  • the central region of the connecting means makes positive contact with the base element.
  • At least the lower section of the central region is designed such that, after rotation by the defined angle, it projects beyond the recess of the base element and thereby makes positive contact with the base element from above.

  • the connecting means is supported in its horizontal position by the central region lying on both sides.
  • the entire section of the middle region (also referred to as the transverse side) projecting beyond the recess is flush with the sides of the upper region. This results in a less complex connecting means, which through the enlarged side surface represents a better entrainment profile.

  • the length of the central region is configured such that it holds the first element at a defined distance from the base element during the rotational connection.

  • the central region has a circular cross section. Insofar as it is in contact with the first element with this central region, it does not displace these elements when the connecting means rotates. As a result, a first element can be removed or exchanged without the adjacent elements having to be moved. For example, in the case of a surface laid out with the first elements, a centrally located first element can be exchanged without problems. Especially with larger areas, such as terraces or roofs, this means a considerable time advantage.

  • the width of the upper region is equal to or smaller than the circular cross section of the central region. This means that its width does not exceed the middle area (see here Figure 5 , Representation top right).
  • This has the advantage that when the connecting means is aligned, in which it does not engage with the projecting connecting parts in the first element, it lies flush with the adjacent first elements and these elements can simply be pulled out upwards.
  • the lower region of the connecting means with the projecting connecting parts is designed as a trapezoidal prism with a rectangular base.
  • the trapezoidal prism is preferably oriented such that the base is wider and the prism tapers upwards.
  • the form-fitting engagement of a trapezoid prism designed in this way in a correspondingly complementarily shaped support profile ensures particularly secure fastening, since the connecting means forms a kind of spigot in the profile and prevents it from slipping out upwards.
  • two opposite edges are rounded or beveled in the trapezoidal prism, so that the corresponding upward-pointing edges are preferably rounded or beveled in the same way. This facilitates rotation of the connecting means in the complementarily shaped recesses in the carrier profile. In a special embodiment, all four edges are rounded or beveled.

  • both the top surface and the bottom surface can be beveled, so that the projecting connecting part forms a V-profile in the case of two bevelled surfaces.
  • This surface which is bevelled upwards, proves to be particularly advantageous in the closure according to the invention by rotation, since it can intervene without problems in the case of a first element which has a complementarily configured recess and can press this first element onto the carrier profile in the course of the rotation.
  • This embodiment is therefore contrary to that in FIG WO 2011/149371 Disclosed lanyard, in which the downwardly tapered recesses just prevent screwing into the support profile.
  • the clamping effect which is caused by the combination of the downward force, must be exerted by considerable force beveled area is achieved with the box-shaped recess of the plank to be overcome.
  • the surface which is bevelled upwards is particularly advantageous in the case of first elements which are not exactly shaped.
  • the bevelled surface allows an intervention in the corresponding recess in the plank even in the event of poor contact with the support profile, and the entire upper connecting part is then in only by the rotation the corresponding recess in the screed is screwed in and the screed is pressed against the support profile by the positive contact.

Description

Die vorliegende Erfindung betrifft ein arretierbares Verbindungsmittel zur Verbindung von mindestens einem ersten Element mit einem Basiselement unter Drehung um einen definierten Winkel. Die Erfindung betrifft weiterhin ein Verfahren zur Verbindung von Planken oder Brettern zu einem Trägerprofil unter Verwendung des erfindungsgemäßen Verbindungsmittels.The present invention relates to a lockable connecting means for connecting at least one first element to a base element while rotating through a defined angle. The invention further relates to a method for connecting planks or boards to a support profile using the connecting means according to the invention.

Verbindungsmittel zur Verbindung von zwei Elementen sind zahlreich aus dem Stand der Technik bekannt. Dies trifft auch für Verbindungsmittel zu, die zur Verbindung von Brettern oder Planken zu einem Profilträger verwendet werden.Connection means for connecting two elements are numerous known from the prior art. This also applies to connecting means that are used to connect boards or planks to a profile beam.

So offenbart die Patentanmeldung EP 2 096 232 A1 ein Verbindungsmittel, das einen Halteteil, einen Abstandsteil und einen hohlen Schaft aufweist. Zur Befestigung der Planke oder Bohle auf einem Profilträger wird allerdings ein zusätzliches Befestigungselement wie eine Schraube benötigt. Zudem ist die Befestigung bei unter Spannung stehenden Elementen umständlich und fehleranfällig, da nicht nur das Verbindungsmittel sondern auch die Planke oder Bohle in der gewünschten Position festgehalten werden muss, solange bis die Schraube die Verbindung hergestellt hat. Zum Lösen der Verbindung muss hier erst wieder die Schraube entfernt werden.So the patent application discloses EP 2 096 232 A1 a connecting means having a holding part, a spacing part and a hollow shaft. However, an additional fastening element such as a screw is required to fasten the plank or screed to a profile beam. In addition, the attachment of live elements is cumbersome and prone to errors, since not only the connecting means but also the plank or screed must be held in the desired position until the screw has made the connection. To loosen the connection, the screw must first be removed again.

Die WO 2011/149371 betrifft ein Verbindungsmittel zur Befestigung von Profilen, bei der das Verbindungsmittel zunächst eine drehschlüssige Verbindung mit einem Trägerprofil eingeht und dann in einem zweiten Schritt mit einem aufgelegten Profil verbunden wird. Nachteilig ist hier, dass somit zur Befestigung zwei Arbeitsschritte benötigt werden, und dass die Befestigung im zweiten Schritt nur unter erheblichem Kraftaufwand (Hämmern, siehe Figur 4) zu bewerkstelligen ist.The WO 2011/149371 relates to a connecting means for fastening profiles, in which the connecting means first enters into a rotational connection with a carrier profile and is then connected in a second step to an applied profile. The disadvantage here is that two work steps are required for fastening, and that the fastening in the second step requires considerable effort (hammering, see Figure 4 ) is to be accomplished.

Die EP 2 664 731 A1 betrifft ein Verbindungsmittel zur Befestigung von Planken auf ein Trägerprofil. Das Verbindungsmittel weist einen zylinderförmigen Kopf auf, wobei dieser den kreisrunden Querschnitt des mittleren Bereichs allseitig überragt. Dadurch muss das Verbindungmittel zunächst in das Trägerprofil eingeführt werden und unter Kraftaufwand an die Planke herangeführt werden, was eine aufwändigere Montage bedeutet. Zudem können nach der Montage einzelne, mittelständige Planken nicht einfach entfernt oder ausgetauscht werden.The EP 2 664 731 A1 relates to a connecting means for fastening planks to a support profile. The connecting means has a cylindrical head, which projects beyond the circular cross section of the central region on all sides. As a result, the connecting means must first be inserted into the support profile and brought up to the plank with the application of force, which means a more complex assembly. moreover single, medium-sized planks cannot be easily removed or replaced after assembly.

Die US 2014/096469 A1 betrifft ein Verbindungsmittel mit zwei vorstehenden Verbindungsteilen (s. Figuren 2 und 3) von komplexer plattenförmiger Struktur, die den mittleren Bereich überragen und durch ihre rechteckige Ausgestaltung nach einer Montage zwischen zwei Planken nicht wieder durch Drehung gelöst werden können.The US 2014/096469 A1 relates to a connecting means with two projecting connecting parts (s. Figures 2 and 3 ) of complex plate-shaped structure, which protrude above the central area and, due to their rectangular configuration, cannot be loosened again by rotation after installation between two planks.

Die WO 2011/149371 A1 betrifft ein Verbindungsmittel mit vorstehenden Verbindungsteilen im oberen und unteren Bereich, die durch einen mittleren Schaft voneinander getrennt sind (s. Fig. 9). Auch hier kann durch die rechteckige Ausgestaltung der Verbindungsteile das Verbindungelement nach einer Montage zwischen zwei Planken nicht wieder durch Drehung gelöst werden.The WO 2011/149371 A1 relates to a connecting means with projecting connecting parts in the upper and lower region, which are separated from one another by a central shaft (see FIG. 9). Here, too, the rectangular design of the connecting parts means that the connecting element cannot be loosened again by rotation after installation between two planks.

Die US 2004/101673 A1 betrifft ein Verbindungselement zur Befestigung von Planken auf einer Unterlage. Das Verbindungselement benötigt zur Befestigung ein zusätzliches Befestigungsmittel wie einen Nagel oder eine Schraube, was eine aufwändigere Montage bedeutet.The US 2004/101673 A1 relates to a connecting element for fastening planks to a base. The connecting element requires an additional fastener such as a nail or a screw for fastening, which means a more complex assembly.

Aufgabe der Erfindung ist es daher ein gattungsgemäßes Verbindungsmittel dahingehend zu verbessern, dass eine einfache Demontage von bereits befestigen Elementen erlaubt, indem diese Elemente nach Entriegelung der Verbindungselemente einfach nach oben herausgezogen werden können.The object of the invention is therefore to improve a generic connecting means in such a way that simple dismantling of already fastened elements is possible by simply pulling these elements upwards after unlocking the connecting elements.

Zusammenfassung der ErfindungSummary of the invention

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass ein Verbindungsmittel zur Verbindung von mindestens einem ersten Element zu einem Basiselement bereitgestellt wird, das die Merkmale des Anspruchs 1 aufweist. Bevorzugte Ausführungsformen sind in den Unteransprüchen definiert.This object is achieved according to the invention in that a connecting means for connecting at least one first element to a base element is provided, which has the features of claim 1. Preferred embodiments are defined in the subclaims.

Das erfindungsgemäße Verbindungsmittel vereinigt mehrere entscheidende Vorteile gegenüber den aus dem Stand der Technik bekannten Befestigungsvorrichtungen.The connecting means according to the invention combines several decisive advantages over the fastening devices known from the prior art.

Die Befestigung wird durch einen einfachen Drehvorgang erreicht, der ohne zusätzliche Elemente mit einfachen Hilfsmitteln (und in einer Ausführung sogar mit der Hand) durchführbar ist.The attachment is achieved by a simple turning process, which can be carried out without additional elements using simple tools (and in one version even by hand).

Das anspruchsgemäße Arretierungsmittel sorgt hier dafür, dass keine fehlerhafte oder unzureichende Befestigung resultiert, da sie ein Überdrehen des Verbindungsmittels erschwert oder sogar verhindert. Sie bietet dem Anwender ein deutliches Zeichen, dass er eine optimale Befestigung erzeugt hat und ist daher als ein nicht zu unterschätzendes Sicherheitsmerkmal anzusehen.The sophisticated locking means ensures that no incorrect or inadequate fastening results, since it makes it difficult or even impossible to overtighten the connecting means. It offers the user a clear sign that he has created an optimal fastening and is therefore to be regarded as a safety feature that should not be underestimated.

Die beiden zu verbindenden Elemente werden während des Drehvorgangs miteinander verbunden. Bei entsprechender Ausgestaltung des mindestens einen ersten Elements und des Basiselements werden diese erst während des Drehvorgangs zueinander bewegt, bis sie in bevorzugter Weise in einem festen Kontakt stehen. Dadurch können auch in der Form abweichende, bzw. verformte Elemente drehschlüssig miteinander verbunden werden.The two elements to be connected are connected to each other during the turning process. With a corresponding design of the at least one first element and the base element, they are only moved towards one another during the turning process until they are in firm contact in a preferred manner. As a result, elements that are different or deformed can also be connected to one another in a rotationally locking manner.

Bei dem erfindungsgemäßen Verbindungsmittel kann auch eine Person alleine, bzw. ohne weitere Hilfsmittel wie eine Schraubzwinge die Befestigung durchführen, da mit einer Hand die beiden Elemente zueinander positioniert werden können und mit der zweiten Hand (oder einem damit gehaltenen Drehwerkzeug) das Verbindungsmittel gedreht wird.In the case of the connecting means according to the invention, a person can also carry out the attachment alone, or without further aids such as a screw clamp, since the two elements can be positioned relative to one another with one hand and the connecting means is rotated with the second hand (or a turning tool held thereby).

Es hat sich gezeigt, dass bei dem erfindungsgemäßen Verbindungsmittel die drehschlüssige Arretierung zu einer festen und dauerhaften Befestigung führt. Zusätzliche Befestigungsmittel wie Schrauben oder Nägel sind in der Regel nicht erforderlich.It has been shown that in the connecting means according to the invention the rotational locking leads to a firm and permanent attachment. Additional fasteners such as screws or nails are generally not required.

Da die Befestigung lediglich durch eine Drehung des Verbindungsmittels erfolgt, handelt es sich um eine reversible Befestigung, die schnell und unkompliziert auch wieder aufgehoben werden kann.Since the attachment is done only by rotating the connecting means, it is a reversible attachment that can be quickly and easily removed again.

Damit eignet sich das erfindungsgemäße Verbindungsmittel insbesondere für Systeme, die mit einem häufigen Umbau einhergehen, so z.B. für den Messebau oder für Ordnungssysteme.The connecting means according to the invention is therefore particularly suitable for systems which are associated with frequent conversions, e.g. for stand construction or for organization systems.

Das Verbindungsmittel kann durch seine konkrete Gestaltung gezielt an die Befestigungserfordernisse angepasst werden. So können mehr als zwei Elemente miteinander verbunden werden oder die Stärke der Befestigung kann variiert werden.The connection means can be specifically adapted to the fastening requirements due to its concrete design. In this way, more than two elements can be connected or the strength of the fastening can be varied.

Das Verbindungsmittel ist kompatibel mit herkömmlichen Trägerprofilen oder zu befestigenden Elementen, so dass diese weiterverwendet werden können.The connecting means is compatible with conventional carrier profiles or elements to be fastened so that they can be used again.

Das Verbindungsmittel kann aus einer Vielzahl von Materialien hergestellt werden, um so den unterschiedlichen Anforderungen gerecht zu werden.The lanyard can be made from a variety of materials to meet different needs.

Ausführliche Beschreibung der ErfindungDetailed description of the invention

In einer bevorzugten Ausführungsform ist die erfindungsgemäße Verbindung eine reversible Verbindung, insofern sie eine drehschlüssige Arretierung ohne zusätzliche Befestigungsmittel darstellt.In a preferred embodiment, the connection according to the invention is a reversible connection, insofar as it represents a rotational locking without additional fastening means.

In Ausführungsform der Erfindung ist das Verbindungsmittel mit einem solchen Arretierungsmittel versehen. In einer alternativen Ausführungsform weist das Basiselement ein solches Arretierungsmittel auf. In einer dritten Ausführungsform besitzen sowohl das Verbindungsmittel als auch das Basiselement ein Arretierungsmittel.In an embodiment of the invention, the connecting means is provided with such a locking means. In an alternative embodiment, the base element has such a locking means. In a third embodiment, both the connecting means and the base element have a locking means.

In einer bevorzugten Ausführungsform der Erfindung geht das Arretierungsmittel bei Drehung des Verbindungsmittels um den definierten Winkel mit einem Einrasten des Verbindungsmittels im Basiselement einher. Dies wird dadurch gewährleistet, dass nur bei Erreichen des definierten Winkels das Verbindungsmittel eine formschlüssige Verbindung mit dem Basiselement eingeht.In a preferred embodiment of the invention, when the connecting means rotates through the defined angle, the locking means is associated with the connecting means snapping into the base element. This is ensured by the fact that only at When the defined angle is reached, the connecting means enters into a positive connection with the base element.

Durch das Einrasten wird gewährleistet, dass das Verbindungsmittel nicht nur eine Drehung über den definierten Winkel hinaus erschwert oder verhindert, sondern auch ein Zurückdrehen erschwert oder verhindert. Das Einrasten gibt dem Anwender ein klares Signal, das der optimale Drehungswinkel und damit die optimale Befestigung erhalten worden ist.The engagement ensures that the connecting means not only complicates or prevents rotation beyond the defined angle, but also hinders or prevents it from turning back. The snap-in gives the user a clear signal that the optimal angle of rotation and thus the optimal fastening has been obtained.

Erfindungsgemäß kann das Basiselement mit einem Arretierungsmittel ausgestaltet sein. Dies kann eine, beispielsweise als Haken ausgestaltete, Sperre sein, die in ein entsprechendes Gegenstück im Verbindungsmittel eingreift und ein Weiterdrehen über den definierten Winkel hinaus verhindert.According to the invention, the base element can be designed with a locking means. This can be a lock, designed for example as a hook, which engages in a corresponding counterpart in the connecting means and prevents further rotation beyond the defined angle.

Erfindungsgemäß werden bei dem Verbindungsmittel der untere und der obere Bereich durch einen mittleren Bereich getrennt, der bevorzugt in die Vertiefung des Basiselements einfügbar ist, und der in seinem unteren Abschnitt bevorzugt in Kontakt mit den Seitenwänden der Vertiefung steht. Durch einen solcherart ausgestalteten mittleren Bereich kann eine stabilere Befestigung erhalten werden, da das Verbindungsmittel durch den Kontakt mit den Seiten der Vertiefung auch schon ohne Drehschluss eine stabile Lage in dem Basiselement aufweist.According to the invention, the lower and the upper region are separated in the connecting means by a central region which can preferably be inserted into the depression of the base element and which is preferably in contact with the side walls of the depression in its lower section. A more stable attachment can be obtained by means of a central region designed in this way, since the connecting means has a stable position in the base element even without a rotational connection due to the contact with the sides of the depression.

In einer bevorzugten Form kann auch der mittlere Bereich ein Arretierungsmittel aufweisen und so zur sicheren Befestigung an dem Basiselement beitragen. Bei dieser Variante ist es bevorzugt, dass der mittlere Bereich des Verbindungsmittels einen formschlüssigen Kontakt mit dem Basiselement eingeht.In a preferred form, the central area can also have a locking means and thus contribute to secure attachment to the base element. In this variant, it is preferred that the central region of the connecting means makes positive contact with the base element.

In einer bevorzugten Ausführungsform ist zumindest der untere Abschnitt des mittleren Bereichs so ausgestaltet, dass er nach Drehung um den definierten Winkel die Aussparung des Basiselementes überragt und dabei von oben einen formschlüssigen Kontakt mit dem Basiselement eingeht. Dadurch entsteht eine Klemmwirkung, die das Verbindungselement an das Basiselement presst. Gleichzeitig wird das Verbindungsmittel durch den beidseitig aufliegenden mittleren Bereich in seiner horizontalen Position gestützt.In a preferred embodiment, at least the lower section of the central region is designed such that, after rotation by the defined angle, it projects beyond the recess of the base element and thereby makes positive contact with the base element from above. This creates a clamping effect that presses the connecting element against the base element. At the same time, the connecting means is supported in its horizontal position by the central region lying on both sides.

In einer weiterhin bevorzugten Position ist der gesamte, die Aussparung überragende Abschnitt des mittleren Bereichs (im Folgenden auch als Querseite bezeichnet) flächenbündig mit den Seiten des oberen Bereichs. Dadurch wird ein weniger komplexes Verbindungsmittel erhalten, dass durch die vergrößerte Seitenfläche einen besseres Mitnahmeprofil darstellt.In a further preferred position, the entire section of the middle region (also referred to as the transverse side) projecting beyond the recess is flush with the sides of the upper region. This results in a less complex connecting means, which through the enlarged side surface represents a better entrainment profile.

Zweckmäßigerweise kann auch die Längsseite (d.h. die quer zur Aussparung stehenden Seite) des mittleren Bereichs in ihrer Länge beliebig variiert werden, wobei dadurch der Abstand der ersten Elemente definiert wird.The length of the long side (i.e. the side transverse to the recess) of the central region can also be expediently varied in length, thereby defining the distance between the first elements.

In einer Ausführungsform ist der mittlere Bereich von seiner Länge so ausgestaltet, dass er das erste Element bei der drehschlüssigen Verbindung in einem definierten Abstand zu dem Basiselement hält. Dies wird durch die separaten festen Verbindungen von Verbindungsmittel zu Basiselement einerseits und von Verbindungsmittel zu erstem Element andererseits ermöglicht.In one embodiment, the length of the central region is configured such that it holds the first element at a defined distance from the base element during the rotational connection. This is made possible by the separate fixed connections from the connecting means to the base element on the one hand and from the connecting means to the first element on the other.

Dadurch ist eine Rahmenbauweise möglich, bei dem Basiselement als Grundlage, mindestens zwei Verbindungselemente als Stützen und das mindestens eine erste Element als Dachelement den Rahmen bilden können.This enables a frame construction in which the base element as the basis, at least two connecting elements as supports and the at least one first element as the roof element can form the frame.

In einer bevorzugten Ausführungsform ist der mittlere Bereich von seiner Länge so ausgestaltet, dass das mindestens eine erste Element nach drehschlüssiger Verbindung in Kontakt mit dem Basiselement steht und in bevorzugter Weise an das Basiselement gepresst wird. Dadurch wird ein fester Verbund dieser drei Elemente erreicht.In a preferred embodiment, the length of the central region is configured such that the at least one first element is in contact with the base element after a rotational connection and is preferably pressed against the base element. This creates a firm bond between these three elements.

Erfindungsgemäß weist der mittlere Bereich einen kreisrunden Querschnitt auf. Insofern er mit diesem mittleren Bereich in Kontakt mit dem ersten Elementen steht, verdrängt er somit nicht diese Elemente bei einer Drehung des Verbindungsmittels. Dadurch kann ein erstes Element entfernt oder ausgetauscht werden, ohne dass die benachbarten Elemente verschoben werden müssen. So kann beispielweise bei einer mit den ersten Elementen ausgelegten Fläche ein mittig gelegenes erstes Element ohne Probleme ausgetauscht werden. Gerade bei größeren Flächen, wie bei Terrassen oder Dächern bedeutet dies einen erheblichen Zeitvorteil.According to the invention, the central region has a circular cross section. Insofar as it is in contact with the first element with this central region, it does not displace these elements when the connecting means rotates. As a result, a first element can be removed or exchanged without the adjacent elements having to be moved. For example, in the case of a surface laid out with the first elements, a centrally located first element can be exchanged without problems. Especially with larger areas, such as terraces or roofs, this means a considerable time advantage.

In zweckmäßiger Weise ist der mittlere Bereich hierbei als gerader Kreiszylinder ausgeformt. In dieser leicht herstellbaren Form weist das Verbindungsmittel in diesem Bereich eine maximale Stabilität auf.The middle region is expediently shaped as a straight circular cylinder. In this easily manufactured form, the connecting means has maximum stability in this area.

In einer bevorzugten Ausführungsform ist der mittlere Bereich in seinem oberen Anteil von kreisrundem Querschnitt und in seinem unteren Anteil von rechteckigem Querschnitt. Dieser untere Anteil ist bevorzugt an zwei gegenüberliegenden Kanten abgeschrägt. Hierbei greift der untere Anteil des mittleren Bereichs bevorzugt in das Basiselement ein und trägt zusammen mit den vorspringenden Verbindungsteilen des unteren Bereichs zur Verankerung des Verbindungsmittels in dem Basiselement bei. Bei dieser Ausführungsform weist das Basiselement eine entsprechend zweiteilige Vertiefung auf, die in einem oberen Bereich vertikale Seitenwände aufweist (diese stehen mit dem unteren Anteil des mittleren Bereiches in Kontakt) und in ihrem unteren Bereich seitliche Aussparungen aufweist (diese stehen mit den vorspringenden Verbindungsteilen des unteren Bereichs in Kontakt).In a preferred embodiment, the central region is of circular cross section in its upper portion and of rectangular cross section in its lower portion. This lower portion is preferably bevelled on two opposite edges. Here, the lower portion of the central area preferably engages in the base element and, together with the projecting connecting parts of the lower area, contributes to anchoring the connecting means in the base element. In this embodiment, the base element has a corresponding two-part depression, which has vertical side walls in an upper region (these are in contact with the lower portion of the central region) and has lateral recesses in its lower region (these are in contact with the projecting connecting parts of the lower region) Area in contact).

Erfindungsgemäß ist der obere Bereich in seiner Breite gleichgroß oder kleiner als der kreisrunde Querschnitt des mittleren Bereichs. Dadurch überragt er in seiner Breite nicht den mittleren Bereich (siehe hierzu Figur 5, Darstellung oben rechts). Dies hat den Vorteil, dass bei einer Ausrichtung des Verbindungsmittels, bei der es mit seinen vorspringenden Verbindungsteilen nicht in das erste Element eingreift, damit seitenbündig an den benachbarten ersten Elementen anliegt und diese Elemente einfach nach oben herausgezogen werden können.According to the invention, the width of the upper region is equal to or smaller than the circular cross section of the central region. This means that its width does not exceed the middle area (see here Figure 5 , Representation top right). This has the advantage that when the connecting means is aligned, in which it does not engage with the projecting connecting parts in the first element, it lies flush with the adjacent first elements and these elements can simply be pulled out upwards.

In einer bevorzugten Ausführungsform der Erfindung ist bei dem Verbindungsmittel der untere Bereich mit dem vorspringenden Verbindungsteilen als Trapezprisma mit rechteckiger Basis ausgestaltet ist. In bevorzugter Weise ist das Trapezprisma so ausgerichtet, dass die Basis breiter ist und sich das Prisma nach oben verjüngt. Durch das formschlüssige Eingreifen eines so gestalteten Trapezprismas in ein entsprechend komplementär ausgeformtes Trägerprofil wird ein besonders sichere Befestigung gewährleistet, da das Verbindungsmittel gewissermaßen eine Verzapfung in dem Profil bildet und dadurch ein Herausrutschen nach oben verhindert wird.In a preferred embodiment of the invention, the lower region of the connecting means with the projecting connecting parts is designed as a trapezoidal prism with a rectangular base. The trapezoidal prism is preferably oriented such that the base is wider and the prism tapers upwards. The form-fitting engagement of a trapezoid prism designed in this way in a correspondingly complementarily shaped support profile ensures particularly secure fastening, since the connecting means forms a kind of spigot in the profile and prevents it from slipping out upwards.

Besonders bevorzugt ist hierbei, dass bei dem Trapezprisma zwei gegenüberliegenden Kanten abgerundet oder abgeschrägt ist, so dass auch die entsprechenden nach oben weisenden Kanten bevorzugt in gleicher Weise abgerundet oder abgeschrägt sind. Hierdurch wird eine Drehung des Verbindungsmittels in der komplementär ausgeformten Aussparungen des Trägerprofils erleichtert. In einer besonderen Ausführungsform sind alle vier Kanten abgerundet bzw. abgeschrägt.It is particularly preferred here that two opposite edges are rounded or beveled in the trapezoidal prism, so that the corresponding upward-pointing edges are preferably rounded or beveled in the same way. This facilitates rotation of the connecting means in the complementarily shaped recesses in the carrier profile. In a special embodiment, all four edges are rounded or beveled.

In einer Ausführungsform der Erfindung weist bei dem Verbindungsmittel das mindestens eine vorspringende Verbindungsteil des oberen Bereiches eine abgeschrägte Fläche auf, d.h. eine Flächen, die nach oben oder nach unten abgeschrägt ist. In bevorzugter Weise ist diese Fläche hierbei nach oben abgeschrägt. Die abgeschrägte Fläche ist hierbei als die unterseitige, d.h. Richtung Basiselement ausgerichtete Fläche aufzufassen. Das vorspringende Verbindungsteil kann nur eine abgeschrägte Fläche aufweisen, so dass beispielsweise in Verbindung mit einer oberseitigen geraden Fläche insgesamt eine Trapezform resultiert (s. Figur 1). Alternativ können sowohl die oberseitig als auch die unterseitige Fläche abgeschrägt sein, so dass das vorspringende Verbindungsteil im Fall von zwei nach oben abgeschrägten Flächen ein V-Profil ausbildet.In one embodiment of the invention, in the connecting means, the at least one projecting connecting part of the upper region has a chamfered surface, ie a surface that is chamfered upwards or downwards. This surface is preferably beveled upwards. The beveled surface is to be understood as the surface on the underside, ie oriented towards the base element. The projecting connecting part can have only one beveled surface, so that, for example, in connection with a straight surface on the top side, a trapezoidal shape results overall (see FIG. Figure 1 ). Alternatively, both the top surface and the bottom surface can be beveled, so that the projecting connecting part forms a V-profile in the case of two bevelled surfaces.

Diese nach oben abgeschrägte Fläche erweist sich bei dem erfindungsgemäßen Verschluss durch Drehung als besonders vorteilhaft, da sie bei einem ersten Element dass eine komplementär ausgestaltete Aussparung aufweist, ohne Probleme eingreifen kann und im Verlauf der Drehung dieses erste Element auf das Trägerprofil herunterdrücken kann. Diese Ausführungsform ist somit konträr zu dem in der WO 2011/149371 offenbarten Verbindungsmittel, bei der die nach unten abgeschrägten Aussparungen ein Hineindrehen in das Trägerprofil gerade verhindern. Hier muss durch erheblichen Kraftaufwand die Klemmwirkung, die durch die Kombination der nach unten abgeschrägten Fläche mit der kastenförmigen Aussparung der Planke erzielt wird, überwunden werden.This surface, which is bevelled upwards, proves to be particularly advantageous in the closure according to the invention by rotation, since it can intervene without problems in the case of a first element which has a complementarily configured recess and can press this first element onto the carrier profile in the course of the rotation. This embodiment is therefore contrary to that in FIG WO 2011/149371 Disclosed lanyard, in which the downwardly tapered recesses just prevent screwing into the support profile. Here, the clamping effect, which is caused by the combination of the downward force, must be exerted by considerable force beveled area is achieved with the box-shaped recess of the plank to be overcome.

Die nach oben abgeschrägte Fläche ist besonders bei ersten Elementen vorteilhaft, die nicht exakt ausgeformt sind. So kann beispielsweise bei langen Bohlen, die sich gerade bei dem Material Holz verwinden können, durch die nach abgeschrägte Fläche ein Eingriff in die entsprechende Aussparung der Bohle auch bei mangelndem Kontakt mit dem Trägerprofil erfolgen und erst durch die Drehung wird dann das gesamte obere Verbindungsteil in die entsprechende Aussparung der Bohle eingedreht und durch den formschlüssigen Kontakt die Bohle an das Trägerprofil gepresst.The surface which is bevelled upwards is particularly advantageous in the case of first elements which are not exactly shaped. For example, in the case of long planks, which can twist in the material of wood, the bevelled surface allows an intervention in the corresponding recess in the plank even in the event of poor contact with the support profile, and the entire upper connecting part is then in only by the rotation the corresponding recess in the screed is screwed in and the screed is pressed against the support profile by the positive contact.

In einer Ausführungsform der Erfindung sind bei dem Verbindungsmittel im oberen Bereich genau N vorspringenden Verbindungsteile ausgebildet, wobei N gleich 1, 2, 3, 4, 5, 6, 7, 8, 9 oder 10 sein kann. Bevorzugt ist N hier 1, 2, 3, oder 4, besonders bevorzugt ist N gleich 1, 2, oder 3 und insbesondere bevorzugt ist N gleich 2.In one embodiment of the invention, exactly N projecting connecting parts are formed in the upper region of the connecting means, where N can be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10. N is preferably 1, 2, 3 or 4, particularly preferably N is 1, 2 or 3 and particularly preferably N is 2.

In einer bevorzugten Ausführungsform sind die N vorspringenden Verbindungsteile des oberen Bereichs in einem Winkel von 360/N Grad zueinander positioniert.In a preferred embodiment, the N projecting connecting parts of the upper region are positioned at an angle of 360 / N degrees to one another.

Diese bevorzugte Positionierung für die N vorspringenden Verbindungsteile ist in der folgenden Tabelle 1 dargestellt. Des Weiteren sind in der Tabelle 1 der daraus resultierende Winkelbereich für den definierten Winkel bei dem der Verschluss erfolgen kann und auch der optimale Drehschlusswinkel angegeben. Tabelle 1: Positions- und Drehwinkel für die N vorspringenden Verbindungsteile N Positionswinkel Bereich f. definierten Winkel der Drehung Optimaler Winkel der Drehung 1 - 1° - 359° 90° 2 180° 1° - 179° 90° 3 120° 1° - 119° 60° 4 90° 1° - 89° 45° 5 72° 1° - 71° 36° 6 60° 1° - 59° 30° 7 51,4° 1° - 50° 25,7° 8 45° 1° - 44° 22,5° 9 40° 1°- 39° 22° 10 36° 1° - 35° 18° This preferred positioning for the N projecting connectors is shown in Table 1 below. Furthermore, the resulting angular range for the defined angle at which the closure can take place and also the optimal angle of rotation are given in Table 1. Table 1: Position and rotation angle for the N projecting connecting parts N position angle Area f. defined angle of rotation Optimal angle of rotation 1 - 1 ° - 359 ° 90 ° 2 180 ° 1 ° - 179 ° 90 ° 3 120 ° 1 ° - 119 ° 60 ° 4 90 ° 1 ° - 89 ° 45 ° 5 72 ° 1 ° - 71 ° 36 ° 6 60 ° 1 ° - 59 ° 30 ° 7 51.4 ° 1 ° - 50 ° 25.7 ° 8th 45 ° 1 ° - 44 ° 22.5 ° 9 40 ° 1 ° - 39 ° 22 ° 10 36 ° 1 ° - 35 ° 18 °

So sind beispielsweise bei einem Verbindungselement mit zwei vorspringenden Verbindungsteilen (N=2) diese Verbindungsteile gegenüberliegend angeordnet (Positionswinkel = 180°) und stellen bei einer Drehung des Verbindungselements um den definierten Winkel von 90° die Verbindung des mindestens einen ersten Elements mit dem Basiselement her.For example, in the case of a connecting element with two projecting connecting parts (N = 2), these connecting parts are arranged opposite one another (position angle = 180 °) and, when the connecting element rotates through the defined angle of 90 °, connects the at least one first element to the base element ,

In einer Ausführungsform der Erfindung stellt das Verbindungselement die Verbindung von genau einem ersten Element zu dem Basiselement dar, bevorzugt ist allerdings die Verbindung von 2 oder mehr Elementen, wobei es sich bei diesen bevorzugt um 2, 3, 4, 5,6 7, 8, 9, oder 10 erste Elemente handeln kann.In one embodiment of the invention, the connecting element represents the connection of exactly one first element to the base element, however, the connection of 2 or more elements is preferred, these being preferably 2, 3, 4, 5, 6, 7, 8 , 9, or 10 first elements can act.

Zweckmäßigerweise entspricht die Anzahl der vorspringenden Verbindungsteile (in der vorangehenden Beschreibung mit N bezeichnet) der Anzahl der ersten Elemente die hier zur Verbindung kommen. Sollen also zwei erste Elemente mit dem Basiselement verbunden werden, so weist das Verbindungsmittel zweckmäßigerweise zwei vorspringende Verbindungsteile im oberen Bereich auf. Entsprechend sind es dann bei drei ersten Elementen drei vorspringende Verbindungsteile.The number of projecting connecting parts (designated N in the preceding description) expediently corresponds to the number of first elements which are connected here. If two first elements are to be connected to the base element, the connecting means expediently has two projecting connecting parts in the upper region. Accordingly, there are three projecting connecting parts in the case of three first elements.

In einer Ausführungsform der Erfindung greifen die Verbindungsteile des oberen Bereiches in eine Aussparung des ersten Elementes ein, wobei sich diese Aussparung innerhalb der Seitenfläche des ersten Elementes befindet. Dies kann beispielsweise durch eine innerhalb der Seitenfläche ausgestaltete Nut erreicht werden. In einer alternativen Ausführungsform kann sich diese Aussparung auch auf der Oberseite des Elementes befinden, so dass es sich hier beispielsweise um eine Einkerbung oder zurückgesetzte Kante handelt. In einer weiteren Ausführungsform ist die Oberkante des ersten Elementes selber als Aussparung anzusehen. Hierbei drückt das Verbindungsmittel von oben auf das erste Element und stellt somit auch ohne seitenflächige etablierte Aussparung eine Verbindung zu dem Basiselement her.In one embodiment of the invention, the connecting parts of the upper region engage in a recess in the first element, this recess being located within the side surface of the first element. This can be achieved, for example, by means of a groove designed within the side surface. In an alternative embodiment, this cutout can also be located on the top of the element, so that this is, for example, a notch or a recessed edge. In a further embodiment, the upper edge of the first element itself can be regarded as a recess. Here, the connecting means presses on the first element from above and thus establishes a connection to the base element even without an established recess on the side.

Erfindungsgemäß ist unter einer Aussparung des mindestens einen ersten Elements nicht nur eine Aussparung innerhalb dieses Elementes zu verstehen, sondern auch eine Aussparung auf der Oberseite des ersten Elementes oder die Oberkante selber sind als Aussparungen im Sinne der Erfindung anzusehen.According to the invention, a recess of the at least one first element is not only to be understood as a recess within this element, but also a recess on the upper side of the first element or the upper edge itself are to be regarded as recesses in the sense of the invention.

Die Größe des Verbindungsmittels kann gemäß der zu verbindenden ersten Elemente und Basiselemente variieren. Das Verbindungsmittel weist bevorzugt eine Höhe von 10 bis 50 mm, besonders bevorzugt von 15 bis 30 mm und insbesondere von 20 bis 25 mm auf. Die Breite des Verbindungsmittels, gegeben durch die Außenmaße der vorspringenden Verbindungsteile im oberen Bereich, liegt in einer Ausführungsform zwischen 10 und 50 mm, bevorzugt zwischen 20 und 40 mm und besonders bevorzugt bei ca. 30 mm. Die Schmalseite des unteren Bereichs, die zweckmäßigerweise der Breite der Vertiefung des Basiselements entspricht liegt bevorzugt zwischen 7.5 und 30 mm, besonders bevorzugt zwischen 10 und 20 mm und insbesondere bei ca. 15 mm.The size of the connecting means can vary according to the first elements and basic elements to be connected. The connecting means preferably has a height of 10 to 50 mm, particularly preferably 15 to 30 mm and in particular 20 to 25 mm. In one embodiment, the width of the connecting means, given by the outer dimensions of the projecting connecting parts in the upper region, is between 10 and 50 mm, preferably between 20 and 40 mm and particularly preferably about 30 mm. The narrow side of the lower region, which suitably corresponds to the width of the depression of the base element, is preferably between 7.5 and 30 mm, particularly preferably between 10 and 20 mm and in particular approximately 15 mm.

Bei einer Ausgestaltung des unteren Bereichs als Trapezprisma sind die unteren Innenwinkel der schrägen Trapezflächen zwischen 100 und 140°, bevorzugt zwischen 110 und 130° und besonders bevorzugt zwischen 115 und 125°.In a configuration of the lower area as a trapezoidal prism, the lower inner angles of the oblique trapezoidal surfaces are between 100 and 140 °, preferably between 110 and 130 ° and particularly preferably between 115 and 125 °.

In einer Ausführungsform der Erfindung ist das mindestens eine erste Element ausgewählt aus der Gruppe enthaltend Behälter, Platte, Leiste, Brett, Planke oder Diele.In one embodiment of the invention, the at least one first element is selected from the group comprising a container, plate, bar, board, plank or board.

In bevorzugter Weise ist das mindestens eine Element ein Brett oder eine Planke.The at least one element is preferably a board or a plank.

Bei mehr als einem ersten Element sind diese in einer Ausführungsform identisch, so dass beispielsweise zwei Dielen, zwei Behälter, zwei Leisten oder zwei Bretter mit einem Basiselement verbunden werden können.In the case of more than one first element, these are identical in one embodiment, so that, for example, two planks, two containers, two strips or two boards can be connected to a base element.

In einer alternativen Ausführungsform können diese ersten Elemente auch unterschiedlich sein, wobei hier jede Kombination der vorgenannten (und weiterer) ersten Elemente möglich ist. So können ein Behälter und eine Leiste zusammen durch das Verbindungselement mit dem Basiselement verbunden werden.In an alternative embodiment, these first elements can also be different, any combination of the aforementioned (and further) first elements being possible here. A container and a bar can thus be connected to the base element by the connecting element.

Das mindestens eine erste Element weist eine Aussparung auf, in die die Verbindungsteile des oberen Bereichs des Verbindungsmittels eingreifen.The at least one first element has a recess into which the connecting parts of the upper region of the connecting means engage.

Diese Aussparung ist bevorzugt komplementär ausgeformt, so dass das vorspringende Verbindungsteil im verbundenen Zustand formschlüssig hierzu ist.This recess is preferably of a complementary shape, so that the projecting connecting part in the connected state is form-fitting to this.

In einer bevorzugten Ausführungsform ist die Aussparung breiter als es für das Verbindungselement notwendig ist. Hierbei kann sie sich über einen breiten Bereich des ersten Elementes erstrecken, der mindestens 10%, bevorzugt mindestens 25% und besonders bevorzugt mindestens 50% der entsprechenden Seite des ersten Elements umfasst.In a preferred embodiment, the recess is wider than is necessary for the connecting element. It can extend over a wide range of the first element, which is at least 10%, preferably at least 25% and particularly preferably comprises at least 50% of the corresponding side of the first element.

In einer speziellen Ausführungsform der Erfindung erstreckt sich die Aussparung über die gesamte Länge der entsprechenden Seite des ersten Elementes, sie kann in diese Ausgestaltung auch als Nut bezeichnet werden.In a special embodiment of the invention, the recess extends over the entire length of the corresponding side of the first element; in this embodiment, it can also be referred to as a groove.

So kann beispielweise eine Diele, Bohle, Planke oder Leiste als Deckelemente an mindestens einer, bevorzugt aber an beiden Seitenflächen eine Aussparung aufweisen, die sich über die gesamte Länge der Diele, Bohle, Planke oder Leiste zieht. Somit kann dieses Element flexibel an dem Basiselement (bevorzugt ein Profilträger) positioniert werden, da die gesamte Länge für die Verbindung mit dem erfindungsgemäßen Verbindungsmittel zur Verfügung steht. Zweckmäßigerweise sind beide Seitenflächen mit Aussparungen versehen. So kann mit den Dielen, Bohlen, Planken oder Leisten unter Verwendung des Verbindungsmittels eine ganze Fläche ausgelegt werden, wobei jeweils zwei Deckelemente durch mindestens ein Verbindungsmittel mit dem Basiselement verbunden werden.For example, a plank, screed, plank or strip as cover elements can have a recess on at least one, but preferably on both sides, which extends over the entire length of the plank, plank, plank or strip. This element can thus be flexibly positioned on the base element (preferably a profile carrier), since the entire length is available for the connection with the connecting means according to the invention. Both side surfaces are expediently provided with cutouts. A whole area can be laid out with the planks, planks, planks or strips using the connecting means, two cover elements each being connected to the base element by at least one connecting means.

In dieser Ausführungsform kann das Verbindungsmittel insbesondere zur Erstellung von Beplankungen im Bereich von Sonnendächern, Terrassen, Badezimmern, Badebereichen oder um Schwimmbecken verwendet werden.In this embodiment, the connecting means can be used in particular to create planking in the area of sun roofs, terraces, bathrooms, bathing areas or around swimming pools.

Das erfindungsgemäße Verbindungsmittel ist insbesondere bei ersten Elementen mit seitlich sich erstreckender Aussparung von Vorteil. Durch den Drehschluss ergibt sich ein Verbindungsmittel mit definierter Dicke im mittleren Bereich, der dann den Abstand der ersten Elemente vorgibt. Auf diese Weise können die ersten Elemente sehr exakt verlegt werden, indem sie durch das Verbindungsmittel parallel zueinander mit definiertem Abstand angeordnet werden.The connecting means according to the invention is particularly advantageous in the case of first elements with a laterally extending recess. The rotational connection results in a connecting means with a defined thickness in the central area, which then specifies the distance between the first elements. In this way, the first elements can be laid very precisely by being arranged parallel to one another at a defined distance by the connecting means.

Der Fachmann erhält hiermit die Möglichkeit durch einfache Abänderung der Geometrie des mittleren Bereiches den Abstand der zu verlegenden ersten Elemente zu steuern. Da dieser mittlere Bereich nicht unmittelbar an der Verbindung von dem mindestens einen ersten Element mit dem Basiselement beteiligt ist, kann er, ohne das Basiselement oder das erste Element ändern zu müssen, eine Vielzahl von Verbindungsmitteln bereitstellen, die es erlauben, den ihm gewünschten Abstand einfach und reproduzierbar einzustellen.The person skilled in the art hereby has the possibility of controlling the distance of the first elements to be installed by simply changing the geometry of the central region. Since this central region is not directly involved in the connection of the at least one first element to the base element, it can, without having to change the base element or the first element, provide a large number of connection means which allow the desired distance to be simply achieved and adjust reproducible.

Durch den definierten, den Drehschluss resultierenden Winkel kann auch die Orientierung von den ersten Elementen zu dem einen oder mehreren Basiselementen festgelegt werden.Due to the defined angle resulting from the twist connection, the orientation from the first elements to the one or more basic elements can also be determined.

In einer Ausführungsform der Erfindung beträgt der definierte Winkel weniger als 360° und ist bevorzugt kleiner gleich 180° und besonders bevorzugt kleiner gleich 90°.In one embodiment of the invention, the defined angle is less than 360 ° and is preferably less than or equal to 180 ° and particularly preferably less than or equal to 90 °.

In einer bevorzugten Ausführungsform steht hierbei das mindestens eine erste Element, das bevorzugt eine Planke oder Bohle ist, senkrecht zu dem Basiselement, welches bevorzugt ein Profilträger oder eine Profilleiste ist.In a preferred embodiment, the at least one first element, which is preferably a plank or screed, is perpendicular to the base element, which is preferably a profile carrier or a profile strip.

In einer alternativen Ausführungsform steht das mindestens eine erste Element in einem Winkel von 45° zu dem Basiselement, welches bevorzugt ein Profilträger oder eine Profilleiste ist.In an alternative embodiment, the at least one first element is at an angle of 45 ° to the base element, which is preferably a profile carrier or a profile strip.

Die Ausgestaltung der Aussparung des mindestens einen ersten Elementes über einen breiten Bereich des ersten Elementes hat auch den Vorteil, dass dieses Element mit Hilfe von mehreren Verbindungsmitteln an das Basiselement befestigt werden kann. So kann beispielweise eine Planke als Deckelement mit mehreren Basiselementen, bevorzugt in Form von Profiträgern, verbunden werden.The design of the recess of the at least one first element over a wide area of the first element also has the advantage that this element can be fastened to the base element with the aid of several connecting means. For example, a plank can be connected as a cover element to several base elements, preferably in the form of professional supports.

In einer besonderen Ausführungsform weist die Aussparung einen dreieckigen Querschnitt auf und ist bevorzugt als gleichseitiges Dreieck ausgestaltet. Die Ausformung mit einem dreieckigen Querschnitt erlaubt zumindest für eine Seite einen formschlüssigen Kontakt mit der nach oben abgeschrägten Fläche des vorspringenden Verbindungsteils im oberen Bereich des Verbindungsmittels.In a special embodiment, the recess has a triangular cross section and is preferably designed as an equilateral triangle. The shape with a triangular cross section allows positive contact with the upwardly sloping surface of the projecting connecting part in the upper region of the connecting means at least for one side.

In einer bevorzugten Ausführungsform ist das Verbindungsmittel im oberen Bereich so gestaltet, dass es hier die Aussparung nicht komplett ausfüllt und so beispielsweise Platz für ein Verschlussmittel, wie eine Schraube verbleibt. Hierbei kann das Verbindungsmittel in einer Ausführungsform einen trapezoiden Querschnitt aufweisen. Bevorzugt ist hier eine Ausformung mit einer oberen horizontalen Basis und zwei nach oben abgeschrägten Seitenflächen. (s. Figur 1).In a preferred embodiment, the connecting means in the upper region is designed in such a way that it does not completely fill the recess here and so, for example, there is space for a locking means such as a screw. In one embodiment, the connecting means can have a trapezoidal cross section. A shape with an upper horizontal base and two upwardly sloping side surfaces is preferred here. (S. Figure 1 ).

In einer weiteren Ausführungsform wird mindestens ein erstes Element mit einer dreieckigen Nut kombiniert mit einem dreieckig ausgestalteten vorspringenden Verbindungsteil im oberen Bereich des Verbindungsmittels, da hierdurch eine beidseitig formschlüssige Verbindung erfolgt.In a further embodiment, at least a first element with a triangular groove is combined with a triangular projecting Connecting part in the upper area of the connecting means, since this creates a positive connection on both sides.

In einer bevorzugten Ausführungsform der Erfindung ist das Basiselement als Profilträger und besonders bevorzugt als Profilleiste ausgestaltet. Diese Profilleiste ist bevorzugt ein C-Profil mit nach innen weisenden Stegen oder mit trapezförmiger Aussparung.In a preferred embodiment of the invention, the base element is designed as a profile carrier and particularly preferably as a profile strip. This profile strip is preferably a C-profile with webs pointing inwards or with a trapezoidal recess.

Besonders bevorzugt ist hier trapezförmige Aussparung, die auch als Schwalbenschwanz-Nut bezeichnet werden kann. Sie erlaubt in Verbindung mit einer komplementären Trapezform des Verbindungsmittels im unteren Bereich eine besonders feste Verbindung von erstem Element mit Basiselement.Trapezoidal recess, which can also be referred to as a dovetail groove, is particularly preferred here. In conjunction with a complementary trapezoidal shape of the connecting means in the lower area, it allows a particularly firm connection of the first element with the base element.

Das Verbindungsmittel kann zweckmäßigerweise aus jedem Material hergestellt werden, das der Fachmann für Verbindungsmittel verwendet.The connecting means can expediently be produced from any material which the person skilled in the art uses for connecting means.

Das Verbindungsmittel kann entsprechend aus Kunststoff, Metall, Holz oder einem Holzverbundstoff bestehen, wobei Kunststoff bevorzugt ist. Kunststoffe weisen nicht nur eine hohe Korrosionsbeständigkeit bzw. chemische Beständigkeit auf, sondern sie zeigen auch eine gewisse Flexibilität die das Eindrehen des Verbindungsmittels in das Basiselement erleichtert.The connecting means can accordingly consist of plastic, metal, wood or a wood composite, plastic being preferred. Plastics not only have a high level of corrosion resistance or chemical resistance, but they also show a certain flexibility that makes it easier to screw the connecting means into the base element.

In einer bevorzugten Ausführungsform besteht das Verbindungsmittel aus einem Kunststoff, der ausgewählt ist aus der Gruppe enthaltend Polyethylen, Polyamid, Polypropylen, Polyester, PET, Polymethylmethacrylat (PMMA), Polyurethan, Polyvinylchlorid, ausgehärtete Epoxidharze und Polystyrol.In a preferred embodiment, the connecting means consists of a plastic which is selected from the group comprising polyethylene, polyamide, polypropylene, polyester, PET, polymethyl methacrylate (PMMA), polyurethane, polyvinyl chloride, hardened epoxy resins and polystyrene.

Besonders bevorzugt ist hierbei Polyamid als Kunststoff.Polyamide is particularly preferred as the plastic.

Um besonders zugfeste Verbindungsmittel zu erhalten, ist es vorteilhaft, dass das Verbindungsmittel aus einem Faser-verstärkten Kunststoff besteht, wobei die Fasern bevorzugt aus der Gruppe ausgewählt sind, bestehend aus Basaltfasern, Borfasern, Glasfasern, Keramikfasern, Kieselsäurefasern, Stahl-Fasern, Aramidfasern, Kohlenstofffasern, Polyester-Fasern, Nylon-Fasern, Polyethylen-Fasern und Plexiglas-Fasern.In order to obtain particularly high-tensile fasteners, it is advantageous that the fastener consists of a fiber-reinforced plastic, the fibers preferably being selected from the group consisting of basalt fibers, boron fibers, glass fibers, ceramic fibers, silica fibers, steel fibers, aramid fibers, Carbon fibers, polyester fibers, nylon fibers, polyethylene fibers and plexiglass fibers.

Besonders bevorzugt ist hierbei die Verwendung von Glasfasern, wobei im Speziellen ein Glasfaser-verstärktes Polyamid oder ein Faser-verstärktes Epoxidharz bevorzugt ist.The use of glass fibers is particularly preferred, a glass fiber-reinforced polyamide or a fiber-reinforced epoxy resin being particularly preferred.

In einer weiteren Ausführungsform ist das Verbindungsmittel aus einem transparenten Kunststoff gestaltet, so dass es gerade bei größeren Abständen zwischen den ersten Elementen nicht optisch in Erscheinung tritt und der Verbindung ein einheitliches Erscheinungsbild verleiht.In a further embodiment, the connecting means is made of a transparent plastic, so that it does not appear optically, especially when there are larger distances between the first elements, and gives the connection a uniform appearance.

Das erfindungsgemäße Verbindungsmittel kann auch aus verschiedenen Materialien aufgebaut sein. Bevorzugt ist hier, dass hierbei die einzelnen Bereiche aus einem unterschiedlichen Material bestehen. So kann bespielweise der untere und mittlere Bereich aus Kunststoff bestehen und der obere Bereich aus Metall aufgebaut sein. Als Materialien kommen hierbei alle oben genannten Materialien in Frage.The connecting means according to the invention can also be constructed from different materials. It is preferred here that the individual areas consist of a different material. For example, the lower and middle area can be made of plastic and the upper area can be made of metal. All materials mentioned above can be used as materials.

In einer weiteren Ausführungsform der Erfindung weist das Verbindungsmittel eine von oben nach unten verlaufende Bohrung auf, die bevorzugt durchgehend ist.In a further embodiment of the invention, the connecting means has a bore which runs from top to bottom and which is preferably continuous.

Auch wenn erfindungsgemäß durch die alleinige Drehung des Verbindungsmittels eine Verbindung zwischen erstem Element und Basiselement hergestellt wird, kann diese Bohrung dazu verwendet werden, ein zusätzliches Befestigungselement wie beispielsweise eine Schraube, ein Nagel, ein Bolzen oder eine Niete einzuführen, um die Verbindung noch weiter zu stärken.Even if, according to the invention, a connection between the first element and the base element is established by the sole rotation of the connecting means, this hole can be used to insert an additional fastening element such as a screw, a nail, a bolt or a rivet in order to further tighten the connection strengthen.

Zweckmäßigerweise weist das Verbindungsmittel im oberen Bereich ein Mitnahmeprofil auf, das ausgewählt ist aus der Gruppe enthaltend Schlitz, Kreuzschlitz, Inbus, Sechskanteinbuchtung oder-kopf, Innen-Torx oder Außen-Torx, Phillips-Schraubenprofil, Pozidriv, Torq Set, Mortorq, Tri-Wing, und Robertson-Schraubenprofil, wobei das Mitnahmeprofil bevorzugt in der Bohrung ausgeformt ist.The connecting means expediently has a driving profile in the upper region, which is selected from the group consisting of slot, cross recess, hex, hexagonal indentation or head, inner torx or outer torx, Phillips screw profile, Pozidriv, Torq Set, Mortorq, Tri- Wing, and Robertson screw profile, the driving profile is preferably formed in the bore.

Ein in der Bohrung ausgeformtes Mitnahmeprofil besitzt den Vorteil der leichten Zugänglichkeit. Dies erlaubt es, selbst im verbauten Zustand das Verbindungsmittel zu lösen. So kann bei dem bevorzugten Einsatz für die Verlegung von Terassenplanken auf einem Trägerprofil das Mitnahmewerkzeug durch die Lücken zwischen den Planken eingreifen und durch einfache Drehung die Verbindung lösen. Dies hat den entscheidenden Vorteil, dass die Terassenplanken nicht von der Seite her abgedeckt werden müssen, um ein schadhaftes in der Mitte befindliches Planke auszutauschen, sondern es kann gezielt eine mittig positionierte Planke ausgetauscht werden.A driving profile formed in the bore has the advantage of easy accessibility. This allows the connecting means to be released even when installed. In the preferred application for laying terrace planks on a support profile, the driving tool can intervene through the gaps between the planks and detach the connection by simple rotation. This has the decisive advantage that the terrace planks do not have to be covered from the side in order to replace a defective plank in the middle, but instead a centrally positioned plank can be replaced.

In einer weiteren Ausführungsform stellt der obere Bereich mit seinem rechteckigen Profil selber das Mitnahmeprofil bereit, so dass er mit einem entsprechenden Werkzeug wie beispielsweise einer Zange, einem Maulschlüssel oder einem verstellbaren Maulschlüssel (Franzose oder Engländer) gedreht werden kann.In a further embodiment, the upper area with its rectangular profile itself provides the entrainment profile so that it can be rotated with an appropriate tool, such as pliers, an open-end wrench or an adjustable open-end wrench (French or English).

In einem weiteren Aspekt stellt die Erfindung ein Verfahren zur Verbindung von mindestens einem Brett oder einer Planke zu einem Trägerprofil bereit, dass dadurch gekennzeichnet ist, dass das Verbindungsmittel in die Vertiefung des Basiselementes eingeführt wird und unter Anliegen des mindestens einen ersten Elements um den definierten Winkel bis zur Arretierung gedreht wird, so dass das mindestens eine erste Element mit dem Basiselement verbunden wird.In a further aspect, the invention provides a method for connecting at least one board or a plank to a support profile, which is characterized in that the connecting means is inserted into the recess of the base element and in contact with the at least one first element by the defined angle is rotated until it locks, so that the at least one first element is connected to the base element.

In einer weiteren Ausführungsform werden bei dem Verfahren zwei erste Elemente angelegt, wobei das Verbindungsmittel zwischen den beiden ersten Elementen positioniert ist, und durch die Drehung um den definierten Winkel bis zur Arretierung beide erste Elemente mit dem Basiselement verbinden.In a further embodiment, two first elements are created in the method, the connecting means being positioned between the two first elements, and connecting the first two elements to the base element by rotation through the defined angle until locking.

Entsprechend kann das Verfahren auch mit drei, vier, fünf, sechs, sieben, acht, neun, zehn oder sogar mehr ersten Elementen durchgeführt werden, wobei das Verbindungsmittel dann an den Kreuzungspunkten dieser ersten Elemente zu liegen kommt.Correspondingly, the method can also be carried out with three, four, five, six, seven, eight, nine, ten or even more first elements, the connecting means then coming to lie at the points of intersection of these first elements.

In einer bevorzugten Ausführungsform weist bei dem Verfahren das Verbindungsmittel im oberen Bereich zwei entgegengesetzt positionierte vorspringende Verbindungsteile auf und der definierte Winkel bis zur Arretierung beträgt 90°.In a preferred embodiment, the connecting means in the method has two oppositely positioned projecting connecting parts in the upper region and the defined angle up to the locking is 90 °.

In einem weiteren Aspekt betrifft die Erfindung auch die Verwendung des erfindungsgemäßen Verbindungselements zur Verwendung in einem wie oben beschriebenen Verfahren.In a further aspect, the invention also relates to the use of the connecting element according to the invention for use in a method as described above.

Die Erfindung ist in den Zeichnungen in mehreren Ausführungsbeispielen dargestellt und nachfolgend beschrieben.The invention is shown in the drawings in several exemplary embodiments and described below.
