Abstract

The invention creates a tube assembly system for empty pipes and lighting tubes, for the construction of exhibition stands and shops, and their fitment with shelves, tables, cloakroom stands, supports for advertising media, lighting systems, railings, seating furniture, cabinets and the like, in which the tube ends can be connected by means of two-piece plug-in pins which can be expanded by means of hollow-headed screws which are inserted into the two pin halves and can hence be clamped into the tube ends. In order that no holes need to be provided in the ends of the tubes to be connected, and to allow the tubes to be arranged such that they are protected against rotation before assembly, the pin is surrounded by two half-shells which have an external tooth system which can be latched into a corresponding internal tooth system on the tubes, and both half-shells have an external ring which, in the assembled state of the plug-in pin, is located between the tube ends and has a hole for actuating a hollow-headed screw which is inserted into the two pin halves.

Description

Die Erfindung betrifft ein Rohrmontagesystem entsprechendThe invention relates accordingly to a pipe mounting system

dem Oberbegriff des Anspruchs 1.the preamble of claim 1.

Bei den bekannten Rohrmontagesystemen dieser Art sind in den Steckdorn Inbusschrauben eingesetzt, von denen jeweils wenigstens eine im Bereich der zu verbindenden Rohrenden liegt. Die Rohrenden haben Bohrungen, um die im Steckdorn befindlichen Schrauben betätigen zu können. Im montierten Zustand liegen die Rohrenden aneinander an.In the known pipe mounting systems of this type are in the plug mandrel Allen screws used, of which at least one in the area to be connected Pipe ends. The pipe ends have holes around those in the mandrel To be able to operate screws. In the assembled state, the pipe ends lie against one another at.

Nachteilig ist bei diesem Rohrverbindungsystem, daß alle Rohrenden Bohrungen aufweisen müssen, da eine Ausbildung der Bohrungen erst bei der Montage zu einer Beschädigung der auf die Rohr aufgebrachten Lackschicht führen kann.The disadvantage of this pipe connection system is that all pipe ends Must have holes, since the holes are only formed during assembly can damage the paint layer applied to the pipe.

Ein weiterer Nachteil ist darin zu sehen, daß nach dem Einsetzen des Steckdorns und vor dem Auseinanderdrücken der Steckdornhälften eine relative Verdrehung der Rohre in Umfangsrichtung möglich ist.Another disadvantage is that after the onset of the Plug mandrel and a relative rotation before pushing apart the plug mandrel halves the pipes in the circumferential direction is possible.

Der Erfindung liegt die Aufgabe zurundc, das Rohrmontagesystem der eingangs genannten Art so auszubilden, daß die Rohrenden frei von Bohrungen sind und sich bei der Montage vor dem Auseinanderspreizen der Dornhälften verdrehungssicher anordnen lassen.The invention has for its object zurundc, the pipe mounting system of to be designed in such a way that the pipe ends are free of bores and secure against twisting during assembly before the mandrel halves are spread apart let arrange.

Gelöst wird diese Aufgabe gemäß der Erfindung durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by the in the characterizing Part of claim 1 specified features.

Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Appropriate refinements of the invention emerge from the subclaims.

Die Außenverzahnung der Halbschalen, die durch entsprechenden Vorsprünge in axialer Richtung und in Umfangsrichtung am Dorn festgelegt werden können, und die Innenverzahnung an den Rohrenden ermöglicht es, die Rohre in Umfangsrichtung vel-drellungssicher anzuordnen, bevor die beiden Dornhälften unter Verwendung eines Inbusschlüssels aus- einandergespreizt werden. Zum Auseinanderspreizen der Dornhälften wird ein Inbusschlüssel in die Bohrung eingesetzt, die sich in dem die Halbschalen umgebenden Ring befindet. Zum Auseinanderspreizen der Dornhälften ist nur eine einzige Inbusschraube erforderlich. Da sich diese in dem Ring befindet, der im montierten Zustand zwischen den Rohrenden liegt, brauchen die Rohrenden keine Bohrungen aufzuweisen. Das Einsetzen des Dorns in die Rohrenden kann so erfolgen, daß die Bohrung im Ring der Halbschalen zum Beispiel von der Außenseite eines Messestandes nicht sichtbar und/oder leicht zugänglich ist.The external toothing of the half-shells by means of corresponding projections can be set in the axial direction and in the circumferential direction on the mandrel, and the internal teeth on the pipe ends make it possible to move the pipes in the circumferential direction to be arranged so as to be secure against twisting before the two halves of the mandrel using a Allen key be spread apart. To spread apart of the mandrel halves, an Allen key is inserted into the hole in the the ring surrounding the half-shells is located. For spreading the mandrel halves apart only a single Allen screw is required. Since this is in the ring, which lies between the pipe ends in the assembled state, the pipe ends do not need any To have holes. The mandrel can be inserted into the pipe ends in such a way that that the hole in the ring of the half-shells, for example, from the outside of a trade fair stand is not visible and / or easily accessible.

Der Ring an den Halbschalen hat zweckmäßigerweise eine solche Dicke, daß er im montierten Zustand mit der Außenfläche der Rohre abschließt; seine Farbe kann den Rohren angepaßt oder zu diesen kontrastierend sein.The ring on the half-shells expediently has a thickness such that that it is flush with the outer surface of the tubes in the assembled state; its color can be adapted to the tubes or contrasting with them.

Die Rohre und der Dorn können aus Aluminium und die Halbschalen aus Kunststoff bestehen.The tubes and the mandrel can be made of aluminum and the half-shells Made of plastic.

Die Erfindung wird nachstehend anhand der Fig. 1 und 2 beispielsweise erläutert. Es zeigt: Fig. 1 einen Längsschnitt und Fig. 2 einen Querschnitt des zwei Rohrenden verbindenden Rohrmontagesystems.The invention is illustrated below with reference to FIGS. 1 and 2, for example explained. It shows: FIG. 1 a longitudinal section and FIG. 2 a cross section of the Pipe mounting system connecting two pipe ends.

Das in den Fig. 1 und 2 gezeigte Rohrmontagesystem hat einen Dorn 11, der durch Teilung in Längsrichtung aus einer oberen Dornhälfte 12 und einer unteren Dornhälfte 13 besteht. Beide Dornhälften sind in die Enden zweier Rohre 18 eingesetzt.The pipe mounting system shown in Figures 1 and 2 has a mandrel 11, which is divided in the longitudinal direction from an upper mandrel half 12 and a lower mandrel half 13 is made. Both mandrel halves are in the ends of two tubes 18 used.

In den beiden Dornhälften 12 und 13 sitzt eine Inbus- schraube 21, und zwar derart, daß sich ihr Kopf in der oberen Dornhälfte 12 und ihr Schaft in der unteren Dornhälfte 13 befindet. Auf dem Inbusschraubenkopf ist eine Unterlegscheibe 27 angeordnet. Beide Dornhälften sind von zwei Halbschalen 14, 15 umschlossen, die beiden Halbschalen 14, 15 weisen einen Außenring 19 auf, dessen eine Hälfte sich auf der einen und dessen andere Hälfte sich auf der anderen Halbschale befindet. Im montierten Zustand schließt der Außenring 19 mit der-Außenfläche der Rohre 18 bündig ab.In the two mandrel halves 12 and 13 there is an Allen screw 21, in such a way that its head in the upper half of the mandrel 12 and its shaft in the lower mandrel half 13 is located. There is a washer on the Allen screw head 27 arranged. Both mandrel halves are enclosed by two half-shells 14, 15, the two half-shells 14, 15 have an outer ring 19, one half of which is on one half and its other half is on the other half-shell. In the assembled state, the outer ring 19 closes with the outer surface of the tubes 18 flush.

Wie Fig. 2 zeigt, haben beide Halbschalen 14, 15 eine Außenverzahnung 16, die in eine entsprechende Innenverzahnung 17 der Rohre eingreift.As FIG. 2 shows, both half-shells 14, 15 have external teeth 16, which engages in a corresponding internal toothing 17 of the tubes.

Die beiden Halbschalen 14, 15 haben Vorsprünge 22, die in entsprechende Ausnehmungen 23 der Dornhälften 12, 13 eingreifen und die Halbschalen gegenüber den Dornhälften in Umfangsrichtung festlegen.The two half-shells 14, 15 have projections 22 in corresponding Recesses 23 of the mandrel halves 12, 13 engage and the half-shells opposite fix the mandrel halves in the circumferential direction.

Die Halbschalen 14, 15 greifen mit vorspringenden Rändern 24 über die voneinander abgewandten Enden der Dornhälften 12, 13 und legen dadurch die Halbschalen gegenüber den Dornhälften in axialer Richtung fest.The half-shells 14, 15 overlap with protruding edges 24 the ends of the mandrel halves 12, 13 facing away from one another and thereby place the half-shells with respect to the mandrel halves in the axial direction.

Die beiden Dornhälften 12, 13 sind von Längsbohrungen 25 durchsetzt, die zur Aufnahme von elektrischen Leitungen dienen können, wenn die Rohre 18 als Lichtrohre verwendet werden und Ausschnitte zur Aufnahme von Beleuchtungskörpern aufweisen. Die Längsbohrungen 25 sind so ausgebildet, daß sie anteilsgleich in den Dornhälften 12 und 13 liegen.The two mandrel halves 12, 13 are penetrated by longitudinal bores 25, which can serve to accommodate electrical lines when the tubes 18 as Light pipes are used and cutouts to accommodate lighting fixtures exhibit. The longitudinal bores 25 are formed so that they are proportionately in the Mandrel halves 12 and 13 are located.

Die Hälften des in die Rohre 18 eingesetzten Dorns 11 können mittels eines Inbusschlüssels 26 auseinandergespreizt werden, der über eine radiale Bohrung 20 im Ring 19 der oberen Halbschale und eine entsprechende verlängernde Bohrung in der oberen Dornhälfte 12 in die Inbusschrauben 21 eingesetzt wird.The halves of the mandrel 11 inserted into the tubes 18 can by means of an Allen key 26 are spread apart, which has a radial bore 20 in the ring 19 of the upper half-shell and a corresponding elongated hole in the upper mandrel half 12 in the Allen screws 21 inserted will.
