Description

Die Erfindung betrifft eine Teleskopstütze für den Baubereich, mit einem Außenrohr und mit einem darin axial verschiebbar angeordneten Innenrohr, das mittels einer Ausfallsicherung gegenüber einem Entfernen aus dem Außenrohr gesichert ist, wobei die Ausfallsicherung ein an dem Außenrohr angeordnetes Anschlagelement aufweist, an das wenigstens ein an dem Innenrohr angeordnetes Anschlagmittel zur Anlage bringbar ist.The invention relates to a telescopic support for the construction sector, with an outer tube and with an axially displaceably arranged therein inner tube, which is secured by means of a fail-safe against removal from the outer tube, wherein the fail-safe has a arranged on the outer tube stop element, to the at least one the inner tube arranged stop means can be brought to bear.

Derartige Teleskopstützen werden im Bausektor für vielfältige Abstützaufgaben verwendet und werden beispielswiese als Decken- oder Einrichtstützen zum Abstützen von Betonschalungen eingesetzt.Such telescopic supports are used in the construction sector for a variety of supporting tasks and are used for example as a ceiling or Einrichtstützen for supporting concrete formwork.

Aus der GB 755 831 A ist eine Teleskopstütze für den Baubereich bekannt geworden, bei der das Anschlagelement durch einen verjüngten Randabschnitt des zu dem telskopierbaren Ende der Teleskopstütze weisenden Endes des Außenrohres gebildet ist. Auch bei der Teleskopstütze gemäß der EP 1 273 740 B1 weist das Außenrohr ein durch einen solchermaßen verjüngten Querschnittsbereich gebildetes Anschlagelement auf. Die EP 0 625 622 A1 zeigt eine Teleskopstütze, bei der das Anschlagelement durch einen Wandungsabschnitt eines auf das eine Ende des Außenrohrs aufgeschweißten Rohrstücks mit im Vergleich zum Außenrohr geringerem Innendurchmesser gebildet ist. EP 1605116A zeigt eine Teleskopstütze für den Baubereich mit den Merkmalen des Oberbegriffes des Anspruches 1.From the GB 755 831 A is a telescopic support for the construction industry has become known in which the stop element is formed by a tapered edge portion of the telescoping end of the telescopic support end facing the outer tube. Also in the telescopic support according to the EP 1 273 740 B1 For example, the outer tube has a stop element formed by a cross-sectional area tapered in this way. The EP 0 625 622 A1 shows a telescopic support, in which the stop element is formed by a wall portion of a welded onto the one end of the outer tube pipe section with a smaller inner diameter compared to the outer tube. EP 1605116A shows a telescopic support for the construction sector with the features of the preamble of claim 1.

Die Herstellung gattungsgemäßer Teleskopstützen ist fertigungstechnisch aufwendig und daher kostenintensiv.The production of generic telescopic supports is technically complex and therefore expensive.

Aufgabe der Erfindung ist, eine Teleskopstütze der eingangs genannten Art mit einfachen konstruktiven Maßnahmen derart zu verbessern, dass sie einfacher und mit einem geringeren Kostenaufwand zu fertigen ist.The object of the invention is to improve a telescopic support of the type mentioned with simple constructive measures such that it is easier and less expensive to manufacture.

Vorteile der ErfindungAdvantages of the invention

Die Aufgabe wird erfindungsgemäß durch eine Teleskopstütze mit den in Anspruch 1 angegebenen Merkmalen gelöst.The object is achieved by a telescopic support with the features specified in claim 1.

Bei der erfindungsgemäßen Teleskopstütze ist das Anschlagelement erfindungsgemäß im Bereich eines Endes des Außenrohres vorgesehen, wobei das Anschlagelement die freie Querschnittsfläche des Außenrohrs zumindest teilweise verdeckt. Unter Verdecken der Querschnittsfläche wird in der vorliegenden Anmeldung dabei auch ein zumindest teilweises Vorstehen des Anschlagelements in den lichten Querschnitt des Außenrohres verstanden. Der mit der Erfindung verbundene Vorteil besteht im Wesentlichen darin, dass das Anschlagselement auf einfache Weise an dem Außenrohr angeordnet werden kann, ohne dass hierzu eine aufwändige Veränderung des Innenquerschnitts des Außenrohres bzw. ein Anschweißen von separaten Rohrstücken erforderlich ist. Je nach der gewählten Befestigungsart kann dabei eine robuste und gegenüber axial angreifenden Kräften hoch belastbare Ausziehbegrenzung des Innenrohrs verwirklicht werden. Das Anschlagelement ist nach der Erfindung vorzugsweise ohne separate Verbindungsmittel an dem Außenrohr befestigt und im einfachsten Fall lediglich im Presssitz an bzw. in dem Außenrohr angeordnet. Das Anschlagselement kann aber auch im Sinne eines Sprengrings in einer an dem Außenrohr angeordneten Nut bzw. über eine Rastverbindung oder eine bajonettverschlussartige Befestigung an dem Außenrohr angeordnet sein. Das Anschlagelement ist mit dem Außenrohr verbunden und dies im Bereich des freien Endes des Außenrohrs.In the telescopic support according to the invention, the stop element according to the invention is provided in the region of one end of the outer tube, wherein the stop element at least partially obscures the free cross-sectional area of the outer tube. Covering the cross-sectional area in the present application also means an at least partial projection of the stop element into the clear cross-section of the outer tube. The advantage associated with the invention consists essentially in that the stop element can be arranged in a simple manner on the outer tube, without the need for a complex change of the inner cross section of the outer tube or a welding of separate pipe sections is required. Depending on the selected type of fastening, a robust pull-out limiter of the inner tube, which is highly load-bearing against axially acting forces, can be realized. The stop element is preferably attached according to the invention without separate connection means on the outer tube and arranged in the simplest case only in a press fit on or in the outer tube. However, the stop element can also be arranged in the sense of a snap ring in a groove arranged on the outer tube or via a latching connection or a bayonet-type fastening to the outer tube. The stop element is connected to the outer tube and this in the region of the free end of the outer tube.

Nach einer bevorzugten Weiterbildung der Erfindung greift das Anschlagselement in ein an einer Mantelfläche des Außenrohrs angeordnetes Innen- und/oder Außengewinde des Außenrohrs ein, wobei eine besonders belastbare Anordnung des Anschlagselements dadurch erreicht wird, dass das Anschlagselement mit einem Außen- und/oder einem Innengewinde in das bzw. in die korrespondierenden Gewinde des Außenrohrs eingreift.According to a preferred embodiment of the invention, the stop element engages in a arranged on a lateral surface of the outer tube inner and / or outer thread of the outer tube, wherein a particularly resilient arrangement of the stop member is achieved in that the stop element with an outer and / or an internal thread engages in or into the corresponding thread of the outer tube.

Zwecks Sicherung des Anschlagelements gegenüber einem unbeabsichtigten Lösen aus seiner Montageposition hat es sich dabei in der Praxis als vorteilhaft erwiesen, dass dem Anschlagelement eine Ausdrehsicherung zugeordnet ist. Die Ausdrehsicherung kann dabei insbesondere eine an dem Anschlagelement angeordnete und in das Gewinde des Außenrohrs einschlagbare Sicherungslasche aufweisen. Das Anschlagelement, hier eine Einschlaglasche, greift in eine Durchtrittsöffnung des Außenrohrs.In order to secure the stop element against unintentional release from its mounting position, it has proven to be advantageous in practice that the stop element is assigned a Ausdrehsicherung. The Ausdrehsicherung may in particular have a arranged on the stop element and einschlagbare in the thread of the outer tube locking tab. The stop element, here an impact flap, engages in a passage opening of the outer tube.

Die Belastbarkeit des Anschlagselements gegenüber axialen Belastungen, wie diese insbesondere bei einem Einschieben eines verschmutzten Innenrohrs in das Außenrohr auftreten können, wird dadurch weiter verbessert, dass das Anschlagelement eine Stirnfläche, d.h. einen stirnseitigen Wandungsabschnitt, des einen Endes des Außenrohres zumindest teilweise überdeckt.The load capacity of the stop member against axial loads, as may occur in particular when a soiled inner tube is pushed into the outer tube, is further improved in that the stop element has an end face, i. an end wall portion, the one end of the outer tube at least partially covered.

Das Anschlagelement ist nach einer Ausführungsform der Erfindung vorzugsweise als Kappe oder als Hülse ausgebildet. Dadurch kann einerseits einem Eindringen von Verunreinigungen, beispielsweise Frischbeton, in das Innere des Außenrohres entgegengewirkt werden, was für eine wartungsarme und zuverlässige Funktion günstig ist. Andererseits kann das Anschlagselement dadurch als (Gleit-) Lager und zugleich als Abstreifelement für ein verunreinigtes Innenrohr dienen. Ist das Anschlagselement als Kappe oder als Hülse ausgebildet, so muss zur Schaffung eines Anschfagselements am Außenrohr keine zusätzliche Bearbeitung erfolgen.The stop element is preferably formed according to an embodiment of the invention as a cap or as a sleeve. As a result, on the one hand penetration of impurities, such as fresh concrete, can be counteracted in the interior of the outer tube, which is favorable for a low-maintenance and reliable function. On the other hand, the stop element thereby serve as a (sliding) bearing and at the same time as a stripping element for a contaminated inner tube. If the stop element is designed as a cap or as a sleeve, no additional processing must be carried out to create an attachment element on the outer tube.

Zwecks einer von der Orientierung des Innenrohrs in dem Außenrohr unabhängigen Funktion der Ausfallsicherung ist das Anschlagmittel des Innenrohrs vorzugsweise als aufgeweitetes, beispielsweise aufgebördeltes, Ende des Innenrohrs ausgebildet. Dadurch kann das Innenrohr selbst bei sehr großen angreifenden Kräften, wie diese in der Praxis auftreten können, nicht aus dem Außenrohr entfernt werden.For the purpose of a function of the failsafe independent of the orientation of the inner tube in the outer tube of the stop means of the inner tube is preferably formed as a flared, for example crimped, end of the inner tube. As a result, the inner tube can not be removed from the outer tube even with very large forces acting on it, as can occur in practice.

Damit das Anschlagelement selbst unter hohen Biegemomenten des ausgezogenen Innenrohrs nicht aus seiner montierten Position gelöst werden kann, weist das Innenrohr nach einer Weiterbildung der Erfindung wenigstens einen radialwärts über seine Außenmantelfläche seitlich vorstehenden Vorsprung auf, der von dem aufgeweiteten Ende des Innenrohrs, dem Anschlagmittel, axial beabstandet angeordnet ist. Der Vorsprung ist dabei vorzugsweise einstückig mit dem Innenrohr ausgebildet und insbesondere über einen Umformprozess am Innenrohr gefertigt. Der Vorsprung ist vorteilhafterweise in Gestalt einer Noppe oder eines Sickenvorsprung ausgebildet und kann sich in Umfangsrichtung des Innenrohrs über einen vorzugsweise großen Umfangswinkel erstrecken. Nach einer Ausführungsform der Erfindung können auch mehrere Vorsprünge vorgesehen sein, die entlang des äußeren Umfangs des Innenrohrs zueinander beabstandet aufgereiht sind und die vorzugsweise in einer zur Längsachse des Innenrohrs orthogonal angeordneten Ebene angeordnet sind.So that the stop element can not be released from its mounted position even under high bending moments of the extended inner tube, that has Inner tube according to a development of the invention, at least one radially over its outer circumferential surface laterally projecting projection, which is arranged axially spaced from the flared end of the inner tube, the stop means. The projection is preferably formed integrally with the inner tube and made in particular via a forming process on the inner tube. The projection is advantageously formed in the form of a nub or a bead projection and may extend in the circumferential direction of the inner tube over a preferably large circumferential angle. According to one embodiment of the invention, a plurality of projections may be provided, which are lined up along the outer circumference of the inner tube spaced from each other and which are preferably arranged in a plane orthogonal to the longitudinal axis of the inner tube.

Das Innenrohr ist zwecks einer verbesserten Positioniergenauigkeit sowie eines zu-verlässigen Stützverhaltens an dem Anschlagelement und/oder an einer Innenmantelfläche des Außenrohres, vorzugsweise im Gleitspiel-Formschluss, axial geführt. Dabei ist das Innenrohr an der Innenmantelfläche des Außenrohrs zweckmäßiger Weise mit dem einen Anschlagsmittel, hier beispielsweise mit dem aufgebördelten Rand seines in dem Außenrohr angeordneten Endes, und/oder mit dem wenigstens einen Vorsprung geführt.The inner tube is axially guided for the purpose of improved positioning accuracy as well as a reliable support behavior on the stop element and / or on an inner circumferential surface of the outer tube, preferably in sliding play positive engagement. In this case, the inner tube on the inner lateral surface of the outer tube expedient manner with the one stop means, here for example with the crimped edge of its arranged in the outer tube end, and / or out with the at least one projection.

Das vorzugsweise als Kappe ausgebildete Anschlagelement weist nach einer unter fertigungstechnischen Aspekten besonders bevorzugten Weiterbildung der Erfindung ein Innengewinde auf, das in ein Außengewinde des Außenrohrs eingreift, wobei das Außengewinde zusätzlich mit einem Innengewinde einer Absenkmutter im Eingriff steht, an der ein quer zur Längsachse der Teleskopstütze durch das Außen- und Innenrohr führbarer Sicherungsbolzen abstützbar ist. Dadurch ist einerseits eine Feineinstellung der funktionellen Gesamtlänge der Teleskopstütze sowie ein erleichtertes Ausschalen möglich, andererseits kann das Anschlagelement unmittelbar auf ein ohnehin vorgesehenes Gewinde aufgeschraubt werden. Das Anschlagelement fungiert dabei zugleich im Sinne einer Kontermutter bzw. eines Anschlagelements für die Absenkmutter, so dass diese unverlierbar an der Teleskopstütze angeordnet ist.The trained preferably as a cap stop element has, according to a particularly preferred manufacturing aspects of the invention an internal thread which engages in an external thread of the outer tube, wherein the external thread is additionally engaged with an internal thread of a lowering nut on which a transverse to the longitudinal axis of the telescopic support can be supported by the outer and inner tube feasible securing bolt. As a result, on the one hand a fine adjustment of the overall functional length of the telescopic support and a simplified stripping possible, on the other hand, the stop element can be screwed directly onto an already provided thread. The stop element acts at the same time in the sense of a lock nut or a stop element for the lowering nut, so that it is arranged captive on the telescopic support.

Im Hinblick auf eine besonders kostengünstige Fertigung der Teleskopstütze weist das Außenrohr vorzugsweise über seine gesamte axiale Länge einen im Wesentlichen gleichbleibenden Innendurchmesser auf.With regard to a particularly cost-effective production of the telescopic support, the outer tube preferably has a substantially constant inner diameter over its entire axial length.

Insgesamt hat die erfindungsgemäße Baustütze den Vorteil, dass sie einfachst zu montieren (Endmontage) ist. Das Außen- wie auch Innenrohr können ohne Zusatzelemente bearbeitet und hergestellt werden und erst beim Zusammenfügen des Außen- und Innenrohres wird die Absenkmutter mit den damit verbundenen Elementen auf das Außenrohr aufgeschraubt. Ebenfalls wird vor dem Zusammenfügen des Innenrohrs mit dem Außenrohr der Sicherungsbolzen am Außenrohr angebracht. Ist die Baustütze erfindungsgemäß zusammengefügt kann der Sicherungsbolzen nur noch im Bereich der Durchstecköffnung verwendet werden, sofern das Anschlagelement einen Außendurchmesser aufweist, der größer ist, als die lichte Weite eines das Außenrohr umfassenden Abschnitts des entsprechend geformten Sicherungsbolzens.Overall, the prop of the invention has the advantage that it is easy to assemble (final assembly). The outer and inner tube can be edited and manufactured without additional elements and only when assembling the outer and inner tube, the lowering nut is screwed with the associated elements on the outer tube. Also, the fuse pin is attached to the outer tube prior to assembly of the inner tube with the outer tube. If the prop is assembled according to the invention, the securing bolt can only be used in the region of the insertion opening, provided that the stop element has an outer diameter which is greater than the inside diameter of a section of the correspondingly shaped securing bolt which surrounds the outer tube.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In der Fig. 1 ist eine insgesamt mit 10 bezeichnete Teleskopstütze für den Baubereich in einem ausgewählten Stützenabschnitt wiedergegeben. Die Teleskopstütze 10 weist ein Außenrohr 12 und ein darin axial verschiebbar angeordnetes Innenrohr 14 auf. Das Innenrohr 14 weist an seinem in der Figur oben dargestellten freien Ende 16 eine an sich bekannte Tragplatte 18 auf, während das Außenrohr 12 an seinem in der Fig. nicht näher wiedergegebenen fussseitigen Ende eine Fußplatte für ein sicheres Positionieren auf einem jeweiligen Untergrund aufweist.In the Fig. 1 is a generally designated 10 telescopic support for the construction sector in a selected column section reproduced. The telescopic support 10 has an outer tube 12 and an inner tube 14 arranged axially displaceable therein. The inner tube 14 has at its in the figure above shown free end 16 a known support plate 18 , while the outer tube 12 has a foot plate for secure positioning on a respective substrate at its not shown in detail in Fig. Foot end.

An einem kopfseitigen, d.h. der Tragplatte 18 des Innenrohrs 14 zugewandten, Ende 20 des Außenrohrs 12 ist eine Kappe 22 angeordnet, die als Anschlagelement für das Innenrohr 14 dient und durch die ein axiales Entfernen bzw. ein Ausfallen des Innenrohrs 14 aus dem Außenrohr 12 verhindert ist.On a head-side, ie the support plate 18 of the inner tube 14 facing the end 20 of the outer tube 12, a cap 22 is arranged, which serves as a stop element for the inner tube 14 and by the axial removal or a failure of the inner tube 14 from the outer tube 12 is prevented is.

Die Kappe 22 ist in einer zu einer Überwurfmutter entsprechenden Weise ausgebildet und weist einen im Wesentlichen zylindrischen Wandabschnitt 24 mit einem Innengewinde 26 auf. An den zylindrischen Wandabschnitt 24 schließt sich ein in der Fig. oberhalb des zylindrischen Wandabschnitts 24 angeordneter Randbereich 28 der Kappe 22 an, der gegenüber dem zylindrischen Wandbereich 24 radial in Richtung auf eine Längsachse 30 der Teleskopstütze 10 hin abgewinkelt ist und der eine freie Querschnittsfläche 32 des Außenrohrs 12 teilweise überdeckt.The cap 22 is formed in a manner corresponding to a cap nut and has a substantially cylindrical wall portion 24 with an internal thread 26 . Adjoining the cylindrical wall section 24 is an edge region 28 of the cap 22 which is arranged above the cylindrical wall section 24 and which is angled radially in the direction of a cylindrical longitudinal axis 30 of the telescopic support 10 and which has a free cross-sectional surface 32 the outer tube 12 partially covered.

Die Kappe 22 bzw. deren Innengewinde 26 befindet sich im Eingriff mit einem auf der äußeren Mantelfläche 34 des Außenrohrs 12 angeordneten Außengewinde 36. In das Außengewinde 36 des Außenrohrs 12 greift zugleich eine sogenannte Absenkmutter 38 ein, an der eine Handhabe 38' verschwenkbar angeordnet ist und die durch Verdrehen um die Längsachse 30 der Teleskopstütze 10 axial an dem Außenrohr 12 entlang bewegbar ist.The cap 22 and its internal thread 26 is in engagement with a arranged on the outer circumferential surface 34 of the outer tube 12 external thread 36. In the external thread 36 of the outer tube 12 also engages a so-called Lowering nut 38 , on which a handle 38 ' is pivotally mounted and which is axially movable by rotation about the longitudinal axis 30 of the telescopic support 10 on the outer tube 12 along.

An der Absenkmutter 38 ist ein quer zur Längsachse 30 der Teleskopstütze 10 durch das Außen- und Innenrohr 12, 14 gesteckter Sicherungsbolzen 40 abgestützt. Das Außenrohr 12 weist diesbezüglich zwei einander gegenüberliegende und parallel zur Längsachse 30 der Teleskopstütze 10 längserstreckte erste Durchstecköffnungen (Langlöcher) 42 auf, während das Innenrohr 14 eine Mehrzahl kreisförmiger einander gegenüberliegender (fluchtend) zweiter Durchstecköffnungen 44 aufweist, die längs des Innenrohrs 14 in jeweils zueinander regelmäßigen Abständen unter- bzw. übereinander angeordnet sind.At the lowering nut 38 is a transversely to the longitudinal axis 30 of the telescopic support 10 through the outer and inner tube 12, 14 plugged securing bolt 40 is supported. The outer tube 12 has in this respect two opposite and parallel to the longitudinal axis 30 of the telescopic support 10 elongated first through openings (slots) 42 , while the inner tube 14 has a plurality of circular opposing (aligned) second through-openings 44 which along the inner tube 14 in each case Periodically under or over each other are arranged.

Zur ungefähren Längeneinstellung der Teleskopstütze 10 wird das Innenrohr 14 zunächst bis zu einer gewünschten Länge der Teleskopstütze 10 ausgezogen und der Sicherungsbolzen 40 nachfolgend durch die ersten Durchstecköffnungen 42 des Außenrohrs sowie mit diesen jeweils fluchtenden zweiten Durchstecköffnungen 44 des Innenrohrs14 gesteckt.For approximate length adjustment of the telescopic support 10, the inner tube 14 is first pulled out to a desired length of the telescopic support 10 and the locking bolt 40 subsequently inserted through the first through-insertion openings 42 of the outer tube and with these each aligned second insertion openings 44 of the inner tube 14.

Durch Verdrehen der in der Fig. unterhalb des Sicherungsbolzens 40 angeordneten Absenkmutter 38 kann nachfolgend deren relative Position längs des Außenrohres 12 stufenlos verändert werden. Dadurch kann zugleich die axiale Abstützposition des Sicherungsbolzens 40 an dem Außenrohr 12 bzw. des mit diesem gekoppelten Innenrohrs 14 längs des Außenrohrs 12, d.h. die Länge der Teleskopstütze 10, bedarfsgerecht feinreguliert werden.By rotating the lowering nut 38 arranged below the securing bolt 40 in FIG. 1, its relative position along the outer pipe 12 can be subsequently changed steplessly. As a result, at the same time the axial support position of the securing bolt 40 on the outer tube 12 and the coupled thereto with the inner tube 14 along the outer tube 12, i. the length of the telescopic support 10, be fine-tuned as needed.

Wie insbesondere aus der Fig. 2, einem über einen Teilbereich der Teleskopstütze 10 gezeigten Längsschnitt, hervorgeht, überdeckt die Kappe 22 mit ihrem abgewinkelten Randbereich eine Stirnfläche 46 des einen Endes 20 des Außenrohres 12. Das Innenrohr 14 weist ein als aufgeweitetes Ende ausgebildetes Anschlagmittel 48 auf, das zwecks Ausfallsicherung des Innenrohrs 14 aus dem Außenrohr 12 an die Kappe 22 bzw. an deren abgewinkelten Randbereich 28 zur Anlage bringbar ist, sofern keine weiteren Sicherungselemente wirksam sind.As in particular from the Fig. 2 , a longitudinal section shown over a partial region of the telescopic support 10, the cap 22 with its angled edge region covers an end face 46 of the one end 20 of the outer tube 12. The inner tube 14 has a stop means 48 designed as a widened end, for the purpose of fail-safe protection of the inner tube 14 from the outer tube 12 to the cap 22 and at its angled edge portion 28 can be brought to bear, provided that no further securing elements are effective.

Das Innenrohr 14 weist zusätzlich mehrere noppenartige Vorsprünge 50 auf, die zu dem Anschlagmittel (aufgeweitetes Ende) 48 des Innenrohrs 14 beabstandet angeordnet sind und die radialwärts über eine Außenmantelfläche 34 des Innenrohrs 14 seitlich vorstehen. Die noppenartigen Vorsprünge 50 sind bei Erreichen einer vorbestimmten maximalen Auszugsweite des Innenrohrs 14 an der Kappe 22 zur Anlage gebracht und erzwingen so eine im Außenrohr 12 verbleibende Mindestlänge des Innenrohrs 14. Bei auftretenden Biegemomenten stützt sich das Innenrohr 14 daher an einer Innenmantelfläche 52 des Außenrohrs 12 ab, wodurch ein Abhebeln der Kappe 22 von dem Außenrohr 12 sicher vermieden wird.The inner tube 14 additionally has a plurality of knob-like projections 50 , which are arranged at a distance from the stop means (widened end) 48 of the inner tube 14 and project laterally radially beyond an outer lateral surface 34 of the inner tube 14. The knob-like projections 50 are brought into contact with the cap 22 upon reaching a predetermined maximum extension of the inner tube 14 and thus enforce a remaining in the outer tube 12 minimum length of the inner tube 14. When bending moments occur, the inner tube 14 is therefore supported on an inner circumferential surface 52 of the outer tube 12th from, whereby a levering of the cap 22 is reliably avoided by the outer tube 12.

Die noppenartigen Vorsprünge 50 haben eine Funktion wie das Anschlagmittel 48 und begrenzen die Teleskopierlänge der Teleskopstütze.The knob-like projections 50 have a function as the stop means 48 and limit the Teleskopierlänge the telescopic support.

Das Innengewinde 26 der Kappe 22 ist, wie in den Fign. 3 und 4 näher gezeigt ist, als Flachprofil ausgeführt und weist ein längs des Gewindes unterbrochenes Gewindeprofil 54 auf.The internal thread 26 of the cap 22 is, as in the FIGS. 3 and 4 is shown in more detail, designed as a flat profile and has a thread profile 54 interrupted along the thread.

Aus der Darstellung in der Fig. 4 ist ersichtlich, dass an dem zylindrischen Kappenabschnitt 24 der Kappe 22 eine als Einschlaglasche ausgebildete Aufdrehsicherung 56 angeordnet ist, die nach Aufschrauben der Kappe auf das Außengewinde 36 (Fig. 1 und 2) des Außenrohrs 12 in das Außengewinde 36 des Außenrohrs 12 eingeschlagen wird und die sich in einer Öffnung 57 (siehe Fig. 5) im Außengewinde 36 des Außenrohrs 12 festkrallt.From the representation in the Fig. 4 It can be seen that on the cylindrical cap portion 24 of the cap 22 is designed as a turn-tab Aufrehsicherung 56 is arranged, which after screwing the cap on the external thread 36 (FIGS. Fig. 1 and 2 ) of the outer tube 12 is hammered into the external thread 36 of the outer tube 12 and in an opening 57 (see Fig. 5 ) festkrallt in the external thread 36 of the outer tube 12.

In der Fig. 5 sind die Einzelteile der erfindungsgemäßen Teleskopstütze 10 vor dem Zusammenfügen des Innenrohrs 14 mit dem Außenrohr 12 gezeigt. An dem Innenrohr 14 ist bereits die vorstehend erläuterte Stützplatte 18 angeschweißt, während an dem fußseitigen Ende des Außenrohrs 12 eine Fußplatte 58 angeschweißt ist. Die Absenkmutter 38 ist auf das Außengewinde 36 des Außenrohrs 12 geschraubt und der Sicherungsbolzen 40 ist auf den Gewindebereich des Außenrohrs 12 oberhalb der Absenkmutter 38 aufgeschoben, während die Kappe 22 auf das Innenrohr 14 aufgeschoben und durch die noppenartigen Vorsprünge 50 bzw. die Tragplatte 18 gegenüber einem axialen Entfernen von dem Innenrohr 14 gesichert ist. Zum Zusammenfügen des Innenrohrs 14 mit dem Außenrohr 12 wird das Innenrohr 14 mit seinem aufgeweiteten Endes 48 (Anschlagmittel) soweit an dem kopfseitigen Ende 20 des Außenrohrs 12 axial in das Außenrohr 12 eingeschoben, bis zumindest die noppenartigen Vorsprünge 50 innerhalb des Außenrohrs 12 zu liegen kommen. Nachfolgend wird die Kappe 22 auf das Außengewinde 36 des Außenrohrs 12 aufgeschraubt und die Einschlaglasche 56 mit einem Werkzeug in die Öffnung 57 des Außenrohrs 12 eingeschlagen.In the Fig. 5 the individual parts of the telescopic support 10 according to the invention are shown prior to assembly of the inner tube 14 with the outer tube 12. On the inner tube 14, the above-explained support plate 18 is already welded, while at the foot-side end of the outer tube 12, a foot plate 58 is welded. The lowering nut 38 is screwed onto the external thread 36 of the outer tube 12 and the securing bolt 40 is pushed onto the threaded portion of the outer tube 12 above the lowering nut 38, while the cap 22 is pushed onto the inner tube 14 and the nub-like projections 50 and the support plate 18 opposite an axial removal of the inner tube 14 is secured. For joining the inner tube 14 with the outer tube 12, the inner tube 14 with its expanded end 48 (stopper) as far as inserted at the head end 20 of the outer tube 12 axially into the outer tube 12 until at least the knob-like projections 50 come to rest within the outer tube 12. Subsequently, the cap 22 is screwed onto the external thread 36 of the outer tube 12 and the Einschlaglasche 56 taken with a tool in the opening 57 of the outer tube 12.
