Definitions
- the invention relates to an expandable container, e.g. According to the ISO standard, in particular as a work space, according to the preamble of claim 1.
- Such walk-in containers are also referred to as Shelter in Anglo-American language area.
- An expandable container is eg from the DE-G 92 16 314.9 known. It comprises a base container with hinged side walls and one or more extendable from the base container expansion elements.
- An extension element comprises two side walls and a front wall. In the state with extended extension element form two unfolded side walls of the base container roof wall and bottom wall of an extension element.
- a disadvantage of this design the large sealing lengths that are necessary for the sealing of the container along the roof and bottom wall. This is particularly problematic in the demand for ABC-tightness.
- Another expandable container is from the EP 0 682 156 B1 known. It comprises a base container and, to expand the interior, one or more extension elements which can be extended from the base container.
- the extension elements are box-shaped and - with the exception of the open side to the base container - closed on all sides.
- To achieve a flat bottom within the entire container also has a lifting device with which the extension elements are lowered so that after lowering the bottom walls of base container and extension element are at the same height.
- the dimensions must be the two extension elements are chosen so that the one extension element can be retracted into the other extension element.
- a generic expandable container which has a lifting device to achieve a flat bottom, with which the extension elements are lowered so that after lowering the bottom walls of base container and extension element are at the same height.
- the extension elements are open at the top.
- On the base container a foldable about a horizontal axis side wall is present, which forms the roof wall of an extension element when the extension element is extended. With this construction, an improved standing height can be achieved in an extension element.
- a mechanism already present on the container (a side wall of the base container is pivotable about a horizontal axis so that it can also serve as a roof wall of an extension element in the folded-up state) is used to lower the extension elements, so that a uniform one throughout the container Ground level arises.
- a lifting device in particular designed as a linear actuator, is provided, which acts on the hinged side wall. This linear actuator can be supported on both the base container and on the ground on which the container is located.
- a compensation device is provided. This allows a parallel lowering, ie without tilting the extension element from the vertical; the bottom of the extension element remains in a horizontal position during lowering.
- an extension element has at its inner end (ie the end which, when the extension element is extended, comes to rest adjacent to the loading container) a plurality of upper and several lower sliding or unrolling elements, e.g. Roll, up.
- the base container has a plurality of guide elements associated with the upper sliding or unrolling elements, with ramps sloping down towards the extended extension element.
- the base container has a plurality of lower stops associated with lower sliding or unrolling elements, e.g. in the form of vertical profile strips, on.
- extension element When the extension element is fully extended, it assumes a statically fixed, stable position in which the lower sliding or unrolling elements abut against the associated lower stops and the upper sliding or unrolling elements rest on the ramps of the guide elements. This stable position forms the starting position for the lowering of the extension element by actuation of the lifting device.
- Fig. 1 a) to e) show the individual steps in the construction of an expandable container according to the invention with two extension elements 10,20.
- the box-shaped base container 1 contains the two extension elements 10, 20 (see Fig. 1d )).
- the extension element 20 is retracted into the somewhat larger extension element 10 in terms of length and height. It can be seen in each case bottom wall 15,25 and front wall 16,26 of the two extension elements 10,20 and a side wall 27 of the inner extension member 20.
- the base container 1 has bottom wall 2, roof wall 3 and two hinged side walls 4,5, each about a horizontal Axis 41,51 are rotatably mounted on the upper edge of a container wall.
- Fig. 1 b are the two hinged side walls 4,5 folded upwards and are now essentially in a horizontal plane.
- Side surface of the base container 1 and unfolded side wall 4.8 form a right angle.
- variable-length support 55 linear actuator
- the support 55 may e.g. be designed as a telescopic lifting cylinder (for example, hydraulic, pneumatic, electromechanical).
- the smaller extension element 20 is already fully extended. This is done by means arranged on the extension element 20 rollers 23,24 ( Fig. 3 ) in the upper region of the side wall of an extension element. These rollers engage in guideways 80 (see also Fig. 2 ), which are provided on the folded-up side wall 5. For each extension element are advantageously two Guideways provided.
- an extension element 10, 20 in the bottom area has further rollers 21, which roll on extension on the bottom wall 15 of the larger extension element 10.
- the folded-up side wall 5 of the base container 1 now forms the roof wall of the extension element 20.
- the folded-up side wall 4 or 5 is therefore referred to below depending on the context as a roof wall.
- the larger extension element 10 is also completely extended over the guideways 80 arranged on the folded-up side wall 4.
- the extension of the two extension elements was in each case in the horizontal direction, i. without change in the vertical.
- the floor levels of the extension member 10,20 and the base container 1 are respectively different, with the floor level of the base container 1 being lowest and the floor level of the small extension member 20 being the highest.
- the level difference of the smaller extension element to the base container is about 100 mm, the difference in level of the larger extension element 10 to the base container 1 about 50 mm.
- Fig. 1 e shows the fully unfolded container with lowered extension elements 4,5, so that now a uniform floor level is produced within the entire extended container.
- the length of the respective extension element associated support 55 ( Fig. 1 d) reduced.
- the roof walls 4, 5 which are rotatably mounted on the horizontal axis 41, 51 are pivoted out of their horizontal position.
- this compensating device conveys to the outer end of an extension element a preferably equal vertical change in position of the inner end adjacent to the base container 1 Expansion element.
- a significant advantage of this embodiment is that only the relevant lifting device 55 must be actuated for lowering.
- the mechanism for achieving the parallel lowering is coupled with the movement of the lifting device 55 and thus takes place automatically without further external intervention for control.
- Fig. 2 shows a vertical section through a container according to the invention. It can be seen the base container 1, in which an extension element 20 is fully retracted.
- the hinged side wall 5 of the base container 1 is folded from its vertical position of the transport state up into a horizontal position.
- the fulcrum is designated 51.
- a guide track 80 can be seen. It is divided into two parts, wherein the two sections 80a, 80b are connected by means of a hinge 85.
- this hinge 85 By means of this hinge 85, the inner (adjacent to the base container 1) section 80a can be folded down.
- the outside (toward the outer edge of the unfolded container) lying portion 80 b is rigidly connected to the side wall 5.
- the extension element 20 has at the upper edge of its side wall on a roller 23 which engages upon extension into the guide track 80. In Fig. 2 it is located in its starting position, before the extension element 20 is extended. At the outer end of the guideway, the end position of the roller is shown in dashed lines with fully extended extension element 20. Another roller 24 is located at the same height at the rear, in Fig. 2 not shown end of the extension element (see Fig. 3 ).
- the extension element 20 also has bottom rollers 21, which roll on extension on the bottom wall 15 of the larger extension element 10.
- variable-length support 55 Approximately in the middle of the unfolded side wall 5 engages the variable-length support 55, which is supported with its other end to the base container 1.
- the balancing device intended to prevent tilting of the extension element on lowering by the lifting device 55 comprises as an essential element a cable 57, e.g. from steel. It is connected at one end to the outer end of the guide track 80 (alternatively: the side wall 5). The rope 57 is guided over a deflection roller U1 in the lower region of the base container 1. From there it is guided via a further deflection roller U2 in the upper region of the base container 1 (above the pivot point 51) and fastened to the foldable section 80a of the guideway 80 (attachment point B2).
- a cable 57 e.g. from steel. It is connected at one end to the outer end of the guide track 80 (alternatively: the side wall 5).
- the rope 57 is guided over a deflection roller U1 in the lower region of the base container 1. From there it is guided via a further deflection roller U2 in the upper region of the base container 1 (above the pivot point 51) and fastened to the foldable section 80a of
- the length of the rope is adjusted so that when folded side wall 5 according to Fig. 2 the foldable portion 80a of the guide track 80 is oriented horizontally, so that there is no kink on the hinge 85.
- the rope is acted upon by means of a clamping device with a bias voltage.
- the extension element 20 can now via the rollers 23 and 24 ( Fig. 3 ), which roll on the guideways 80, are extended.
- the two rollers 23,24 come to rest in the region of the beginning or end of the guideway 80.
- a roller 23 thus comes to lie on the rigidly connected to the folded-up side wall 5 section 80b, while the other roller 24 comes to lie on the hinged portion 80a of the guideway.
- the lifting device is actuated, ie the length of the support 55 is reduced.
- the side wall 5 together with the outer side of the extension member 20 pivots about the fulcrum 51 downward.
- a corresponding pitch is released at the other end of the rope.
- the foldable portion 80a of the guide rail 80 in which the one guide roller 24 of the extension member 20 engages, is also lowered down together with the inside end of the extension member 20.
- Fig. 3 shows the container in the state with extended and lowered extension element 20th
- the direction of movement of the extension element 20 is substantially vertical.
- the horizontal movement of the extension member 20 due to the fact that the outer end of the pivotable roof 5 moves in a circular path about the pivot point 51, can be neglected, given the radius of the pivoting movement (width of the extension element 10,20 in ISO containers : several meters) and a typically desired amount of lowering of about 100 mm into consideration.
- the described lowering movement is completely reversible.
- the mechanism described is run through in reverse time sequence.
- To lift the lifting device 55 is actuated (change in length of the support).
- the roof wall 5 pivots about the axis 51 upwards.
- the resulting change in position of the attachment point B1 of the rope 57 at the outer end of the roof wall 5 causes the foldable portion 80a of the guideway 80, and thus the inside of the extension member 20 is raised, so that a parallel lifting results without tilting from the vertical.
- the foldable portion 80a of the guide track 80 rests against the roof wall 5.
- the extension element 20 can now be inserted into the base container 1.

- tension struts 101 can be attached.
- the tension struts can be designed in a particularly advantageous embodiment as ropes, which are permanently attached (both with retracted and extended extension element as well as in the transition phase) at the diagonally opposite attachment points between an extension element 10,20 and the base container 1.
- these ropes 55 set the maximum horizontal extension travel of an extension element 10, 20. They also ensure correct alignment of the extension element (no tilting of the extension element from the vertical) with the extension element fully lowered.
- the Fig. 5 to 8 show a second embodiment of the container according to the invention. Unlike in the Fig. 2 to 4 In this case, for the lowering of the inner end of an extension element no cable 57 Fig. 2 . 3 ) or other balancing device needed.

Es ist Aufgabe der Erfindung, einen erweiterbaren Container zu schaffen, der einerseits eine ausreichende Stehhöhe auch in den Erweiterungselementen aufweist und andererseits eine einfach zu bedienende, mechanisch robuste Hubvorrichtung aufweist.It is an object of the invention to provide an expandable container, on the one hand has a sufficient headroom in the extension elements and on the other hand has an easy-to-use, mechanically robust lifting device.
Diese Aufgabe wird mit dem Gegenstand des Patentanspruch 1 gelöst. Vorteilhafte Ausführungen des erfindungsgemäßen Containers sind Gegenstand von Unteransprüchen.This object is achieved with the subject of
Gemäß der Erfindung wird ein am Container bereits vorhandener Mechanismus (eine Seitenwand des Basiscontainers ist um eine horizontale Achse schwenkbar, so dass sie im hochgeklappten Zustand auch als Dachwand eines Erweiterungselements dienen kann) ausgenutzt, um die Erweiterungselemente abzusenken, so dass im gesamten Container ein einheitliches Bodenniveau entsteht. Dazu ist eine Hubvorrichtung, insbesondere ausgebildet als linearer Aktuator, vorgesehen, der auf die klappbare Seitenwand wirkt. Dieser lineare Aktuator kann sich sowohl auf den Basiscontainer als auch auf den Untergrund abstützen, auf dem sich der Container befindet.According to the invention, a mechanism already present on the container (a side wall of the base container is pivotable about a horizontal axis so that it can also serve as a roof wall of an extension element in the folded-up state) is used to lower the extension elements, so that a uniform one throughout the container Ground level arises. For this purpose, a lifting device, in particular designed as a linear actuator, is provided, which acts on the hinged side wall. This linear actuator can be supported on both the base container and on the ground on which the container is located.
Um bei der durch die Hubvorrichtung erzeugten Schwenkbewegung der Seitenwand ein Verkippen des Erweiterungselements zu verhindern, ist in einer bevorzugten Ausführung der Erfindung eine Ausgleichseinrichtung vorhanden. Diese ermöglicht ein paralleles Absenken, d.h. ohne Verkippen des Erweiterungselements aus der Vertikalen; der Boden des Erweiterungselements bleibt während des Absenkens in einer horizontalen Lage.In order to prevent tilting of the extension element in the pivoting movement of the side wall generated by the lifting device, in a preferred embodiment of the invention, a compensation device is provided. This allows a parallel lowering, ie without tilting the extension element from the vertical; the bottom of the extension element remains in a horizontal position during lowering.
In einer weiteren Ausführung weist ein Erweiterungselement an seinem innen liegenden Ende (also dem Ende, das bei ausgezogenem Erweiterungselement benachbart zum Baiscontainer zu liegen kommt) mehrer obere und mehrere untere gleit- oder abrollbare Elemente, z.B. Rollen, auf. Des weiteren weist der Basiscontainer an seinem dem betreffenden Erweiterungselement benachbarten Ende (bei ausgefahrenem Erweiterungselement) mehrere, den oberen gleit- oder abrollbaren Elementen zugeordnete Führungselemente mit zum ausgefahrenen Erweiterungselement hin abfallenden Rampen auf. Außerdem weist der Basiscontainer an seinem dem Erweiterungselement benachbarten Ende (bei ausgefahrenem Erweiterungselement) mehrere, den unteren gleit- oder abrollbaren Elementen zugeordnete untere Anschläge, z.B. in Form vertikal verlaufender Profilleisten, auf. Wird das Erweiterungselement vollständig ausgefahren, so nimmt es eine statisch festgelegte, stabile Position ein, bei der die unteren gleit- oder abrollbaren Elemente an den zugeordneten unteren Anschlägen anschlagen und die oberen gleit- oder abrollbare Elemente auf den Rampen der Führungselemente aufliegen. Diese stabile Lage bildet die Ausgangsposition für das Absenken des Erweiterungselements durch Betätigung der Hubvorrichtung.In a further embodiment, an extension element has at its inner end (ie the end which, when the extension element is extended, comes to rest adjacent to the loading container) a plurality of upper and several lower sliding or unrolling elements, e.g. Roll, up. Furthermore, at its end adjacent to the relevant extension element (when the extension element is extended), the base container has a plurality of guide elements associated with the upper sliding or unrolling elements, with ramps sloping down towards the extended extension element. In addition, at its end adjacent to the extension element (with the extension element extended), the base container has a plurality of lower stops associated with lower sliding or unrolling elements, e.g. in the form of vertical profile strips, on. When the extension element is fully extended, it assumes a statically fixed, stable position in which the lower sliding or unrolling elements abut against the associated lower stops and the upper sliding or unrolling elements rest on the ramps of the guide elements. This stable position forms the starting position for the lowering of the extension element by actuation of the lifting device.

Das Erweiterungselement 20 weist darüber hinaus Bodenrollen 21 auf, die beim Ausfahren auf der Bodenwand 15 des größeren Erweiterungselements 10 abrollen.The
Etwa in der Mitte der aufgeklappten Seitenwand 5 greift die längenveränderliche Stütze 55 an, die sich mit ihrem anderen Ende an dem Basiscontainer 1 abstützt.Approximately in the middle of the unfolded
Die Ausgleichseinrichtung, die das Verkippen des Erweiterungselements beim Absenken durch die Hubvorrichtung 55 verhindern soll, umfasst als wesentliches Element ein Seil 57, z.B. aus Stahl. Es ist mit einem Ende mit dem äußeren Ende der Führungsbahn 80 (alternativ: der Seitenwand 5) verbunden. Das Seil 57 wird über eine Umlenkrolle U1 im unteren Bereich des Basiscontainers 1 geführt. Von dort wird es über eine weitere Umlenkrolle U2 im oberen Bereich des Basiscontainers 1 (oberhalb des Drehpunkts 51) geführt und am klappbaren Abschnitt 80a der Führungsbahn 80 befestigt (Befestigungspunkt B2).The balancing device intended to prevent tilting of the extension element on lowering by the lifting
Die Länge des Seils wird so eingestellt, dass bei hochgeklappter Seitenwand 5 gemäß
Das Erweiterungselement 20 kann nun über die Rollen 23 und 24 (
Zum Absenken des Erweiterungselements 20 wird die Hubvorrichtung betätigt, d.h. die Länge der Stütze 55 vermindert. Die Seitenwand 5 zusammen mit der außen liegenden Seite des Erweiterungselements 20 schwenkt um den Drehpunkt 51 nach unten. Durch die daraus resultierende Abstandsänderung des Befestigungspunkts B1 des Seils 57 zu der unteren Umlenkrolle U1 wird am anderen Seilende eine entsprechende Seillänge freigegeben. Dies führt dazu, dass der klappbare Abschnitt 80a der Führungsschiene 80, in der die eine Führungsrolle 24 des Erweiterungselements 20 eingreift, zusammen mit dem innen liegenden Ende des Erweiterungselements 20 ebenfalls nach unten abgesenkt wird.
Durch Anpassung, insbesondere
- der Position der unteren Umlenkrolle U1 zum äußeren Befestigungspunkt B1 des
Seils 57, - der Position des Befestigungspunkts B2 des Seiles 57 an
dem klappbaren Abschnitt 80a der Führungsbahn, - der Position des
Scharniers 85 für dieTeilung der Führungsbahn 80,
- the position of the lower guide roller U1 to the outer attachment point B1 of the
cable 57, - the position of the attachment point B2 of the
rope 57 at thefoldable portion 80a of the guideway, - the position of the
hinge 85 for the division of theguideway 80,
Die Bewegungsrichtung des Erweiterungselements 20 ist dabei im wesentlichen vertikal. Die Horizontalbewegung, die das Erweiterungselement 20 aufgrund der Tatsache, das sich das äußere Ende des schwenkbaren Dachs 5 auf einer Kreisbahn um den Drehpunkt 51 bewegt, kann vernachlässigt werden, wenn man den Radius der Schwenkbewegung (Breite des Erweiterungselements 10,20 bei ISO-Containern: mehrere Meter) und einem typischerweise angestrebten Betrag des Absenkens von ca. 100 mm in Betracht zieht.The direction of movement of the
Die beschriebene Absenkbewegung ist vollständig reversibel. Beim Anheben des Erweiterungselements 20 wird der beschriebene Mechanismus in zeitlich umgekehrter Folge durchlaufen. Zum Anheben wird die Hubvorrichtung 55 betätigt (Längenänderung der Stütze). Die Dachwand 5 schwenkt um die Achse 51 nach oben. Die resultierende Positionsänderung des Befestigungspunkts B1 des Seils 57 am äußeren Ende der Dachwand 5 führt dazu, dass der klappbare Abschnitt 80a der Führungsbahn 80 und damit die Innenseite des Erweiterungselements 20 angehoben wird, so dass sich ein paralleles Anheben ohne Verkippen aus der Vertikalen ergibt. Wenn die Dachwand 5 eine horizontale Lage erreicht hat, liegt der klappbare Abschnitt 80a der Führungsbahn 80 an der Dachwand 5 an. Das Erweiterungselement 20 kann nun in den Basiscontainer 1 eingeschoben werden.The described lowering movement is completely reversible. When lifting the
Um ein akkurates vertikales und paralleles Absenken in jedem Fall zu gewährleisten, können am Basiscontainer 1 zusätzliche Führungseinrichtungen 99 angebracht sein. Diese können die Form einer vertikal verlaufenden Schiene aufweisen, in die Stifte 98 (
Zur Zugentlastung des Aktuators 55 im ausgefahrenen Zustand der Erweiterungselemente 10,20 können diagonale Zugstreben 101 angebracht werden. Die Zugstreben können in einer besonders vorteilhaften Ausführung als Seile ausgebildet sein, die permanent (sowohl bei eingefahrenem als auch bei ausgefahrenem Erweiterungselement wie auch in der Übergangsphase) an den diagonal gegenüberliegenden Befestigungspunkten zwischen einem Erweiterungselement 10,20 und dem Basiscontainer 1 angebracht sind.For strain relief of the
Beim Ausfahren legen diese Seile 55 den maximalen horizontalen Ausfahrweg eines Erweiterungselements 10,20 fest. Sie stellen außerdem eine korrekte Ausrichtung des Erweiterungselements (kein Verkippung des Erweiterungselements aus der Vertikalen) bei vollständig abgesenktem Erweiterungselement sicher.Upon extension, these

Beim Ausfahren wird das Erweiterungselement 20 in der Führungsbahn 180 an genau einer Stelle (Rolle 123) geführt. An dieser Stelle ist das Erweiterungselement um eine horizontale Achse D drehbar. Diese Rolle 123 ist in einem (in horizontale Richtung sich erstreckenden) Bereich zwischen dem Schwerpunkt S des Erweiterungselements 20 und dem äußeren Ende des Erweiterungselements 20 angeordnet.During extension, the
Das Erweiterungselement 20 weist außerdem an seinem inneren, dem Basiscontainer benachbarten Ende, eine obere 201 und eine untere Rolle 202 auf. Die beiden Rollen sind jeweils über eine Wellenaufnahme 205 (
Der oberen Rolle 201 ist ein Führungselement 211 zugeordnet. Es ist oben am Basiscontainer 1, und zwar an seinem dem Erweiterungselement 20 benachbarten Ende, angeordnet. Es weist die Form eines Winkels mit horizontal sowie vertikal ausgerichteten Schenkeln sowie eine die beiden Schenkel verbindende Rampe auf, die zum Erweiterungselement hin abfällt. Die Rampe weist in einer typischen Ausführung eine Länge (in der Horizontalen) von 10 mm auf. Bevorzugte Winkel liegen in Bereich von 20 bis 50 Grad bezogen auf die Vertikale.The
Der unteren Rolle 202 ist ein Anschlag 212 zugeordnet. Er ist am Basiscontainer 1, und zwar an seinem dem Erweiterungselement 20 benachbarten Ende, angeordnet. Er weist die Form eines im wesentlichen vertikal verlaufenden Profils auf, das in dieser Ausführung über annähernd die gesamt Höhe des Basiscontainers 1 verläuft.The

Nunmehr erfolgt die Absenkung des Erweiterungselements 20 durch Betätigung der Hubvorrichtung 55 (
Dem Fachmann ist offensichtlich, dass der untere Anschlag 212 sowie der Schenkel des Führungselements 211 nicht notwendigerweise exakt vertikal ausgerichtet sein müssen. Ein zuverlässiges Absenken ist auch möglich, wenn diese beiden genannten Elemente aus der Vertikalen heraus verkippt sind.It is obvious to the person skilled in the art that the
Es ist dem Fachmann ebenfalls offensichtlich, dass zur Verminderung der Flächenpressung eine einzelne Rolle 201,202 auch durch eine Gruppe von Rollen (z.B. zwei oder drei Rollen, die an einem gemeinsamen Rahmen angeordnet sind) ersetzt werden kann. Anstatt den beschriebenen abrollbaren Elementen (Rollen 201,202) können alternativ auch gleitfähige Elemente eingesetzt werden. Als gleitfähiges Element kann z.B. ein Bolzen mit rechtwinkligen Querschnitt verwendet werden, wobei eine seiner Flächen gleitfähig (z.B. mittels einer gleitfähigen Beschichtung) ausgebildet ist.It will also be apparent to those skilled in the art that to reduce surface pressure, a
Der beschriebene Absenkbewegung ist vollständig reversibel. Durch Betätigung der Hubvorrichtung 55 (Verlängerung des linearen Aktuators) wird das Erweiterungselement 20 angehoben, bis es die stabile Lage gemäß
Nach dem der Absenkvorgang abgeschlossen ist, ergeben sich bei den Erweiterungselementen zwischen Oberkante Seitenwand und der Dachwand 4,5 jeweils trapezförmige Öffnungen 95 (
Anstatt an der Oberkante der Seitenwände können die Zusatzflächenelemente auch an der Dachwand 4,5 eines Erweiterungselements 10,20 klappbar angebracht sein, In einer weiteren Ausführung können die Zusatzflächenelemente in den Seitenwänden eines Erweiterungselements integriert sein, und zwar derart, dass die Seitenwände doppelwandig ausgebildet sind und das Zusatzflächenelement zwischen den beiden Wänden der Seitenwand angeordnet ist. Bei Bedarf können die Zusatzflächenelemente herausgefahren werden, z.B. mittels Federkraft. Hierzu wird auf die
In einer weiteren Ausführung können die Zusatzflächenelemente doppelwandig ausgeführt sein.In a further embodiment, the additional surface elements can be double-walled.
Zur Abdichtung können an den Zusatzflächenelementen oder an Basiscontainer oder Erweiterungselementen 10,20 Dichtungen, insbesondere Berührungsdichtungen, vorhanden sein.For sealing, 10,20 seals, in particular contact seals, may be present on the additional surface elements or on base containers or extension elements.
Selbstverständlich können die Zusatzflächenelemente 18,28 auch baulich getrennt von den Containerelementen als separate Bauteile transportiert werden, und bei Bedarf eingefügt werden.Of course, the additional surface elements 18,28 can also be structurally separated from the container elements transported as separate components, and inserted as needed.
Die in den Zeichnungen dargestellten Beispiele zeigen jeweils Ausführungen mit genau zwei Erweiterungselementen. Selbstverständlich sind auch Ausführungen mit genau einem oder mehr als zwei Erweiterungselementen möglich. Der Ausfahrvorgang sowie der Absenkvorgang geschieht analog zu den dargestellten Abläufen für die einzelnen Erweiterungselemente 10,20.The examples shown in the drawings each show versions with exactly two extension elements. Of course, versions with exactly one or more than two extension elements are possible. The extension process and the lowering process is analogous to the processes shown for the
