Description

Die Erfindung betrifft ein Pfandschloß für lösbar aneinander zu befestigende Teile, wie Einkaufswagen und Gepäckwagen mit einem am ersten Teil befestigten Schloßgehäuse, das eine Öffnung für ein Pfand und eine Öffnung für ein Kopplungsglied besitzt, das am zweiten Teil befestigt ist und so lange durch einen Schließriegel arretiert gehalten ist, bis das Pfand eingeschoben ist, wobei das Pfand eine Karte und/oder eine Münze ist, die während des Einschiebens ein Steuerteil bewegen.The invention relates to a deposit lock for parts to be detachably fastened to one another, such as shopping trolleys and luggage trolleys, with a lock housing fastened to the first part, which has an opening for a deposit and an opening for a coupling member, which is fastened to the second part and so long by a locking bolt is held locked until the deposit is inserted, the deposit being a card and / or a coin which move a control part during insertion.

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, in which a control part that unlocks a locking bolt is actuated by inserting a coin. FR 2526189 shows the use of such a deposit lock on shopping carts. The deposit locks are attached to shopping carts in order to couple one cart to the other, which can be detached from one another by inserting a coin or a punched or magnetic card. From FR 2 584 839 it is known, optionally coins to use different sizes. For this purpose, the deposit lock is provided with slots of different sizes. These known deposit locks have a relatively large number of parts and have large external dimensions. In particular, in none of the deposit locks shown, the locking bolt is moved directly from the control part by a locking end into an unlocking position.

Aus WO 88/01084 ist ein Pfandschloß nach dem Oberbegriff des Anspruch 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 preamble of claim 1 is known, in which, as with the above. Documents the control part only releases the locking bolt and does not lock or unlock it.

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 to improve a deposit lock of the type mentioned so that it has small external dimensions with high reliability, few parts and simple manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Steuerteil den Schließriegel von der sperrenden in die entsperrte Stellung bewegt, wobei der Schließriegel ein um eine Achse drehbares Teil ist und über ein Getriebe insbesondere ein Kurbelgetriebe mit dem Steuerteil verbunden ist.This object is achieved in that the control part moves the locking bolt from the locking to the unlocked position, the locking bolt being a part rotatable about an axis and being connected to the control part, in particular a crank mechanism.

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 a small flat box, which can be attached to various parts of the parts to be coupled, in particular the shopping trolley or luggage trolley, while being lightweight. The lock has a high level of functional security and security against break-ins. In the locked state, the coupling member cannot be pulled out even when using raw forces.

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 lock can be operated optionally, both from a coin and from a card, and that the movable parts arranged in the lock perform only the smallest paths, so that even small actuation movements are carried out by the deposit and the coupling member Need to become.

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 that can be rotated about an axis. Here, the locking bar can in particular be a gear Crank gearbox to be connected to the control part. A locking bolt designed in this way is particularly reliable against pulling out the coupling member, since pulling out only produces a stronger locking.

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 are locked in the inserted state by a securing part which can be moved into the non-blocking position by the inserted coupling member. Here, the securing part can be moved into the non-locking position by the coupling member against the pressure of a spring element.

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 which engages behind the coin and / or the card in the inserted state in a locking manner on the back. Here, the securing part can have at least one projection, in particular a pin, which penetrates into an opening of the coin and / or the card.

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 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 are locked in the inserted state by a securing part which can be moved into the non-blocking position by the inserted coupling member. Here, the securing part can be moved into the non-locking position by the coupling member against the pressure of a spring element.

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 which engages behind the coin and / or the card in the inserted state in a locking manner on the back. Here, the securing part can have at least one projection, in particular a pin, which penetrates into an opening of the coin and / or the card.

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 if a bearing block is fastened, in particular molded, in the housing, which guides the locking bolt and / or the control part.

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 safely working construction with the smallest control movements is achieved if the locking bolt is a part that moves approximately linearly from the control part. Here, the control part can be inclined at least one have arranged in its direction of movement sliding surface on which the locking bolt slides in particular with a locking bolt projection or via an intermediate part. The sliding surface can also be formed by an oblique slot in the control part.

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, which corresponds in shape and dimensions to approximately twice the size of a matchbox. The housing 1 is at the bottom and closed and has four vertical side walls and an inner cavity which is open at the top and is closed by a cover 6. The lid 6 attached to the top is pushed on to the side and finds 1 hold in the lateral grooves of the housing.

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.In the interior of the housing 1, a bearing block 2 is fastened, in particular molded onto the housing, which is connected to the bottom of the housing and over which a sled-shaped control part 3 is placed, which corresponds in cross section to an inverted U. The control part 3 thus grips the two sides of the bearing block 2 with its two side walls 3a.

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, a bore 2a is made horizontally transversely to the longitudinal direction of the housing 1, in which a rotatable locking bolt 4 is mounted. The locking bolt 4 has at its two ends two circular disks 4a and an intermediate connecting part 4b, which is located off-center of the disks and has the locking function for the coupling member 7. On the outside of each disk 4a, a pin 4c protrudes axially parallel and serves as a crank for rotating 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 of which a pin 4c lies. If the control part 3 is moved in the longitudinal direction of the housing, the locking bolt 4 is rotated about its axis.

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, which bears against a transverse wall 3c of the control part 3. Through the compression spring 8, the control part 3 is in one direction moved, in which the transverse wall 3c is located away from the bearing block 2 and the locking bolt 4 is rotated through the slots 3b into the position blocking the coupling member 7 (see FIG. 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.In the bearing block 2, a longitudinal channel 2b is introduced, which corresponds to the cross section of the coupling member 7 and which is aligned with an opening 1a in the end face of the housing 1. Through the opening 1a, the coupling member 7 of a part to be coupled, in particular a carriage, is inserted, which is to be coupled to the part or carriage to which the housing 1 is fastened. The coupling member 7 has a recess, in particular a notch 7a. If the coupling member 7 is pushed into the housing 1 through the opening 1a, the front wedge-shaped tip of the coupling member 7 rotates a surface of the connecting part 4b which extends into the longitudinal channel 2b, so that the locking bolt 4 is rotated, the control part 3 against the pressure the spring 8 moves. If the coupling member 7 is pushed into its end position, its notch 7a reaches the locking bolt 4 and the connecting part 4b snaps into the notch 7a so that the control part 3 and locking bolt 4 then assume the positions shown in FIG. The coupling member 7 can then no longer be pulled out of the lock by force.

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 end opposite the locking bolt 4, a securing part 5 is mounted vertically displaceably in the interior of the housing 1 and has an inclined surface 5a on its upper side, which comes into contact with a front wedge surface of the coupling member 7 or its tip when the coupling member 7 is inserted. The securing part 5 is thus held downward in its lower position against the pressure of a compression spring 9 lying therein by the coupling member tip.

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 has two further openings 1b and 1c on the end face opposite the opening 1a. A coin can be inserted into the pointed opening 1b as a deposit which, when the securing part 5 is in the lower position, slides over the top of the securing part 5 so far into the housing that it does not, or only slightly, protrude from the outside of the housing. In this most inserted position of the coin M, the coin is gripped by two lateral projections 5a protruding from the upper side of the securing part 5 when the coupling member 7 is at least partially removed and the securing part 5 is in its upper position, see FIG. 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 has on its upper side 2 vertically protruding pins 5b which are so far apart that the coin M can be inserted between them. The pins 5b protrude into a longitudinal channel 10 which opens into the slot-shaped opening 1c. In the opening 1c and the channel 10, a card in particular in the form of a credit card or a key card can be inserted horizontally into the lock, with holes in the card in the end position standing 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 closed in the region of the opening 1c by a locking roller 10 which can be moved through the card and ensures that dirt and dust cannot penetrate into 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 1 a, it is locked in its end position by the locking bolt 4, as described above. In this end position the coupling member 7 presses the securing part 5 into its position releasing the longitudinal channel 10 and the coin channel and the control part 3 is in its position close to the openings 1b and 1c, into 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.If a position M or a card is now inserted into the lock in the position shown in FIG. 1, the coin M presses against the transverse wall 3c or the card against a stroke 3d located far inside on the top of the control part 3. By inserting the Coin or card is thus pushed the control part 3 to the right of the openings 1b and 1c against the pressure of the spring 8 in the position shown in Figure 2. Here, the control part 3 rotates the locking bolt 4 into its releasing position via the slots 3b and the pins 4c, the inner upper side of the connecting part 4b coming out of the notch 7a of the coupling member and assuming a horizontal position. Thus, the connecting part 4b is no longer 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 the coupling member 7 is pulled out, its tip releases the securing part 5 so that it can move upwards and lock the coin and / or the card with the projection 5a and / or the pins 5b. The coin and / or card thus remain held in the deposit lock until the coupling member 7 is inserted again and the securing part 5 is pressed down into the release position by the coupling member 7.

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 exemplary embodiment according to FIGS. 7 and 8 differs from that according to FIGS. 1 to 6 in that the locking bolt is not rotated by the control part but is shifted. The locking bolt 4a is thus displaceable at right angles to the longitudinal axis of the lock and the longitudinal axis of the coupling member in the housing and / or in the bearing block 2 and has a projection 13 which lies in an oblique slot 12 of the control part 3. If the control part 3 is moved by a few millimeters by a coin / card, the locking bolt 4a comes out of the recess of the coupling member and the coupling member is free.
