Description

Die Erfindung betrifft eine auf Stützen abstellbare Plattform mit unter dieser im Bereich der seitlichen Plattform-Längskanten beabstandet voneinander angeordneten und um Anlenkachsen aus ihren Stützpositionen in unterseitig an die Plattform angeklappte Nichtgebrauchsstellungen und umgekehrt verschwenkbaren Stützbeinen. Insbesondere betrifft die Erfindung eine Ladeplattform oder einen Kastenaufbau für Lastkraftwagen, die der wahlweise vom Trägerfahrzeug trennbar und auf Stützen abstellbar sind.The invention relates to a platform that can be placed on supports with under this spaced apart from one another in the region of the longitudinal longitudinal edges of the platform arranged and about pivot axes from their support positions in the underside Non-use positions folded onto the platform and vice versa Support legs. In particular, the invention relates to a loading platform or a box body for trucks that the optional are separable from the carrier vehicle and can be placed on supports.

Es sind bereits sogenannte Wechselsysteme bekannt geworden, bei denen es sich um von einem Trägerfahrzeug trennbare und wahlweise auf ausgeklappten Stützen abstellbare Kastenaufbauten handelt. Die Stützen sind dabei um unterseitig an der Plattform angeordnete Anlenkachsen zwischen einer die Plattform tragenden vertikalen Stützposition und einer unterseitig an die Plattform angeklappten Lage verschwenkbar angelenkt.So-called change systems have already become known in which it is separable from a carrier vehicle and optionally unfolded Supports adjustable box bodies. The supports are there around articulation axes arranged on the underside of the platform between a the platform supporting vertical support position and one on the underside the platform folded position hinged.

Siehe als Beispiele die Dokumente WO-A-94/26630 und DE-A-25 05 159.See for example documents WO-A-94/26630 and DE-A-25 05 159.

Die vorbekannten Wechselsysteme haben sich bewährt, erscheinen aber im Hinblick auf ein erleichtertes Ent- und Beladen der Plattform oder des Kastenaufbaus im abgestellten Zustand noch verbesserungsbedürftig.The previously known exchange systems have proven themselves, but appear in the With a view to facilitating loading and unloading of the platform or the box body in the parked state still in need of improvement.

Demgemäß besteht die der Erfindung zugrunde liegende Aufgabe in der Schaffung einer Plattform, bei der es sich um eine sowohl auf einem Trägerfahrzeug aufnehmbare als auch auf Stützen abstellbare Ladeplattform oder einen Kastenaufbau handeln kann, die nach dem Abstellen auf Stützen im Interesse einer verbesserten Zugänglichkeit wahlweise absenkbar ist.Accordingly, the object underlying the invention is Creation of a platform that is both on a carrier vehicle loadable loading platform or storage platform or can act a box structure, which after parking on supports in Interest of improved accessibility can be optionally lowered.

Gelöst ist diese Aufgabe dadurch, daß bei der im Oberbegriff des Patentanspruchs 1 angegebenen Plattform die Stützbeine jeweils längsverschieblich in einem Lagerelement geführt und je mit einem Hubzylinder ausgerüstet sind, das die Lagerelemente mittels unterseitig an der Plattform angeordneter Führungen aus ihren Nichtgebrauchsstellungen, in denen die Stützbeine an die Plattform angeklappt sind, in Positionen seitlich von der Plattform verschiebbar und danach mit den Stützbeinen um Achsen, die sich in Verschieberichtung der Lagerelemente erstrecken, in vertikale Stützpositionen verschwenkbar sowie in den Stützpositionen gegen Verschwenken der Stützbeine in deren Nichtgebrauchsstellungen arretierbar sind, und daß die Plattform über die Lagerelemente mittels der den Stützbeinen zugeordneten Hubzylinder anheb- und absenkbar ist.This object is achieved in that in the preamble of the claim 1 specified platform, the support legs are each longitudinally displaceable guided in a bearing element and each equipped with a lifting cylinder are that the bearing elements arranged on the underside of the platform Guides from their non-use positions, in which the support legs on the platform is folded, can be moved laterally into positions from the platform and then with the support legs around axes that are in the direction of displacement extend the bearing elements, pivotable into vertical support positions as well as in the support positions against pivoting of the support legs can be locked in their non-use positions, and that the platform via the bearing elements by means of the lifting cylinders assigned to the support legs can be raised and lowered.

Besondere Bedeutung kommt einer derartig absenkbaren Plattform bei sogenannten Getränkefahrzeugen zu, indem etwa bei einer Festzeltbelieferung ein Getränkeaufbau zunächst auf den Stützbeinen unter Trennung vom Trägerfahrzeug abgestellt und dann in eine gewünschte Zwischenstellung oder auf den Boden abgesenkt wird, so daß in dem Getränkeaufbau enthaltene Getränke in einfacher Weise von Hand entnommen werden können.Such a lowerable platform is particularly important for so-called Beverage vehicles too, for example when delivering marquees a beverage structure first on the support legs with separation from the carrier vehicle parked and then in a desired intermediate position or is lowered to the floor so that contained in the beverage structure Drinks can be easily removed by hand.

Zwar sind schon Hubsysteme bekannt geworden, mittels deren beispielsweise ein auf einem Trägerfahrzeug aufgenommener Kastenaufbau zunächst angehoben und nach dem Wegfahren des Trägerfahrzeugs abgesenkt werden kann. Dabei handelt es sich aber um von dem Kastenaufbau unabhängige Hubeinrichtungen, die separat mitgeführt oder am jeweiligen Einsatzort vorgehalten werden müssen. Derartige Hubeinrichtungen sind umständlich in der Handhabung und darüber hinaus teuer. Lifting systems have already become known, for example by means of them a box body recorded on a carrier vehicle initially raised and lowered after the carrier vehicle has moved away can. However, these are independent of the box structure Lifting devices that are carried separately or at the respective location must be kept available. Such lifting devices are cumbersome in handling and also expensive.

Bei der Erfindung handelt es sich demgegenüber darum, daß die Mittel zum Absenken und Anheben unmittelbar der Plattform zugeordnet und mithin in jedem Bedarfsfalle an jedem beliebigen Orte verfügbar sind.In contrast, the invention is that the means for Lowering and lifting directly assigned to the platform and therefore in are available at any location, in any need.

Zweckmäßigerweise sind die Lagerelemente mit den in diesen längsverschieblich aufgenommenen Stützbeinen aus deren Nichtgebrauchsstellungen unter der Plattform in über die seitlichen Plattform-Längskanten vorstehende Lagen verschiebbar und darüber hinaus in ihren den Stützpositionen der Stützbeine entsprechenden Einstellungen durch formschlüssig wirkende Verriegelungsmittel arretierbar.The bearing elements are expediently longitudinally displaceable with them recorded support legs from their non-use positions under the platform in protruding beyond the lateral longitudinal edges of the platform Layers are displaceable and also in their supporting positions Support legs corresponding settings by positive locking means lockable.

Dabei hat es sich als besonders zweckmäßig erwiesen, wenn von jedem Lagerelement innenseitig als Verriegelungsmittel wenigstens ein Rastbolzen vorsteht, und die Rastbolzen der Lagerelemente in den den Stützpositionen der Stützbeine entsprechenden Einstellungen der Lagerelemente formschlüssig fest, aber entriegelbar, in jeweils eine Rastausnehmung der Plattform eingreifen.It has proven to be particularly useful if of each bearing element on the inside as locking means at least one locking bolt protrudes, and the locking bolts of the bearing elements in the supporting positions the support legs corresponding settings of the bearing elements firm, but unlockable, each in a recess in the platform intervention.

Ein derartiger Eingriff wird dadurch bewerkstelligt, daß die Lagerelemente mit den in diesen längsverschieblich aufgenommenen Stützbeinen etwas über die der Stützposition der Stützbeine entsprechenden Stellungen unter der Plattform hinaus hervorgezogen und nach dem Verschwenken der Stützbeine in ihre vertikalen Stützlagen wieder etwas eingeschoben werden, derart, daß die innenseitig von den Lagerelementen vorstehenden Rastbolzen in die Rastausnehmungen der Plattform formschlüssig eingreifen und dadurch eine höchst wirksame Sicherung der Lagerelemente gegen ein unerwünschtes Zurückverschwenken der Stützbeine aus deren Stützpositionen verhindern.Such an intervention is accomplished in that the bearing elements with slightly above the support legs, which can be moved longitudinally the positions corresponding to the support position of the support legs under the Platform pulled out and after pivoting the support legs are pushed back into their vertical support positions, that the locking bolts protruding on the inside from the bearing elements into the Interlocking recesses of the platform engage positively and thereby one highly effective securing of the bearing elements against an undesired Prevent the support legs from pivoting back from their support positions.

Bei einer sinnvollen Weiterbildung der Erfindung handelt es sich bei den Führungen, die das Verschieben der Lagerelemente zwischen Stellungen unter der Plattform und Positionen seitlich von dieser ermöglichen, einerseits um an der Plattform unterseitig befestigte Rundrohre und andererseits um in letzteren axialbeweglich und drehbar aufgenommene sowie fest mit den die Stützbeine längsverschieblich aufnehmenden Lagerelementen verbundene Lagerrohre.In a meaningful development of the invention, the guides are the moving of the bearing elements between positions under enable the platform and positions to the side of it, on the one hand Round tubes fastened to the underside of the platform and on the other hand in the latter axially movable and rotatably received and fixed with the Support legs connected longitudinally receiving bearing elements Bearing tubes.

Die Ausbildung der genannten Führungen aus teleskopartig ineinander geschobenen Rohren, die sowohl eine Verschiebbarkeit in Rohrlängsrichtung als auch eine Verdrehbarkeit der Teile gegeneinander ermöglichen, führt zu einem äußerst einfachen und kostengünstigen Aufbau derartiger Führungen.The formation of the guides mentioned telescopically pushed into one another Pipes that are both slidable in the longitudinal direction of the pipe and also enable the parts to be rotated relative to one another leads to an extremely simple and inexpensive construction of such guides.

In gleichfalls besonders einfacher Weise sind die teleskopartig ineinander geführten und gegeneinander verdrehbaren Rohre mittels diese in Lochungen durchdringender Sicherungsbolzen in den jeweiligen Einstellagen gegeneinander arretierbar.In a particularly simple manner, they are telescopically one inside the other guided and rotatable tubes by means of these in perforations penetrating safety bolts against each other in the respective setting positions lockable.

Bei solchen Lagerelementen, von denen innenseitig als Verriegelungsmittel Rastbolzen vorstehen, ist die Anordnung der Lochungen in den Rundrohren und Lagerrohren so getroffen, daß diese Lochungen nur dann deckungsgleich stehen und das Einschieben eines Sicherungsbolzens ermöglichen, wenn die von den Lagerelementen vorstehenden Rastbolzen in die Rastausnehmungen der Plattform eingreifen.In such bearing elements, of which inside as a locking means Projecting locking bolts is the arrangement of the perforations in the round tubes and bearing tubes so that these perforations are only congruent stand and allow the insertion of a safety bolt, if the locking bolts protruding from the bearing elements into the locking recesses intervene on the platform.

Eine abermalige Weiterbildung der Erfindung sieht vor, daß die Stützbeine jeweils aus zwei Stützenhälften bestehen, die an ihren in der Stützposition unteren Enden mit einer Bodenplatte fest verbunden sind, daß zwischen den Stützenhälften jeweils ein doppelt wirkender Hubzylinder aufgenommen und dieser mit einem seiner Wirkelemente mit der Bodenplatte des betreffenden Stützbeins fest verbunden ist, und daß an dem jeweils anderen Wirkelement des jeweiligen Hubzylinders wenigstens ein Mitnehmer angeordnet ist, d beim Anheben und Absenken der Plattform an dem Lagerelement des betreffenden Stützbeins angreift.Another development of the invention provides that the support legs each consist of two support halves that are in their in the support position lower ends are firmly connected to a base plate that between the Support halves each a double-acting lifting cylinder and this with one of its active elements with the base plate of the person concerned Support leg is firmly connected, and that on the other active element of the respective lifting cylinder at least one driver is arranged, d when lifting and lowering the platform on the bearing element of the concerned Support leg attacks.

Bei den Wirkelementen der Hubzylinder handelt es sich um den eigentlichen Zylinder und einen in diesem längsverschieblich geführten Kolben mit einer endseitig über den Zylinder vorstehenden Kolbenstange.The active elements of the lifting cylinders are the actual ones Cylinder and a piston with a longitudinally displaceable piston piston rod protruding from the end of the cylinder.

Bei der zuletzt-genannten Ausgestaltung ist zweckmäßigerweise jeweils eine Kolbenstange des Hubzylinders mit der Bodenplatte des betreffenden Stützbeins verbunden und als Mitnehmer sind am Zylinderteil auf einander gegenüberliegenden Seiten Zapfen angeordnet, die zwischen den Stützenhälften hindurch seitlich über diese vorstehen und beim Anheben und Absenken der Plattform unterseitig an den Lagerelementen angreifen bzw. mit an den Lagerelementen angebrachten Gegenhaltern zusammenwirken.In the last-mentioned embodiment, one is expediently in each case Piston rod of the lifting cylinder with the base plate of the support leg in question connected and as drivers are on the cylinder part on opposite one another Side pegs arranged between the column halves protrude laterally over them and when lifting and lowering the Engage the platform on the underside of the bearing elements or on the bearing elements attached counter hold together.

Bei diesen Gegenhaltem der vorzugsweise in der Art von Führungsrohren ausgebildeten Lagerelemente kann es sich zweckmäßigerweise um zu den Bodenplatten hin offene Ausnehmungen handeln, in welche die als Mitnehmer von dem Zylinderteil des Hubzylinders vorstehenden Zapfen vor dem Anheben oder Absenken der Plattform einrasten.With these counterparts, preferably in the manner of guide tubes trained bearing elements, it can be convenient to the Floor plates act open recesses, in which the act as a driver from the cylinder part of the lifting cylinder protruding pin before Snap the platform up or down.

Eine andere sinnvolle Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Stützbeine jeweils ein Stützenrohr mit vorzugsweise rechteckigem Querschnitt aufweisen, daß innerhalb der Stützenrohre jeweils ein Hubzylinder mit einem mit einer Bodenplatte fest verbundenen Wirkelement und einem in der Stützen Stützposition gesehen - nach oben weisenden weiteren Wirkelement aufgenommen ist und daß wenigstens ein Mitnehmer über mit dem freien Ende des weiteren Wirkelements fest verbundene Zugglieder wirkverbunden ist, welcher Mitnehmer beim Anheben oder Absenken der Ladeplattform das Lagerelement der jeweiligen Stütze untergreift. Another useful embodiment of the invention is characterized in that that the support legs each have a support tube, preferably rectangular Have cross-section that a lifting cylinder within the support tubes with an active element firmly connected to a base plate and one seen in the support position - another pointing upwards Active element is added and that at least one driver over tension members firmly connected to the free end of the further active element is operatively connected, which driver when lifting or lowering the Loading platform engages under the bearing element of the respective support.

Vorzugsweise ist die Anordnung dabei so getroffen, daß ein Zylinderteil des Hubzylinders mit der Bodenplatte fest verbunden ist und eine Kolbenstange des Hubzylinders von dessen Zylinderteil nach oben vorsteht, deren freies Ende über Zugglieder mit dem Mitnehmer wirkverbunden ist.The arrangement is preferably such that a cylinder part of the Lift cylinder is firmly connected to the base plate and a piston rod of the lifting cylinder protrudes from its cylinder part upwards, its free End is operatively connected to the driver via tension members.

Im Gegensatz zu der vorhergehenden Ausgestaltung mit aus zwei Stützenhälften bestehenden Stützbeinen ist für diese Ausgestaltung charakteristisch, daß die Stützbeine geschlossene Stützenrohre aufweisen und in letzteren jeweils ein doppelt wirkender Hubzylinder aufgenommen ist., dessen nach oben weisendes Wirkelement, bei dem es sich vorzugsweise um die Kolbenstange handeln kann, über geeignete Zugglieder mit einem das jeweilige Lagerelement beim Anheben oder Absenken der Ladeplattform untergreifenden Mitnehmer fest verbunden ist. Dies führt zu einer sehr einfachen und kompakt bauenden Ausbildung der Stützbeine.In contrast to the previous embodiment with two support halves existing support legs is characteristic of this configuration, that the support legs have closed support tubes and in the latter each a double-acting lifting cylinder is added top-facing active element, which is preferably the piston rod can act, using suitable tension links with each one Under the bearing element when lifting or lowering the loading platform Driver is firmly connected. This leads to a very simple and compact construction of the support legs.

Dabei hat sich als zweckmäßig erwiesen, als Zugglieder zwei über eine Quertraverse mit dem nach oben weisenden Wirkelement fest verbundene und aufeinander gegenüberliegenden Seiten von der Kolbenstange verlaufende Flacheisen zu verwenden, die sich außenseitig vom jeweiligen Stützenrohr durch Längsführungen des betreffenden Lagerelements hindurcherstrecken und mit dem Mitnehmer des betreffenden Stützbeins fest verbunden sind.It has proven to be expedient, as tension members two over one Crossbar firmly connected to the active element pointing upwards and opposite sides of the piston rod Flat iron to use, which is on the outside of the respective support tube extend through longitudinal guides of the bearing element in question and firmly connected to the driver of the relevant support leg are.

Eine besonders einfache Konstruktion ergibt sich, wenn die mit den Zuggliedem verbundenen Mitnehmer als das jeweilige·Stützenrohr mit Spiel umschließende Rahmen ausgebildet sind.A particularly simple construction results when the with the tension members connected driver as the respective · support tube with play enclosing Frames are formed.

Eine abermalige Weiterbildung sieht vor, daß die mit den freien Enden der Kolbenstangen der jeweiligen Stützbeine fest verbundenen Quertraversen, mit denen jeweils die Zugglieder fest verbunden sind, beidseitig über die Lagerelemente vorstehen und beim Einfahren der Kolbenstangen in ihre zugeordneten Zylinderteile oberseitig auf die Lagerelemente aufsetzende Anschläge bilden. Derartige Anschläge verhindern das Einziehen der Kolbenstangen unter die Oberkanten der das jeweilige Stützbein führenden Lagerelemente.Another development provides that the with the free ends of the Piston rods of the respective support legs of fixed cross members, with which the tension members are firmly connected, on both sides via the bearing elements protrude and when retracting the piston rods into their assigned Cylinder parts on the top of the bearing elements on the bearing elements form. Such stops prevent the piston rods from being drawn in under the upper edges of the bearing elements leading the respective support leg.

Eine gleichfalls sinnvolle Weiterbildung der Erfindung sieht vor, daß die Stützbeine mit den diese aufnehmenden Lagerelementen zumindest in den Stützpositionen fest, jedoch lösbar verriegelbar sind.An equally useful development of the invention provides that the Support legs with the bearing elements receiving them at least in the Support positions are fixed, but can be locked releasably.

Die lösbare Verriegelung der Stützbeine mit den diese aufnehmenden Lagerelementen kann in einfacher Weise mittels letztere und die Stützbeine in Lochungen durchdringender Steckbolzen erfolgen.The releasable locking of the support legs with the bearing elements receiving them can in a simple manner by means of the latter and the support legs Perforated plug bolts.

Zweckmäßigerweise sind die Lochungen für die Aufnahme der Steckbolzen in den Lagerelementen als Langlöcher ausgebildet, die sich in Längsrichtung der Stützbeine erstrecken. Dies führt dazu, daß bei auf den Stützbeinen abgestellter Plattform die in der Stützposition oberen Enden der genannten Langlöcher auf den Steckbolzen aufsitzen und dadurch die Steckbolzen in ihren Verriegelungslagen gesichert sind.The perforations are expedient for receiving the plug pins formed in the bearing elements as elongated holes that extend in the longitudinal direction the support legs extend. This leads to the fact that when parked on the support legs Platform the upper ends of the said in the support position Sit the elongated holes on the socket pins and thereby the socket pins in their locking positions are secured.

Zumindest bei der Ausbildung der Stützbeine mit zwei Stützenhälften ist es von Vorteil, wenn die Verriegelung der Stützbeine mit den Lagerelementen durch zwei Steckbolzen erfolgt, von denen jeweils einer in der Verriegelungslage eine Stützenhälfte durchdringtAt least in the formation of the support legs with two support halves, it is advantageous if the locking of the support legs with the bearing elements done by two socket pins, one of which is in the locked position penetrates one half of the column

Die beiden voneinander beabstandeten Steckbolzen eines Stützbeins sind zweckmäßigerweise über ein Sicherungsblech miteinander verbunden, so daß die Verriegelung der Lagerelemente mit ihren Stützbeinen mittels einer Steckeinheit gelingt.The two spaced-apart pins of a support leg expediently connected to one another via a locking plate, so that the locking of the bearing elements with their support legs by means of a Plug-in unit succeeds.

Im Rahmen der Erfindung können die Lagerelemente aber auch mit speziellen Sicherungsmitteln zum Arretieren der Steckbolzen bei auf den Stützbeinen aufgenommener Plattform ausgerüstet sein, welche Sicherungsmittel formschlüssig wirken und beim Anheben der Plattform außer Eingriff mit den Steckbolzen gelangen, indem im Rahmen der Längserstreckung der Langlöcher in den Lagerelementen letztere gegenüber den Stützbeinen so anhebbar sind, daß die Sicherungsmittel ausrasten.In the context of the invention, the bearing elements can also be used with special Securing means for locking the plug pins when on the support legs platform, which safety devices act positively and when lifting the platform out of engagement with the Insert pins by using the longitudinal extension of the elongated holes in the bearing elements the latter can be raised relative to the support legs are that the securing means disengage.

Zweckmäßigerweise kann es sich bei diesen Sicherungsmitteln um an den Lagerelementen angebrachte Sicherungswinkel handeln, die bei abgestellter Plattform von den Steckbolzen vorstehende Sicherungsbleche übergreifen und beim Anheben im Rahmen der Längserstreckung der die Steckbolzen aufnehmenden Langlöcher der Lagerelemente die Sicherungsbleche freigeben.These securing devices can expediently be the Bearing elements attached securing brackets act when the Grip the locking tabs protruding from the platform and when lifting within the longitudinal extension of the socket pins Release the locking plates in the elongated holes in the bearing elements.

Der in den Fig. 1 bis 4 veranschaulichte Kastenaufbau 10 besitzt eine Ladeplattform 11 mit je zwei im Bereich der seitlichen Plattform-Längskanten 12, 12' unterseitig im Abstand voneinander angeordneten Stützbeinen 13, die in einer Nichtgebrauchsstellung unter die Ladeplattform 11 einschiebbar und unterseitig an diese abklappbar sind. Die linke Hälfte von Fig. 4 zeigt eine auf einem Lastkraftwagen 15 aufgenommene Ladeplattform 11 mit einem in der Nichtgebrauchsstellung befindlichen Stützbein 13.The box structure 10 illustrated in FIGS. 1 to 4 has a loading platform 11 with two each in the area of the lateral platform longitudinal edges 12, 12 'on the underside, spaced apart support legs 13 which in a non-use position can be inserted under the loading platform 11 and can be folded down on the underside. The left half of Fig. 4 shows one a truck 15 loaded loading platform 11 with one in the Support leg 13 not in use position.

In der Stützposition sind die Stützbeine 13 aus ihren Nichtgebrauchsstellungen unter der Ladeplattform 11 seitlich vorgezogen und stehen dann in der aus der rechten Hälfte von Fig. 4 ersichtlichen Weise seitlich von den Plattform-Längskanten 12. Wie die Fig. 1 bis 3 zeigen, ist der Kastenaufbau 10 bzw. die Ladeplattform 11 aus einer der Auflagerhöhe auf einem Lastkraftwagen 15 entsprechenden Stützposition gemäß Fig. 1 über beliebige Zwischenstellungen, von denen eine in Fig. 2 veranschaulicht ist, bis auf den Boden absenkbar, was Fig. 3 veranschaulicht. In the support position, the support legs 13 are out of their non-use positions pulled forward laterally under the loading platform 11 and then stand in the seen from the right half of Fig. 4 laterally from the platform longitudinal edges 12. As shown in FIGS. 1 to 3, the box structure 10 or the loading platform 11 from one of the support heights on a truck 15 corresponding support position according to FIG. 1 via any intermediate positions, one of which is illustrated in FIG. 2, except for the Lowerable floor, which Fig. 3 illustrates.

Die Stützbeine 13, deren Aufbau unten noch näher erläutert wird, sind längsbeweglich in als rechteckige Führungsrohre ausgebildeten Lagerelementen 16 aufgenommen. Von den Lagerelementen 16 steht rechtwinklig zur Längserstreckung der Stützbeine 13 jeweils ein fest mit dem betreffenden Lagerelement 16 verbundenes Lagerrohr 17 vor, das in einem unterseitig an der Ladeplattform 11 fest angeordneten Rundrohr 18 drehbar und axialbeweglich aufgenommen ist. Die Rundrohre 18 und Lagerrohre 17 bilden Teleskopführungen, die in den jeweiligen Einstellagen mittels die Rohre in Lochungen 19 durchdringender Sicherungsbolzen arretierbar und im nicht arretierten Zustand ein Verschieben der Lagerelemente 16 mit den Stützbeinen 13 zwischen der in der linken Hälfte von Fig. 4 gezeigten Nichtgebrauchsstellung und einer Position seitlich von den Plattform-Längskanten 12 sowie in der ausgestellten Lage ein Verschwenken der Lagerelemente 16 mit den Stützbeinen 13 in die in der rechten Hälfte von Fig. 4 gezeigte Stützposition ermöglichen.The support legs 13, the structure of which is explained in more detail below, are longitudinally movable in bearing elements designed as rectangular guide tubes 16 added. Of the bearing elements 16 is perpendicular to Longitudinal extension of the support legs 13 each firmly with the relevant one Bearing element 16 connected bearing tube 17 in front in a the loading platform 11 fixed tubular 18 rotatable and axially movable is included. The round tubes 18 and bearing tubes 17 form telescopic guides, in the respective setting positions by means of the pipes in perforations 19 penetrating safety bolts can be locked and not locked Condition a displacement of the bearing elements 16 with the support legs 13 between the non-use position shown in the left half of FIG. 4 and a position to the side of the platform longitudinal edges 12 as well in the position shown a pivoting of the bearing elements 16 with the Support legs 13 in the support position shown in the right half of FIG. 4 enable.

Auf der zur Plattform hinweisenden Seite sind an den Lagerelementen 16 vorstehende Rastbolzen 20 angebracht, die in der aus der rechten Hälfte von Fig. 4 ersichtlichen Stützposition in seitliche Rastausnehmungen 21 an der Ladeplattform 11 formschlüssig eingreifen. Die von diesen Rastbolzen 20 in der Eingriffslage in die Rastausnehmungen 21 der Ladeplattform 11 vermittelte Verdrehsicherung wird dadurch erreicht, daß die Lagerelemente 16 mit den Stützbeinen 13 um ein der Eingriffslänge der Rastbolzen 20 entsprechendes Maß über die Stützpositionen aus den Nichtgebrauchsstellungen herausgezogen, dann in die aus der rechten Hälfte von Fig. 4 ersichtliche Stützposition verschwenkt und anschließend bis zum formschlüssig festen Eingriff der Rastbolzen 20 in die genannten Rastausnehmungen 21 an die Ladeplattform 11 herangeschoben werden. On the side pointing towards the platform, the bearing elements 16 protruding locking pin 20 attached in the from the right half of Fig. 4 apparent support position in lateral recesses 21 on the Intervene in loading platform 11 in a form-fitting manner. The of these locking bolts 20 in the engagement position in the locking recesses 21 of the loading platform 11 Protection against rotation is achieved in that the bearing elements 16 with the support legs 13 by a corresponding to the engagement length of the locking pin 20 Measure of the support positions from the non-use positions pulled out, then into that shown in the right half of Fig. 4 Support position swiveled and then until it is positively fixed Engagement of the locking pin 20 in the said recesses 21 to the Loading platform 11 are pushed up.

Die fest mit den in den Rundrohren 18 längsverschiebbar und drehbar aufgenommenen Lagerrohren 17 verbundenen Lagerelemente 16 sind als Führungsrohre mit rechteckigem Querschnitt ausgebildet. Die Stützbeine 13 umfassen jeweils zwei U-förmige Stützenhälften 23, 23', die an ihren in der Stützposition unteren Enden jeweils fest mit einer Bodenplatte 24 verbunden sind. Die jeweils von einem Steg vorstehenden Schenkel der Stützenhälften 23, 23' sind aufeinander zugerichtet und verlauten unter Ausbildung eines Längsschlitzes beabstandet voneinander. Innerhalb der U-förmigen Stützenhälften 23, 23' eines jeden Stützbeins 13 ist ein doppelt wirkender Hubzylinder 25 mit einem Zylinderteil 26 und einer an der Bodenplatte 24 befestigten Kolbenstange 27 aufgenommen, die ihrerseits mit einem im Zylinderteil axialbeweglich geführten Kolben fest verbunden ist. Mit den U-förmigen Stützenhälften 23, 23' und der Bodenplatte 24 sind zwei voneinander beabstandete Laschen 28, 28' fest verbunden, die zwischen sich das Ende der Kolbenstange 26 aufnehmen. Verbunden ist die Kolbenstange mit diesen Laschen 28, 28' mittels einer sich durch Lochungen in den Laschen und der Kolbenstange hindurcherstreckenden Schraube 29.The fixed with the longitudinally displaceable and rotatably received in the round tubes 18 Bearing tubes 17 connected bearing elements 16 are as guide tubes formed with a rectangular cross section. The support legs 13 each comprise two U-shaped support halves 23, 23 ', which at their in the Support position lower ends each firmly connected to a bottom plate 24 are. The legs of the support halves projecting from a web 23, 23 'are directed towards one another and announce to form one Longitudinal slot spaced apart. Inside the U-shaped column halves 23, 23 'of each support leg 13 is a double-acting lifting cylinder 25 with a cylinder part 26 and one attached to the base plate 24 Piston rod 27 added, which in turn with a in the cylinder part axially movable piston is firmly connected. With the U-shaped support halves 23, 23 'and the base plate 24 are two spaced apart Tabs 28, 28 'fixedly connected between themselves the end of the piston rod Record 26. The piston rod is connected to these tabs 28, 28 'by means of a through holes in the tabs and the Screw 29 extending through the piston rod.

An dem zur Bodenplatte 24 hinweisenden Ende des Zylinderteils 26 sind auf gegenüberliegenden Seiten zwei durch die Schlitze zwischen den beiden Stützenhälften 23, 23' vorstehende Zapfen 30, 30' fest angeordnet, die beim Anheben und Absenken der Ladeplattform 11 die Lagerelemente 16 auf einander gegenüberliegenden Seiten untergreifen. Um ein sicheres Zusammenwirken der von dem Zylinderteil 26 auf einander gegenüberliegenden Seiten vorstehenden Zapfen 30, 30' mit den Lagerelementen 16 zu gewährleisten, sind die Lagerelemente 16 ebenfalls auf einander gegenüberliegenden Seiten mit zu den Bodenplatten 24 der Stützbeine 13 hin offenen Ausnehmungen 31 ausgerüstet, in welche die vom jeweiligen Zylinderteil 26 vorstehenden Zapfen 30 beim Anheben und Absenken der Ladeplattform 11 einrasten.At the end of the cylinder part 26 pointing towards the base plate 24 are on opposite sides two through the slots between the two Support halves 23, 23 'projecting pins 30, 30' fixedly arranged at Raising and lowering the loading platform 11, the bearing elements 16 on each other reach under on opposite sides. To work together safely that of the cylinder part 26 on opposite one another To ensure the projecting pin 30, 30 'with the bearing elements 16, are the bearing elements 16 also on opposite sides Sides with recesses open towards the base plates 24 of the support legs 13 31 equipped, in which the protruding from the respective cylinder part 26 Pin 30 when lifting and lowering the loading platform 11 engage.

Bei auf den Stützbeinen 13 abgestellter Ladeplattform 11 sind die in Stützposition stehenden Lagerelemente 16 und die zugehörigen Stützbeine 13 formschlüssig fest mittels Steckbolzen 32, 32' verriegelt, die in Lochungen der Lagerelemente 16 und der Stützenhälften 23, 23' aufgenommen sind. Die Lochungen in den Wandungen der Lagerelemente 16 sind als in Richtung der Längserstreckung der Stützbeine 13 verlaufende Langlöcher 33 ausgebildet und die beiden voneinander beabstandeten Steckbolzen zur Sicherung der Stützenhälften 23, 23' eines Stützbeins 13 gegenüber dem zugeordneten Lagerelement 16 sind jeweils mittels eines Sicherungsblechs 34 zu einer Steckeinheit zusammengefaßt. Die Sicherungsbleche 34 stehen in der Stützposition oberseitig über die Steckbolzen 32, 32' vor und sind bei abgestellter Ladeplattform 11 oberseitig von an dem jeweiligen Lagerelement 16 angeordneten Sicherungswinkeln 35, 35' übergriffen.When the loading platform 11 is parked on the support legs 13, they are in the support position standing bearing elements 16 and the associated support legs 13 positively firmly locked by means of locking pins 32, 32 ', which are in the holes of Bearing elements 16 and the support halves 23, 23 'are added. The Perforations in the walls of the bearing elements 16 are as in the direction the elongated holes 33 extending the longitudinal extension of the support legs 13 are formed and the two spaced socket bolts for securing the support halves 23, 23 'of a support leg 13 opposite the associated one Bearing element 16 are each one by means of a locking plate 34 Plug unit summarized. The locking plates 34 are in the Support position on the upper side via the plug pins 32, 32 'and are in the parked position Loading platform 11 on top of the respective bearing element 16 arranged securing angles 35, 35 'overlapped.

Wenn eine auf einem Lastkraftwagen 15 aufgenommene Ladeplattform 11 auf Stützen 13 abgestellt werden soll, müssen zunächst die Sicherungsbolzen aus dem die Rundrohre 18 und die Lagerrohre 17 durchdringenden Lochungen 19 herangezogen und dadurch die Verriegelungen der Lagerrohre 17 mit den unterseitig an der Ladeplattform angebrachten Rundrohren 18 aufgehoben werden. Danach sind die Lagerelemente 16 mit den unterseitig an die Ladeplattform 11 angeklappten Stützbeinen 13 unter Ladeplattform 11 in Lagen seitlich von dieser herausziehbar und dann um die von den Lagerrohren 17 gebildeten Achsen so zu verschwenken, daß die Stützbeine 13 mit nach unten weisenden Bodenplatten 24 sich in Vertikallagen erstrecken. Danach müssen die Lagerelemente 16 mit den Stützbeinen 13 so an die Ladeplattform herangeschoben werden, daß die innenseitig von den Lagerelementen 16 vorstehenden Rastbolzen 20 in die seitlichen Rastausnehmungen 21 der Ladeplattform 11 eingreifen. Danach müssen die Lagerrohre 17 erneut mit den Rundrohren durch Einschieben der Sicherungsbolzen in die Lochungen 19 verriegelt werden. Letzteres gelingt nur, wenn die Rastbolzen 20 formschlüssig in die seitlichen Rastausnehmungen 21 an der Ladeplattform eingreifen.When a loading platform 11 accommodated on a truck 15 to be placed on supports 13, the safety bolts must first from the perforations penetrating the round tubes 18 and the bearing tubes 17 19 and thus the locking of the bearing tubes 17 with the round tubes 18 attached to the underside of the loading platform To get picked up. Thereafter, the bearing elements 16 with the underside support legs 13 folded under the loading platform 11 to the loading platform 11 can be pulled out in layers to the side of this and then around that of the bearing tubes 17 formed axes to pivot so that the support legs 13 with downward facing floor panels 24 extend in vertical positions. After that so the bearing elements 16 with the support legs 13 to the loading platform are pushed in that the inside of the bearing elements 16 protruding locking bolts 20 in the lateral locking recesses 21 of the loading platform 11 engage. After that, the bearing tubes 17 must again with the round tubes by inserting the safety bolts into the perforations 19 can be locked. The latter only works if the locking bolts 20 positively in the lateral recesses 21 on the loading platform intervention.

Nach diesen Vorbereitungen wird das Trägerfahrzeug 15 mittels seiner Luftfederung abgesenkt und unter der Ladeplattform 11 herausgefahren. Infolge der Beaufschlagung der doppelt wirkenden Hubzylinder 25 mit Hydraulikmittel fahren die Zylinderteile 26 aus der in der rechten Hälfte von Fig. 4 ersichtlichen Stellung in die in Fig. 5 gezeigte Lage hoch, wobei die an den unteren Enden der Zylinderteile 26 von diesen seitlich vorstehenden Zapfen 30, 30' in die unterseitig offenen Ausnehmungen 31 der Lagerelemente 16 eingreifen.After these preparations, the carrier vehicle 15 by means of its Air suspension lowered and extended under the loading platform 11. As a result the application of hydraulic medium to the double-acting lifting cylinders 25 drive the cylinder parts 26 from the right half of FIG. 4th apparent position in the position shown in Fig. 5 high, the at the lower ends of the cylinder parts 26 of these laterally projecting pins 30, 30 'into the recesses 31 of the bearing elements 16 which are open on the underside intervention.

Beim Anheben werden die beim Abstellen der Lagerplattform 11 auf Stützen auf den Steckbolzen 32, 32', die sich durch die Langlöcher 33, 33' in den Lagerelementen 16 und durch Lochungen in den Stützenhälften 23, 23' hindurcherstrecken, aufliegenden Lagerelemente 16 und damit die Ladeplattform 11 im Rahmen der Längserstreckung der genannten Langlöcher 33, 33' angehoben. Dadurch gelangen die an den Lagerelementen angebrachten Sicherungswinkel 35, 35' außer Eingriff mit Sicherungsblechen 34, die jeweils zwei Steckbolzen 32, 32' zu einer Steckeinheit verbinden. Danach sind die Steckbolzen 32, 32' aus ihren Sicherungspositionen herausziehbar und die Ladeplattform 11 ist aus der in Fig. 5 ersichtlichen Stützposition in eine beliebige Zwischenstellung oder bis auf den Boden absenkbar, was Fig. 6 zeigt.When lifting the when the storage platform 11 is turned off Support on the plug pins 32, 32 ', which extend through the elongated holes 33, 33' in the bearing elements 16 and through perforations in the support halves 23, 23 ' extend through, resting bearing elements 16 and thus the loading platform 11 as part of the longitudinal extension of the elongated holes 33 mentioned, 33 'raised. This will get the attached to the bearing elements Locking bracket 35, 35 'out of engagement with locking washers 34, each Connect two socket pins 32, 32 'to form a plug-in unit. After that are the socket pins 32, 32 'can be pulled out of their securing positions and the loading platform 11 is from the support position shown in FIG. 5 in a any intermediate position or can be lowered to the floor, as shown in FIG. 6 shows.

Wenn die Ladeplattform 11 wieder angehoben werden soll, etwa um auf einem Lastkraftwagen 15 aufgenommen zu werden, geschieht dies in sinngemäß umgekehrter Reihenfolge wie beim Absenken. Mit den oberen Enden der Stützenhälften 23, 23' fest verbundene und seitlich über diese vorstehende Bleche 36, 36' bilden Anschläge zur Begrenzung der Bewegbarkeit der Stützbeine 13 gegenüber den diese aufnehmenden Lagerelementen 16.If the loading platform 11 is to be raised again, for example on a Trucks 15 to be included, this is done in analogy reverse order of lowering. With the top ends of the support halves 23, 23 'firmly connected and projecting laterally beyond them Sheets 36, 36 'form stops to limit the mobility the support legs 13 relative to the bearing elements 16 receiving them.

Die von den Blechen 36, 36' gebildeten Anschläge sind so ausgelegt, daß beim Ausfahren des Zylinderteils 26 gegen die Anschläge sichergestellt ist, daß die Sicherungsbleche 34 außer Eingriff mit den Sicherungswinkeln 35 sind. Gleichzeitig ist sichergestellt, daß nicht die volle Länge der Langlöcher 33, 33' ausgenützt wird, um zu verhindern, daß die Steckbolzen 32, 32' in den unteren Rundungen der Langlöcher anliegen und verklemmen. Dies bedeutet, daß der Abstand der Oberkante der Lagerelemente 16 bis zur Unterkante der die Anschläge bildenden Bleche 36, 36' immer um ein vorbestimmtes Maß kleiner ist als die Längserstreckung der Langlöcher 33, 33'.The stops formed by the sheets 36, 36 'are designed so that when extending the cylinder part 26 against the stops is ensured, that the locking washers 34 out of engagement with the locking brackets 35 are. At the same time, it is ensured that the full length of the elongated holes is not 33, 33 'is used to prevent the plug pins 32, 32' in fit and jam the lower curves of the elongated holes. This means, that the distance between the upper edge of the bearing elements 16 to the lower edge of the metal sheets 36, 36 'forming the stops is always a predetermined one Dimension is smaller than the longitudinal extent of the elongated holes 33, 33 '.

Die in den Fig. 9 bis 14 veranschaulichte Anführungsform unterscheidet sich von der Ausführungsform nach den Fig. 1 bis 8 im wesentlichen nur durch die Ausbildung der Stützbeine. In diesen Figuren sind für gleiche Teile wie in den Fig. 1 bis 8 dieselben Bezugszeichen verwendet, jedoch für abweichende Teile um 100 erhöhte Bezugszeichen. The embodiment illustrated in FIGS. 9 to 14 differs from the embodiment according to FIGS. 1 to 8 essentially only by the formation of the support legs. In these figures, parts are the same as in 1 to 8 uses the same reference numerals, but for different ones Share 100 increased reference numerals.

Bei dieser Ausführungsform sind die fest mit den in den Rundrohren 18 längsverschiebbar und drehbar aufgenommenen Lagerrohren 17 verbundenen Lagerelemente 116 als rechteckige Querschnitte aufweisende Führungsrohre ausgebildet, in denen die ebenfalls rechteckigen Querschnitt aufweisenden Stützenrohre 123 der Stützbeine 113 längsbeweglich geführt sind. An ihrem in der Stützposition unteren Enden sind die Stützenrohre 123 jeweils mit einer Bodenplatte 124 fest verbunden. Innerhalb der Stützenrohre 123 ist jeweils ein doppelt wirkender Hubzylinder 125 mit an der Bodenplatte 124 befestigtem Zylinderteil 126 und einer- in der Stützposition - nach oben weisenden Kolbenstange 127 aufgenommen, die ihrerseits mit einem im Zylinderteil 126 des Hubzylinders 125 axialbeweglich geführten Kolben fest verbunden ist. Die freien Enden der Kolbenstangen 127 sind jeweils mit einer Quertraverse 128 mittels eines Zapfens 129 fest verbunden.
