Abstract

In a transport trolley, which can be pushed into an identically designed transport trolley and which is equipped with an appropriate device in the form of a supporting surface or a basket for receiving products or transport material, depending on the particular embodiment handle-supporting arms made approximately U-shaped at the free end or handle-supporting tubes of oval or circular cross-section are firmly attached to the rear end of this device; between the handle-supporting arms or tubes is mounted a generally tubular handle, in the region of which is arranged a coin-deposit lock which is equipped with a corresponding coupling device, so that a mutual coupling and uncoupling of transport trolleys relative to one another or to or from a collecting point becomes possible. In the design according to the invention of such a transport trolley, one of its handle-supporting arms or one of the handle-supporting tubes is made shorter, and the coin-deposit lock is fastened to the shorter handle-supporting arm or tube in such a way that it is so integrated in the transport trolley in a space-saving way that the outer dimensions of the latter correspond virtually to those of hitherto conventional transport trolleys precisely in the region of one of the two handle-supporting arms or tubes. Consequently, as a result of the design and arrangement of the coin-deposit lock, the handle provided between the two handle-supporting arms or tubes is available to the same extent as on the transport trolleys used hitherto.

Description

Die Erfindung betrifft einen Transportwagen, der in einen gleichartig ausgeführten Transportwagen einschiebbar ist und mit einer zur Aufnahme von Waren oder Transportgut versehenen Einrichtung ausgestattet ist, an deren rückwärtigen Ende auf beiden Seiten durch einen im allgemeinen rohrförmigen Griff verbundene, am freien Ende etwa U-förmig ausgeführte Grifftragarme oder Grifftragrohre fest angebracht sind, in deren Bereich ein Münzpfandschloß angeordnet ist, das ein gegenseitiges An- und Abkoppeln von Transportwagen mit und ohne Inanspruchnahme einer Sammelstelle ermöglicht.The invention relates to a transport trolley which can be inserted into a transport trolley of the same type and is equipped with a device provided for receiving goods or transport goods, at the rear end of which is connected on both sides by a generally tubular handle and is approximately U-shaped at the free end Executed handle support arms or handle support tubes are firmly attached, in the area of which a coin deposit lock is arranged, which enables a mutual coupling and uncoupling of trolleys with and without using a collection point.

Solche Transport- oder Einkaufswagen mit Münzpfandschlössern sind beispielsweise aus den deutschen Patenten 2 554 916 und 2 900 367 sowie aus den europäischen Patenten 70 997 und 199 274 bekannt. Solche Transport- oder Einkaufswagen werden auf Pfandbasis ausgeliehen und lassen sich entweder untereinander an- und abkoppeln und/oder an fest installierten Sammelstellen gezielt ankoppeln und damit einsammeln, um zu jeder Zeit wieder ausgeliehen werden zu können.Such transport or shopping trolleys with coin-operated locks are known, for example, from German patents 2 554 916 and 2 900 367 and from European patents 70 997 and 199 274. Such transport or shopping trolleys are borrowed on a deposit basis and can either be coupled and uncoupled and / or specifically coupled to fixed collection points and thus collected so that they can be borrowed again at any time.

Durch derartige Einkaufswagen-Sammel- und -Ausleihsysteme kann insbesondere in Supermärkten vermieden werden, daß beispielsweise leere Einkaufswagen wahllos und ungenutzt auf Parkplätzen, auf den Zufahrtsstraßen u.ä. herumstehen. An diesen Einkaufswagen müssen jedoch die Münzpfandschlösser an geeigneten Stellen so angebracht sein, daß sowohl ein Ineinanderschieben als auch eine bequeme Handhabung der Einkaufswagen wagen erhalten bleiben.Such shopping cart collection and loan systems can be used to prevent, in particular in supermarkets, that, for example, empty shopping carts can be used indiscriminately and unused in parking lots, on the access roads and the like. stand around. However, the coin deposit locks must be attached to these shopping trolleys at suitable points in such a way that both pushing one into the other and convenient handling of the shopping trolleys dare to remain.

Bei einem Anbringen eines beispielsweise aus dem DE-PS 2 554 916 bekannten Münzpfandschlosses an Einkaufswagen ergeben sich vor allem dadurch Schwierigkeiten, daß dieses Münzpfandschloß aufgrund seiner Größe teilweise in den Ladebereich des Korbes eines Einkaufswagens hineinragt, und dadurch ein Beladen des Korbes von der Griffseite des Einkaufswagens her zumindest beeinträchtigt, wenn nicht sogar behindert wird.When attaching a coin deposit lock, for example from DE-PS 2 554 916, to shopping trolleys, difficulties arise primarily because this coin deposit lock partially projects into the loading area of the basket of a shopping trolley due to its size, and thereby loading the basket from the handle side of the The cart is at least affected, if not obstructed.

Da die aus dem DE-PS 2 900 367 und dem europäischen Patent 70 997 bekannten Münzpfandschlösser erheblich kleiner ausgeführt sind als das vorstehend beschriebene Münzpfandschloß, lassen sich diese Münzpfandschlösser ohne Schwierigkeit im rückwärtigen Bereich des Einkaufswagens an dem dort vorgesehenen Griff befestigen. Bei diesen Münzpfandschlössern besteht jedoch die Gefahr, daß sie entweder absichtlich bezüglich der Griffachse verdreht werden, oder daß sie im Laufe der Zeit beispielsweise durch Lockerwerden ihre Befestigungselemente ihre Lage etwas verändern.Since the coin deposit locks known from DE-PS 2 900 367 and the European patent 70 997 are made considerably smaller than the coin deposit lock described above, these coin deposit locks can be attached to the handle provided there without difficulty in the rear area of the shopping cart. With these coin-operated locks, however, there is a risk that they will either be intentionally rotated with respect to the handle axis, or that they will change their position somewhat over time, for example by loosening their fastening elements.

Der vorstehend angeführte Nachteil ist bei dem aus dem europäischen Patent 199 274 bekannten Münzpfandschloß im wesentlichen dadurch vermieden, daß ein allerdings verhältnismäßig großvolumiges Münzpfandschloß im Bereich eines der beiden Grifftragarme eines Einkaufswagens angeordnet ist und sich dabei einerseits am Grifftragarm und andererseits aber auch noch an dem zwischen den beiden Grifftragarmen vorgesehenen Griff abstützt. Nachteilig bei diesem aus dem EP 199 274 bekannten Münzpfandschloß ist jedoch, das es einerseits immer an dem freien Ende eines U-förmig ausgeführten Grifftragarms abgestützt sein muß und andererseits auch noch in beachtlichem Maße in den Griffbereich hinein vorsteht und dadurch den an dem Griff zur Verfügung stehenden Platz in nicht unerheblichem Maße einschränkt.The above-mentioned disadvantage is essentially avoided in the coin deposit lock known from European Patent 199 274 by the fact that a relatively large-volume coin deposit lock is arranged in the area of one of the two handle support arms of a shopping cart and is located on the one hand on the handle support arm and on the other hand also on the between supports the two handle support arms provided. A disadvantage of this coin deposit lock known from EP 199 274, however, is that on the one hand it always has to be supported on the free end of a U-shaped handle support arm and on the other hand it also protrudes to a considerable extent into the handle area and is therefore available on the handle standing space to a not inconsiderable degree.

Aus der DE-A-37 14 115 ist es bekannt, einen Teil des Volumens der Schiebegriffeinrichtung zur Gestaltung und Unterbringung des Münzpfandschlosses zu verwenden, dergestalt, daß das Münzpfandschloß zumindest mit einem Schiebegriffabschnitt auf einer Seite verbunden ist, und auf der anderen Seite an der Griffkappe befestigt ist, welche Grifftragarme bzw. Grifftragrohr mit dem Schiebegriff verbindet.From DE-A-37 14 115 it is known to use part of the volume of the push handle device for designing and accommodating the coin deposit lock in such a way that the coin deposit lock is connected to at least one push handle section on one side and on the other side on the Handle cap is attached, which connects handle support arms or handle support tube with the push handle.

Aufgabe der Erfindung ist es daher, einen Transportwagen der eingangs beschriebenen Art so auszubilden, daß unter Vermeidung der verschiedenen Nachteile der bekannten Transportwagen-Ausführungen ein Münzpfandschloß zumindest weitgehend allein im Bereich eines der Grifftragarme oder eines der Grifftragrohre integrierbar ist.The object of the invention is therefore to provide a trolley type described at the outset so that, while avoiding the various disadvantages of the known trolley designs, a coin deposit lock can be integrated at least largely solely in the area of one of the handle support arms or one of the handle support tubes.

Gemäß der Erfindung ist dies bei einem Transportwagen nach dem Oberbegriff des Anspruchs 1 dadurch erreicht, daß einer der Grifftragarme oder eines der Grifftragrohre kürzer ausgebildet ist, und daß an dem kürzeren Grifftragarm oder -rohr ein Münzpfandschloß so befestigt ist, daß das Gehäuse des Münzpfandschlosses mit der senkrecht verlaufenden Mittenebene der Grifftragarme oder -rohre zusammenfällt. Gemäß einer bevorzugten Ausführungsform der Erfindung ist ferner an einer Außenfläche des Gehäuses des Münzpfandschlosses eine Aufnahme zur Halterung und Sicherung des im allgemeinen rohrförmigen Griffs vorgesehen.According to the invention, this is achieved in a trolley according to the preamble of claim 1 in that one of the handle support arms or one of the handle support tubes is shorter, and that a coin deposit lock is attached to the shorter handle support arm or tube so that the housing of the coin deposit lock with the vertical center plane of the handle support arms or tubes coincides. According to a preferred embodiment of the invention, a receptacle for holding and securing the generally tubular handle is also provided on an outer surface of the housing of the coin deposit lock.

Der besondere Vorteil des erfindungsgemäßen Transportwagens ist somit darin zu sehen, daß der Raum, welcher bisher von dem im allgemeinen U-förmig ausgeführten Ende eines der Grifftragarme beansprucht worden ist, nunmehr in platzsparender Weise zur Unterbringung des Münzpfandschlosses ausgenutzt ist. Oder mit anderen Worten, bei dem erfindungsgemäßen Transportwagen ist das Münzpfandschloß so integriert, daß die Außenabmessungen des Transportwagens gerade im Bereich eines der beiden Grifftragarme oder -rohre praktisch denjenigen der bisher verwendeten Transportwagen entsprechen, und daß insbesondere der Platz an dem zwischen den beiden Grifftragarmen oder -rohren vorgesehene Griff praktisch in vollem Umfang zur Verfügung steht.The particular advantage of the trolley according to the invention can thus be seen in the fact that the space which has previously been claimed by the generally U-shaped end of one of the handle support arms is now used in a space-saving manner for accommodating the coin deposit lock. Or in other words, in the transport trolley according to the invention, the coin deposit lock is integrated in such a way that the outer dimensions of the transport trolley, in the area of one of the two handle support arms or tubes, practically correspond to those of the transport trolleys previously used, and in particular that the space between the two handle support arms or -Pipes provided handle is practically fully available.

Die Erfindung schließt alle gängigen Ausführungsformen von Transportwagen sowie von Einkaufswagen ein, die zur Zeit angeboten und benutzt werden. Dazu zählen beispielsweise alle Einkaufswagen, welche aufgrund ihrer in Fahrtrichtung sich verjüngenden Gestalt zum Zwecke des platzsparenden Stapelns ineinanderschiebbar ausgebildet sind. Üblicherweise haben solche Einkaufswagen ein mit vier Fahrrollen versehenes Fahrgestell, welches einen Korb trägt, der rückseitig durch eine um eine im oberen Bereich befindliche, waagrechte Achse drehbare, in das Korbinnere schwenkbare Klappe begrenzt ist.The invention includes all current embodiments of trolleys and shopping carts that are currently offered and used. These include, for example, all shopping carts which, owing to their shape tapering in the direction of travel, are designed to be able to be pushed into one another for the purpose of space-saving stacking. Such shopping carts usually have a chassis provided with four castors, which carries a basket which is bounded on the rear by a flap which can be rotated about a horizontal axis located in the upper region and can be pivoted into the basket interior.

Am oberen rückwärtigen Ende des Korbes befinden sich bei den bisher üblichen Einkaufswagen auf beiden Seiten jeweils Grifftragarme, die durch einen Griff verbunden sind, der vorzugsweise einen rohrförmigen Querschnitt aufweist und bei den bekannten Einkaufswagen-Ausführungen mit den Grifftragarmen durch Verschrauben fest verbunden ist.At the upper rear end of the basket there are handle support arms on both sides in the previously usual shopping carts, which are connected by a handle, which preferably has a tubular cross section and is firmly connected to the handle support arms by screwing in the known shopping cart designs.

Vorzugsweise auf der in der üblichen Fahrt- bzw. Schieberichtung gesehen rechten Seite eines Einkaufswagens ist, wie in Fig.1 schematisch dargestellt ist, ein kürzerer, im allgemeinen aus zwei schräg nach oben verlaufenden Stäben gebildeter Grifftragarm 1 vorgesehen. An diesem kürzeren Grifftragarm 1 ist ein in Fig.1 schematisch wiedergegebenes Münzpfandschloß 2 in einer nachstehend im einzelnen beschriebenen Weise gehaltert.Preferably, on the right-hand side of a shopping trolley, as seen in the usual direction of travel or sliding, as shown schematically in FIG. 1, a shorter handle support arm 1 is provided, which is generally formed from two sloping bars. A coin deposit lock 2, shown schematically in FIG. 1, is held on this shorter handle support arm 1 in a manner described in detail below.

Wie aus der Draufsicht in Fig.2 zu ersehen ist, ist an einer dem Griff 5 zugewandten Außenfläche 21a eines Gehäuses 21 des Münzpfandschlosses 2 eine Aufnahme 22 vorgesehen, welche ebenso wie das Gehäuse 21 vorzugsweise aus einem elastischen, jedoch widerstandsfähigen Kunststoff hergestellt ist und mit dem Gehäuse 21 eine Einheit bildet. Wie aus Fig.2 zu ersehen sehen ist, ist der Griff 5 durch Hineinschieben in der Aufnahme 22 untergebracht und kann erforderlichenfalls durch eine von der Griffunterseite eingebrachte Schraube an der Aufnahme 22 gesichert sein. In üblicher Weise ist der Griff 5 mit dem anderen, auf der linken Seite vorgesehenen, unverkürzten Grifftragarm durch Verschrauben fest verbunden.As can be seen from the top view in FIG. 2, a receptacle 22 is provided on an outer surface 21a of a housing 21 of the coin deposit lock 2 facing the handle 5, which, like the housing 21, is preferably made of an elastic but resistant plastic and with the housing 21 forms a unit. As can be seen from Fig.2 can be seen, the handle 5 is accommodated in the receptacle 22 by pushing it in and, if necessary, can be secured to the receptacle 22 by a screw inserted from the underside of the handle. In the usual way, the handle 5 is firmly connected to the other, unshortened handle support arm provided on the left side by screwing.

In Fig.1 und 2 ist über dem kürzeren Grifftragarm 1 gestrichelt eine Aufnahmeöffnung 23 angedeutet, in welche ein Schlüssel einführbar ist, welcher mittels einer Kette mit einem ordnungsgemäß abgestellten und an einem anderen Transportwagen bzw. einer Sammelstelle angekoppelten Transportwagen verbunden ist. Eine entsprechende Kette 3 ist an dem der Schlüsselaufnahme 23 diametral gegenüberliegenden Seite des Gehäuses 21 des Münzofandschlosses 2 angebracht und in Fig.2 lediglich durch einige Kettenglieder angedeutet. Ferner ist in dem Gehäuse 21 des Münzpfandschlosses 2 strichliert ein Münzeeinwurf- und -ausgabeschlitz 24 angedeutet. Ferner ist in Fig.1 durch zwei dünne Kreise das in der Aufnahme 22 untergebrachte Ende 5a des Griffes 5 angedeutet.In FIGS. 1 and 2, a reception opening 23 is indicated by dashed lines above the shorter handle support arm 1, into which a key can be inserted, which key is connected by a chain to a transport trolley which has been properly parked and coupled to another transport trolley or a collection point. A corresponding chain 3 is attached to the diametrically opposite side of the housing 21 of the coin-operated lock 2 and is indicated in FIG. 2 only by a few chain links. Furthermore, a coin inserting and dispensing slot 24 is indicated by dashed lines in the housing 21 of the coin deposit lock 2. Furthermore, the end 5a of the handle 5 accommodated in the receptacle 22 is indicated in FIG. 1 by two thin circles.

Wie aus den Fig.1 und 2 zu ersehen ist, ist die Abmessung zwischen der strichpunktiert angedeuteten Mittenachse des Griffes 5 und dem kürzeren Grifftragarm 1 so bemessen, daß der Griff 5 in seiner bisherigen Position angeordnet bleibt und sicher gehaltert ist. Dies bedeutet jedoch, daß das Münzpfandschloß 2 im wesentlichen in dem Bereich oder Raum untergebracht ist, welcher bisher von dem U-förmig ausgeführten Ende eines bei den bekannten Einkaufswagen-Ausführungsformen vorgesehenen Grifftragarms sowie einer an dem freien Ende eines solchen Grifftragarms vorgesehenen Grifftasche ausgefüllt worden ist, an welcher ein dem Ansatz 22 entsprechender Ansatz zur Aufnahme des Griffes 5 ausgebildet ist. Mit anderen Worten, das an dem kürzeren Grifftragarm 1 angebrachte Münzpfandschloß 2 ist in Verlängerung des kürzeren Grifftragarms 1 angebracht und somit nach seiner Montage an bzw. in dem erfindungsgemäßen Transportwagen integriert. Hierbei ist der von dem integrierten Münzpfandschloß 2 benötigte Raum praktisch kaum oder allenfalls nur unwesentlich größer als der Raum, welcher bisher von der zur Verschraubung des Griffs 5 dort vorgesehenen Grifftasche eingenommen wurde.As can be seen from FIGS. 1 and 2, the dimension between the center axis of the handle 5 indicated by dash-dotted lines and the shorter handle support arm 1 is such that the handle 5 remains in its previous position and is securely held. However, this means that the coin deposit lock 2 is essentially accommodated in the area or space which has previously been filled by the U-shaped end of a handle support arm provided in the known shopping trolley embodiments and a handle pocket provided on the free end of such a handle support arm , on which an approach corresponding to the approach 22 for receiving the handle 5 is formed. In other words, the coin deposit lock 2 attached to the shorter handle support arm 1 is attached as an extension of the shorter handle support arm 1 and is thus integrated after or on the transport trolley according to the invention. Here, the space required by the integrated coin deposit lock 2 is practically hardly or at most only insignificantly larger than the space previously occupied by the handle pocket provided for screwing the handle 5 there.

In den Fig.3 bis 7 sind verschiedene vorteilhafte Ausgestaltungen eines kürzeren Grifftragarms 1 sowie entsprechend angepaßte Ausführungen des Gehäuses 21 des Münzpfandschlosses 2 dargestellt. So sind in der in Fig.3 wiedergegebenen, vorteilhaften Ausgestaltung des kürzeren Grifftragarms 1 dessen beide schräg nach unten verlaufenden Schenkel 1a durch ein Verbindungsteil 1b starr miteinander verbunden, so daß dadurch die fest vorgegebene Lagebeziehung der beiden Schenkel 1a des Grifftragarms 1 gesichert ist. Im Inneren des Gehäuses 21 des Münzpfandschlosses 2 ist beispielsweise ein in Fig.3 gestrichelt wiedergegebenes, L-förmiges Halteteil fest integriert, so daß das Münzpfandschloß 2 beispielsweise mittels Schrauben fest und sicher an dem Verbindungsteil 1b des Grifftragarms 1 anbringbar ist.3 to 7 show various advantageous configurations of a shorter handle support arm 1 and correspondingly adapted designs of the housing 21 of the coin deposit lock 2. Thus, in the advantageous embodiment of the shorter handle support arm 1 shown in FIG. 3, its two legs 1a, which run obliquely downwards, are rigidly connected to one another by a connecting part 1b, so that the fixed predetermined positional relationship of the two legs 1a of the handle support arm 1 is secured. In the interior of the housing 21 of the coin deposit lock 2, for example, an L-shaped holding part shown in dashed lines in FIG.

In Fig.4 ist eine weitere vorteilhafte Ausgestaltung des vorderen Endes des kürzeren Grifftragarms 1 schematisch wiedergegeben. Bei dieser vorteilhaften Ausgestaltung des freien Endes des kürzeren Grifftragarms 1 sind dessen beiden Schenkel 1a unterschiedlich lang ausgebildet, und zwar ist in Fig.4 der untere Schenkel länger als der obere Schenkel. Zur Aufnahme dieser beiden unterschiedlich langen Schenkel 1a sind in dem Gehäuse 21 entsprechend tief ausgebildete Vertiefungen 7 vorgesehen, in welche die entsprechenden Schenkel 1a des kürzeren Grifftragarms 1 einschiebbar sind und dann in dieser Lage mittels Schrauben gesichert sind, wofür in dem Gehäuse 21 entsprechende Aufnahmeöffnungen 27 vorgesehen sind.A further advantageous embodiment of the front end of the shorter handle support arm 1 is shown schematically in FIG. In this advantageous embodiment of the free end of the shorter handle support arm 1, its two legs 1a are of different lengths, namely in FIG. 4 the lower leg is longer than the upper leg. To accommodate these two legs 1a of different lengths, correspondingly deep recesses 7 are provided in the housing 21, into which the corresponding legs 1a of the shorter handle support arm 1 can be inserted and then secured in this position by means of screws, for which purpose corresponding opening openings 27 in the housing 21 are provided.

Bei der in Fig.5 dargestellten Ausgestaltung des kürzeren Grifftragarms 1 ist der in Fig.5 kürzere, obere Schenkel 1a' etwa rechtwinklig in Richtung zu dem längeren, in Fig.5 unteren Schenkel 1a umgebogen. Nach einem Einschieben des längeren Schenkels 1a in eine entsprechend bemessene Vertiefung 7' im Gehäuse 21 wird der umgebogene Teil des anderen Schenkels 1a' in einer entsprechenden Ausnehmung 8 im Gehäuse 21 untergebracht. Mittels mindestens einer Schraube wird dann das Gehäuse 21 an dem umgebogenen Teil des Schenkels 1a' des kürzeren Grifftragarms 1 gesichert.In the embodiment of the shorter handle support arm 1 shown in FIG. 5, the upper leg 1a ′ which is shorter in FIG. 5 is bent approximately at a right angle in the direction of the longer leg 1a in FIG. After the longer leg 1a has been inserted into a correspondingly dimensioned recess 7 'in the housing 21, the bent part of the other leg 1a' is accommodated in a corresponding recess 8 in the housing 21. The housing 21 is then secured to the bent part of the leg 1a 'of the shorter handle support arm 1 by means of at least one screw.

Bei einer weiteren vorteilhaften Ausgestaltung des kürzeren Grifftragarms 1 sind dessen beide Schenkel 1a etwa gleich lang. An den beiden etwa gleich langen Schenkeln 1a ist eine Tragplatte 9 befestigt, vorzugsweise angeschweißt. Wenn in dem Gehäuse 21 des Münzpfandschlosses 2 beispielsweise ein dem L-förmigen Halteteil 26 in Fig.3 entsprechendes Halteteil untergebracht und integriert ist, ist das Münzpfandschloß 2 vorzugsweise wiederum mittels Schrauben an der Trageplatte 9 des kürzeren Grifftragarms 1 befestigt.In a further advantageous embodiment of the shorter handle support arm 1, its two legs 1a are approximately of the same length. A support plate 9 is fastened, preferably welded, to the two legs 1a of approximately the same length. If, for example, a holding part corresponding to the L-shaped holding part 26 in FIG. 3 is accommodated and integrated in the housing 21 of the coin-operated lock 2, the coin-operated lock 2 is in turn preferably fastened to the support plate 9 of the shorter handle support arm 1 by means of screws.

In Fig.7 ist eine vorteilhafte Weiterbildung der Ausgestaltung nach Fig.6 dargestellt. Bei dieser Ausführungsform ist eine an den etwa gleich langen Schenkeln 1a des kürzeren Grifftragarms 1 befestigte Tragplatte 9' in einer Ausnehmung 29 des Gehäuses 2 untergebracht, wobei die Ausnehmung 29 so ausgebildet ist, daß sie die eingebrachte Tragplatte 9' sowie das vordere Ende der beiden Schenkel 1a formschlüssig umgreift. Erforderlichenfalls ist das Gehäuse 21 mittels Schrauben an der Tragplatte 9 gesichert.FIG. 7 shows an advantageous development of the configuration according to FIG. 6. In this embodiment, a support plate 9 'fastened to the legs 1a of approximately the same length of the shorter handle support arm 1 is accommodated in a recess 29 in the housing 2, the recess 29 being designed such that it supports the inserted support plate 9' and the front end of the two Legs 1a grips positively. If necessary, the housing 21 is secured to the support plate 9 by means of screws.

In Fig.8 ist in einer Draufsicht von oben eine modifizierte Ausgestaltung eines Gehäuses 21' des Münzpfandschlosses 2 wiedergegeben, an welchem eine der Aufnahme 22 in Fig.1 entsprechende Aufnahme 22' als ein integrierter Teil ausgebildet ist, an welchem der Griff 5 gehaltert und erforderlichenfalls entsprechend gesichert ist. An dem einem kürzeren Grifftragrohr 10 zugewandten Ende des Gehäuses 21' weist letzteres eine diesem Grifftragrohr 10 angepaßte Ausnehmung 8' auf. Das Gehäuse 21' des Münzpfandschlosses 2 ist an dem kürzeren Grifftragrohr 10 beispielsweise wiederum mittels einer durch eine Bohrung 25' eingebrachten Schraube gesichert.A top view of a modified embodiment of a housing 21 'of the coin deposit lock 2 is shown in FIG. 8, on which a receptacle 22' corresponding to the receptacle 22 in FIG. 1 is formed as an integrated part, on which the handle 5 is held and is secured accordingly if necessary. At the end of the housing 21 ′ facing a shorter handle support tube 10, the latter has a recess adapted to this handle support tube 10 8 'on. The housing 21 'of the coin deposit lock 2 is secured to the shorter handle support tube 10 again, for example, by means of a screw introduced through a bore 25'.

In Fig.9 ist schließlich noch eine Ausführungsform eines nicht näher dargestellten Einkaufswagens angedeutet, welcher zwei kurze Grifftragarme 1 aufweist. Hierbei ist an dem einen in Fig.9 weiter vorne liegenden Grifftragarm 1 ein Münzpfandschloß 2 beispielsweise in der Weise befestigt, wie in Verbindung mit der in Fig.4 dargestellten Ausführungsform im einzelnen beschrieben ist. Zur Halterung und Sicherung des Griffes 5 an dem anderen, in Fig.9 weiter hinten liegenden kurzen Grifftragarm 1 ist an dessen vorderen Ende ein dem Gehäuse 21 des Münzpfandschlosses 2 in den Abmessungen im wesentlichen entsprechendes, spiegelbildlich ausgebildetes Adapterteil 4 befestigt, mit welchem in bekannter Weise der rohrförmige Griff 5 fest verschraubt ist.Finally, FIG. 9 shows an embodiment of a shopping trolley, not shown, which has two short handle support arms 1. In this case, a coin deposit lock 2 is fastened to the handle support arm 1 located further forward in FIG. 9, for example in the manner described in detail in connection with the embodiment shown in FIG. In order to hold and secure the handle 5 on the other short handle support arm 1, which is located further back in FIG. 9, an adapter part 4, which corresponds essentially to the housing 21 of the coin deposit lock 2 in terms of dimensions, is fastened at its front end, with which in a known manner Way, the tubular handle 5 is screwed tight.
