Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Halterung von Führungsschienen für Personen- und Lastenaufzüge nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for holding guide rails for passenger and goods lifts according to the preamble of claim 1.

Vorrichtungen zur Halterung von Führungsschienen für Personen- und Lastenaufzüge dienen insbesondere dazu, die Führungsschiene sicher zu halten. Diese haben die einschlägigen Normen für Aufzüge zu erfüllen, die auch dazu dienen, die Verformung der Führungsschiene während des Aufzugbetriebes zu begrenzen, damit der Fahrkorb eines Aufzuges oder das Gegengewicht ihre Fahrbahnen nicht verlassen können und sicherstellen, dass vorhandene Sicherheitseinrichtungen wie beispielsweise Fangvorrichtungen für ihre Funktion erfüllen können.Devices for holding guide rails for passenger and goods lifts serve in particular to hold the guide rail securely. These have to meet the relevant standards for lifts, which also serve to limit the deformation of the guide rail during elevator operation so that the elevator car or the counterweight cannot leave its lanes and ensure that existing safety devices such as safety devices for their function able to fulfill.

Insbesondere bei Überfahren eines Schienenstoßes einer Führungsschiene kann es jedoch zu einer nicht unerheblichen Geräuschentwicklung kommen. Durch eine Vorrichtung der eingangs genannten Art soll dieser Geräuschentwicklung durch die Zwischenlage eines schalldämmenden Isolators, der aus einem elastischen Kunststoff wie z.B. Polyurethan (Elastomer) oder aus einem Gummi bestehen kann, entgegengewirkt werden. Bei den bekannten Systemen ist nachteilig, dass nach den einschlägigen Sicherheitsüberlegungen für eine solche sandwichartig gestaltete Führungsschienenbefestigung die notwendigen Befestigungsschrauben, die zur Festlegung der Vorrichtung an einer Schachtwandung dienen, regelmäßig auf das richtige Anzugsmoment an der Wand kontrolliert werden müssen. Das schafft einen erheblichen Wartungsaufwand bei betriebenen Aufzuganlagen, da in aller Regel pro Vorrichtung zwei Befestigungsschrauben und entsprechende Halterungen einer Führungsschiene im Zweimeterabstand innerhalb eines Aufzugschachtes vorzusehen sind. Die Notwendigkeit der Kontrolle des Anzugmomentes der Schrauben ist insbesondere dadurch begründet, dass der Werkstoff des Isolators, wie beispielsweise ein Elastomer oder Gummi, ein auch durch Alterung und Setzerscheinungen begründetes Ausdehnungsverhalten hat, was sich auf das Anzugsmoment der Schraube negativ auswirken kann.Particularly when driving over a rail joint of a guide rail, however, a not inconsiderable noise development can occur. By means of a device of the type mentioned at the outset, this noise development is to be counteracted by the interposition of a sound-absorbing insulator, which can be made of an elastic plastic such as polyurethane (elastomer) or a rubber. In the known systems, it is disadvantageous that according to the relevant safety considerations for such a sandwich-like guide rail fastening, the necessary fastening screws, which serve to fix the device on a shaft wall, must be checked regularly for the correct tightening torque on the wall. This creates a considerable maintenance outlay for operated elevator systems, since it is generally per device Two fastening screws and corresponding brackets for a guide rail must be provided within two meters of an elevator shaft. The need to check the tightening torque of the screws is particularly due to the fact that the material of the insulator, such as an elastomer or rubber, has an expansion behavior that is also due to aging and signs of settling, which can have a negative effect on the tightening torque of the screw.

Aus der Schrift NL 7 712 756 A ist eine gattungsgemäße Vorrichtung bekannt. In dieser Schrift ist jedoch nicht näher dargelegt, wie der Wartungsaufwand für Aufzuganlagen begrenzt werden kann. Auch den Schriften EP 1 491 483 , JP 11 255449 , JP 2002 338168 A und DE 88 04 884 lässt sich keine konkrete diesbezügliche Lehre entnehmen.From Scripture NL 7 712 756 A a generic device is known. However, this document does not specify how the maintenance effort for elevator systems can be limited. The scriptures too EP 1 491 483 . JP 11 255449 . JP 2002 338168 A and DE 88 04 884 there is no concrete teaching in this regard.

Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Halterung von Führungsschienen für Personen und Lastenaufzüge zu schaffen, die weiterhin mit einem Körperschallisolator auszurüsten ist, bei der jedoch die Notwendigkeit entfällt, die Anzugsmomente von Befestigungsschrauben in regelmäßigen kurzen Wartungsintervallen zu überprüfen.It is an object of the present invention to provide a device for holding guide rails for people and goods lifts, which must also be equipped with a structure-borne sound insulator, but which does not need to check the tightening torques of fastening screws at regular, short maintenance intervals.

Zur Lösung dieser Aufgabe zeichnet sich die Vorrichtung zur Halterung von Führungsschienen für Personen- und Lastenaufzügen der eingangs genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 aus.To solve this problem, the device for holding guide rails for passenger and goods lifts of the type mentioned is characterized by the characterizing features of claim 1.

Wenn die Durchbiegung der Führungsschienen in einem maximal zulässigen Bereich gehalten werden muss und wenn man davon ausgeht, dass die Spalte im Laufe der Zeit durch Ausdehnungsbewegungen des Isolators ausgefüllt werden könnten, können die Sicherheitsnormen eingehalten werden, wenn die Spaltmaße unter Berücksichtigung der tatsächlichen Durchbiegung der Führungsschiene wie beschrieben dimensioniert werden.If the deflection of the guide rails must be kept within a maximum permissible range and if it is assumed that the gaps could be filled over time by expansion movements of the insulator, the safety standards can be met if the gap dimensions take into account the actual deflection of the guide rail be dimensioned as described.

Bei sehr kleinen Betriebskräften auf die Führungsschienen kann auf eine Vorspannung der Elastomer-Zwischenlage noch verzichtet werden. Sobald jedoch größere Betriebskräfte auf die Führungsschiene wirken, ist aufgrund des vorgesehenen Spaltmaßes sicherzustellen, dass eine Elastomer-Zwischenlage als Körperschallisolator aufgrund ihrer Nachgiebigkeit beim Anziehen von Befestigungsschrauben vorzuspannen ist. Kommen Alterungs- und Setzvorgänge dazu, greifen die Anschläge als Widerlager und begrenzen die Summe von Verformungen von Schienenbefestigung und Schiene. Als Anschläge kommen in baulicher Hinsicht verschiedene Widerlager in Betracht. So können diese Anschläge an der Befestigungskonsole, aber auch z.B. an Schachtwänden so vorgesehen sein, dass sie unter Ausbildung des Spaltmaßes Ausdehnungsbewegungen in der entsprechenden Ebene begrenzen. Ebenfalls ist es möglich, sei es alternativ oder kumulativ, Anschläge als Widerlager an dem Gegenprofil auszubilden. Es ist möglich, die Anschläge einstellbar auszubilden, indem diese beispielsweise durch Anschlagschrauben gebildet sind, die auf ein bestimmtes Spaltmaß eingestellt werden können.In the case of very small operating forces on the guide rails, there is no need to preload the elastomer intermediate layer. However, as soon as larger operating forces act on the guide rail, it must be ensured due to the gap dimension provided that an elastomer intermediate layer as a structure-borne sound insulator is to be preloaded due to its flexibility when tightening fastening screws. If aging and setting processes are added, the stops act as abutments and limit the total deformation of the rail fastening and rail. In terms of construction, various abutments can be considered as stops. Thus, these stops on the fastening bracket, but also, for example, on shaft walls, can be provided in such a way that they limit expansion movements in the corresponding plane while forming the gap dimension. It is also possible, alternatively or cumulatively, to design stops as abutments on the counter profile. It is possible to make the stops adjustable by, for example, forming stop screws that can be set to a certain gap size.

Durch eine einstellbare Anschlagschraube kann der Spalt auf ein gewünschtes individuelles Maß eingestellt werden. Dies ist vorteilhaft, wenn beispielsweise unterschiedliche dicke Isolatoren Verwendung finden und der Spalt unterschiedliche, den jeweiligen Isolatormaßen angepasste Maße aufweisen soll.The gap can be adjusted to a desired individual size using an adjustable stop screw. This is advantageous if, for example, different thick insulators are used and the gap should have different dimensions adapted to the respective insulator dimensions.

Nach einer Ausgestaltung der Erfindung wird der Isolator zumindest bereichsweise vorderseitig und seitlich von der Befestigungskonsole begrenzt. Schon durch die umfassende bereichsweise Begrenzung werden die Bewegungsfreiräume der Führungsschiene, welche durch den setzungsbedingten und den alterungsbedingten Schwund der Isolatordicke entstehen, so weit vermindert, dass die Kontrollintervalle für den korrekten Sitz der Schrauben erheblich verlängert werden können oder die Kontrollen ganz entfallen. Da die Schrauben ihre Befestigungsfunktion insbesondere durch eine Klemmkraft in Schraubrichtung erfüllen, ist eine Beschränkung des Schwundverhaltens in Richtung der Längsachse der Schraube vorteilhaft.According to one embodiment of the invention, the insulator is delimited at least in some areas on the front and on the side by the fastening bracket. The extensive area-by-area limitation reduces the freedom of movement of the guide rail, which is caused by the shrinking of the insulator thickness due to settlement and aging, to such an extent that the inspection intervals for the correct seating of the screws can be extended considerably or the controls are completely eliminated. Since the screws fulfill their fastening function in particular by a clamping force in the screwing direction, a limitation of the shrinkage behavior in the direction of the longitudinal axis of the screw is advantageous.

Nach einer Ausgestaltung der Erfindung ist die Befestigungskonsole zumindest im Bereich ihrer Anlage an dem Isolator im Querschnitt im Wesentlichen U-förmig mit abgewinkelten Seitenschenkeln ausgebildet. Dadurch kann das Bauteil einfach und kostengünstig bei guter Funktion gehalten werden.According to one embodiment of the invention, the fastening bracket is essentially U-shaped in cross section, at least in the region of its abutment on the insulator, with angled side legs. As a result, the component can be kept simple and inexpensive with good functionality.

Nach einer Ausgestaltung der Erfindung umgrenzt das Gegenprofil den Isolator und bereichsweise die Befestigungskonsole unter Ausbildung eines Spaltes. Durch die Umgrenzung ergibt sich eine doppelte Umgrenzung, aus der sich eine erhöhte Sicherheit ergibt.According to one embodiment of the invention, the counter profile delimits the insulator and, in some areas, the fastening bracket, forming a gap. The boundary results in a double boundary, which results in increased security.

Nach einer Ausgestaltung der Erfindung ist das Gegenprofil im Querschnitt U-förmig ausgebildet. Die U-Profile sind stabil und kostengünstig, die Anschläge erstrecken sich über die gesamte Profillänge und begrenzen so zuverlässig die mögliche Ausdehnung des Isolators.According to one embodiment of the invention, the counter profile is U-shaped in cross section. The U-profiles are stable and inexpensive, the stops extend over the entire profile length and thus reliably limit the possible expansion of the insulator.

Nach einer Ausgestaltung der Erfindung ist ein Widerlager für den Isolator an der Schachtwandung festgelegt. Eine schachtwandungsseitige Begrenzung des Isolators kann sich auf der Schachtwandung abstützen, die in der Regel unnachgiebig ist und die deshalb besonders hohe Widerstandskräfte aufzubauen vermag, ohne dass dafür ein besonders hoher Bauaufwand für das Begrenzungsbauteil getrieben werden müsste.According to one embodiment of the invention, an abutment for the insulator is fixed to the shaft wall. A boundary of the insulator on the shaft wall side can be supported on the shaft wall, which is generally unyielding and which is therefore able to build up particularly high resistance forces without having to drive a particularly high construction effort for the boundary component.

Nach einer Ausgestaltung der Erfindung sind Anschläge im Bereich einer Befestigungsschraube für die Vorrichtung vorgesehen. Da eine Befestigungsschraube immer benötigt wird, um die Befestigungskonsole mit der Schachtwandung zu verbinden, und eine Befestigungsschraube einen Isolator eher im mittigen Flächenbereich als im Randbereich durchgreift, kann von der Befestigungsschraube ausgehend ein größerer Flächenbereich des Isolators gegen unerwünschte Volumenveränderungen gesperrt werden.According to one embodiment of the invention, stops are provided in the area of a fastening screw for the device. Since a fastening screw is always required to connect the fastening bracket to the shaft wall, and a fastening screw penetrates an insulator in the central area rather than in the edge area, a larger area of the insulator can be blocked from the fastening screw against unwanted volume changes.

Nach einer Ausgestaltung der Erfindung ist unter einer Mutter zur Befestigungsschraube an einer Schachtwandung eine Feder oder ein Federpaket vorgesehen mit einer Federkennlinie, die weicher eingestellt ist als das Material des Isolators. Durch die Verwendung einer Feder oder eines Federpaketes können die auf den Isolator wirkenden Spannkräfte exakt eingestellt werden. Weiterhin bleibt eine Vorspannkraft auf der Schraube sicher erhalten.According to one embodiment of the invention, a spring or a spring assembly with a spring characteristic that is set softer than the material of the insulator is provided under a nut for the fastening screw on a shaft wall. By the use of a spring or a spring assembly allows the clamping forces acting on the insulator to be set precisely. Furthermore, a prestressing force on the screw is safely maintained.

Nach einer Ausgestaltung der Erfindung durchsetzt eine Befestigungsschraube die Befestigungskonsole, den Isolator und das Gegenprofil durch eine Kunststoffbuchse mit einem an der Befestigungskonsole anliegenden Buchsenkragen aus einem Kunststoffmaterial hindurch, wobei eine Ausdehnung der Kunststoffbuchse durch einen Anschlag als Widerlager für die Kunststoffbuchse begrenzt ist. Durch die Kunststoffbuchse können Schallschwingungen zusätzlich gedämpft werden. Da das Kunststoffmaterial der Kunststoffbuchse ebenfalls einem Volumenschwund unterliegen kann, ist es vorteilhaft, dieses ebenfalls durch Widerlager zu begrenzen.According to one embodiment of the invention, a fastening screw passes through the fastening bracket, the insulator and the counter-profile through a plastic bushing with a bushing collar made of a plastics material and resting against the fastening console, an expansion of the plastics bushing being limited by a stop as an abutment for the plastics bushing. The plastic bushing can also dampen sound vibrations. Since the plastic material of the plastic bushing can also be subject to volume shrinkage, it is advantageous to also limit this by means of abutments.

Nach einer Ausgestaltung der Erfindung ist ein Teil der Befestigungskonsole, die insbesondere mehrteilig ausgebildet sein kann und dann beispielsweise aus zwei gegensinnig abgewinkelten L-Winkeln besteht, die an einander zugewandten Schenkeln miteinander verschraubt werden, bereichsweise abgewinkelt nach Art eines U gestaltet, und das Gegenprofil, das ebenfalls den Isolator einfasst, hat die Gestalt eines U, wobei das U des Gegenprofils sowohl den U-förmigen Teil der Befestigungskonsole als auch den dazwischen gelegenen Isolator sowohl seitlich als auch zur Führungsschiene hin im montierten Zustand mit einem Spaltmaß umschließt.According to one embodiment of the invention, a part of the fastening bracket, which can in particular be made up of several parts and then consists, for example, of two L-angles angled in opposite directions, which are screwed together on mutually facing legs, angled in regions in the manner of a U, and the counter profile, which also surrounds the insulator has the shape of a U, the U of the counter-profile enclosing both the U-shaped part of the fastening bracket and the insulator in between, both laterally and to the guide rail in the assembled state with a gap.

Es wird ausdrücklich darauf hingewiesen, dass die vorstehend beschriebenen Ausgestaltungen der Erfindung jeweils für sich, aber auch in einer beliebigen Kombination untereinander mit dem Gegenstand des Hauptanspruchs kombinierbar sind.It is expressly pointed out that the embodiments of the invention described above can be combined individually, but also in any combination with one another, with the subject matter of the main claim.

In der Zeichnung sind grundsätzlich gleichwirkende Teile mit übereinstimmenden Bezugsziffern versehen. Allgemein mit 1 ist die Vorrichtung zur Halterung einer Führungsschiene 2 in einem Halterungsprofil 3 einer Schachtwandung 4 eines nicht näher gezeigten Personen- oder Lastenaufzuges beziffert. In der Regel ist die Vorrichtung 1 über in dem Ausführungsbeispiel gezeigte Befestigungsschrauben 5 in dem Halterungsprofil 3 befestigt. Diese Befestigungsschrauben 5 sind herkömmlicher Art mit einem Schraubenkopf 5,1, der formschlüssig im montierten Zustand mit seinen abgewinkelten Kopfkragenbereichen in entsprechend kongruent ausgebildeten Bereichen der Halterungsschiene 3 gelegen ist.In the drawing, parts that have the same effect are generally provided with the same reference numbers. Generally with 1, the device for holding a guide rail 2 in a mounting profile 3 is not closer to a shaft wall 4 shown passenger or freight elevator. As a rule, the device 1 is fastened in the mounting profile 3 by means of fastening screws 5 shown in the exemplary embodiment. These fastening screws 5 are of a conventional type with a screw head 5, 1, which is positively located in the assembled state with its angled head collar regions in correspondingly congruent regions of the mounting rail 3.

In dem dargestellten Ausführungsbeispiel besteht die an der Führungsschiene 2 über zwei Klammerbefestigungen 6 befestigte Befestigungskonsole 7 aus zwei L-Profilen 7.1 und 7.2, die über Schrauben 7.3 miteinander verbunden sind. Der obere Teil 7.2 (Fig. 3) der Befestigungskonsole 7 ist unter Zwischenlage eines Isolators 8 und des Gegenprofils 9 mit der Schachtwandung 4 verbunden. Die Befestigungskonsole 7, den Isolator 8 und das Gegenprofil 9 durchsetzt eine Kunststoffbuchse 10 mit einem Kragen 10.1. Unter Zwischenlage einer Unterlegscheibe ist die Befestigungsschraube über Muttern 5.2 gesichert. Unterhalb der Muttern kann auch noch ein Federpaket mit beispielsweise einer Kennlinie vorgesehen sein, die weicher eingestellt ist als die Kennlinie des Isolators 8.In the illustrated embodiment, the fastening bracket 7 fastened to the guide rail 2 by means of two clamp fasteners 6 consists of two L-profiles 7.1 and 7.2, which are connected to one another by screws 7.3. The upper part 7.2 ( Fig. 3 ) the mounting bracket 7 is connected to the shaft wall 4 with the interposition of an insulator 8 and the counter profile 9. The mounting bracket 7, the insulator 8 and the counter profile 9 passes through a plastic bushing 10 with a collar 10.1. With the interposition of a washer, the fastening screw is secured with nuts 5.2. A spring assembly with, for example, a characteristic curve, which is set softer than the characteristic curve of the isolator 8, can also be provided below the nuts.

Wie näher aus den ein erstes Ausführungsbeispiel illustrierenden Fig. 1 und 2 hervorgeht, sind Anschläge 9.1 und 9.2 an dem Gegenprofil 9 vorgesehen, die das Befestigungskonsolenteil 7-2 derart begrenzen, dass zwischen einem den Isolator 8 einfassenden Schenkel der Befestigungskonsole 7.2 und dem Seitenschenkel des Gegenstückes 9 Spalte 11 und 12 ausgebildet sind. Über den jeweiligen Spalt ist sichergestellt, dass der Isolator 8 zwar zu verformen ist, dass jedoch die Verformungen in Richtung auf die Wand zu und von der Schachtwandung weg, und zwar sowohl im oberen als auch im unteren Bereich sowie auch im linken und rechten Bereich, begrenzt und abgesichert sind. In dem gezeigten Ausführungsbeispiel ist durch jeweilige Abwinkelungen sowohl des Befestigungskonsolenteils 7.2 als auch des Gegenprofils 9 der Anschlag als starres Bauteil vorgesehen. Es ist jedoch auch möglich, z.B. Anschlagschrauben vorzusehen, so dass die Anschläge einstellbar auszubilden sind. Alternativ neben der gezeigten Lösung, bei denen der Anschlag an der Vorrichtung selbst vorgesehen ist, ist es auch möglich, einen entsprechenden Anschlag an der Wand anzubringen.As in more detail from those illustrating a first embodiment 1 and 2 shows stops 9.1 and 9.2 are provided on the counter profile 9, which limit the mounting bracket part 7-2 in such a way that gaps 11 and 12 are formed between a leg of the mounting bracket 7.2 enclosing the insulator 8 and the side leg of the counterpart 9. The respective gap ensures that the insulator 8 is to be deformed, but that the deformations towards the wall towards and away from the shaft wall, both in the upper and in the lower area as well as in the left and right area, are limited and secured. In the exemplary embodiment shown, the stop is provided as a rigid component by means of respective bends both of the fastening bracket part 7.2 and of the counter profile 9. However, it is also possible to provide stop screws, for example, so that the stops are adjustable. As an alternative to the solution shown, in which the stop is provided on the device itself, it is also possible to mount a corresponding stop on the wall.

In den Fig. 4 - 6 ist eine alternative Ausgestaltung der erfindungsgemäßen Vorrichtung 1 gezeigt Die Befestigungskonsole 7 weist in diesem Ausführungsbeispiel eine Platte 12 auf, die über gekonterte Schraubmuttern 13 mit zwei Schraubbolzen 15 fest verschraubt ist. Über zwei Klammerbefestigungen 6 ist die Platte 12 mit einer Führungsschiene 2 verbunden. Die von der Platte 12 entfernten Enden der Schraubbolzen 15 münden in einer Auflageplatte 14, die mit den Befestigungsschrauben 5 verbunden ist. Die Befestigungskonsole 7 wird so von der Platte 12, den Schraubbolzen 15 und der Auflageplatte 14 gebildet. Die Auflageplatte 14 begrenzt mit ihrer zum Isolator 8 gewandten Oberfläche den Ausdehnungsraum für den Isolator 8. Die Verbindung der Auflageplatte 14 zu den Befestigungsschrauben 5 wird über Halteklammern 16 hergestellt, die mit Vorsprüngen 17 die Auflageplatte 14 übergreifen. Zwischen den Halteklammern 16 und dem Isolator 8 befindet sich ein Spalt 11, der als ein begrenzter Expansionsraum für den Isolator 8 zur Verfügung steht.In the 4 - 6 An alternative embodiment of the device 1 according to the invention is shown. In this exemplary embodiment, the fastening bracket 7 has a plate 12 which is firmly screwed to two screw bolts 15 by means of locked screw nuts 13. The plate 12 is connected to a guide rail 2 via two clamp attachments 6. The ends of the bolts 15 removed from the plate 12 open into a support plate 14 which is connected to the fastening screws 5. The mounting bracket 7 is formed by the plate 12, the screw 15 and the support plate 14. The support plate 14 delimits the expansion space for the insulator 8 with its surface facing the insulator 8. The connection of the support plate 14 to the fastening screws 5 is established via holding clips 16 which overlap the support plate 14 with projections 17. There is a gap 11 between the holding clips 16 and the insulator 8, which is available as a limited expansion space for the insulator 8.

In den Figuren 7 - 9 ist ein drittes Ausführungsbeispiel gezeigt. Während Fig. 7 die Vorrichtung 1 aus einer Ansicht von schräg oben zeigt, ist Fig. 8 eine Schnittansicht von der Seite und Fig. 9 eine Ansicht von oben. Wie im Ausführungsbeispiel gemäß Fig. 4 - 6 weist auch hier die Befestigungskonsole 7 eine Platte 12 auf, die über gekonterte Schraubmuttern 13 mit zwei Schraubbofzen 15 fest verbunden ist. Abweichend vom Ausführungsbeispiel in den Fig. 4 - 6 sind die Schraubbolzen 15 jedoch nicht mit einer Auflageplatte 14 verbunden, sondern mit einer Einsteckplatte 18, die im Ausführungsbeispiel geteilt ausgeführt ist, so dass jeder Schraubbolzen 15 mit einer Einsteckplatte 18 verbunden ist. Die beiden Einsteckplatten 18 sind durch im Gegenprofil 9 befindliche Schlitze 19 hindurchgesteckt, so dass diese in den von seitlichen Schenkeln des Gegenprofils 9 begrenzten Innenraum des Gegenprofils 9 hineinragen. Im von seitlichen Schenkeln des Gegenprofils 9 begrenzten Innenraum ist der Isolator 8 angeordnet. Die Befestigungsschrauben 5 durchsetzen jeweils das Gegenprofil 9, den Isolator 8, die Einsteckplatte 18 und die Abdeckplatte 20, die allesamt durch die Verschraubung aufeinander gepresst gehalten sind. Das Gegenprofil 9 mit seinen seitlich zu einem U-förmigen Querschnitt aufgebogenen Schenkeln und die Abdeckplatte 20 bilden eine Art Käfig, in dem der Isolator 8 eingebettet ist. Zu den seitlichen Schenkeln des Gegenprofils 9 können wieder Spalte ausgebildet sein, in die sich der Isolator 8 begrenzt ausdehnen kann.In the Figures 7-9 a third embodiment is shown. While Fig. 7 shows the device 1 from a view obliquely from above Fig. 8 a sectional view from the side and Fig. 9 a top view. As in the exemplary embodiment according to 4 - 6 here, too, the mounting bracket 7 has a plate 12 which is firmly connected to two screw bosses 15 via countered screw nuts 13. Deviating from the embodiment in the 4 - 6 However, the bolts 15 are not connected to a support plate 14, but rather to an insert plate 18, which in the exemplary embodiment is designed to be divided, so that each bolt 15 is connected to an insert plate 18. The two insert plates 18 are inserted through slots 19 in the counter profile 9, so that they protrude into the interior of the counter profile 9 delimited by lateral legs of the counter profile 9. The insulator 8 is arranged in the interior delimited by lateral legs of the counter profile 9. The fastening screws 5 each pass through the counter profile 9, the insulator 8, the insert plate 18 and the cover plate 20, all of which are held pressed together by the screw connection. The counter profile 9 with its legs bent open laterally to form a U-shaped cross section and the cover plate 20 form a type of cage in which the insulator 8 is embedded. Gaps can again be formed in the lateral legs of the counter profile 9, into which the insulator 8 can expand to a limited extent.
