Definitions
- the invention relates to a deposit lock for transport trolleys, in particular shopping trolleys, which can be inserted into a similar trolley, each trolley being equipped with a deposit lock and a coupling member such that the coupling member of one trolley can be locked in the deposit lock of the next trolley for coupling together in a row of standing wagons or for releasing the wagon standing preferably at the end of the row by entering a deposit mark, the deposit lock containing a lock mechanism which locks the entered deposit mark when the goods are released and which releases them when the carriage is recoupled.
- Such deposit locks are known from DE-A 25 54 916 and are now on the market in different embodiments. Since the release of a trolley is only possible by inserting a coin into the deposit lock, and the user only gets the coin back when he reconnects the trolley to one of the various collection points, the trolleys no longer stand around uselessly. You save personnel to search, collect and return the wagons and also manage with fewer wagons because the unused ones are always available at the points of use and do not stand around uselessly on the premises.
- the deposit locks are currently designed so that they can be operated with one-mark or two-mark items, abroad with coins of the respective national currency with a similar value, so that the user has sufficient incentive to return the car to one of the collection points after use.
- plastic chips have been offered as replacements for the deposit coins mentioned, which correspond in size to the respective deposit coin and thus allow the deposit lock to be operated in its place. At the moment, these plastic chips are still largely offered at the price of the coin they can replace.
- the manufacturing cost of the plastic chip is only on the order of a penny; you have to expect that you can soon buy these chips at a much lower price.
- the incentive to return the shopping cart to the collection point after use is then of course barely there and the deposit system largely loses its meaning.
- the object of the present invention is to improve the deposit system described in such a way that its misuse by inferior plastic chips and the like is excluded.
- the object is achieved in that the deposit tag has an additional actuator which, when the carriage is released, directly or indirectly brings about the operative connection between the deposit tag and / or its actuator on the one hand and the lock mechanism on the other.
- the invention therefore begins with the knowledge that it does not work with complex test devices in the deposit lock, but instead changes the deposit mark itself.
- the deposit system is raised to a higher technical level, in which the deposit brand is assigned an additional functional and recognition effect. Misuse by easily manufactured plastic disks or the like is excluded.
- Another advantage of the invention is that in border areas, in which the currency of the neighboring country is usually used, the deposit lock does not need to be equipped with two different coin channels and lock mechanisms, but instead the deposit stamps designed according to the invention can be used.
- the mode of operation of the additional actuator can be different.
- the actuator can be used as a prerequisite to bring the deposit tag into the correct position in the deposit lock, for example by the actuator corresponding to guideways of the deposit lock and thereby holding the deposit tag in a position that is independent of its scope. But it is also possible that the actuator itself in Active connection with the lock mechanism arrives, thus triggers even the release of the neighboring car or the locking of the deposit tag.
- a magnet integrated into the deposit tag or an element that projects or recesses on one or both sides with respect to the outline of the deposit tag, such as a pin, a ball or the like, can be used as the actuator.
- the actuator There is also the possibility of not arranging the actuator fixedly but displaceably in the deposit mark.
- the coin lock 1 is attached in any manner to a shopping cart, not shown.
- a coupling member in the form of a
- the formation of the deposit mark 3 is essential. It has a bore in its center in which a ball 3a is slidably caught.
- the coin shaft 4 has a path curve 4a, the profile of which corresponds to the diameter of the ball 3a. This trajectory is formed at the beginning of the coin shaft 4 as a depression, but runs upward within the deposit lock 1, so that the ball is raised when the deposit mark 3 is inserted from the position shown in broken lines into the position shown in solid lines. As a result, it lifts a locking element 5 arranged above it, which can also be designed as a ball, up to the position drawn with solid lines.
- the locking member 5 is still partially in Engagement with a bore 2a of the key 2, but can no longer lock the key 2 against being pulled out to the right, because only about the lower third of the ball 5 projects into the bore 2a. If the key 2 is pulled outwards or, as is the practice, the shopping cart with the deposit machine 1 is pulled out of the car column to the left, the left edge of the bore 2a presses the ball 5 upwards a little and can then be removed from the key 2 subtracted from.
- the user inserts the key 2 of the last car in the car row into the machine 1.
- the ball 5 is briefly raised until it can slide into the bore 2a and at the same time the locking element 6 is pressed upwards out of the position engaging behind the deposit mark 3.
- the key 2 is temporarily held in this position only by friction in the deposit machine. Due to the raised blocking element 6, the deposit mark 3 can now be removed.
- the space occupied by the actuator 3a below the ball 5 is released, which means that it can slide into its lower, dashed end position and thus locks the key 2 in a form-fitting manner.
- FIG. 2 shows another exemplary embodiment, reference being made only to the action of the actuator arranged on the deposit tag for the sake of simplicity.
- the deposit mark is a practically circular disk 13, which, however, has a cylindrical pin 13a projecting on both sides at its center.
- the pin 13a corresponds to guide surfaces in the form of two grooves 14a of a coin pusher 14, which are arranged on both sides of the deposit mark and are open at the top.
- the deposit mark 13 is kept at an artificially elevated level, with its lower edge a few millimeters above the bottom of the coin pusher or the Coin slot lies.
- the deposit tag can lift a blocking member 15 arranged above out of the blocking position into the position shown in dashed lines, whereby the key 2 is released directly or indirectly.
- the coin slide 14 is locked in the inserted position by a spring-loaded locking element 16 which is mounted in the lock housing in a vertically displaceable manner and also ejects the key or by other locking elements known per se.
- FIG. 3 shows a section of a further alternative, in which the deposit tag 23 has a transversely displaceable pin 23a in its center.
- This pin is not conveyed into the release position like the ball 3a in FIG. 1, but rather consists of a material which responds to magnetic forces, so that it is moved from a position in the coin shaft 24 to a magnet 25 from the position shown in broken lines to the position shown in solid lines is shifted to the right. He works in this position as a stop against an edge 26 in the coin channel, secures the deposit token against falling through and holds it in a release position similar to FIG. 2 in order to unlock a locking member 15, not shown.

Abstract
Description
Die Erfindung betrifft ein Pfandschloß für Transportwagen, insbesondere Einkaufswagen, der in einen gleichartigen Wagen einschiebbar ist, wobei jeder Wagen mit einem Pfandschloß und einem Kopplungsglied ausgerüstet ist, derart, daß das Kopplungsglied des einen Wagens im Pfandschloß des nächsten Wagens verriegelbar ist zum Aneinanderkoppeln von in einer Reihe stehenden Wagen bzw. zur Freigabe des vorzugsweise am Reihenende stehenden Wagens gegen Eingabe einer Pfandmarke, wobei das Pfandschloß einen Schloßmechanismus enthält, der die eingegebene Pfandmarke bei der Warenfreigabe verriegelt und der sie beim Wiederankoppeln des Wagens freigibt.The invention relates to a deposit lock for transport trolleys, in particular shopping trolleys, which can be inserted into a similar trolley, each trolley being equipped with a deposit lock and a coupling member such that the coupling member of one trolley can be locked in the deposit lock of the next trolley for coupling together in a row of standing wagons or for releasing the wagon standing preferably at the end of the row by entering a deposit mark, the deposit lock containing a lock mechanism which locks the entered deposit mark when the goods are released and which releases them when the carriage is recoupled.
Derartige Pfandschlösser sind durch die DE-A 25 54 916 bekannt geworden und inzwischen in unterschiedlichen Ausführungsformen auf dem Markt. Da die Freigabe eines Wagens nur gegen Einstecken einer Münze in das Pfandschloß möglich ist, und der Benutzer die Münze nur dann zurückerhält, wenn er den Wagen an einer der verschiedenen Sammelstellen wieder ankoppelt, stehen die Wagen nicht mehr nutzlos herum. Man spart Personal zum Suchen, Sammeln und Zurückbringen der Wagen und kommt auch mit einer geringeren Wagenzahl aus, weil die nicht benutzten stets an den Bedarfspunkten zur Verfügung gehalten werden und nicht nutzlos auf dem Gelände herumstehen.Such deposit locks are known from DE-A 25 54 916 and are now on the market in different embodiments. Since the release of a trolley is only possible by inserting a coin into the deposit lock, and the user only gets the coin back when he reconnects the trolley to one of the various collection points, the trolleys no longer stand around uselessly. You save personnel to search, collect and return the wagons and also manage with fewer wagons because the unused ones are always available at the points of use and do not stand around uselessly on the premises.
Derzeit sind die Pfandschlösser so ausgebildet, daß sie mit Einmark- oder Zweimark-Stücken, im Ausland mit Münzen der jeweiligen Landeswährung mit ähnlichem Wert betrieben werden, damit der Benutzer hinreichenden Anreiz hat, den Wagen nach Gebrauch wieder zu einem der Sammelpunkte zurückzubringen.The deposit locks are currently designed so that they can be operated with one-mark or two-mark items, abroad with coins of the respective national currency with a similar value, so that the user has sufficient incentive to return the car to one of the collection points after use.
In jüngster Zeit werden als Ersatz für die genannten Pfandmünzen Plastikchips angeboten, die in ihrer Größe der jweiligen Pfandmünze entsprechen und somit an deren Stelle die Betätigung des Pfandschloses gestatten. Momentan werden diese Kunststoffchips noch weitgehend zum Preis der durch sie ersetzbaren Münze angeboten. Die Herstellungskosten des Plastikchips liegen aber nur in der Größenordnung eines Pfennigs; man muß also damit rechnen, daß man diese Chips bald zu einem viel geringeren Preis erwerben kann. Der Anreiz, den Einkaufswagen nach Gebrauch wieder zur Sammelstelle zurückzubringen, ist dann natürlich kaum noch gegeben und das Pfandsystem verliert weitgehend seinen Sinn.Recently, plastic chips have been offered as replacements for the deposit coins mentioned, which correspond in size to the respective deposit coin and thus allow the deposit lock to be operated in its place. At the moment, these plastic chips are still largely offered at the price of the coin they can replace. The manufacturing cost of the plastic chip is only on the order of a penny; you have to expect that you can soon buy these chips at a much lower price. The incentive to return the shopping cart to the collection point after use is then of course barely there and the deposit system largely loses its meaning.
Hiervon ausgehend liegt die Aufgabe der vorliegenden Erfindung darin, das beschriebene Pfandsystem dahingehend zu verbessern, daß sein Mißbrauch durch minderwertige Kunststoffchips und der gleichen ausgeschlossen wird.Proceeding from this, the object of the present invention is to improve the deposit system described in such a way that its misuse by inferior plastic chips and the like is excluded.
Seitens der Anmelderin ist zunächst daran gedacht worden, den Mißbrauch der Pfandschlösser dadurch zu verhindern, daß man Münzprüfer ähnlich wie in Warenverkaufsautomaten einbaut, die nicht nur den Durchmesser der Münze abtasten sondern auch beispielsweise ihr Gewicht, ihre Dicke oder dergleichen. Dadurch wird aber der Preis des Pfandschlosses unwirtschaftlich hoch.On the part of the applicant, the first thought was to prevent the misuse of the deposit locks by installing coin validators similar to that in vending machines, which not only scan the diameter of the coin but also, for example, its weight, its thickness or the like. However, this makes the price of the deposit lock uneconomically high.
Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß die Pfandmarke ein zusätzliches Stellglied aufweist, das bei der Freigabe des Wagens direkt oder indirekt die Wirkverbindung zwischen Pfandmarke und/oder seinem Stellglied einerseits und dem Schloßmechanismus andererseits herbeiführt.According to the invention, the object is achieved in that the deposit tag has an additional actuator which, when the carriage is released, directly or indirectly brings about the operative connection between the deposit tag and / or its actuator on the one hand and the lock mechanism on the other.
Die Erfindung setzt also bei der Erkenntnis an, nicht mit aufwendigen Prüfeinrichtungen im Pfandschloß zu arbeiten, sondern stattdessen die Pfandmarke selbst zu verändern. Das Pfandsystem wird auf ein höheres technisches Niveau gehoben, in dem der Pfandmarke ein zusätzlicher Funktions- und Erkennungseffekt zugeordnet wird. Der Mißbrauch durch einfach herzustellende Plastikscheiben oder dergleichen ist dadurch ausgeschlossen.The invention therefore begins with the knowledge that it does not work with complex test devices in the deposit lock, but instead changes the deposit mark itself. The deposit system is raised to a higher technical level, in which the deposit brand is assigned an additional functional and recognition effect. Misuse by easily manufactured plastic disks or the like is excluded.
Ein weiterer Vorteil der Erfindung besteht darin, daß in Grenzgebieten, in denen meist auch die Währung des Nachbarlandes verwendet wird, das Pfandschloß nicht mit zwei unterschiedlichen Münzkanälen und Schloßmechanismen ausgerüstet zu werden braucht sondern stattdessen die erfindungsgemäß ausgebildeten Pfandmarken eingesetzt werden können.Another advantage of the invention is that in border areas, in which the currency of the neighboring country is usually used, the deposit lock does not need to be equipped with two different coin channels and lock mechanisms, but instead the deposit stamps designed according to the invention can be used.
Die Wirkungsweise des zusätzlichen Stellgliedes kann unterschiedlich sein. Zum einen kann das Stellglied als Voraussetzung verwendet werden, um die Pfandmarke überhaupt in die richtige Position im Pfandschloß zu bringen, etwa indem das Stellglied mit Führungsbahnen des Pfandschlosses korrespondiert und die Pfandmarke dadurch in einer von ihrem Umfang unabhängigen Position hält. Ebenso ist es aber auch möglich, daß das Stellglied selbst in Wirkverbindung mit dem Schloßmechanismus gelangt, also selbst die Freigabe des Nachbarwagens bzw. das Verriegeln der Pfandmarke auslöst.The mode of operation of the additional actuator can be different. On the one hand, the actuator can be used as a prerequisite to bring the deposit tag into the correct position in the deposit lock, for example by the actuator corresponding to guideways of the deposit lock and thereby holding the deposit tag in a position that is independent of its scope. But it is also possible that the actuator itself in Active connection with the lock mechanism arrives, thus triggers even the release of the neighboring car or the locking of the deposit tag.
Für die Ausbildung des Stellgliedes bestehen ebenfalls unterschiedliche Möglichkeiten. So kann als Stellglied ein in die Pfandmarke integrierter Magnet oder aber ein gegenüber dem Umriß der Pfandmarke ein- oder beidseits vorspringendes oder zurückspringendes Element, etwa ein Stift, eine Kugel oder dergleichen verwendet werden. Auch besteht die Möglickeit, das Stellglied nicht fest sondern verschiebbar in der Pfandmarke anzuordnen.There are also different options for training the actuator. Thus, a magnet integrated into the deposit tag or an element that projects or recesses on one or both sides with respect to the outline of the deposit tag, such as a pin, a ball or the like, can be used as the actuator. There is also the possibility of not arranging the actuator fixedly but displaceably in the deposit mark.
Auch liegt es im Rahmen der Erfindung, das Stellglied allein durch individuelle Oberflächengestaltung der Pfandmarke zu realisieren, etwa durch spezielle Erhebungen, Nuten oder Schlitze und dergleichen.It is also within the scope of the invention to implement the actuator solely by means of individual surface design of the deposit mark, for example by means of special elevations, grooves or slots and the like.

In Figur 1 ist das Münzschloß 1 in beliebiger Weise an einem nicht dargestellten Einkaufswagen befestigt. In dem Schloß 1 steckt ein Kopplungsglied in Form einesIn Figure 1, the coin lock 1 is attached in any manner to a shopping cart, not shown. In the lock 1 is a coupling member in the form of a
Schlüssels 2 eines in der Wagenkolonne davor stehenden, ebenfalls nicht gezeigten Einkaufswagens. Soll der Wagen mit dem Pfandautomat 1 abgekoppelt werden, so muß eine Pfandmarke 3 in den Automat eingeschoben werden. Sie bewirkt über einen an sich bekannten Schloßmechanismus, auf den später noch eingegangen wird, daß einerseits der Schlüssel 2 freigegeben, der Wagen mit dem Pfandschloß 1 also weggefahren werden kann, und daß andererseits gleichzeitig die Pfandmarke 3 im Pfandautomat 1 verriegelt wird.Key 2 of a shopping cart standing in front of it in the car column, also not shown. If the car is to be uncoupled from the deposit machine 1, a deposit tag 3 must be inserted into the machine. It causes a lock mechanism known per se, which will be discussed later that on the one hand the key 2 is released, the carriage with the deposit lock 1 can thus be moved away, and on the other hand the deposit tag 3 is locked in the deposit machine 1 at the same time.
Für die konstruktive Ausbildung des Schloßmechanismus sind eine Fülle von Bauformen auf dem Markt. Daher wird der Schloßmechanismus nur anhand eines Ausführungsbeispieles in Figur 1 beschrieben. Bei den übrigen Figuren sind ähnliche Konstruktionen mit dem gleichen Prinzip geeignet.There is an abundance of designs on the market for the design of the lock mechanism. The lock mechanism is therefore only described with reference to an exemplary embodiment in FIG. 1. Similar constructions with the same principle are suitable for the other figures.
Wesentlich ist die Ausbildung der Pfandmarke 3. Sie weist in ihrem Zentrum eine Bohrung auf, in der eine Kugel 3a verschiebbar gefangen ist. Zur Führung der Kugel 3a weist der Münzschacht 4 eine Bahnkurve 4a auf, deren Profil mit dem Durchmesser der Kugel 3a korrespondiert. Diese Bahnkurve ist am Beginn des Münzschachtes 4 als Vertiefung ausgebildet, läuft aber innerhalb des Pfandschlosses 1 nach oben, so daß die Kugel beim Einschieben der Pfandmarke 3 aus der gestrichelt gezeichneten Position in die mit durchgezogenen Linien gezeichnete Position angehoben wird. Sie hebt dadurch ein über ihr angeordnetes Sperrglied 5, das ebenfalls als Kugel ausgebildet sein kann, hoch in die mit durchgezogenen Linien gezeichnete Position. Das Sperrglied 5 steht dabei zwar noch teilwese in Eingriff mit einer Bohrung 2a des Schlüssels 2, vermag den Schlüssel 2 aber nicht mehr gegen ein Herausziehen nach rechts zu arretieren, weil nur noch etwa das untere Drittel der Kugel 5 in die Bohrung 2a hineinragt. Wird also der Schlüssel 2 nach außen gezogen oder, wie es der Praxis entspricht, der Einkaufswagen mit dem Pfandautomat 1 nach links aus der Wagenkolonne herausgezogen, so drückt der linke Rand der Bohrung 2a die Kugel 5 noch etwas nach oben und kann dann vom Schlüssel 2 abgezogen werden.The formation of the deposit mark 3 is essential. It has a bore in its center in which a ball 3a is slidably caught. To guide the ball 3a, the coin shaft 4 has a path curve 4a, the profile of which corresponds to the diameter of the ball 3a. This trajectory is formed at the beginning of the coin shaft 4 as a depression, but runs upward within the deposit lock 1, so that the ball is raised when the deposit mark 3 is inserted from the position shown in broken lines into the position shown in solid lines. As a result, it lifts a
Gleichzeitig entfällt aber die Wirkverbindung zwischen dem Schlüssel 2 und einem Sperrelement 6. Dadurch gelangt das Sperrelement 6 nach unten in die gestrichelt gezeichnete Position und hintergreift mit seinem Fortsatz 6a die Pfandmarke 3 an ihrem Umfang. Die Pfandmarke 3 kann daher nicht mehr aus dem Pfandschloß entnommen werden.At the same time, however, there is no operative connection between the key 2 and a locking element 6. As a result, the locking element 6 moves down into the position shown in dashed lines and engages behind the deposit tag 3 on its circumference with its
Wenn der Wagen nach Ausgebrauch wieder an einer Sammelstelle angekoppelt werden soll, schiebt der Benutzer den Schlüssel 2 des in der Wagenreihe letzten Wagens in den Automat 1 ein. Die Kugel 5 wird dabei kurz angehoben, bis sie in die Bohrung 2a hineinrutschen kann und gleichzeitig wird das Sperrelement 6 aus der die Pfandmarke 3 hintergreifenden Position heraus nach oben gedrückt. Der Schlüssel 2 ist in dieser Position vorläufig nur durch Reibschluß im Pfandautomat gehalten. Durch das angehobene Sperrelement 6 kann jetzt aber die Pfandmarke 3 entnommen werden. Dabei wird der vom Stellglied 3a beanspruchte Raum unterhalb der Kugel 5 freigegeben, diese kann also in ihre untere, gestrichelt gezeichnete Endlage rutschen und arretiert somit formschlüssig den Schlüssel 2.If the car is to be coupled to a collection point again after use, the user inserts the key 2 of the last car in the car row into the machine 1. The
Figur 2 zeigt ein anderes Ausführungsbeispiel, wobei der Einfachheit halber nur noch auf die Einwirkung des an der Pfandmarke angeordneten Stellgliedes Bezug genommen wird. Als Pfandmarke dient hier wie im vorangegangenen Fall eine praktisch kreisförmige Scheibe 13, die jedoch in ihrem Zentrum einen beidseits vorstehenden zylindrischen Stift 13a aufweist. Der Stift 13a korrespondiert mit Führungsflächen in Form zweier beidseits der Pfandmarke angeordneter, nach oben offener Nuten 14a eines Münzschiebers 14. Dadurch wird die Pfandmarke 13 auf einem künstlich erhöhten Niveau gehalten, bei dem ihr unterer Rand einige Millimeter oberhalb des Bodens des Münzschiebers bzw. des Münzschachtes liegt. Auf diese Weise vermag die Pfandmarke ein oberhalb angeordnetes Sperrglied 15 aus der Sperrstellung heraus in die gestrichelt gezeichnete Position anzuheben, wodurch der Schlüssel 2 direkt oder indirekt freigegeben wird. Die Arretierung des Münzschiebers 14 in der eingeschobenen Stellung erfolgt durch ein gefedertes Sperrelement 16, das im Schloßgehäuse vertikal verschiebbar gelagert ist und auch den Schlüssel auswirft oder durch andere an sich bekannte Sperrelemente.FIG. 2 shows another exemplary embodiment, reference being made only to the action of the actuator arranged on the deposit tag for the sake of simplicity. As in the previous case, the deposit mark is a practically
Figur 3 zeigt einen Ausschnitt einer weiteren Alternative, bei der die Pfandmarke 23 in ihrem Zentrum einen quer verschiebbaren Stift 23a aufweist. Dieser Stift wird nicht wie die Kugel 3a in Figur 1 in die Auslöseposition befördert, sondern er besteht aus einem auf Magnetkräfte ansprechenden Werkstoff, so daß er von einem in den Münzschacht 24 eingebauten Magnet 25 aus der gestrichelt dargestellten Position in die mit ausgezogenen Linien gezeigte Position nach rechts verschoben wird. Er wirkt in dieser Stellung als Anschlag gegenüber einer Kante 26 im Münzkanal, sichert die Pfandmarke gegen ein Durchfallen und hält sie in einer Auslöseposition ähnlich Fig. 2, um ein nicht gezeigtes Sperrglied 15 zu entsperren.FIG. 3 shows a section of a further alternative, in which the
