Description

Die Erfindung betrifft eine Aufhängung für eine mit einer Tragkonstruktion zu verbindende Schiene, insbesondere für eine Schiene einer Einschienenbahn, wobei diese Aufhängung einen Tragkörper aufweist, der einerseits mit der Schiene und andererseits höheneinstellbar über mindestens eine Schraubenverbindung mit der Tragkonstruktion verbindbar ist.The invention relates to a suspension for a rail to be connected to a support structure, in particular for a rail of a monorail, said suspension having a support body which is connected on the one hand with the rail and on the other hand height adjustable via at least one screw connection to the support structure.

Eine solche Aufhängung ist beispielsweise aus der DE-C 32 40 104 bekannt. Diese bekannte Aufhängung weist einen in seiner Grundform etwa C-förmig ausgebildeten Tragkörper auf, der einen oberen und einen unteren Schenkel besitzt. An dem freien Ende des unteren Schenkels ist eine Aufnahme angeordnet, die die Schiene hält und mit dieser verschraubbar ist. Der obere Schenkel des Tragkörpers ist zu einer in Einbaulage im Wesentlichen horizontal verlaufenden plattenförmigen Konsole ausgebildet, in die vier paarweise sich gegenüberliegende Durchgangslöcher für vertikale Halteschrauben ausgebildet sind. Die Schraubenköpfe der Halteschrauben sind in entsprechend geformte Ausnehmungen einer Halteplatte mit Durchgangslöchern für den jeweiligen Schraubenschaft angeordnet. Diese Halteplatte wird über Klemmpratzen und entsprechende vertikal verlaufende Schrauben an den Unterflansch eines Doppel-T-Trägers einer Tragkonstruktion angeklemmt. Die Höheneinstellung für die Aufhängung erfolgt über die Schäfte der vertikalen Halteschrauben, da die Konsole entlang der Schrauben verschiebbar ist. Die jeweils benötigte Höhenposition wird fixiert durch Kontermuttern, die in einer entsprechend geeigneten Position am Schraubenschaft über und unter der Konsole miteinander verspannt werden. Diese bekannte Aufhängung ist vergleichsweise aufwendig konstruiert, ist aber sehr gut einstellbar. Nachteilig ist jedoch, dass die Halteschrauben im Betrieb nicht nur auf Zug, sondern auch auf Biegung beansprucht werden.Such a suspension is for example from the DE-C 32 40 104 known. This known suspension has a in its basic form approximately C-shaped support body having an upper and a lower leg. At the free end of the lower leg, a receptacle is arranged, which holds the rail and can be screwed with this. The upper leg of the support body is formed into a substantially horizontally extending in the installed position plate-shaped bracket, are formed in the four pairs of opposite through holes for vertical retaining screws. The screw heads of the retaining screws are arranged in correspondingly shaped recesses of a retaining plate with through holes for the respective screw shaft. This retaining plate is clamped by means of clamping claws and corresponding vertically extending screws to the lower flange of a double-T-beam of a supporting structure. The height adjustment for the suspension via the shafts of the vertical retaining screws, since the console is displaceable along the screws. The required height position is fixed by lock nuts, which are clamped together in a suitable position on the screw shaft above and below the console. This known suspension is constructed comparatively expensive, but is very easy to adjust. The disadvantage, however, is that the Retaining screws are stressed in operation not only on train, but also on bending.

Ferner ist es aus der betrieblichen Praxis bekannt, die Höheneinstellung für die Aufhängung unter Verwendung sog. Futterplatten oder -bleche vorzunehmen, die ähnlich wie Unterleg- oder Distanzscheiben die Überbrückung eines Abstands zwischen zwei zu befestigenden Teilen gestatten. Diese Futterplatten werden im Bereich der Halteschraube zwischen dem Tragkörper und der Unterseite der Tragkonstruktion eingeklemmt. Je nach der Größe des einzustellenden Abstandes werden ein oder mehrere ggf. unterschiedlich dicke Futterplatten verwendet. Diese Lösung hat den Nachteil, dass sie im Hinblick auf den Materialverbrauch vergleichsweise aufwendig ist und darüber hinaus bei der Montage auch erhebliche Unfallgefahren in sich birgt, weil durch unbeabsichtigt herunterfallende Futterplatten ein erhebliches Gefährdungspotential für das im Bodenbereich z.B. einer Halle, in der eine hoch angeordnete Schienenanlage montiert wird, tätige Montagepersonal gegeben ist. Um die Futterbleche leicht montieren zu können, sind diese vielfach nämlich nicht mit einfachen Durchgangsbohrungen für die Schraubenverbindung versehen, sondern sind als geschlitzte Bleche ausgeführt, also mit Langlöchern versehen, die zum Blechrand hin offen sind; dadurch ist es nicht notwendig, eine bereits montierte Schraubenverbindung vollständig wieder zu lösen, um eine zusätzliche Futterplatte oder eine mit anderer Dicke anbringen zu können; es ist lediglich eine entsprechende Lockerung der Schraubenverbindung erforderlich, um dann die Futterplatte in die Verbindung einschieben zu können.Furthermore, it is known from the field practice to make the height adjustment for the suspension using so-called. Fodder plates or sheets, which allow as well as washers or spacers bridging a distance between two parts to be fastened. These lining plates are clamped in the region of the retaining screw between the support body and the underside of the supporting structure. Depending on the size of the distance to be set one or more optionally different thickness lining plates are used. This solution has the disadvantage that it is comparatively expensive in terms of material consumption and, moreover, also involves considerable accident risks during assembly, since a considerable hazard potential for the ground area, which is due to unintentionally falling down feed plates, for example. a hall in which a highly arranged rail system is mounted, active assembly personnel is given. In order to mount the lining sheets easily, these are often not provided with simple through holes for the screw connection, but are designed as slotted sheets, so provided with slots that are open to the edge of the sheet; thereby it is not necessary to completely loosen an already assembled screw connection again in order to attach an additional lining plate or one with a different thickness can; it is only a corresponding relaxation of the screw connection required to then insert the lining plate into the compound can.

Aufgabe der vorliegenden Erfindung ist es, eine Aufhängung gemäß dem Gattungsbegriff des Patentanspruchs 1 dahingehend weiterzubilden, dass sie mit möglichst geringem Materialaufwand bei hoher Funktionssicherheit und möglichst geringem Montageaufwand eine gute Höheneinstellbarkeit für den Ausgleich von Bautoleranzen an der jeweiligen Tragkonstruktion, an der sie zu befestigen ist, gewährleistet.Object of the present invention is to develop a suspension according to the preamble of claim 1 to the effect that they with the lowest possible cost of materials with high reliability and the lowest possible installation effort a good height adjustment for the compensation of building tolerances on the respective support structure to which it is to be secured, guaranteed.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale. Vorteilhafte Weiterbildungen der Erfindung, deren Merkmale in beliebiger Weise miteinander kombiniert werden können, sind in den Unteransprüchen niedergelegt.This object is achieved according to the invention by the features stated in the characterizing part of patent claim 1. Advantageous developments of the invention, the features of which can be combined in any manner with one another, are laid down in the subclaims.

Wesentliches Kennzeichen der vorliegenden Erfindung ist es, dass die Höheneinstellbarkeit des Tragkörpers über eine als Langlochverbindung ausgeführte Schraubenverbindung erreicht wird, die im nicht angezogenen Zustand der Schraube die Verschieblichkeit der miteinander zu verbindenden Teile gewährleistet, aber im angezogenen Zustand die Vorzüge einer formschlüssigen Verbindung im Hinblick auf die im Betrieb auf die miteinander verbundenen Teile einwirkenden Belastungen aufweist. Dies wird dadurch erreicht, dass die durch die Langlochverbindung miteinander verbundenen Teile zumindest im Bereich ihrer Berührungsflächen eine komplementär zueinander profilierte Oberfläche aufweisen. Dies bedeutet, dass die Profilierungen des einen Teils in entsprechende Profilierungen des anderen Teils eingreifen, so dass im angezogenen Zustand der Schraubenverbindung eine körperliche Verhakung und somit eine feste Verankerung gegeben ist. Höhen in der Profilierung des einen Teils korrespondieren also mit entsprechenden Tiefen in der Profilierung des anderen Teils und umgekehrt. Die Profilierung ist in der Weise ausgeführt, dass eine Rasterung gegeben ist. Das bedeutet, dass die miteinander zu verbindenden Teile in unterschiedliche Positionen gegeneinander verschoben werden können und dennoch in diesen jeweiligen Positionen bei Bedarf durch die Schraubenverbindung zur komplementären festen Anlage aneinander gebracht werden können. Es versteht sich von selbst, dass die Profilierung nicht über die gesamte Berührungsfläche erstreckt sein muss, sondern auf Teilbereiche beschränkt sein kann. Die nicht profilierten Flächenanteile dürfen dabei natürlich nicht das Ineinandergreifen der Profilierungen verhindern. Weiterhin ist klar, dass die Langlochverbindung keine geschlossenen Langlöcher voraussetzt, sondern diese am Rand auch geöffnet sein können, um eine einfache Montage bei bereits zusammengefügter, aber noch nicht angezogener Schraubenverbindung zu ermöglichen.An essential feature of the present invention is that the height adjustability of the support body is achieved via a screw connection executed as a slot connection, which ensures the displaceability of the parts to be joined together in the non-tightened state of the screw, but in the tightened state the benefits of a positive connection with respect to having in operation on the interconnected parts acting loads. This is achieved in that the parts interconnected by the oblong connection have a surface profiled complementarily to each other at least in the area of their contact surfaces. This means that the profilings of one part engage in corresponding profilings of the other part, so that in the tightened state of the screw connection a physical entanglement and thus a firm anchoring is provided. Heights in the profiling of one part thus correspond with corresponding depths in the profiling of the other part and vice versa. The profiling is carried out in such a way that a screening is given. This means that the parts to be joined together can be shifted in different positions against each other and yet can be brought together in these respective positions if necessary by the screw connection to the complementary fixed abutment. It goes without saying that the profiling need not be extended over the entire contact surface, but on Subareas may be limited. Of course, the non-profiled surface portions must not prevent the interlocking of the profilings. Furthermore, it is clear that the slot connection does not require closed slots, but these can also be open at the edge to allow easy assembly with already assembled, but not yet tightened screw connection.

In Figur 1 ist die Zusammenstellung einer erfindungsgemäßen Aufhängung im Einzelnen dargestellt. Die Tragkonstruktion 10, an der die Schiene 11 einer Einschienenbahn aufgehängt werden soll, ist im vorliegenden Fall in Form eines Doppel-T-Trägers ausgeführt, wie insbesondere aus der korrespondierenden Vorderansicht der Aufhängung in Figur 2 dargestellt ist. Ein wesentlicher Teil der Aufhängung ist ein Tragkörper 1, der im Wesentlichen die Form eines "C" hat. Dieser Tragkörper ist vorzugsweise als durch Brennschneiden oder einen Laserschnitt aus einer Blechtafel ausgeschnittenes Bauteil ausgebildet. Seine Dicke liegt typischer Weise in einem Bereich von z.B. 8 bis 20 mm. Der Tragkörper 1 besitzt einen unteren Schenkel 6 und einen oberen Schenkel 7, die sich in Einbaulage jeweils etwa horizontal von dem im Übrigen vertikal verlaufenden restlichen Teil des "C" erstrecken. Dabei weist der untere C-Schenkel 6 eine deutlich kürzere Länge als der obere C-Schenkel 7 auf. Am freien Ende des unteren C-Schenkels 6 ist ein kurzes Anschlussprofil 14 angeschweißt, das z.B. in Form eines L-Profils ausgebildet ist und das im vorliegendem Fall zwei Löcher für Schraubenverbindungen 17 aufweist, mit denen die Schiene 11 mit dem unteren C-Schenkel verbunden werden kann. Der obere C-Schenkel 7 dient zur Befestigung mit der Tragkonstruktion 10. Diese Befestigung erfolgt nicht direkt, sondern über mindestens ein, im vorliegenden Fall zwei Halteprofilen, die z.B. als L-Profile 4 ausgebildet sind. Der Tragkörper 1 wird mittels mindestens einer Schraubenverbindung 2 (im vorliegenden Fall zwei Schraubenverbindungen) mit den beiden L-Profilen 4 verschraubt, so dass der obere C-Schenkel 7 symmetrisch zwischen den in Einbaulage vertikal gerichteten Schenkel 9 der beiden L-Profile 4 fest eingeklemmt ist. Der jeweilige horizontale Schenkel 12 der beiden L-Profile 4 dient zur Befestigung der L-Profile 4 an der Tragkonstruktion 10. Diese Schenkel 12 weisen hierzu mindestens ein, vorzugsweise mehrere (im dargestellten Fall zwei) Durchgangslöcher für eine Schraubenverbindung 16 auf. Jedem dieser Durchgangslöcher bzw. jeder Schraubenverbindung 16 ist eine Klemmpratze 15 zugeordnet, die sich einerseits auf der Oberseite des horizontalen Schenkels 12 des jeweiligen L-Profils 4 und andererseits auf dem Untergurt des Doppel-T-Trägers der Tragkonstruktion 10 abstützen kann. Somit sind die beiden L-Profile 4 bei angezogener Schraubenverbindung 16 fest an die Unterseite des Untergurts des Doppel-T-Trägers angepresst. Um eine Klemmung des Tragkörpers 1 in unterschiedlicher Höhenposition relativ zu den beiden L-Profilen 4 zu ermöglichen, sind die Durchgangslöcher für die beiden Schraubenverbindungen 2 am Tragkörper 1 nicht als kreisförmige Löcher, sondern als Langlöcher 3 ausgeführt, deren Längsachse in Einbaulage vertikal gerichtet ist. Selbstverständlich ist es auch möglich, mehr als zwei Schraubenverbindungen 2 vorzusehen. Im vorliegenden Fall sind die Langlöcher 3 geschlossen ausgeführt; sie könnten aber auch zum Rand des Tragkörpers hin offen sein. Die geschlossene Ausführung der Langlöcher 3 ist insbesondere aus Sicherheitsgründen zu bevorzugen. Grundsätzlich möglich wäre es auch, die Durchgangslöcher an den L-Profilen 4 als Langlöcher mit vertikaler Ausrichtung vorzusehen. Es könnten aber auch Langlöcher sowohl an den L-Profilen 4 als auch an dem Tragkörper 1 vorgesehen sein, um einen besonders großen Verstellbereich hinsichtlich der Höhenjustierung zu ermöglichen. Im Allgemeinen ist es jedoch völlig ausreichend und im Rahmen der vorliegenden Erfindung bevorzugt, die Langlöcher wie in Figur 3 dargestellt, nur an dem Tragkörper 1 anzubringen. Es versteht sich von selbst, dass die Durchgangslöcher an den L-Profilen 4 mit den Langlöchern 3 des Tragkörpers 1 korrespondieren müssen, also in der gewünschten Montagestellung aufeinander passen. Insofern müssen die Breite der Langlöcher 3 und deren Abstand untereinander auf den Durchmesser oder die Breite der anderen Durchgangslöcher und deren Abstand abgestimmt sein. Besonders wesentlich ist es, dass die Höhenposition des Tragkörpers 1, also dessen relative Lage gegenüber den vertikalen Schenkeln 9 der beiden L-Profile 4 nicht nur gut einstellbar, sondern darüber hinaus auch absolut sicher fixierbar ist. Hierzu sieht die Erfindung vor, die Verbindung zwischen diesen jeweils aneinander zu befestigenden Teilen im Bereich ihrer Berührungsflächen mit komplementär zueinander profilierten Oberflächen 5 zu versehen, wie sie in Figur 3 in der Seitenansicht des Tragkörpers 1 angedeutet und in der Figur 4 im Rahmen der vergrößert dargestellten Einzelheit Z erkennbar sind. Grundsätzlich sind für eine solche Profilierung beliebige Formen von Erhöhungen und miteinander korrespondierenden Vertiefungen geeignet, also beispielsweise kalottenförmige Ausbauchungen und entsprechende Einkerbungen, die einen festen Rasterabstand voneinander aufweisen, um unterschiedliche Höhenpositionen zu ermöglichen.In FIG. 1 the composition of a suspension according to the invention is shown in detail. The support structure 10 to which the rail 11 of a monorail is to be suspended is designed in the present case in the form of a double-T-beam, as in particular from the corresponding front view of the suspension in FIG. 2 is shown. An essential part of the suspension is a support body 1, which has substantially the shape of a "C". This support body is preferably formed as cut by flame cutting or a laser cut from a metal sheet component. Its thickness is typically in a range of eg 8 to 20 mm. The support body 1 has a lower leg 6 and an upper leg 7, which extend in the installed position in each case approximately horizontally from the rest of the otherwise vertically extending remaining part of the "C". In this case, the lower C-leg 6 has a significantly shorter length than the upper C-leg 7. At the free end of the lower C-leg 6, a short connection profile 14 is welded, which is formed for example in the form of an L-profile and in the present case has two holes for screw 17, with which the rail 11 is connected to the lower C-leg can be. The upper C-leg 7 is used for attachment to the support structure 10. This attachment is not directly, but at least one, in the present case, two retaining profiles, which are formed for example as L-profiles 4. The support body 1 is screwed by means of at least one screw 2 (in the present case, two screw) with the two L-profiles 4, so that the upper C-leg 7 symmetrically clamped between the vertical in the installed position leg 9 of the two L-profiles 4 is. The respective horizontal limb 12 of the two L-profiles 4 serves for fastening the L-profiles 4 to the support structure 10. For this purpose, these limbs 12 have at least one, preferably a plurality of through-holes for a screw connection 16 (in the illustrated case two). Each of these through holes or each screw connection 16 is associated with a clamping claw 15, which can be supported on the one hand on the top of the horizontal leg 12 of the respective L-profile 4 and on the other hand on the lower flange of the double-T-beam of the support structure 10. Thus, the two L-profiles 4 are firmly pressed with tightened screw 16 to the underside of the lower chord of the double-T-beam. To a clamping of the support body 1 in different height position relative to the two L-profiles 4 to allow the through holes for the two screw connections 2 on the support body 1 are not designed as circular holes, but as elongated holes 3, whose longitudinal axis is directed vertically in the installed position. Of course, it is also possible to provide more than two screw 2. In the present case, the slots 3 are executed closed; but they could also be open to the edge of the support body. The closed version of the elongated holes 3 is to be preferred in particular for safety reasons. In principle, it would also be possible to provide the through-holes on the L-profiles 4 as elongated holes with a vertical orientation. But it could also be provided slots on both the L-profiles 4 and on the support body 1 to allow a particularly large adjustment range in terms of height adjustment. In general, however, it is quite sufficient and preferred in the context of the present invention, the slots as in FIG. 3 shown, only to be attached to the support body 1. It goes without saying that the through holes must correspond to the L-profiles 4 with the slots 3 of the support body 1, so fit together in the desired mounting position. In this respect, the width of the elongated holes 3 and their spacing must be matched to each other on the diameter or the width of the other through holes and their distance. It is particularly important that the height position of the support body 1, so its relative position relative to the vertical legs 9 of the two L-profiles 4 not only well adjustable, but beyond that is also absolutely sure fixable. To this end, the invention provides for the connection between these parts to be fastened to each other in the region of their contact surfaces with surfaces 5 profiled in a complementary manner to one another, as they are described in US Pat FIG. 3 indicated in the side view of the support body 1 and in the FIG. 4 in the context of the detail Z shown enlarged are recognizable. Basically, for such profiling arbitrary forms of elevations and each other corresponding recesses suitable, so for example, dome-shaped bulges and corresponding notches, which have a fixed grid spacing from each other to allow different height positions.

Besonders zweckmäßig ist es, die Profilierung 5 der Oberflächen von Tragkörper 1 und den beiden L-Profilen 4 im Sinne einer Verzahnung 13a, 13b auszuführen, wie dies exemplarisch in Figur 4 für den Tragkörper 1 und in Figur 5 für ein L-Profil 4 dargestellt ist. Diese Verzahnung kann beispielsweise im Querschnitt die Form einer Wellenlinie aufweisen. Im dargestellten Ausführungsbeispiel sind die beiden Verzahnungen 13a, 13b jeweils im Querschnitt als einfache Zick-Zack-Linien ausgebildet. Wesentlich ist es, dass in Einbaulage die Zahnbreite der Verzahnung 13a, 13b im Wesentlichen in horizontaler Richtung verläuft, damit in vertikaler Richtung eine Rasterung gewährleistet ist. Das dargestellte Ausführungsbeispiel zeigt eine besonders einfache Verzahnung, bei der die Zacken der Zick-Zack-Linie jeweils gleichlange Schenkel aufweisen, die einen Spitzenwinkel α zwischen sich einschließen, der zweckmäßigerweise im Bereich von 80 bis 110° liegt und vorzugsweise etwa 90° beträgt. Die Wellenlänge w liegt zweckmäßig in einer Größenordnung von etwa 2 mm, was einer Rasterung der Höheneinstellung um jeweils Inkremente von 2 mm entspricht. Dies ist für die Genauigkeit der Höheneinstellung völlig ausreichend und ist auf der anderen Seite fertigungstechnisch sehr leicht herstellbar. Die Herstellung kann z.B. auf spanendem Wege oder aber auch spanlos durch Eindrücken bzw. Einwalzen einer entsprechenden Profilierung erfolgen. Wesentlich ist lediglich, dass die Profilierungen 13a, 13b miteinander korrespondieren, also in unterschiedlichen Höhenstellungen ineinander passen. In Figur 3 ist eine Sichtkante 18 eingezeichnet, die den Bereich der profilierten Oberfläche 5 nach unten begrenzt. Das in Figur 6 in der Draufsicht auf den horizontalen Schenkel 12 dargestellte L-Profil 4 weist zwei Langlöcher 19 auf, die nicht parallel, sondern schräg zueinander liegen. Durch diese Langlöcher 19 sind die Schraubenverbindungen 16 für die Klemmpratzen 15 geführt. Durch eine Verschiebung der Schraubenverbindungen 16 in den Langlöchern 19 lässt sich eine geeignete Anpassung an unterschiedlich große Doppel-T-Träger der Tragkonstruktion erzielen.It is particularly expedient to carry out the profiling 5 of the surfaces of the support body 1 and the two L-profiles 4 in the sense of a tooth system 13a, 13b, as shown by way of example in FIG FIG. 4 for the support body 1 and in FIG. 5 for an L-profile 4 is shown. This toothing may, for example, have the shape of a wavy line in cross section. In the illustrated embodiment, the two teeth 13a, 13b are each formed in cross-section as a simple zig-zag lines. It is essential that in the installation position, the tooth width of the teeth 13a, 13b extends substantially in the horizontal direction, so that a screening is ensured in the vertical direction. The illustrated embodiment shows a particularly simple toothing, in which the teeth of the zig-zag line each have the same length legs, which enclose a point angle α between them, which is suitably in the range of 80 to 110 ° and preferably about 90 °. The wavelength w is expedient in the order of about 2 mm, which corresponds to a screening of the height adjustment by increments of 2 mm. This is completely sufficient for the accuracy of the height adjustment and is on the other hand production technology very easy to produce. The preparation can be done, for example, by cutting or without cutting by impressions or rolling a corresponding profiling. It is only essential that the profilings 13a, 13b correspond to one another, that is, they fit into one another in different height positions. In FIG. 3 a visible edge 18 is located, which limits the area of the profiled surface 5 down. This in FIG. 6 in the plan view of the horizontal leg 12 illustrated L-profile 4 has two slots 19, the not parallel, but at an angle to each other. Through these slots 19, the screw connections 16 are guided for the clamping claws 15. By a displacement of the screw connections 16 in the oblong holes 19, a suitable adaptation to differently sized double T-beams of the supporting structure can be achieved.

Die erfindungsgemäße Ausbildung einer Schienenaufhängung beinhaltet nicht nur eine sehr geringe Zahl unterschiedlicher Einzelteile, sondern erfordert darüber hinaus auch nur sehr einfach gestaltete Bauteile wie Winkelprofile, Schrauben und ein ausgeschnittenes Blechelement von mehreren mm Dicke als Tragkörper. Besonders wesentlich ist es, dass eine äußerst einfache und schnelle Anpassung an die jeweils genötigte Höhenposition möglich ist. Diese wird durch die aufgeprägte Rasterung in den durch die Langlochverbindung 8 miteinander zu verbindenden Teilen ermöglicht. Die Rasterung gewährleistet eine äußerst schnelle provisorische Fixierung von Hand, die durch Anziehen der Schraubenverbindung 2 einfach fixiert werden kann und im Sinne eines Formschlusses gegenüber den austretenden Betriebsbelastungen absolut gesichert ist. Während der Justierungsarbeiten werden keinerlei zusätzliche ausgleichende Teile wie etwa Futterplatten benötigt, die dem Montagepersonal unbeabsichtigt aus der Hand entgleiten könnten und eine Verletzungsgefahr beinhalten würden. Somit liefert die Erfindung eine Aufhängung, die nicht nur kostengünstig herstellbar, sondern auch schnell, sicher und kostengünstig montierbar ist.The inventive design of a rail suspension not only includes a very small number of different items, but also requires only very simple design components such as angle profiles, screws and a cut sheet metal element of several mm thickness as a support body. It is particularly important that an extremely simple and quick adaptation to the respective required height position is possible. This is made possible by the impressed screening in the parts to be joined together by the slot connection 8. The grid ensures an extremely quick provisional fixation by hand, which can be easily fixed by tightening the screw 2 and is absolutely secured in terms of a positive connection to the exiting operating loads. During the adjustment work, no additional compensating parts such as lining plates are required, which could unintentionally slip out of the hand of the assembly personnel and involve a risk of injury. Thus, the invention provides a suspension that is not only inexpensive to produce, but also fast, safe and inexpensive to install.
