Description

Transportwagen Dolly
Die Erfindung betrifft einen von Hand bewegbaren Transportwagen, mit einem Pfandschloss und mit wenigstens einer, außerhalb des Pfandschlosses angeordneten, auf elektrische Energie angewiesenen Einrichtung, die über einen Stromkreis durch eine am Transportwagen befindliche Energiequelle mit elektrischer Energie versorgt wird.The invention relates to a hand-movable transport trolley, with a deposit lock and with at least one device, which is arranged outside the deposit lock and is dependent on electrical energy and is supplied with electrical energy via a circuit by an energy source located on the transport trolley.
Es ist bekannt, von Hand bewegbare Transportwagen, z.B. Einkaufswagen, mit Pfandschlössern auszustatten, damit die Transportwagen, etwa in Selbstbedienungsgeschäften, für die Kunden dann zur Verfügung stehen, wenn diese zuerst ein Pfand in das Pfandschloss eingebracht haben, um den Transportwagen von einer Schlange aneinandergekoppelter Transportwagen lösen zu können. Derart gestaltete Transportwagen sind beispielsweise in der EP 0 199 274B1 näher beschrieben und lassen sich mit einer Informationseinrichtung ausstatten, wie diese z.B. in der EP 0 254 170 vorgeschlagen wird. Die Informationseinrichtung ist mit elektronischen Bauteilen bestückt und deshalb auf eine Stromversorgungseinrichtung, beispielsweise auf eine Batterie angewiesen.It is known to use hand-movable trolleys, e.g. Shopping trolleys to be equipped with deposit locks so that the transport trolleys, for example in self-service shops, are available to customers when they first put a deposit in the deposit lock so that the transport trolley can be released from a queue of transport trolleys coupled together. Transport trolleys designed in this way are described in more detail, for example, in EP 0 199 274B1 and can be equipped with an information device such as this, e.g. is proposed in EP 0 254 170. The information device is equipped with electronic components and therefore relies on a power supply device, for example a battery.
Die PCT/GB 95/02380 beschreibt eine Griffeinheit, die zum Anbau an einen von Hand bewegbaren Transportwagen bestimmt ist. Die Griffeinheit beinhaltet wenigstens eine auf elektrische Energie angewiesene Einrichtung, beispielsweise einen Bildschirm sowie ein an der Griffeinheit ange- ordnetes Pfandschloss, dessen Funktion so gewählt ist, wie vorab beschrieben. Eine Energiequelle, die Bestandteil des Transportwagens ist, sorgt für die Bereitstellung der erforderlichen elektrischen Energie, die für die Einrichtung bestimmt ist.PCT / GB 95/02380 describes a handle unit that is intended for attachment to a hand-movable trolley. The handle unit contains at least one device that depends on electrical energy, for example a screen and a deposit lock arranged on the handle unit, the function of which is selected as described above. An energy source, which is part of the trolley, provides the necessary electrical energy that is intended for the facility.
In der DE 196 06 660 AI wird ein Pfandschloss für Einkaufswagen oder Gepäckwagen beschrieben, in welches ein Pfand einsteckbar ist, wobei das Pfand oder das Pfandschloss ein „sprechendes" Pfand oder Pfandschloss ist. Die erforderliche elektrische Energie für dieses Pfandschloss wird durch Akkus bereitgestellt, die sich im Pfandschloss befinden. Das Pfand ist als Karte ausgebildet, die einen -Minischalter, insbesondere eine Folienschalter aufweist, der betätigt wird, sobald die Karte in das Pfandschloss geschoben wird. Das Einschieben des Pfandes löst im Pfandschloss eine Verstärkerelektronik aus, welche das Ertönen eines Textes bewirkt. Das technische Mittel, das den Stromkreis innerhalb des Pfandschlosses schließt oder unterbricht, befindet sich auf dem als Karte gestalteten Pfand, das dem Kunden gehört. Wird mit dem Pfand sorglos umgegangen, besteht die Gefahr einer Beschädigung des Pfandes, so dass der auf dem Pfand befindliche Minischalter sehr rasch seine Funktion verlieren kann. Auch häufiges Be- nutzen des Pfandes lässt eine schnelle Abnützung des Pfandes und damit den Verlust der Funktion befürchten.DE 196 06 660 AI describes a deposit lock for shopping carts or luggage trolleys, into which a deposit can be inserted, the deposit or the deposit lock being a "talking" deposit or deposit lock. The required electrical energy for this deposit lock is provided by batteries, which are in the deposit lock. The deposit is as Card formed, which has a mini switch, in particular a membrane switch, which is actuated as soon as the card is pushed into the deposit lock. Inserting the deposit triggers an amplifier electronics in the deposit lock, which causes a text to sound. The technical means that closes or breaks the circuit inside the deposit lock is on the card-shaped deposit that belongs to the customer. If the deposit is handled carelessly, there is a risk of damage to the deposit, so that the mini-switch on the deposit can very quickly lose its function. Frequent use of the deposit also leads to fear that the deposit will wear out quickly and that the function will be lost.
Um allgemein die für die Funktion der Einrichtung erforderliche Energiequelle nicht zu überfordern und darüber hinaus einen Missbrauch der Ein- richtung zu vermeiden, wenn die Transportwagen nicht benützt werden, ist es ratsam, die elektrische Energie nur dann zur Verfügung zu stellen, wenn diese bei der Benutzung der Transportwagen benötigt wird.In order not to overwhelm the energy source required for the function of the device in general and also to avoid misuse of the device when the transport trolleys are not in use, it is advisable to make the electrical energy available only when it is used by the Use of the trolley is required.
Es ist Aufgabe der Erfindung, einen Transportwagen der hier vorliegenden Art so weiterzuentwickeln, dass ein sparsamer Umgang der zur Verfügung stehenden elektrischen Energie erzielbar ist, dass ein Missbrauch der Einrichtung in der vorab beschriebenen Art auf einfache Weise vermieden werden kann und dass der erforderliche Stromkreis auf zuverlässige Weise geschlossen und auch wieder unterbrochen werden kann.It is an object of the invention to further develop a transport trolley of the type present here in such a way that the available electrical energy can be used economically, that misuse of the device in the manner described above can be avoided in a simple manner and that the required circuit is available can be reliably closed and interrupted again.
Die Lösung der Aufgabe besteht darin, dass das Pfandschloss in den Stromkreis eingebunden ist und dass der Stromkreis durch Mitwirken eines im Pfandschloss befindlichen Schaltelementes nach Einführen eines Pfandes in das Pfandschloss geschlossen und nach Herausgabe des Pfandes unterbro- chen ist.The solution to the problem is that the deposit lock is integrated in the circuit and that the circuit is closed by the cooperation of a switching element located in the deposit lock after inserting a deposit into the deposit lock and interrupted after the deposit has been released.
Die Erfindung nutzt in vorteilhafter Weise das Vorhandensein und die Funktion des Pfandschlosses. Nur dann, wenn ein Pfand im Pfandschloss eingeführt ist, kann der Transportwagen benützt werden und nur dann kann sich der Benutzer des Transportwagens der Einrichtung bedienen. Das Pfand wiederum kann nur dann zurückerhalten werden, wenn der Transportwagen nach seiner Benutzung wieder an eine Reihe gleicher Trans- portwagen angekoppelt wird. In dieser Lage ist der Transportwagen nicht benutzbar und in diesem Zustand ist, bedingt durch den unterbrochenen Stromkreis, eine Benutzung der Einrichtung ausgeschlossen. Dadurch lässt sich sowohl elektrische Energie einsparen als auch der zu befürchtende Missbrauch vermeiden. Ein weiterer, entscheidender Vorteil besteht darin, dass das technische Mittel, welches zum Schließen und zum Unterbrechen des Stromkreises erforderlich ist, im Inneren des Pfandschlosses untergebracht und deshalb von Benutzern des Transportwagens nicht erreichbar ist. Eine Beeinträchtigung der elektrischen Funktionen des Pfandschlosses ist somit nicht zu befürchten.The invention advantageously uses the presence and the function of the deposit lock. Only when a deposit is inserted in the deposit lock can the trolley be used and only then the user of the trolley uses the facility. The deposit can only be returned if the trolley is coupled to a row of the same trolley after it has been used. The transport trolley cannot be used in this position and, in this state, use of the device is ruled out due to the broken circuit. This can both save electrical energy and avoid the misuse to be feared. Another decisive advantage is that the technical means required to close and interrupt the circuit are housed inside the deposit lock and are therefore not accessible to users of the trolley. There is therefore no fear of impairing the electrical functions of the deposit lock.
Die Erfindung wird anhand von Ausführungsbeispielen näher erläutert. Es zeigtThe invention is explained in more detail using exemplary embodiments. It shows
Fig. 1 einen Transportwagen in Form eines Einkaufswagens sowie Fig. 2 und 3 je einen Übersichtsschaltplan.Fig. 1 is a trolley in the form of a shopping cart and Fig. 2 and 3 each have an overview circuit diagram.
Fig. 1 zeigt einen als Einkaufswagen gestalteten, von Hand bewegbaren Transportwagen 1. Der Transportwagen 1 ist bevorzugt so gestaltet, dass dieser in bekannter Weise mit gleichen Transportwagen 1 in einer Reihe platzsparend gestapelt werden kann. Neben einem Fahrgestell 2 weist der Transportwagen 1 in üblicher Weise wenigstens eine Absteileinrichtung 3 für zur transportierende Ware oder Güter auf. Im Beispiel ist die Absteileinrichtung 3 in ebenfalls bekannter Weise durch einen Korb gebildet. Der Transportwagen 1 ist mit einer Schiebeeinrichtung 4 ausgestattet, die beispielsweise so gestaltet sein kann, wie in der PCT/GB 95/02380 vorgeschlagen. Neben zwei Schiebegriffabschnitten 5 weist die Schiebeeinrich- tung 4 eine Einrichtung 7 in Form eines beispielsweise kleinen Bildschirmes auf. Der Bildschirm vermittelt dem Benutzer des Transportwagens 1 Informationen, z.B. während des Einkaufens. Zum Transportwagen 1 gehört auch eine Energiequelle 6, welche die Einrichtung 7 mit elektrischem Strom versorgt. Die Energiequelle 6 ist am Transportwagen 1 an geeigneter Stelle, z.B. an der Schiebeeinrichtung 4 so angeordnet, daß der Stapelvorgang des Transportwagens 1 nicht behindert wird. Bevorzugt an der Schiebeeinrichtung 4 angeordnet trägt der Transportwagen 1 ein bekanntes Pfandschloss 8, mit dessen Hilfe der Transportwagen 1 an das Pfandschloss 8 eines weiteren Transportwagens 1 angekoppelt werden kann. Das Bereitstellen von in Reihen gestapelten Transportwagen 1 , die mit Pfandschlössern 8 ausgestattet sind, ist mittlerweile üblich. Will man einen Transportwagen 1 einer Reihe gestapelter Wagen 1 entnehmen, muss ein Pfand, etwa eine Münze, oder ein Münzersatz oder auch ein scheckkartenähnlicher Auslöser in das Pfandschloss 8 des zu entnehmenden Transportwagens 1 eingeführt werden. Dieser Vorgang bewirkt ein Lösen des zu entnehmenden Transportwagens 1 von einer Reihe. Der Transportwagen 1 kann nun benutzt werden. Wird der Transportwagen 1 erneut an die Reihe gestapelter Transportwagen 1 angekoppelt, gibt das Pfandschloss 8 das zuvor entrich- tete Pfand wieder zurück. Das Pfandschloss 8 ist nun in den bereits zwischen der Einrichtung 7 und der Energiequelle 6 bestehenden Stromkreis 14 eingebunden. Diese Einbindung ist so gewählt, daß der Stromkreis 14 nach Einführung des Pfandes in das Pfandschloss 8 des Transportwagens 1 geschlossen und nach Herausgabe des Pfandes unterbrochen ist. Im Beispiel weist das Pfandschloss 8, so wie auch in der PCT/EP 90/00593 beschrieben, ein Schiebeteil 10 auf, das in das Gehäuse 9 des Pfandschlosses 8 einschiebbar ist. Zum Abkoppeln eines Transportwagens 1 muß ein Pfand in Form einer Münze in das aus dem Gehäuse 8 herausstehende Schiebeteil 10 gelegt und dieses in das Pfandschloss 8 eingeschoben werden. Diese Kon- struktion und Verfahrensweise nützt die Erfindung dadurch, vgl. auch Fig. 2 und 3, dass an dem Schiebeteil 10 an geeigneter Stelle ein kleiner Magnet 11 vorgesehen ist, der zum Einwirken auf ein Schaltelement 12 bestimmt ist, das sich im Inneren des Pfandschlosses 8 befindet und in den Stromkreis 14 eingebunden ist. In nicht eingeschobenem Zustand des Schiebeteiles 10 ist der Stromkreis 14 durch das Schaltelement 12 unterbrochen. Wird das Schiebeteil 10 in das Pfandschloss 8 eingeschoben, wirkt der Magnet 11 auf einen eisenmetallischen Kontaktarm 13 des Schaltelementes 12 und bewirkt eine Auslenkung des federnd befestigten Kontaktarmes 13 derart, dass der Kontaktarm 13 den Stromkreis 14 schließt und die Einrichtung 7 mit Strom versorgt wird und diese somit benutzbar ist. Die Einwirkung des Magnetes1 shows a transport trolley 1 designed as a shopping trolley and movable by hand. The transport trolley 1 is preferably designed in such a way that it can be stacked in a row to save space in a known manner with the same transport trolleys 1. In addition to a chassis 2, the trolley 1 has in the usual way at least one parting device 3 for goods or goods to be transported. In the example, the dividing device 3 is also formed in a known manner by a basket. The transport carriage 1 is equipped with a sliding device 4, which can be designed, for example, as proposed in PCT / GB 95/02380. In addition to two push handle sections 5, the pushing device 4 has a device 7 in the form of, for example, a small screen. The screen conveys information to the user of the trolley 1, for example while shopping. The trolley 1 also includes an energy source 6, which supplies the device 7 with electrical current. The energy source 6 is more suitable on the trolley 1 Place, for example on the sliding device 4 so that the stacking process of the trolley 1 is not hindered. Arranged preferably on the sliding device 4, the transport carriage 1 carries a known deposit lock 8, with the aid of which the transport carriage 1 can be coupled to the deposit lock 8 of a further transport carriage 1. The provision of transport wagons 1 stacked in rows, which are equipped with deposit locks 8, is now common. If you want to remove a transport carriage 1 from a row of stacked carriages 1, a deposit, for example a coin, or a coin substitute or a trigger similar to a credit card, must be inserted into the deposit lock 8 of the transport carriage 1 to be removed. This process causes the transport carriage 1 to be removed to be released from a row. The trolley 1 can now be used. If the transport carriage 1 is coupled again to the row of stacked transport carriages 1, the deposit lock 8 returns the previously paid deposit. The deposit lock 8 is now integrated into the circuit 14 already existing between the device 7 and the energy source 6. This integration is chosen so that the circuit 14 is closed after the deposit into the deposit lock 8 of the trolley 1 and is interrupted after the deposit has been released. In the example, the deposit lock 8, as also described in PCT / EP 90/00593, has a sliding part 10 which can be inserted into the housing 9 of the deposit lock 8. To uncouple a transport carriage 1, a deposit in the form of a coin must be placed in the sliding part 10 protruding from the housing 8 and this must be inserted into the deposit lock 8. The invention makes use of this construction and procedure, cf. 2 and 3 that a small magnet 11 is provided on the sliding part 10 at a suitable point, which is intended to act on a switching element 12 which is located in the interior of the deposit lock 8 and is integrated into the circuit 14. When the sliding part 10 is not inserted, the circuit 14 is interrupted by the switching element 12. If the sliding part 10 is inserted into the deposit lock 8, the magnet 11 acts on an iron-metal contact arm 13 of the switching element 12 and causes a deflection of the spring-mounted contact arm 13 in such a way that the contact arm 13 closes the circuit 14 and the device 7 with current is supplied and it is therefore usable. The action of the magnet
11 auf den Kontaktarm 13 dauert so lange an, so lange das Schiebeteil 10 eingeschoben ist. Wird der Transportwagen 1 wieder an einen weiteren Transportwagen 1 angekoppelt, indem das Kopplungsteil dieses Transport- wagens 1 in das Pfandschloss 8 des anzukoppelnden Transportwagens 1 eingeführt wird, so löst sich das Schiebeteil 10 und bewegt sich soweit aus dem Pfandschloss 8 heraus, dass das Pfand oder die Münze wieder entnommen werden kann. Der Bewegungsvorgang des Schiebeteiles 10 bewirkt eine Lageveränderung des Magneten 11 derart, dass dieser nicht mehr auf den Kontaktarm 13 des Schaltelementes 12 einwirken kann. Der federnd gelagerte Kontaktarm 13 federt deshalb wieder zurück in seine vorbestimmte Ausgangslage, in welcher der Stromkreis 14 unterbrochen ist.11 on the contact arm 13 lasts as long as the sliding part 10 is inserted. If the transport carriage 1 is coupled again to a further transport carriage 1 by inserting the coupling part of this transport carriage 1 into the deposit lock 8 of the transport carriage 1 to be coupled, the sliding part 10 is released and moves out of the deposit lock 8 to such an extent that the deposit or the coin can be removed again. The movement of the sliding part 10 causes a change in the position of the magnet 11 such that it can no longer act on the contact arm 13 of the switching element 12. The spring-mounted contact arm 13 therefore springs back into its predetermined starting position, in which the circuit 14 is interrupted.
Fig. 2 zeigt einen Übersichtsschaltplan, der auf die in Fig. 1 beschriebene Anordnung bezogen ist. Am Stromkreis 14 ist die Energiequelle 6, ferner die Einrichtung 7 sowie das Pfandschloss 8 angeschlossen. Im Inneren desFIG. 2 shows an overview circuit diagram which relates to the arrangement described in FIG. 1. The energy source 6, the device 7 and the deposit lock 8 are connected to the circuit 14. Inside the
Pfandschlosses 8 ist das in den Stromkreis 14 eingebundene SchaltelementDeposit lock 8 is the switching element integrated in the circuit 14
12 angeordnet. Am Schaltelement 12, das sinnbildlich dargestellt ist, befindet sich der federnd befestigte Kontaktarm 13. Das Schiebeteil 10 mit dem Pfand ist in das Pfandschloss 8 eingeschoben. Der im Schiebeteil 10 untergebrachte Magnet 11 wirkt auf den Kontaktarm 13 und zieht diesen an sich heran. Der Stromkreis 14 ist geschlossen.12 arranged. The spring-mounted contact arm 13 is located on the switching element 12, which is shown symbolically. The sliding part 10 with the deposit is inserted into the deposit lock 8. The magnet 11 accommodated in the sliding part 10 acts on the contact arm 13 and pulls it towards itself. The circuit 14 is closed.
Fig. 3 zeigt den gleichen Schaltplan, jedoch mit nunmehr unterbrochenem Stromkreis 14. Die Unterbrechung wird dann erzielt, wenn das Schiebeteil 10 ein Stück weit aus dem Pfandschloss 8 herausgeschoben ist. In dieser Lage kann der Magnet 11 nicht mehr auf den Kontaktarm 13 des ebenfalls sinnbildlich dargestellten Schaltelementes 12 wirken. Deshalb wird der Kontaktarm 13, da er entsprechend federnd befestigt ist, durch die auf ihn einwirkende Federkraft aus seiner den Stromkreis 14 schließenden Lage in eine den Stromkreis 14 unterbrechende Position bewegt, in welcher er verharrt, bis er durch das eingeschobene Schiebeteil 10, dessen Magnet 11 nunmehr wieder auf den Kontaktarm 13 einwirkt, aus seiner Lage bewegt wird, um den Stromkreis 14 zu schließen. Die Erfindung lässt verschiedene Ausführungen und Modifikationen zu. So kann das Schaltelement 12 z.B. rein mechanisch wirken. Es kann als Näherungsschalter oder als sog. „Reedkontakt" ausgebildet sein. Ebenso lässt sich die Erfindung mit Pfandschlössern 8 verwirklichen, die kein Schiebeteil 10 aufweisen. In diesem Falle wirkt das in das Pfandschloss 8 eingebrachte Pfand direkt auf den Kontaktarm 13 des Schaltelementes 12, um diesen durch Druck in die gewünschte Lage zu bringen und/oder in dieser Lage zu halten. Als Energiequelle 6 bieten sich Batterien oder Solarzellen an.3 shows the same circuit diagram, but with the circuit 14 now interrupted. The interruption is achieved when the sliding part 10 is pushed out of the deposit lock 8 to a certain extent. In this position, the magnet 11 can no longer act on the contact arm 13 of the switching element 12, also shown symbolically. Therefore, the contact arm 13, since it is resiliently attached, is moved by the spring force acting on it from its position closing the circuit 14 into a position interrupting the circuit 14, in which it remains until it is inserted by the inserted sliding part 10, the magnet 11 now acts again on the contact arm 13, is moved out of its position to close the circuit 14. The invention permits various designs and modifications. For example, the switching element 12 can act purely mechanically. It can be designed as a proximity switch or as a so-called “reed contact”. Likewise, the invention can be implemented with deposit locks 8 which have no sliding part 10. In this case, the deposit introduced into the deposit lock 8 acts directly on the contact arm 13 of the switching element 12, in order to bring it into the desired position by pressure and / or to keep it in this position. Batteries or solar cells are suitable as energy sources 6.
Schließlich kann als Einrichtung 7 jedes weitere mit Strom zu versorgende Bauteil, Gerät oder dergleichen, betrachtet werden, das bei der Benutzung des Transportwagens 1 für den Benutzer dienlich ist. Als Einrichtung 7 können beispielsweise ein Lautsprecher oder eine Beleuchtung, ein elektronischer Rechner oder auch ein elektromotorischer Antrieb Verwendung finden, der zum Antreiben von wenigstens einem der Räder des Transportwagens 1 bestimmt ist. In diesem zuletzt genannten Falle wirkt das Unterbrechen oder das Schließen des Stromkreises 14 beispielsweise auf eine elektronische Baueinheit, die zum Ansteuern des elektromotorischen Antriebes des Transportwagens 1 bestimmt ist. Wird durch entsprechendes Betätigen des Pfandschlosses 8 der Stromkreis 14 unterbrochen, erhält die elektronische Baueinheit keinen Strom. Dadurch ist ein Ansteuern des elektromotorischen Antriebs nicht möglich, so dass dieser auch nicht we- nigstens eines der Räder des Transportwagens 1 antreiben kann. Dieser Zustand wird gewünscht oder ist sogar erforderlich, wenn der Transportwagen 1 bei Nichtbenutzung an eine Reihe weiterer gestapelter Transportwagen 1 angekoppelt ist. Der Stromkreis 14 wird erst geschlossen, wenn ein Pfand in das Pfandschloss 8 dieses Wagens eingeführt wird. Erst dann kann der elektromotorische Antrieb aktiviert und der Transportwagen 1 bewegt werden. Finally, any other component, device or the like which is to be supplied with power and which is useful for the user when using the transport carriage 1 can be regarded as the device 7. A loudspeaker or lighting, an electronic computer or even an electric motor drive can be used as the device 7, which is intended for driving at least one of the wheels of the transport vehicle 1. In this latter case, the interruption or closing of the circuit 14 acts, for example, on an electronic unit which is intended to control the electromotive drive of the transport vehicle 1. If the circuit 14 is interrupted by corresponding actuation of the deposit lock 8, the electronic unit receives no current. As a result, it is not possible to control the electromotive drive, so that it cannot drive at least one of the wheels of the transport vehicle 1. This state is desired or even necessary if the transport carriage 1 is coupled to a number of further stacked transport carriages 1 when not in use. The circuit 14 is only closed when a deposit is inserted into the deposit lock 8 of this car. Only then can the electric motor drive be activated and the trolley 1 moved.
