Abstract
Description
"Geschwindigkeits- und/oder Streckenmeßvor- "Speed and / or distance measurement
richtung, insbesondere für SKi-Fahrer" Der Erfindung liegt die Aufgabe zugrunde, einen Geschwindigkeits- und/oder Streckenmesser zu schaffen, Diese Aufgabe wird erfindungsgemäß gelost durch einen in Bewegungsrichtung und in entgegengesetzter Richtung wirksamen Beschleunigungsmesser, eine Uhr, eine die Erdbeschleunigung erfassende Einheit und einen ttecnner, iler aus dcr Beschleunigung und der Zeit unter 13erück.sicntigung (ler t.rdbeschleunigung die Geschwindigkeit und/oder die zurückgelegte Strecke errechnet. direction, especially for skiers "The object of the invention is based on creating a speed and / or distance meter, this task is solved according to the invention by one in the direction of movement and in the opposite direction Direction effective accelerometer, a clock, one that records the acceleration of gravity Unit and a technician, iler from the acceleration and the time below the delay (The speed and / or the distance covered is calculated from the earth's acceleration.
Sinne sol.che Vorrichtung ist z.B. für Ski-Fahrer, Flugzeuge, Passagiere in Flugzeugen oder Zeigen und Raketen geeignet.The sense of such a device is e.g. for skiers, airplanes, passengers suitable in airplanes or pointing and missiles.
Vorzugsweise besteht der Beschleunigungsmesser aus einem Körper, der in Bewegungsrichtung und in entgegengesetzter richtung bewegbar gelagert ist, wobei insbesondere der K(rper federnd gelagert ist.Preferably, the accelerometer consists of a body that is mounted movably in the direction of movement and in the opposite direction, wherein in particular the body is resiliently mounted.
Die eingangs erwähnte Aufgabe wird ferner fLir einen sich längs einer Flache bewegenden Gegenstand Gelöst durch eine Strahlquelle insbes. Lichtquelle, die auf die Fliche einen Strahl wirft, eine Fotozelle od.dgl., die den reflektierten Strahl empfängt, und eine Einheit, die aus den Schwankungen der von der Fotozelle od.dgl. stammenden elektrischen Größe die Geschwindigkeit und/oder zurückgelegte Strecke bestimmt.The task mentioned at the beginning is also for you along a Flat moving object Solved by a beam source, especially a light source, which throws a beam on the fish, a photocell or the like. That reflected the Beam receives, and a unit resulting from the fluctuations of the photo cell or the like. originating electrical quantity the speed and / or covered Route determined.
Diese Vorrichtung ist im Gegensatz zu der zuerst genannten, die unabhängig von der Umgebung ist, nur anwendbar, wenn der Gegenstand sich längs einer Fläche bewegt; sie ist also z.B.This device, unlike the first mentioned, is independent of the environment is only applicable when the object is along a surface emotional; she is e.g.
für Ski-Fahrer geeignet.suitable for skiers.
Jan kann bereits mit einer Lichtschranke arbeiten, wenn der Untergrund eine (i.n Grenzen) stets gleichmässige Struktur hat, was beispielsweise bei einem über Schnee laufenden Ski der Fall ist.Jan can already work with a light barrier when the underground a (within limits) always has a uniform structure, which is for example a is the case with skis running over snow.
Eine Weiterentwicklung der Erfindung besteht darin, daß in Bewegungsrichtung hinter der ersten Strahlschranke eine zweite Strahlschranke angeordnet ist, deren auf der Fläche befindlicher bestrahlter Fleck in Bewegungsrichtung hinter dem bestrahlten lied: der ersten Strahlschranke liest sind von gleicher rorm wie dieser ist, und daß die elektrische Größe des Empfängers der zweiten Strahlschranke ebenfalls der Einheit zugeführt wird. Beide Empfänger liefern (quasi-) gleiche elektrische Größen, aus deren Phasenverschiebung man auf die Geschwindigkeit schliessen kann.A further development of the invention is that in the direction of movement a second beam barrier is arranged behind the first beam barrier, whose The irradiated spot located on the surface is behind the irradiated spot in the direction of movement song: the first beam barrier reads are of the same rorm as this one, and that the electrical size of the receiver of the second beam barrier is also the Unit is fed. Both receivers deliver (quasi) the same electrical quantities, from the phase shift of which one can infer the speed.
Um dem Verkanten eInes Skis Rechnung zu tragen, bei dem sich die Strahlschranke von der Unterlage entfernt, wird vorgeschlagen, daß in Bewegungsrichtung seitlich neben der ersten Strahlschranke eine zweite Strahischranke gleicher Art angeordiiet ist.In order to take account of the tilting of a ski in which the beam barrier removed from the base, it is suggested that laterally in the direction of movement a second beam barrier of the same type is arranged next to the first beam barrier is.
Weitere lpinzelheiten der Erfindung ergeben sich aus der Zeichnung. Darin zeigen: Fig. 1 einen Ski mit einem Teil der erfindungsgemässen Vorrichtung, Fig. 2 eine Ausführungsform eines Beschleunigungsmessers in Seitenansicht, Fig. 3 eine Draufsicht des in Fig. 2 dargestellten Beschleunigeungsmessers, Fig. 4 eine Einzelheit und Fig. 5 eine andere Ausführungsform.Further details of the invention emerge from the drawing. 1 shows a ski with part of the device according to the invention, FIG. 2 shows an embodiment of an accelerometer in side view, FIG. 3 is a top view of the accelerometer shown in FIG. 2, FIG. 4 is a Detail and FIG. 5 shows another embodiment.
In den Figuren 1 - 4 ist mit 1 ein Ski, mit 2 ein Gehuse, mit 3 ein in Ski-LinGsrichtung bewegbar gelagerter Körner und mit 4 Aufhängeeinheiten bezeichnet. Diese bestehen jeweils aus zwei Armen, die entweder starr sind und in den Gelenkpunkten federnd gelagert sind oder im unbelasteten Zustand eine Blattfeder (s. Fig. 4) bilden. Die Bewegungen des Körpers 3 bzw. die Kräfte, die er bei Geschwindigkeitsänderungen auszuüben in der Lage ist, werden elekt.risch abgenommen und über eine lösbare Verbindung ?, zweckmässigerweise über einen Schuh 6 des Ski-Fahrers zu einem Rechner geleitet.In FIGS. 1-4, 1 is a ski, 2 is a housing, 3 is a ski Grains mounted movably in the ski-line direction and labeled with 4 suspension units. These each consist of two arms that are either rigid and at the points of articulation are resiliently mounted or form a leaf spring in the unloaded state (see Fig. 4). The movements of the body 3 or the forces that it exerts when the speed changes is able to exercise, are removed electrically and via a detachable connection ?, expediently passed to a computer via a ski driver's shoe 6.
In Fig. 5 ist eine andere Ausführungsform der Erfindung dargestellt. In dem Ski 1 befindet sich eine Lichtschranke, bestehend aus einer Lichtquelle 6 und einer Fotozelle 7. l4it 8 ist eine durchsichtige, etwas zurückgesetzte Platte bezeichnet. Das Licht 9 wird am Untergrund reftektiert und gelangt in die Fotozelle 7.In Fig. 5, another embodiment of the invention is shown. A light barrier consisting of a light source 6 is located in the ski 1 and a photocell 7. l4it 8 is a transparent, slightly recessed plate designated. The light 9 is reflected on the ground and reaches the photocell 7th
