Description

Die Erfindung betrifft ein Befestigungselement zum Befestigen zweier Sichtprofile, insbesondere Terrassenprofile, an einer Unterkonstruktion, mit einer Platte, die zum Eingreifen in gegenüberliegende Nuten an den zugewandten Profillängsseiten der Sichtprofile ausgebildet ist, mit mindestens einer in der Platte ausgesparten Montageöffnung für Befestigungsmittel, mit mindestens einer in die Platte eingebrachten Erhebung zum Festklemmen der Platte in mindestens einer Nut der Sichtprofile, wobei die Erhebung einen Haken an der Platte ausbildet, und mit einem, insbesondere mittig, an der Platte angeordneten und von der Platte geneigt abstehenden Abstandshalter, wobei Abstandshalter und Erhebung von gegenüberliegenden Plattenbreitseiten weg abstehen, wobei der Abstandshalter an einer Plattenstirnseite der Platte angeordnet ist.The invention relates to a fastening element for fastening two visible profiles, in particular terrace profiles, to a substructure, with a plate which is designed to engage in opposite grooves on the facing longitudinal sides of the visible profiles, with at least one mounting opening for fastening means which is recessed in the plate, with at least one introduced into the plate elevation for clamping the plate in at least one groove of the viewing profiles, the elevation forming a hook on the plate, and with a spacer, in particular in the center, arranged on the plate and protruding from the plate, spacers and elevation of protrude from opposite plate broadsides, the spacer being arranged on a plate end face of the plate.

Eine Befestigungselement zum Befestigen zweier Terrassenprofile an einer Unterkonstruktion ist aus der DE 202004 017477 U1 bekannt. Das Befestigungselement greift zwischen gegenüberliegende Nuten an den zugewanderten Profillängsseiten der Sichtprofile ein und klemmt über eine in der Unterkonstruktion verankerten Holzschraube die Sichtprofile auf die Unterkonstruktion. Hierzu weist die Platte des Befestigungselements ausgesparte Montageöffnung auf, welche von einer Holzschraube als Befestigungsmittel durchgriffen wird. Zur Montagerleichterung sind an der Platte eingeprägte kreisförmige Erhebungen vorgesehen, über welche die Platte in einer Nut der Sichtprofile festgesetzt werden kann. Die klemmende Funktion derartiger Erhebungen ist jedoch vergleichsweise empfindlich gegenüber Maßtoleranzen an der Nut der Sichtprofile - was die Handhabung der Platte erschwert.A fastening element for fastening two terrace profiles to a substructure is from the DE 202004 017477 U1 known. The fastening element engages between opposing grooves on the immigrated profile long sides of the view profiles and clamps the view profiles onto the substructure via a wood screw anchored in the substructure. For this purpose, the plate of the fastening element has a recessed mounting opening which is penetrated by a wood screw as a fastening means. In order to facilitate assembly, circular elevations are provided on the plate, by means of which the plate can be fixed in a groove in the viewing profiles. The clamping function of such elevations is, however, comparatively sensitive to dimensional tolerances in the groove of the viewing profiles - which complicates the handling of the plate.

Ein Befestigungselement nach dem Oberbegriff des Anspruchs 1 ist aus der US2014/0021236A1 bekannt. Dieses Befestigungselement weist zum Unterschied zu eingeprägten Erhebungen zwei Erhebungen auf, die je einen Haken an der Platte ausbilden. Die Haken sind einander gegenläufig ausgerichtet. Zudem weist dieses Befestigungselement zwei von der Plattenlängsseite geneigt abstehenden Abstandshalter, wobei Abstandshalter und Erhebung von gegenüberliegenden Plattenbreitseiten weg abstehen.A fastener according to the preamble of claim 1 is from the US2014 / 0021236A1 known. In contrast to embossed elevations, this fastening element has two elevations, each of which forms a hook on the plate. The hooks are aligned in opposite directions. This also indicates Fastening element two spacers projecting at an angle from the long side of the panel, the spacer and elevation projecting away from opposite broad sides of the panel.

Die Erfindung hat sich die Aufgabe gestellt, eine Alternative zu dem bekannten Befestigungselement vorzuschlagen, das einfach und kostengünstig herstellbar ist.The invention has set itself the task of proposing an alternative to the known fastener that is simple and inexpensive to manufacture.

Die Erfindung löst die gestellte Aufgabe durch die Merkmale des Anspruchs 1.The invention solves this problem by the features of claim 1.

Ist die Erhebung durch Einschneiden und Formbiegen eines zungenförmigen Abschnitts aus der aus einem Metallblech hergestellten Platte gebildet, kann solch eine Erhebung mit Hilfe bekannter Blechumformverfahren vergleichsweise prozesssicher und kostengünstig in der Platte vorgesehen werden. Außerdem ist durch das erfindungsgemäße Blechumformverfahren die Gefahr von Verformungen anderer Bereiche der Platte gering. Ein formgenaues und standfestes Befestigungselement kann damit sicherstellt werden.If the elevation is formed by cutting and shaping a tongue-shaped section from the plate made from a sheet metal, such elevation can be provided in the plate in a comparatively reliable and cost-effective manner using known sheet metal forming processes. In addition, the sheet metal forming process according to the invention minimizes the risk of deformation of other areas of the plate. A precise and stable fastener can be ensured.

Das Befestigungselement kann zudem zur Einstellung des Spalts zwischen ihren beiden angrenzenden Sichtprofilen genutzt werden, wenn der Abstandshalter an einer Plattenstirnseite der Platte angeordneten ist. Im Zusammenwirken mit der Erhebung, kann so das Befestigungselement in der Nut eines Sichtprofils besonders standfest positioniert bzw. dadurch auch ausgerichtet werden. Dies stellt eine standfeste Befestigung der Sichtprofile sicher.The fastening element can also be used to adjust the gap between its two adjacent viewing profiles if the spacer is arranged on a plate face of the plate. In cooperation with the elevation, the fastening element can thus be positioned in a particularly stable manner in the groove of a visible profile or can also be aligned thereby. This ensures a stable attachment of the visible profiles.

Das Befestigungselement kann daher nicht nur vergleichsweise kostengünstig gefertigt werden, sondern auch eine hohe Funktionssicherheit aufweisen.The fastening element can therefore not only be manufactured comparatively inexpensively, but also have a high level of functional reliability.

Die Wirkung der Erhebung kann weiter erhöht werden, wenn der Verlauf des zungenförmigen Abschnitts von der ersten zur zweiten Plattenlängsseite gerichtet ist. Insbesondere kann damit das Abziehen des Befestigungselements aus der Nut erschwert und damit die Position des Befestigungselements am Sichtprofil gesichert werden.The effect of the elevation can be further increased if the course of the tongue-shaped section is directed from the first to the second longitudinal side of the plate. In particular, this can make it difficult to pull the fastening element out of the groove and thus secure the position of the fastening element on the visible profile.

Ist der Zungengrund des zungenförmigen Abschnitts an der Platte außermittig angeordnet, kann die Erhebung tiefer in die Nut eines jeweiligen Sichtprofils eingeführt werden. Damit kann es möglich werden, dass die Platte dem Verlauf der Nut parallel folgt und auch das Festsitzen der Platte in der Nut verbessert wird. Des Weiteren kann dadurch sichergestellt werden, dass der zungenförmige Abschnitt verlässlich vom Sichtprofil verdeckt wird - und das Befestigungselement für unterschiedlich ausgestaltete Sichtprofile eingesetzt werden kann. Die Handhabungsfreundlichkeit und Verwendungsmöglichkeiten des Befestigungselements ist damit weiter erhöhbar.If the base of the tongue of the tongue-shaped section is arranged off-center on the plate, the elevation can be inserted deeper into the groove of a respective visible profile. This can make it possible for the plate to follow the course of the groove in parallel and for the plate to become stuck in the groove. Furthermore, it can be ensured that the tongue-shaped section is reliably covered by the view profile - and that the fastening element can be used for differently designed view profiles. The ease of use and possible uses of the fastener can thus be further increased.

Verläuft die Längskante des freien Endes des zungenförmigen Abschnitts parallel zu einer Plattenlängsseite, kann die festkrallende Wirkung des Hakens in der Nut breiter verteilt wirken - und damit Maßtoleranzen robuster gegenüberstehen. Zudem vermeidet diese parallele Ausrichtung spitz zulaufende Kanten, was unter anderem auch eine Verletzungsgefahr am Befestigungselement reduzieren kann. Das erfindungsgemäße Befestigungselement ist auf diese Weise in seiner Handhabung und Funktion vergleichsweise sicher.If the longitudinal edge of the free end of the tongue-shaped section runs parallel to a long side of the panel, the clawing effect of the hook in the groove can appear to be more widespread - and thus more tolerant of dimensional tolerances. In addition, this parallel alignment avoids tapered edges, which among other things can reduce the risk of injury to the fastener. The fastening element according to the invention is comparatively safe in its handling and function in this way.

Die Wirkung der Erhebung ist weiter erhöhbar, wenn der zungenförmige Abschnitt parallel zu einer Plattenlängsseite verläuft. Insbesondere kann sich damit ein Verschieben des Befestigungselements in der Nut erschweren - und damit die Position des Befestigungselements am Sichtprofil gesichert werden.The effect of the elevation can be increased further if the tongue-shaped section runs parallel to a longitudinal side of the plate. In particular, this can make it difficult to move the fastening element in the groove - and thus secure the position of the fastening element on the visible profile.

Dieses Verschieben kann zudem in beide Längsrichtungen der Nut erschwert werden, wenn die Platte mehrere, je als zungenförmiger Abschnitt ausgebildete Erhebungen aufweist, die einander gegenläufig ausgerichtet sind.This displacement can also be made more difficult in both longitudinal directions of the groove if the plate has a plurality of elevations, each designed as a tongue-shaped section, which are aligned in opposite directions.

Verläuft die Längskante des freien Endes des zungenförmigen Abschnitts parallel zu einer Plattenstirnseite, kann die festkrallende Wirkung des Hakens in der Nut breiter verteilt wirken - und damit Maßtoleranzen robuster gegenüberstehen.If the longitudinal edge of the free end of the tongue-shaped section runs parallel to a face of the panel, the clawing effect of the hook in the groove can appear to be more widespread - and thus the dimensional tolerances are more robust.

Die Klemmwirkung der Befestigungselements kann verstärkt werden, wenn die Platte mehrere Erhebungen aufweist. Sind zudem die Zungengründe der zungenförmigen Abschnitte der Erhebungen lediglich an einer Plattenlängsseite angeordnet, kann dies die Handhabung des Befestigungselements erleichtern. So ist es in diesem Fall etwa ermöglicht, dass die von Erhebungen freie Plattenlängsseite ein Spiel in der anderen Nut des Sichtprofils erlaubt.The clamping effect of the fastening element can be increased if the plate has several elevations. In addition, if the tongue bases of the tongue-shaped sections of the elevations are arranged only on one longitudinal side of the plate, this can facilitate the handling of the fastening element. In this case, for example, it is possible for the long side of the panel free of elevations to allow play in the other groove of the viewing profile.

Vorstehende Wirkung des Abstandshalters kann besonders variabel sein, wenn dieser Abstandshalter U-förmig ausgebildet ist - und zwar durch die entsprechende Neigung der Schenkel des Abstandshalters.The protruding effect of the spacer can be particularly variable if this spacer is U-shaped - specifically by the corresponding inclination of the legs of the spacer.

Solch ein Abstandshalter kann durch ein Blechumformverfahren auf einfache und kostengünstige Weise an der Platte erzeugt werden, wenn dieser Abstandshalter durch Einschneiden und Zusammenbiegen zweier Stege aus der Platte gebildet ist.Such a spacer can be produced on the plate in a simple and inexpensive manner by a sheet metal forming process if this spacer is formed by cutting and bending two webs out of the plate.

Ist die Montageöffnung zentrisch an der Platte vorgesehen, kann dies ein Einsetzen eines Befestigungsmittels aufgrund des sich zwischen den Sichtprofilen ergebenden Spalts erleichtern. Die Handhabung der Platte kann dadurch weiter erleichtert werden.If the mounting opening is provided centrally on the plate, this can make it easier to insert a fastening means due to the gap that results between the viewing profiles. This further facilitates the handling of the plate.

Das erfindungsgemäße Befestigungselement findet bevorzug bei einem Terrassensystem mit mehreren Sichtprofilen und mit einer Unterkonstruktion Verwendung. Das Befestigungselement greift mit der Platte in die Nuten der Sichtprofile ein. Vorzugsweise verklemmt die Erhebung das Befestigungselement in der Nut.The fastening element according to the invention is preferably used in a terrace system with several viewing profiles and with a substructure. The fastener engages with the plate in the grooves of the viewing profiles. The elevation preferably jams the fastening element in the groove.

Im Allgemeinen erwähnt, dass sich die Erfindung besonders für Sichtprofile eignen kann, die einen Holzwerkstoff aufweisen. Bei derartigen Sichtprofilen kann die witterungsbedingte Gefahr einer Schwindung vergleichsweise hoch sein. Vorzugsweise sind die Sichtprofile als Vollprofil ausgeführt und bestehen beispielsweise aus Holz.Generally mentioned that the invention can be particularly suitable for visible profiles that have a wood material. With such viewing profiles, the weather-related risk of shrinkage may be comparatively high. The visible profiles are preferably designed as full profiles and consist, for example, of wood.

Nach Fig. 1 wird in einer Seitenansicht beispielsweise ein Terrassensystem 1 dargestellt, bei dem mit Hilfe eines Befestigungselements 2a als erstem Ausführungsbeispiel zwei als Terrassenprofile ausgeführte Sichtprofile 3, 4 an eine Unterkonstruktion 5 geklemmt und damit an dieser Unterkonstruktion 5 befestigt werden. Die Sichtprofile 3, 4 weisen ein Vollholzprofil auf und sind vorzugsweise als Dielen ausgebildet.To Fig. 1 For example, a side view of a terrace system 1 is shown in which, with the aid of a fastening element 2a as the first exemplary embodiment, two viewing profiles 3, 4 designed as terrace profiles are clamped to a substructure 5 and are thus fastened to this substructure 5. The visible profiles 3, 4 have a solid wood profile and are preferably designed as planks.

Die Klemmkraft wird von einem als Holzschraube ausgeführten Befestigungsmittel 7 erzeugt, das die Platte 2 des Befestigungselements 2a an einer ausgesparten zentrischen Montageöffnung 6 durchgreift und die sich in der Unterkonstruktion 5 verankert.The clamping force is generated by a fastening means 7 designed as a wood screw, which passes through the plate 2 of the fastening element 2a at a recessed central mounting opening 6 and which is anchored in the substructure 5.

Die Platte 2 des Befestigungselements 2a greift in die gegenüberliegenden Nuten 8, 9 an den einander zugewanderten Profillängsseiten 3.1, 4.1 der Sichtprofile 3, 4 ein. Diese Platte 2 weist mehrere Erhebungen 10 auf, die auf einer gemeinsamen Plattenbereitseite 2.1 vorspringen - wie dies in der Fig. 2 besser erkannt werden kann. Über diese beiden Erhebungen 10 wird die Platte 2 in der Nut 8 des ersten Sichtprofils 3 mit einer bestimmten Haltekraft festgeklemmt. Genauso vorstellbar ist jedoch, dass die Platte 2 Erhebungen für beide Nuten 8, 9 der Profillängsseiten 3.1, 4.1 aufweist.The plate 2 of the fastening element 2a engages in the opposite grooves 8, 9 on the longitudinal profile sides 3.1, 4.1 of the view profiles 3, 4 which have migrated towards one another. This plate 2 has several elevations 10 which project on a common plate ready side 2.1 - as is the case in FIG Fig. 2 can be better recognized. About these two elevations 10, the plate 2 in the groove 8 of the first viewing profile 3 clamped with a certain holding force. However, it is equally conceivable that the plate 2 has elevations for both grooves 8, 9 of the longitudinal sides 3.1, 4.1.

Diese Haltekraft wird besonders dadurch verstärkt, dass die Erhebungen 10 je von einem zungenförmigen Abschnitt 11.1, 11.2 bzw. 111.1, 111.2 gebildet werden, welcher zungenförmige Abschnitt 11.1, 11.2 je einen Haken 12.1, 12.2 an der Platte 2 ausbilden. Nach dem Einbringen der Platte 2 in die erste Nut 8 verkrallen sich die Erhebungen 10 im Material des ersten Sichtprofils 3, wenn das Sichtprofil 3 von der Platte weggezogen oder die Platte 2 aus der ersten Nut 8 herausgezogen wird. Das Befestigungselement 2a wird also standfest in der ersten Nut 8 geklemmt - womit bei der Montage des Terrassensystems 1 bzw. in dessen Montagezustand ein unbeabsichtigtes Lösen des ersten Sichtprofils 3 vermieden wird. Außerdem kann damit das Befestigungselement 2a gegenüber Maßtoleranzen an der Nut 8 des Sichtprofils 3 robust ausgebildet werden. Das erfindungsgemäße Befestigungselement 2a kann daher nicht nur vergleichsweise kostengünstig gefertigt werden, sondern weist auch eine hohe Funktionssicherheit auf.This holding force is particularly enhanced by the fact that the elevations 10 are each formed by a tongue-shaped section 11.1, 11.2 or 111.1, 111.2, which tongue-shaped section 11.1, 11.2 each form a hook 12.1, 12.2 on the plate 2. After the plate 2 has been introduced into the first groove 8, the elevations 10 cling to the material of the first visible profile 3 when the visible profile 3 is pulled away from the plate or the plate 2 is pulled out of the first groove 8. The fastening element 2a is thus clamped in a stable manner in the first groove 8 - which prevents the unintentional loosening of the first viewing profile 3 when the terrace system 1 is being assembled or in its assembled state. In addition, the fastening element 2 a can be designed to be robust with respect to dimensional tolerances on the groove 8 of the viewing profile 3. The fastening element 2a according to the invention can therefore not only be manufactured comparatively inexpensively, but also has a high degree of functional reliability.

Kostengünstig und dennoch formgenau wird der zungenförmigen Abschnitt 11.1, 11.2 bzw. 111.1, 111.2 durch Einschneiden und Formbiegen aus der aus einem Metallblech, insbesondere Stahlblech, vorzugsweise Edelstahlblech, hergestellten Platte 2 gebildet.The tongue-shaped section 11.1, 11.2 or 111.1, 111.2 is formed in a cost-effective and yet precise manner by cutting and shaping from the plate 2 produced from a metal sheet, in particular steel sheet, preferably stainless steel sheet.

Die zungenförmigen Abschnitte 11.1, 11.2 verlaufen im rechten Winkel von einer ersten Plattenlängsseite 2.2 weg zur zweiten Plattenlängsseite 2.3.The tongue-shaped sections 11.1, 11.2 run at right angles from a first longitudinal side 2.2 of the plate to the second longitudinal side 2.3.

Die Zungengründe 13.1, 13.2 der zungenförmigen Abschnitte 11.1, 11.2 sind an der Platte 2 außermittig und lediglich an der ersten Plattenlängsseite 2.2 angeordnet, was die Klemmkraft der Erhebungen 10 mit der ersten Nut 8 des ersten Sichtprofils 3 verstärkt und die Ausrichtung der Platte 2 am Sichtprofil 3 des Terrassensystems 1 sichert.The tongue bases 13.1, 13.2 of the tongue-shaped sections 11.1, 11.2 are arranged off-center on the plate 2 and only on the first longitudinal side 2.2 of the plate, which increases the clamping force of the elevations 10 with the first groove 8 of the first visible profile 3 and the alignment of the plate 2 on the visible profile 3 of the terrace system 1 secures.

Die Längskanten 14.1, 14.2 der freien Enden 15.1, 15.2 der zungenförmigen Abschnitte 11.1, 11.2 verlaufen jeweils parallel zur den Plattenlängsseite 2.2, 2.3, womit aufgrund der größeren Angriffsfläche der freien Enden 15.1, 15.2 ein verbessertes Halten des Sichtprofils 3 gewährleistet wird. Zudem wird damit bei der Handhabung des Befestigungselements 2a die Verletzungsgefahr an den Haken 12.1, 12.2 verringert.The longitudinal edges 14.1, 14.2 of the free ends 15.1, 15.2 of the tongue-shaped sections 11.1, 11.2 each run parallel to the longitudinal side 2.2, 2.3 of the plate, which, due to the larger contact surface of the free ends 15.1, 15.2, ensures improved retention of the viewing profile 3. In addition, the risk of injury to the hooks 12.1, 12.2 is reduced when handling the fastening element 2a.

Des Weiteren weist die Platte 2 an beiden Plattenstirnseiten 2.4, 2.5 Abstandshalter 16, 17 auf, welche von Platte 2 geneigt abstehend und mittig der Plattenstirnseiten 2.4, 2.5 angeordnet sind.Furthermore, the plate 2 has spacers 16, 17 on both plate end faces 2.4, 2.5, which are inclined and protrude from plate 2 and are arranged in the center of the plate end faces 2.4, 2.5.

Die beiden Abstandshalter 16, 17 dienen zum Einstellen eines Spalts 18 zwischen den beiden Sichtprofilen 3, 4. Die Abstandshalter 16, 17 werden durch Einschneiden und Zusammenbiegen zweier Stege 16.1, 16.2 bzw. 17.1, 17.2 aus der Platte 2 gebildet und sind damit kostengünstig und genau herzustellen. Derart wird auch eine U-Form der beiden Abstandshalter 16, 17 erreicht, welche zur Ausbildung der Größe dieses Spalts genutzt werden kann. Jeder Steg bildet für die jeweilige Profilschmalseite 3.1, 4.1 der Sichtprofilen 3, 4 eine Anschlagfläche 19 aus, wie diese in der Fig. 1 anhand des Abstandshalters 16 beispielsweise zu erkennen ist.The two spacers 16, 17 are used to set a gap 18 between the two viewing profiles 3, 4. The spacers 16, 17 are formed by cutting and bending two webs 16.1, 16.2 and 17.1, 17.2 from the plate 2 and are therefore inexpensive and to manufacture exactly. In this way, a U-shape of the two spacers 16, 17 is achieved, which can be used to form the size of this gap. Each web forms a stop surface 19 for the respective narrow profile side 3.1, 4.1 of the visible profiles 3, 4, as is shown in FIG Fig. 1 can be seen from the spacer 16, for example.

Außerdem stehen die Abstandshalter 16, 17 und die Erhebung 10 von gegenüberliegenden Plattenbreitseiten 2.1, 2.6 2 weg ab. Dies, indem die Erhebungen 10 der ersten Plattenbreitseite 2.1 und die Abstandshalter 16, 17 der zweiten Plattenbreitseiten 2.6 vorkragen. Damit kann der Abstandshalter 16, 17 bei Anschlag des Sichtprofils 4 ein durch Hebelkräfte verstärktes Verhaken des zungenförmigen Abschnitts 11.1 in der Nut 8 des jeweiligen anderen Sichtprofils 3 erleichtern.In addition, the spacers 16, 17 and the elevation 10 protrude away from opposite broad plate sides 2.1, 2.6 2. This is due to the fact that the elevations 10 of the first broad plate 2.1 and the spacers 16, 17 of the second broad plate 2.6 protrude. In this way, the spacer 16, 17 can facilitate the tongue-shaped section 11.1 becoming caught in the groove 8 of the respective other viewing profile 3 when the viewing profile 4 stops, which is reinforced by lever forces.

Wie insbesondere der Fig. 2 zu entnehmen, ist die Platte 2 rechteckig ausgebildet, was im Allgemeinen erwähnt wird. Zudem ist das Befestigungselement 2a quer zur Längserstreckung 20 der Platte 2, insbesondere durch die Montageöffnung 6, gesehen symmetrisch ausgebildet. Die Platte 2 kann zudem weitere Öffnungen 21 zur Führung von Stiften aufweisen - welche nicht dargestellten Stifte an der Unterkonstruktion 5 verankert sind.Like especially the Fig. 2 can be seen, the plate 2 is rectangular, which is generally mentioned. In addition, the fastening element 2a is formed symmetrically transverse to the longitudinal extension 20 of the plate 2, in particular through the mounting opening 6. The plate 2 can also further openings 21 for Guide of pins - which pins, not shown, are anchored to the substructure 5.

Nach der Figur 3 ist ein weiteres Terrassensystem 101 dargestellt. Dieses Terrassensystem 101 weist ein anders ausgeführtes Befestigungselement 2b als zweites Ausführungsbeispiel auf, was in Fig. 4 in einer Draufsicht dargestellt ist. Das Befestigungselement 2b unterscheidet sich vom Befestigungselement 2a nach den Figuren 1 und 2 im Wesentlichen durch eine andere konstruktive Ausführung der beiden Erhebungen 10.After Figure 3 Another terrace system 101 is shown. This terrace system 101 has a differently designed fastening element 2b as a second exemplary embodiment, which is shown in FIG Fig. 4 is shown in a plan view. The fastening element 2b differs from the fastening element 2a according to FIGS Figures 1 and 2 essentially by a different design of the two elevations 10.

Diese Erhebungen 10 werden je von einem zungenförmigen Abschnitt 111.1, 111.2 gebildet, die je einen Haken 12.1, 12.2 an der Platte 2 ausbilden, um das Befestigungselement 2b gegenüber einem Längsverschieben in der ersten Nut 8 des Sichtprofils 3 zu sichern. Hierzu verlaufen die zungenförmigen Abschnitte 111.1, 111.2 parallel zu einer Plattenlängsseite 2.1 bzw. 2.2, wie dies in der Fig. 4 erkannt werden kann. Daher verkrallen sich nach dem Einbringen der Platte 2 in die erste Nut 8 die Erhebungen 10 im Material des ersten Sichtprofils 3, wenn das Befestigungselement 2b oder Sichtprofil 3 entlang der ersten Nut 8 verschoben wird. Das Befestigungselement 2b wird also standfest in der ersten Nut 8 geklemmt - womit bei der Montage des Terrassensystems 101 bzw. in dessen Montagezustand ein unbeabsichtigtes Verschieben vermieden wird. Außerdem kann damit das Befestigungselement 2b gegenüber Maßtoleranzen an der Nut 8 des Sichtprofils 3 robust ausgebildet werden. Das erfindungsgemäße Befestigungselement 2b kann daher nicht nur vergleichsweise kostengünstig gefertigt werden, sondern weist auch eine hohe Funktionssicherheit auf.These elevations 10 are each formed by a tongue-shaped section 111.1, 111.2, which each form a hook 12.1, 12.2 on the plate 2 in order to secure the fastening element 2b against longitudinal displacement in the first groove 8 of the visible profile 3. For this purpose, the tongue-shaped sections 111.1, 111.2 run parallel to a longitudinal plate side 2.1 or 2.2, as shown in FIG Fig. 4 can be recognized. Therefore, after the plate 2 has been introduced into the first groove 8, the elevations 10 in the material of the first sight profile 3 become clawed when the fastening element 2b or sight profile 3 is displaced along the first groove 8. The fastening element 2b is thus clamped in a stable manner in the first groove 8, which prevents inadvertent displacement when the terrace system 101 is being assembled or in its assembled state. In addition, the fastening element 2b can be designed to be robust with respect to dimensional tolerances on the groove 8 of the visible profile 3. The fastening element 2b according to the invention can therefore not only be manufactured comparatively inexpensively, but also has a high degree of functional reliability.

Die Längskanten 114.1, 114.2 der freien Enden 115.1, 115.2 der zungenförmigen Abschnitte 111.1, 111.2 verlaufen jeweils parallel zu den parallelen Plattenstirnseiten 2.4, 2.5, womit aufgrund der größeren Angriffsfläche der freien Enden 15.1, 15.2 ein verbessertes Halten in der Nut 8 gewährleistet wird. Zudem wird damit bei der Handhabung des Befestigungselements 2b die Verletzungsgefahr an den Haken 12.1, 12.2 verringert.The longitudinal edges 114.1, 114.2 of the free ends 115.1, 115.2 of the tongue-shaped sections 111.1, 111.2 each run parallel to the parallel plate end faces 2.4, 2.5, which ensures improved hold in the groove 8 due to the larger contact surface of the free ends 15.1, 15.2. In addition, the Handling the fastener 2b reduces the risk of injury to the hooks 12.1, 12.2.

Die zungenförmigen Abschnitte 111.1, 111.2 sind zudem einander gegenläufig ausgerichtet, um richtungsunabhängig ein Längsverschieben des Befestigungselements 2b in der ersten Nut 8 zu unterbinden.The tongue-shaped sections 111.1, 111.2 are also aligned in opposite directions in order to prevent longitudinal movement of the fastening element 2b in the first groove 8 regardless of the direction.

Auch beim zweiten Befestigungselements 2b sind die Zungengründe 113.1, 113.2 der zungenförmigen Abschnitte 111.1, 111.2 der Erhebungen 10 lediglich an einer Plattenlängsseite 2.2 angeordnet und führen zu den gleichen Vorteilen, wie zum ersten Befestigungselements 2a beschrieben.In the case of the second fastening element 2b too, the tongue bases 113.1, 113.2 of the tongue-shaped sections 111.1, 111.2 of the elevations 10 are only arranged on a longitudinal side 2.2 of the plate and lead to the same advantages as described for the first fastening element 2a.
