Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen von Isolationselementen an einem Bauteil, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for fastening insulation elements to a Component according to the preamble of patent claim 1.

Dem Befestigen von plattenförmigen Isolationselementen an Bauteilen dienen Vorrichtungen, wie sie beispielsweise aus der US-A-5,118,235 oder DE-A- 3 045 986 bekannt sind. Diese bekannten Vorrichtungen weisen einen grossflächigen Kopf und einen vom Kopf abragenden Hohlschaft auf. In einen Innenraum des Hohlschaftes ist über eine im grossflächigen Kopf angeordnete Öffnung ein Befestigungselement einsetzbar, das mittels eines geeigneten Werkzeuges in das Bauteil eintreibbar ist. Im gesetzten Zustand stützt sich das Befestigungselement an einer im Innenraum angeordneten, entgegen der Setzrichtung weisenden Schulter des Hohlschaftes ab und durchsetzt den setzrichtungsseitigen Endbereich des Hohlschaftes.The attachment of plate-shaped insulation elements to components are devices, as are known for example from US-A-5,118,235 or DE-A-3 045 986. These known Devices have a large-scale head and a protruding from the head Hollow shaft on. In an interior of the hollow shaft is over a large area Head arranged opening a fastener can be used, which by means of a suitable Tool is driven into the component. In the set state, this is supported Fastening element arranged on an interior, opposite to the setting direction pointing shoulder of the hollow shaft and passes through the setting direction end region of the hollow shaft.

Auf die Isolationselemente wird Putzmaterial aufgetragen. Dabei ist es wichtig dass kein Putzmaterial in den Innenraum des Hohlschaftes gelangen kann, da dies zu Vertiefungen an der Oberfläche der aufgetragenen Putzschicht führt. Dringt Putzmaterial und damit auch Feuchtigkeit in den Innenraum des Hohlschaftes, so kann dies eine Korrosion an dem Befestigungselement hervorrufen, wenn dieses nicht aus rostfreiem Material besteht.Cleaning material is applied to the insulation elements. It is important that no Cleaning material can get into the interior of the hollow shaft, as this to depressions on the surface of the applied plaster layer leads. Penetrate cleaning material and thus moisture in the interior of the hollow shaft, so this can be a Cause corrosion to the fastener, if this is not made of stainless Material exists.

Damit kein Putzmaterial in den Innenraum des Hohlschaftes gelangen kann, ist die Öffnung mittels eines Deckels verschliessbar. Dieser Deckel ist ausserhalb der Öffnung um eine Gelenkachse schwenkbar an dem grossflächigen Kopf angeordnet und wirkt in der geschlossenen Stellung mit einem Vorsprung zusammen, der von der parallel zur Längsachse des Hohlschaftes verlaufenden Innenwand des Hohlschaftes abragt. In der geschlossenen Stellung liegt der Deckel mit seiner entgegen der Setzrichtung weisenden Seite an der dem Innenraum zugewandten Anschlagkante des Vorsprungs an. So that no cleaning material can get into the interior of the hollow shaft, which is Can be closed by means of a lid. This lid is outside the opening arranged pivotably about a hinge axis on the large-scale head and acts in the closed position with a projection in parallel with the The longitudinal axis of the hollow shaft extending inner wall of the hollow shaft protrudes. In the closed position, the lid is facing with his counter to the setting direction Side on the interior facing the stop edge of the projection.

Bei der Vorrichtung gemäß US-A-5,118,235 kann der Deckel beim Verschliessen der Öffnung oder beim Auftragen von Putzmaterial derart weit in den Innenraum hineingedrückt bzw. verschwenkt werden, dass die Öffnung nicht mehr verschlossen ist und dadurch Putzmaterial in den Innenraum des Hohlschaftes gelangen kann.In the device according to US-A-5,118,235, the lid when closing the opening or when applying cleaning material be pushed so far into the interior or pivoted that the opening is no longer closed and thus cleaning material in the interior of the hollow shaft can get.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Befestigen von Isolationselementen zu schaffen, bei der sichergestellt ist, dass beim Einwirken von Kräften, hervorgerufen durch die Handhabung oder das Auftragen von Putzmaterial, der Deckel sicher geschlossen bleibt.The invention is based on the object, a device for fastening insulation elements which ensures that when forces are exerted, caused by the handling or application of cleaning material, the lid securely closed.

Die Lösung dieser Aufgabe erfolgt durch eine Vorrichtung, welche die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist.The solution to this problem is achieved by a device which in the characterizing Having section of claim 1 features listed.

Die parallel zur Querschnittsfläche des Hohlschaftes verlaufende Fläche, an der der Vorsprung angeordnet ist, dient als Anschlagfläche für den Deckel, damit dieser aus der geschlossenen Stellung nicht weiter in den Innenraum des Hohlschaftes gedrückt werden kann. Die Anordnung des Vorsprunges an der Anschlagfläche ermöglicht ein einfaches und sicheres Zusammenwirken mit dem Deckel, wenn dieser in die geschlossene Stellung bewegt wird.The parallel to the cross-sectional area of the hollow shaft extending surface on which the projection is arranged, serves as a stop surface for the lid, so that this from the closed Position can not be pushed further into the interior of the hollow shaft can. The arrangement of the projection on the stop surface allows a simple and safe cooperation with the lid, when this in the closed Position is moved.

Damit der Deckel in der geschlossenen Stellung die der Setzrichtung abgewandte Oberfläche des grossflächigen Kopfes nicht überragt, ist vorzugsweise die Fläche von einem die Öffnung wenigstens teilweise umgebenden Boden einer im Kopf angeordneten, den Deckel in der geschlossenen Stellung aufnehmenden Vertiefung gebildet.So that the lid in the closed position facing away from the setting surface of the large-scale head is not surmounted, is preferably the area of one the opening at least partially surrounding bottom of a arranged in the head, the Cover formed in the closed position receiving recess.

Aus herstelltechnischen Gründen ist zweckmässigerweise der an dem Boden angeordnete Vorsprung als im wesentlichen senkrecht von dem Boden abragender Zapfen ausgebildet, der in einer am Deckel angeordneten Durchgangsbohrung einrastbar ist.For reasons of manufacturing technology is conveniently arranged on the ground Projection than substantially perpendicular projecting from the bottom pin formed, which can be latched in a through hole arranged on the cover.

Eine unlösbare Verbindung zwischen dem Zapfen und dem Deckel wird vorteilhafterweise erreicht, indem sich der Zapfen entgegen der Setzrichtung stufenförmig erweitert und zu seinem freien Ende hin konisch verjüngt, wobei der grösste Durchmesser des Zapfens grösser ist als der Durchmesser der Durchgangsbohrung. Die Wandstärke des mit dem Zapfen zusammenwirkenden Deckels kann beispielsweise wenigstens im Bereich der Durchgangsbohrung dem Abstand zwischen der Stufe der stufenförmigen Erweiterung und dem Boden der Vertiefung entsprechen. An insoluble connection between the pin and the lid is advantageously achieved by the pin expands stepwise against the setting direction and conically tapered towards its free end, with the largest diameter of the Spigot is greater than the diameter of the through hole. The wall thickness of the For example, at least in the area cooperating with the pin cover the through hole the distance between the step of the stepped extension and correspond to the bottom of the well.

Um das dem Eintreiben des Befestigungselementes dienende Werkzeug besser in den Hohlschaft einführen zu können, ist zweckmässigerweise der Deckel zweiteilig ausgebildet, wobei die Deckelteile ausserhalb der Öffnung angelenkt und um parallel zueinander verlaufende Gelenkachsen schwenkbar sind. Die einander in der geöffneten Stellung zugewandten Seiten der Deckelteile dienen dabei als Zentrierhilfe beim Einsetzen des Werkzeugs.To the serving the driving of the fastener tool better in the To be able to introduce hollow shaft, the cover is expediently designed in two parts, wherein the lid parts hinged outside the opening and around each other in parallel extending hinge axes are pivotable. The each other in the open Position facing sides of the lid parts serve as a centering when inserting of the tool.

Die entgegen der Setzrichtung weisenden Seiten der Deckelteile können beispielsweise mit einer Profilierung versehen sein, die eine besser Haftung des Putzmaterials gewährleistet. Eine bessere Haftung bedeutet auch, dass Zugkräfte auf die Deckelteile einwirken können. Damit diese Deckelteile auch beim Auftreten von Zugkräften sicher in der geschlossenen Stellung verbleiben, sind vorzugsweise an dem Boden wenigstens zwei Zapfen angeordnet und jedes Deckelteil weist wenigtens eine Durchgangsbohrung auf, in die ein Zapfen einrastbar ist.The opposite to the setting direction facing sides of the cover parts, for example be provided with a profiling that ensures better adhesion of the cleaning material. Better adhesion also means that tensile forces act on the lid parts can. Thus, these cover parts safely in the occurrence of tensile forces in the remain closed position, preferably at the bottom at least two Pins arranged and each cover part has a small throughput hole, in which a pin is latched.

Beim Verschliessen der Öffnung ist es unwesentlich, welcher der beiden Deckelteile zuerst die geschlossene Stellung einnimmt. Es können daher auch beide Deckelteile gleichzeitig in die geschlossene Stellung verschwenkt werden.When closing the opening, it is immaterial which of the two cover parts first occupy the closed position. It can therefore also both lid parts be pivoted simultaneously in the closed position.

Der Hohlschaft 2 weist einen Innenraum 4 auf, der durch eine im Bereich des grossflächigen Kopfes 1 angeordnete Öffnung 15 von aussen zugänglich ist und der der Aufnahme eines Befestigungselementes 3 dient, mit dem die Vorrichtung an dem Bauteil festlegbar ist. Eine im Innenraum 4 des Hohlschaftes 2 angeordnete, entgegen der Setzrichtung weisende Anschlagfläche 5 dient als Widerlager für einen radial erweiterten Bereich 6 des Befestigungselementes 3.The device shown in Fig. 1 is used for attachment of not shown Isolation elements on a likewise not shown component and is made up a large-scale head 1 and an adjoining hollow shaft 2 together. The hollow shaft 2 has an inner space 4, which by a in the region of large-scale head 1 arranged opening 15 is accessible from the outside and the Receiving a fastener 3 is used, with which the device on the component is determinable. One arranged in the interior 4 of the hollow shaft 2, opposite to the Setting direction facing stop surface 5 serves as an abutment for a radially expanded Area 6 of the fastener. 3

Damit nicht dargestelltes Putzmaterial, das auf die befestigten Isolationselemente aufgetragen wird, nicht in den Innenraum 4 des Hohlschaftes 2 gelangen kann, ist die Öffnung 15 mittels zweier Deckelteile 7, 8 eines Deckels verschliessbar, die in der geschlossenen Stellung in einer einen Boden 13 aufweisenden Vertiefung 14 des Kopfes 1 versenkt angeordnet sind. Dabei wirken jeweils zwei Durchgangsbohrungen 9, 10 jedes Deckelteils 7, 8 mit jeweils zwei vom Boden 13 abragen Zapfen 11, 12 zusammen.So that not shown plaster material applied to the attached insulation elements is, can not get into the interior 4 of the hollow shaft 2, is the opening 15 by means of two cover parts 7, 8 of a lid closable, in the closed Position sunk in a bottom 13 having recess 14 of the head 1 are arranged. In each case two through holes 9, 10 each act Cover part 7, 8 with two each protrude from the bottom 13 pins 11, 12 together.

Beide Deckelteile 7, 8 sind um ausserhalb der Öffnung 15 liegende Gelenkachsen 16, 17 schwenkbar an dem grossflächigen Kopf 1 angeordnet. Die Projektionsfläche der Vertiefung 14 erstreckt sich um die Öffnung 15 und hat eine im wesentlichen quadratische Form. Die Gelenkachsen 16, 17 erstrecken sich entlang zweier einander gegenüberliegender Seiten dieser Vertiefung 14. Die parallel zur Gelenkachse 16, 17 gemessene Länge der Deckelteile 7, 8 entspricht im wesentlichen einer Seitenlänge der Vertiefung 14. Die senkrecht zur Geienkachse 16, 17 gemessen Länge der Deckelteile 7, 8 entspricht im wesentlichen der halben Seitenlänge der Vertiefung 14. Die Wandstärke der Deckelteile 7, 8 ist im wesentlichen auf die Tiefe der Vertiefung 14 abgestimmt.Both cover parts 7, 8 are located about the opening 15 lying hinge axes 16, 17th pivotally mounted on the large-scale head 1. The projection surface of the depression 14 extends around the opening 15 and has a substantially square Shape. The hinge axes 16, 17 extend along two opposite ones Side of this recess 14. The measured parallel to the hinge axis 16, 17 Length of the lid parts 7, 8 corresponds substantially to a side length of the recess 14. The perpendicular to Geienkachse 16, 17 measured length of the cover parts 7, 8 corresponds essentially half the side length of the recess 14. The wall thickness of the Cover parts 7, 8 is tuned substantially to the depth of the recess 14.

In der Fig. 2 ist die vergrösserte Darstellung einer mit einem Zapfen 11, 12 zusammenwirkenden Durchgangsbohrung 9, 10 dargestellt. Diese Durchgangsbohrung 9, 10 ist stufenförmig ausgebildet, wobei der grösste Durchmesser der Durchgangsbohrung 9, 10 in dem entgegen der Setzrichtung weisenden Bereich des grossflächigen Kopfes 1 angeordnet ist.In Fig. 2 is an enlarged view of one with a pin 11, 12 cooperating Through hole 9, 10 shown. This through hole 9, 10 is formed step-shaped, wherein the largest diameter of the through hole 9, 10th in the opposite to the setting direction facing area of the large-scale head. 1 is arranged.

Der von dem Boden 13 der Vertiefung 14 im wesentlichen senkrecht abragende Zapfen 11, 12 weist eine stufenförmige Erweiterung 18 auf, die sich zum freien Ende des Zapfens 11, 12 hin wiederum konisch verjüngt. Der Abstand A zwischen der Stufe der stufenförmigen Erweiterung 18 und dem Boden 13, von dem der Zapfen 11,12 abragt, entspricht im wesentlichen der Wandstärke der Deckelteile 7, 8, reduziert um die Tiefe T jenes Bereiches der Durchgangsbohrung 9, 10 mit dem grösseren Durchmesser. Der sich verjüngende Bereich des Zapfens 11, 12 erstreckt sich über eine Länge L, die im wesentlichen der Tiefe T jenes Bereiches der Durchgangsbohrung 9, 10 entspricht, die den grösseren Durchmesser aufweist. Der gösste Durchmesser D des Zapfens 11, 12 ist grössser ausgebildet als jener Teil der Durchgangsbohrung 9, 10 mit dem kleineren Durchmesser d.Of the bottom 13 of the recess 14 substantially perpendicular projecting pin 11, 12 has a stepped extension 18, which extends to the free end of Taper 11, 12 out again tapered conically. The distance A between the stage of stepped extension 18 and the bottom 13 from which the pin 11,12 protrudes, essentially corresponds to the wall thickness of the cover parts 7, 8, reduced by the depth T that region of the throughbore 9, 10 with the larger diameter. Of the Tapered portion of the pin 11, 12 extends over a length L, in the substantially corresponds to the depth T of that region of the through hole 9, 10, the has the larger diameter. The largest diameter D of the pin 11, 12th is larger than that part of the through hole 9, 10 with the smaller Diameter d.

Beim Verschliessen der Öffnung 15 werden die Deckelteile 7, 8 verschwenkt. Dabei gelangen die konischen Verjüngungen der ausserhalb der Öffnung 15 angeordneten Zapfen 11, 12 mit den Mündungsbereichen der Durchgangsbohrungen 9, 10 der Deckelteile 7, 8 in Berührung. Beim weiteren Verschwenken der Deckelteile 7, 8 wird der radial elastische, den grössten Durchmesser D des Zapfens 11,12 aufweisende Bereich radial zusammengedrückt. Wenn die Deckelteile 7, 8 die geschlossene Stellung erreichen, wirkt der zusammengedrückte Bereich des Zapfens 11, 12 nicht mehr mit dem kleineren Durchmesser d der Durchgangsbohrungen 7, 8 zusammen und kann sich daher wieder ausdehnen. Somit entsteht eine formschlüssige Verbindung zwischen den Zapfen 11, 12 und den Deckelteilen 7, 8.When closing the opening 15, the cover parts 7, 8 are pivoted. Get there the conical tapers arranged outside the opening 15 Spigots 11, 12 with the mouth areas of the through holes 9, 10 of the lid parts 7, 8 in contact. Upon further pivoting of the cover parts 7, 8 of the radial elastic, the largest diameter D of the pin 11,12 having area radially pressed together. When the lid parts 7, 8 reach the closed position, the compressed area of the pin 11, 12 no longer interacts with the smaller one Diameter d of the through holes 7, 8 together and can therefore again expand. This creates a positive connection between the pins 11, 12th and the lid parts 7, 8.

Die Wandstärke des grossflächigen Kopfes 1 nimmt zu dessen Aussenkontur hin ab.The wall thickness of the large-scale head 1 decreases towards its outer contour.
