Description

Die Erfindung betrifft eine Profilschiene für Bodenbeläge, insbesondere für Teppiche, mit im Boden zu verankernden stiftartigen Befestigungsteilen, die mit einem verbreiterten Kopf in eine hinterschnittene Längsnut an der Unterseite der Profilschiene eingreifen, wobei die Längsnut eine lichte Höhe aufweist, die der Höhe des Kopfes am Befestigungsteil entspricht und der Querschnitt der Längsnut dem Querschnitt des Kopfes am Befestigungsteil, gesehen in einer Projektion auf die Längsachse des Befestigungsteils, entspricht, wobei ferner der Außenumfang des Stiftes des Befestigungsteils mit einer Mehrzahl von sich radial erstreckenden Vorsprüngen besetzt ist.The invention relates to a profile rail for floor coverings, in particular for carpets, with pin-like fastening parts to be anchored in the floor, which engage with an enlarged head in an undercut longitudinal groove on the underside of the profile rail, the longitudinal groove having a clear height which corresponds to the height of the head Fastening part corresponds and the cross-section of the longitudinal groove corresponds to the cross-section of the head on the fastening part, seen in a projection onto the longitudinal axis of the fastening part, the outer circumference of the pin of the fastening part also being occupied by a plurality of radially extending projections.

Bei einer bekannten profilschiene (DE-GM 86 11 918) ist die Profilschiene ein Hohlprofil, welches an seiner Unterseite einen Längsschlitz aufweist. Die Befestigungsteile besitzen verdickte Köpfe mit abgerundeten Begrenzungsflächen. Zum Verlegen der Profilschiene werden zunächst die Befestigungsteile soweit in den Boden eingeschraubt oder eingesetzt, daß ihre Köpfe mit einem hinreichenden Abstand über die Teppichebene derart vorstehen, daß die Profilschiene mit ihrem Längsschlitz über die Köpfe gedrückt werden kann. Wenn die Höhe der Köpfe der Befestigungsteile nicht den richtigen Abstand zur Teppichebene haben, können entweder die Längskanten des Längsschlitzes nicht unter die Köpfe greifen oder sie haben dort zuviel Spiel. Die Profilschiene muß dann wieder gelöst werden, um die Höhe der Köpfe der Befestigungsteile neu einzustellen.In a known profile rail (DE-GM 86 11 918), the profile rail is a hollow profile which has a longitudinal slot on its underside. The fasteners have thickened heads with rounded boundary surfaces. To lay the profile rail, the fastening parts are first screwed or inserted into the floor to such an extent that their heads protrude a sufficient distance above the carpet level in such a way that the profile rail can be pressed over the heads with its longitudinal slot. If the height of the heads of the fasteners are not at the correct distance from the carpet level, either the longitudinal edges of the longitudinal slot cannot reach under the heads or there is too much play there. The profile rail must then be released again to readjust the height of the heads of the fastening parts.

Es ist ferner eine gattungsgemäße Profilschiene aus der FR-A-1 380 160 bekannt, bei der jedoch der Außenumfang des Stiftes des Befestigungsteils als Schraube ausgebildet ist, oder aber analog dazu eine schraubenförmige Rippe aufweist. Bei der bekannten Ausführung ist der Kopf des Befestigungsteils oberseitig im Querschnitt bogenförmig geformt. Wenn der Stift des Befestigungsteils als Schraube ausgebildet ist, wird das Befestigungsteil in den Boden eingedreht. Im anderen Fall muß das Befestigungsteil in eine entsprechende Bodenöffnung eingeschlagen werden. Bei üblichen, aus Beton oder dergleichen bestehenden Böden in Gebäuden, in die Öffnungen für die Stifte eingebracht werden, sind, unabhängig davon, ob die Stifte eingedreht oder eingeschlagen werden, die damit verbundenen Montagearbeiten aufwendig.A generic profile rail is also known from FR-A-1 380 160, in which, however, the outer circumference of the pin of the fastening part is designed as a screw or, analogously, has a helical rib. In the known embodiment, the head of the fastening part is curved on the upper side in cross section. If the pin of the fastening part is designed as a screw, the fastening part is screwed into the ground. In the other case, the fastening part must be driven into a corresponding floor opening. In the case of conventional floors in buildings made of concrete or the like, into which openings for the pins are introduced, the associated assembly work is complex, regardless of whether the pins are screwed in or hammered in.

Aufgabe der Erfindung ist es, eine Profilschiene der eingangs beschriebenen Gattung so zu verbessern, daß das Verlegen der Profilschiene einfacher ist.The object of the invention is to improve a rail of the type described above so that the laying of the rail is easier.

Diese Aufgabe wird dadurch gelöst, daß die Vorsprünge als ringförmige Lamellen ausgebildet sind, so daß sie sich nach dem Eintreiben des Stiftes in dem zugeordnete Loch des Bodens gegen die Wandung des zugeordneten Loches verspannen.This object is achieved in that the projections are designed as annular lamellae, so that they are braced against the wall of the associated hole after the pin has been driven into the associated hole in the base.

Wird ein Stift, der außenseitig mit einer Mehrzahl von sich radial erstreckenden, ringförmigen Lamellen besetzt ist, in ein Loch eines Bodens eingedrückt, dann verformen sich die Lamellen in axialer Richtung. Deswegen ist für das Eindrücken nur ein geringer Kraftaufwand erforderlich. Wenn die Endlage des Stiftes erreicht ist, verspannen sich die Lamellen gegen die Wandung des zugeordneten Loches und das Befestigungsteil wird in dem zugeordneten Loch des Bodens dort selbsthemmend gehalten. Der Stift kann auch leicht wieder aus dem Loch des Bodens herausgezogen werden, weil die Lamellen sich dabei axial verformen. Eine Beschädigung der Wandung des Loches im Boden kann ausgeschlossen werden.Becomes a pin that has a plurality of radially extending, annular lamellae on the outside is pressed into a hole in a floor, the slats deform in the axial direction. For this reason, only a small amount of force is required for the indentation. When the end position of the pin is reached, the lamellae brace against the wall of the assigned hole and the fastening part is held there self-locking in the assigned hole in the base. The pin can also be easily pulled out of the hole in the base because the slats deform axially. Damage to the wall of the hole in the floor can be excluded.

Bei einer bevorzugten Ausführungsform kann der Kopf des Befestigungsteils, gesehen in Längsachse des Befestigungsteils, einen rechteckigen bis quadratischen Grundriß aufweisen, so daß eine gute Führung des Befestigungsteils in der Nut garantiert ist.In a preferred embodiment, the head of the fastening part, viewed in the longitudinal axis of the fastening part, can have a rectangular to square outline, so that good guidance of the fastening part in the groove is guaranteed.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert.In the following an embodiment of the invention shown in the drawing is explained.

Die einzige Figur zeigt schematisch einen Schnitt durch eine Profilschiene für Bodenbeläge mit einem eingesetzten Befestigungsteil.The single figure shows schematically a section through a profile rail for floor coverings with an inserted fastening part.

Die in der Zeichnung dargestellte Profilschiene 1 kann aus Kunststoff oder Metall, insbesondere Leichtmetall bestehen. Sie besitzt eine gewölbte Oberseite 2 und an ihrer Unterseite zwei sich in Längsrichtung im Bereich der äußeren Längsränder erstreckende äußere Stützleisten 3 sowie innere Stützleisten 4. Die inneren Stützleisten 4 bilden Hinterschneidungen für eine sich in Längsrichtung der Profilschiene 1 erstreckende Längsnut 5, die bei der dargestellten Ausführung einen im wesentlichen rechteckigen Querschnitt besitzt.The profile rail 1 shown in the drawing can consist of plastic or metal, in particular light metal. It has a curved top 2 and on its underside two outer support strips 3 extending in the longitudinal direction in the region of the outer longitudinal edges and inner support strips 4. The inner support strips 4 form undercuts for a longitudinal groove 5 extending in the longitudinal direction of the profile rail 1, which in the illustrated Execution has a substantially rectangular cross section.

In der Längsnut 5 ist der verbreiterte Kopf 6 eines Befestigungsteils 7 in Richtung der Längsnut 5 verschieblich geführt. Der Kopf 6 besitzt, gesehen in Richtung der Längsachse des Befestigungsteils 7 einen rechteckigen bis quadratischen Grundriß. Die Höhe des Kopfes 6 am Befestigungsteil 7 entspricht etwa der lichten Höhe der Längsnut 5. Das ist in der Zeichnung übertrieben dargestellt.In the longitudinal groove 5, the widened head 6 of a fastening part 7 is displaceably guided in the direction of the longitudinal groove 5. The head 6, viewed in the direction of the longitudinal axis of the fastening part 7, has a rectangular to square outline. The height of the head 6 on the fastening part 7 corresponds approximately to the clear height of the longitudinal groove 5. This is exaggerated in the drawing.

An den Kopf 6 des Befestigungsteils 7 schließt ein Stift 8 an, dessen Außenumfang mit einer Mehrzahl von sich radial erstreckenden ringförmigen Lamellen 9 besetzt ist.A pin 8 adjoins the head 6 of the fastening part 7, the outer circumference of which is occupied by a plurality of radially extending annular lamellae 9.

Zum Verlegen der Profilschiene 1 werden in den nicht dargestellten Boden Löcher gebohrt. Eine entsprechende Anzahl von Befestigungsteilen 7 wird mit ihren Köpfen 6 in die Längsnut 5 der profilschiene 1 eingeführt. Dann werden die Stifte 8 der Befestigungsteile 7 in die zugeordneten Löcher eingedrückt. Der Druck erfolgt dabei von der Oberseite 2 der Profilschiene 1 und wird wegen der im wesentlichen spielfreien Führung der Köpfe 6 in der Längsnut 5 auf die Befestigungsteile 7 übertragen. Wenn die Profilschiene 1 genügend tief niedergedrückt ist, verspannen sich die ringförmigen Lamellen 9 gegen die Wandungen der zugeordneten Löcher und die Befestigungsteile 7 werden in den zugeordneten Löchern des Bodens dort selbsthemmend gehalten.For laying the profile rail 1 holes are drilled in the floor, not shown. A corresponding number of fastening parts 7 is inserted with their heads 6 into the longitudinal groove 5 of the profile rail 1. Then the pins 8 of the fastening parts 7 are pressed into the associated holes. The pressure occurs from the top 2 of the profile rail 1 and is transferred to the fastening parts 7 because of the substantially play-free guidance of the heads 6 in the longitudinal groove 5. When the profile rail 1 is depressed sufficiently deep, the annular lamellae 9 brace against the walls of the associated holes and the fastening parts 7 are held there self-locking in the associated holes in the floor.
