Description

Die Erfindung betrifft ein ankerförmiges Aufhängeteil für eine im Querschnitt im Wesentlichen C-förmige Tragschiene einer Unterdecke. Das ankerförmige Aufhängeteil umfasst einen Grundkörper mit einer Längsausdehnung in Richtung einer Mittenlängsachse, mit zwei bezogen auf die Richtung der Mittenlängsachse seitlichen Rändern, mit einem in Richtung der Mittenlängsachse betrachteten unteren Rand und mit einer Grundkörper-Hauptebene, wobei der Grundkörper zwei Ankeransätze hat, die jeweils an einem der seitlichen Ränder des Grundkörpers einstückig am Grundkörper angeformt sind, die zumindest im montierten Zustand nach oben ragen und die dazu ausgelegt sind, im montierten Zustand entsprechend nach innen abgewinkelte Schenkelenden der Tragschiene zu untergreifen. Die Richtungsangabe "nach oben" bezieht sich dabei insbesondere auf die Richtung der Mittenlängsachse.The invention relates to an anchor-shaped suspension part for a cross-sectionally substantially C-shaped mounting rail a ceiling. The armature-shaped suspension part comprises a main body with a longitudinal extent in the direction of a central longitudinal axis, with two lateral edges with respect to the direction of the central longitudinal axis, with a lower edge viewed in the direction of the central longitudinal axis and with a main body main plane, wherein the main body has two anchor shoulders, respectively are integrally formed on one of the lateral edges of the base body on the base body, which protrude at least in the mounted state upwards and which are adapted to engage in the assembled state according to inwardly angled leg ends of the mounting rail. The direction "upwards" refers in particular to the direction of the central longitudinal axis.

Ein derartiges Aufhängeteil ist beispielsweise aus der EP 1 394 331 B1 bekannt. Das dort offenbarte Aufhängeteil ist an dem unteren Ende des Grundkörpers mit einem Federelement ausgestattet, welches im montierten Zustand gegen den Boden der als CD-Profil ausgeführten Tragschiene drückt, so dass die Ankeransätze unter die abgewinkelten Schenkelenden der Tragschiene gedrückt werden. Das als gesonderte Komponente ausgeführte Federelement hat einen Befestigungs-Abschnitt, mittels dessen es an dem Grundkörper fixiert ist. Hierzu ist eine Niete vorgesehen. Dieses Aufhängeteil hat sich im praktischen Gebrauch bewährt. Allerdings besteht zumindest bei manchen Anwendungen Bedarf an einer leichteren Montierbarkeit und auch an einer besonders kostengünstigen Ausführung. Weiterhin wird in der JP H09 41544 A ein ankerförmiges Aufhängeteil gemäß dem Oberbegriff des Anspruchs 1 beschrieben, dessen Grundkörper ein am unteren Ende mittels eines Biegeabschnitts einstückig angeformtes abgewinkeltes Anpresselement umfasst. Dieses Anpresselement weist eine untere Anpresskante auf, die dazu ausgelegt ist, im montierten Zustand gegen einen Boden der Tragschiene zu drücken.Such a suspension part is for example from the EP 1 394 331 B1 known. The suspension part disclosed therein is equipped at the lower end of the base body with a spring element which presses in the assembled state against the bottom of the carrier rail designed as a CD profile, so that the anchor projections are pressed under the angled leg ends of the support rail. The designed as a separate component spring element has a mounting portion, by means of which it is fixed to the body. For this purpose, a rivet is provided. This suspension part has proven itself in practical use. However, there is at least in some applications the need for easier mounting and also a particularly cost-effective design. Furthermore, in the JP H09 41544 A An anchor-shaped suspension part according to the preamble of claim 1 described, the base body comprises an integrally formed at the lower end by means of a bent portion angled contact pressure. This pressing element has a lower contact edge, which is designed to press in the mounted state against a bottom of the support rail.

Die Aufgabe der Erfindung besteht deshalb darin, ein Aufhängeteil der eingangs bezeichneten Art mit gegenüber dem Stand der Technik verbesserten Eigenschaften anzugeben.The object of the invention is therefore to provide a suspension part of the type described above with improved over the prior art properties.

Zur Lösung dieser Aufgabe wird ein Aufhängeteil entsprechend den Merkmalen des Patentanspruchs 1 angegeben. Bei dem erfindungsgemäßen Aufhängeteil handelt es sich um ein solches, bei dem der Grundkörper ein mittels mindestens eines Biegeabschnitts einstückig angeformtes Anpresselement umfasst, das von einer aus der Grundkörper-Hauptebene heraus geschwenkten Montierstellung in eine Anpressstellung (oder insbesondere in eine Arretierstellung) insbesondere mittels Biegens verschwenkbar ist, wobei das Anpresselement sich in seiner Anpressstellung im Wesentlichen innerhalb der Grundkörper-Hauptebene befindet, und eine untere Anpresskante aufweist, die dazu ausgelegt ist, im montierten Zustand und bei in der Anpressstellung befindlichem Anpresselement gegen einen Boden der Tragschiene zu drücken. Das Anpresselement ist mittels zweier auf einander gegenüberliegenden Seiten des Anpresselements angeordneter Biegeabschnitte einstückig mit dem Grundkörper verbunden, und die zwei Biegeabschnitte definieren eine Schwenkachse, um die das Anpresselement verschwenkbar ist.To solve this problem, a suspension part according to the features of claim 1 is given. The suspension part according to the invention is one in which the base body comprises a pressing element integrally formed by at least one bending section, which can be pivoted from a mounting position pivoted out of the main body plane into a pressing position (or in particular into a locking position), in particular by means of bending is, wherein the pressing member is in its Anpressstellung substantially within the main body main plane, and having a lower contact edge, which is adapted to press in the assembled state and located in the Anpressstellung pressing member against a bottom of the support rail. The pressing element is integrally connected to the base body by means of two bending sections arranged on opposite sides of the pressing element, and the two bending sections define a pivot axis about which the pressing member is pivotable.

Es wurde erkannt, dass sich sowohl die Handhabung des Aufhängeteils während der Montage verbessern lässt als auch die Herstellungskosten reduzieren lassen, indem das Federelement der aus dem Stand der Technik bekannten Ausgestaltung gegen ein vorzugsweise einstückig mit dem Grundkörper ausgestaltetes und insbesondere zusätzlich auch verschwenkbares Anpresselement ausgetauscht wird.It has been recognized that both the handling of the suspension part during assembly can be improved and the manufacturing costs can be reduced by exchanging the spring element of the embodiment known from the prior art for a preferably integrally formed with the base body and in particular additionally pivotable contact pressure element ,

Zum einen entfällt dadurch ein gesondertes Bauteil, das eine Extra-Befestigung mit dem Grundkörper erfordert. Stattdessen ist das Anpresselement unmittelbar mit dem Grundkörper verbunden. Es ist insbesondere ein integraler Bestandteil des Grundkörpers. Dadurch sinken die Herstellungskosten. Insbesondere ist der Grundkörper inklusive des einstückig angeformten oder verbundenen Anpresselements aus einem Blech-Ausgangsmaterial geformt. Abgesehen von dem aus der Grundkörper-Hauptebene heraus schwenkbaren Anpresselement hat der Grundkörper insofern eine insbesondere im Wesentlichen plattenförmige oder flache Gestalt. Vorzugsweise gilt dies im Wesentlichen auch für das Anpresselement an sich. Gegebenenfalls können das Anpresselement und/oder der übrige Grundkörper Versteifungselemente aufweisen, die zu einer gewissen, aber nicht maßgeblichen Abweichung von der reinen Plattenform führen.On the one hand eliminates a separate component that requires an extra attachment to the body. Instead, the pressing element is connected directly to the base body. It is especially an integral part of the body. This reduces the production costs. In particular, the base body including the integrally formed or connected pressing element is formed from a sheet metal starting material. Apart from the pressing element which can be pivoted out of the basic body plane, the base body has a particularly substantially plate-shaped or flat shape. Preferably, this essentially also applies to the contact pressure element per se. Optionally, the pressure element and / or the rest of the base body may have stiffening elements, which lead to a certain, but not significant deviation from the pure plate shape.

Zum anderen vereinfacht sich die Montage des Aufhängeteils durch die Verschwenkbarkeit des Anpresselements. So kann das Aufhängeteil insbesondere mit zunächst aus der Grundkörper-Hauptebene heraus geschwenktem Anpresselement in die insbesondere als ein C-Profil, vorzugsweise als ein CD-Profil ausgeführte Tragschiene eingesetzt werden. Da in der verschwenkten Montierstellung des Anpresselements vorteilhafterweise keine oder zumindest keine maßgebliche Verspannung mit der Tragschiene gegeben ist, lässt sich das Aufhängeteil im Rahmen eines ersten Montageschritts sehr bequem in die gewünschte Position innerhalb der Tragschiene bringen und danach im Rahmen eines weiteren Montageschritts durch Verschwenken des Anpresselements in dessen Anpressstellung in dieser Position fixieren. Günstig ist es in diesem Zusammenhang auch, dass es sich bei der Montierstellung und insbesondere auch bei der Anpressstellung um vorzugsweise stabile Stellungen handelt, in denen das Anpresselement ohne Krafteinwirkung von außen insbesondere unverändert so stehen bleibt. Während der Montage muss also insbesondere nicht gegen eine (Feder-) Kraftwirkung eines in eine andere Stellung strebenden Elements gearbeitet werden.On the other hand, the assembly of the suspension part is simplified by the pivotability of the contact pressure element. Thus, the suspension part can be used in particular with initially pressed out of the main body main plane out pressing in the particular designed as a C-profile, preferably as a CD profile support rail. Because in the swiveled Mounting position of the contact advantageously advantageously no or at least no significant tension is given to the support rail, the suspension part can be very comfortable in the first position in the desired position within the support rail and then in the context of another assembly step by pivoting the contact pressure in the Anpressstellung in fix this position. It is favorable in this context, too, that the mounting position and in particular also the contact pressure position are preferably stable positions, in which the contact pressure element remains stationary, in particular unchanged, without the action of force from outside. During assembly, therefore, it is not necessary, in particular, to work against a (spring) force effect of an element striving for a different position.

Mittels zweier Biegeabschnitte ergibt sich für das Anpresselement eine besonders gute und stabile Verbindung mit dem übrigen Grundkörper, die insbesondere auch ein mehrfaches Verschwenken oder Hin- und Herbiegen des Anpresselements ermöglicht. Außerdem wird so in der Anpressstellung eine besonders sichere und effiziente Kraftübertragung mittels des Anpresselements und des damit verbundenen übrigen Grundkörpers gewährleistet. Insbesondere bildet die Flucht beider Biegeabschnitte die Schwenkachse.By means of two bending sections results for the contact pressure a particularly good and stable connection with the rest of the base body, which allows in particular a multiple pivoting or bending back and forth of the contact pressure. In addition, a particularly secure and efficient power transmission is ensured by means of the contact pressure element and the associated other base body in the Anpressstellung. In particular, the escape of both bending sections forms the pivot axis.

Es kann insbesondere auch Anwendungsfälle geben, bei denen das Aufhängeteil und die Tragschiene schon ausreichend miteinander verspannt sind, bevor das Anpresselement vollständig in die Grundkörper-Hauptebene eingeschwenkt ist. Auch dann ist das Anpresselement in seiner Anpressstellung verglichen mit der Montierstellung aber insbesondere zumindest in Richtung der Grundkörper-Hauptebene geschwenkt. Gegebenenfalls kann das Anpresselement in dieser Anpressstellung dann noch um einige wenige Winkelgrad, z.B. um bis zu 10°, vorzugsweise nur um bis zu 5°, aus der Grundkörper-Hauptebene heraus geschwenkt sein. Außerdem kann das Anpresselement z.B. Versteifungselemente aufweisen, die selbst bei vollständig in die Grundkörper-Hauptebene eingeschwenkter Stellung des Anpresselements etwas aus der Grundkörper-Hauptebene vorstehen. Diese Konstellationen sind im Rahmen des Erfindungsgegenstandes mit abgedeckt, was durch die Angabe, dass sich das Anpresselement in seiner Anpressstellung "im Wesentlichen" innerhalb der Grundkörper-Hauptebene befindet, zum Ausdruck kommt.In particular, there may also be applications in which the suspension part and the support rail are already sufficiently braced with each other before the contact pressure element is completely pivoted into the main body main plane. Even then, the pressing element is in its contact position compared with the mounting position but in particular pivoted at least in the direction of the main body main plane. If necessary, can the contact pressure in this pressing position then still by a few angular degrees, for example by up to 10 °, preferably only up to 5 °, be pivoted out of the main body main plane out. In addition, the pressing element may, for example, have stiffening elements which protrude somewhat from the main body main plane even when the pressing element is fully pivoted into the main body plane of the main body. These constellations are covered within the scope of the subject invention, which is expressed by the statement that the contact pressure element is in its contact pressure position "substantially" within the main body main plane.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Aufhängeteils ergeben sich aus den Merkmalen der von Anspruch 1 abhängigen Ansprüche. Günstig ist eine Ausgestaltung, bei der das Anpresselement und/oder der mindestens eine Biegeabschnitt dadurch gebildet ist, dass innerhalb des Grundkörpers mindestens eine Materialaussparung vorhanden ist. Bei der Materialaussparung kann es sich z.B. um eine Freistanzung oder Freischneidung handeln. Dies lässt sich sehr einfach und kostengünstig herstellen.Advantageous embodiments of the suspension part according to the invention will become apparent from the features of the dependent claims of claim 1. A configuration is expedient in which the contact pressure element and / or the at least one bending section is formed by the fact that at least one material recess is present within the base body. The material recess may be, for example, a free-punching or free-cutting. This can be very easily and inexpensively.

Gemäß einer weiteren günstigen Ausgestaltung ist das Anpresselement symmetrisch zur Mittenlängsachse ausgebildet oder insbesondere angeordnet. Dies begünstigt eine besonders effiziente Kraftübertragung auf die oder Verspannung mit der Tragschiene.According to a further advantageous embodiment, the pressing element is formed symmetrically to the central longitudinal axis or in particular arranged. This promotes a particularly efficient power transmission to the or clamping with the mounting rail.

Gemäß einer weiteren günstigen Ausgestaltung weist das Anpresselement eine in Richtung der Mittenlängsachse betrachtete obere Hälfte und eine in Richtung der Mittenlängsachse betrachtete untere Hälfte auf, wobei der mindestens eine Biegeabschnitt in der unteren Hälfte des Anpresselements angeordnet ist. Dadurch ergibt sich eine vorteilhafte Hebelwirkung, die das Verschwenken des Anpresselements in die Anpressstellung während der Montage der Deckenunterkonstruktion erleichtert.According to a further favorable embodiment, the contact pressure element has an upper half viewed in the direction of the central longitudinal axis and a lower half viewed in the direction of the central longitudinal axis, wherein the at least one bending section is arranged in the lower half of the contact pressure element. This results in an advantageous leverage, which facilitates the pivoting of the pressing element in the Anpressstellung during assembly of the ceiling substructure.

Gemäß einer weiteren günstigen Ausgestaltung weist das Anpresselement eine mehreckige Form, insbesondere eine im Wesentlichen rechteckige Form oder insbesondere eine im Wesentlichen sechseckige Form, auf. Diese mehreckigen Formen lassen sich einfach herstellen. Außerdem sind insbesondere die sechs- und vorzugsweise die rechteckige Form für die Zwecke des Anpresselements, nämlich insbesondere das Einschwenken in die Anpressstellung und - danach in der Anpressstellung - das Verspannen der beteiligten Komponenten, besonders gut geeignet. Insbesondere drückt die untere Schmalseite eines rechteckigen Anpresselements, dessen Rechteck-Längsrichtung insbesondere parallel zur Mittenlängsachse orientiert ist, im fertig montierten Zustand (also bei in Anpressstellung befindlichem Anpresselement) gegen den Boden der Tragschiene. Insbesondere bildet diese untere Rechteck-Schmalseite somit im Wesentlichen die Anpresskante. Vorzugsweise ist die längere Rechteck-Seitenlänge bei der rechteckigen Ausgestaltung des Anpresselements um den Faktor 2,5 bis 7,5 und insbesondere um den Faktor 3 bis 5 größer als die kürzere Rechteck-Seitenlänge, also die Länge der Rechteck-Schmalseite. Obwohl die eckigen Ausgestaltungen und insbesondere die rechteckige Ausgestaltung des Anpresselements vorteilhaft sind bzw. ist, kann das Anpresselement grundsätzlich auch eine andere Form, beispielsweise eine in etwa runde oder ovale Form, haben.According to a further advantageous embodiment, the contact pressure element has a polygonal shape, in particular a substantially rectangular shape or in particular a substantially hexagonal shape. These polygonal shapes are easy to make. In addition, in particular the hexagonal and preferably the rectangular shape for the purposes of the pressing, namely in particular the swinging into the Anpressstellung and - then in the Anpressstellung - the distortion of the components involved, particularly well suited. In particular, presses the lower narrow side of a rectangular contact pressure element, the longitudinal direction of which is oriented in particular parallel to the central longitudinal axis, in the fully assembled state (that is to say when the contact pressure element is in contact pressure position) against the bottom of the support rail. In particular, this lower rectangular narrow side thus essentially forms the contact edge. Preferably, the longer rectangle side length in the rectangular configuration of the contact pressure element by a factor of 2.5 to 7.5 and in particular by a factor of 3 to 5 is greater than the shorter rectangle side length, ie the length of the rectangular narrow side. Although the angular configurations and in particular the rectangular configuration of the contact pressure element are or is advantageous, the contact pressure element can in principle also have another shape, for example a roughly round or oval shape.

Gemäß einer weiteren günstigen Ausgestaltung steht die untere Anpresskante des Anpresselements in der Anpressstellung des Anpresselements mit einem Überstand über den sonstigen unteren Rand des Grundkörpers vor. Dadurch lässt sich zum einen eine sehr gute Verspannung der beteiligten Komponenten im fertig montierten Zustand erreichen. Zum anderen kann während der Montage gerade das Element, das dem Boden der Tragschiene am nächsten kommt, nämlich das in der Anpressstellung den Überstand aufweisende Anpresselement, in die Montierstellung verschwenkt werden, in der es das Einsetzen des Aufhängeteils in die Tragschiene nicht behindert. Dabei ist der sonstige untere Rand des Grundkörpers, über den das Anpresselement in seiner Anpressstellung mit dem Überstand über-oder vorsteht, als der untere Rand des Grundkörpers ohne Berücksichtigung des Anpresselements zu verstehen. Es handelt sich also insbesondere nur um den ohne das Anpresselement gebildeten Teil des unteren Rand des Grundkörpers.According to a further advantageous embodiment, the lower contact edge of the contact pressure element in the pressing position of the contact pressure element protrudes beyond the other lower edge of the base body. This makes it possible, on the one hand, to achieve a very good clamping of the components involved in the completely assembled state. On the other hand, during assembly, the element which comes closest to the bottom of the mounting rail, namely the contact element having the projection in the contact pressure position, can be pivoted into the mounting position in which it does not obstruct the insertion of the suspension part into the mounting rail. In this case, the other lower edge of the main body over which the pressing element in its Anpressstellung with the supernatant over or protruding to understand as the lower edge of the body without consideration of the pressing. It is thus in particular only the part of the lower edge of the basic body formed without the contact pressure element.

Gemäß einer weiteren günstigen Ausgestaltung weist das Anpresselement eine in Richtung der Mittenlängsachse gemessene Anpresselement-Länge auf, und hat der Überstand des Anpresselements in seiner über den sonstigen unteren Rand des Grundkörpers vorstehenden Anpressstellung eine in Richtung der Mittenlängsachse gemessene Überstandsausdehnung, die höchstens 15 %, insbesondere höchstens 10 % und vorzugsweise höchstens 7,5 %, der Anpresselement-Länge beträgt. Gemäß einer weiteren günstigen Ausgestaltung haben die Ankeransätze jeweils eine zwischen einer oberen Ankerhakenspitze und einem unteren Ankerhakenboden in Richtung der Mittenlängsachse gemessene Ankerhakentiefe, und hat der Überstand des Anpresselements in seiner über den sonstigen unteren Rand des Grundkörpers vorstehenden Anpressstellung eine in Richtung der Mittenlängsachse gemessene Überstandsausdehnung, die im Bereich zwischen dem 0,7-fachen und dem 1,3-fachen, insbesondere zwischen dem 0,8-fachen und dem 1,2-fachen und bevorzugt zwischen dem 0,9-fachen und dem 1,1-fachen der Ankerhakentiefe liegt. Eine Ausdehnung des Überstands gemäß diesen beiden günstigen Ausgestaltungen ist in zweifacher Hinsicht vorteilhaft. Sie ermöglicht zum einen ein sicheres Verspannen des Aufhängeteils mit der C-förmigen Tragschiene. Zum anderen ist der Überstand aber auch noch nicht so groß, dass er die Handhabung beim Einsetzen des Aufhängeteils in die C-förmige Tragschiene beeinträchtigen würde.According to a further advantageous embodiment, the contact pressure element has a contact element length measured in the direction of the central longitudinal axis, and the supernatant of the contact pressure element has a protrusion extent projecting in the direction of the central longitudinal axis in its overpressure position projecting beyond the other lower edge of the main body, which is at most 15%, in particular at most 10% and preferably at most 7.5%, the Anpresselement length is. According to another favorable The armature projections each have an anchor hook depth measured between an upper anchor hook tip and a lower anchor hook bottom in the direction of the central longitudinal axis, and the projection of the contact element has a protrusion extent projecting in the direction of the center longitudinal axis in its area above the other lower edge of the main body 0.7 times and 1.3 times, in particular between 0.8 times and 1.2 times and preferably between 0.9 times and 1.1 times the anchor hook depth. An expansion of the supernatant according to these two favorable embodiments is advantageous in two respects. On the one hand, it enables secure clamping of the suspension part with the C-shaped mounting rail. On the other hand, the supernatant but not so large that it would affect the handling when inserting the suspension part in the C-shaped mounting rail.

Gemäß einer weiteren günstigen Ausgestaltung ist das Anpresselement in seiner Montierstellung um einen Montierstellungswinkel von bis zu 50°, insbesondere von bis 45° und bevorzugt von bis zu 40° aus der Grundkörper-Hauptebene heraus geschwenkt. Insbesondere ist das Anpresselement in seiner Montierstellung nur soweit aus der Grundkörper-Hauptebene heraus geschwenkt, dass es beim Einsetzen des Aufhängeteils in die C-förmige Tragschiene zu keiner Beeinträchtigung kommt. Vorteilhafterweise lässt sich das Aufhängeteil auch bei in Montierstellung befindlichem Anpresselement noch etwas um seine Mittenlängsachse drehen, um das Aufhängeteil zunächst in einer solchermaßen geringfügig verdrehten Stellung in die C-förmige Tragschiene einzusetzen und erst danach in die richtige Position zu drehen, in der dann auch die Ankeransätze unter die abgewinkelten Schenkelenden der Tragschiene greifen (können).According to a further advantageous embodiment, the contact pressure element in its mounting position by a mounting position angle of up to 50 °, in particular of up to 45 ° and preferably of up to 40 ° from the main body main plane panned out. In particular, the contact pressure element in its mounting position is pivoted only far enough out of the main body main plane that it does not interfere with the insertion of the suspension part into the C-shaped mounting rail. Advantageously, the suspension part can still rotate slightly around its central longitudinal axis even when located in the mounting position pressing member to use the suspension part initially in such a slightly twisted position in the C-shaped mounting rail and only then to turn in the correct position, then in the Anchor approaches under the angled leg ends of the support rail grab (can).

Gemäß einer weiteren günstigen Ausgestaltung ist das Anpresselement mit einer mechanischen Anpresselement-Versteifung, insbesondere mit einer Versteifungswölbung, einer Versteifungsprägung oder einer Versteifungssicke, ausgestattet. So resultiert ein mechanisch besonders stabiler Aufbau, bei dem das Anpresselement insbesondere den in der Anpressstellung wirkenden Kräften besonders gut standhält.According to a further advantageous embodiment, the contact pressure element is provided with a mechanical contact pressure element stiffening, in particular with a stiffening curvature, a stiffening embossment or a stiffening bead. This results in a mechanically particularly stable construction, in which the pressure element particularly well withstand the forces acting in the contact pressure forces.

Einander entsprechende Teile sind in den Fig. 1 bis 9 mit denselben Bezugszeichen versehen. Auch Einzelheiten der im Folgenden näher erläuterten Ausführungsbeispiele können für sich genommen eine Erfindung darstellen oder Teil eines Erfindungsgegenstandes sein.Corresponding parts are in the Fig. 1 to 9 provided with the same reference numerals. Also details of the embodiments explained in more detail below can constitute an invention in itself or be part of an inventive subject matter.

In Fig. 1 ist ein Ausführungsbeispiel eines ankerförmigen Aufhängeteils 1 dargestellt, wobei in Fig. 1 lediglich ein aus einem Blech geformter und im Wesentlichen plattenförmiger oder flacher Grundkörper 2 des Aufhängeteils 1 abgebildet ist. Das Aufhängeteil 1 umfasst neben dem Grundkörper 2 auch noch einen in etwa U-förmigen Aufhängebügel 3 (siehe Fig. 4 und 5), der mittels Nieten an dem Grundkörper 2 befestigt ist und dessen oberer U-Schenkel 4 und dessen unterer U-Schenkel 5 miteinander fluchtende Bohrungen 6 und 7 aufweisen, durch die ein Abhängedraht (in Fig. 1 bis 9 nicht mit dargestellt) in an sich bekannter Weiser geführt wird und in veränderbarer Höhenposition fixiert werden kann. Die (nicht mit abgebildeten) Nieten durchsetzen den U-Boden 8 des Aufhängebügels 3 und den Grundkörper 2. Letzterer enthält hierfür entsprechende Durchgangsbohrungen 9.In Fig. 1 an embodiment of an anchor-shaped suspension part 1 is shown, wherein in Fig. 1 only one formed from a sheet metal and substantially plate-shaped or flat body 2 of the suspension part 1 is shown. The suspension part 1 comprises in addition to the main body 2 also has an approximately U-shaped hanger 3 (see 4 and 5 ), which is fastened by rivets to the base body 2 and whose upper U-leg 4 and the lower U-leg 5 have mutually aligned bores 6 and 7 through which a suspension wire (in Fig. 1 to 9 not shown) is guided in a known manner and can be fixed in variable height position. The (not shown) rivets enforce the U-bottom 8 of the hanger 3 and the main body 2. The latter contains corresponding through holes 9th

Der Grundkörper 2 hat eine Mittenlängsachse 10 und erstreckt sich mit seiner Längsausdehnung in Richtung dieser Mittenlängsachse 10. Weiterhin umfasst der Grundkörper 2 bezogen auf die Richtung der Mittenlängsachse 10 zwei seitliche Ränder 11 und 12 sowie einen in Richtung der Mittenlängsachse 10 betrachteten oberen Rand 13 und einen in Richtung der Mittenlängsachse 10 betrachteten unteren Rand 14. Entsprechend der im Wesentlichen flachen Ausgestaltung hat der Grundkörper 2 auch eine Grundkörperhauptebene 15, die der Ebene des plattenförmigen Blech-Ausgangsmaterials entspricht. Die Grundkörper-Hauptebene 15 ist insbesondere aus den Seitenansichten gemäß Fig. 2 und 3 ersichtlich.The main body 2 has a central longitudinal axis 10 and extends with its longitudinal extent in the direction of this central longitudinal axis 10. Furthermore, the base body 2 comprises two lateral edges 11 and 12 relative to the direction of the central longitudinal axis 10 and an upper edge 13 viewed in the direction of the central longitudinal axis 10 and a In the direction of the central longitudinal axis 10 considered lower edge 14. According to the substantially flat configuration of the base body 2 also has a main body main plane 15, which corresponds to the plane of the plate-shaped sheet metal starting material. The main body main plane 15 is in particular from the side views according to FIGS. 2 and 3 seen.

In der unteren Hälfte weist der Grundkörper 2 an seinen beiden seitlichen Rändern 11, 12 jeweils einen Ankeransatz 16 bzw. 17 auf, der jeweils eine obere Ankerhakenspitze 18 sowie einen unteren Ankerhakenboden 19 umfasst. Die Ankerhakenspitze 18 und der Ankerhakenboden 19 sind in Richtung der Mittenlängsachse 10 um eine Ankerhakentiefe T voneinander beabstandet.In the lower half of the base body 2 at its two lateral edges 11, 12 each have an anchor lug 16 and 17, each comprising an upper anchor hook tip 18 and a lower anchor hook bottom 19. The anchor hook tip 18 and the anchor hook bottom 19 are spaced apart in the direction of the central longitudinal axis 10 by an anchor hook depth T from each other.

Geprägte Versteifungsrippen 20 verlaufen ausgehend von dem Bereich der Ankeransätze 16, 17 der Kontur des jeweiligen seitlichen Randes 11 bzw. 12 folgend nach oben. Weiterhin sind geprägte Versteifungsrippen 21 vorhanden, die ausgehend von dem Bereich der Ankeransätze 16, 17 ebenfalls der Kontur des betreffenden seitlichen Randes 11 bzw. 12 folgend in Richtung des unteren Randes 14 verlaufen.Embossed stiffening ribs 20 extend starting from the region of the anchor projections 16, 17 following the contour of the respective lateral edge 11 and 12, respectively. Furthermore, embossed reinforcing ribs 21 are present, which, proceeding from the region of the anchor projections 16, 17, likewise follow the contour of the relevant lateral edge 11 or 12 in the direction of the lower edge 14.

Das Aufhängeteil 1 umfasst außerdem ein Anpresselement 22, das einstückig mittels zweier Biegeabschnitte 23 und 24 mit dem übrigen Grundkörper 2 verbunden ist. Das Anpresselement 22 ist Bestandteil des Grundkörpers 2. Die Biegeabschnitte 23, 24 sind in der unteren Hälfte des im Wesentlichen rechteckigen Anpresselementes 22 an dessen beiden Längsseiten 25, 26 angeformt. Sie liegen auf gleicher Höhe bzw. fluchten miteinander. Sie bilden eine Schwenkachse 27, um die das Anpresselement 22 mittels Hin- und Herbiegens verschwenkbar ist. Das Anpresselement 22 ist insbesondere durch freischneidende Stanzvorgänge aus dem für die Fertigung des Grundkörpers 2 verwendeten Blech-Ausgangsmaterials hergestellt. Aufgrund dieser Stanzvorgänge sind Materialaussparungen 27a innerhalb des Grundkörpers 2 vorhanden, die das Anpresselement 22 abgesehen von den durch die Biegeabschnitte 23, 24 gebildeten Verbindungsstellen zu dem übrigen Grundkörper 2 umgeben. Grundsätzlich kann aber auch eine andere Herstellungsmethode zur Herstellung des einstückig mit dem übrigen Grundkörper 2 verbundenen Anpresselements 22 vorgesehen sein.The suspension part 1 also comprises a pressing element 22, which is integrally connected by means of two bending sections 23 and 24 with the rest of the base body 2. The pressing member 22 is part of the base body 2. The bending portions 23, 24 are integrally formed in the lower half of the substantially rectangular pressing member 22 at its two longitudinal sides 25, 26. They are at the same height or aligned with each other. They form a pivot axis 27 about which the pressing member 22 is pivotable by means of bending back and forth. The pressing element 22 is produced in particular by free-cutting punching processes from the sheet metal starting material used for the production of the main body 2. As a result of these punching operations, material recesses 27a are present within the basic body 2, which surround the pressing element 22 apart from the connecting points formed by the bending sections 23, 24 relative to the remaining basic body 2. Basically, but also a another manufacturing method for producing the integrally connected to the rest of the base body 2 pressing member 22 may be provided.

Eine untere Schmalseite 28 des rechteckigen Anpresselements 22 steht über den ansonsten durch den Grundkörper 2 gebildeten unteren Rand 14 um einen Überstand 29 vor, der eine Überstandsausdehnung D hat, wenn sich das Anpresselement 22 in seiner Anpressstellung befindet. Diese in der Abbildung gemäß Fig. 1 gezeigte Anpressstellung liegt dann vor, wenn sich das Anpresselement 22 im Wesentlichen innerhalb der Grundkörper-Hauptebene 15 befindet. Im Gegensatz dazu ist das Anpresselement 22 bei der in Fig. 2 und 3 abgebildeten Montierstellung aus der Grundkörper-Hauptebene 15 heraus geschwenkt.A lower narrow side 28 of the rectangular contact pressure element 22 projects beyond the lower edge 14, which is otherwise formed by the main body 2, about a projection 29, which has an excess length D when the pressure element 22 is in its press-on position. These in the picture according to Fig. 1 shown pressing position is present when the pressing member 22 is located substantially within the main body main plane 15. In contrast, the pressing member 22 is in the in FIGS. 2 and 3 pictured mounting position pivoted out of the main body main plane 15 out.

Die Überstandsausdehnung D beträgt bei dem gezeigten Ausführungsbeispiel etwa 10 % einer in Richtung der Mittenlängsachse 10 gemessenen Anpresselementlänge L des Anpresselements 22. Bezogen auf die Ankerhakentiefe T liegt die Überstandsausdehnung D bei etwa dem 1,1-fachen dieser Ankerhakentiefe T.The protrusion extent D is in the embodiment shown about 10% of measured in the direction of the center longitudinal axis 10 Anpresselementlänge L of the pressing member 22. Relative to the anchor hook depth T, the supernatant extent D is about 1.1 times this anchor hook depth T.

Das Anpresselement 22 hat eine die mechanische Stabilität erhöhende Versteifungswölbung 29a (siehe insbesondere Fig. 3). Außerdem weist die untere Schmalseite 28 des Anpresselementes 22 Abschrägungen 30 an den Ecken auf, welche das Einschwenken in die in Fig. 1 gezeigte Anpressstellung im endmontierten Zustand (siehe Fig. 5) erleichtern. Der von den Abschrägungen 30 nicht erfasste Teil der unteren Schmalseite 28 bildet eine Anpresskante 28a.The pressing element 22 has a stiffening curvature 29a which increases the mechanical stability (see in particular FIG Fig. 3 ). In addition, the lower narrow side 28 of the pressure element 22 bevels 30 at the corners, which pivoting into the in Fig. 1 shown pressing position in the final assembled state (see Fig. 5 ) facilitate. The part of the lower narrow side 28 not covered by the chamfers 30 forms a contact edge 28a.

Wie bereits erwähnt, ist das Aufhängeteil 1 in den Seitenansichten gemäß Fig. 2 und 3 mit aus der Grundkörper-Hauptebene 15 heraus geschwenktem Anpresselement 22 abgebildet. Das Anpresselement 22 befindet sich in diesem Zustand in seiner Montierstellung, bei der es um einen Montierstellungswinkel α um die Schwenkachse 27 aus der Grundkörper-Hauptebene 15 heraus geschwenkt ist. Der Montierstellungswinkel α liegt bei dem in Fig. 2 und 3 gezeigten Ausführungsbeispiel bei etwa 35°.As already mentioned, the suspension part 1 in the side views according to FIGS. 2 and 3 with pivoted out of the main body main plane 15 out Pressing element 22 shown. The pressing element 22 is in this state in its mounting position, in which it is pivoted about a mounting position angle α about the pivot axis 27 of the main body main plane 15 out. The mounting position angle α is at the in FIGS. 2 and 3 shown embodiment at about 35 °.

Im Folgenden wird die Montage des Aufhängeteils 1 insbesondere auch anhand von Fig. 4 und 5 erläutert.In the following, the assembly of the suspension part 1 in particular also based on 4 and 5 explained.

Das in seiner Montierstellung befindliche Aufhängeteil 1 wird in eine C-förmige Tragschiene 31 einer Deckenunterkonstruktion eingesetzt. Dazu wird das Aufhängeteil 1 zunächst durch eine Drehung um den nicht mit abgebildeten und in etwa parallel zur Mittenlängsachse 10 angeordneten Abhängedraht leicht schräg gestellt. In dieser Schrägstellung wird der untere Abschnitt des Grundkörpers 2 mit den Ankeransätzen 16, 17 in die Öffnung der Tragschiene 31 eingeführt. Danach wird das Aufhängeteil 1 um den Abhängedraht in die korrekte Position zurück gedreht, so dass sich die Ankeransätze 16, 17 unterhalb abgewinkelter Schenkelenden 32 der Tragschiene 31 befinden. Diese Montagesituation ist in Fig. 4 abgebildet. Bei dem gezeigten Ausführungsbeispiel ist die Tragschiene 31 insbesondere als ein CD-Profil ausgeführt.The suspension part 1 located in its mounting position is inserted into a C-shaped mounting rail 31 of a ceiling substructure. For this purpose, the suspension part 1 is initially set slightly inclined by a rotation about the suspension wire not shown and arranged approximately parallel to the central longitudinal axis 10. In this inclined position, the lower portion of the base body 2 with the anchor projections 16, 17 is inserted into the opening of the support rail 31. Thereafter, the suspension part 1 is rotated back around the suspension wire in the correct position, so that the anchor projections 16, 17 are below angled leg ends 32 of the support rail 31. This mounting situation is in Fig. 4 displayed. In the embodiment shown, the support rail 31 is designed in particular as a CD profile.

Daraufhin wird das Anpresselement 22 ausgehend von der Montierstellung um die Schwenkachse 27 in die Anpressstellung geschwenkt. Dadurch kommt die an der unteren Schmalseite 28 des Anpresselements 22 vorgesehene Anpresskante 28a mit einer mittig am Boden der Tragschiene 31 nach oben vorspringenden Erhöhung 33 in Kontakt. Zugleich wird das Aufhängeteil 1 dadurch nach oben gedrückt, wodurch die Ankeransätze 16, 17 unter die Schenkelenden 32 der Tragschiene 31 gedrückt werden. In dieser in Fig. 5 gezeigten fertig montierten Stellung ist ein sicherer und insbesondere verdrehfester Sitz des Aufhängeteils 1 an der Tragschiene 31 gewährleistet. Es liegt eine Dreipunktauflage zwischen der Tragschiene 31 und dem Aufhängeteil 1 vor, deren maßgebliche drei Kontaktstellen zwischen der unteren Schmalseite 28 des Anpresselements 22 und der Erhöhung 33 der Tragschiene 31 sowie zwischen den beiden Ankeransätzen 16, 17 und den abgewinkelten Schenkelenden 32 der Tragschiene 31 gebildet sind. Der feste, insbesondere verdrehfeste Sitz des Aufhängeteils 1 innerhalb der Tragschiene 31 stellt außerdem auch sicher, dass es selbst bei Erschütterungen der Deckenunterkonstruktion zu keinen störenden (Klapper) Geräuschen kommt.Then, the pressing member 22 is pivoted starting from the mounting position about the pivot axis 27 in the Anpressstellung. As a result, the contact edge 28a provided on the lower narrow side 28 of the contact pressure element 22 comes into contact with an elevation 33 projecting upwards in the center at the bottom of the support rail 31. At the same time the suspension part 1 is thereby pressed upwards, whereby the anchor projections 16, 17 are pressed under the leg ends 32 of the support rail 31. In this in Fig. 5 shown fully assembled position is a safe and particularly rotationally secure seat of the suspension part 1 is ensured on the mounting rail 31. There is a three-point support between the support rail 31 and the suspension part 1, the relevant three contact points between the lower narrow side 28 of the pressing member 22 and the increase 33 of the support rail 31 and between the two anchor projections 16, 17 and the angled leg ends 32 of the support rail 31 is formed are. The fixed, in particular rotationally fixed seat of the suspension part 1 within the mounting rail 31 also ensures that there is no disturbing (rattling) noise, even with vibrations of the ceiling substructure.

In Fig. 6 und 7 ist eine nicht erfindungsgemäße Alternative eines Aufhängeteils 34 mit einem ebenfalls ankerförmigen Grundkörper 35 abgebildet. Auch der Grundkörper 35 umfasst ein einstückig angeformtes verschwenkbares Anpresselement 36, das eine untere Anpresskante 37 aufweist, mit der das Anpresselement 36 in seiner in Fig. 6 gezeigten Anpressstellung den sonstigen unteren Rand 14 des Grundkörpers 35 in Richtung der Mittenlängsachse 10 nach unten um den Überstand 29 überragt. Das Anpresselement 36 hat eine im Wesentlichen sechseckige Grundform, wobei die Anpresskante 37 durch eine der sechs Seitenkanten gebildet ist. An der der Anpresskante 37 gegenüberliegenden Seite ist das sechseckige Anpresselement 36 mittels eines Biegeabschnitts 38 mit dem übrigen Grundkörper 35 einstückig verbunden. Der Biegeabschnitt 38 gestattet ein Verschwenken des Anpresselements 36 um eine innerhalb des Biegeabschnitts 38 liegende und im Wesentlichen parallel zur Anpresskante 37 verlaufende Schwenkachse 39. In Fig. 7 ist das Anpresselement 36 in seiner aus der Grundkörper-Hauptebene 15 um den Montierstellungswinkel α heraus geschwenkten Montierstellung gezeigt.In 6 and 7 is a not inventive alternative of a suspension member 34 shown with a likewise anchor-shaped base body 35. Also, the main body 35 includes an integrally formed pivotable pressing member 36 having a lower pressing edge 37, with which the pressing member 36 in his in Fig. 6 shown pressing the other lower edge 14 of the body 35 in the direction of the central longitudinal axis 10 down to the supernatant 29 surmounted. The pressing member 36 has a substantially hexagonal basic shape, wherein the pressing edge 37 is formed by one of the six side edges. On the side opposite the contact edge 37, the hexagonal contact element 36 is integrally connected to the rest of the main body 35 by means of a bending section 38. The bending section 38 permits pivoting of the pressing element 36 about a pivot axis 39 lying within the bending section 38 and extending essentially parallel to the contact edge 37 Fig. 7 the pressing member 36 is shown in its mounted from the main body main plane 15 to the mounting position angle α out tilted mounting position.

Auch das Anpresselement 36 ist mittels Freistanzens hergestellt, so dass zwischen dem Anpresselement 36 und dem übrigen Grundkörper 35 seitliche Freiräume bildende Materialaussparungen 40 vorhanden sind.Also, the pressing member 36 is made by free punching, so that between the pressing member 36 and the rest of the main body 35 lateral clearances forming material recesses 40 are present.

In Fig. 8 und 9 ist eine weitere nicht erfindungsgemäße Alternative eines Aufhängeteils 41 mit einem ankerförmigen Grundkörper 42 abgebildet. Dieser Grundkörper 42 unterteilt sich in einen oberen Abschnitt 43 und einen unteren Abschnitt 44, die mittels eines Biegeabschnitts 45 einstückig miteinander verbunden sind. Der untere Abschnitt 44 des Grundkörpers 42 stellt in seiner Gänze ein um eine innerhalb des Biegeabschnitts 45 verlaufende Schwenkachse 46 verschwenkbares Anpresselement 47 dar. Um die Verschwenkbarkeit des Anpresselements 47 mittels Hin- und Herbiegens zu ermöglichen, sind innerhalb des Biegeabschnitts 45 drei Materialaussparungen 48, 49 vorhanden, wobei die beiden Materialaussparungen 48 gerade im Bereich der oberen Versteifungsrippen 20 angeordnet sind, um deren versteifende Wirkung im Bereich des Biegeabschnitts 45 aufzuheben und somit ein Hin-und Herbiegen bzw. eine Verschwenken des Anpresselements 47 zu erleichtern.In 8 and 9 is another alternative not according to the invention a suspension part 41 with an anchor-shaped base body 42 shown. This main body 42 is divided into an upper portion 43 and a lower portion 44, which are integrally connected to each other by means of a bending portion 45. The lower portion 44 of the base body 42 represents in its entirety a pressing element 47 pivotable about a pivot axis 46 extending inside the bending section 45. In order to enable the pivoting of the pressing element 47 by means of bending back and forth, three material recesses 48, 49 are provided within the bending section 45 present, wherein the two material recesses 48 are arranged just in the region of the upper stiffening ribs 20 in order to cancel their stiffening effect in the region of the bending portion 45 and thus facilitate a back and forth bending or a pivoting of the pressing member 47.

An seinem unteren Rand 14 enthält der Grundkörper 42 einen in Bezug auf die Mittenlängsachse 10 mittig angeordneten Vorsprung 50, an dessen Unterseite eine Anpresskante 51 gebildet ist. Wie gehabt, dient diese Anpresskante 51 zum Verspannen des Aufhängeteils 41 mit der Tragschiene 31, wenn sich das Anpresselement 47 in seiner in Fig. 8 gezeigten Anpressstellung befindet.At its lower edge 14, the base body 42 contains a projection 50 arranged centrally with respect to the central longitudinal axis 10, on the underside of which a contact edge 51 is formed. As usual, this contact edge 51 serves to clamp the suspension part 41 to the support rail 31 when the pressure element 47 is in its in Fig. 8 is shown pressing position.

Der das Anpresselement 47 bildende untere Abschnitt 44 des Grundkörpers 42 lässt sich wiederum durch ein Verbiegen um die Schwenkachse 46 in eine aus der Grundkörper-Hauptebene 15 verschwenkte Montierstellung überführen. Diese Position ist in der in Fig. 9 gezeigten Seitenansicht des Aufhängeteils 41 wiedergegeben.The pressing portion 47 forming lower portion 44 of the body 42 can be in turn by bending about the pivot axis 46 in transfer a tilted from the main body main plane 15 mounting position. This position is in the in Fig. 9 shown side view of the suspension part 41 reproduced.

Der Zusammenbau der Aufhängeteile 34 und 41 mit der Tragschiene 31 erfolgt in ähnlicher Weise wie im Zusammenhang mit dem Aufhängeteil 1 beschrieben. Insbesondere wird zunächst das jeweilige Anpresselement 36 bzw. 47 in die Montierstellung gebracht, um das Einsetzen des betreffenden Grundkörpers 35 bzw. 42 in die Tragschiene 31 zu erleichtern. Danach wird das jeweilige Anpresselement 36 bzw. 47 in seine Anpressstellung zurück gebogen bzw. geschwenkt. Insgesamt bieten also auch die Aufhängeteile 34 und 41 die im Zusammenhang mit dem Aufhängeteil 1 beschriebenen Vorteile.The assembly of the suspension parts 34 and 41 with the support rail 31 is carried out in a similar manner as described in connection with the suspension part 1. In particular, first the respective pressing element 36 or 47 is brought into the mounting position, in order to facilitate the insertion of the relevant base body 35 or 42 into the mounting rail 31. Thereafter, the respective pressing member 36 and 47 is bent back or pivoted in its Anpressstellung. Overall, therefore, the suspension parts 34 and 41 also offer the advantages described in connection with the suspension part 1.

Die Aufhängeteile 1, 34 und 41 eignen sich jeweils sehr gut für eine sichere und effiziente Montage einer Deckenunterkonstruktion. Zugleich lassen sie sich sehr einfach herstellen. Insbesondere ist für die Ausbildung des betreffenden Anpresselements 22, 36 bzw. 47 kein gesondertes Bauteil erforderlich. Vielmehr lässt sich das betreffende Anpresselement 22, 36 bzw. 47 aus demselben Blech-Ausgangsmaterial herstellen wie der übrige Grundkörper 2, 35 bzw. 42 des Aufhängeteils 1, 34 bzw. 41. Dadurch reduzieren sich die Herstellungskosten.The suspension parts 1, 34 and 41 are each very well suited for a safe and efficient installation of a ceiling substructure. At the same time, they are very easy to make. In particular, no separate component is required for the formation of the respective pressing element 22, 36 and 47, respectively. Rather, the respective pressing element 22, 36 or 47 can be made of the same sheet metal starting material as the rest of the base body 2, 35 or 42 of the suspension part 1, 34 and 41. This reduces the manufacturing costs.
