Description

Die Erfindung betrifft eine in Löchern einer Wandleiste einrastbare Befestigungsvorrichtung entsprechend den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a fastening device which can be snapped into holes in a wall strip according to the features of the preamble of patent claim 1.

Eine derartige bekannte Befestigungsvorrichtung (DE-PS 25 45 039) besitzt eine Stahlblechklammer, die wegen ihrer Formgebung umständlich herstellbar ist und in besonderen Arbeitsgängen ein Muttergewinde und einen Nietkopf erhält.Such a known fastening device (DE-PS 25 45 039) has a sheet steel clamp, which is difficult to manufacture because of its shape and receives a nut thread and a rivet head in special operations.

Die Erfindung hat die Aufgabe, eine Befestigungsvorrichtung der bezeichneten Art zu schaffen, die sich billiger herstellen läßt. Hierzu sind nach der Erfindung die Merkmale des kennzeichnenden Teiles des Anspruches 1 vorgesehen.The invention has for its object to provide a fastening device of the type described, which can be manufactured cheaper. For this purpose, the features of the characterizing part of claim 1 are provided according to the invention.

Nebenvorteil der erfindungsgemäßen Vorrichtung ist die schmale Bauform, wegen der der Abstand zwischen der Randleiste und einer Vertiefung des zu befestigenden Teiles für die Anbringung der Befestigungsvorrichtung nur klein zu sein braucht. Eine besondere, mit Anspruch 2 gekennzeichnete Maßnahme, den Abstand der Randleiste von dem Rand der Einbauöffnung klein zu halten, führt beispielsweise bei einem Spültischblech zu einem materialsparenden schmalen Wasserfangrand, der auch ästhetisch vorteilhaft ist.In addition to the advantage of the device according to the invention, the narrow design, because of which the distance between the edge strip and a recess of the part to be fastened need only be small for the attachment of the fastening device. A special measure, characterized by claim 2, of keeping the distance of the edge strip from the edge of the installation opening small leads, for example in the case of a sink plate, to a material-saving narrow water catch edge, which is also aesthetically advantageous.

Das Merkmal von Anspruch 3 ist insoweit vorteilhaft, als bei dieser Anordnung der Einrastnase die von dem Spannteil auf die Randleiste ausgeübte Querkraft den festen Sitzeder Einrastnase sichert. Dagegen soll die Kraft, mit der die Klammer von Hand auf die Randleiste aufgesteckt wird, nicht zu groß sein. Dies wird durch das Merkmal von Anspruch 4 erzielt.The feature of claim 3 is advantageous insofar as, in this arrangement of the latching lug, the transverse force exerted by the clamping part on the edge strip ensures the firm seating of the latching lug. In contrast, the force with which the clip is pushed onto the edge strip by hand should not be too great. This is achieved by the feature of claim 4.

Der Anspruch 5 betrifft eine zweckmäßige Ausführungsform im Zusammenhang mit einem U-förmigen Spannteil, dessen Krallen in den Rand der Einbauöffnung eindringen.The claim 5 relates to an expedient embodiment in connection with a U-shaped clamping part, the claws penetrate into the edge of the installation opening.

Die Ansprüche 6, 7 und 8 betreffen eine zweckmäßige Ausführungsform im Zusammenhang mit einem winkelförmigen Spannteil, dessen Krallen in die Rückseite der die Einbauöffnung aufweisenden Platte eindringen. So ermöglicht der Anspruch 6 die*Zusammenfügung der drei Teile der Vorrichtung, nämlich Klammer, Spannteil und Schraube zu einer einzigen Gebrauchseinheit, wobei mit Hilfe eines zweiten Schlitzes entsprechend Anspruch 7 eine lagesichere Führung des Spannteiles an der Klammer gewährleistet ist. Die Kralle nach Anspruch 8 bewirkt die Festrastung des Schraubenhalters, so daß der Monteur keine Hand benötigt, den Schraubenhalter beim Einführen der Schraube in das Blechschraubenloch festzuhalten.
* unverlierbare und bequemeThe claims 6, 7 and 8 relate to an expedient embodiment in connection with an angular clamping part, the claws penetrate into the back of the panel with the installation opening. Thus, claim 6 enables the * assembly of the three parts of the device, namely clamp, clamping part and screw into a single use unit, with the aid of a second slot according to claim 7 ensuring that the clamping part is guided securely on the clamp. The claw according to claim 8 causes the screw holder to be locked in place, so that the fitter does not need a hand to hold the screw holder firmly when inserting the screw into the sheet metal screw hole.
* captive and convenient

In the drawing, the invention is illustrated using exemplary embodiments. The drawing explained below shows with:
  • Figure 1 shows the attachment of a sink plate in the installation opening of a kitchen worktop, with a clamping part acting on the inner edge of the opening.
  • Figure 2 shows an arrangement similar to Figure 1, but with a clamping part acting on the lower surface.
  • 3 shows a further development of the arrangement according to FIG. 2.
  • Figure 4 shows the attachment of Figure 3 in the state of inserting the sink plate before carrying out the bracing.
  • Figure 5 shows the device of Figure 4 in cross section along line VV.

In einer Küchen-Arbeitsplatte 1 ist eine Einbauöffnung 2 ausgeschnitten. Darin sitzt ein Spültischblech 3, Die in einem Abstand vom Rand 4 der Einbauöffnung 2 senkrecht eintauchende Randleiste 5 nimmt über den Umfang eine Anzahl Befestigungsvorrichtungen auf. Diese bestehen aus einer Klammer 6 und einem Spannteil 7, die durch eine Schraube 8 miteinander verbunden sind. Die aus den Einzelteilen 6, 7 und 8 bestehende Vorrichtung als schon im Lieferzustand zusammengesetzter Gebrauchsgegenstand ist auf die Randleiste 5 aufgeclipst worden, bevor das Spültischblech in die Einbauöffnung hineingesetzt wurde.An installation opening 2 is cut out in a kitchen worktop 1. In it sits a sink plate 3, the edge strip 5, which dips vertically at a distance from the edge 4 of the installation opening 2, accommodates a number of fastening devices over the circumference. These consist of a bracket 6 and a clamping part 7, which are connected by a screw 8. The device consisting of the individual parts 6, 7 and 8 as a commodity already assembled in the delivery state has been clipped onto the edge strip 5 before the sink plate has been inserted into the installation opening.

Die Klammer 6 besteht aus spritzbarem Kunststoff wie Polyamid und wird gebildet aus einem dem Rand 4 abgewandten Klammerschenkel 9, der von seiner größten Dicke im Bereich des Klammerrückens 10 spitz zuläuft, und aus dem parallelwandigen anderen Klammerschenkel 11. Der Klammerspalt verläuft um die Einrastnase 12 herum bogenförmig. Ein vom Klammerrücken 10 aus gebohrtes Loch 13 für die Aufnahme der Schraube 8, ,die als sogenannte Blechschraube ausgebildet ist, erstreckt sich in den Klammerschenkel 9 hinein. Der Übergang des Klammerrückens zu dem Schenkel 11 ist eine gerundete Stützfläche 14 für das Spannteil 7. Das Spannteil 7 ist eine U-förmige Stahlfeder mit den Schenkeln 15 und 16, deren Abstand im unverspannten Zustand kleiner ist als die Breite des Klammerrückens 10.The clip 6 consists of injectable plastic such as polyamide and is formed from a clip leg 9 facing away from the edge 4, which tapers from its greatest thickness in the area of the clip back 10, and from the parallel-walled other clip leg 11. The clip gap extends around the latching lug 12 arched. A hole 13 drilled from the back of the clamp 10 for receiving the screw 8, which is designed as a so-called self-tapping screw, extends into the clamp leg 9. The transition from the back of the staple to the leg 11 is a rounded support surface 14 for the tensioning part 7. The tensioning part 7 is a U-shaped steel spring with the legs 15 and 16, the distance between which in the unstressed state is smaller than the width of the back of the staple 10.

Zum Aufclipsen der Klammer 6 auf die Randleiste 5 verformt sich das Blech der Randleiste unter gleichzeitigem federndem Spreizen der Schenkel 9 und 11,elastisch um die Einrastnase 12 herum, die dabei in das entsprechende Loch der Randleiste hineinschnappt. Die Bogenform der Innenseite des Schenkels 9 dient dazu, dem Blech eine glatte Führung zu geben. Ilach dem Aufclipsen wird die Blechschraube 8 angezogen, wodurch der Schenkel 16 des Spannteiles an der Kante von Klammerrücken und -schenkel 9 entlanggleitet. Der andere Schenkel 15 gleitet an der Stützfläche 14 entlang, so daß die an dem Schenkel 15 angeformten Krallen in die Wandung des Randes 4 eindringen. Beide auseinandergespreizten Schenkel 15 und 16 sichern die Randleiste 5 gegen Verschieben, während die Schraube 8 den Geräteeinsatz fest auf eine Dichtung 17 preßt.To clip the clip 6 onto the edge strip 5, the sheet metal of the edge strip deforms while simultaneously resiliently spreading the legs 9 and 11, elastically around the latching lug 12, which snaps into the corresponding hole in the edge strip. The arc shape of the inside of the leg 9 serves to give the sheet a smooth guide. After clipping on, the self-tapping screw 8 is tightened, as a result of which the leg 16 of the clamping part slides along the edge of the clamp back and leg 9. The other leg 15 slides along the support surface 14, so that the claws formed on the leg 15 penetrate into the wall of the edge 4. Both spread legs 15 and 16 secure the edge strip 5 against displacement, while the screw 8 presses the device insert firmly onto a seal 17.

Bei der Anordnung nach Figur 2 sitzt im Anlieferzustand ein winkelförmiger Spannteil 18 auf der Schraube 8, jedoch in einer um 90° verdrehten Stellung auf der Klammer. Erst nach dem Einsetzen des Spültischbleches wird das Spannteil unter Lösen der Schraube 8 in die Gebrauchslage geschwenkt. Der mit Krallen versehene eine Schenkel 19 des Spannteiles greift an der Unterseite der Arbeitsplatte 1 an. Der andere Schenkel 20 entspricht funktionell dem Schenkel 16. Die Figur 2 läßt erkennen, daß bei einer verhältnismäßig engen Einbauöffnung 2 der Abstand zwischen dem Rand 4 und der Klammer 6 nur klein zu sein braucht, wenn das Spannteil 18 an der Unterseite der Arbeitsplatte angreifen kann.In the arrangement according to FIG. 2, an angular clamping part 18 is seated on the screw 8 in the delivery state, but in a position rotated by 90 ° on the clamp. Only after inserting the sink plate is the clamping part pivoted into the position of use by loosening the screw 8. The clawed one leg 19 of the clamping part engages on the underside of the worktop 1. The other leg 20 corresponds functionally to the leg 16. Figure 2 shows that with a relatively narrow installation opening 2, the distance between the edge 4 and the bracket 6 need only be small if the clamping part 18 can attack the underside of the worktop .

Die Anordnung nach Figur 3 ist eine Weiterentwicklung der Anordnung mach Figur 2 insoweit, als sie entbehrlich macrt, für das Schwenken des Spannteiles in die Grebrauchslage zuvor die Schraube 8 zu lösen. Die befindet sich im allgemeinen an schwer zugämgigen Stellen des betreffenden Küchenschrankres. Weiterer Unterschied gegenüber Figur 2 ist die andersartige Ausbildung der Kunststoff klammer.
* Befestigungsvorrichtung The arrangement according to FIG. 3 is a further development of the arrangement according to FIG. 2 insofar as it dispenses with the need to loosen the screw 8 beforehand for pivoting the clamping part into the position of use. It is generally located in difficult-to-access areas of the kitchen cabinet concerned. Another difference compared to Figure 2 is the different design of the plastic bracket.
* Fastening device

Bei der Klammer 21 sitzt die Einrastnase 22 in dem dem Rand 4 der Einbauöffnung 2 abgewandten Schenkel 23. Der andere Schenkel 24 ist gemäß Figur 5 in der Mitte seiner Tiefe ausgespart, so daß aus herstellungstrechnischen Gründen die Einrastnase 22 und zwei die Einrastnase flankierende Schlitze 25 frsiliegen. An dem wegen der Schlitze mittleren Teil 26 des Schenkels sitzt die Einrastnase. Das Schraubenloch 27 erstreckt sich wie bei dier Klammer 6 vom Klammerrücken 28 aus in den Schenkel 23 hinein.
** in Figur 5 nicht sichtbare In the case of the clip 21, the latch 22 is seated in the leg 23 facing away from the edge 4 of the installation opening 2. The other leg 24 is recessed in the middle of its depth, as shown in FIG. 5, so that for reasons of production engineering the latch 22 and two slots 25 flanking the latch frisiliegen. The snap-in lug sits on the part 26 of the leg that is in the middle due to the slots. The screw hole 27 extends, as in the case of the bracket 6, from the bracket back 28 into the leg 23.
** not visible in Figure 5

An der Kante 29, die gebildet wird aus dem Klammerrücken 28 und der- Außenseite des Klammerschenkels 23 ist über eine Wurzel 30 und über einen leicht verbiegbaren Steg 31 ein Schraubenhalter 32 angeformt, der sich in Richtung des Klammerrückens 28 erstreckt und am Ende als Kralle 33 ausgebildet irt, die sich in eine entsprechende Aussparung 3- des Klammerrückens einrasten läßt. Sollte es rus praktischen Gründen vorteilhaft sein, den Schraubenhalter winklig zum Klammerrücken anzufarmen, so besteht dafür kein Hindernis.On the edge 29, which is formed from the back of the staple 28 and the outside of the staple leg 23, a screw holder 32 is formed via a root 30 and an easily bendable web 31, which extends in the direction of the back of the staple 28 and at the end as a claw 33 trained irt, which can be snapped into a corresponding recess 3- of the back of the clip. If for practical reasons it should be advantageous to angle the screw holder to the back of the clamp, there is no obstacle.

Im Anlieferzustand sitzt der Spannteil 35 mit seinem zur Schraube 36 parallelen Schenkel 37 in einem Schlitz 38 und wird durch die in den Schraubenhalter 32 eingesetzte Schraube 36 gehaltert. Schraube und Spannteil liegen in diesem Zustand innerhalb der Kontur des Spültischbleches 3, wenn diese in die Einbauöffnung 2 der Arbeitsplatte 1 hineingesenkt wird. Nach dem Hineinsenken werden vier oder mehr von auf die Randleiste 5 aufgeclipsten Befestigungsvorrichtungen dadurch zum Verspannen vorbereitet, daß der Schraubenhalter 32 um 180° verschwenkt wird. Der mit den Krallen 39 versehene Schenkel des Spannteiles 35 setzt dabei auf die Unterseite der Arbeitsplatte 1 auf, während-der Schenkel 37, an der Außenseite des Klammerschenkels 23 entlanggleitend, weiter in den Schlitz 38 eintaucht. Dieser Schlitz 38 setzt sich flüchtend in einen zweiten Schlitz 40 fort, der unmittelbar an die Außenseite des Klammerschenkels 23 angrenzt und im Ursprungszustand einen Abstand von dem Steg 31 aufweist, der gleich groß ist dem Abstand des erstgenannten Schlitzes 38 von diesem Steg. Die Figur 3 weist aus, daß sich in dem durch die Kralle 33 festgerasteten Schraubenhalter 32 die Schraube 36 leicht festziehen läßt, und daß die von dem Schenkel 37 auf die Klammer 21 ausgeübte Querkraft der Einrastnase 22 einen sicheren Halt in der Randleiste 5 verleiht.In the delivery state, the clamping part 35 is seated his leg 37 parallel to the screw 36 in a slot 38 and is held by the screw 36 inserted into the screw holder 32. In this state, the screw and clamping part lie within the contour of the sink plate 3 when it is lowered into the installation opening 2 of the worktop 1. After sinking in, four or more fastening devices clipped onto the edge strip 5 are prepared for tensioning in that the screw holder 32 is pivoted through 180 °. The leg of the clamping part 35 provided with the claws 39 is placed on the underside of the worktop 1, while the leg 37, sliding along the outside of the clamp leg 23, continues to dip into the slot 38. This slot 38 continues in a flush manner into a second slot 40, which directly adjoins the outside of the clamp leg 23 and in the original state has a distance from the web 31 which is equal to the distance of the first-mentioned slot 38 from this web. 3 shows that the screw 36 can be easily tightened in the screw holder 32 which is locked by the claw 33, and that the transverse force exerted by the leg 37 on the clip 21 gives the latching lug 22 a secure hold in the edge strip 5.
