Description

Die Erfindung betrifft einen Schienenstrang für insbesondere Einschienen-Hängebahnen, mit einer oder mehreren Profillaufschienen, die durch jeweils wenigstens eine Gelenkverbindung miteinander gekoppelt sind, wobei die jeweilige Profillaufschiene einen Oberflansch und einen Unterflansch aufweist.The invention relates to a rail track for particular monorail monorails, with one or more profile rails, which are coupled to each other by at least one hinge joint, wherein the respective profile rail has a top flange and a bottom flange.

Ein solcher Schienenstrang wird beispielhaft in dem Gebrauchsmuster DE 297 03 939 U1 oder auch in der EP 0 112 457 A2 beschrieben. Vergleichbare Schienenstränge sind in großer Zahl und Ausgestaltung aus der Praxis bekannt. Eine Anforderung für solche Schienenstränge besteht darin, dass die wenigstens eine Gelenkverbindung bestimmte Längskräfte aufnehmen muss. Solche Längskräfte stellen sich dann ein bzw. können auftreten, wenn sich Einschienen-Hängebahnen über die Profillaufschienen bewegen und diese für die Kraftübertragung nutzen. Aus diesem Grund hat man in der Zwischenzeit verschiedene Gelenkverbindungen ebenso wie unterschiedliche Schienen-profile entwickelt. So existiert beispielsweise eine sog. "V-Schiene" der Anmelderin, die sich durch ein besonders hohes Widerstandsmoment auszeichnet (vgl. DE 296 04 431 U1 ).Such a rail track is exemplary in the utility model DE 297 03 939 U1 or in the EP 0 112 457 A2 described. Comparable rail tracks are known in large numbers and design from practice. A requirement for such rail tracks is that the at least one articulated connection must absorb certain longitudinal forces. Such longitudinal forces are then set or can occur when monorail overhead conveyors move over the profile rails and use them for power transmission. For this reason, in the meantime, different joint connections as well as different rail profiles have been developed. For example, there is a so-called "V-rail" of the applicant, which is characterized by a particularly high moment of resistance (see. DE 296 04 431 U1 ).

Dennoch besteht unverändert ein Bedürfnis dahingehend, Gelenkverbindungen und Profillaufschienen zur Verfügung zu stellen, die für große Längskräfte ausgelegt sind. Das gilt insbesondere für im Vergleich zu den "V-Schienen" einfacher aufgebaute E-Schienen, also Profillaufschienen, bei denen der Oberflansch und der Unterflansch jeweils "T-förmig" ausgestaltet ist, die also ein im Querschnitt "I-förmiges" Profil aufweisen, wie es beispielhaft in den Figuren 7 und 8 des Gebrauchsmusters DE 297 03 939 U1 dargestellt ist. Hier setzt die Erfindung ein.Nevertheless, there remains a need to provide articulated joints and profile rails that are designed for large longitudinal forces. This is especially true for compared to the "V-rails" simple design E-rails, ie profile rails, in which the upper flange and the lower flange in each case "T-shaped" is configured, which thus have a cross-sectionally "I-shaped" profile as exemplified in Figures 7 and 8 of the utility model DE 297 03 939 U1 is shown. This is where the invention starts.

Der Erfindung liegt das technische Problem zugrunde, einen derartigen Schienenstrang so weiterzuentwickeln, dass erhöhte Längskräfte bei einfachem konstruktiven Aufwand übertragen werden können.The invention is based on the technical problem of developing such a rail track so that increased longitudinal forces can be transmitted with a simple design effort.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Schienenstrang für insbesondere Einschienen-Hängebahnen im Rahmen der Erfindung dadurch gekennzeichnet, dass die Gelenkverbindung einen minimalen Querschnitt von wenigstens 6cm2 aufweist und aus einem Stahl mit einer Streckgrenze von wenigstens 300 N/mm2 hergestellt ist.To solve this technical problem, a generic rail track for particular monorail monorails in the invention is characterized in that the hinge has a minimum cross-section of at least 6cm 2 and is made of a steel with a yield strength of at least 300 N / mm 2 .

Insbesondere wird auf einen Querschnitt von wenigstens 7 cm2 zurückgegriffen. In diesem Zusammenhang wird meistens mit im Querschnitt I-förmigen Profillaufschienen gearbeitet, also den bereits angesprochenen so genannten E-Schienen bzw. Standardschienen. Selbstverständlich sind aber auch die V-Schienen entsprechend der DE 296 04 431 U1 nicht ausgeschlossen.In particular, recourse is had to a cross section of at least 7 cm 2 . In this context, working mostly with cross-section I-shaped profile rails, so the already mentioned so-called E-rails or standard rails. Of course, but also the V-rails are according to the DE 296 04 431 U1 not excluded.

Im Allgemeinen sind sowohl eine obere als auch eine untere Gelenkverbindung vorgesehen. Dabei ist erfindungsgemäß die untere Gelenkverbindung mit dem fraglichen minimalen Querschnitt von wenigstens 6 cm2 ausgerüstet, weil üblicherweise die obere Gelenkverbindung über einen größeren Querschnitt an dieser Stelle verfügt. D.h., für die auftretenden Längskräfte stellt die untere Gelenkverbindung die entscheidende Prüfstelle dar. Bei dieser unteren Gelenkverbindung ist nun deren minimaler Querschnitt mit einer Größe von wenigstens 6cm2 ausgerüstet. Meistens beträgt die Größe des minimalen Querschnittes der unteren Gelenkverbindung wenigstens 7 cm2.In general, both an upper and a lower hinge connection are provided. In this case, according to the invention, the lower hinge connection is equipped with the minimum cross section of at least 6 cm 2 in question, because usually the upper articulated connection has a larger cross section at this point. That is, for the occurring longitudinal forces, the lower joint connection is the crucial test site. In this lower joint connection is now their minimum cross-section with a size of at least 6cm 2 equipped. Mostly the size of the minimum cross-section of the lower hinge connection is at least 7 cm 2 .

I.V.m. der Tatsache, dass die Gelenkverbindung (und regelmäßig auch die Profillaufschiene als solche) jeweils aus einem Stahl mit einer Streckgrenze von wenigstens 300 N/mm2 ausgerüstet ist, lassen sich durch diese Bemessungsregel problemlos Längskräfte von 140 kN oder noch mehr aufnehmen. Tatsächlich kann nämlich die Streckgrenze des Stahls für die Herstellung der unteren Gelenkverbindung auch oberhalb von 350 N/mm2 angesiedelt sein. Geht man vorliegend von 300 N/mm2 aus und berücksichtigt einen minimalen Querschnitt von wenigstens 6 cm2 so errechnet sich aus diesen Vorgaben eine Kraft von ca. 180 kN, bis die Streckgrenze erreicht ist. Als Folge hiervon können Längskräfte von ca. 140 kN problemlos aufgenommen werden.IVm the fact that the articulated joint (and regularly also the profile rail as such) each made of a steel with a yield strength of at least 300 N / mm 2 is equipped, can be easily taken by this design rule longitudinal forces of 140 kN or even more. In fact, in fact, the yield strength of the steel for the production of the lower joint can also be above 350 N / mm 2 . Assuming in the present case of 300 N / mm 2 and takes into account a minimum cross section of at least 6 cm 2, a force of about 180 kN is calculated from these specifications until the yield strength is reached. As a result, longitudinal forces of about 140 kN can be easily absorbed.

Nach einem Vorschlag der Erfindung mit selbstständiger Bedeutung ist bei einem gattungsgemäßen Schienenstrang oder einem solchen, wie er zuvor bereits beschrieben wurde, des Weiteren vorgesehen, dass die einzige Gelenkverbindung bzw. die untere Gelenkverbindung eine Drehachse für zugelassene Schwenkbewegungen zwischen den jeweils benachbarten Profillaufschienen definiert. Dabei ist die Drehachse außerhalb eines Trennbereiches angesiedelt ist. Dieser Trennbereich bzw. Stoßbereich markiert den Spaltbereich zwischen den Profillaufschienen, welcher von dem Oberflansch und dem Untertlansch bzw. dessen Oberkante und Unterkante begrenzt wird. Tatsächlich arbeitet der Stand der Technik beispielsweise nach der DE 297 03 939 U1 an dieser Stelle mit einer Drehachse, welche an der unteren Kante des Trennbereiches bzw. im oder an dem Unterflansch angesiedelt ist. Erfindungsgemäß wird nun die Drehachse außerhalb dieses Trennbereiches verlagert.According to a proposal of the invention with independent significance is further provided in a generic rail track or such, as already described above, that the single articulation or the lower articulation defines an axis of rotation for authorized pivoting movements between the respective adjacent profile rails. The axis of rotation is located outside of a separation area. This separation area or impact area marks the gap area between the profiled rails, which is delimited by the upper flange and the lower flange or its upper edge and lower edge. In fact, the state of the art works according to the DE 297 03 939 U1 at this point with an axis of rotation, which is located at the lower edge of the separation area or in or on the lower flange. According to the invention, the axis of rotation is now displaced outside this separation area.

Dabei sind grundsätzlich zwei verschiedene Vorgehensweisen möglich. So kann die Drehachse unterhalb einer Unterkante der Profillaufschiene angeordnet sein. Alternativ oder zusätzlich hierzu ist es aber auch denkbar, dass die Drehachse in Längsrichtung der Profillaufschienen versetzt im Vergleich zum Trennbereich angeordnet wird. In jedem Fall sorgt der erfindungsgemäß verfolgte Versatz der Drehachse dafür, dass eine an den Profillaufschienen angreifende Längskraft sowohl an der oberen Gelenkverbindung als auch der unteren Gelenkverbindung angreift, sofern zwei solche Gelenkverbindungen realisiert sind, was meistens der Fall ist. Dabei verteilt sich die eingeleitete Längskraft entsprechend der sich einstellenden Hebelverhältnisse sowohl auf die obere Gelenkverbindung als auch die untere Gelenkverbindung.There are basically two different approaches possible. Thus, the axis of rotation can be arranged below a lower edge of the profile rail. Alternatively or additionally, however, it is also conceivable for the axis of rotation to be offset in the longitudinal direction of the profiled mounting rails in comparison to the separating area. In any case, the invention pursued offset of the axis of rotation ensures that acts on the profile rails longitudinal force acts on both the upper hinge connection and the lower hinge connection, if two such joints are realized, which is usually the case. Here, the initiated distributed Longitudinal force according to the adjusting leverage on both the upper joint and the lower joint.

Durch die spezielle Anordnung der Gelenkachse außerhalb des Trennbereiches wird erreicht, dass die besonders belastete untere Gelenkverbindung selbst bei einer Schrägstellung der Profillaufschienen im Stoßbereich zwischen benachbarten Profillaufschienen nicht ungewollt geöffnet wird. Außerdem werden durch die Verlagerung der Drehachse etwaige plastische Verformungen an der unteren Gelenkverbindung - selbst bei der beschriebenen Schrägstellung der Profillaufschienen - verhindert. Eine solche Schrägstellung der Profillaufschienen tritt in der Praxis durchaus auf und ist üblich, weil sich aufgrund von Bewegungen unter Tage auch der Ausbau zur Befestigung der Profillaufschienen bewegt und zu einem Versatz der Profillaufschienen gegeneinander führen kann.The special arrangement of the hinge axis outside of the separation area ensures that the particularly loaded lower hinge connection is not unintentionally opened even with an inclination of the profile rails in the joint area between adjacent profile rails. In addition, any plastic deformations on the lower hinge connection are prevented by the displacement of the axis of rotation - even in the described skewing of the profile rails. Such an inclination of profile rails occurs in practice quite well and is common because due to movements underground and the expansion moves to attach the profile rails and can lead to an offset of the profile rails against each other.

Jedenfalls sorgt die Verlagerung der Drehachse insbesondere unterhalb der Unterkante der Profillaufschiene dafür, dass an der Drehachse angreifende Längskräfte unmittelbar von der praktisch in gleicher Höhe angeordneten unteren Gelenkverbindung aufgenommen werden, ohne dass auf diese Gelenkverbindung Drehmomente der Gestalt wirken, dass diese unbeabsichtigt geöffnet wird. Vergleichbares gilt für den Fall, dass die Drehachse in Längsrichtung versetzt im Vergleich zum Trennbereich angeordnet ist. Hier hat sich meistens eine Anordnung an der Unterkante der jeweiligen Profillaufschiene als günstig erwiesen, wobei der Versatz in Längsrichtung im Vergleich zum Trennbereich bei einigen Millimetern, beispielsweise 5 mm oder 10 mm, angesiedelt ist. Vergleichbare Werte werden für den Versatz der Drehachse unterhalb der Unterkante der Profillaufschiene beobachtet.In any case, the displacement of the axis of rotation, in particular below the lower edge of the profiled rail, ensures that longitudinal forces acting on the axis of rotation are absorbed directly by the lower articulated joint arranged practically at the same height, without torques of the shape acting on this articulated joint that are unintentionally opened. The same applies to the case where the axis of rotation is offset in the longitudinal direction in comparison to the separation area. Here, an arrangement on the lower edge of the respective profiled mounting rail has proven to be favorable, wherein the offset in the longitudinal direction in comparison to the separation area at a few millimeters, for example 5 mm or 10 mm, is located. Comparable values are observed for the offset of the axis of rotation below the lower edge of the profile rail.

Bei der Ausgestaltung der unteren Gelenkverbindung hat es sich bewährt, wenn diese einen Schwenklagemocken mit Schwenklagerkopf aufweist, der in eine korrespondierende Schwenklagerkopfaufnahme einer Schwenklagertasche an der benachbarten Profilaufschiene eingreift. Meistens ist der Schwenklagernocken mit einem T-förmigen Schwenklagerkopf ausgerüstet. Folgerichtig verfügt auch die Schwenklagerkopfaufnahme im Regelfall über eine T-förmige Gestalt.In the design of the lower hinge connection, it has proven to be, if this has a Schwenklagemocken with pivot bearing head, in a corresponding Schwenklagerkopfaufnahme a Schwenklagerasche engages the adjacent Profilaufschiene. Mostly the pivot bearing cam is equipped with a T-shaped pivot bearing head. Consequently, the Schwenklagerkopfaufnahme usually has a T-shaped design.

Für die obere Gelenkverbindung empfiehlt die Erfindung, mit einem Schäkel zu arbeiten. Dabei kann es sich um einen Gabelschäkel oder auch um einen Y-Schäkel mit zwei Anschlusspunkten zur Festlegung an dem Ausbau handeln. In jedem Fall verbindet der jeweilige Schäkel jeweilige Lagerwangen am Oberflansch der benachbarten Profillaufschienen miteinander. Dabei sind die Lagerwangen in der Regel so ausgestaltet, dass sie jeweils den Stoßbereich bzw. Trennbereich zwischen benachbarten Profillaufschienen überbrücken.For the upper joint, the invention recommends to work with a shackle. This can be a fork shackle or a Y-shackle with two connection points to fix on the expansion. In any case, the respective shackle connects respective bearing cheeks to each other on the upper flange of the adjacent profile rails. The bearing cheeks are usually designed so that they each bridge the joint area or separation area between adjacent profile rails.

Im Ergebnis wird ein Schienenstrang zur Verfügung gestellt, der sich aus üblicherweise wenigstens zwei Profillaufschienen mit zugehöriger oberer und unterer Gelenkverbindung zusammensetzt. Dabei geht die Erfindung davon aus, dass sich Längskräfte von bis zu 140 kN dann problemlos übertragen lassen, wenn die Gelenkverbindung bzw. die untere Gelenkverbindung mit einem minimalen Querschnitt von wenigstens 6cm2 ausgerüstet ist. Denn in einem solchen Fall ist in Verbindung mit der oberen Gelenkverbindung eine wenigstens vierfache Sicherheit gegen Bruchversagen gegeben. Tatsächlich sorgt die Bemessung des minimalen Querschnittes von 6 cm2 i.V.m. der Verwendung eines Stahls mit einer Streckgrenze von wenigstens 300 N/mm2 dafür, dass die untere Gelenkverbindung allein Kräfte bis zur Streckgrenze von 180 kN aufnehmen kann. In Kombination mit der oberen Gelenkverbindung und unter Berücksichtigung der Tatsache, dass die obere Gelenkverbindung aufgrund der Hebelverhältnisse in etwa das Doppelte der Kräfte aufnimmt, ergibt sich die zuvor bereits angesprochene vierfache Sicherheit gegen Bruchversagen. Hierin sind die wesentlichen Vorteile zu sehen.As a result, a rail track is provided, which is usually composed of at least two profile rails with associated upper and lower hinge connection. The invention is based on the fact that longitudinal forces of up to 140 kN can be easily transferred if the articulated connection or the lower joint connection is equipped with a minimum cross section of at least 6 cm 2 . Because in such a case, at least fourfold security against breakage failure is given in connection with the upper joint. In fact, the design of the minimum cross-section of 6 cm 2 in conjunction with the use of a steel with a yield strength of at least 300 N / mm 2 ensures that the lower joint alone can absorb forces up to the yield strength of 180 kN. In combination with the upper hinge connection and taking into account the fact that the upper joint connection absorbs about twice the forces due to the lever ratios, the fourfold security already mentioned above against breakage results. Here are the main benefits.

In den Figuren ist ein Schienenstrang für Einschienen-Hängebahnen dargestellt, also ein solcher, der von einer Einschienen-Hängebahn mit Traglaufkatze und ggf. daran angeschlossenen Anhängern befahren wird. Das ist selbstverständlich nicht einschränkend zu verstehen. Jedenfalls setzt sich der Schienenstrang aus mehreren Profillaufschienen 1 zusammen, die im Ausführungsbeispiel durch zwei Gelenkverbindungen 2, 3 miteinander gekoppelt sind. Tatsächlich ist eine untere Gelenkverbindung 2 und ferner eine obere Gelenkverbindung 3 realisiert.In the figures, a rail track for monorail overhead conveyors is shown, ie one which is driven by a monorail overhead conveyor with trolley and possibly attached trailers. Of course, this is not meant to be limiting. In any case, the rail track is composed of several profile rails 1, which are coupled together in the embodiment by two joints 2, 3. In fact, a lower hinge 2 and further an upper hinge 3 is realized.

Die Profillaufschienen 1 verfügen über einen Oberflansch 4 und einen Laufflächen 6 für die Einschienenhängebahn aufweisenden Unterflansch 5.

The profile rails 1 have an I-shaped cross-section, so are designed according to the preceding explanations as E-rails.

Im Rahmen des Ausführungsführungsbeispiels und erfindungsgemäß verfügt die untere Gelenkverbindung 2 über einen in den Fig. 5 und 6 zu erkennenden minimalen Querschnitt Q, der wenigstens 6 cm2 groß ist. Tatsächlich wird im Rahmen des Ausführungsbeispiels nach Fig. 5 ein Querschnitt Q von ca. 9 cm2 beobachtet, wohingegen der Querschnitt im Rahmen der Variante nach Fig. 6 ca. 7 cm2 beträgt. Es versteht sich, dass die obere Gelenkverbindung 3 an dieser Stelle deutlich größere Querschnitte besitzt, weil sie im Allgemeinen bei auf die Profillaufschienen 1 wirkenden Längskräften wie durch Pfeile in der Fig. 1 angedeutet, einen Großteil dieser Längskräfte aufnimmt.In the context of the exemplary embodiment and according to the invention, the lower hinge 2 has a in the FIGS. 5 and 6 to be recognized minimum cross-section Q, which is at least 6 cm 2 in size. Indeed, within the scope of the embodiment Fig. 5 a cross-section Q of about 9 cm 2 observed, whereas the cross-section in the context of the variant Fig. 6 about 7 cm 2 . It is understood that the upper hinge joint 3 at this point has significantly larger cross-sections, because they generally acting on the profile rails 1 longitudinal forces as indicated by arrows in the Fig. 1 indicated, a majority of these longitudinal forces absorbs.

Nach einem selbstständigen Vorschlag der Erfindung definiert die untere Gelenkverbindung 2 eine Drehachse D für zugelassene Schwenkbewegungen zwischen den benachbarten Profillaufschienen 1, die außerhalb eines Trennbereiches oder Stoßbereiches T angesiedelt ist. Tatsächlich erstreckt sich dieser Trennbereich T zwischen den beiden benachbarten Profillaufschienen 1 und fällt insofern mit einem Stoßbereich zusammen. Dabei wird der Trennbereich T jeweils von der Unterkante des Unterflansches 5 und der Oberkante des Oberflansches 4 begrenzt, erstreckt sich also über die gesamte Länge des I-förmigen Profils der Profillaufschienen, und zwar in deren Spaltbereich.According to an independent proposal of the invention, the lower hinge joint 2 defines an axis of rotation D for permitted pivotal movements between the adjacent profile rails 1, which is located outside of a separation area or impact area T. In fact, this separation area T extends between the two adjacent profile rails 1 and thus coincides with a joint area. In this case, the separation region T is bounded in each case by the lower edge of the lower flange 5 and the upper edge of the upper flange 4, thus extending over the entire length of the I-shaped profile of the profile rails, in their gap region.

Erfindungsgemäß ist nun die von den beiden Gelenkverbindungen 2, 3 insgesamt definierte Drehachse D für Schwenkbewegungen zwischen den benachbarten Profillaufschienen 1 - im Gegensatz zum Stand der Technik - nicht in diesem Trennbereich T angesiedelt, sondern vielmehr außerhalb hiervon. Man erkennt bei der Variante nach Fig. 1 und Fig. 5, dass die besagte Drehachse D über einen Längsversatz L im Vergleich zu dem Trennbereich T verfügt, welcher vorliegend im Bereich von ca. 5mm oder noch mehr angesiedelt sein mag. Im Rahmen der Variante nach Fig. 6 findet sich die Drehachse D unterhalb der Unterkante des Unterflansches 5 und besitzt an dieser Stelle einen Querversatz V, welcher üblicherweise ebenfalls im Millimeterbereich angesiedelt ist. Selbstverständlich können der Längsversatz L wie der Querversatz V für die Drehachse D im Vergleich zum Trennbereich T auch miteinander kombiniert werden. In jedem Fall wird durch diese spezielle Lage der Drehachse D sichergestellt, dass die untere Gelenkverbindung 2 bei auftretenden Längskräften nicht unbeabsichtigt geöffnet und/oder hierbei verformt wird.According to the invention, the total of the two articulated joints 2, 3 defined pivot axis D for pivotal movements between the adjacent profile rails 1 - in contrast to the prior art - not located in this separation area T, but rather outside thereof. One recognizes the variant Fig. 1 and Fig. 5 in that the said axis of rotation D has a longitudinal offset L in comparison to the separating region T, which in the present case may be in the range of approximately 5 mm or even more. As part of the variant Fig. 6 is the axis of rotation D below the lower edge of the lower flange 5 and has at this point a transverse offset V, which is usually also settled in the millimeter range. Of course, the longitudinal offset L as the transverse offset V for the rotation axis D in comparison to the separation region T also be combined. In any case, it is ensured by this special position of the axis of rotation D, that the lower hinge joint 2 is not inadvertently opened and / or deformed during longitudinal forces occurring.

Tatsächlich wird nämlich zur Anbringung der Profillaufschienen 1 an einem Ausbau zunächst die obere Gelenkverbindung 3 hergestellt und festgelegt. Im Anschluss hieran wird die benachbarte Profillaufschiene 1 durch Verbinden der unteren Gelenkverbindung 2 an die benachbarte Profillaufschiene 1 angeschwenkt. Da die obere Gelenkverbindung 3 in der Regel über einen Schäkel 7 verfügt, welcher mit Lagerwangen 8 verschraubt, oder sonst wie verbunden ist, besteht insbesondere im Bereich der unteren Gelenkverbindung 2, die Gefahr, dass diese bei auftretenden Längskräften geöffnet wird und / oder sich verformt.In fact, for the attachment of the profiled rails 1 to a removal initially the upper hinge joint 3 is manufactured and fixed. Following this, the adjacent profile rail 1 is pivoted by connecting the lower joint 2 to the adjacent profile rail 1. Since the upper articulated connection 3 generally has a shackle 7 which is bolted to bearing cheeks 8, or otherwise connected, there is the danger, in particular in the area of the lower articulated connection 2, that this is opened when longitudinal forces occur and / or deforms ,

Beide Probleme werden erfindungsgemäß dadurch aufgefangen, dass die Drehachse D über den bereits beschriebenen Versatz L, V im Vergleich zum Trennbereich T verfügt, so dass an den Profillaufschienen 1 angreifende Längskräfte insbesondere die untere Gelenkverbindung 2 nahezu ausschließlich in Längsrichtung belasten, und zwar auch dann, wenn die Profillaufschienen 1 gegeneinander schräg gestellt sind, wie dies in den Fig. 1 und 2 angedeutet wird.Both problems are inventively absorbed by the fact that the axis of rotation D has the already described offset L, V in comparison to the separation region T, so that acting on the profile rails 1 longitudinal forces in particular load the lower hinge joint 2 almost exclusively in the longitudinal direction, even then, when the profile rails 1 are inclined against each other, as shown in the Fig. 1 and 2 is hinted at.

Dadurch, dass die in diesem Zusammenhang besonders belastete untere Gelenkverbindung 2 mit dem minimalen Querschnitt Q von wenigstens 6 cm2 ausgerüstet ist und in Übrigen die untere Gelenkverbindung 2 ebenso wie die obere Gelenkverbindung 3 aus einem Stahl mit einer Streckgrenze von wenigstens 300 N/mm2 hergestellt werden, lassen sich hierdurch insgesamt und problemlos Längskräfte von bis zu 140 kN aufnehmen. Das ist durch Pfeile in der Fig. 1 angedeutet.Because the lower articulated joint 2, which is particularly stressed in this connection, is equipped with the minimum cross-section Q of at least 6 cm 2 and, moreover, the lower articulated joint 2 as well as the upper articulated joint 3 are made of a steel with a yield strength of at least 300 N / mm 2 can be produced in this way and can absorb longitudinal forces of up to 140 kN. That's through arrows in the Fig. 1 indicated.

Im Detail verfügt die untere Gelenkverbindung 2 über einen Schwenklagemocken 2a mit einem T-förmigen Schwenklagerkopf 2b, der in eine korrespondierende Schwenklagerkopfaufnahme 2c einer Schwenklagertasche 2d an der benachbarten Profillaufschiene 1 angreift. Entsprechend der T-förmigen Gestalt des Schwenklagerkopfes 2b ist auch die Schwenklagerkopfaufnahme 2c T-förmig ausgeführt. Für die obere Gelenkverbindung empfiehlt die Erfindung den Rückgriff auf den bereits angesprochenen Schäkel 7, welcher im Rahmen der Fig. 1 als Gabelschäkel ausgeführt ist oder aber auch in Gestalt eines Y-Schäkels nach Fig. 2 vorliegend mag.In detail, the lower hinge 2 has a pivot cam 2 a with a T-shaped pivot bearing head 2 b, which engages in a corresponding pivot bearing head receptacle 2 c of a pivot bearing pocket 2 d on the adjacent profile rail 1. According to the T-shaped configuration of the pivot bearing head 2b, the pivot bearing head receptacle 2c is T-shaped. For the upper joint, the invention recommends recourse to the already mentioned shackle 7, which in the context of Fig. 1 designed as a fork shackle or in the shape of a Y-shackle after Fig. 2 in the present case.

In jedem Fall sorgt der besagte Schäkel 7 dafür, dass jeweilige Lagerwangen 8 an den benachbarten Profillaufschienen 1 im Bereich des Oberflansches 4 miteinander verbunden werden. Tatsächlich sind diese Lagerwangen 8 so ausgeführt, dass sie jeweils den Stoßbereich bzw. den Trennbereich T zwischen den benachbarten Profillaufschienen 1 überbrücken, wie insbesondere die Frontansicht der nach den Fig. 3 und 4 deutlich machen. Im Trennbereich T werden die diesen überbrückenden Lagerwangen 8 durch den Schäkel 7 miteinander verbunden.In any case, the said shackle 7 ensures that respective bearing cheeks 8 are connected to each other at the adjacent profile rails 1 in the region of the upper flange 4. In fact, these bearing cheeks 8 are designed such that they respectively bridge the joint area or the separation area T between the adjacent profile rails 1, in particular the front view of FIGS 3 and 4 make clear. In the separation region T, these bridging bearing cheeks 8 are connected to each other by the shackle 7.
