Description

Die Erfindung betrifft eine pfandmünzenbetätigte Kupplungsvorrichtung für über diese Vorrichtung in einer Reihe miteinander verbindbare Gegenstände, insbesondere Einkaufswagen, mit den Merkmalen des ersten Teiles des Patentanspruches 1.The invention relates to a coin operated coupling device for objects that can be connected to one another in a row, in particular shopping carts, with the features of the first part of patent claim 1.

Solche Vorrichtungen sind bekannt, um in Geschäften oder öffentlichen Einrichtungen gebrauchte Einkaufswagen abzuschließen und den Benutzer dazu anzuhalten, seinen Wagen nach Gebrauch wieder in eine Reihe zu stellen. Diese bekannten Vorrichtungen, seien sie rein mechanisch oder elektromechanisch, sind konstruktiv aufwendig, groß bauend, nicht ausreichend zuverlässig und von hohem Gewicht.Such devices are known to lock shopping carts used in shops or public facilities and to encourage the user to put his cart back in line after use. These known devices, be they purely mechanical or electromechanical, are structurally complex, large, not sufficiently reliable and of high weight.

Aus der DE-A-27 25 530 ist eine pfandmünzenbetätigte Kupplungsvorrichtung der eingangs genannten Art bekannt. Bei dieser bekannten Vorrichtung wird das Ende des Kupplungselementes durch ein eine Ringnut aufweisendes zylinderförmiges Element gebildet. Durch diese Ausführung des Kupplungselementendes ist es jedoch nicht möglich, unterschiedliche Kupplungsvorrichtungen voneinander zu unterscheiden, so daß Einkaufswagen verschiedener Geschäfte in einer Einkaufswagenkette miteinander vermischt werden können.From DE-A-27 25 530 a coin operated clutch device of the type mentioned is known. In this known device, the end of the coupling element is formed by a cylindrical element having an annular groove. With this design of the coupling element end, however, it is not possible to distinguish different coupling devices from one another, so that shopping trolleys from different shops can be mixed together in a shopping trolley chain.

Daher liegt der Erfindung die Aufgabe zugrunde, bei einer Vorrichtung der eingangs genannten Art unterschiedlichen Einkaufswagen zugeordnete Kupplungselemente voneinander unterscheiden zu können.It is therefore the object of the invention to be able to distinguish between coupling elements assigned to different shopping carts in a device of the type mentioned in the introduction.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of patent claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen aufgeführt.Advantageous embodiments of the invention are listed in the dependent claims.

In einem Ausführungsbeispiel kann die Vorrichtung an Münzen verschiedenen Durchmessers leicht angepaßt und es können Störungen einfach beseitigt werden. Auch kann die Vorrichtung so ausgeführt sein, daß die Abtasthebel keine direkte Wirkung auf die Verriegelung des Stegs ausüben, was deren leichten Austausch für eine Anpassung an verschiedene Münzgrößen zuläßt. Außerdem ist ein zum Gleitstück zusätzlich angeordneter Schließstab nicht unbedingt notwendig, was die Vorrichtung beträchtlich vereinfacht.In one embodiment, the device can be easily adapted to coins of different diameters and faults can be easily eliminated. The device can also be designed so that the scanning levers have no direct effect on the locking of the web, which allows their easy replacement for adaptation to different coin sizes. In addition, a locking rod arranged in addition to the slide is not absolutely necessary, which considerably simplifies the device.

Die Vorrichtung enthält ein Trägergehäuse 1 mit einem Einlaßplättchen 2 für eine Münze 18, das vor der Münzaufnahmekammer befestigt ist. Hinter dem Plättchen 2 befindet sich in der Kammer eine längliche waagerechte Auswertvorrichtung 3, in Auswertrichtung beaufschlagt durch eine Auswerterfeder 4. Zwischen Plättchen 2 und Auswertrichtung 3 ist für die Münze eine seitliche Klemmbacke 5 befestigt, die durch eine Klemmbackenfeder 6 (Abb. 3) verschiebbar ist. Zwei zweiarmige Schwinghebel 7 und 8, beidseitig durch Haltefedern 9 und 10 zurückgezogen, enden neben dem Plättchen 2 mit beidseitigen Führungsrollen 11 und 12 und drehen sich um einen Achsbolzen 13. Die freien Enden von Auswertvorrichtung 3, Schwinghebeln 7, 8 und Klemmbacke 5 ragen in die Kammer hinein.The device contains a carrier housing 1 with an inlet plate 2 for a coin 18, which is attached in front of the coin receiving chamber. Behind the plate 2 there is an elongated horizontal evaluation device 3 in the chamber, acted upon in the evaluation direction by an evaluation spring 4. Between the plate 2 and the evaluation direction 3, a lateral clamping jaw 5 is fastened for the coin, which can be displaced by a clamping jaw spring 6 (Fig. 3) is. Two two-armed rocker arms 7 and 8, retracted on both sides by retaining springs 9 and 10, end next to the plate 2 with guide rollers 11 and 12 on both sides and rotate about an axle bolt 13. The free ends of the evaluation device 3, rocker arms 7, 8 and clamping jaw 5 protrude into the chamber inside.

Das Gehäuse 1 hat unter dem Plättchen 2 und der Kammer eine Aussparung 1a, in die eine Schaltsperrklinke 14 von oben hineinragt, die zur Aussparung 14a hin durch eine Feder 15 durch Druck steht. Der Schwinghebel 7 ist an einem Schließschieber 16, der Schwinghebel 8 an einem Schließschieber 17 mit dem der Münze 18 gegenüberliegenden Ende gelenkig befestigt.The housing 1 has under the plate 2 and the chamber a recess 1a, into which a switching pawl 14 projects from above, which is pressed towards the recess 14a by a spring 15. The rocker arm 7 is articulated to a closing slide 16, the rocking lever 8 to a closing slide 17 with the end opposite the coin 18.

Das dem Plättchen 2 gegenüberliegende Ende 19 der Auswertvorrichtung 3 hat eine Einrastkerbe für einen Riegel 20, der durch eine Riegelfeder 21 zur Vorrichtung 3 hin beaufschlagt ist. Diese Einrastung vollzieht sich durch Eingabe der Münze 18, die die Auswertvorrichtung 3 gegen die Wirkung ihrer Auswerterfeder 4 hineinschiebt. Ohne die Münze verriegeln die Schließschieber 16 und 17 einen unter Einwirkung einer Schließstabfeder 23 stehenden Schließstab 22 durch Zusammenwirken eines Durchbruchs des Schließschiebers 16 mit einer rechteckigen Aussparung 24 des Schließstabs 22 und durch die Sperrstellung des Schließschiebers 17 vor dem Stab 22.The end 19 of the evaluation device 3 opposite the plate 2 has a latching notch for a bolt 20 which is acted upon by a locking spring 21 towards the device 3. This engagement takes place by entering the coin 18 which pushes the evaluation device 3 in against the action of its evaluation spring 4. Without the coin, the locking slides 16 and 17 lock a locking bar 22 under the action of a locking bar spring 23 by the interaction of an opening in the locking bar 16 with a rectangular recess 24 in the locking bar 22 and by the locking position of the locking slide 17 in front of the bar 22.

Ein Zentralriegel 25 mit Federzug wirkt mit einer rechteckigen Aussparung des Schließstabs 22 zusammen und wird gegen die Einwirkung seiner Feder durch eine rampenförmige Schrägfläche der Auswertvorrichtung 3 versetzt. Ein Druckversuch auf die Auswertvorrichtung 3 ohne Schwenken des Schwinghebels 7 läßt kein Versetzen der Auswertvorrichtung 3 zu, die durch ihren Absatz 26 gegen den Schließschieber 16 blockiert wird.A central bolt 25 with spring action interacts with a rectangular recess in the locking bar 22 and is countered by the action of its spring by a ramp-shaped incline Surface of the evaluation device 3 offset. A pressure test on the evaluation device 3 without swiveling the rocking lever 7 does not permit displacement of the evaluation device 3, which is blocked by the shoulder 26 against the closing slide 16.

Die Auswertvorrichtung endet zur Münze hin mit einer Öffnung 27, so daß die Eingabe einer zu kleinen Münze, gefolgt von einer anderen Münze, ein Lösen der Auswertvorrichtung 3 nicht zulassen. Diese Maßnahmen sind vorgesehen, um unerwünschte Blockierungen zu vermeiden. Außerdem stößt ein Druck mit einem Werkzeug in den zentralen Teil der Auswertrichtung 3 gegen den festen Teil 28 des Gehäuses.The evaluation device ends towards the coin with an opening 27, so that the input of a coin that is too small, followed by another coin, does not allow the evaluation device 3 to be released. These measures are provided to avoid unwanted blockages. In addition, pressure with a tool strikes the central part of the evaluation direction 3 against the fixed part 28 of the housing.

Der rückwärtige Teil des Gehäuses 1 bildet einen Vorsprung 1 mit einmontiertem Schwenkhebel 29, der sich um einen Achsbolzen 30 dreht und dessen eines Ende mit dem Ende des Schließstabs 22 zusammenarbeitet. Ein längliches Kupplungselement in Form eines Gleitstößels 31 ist in Längsrichtung durch eine Gleitstößelfeder 32 beaufschlagt und bildet einen Vorsprung 33 aus. Ein Eingeben einer Münze 18 (Abb. 2) bewirkt ein Lösen des Schließstabs 22, und ein (mechanischer) Zug in Richtung S bewirkt ein Drehen des Schwenkhebels 29 insofern, daß das vom Schließstab 22 abgewandte Ende des Schwenkhebels 29 gegen einen Absatz 1c' in der Aussparung 1a' einer bisher an der Vorrichtung verriegelten identischen Vorrichtung anschlägt. Gleichzeitig gleitet der Gleitstößel 31 unter Einwirkung seiner Gleitstößelfeder 32 (Abb. 4) nach rechts und der Vorsprung 33 blockiert den Schwenkhebel 29 in der entriegelten Position.The rear part of the housing 1 forms a projection 1 with an installed pivot lever 29 which rotates about an axle bolt 30 and one end of which cooperates with the end of the locking rod 22. An elongated coupling element in the form of a slide tappet 31 is acted upon in the longitudinal direction by a slide tappet spring 32 and forms a projection 33. Entering a coin 18 (Fig. 2) causes the locking rod 22 to be released, and a (mechanical) pull in the S direction causes the pivoting lever 29 to rotate in such a way that the end of the pivoting lever 29 facing away from the locking rod 22 abuts a shoulder 1c 'in of the recess 1a 'of an identical device previously locked on the device. At the same time, the slide tappet 31 slides to the right under the action of its slide tappet spring 32 (FIG. 4) and the projection 33 blocks the pivot lever 29 in the unlocked position.

Der Gleitstößel 31 endet an seinem dem Schwenkhebel 29 abgewandten Ende in einem Kupplungselementende 34 in Funktion und Art eines Schlüsselschaftes, insbesondere eines Flachschlüssels. Der Gleitstößel 31 trägt an dem dem Schlüsselschaft 34 gegenüberliegenden Ende benachbart zum Schwenkhebel 29 eine als axial beweglicher Gleitzylinder ausgebildete Sperrvorrichtung 35. In dem Gleitzylinder können sich Plättchenzuhaltungen 36 quer zur Achse bewegen. Die Achse des Gleitzylinders 35, in deren Richtung der Gleitzylinder 35 durch den Gleitstößel 31 verschoben wird, liegt in Verlängerung der Längsachse des Kupplungselementes 31. Der Gleitzylinder 35 ist in einer zylindrischen Ausnehmung 40 mit oberen und unteren Aussparungen 37 verschiebbar. Wenn sich die Vorrichtung in der Position gemäß Fig. 4 befindet, steht jede der Zuhaltungen 36 einer Aussparung 37 gegenüber und rastet dort durch die Schwerkraft ein, so daß der Gleitzylinder 35 in seiner Lage verriegelt und das Kupplungselement 31 unbeweglich ist.The sliding plunger 31 ends at its end facing away from the pivoting lever 29 in a coupling element end 34 in the function and type of a key shaft, in particular a flat key. The slide plunger 31 carries at the end opposite the key shaft 34 adjacent to the swivel lever 29 a locking device 35 designed as an axially movable sliding cylinder. In the sliding cylinder, plate tumblers 36 can move transversely to the axis. The axis of the sliding cylinder 35, in the direction of which the sliding cylinder 35 is displaced by the sliding plunger 31, lies in the extension of the longitudinal axis of the coupling element 31. The sliding cylinder 35 is displaceable in a cylindrical recess 40 with upper and lower recesses 37. When the device is in the position shown in FIG. 4, each of the tumblers 36 faces a recess 37 and engages there by gravity, so that the sliding cylinder 35 locks in position and the coupling element 31 is immovable.

Ein Einführen des Kupplungselementendes 34' einer vorhergehenden Vorrichtung in den (Schlüssel-) Längskanal des Gleitzylinders 35 bewirkt das Heben der Zuhaltungen 36 und die Entriegelung des Gleitzylinders 35. Gegen die Kraft der Gleitstößelfeder 32 wird der Gleitstößel 31 nach links geschoben und der Anschlag des Elementendes 34' bewirkt ein Verschieben des Gleitzylinders 35 und des Gleitstößels 31. Während dieses Vorgangs verschiebt eine Sperrklinke 38 am Gleitstößel 31 den Riegel 20, der die Auswertvorrichtung 3 löst, und der Vorsprung 33 des Gleitstößels 31 gibt den Schwenkhebel 29 frei.An insertion of the coupling element end 34 'of a previous device into the (key) longitudinal channel of the sliding cylinder 35 causes the tumblers 36 to be lifted and the sliding cylinder 35 to be unlocked. The sliding plunger 31 is pushed to the left against the force of the sliding plunger spring 32 and the element end stops 34 'causes the sliding cylinder 35 and the sliding plunger 31 to move. During this process, a pawl 38 on the sliding plunger 31 moves the bolt 20, which releases the evaluation device 3, and the projection 33 of the sliding plunger 31 releases the pivot lever 29.

Geschoben durch den Schließstab 22 und seine Schließstabfeder 23 kann dieses wieder seine verriegelte Position einnehmen (Fig. 2), sobald die Vorrichtung in der vorhergehenden eintaucht. Die Vorrichtung ist dann also durch eine Schaltsperrklinke 14' und deren Klinkenfeder 15' an der vorhergehenden Vorrichtung fixiert, so daß ein Druck auf den Schwenkhebel 29 während der Eingabe der Münze vermieden wird. Wenn der Schließstab 22 ebenfalls seine verriegelte Position wieder eingenommen hat, sind die Schließschieber 16 und 17 gelöst und die Münze 18, geschoben durch die Auswertvorrichtung 3, deren Feder stärker ist als die Rückzugfedern der Schieber 16, 17, wird zurückgeschoben, wird aber durch die Klemmbacke 5, gedrückt durch die Klemmbackenfeder 6, festgehalten.Pushed by the locking bar 22 and its locking bar spring 23, this can assume its locked position again (FIG. 2) as soon as the device is immersed in the previous one. The device is then fixed by a switching pawl 14 'and its pawl spring 15' to the previous device, so that pressure on the pivot lever 29 is avoided while the coin is being inserted. When the locking rod 22 has also returned to its locked position, the closing slides 16 and 17 are released and the coin 18, pushed by the evaluation device 3, the spring of which is stronger than the return springs of the slides 16, 17, is pushed back, but is pushed back by the Jaw 5, pressed by the jaw spring 6, held.

Die Konstruktion bewirkt, daß ein Anschließen bzw. Verriegeln nur an einer identischen Vorrichtung möglich ist, die ihrerseits schon auf einer dritten Vorrichtung oder auf einem wie eine solche Vorrichtung arbeitenden Abschlußträger verriegelt ist. Will man die Vorrichtung an eine zweite anschalten, die nicht ihrerseits an eine dritte identische Vorrichtung angeschaltet ist, befindet sich das Kupplungselement 31 der einen Vorrichtung in der Stellung, wie in Fig. 4 gezeigt, und die Einführung des Kupplungselementendes 34' der vorhergehenden Vorrichtung in den Gleitzylinder 35 bewirkt kein Verschieben des Gleitstö- ßeis 31.The construction means that a connection or locking is only possible on an identical device, which in turn is already locked on a third device or on an end carrier working like such a device. If the device is to be switched on to a second device, which in turn is not connected to a third identical device, the coupling element 31 of the one device is in the position as shown in FIG. 4 and the insertion of the coupling element end 34 'of the previous device in FIG the sliding cylinder 35 does not cause the sliding ice 31 to move.

Die erfindungsgemäße Vorrichtung ist sehr flach und steht folglich nur wenig vor. Wird sie zum Beispiel auf einen Wagen, insbesondere Einkaufswagen, montiert, so kann dies seitlich oder oben geschehen.The device according to the invention is very flat and consequently protrudes only slightly. If, for example, it is mounted on a trolley, in particular a shopping trolley, this can be done on the side or on the top.

Man kann vorsehen, daß mit Hilfe eines (nicht abgebildeten) Schlüssels, der in das Gehäuse 1 eingeführt wird, die Schließschieber 16, 17 und der Zentralriegel 25 wieder ausgerichtet werden können, um den Schließstab 22 und den Schwenkhebel 29 im Falle eines anormalen Blockierens des Systems zu lösen.It can be provided that with the aid of a key (not shown) which is inserted into the housing 1, the locking slides 16, 17 and the central bolt 25 can be realigned to the locking rod 22 and the pivot lever 29 in the event of an abnormal blocking of the System to solve.

Ebenso kann man ein (nicht abgebildetes) Element zum Abkuppeln des Schwenkhebels 29 vom Schließstab 22 vorsehen, um eine defekte Vorrichtung zur Reparatur zu lösen.It is also possible to provide an element (not shown) for uncoupling the pivot lever 29 from the locking bar 22 in order to solve a defective device for repair.

Im folgenden wird das in den Figuren 5 bis 10 gezeigte zweite Ausführungsbeispiel beschrieben. Die zwei Schwinghebel 7 und 8 werden beidseitig durch Haltefedern 9 und 10 zurückgezogen und enden neben den Plättchen 2 mit beidseitigen vorstehenden Führungen 11 und 12.The second exemplary embodiment shown in FIGS. 5 to 10 is described below. The two rocker arms 7 and 8 are retracted on both sides by retaining springs 9 and 10 and end next to the plates 2 with protruding guides 11 and 12 on both sides.

Das vom Plättchen 2 abgewandte Ende 19 der Auswertvorrichtung 3 hat eine Rastnase unter einem Schließschieber 16, auf den eine Schließschieberfeder 51 einwirkt. Dieser Einratvorgang vollzieht sich durch Eingabe der Münze 18 (siehe Fig. 6), die die Auswertvorrichtung 3 gegen die Wirkung ihrer Auswerterfeder 4 schiebt.The end 19 of the evaluation device 3 facing away from the plate 2 has a latching lug under a closing slide 16, on which a closing slide spring 51 acts. This guessing process takes place by entering the coin 18 (see Fig. 6), which pushes the evaluation device 3 against the action of its evaluation spring 4.

Ohne die Münze 18 (Fig. 5) ist der Schließschieber 16 in einer rechteckigen Aussparung 50 des Gleitstößels 31 versenkt, der durch die Gleitstößelfeder 32 vorgespannt ist. Der Schließschieber 16 sperrt den Gleitstößel 31. Der Gleitstößel 31 ist wiederum in Richtung auf die Aussparung 1a des Gehäuses 1 durch ein Kupplungselementende 34 mit Funktion eines Schlüssels verlängert, der mit dem Gleitstößel 31 verschoben wird.Without the coin 18 (FIG. 5), the closing slide 16 is sunk in a rectangular recess 50 of the slide plunger 31, which is prestressed by the slide plunger spring 32. The closing slide 16 locks the slide plunger 31. The slide plunger 31 is in turn extended in the direction of the recess 1a of the housing 1 by a coupling element end 34 with the function of a key which is moved with the slide plunger 31.

An seinem gegenüberliegenden Ende hat der Gleitstößel 31 ebenfalls ein zylindrisches Sperrelement 35 mit Funktion eines Schließzylinders, in dem Zuhaltungen 36 quer gleiten. Der Gleitzylinder 35 ist in einer Bohrung 40 mit Aussparungen 37 gelagert. Wenn die Vorrichtung wie in der Position von Fig. 7 nach Eingabe der Münze gelöst ist, steht jede der Zuhaltungen 36 einer Ausnehmung 37 gegenüber und rastet dort durch die Schwerkraft ein, so daß der Gleitzylinder 35 in seiner Lagerung verriegelt und der Gleitstößel 31 unbeweglich ist.At its opposite end, the slide plunger 31 also has a cylindrical locking element 35 with the function of a locking cylinder in which tumblers 36 slide transversely. The sliding cylinder 35 is mounted in a bore 40 with recesses 37. When the device is released as in the position of FIG. 7 after the coin has been inserted, each of the tumblers 36 faces a recess 37 and engages there by gravity, so that the sliding cylinder 35 locks in its bearing and the sliding plunger 31 is immovable .

Die Vorrichtung umfaßt auch einen der Wirkung einer Riegelfeder 21 unterliegenden Riegel 20, der bei Verriegelungsposition (Fig. 5) sich auf das Ende 19 der Auswertvorrichtung 3 Druck abstützt. Während der Eingabe der Münze 18 hat eine Abschrägung 52 der Auswertvorrichtung 3 den Riegel 20 gegen die Wirkung der Feder 21 zurückgeschoben, und am Ende dieses Vorgangs ist der Riegel 20 federnd in einer rechteckigen Aussparung 53 der Auswertvorrichtung 3 gelagert, die so gegen die Wirkung ihrer Auswerterfeder 4 verriegelt ist (Fig. 6).The device also includes a bar 20, which is subject to the action of a bar spring 21 and, in the locked position (FIG. 5), is supported on the end 19 of the evaluation device 3 by pressure. During the insertion of the coin 18, a bevel 52 of the evaluation device 3 has pushed the bolt 20 back against the action of the spring 21, and at the end of this process the bolt 20 is resiliently mounted in a rectangular recess 53 of the evaluation device 3, which thus counteracts the action of it Evaluation spring 4 is locked (Fig. 6).

Die Einführung des Kupplungselementendes 34' der vorhergehenden Vorrichtung in den Gleitzylinder 35 einer Vorrichtung in der Position wie in Fig. 7 bewirkt das Sichheben der Zuhaltungen 36 und die Entriegelung des Gleitzylinders 35. Der Gleitstößel 31 wird mit dem Gleitzylinder 35 durch das Kupplungselementende 34 nach links geschoben. Während dieses Vorgangs verschiebt eine Sperrklinke 38 am Gleitstößel 31 den Riegel 20 gegen die Wirkung der Riegelfeder 21 nach unten, was die Auswertvorrichtung 3 löst, die unter Einwirkung ihrer Auswerterfeder 4 die Münze 18 erneut nach außen drückt, welche die Führungen 11 und 12 spreizt und das Drehen der Schwinghebei 7 und 8 verursacht. Die Münze 18 wird ausgestoßen, und der Apparat befindet sich im Zustand der Vierriegelung wie in Fig. 5.The introduction of the coupling element end 34 'of the preceding device into the sliding cylinder 35 of a device in the position as in FIG. 7 causes the tumblers 36 to lift and the sliding cylinder 35 to be unlocked. The sliding plunger 31 is moved to the left with the sliding cylinder 35 by the coupling element end 34 pushed. During this process, a pawl 38 on the slide plunger 31 moves the bolt 20 against the action of the locking spring 21 downward, which releases the evaluation device 3, which, under the action of its evaluation spring 4, pushes the coin 18 outward again, which spreads the guides 11 and 12 and causes the swinging levers 7 and 8 to rotate. The coin 18 is ejected and the apparatus is in the four-lock state as in FIG. 5.

Die Eingabe der Münze 18 entriegelt den Schließschieber 16, und die Vorrichtung kann beliebig aus einer vorhergehenden Vorrichtung oder einem Träger mit dem Kupplungselementende 34' herausgelöst werden, an der sie angeschlossen war (Fig. 6).Entering the coin 18 unlocks the closing slide 16, and the device can be detached as desired from a previous device or a carrier with the coupling element end 34 'to which it was connected (FIG. 6).

In der Verriegelungsposition nach Fig. 7 ist es unmöglich, den Schlüsselschaft 34 einer Vorrichtung in der gleichen Verriegelungsposition vollständig einzuführen, weil der Schaft 34' nicht ausreichend in die Aussparung 1a' hineinreicht, um in den Gleitzylinder völlig einzudringen. So verhindert man die Bildung von ungeordneten Schlangen.In the locking position shown in FIG. 7, it is impossible to fully insert the key shaft 34 of a device in the same locking position because the shaft 34 'does not extend sufficiently into the recess 1a' to fully penetrate the sliding cylinder. This prevents the formation of disorderly snakes.

Im Fall einer Blockierung der Vorrichtung, während der keine Münze eingeführt werden kann, läßt ein Spalt 54 in der Aussparung 1a die Einführung eines profilierten Schlüssels 55 (Fig. 8) zu, dessen Ende in eine Aussparung des Schließschiebers 16 dringt. Ein Kippen dieses Schlüssels 55 (Fig. 9) hebt den Schließschieber 16 an und läßt es zu, die Vorrichtung zwecks Reparatur abzutrennen.If the device is blocked, during which no coin can be inserted, a gap 54 in the recess 1a permits the introduction of a profiled key 55 (FIG. 8), the end of which penetrates into a recess in the closing slide 16. Tilting this key 55 (FIG. 9) lifts the closing slide 16 and allows the device to be disconnected for repair.

Entsprechend einer Weiterbildung der Erfindung (in Fig. 10 veranschaulicht) sind die Schwinghebel 7 und 8 mit ihren Federn 9 und 10 durch Achsbolzen 13 auf einem unabhängigen Träger 57 gelenkig angebracht, der die Einlaßplatte 2 sowie die Auswertvorrichtung 3 und ihre Auswerterfeder 4 trägt. Dieses Ensemble 58, das eine austauschbare Kassette zur Anpassung an verschiedene Münzdurchmesser zuläßt, ist lösbar in einer Aussparung 59 des Trägergehäuses 1 montiert. Dies erfolgt mittels einer Spezialschraube (nicht dargestellt), die zum Lösen ein spezielles Werkzeug benötigt. Diese Schraube durchstößt eine Vertiefung 60 des Trägers 57 und ein Innengewinde des Trägergehäuses 1. Diese Anordnung läßt neben der Modifikation einer existierenden Vorrichtung die Demontage zur Reparatur zu, und vor allem den Gebrauch einer, vom Ensemble 58 abgesehen, identischen Münzschließvorrichtung für verschiedene Münzen.According to a development of the invention (illustrated in FIG. 10), the rocking levers 7 and 8 with their springs 9 and 10 are articulated by axle bolts 13 on an independent support 57 which carries the inlet plate 2 and the evaluation device 3 and its evaluation spring 4. This ensemble 58, which allows an exchangeable cassette for adaptation to different coin diameters, is detachably mounted in a recess 59 of the carrier housing 1. This is done using a special screw (not shown), which requires a special tool to loosen. This screw penetrates a recess 60 of the carrier 57 and an internal thread of the carrier housing 1. In addition to the modification of an existing device, this arrangement allows disassembly for repair and, above all, the use of an identical coin locking device for different coins, apart from the ensemble 58.
