Abstract

The tester consists of several pressure reducers (1) connected in parallel, each having a different sampling pressure according to the tyre to be tested. The supply pressure is constant (2). Each reducer can be activated individually via a detector system (3). The selection is made with the help of a marking card (4) on which the desired tyre pressure is coded. When the air-pressure tube (5) is applied to the tyre valve, the tester can be started by inserting the coding card (4). The air pressure in the tyre is tested and corrected automatically via the pressure reducer in question.

Description

Bezeichnung: Automatisch arbeitendes ReifendruckprüfgerätDesignation: Automatically working tire pressure tester

Beschreibung: Die Erfindung bezieht sich auf ein ReifendruckprüfgerSt,das sein Einsatzgebiet in Tankstellen,insbesondere bei solchen mit Selbstbedienunq,hat.Description: The invention relates to a tire pressure tester St which its area of application in petrol stations, especially those with self-service.

Zum Service eines Fahrzeuges gehört die ständige Kontrolle des Reifenluftdruckes.Der richtige Reifendruck stellt ein Sicherheitsmerkmal dar,auf das der Autofahrer sein größtes Augenmerk legen sollte.Auch vermindert der korrekte Luftdruck das Abnutzen des Reifenbelages.The maintenance of a vehicle includes the constant control of the tire air pressure Proper tire pressure represents a safety feature that the motorist will be on The correct air pressure will also reduce wear and tear of the tire covering.

Die momentan an Tankstellen im Einsatz befindlichen Geräte für die Reifendruckkontrolle werden mittels zweier Ventile bedient, wobei der im Reifen vorherrschende Luftdruck über ein Manometer etappenweise kontrolliert werden muß,was für den Laien eine oft nicht leicht zu bewältigende Aufgabe ist.Dazu kommt noch,daß ein grosser Teil der Autofahrer den richtiqen Reifendruck seines Fahrzeuges nicht kennt.The devices currently in use at gas stations for the Tire pressure controls are operated by means of two valves, the one in the tire The prevailing air pressure must be checked in stages via a manometer, which is often a difficult task for the layman to accomplish a large number of drivers do not have the correct tire pressure in their vehicle knows.

Die Erfindung des automatisch arbeitenden Reifendruckprüfgerätes soll es auch dem technisch nichtvisierten Autofahrer ermöqlichen, sicher,einfach und genau den Reifendruck seines Fahrzeuges einzustellen,ohne daß er die Druckwerte kennen muß.The invention of the automatically operating tire pressure tester is intended make it possible for the technically non-targeted motorist, safely, easily and precisely adjust the tire pressure of his vehicle without having to read the pressure values must know.

Dieses Problem wird dadurch gelöst,daß das Reifendruckprüfgerät aus einer Anzahl von parallelgeschalteten Druckminderer besteht, wobei durch Aktivieren eines oder mehrerer Minderer der jeweils gewünschte Luftdruck zur Verfügung steht.Die Aktivierung erfolgt über eine Codekarte,die während des Uberprüfvorganges in einen dafür vorgesehenen Schlitz des Gerätes gedrückt wird.This problem is solved by turning the tire pressure tester off consists of a number of pressure reducers connected in parallel, whereby by activating the required air pressure is available to one or more reducers Activation takes place via a code card that is inserted into a the slot provided for this purpose on the device is pressed.

Ist die Karte nicht griffbereit,dann kann das gerät auch qegebenenfalls manuell über Tasten in Betrieb gesetzt werden.Für jeden üblichen Reifendruckwert ist eine Taste vorgesehen.If the card is not at hand, the device can q if necessary can be operated manually via buttons for every common tire pressure value a button is provided.

Die Karte kann sehr billig herqestellt werden,da sie aus normalem Plastik besteht.Für den unterschiedlichen Reifendruck vorne und hinten am Wagen wird nur eine Karte benötigt,da die dazu notwendigen Stanzungen jeweils einmal auf den zwei Längsseiten durchzuführen ist.The card can be manufactured very cheaply because it is made from normal Plastic is made for the different tire pressures on the front and back of the car only one card is required, as the necessary punchings are made once must be carried out on the two long sides.

Beispiel: Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.Example: An exemplary embodiment is shown in the drawing and is described in more detail below.

Figur 1 zeigt den grundsätzlichen Aufbau des erätes.Es besteht aus mehreren,parallelgeschalteten Druckminderer(l),wobei jeder über unterschiedlichen Entnahmedruck verfügt,entsprechend den zu prüfenden Reifen.Der Versorgungsdruck(2) ist konstant.Jeder Druckminderer kann einzeln über ein Abtastsystem(3) aktiviert werden,die Auswahl erfolgt über eine Markierungskarte(4),auf welcher der gewünschte Reifendruck codiert ist.Ist der Luftdruckschlauch(5) auf das Peifenventil aufgesetzt,so kann durch Einqabe der Codierungskarte(4) das Gerät in Betrieb gesetzt werden.Der Luftdruck im Reifen wird über den angesprochenen Druckminderer automatisch geprüft und gegebenenfalls korrigiert.Uter das Erreichen des gewünschten Luftdruckes optisch und akustisch informiert,beendet der Benutzer den Überprüfvorqang mit dem Herausnehmen der Karte.Figure 1 shows the basic structure of the erätes.Es consists of several pressure reducers (l) connected in parallel, each with a different Withdrawal pressure, according to the tires to be tested The supply pressure (2) is constant. Each pressure reducer can be activated individually via a scanning system (3) The selection is made via a marker card (4) on which the desired Tire pressure is coded. If the air pressure hose (5) is attached to the pressure valve, so the device can be put into operation by entering the coding card (4) The air pressure in the tire is automatically checked by the pressure reducer mentioned and corrected if necessary.Uter the achievement of the desired air pressure optically and informed acoustically, the user ends the verification process with the removal the map.

Figur 2 zeigt die in der Praxis zuverwendende Codekarte.Die Darstellung weist auf die Benutzung der beiden Seitenflächen hin,die entsprechend dem Luftdruck mit "Vorne" und "Hinten" beschriftet sind.Im Beispiel wird ein Luftdruck der Vorderräder mit 2,1 atü und der Hinterräder mit 2,3 atü angenommen.Je nachdem,welche der Kartenlängsseite in das Gerät gedrückt wird,steht einmal der richtige Luftdruck für das Vorderrad bzw.nach einer 180 Graddrehung um die Kartenlängsachse der hintere Reifendruck zur Verfügung.Figure 2 shows the code card to be used in practice. The representation indicates the use of the two side surfaces, which correspond to the air pressure are labeled with "Front" and "Rear". In the example, the air pressure of the front wheels assumed to be 2.1 atmospheres and the rear wheels with 2.3 atmospheres, depending on which side of the map is pressed into the device, the correct air pressure is once for the front wheel or after a 180 degree turn around the longitudinal axis of the map, the rear tire pressure for Disposal.

Figur 3 zeigt die Karte,wenn sie im Gerät steckt.Hinter der Karte sind Tasten angedeutet,die ein manuelles Bedienen ohne Codeträger erlauben.Die Karte in der gezeigten Position setzt gerade den Druckminderer für den gewünschten Luftdruck des Vorderrades in Betrieb.Figure 3 shows the card when it is inserted in the device, behind the card keys are indicated that allow manual operation without a code carrier. The card in the position shown, the pressure reducer is currently setting the desired air pressure of the front wheel in operation.
