Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Münzpfandschloß, insbesondere zur Verwendung bei Einkaufswagen.The invention relates to a coin deposit lock, in particular for use in shopping trolleys.

Zur Sicherung und ordnungsgemäßen Verwahrung von Einkaufswagen beispielsweise auf dem Parkplatz vor einem Supermarkt ist es in den letzten Jahren zunehmend üblich geworden, die Einkaufswagen mit Münzpfandschlössern auszurüsten. Die Funktion derartiger Münzpfandschlösser besteht darin, daß die Entnahme eines leeren Einkaufswagens bei Einkaufsbeginn beispielsweise aus einer Reihe von abgestellten Einkaufswagen, nur dann möglich ist, wenn durch Einschub einer Münze in das Münzpfandschloß die Arretierung eines Schlüssels im Münzpfandschloß gelöst wird, der in der Regel über eine Kette mit dem nächsten Einkaufswagen fest verbunden ist. Während des Einkaufes befindet sich die eingelegte Münze folglich als Pfand innerhalb des Münzpfandschlosses und kann von außen nicht entnommen werden.For example, to secure and properly store shopping carts In the parking lot in front of a supermarket, it has become increasingly common in recent years to equip the shopping trolleys with coin locks. The function Such coin-operated locks is that the removal of an empty shopping cart at the start of shopping, for example, from a number of parked Shopping cart, is only possible if by inserting a coin into the Coin deposit lock the locking of a key in the coin deposit lock is released, which is usually connected to the next shopping trolley by a chain. The inserted coin is therefore within the deposit as a deposit of the coin deposit lock and cannot be removed from the outside.

Wenn nach getätigtem Einkauf der wiederum leere Einkaufswagen an die hierfür vorgesehene Einkaufswagenreihe gebracht wird und dort in diese Reihe eingeschoben wird, kann in Umkehrung der beschriebenen Reihenfolge der mit dem nächsten Einkaufswagen fest verbundene Schlüssel wieder in das Münzpfandschloß eingegeben werden und die eingelegte Pfandmünze wird wieder zur Entnahme freigegeben.If after the purchase has been made, the empty shopping cart in turn goes to the designated one Shopping cart row is brought and inserted into this row can, in reverse order described with the next shopping cart firmly connected key entered into the coin deposit lock again and the inserted coin will be released for withdrawal.

Wenn alle Einkaufswagen im Bereich beispielsweise eines Supermarktes mit derartigen gleichartigen Münzpfandschlössern ausgerüstet sind, wird dadurch in der Regel erreicht oder zumindest gefördert, daß Diebstähle von Einkaufswagen unterbleiben oder minimiert werden und daß nach erfolgtem Einkauf die Käufer die leeren Einkaufswagen wieder an die hierfür vorgesehenen Stellen zurückbringen, um die Pfandmünze wieder zu erhalten. If all shopping carts in the area of a supermarket with such similar coin deposit locks are usually equipped achieved or at least encouraged that theft of shopping carts is avoided or be minimized and that after the purchase the buyers empty the shopping trolleys bring them back to the places provided for this To get deposit coin again.

Derartige Münzpfandsysteme reduzieren folglich beim Betreiber des jeweiligen Supermarktes die Aufwendungen für Neubeschaffung von Einkaufswagen und Personalaufwendungen zum Zusammensuchen der ansonsten in der Regel weit über den Kundenparkplatz verstreuten Einkaufswagen.Such coin deposit systems therefore reduce the operator of the respective supermarket expenses for new shopping carts and personnel expenses to find the otherwise usually far above the Customer parking lot scattered shopping carts.

Stand der TechnikState of the art

Die Konstruktion solcher Münzpfandschlösser stellt relativ hohe Anforderungen an die Robustheit und mechanische Stabilität der konstruktiven Auslegung, da die Münzpfandsysteme allen Wettereinflüssen ausgesetzt sind, mit schonendem Gebrauch durch die Kunden nicht gerechnet werden kann, Reparatur- und Ersatzaufwendungen soweit wie möglich reduziert werden müssen, um keine zusätzlichen Kosten entstehen zu lassen.The design of such coin deposit locks places relatively high demands on the Robustness and mechanical stability of the constructive design, as the coin deposit systems are exposed to all weather influences with gentle use cannot be expected by customers, repair and replacement expenses must be reduced as much as possible in order not to incur any additional costs allow.

Das Dokument GB-A-2276482 beschreibt ein Münzpfandschloß für Einkaufswagen, mit Münzkammer und Schlüsselkammer mit mindestens einem Funktionsteil, das bei Einführung einer Münze einen Schlüssel freigibt und umgekehrt, wobei das Funktionsteil ein Drehteil ist, dessen vorderer Bereich an die Münzkammer und dessen hinterer Bereich an die Schlüsselkammer angrenzt,The document GB-A-2276482 describes a coin deposit lock for shopping carts Coin chamber and key chamber with at least one functional part, which is introduced releases a key to a coin and vice versa, the functional part being a turned part, its front area to the coin chamber and its rear area to the Key chamber adjoins,

Das Dokument US-A-5377806 beschreibt ein Münzpfandschloß für Einkaufswagen, mit Münzkammer und Schlüsselkammer mit mindestens einem Funktionsteil, das bei Einführung einer Münze einen Schlüssel freigibt und umgekehrt, unter Verwendung eines in Bewegungsrichtung von Münze und Schlüssel von diesen verschiebbarem Steuerteil, wobei das Funktionsteil ein Drehteil ist, und dessen vorderer Bereich an die Münzkammer und dessen hinterer Bereich an die Schlüsselkammer angrenzt, das Drehteil über Steuerkonturen in einem Schlitz des Schlüssels geführt ist, daß bei einer Verschiebung des Steuerteils zwischen zwei Endpositionen eine Drehung des Drehteils zwischen zwei End-Winkelpositionen erfolgt.The document US-A-5377806 describes a coin deposit lock for shopping carts Coin chamber and key chamber with at least one functional part, which is introduced releases a key to a coin and vice versa, using an in Direction of movement of the coin and key of this sliding control part, wherein the functional part is a turned part, and its front area to the coin chamber and whose rear area adjoins the key chamber, the rotating part above Control contours is guided in a slot of the key that when the Control part between two end positions a rotation of the rotating part between two End angular positions are done.

Ein aus EP 0 686 294 B1 bekanntes System weist zur Durchführung der oben beschriebenen Vorgänge vier Funktionsteile auf, die bei Einschub einer Münze in eine Münzkammer den in einer Schlüsselkammer gehaltenen Schlüssel, der die Verbindung mit dem nächsten Einkaufswagen herstellt, freigeben und umgekehrt; der Schlüssel besteht hierbei aus einem Metall-Funktionsteil zur Wechselwirkung mit dem Funktionsteil und dem Sperriegel, sowie einem dieses Metall-Funktionsteil umhüllenden Kunststoff-Griffabschnitt.A system known from EP 0 686 294 B1 has four functional parts for performing the operations described above on when a coin is inserted into a coin chamber or in a key chamber held key that connects to the next shopping cart manufactures, releases and vice versa; the key consists of a metal functional part for interaction with the functional part and the locking bolt, as well a plastic handle section enveloping this metal functional part.

Bei dem bekannten System ist die Ausbildung der Funktionsteile und ihre Verankerung im Münzpfandschloß aufwendig und erfordert viel Platz, um die beschriebene Funktion zu erreichen.In the known system, the formation of the functional parts and their anchoring in the coin deposit lock complex and requires a lot of space to the described To achieve function.

Darstellung der ErfindungPresentation of the invention

Es ist eine wesentliche Aufgabe der Erfindung, ein Münzpfandschloß so auszubilden, daß es mit noch einfacheren baulichen Maßnahmen hergestellt werden kann, in Herstellung und Gebrauch äußerst wirtschaftlich und robust ist und somit Herstellungsund Betriebskosten minimiert werden. wobei insbesondere der Einsatz eines Schlüssels aus Vollkunststoff ermöglicht werden soll. It is an essential object of the invention to design a coin deposit lock in such a way that it can be manufactured with even simpler structural measures, in production and use is extremely economical and robust and thus manufacturing and Operating costs can be minimized. in particular the use of a key made of all-plastic.

Die oben beschriebenen Aufgaben werden durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The tasks described above are characterized by the characteristics of the Part of claim 1 solved.

Der Grundgedanke der Erfindung besteht also zunächst darin, daß die Anzahl der verwendeten Bauteile weiter minimiert wird, wobei diese Bauteile durch ihre jeweiligen Innenkonturen bzw. Außenkonturen die Bewegungsabläufe innerhalb des Münzpfandschlosses zwischen den jeweiligen Endpositionen, Verriegelungsposition und Freigabeposition, selbständig steuern.The basic idea of the invention is therefore first that the number of components used is further minimized, these components by their respective Inner contours or outer contours the movement sequences within the coin deposit lock between the respective end positions, locking position and release position, control independently.

Die Verlegung der Steuerkurve(n) in das Drehteil/die Drehteile schafft Freiraum für einen großen lichten Querschnitt innerhalb der Schlüsselkammer und damit für einen Schlüssel mit entsprechendem Querschnitt, wie er bei einem Kunststoffschlüssel aus Stabilitätsgründen erforderlich ist.Laying the control cam (s) in the turned part (s) creates space for a large clear cross section within the key chamber and thus for one Key with the appropriate cross-section, as it is made of a plastic key Stability reasons is required.

Mit diesem Konzept ist es im Extremfall möglich, das gesamte Münzpfandschloß mit nur einem Drehteil als Funktionsteil und einem Steuerteil in einem zweiteiligen Gehäuse aufzubauen, wobei alle diese Bauteile vorteilhafterweise aus einem widerstandsfähigen Kunststoffmaterial, beispielsweise durch Spritzguß hergestellt sein können, und insbesondere auch Federelemente hierbei integriert sein können.With this concept it is possible in extreme cases to carry the entire coin deposit lock with you only a turned part as a functional part and a control part in a two-part housing to build, all of these components advantageously from a resistant Plastic material, for example, be produced by injection molding can, and in particular also spring elements can be integrated here.

Minimaler Herstellungsaufwand durch die Möglichkeit einfacher Kunststoffteile auch für den Schlüssel einerseits und minimaler Aufwand für die Montage durch bausatzähnliches Zusammenfügen dieser Bauteile andererseits garantieren minimale Ausrüstungskosten bei größtmöglicher Robustheit im täglichen Einsatz.Minimal manufacturing effort due to the possibility of simple plastic parts too for the key on the one hand and minimal effort for assembly by On the other hand, assembly of these components similar to a kit guarantees minimal Equipment costs with the greatest possible robustness in daily use.

Weitere vorteilhafte Ausgestaltungen und Vorteile gehen aus der nachfolgenden Beschreibung und den Unteransprüchen hervor.Further advantageous refinements and advantages emerge from the description below and the dependent claims.

Bevorzugtes AusführungsbeispielPreferred embodiment

Die Figuren zeigen das bevorzugte Ausführungsbeispiel des erfindungsgemäßen Münzpfandschlosses in seinen beiden Endpositionen, jeweils in einer Aufsicht (Figur 1 und Figur 3) und vier Schnittdarstellungen (Figur 2 und Figur 4), wobei in der Aufsichtdarstellung der Figuren 1 und 3 die obere Abdeckung 101 des Gehäuses 1 weggenommen ist. Zur Verdeutlichung der Darstellung ist in Figur 1 der Boden der somit sichtbaren unteren Abdeckung 102 schraffiert dargestellt.The figures show the preferred embodiment of the invention Coin deposit lock in its two end positions, each in a top view (Figure 1 and Figure 3) and four sectional views (Figure 2 and Figure 4), being in the top view 1 and 3, the top cover 101 of the housing 1 is removed is. In order to clarify the illustration, the bottom of FIG. 1 is thus visible lower cover 102 shown hatched.

Die untere Abdeckung 102 besteht aus einer im wesentlichen rechteckigen Kunststoffplatte, in deren Randbereichen Lager N eingebracht sind, die zur Aufnahme von zwei Walzen 2A,2B dient, die parallel zu den Seitenwandungen des Gehäuses 1 liegen.The lower cover 102 consists of an essentially rectangular plastic plate, in the edge regions of which bearings N are introduced, which are used to hold serves two rollers 2A, 2B, which are parallel to the side walls of the housing 1.

In die von der unteren Abdeckung 102 und den beiden seitlich gelagerten Walzen 2A,2B somit gebildete wannenähnliche Struktur der unteren Abdeckung 102 ist ein Steuerteil 5 eingelegt, und zwar derart, daß Noppen 10A,10B am Steuerteil 5 in eine rechteckige Steuerrinne 11 in der unteren Abdeckung 102 eintauchen, so daß bestimmte Bewegungsabläufe des Steuerteils 5 innerhalb des Gehäuses 1 auf der unteren Abdeckung 102 damit definiert sind bzw. die Randbedingungen für solche Bewegungsabläufe vorgegeben sind. In the of the lower cover 102 and the two laterally mounted rollers 2A, 2B thus formed trough-like structure of the lower cover 102 is one Control part 5 inserted, in such a way that knobs 10A, 10B on the control part 5 in a Immerse the rectangular trough 11 in the lower cover 102 so that certain Movements of the control part 5 within the housing 1 on the lower Cover 102 are defined or the boundary conditions for such movements are specified.

Das Steuerteil 5 besteht aus zwei baugleichen Steuerelementen 5A,5B, die mittels einer Feder in Richtung zu den Walzen 2A,2B hin auseinandergedrückt werden. In dem zur Münze 13 zeigenden Teil des Münzpfandschlosses, der Münzkammer 3, sind die beiden Steuerelemente 5A,5B zangen- oder gabelartig ausgebildet, derart, daß sie von der Münze 13 bei deren Einschub betätigt werden können.The control part 5 consists of two identical control elements 5A, 5B, which means a spring in the direction of the rollers 2A, 2B are pushed apart. In the part of the coin deposit lock, the coin chamber 3, which faces the coin 13 the two control elements 5A, 5B designed like pliers or fork, such that they can be operated by the coin 13 when it is inserted.

Der rückwärtige Abschnitt der Steuerelemente 5A,5B ist komplementär zur Stirnseite des Schlüssels 12 ausgebildet, derart, daß eine Beaufschlagung der Steuerelemente 5A,5B beim Einschub des Schlüssels 12 erfolgen kann.The rear section of the control elements 5A, 5B is complementary to the end face of the key 12 formed such that an application of the controls 5A, 5B when the key 12 is inserted.

Die Walzen 2A,2B und die Steuerelemente 5A,5B sind baugleich und spiegelbildlich zur Längsachse des Gehäuses 1 gehalten, insoweit auch eine symmetrische Funktion gegeben ist.The rollers 2A, 2B and the control elements 5A, 5B are identical in construction and are mirror images held to the longitudinal axis of the housing 1, in so far also a symmetrical function given is.

An ihrem rückwärtigen Abschnitt weisen die Steuerelemente 5A,5B eine Steuerkontur 6 auf, die beim dargestellten Ausführungsbeispiel als Zapfen ausgebildet ist, der in eine am Walzenmantel 2A bzw. 2B eingebrachte Steuerkurve 7A,7B hineinragt. Insbesondere aus der Schnittdarstellung der Figur 2D und 4D wird die Funktion dieser Steuerkurven 7A,7B deutlich, die nämlich darin besteht, eine Verschiebung des Steuerteils 5 in der Längsachse des Gehäuses zwischen seinen beiden Endpositionen in eine Rotation der beiden Walzen 2A,2B um einen entsprechenden Steuerwinkel in zwei entsprechende End-Winkelpositionen α1 bzw. α2 umzusetzen.The control elements 5A, 5B have a control contour at their rear section 6, which is formed in the illustrated embodiment as a pin that in a control cam 7A, 7B introduced on the roller jacket 2A or 2B protrudes. In particular the function of these becomes from the sectional representation of FIGS. 2D and 4D Control curves 7A, 7B clearly, which is namely a shift of the control part 5 in the longitudinal axis of the housing between its two end positions in a rotation of the two rollers 2A, 2B by a corresponding control angle in implement two corresponding end angular positions α1 and α2.

Die beiden Walzen 2A,2B weisen in der Nähe ihrer Stirnseite Sperrkonturen 8 bzw. 9 auf, die etwa um den Steuerwinkel umfangsseitig gegeneinander versetzt sind. Diese Sperrkonturen sind beim dargestellten Ausführungsbeispiel als Nasen oder Zungen ausgebildet und zeigen in Richtung zur Münzkammer 3 bzw. Schlüsselkammer 4.The two rollers 2A, 2B have locking contours 8 and 9 near their end faces that are circumferentially offset from each other by about the head angle. This Locking contours are in the illustrated embodiment as noses or tongues trained and point towards the coin chamber 3 or key chamber 4th

Das Grundprinzip dieser Lösung besteht nun darin, daß diese Sperrkonturen 8,9 an den Walzen 2A,2B je nach Position des Steuerteils 5 wechselweise entweder in die Münzkammer 3 einschwenken, wo sie die Münze 13 blockieren, oder aber in die Schlüsselkammer 4, wo sie den Schlüssel 12 blockieren, der hierzu entsprechende Ausnehmungen 12A,12B aufweist. Durch die umfangsmäßige Versetzung der beiden Sperrkonturen ist gewährleistet, daß entweder Münzkammer oder Schlüsselkammer gesperrt ist, wobei der Einschub einer Münze 13 in die Münzkammer 3 die Freigabe der Schlüsselkammer durch Wegschwenken der Sperrkontur 9 bewirkt ,und umgekehrt der Einschub eines Schlüssels 12 die Freigabe der Münzkammer 3 zum Auswurf der Münze 13.The basic principle of this solution is that these locking contours 8.9 the rollers 2A, 2B either depending on the position of the control part 5 either in the Swing in the coin chamber 3 where they block the coin 13, or into the Key chamber 4, where they block the key 12, the corresponding one Has recesses 12A, 12B. Due to the circumferential displacement of the two Locking contours ensures that either coin chamber or key chamber is blocked, the insertion of a coin 13 into the coin chamber 3 the release the key chamber by pivoting away the locking contour 9, and vice versa the insertion of a key 12 the release of the coin chamber 3 for ejection the coin 13.

Anhand der Figuren 1 und 3 sollen die grundsätzlichen Funktionen nochmals kurz beschrieben werden:The basic functions will be briefly described again with reference to FIGS. 1 and 3 become:

Bei der ersten Endposition des Münzpfandschlosses (Figur 1 und 2) befindet sich der Schlüssel 12 in der Schlüsselkammer 4, in dieser Position sind die beiden Steuerkonturen 6A,6B in der dargestellten Position; der ersten Endposition des Steuerteils 5 entspricht also eine erste Winkelposition der beiden Walzen 2A,2B. In dieser Winkelposition sind die Sperrkonturen 9A,9B in die Ausnehmungen 12A,12B des Schlüssels 12 im Bereich der Schlüsselkammer 4 eingeschwenkt, so daß der Schlüssel 12 nicht aus dem Münzpfandschloß entnommen werden kann und folglich der mit dem Münzpfandschloß verbundene Einkaufswagen an die Einkaufswagenreihe gekettet ist.In the first end position of the coin deposit lock (Figures 1 and 2) is the Key 12 in the key chamber 4, in this position are the two control contours 6A, 6B in the position shown; the first end position of the control part 5 corresponds to a first angular position of the two rollers 2A, 2B. In this angular position are the locking contours 9A, 9B in the recesses 12A, 12B of the key 12 pivoted in the area of the key chamber 4, so that the key 12 is not can be removed from the coin deposit lock and consequently the one with the coin deposit lock connected shopping cart is chained to the shopping cart row.

In dieser Position sind die beiden Steuerelemente 5A,5B infolge ihrer Führung über die Noppen 10A,10B in der Steuerrinne 11 so positioniert, daß die gabelähnlichen Enden der Steuerelemente in die Münzkammer 3 ragen. Die Sperrkonturen 8A,8B sind aus dem Münzschlitz, der in die Münzkammer 3 führt, weggeschwenkt, so daß der Einschub einer Münze 13 möglich ist.In this position, the two control elements 5A, 5B are over due to their guidance the knobs 10A, 10B positioned in the control trough 11 so that the fork-like ends of the controls protrude into the coin chamber 3. The locking contours 8A, 8B are pivoted away from the coin slot, which leads into the coin chamber 3, so that the Inserting a coin 13 is possible.

Beim Einschub einer solchen Münze 13 kommt deren vordere Stirnseite mit den beiden entsprechenden Stirnkanten der Gabelarme der Steuerelemente 5A,5B in Kontakt und beim weiteren Einschieben der Münze 13 in die Münzkammer 3 werden die beiden Arme zunächst auseinandergespreizt, bis die beiden Noppen 10A,10B, die sich im vorderen Teil der Steuerrinne 11 befinden, so weit quer zur Gehäuselängsrichtung bewegt worden sind, bis ein Zurückschieben des Steuerteils 5 in den parallel zur Gehäuselängsachse verlaufenden Abschnitten der Steuerrinne 11 möglich ist. Bei dieser Bewegung gleiten die Steuerkonturen 6A,6B in ihrer zugeordneten Steuerkurve 7A,7B und bewirken eine Verdrehung der beiden Steuerwalzen 2A,2B, während nunmehr die beiden vorderen Sperrkonturen 8A,8B "hinter" der Münze 13 einschwenken und gleichzeitig die. Sperrkonturen 9A,9B aus ihrer zugehörigen Ausnehmung 12A,12B in der Seitenflanke des Schlüssels 12 herausschwenken. Bei vollständigem Einschub der Münze 13 in die Münzkammer 3 ist damit der Weg frei zum Herausziehen des Schlüssels 12 und damit zum Entkoppeln des Einkaufswagens von der Einkaufswagenreihe; damit ist die in Figur 3 dargestellte zweite Endposition des Steuerteils 5 und entsprechend auch die zweite End-Winkelposition α2 der Walzen 2A,2B erreicht. Die Münze 13 befindet sich nun vollständig in der Münzkammer und kann aus dieser aufgrund der Sperrung durch die Sperrkonturen 8A,8B auch nicht mehr entnommen werden.When such a coin 13 is inserted, its front face comes with the two corresponding end edges of the fork arms of the control elements 5A, 5B in contact and when the coin 13 is inserted further into the coin chamber 3, the two become Arms first spread apart until the two knobs 10A, 10B that extend are located in the front part of the control trough 11, so far transversely to the longitudinal direction of the housing have been moved until the control part 5 is pushed back parallel to the longitudinal axis of the housing extending sections of the control channel 11 is possible. At this The control contours 6A, 6B slide in movement in their associated control curve 7A, 7B and cause the two control rollers 2A, 2B to twist while now swing the two front locking contours 8A, 8B "behind" the coin 13 and at the same time the. Locking contours 9A, 9B from their associated recess 12A, 12B in swing out the side flank of the key 12. With complete insertion the coin 13 in the coin chamber 3 is thus the way to pull out the Key 12 and thus for decoupling the shopping cart from the shopping cart row; 3 is the second end position of the control part 5 and correspondingly, the second end angular position α2 of the rollers 2A, 2B is also reached. The Coin 13 is now completely in the coin chamber and can be due to this the blocking by the blocking contours 8A, 8B can also no longer be removed.

Entsprechend in umgekehrter Reihenfolge sind die Abläufe beim Einschieben des Schlüssels 12 und anschließender Entnahme der Münze 13:The procedures for inserting the are accordingly in reverse order Key 12 and subsequent removal of the coin 13:

Bei Einführung des Schlüssels 12 in die Schlüsselkammer 4 kontaktiert eine zentrale Zunge 12C zunächst einen Zwischenraum 5C zwischen den beiden beabstandeten hinteren Bereichen der beiden Steuerelemente 5A,5B und drückt diese so weit auseinander, bis die rückwärtigen beiden Noppen 10A,10B den in der Gehäuselängsachse verlaufenden Abschnitt der Steuerrinne 11 erreichen. Eine weitere Beaufschlagung des Steuerteils 5 durch den Schlüssel 12 führt dann dazu, daß der Steuerriegel 5 in Richtung zur Münzkammer 3 verschoben wird, wobei gleichzeitig die beiden Walzen 2A,2B durch die Bewegung der Steuerkonturen 6A,6B in den Steuerkurven 7A,7B im entgegengesetzten Sinne zur ersten End-Winkelposition α1 zurückgedreht werden, so daß die münzseitigen Sperrkonturen 8A,8B aus der Münzkammer 3 herausschwenken und die Münze 13 vollständig vom Steuerteil 5 ausgeworfen werden kann, womit dann wieder die in Figur 1 dargestellte erste Endposition erreicht ist.When the key 12 is inserted into the key chamber 4, a central contact is made Tongue 12C first a space 5C between the two spaced rear areas of the two control elements 5A, 5B and pushes them so far apart, until the rear two knobs 10A, 10B in the longitudinal axis of the housing Reaching section of the control trough 11. Another charge of the control part 5 by the key 12 then leads to the control bolt 5 in Direction to the coin chamber 3 is shifted, with the two rollers simultaneously 2A, 2B by the movement of the control contours 6A, 6B in the control curves 7A, 7B in in the opposite sense to the first end angular position α1, so that the coin-side blocking contours 8A, 8B pivot out of the coin chamber 3 and the coin 13 can be completely ejected by the control part 5, with which the first end position shown in FIG. 1 is then reached again.
