  • the other end of the retaining portion is preferably larger, ie has a larger cross section, than the opening in the reduced diameter portion.

Description

Die vorliegende Erfindung betrifft ein Befestigungssystem zur Befestigung von plattenförmigen Elementen an einem Untergrund sowie ein Verfahren zur Herstellung eines entsprechenden Systems. Bei den Elementen kann es sich unter anderem um Fassadenplatten handeln. Diese Platten sollen in einem einstellbaren Abstand zu dem Untergrund befestigt werden.The present invention relates to a fastening system for fastening panel-shaped elements to a substrate and a method for producing a corresponding system. The elements can be, inter alia, facade panels. These plates should be fixed at an adjustable distance to the subsoil.

Derartige Befestigungssysteme weisen im Allgemeinen ein Befestigungselement zum Befestigen in dem Untergrund und ein tellerförmiges Mittel zum Halten der Platte auf. Im Rahmen der Montage kann es immer wieder mal passieren, dass das Befestigungselement nicht senkrecht in dem Untergrund angeordnet wird. Dies führt dann dazu, dass das Haltemittel nicht parallel zum Untergrund ausgerichtet ist und somit die an dem Haltemittel angeordnete Platte schief ist. Beispielsweise ist die Platte dann nicht parallel zu dem Untergrund angeordnet, sondern ist an einer Stelle näher am Untergrund als an einer anderen Stelle.Such fastening systems generally comprise a fastening element for fastening in the substructure and a plate-shaped means for holding the panel. During assembly, it can happen again and again that the fastening element is not arranged vertically in the subsurface. The result of this is that the holding means is not aligned parallel to the base and the plate arranged on the holding means is therefore crooked. For example, the plate is then not arranged parallel to the ground, but is closer to the ground at one point than at another point.

Grundsätzlich ist es bekannt Gelenkverbindungen zwischen Befestigungselementen und Haltetellern anzuordnen. Ein Befestigungssystem mit Befestigungselement, Halteelement, Halteschaft und Gelenkelement ist aus DE 195 15 904 A1 bekannt. Weitere Gelenkverbindungen sind in DE 43 23 989 A1 oder DE 88 08 787 U1 beschrieben. Die bekannten Gelenkverbindungen haben allerdings den Nachteil, dass sie sehr aufwendig in der Herstellung und bei der Montage sind. Darüber ist bei den bekannten Befestigungssystemen häufig der Abstand zum Untergrund nicht einstellbar oder wenn er einstellbar ist, besteht die Gefahr, dass bei dem Einstellen des Abstands unbemerkt die Wirksamkeit der Verbindung mit dem Untergrund nachlässt.In principle, it is known to arrange articulated connections between fastening elements and holding plates. A fastening system with fastening element, holding element, holding shaft and joint element is made DE 195 15 904 A1 known. More joint connections are in DE 43 23 989 A1 or DE 88 08 787 U1 described. However, the known articulated connections have the disadvantage that they are very complex to manufacture and assemble. In addition, with the known fastening systems, the distance to the substructure is often not adjustable, or if it is adjustable, there is a risk that the effectiveness of the connection to the substructure decreases unnoticed when the distance is adjusted.

Die vorliegende Erfindung stellt sich daher die Aufgabe ein Befestigungssystem bereitzustellen, mit dem eine Platte, insbesondere eine Fassadenplatte in einem einstellbaren Abstand zu einem Untergrund und in einem bestimmten Winkel befestigt werden kann, wobei das Befestigungssystem einfach in der Herstellung und in der Montage sein soll. Darüber hinaus stellt sich die vorliegende Erfindung die Aufgabe entsprechende Verfahren bereitzustellen.The present invention therefore has the task of providing a fastening system with which a panel, in particular a facade panel, can be fastened at an adjustable distance from a substrate and at a certain angle, with the fastening system being easy to manufacture and in the assembly should be. In addition, the object of the present invention is to provide corresponding methods.

Diese Aufgabe wird durch das Befestigungssystem gemäß Anspruch 1 und durch die Verfahren gemäß den Ansprüchen 8 und 9 gelöst. Bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen.This object is solved by the fastening system according to claim 1 and by the methods according to claims 8 and 9. Preferred embodiments emerge from the dependent claims.

Das erfindungsgemäße Befestigungssystem ist ausgestaltet um eine Platte in einem einstellbaren Abstand zu einem Untergrund zu befestigen. Bei der Platte kann es sich insbesondere um eine Fassadenplatte handeln. Das Befestigungssystem weist ein Befestigungselement, ein Halteelement, einen Halteschaft und ein Gelenkelement auf.The fastening system according to the invention is designed to fasten a panel at an adjustable distance from a substrate. The panel can in particular be a facade panel. The fastening system has a fastening element, a holding element, a holding shaft and a joint element.

Das Befestigungselement ist ausgestaltet, um in dem Untergrund befestigt zu werden. Dem Fachmann sind verschiedenste Techniken bekannt, wie eine Befestigungselement in einem Untergrund befestigt werden kann. Das Befestigungselement kann beispielsweise als Nagel oder Schraube ausgestaltet sein, die direkt in dem Untergrund angeordnet werden können. Das Befestigungselement kann aber auch derart ausgestaltet sein, dass es mit einem Hilfsmittel, wie zum Beispiel einem Dübel in dem Untergrund verankert werden kann. Dies sind allerdings nur Beispiele und das Befestigungselement kann auch mit anderen Befestigungstechniken, wie zum Beispiel Kleben oder Verspannen in oder an dem Untergrund befestigt werden.The fastener is designed to be fastened into the ground. A wide variety of techniques are known to those skilled in the art as to how a fastening element can be fastened in a substrate. The fastening element can be designed, for example, as a nail or screw, which can be arranged directly in the ground. However, the fastening element can also be designed in such a way that it can be anchored in the subsurface with a tool, such as a dowel. These are only examples, however, and the fastening element can also be fastened in or on the substrate using other fastening techniques, such as gluing or bracing.

Das erfindungsgemäße Befestigungssystem weist auch ein Halteelement auf. Das Halteelement ist derart ausgestaltet, dass es die zu befestigende Platte halten kann. Hierfür kann das Halteelement Mittel aufweisen, die mit der zu befestigenden Platte verbunden werden können. Um eine bestmögliche Verbindung herstellen zu können, ist das Halteelement häufig tellerförmig ausgestaltet und wird daher auch als Halteteller bezeichnet. Das Halteelement ist aber nicht notwendigerweise auf die Ausgestaltung als Teller oder auf eine andere bestimmte Form beschränkt.The fastening system according to the invention also has a holding element. The holding element is designed in such a way that it can hold the plate to be fastened. For this purpose, the holding element can have means that can be connected to the panel to be fastened. In order to be able to produce the best possible connection, the holding element is often designed in the shape of a plate and is therefore also referred to as a holding plate. However, the holding element is not necessarily limited to the design as a plate or to another specific shape.

Das Befestigungssystem weist außerdem einen Halteschaft auf. Dieser Halteschaft ist an dem Halteelement angeordnet. Erfindungsgemäß weist das Halteelement eine Öffnung auf und an dieser Öffnung befindet sich der Halteschaft. Der Halteschaft weist vorzugsweise einen Bereich auf, in dem das Gelenkelement angeordnet werden kann. Hierbei handelt es sich vorzugsweise um einen Hohlraum, der von wandartigen Bereichen des Halteschafts gebildet wird. Dabei ist der Halteschaft vorzugsweise derart an dem Halteelement angeordnet, dass die Öffnung in dem Halteelement in den Bereich in dem Halteschaft übergeht, in dem das Gelenkelement angeordnet werden soll. Erfindungsgemäß befindet sich in dem Bereich des Halteschafts in dem das Gelenkelement angeordnet werden soll ein Bereich mit einem reduzierten Durchmesser. Dieser Bereich kann sich an einem der Enden des Halteschafts befinden oder irgendwo zwischen den Enden. Ein reduzierter Durchmesser liegt vor, wenn die wandartigen Bereiche des Halteschafts dafür sorgen, dass es in diesem Bereich enger ist als an mindestens einer anderen Stelle in dem Schaft. Der Querschnitt dieses Bereichs mit reduziertem Durchmesser muss nicht notwendigerweise kreisförmig sein, sondern kann auch eckig sein oder eine andere Form aufweisen.The fastening system also has a retaining stem. This holding shaft is arranged on the holding element. According to the invention, the holding element has an opening and the holding shaft is located at this opening. The holding shaft preferably has an area in which the joint element can be arranged. This is preferably a cavity that is formed by wall-like areas of the holding shaft. In this case, the holding shaft is preferably such arranged on the holding element such that the opening in the holding element merges into the area in the holding shaft in which the joint element is to be arranged. According to the invention, an area with a reduced diameter is located in the area of the holding shaft in which the joint element is to be arranged. This area may be at either end of the support shaft or anywhere between the ends. A reduced diameter is when the wall-like portions of the support shaft cause it to be narrower in that area than at least one other location in the shaft. The cross-section of this area with reduced diameter does not necessarily have to be circular, but can also be angular or have another shape.

Darüber hinaus weist das erfindungsgemäße Befestigungssystem ein Gelenkelement auf. Dieses Gelenkelement ist ein wesentliches Element um die gewünschte Winkelverstellbarkeit und die Einstellbarkeit des Abstands zu erzielen. Erfindungsgemäß weist das Gelenkelement eine Durchgangsöffnung auf. Diese Durchgangsöffnung hat an zumindest einer Stelle ein Innengewinde. Dieses Innengewinde ist derart ausgestaltet, dass es mit einem Außengewinde auf dem Befestigungselement verschraubt werden kann. Dabei ist dem Fachmann klar, dass zumindest eines von dem Innengewinde und dem Außengewinde nicht notwendigerweise ein durchgehendes Profil aufweisen muss. Viel mehr können das Innengewinde und das Außengewinde durch alle möglichen Vorsprünge und Ausnehmungen gebildet werden, die eine feste Verbindung zwischen dem Befestigungselement und dem Gelenkelement erzielen und bei denen ein relatives Verdrehen von einem der beiden Elemente gegenüber dem anderen Element dazu führt, dass sich das Gelenkelement relativ zu dem Befestigungselement entlang dem Befestigungselement bewegt. Denn mit Hilfe des Gewindes kann die Position des Gelenkelements auf dem Befestigungselement verändert werden. Durch Drehen des Gelenkelements auf dem Befestigungselement kann das Gelenkelement entweder in Richtung Untergrund oder von dem Untergrund weg bewegt werden.In addition, the fastening system according to the invention has a joint element. This hinge element is an essential element to achieve the desired angular adjustability and distance adjustability. According to the invention, the joint element has a through opening. This through-opening has an internal thread at least at one point. This internal thread is designed in such a way that it can be screwed to an external thread on the fastening element. It is clear to the person skilled in the art that at least one of the internal thread and the external thread does not necessarily have to have a continuous profile. Rather, the internal thread and the external thread can be formed by all sorts of projections and recesses that achieve a firm connection between the fastening element and the joint element and in which a relative twisting of one of the two elements with respect to the other element leads to the joint element moved relative to the fastener along the fastener. Because with the help of the thread, the position of the joint element can be changed on the fastening element. By rotating the joint element on the fastening element, the joint element can be moved either towards the ground or away from the ground.

Das Gelenkelement ist erfindungsgemäß ausgestaltet, um in dem Halteschaft angeordnet zu werden. Dabei kann das Gelenkelement vorzugsweise derart gegenüber dem Halteschaft bewegt werden, dass der Winkel zwischen dem Gelenkelement und dem Halteschaft verändert werden kann. Hierbei kann es sich um eine Winkeländerung in einer Ebene handeln. Gemäß einer bevorzugten Ausführungsform der Erfindung sind der Halteschaft und das Gelenkelement allerdings derart ausgestaltet, dass der Winkel in einem dreidimensionalen Raum geändert werden kann. Wenn das Befestigungssystem beispielsweise an einer im Wesentlichen senkrechten Wand angeordnet ist und sich das Befestigungselement somit im Wesentlich horizontal erstreckt, kann das an dem Halteschaft angeordnete Halteelement beispielsweise in einer Ebene nach oben oder nach unten gekippt werden. Gemäß einer bevorzugten Ausführungsform kann das Haltelement zusätzlich noch nach links oder rechts gekippt werden, d.h. im Raum bewegt werden. Weiter bevorzugt ermöglichen das Gelenkelement und der Halteschaft Kippbewegungen in jede Richtung im Raum. Dies führt dazu, dass die Anordnung des Halteschafts relativ zum Gelenkelement räumlich flexibel ist.According to the invention, the joint element is designed to be arranged in the holding shaft. The joint element can preferably be moved relative to the holding shaft in such a way that the angle between the joint element and the holding shaft can be changed. This can be a change in angle in a plane. However, according to a preferred embodiment of the invention, the support shaft and the articulation element are such designed that the angle can be changed in a three-dimensional space. If the fastening system is arranged, for example, on an essentially vertical wall and the fastening element thus extends essentially horizontally, the holding element arranged on the holding shaft can be tilted upwards or downwards in a plane, for example. According to a preferred embodiment, the holding element can also be tilted to the left or right, ie it can be moved in space. More preferably, the joint element and the holding shaft allow tilting movements in any direction in space. This results in the arrangement of the holding shaft being spatially flexible relative to the joint element.

In einer bevorzugten Ausführungsform bilden eine gedachte Achse durch die Durchgangsöffnung des Gelenkelements und eine rechtwinklig zum Haltelement sich erstreckende gedachte Achse den Winkel. In der vorliegenden Ausführungsform entspricht die gedachte Achse durch die Durchgangsöffnung des Gelenkelements der Längserstreckung des Befestigungselements. Die rechtwinklig zum Haltelement sich erstreckende gedachte Achse geht vorzugsweise durch die Öffnung in dem Haltelement und entspricht vorzugsweise der Längserstreckung des Halteschafts. Wenn die beiden Achsen parallel sind bzw. ineinander übergehen, dann wird in der vorliegenden Erfindung von einem geraden Zustand gesprochen. Wenn die beiden Achsen aber in einem Winkel zueinanderstehen, wird dies als schiefer Zustand bezeichnet.In a preferred embodiment, an imaginary axis through the through opening of the joint element and an imaginary axis extending at right angles to the holding element form the angle. In the present embodiment, the imaginary axis through the through opening of the joint element corresponds to the longitudinal extent of the fastening element. The imaginary axis extending at right angles to the holding element preferably goes through the opening in the holding element and preferably corresponds to the longitudinal extension of the holding shaft. If the two axes are parallel or merge into one another, the present invention speaks of a straight state. However, when the two axes are at an angle to each other, this is referred to as a skewed condition.

Erfindungsgemäß weist das Gelenkelement einen Gelenkbereich und einen Haltebereich auf. Der Gelenkbereich ist vorzugsweise der Bereich des Gelenkelements, der derart in dem Halteschaft bewegt werden kann, dass die Funktion eines Gelenks realisiert werden kann. Mit Hilfe dieses Gelenks wird, wie oben beschrieben, der Winkel zwischen Gelenkelement und Halteschaft verändert. Der Haltebereich des Gelenkelements ist vorzugsweise derart ausgestaltet, dass er das Gelenkelement in dem Halteschaft hält. Das Gelenkelement ist erfindungsgemäß derart ausgestaltet, dass es durch die Öffnung in dem Halteelement in den Halteschaft bewegt werden kann. Der Haltebereich des Gelenkelements ist derart ausgestaltet, dass er durch den Bereich des Halteschafts mit dem reduzierten Durchmesser bewegt werden kann bis sich der Bereich mit dem reduzierten Durchmesser zwischen dem Gelenkbereich und dem Haltebereich des Gelenkelements befindet. In dieser Position wird das Gelenkelement zug- und druckfest in dem Halteschaft gehalten. Eine derartige zug- und druckfeste Halterung ist insbesondere wichtig, wenn mit der zu befestigenden Platte eine hinterlüftete Fassade erstellt wird. In diesem Fall befindet sich an der Innenseite der Platte, also an der Seite der Platte, die in Richtung Untergrund zeigt, kein Element, das ein Bewegen der Platte in Richtung Untergrund verhindern könnte.According to the invention, the joint element has a joint area and a holding area. The joint area is preferably the area of the joint element that can be moved in the holding shaft in such a way that the function of a joint can be implemented. As described above, the angle between the joint element and the holding shaft is changed with the aid of this joint. The holding area of the joint element is preferably designed in such a way that it holds the joint element in the holding shaft. According to the invention, the joint element is designed in such a way that it can be moved into the holding shaft through the opening in the holding element. The holding portion of the hinge member is configured to be moved through the reduced diameter portion of the holding shaft until the reduced diameter portion is between the hinge portion and the holding portion of the hinge member. In this position, the joint element is held in the holding shaft in a manner that is resistant to tension and pressure. Such a tensile and pressure-resistant mount is particularly important when a plate to be fastened ventilated facade is created. In this case, there is no element on the inside of the panel, ie on the side of the panel that points in the direction of the ground, which could prevent the panel from moving in the direction of the ground.

Dadurch, dass das Gelenkelement und der Halteschaft derart ausgestaltet sind, kann das Befestigungssystem einfach hergestellt und montiert werden. Der Halteschaft und das Gelenkelement können separat hergestellt werden und für die Montage wird das Gelenkelement einfach in den Halteschaft geschoben. Durch das Zusammenspiel des Halteschafts und des Gelenkelements entsteht eine zug- und druckfeste Verbindung. Durch das aus Halteschaft und Gelenkelement gebildete Gelenk kann die an dem Halteelement angeordnete Platte gegenüber dem Untergrund ausgerichtet werden. Außerdem kann der Abstand zwischen der Platte und dem Untergrund eingestellt werden, ohne dass die Gefahr besteht, dass unbemerkt die Verbindung des Befestigungssystems geschwächt wird. Denn durch die Öffnung in dem Halteelement kann der Benutzer beispielsweise einfach sehen, ob die Gewindeverbindung zwischen dem Befestigungselement und dem Gelenkelement noch besteht und ob das Gelenkelement von dem Halteschaft gehalten wird.Because the joint element and the holding shaft are designed in this way, the fastening system can be manufactured and installed easily. The holding shaft and the joint element can be manufactured separately and the joint element is simply pushed into the holding shaft for assembly. The interaction of the holding shaft and the joint element creates a connection that is resistant to tension and pressure. The joint formed by the holding shaft and the joint element allows the plate arranged on the holding element to be aligned with respect to the ground. In addition, the distance between the panel and the substructure can be adjusted without the risk of unnoticed weakening of the connection of the fastening system. For example, through the opening in the holding element, the user can easily see whether the threaded connection between the fastening element and the joint element still exists and whether the joint element is held by the holding shaft.

Bei dem erfindungsgemäßen Befestigungssystem ist das Einstellen des Abstands zwischen der zu befestigenden Platte und dem Untergrund auch besonders einfach. Durch ein Drehen des von außen zugänglichen Gelenkelements kann das Gelenkelement auf dem Befestigungselement bewegt werden. Dadurch dass der Benutzer bei dem Einstellen des Abstands den Halteschaft, das Gelenkelement und das Befestigungselement durch die Öffnung in dem Halteelement sehen kann, kann er jede negative Beeinflussung des Befestigungssystems sehen. Beim Drehen des Gelenkelements kann er beispielsweise sehen, ob sich auch das Befestigungselement bewegt und dadurch gegebenenfalls die Verbindung zwischen dem Befestigungselement und dem Untergrund beeinflusst wird.In the case of the fastening system according to the invention, setting the distance between the plate to be fastened and the subsurface is also particularly simple. By turning the joint element accessible from the outside, the joint element can be moved on the fastening element. By allowing the user to see the support shaft, the wrist member and the fastener through the opening in the support member when adjusting the spacing, the user can see any adverse impact on the fastener system. When turning the joint element, he can, for example, see whether the fastening element is also moving and whether the connection between the fastening element and the substructure is influenced as a result.

In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist der Haltebereich des Gelenkelements konusförmig ausgestaltet. Die Verwendung eines konusförmigen Haltebereichs ist eine Möglichkeit, um das Gelenkelement auf einfache Weise in dem Halteschaft anzuordnen, so dass eine zug- und druckfeste Verbindung entsteht. Dabei ist das Ende des konusförmigen Haltebereichs des Gelenkelements mit dem größeren Durchmesser an der dem Gelenkbereich zugewandten Seite angeordnet, während das Ende mit dem geringeren Durchmesser an der anderen Seite des Haltebereichs angeordnet ist. Auch wenn hier von Durchmessern gesprochen wird, soll dies nicht bedeuten, dass der Konus notwendigerweise kreisförmige Querschnitte aufweist. Der Konus kann jede beliebige Form aufweisen. Wenn das Ende, das zuerst durch den Bereich mit reduziertem Durchmesser bewegt wird, kleiner ist, kann es einfacher durch den Bereich mit dem reduzierten Durchmesser bewegt werden. Daher ist das Ende des Haltebereichs, das zuerst durch den Bereich mit reduziertem Durchmesser bewegt wird, vorzugsweise kleiner, d.h. hat einen geringeren Querschnitt, als die Öffnung in dem Bereich mit dem reduzierten Durchmesser. Das andere Ende des Haltebereichs ist vorzugsweise größer, d.h. hat einen größeren Querschnitt, als die Öffnung in dem Bereich mit dem reduzierten Durchmesser. Dadurch wird verhindert, dass sich das Gelenkelement wieder in Richtung Halteelement bewegt. Dabei muss nicht das gesamte Ende größer sein. Es reicht aus, wenn es einen oder mehrere Vorsprünge gibt, die das zug- und druckfeste Halten des Gelenkelements in dem Halteschaft unterstützen.In a preferred embodiment of the present invention, the holding area of the joint element is designed in the shape of a cone. The use of a cone-shaped holding area is one way of arranging the joint element in the holding shaft in a simple manner, so that a connection which is resistant to tension and pressure is produced. The end of the conical holding area of the joint element with the larger diameter is arranged on the side facing the joint area, while the end with the smaller diameter is on the other side of the holding area is arranged. Even if diameters are mentioned here, this does not mean that the cone necessarily has circular cross-sections. The cone can have any shape. If the end that is first moved through the reduced diameter area is smaller, it can be moved through the reduced diameter area more easily. Therefore, the end of the retaining portion that is first moved through the reduced diameter portion is preferably smaller, ie, has a smaller cross section, than the opening in the reduced diameter portion. The other end of the retaining portion is preferably larger, ie has a larger cross section, than the opening in the reduced diameter portion. This prevents the joint element from moving back in the direction of the holding element. The entire end does not have to be larger. It is sufficient if there are one or more projections that support the tensile and pressure-resistant holding of the joint element in the holding shaft.

In einer weiter bevorzugten Ausführungsform sind das Ende des Haltebereichs mit dem größeren Durchmesser und/oder der Bereich mit dem reduzierten Durchmesser des Halteschafts zumindest teilweise flexibel ausgestaltet. Diese Flexibilität ermöglicht, dass der Haltebereich durch den Bereich mit dem reduzierten Durchmesser geschoben werden kann. Aufgrund der Ausgestaltung des Haltebereichs und/oder des Bereichs mit reduziertem Durchmesser wird aber ein zurückschieben des Haltebereichs durch den Bereich mit dem reduzierten Durchmesser erschwert. Durch das Anordnen des Befestigungselements in dem Gelenkelement kann das Zurückschieben noch weiter erschwert werden.In a further preferred embodiment, the end of the holding area with the larger diameter and/or the area with the reduced diameter of the holding shaft are at least partially flexible. This flexibility allows the holding portion to be slid through the reduced diameter portion. However, due to the design of the holding area and/or the area with a reduced diameter, it is made more difficult for the holding area to be pushed back through the area with the reduced diameter. By arranging the fastening element in the joint element, pushing back can be made even more difficult.

In einer bevorzugten Ausführungsform ist das Gelenkelement derart ausgestaltet, dass die zug- und druckfeste Verbindung durch das Einführen des Befestigungselements in das Gelenkelement erreicht wird. Alternativ kann die Zug- und Druckfestigkeit durch das Befestigungselement erhöht werden.In a preferred embodiment, the joint element is designed in such a way that the connection that is resistant to tension and pressure is achieved by inserting the fastening element into the joint element. Alternatively, the tensile and compressive strength can be increased by the fastener.

In einer weiteren bevorzugten Ausführungsform ist das Gelenkelement drehfest in dem Halteschaft angeordnet. Dies führt dazu, dass eine Drehung des Halteschafts auch eine Drehung des Gelenkelements bewirkt. Wenn dann auch noch das Haltelement drehfest mit dem Halteschaft verbunden ist, beispielsweise einstückig, dann kann durch eine Drehung des Halteelements das Gelenkelement gedreht werden und somit der Abstand zwischen der zu befestigenden Platte und dem Untergrund eingestellt werden. Die drehfeste Verbindung wird vorzugsweise durch eine zumindest teilweise formschlüssige aber nicht rotationssymmetrische Ausgestaltung von dem Gelenkelement und dem Halteschaft erzielt.In a further preferred embodiment, the joint element is arranged in the holding shaft in a rotationally fixed manner. As a result, rotation of the support shaft also causes rotation of the joint member. If the holding element is then also non-rotatably connected to the holding shaft, for example in one piece, then the joint element can be rotated by rotating the holding element and thus the distance between the plate to be fastened and the substrate can be adjusted. the a non-rotatable connection is preferably achieved by an at least partially form-fitting but non-rotationally symmetrical design of the joint element and the holding shaft.

In einer weiteren bevorzugten Ausführungsform weist das Halteelement eine Markierung auf, die es dem Benutzer erleichtert festzustellen, ob und wie weit das Halteelement und damit gegebenenfalls auch das Gelenkelement gedreht wurden.In a further preferred embodiment, the holding element has a marking that makes it easier for the user to determine whether and to what extent the holding element and thus possibly also the joint element have been rotated.

Dem Fachmann sind unterschiedliche Mittel bekannt, mit denen eine Platte an dem Halteelement angeordnet werden kann. Vorzugsweise wird mit diesen Mitteln eine kraft-, form- und/oder stoffschlüssigen Verbindung zwischen dem Halteelement und der Platte hergestellt. Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung weist das Haltelement an der dem Untergrund abgewandten Seite stift-, pilzkopf-, haken- und/oder schlingenförmig Mittel auf, um mit der Platte eine Klett-Verbindung herzustellen.Various means are known to those skilled in the art with which a plate can be arranged on the holding element. A non-positive, positive and/or material connection between the holding element and the plate is preferably produced with these means. According to a preferred embodiment of the present invention, the holding element has pin, mushroom head, hook and/or loop-shaped means on the side facing away from the substructure in order to establish a Velcro connection with the plate.

In einer weiteren bevorzugten Ausführungsform weist das Befestigungselement an einem Endbereich eine Werkzeugaufnahme auf. Hierbei handelt es sich vorzugsweise um den Endbereich, der im montierten Zustand von dem Untergrund abgewandt ist. Mit Hilfe der Werkzeugaufnahme kann das Befestigungselement mit einem Werkzeug in dem Untergrund gesetzt werden. Darüber hinaus kann die Werkzeugaufnahme, die beispielsweise durch eine Ausnehmung in der Form eines Sechskants ausgestaltet ist, dem Benutzer helfen zu erkennen, ob sich beim Drehen des Gelenkelements ungewollt das Befestigungselement mitdreht.In a further preferred embodiment, the fastening element has a tool holder in one end area. This is preferably the end area that faces away from the substrate in the assembled state. With the help of the tool holder, the fastening element can be set in the subsurface with a tool. In addition, the tool holder, which is designed, for example, by a recess in the shape of a hexagon, can help the user to recognize whether the fastening element is also turning unintentionally when the joint element is turned.

In einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung weist das Befestigungssystem ein Spannseil auf, das auf der einen Seite, vorzugsweise mit einer Schlaufe oder Öse, an dem Befestigungselement angeordnet ist und an der anderen Seite beispielsweise mit Hilfe eines Befestigungsmittels, beispielsweise einem Dübel, an dem Untergrund befestigt ist. Das Spannseil ist vorzugsweise derart an dem Befestigungselement angeordnet, dass es die Winkelverstellbarkeit und die Einstellbarkeit des Abstands nicht beeinflusst. Der Fachmann weiß, dass statt einem Spannseil auch andere Mittel, wie beispielsweise ein Stab oder eine Stange verwendet werden können.In a further preferred embodiment of the present invention, the fastening system has a tensioning cable which is arranged on one side, preferably with a loop or eyelet, on the fastening element and on the other side, for example with the aid of a fastening means, for example a dowel, on which ground is fixed. The tension cable is preferably arranged on the fastening element in such a way that it does not affect the angular adjustability and the adjustability of the distance. Those skilled in the art know that other means, such as a rod or bar, can be used instead of a tether.

Die Aufgabe wird auch durch ein Verfahren zur Herstellung eines Befestigungssystems zum Befestigen einer Platte, insbesondere einer Fassadenplatte in einem einstellbaren Abstand zu einem Untergrund gelöst. Im Rahmen des Verfahrens wird ein Gelenkelement in einen Halteschaft eingeführt, bis sich ein Haltebereich des Gelenkelements hinter einem Bereich des Halteschafts mit reduziertem Durchmesser befindet. Anschließend wird das Gelenkelement mit einem Befestigungselement zur Befestigung an einem Untergrund verschraubt.The object is also achieved by a method for producing a fastening system for fastening a panel, in particular a facade panel, at an adjustable distance from a substrate. The method involves inserting an articulation member into a support shaft until a support portion of the articulation member is rearward of a reduced diameter portion of the support shaft. The joint element is then screwed to a fastening element for fastening to a substrate.

Erfindungsgemäß wird die Aufgabe auch durch ein Verfahren zum Befestigen einer Platte, insbesondere einer Fassadenplatte in einem einstellbaren Abstand zu einem Untergrund mit Hilfe eines Befestigungssystems gelöst. Im Rahmen des Verfahrens wird ein Befestigungselement des Befestigungssystems in oder an dem Untergrund befestigt. Außerdem wird ein Gelenkelement mit einem Halteschaft und einem Halteelement des Befestigungssystems an dem Befestigungselement angeordnet, wobei dies vor oder nach dem Befestigen an dem Untergrund stattfinden kann. Erfindungsgemäß wird der Abstand des Halteelements von dem Untergrund durch Drehen des Gelenkelements gegenüber dem Befestigungselement eingestellt und das Halteelement durch Verkippen des Halteschafts relativ zu dem Gelenkelement ausgerichtet.According to the invention, the object is also achieved by a method for fastening a panel, in particular a facade panel, at an adjustable distance from a substrate using a fastening system. As part of the method, a fastening element of the fastening system is fastened in or on the substrate. In addition, a joint element with a retaining shaft and a retaining element of the fastening system is arranged on the fastening element, which can take place before or after fastening to the substructure. According to the invention, the distance between the holding element and the ground is adjusted by rotating the joint element relative to the fastening element, and the holding element is aligned by tilting the holding shaft relative to the joint element.

Figur 1 zeigt eine Außenansicht einer Ausführungsform eines Befestigungssystems 1 gemäß der vorliegenden Erfindung im schiefen Zustand. Figur 2 zeigt eine Schnittansicht der Ausführungsform des Befestigungssystems 1 im geraden Zustand. figure 1 shows an external view of an embodiment of a fastening system 1 according to the present invention in the crooked state. figure 2 shows a sectional view of the embodiment of the fastening system 1 in the straight state.

Das Befestigungssystem 1 ist bestimmt, um eine Platte 2 an einem Untergrund 3 zu befestigen. Das Befestigungssystem weist ein Befestigungselement 4, ein Halteelement 5, einen Halteschaft 6 und ein Gelenkelement 8 auf. Das Befestigungselement 4 ist ein Element mit dem das Befestigungssystem 1 an dem Untergrund 3 befestigt wird. Hierbei kann es sich beispielsweise um einen Metallstab handeln. In der in den Figuren 1 und 2 veranschaulichten Ausführungsform wird das Befestigungselement 4 aus mehreren Teilen gebildet. Es besteht aus einer Schraube 4a und einer Gewindestande 4b, die mit einer Hülse 4c miteinander verbunden sind. Dies ist aber nur ein Beispiel. Wie oben erläutert, kennt der Fachmann eine Vielzahl von Möglichkeiten, wie das Befestigungselement 4 ausgestaltet sein kann und wie es an dem Untergrund 3 befestigt werden kann.The fastening system 1 is designed to fasten a panel 2 to a substrate 3 . The fastening system has a fastening element 4 , a holding element 5 , a holding shaft 6 and a joint element 8 . The fastening element 4 is an element with which the fastening system 1 is fastened to the substrate 3 . This can be a metal rod, for example. In the in the Figures 1 and 2 illustrated embodiment, the fastener 4 is formed of multiple parts. It consists of a screw 4a and a thread 4b, which are connected to each other with a sleeve 4c. But this is just an example. As explained above, the person skilled in the art knows a large number of possibilities for how the fastening element 4 can be designed and how it can be fastened to the substrate 3 .

Das Befestigungselement 4 ist mit dem Gelenkelement 8 verbunden. Hierfür weist das Befestigungselement 4 ein Außengewinde auf, das mit einem Innengewinde in einer Durchgangsöffnung 9 (siehe Figur 3) des Gelenkelements 8 verschraubt werden kann. An der Außenseite des Gelenkelements 8 ist ein Halteschaft 6 angeordnet, der wiederum mit einem Halteelement 5 verbunden ist. Das Halteelement 5 weist Mittel auf, die ein Halten beziehungsweise ein Befestigen der Platte 2 ermöglichen. In der in den Figuren gezeigten Ausführungsform sind der Haltschaft 6 und das Halteelement 5 einstückig realisiert. Dies muss aber nicht notwendigerweise der Fall sein. Der Halteschaft 6 und das Halteelement 5 können auch aus separaten Teilen gebildet werden, wobei der Halteschaft 6 und das Halteelement 5, wie auch die anderen hier beschriebenen Elemente beziehungsweise Bauteile jeweils auch aus mehreren Teilen bestehen können, so wie dies oben im Zusammenhang mit dem Befestigungselement 4 erläutert und veranschaulicht ist.The fastening element 4 is connected to the joint element 8 . For this purpose, the fastening element 4 has an external thread which is connected to an internal thread in a through-opening 9 (see figure 3 ) of the joint element 8 can be screwed. A holding shaft 6 is arranged on the outside of the joint element 8 and is in turn connected to a holding element 5 . The holding element 5 has means which enable the plate 2 to be held or fastened. In the embodiment shown in the figures, the holding shaft 6 and the holding element 5 are realized in one piece. However, this does not necessarily have to be the case. The holding shaft 6 and the holding element 5 can also be formed from separate parts, whereby the holding shaft 6 and the holding element 5, as well as the other elements or components described here, can also consist of several parts, as is the case above in connection with the fastening element 4 is explained and illustrated.

Das Gelenkelement 8 ist derart in dem Halteschaft 6 angeordnet, dass der Winkel zwischen dem Gelenkelement 8 beziehungsweise dem mit dem Gelenkelement 8 verschraubten Befestigungselement 4 und dem Halteschaft 6 beziehungsweise dem daran angeordneten Halteelement verändert werden kann. Wie beispielsweise in Figur 2 veranschaulicht, ist eine gedachte Achse durch die Durchgangsöffnung des Gelenkelements parallel zu einer gedachten Achse, die sich rechtwinklig zum Haltelement durch die Öffnung in dem Halteelement erstreckt. Deshalb wird die Anordnung als gerader Zustand bezeichnet. In Figur 1 stehen die beiden gedachten Achsen in einem Winkel zueinander. Diese Anordnung wird deshalb auch als schiefer Zustand bezeichnet. Durch diese Verstellbarkeit des Winkels wirken sich schief in dem Untergrund angeordnete Befestigungselement nicht auf die Ausrichtung der zu befestigenden Platten aus.The joint element 8 is arranged in the holding shaft 6 in such a way that the angle between the joint element 8 or the fastening element 4 screwed to the joint element 8 and the holding shaft 6 or the holding element arranged thereon can be changed. As for example in figure 2 As illustrated, an imaginary axis through the through opening of the hinge member is parallel to an imaginary axis extending perpendicularly to the support member through the opening in the support member. Therefore, the arrangement is referred to as an even state. In figure 1 the two imaginary axes are at an angle to each other. This arrangement is therefore also referred to as a skewed state. As a result of this adjustability of the angle, fastening elements arranged askew in the substrate do not affect the alignment of the panels to be fastened.

In Figur 3 wird die Anordnung des Gelenkelements 8 in dem Halteschaft 6 detaillierter dargestellt. Der Halteschaft 6 weist einen Bereich 7 mit einem reduzierten Durchmesser auf. In der hier gezeigten Ausführungsform bewirkt das Zusammenspiel zwischen diesem Bereich 7 mit reduziertem Durchmesser und dem Gelenkelement 8, dass das Gelenkelement 8 zug- und druckfest in dem Halteschaft 6 gehalten wird. Wenn auf das Halteelement 5 ein Druck in Richtung Untergrund 3 ausgeübt wird, kommt es aufgrund der Ausgestaltung des Gelenkelements 8 und des Halteschafts 6 nicht zu einer Relativbewegung zwischen dem Gelenkelement 8 und dem Halteschaft 6. Genauso wird die Verbindung zwischen dem Gelenkelement 8 und dem Halteschaft 6 nicht durch ein Ziehen an dem Halteelement 5 von dem Untergrund 3 weg beeinflusst.In figure 3 the arrangement of the joint element 8 in the holding shaft 6 is shown in more detail. The holding shaft 6 has a region 7 with a reduced diameter. In the embodiment shown here, the interaction between this area 7 with a reduced diameter and the joint element 8 causes the joint element 8 to be held in the holding shaft 6 in a manner that is resistant to tension and pressure. If pressure is exerted on the holding element 5 in the direction of the substrate 3, there is no relative movement between the joint element 8 and the holding shaft 6 due to the design of the joint element 8 and the holding shaft 6. The connection between the joint element 8 and the holding shaft is the same 6 is not influenced away from the substrate 3 by pulling on the holding element 5 .

In der hier gezeigten Ausführungsform weist das Gelenkelement 8 einen Gelenkbereich 8a und einen Haltebereich 8b auf. Die hauptsächliche Funktion des Gelenkbereichs 8a ist es zusammen mit dem Halteschaft 6 ein Gelenk zu bilden. Mit diesem Gelenk kann der Halteschaft 6 in einem Winkel zu dem Gelenkelement 8 angeordnet werden. Figur 4 zeigt wie sich der Halteschaft 6 relativ zu dem Gelenkelement 8 bewegt, damit die beiden in einem Winkel zueinanderstehen, d.h. schief sind.In the embodiment shown here, the joint element 8 has a joint area 8a and a holding area 8b. The main function of the hinge portion 8a is to form a hinge together with the support shaft 6. With this joint, the holding shaft 6 can be arranged at an angle to the joint element 8 . figure 4 Figure 12 shows how the support shaft 6 moves relative to the joint element 8 so that the two are at an angle to one another, ie are skewed.

Bei der in den Figuren gezeigten Ausführungsform sind das Gelenkelement 8 und der Halteschaft 6 derart ausgestaltet, dass der Winkel von beiden zueinander im Raum geändert werden kann. Der Winkel kann also nicht nur in zwei Richtungen verändert werden, wie dies bei einer Winkeländerung in einer Ebene der Fall wäre, sondern in mehr als zwei Richtungen, vorzugsweise in alle Richtungen. In der in den Figuren gezeigten Ausführungsform wird die Veränderbarkeit in mehr als zwei Richtungen dadurch erzielt, dass der Gelenkbereich 8a des Gelenkelements 8 und der Halteschaft 6 jeweils zumindest teilweise die Form eines Kugelsegments, das auch als Kugelkalotte bezeichnet wird, ausgestaltet sind. Bei einer derartigen Ausgestaltung kann die Winkelveränderung zwischen Gelenkelement 8 und Halteschaft 6 räumlich frei erfolgen.In the embodiment shown in the figures, the joint element 8 and the holding shaft 6 are designed in such a way that the angle of both to each other can be changed in space. The angle can therefore not only be changed in two directions, as would be the case with an angle change in one plane, but in more than two directions, preferably in all directions. In the embodiment shown in the figures, the changeability in more than two directions is achieved in that the joint area 8a of the joint element 8 and the holding shaft 6 are each at least partially designed in the shape of a spherical segment, which is also referred to as a spherical cap. With such a configuration, the change in angle between the joint element 8 and the holding shaft 6 can take place in a spatially free manner.

In der in den Figuren gezeigten Ausführungsform weist das Gelenkelement 8 auch noch eine Werkzeugaufnahme 10 auf. Mit Hilfe dieser Werkzeugaufnahme 10 kann das Gelenkelement 8 schnell mit einem Werkzeug, wie beispielsweise einem Akkuschrauber, auf das Befestigungselement 4 geschraubt werden, beispielsweise bis zu einer Ausgangsposition. In dieser Ausführungsform hat die Werkzeugaufnahme 10 die Form eines Sechskants.In the embodiment shown in the figures, the joint element 8 also has a tool holder 10 . With the help of this tool holder 10, the joint element 8 can be quickly screwed onto the fastening element 4 with a tool, such as a cordless screwdriver, for example up to a starting position. In this embodiment, the tool holder 10 has the shape of a hexagon.

Damit das Befestigungssystem 1 einfach und kostengünstig hergestellt werden kann, sind das Gelenkelement 8 und der Halteschaft 6 derart ausgestaltet. dass das Gelenkelement 8 durch eine Öffnung 5a in dem Halteelement 5 in die Position bewegt werden kann, in der der Bereich 7 mit dem reduzierten Durchmesser des Halteschafts 6 zwischen dem Gelenkbereich 8a und dem Haltebereich 8b angeordnet ist.So that the fastening system 1 can be manufactured simply and inexpensively, the joint element 8 and the holding shaft 6 are designed in this way. that the hinge member 8 can be moved through an opening 5a in the holding member 5 to the position where the reduced diameter portion 7 of the holding shaft 6 is located between the hinge portion 8a and the holding portion 8b.

Figur 5 zeigt eine Draufsicht auf das Halteelement 5. Durch die Öffnung 5a in dem Halteelement 5 sieht man den Halteschaft 6, das Gelenkelement 8 mit der Werkzeugaufnahme 10 und das Befestigungselement 4, so dass man bei der Montage des Befestigungssystems sehen kann, ob die Gewindeverbindung zwischen dem Befestigungselement 4 und dem Gelenkelement 8 noch besteht und ob das Gelenkelement 8 von dem Halteschaft 6 gehalten wird. Darüber hinaus weist das Halteelement 5 eine Markierung 11 auf mit deren Hilfe ein Benutzer feststellen kann, ob und wie weit das Halteelement 5 und gegebenenfalls auch das Gelenkelement 8 gedreht wurden. figure 5 shows a top view of the holding element 5. Through the opening 5a in the holding element 5 you can see the holding shaft 6, the joint element 8 with the tool holder 10 and the fastening element 4, so that you can see when assembling the fastening system whether the threaded connection between the Fastening element 4 and the joint element 8 still exists and whether the joint element 8 is held by the holding shaft 6. In addition, the holding element 5 has a marking 11 with the aid of which a user can determine whether and to what extent the holding element 5 and possibly also the joint element 8 have been rotated.
