Description

Die vorliegende Erfindung betrifft einen Verbindungsadapter zur Ausbildung einer koaxialen Verbindung zweier Mastteilstücke einer Mastbaugruppe.The present invention relates to a connection adapter for forming a coaxial connection of two mast sections of a mast assembly.

Stahl- oder Aluminiumrohrmasten sind aus dem Stand der Technik bekannt und finden beispielsweise als Träger für Beleuchtungsobjekte Verwendung. Traditionell werden diese Masten durch Verschweißen einzelner Mastteilstücke gefertigt. Dies ist mit einer nachteiligen Schwächung der Materialstruktur der Masten verbunden. Üblicherweise erfolgt das Schweißen im Werk, so daß ein aufwendiger und teurer Transport der fertigen Masten zum Aufstellort erforderlich ist.Steel or aluminum tube masts are known from the prior art and are used, for example, as a carrier for lighting objects use. Traditionally, these masts are made by welding individual mast sections. This is associated with an adverse weakening of the material structure of the masts. Usually, the welding takes place in the factory, so that a complex and expensive transport of the finished masts to the installation site is required.

In dem deutschen Gebrauchsmuster DE 203 07 432 U1 ist beschrieben, daß einzelne Mastteilstücke auch vor Ort montiert werden können. Hierfür ist ein unabhängig von den Mastteilstücken ausgebildeter Verbindungsadapter vorgesehen, der sowohl mit einem ersten Mastteilstück, als auch mit einem zweiten Mastteilstück eine formschlüssige Eingriffsverbindung ausbildet, die durch zusätzliche Sicherungsmittel, wie beispielsweise Klebstoff, Schrauben bzw. Nieten gesichert ist. Die Montage der Mastbaugruppe kann damit vor Ort durchgeführt werden. Sie ist jedoch nach wie vor sehr aufwendig, da die Anschlußenden der Mastteilstücke und die Anschlußteile des Verbindungsadapters stets in einem zusätzlichen Arbeitsschritt mit Hilfe der Sicherungsmittel gesichert werden müssen.In the German utility model DE 203 07 432 U1 It is described that individual mast sections can also be mounted on site. For this purpose, a trained independently of the mast sections connecting adapter is provided which forms both with a first mast section, as well as with a second mast section a positive engagement connection, which is secured by additional securing means, such as adhesive, screws or rivets. The assembly of the mast assembly can thus be carried out on site. However, it is still very expensive, since the terminal ends of the mast sections and the connecting parts of the connection adapter must always be secured in an additional step using the securing means.

Eine Aufgabe der vorliegenden Erfindung ist es, den Montageaufwand einer Mastbaugruppe gegenüber dieser bekannten Lösung deutlich zu verringern.An object of the present invention is to significantly reduce the assembly cost of a mast assembly over this known solution.

Diese Aufgabe wird durch einen Verbindungsadapter nach Anspruch 1 bzw. eine Mastbaugruppe nach Anspruch 17 gelöst. Danach ist es vorgesehen, daß zumindest eine kraftschlüssige Verbindung zwischen dem Verbindungsadapter und einem Mastteilstück ausgebildet wird. Hierdurch werden Verbindungsadapter und Mastteilstück in ihrer gegenseitigen Lage kraftschlüssig durch Reibung gehalten. Ein kraftschlüssiger, sicherer Halt des Mastteilstücks am Verbindungsadapter wird also bereits durch das Verbinden der beiden Werkstücke erzielt, ohne daß separate Sicherungsmittel, wie Klebstoff, Nieten, Schrauben ohne eine Schweißnaht eingesetzt werden müssen. Der Einsatz eines solchen zusätzlichen Sicherungsmittels ist nicht mehr notwendig und kann daher entfallen. Auch ohne ein Sicherungsmittel ist das Entfernen eines Mastteilstücks nicht mehr möglich. Dadurch entfällt auch der separate Arbeitsschritt (Kleben, Nieten, Schrauben, Schweißen, etc.) zum Sichern der Verbindung, wodurch der Aufwand für die Montage der Mastbaugruppe gegenüber herkömmlichen Lösungen deutlich verringert ist. In einer besonders vorteilhaften Ausführungsform der Erfindung ist eine paßschlüssige Verbindung zwischen den Mastteilstücken derart herstellbar, daß eine Lagekorrektur während oder im Anschluß an den Verbindungsvorgang nicht erforderlich ist.This object is achieved by a connection adapter according to claim 1 and a mast assembly according to claim 17. Thereafter, it is provided that at least one frictional connection between the connection adapter and a mast section is formed. As a result, connection adapter and mast section are held frictionally in their mutual position by friction. A non-positive, secure hold of the mast section on the connection adapter is thus already achieved by connecting the two workpieces without separate securing means, such as adhesive, rivets, screws without a weld must be used. The use of such an additional securing means is no longer necessary and can therefore be omitted. Even without a securing means the removal of a mast section is no longer possible. This also eliminates the separate step (gluing, riveting, screwing, welding, etc.) to secure the connection, whereby the cost of mounting the mast assembly compared to conventional solutions is significantly reduced. In a particularly advantageous embodiment of the invention, a fitting connection between the mast sections is such that a position correction during or after the connection process is not required.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben und werden anhand von Ausführungsbeispielen nachfolgend näher beschrieben. Hierbei zeigen:Advantageous embodiments of the invention are specified in the dependent claims and will be described in more detail below with reference to exemplary embodiments. Hereby show:

Der Mast 1 ist als Mastbaugruppe ausgeführt und umfaßt ein oberes Mastteilstück 5 und ein im Boden 3 verankertes unteres Mastteilstück 6. Das obere Mastteilstück 5 ist dabei mit dem unteren Mastteilstück 6 in einem Verbindungsbereich 7 mit Hilfe eines Verbindungsadapters 8 koaxial verbunden.The mast 1 is designed as a mast assembly and includes an upper mast section 5 and anchored in the bottom 3 lower mast section 6. The upper mast section 5 is connected to the lower mast section 6 coaxially in a connection region 7 by means of a connection adapter 8.

Oberes und unteres Mastteilstück 5, 6 sind aus Stahl gefertigt. Anstelle von Stahl kann jedoch auch Aluminium oder ein anderer Werkstoff verwendet werden. Beide Mastteilstücke 5, 6 sind als Rohre mit kreisrunden Querschnitten und im wesentlichen gleichbleibenden Durchmessern ausgebildet, wobei der Außendurchmesser des oberen Mastteilstücks 5 kleiner ist als der Innendurchmesser des unteren Mastteilstücks 6. Es sind jedoch auch andere Rohrquerschnitte möglich, beispielsweise dreieckige, viereckige oder mehreckige bzw. ovale.Upper and lower mast section 5, 6 are made of steel. However, instead of steel, aluminum or another material may be used. Both mast sections 5, 6 are formed as tubes with circular cross-sections and substantially constant diameters, wherein the outer diameter of the upper mast section 5 is smaller than the inner diameter of the lower mast section 6. However, other tube sections are possible, for example, triangular, square or polygonal or oval.

Das untere Mastteilstück 6 weist unterhalb des Verbindungsbereichs 7 eine mit einem Deckel 9 verschließbare Öffnung auf, hinter der sich im Inneren des unteren Mastteilstücks 6 eine elektrische Anschlußvorrichtung befindet, beispielsweise ein Kabelübergangskasten oder dergleichen (nicht dargestellt). Darüber hinaus weist das untere Mastteilstück 6 im Bereich des unteren Mastendes 10 ein durchgehendes Kabelloch 11 auf.The lower mast section 6 has below the connection region 7 a closable with a lid opening 9, behind which is located in the interior of the lower mast section 6, an electrical connection device, such as a cable junction box or the like (not shown). In addition, the lower mast section 6 has a continuous cable hole 11 in the region of the lower mast end 10.

Der Verbindungsbereich 7 der Mastbaugruppe sowie der zur Ausbildung der koaxialen Verbindung der beiden Mastteilstücke 5, 6 verwendete Verbindungsadapter 8 ist vergrößert in Fig. 2 abgebildet.The connection region 7 of the mast assembly and the connection adapter 8 used to form the coaxial connection of the two mast sections 5, 6 is enlarged in FIG Fig. 2 displayed.

Der Verbindungsadapters 8 besteht im wesentlichen aus einem Grundkörper 12. Der Grundkörper 12 weist im wesentlichen die Form eines Hohlzylinders, genauer eines geraden Kreiszylinders auf. Es sind jedoch auch andere Grundkörperformen möglich, wobei diese an die Querschnitte der Mastteilstücke 5, 6 angepaßt sind. Der Verbindungsadapter 8 weist an den Enden 13, 14 des Grundkörpers 12 jeweils einen axialen Anschlag 15, 16 auf. Der Anschlag 15 an dem in Richtung des ersten Mastteilstücks 5 weisenden Grundkörperende 13 ragt dabei radial nach außen, während der am gegenüberliegenden, in Richtung des zweiten Mastteilstücks 6 weisenden Grundkörperende 14 angeordnete Anschlag 16 radial nach innen ragt.The connecting adapter 8 consists essentially of a base body 12. The main body 12 has substantially the shape of a hollow cylinder, more precisely a straight circular cylinder. However, other basic body shapes are possible, these being adapted to the cross sections of the mast sections 5, 6. The connection adapter 8 has at the ends 13, 14 of the base body 12 in each case an axial stop 15, 16. The stop 15 on the pointing in the direction of the first mast section 5 base body end 13 protrudes radially outward, while at the opposite, pointing in the direction of the second mast section 6 base end 14 stop 16 projects radially inwardly.

Die innere Mantelfläche 17 des Grundkörpers 12 ist als erste Verbindungsfläche ausgebildet derart, daß der Grundkörper 12 im montierten Zustand das Verbindungsende 18 des ersten Mastteilstücks 5 umschließt. Anders ausgedrückt liegt das erste Mastteilstück 5 in einer Aufnahmeöffnung 19 des Verbindungsadapters 8 ein. Dabei stützt sich das Verbindungsende 18 des ersten Mastteilstücks 5 an dem radial nach innen ragenden Anschlag 16 des Verbindungsadapters 8 ab.The inner circumferential surface 17 of the main body 12 is formed as a first connecting surface such that the base body 12 in the assembled state, the connecting end 18 of the first mast section 5 encloses. In other words, the first mast section 5 is located in a receiving opening 19 of the connection adapter 8. In this case, the connecting end 18 of the first mast section 5 is supported on the radially inwardly projecting stop 16 of the connection adapter 8.

Die äußere Mantelfläche 20 des Grundkörpers 12 ist als zweite Verbindungsfläche ausgebildet. Das zweite Mastteilstück 6 weist eine Öffnung 21 zur Aufnahme des Verbindungsadapters 8 auf. Zwischen der äußeren Mantelfläche 20 und dem Verbindungsende 22 des zweiten Mastteilstücks 6 besteht im montierten Zustand eine kraftschlüssige Verbindung. Diese ist vorzugsweise als eine Preßpassung ausgebildet, bei der das Verbindungsende 22 des zweiten Mastteilstücks 6 den Grundkörper 8 des Verbindungsadapters 8 kraftschlüssig umhüllt. Anders ausgedrückt stellt das zweite Mastteilstück 6 eine Art Paßloch dar, während der Verbindungsadapter 8 als Paßzapfen dient.The outer circumferential surface 20 of the base body 12 is formed as a second connection surface. The second mast section 6 has an opening 21 for receiving the connection adapter 8. Between the outer circumferential surface 20 and the connecting end 22 of the second mast section 6 there is a frictional connection in the mounted state. This is preferably formed as a press fit, wherein the connecting end 22 of the second mast section 6, the base body 8 of the connection adapter 8 wrapped non-positively. In other words, the second mast section 6 a kind of fitting hole, while the connection adapter 8 serves as a fitting pin.

Zur Montage der Mastbaugruppe wird zunächst der Verbindungsadapter 12 mit dem Verbindungsende 18 des ersten Mastteilstücks 5 in der unten näher beschriebenen Art und Weise verbunden. Anschließend wird das erste, den Verbindungsadapter 12 tragende Mastteilstück 5 mit dem zweiten Mastteilstück 6 verbunden. Als besonders vorteilhaft hat es sich dabei erwiesen, daß eines der beiden Mastteilstücke fixiert wird, während das andere Mastteilstück, beispielsweise mit Hilfe einer Zugvorrichtung, axial auf das andere Mastteilstück zu bewegt wird derart, daß die beiden Mastteilstücke in Axialrichtung 23 aufeinander aufgesteckt werden. Beispielsweise wird das mit dem Verbindungsadapter 12 versehen erste Mastteilstück 5 in axialer Richtung 23 auf das feststehende zweite Mastteilstück 6 aufgeschoben. Ein exaktes Ausrichten der beiden Mastteilstücke 5, 6 aufeinander ist für den Fügevorgang nicht erforderlich. Vielmehr erfolgt durch das Aufschieben der Mastteilstücke 5, 6 aufeinander ein selbsttätiges Ausrichten in Axialrichtung 23. Um dieses selbsttätige Ausrichten zu erleichtern, läuft der Grundkörper 12 des Verbindungsadapters 8 an seinem dem zweiten Mastteilstück 6 zugewandten Ende 14 konisch zu, so daß sich eine Art umlaufende Anlaufschräge 24 ergibt. Das Fügen der beiden Mastteilstücke 5, 6 kann auf einfache Art und Weise nicht nur im Werk (stationäre Fertigung), sondern auch direkt vor Ort auf der Baustelle erfolgen (mobile Fertigung), ohne daß hierzu aufwendige Montagevorrichtungen erforderlich sind. Lediglich eine Vorrichtung zum Fixieren eines Mastteilstücks und zum Bewegen des anderen Mastteilstücks sind erforderlich. Diese Vorrichtung kann beispielsweise auf einem separaten Montagefahrzeug bereitgehalten werden oder aber bereits im Lieferfahrzeug integriert sein.For mounting the mast assembly, the connection adapter 12 is first connected to the connection end 18 of the first mast section 5 in the manner described in more detail below. Subsequently, the first mast section 5 carrying the connection adapter 12 is connected to the second mast section 6. To be particularly advantageous, it has been found that one of the two mast sections is fixed, while the other mast section, for example by means of a pulling device, axially to the other mast section is moved to such that the two mast sections are attached to each other in the axial direction 23. For example, the first mast section 5 provided with the connection adapter 12 is pushed onto the fixed second mast section 6 in the axial direction 23. An exact alignment of the two mast sections 5, 6 on each other is not required for the joining process. Rather, by pushing the mast sections 5, 6 successively an automatic alignment in the axial direction 23. To facilitate this automatic alignment, the base body 12 of the connection adapter 8 at its second mast section 6 end facing 14 conically, so that a kind of circumferential Run-on slope 24 results. The joining of the two mast sections 5, 6 can be done in a simple manner not only in the factory (stationary production), but also directly on site on the site (mobile production), without the need for complex mounting devices are required. Only a device for fixing a mast section and for moving the other mast section are required. For example, this device may be on a separate Assembly vehicle be kept or already integrated in the delivery vehicle.

Der Außendurchmesser 25 des Grundkörpers 12 des Verbindungsadapters 8 einerseits und der Innendurchmesser 26 des zweiten Mastteilstücks 6 andererseits sind derart aufeinander abgestimmt, daß sich durch ein Übermaß der vorgesehenen Preßpassung zwischen diesen beiden Werkstücken ein Kraftschluß ergibt. Mit anderen Worten werden der am ersten Mastteilstück 5 fixierte Verbindungsadapter 8 und das zweite Mastteilstück 6 in ihrer gegenseitigen Lage kraftschlüssig durch Reibung gehalten, wobei die Reibung durch eine Spannung erzeugt wird, die auf eine beim Fügen auftretende elastische Verformung zurückzuführen ist. Wie weiter unten erläutert wird, tritt die elastische Verformung erfindungsgemäß ausschließlich bei dem Verbindungsadapter 8 auf, während das zweite Mastteilstück 6 im wesentlichen unverformt bleibt. Hierdurch wird eine Beschädigung der Materialstruktur des zweiten Mastteilstücks 6 vermieden. Eine Übertragung der Form oder Struktur des Verbindungsadapters 8 auf das zweite Mastteilstück 6 durch den Fügevorgang findet nicht statt.The outer diameter 25 of the base body 12 of the connecting adapter 8 on the one hand and the inner diameter 26 of the second mast section 6 on the other hand are matched to one another, that results in an adhesion of the proposed interference fit between these two workpieces. In other words, the fixed to the first mast section 5 connection adapter 8 and the second mast section 6 are frictionally held in their mutual position by friction, wherein the friction is generated by a voltage that is due to an occurring during joining elastic deformation. As will be explained below, the elastic deformation according to the invention occurs exclusively in the connection adapter 8, while the second mast section 6 remains substantially undeformed. As a result, damage to the material structure of the second mast section 6 is avoided. A transfer of the shape or structure of the connection adapter 8 to the second mast section 6 by the joining process does not take place.

Innen- und Außendurchmesser des Grundkörpers 12 des Verbindungsadapters 8 sind - abgesehen von den Anschlägen 15, 16 - vorzugsweise jeweils über die gesamte Grundkörperlänge 27 konstant, wobei sich bei einer vollständigen Überlappung der axialen Positionen der Verbindungsflächen 17, 20 das in Fig. 2 dargestellte Bild ergibt. Insoweit sich die Verbindungsflächen 17, 20 überlappen, gewährleistet das erste Mastteilstück 5 durch seine Formstabilität während des Fügevorgangs eine sichere und unveränderliche Position des Verbindungsadapters 8. In weiteren Ausführungsformen der Erfindung muß es sich bei den Verbindungsflächen nicht zwingend um die innere und äußere Mantelfläche des Grundkörpers 12 handeln. Es ist daher ebenso möglich, die Verbindungsflächen 17, 20 derart vorzusehen, daß sie sich nur teilweise überlappen (nicht dargestellt).Inner and outer diameter of the base body 12 of the connection adapter 8 are - apart from the stops 15, 16 - preferably constant over the entire base length 27, wherein at a complete overlap of the axial positions of the connecting surfaces 17, 20, the in Fig. 2 displayed image results. Insofar as the connecting surfaces 17, 20 overlap, the first mast section 5 ensures a secure and invariable position of the connection adapter 8 due to its dimensional stability during the joining process The invention does not necessarily have to be about the inner and outer lateral surface of the basic body 12 in the case of the connecting surfaces. It is therefore also possible to provide the connecting surfaces 17, 20 so that they only partially overlap (not shown).

Ist der Verbindungsadapter 8 nur formschlüssig mit dem Verbindungsende 18 des ersten Mastteilstückes 5 verbunden, muß die der Preßlänge entsprechende Überlappungsbreite groß genug gewählt werden, um eine sichere Preßpassung zu gewährleisten. Die vorgesehene Preßlänge entspricht vorzugsweise mindestens dem 1,5fachen des Außendurchmessers 25 des Grundkörpers 12. Besonders vorteilhaft ist es, wenn die Preßlänge das 1,5 - 2fache des Durchmessers beträgt. Vorzugsweise entspricht die Grundkörperlänge 27 der Preßlänge, so daß für die Preßpassung der gesamte Grundkörper 12 ausgenutzt wird.If the connection adapter 8 is only positively connected to the connection end 18 of the first mast section 5, the overlap width corresponding to the press length must be selected large enough to ensure a secure interference fit. The intended pressing length preferably corresponds to at least 1.5 times the outer diameter 25 of the base body 12. It is particularly advantageous if the pressing length is 1.5 to 2 times the diameter. Preferably, the basic body length 27 corresponds to the pressing length, so that the entire basic body 12 is utilized for the interference fit.

Der Grundkörper 12 des Verbindungsadapters 8, wie vorzugsweise der gesamte Verbindungsadapter 8 selbst, ist aus einem elastisch verformbaren Material gefertigt, um die für die Preßpassung erforderliche Verformungsspannung bereitzustellen. Vorzugsweise besteht der Verbindungsadapter 8 aus einem Kunststoffmaterial, welches diese Eigenschaften aufweist. Durch die Verwendung eines elektrisch isolierenden Kunststoffes wird darüber hinaus eine elektrische Isolierung des ersten Mastteilstücks 5 zu dem zweiten Mastteilstück 6 sichergestellt. Dies ist insbesondere dann von Vorteil, wenn eines der Mastteilstücke 5, 6 aufgrund von äußeren Einwirkungen oder aufgrund sonstiger Ursachen, wie beispielsweise eine gelösten Kabelverbindung, Strom führt.The main body 12 of the connection adapter 8, as preferably the entire connection adapter 8 itself, is made of an elastically deformable material to provide the deformation stress required for the interference fit. Preferably, the connection adapter 8 is made of a plastic material which has these properties. Moreover, the use of an electrically insulating plastic ensures electrical insulation of the first mast section 5 relative to the second mast section 6. This is particularly advantageous when one of the mast sections 5, 6 due to external influences or due to other causes, such as a dissolved cable connection, current.

Mit der erfindungsgemäßen separaten Bereitstellung der Mastteilstücke 5, 6 und der Verbindung über den oben beschriebenen Verbindungsadapter 8 können beliebige Kombinationen von Mastteilstücken 5, 6 bereitgestellt werden. So ist es beispielsweise möglich, Mastteilstücke 5, 6 aus verschiedenen Materialien und/oder Oberflächen- bzw. Farbvarianten miteinander zu kombinieren. Beispielsweise kann der Mast 1 aus einem unteren Mastteilstück 6 aus Stahl und einem oberen Mastteilstück 5 aus Edelstahl oder aus einem unteren Mastteilstück 6 aus Edelstahl und einem oberen Mastteilstück 5 aus Aluminium bestehen.With the separate provision according to the invention of the mast sections 5, 6 and the connection via the connection adapter 8 described above, any desired combinations of mast sections 5, 6 can be provided. For example, it is possible to combine mast sections 5, 6 made of different materials and / or surface or color variants. For example, the mast 1 may consist of a lower mast section 6 made of steel and an upper mast section 5 made of stainless steel or a lower mast section 6 made of stainless steel and an upper mast section 5 made of aluminum.

Der Grundkörper 12 besteht vorzugsweise aus zwei baugleichen und miteinander verbindbaren halbschalenförmigen Grundkörperelementen 28, vgl. die in den Fig. 3 und 4 dargestellte erste Ausführungsform der Erfindung. Die Grundkörperelemente 28 umfassen im montierten Zustand das Verbindungsende 18 des ersten Mastteilstücks 5 nach Art einer Manschette, vgl. Fig. 5 (ebenfalls erste Ausführungsform). Zur Verbindung der beiden Grundkörperelemente 28 miteinander weisen diese eine Anzahl von zusammenwirkenden Verbindungselementen auf, die eine kraft- und/oder formschlüssige Verbindung herstellen. Bei den Verbindungselementen kann es sich dabei um Steck-, Rast- oder Schnappelemente handeln. Im vorliegenden Ausführungsbeispiel weisen die Grundkörperelemente 28 im Bereich der Anschläge 15, 16 Stecker 29 und korrespondierende Steckeröffnungen 30 auf. Die Verbindungselemente gewährleisten vorzugsweise ein dichtes Aneinanderanliegen der beiden Grundkörperelemente 28 derart, daß ein Eindringen von Wasser über den Verbindungsbereich 7 in das Innere des Verbindungsadapters 8 und damit in das Innere des zweiten Mastteilstücks 6 vermieden wird.The main body 12 preferably consists of two identical and interconnectable half-shell-shaped base body elements 28, cf. in the Fig. 3 and 4 illustrated first embodiment of the invention. The base body elements 28 in the assembled state comprise the connecting end 18 of the first mast section 5 in the manner of a sleeve, cf. Fig. 5 (also first embodiment). To connect the two basic body elements 28 with each other, these have a number of cooperating connecting elements, which produce a non-positive and / or positive connection. The connecting elements may be plug-in, latching or snap-action elements. In the present exemplary embodiment, the base body elements 28 have plugs 29 and corresponding plug openings 30 in the region of the stops 15, 16. The connecting elements preferably ensure a tight abutment of the two basic body elements 28 in such a way that the penetration of water through the connecting region 7 into the interior of the connecting adapter 8 and thus into the interior of the second mast section 6 is avoided.

Neben der ersten Ausführungsform ist nachfolgend auch eine zweite Ausführungsform beschrieben (Fig. 6, 7 und 8). Bei beiden Ausführungsformen erfolgt die Preßpassung durch eine elastische Verformung des Verbindungsadapters 8, genauer gesagt durch eine elastische Verformung der als Paßfläche dienenden zweiten Verbindungsfläche 20, also der äußeren Mantelfläche des Grundkörpers 12. Hierzu ist diese mit einer Anzahl voneinander beabstandeter und quer zur Axialrichtung 23 verlaufender Haltestege 31 versehen, die vorzugsweise einstückig am Grundkörper 12 angeformt, beispielsweise mit Hilfe eines Kunststoffspritzverfahrens angespritzt sind. Bei einem Aufschieben des zweiten Mastteilstücks 6 auf den am ersten Mastteilstück 5 montierten Verbindungsadapter 8 (oder umgekehrt) werden die Haltestege 31 elastisch verformt und gewährleisten die für eine sichere Preßpaßverbindung notwendige Verformungsspannung.In addition to the first embodiment, a second embodiment is also described below ( Fig. 6 . 7 and 8th ). In both embodiments, the interference fit is carried out by an elastic deformation of the connection adapter 8, more precisely by an elastic deformation of serving as a mating surface second connection surface 20, so the outer surface of the base body 12. For this purpose, this with a number of spaced and transverse to the axial direction 23 extending Holding webs 31 provided, which are preferably integrally formed on the base body 12, for example, injection-molded by means of a plastic injection molding process. When the second mast section 6 is pushed onto the connection adapter 8 mounted on the first mast section 5 (or vice versa), the retaining webs 31 are elastically deformed and ensure the deformation stress necessary for a secure press fit connection.

Zugleich kann auch die erste Verbindungsfläche 17 des Grundkörpers 12, also dessen innere Mantelfläche, mit einer Anzahl Haltestege 32 versehen sein. Dies ist insbesondere dann sinnvoll, wenn die beiden Grundkörperelemente 28 des Verbindungsadapters 8 nicht formschlüssig um das Verbindungsende 18 des ersten Mastteilstücks 5 nach Art einer Manschette herumgelegt werden, sondern wenn auch zwischen dem ersten Mastteilstück 5 und dem Verbindungsadapter 8 eine kraftschlüssige Verbindung in Form einer Preßpassung vorgesehen ist. In diesem Fall ist der Innendurchmesser 33 des Grundkörpers 12, welcher durch die Oberseiten 34 der innen liegenden Haltestege 32 definiert wird, geringer als der Außendurchmesser 35 des ersten Mastteilstücks 5, vgl. Fig. 5, so daß sich beim Fügen des ersten Mastteilstücks 5 auch die inneren Haltestege 32 elastisch verformen.At the same time, the first connection surface 17 of the main body 12, that is to say its inner lateral surface, can also be provided with a number of holding webs 32. This is particularly useful if the two basic body elements 28 of the connection adapter 8 are not wrapped around the connecting end 18 of the first mast section 5 in the manner of a cuff, but if between the first mast section 5 and the connection adapter 8 a frictional connection in the form of a press fit is provided. In this case, the inner diameter 33 of the main body 12, which is defined by the upper sides 34 of the inner holding webs 32, less than the outer diameter 35 of the first mast section 5, see. Fig. 5 , so that when joining the first mast section 5 and the inner retaining webs 32 deform elastically.

Anzahl, Form und Lage der Haltestege 31, 32 an den inneren und/oder äußeren Mantelflächen 17, 20 können entsprechend den an die Preßpassung gestellten Anforderungen in Abhängigkeit von der Belastung der Mastbaugruppe durch Wind und andere äußere Einflüsse usw. gewählt werden. Wie in den Fig. 3 bis 5 dargestellt, sind die Haltestege 31, 32, insbesondere die an der zweiten Verbindungsfläche 20 vorgesehenen Haltestege 31, im wesentlichen umlaufend angeordnet. Hierdurch wird eine besonders sichere Preßpassung ermöglicht.The number, shape and position of the retaining webs 31, 32 on the inner and / or outer lateral surfaces 17, 20 can be selected according to the requirements of the press fit depending on the load of the mast assembly by wind and other external influences. As in the Fig. 3 to 5 illustrated, the holding webs 31, 32, in particular provided on the second connection surface 20 holding webs 31, arranged substantially circumferentially. As a result, a particularly secure interference fit is possible.

In dem weiteren Ausführungsbeispiel (nicht dargestellt) weist der Grundkörper 12 des Verbindungsadapters 8 an seiner ersten und/oder zweiten Verbindungsfläche 17, 20 eine Anzahl voneinander beabstandeter und in Axialrichtung 23 verlaufender Axialstege auf. Diese Axialstege können anstelle der Haltestege 31, 32 zur Ausbildung einer Preßpaßverbindung verwendet werden, wobei sich die Axialstege selbst elastisch verformen.In the further embodiment (not shown), the base body 12 of the connection adapter 8 at its first and / or second connection surface 17, 20 a number of spaced-apart and extending in the axial direction 23 axial webs. This Axialstege can be used instead of the holding webs 31, 32 for forming a Preßpaßverbindung, wherein the Axialstege deform itself elastic.

Bei der in den Fig. 6 bis 8 dargestellten Ausführungsform weist der Grundkörper 12 des Verbindungsadapters 8 derartige Axialstege 36 auf. Die Stegkanten 37 der Axialstege 36 sind dabei deutlich abgerundet derart, daß während des Fügevorgangs keine Deformation des Mastmaterials erfolgt und die Materialstruktur des zweiten Mastteilstücks 6 nicht negativ beeinflußt wird. Zugleich sind wiederum quer zur Axialrichtung 23 angeordnete Haltestege 31 vorgesehen. Die Haltestege 31, die sich beim Fügen der Werkstücke zur Ausbildung der Preßpassung elastisch verformen, befinden sich bei dieser Ausführungsform auf den Oberseiten 38 der dann im wesentlichen starren oder nur wenig elastischen Axialstege 36. Die Oberseiten 38 der Axialstege 36 definieren mit anderen Worten in diesem Fall die zweite Verbindungsfläche 20 und damit die äußere Mantelfläche des Grundkörpers 12.In the in the Fig. 6 to 8 illustrated embodiment, the base body 12 of the connection adapter 8 on such axial webs 36. The web edges 37 of the axial webs 36 are significantly rounded in such a way that during the joining process, no deformation of the mast material and the material structure of the second mast section 6 is not adversely affected. At the same time again arranged transversely to the axial direction 23 holding webs 31 are provided. The holding webs 31, which elastically deform during the joining of the workpieces to form the press fit, are in this embodiment on the tops 38 of the then substantially rigid or only slightly elastic axial webs 36. The tops 38 of the axial webs 36 define with In other words, in this case, the second connection surface 20 and thus the outer surface of the base body 12th

Auch bei diesem Ausbildungsbeispiel können Axialstege 39 zusätzlich auf zweiten Verbindungsfläche 17, also der Mantelinnenfläche des Grundkörpers 12 vorgesehen sein und dort gegebenenfalls eine weitere Preßpassung mit dem ersten Mastteilstück 5 ausbilden.In this exemplary embodiment, axial webs 39 can additionally be provided on the second connecting surface 17, that is to say the inner surface of the base body 12, and optionally there form a further press fit with the first mast section 5.

Bei den dargestellten Ausführungsformen ist in dem radial nach innen weisenden Anschlag 16 des Grundkörpers 12 eine rechteckige Aussparung 40 vorgesehen. Diese dient zur Befestigung einer balkenförmigen Haltevorrichtung 41 für eine elektrische Anschlußvorrichtung. Die Haltevorrichtung 41 ist dabei an ihrem Befestigungsende mit einem Haken 42 versehen und hintergreift im montierten Zustand die Innenseite 43 des Anschlags 16, vgl. Fig. 7 und 8. Die Haltevorrichtung 41 reicht von dem Verbindungsadapter 8 bis in den Bereich der mit dem Deckel 9 verschließbaren Mastöffnung und garantiert damit - sofern sie aus einem elektrisch nicht leitenden Material gefertigt ist - eine isolierte und damit besonders sichere Aufhängung eines Kabelübergangskastens oder dergleichen. Alternativ kann die Haltevorrichtung auch einstückig mit dem Verbindungsadapter verbunden, beispielsweise an diesen angespritzt sein.In the illustrated embodiments, a rectangular recess 40 is provided in the radially inwardly facing stop 16 of the base body 12. This is used to attach a bar-shaped holding device 41 for an electrical connection device. The holding device 41 is provided at its attachment end with a hook 42 and engages in the mounted state, the inside 43 of the stopper 16, see. Fig. 7 and 8th , The holding device 41 extends from the connecting adapter 8 into the region of the lid opening 9 closable with the mast opening and thus guarantees - if it is made of an electrically non-conductive material - an insulated and thus particularly secure suspension of a cable transfer box or the like. Alternatively, the holding device may also be integrally connected to the connection adapter, for example, molded onto it.
