Definitions
- the invention relates to a trolley pallet for the transport of trolleys, which has runways for receiving the rollers of a trolley, which in the insertion direction of the trolley "behind" lying, the length of the insertion path limiting insertion limits, wherein between two tracks a subway tunnel is provided and, wherein to secure the trolleys positioned on the trolley pallet, a blocking device is provided which can be brought from a blocking position into a neutral starting position.
- Pallets for the transport of so-called trolleys have been known for some time. To this is exemplary on the WO 2009/090309 A1 as well as the DE 20 2006 007 202 U1 directed.
- the pallet consists of a welded construction, in particular of different welded together sheet metal components and has for receiving or for inserting the rollers corresponding raceways. In particular in the field of these tracks, these pallets consist of correspondingly bent sheet metal components. Between the raceways, these pallets form a so-called.
- Unterfahrtunnel in which, for example, a low-lift truck or a forklift can be retracted with his forks. By subsequently lifting the forks is Thus, the range lifted from the ground and can be transported, for example for loading accordingly by means of the pallet truck.
- a backup plate provided to secure the recorded trolley, which is arranged in the area of the subway tunnel. If two trolleys are to be taken in succession on the raceways, two such fuses are provided in this tunnel area, each of the fuses being assigned to one of the trolleys.
- the securing plate is formed as a sheet metal component and pivotable about a parallel to the raceways arranged pivot axis. Thus, this backup plate can be swung out of a neutral, approximately horizontal position with its free end up. In this free end region, this securing plate has an open locking slot, which can be brought into positive engagement with a transverse web accessible on the underside of the trolley.
- each pallet truck can be secured individually.
- a hand lever is provided in an end region, which is rotatably connected to the bearing shaft of the locking plates.
- it In order to perform a pivoting movement of this hand lever, it must first be “unlocked” in the axial direction to then rotate the bearing shaft of the locking plates to can.
- This is particularly complicated when fully loaded pallet handling, especially as this hand lever is necessarily located in the area of the substrate and thus difficult to access.
- the axial movement can only be performed by hand, so that the operator can handle this locking device only in squatting working position.
- From the DE 10 2009 052 869 A1 is a construction known for securing the trolley on a pallet, at which can be moved laterally into the region of the raceways below the upright trolley plate-shaped blocking devices into it.

Due to this "frontal" arrangement, the blocking device is accessible in an erected trolley in a simple manner. Furthermore, the blocking device has a blocking element, which may be formed, for example, as a transverse stop web, which is directed vertically upwards. This blocking element is in its blocking position in the path of movement of the bottom plate of a pushed onto the pallet trolley, so that it can no longer independently roll down from the trolley pallet. Since the blocking element is located in the path of movement of the bottom plate, it can be brought into blocking engagement with the bottom plate or with an end-side edge portion of the bottom plate in the blocking position.
- the blocking element is brought from its locking position to a neutral starting position, in which the blocking element is arranged completely below the bottom plate of the erected trolley. In this position, each trolley is thus in a simple manner extendable again from the trolley pallet.
- the neutral starting position can be locked. In a bottom flat floor plate, however, such a lock is not mandatory.

Des Weiteren weist die Blockiereinrichtung ein Sperrelement auf, welches beispielsweise als quer verlaufender Anschlagsteg ausgebildet sein kann, welcher vertikal nach oben gerichtet ist. Dieses Sperrelement liegt in seiner Sperrposition in der Bewegungsbahn der Bodenplatte eines auf der Palette aufgeschobenen Rollwagens, so dass dieser nicht mehr selbstständig von der Rollwagenpalette herunter rollen kann. Da das Sperrelement in der Bewegungsbahn der Bodenplatte liegt, kann dieses auch in der Sperrposition mit der Bodenplatte bzw. mit einem stirnseitigen Randabschnitt der Bodenplatte in sperrende Wirkverbindung gebracht werden.Thus, the blocking device according to the invention is arranged to the intake restrictions in the longitudinal direction of the trolley pallet opposite in the end region of the respective subway tunnel. Due to this "frontal" arrangement, the blocking device is accessible in an erected trolley in a simple manner. Furthermore, the blocking device has a blocking element, which may be formed, for example, as a transverse stop web, which is directed vertically upwards. This blocking element is in its blocking position in the path of movement of the bottom plate of a pushed onto the pallet trolley, so that it can no longer independently roll down from the trolley pallet. Since the blocking element is located in the path of movement of the bottom plate, it can be brought into blocking engagement with the bottom plate or with an end-side edge portion of the bottom plate in the blocking position.
Durch einfaches manuelles Niederdrücken wird das Sperrelement aus seiner Sperrposition in eine neutrale Ausgangsstellung gebracht, in welcher das Sperrelement vollständig unterhalb der Bodenplatte des aufgestellten Rollwagens angeordnet ist. In dieser Stellung ist somit jeder Rollwagen in einfacher Weise wieder aus der Rollwagenpalette ausfahrbar. Dabei ist erfindungsgemäß vorzugsweise die neutrale Ausgangsstellung arretierbar. Bei einer unterseitig ebenen Bodenplatte ist jedoch eine derartige Arretierung nicht zwingend notwendig.By simple manual depression, the blocking element is brought from its locking position to a neutral starting position, in which the blocking element is arranged completely below the bottom plate of the erected trolley. In this position, each trolley is thus in a simple manner extendable again from the trolley pallet. In this case, according to the invention, preferably the neutral starting position can be locked. In a bottom flat floor plate, however, such a lock is not mandatory.
Da die Blockiereinrichtung mit dem Stellhebel seines Sperrelementes in der neutralen Ausgangslage in den jeweiligen Unterfahrtunnel hineinragt, wird ein Verstellung der Blockiereinrichtung aus seiner Ausgangsstellung in die Sperrstellung insbesondere auch dadurch bewirkt, wenn die Rollwagenpalette mit den Gabeln eine Hubstapler oder dgl. angehoben wird, da diese Gabeln zum Anheben der Rollwagenpalette in den jeweiligen Unterfahrtunnel eingreifen und zwangsläufig beim Anheben den Stellhebel mit seinen Sperrelement vertikal nach oben drücken. Somit findet eine Sicherung der Rollwagen beim Transport stets zwangsläufig statt, selbst wenn eine Bedienperson vergessen haben sollte, vorab die Blockiereinrichtung manuell in ihre Sperrstellung zu bringen.Since the blocking device protrudes with the adjusting lever of its blocking element in the neutral starting position in the respective underpass tunnel, an adjustment of the blocking device from its initial position to the blocking position is in particular also effected by the trolley pallet with the forks a lift truck or the like. Is raised, as these Forks to raise the trolley pallet engage in the respective underpass tunnel and inevitably press the lever with its locking element vertically upward when lifting. Thus, a backup of the trolley during transport always inevitably takes place, even if an operator should have forgotten to advance to bring the blocking device manually in its locked position.
Weitere vorteilhafte Ausgestaltungen der Blockiereinrichtung bzw. der Rollwagenpalette sind den weiteren Unteransprüchen entnehmbar.Further advantageous embodiments of the blocking device or the trolley pallet are the further subclaims removed.
So kann gemäß Anspruch 2 vorgesehen sein, dass die Blockiereinrichtung in einer sich längs erstreckenden, nutartigen Vertiefung der oberen Begrenzungswand des Unterfahrtunnels angeordnet ist und, dass die Blockiereinrichtung in den seitlichen Randbereichen der Vertiefung schwenkbar gelagert. Diese Ausgestaltung ermöglicht eine äußerst einfache Herstellung und auch eine äußerst einfache Bedienung, da die Blockiereinrichtung frontseitig zugänglich ist. Dabei kann die Blockiereinrichtung auch einstückiger Bestandteil der oberen Begrenzungswand sein. In diesem Fall wir die obere Begrenzungswand im Bereich ihrer Vertiefung mit zwei seitlich voneinander beabstandeten Längsschlitzen versehen, so dass sich daraus zwangläufig ein aus einer Sperrposition in eine neutrale Ausgangslage bringbarer "Hebelabschnitt" ergibt, an dessen freiem Ende das Sperrelement angeordnet ist.Thus, it can be provided according to
Weiter kann gemäß Anspruch 3 vorgesehen sein, dass die Blockiereinrichtung mit ihrem Sperrelement durch Federelemente federelastisch nachgiebig in ihrer Sperrposition fixiert ist. Solche Federelemente können beispielsweise Schenkelfedern sein oder auch Axialdruckfedern, je nach Ausgestaltung der Rollwagenpalette bzw. des Unterfahrtunnels im Bereich der Blockiereinrichtung.Further, it can be provided according to claim 3, that the blocking device is fixed with its locking element by spring elements resiliently resilient in its locked position. Such spring elements may be, for example, leg springs or axial compression springs, depending on the configuration of the trolley pallet or the subway tunnel in the blocking device.
Weiter kann gemäß Anspruch 4 vorgesehen sein, dass zur Fixierung der neutralen Ausgangsstellung der Blockiereinrichtung federelastisch nachgiebige Arretierelemente vorgesehen sind. Solche Arretierelemente sind derart ausgestaltet, dass die Blockiereinrichtung nach dem "Niederdrücken" rastend fixiert sind, wobei die Rastwirkung derart ausgebildet ist, dass die Blockiereinrichtung manuell wieder vertikal nach oben gedrückt werden kann. Dementsprechend sind die Arretierelemente federelastisch nachgiebig ausgebildet. Durch diese Ausgestaltung wird insbesondere vorteilhaft erreicht, dass auch Rollwagen mit unterhalb der Bodenplatte angeordneten Querstegen in einfacher Weise aufgeschoben werden können, ohne dass eine Blockierung auftreten kann. Insbesondere können aber auch beim Ausfahren des jeweiligen Rollwagens diese Querstege nicht mit der Blockiereinrichtung in Eingriff gelangen, da die Blockiereinrichtung in ihrer vertikal nach unten gerichteten Ausgangsstellung arretiert ist.It can further be provided according to claim 4, that are provided for fixing the neutral starting position of the blocking device resiliently resilient locking elements. Such locking elements are designed such that the blocking device are fixed in a latching manner after the "depression", wherein the latching action is designed such that the blocking device can be pressed manually again vertically upwards. Accordingly, the locking elements are resiliently resilient. This embodiment is in particular achieved advantageous that even trolley can be pushed with arranged below the bottom plate transverse webs in a simple manner without blocking can occur. In particular, however, these transverse webs can not engage with the blocking device when the respective trolley is being extended, since the blocking device is locked in its vertical downwardly directed starting position.
Weiter kann gemäß Anspruch 5 vorgesehen sein, dass die Blockiereinrichtung in ihrer Sperrposition und ihrer Ausgangsstellung durch federelastisch nachgiebige Arretierelemente fixiert ist. Diese Ausgestaltung kann insbesondere alternativ zur Ausgestaltung nach Anspruch 3 vorgesehen sein. So wird die Blockiereinrichtung nach Anspruch 5 insbesondere in ihrer Sperrposition nicht federelastisch durch Federelemente gehalten, sondern durch eine nach Art einer Rastvorrichtung wirkenden Arretiervorrichtung. Dementsprechend sind auch die federelastisch nachgiebigen Arretierelemente in ihrer Formgebung auszugestalten.It can further be provided according to
Weiter kann gemäß Anspruch 6 vorgesehen sein, dass das Sperrelement der Blockiereinrichtung stirnseitig eine schräg nach oben "hinten" verlaufende Rampe bildet, welche beim Aufschieben eines Rollwagens mit der Bodenplatte des Rollwagens derart in Wirkverbindung bringbar ist, dass die Blockiereinrichtung mit ihrem Sperrelement beim Aufschieben des Rollwagens auf die Rollwagenpalette aus ihrer Sperrposition in ihre Ausgangsstellung verstellbar ist. Durch diese Ausgestaltung ist zum Aufschieben eines Rollwagens eine vorab manuelle Betätigung der Blockiereinrichtung nicht notwendig. Diese wird automatisch "niedergedrückt", sobald diese mit der Bodenplatte bzw. einer in Einfahrrichtung stirnseitig vorgesehenen Querkante der Bodenplatte des Rollwagens in Kontakt gelangt. Diese Ausgestaltung erlaubt es auch, Rollwagen mit unterseitig vorgesehenen Querstreben aufzuschieben, da auch bei Kontakt dieser Querstreben mit der "Rampe" die Blockiereinrichtung mit ihrem Sperrelement stets niedergedrückt wird, so dass ein Auffahren in einfacher Weise möglich ist. Diese Ausgestaltung ist insbesondere im Zusammenhang mit der Ausgestaltung nach Anspruch 3 zu sehen, nach welcher die Blockiereinrichtung durch Federelemente in ihrer Sperrposition federelastisch nachgiebig gehalten wird. Allerdings sollte in diesem Fall, um auch Rollwagen mit unterseitigen Querstreben in einfacher Weise wieder ausfahren zu können, die Ausgestaltung nach Anspruch 4 vorgesehen sein, wonach die Blockiereinrichtung durch die federelastisch nachgiebigen Arretierelemente in ihrer neutralen Ausgangsstellung gehalten wird.It can further be provided according to
Eine äußerst vorteilhafte Ausgestaltung ist durch die Merkmalskombination des Anspruchs 7 gegeben. Danach ist vorgesehen, dass das Sperrelement im beweglichen Endbereich eines als Stellhebel ausgebildeten Teils der Blockiereinrichtung angeordnet ist und, dass der Stellhebel in der neutralen Ausgangsstellung der Blockiereinrichtung nach unten in den zugehörigen Unterfahrtunnel hineinragt. Wie bereits eingangs erwähnt, dient eine solche Rollwagenpalette u. a. auch zum Transport von Rollwagen, welche auf die Rollwagenpalette aufgestellt sind. Hierzu werden regelmäßig beispielsweise Niederhubwagen oder Gabelstapler eingesetzt, welche mit den Gabelzinken ihrer "Hubgabel" in die Unterfahrtunnel einfahren können. Beim Anheben drücken somit die Gabelzinken gegen die Unterseite der oberen, in der Regel horizontal verlaufenden, Begrenzungswand des jeweiligen Unterfahrtunnels. Verbleibt nun die Blockiereinrichtung in ihrer neutralen Ausgangsstellung, sei es weil keine Federelemente für die Rückstellung vorgesehen sind oder weil beispielsweise die Rückstellfedern gebrochen sind und vergessen wurde diese in ihre Sperrstellung zu bringen, so werden die Blockiereinrichtungen jedes Unterfahrtunnels durch die sich vertikal aufwärts bewegenden Gabezinken zwangweise in ihre Sperrstellung verstellt, so dass insbesondere beim Transport der Rollwagen diese zwangsweise auf der Rollwagenpalette gesichert sind. Des Weiteren wird aber auch eine sich bereits in der Sperrstellung befindliche Blockiereinrichtung zusätzlich durch die entsprechende Gabelzinke gesichert, da die Gabelzinke während des Transports unterseitig am Stellhebel anliegt. Aber auch beim Transport auf einem LKW ist diese Ausgestaltung von Vorteil. In der Regel werden die sich auf der Rollwagenpalette befindenden Rollwagen für den LKW-Transport mittels eines alle Rollwagen oberseitig abdeckenden Deckels abgedeckt. Anschließend wird der Deckel - und somit auch die Rollwagen - mittels Spannbändern auf der Rollwagenpalette gesichert. Diese Spannbänder werden dabei längs durch die Unterfahrtunnel hindurch geführt und über den Deckel bzw. die Rollwagen gelegt. Beim Verspannen der Spannbänder wird somit ebenfalls eine vertikale Kraft auf die freien Endbereiche der Stellhebel mit ihren Sperrelement ausgeübt, so dass auch hierdurch eine zusätzliche Sicherung der Blockiereinrichtungen in ihrer jeweiligen Sperrstellung bewirkt wird. Da insbesondere beim Transport sei es mit einem Gabelstapler oder auf einem LKW die größten Beschleunigungskräfte auf die aufgestellten Rollwagen einwirken, ist durch die Ausgestaltung nach Anspruch 7 absolut sicher gestellt, dass sich die Blockiereinrichtungen nicht selbständig lösen können.An extremely advantageous embodiment is given by the feature combination of claim 7. Thereafter, it is provided that the blocking element is arranged in the movable end region of an actuating lever designed as part of the blocking device and that the actuating lever projects in the neutral starting position of the blocking device down into the associated subway tunnel. As already mentioned, such a trolley pallet serves, inter alia, for the transport of trolleys, which are placed on the trolley pallet. For this purpose, for example, low pallet truck or forklift are used, which with the forks of their "fork" can enter the underpass tunnel. When lifting so press the forks against the underside of the upper, usually horizontally extending, boundary wall of the respective subway tunnel. Remains now the blocking device in its neutral starting position, either because there are no spring elements for the provision or because, for example, the return springs are broken and forgot to bring them into their locked position, the blocking devices of each subway tunnel by the vertically upwardly moving dispensing tines forcibly adjusted in their blocking position, so that in particular during transport of the trolley these are forcibly secured on the trolley pallet. Furthermore, however, a blocking device already located in the blocking position is additionally secured by the corresponding fork prong, since the fork prong bears against the adjusting lever on the underside during transport. But even when transported on a truck, this configuration is beneficial. In general, located on the trolley pallet trolley for truck transport by means of a trolley covering the top cover are covered. Subsequently, the lid - and thus the trolleys - secured by means of straps on the trolley pallet. These straps are guided longitudinally through the underpass tunnel and placed over the lid or the trolley. When tightening the straps thus a vertical force is thus also exerted on the free end portions of the lever with its blocking element, so that also causes an additional backup of the blocking devices in their respective blocking position becomes. Since in particular when transporting it with a forklift truck or on a truck, the greatest acceleration forces acting on the erected trolley, is absolutely certain by the embodiment according to claim 7 that the blocking devices can not solve independently.
Anhand der Zeichnungen wird nachfolgend die Erfindung beispielhaft näher erläutert. Dabei ist die Erfindung nicht auf die konkret angegebenen Ausführungsformen beschränkt. Insbesondere kann die Rollwagenpalette auch zur Aufnahme von mehr oder weniger als vier Rollwagen ausgestaltet sein. Es zeigt:

Jeder dieser Unterfahrtunnels 6 und 7 weist etwa mittig eine sich beim vorliegenden Ausführungsbeispiel über die komplette Länge der Rollwagenpalette erstreckende, nutartige Vertiefung 8 bzw. 9 auf. Die vertikal nach oben vorstehenden Teile der oberen Begrenzungswand 10 bzw. 11 des jeweiligen Unterfahrtunnels 6 bzw. 7 sind durch insgesamt vier Querstege 12, 13, 14, 15 bzw. 16, 17, 18, 19 miteinander verbunden. Durch diese Ausgestaltung erhält insbesondere jede obere Begrenzungswand 10 bzw. 11 eine äußerst hohe Biegesteifigkeit.Each of these

Es ist erkennbar, dass die Blockiereinrichtung 24 über eine Lagerachse 25 schwenkbar an den vertikal ausgerichteten Seitenwänden 26 und 27 der Vertiefung 8 gelagert ist. Dabei ist die Blockiereinrichtung 24 als Blechbauteil ausgebildet, welches im Wesentlichen U-förmig ausgestaltet ist. Ausgehend von der Lagerachse 25 bildet die Blockiereinrichtung eine Art Stellhebel 28, in dessen vorderen Endbereich ein Sperrelement 29 angeordnet ist.It can be seen that the blocking
An dieser Stelle sei angemerkt, dass der Stellhebel 28 auch einstückiger Bestandteil der oberen Begrenzungswand 10 bzw. 11 sein kann. Hierzu ist es lediglich notwendig in einem entsprechenden seitlichen Abstand in der Vertiefung 8 bzw. 9 Längsschlitze anzubringen, so dass der Stellhebel 28 "ausgeschnitten" ist. Der Verbindungsbereich zwischen dem "ausgeschnittenen" Stellhebel bildet sodann eine Art federelastisches Schwenklager.It should be noted at this point that the adjusting

Auch kann diese Sperrposition beim Transport auf einem LKW zusätzlich gesichert werden, indem durch den Unterfahrtunnel ein Spannband hindurch geführt und um die aufgestellten Rollwagen gelegt wird. Das Spannband (in der Zeichnung nicht dargestellt) verläuft dabei zwangsläufig auch um den "freien" Endbereich des Stellhebels 28 mit seinem Sperrelement 29 herum und wird außenseitig vertikal nach oben geführt. Beim Spannen des Spannbandes wird somit die Blockiereinrichtung zwangsläufig ebenfalls in seiner Sperrposition gesichert, so dass auch bei größeren Beschleunigungswerten, welche beim LKW-Transport stets auftreten können, ein ungewolltes Lösen der Blockiereinrichtung 24 sicher ausgeschlossen ist.Also, this locking position can be additionally secured during transport on a truck by passing through the Unterfahrtunnel a strap and passed around the erected trolley. The strap (not shown in the drawing) inevitably runs around the "free" end portion of the actuating

Sobald das Sperrelement 29 sich in der in Phantomlinien 50 dargestellten neutralen Ausgangslage befindet, werden die federelastischen Arretierelemente 46 und 47 entsprechend entgegen der beiden Pfeile 51 bzw. 52 zurückgestellt, so dass diese mit ihren Sperrfingern 48 bzw. 49 an den Rankanten der Ausklinkung 45 sperrend anliegen. Auf Grund des rampenartigen, schräg geneigten Verlaufs der Sperrfinger 48 und 49, kann diese Sperrwirkung durch einfache manuelle Krafteinwirkung entgegen des Pfeiles 31 auf das Sperrelement 29 wiederum aufgehoben werden. Dabei bewegen sich die rampenartig ausgestalteten Sperrfinger 48 und 49 entlang der Rankanten der Ausklinkung 45 und werden wiederum in Richtung der Pfeile 51 bzw. 52 nach innen verstellt. Somit gelangt das Sperrelement 29 der Blockiereinrichtung 24 in einfacher Weise wieder in die in

Die Formgebung kann dabei beispielsweise so gewählt sein, dass die Arretierelemente 46, 47 auch mit ihrem im unteren Verbindungsbereich zum Sperrelement an den Randbereich "leicht rastend" oder nur klemmend anliegen, so dass die Sperrstellung ebenfalls fixiert ist.If no
