Description

Die Erfindung betrifft einen Rollcontainer mit einem auf Lenkrollen und über einen Fußschalter blockierbaren Bockrollen laufenden Containergehäuse, das wenigstens ein Schubfach aufweist, in dem ein Schubkasten herausziehbar gehalten ist.The invention relates to a roll container with a container housing running on swivel castors and blockable castors which can be locked by means of a foot switch, which has at least one drawer in which a drawer is held so that it can be pulled out.

Rollcontainer dieser Art sind auf Rollen bewegbare Unterbauten, beispielsweise für Schreib- oder Labortische, die in der Regel mit mehreren in Schubfächern herausziehbar geführten Schubkästen versehen sind.Roll containers of this type are substructures that can be moved on rollers, for example for desks or laboratory desks, which are generally provided with a plurality of drawers which can be pulled out in drawers.

Ein Beispiel eines derartigen bekannten Rollcontainers ist in Fig. 2 der zugehörigen Zeichnung dargestellt.An example of such a known roll container is shown in Fig. 2 of the accompanying drawing.

Der in Fig. 2 dargestellte Rollcontainer 10 umfaßt ein Containergehäuse, in dem mehrere Schubkästen 40 herausziehbar geführt sind. Das Containergehäuse läuft auf Rollen 20 und 30, von denen wenigstens eine vordere Rolle 30 über einen integrierten Fußschalter blockierbar ist.The roll container 10 shown in Fig. 2 comprises a container housing in which a plurality of drawers 40 are guided to be pulled out. The container housing runs on rollers 20 and 30, of which at least one front roller 30 can be blocked via an integrated foot switch.

Bei einem plötzlichen Anhalten des Containers 10 können alle Schubkästen 40 gleichzeitig herausfahren, was dazu führen kann, daß der Container durch die Ausladung der Schubkästen 40 umfällt.If the container 10 suddenly stops, all the drawers 40 can move out at the same time, which can result in the container falling over due to the unloading of the drawers 40.

Normalerweise wird ein gleichzeitiges Herausziehen von mehreren Schubkästen 40 über eine Wechselauszugssperre verhindert, wie sie in Fig. 2 dargestellt ist. Diese Wechselauszugssperre bewirkt beim Herausziehen eines Schubkastens 40, daß eine Schließstange 90 angehoben wird, die dann alle anderen Schubkästen 40 blockiert. Wechselausgangssperren der dargestellten Art mit einem Anschlag mit Führungsbahn 100 sind an sich bekannt.Normally, a plurality of drawers 40 are prevented from being pulled out simultaneously by means of an interchangeable pull-out lock, as is shown in FIG. 2. When a drawer 40 is pulled out, this interchangeable pull-out lock causes a locking bar 90 to be raised, which then blocks all other drawers 40. Interchangeable exit barriers of the type shown with a stop with guide track 100 are known per se.

Derartige Wechselauszugssperren sind jedoch dann, wenn der Rollcontainer plötzlich angehalten wird, unwirksam, da bei einem plötzlichen Anhalten des Rollcontainers mehrere Schubkästen 40 gleichzeitig herausfahren. Wechselauszugssperren sind jedoch nur dann wirksam, wenn ein Schubkasten 40 vor den anderen herausfährt.Such interchangeable pull-out locks are, however, ineffective if the roll container is suddenly stopped, since several drawers 40 move out at the same time if the roll container suddenly stops. Removable pull-out locks are only effective if one drawer 40 moves out in front of the other.

Aus der DE-A-2724902 ist ein Möbel mit Schubladen bekannt, wobei ein Gesperre vorgesehen ist zum Verhindern des Öffnens der Schubladen. Das Gesperre bildet einen selbständigen Mechanismus, der sich für herkömmliche Standmöbel eignet.From DE-A-2724902 a piece of furniture with drawers is known, a locking mechanism being provided to prevent the drawers from opening. The locking mechanism forms an independent mechanism that is suitable for conventional stand furniture.

Die der Erfindung zugrundeliegende Aufgabe besteht daher darin, den Rollcontainer der eingangs genannten Art so auszubilden, daß keine Gefahr besteht, daß bei einem plötzlichen Anhalten der Schubkasten herausfährt.The object on which the invention is based is therefore to design the roll container of the type mentioned at the outset in such a way that there is no risk of the drawer moving out in the event of a sudden stop.

Diese Aufgabe wird gemäß der Erfindung durch eine mit dem Fußschalter gekoppelte Einrichtung gelöst, die den Schubkasten bei gelöstem Fußschalter blockiert, und bei betätigtem Fußschalter freigibt.This object is achieved according to the invention by a device coupled to the foot switch, which blocks the drawer when the foot switch is released and releases it when the foot switch is actuated.

Durch die erfindungsgemäße Ausbildung wird somit sichergestellt, daß bei gelöstem Fußschalter, d.h. dann, wenn der Rollcontainer umherfahren kann, da die blockierbaren Bockrollen nicht blockiert sind, ein Herausfahren des Schubkastens unmöglich ist, so daß auch bei einem plötzlichen Anhalten des Rollcontainers aufgrund der Trägheitskraft der Schubkasten nicht unbeabsichtigt herausfahren kann und den Rollcontainer zum Umkippen bringen kann, was insbesondere dann möglich wäre, wenn mehrere Schubkästen gleichzeitig ausfahren. Wenn der Fußschalter blockiert ist, d.h. wenn der Rollcontainer nicht umherfahren kann, dann ist der Schubkasten freigegeben, so daß er je nach Wunsch herausgezogen werden kann, wobei dann gegebenenfalls eine an sich bekannte Wechselauszugssperre bei mehreren vorgesehenen Schubkästen wirksam sein kann.The design according to the invention thus ensures that when the foot switch is released, ie when the mobile container can move around, because the lockable Fixed castors are not blocked, pulling out the drawer is impossible, so that even if the roll container suddenly stops due to the inertia, the drawer cannot inadvertently move out and cause the roll container to tip over, which would be possible in particular if several drawers extend at the same time. If the foot switch is blocked, ie if the mobile container cannot move around, then the drawer is released so that it can be pulled out as desired, in which case a known interchangeable pull-out lock can be effective if several drawer units are provided.

Ein besonders bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Rollcontainers ist Gegenstand des Schutzanspruches 2.A particularly preferred embodiment of the roll container according to the invention is the subject of claim 2.

Im folgenden wird anhand der zugehörigen Zeichnung ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben. Es zeigen

  • Fig. 1a und 1b teilweise geschnittene Seitenansichten des Ausführungsbeispiels des erfindungsgemäßen Rollcontainers mit freigegebenem und betätigtem Fußschalter und
  • Fig. 2a und 2b in teilweise geschnittenen Seitenansichten ein Ausführungsbeispiel eines bekannten Rollcontainers mit herausgezogenem Schubkasten und ohne einen herausgezogenen Schubkasten jeweils.
A particularly preferred exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawing. Show it
  • Fig. 1a and 1b partially sectioned side views of the embodiment of the roll container according to the invention with released and actuated foot switch and
  • 2a and 2b in partially sectioned side views an embodiment of a known roll container with a drawer pulled out and without a drawer pulled out, respectively.

Das in Fig. 1a und 1b dargestellte Ausführungsbeispiel des erfindungsgemäßen Rollcontainers umfaßt ein Containergehäuse, das auf vorzugsweise zwei Lenkrollen 20 und zwei Bockrollen 30 läuft, die über einen Fußschalter 110 blockierbar sind, um den Rollcontainer festzulegen, d.h. ein Umherfahren unmöglich zu machen. Im Containergehäuse sind mehrere Schubfächer vorgesehen, in denen Schubkästen 40 herausfahrbar gehalten oder geführt sind.The embodiment of the roll container according to the invention shown in Figs. 1a and 1b comprises a container housing, which preferably runs on two swivel castors 20 and two fixed castors 30, which can be blocked via a foot switch 110 in order to fix the roll container, i.e. making driving around impossible. A plurality of drawers are provided in the container housing, in which drawers 40 are held or guided so that they can be pulled out.

An einer Seite des in Fig. 1 dargestellten Rollcontainers ist eine Schließstange 60 angeordnet, die über ein Umlenkgestänge 80 mit dem Fußschalter 110 an einer vorderen Bockrolle 30 gekoppelt ist. An der Schließstange 60 sind mehrere Schließnocken 70 auf einer derartigen Höhe angebracht, daß sie Anschlägen 50 gegenüberliegen können, die an den Schubkastenseiten angeordnet sind. Die Schließnocken 70 und die Anschläge 50 liegen einander in Richtung des Ausfahrens der Schubkästen 40 dann gegenüber, wenn die Schließstange 60 angehoben ist, was dann der Fall ist, wenn der Fußschalter 110 gelöst ist, und somit die blockierbare Bockrolle 30 freigegeben ist, um mit dem Rollcontainer umherzufahren. Die Verbindung der Schließstange 60 mit dem Fußschalter 110 über das Umlenkgestänge 80 ist so ausgebildet, daß bei betätigtem Fußschalter 110, d.h. blockierter Bockrolle, die Schließstange 60 soweit abgesenkt ist, daß die Anschläge 50 von den Schließnocken 70 freigegeben sind, d.h. sich die Schließnocken 70 unterhalb der Laufbahn der Anschläge 50 beim Herausfahren der Schubkästen 40 befinden.On one side of the roll container shown in Fig. 1 a locking rod 60 is arranged, which is coupled to the foot switch 110 on a front fixed castor 30 via a deflection linkage 80. A plurality of locking cams 70 are attached to the locking rod 60 at a height such that they can lie opposite stops 50 which are arranged on the drawer sides. The locking cams 70 and the stops 50 face each other in the direction of the extension of the drawers 40 when the locking rod 60 is raised, which is the case when the foot switch 110 is released, and thus the blockable fixed roller 30 is released, to be able to to drive around the roll container. The connection of the locking rod 60 with the foot switch 110 via the deflecting linkage 80 is designed such that when the foot switch 110 is actuated, ie the fixed castor is blocked, the locking rod 60 is lowered to such an extent that the stops 50 are released by the locking cams 70, ie the locking cams 70 are located below the track of the stops 50 when the drawers 40 are moved out.

Das oben beschriebene Ausführungsbeispiel des erfindungsgemäßen Rollcontainers arbeitet in der folgenden Weise.The embodiment of the roll container according to the invention described above works in the following manner.

Wenn die Bockrolle 30 durch den Fußschalter 110 blockiert ist, dann befindet sich die Schließstange 60 in der unteren abgesenkten Lage, so daß die Schubkästen 40 herausgezogen werden können, da die Schließnocken 70 auf einer Höhe angeordnet sind, die unter der Bewegungsebene der Anschläge 50 an den Schubkästen liegt. Wenn der Fußschalter 110 nicht betätigt ist und somit die Bockrolle 30 freigegeben ist, um mit dem Rollcontainer umherzufahren, dann ist über das Umlenkgestänge 80 die Schließstange 70 angehoben, so daß die Schließnocken 70 den Anschlägen 50 gegenüber angeordnet sind, und somit ein Herausziehen der Schubkästen 40 durch die Ineingriffnahme zwischen den Schließnocken 70 und den Anschlägen 50 blockiert ist. Bei einem abrupten Anhalten des Rollcontainers sind daher alle Schubkästen 40 blockiert, ein plötzliches Herausfahren der Schubkästen 40 wird damit vermieden.If the fixed castor 30 is blocked by the foot switch 110, then the locking bar 60 is in the lower lowered position so that the drawers 40 can be pulled out, since the locking cams 70 are arranged at a level which is below the plane of movement of the stops 50 the drawers. If the foot switch 110 is not actuated and thus the fixed roller 30 is released in order to move around with the roller container, then the locking rod 70 is raised via the deflecting linkage 80, so that the locking cams 70 are arranged opposite the stops 50, and thus pulling out the drawers 40 is blocked by the engagement between the locking cam 70 and the stops 50. If the roll container stops abruptly, all drawers 40 are therefore blocked, one sudden removal of the drawers 40 is thus avoided.

Das oben beschriebene Ausführungsbeispiel des erfindungsgemäßen Rollcontainers kann in an sich bekannter Weise zusätzlich auch mit einer Wechselauszugssperre versehen sein, die in Fig. 2 dargestellt ist und bei mehreren Schubkästen normalerweise verhindert, daß ein Herausziehen von mehr als einem Schubkasten möglich ist. Eine derartige Wechselauszugssperre ist dann wirksam, wenn der Fußschalter 110 betätigt ist, so daß die bei dem erfindungsgemäßen Rollcontainer vorgesehene Schließstange 70 abgesenkt ist und somit die Schubkästen an sich herausziehbar wären.The above-described embodiment of the roll container according to the invention can also be provided in a manner known per se with an interchangeable pull-out lock, which is shown in FIG. 2 and normally prevents multiple drawers from pulling out more than one drawer. Such an interchangeable pull-out lock is effective when the foot switch 110 is actuated, so that the locking rod 70 provided in the roll container according to the invention is lowered and the drawers themselves could thus be pulled out.
