Description

Die Erfindung betrifft einen Kübel aus Kunststoff, insbesondere.für den Transport und die Verarbeitung von Fertigmörtel, von pyramidenstumpfförmiger Gestalt mit einer Randverstärkung aus einem in den Kunststoff eingebetteten Rohr, welches im Bereich der schmaleren Seitenwände unter einem stumpfen Winkel abgebogen ist, dessen Scheitel nach oben weist, und welches im Bereich des Scheitelpunktes durch zwei Handgrifflöcher frei liegt.The invention relates to a bucket made of plastic, in particular for the transport and processing of ready-mixed mortar, of a truncated pyramid shape with an edge reinforcement made of a tube embedded in the plastic, which is bent at an obtuse angle in the region of the narrower side walls, the apex of which is upward points, and which is exposed in the area of the apex by two handle holes.

Ein derartiger Kunststoffkübel ist aus der DE-PS 27 08 45o bekannt geworden. Dieser für Mörtel geschaffene Kübel weist eine gewebeverstärkte Kunststoffwandung auf, die den aus Stahl bestehenden Verstärkungsrahmen in Umfangsrichtung der Rahmenteile voll umgreift, in Erstreckungsrichtung der Rahmenteile aber Bereiche des Rahmens freiläßt, die als Ösen für Kranhaken oder dergleichen dienen, wobei an der Außenseite des Behälters Verstärkungsrippen angeordnet sind. Die Herstellung aus gewebeverstärktem Kunststoff ist sehr arbeitsaufwendig. Daher werden solche Kübel in der Herstellung recht teuer. Die Herstellung solcher gewebeverstärkter Kunststoffkübel ist für eine Großserienfertigung nicht geeignet.Such a plastic bucket has become known from DE-PS 27 0 8 45o. This bucket created for mortar has a fabric-reinforced plastic wall that fully encompasses the reinforcement frame made of steel in the circumferential direction of the frame parts, but leaves areas of the frame open in the direction of extension of the frame parts that serve as eyelets for crane hooks or the like, with reinforcing ribs on the outside of the container are arranged. The production of fabric-reinforced plastic is very labor intensive. Therefore, such buckets are quite expensive to manufacture. The manufacture of such fabric-reinforced plastic buckets is not suitable for large-scale production.

Für die Großserienherstellung hingegen geeignet ist das Spritzgußverfahren, mit dem Kübel aus Kunststoff hergestellt werden können. Auf diese Weise wurde ein Kübel nach dem DE-GM 18 54 763 hergestellt, dessen Rand eine Umbördelung und unter der Umbördelung eine Wulst aufweist, über die ein geschlossener Ring aus einem Stahlrohr gepreßt werden kann, der durch die Wulst einen festen Sitz zwischen der Wulst und der Umbördelung erhält. Derartig freiliegende Stahlverstärkungsringe haben sich aber in der Praxis nicht bewährt, weil ein derartiger Kübel keine Ösen oder Handgrifflöcher aufweisen kann, ohne erheblich an Festigkeit zu verlieren.On the other hand, suitable for mass production is the injection molding process with which buckets can be made from plastic. In this way, a bucket was produced according to DE-GM 18 54 763, the edge of which has a bead and a bead under the bead, through which a closed ring can be pressed from a steel tube, which is firmly seated between the bead by the bead and the flanging gets. Exposed steel reinforcement rings of this type have not proven themselves in practice, however, because such a bucket cannot have eyelets or handle holes without losing considerable strength.

Bewährt hingegen haben sich Kübel nach der DE-PS 11 49 292, die eine Randverstärkung in Form eines ringförmig gebogenen Metallrohres aufweisen, welches vom Kunststoff völlig umgeben ist und mindestens an einer Stelle ihres Umfanges einen Stoß aufweisen, wobei die Enden des Metallrohres mittels einer einschiebbaren Innen- oder einer überschiebbaren Außenmuffe miteinander verbunden sind. Bei diesem Kübel sind zwei einander gegenüberliegende Teilausschnitte des Rohres, das die Randverstärkung bildet, nicht umspritzt, sondern liegen frei und dienen als Griffe oder als Angriffsflächen von Kranhaken.On the other hand, buckets according to DE-PS 11 49 292, which have an edge reinforcement in the form of an annularly bent metal tube, which is completely surrounded by the plastic and have an abutment at least at one point on their circumference, have proven effective, the ends of the metal tube being able to be inserted by means of an insertable one Inside or a push-on outer sleeve are connected to each other. In this bucket, two opposing partial sections of the tube that forms the edge reinforcement are not overmolded, but are exposed and serve as handles or as attack surfaces for crane hooks.

Probleme treten hier allerdings auf, wenn die Kübel eine pyramidenstumpfförmige Form haben und durch Einhängen in Kranhaken transportiert werden. Dann ist merkwürdigerweise die Stabilität der Randverstärkung schlechter als bei kegelstumpfförmigen Kübeln. Pyramidenstumpfförmige Kübel werden aber gern für den Transport auf Transportfahrzeugen benutzt, weil dann die rechteckige Ladefläche der Transportfahrzeuge besser ausnutzbar ist.Problems arise here, however, if the buckets have a truncated pyramid shape and are transported by hanging in crane hooks. Then, strangely, the stability of the edge reinforcement is worse than that of truncated cones Buckets. However, truncated pyramid-shaped buckets are often used for transport on transport vehicles because the rectangular loading area of the transport vehicles can then be used better.

Der Transport dieser Kunststoffkübel bereitet aber auch dann Schwierigkeiten, wenn für das Anheben und Transportieren des Kübels die Gabel eines Gabelstaplers benutzt wird, die unter den nach außen gewölbten Rand des Kübels greifen soll. Denn die Auflageflächen des Randes sind schmal und darüber hinaus noch,gewölbt.The transport of these plastic buckets is also difficult when the fork of a forklift is used to lift and transport the bucket, which should reach under the outwardly curved edge of the bucket. Because the contact surfaces of the edge are narrow and, moreover, curved.

Es ist die Aufgabe der Erfindung, einen billig als Massenartikel herstellbaren pyramidenstumpfförmigen Kübel zu schaffen, der sich durch hohe Stabilität und einfache Formgestaltung auszeichnet und der besonders gut für einen Transport mit Transportwerkzeugen geeignet ist, die unter den oberen Rand des Kübels angreifen, wie z.B. Gabeln eines Gabelstaplers.It is the object of the invention to provide a truncated pyramid-shaped bucket which can be mass-produced cheaply, which is characterized by high stability and simple design and which is particularly well suited for transport with transport tools which engage under the upper edge of the bucket, e.g. A forklift forks.

Die Erfindung verbessert den Kübel der eingangs genannten Art und löst die ihr zugrunde liegende Aufgabe dadurch, daß der verwendete Kunststoff der einstückig hergestellten Kunststoffteile des Kübels ein Polyolefin ist, daß die aus diesem Polyolefin hergestellten Wandungen zumindest an den Längsseitenwänden über die Wölbung hinaus in einen nach unten verlaufenden Wandungsteil nach Art einer Krempe so fortgesetzt sind, daß die Kübelwandung und der die Krempe bildende Wandungsteil parallel zueinander verlaufen oder einen spitzen Winkel einschließen, daß zwischen der Kübelwandung und dem die Krempe bildenden Wandungsteil eine Vielzahl von Querrippen angeordnet sind, deren Unterkante mit der Unterkante des die Krempe bildenden Wandungsteiles fluchtet und über ihren längeren Teil parallel zum Kübelboden verläuft, daß die Randverstärkung aus zwei gleichgeformten Rohrteilen in den Mitten der Längsseiten durch zwei übergeschobene Muffen verbunden ist, und daß am Rande der Handgrifflöcher vertikal sich nach unten erstreckende kurze Rippen angeordnet sind, deren Breite der Breite des rohrverstärkten Randes des Kübels entspricht.The invention improves the bucket of the type mentioned and solves the problem on which it is based in that the plastic used for the one-piece plastic parts of the bucket is a polyolefin, that the walls made of this polyolefin, at least on the long side walls, extend beyond the curvature into one bottom wall part are continued in the manner of a brim so that the bucket wall and the wall part forming the brim run parallel to one another or enclose an acute angle that between the A large number of transverse ribs are arranged in the bucket wall and the wall part forming the brim, the lower edge of which is aligned with the lower edge of the wall part forming the brim and runs parallel to the bucket bottom over its longer part, so that the edge reinforcement consists of two uniformly shaped tubular parts in the middle of the long sides by two pushed over Sockets is connected, and that vertically downwardly extending short ribs are arranged on the edge of the handle holes, the width of which corresponds to the width of the tube-reinforced edge of the bucket.

Ein solcher Kübel läßt sich billig als Massenartikel im Spritzgußverfahren herstellen, wozu sich insbesondere als Kunststoff Polyäthylen eignet. Die hterbei aufzuwendende Handarbeit ist äußerst gering, sie besteht lediglich im Einlegen der Rohr- und Muffenteile in die Spritzgußform. Diese werden zwischen Stiften, die sich in der Randverstärkung als vertikal auf die Rohrmitte radial gerichtete Löcher abdrücken und durch Vorsprünge in der Form, die sich als vertikal verlaufende, seitlich am Rohr tangential anliegende Schlitze im Kunststoff abdrücken, genauestens in der Spritzgußform zentriert, so daß die Stärke des das Stahlrohr und die Muffen umgebenden Kunststoffes überall gleich ist. Das ist ganz wesentlich für die Stabilität des Kübels. Darüber hinaus sind am Rande der Handgrifflöcher vertikal sich nach unten erstreckende kurze Rippen angeordnet, deren Breite der Breite des rohrverstärkten Randes entspricht. Diese Rippen bewirken ein Verhindern des Ausreißens des Rohres aus dem umgebenden Kunststoffbett bzw. ein Aufreißen des Randes des Kunststoffes.Such a bucket can be cheaply produced as a mass-produced article by injection molding, for which purpose polyethylene is particularly suitable as a plastic. The manual work involved is extremely low, it only consists of inserting the pipe and socket parts into the injection mold. These are precisely centered in the injection mold between pins, which are expressed in the edge reinforcement as holes which are directed radially vertically onto the tube center, and by projections in the shape, which are expressed as vertical slots in the plastic which are tangential to the side of the tube, so that the thickness of the plastic surrounding the steel pipe and the sleeves is the same everywhere. This is very important for the stability of the bucket. In addition, vertically downwardly extending short ribs are arranged on the edge of the handle holes, the width of which corresponds to the width of the tube-reinforced edge. These ribs prevent the pipe from being torn from the surrounding art fabric bed or tearing open the edge of the plastic.

Mit diesem Kübel läßt sich Frischmörtel leicht auf Fahrzeugen und an Kranhaken transportieren. Die Kübel weisen eine hohe Lebensdauer auf, obwohl sie ohne Gewebeverstärkung hergestellt sind.With this bucket, fresh mortar can be easily transported on vehicles and on crane hooks. The buckets have a long lifespan, even though they are made without reinforcement.

Diese Gestaltung des Kübels bringt auch den Vorteil mit sich, daß der Rand auf einer großen Fläche der Gabel aufliegt, was nicht nur die Stabilität des Kübels während des Transportes erhöht, sondern darüber hinaus auch noch den Vorteil mit sich bringt, daß der Kübel viel weniger leicht von der Gabel bei starkem Bremsen des Transportfahrzeuges abrutscht. Durch die vergrößerte Auflagefläche rutscht nicht ein Teil des Randes von der Gabel ab. Das führt dazu, daß der Kübel sich unter der in ihm befindlichen Last nicht so stark wie bei den herkömmlichen Gestaltungen verformt. Diese Wirkung wird durch die Vielzahl der Querrippen verstärkt, weil die Auflage über die gesamte Länge der Längsseitenwände gesichert ist.This design of the bucket also has the advantage that the edge rests on a large area of the fork, which not only increases the stability of the bucket during transport, but also has the advantage that the bucket is much less easily slips off the fork when the transport vehicle brakes hard. Due to the enlarged contact surface, part of the edge does not slip off the fork. As a result, the bucket does not deform as much under the load in it as in the conventional designs. This effect is enhanced by the large number of cross ribs, because the support is secured over the entire length of the long side walls.

Diese Kübel weisen auch keine am Boden angeordneten Tragtraversen parallel zur Kübelquerachse auf. Zweckmäßig ist es jedoch, unter dem Boden Rippen von der Stärke der Kübelwandungen anzuordnen, um zu verhindern, daß der Boden durch ein Schleifen beim Aufstellen an der Stellfläche mit der Zeit dünner wird. Diese Rippen dienen somit nicht so sehr der Verstärkung und Versteifung der Kübelform, sondern lediglich einer Verhinderung des Abschleifens des Bodenmaterials und einer Verhinderung des dadurch auftretenden Dünnerwerdens der Bodenwandung des Kübels.These buckets also have no crossbeams arranged on the floor parallel to the bucket transverse axis. However, it is expedient to arrange ribs of the thickness of the bucket walls under the floor, in order to prevent the floor from becoming thinner over time due to grinding when it is set up on the standing surface. These ribs are therefore not so much used to reinforce and stiffen the bucket shape, but only to prevent it Grinding of the soil material and preventing the thinning of the bottom wall of the bucket as a result.

Zweckmässig ist es, wenn an den Längsseitenwänden je ein Paar sich vertikal nach unten erstreckender Rippen angeordnet ist, deren Länge und Breite den Rippen neben den Handgrifflöchern entspricht.It is expedient if a pair of vertically downwardly extending ribs is arranged on the longitudinal side walls, the length and width of which correspond to the ribs next to the handle holes.

Zweckmäßig ist es, wenn der innen liegende Schlitz an der Randverstärkung eine Grundfläche aufweist, die abgewinkelt ist.It is useful if the internal slot on the edge reinforcement has a base that is angled.

Vorteilhaft ist es, wenn der Abstand der Querrippen voneinander kleiner als der doppelte Abstand der Kübelwandung von dem die Krempe bildenden Wandungsteil ist. Denn je dichter der Abstand der Querrippen voneinander ist, umso höher ist die Stabilität und umso besser werden die gegen Deformation besonders gefährdeten mittleren Wandungsteile geschützt. Dabei kann es durchaus den Vorteil haben, wenn die Querrippen nicht parallel zueinander angeordnet sind, sondern jeweils zwei benachbarte Querrippen einen spitzen Winkel miteinander einschließen, also z.B. V- oder W-förmig gestaltet ist. Aber auch eine U-förmige Gestaltung, bei der der die beiden Schenket miteinander verbindende bogenförmige Teil nach außen gerichtet ist, kann von besonderem Vorteil sein, nämlich dann, wenn das Transportwerkzeug auf der Auflagefläche für den Rand des Kübels nach oben gerichtete Erhebungen aufweist, die in den zwischen den von den Querrippen, dem die Krempe bildenden Wandungsteil und der Kübelwandung eingeschlossenen Fächern eingreift. Derartige Erhebungen auf der Oberfläche des Transportwerkzeuges sichern eine besonders gute Stabilität des Kübels während des Transportes. In diese Taschen können aber auch unter Umständen Kranhaken eingehängt werden.It is advantageous if the distance of the transverse ribs from one another is less than twice the distance of the bucket wall from the wall part forming the brim. Because the closer the cross ribs are to each other, the higher the stability and the better the central wall parts, which are particularly vulnerable to deformation, are protected. It can have the advantage if the transverse ribs are not arranged parallel to one another, but rather two adjacent transverse ribs each form an acute angle with one another, that is to say, for example, V or W-shaped. But also a U-shaped design, in which the arcuate part connecting the two legs is directed outwards, can be of particular advantage, namely when the transport tool on the support surface for the edge of the bucket has upward elevations that in between the of the Cross ribs engages the wall part forming the brim and the compartments enclosed. Such elevations on the surface of the transport tool ensure particularly good stability of the bucket during transport. Under certain circumstances, crane hooks can also be hung in these pockets.

Für die Herstellung ist es besonders vorteilhaft, wenn der die Krempe bildende Wandungsteil in einer senkrecht zum Kübelboden verlaufenden Ebene liegt.It is particularly advantageous for the production if the wall part forming the brim lies in a plane running perpendicular to the bucket bottom.

Die Rohre 4 treten lediglich in einem Teilbereich der Seitenwände ohne Kunststoffummantelung hervor, und zwar im Bereich der als Hand- oder Kranhakenlöcher dienenden Ausnehmungen 7. Zu beiden Seiten dieser Ausnehmungen 7 befindet sich eine kurze, nach unten gerichtete Rippe 8, die eine Verstärkung der Kunststoffummantelung 6 im Bereich des Randes darstellt.

The side walls 1, 2 are provided with an edge reinforcing tube 4 and sleeves 5 comprising an edge 6 at the top. The tubes 4 and the sleeves 5 are completely surrounded by plastic in the area of the long sides 1. The tubes 4 only emerge in a partial area of the side walls without plastic sheathing, in the area of the recesses 7 serving as hand or crane hook holes. On both sides of these recesses 7 there is a short, downwardly directed rib 8 which reinforces the plastic sheathing 6 represents in the area of the edge. These ribs 8 prevent the plastic sheathing 6 from tearing out where the tube 4 emerges from the plastic sheathing 6. In the middle of the handle or crane hook hole 7, the tube 4 is angled at an obtuse angle, preferably 40 °. The apex of this bend points upwards. The sleeves 5 connecting the two pipe parts 4 are arranged in the middle of the long sides.

Der Boden 3 weist auf der Unterseite Rippen 9 auf, deren Höhe nur gering ist und zweckmäßigerweise der Stärke des Wandungsmateriales entspricht. Diese Rippen haben weniger eine Verstärkungsfunktion als vielmehr die Funktion zu verhindern, daß beim Schleifen des Kübels auf dem Boden das Bodenmaterial abgeschliffen wird.The bottom 3 has ribs 9 on the underside, the height of which is only small and suitably corresponds to the thickness of the wall material. These ribs have less of a reinforcing function than the function of preventing the soil material from being ground down when the bucket is being ground on the ground.

Wie aus den Fig. 3 bis 5 am besten ersichtlich, weist die Kunststoffummantelung 6 im Bereich der Randverstärkung Löcher lo auf, die sich vertikal und radial zur Mitte des Rohres 4 erstrekken. Diese Löcher stammen von Stiften in der Spritzgußform, die der horizontalen Zentrierung des .Rohres 4 während des Spritzgießens dienten. Neben diesen Paaren von Löchern lo in der Ummantelung 6 weist die Ummantelung 6 noch Schlitze 11 und 12 auf, die ebenfalls während des Spritzvorganges zur Zentrierung des Rohres 4 in der Spritzgußform gedient hatten. Diese Schlitze 11, 12 verlaufen im wesentlichen vertikal und tangential zum Rohr 4. Sie können eckig oder gerundet sein. Sie stammen von Vorsprüngen in der Form, die der Zentrierung des Rohres 4 dienten. Diese Löcher und Schlitze dienen nach dem Öffnen der Spritzgußform zur Kontrolle dafür, daß die Ummantelung 6 um das Rohr 4 überall gleich stark ist.As best seen in FIGS. 3 to 5, the plastic sheath 6 has holes lo in the area of the edge reinforcement, which ver extend tical and radial to the center of the tube 4. These holes originate from pins in the injection mold, which were used for the horizontal centering of the tube 4 during the injection molding. In addition to these pairs of holes lo in the sheathing 6, the sheathing 6 also has slots 11 and 12, which also served to center the tube 4 in the injection mold during the injection molding process. These slots 11, 12 run essentially vertically and tangentially to the tube 4. They can be angular or rounded. They come from projections in the shape that were used to center the tube 4. After opening the injection mold, these holes and slots serve to check that the sheathing 6 around the tube 4 has the same thickness everywhere.

Der Schlitz 12 weist eine Grundfläche auf, die abgewinkelt ist und einen Winkel von vorzugsweise 135° einschließt. Durch diese Abwinkelung ist erreicht, daß nahtlos der Kunststoff.der Wandung in den Kunststoff der UmmantelUng übergeht. Zentrierlöcher können auch dort angebracht sein, wo sich die Muffe 5 befindet. Diese Zentrierlöcher und Zentrierschlitze 11, 12 sind für die Haltbarkeit der Kübel von großer Wichtigkeit, weil durch sie die überall gleichmäßige Stärke der Kunststoffummantelung gesichert ist. Diese Löcher lo und Schlitze 11, 12 verbinden im allgemeinen nicht das Rohr 4 mit der Außenatmosphäre, weil sich während des Spritzgußvorganges am Boden der Löcher lo und der Schlitze 11, 12 ein sehr dünnes Kunststoffhäutchen ausgebildet hat.The slot 12 has a base which is angled and encloses an angle of preferably 135 °. This bending ensures that the plastic of the wall merges seamlessly into the plastic of the casing. Centering holes can also be made where the sleeve 5 is located. These centering holes and centering slots 11, 12 are of great importance for the durability of the buckets because they ensure the uniform thickness of the plastic sheathing. These holes 10 and slots 11, 12 generally do not connect the tube 4 to the outside atmosphere because a very thin plastic skin has formed at the bottom of the holes 10 and the slots 11, 12 during the injection molding process.

Um auf der Gabel 17 eines Transportwagens 18 gut transportiert werden zu können, ist der obere Rand 6 mit seiner nach außen verlaufenden Wölbung über diese hinaus mit einem Wandungsteil 19 nach Art einer Krempe nach unten fortgesetzt. Dieser Wandungsteil 19 verläuft entweder parallel zur Längsseitenwand 1 oder unter einem spitzen Winkel, zweckmässigerweise jedoch senkrecht zum Kübelboden 3. Zwischen diesem Wandungsteil 19 und der Kübelwandung 1 ist eine Vielzahl von Querrippen 21 angeordnet, deren Unterkante mit der Unterkante des die Krempe bildenden Wandungsteiles 19 fluchtet und über ihren längeren Teil parallel zum Kübelboden verläuft. Zweckmässigerweise ist der Abstand A der Querrippen 21 voneinander kleiner als der doppelte Abstand B der Kübelwandung 1 von dem die Krempe bildenden Wandungsteil 19.In order to be able to be easily transported on the fork 17 of a transport carriage 18, the upper edge 6, with its curvature extending outwards, is continued downward beyond it with a wall part 19 in the manner of a brim. This wall part 19 runs either parallel to the longitudinal side wall 1 or at an acute angle, but expediently perpendicular to the bucket bottom 3. Between this wall part 19 and the bucket wall 1 there is a large number of transverse ribs 21, the lower edge of which is flush with the lower edge of the wall part 19 forming the brim and runs parallel to the bucket bottom over its longer part. The distance A between the transverse ribs 21 is expediently smaller than twice the distance B between the bucket wall 1 and the wall part 19 forming the brim.

In den geschnittenen Teilen der Fig. 1 und 2 sieht man die Anordnung dieser Querrippen - weggeschnitten ist hier ein Teil des die Krempe bildenden Wandungsteils 19 -. Aus Fig. 6 und 7 ist ersichtlich, daß die Querrippen senkrecht zur Längsseitenwand 1 und zu dem die Krempe bildenden Wandungsteil 19 verlaufen. Das aber muß nicht sein. Aus Fig. 8 ist ersichtlich, daß diese Querrippen auch eine andere Anordnung haben können, nämlich eine V-förmige Anordnung bei den Querrippen 15, eine W-förmige Anordnung bei den Querrippen 14 und eine U-förmige Anordnung bei den Querrippen 13.In the cut parts of FIGS. 1 and 2 one can see the arrangement of these transverse ribs - part of the wall part 19 forming the brim is cut away here. 6 and 7 that the transverse ribs are perpendicular to the longitudinal side wall 1 and to the wall part 19 forming the brim. But that doesn't have to be the case. From Fig. 8 it can be seen that these transverse ribs can also have a different arrangement, namely a V-shaped arrangement with the transverse ribs 15, a W-shaped arrangement with the transverse ribs 14 and a U-shaped arrangement with the transverse ribs 13.

Die Stabilität des Behälters läßt sich durch den Stahlrohrring 5 stark erhöhen. Ist ein solcher vorgesehen, so befinden sich die Querrippen 21, 13, 14, 15 unter der Wölbung, die der das Stahlrohr 4 ummantelnde Kunststoff bildet. Zweckmäßig ist die Höhe C der Querrippen 21 mindestens ebenso hoch,wie der Durchmesser des Stahlrohrverstärkungsringes 4, 5.The stability of the container can be through the Increase steel pipe ring 5 significantly. If such is provided, the transverse ribs 21, 13, 14, 15 are located under the curvature which the plastic encasing the steel tube 4 forms. The height C of the transverse ribs 21 is expediently at least as high as the diameter of the steel tube reinforcement ring 4, 5.

Es besteht auch die Möglichkeit, anstatt Muffen 5 über die Rohre 4 zu schieben, in die Rohre 4 Stäbe oder Rohre mit kleinerem Durchmesser einzuschieben.It is also possible, instead of pushing sleeves 5 over the tubes 4, into the tubes 4 to insert rods or tubes with a smaller diameter.
