Abstract

At least two locking elements (12,14), shaped as flat, quarter-circle-shaped plates, are fixed next to each other on a lifting truck (50). The movement of the first locking element (12) is transmitted in the opposite direction to the second locking element (14). The locking elements fit from different sides into the holder element (30) to which they are tightly joined in a locking position. The transmission elements are in the form of outward-pointing teeth (24) on the locking elements, which each rotate on their own axle (15,16).

Description

Die vorliegende Erfindung bezieht sich auf eine Verriegelungsvorrichtung gemäß dem Oberbegriff im Anspruch 1.The present invention relates to a locking device according to the preamble of claim 1.

Mit solchen Verriegelungsvorrichtungen werden zwei nebeneinander angeordnete Hubwagen von Hubkipp- oder Kippvorrichtungen miteinander verriegelt, wie sie beispielsweise an Müllfahrzeugen verwendet werden, um Müllbehälter verschiedener Größe in das Müllfahrzeug zu entleeren.With such locking devices, two lift trucks arranged next to one another are locked together by lifting and tipping devices, as are used, for example, on refuse collection vehicles in order to empty waste containers of different sizes into the refuse collection vehicle.

Diese Müllbehälter werden in Kämme eingehängt, die am oberen Ende der Hubwagen angeordnet sind, von diesen Hubwagen anschließend angehoben und gekippt, so daß sich der Inhalt der Müllbehälter in das Müllfahrzeug entleert. Üblicherweise sind an diesen Müllfahrzeugen zwei Hubwagen nebeneinander angeordnet, wobei die Hubwagen so ausgebildet sind, daß sie jeweils einen üblichen Hausmüllbehälter, eine sogenannte Mülltonne, aufnehmen können. Um nun einen großen Hausmüllbehälter, einen sogenannten Müllcontainer, in das Müllfahrzeug entleeren zu können, werden diese beiden Hubwagen miteinander verriegelt. In die Kämme der miteinander verriegelten Hubwagen wird dann der Müllcontainer eingehängt und durch die miteinander verbundenen Hubwagen, die sich nun wie ein Hubwagen bewegen, angehoben und in das Müllfahrzeug entleert. Andere Großbehälter, die nicht mit ihrem Rand eingehängt werden, sondern Zapfen an den Seiten aufweisen, werden von zwei schwenkbaren Armen erfaßt und angehoben.These waste containers are hung in combs which are arranged at the upper end of the pallet truck, then lifted and tilted by these pallet trucks, so that the contents of the waste containers are emptied into the refuse vehicle. Usually two pallet trucks are arranged next to one another on these refuse collection vehicles, the pallet trucks being designed in such a way that they can each accommodate a normal household waste container, a so-called rubbish bin. In order to be able to empty a large household waste container, a so-called garbage container, into the garbage truck, these two pallet trucks are locked together. The garbage container is then hooked into the combs of the interlocked pallet trucks and raised by the linked pallet trucks, which now move like a pallet truck, and emptied into the garbage truck. Other large containers, which are not hung with their edges, but have pins on the sides, are gripped and lifted by two swivel arms.

Eine derartige Vorrichtung zum Verriegeln von nebeneinander angeordneten Hubwagen ist aus der DE-A-31 23 191 bekannt. Die darin offenbarte Verriegelungsvorrichtung weist einen Verbindungsstift bzw. Sperrstift auf, der beweglich auf einem Hubwagen befestigt ist und mittels eines Pneumatik- oder Hydraulikzylinders entlang seiner Achse verschoben wird, um in eine Ausnehmung auf dem anderen Hubwagen einzugreifen und die beiden Hubwagen miteinander zu verkoppeln. Die Betätigung des Pneumatik- oder Hydraulikzylinders kann dabei automatisch durch Verschwenken der Schwenkarme in Arbeitsposition oder durch Handbetätigung eines Steuerventils erfolgen.Such a device for locking lift trucks arranged side by side is known from DE-A-31 23 191. The locking device disclosed therein has a connecting pin or locking pin which is movably attached to a pallet truck and is displaced along its axis by means of a pneumatic or hydraulic cylinder in order to engage in a recess on the other pallet truck and to couple the two pallet trucks together. The actuation of the pneumatic or Hydraulic cylinders can be done automatically by swiveling the swivel arms into the working position or by manually operating a control valve.

Durch diese Verbindung in Form einer Steckverbindung wird eine Bewegung der Hubwagen relativ zueinander in Schwenkrichtung verhindert, sie können sich also nur als eine geschlossene Einheit in Schwenkrichtung bewegen. Ein wesentlicher Nachteil dieser bekannten Verriegelungsvorrichtung ist jedoch, daß die Hubwagen eine Querbewegung relativ zueinander durchführen können, sich also senkrecht zur Schwenkrichtung voneinander wegbewegen können. Dieses hat zur Folge, daß diese bekannt Verriegelungsvorrichtung kein Torisionsmoment in der Hubwagenebene übertragen kann, wie es beispielsweise durch die außermittige Krafteinbringung in die Hubwagen durch die in die schwenkbaren Arme eingehängten Großbehälter entsteht. Dadurch können sich die Hubwagen gegeneinander verdrehen, so daß im ungünstigsten Fall die Großbehälter mit ihren Zapfen aus den Aufnahmen der Schwenkarme rutschen und herabfallen und zerstört werden oder die gesamt Hubkipp-Vorrichtung blockieren. Aber auch bei den in die Kämme der Hubwagen eingehängten Müllcontainern können sich die Hubwagen voneinander wegbewegen und im ungünstigsten Fall die an den Müllcontainern angebrachten Aufhängevorrichtungen zerstören mit den oben geschilderten Folgen.This connection in the form of a plug-in connection prevents movement of the lifting trucks relative to one another in the pivoting direction, that is to say they can only move in the pivoting direction as a closed unit. A major disadvantage of this known locking device is, however, that the lifting trucks can carry out a transverse movement relative to one another, that is to say they can move away from one another perpendicular to the pivoting direction. The result of this is that this known locking device cannot transmit a torque in the pallet truck level, as occurs, for example, due to the eccentric application of force in the pallet truck through the large containers suspended in the pivotable arms. This allows the pallet trucks to rotate against each other, so that in the worst case, the large containers with their pins slide out of the receptacles of the swivel arms and fall down and are destroyed or block the entire lifting and tipping device. But also with the rubbish containers suspended in the combs of the pallet trucks, the pallet trucks can move away from one another and, in the worst case, destroy the hanging devices attached to the dumpsters with the consequences described above.

Vor diesem Hintergrund ist es nun Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Verriegeln von nebeneinanderliegenden Hubwagen von Hubkipp- oder Kippvorrichtungen zum Entleeren von Müllbehältern unterschiedlicher Größe zur Verfügung zu stellen, die die Hubwagen derart miteinander verbindet, daß sowohl eine Bewegung der Hubwagen relativ zueinander in Schwenkrichtung, als auch eine Bewegung der Hubwagen relativ zueinander senkrecht zur Schwenkrichtung verhindert wird, und die ein Torsionsmoment in der Hubwagenebene aufnehmen kann.Against this background, it is an object of the present invention to provide a device for locking adjacent pallet trucks from lift-tipping or tipping devices for emptying garbage containers of different sizes, which connects the pallet trucks with each other in such a way that both a movement of the pallet trucks relative to one another Swivel direction, as well as a movement of the pallet truck relative to each other perpendicular to the pivot direction is prevented, and which can absorb a torsional moment in the plane of the pallet truck.

Diese Aufgabe wird gelöst, indem mindestens zwei Verriegelungselemente benachbart auf einem Hubwagen beweglich befestigt sind, wobei die Bewegung des ersten Verriegelungselementes durch Übertragungsmittel gegensinnig auf das zweite Verriegelungselement übertragen wird, die Verriegelungselemente von verschiedenen Seiten in das Halteelement eingreifen und in Verriegelungsstellung die Verriegelungselemente mit dem Halteelement eine formschlüssige Verbindung herstellen. Durch die gegensinnige Übertragung der Bewegung des ersten Verriegelungselementes auf das zweite Verriegelungselement wird zum einen erreicht, daß zum Betätigen der Verriegelungsvorrichtung nur ein Verriegelungselement bewegt werden muß, beispielsweise von Hand, und zum anderen wird erreicht, daß die beiden Verriegelungselemente von verschiedenen Seiten in das Halteelement eingreifen, welches auf dem benachbarten Hubwagen angeordnet ist, wodurch in der Verriegelungsstellung eine formschlüssige Verbindung zwischen den Verriegelungselementen und dem Halteelement und damit zwischen den beiden Hubwagen hergestellt wird. Es wird somit eine Verriegelungsvorrichtung geschaffen, die in Verriegelungsstellung im wesentlichen einer starren Vierpunkt-Befestigung entspricht, so daß auch Torsionsbewegungen wirksam verhindert werden können.This object is achieved in that at least two locking elements are movably attached adjacent to a pallet truck, the movement of the first locking element being transmitted in opposite directions to the second locking element by means of transmission, the locking elements engage in the holding element from different sides, and in the locking position the locking elements with the holding element establish a positive connection. Through the opposite transmission of the movement of the first locking element to the second locking element, on the one hand it is achieved that only one locking element has to be moved, for example by hand, to actuate the locking device, and on the other hand it is achieved that the two locking elements from different sides into the holding element intervene, which is arranged on the adjacent pallet truck, whereby a positive connection between the locking elements and the holding element and thus between the two pallet trucks is made in the locking position. A locking device is thus created which, in the locking position, corresponds essentially to a rigid four-point fastening, so that torsional movements can also be effectively prevented.

In einer bevorzugten Ausführungsform bestehen die Übertragungsmittel aus Zähnen, die auf den Verriegelungselementen angeordnet sind. Durch die Nutzung von Zähnen als Übertragungsmittel ist ein einfaches, problemloses gegensinniges Übertragen der Bewegung des ersten Verriegelungselementes auf das zweite Verriegelungselement möglich, wobei gleichzeitig auch große Kräfte aufgenommen werden können.In a preferred embodiment, the transmission means consist of teeth which are arranged on the locking elements. Through the use of teeth as a transmission means, a simple, problem-free transmission of the movement of the first locking element to the second locking element is possible, wherein large forces can also be absorbed at the same time.

In einer weiteren Ausbildung sind die Zähne ständig in Eingriff miteinander, wodurch die Lage der Verriegelungselemente zueinander immer genau definiert und gleichzeitig fixiert ist.In a further embodiment, the teeth are constantly in engagement with one another, as a result of which the position of the locking elements relative to one another is always precisely defined and at the same time fixed.

Gemäß einer Ausführungsform bestehen die Verriegelungselemente jeweils aus einer flachen Platte mit einer im wesentlichen viertelkreisförmigen Gestalt. In einer besonders bevorzugten Ausführungsform sind die Zähne am Umfangsbogen, der im wesentlichen viertelkreisförmigen Verriegelungselemente angeordnet und zeigen nach außen, so daß die Verriegelungselemente im wesentlichen einen Sektor eines Stirnzahnrades bilden.According to one embodiment, the locking elements each consist of a flat plate with a substantially quarter-circular shape. In In a particularly preferred embodiment, the teeth are arranged on the circumferential arc, the essentially quarter-circular locking elements and point outwards, so that the locking elements essentially form a sector of a spur gear.

Vorzugsweise sind die Verriegelungselemente jeweils drehbar auf einer eigenen, senkrecht zu ihrer Oberfläche stehenden Achse gelagert, wobei die Achsen der Verriegelungselemente parallel zueinander stehen und so angeordnet sind, daß sich der Wälzkreis der Zähne des ersten Verriegelungselementes und der Wälzkreis der Zähne des zweiten Verriegelungselementes in einem Punkt berühren und die Zähne der beiden Verriegelungselemente somit ständig im Eingriff miteinander sind.Preferably, the locking elements are each rotatably mounted on their own axis perpendicular to their surface, the axes of the locking elements being parallel to one another and being arranged such that the pitch circle of the teeth of the first locking element and the pitch circle of the teeth of the second locking element are in one Touch point and the teeth of the two locking elements are thus constantly in engagement with each other.

Vorteilhafterweise sind die Achsen der Verriegelungselemente senkrecht übereinander und senkrecht zur Hubwagenebene so auf dem ersten Hubwagen angeordnet, daß die Verriegelungselemente in Ruhestellung mit ihrer Geraden, dem zweiten Hubwagen zugewandten Seite bündig mit der Kante des ersten Hubwagens abschließen. Durch diese Anordnung der Verriegelungselemente wird zum einen erreicht, daß die Verriegelungselemente mit ihrer Oberfläche parallel zur Hubwagenebene liegen und sich parallel zur Hubwagenebene verdrehen, und zum anderen wird erreicht, daß sie sich in Ruhestellung räumlich nicht über den Umlang des Hubwagens erstrecken und somit keine hervorstehenden Teile das Einhängen der Müllbehälter in den Hubwagen erschweren oder die Bewegung des anderen Hubwagens behindern.The axes of the locking elements are advantageously arranged vertically one above the other and perpendicular to the pallet truck level on the first pallet truck in such a way that the locking elements are flush with the edge of the first pallet truck in the rest position with their straight side facing the second pallet truck. This arrangement of the locking elements ensures, on the one hand, that the locking elements lie with their surface parallel to the pallet truck plane and twist parallel to the pallet truck plane, and secondly that, in the rest position, they do not spatially extend over the circumference of the pallet truck and thus do not protrude Parts make it difficult to hang the waste containers in the pallet truck or hinder the movement of the other pallet truck.

In einer bevorzugten Ausführungsform weist das Halteelement Bolzen mit einem Flansch am freien Ende auf, wobei die Längsachse der Bolzen parallel zu den Drehachsen der Verriegelungselemente angeordnet sind, wenn sich die Hubwagen in der gleichen Position befinden. Vorteilhafterweise besteht das Halteelement aus einem Teil des Rahmens des zweiten Hubwagens, auf dem die Bolzen senkrecht übereinander und senkrecht zur Hubwagenebene angeordnet sind.In a preferred embodiment, the holding element has bolts with a flange at the free end, the longitudinal axis of the bolts being arranged parallel to the axes of rotation of the locking elements when the lifting trucks are in the same position. The holding element advantageously consists of a part of the frame of the second pallet truck on which the bolts are arranged vertically one above the other and perpendicular to the plane of the pallet truck.

Vorzugsweise weisen die Verriegelungselemente Ausnehmungen auf, in die die Bolzen des Halteelementes eingreifen, wenn sich die Verriegelungselemente in der Verriegelungsstellung befinden. Vorteilhafterweise sind die Ausnehmungen an der geraden, in Ruhestellung dem zweiten Hubwagen zugewandten Seite, angeordnet.The locking elements preferably have recesses into which the bolts of the holding element engage when the locking elements are in the locking position. The recesses are advantageously arranged on the straight side facing the second pallet truck in the rest position.

Gemäß einer Ausführungsform sind die Verriegelungselemente in Ruhestellung und in Verriegelungsstellung arretierbar.According to one embodiment, the locking elements can be locked in the rest position and in the locking position.

In einer bevorzugten Ausführungsform ist das Betätigungselement gleichzeitig als Arretierungsvorrichtung ausgebildet. Vorteilhafterweise ist das Betätigungselement als Hebel ausgebildet, der am Rande des ersten Verriegelungselementes in einem Abstand von dessen Drehachse befestigt ist, so daß ein Hebelarm zum Drehen des Verriegelungselementes resultiert, und steht senkrecht von dessen Oberfläche hervor.In a preferred embodiment, the actuating element is simultaneously designed as a locking device. The actuating element is advantageously designed as a lever which is attached to the edge of the first locking element at a distance from the axis of rotation thereof, so that a lever arm results for rotating the locking element, and protrudes perpendicularly from its surface.

Gemäß einer besonderen bevorzugten Ausführungsform weist das Betätigungselement ein federbelastetes Griffelement auf, das in der Ruhestellung und in der Verriegelungsstellung in Ausnehmungen eines am ersten Hubwagen befestigten Arretierungselementes eingreift. Vorteilhafterweise ist dieses federbelastete Griffelement konzentrisch auf dem das Betätigungselement bildenden Hebel angeordnet und wird durch die Federbelastung in Richtung auf das Verriegelungselement gedrückt. Vorzugsweise weist das Arretierungselement zwei Ausnehmungen auf, die jeweils in den Endpunkten des Schwenkweges des Betätigungshebels angeordnet sind und die Schwenkbeweguugen des Betätigungshebels begrenzen. In diese Ausnehmungen des Arretierungselementes greift das Griffelement mit seiner dem Verriegelungselement zugewandten Seite ein, so daß die Verriegelungselemente in Ruhestellung und in Verriegelungsstellung arretierbar sind.According to a particularly preferred embodiment, the actuating element has a spring-loaded grip element which, in the rest position and in the locking position, engages in recesses in a locking element fastened to the first lifting truck. This spring-loaded grip element is advantageously arranged concentrically on the lever forming the actuating element and is pressed in the direction of the locking element by the spring load. The locking element preferably has two recesses, which are each arranged in the end points of the pivoting path of the actuating lever and limit the pivoting movements of the actuating lever. The handle element engages with its side facing the locking element in these recesses of the locking element, so that the locking elements can be locked in the rest position and in the locking position.

Um beide Hubwagen miteinander zu verbinden, ist im mittleren Bereich der Hubwagen 50, 52 eine Verriegelungsvorrichtung 10 angeordnet, die in Figur 1 im unverriegelten Zustand dargestellt ist.FIG. 1 shows the rear view of a lifting and tipping device, in which essentially only the two lifting trucks 50, 52 arranged next to one another are shown. In the upper area of the lifting trucks 50, 52 there are receiving combs 56 with teeth pointing upwards for hanging garbage containers. The lifting trucks are each equipped with a swivel arm 57 to accommodate garbage containers provided with lateral pins. In order to connect the two lifting trucks to one another, a locking device 10 is arranged in the central region of the lifting trucks 50, 52, which is shown in FIG. 1 in the unlocked state.

Die Verriegelungsvorrichtung 10, die im Detail in Figur 3 zu sehen ist, weist zwei plattenförmige Verriegelungselemente 12, 14 von im wesentlichen viertelkreisförmiger Gestalt auf, die schwenkbar auf dem ersten Hubwagen 50 angeordnet sind, und in Verriegelungsstellung in Bolzen 32 eines Halteelementes 30 eingreifen, welches auf dem zweiten Hubwagen 52 angeordnet ist. Die Verriegelungselemente 12, 14 sind jeweils auf eigenen horizontal angeordneten Achsen 15, 16 drehbar gelagert, wobei die Achsen 15, 16 parallel zueinander und senkrecht zur Hubwagenebene übereinander auf dem Rahmen 58 des ersten Hubwagen 50 angeordnet sind, so daß die plattenförmigen Verriegelungselemente 12, 14 parallel zur Hubwagenebene verschwenken. Das erste Verriegelungselement 12 wird durch ein Betätigungselement 42 bewegt, wobei die Bewegung des ersten Verriegelungselementes 12 durch Übertragungsmittel gegensinnig auf das zweite Verriegelungselement 14 übertragen wird. In der hier beschriebenen Ausführungsform bestehen die Übertragungsmittel aus Zähnen 24, die auf den plattenförmigen Verriegelungselementen 12, 14 von im wesentlichen viertelkreisförmiger Gestalt am Bogenumfang angeordnet sind, so daß die Verriegelungselemente 12, 14 im wesentlichen die Form eines Zahnradsektors bilden. Die Zähne 24 der beiden Verriegelungselemente 12, 14 sind ständig in Eingriff, da die beiden Achsen 15, 16 der Verriegelungselemente 12, 14 so angeordnet sind, daß sich die Wälzkreise der beiden Zahnradsegmente in einem Punkt berühren. Weiterhin sind die Verriegelungselemente 12, 14 so auf dem ersten Hubwagen 50 angeordnet, daß sie in Ruhestellung mit ihrer geraden, dem zweiten Hubwagen zugewandten Kante 18, 19 bündig mit der Kante des ersten Hubwagens 50 abschließen, den Umfang des ersten Hubwagens 50 also nicht überragen, so daß sich beide Hubwagen 50, 52 unabhängig voneinander bewegen können.The locking device 10, which can be seen in detail in Figure 3, has two plate-shaped locking elements 12, 14 of substantially quarter-circular shape, which are pivotally arranged on the first lifting carriage 50, and engage in the locking position in the bolt 32 of a holding element 30, which is arranged on the second pallet truck 52. The Locking elements 12, 14 are each rotatably mounted on their own horizontally arranged axes 15, 16, the axes 15, 16 being arranged parallel to one another and perpendicular to the pallet truck plane one above the other on the frame 58 of the first pallet truck 50, so that the plate-shaped locking elements 12, 14 are parallel swivel to the pallet truck level. The first locking element 12 is moved by an actuating element 42, the movement of the first locking element 12 being transmitted in opposite directions to the second locking element 14 by transmission means. In the embodiment described here, the transmission means consist of teeth 24 which are arranged on the plate-shaped locking elements 12, 14 of a substantially quarter-circular shape on the arc circumference, so that the locking elements 12, 14 essentially form the shape of a gear sector. The teeth 24 of the two locking elements 12, 14 are constantly engaged, since the two axes 15, 16 of the locking elements 12, 14 are arranged so that the rolling circles of the two gear segments touch at one point. Furthermore, the locking elements 12, 14 are arranged on the first pallet truck 50 in such a way that they rest flush with the edge of the first pallet truck 50 with their straight edge 18, 19 facing the second pallet truck, so that they do not protrude beyond the circumference of the first pallet truck 50 , so that both pallet trucks 50, 52 can move independently of each other.

Wenn nun das erste Verriegelungselement 12 mittels des Betätigungselementes 42 aus der Ruhestellung in Richtung auf den zweiten Hubwagen 52 verschwenkt wird, wird das zweite Verriegelungselement 14 gegensinnig, aber ebenfalls in Richtung auf den zweiten Hubwagen 52 verschwenkt (s. Figur 2). Auf dem zweiten Hubwagen 52 ist das Halteelement 30 angeordnet, welches zwei Bolzen 32 mit jeweils einem Flansch 34 am freien Ende aufweist, die auf dem Rahmen 59 befestigt sind. In diese Bolzen 32 greifen die Verriegelungselemente 12, 14 mit ihren Ausnehmungen 20, 22, welche an ihrer geraden, dem zweiten Hubwagen zugewandten Seite 18, 19 angeordnet sind, ein, wobei jedes Verriegelungselement 12, 14 jeweils in den ihm zugeordneten Bolzen 32 eingreift. Durch die gegensinnige Schwenkbewegung der Verriegelungselemente 12, 14 greifen diese dabei jeweils von verschiedenen, sich gegenüberliegenden Seiten in die Bolzen 32 des Halteelementes 30 ein, so daß eine formschlüssige Verbindung zwischen den beiden Hubwagen 50, 52 hergestellt wird.If the first locking element 12 is now pivoted from the rest position in the direction of the second pallet truck 52 by means of the actuating element 42, the second locking element 14 is pivoted in the opposite direction, but also in the direction of the second pallet truck 52 (see FIG. 2). The holding element 30 is arranged on the second pallet truck 52 and has two bolts 32, each with a flange 34 at the free end, which are fastened on the frame 59. The locking elements 12, 14 engage in these bolts 32 with their recesses 20, 22, which are arranged on their straight side 18, 19 facing the second lifting truck, each Locking element 12, 14 engages in the bolt 32 assigned to it. Due to the opposite pivoting movement of the locking elements 12, 14, they engage in each case from different, opposite sides in the bolts 32 of the holding element 30, so that a positive connection between the two lifting trucks 50, 52 is established.

Das erste Verriegelungselement 12 wird mittels eines Betätigungselementes in Form eines Hebels 42, an dem ein Griffelement 44 angeordnet ist, verschwenkt (Figur 4). Dieser Hebel 42 ist am Rand des ersten Verriegelungselementes 12 angeordnet und erstreckt sich senkrecht von der Oberfläche des Verriegelungselementes 12 nach außen, wobei das Griffelement 44 auf dem freien Ende des Hebels 42 konzentrisch angeordnet und so federbelastet ist, daß er in Richtung auf das Verriegelungselement 12 gedrückt wird. Dieses federbelastete Griffelement 44 bildet in Verbindung mit dem zweiten, auf dem ersten Hubwagen angeordneten Arretierungselement 46 die Arretierungsvorrichtung 40, mit der die Verriegelungsvorrichtung 10 in Ruhestellung und in Verriegelungsstellung arretiert wird. Dieses zweite Arretierungselement 46 weist zwei Ausnehmungen 48 auf, die so angeordnet sind, daß sie jeweils die Endpunkte des Schwenkweges 43 des Betätigungshebels 42 bilden, und in die der federbelastete Handgriff 44 mit seiner dem Verriegelungselement 12 zugewandten Seite somit in Ruhestellung und in Verriegelungsstellung eingreifen kann.The first locking element 12 is pivoted by means of an actuating element in the form of a lever 42 on which a grip element 44 is arranged (FIG. 4). This lever 42 is arranged on the edge of the first locking element 12 and extends perpendicularly outwards from the surface of the locking element 12, the handle element 44 being arranged concentrically on the free end of the lever 42 and being spring-loaded so that it is directed towards the locking element 12 is pressed. This spring-loaded handle element 44, in conjunction with the second locking element 46 arranged on the first lifting truck, forms the locking device 40 with which the locking device 10 is locked in the rest position and in the locking position. This second locking element 46 has two recesses 48 which are arranged so that they each form the end points of the pivot path 43 of the actuating lever 42, and in which the spring-loaded handle 44 with its side facing the locking element 12 can thus engage in the rest position and in the locking position .
