Aus WO 90/07167 ist ein Pfandschloß bekannt, bei dem durch das Einführen einer Münze ein Steuerteil betätigt wird, das einen Schließriegel entsperrt. In FR 2526189 ist die Verwendung eines derartigen Pfandschlosses an Einkaufswagen gezeigt. Die Pfandschlösser sind an Einkaufswagen befestigt, um einen Wagen an den anderen anzukuppeln, wobei diese durch Einführen einer Münze oder einer Loch- oder Magnetkarte voneinander lösbar sind. Aus FR 2 584 839 ist es bekannt, wahlweise Münzen verschiedener Größe zu verwenden. Dazu ist das Pfandschloß mit Schlitzen verschiedener Größen versehen. Diese bekannten Pfandschlösser weisen verhältnismäßig viele Teile auf und besitzen große Außenabmessungen. Insbesondere wird bei keinem der gezeigten Pfandschlösser der Schließriegel direkt vom Steuerteil von einer Sperrenden in eine entsperrende Stellung bewegt.A deposit lock is known from WO 90/07167, at which operated a control part by inserting a coin unlocks a locking bolt. In FR 2526189 is the use of such a deposit lock shown on shopping cart. The deposit locks are attached to shopping carts around a cart to couple to the other, this by insertion a coin or a punch card or magnetic card are detachable from each other. From FR 2 584 839 it is known optionally use coins of different sizes. In addition, the deposit lock with slots is different Provided sizes. These well-known deposit locks have a relatively large number of parts and have large external dimensions. In particular is not the one of the deposit locks shown Lock bolt directly from the control part of a locking end moved to an unlocking position.

Aus WO 88/01084 ist ein Pfandschloß nach dem Oberbegriff des Anspruchs 1 bekannt, bei dem wie bei den o.g. Dokumenten das Steuerteil den Schließriegel lediglich freigibt und nicht sperrt bzw. entsperrt.From WO 88/01084 a deposit lock according to the The preamble of claim 1 is known, in which as in the above Documents the control unit the locking bolt only releases and does not lock or unlock.

Aufgabe der Erfindung ist es, ein Pfandschloß der eingangs genannten Art so zu verbessern, daß es bei hoher Zuverlässigkeit, wenig Teilen und einfacher Herstellung geringe Außenabmessungen besitzt.The object of the invention is a deposit lock type mentioned to improve so that it at high reliability, few parts and simple manufacture has small external dimensions.

Diese Aufgabe wird erfindungsgemäß nach dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved according to the characterizing part of claim 1.

Das Gehäuse dieses Pfandschlosses bildet ein kleines flaches Kästchen, das bei geringem Gewicht an verschiedenen Stellen der anzukoppelnden Teile insbesondere der Einkaufswagen oder Gepäckwagen befestigbar ist. Hierbei besitzt das Schloß eine hohe Funktionssicherheit und Aufbruchsicherheit. Das Kopplungsglied ist im verriegelten Zustand auch bei Anwendung roher Kräfte nicht herausziehbar.The housing of this deposit lock forms one small flat box that is light in weight different places of the parts to be coupled in particular the shopping cart or luggage cart can be attached is. The lock has a high level of functional reliability and security against break-ins. The coupling link is in the locked state even when in use raw forces not extractable.

Besonders vorteilhaft ist es hierbei, daß das Schloß wahlweise, sowohl von einer Münze als auch von einer Karte, betätigbar ist, und dass die im Schloß angeordneten beweglichen Teile nur kleinste Wege ausführen, so daß auch nur kleine Betätigungsbewegungen durch das Pfand und das Kopplungsglied ausgeführt werden müssen.It is particularly advantageous here that the castle optionally, both from a coin and from one Card that can be operated, and that arranged in the castle only move the smallest parts, so that even small actuation movements the deposit and the coupling member are executed have to.

Von besonderem Vorteil ist es, wenn der Schließrigel ein um eine Achse drehbares Teil ist. Hierbei kann der Schließrigel über ein Getriebe insbesondere ein Kurbelgetriebe mit dem Steuerteil verbunden sein. Ein in dieser Weise ausgeführter Schließriegel stellt sich einem Herausziehen des Kopplungsgliedes besonders sicher entgegen, da ein Herausziehen nur noch ein stärkeres Verriegeln erzeugt.It is particularly advantageous if the locking bar is a part rotatable about an axis. Here can the locking bar in particular via a gearbox Crank gearbox be connected to the control part. On Lock bolt designed in this way turns itself Pulling out the coupling member especially certainly counter, since pulling out is only a stronger one Lock creates.

Besonders vorteilhaft ist es, wenn das Steuerteil ein Schlitten oder Wagen ist, der in Einschubrichtung des Pfandes verschiebbar ist. Auch sollte das Steuerteil durch das Pfand gegen den Druck eines Federelementes verschieblich sein.
Eine sichere Funktion und eine kleine Bauweise werden dadurch erzeugt, daß das Steuerteil mindestens einen Hohlraum aufweist, in dem das Kopplungsglied und/oder der Schließriegel einliegt. Hierbei wird vorteilhafter Weise vorgeschlagen, daß das Steuerteil mindestens einen Anschlag für die Karte und/oder Münze aufweist. Damit übernimmt das Steuerteil wichtige Funktionen des Schlosses, da es sowohl durch das Kopplungsglied als auch durch die Münze und/oder die Karte bewegt wird.It is particularly advantageous if the control part is a carriage or carriage that can be moved in the direction of insertion of the deposit. The control part should also be displaceable by the deposit against the pressure of a spring element.
A safe function and a small design are generated in that the control part has at least one cavity in which the coupling member and / or the locking bolt lies. It is advantageously proposed that the control part has at least one stop for the card and / or coin. The control part thus takes over important functions of the lock, since it is moved both by the coupling member and by the coin and / or the card.

Besonders vorteilhaft ist es, wenn die Karte und/oder Münze im eingesteckten Zustand durch ein Sicherungsteil arretiert sind, das durch das eingesteckte Kopplungsglied in die nicht sperrende Stellung bewegbar ist. Hierbei kann das Sicherungsteil durch das Kopplungsglied gegen den Druck eines Federelementes in die nicht sperrende Stellung bewegbar sein.It is particularly advantageous if the card and / or Coin in the inserted state through a security part are locked by the plugged in Coupling member movable into the non-locking position is. Here, the securing part by the coupling member against the pressure of a spring element in the non-blocking position can be moved.

Auch wird vorteilhafter Weise vorgeschlagen, daß das Sicherungsteil mindestens eine Schulter aufweist, die die Münze und/oder die Karte im eingesteckten Zustand an der Rückseite arretierend hintergreift. Hierbei kann das Sicherungsteil mindestens einen Vorsprung insbesondere Stift aufweisen, der in eine Öffnung der Münze und/oder der Karte eindringt.It is also advantageously proposed that the securing part has at least one shoulder, the coin and / or card when inserted reaches behind at the rear. in this connection the securing part can have at least one projection in particular have pin which in an opening of the Coin and / or card penetrates.

Eine sichere Funktion und eine kleine Bauweise werden dadurch erzeugt, daß das Steuerteil mindestens einen Hohlraum aufweist, in dem das Kopplungsglied und/oder der Schließriegel einliegt. Hierbei wird vorteilhafter Weise vorgeschlagen, daß das Steuerteil mindestens einen Anschlag für die Karte und/oder Münze aufweist. Damit übernimmt das Steuerteil wichtige Funktionen des Schlosses, da es sowohl durch das Kopplungsglied als auch durch die Münze und/oder die Karte bewegt wird.A safe function and a small design are generated in that the control part at least has a cavity in which the coupling member and / or the locking bolt is inserted. Here will advantageously proposed that the control part at least one stop for the card and / or coin having. So the control part takes over important Functions of the castle, since it is both through the Coupling link as well as by the coin and / or the Card is moved.

Besonders vorteilhaft ist es, wenn die Karte und/oder Münze im eingesteckten Zustand durch ein Sicherungsteil arretiert sind, das durch das eingesteckte Kopplungsglied in die nicht sperrende Stellung bewegbar ist. Hierbei kann das Sicherungsteil durch das Kopplungsglied gegen den Druck eines Federelementes in die nicht sperrende Stellung bewegbar sein.It is particularly advantageous if the card and / or Coin in the inserted state through a security part are locked by the plugged in Coupling member movable into the non-locking position is. Here, the securing part by the coupling member against the pressure of a spring element in the non-blocking position can be moved.

Auch wird vorteilhafter Weise vorgeschlagen, daß das Sicherungsteil mindestens eine Schulter aufweist, die die Münze und/oder die Karte im eingesteckten Zustand an der Rückseite arretierend hintergreift. Hierbei kann das Sicherungsteil mindestens einen Vorsprung insbesondere Stift aufweisen, der in eine Öffnung der Münze und/oder der Karte eindringt.It is also advantageously proposed that the securing part has at least one shoulder, the coin and / or card when inserted reaches behind at the rear. in this connection the securing part can have at least one projection in particular have pin which in an opening of the Coin and / or card penetrates.

Eine hohe Funktionssicherheit bei kleiner Bauweise, wird erreicht, wenn im Gehäuse ein Lagerbock befestigt insbesondere angeformt ist, der den Schließriegel und/oder das Steuerteil führt.A high level of functional reliability with a small design, is achieved when a bearing block is fastened in the housing is molded in particular, the locking bolt and / or the control part leads.

Eine besonders platzsparende, konstruktiv einfache und sicher arbeitende Bauweise bei kleinsten Steuerbewegungen wird erreicht, wenn der Schließriegel ein etwa geradlinig vom Steuerteil bewegtes Teil ist. Hierbei kann das Steuerteil mindestens eine schräg zu seiner Bewegungsrichtung angeordnete Gleitfläche aufweisen, auf der der Schließriegel insbesondere mit einem Schließriegelvorsprung oder über ein Zwischenteil gleitet. Auch kann hierbei die Gleitfläche von einem Schrägschlitz im Steuerteil gebildet werden.A particularly space-saving, structurally simple and safe working design with the smallest control movements is reached when the deadbolt is on is a part that is moved in a straight line from the control part. in this connection the control unit can be at least one at an angle to it Have arranged sliding surface, on which the locking bolt in particular with a Lock bolt projection or slides over an intermediate part. The sliding surface of an oblique slot can also be used here be formed in the control section.

Das Pfandschloß weist ein quaderförmiges Gehäuse 1 auf, das in Form und Abmessungen etwa der doppelten Größe einer Streichholzschachtel entspricht. Das Gehäuse 1 ist am Boden und verschloßen und besitzt vier senkrechte Seitenwände und einen inneren Hohlraum, der nach oben hin offen ist und durch einen Deckel 6 verschloßen wird. Der an der Oberseite befestigte Deckel 6 wird seitlich aufgeschoben und findet in seitlichen Nuten des Gehäuses 1 Halt.The deposit lock has a cuboid housing 1 on, the shape and dimensions of about twice The size of a matchbox corresponds. The housing 1 is on the bottom and closed and has four vertical side walls and an inner one Cavity that is open at the top and through one Cover 6 is closed. The one attached to the top Lid 6 is slid open laterally and takes place in lateral grooves of the housing 1 stop.

Im Innenraum des Gehäuses 1 ist ein Lagerbock 2 befestigt, insbesondere am Gehäuse angeformt, der mit dem Boden des Gehäuses verbunden ist und über den ein schlittenförmiges Steuerteil 3 gestülpt ist, das im Querschnitt einem umgekehrten U entspricht. Damit umgreift das Steuerteil 3 mit seinen zwei Seitenwänden 3a die beiden Seiten des Lagerbocks 2.A bearing block 2 is located in the interior of the housing 1 attached, in particular molded onto the housing with is connected to the bottom of the housing and over the a sled-shaped control part 3 is slipped in Cross section corresponds to an inverted U. In order to encompasses the control part 3 with its two side walls 3a the two sides of the bearing block 2.

Im Lagerbock 2 ist quer zur Längsrichtung des Gehäuses 1 waagerecht eine Bohrung 2a eingebracht, in der ein verdrehbarer Schließriegel 4 gelagert ist. Der Schließriegel 4 weist an seinen beiden Enden zwei kreisförmige Scheiben 4a und eine dazwischenliegendes Verbindungsteil 4b auf, das außermittig der Scheiben liegt und die sperrende Funktion für das Kopplungsglied 7 hat. An der Außenseite jeder Scheibe 4a steht achsparallel außermittig jeweils ein Stift 4c vor, die als Kurbel zum Verdrehen des Schließriegels 4 dienen.In the bearing block 2 is transverse to the longitudinal direction of the housing 1 drilled a hole 2a horizontally, in a rotatable locking bolt 4 is mounted. The Lock bolt 4 has two at its two ends circular discs 4a and an intermediate one Connecting part 4b, the off-center of the discs lies and the locking function for the coupling member 7 has. On the outside of each disc 4a axially parallel off center each a pin 4c, which as Serve crank to turn the locking bolt 4.

Die Seitenwände 3a des Steuerteils 3 besitzen jeweils einen senkrechten Schlitz 3b in den jeweils ein Stift 4c einliegt. Wird das Steuerteil 3 in Längrichtung des Gehäuses bewegt, so wird der Schließriegel 4 um seine Achse verdreht.The side walls 3a of the control part 3 each have a vertical slot 3b in each Pin 4c is inserted. If the control part 3 in the longitudinal direction of the housing moves, the locking bolt 4 to its axis twisted.

Im Lagerbock 2 befindet sich eine achsparallele Bohrung in der eine Druckfeder 8 gelagert ist, die an einer Querwand 3c des Steuerteils 3 anliegt. Durch die Druckfeder 8 wird das Steuerteil 3 in eine Richtung bewegt, in der die Querwand 3c vom Lagerbock 2 entfernt liegt und der Schließriegel 4 durch die Schlitze 3b in die das Kopplungsglied 7 sperrende Stellung gedreht ist (siehe Figur 1).In the bearing block 2 there is an axially parallel Bore in which a compression spring 8 is mounted, the a transverse wall 3c of the control part 3 rests. Through the Compression spring 8, the control part 3 is moved in one direction, in which the transverse wall 3c is removed from the bearing block 2 lies and the locking bolt 4 through the slots 3b in the the coupling member 7 is rotated locking position (see Figure 1).

Im Lagerbock 2 ist ein Längskanal 2b eingebracht, der dem Querschnitt des Kopplungsgliedes 7 entspricht und der mit einer Öffnung 1a in der Stirnseite des Gehäuses 1 fluchtet. Durch die Öffnung 1a wird das Kopplungsglied 7 eines anzukoppelnden Teiles insbesondes eines Wagens eingesteckt, das bzw. der mit dem Teil bzw. Wagen verkoppelt werden soll an dem das Gehäuse 1 befestigt ist. Das Kopplungsglied 7 weist einen Rücksprung, insbesondere eine Kerbe 7a auf. Wird das Kopplungsglied 7 durch die Öffnung 1a in das Gehäuse 1 hineingeschoben, so verdreht die vordere keilförmige Spitze des Kopplungslieds 7 eine in den Längskananl 2b hineinreichende Fläche des Verbindungsteils 4b, so daß der Schließriegel 4 verdreht wird, wobei er das Steuerteil 3 gegen den Druck der Feder 8 verschiebt. Ist das Kopplungsglied 7 bis in seine Endstellung hineingeschoben, so erreicht seine Kerbe 7a den Schließriegel 4 und das Verbindungsteil 4b schnappt in die Kerbe 7a drehend ein, so daß danach Steuerteil 3 und Schließriegel 4 die in Figur 1 gezeigten Stellungen einnehmen. Das Kopplungsglied 7 kann dann nicht mehr gewaltsam aus dem Schloß herausgezogen werden.A longitudinal channel 2b is introduced in the bearing block 2, which corresponds to the cross section of the coupling member 7 and the one with an opening 1a in the front of the housing 1 is aligned. Through the opening 1a, the coupling member 7 in particular of a part to be coupled a car, the one with the part or car to be coupled to the housing 1 is attached. The coupling member 7 has one Recess, in particular a notch 7a. Will that Coupling member 7 through the opening 1a in the housing 1 pushed in, the front wedge-shaped twists Tip of the coupling link 7 one in the longitudinal channel 2b area of the connecting part 4b, see above that the locking bolt 4 is rotated, whereby he Control part 3 moves against the pressure of the spring 8. If the coupling member 7 is pushed into its end position, so its notch 7a reaches the Lock bolt 4 and the connecting part 4b snaps into the notch 7a turning, so that then control part 3rd and locking bolt 4 the positions shown in Figure 1 take in. The coupling member 7 can then not pulled out of the castle more violently.

An dem dem Schließriegel 4 gegenüberliegenden Ende ist im Innern des Gehäuses 1 ein Sicherungsteil 5 senkrecht verschieblich gelagert das an seiner Oberseite eine Schrägfläche 5a aufweist, die bei eingestecktem Kopplungsglied 7 an einer vorderen Keilfläche des Kopplungsglied 7 bzw. dessen Spitze zur Anlage gelangt. Damit wird durch die Kopplungsgliedspitze das Sicherungsteil 5 gegen den Druck einer in ihr liegenden Druckfeder 9 nach unten in seiner unteren Stellung gehalten.At the locking bolt 4 opposite The end is inside the housing 1, a securing part 5 vertically slidably mounted on its top has an inclined surface 5a which, when inserted Coupling member 7 on a front wedge surface of the Coupling member 7 or its tip comes to rest. So that is through the coupling link tip Securing part 5 against the pressure of one lying in it Compression spring 9 held down in its lower position.

Das Gehäuse 1 weist an der der Öffnung 1a gegenüberliegenden Stirnseite zwei weitere Öffnungen 1b und 1c auf. In die spitzförmige Öffnung 1b ist eine Münze als Pfand einsteckbar, die bei unterer Stellung des Sicherungsteils 5 über die Oberseite des Sicherungsteils 5 so weit in das Gehäuse hineingleitet, daß sie nicht, oder nur noch wenig, außen aus dem Gehäuse herausragt. In dieser weiteingestecktesten Stellung der Münze M wird die Münze von zwei an der Oberseite des Sicherungsteils 5 vorstehenden seitlichen Vorsprüngen 5a hintergriffen, wenn das Kopplungsglied 7 zumindest teilweise abgezogen ist und das Sicherungsteil 5 sich in seiner oberen Stellung befindet, siehe Figur 2.The housing 1 faces the opening 1a opposite Two further openings 1b at the front and 1c. There is a coin in the pointed opening 1b can be inserted as a deposit, which is in the lower position of the Fuse part 5 over the top of the fuse part 5 slides so far into the housing that it not, or only a little, outside of the housing protrudes. In this most inserted position of the Coin M is the coin of two at the top of the Securing part 5 protruding lateral projections 5a behind when the coupling member 7 at least is partially withdrawn and the securing part 5 itself is in its upper position, see Figure 2.

Das Sicherungsteil 5 weist darüber hinaus an seiner Oberseite 2 senkrecht vorstehende Stifte 5b auf, die soweit auseinanderstehen, daß zwischen ihnen die Münze M eingeführt werden kann. Die Stifte 5b ragen in einen Längskanal 10 hineien, der in der schlitzförmigen Öffnung 1c mündet. In die Öffnung 1c und den Kanal 10 ist eine Karte insbesondere in Form einer Kreditkarte oder einer Schlüsselkarte in das Schloß waagerecht einsteckbar, wobei in der Endstellung in der Karte befindliche Löcher über den Stiften 5b stehen, so daß in der oberen Stellung des Sicherungsteils 5 die Stifte 5b die Karte gegen ein Herausziehen arretieren.The securing part 5 also points to it Top 2 vertically protruding pins 5b, the so far apart that between them the Coin M can be inserted. The pins 5b protrude into a longitudinal channel 10, which is in the slot-shaped Opening 1c opens. In the opening 1c and the channel 10 is a card in particular in the form of a credit card or a key card in the lock horizontally insertable, being in the end position in the card holes are above the pins 5b, so that in the upper position of the securing part 5 the pins 5b lock the card against pulling it out.

Der Längskanal 10 ist im Bereich der Öffnung 1c durch eine Verschlußrolle 10 verschlossen, die durch die Karte verschiebbar ist und dafür sorgt, daß Schmutz und Staub in den Kanal 10 nicht eindringen können.The longitudinal channel 10 is in the region of the opening 1c closed by a sealing roller 10 which by the card is slidable and ensures that dirt and dust can not enter the channel 10.

Das Pfandschloß hat folgende Funktionsweise: Wird das Kopplungsglied 7 in die Öffnung 1a eingeschoben, so wird es, wie oben beschrieben, durch den Schließriegel 4 in seiner Endstellung arretiert. In dieser Endstellung drückt das Kopplungsglied 7 das Sicherungsteil 5 in seine den Längskanal 10 und den Münzkanal freigebende Stellung und das Steuerteil 3 befindet sich in seiner den Öffnungen 1b und 1c nahen Stellung, in die das Steuerteil 3 durch die Feder 8 gedrückt wird. Diese Stellung ist in Figur 1 dargestellt.The deposit lock works as follows: If the coupling member 7 is inserted into the opening 1a, so it is, as described above, by the Locking bolt 4 locked in its end position. In this End position, the coupling member 7 presses the securing part 5 in its the longitudinal channel 10 and the coin channel releasing position and the control part 3 is located in its position close to the openings 1b and 1c, in which the control part 3 is pressed by the spring 8. This position is shown in Figure 1.

Wird nun in der Figur 1 dargestellten Stellung in das Schloß eine Münze M oder eine Karte eingeschoben, so drückt die Münze M gegen die Querwand 3c bzw. die Karte gegen einen weit innen liegenden Schlag 3d an der Oberseite des Steuerteils 3. Durch das Einschieben der Münze oder der Karte wird damit das Steuerteil 3 nach rechts von den Öffnungen 1b bzw. 1c weggeschoben gegen den Druck der Feder 8 in die in Figur 2 dargestellte Stellung. Hierbei verdreht das Steuerteil 3 über die Schlitze 3b und die Stifte 4c den Schließriegel 4 in seine freigebende Stellung wobei die innere Oberseite des Verbindungsteils 4b aus der Kerbe 7a des Kopplungsgliedes herausgelangt und eine waagerechte Stellung einnimmt. Damit liegt das Verbindungsteil 4b nicht mehr im Längskanal 2b ein und das Kopplungsglied 7 kann frei herausgezogen werden.Now in the position shown in Figure 1 Lock a coin M or a card inserted, so the coin M presses against the transverse wall 3c or Card against a deep inside blow on 3d the top of the control section 3. By pushing it in the coin or card becomes the control part 3 pushed to the right from the openings 1b and 1c against the pressure of the spring 8 in that shown in Figure 2 Position. Here, the control part 3 rotates the slots 3b and the pins 4c the locking bolt 4 in its releasing position being the inner top of the connecting part 4b from the notch 7a of the coupling member got out and a horizontal position occupies. So that the connecting part 4b is not more in the longitudinal channel 2b and the coupling member 7 can be pulled out freely.

Beim Herausziehen des Kopplungsglieds 7 gibt seine Spitze das Sicherungsteil 5 frei, so daß es sich nach oben bewegen kann und mit dem Vorsprung 5a und/oder den Stiften 5b die Münze und/oder die Karte arretiert. Damit bleiben Münze und/oder Karte so lange im Pfandschloß festgehalten, bis das Kopplungsglied 7 wieder eingesteckt und das Sicherungsteil 5 nach unten in die Freigabestellung durch das Kopplungsglied 7 gedrückt wird.When pulling out the coupling member 7 there are Tip the securing part 5 free, so that it is after can move up and with the projection 5a and / or the coin 5b and / or the card locked. This will keep the coin and / or card in this position for as long Deposit lock held until the coupling member 7 plugged in again and the securing part 5 down pressed into the release position by the coupling member 7 becomes.

Das zweite Ausführungsbeispiel nach Figur 7 und 8 unterscheidet sich von dem nach Figur 1 bis 6 dadurch, daß der Schließriegel durch das Steuerteil nicht gedreht, sondern verschoben wird. Der Schließriegel 4a ist damit rechtwinklig zur Schloßlängsachse und zur Kopplungsgliedlängsachse verschieblich im Gehäuse und/oder im Lagerblock 2 gelagert und weist einen Vorsprung 13 auf, der in einem Schrägschlitz 12 des Steuerteils 3 einliegt. Wird das Steuerteil 3 durch eine Münze/Karte um wenige Millimeter bewegt, so gelangt der Schließriegel 4a aus der Ausnehmung des Kopplungsgliedes und das Kopplungsglied ist frei.The second embodiment of Figure 7 and 8 differs from that according to FIGS. 1 to 6 in that that the locking bolt is not by the control part rotated, but moved. The locking bolt 4a is therefore perpendicular to the longitudinal axis of the castle and to Coupling link longitudinal axis displaceable in the housing and / or stored in the bearing block 2 and has a projection 13 on the in an oblique slot 12 of the control part 3 is inserted. The control part 3 is by a coin / card moved by a few millimeters, the Lock bolt 4a from the recess of the coupling member and the coupling member is free.
