Abstract

The fixing device has a large-surface head with projecting hollow shaft (2) for a fastening element (3). The inside of the hollow shaft is closed by a swivel cover which in the closed position engages on a projection of the head which is set on a surface running parallel to the cross-sectional surface of the hollow shaft. This surface is formed by a base (13) of an indentation (14) in the head. The base encloses the opening (15) in the head at least in part and the indentation holds the cover in the closed position. The projection is formed as a stud projecting substantially perpendicular from the base and engaging in a through bore (9,10) on the cover.

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-PS 5,118,235 bekannt sind. Diese bekannte Vorrichtung weist 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.Devices such as are known, for example, from US Pat. No. 5,118,235 are used to fasten plate-shaped insulation elements to components. This known device has a large-area head and a hollow shaft protruding from the head. A fastening element, which can be driven into the component by means of a suitable tool, can be inserted into an interior of the hollow shaft via an opening arranged in the large-area head. In the set state, the fastening element is supported on a shoulder of the hollow shaft which is arranged in the interior and points against the setting direction and penetrates the end region of the hollow shaft on the setting direction.

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.Plaster 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 leads to depressions on the surface of the applied layer of plaster. If cleaning material and thus moisture penetrates into the interior of the hollow shaft, this can cause corrosion on the fastening element if it is not made of rustproof material.

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, the opening can be closed by means of a cover. This cover is arranged on the large-area head so as to be pivotable about an articulation axis and, in the closed position, cooperates with a projection which protrudes from the inner wall of the hollow shaft, which runs parallel to the longitudinal axis of the hollow shaft. In the closed position, the cover, with its side pointing counter to the setting direction, lies against the stop edge of the projection facing the interior.

Der Deckel kann 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.When closing the opening or when applying cleaning material, the cover can be pressed or pivoted so far into the interior that the opening is no longer closed and cleaning material can thus get into the interior of the hollow shaft.

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 has for its object to provide a device for attaching insulation elements, in which it is ensured that the force of forces caused by the handling or application of cleaning material, the lid remains securely closed.

Die Lösung dieser Aufgabe erfolgt durch eine Vorrichtung, welche die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist.This object is achieved by a device which has the features stated in the characterizing section of patent claim 1.

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 surface running parallel to the cross-sectional area of the hollow shaft, on which the projection is arranged, serves as a stop surface for the cover so that it cannot be pressed further into the interior of the hollow shaft from the closed position. The arrangement of the projection on the stop surface enables simple and safe interaction with the cover when it is moved into the closed position.

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 cover in the closed position does not protrude beyond the surface of the large-area head facing away from the setting direction, the surface is preferably formed by a bottom at least partially surrounding the opening of a recess arranged in the head and receiving the cover in the closed position.

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 manufacturing reasons, the projection arranged on the bottom is expediently designed as a pin projecting essentially perpendicularly from the bottom, which can be snapped into 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 inseparable connection between the pin and the cover is advantageously achieved by the pin widening stepwise against the setting direction and tapering conically towards its free end, the largest diameter of the pin being larger than the diameter of the through hole. The wall thickness of the cover cooperating with the pin can correspond, for example, at least in the area of the through hole to the distance between the step of the step-like expansion and the bottom of the depression.

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.In order to be able to better insert the tool used to drive in the fastening element into the hollow shaft, the cover is expediently formed in two parts, the cover parts being articulated outside the opening and pivotable about joint axes running parallel to one another. The sides of the cover parts facing each other in the open position serve as a centering aid when inserting 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 sides of the cover parts pointing counter to the setting direction can, for example, be provided with a profile which ensures better adhesion of the cleaning material. Better adhesion also means that tensile forces can act on the cover parts. So that these cover parts remain securely in the closed position even when tensile forces occur, at least two pegs are preferably arranged on the base and each cover part has at least one through hole into which a peg can be 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 the opening is closed, it is immaterial which of the two cover parts is in the closed position first. Both cover parts can therefore also be pivoted into the closed position at the same time.

Die in Fig. 1 dargestellte Vorrichtung dient der Befestigung von nicht dargestellten Isolationselementen an einem ebenfalls nicht dargestellten Bauteil und setzt sich aus einem grossflächigen Kopf 1 und einem sich daran anschliessenden Hohlschaft 2 zusammen. 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 to attach insulation elements, not shown, to a component, also not shown, and is composed of a large-area head 1 and a hollow shaft 2 adjoining it. The hollow shaft 2 has an inner space 4 which is accessible from the outside through an opening 15 arranged in the area of the large-area head 1 and which serves to accommodate a fastening element 3 with which the device can be fixed to the component. An arranged in the interior 4 of the hollow shaft 2, against the Stop face 5 pointing in the direction of setting serves as an abutment for a radially widened region 6 of the fastening element 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 cleaning material, not shown, which is applied to the attached insulation elements, cannot get into the interior 4 of the hollow shaft 2, the opening 15 can be closed by means of two cover parts 7, 8 of a cover, which in the closed position have a depression 13 in the bottom 14 of the head 1 are arranged sunk. Two through bores 9, 10 of each cover part 7, 8 each act together with two pins 11, 12 projecting from the bottom 13.

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 Gelenkachse 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 arranged on the large-area head 1 so as to be pivotable about hinge axes 16, 17 lying outside the opening 15. 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 mutually opposite sides of this recess 14. The length of the cover parts 7, 8 measured parallel to the hinge axis 16, 17 essentially corresponds to a side length of the recess 14. The length of the cover parts measured perpendicular to the hinge axis 16, 17 7, 8 corresponds essentially to half the side length of the recess 14. The wall thickness of the cover parts 7, 8 is essentially matched 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.FIG. 2 shows the enlarged representation of a through bore 9, 10 which interacts with a pin 11, 12. This through hole 9, 10 is of stepped design, the largest diameter of the through hole 9, 10 being arranged in the region of the large-area head 1 pointing counter to the setting direction.

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 gässte Durchmesser D des Zapfens 11, 12 ist grössser ausgebildet als jener Teil der Durchgangsbohrung 9, 10 mit dem kleineren Durchmesser d.The pin 11, 12 projecting essentially vertically from the bottom 13 of the recess 14 has a step-like extension 18, which in turn tapers conically towards the free end of the pin 11, 12. The distance A between the step of the step-like extension 18 and the bottom 13, from which the pin 11, 12 protrudes, corresponds essentially to the wall thickness of the cover parts 7, 8, reduced by the depth T of that area of the through hole 9, 10 with the larger one Diameter. The tapering region of the pin 11, 12 extends over a length L, which essentially corresponds to the depth T of that region of the through hole 9, 10 which has the larger diameter. The closest diameter D of the pin 11, 12 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 the opening 15 is closed, the cover parts 7, 8 are pivoted. The conical tapering of the pins 11, 12 arranged outside the opening 15 come into contact with the mouth areas of the through bores 9, 10 of the cover parts 7, 8. When the cover parts 7, 8 are pivoted further, the radially elastic region having the largest diameter D of the pin 11, 12 is radially compressed. When the cover parts 7, 8 reach the closed position, the compressed area of the pin 11, 12 no longer interacts with the smaller diameter d of the through bores 7, 8 and can therefore expand again. This creates a positive connection between the pins 11, 12 and the cover parts 7, 8.

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