräte wie Tiefenmesser, Thermometer oder Uhr die Tauchtiefe, die Wassertemperatur bzw. die Tauchzeit an. Ein vollständiger Tauchcomputer, wie er aus dem Stand der Technik bekannt ist, kann ebenfalls eingebaut und dessen Anzeigen mit denjenigen des Navigationsgerätes kombiniert werden, so dass z.B. der Restsauerstoff oder die Dekompressionszeit etc. zusätzlich zu den Daten der unmittelbaren Umgebung des Tauchers angezeigt werden können.If the navigation device is used in accordance with a second embodiment, for example for swimming and diving, increased demands are placed on the watertight connection of the screen and operating devices: the entire navigation device is then preferably designed to be watertight to a diving depth of 100 m (cf. FIG. 2). In this case, the navigation device 1 is preferably carried transversely, so that the screen 2 turns a long side toward the athlete when viewed. So that as large a part of the surface 3 as possible can be used as a screen, three elements of the operating device 5 are designed as so-called “touch screen” fields, for example, a membrane keyboard would be a possible alternative. An electronic compass 18 is shown on the screen Ports 19, towns 20 and bathing beaches 21 can be displayed, among other things. Special hazards 22, such as reefs or places with strong currents, can also be pointed out, while navigation using GPS indicates the location on the water surface by means of a cursor 17 - finished - optionally built-in special devices such as depth gauges, thermometers or clocks indicate the depth, the water temperature or the dive time. A complete dive computer, as is known from the prior art, can also be installed and its displays combined with those of the navigation device, so that, for example, the residual oxygen or the decompression time etc. can be displayed in addition to the data of the immediate environment of the diver.
