Abstract

The interlock system is designed to prevent misuse of self-service coin-operated units, where a coin is fed in by being attached to a piece of string. In such instances, the coin is allowed to fall past the checking station and is manipulated to cause release of the dispensing station. The coin (M) is attached to the string or thread (F) by an adhesive. When inserted into the slot the coin passes down a guideway. Located within the guideway is an interlock consisting of a large coil spring (1) and a second smaller coil spring (3). The two springs are counter wound and the thread in passing becomes securely held.

Description

Fadenmünzenfänger für Selbstkassierer Thread coin catcher for self-checkers

Die Erfindung betrifft einen Fadenmünzenfänger für Selbstkassierer nach dem Oberbegriff des Anspruchs 1.The invention relates to a coin catcher for self-checkers according to the preamble of claim 1.

Ein derartiger Fadenmünzenfänger ist aus dem DE-GM 72 08 409 bekannt. Bei dieser Anordnung ist der Einlaufkanal so gestaltet, daß eine Münze ihre Laufrichtung an einer bestimmten Stelle um fast 1800 ändert. Am Innenbogen dieser Biegung des Einlaufkanals ist die Kanalwand geschlitzt, so daß der Faden einer an einem solchen befestigten Münze in diesen Schlitz gleitet, sobald die Münze unterhalb der Kanalbiegung angelangt ist Damit ist das Zurückziehen der Fadenmünze unmöglich gemacht. Um die Sicherheit weiter zu erhöhen, ist bei der genannten Anordnungeine gewendelte Drahtfeder so angebracht, daß sie den geschlitzten Bereich des Innenbogens des Einlaufkanals durchquert. Dadurch verfängt sich der Faden im Schlitz noch zusätzlich in der Feder. Zwar erscheint es bei dieser Konstruktion ausgeschlossem, daß eine Fadenmünze wieder aus dem Selbstkassierer herausgezogen werden kann, doch ist es immer noch möglich, die Münze durch den Munzprüfer bis in die Kassiereinrichtung gleiten zu lassen und letzterer den Einwurf mehrerer Münzen durch Auf- und Abbewegen der Münze vorzutäuschen.Such a thread coin catcher is known from DE-GM 72 08 409. In this arrangement, the inlet channel is designed so that a coin its direction of travel changes at one point by almost 1800. At the inner curve of this bend of the Inlet channel, the channel wall is slotted, so that the thread one on such The attached coin slides into this slot as soon as the coin is below the bend in the channel has arrived With this, the withdrawal of the thread coin is made impossible. To the A coiled wire spring is used to further increase safety in the aforementioned arrangement attached so that they meet the slotted area of the inner curve of the inlet channel crossed. As a result, the thread also gets caught in the spring in the slot. With this construction it seems impossible that a thread coin will be used again can be pulled out of the self-cashier, but it is still possible let the coin slide through the coin validator into the cashier and the latter to simulate the insertion of several coins by moving the coin up and down.

Der Erfindung liegt die Aufgabe zugrunde, eine Sperre für Fadenmünzen zu schaffen, durch die das Vordringen der Münze bis zur Kassiereinrichtung unterbunden wird. Gelöst wird diese Aufgabe durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.The invention is based on the object of a lock for thread coins to create, through which the advance of the coin to the cashier is prevented will. This object is achieved by what is specified in the characterizing part of claim 1 Characteristics. Advantageous further developments can be found in the subclaims.

Durch die angegebenen konstruktiven Maßnahmen wird die gestellte Aufgabe erfüllt und eine funktionssichere Sperre für Selbstkassierer bereitgestellt, die das Eindringen von Fadenmilnzen zuverlässig verhindert.The given task is achieved by the specified constructive measures fulfilled and a functionally reliable lock provided for self-checkers who reliably prevents the penetration of thread spleen.

An einem Ausführungsbeispiel wird die Erfindung nunmehr eingehend beschrieben. Die Figuren 1 ind 2 der zugehörigen Zeichnung zeigen den erfindungsgemäßen Fadenfänger mit festschaltener Münze in zwei Ansichten.The invention will now be described in detail using an exemplary embodiment described. Figures 1 and 2 of the accompanying drawing show the invention Thread catcher with locked coin in two views.

Die Miinze M ist an einem Faden F befestigt, z.B.The coin M is attached to a thread F, e.g.

durch Klebstoff, und kann an diesem im Münzkanal eines Selbstkassierers auf- und abbewegt werden.by adhesive, and can be attached to this in the coin channel of a self-cashier be moved up and down.

Um dies zu verhindern, ist in dem Münzkanal ( nicht dargestellt ) an einer Stelle, an der dieser die Richtung ändert, also an einer Biegung, einem knick oder auch an einem Absatz, an dem die Münze ein drück fällt, mit der Fadenfänger 1 versehen.To prevent this, the coin channel (not shown) at a point where it changes direction, i.e. at a bend, a kink or at a paragraph where the coin is pressed with the thread catcher 1 provided.

Dieser Fadenfänger besteht aus einer Schraubenfeder 2, in die eine zweite Schraubenfeder 3 kleineren Durchmessers eingeschoben ist. Die Differenz der beiden Durchmesser braucht nur so groß zu sein, daß sich die kleine Feder einschieben lässt.This thread catcher consists of a coil spring 2, in which one second coil spring 3 of smaller diameter is inserted. The difference in both diameter only needs to be large enough for the small spring to slide in leaves.

Vorzugsweise sind beide Schraubenfedern gegenläufig gewendelt, z.B. die äußere (2) links und die innere (3) rechts. Ferner ist es zweckmäßig, daß beide Schraubenfedern die gleiche Steigung haben, weil sie sich dann so ausrichten lassen, daß die Windungen der einen Feder genau zwischen denen der anderen Feder stehen.Preferably both coil springs are coiled in opposite directions, e.g. the outer (2) on the left and the inner (3) on the right. It is also useful that both Coil springs have the same pitch because they can then be aligned that the turns of one spring are exactly between those of the other spring.

Der Fadenfänger 1 kann in mehr oder weniger spitzem Winkel zur Münzenlaufrichtung angeordnet sein. Läuft eine Fadenmünze M über ihn hinweg in den tiefer gelegenen, nachfolgenden Kanalabschnitt, so gerät der Faden F zwangsläufig zwischen die Windungen der Schraubenfedern 2 und 3 und klemmt sich dort fest.The thread catcher 1 can be at a more or less acute angle to the direction of travel of the coin be arranged. If a thread coin M runs over him into the lower, following channel section, the thread F inevitably gets between the turns of coil springs 2 and 3 and is stuck there.

Die Fadenmünze M kann dann zwar wieder rückwärts herausgezogen werden, doch ist es unmöglich, sie weiter in das Gerät, inshesondere bis zur Kassiereinrichtung, hinein zu befördern. Dadurch werden einerseits betrügerische Manipulationen, andererseits aber auch Verstopfungen durch hängengebliebene Fadenmünzen vereitelt.The thread coin M can then be pulled out backwards again, but it is impossible to move them further into the device, especially up to the cash desk, to convey into it. This prevents fraudulent manipulations on the one hand, and on the other but also blockages by sticking thread coins thwarted.
