Abstract

The inner space (4) of the hollow shaft (2) is freely accessible via an opening (15). The opening in the head (1) is closable by a closure cap. This cap is formed by two covers (7,8) on both sides of the head (1) and joined outside the opening. The covers are pivotable around link axes (16,17) running parallel to one another and are securable to one another in the closed state with the aid of inter-engaging locking components arranged in planes of the covers running parallel to the longitudinal axis of the hollow shaft. The first lock is formed by at least one projection arranged in an extended area (18) of the first cover (7) and the second lock is formed by at least one recess in the area of a cut-out (19) of the second cover (8).

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 Verschlusselementes verschliessbar. Dieses Verschlusselement ist ausserhalb der Öffnung schwenkbar an dem grossflächigen Kopf angeordnet und hintergreift in der geschlossenen Stellung einen Vorsprung, der von der parallel zur Längsachse des Hohlschaftes verlaufenden Innenwand des Hohlschaftes abragt. In der geschlossenen Stellung liegt das Verschlusselement mit seiner entgegen der Setzrichtung weisenden Seite an der dem Innenraum zugewandten Anschlagkante des Vorsprungs an. In der geschlossenen Stellung ragt das Verschlusselement im wesentlichen parallel zur Längsachse des Hohlschaftes von der dem Hohlschaft abgewandten Seite des grossflächigen Kopfes ab.So that no cleaning material can get into the interior of the hollow shaft, the opening can be closed by means of a closure element. This closure element is pivotally arranged outside the opening on the large-area head and, in the closed position, engages behind a projection which projects from the inner wall of the hollow shaft, which runs parallel to the longitudinal axis of the hollow shaft. In the closed position, the closure element, with its side pointing counter to the setting direction, bears against the stop edge of the projection facing the interior. In the closed position, the closure element projects essentially parallel to the longitudinal axis of the hollow shaft from the side of the large-area head facing away from the hollow shaft.

Beim Befestigen von Isolationselementen an einem Bauteil werden Vorrichtungen verwendet, bei denen die Länge des Hohlschaftes auf die Dicke der Isolationselemente angepasst ist. Da sich das Widerlager für das Befestigungselement im setzrichtungsseitigen Bereich des Innenraumes des Hohlschaftes befindet, muss der in den Hohlschaft ragende Teil des Werkzeugs, der dem Eintreiben des Befestigungselementes dient, eine grosse Länge aufweisen.When attaching insulation elements to a component, devices are used in which the length of the hollow shaft is adapted to the thickness of the insulation elements. Since the abutment for the fastening element is located in the region of the interior of the hollow shaft on the setting direction, the part of the tool which projects into the hollow shaft and which serves to drive in the fastening element must have a great length.

Aufgrund des von dem Kopf abragenden Verschlusselementes muss das Werkzeug allerdings eine noch grössere Länge aufweisen, damit eine Beschädigung des Verschlusselementes, beispielsweise durch einen Handgriff oder ein Gehäuseteil des Werkzeugs, beim Eintreiben des Befestigungselementes nicht erfolgt. Durch den weit vom Kopf abragenden Verschlussdeckel können nur Spezialwerkzeuge mit besonders grosser Länge verwendet werden. Derartige Spezialwerkzeuge sind aufwendig in der Herstellung und teuer in der Anschaffung, insbesondere wenn es sich um pulverkraftbetriebene Setzgeräte handelt, die für die hier vorliegenden Anwendungsfälle häufig verwendet werden.However, due to the locking element protruding from the head, the tool must have an even greater length so that the locking element is not damaged, for example by a handle or a housing part of the tool, when the fastening element is being driven in. Due to the locking cap, which protrudes far from the head, only special tools with a particularly long length can be used. Such special tools are complex to manufacture and expensive to purchase, especially when it comes to powder-operated setting tools that are frequently used for the present applications.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Befestigen von Isolationselementen zu schaffen, bei der sich das dem Verschliessen der Öffnung dienende Verschlusselement nicht störend auf das dem Eintreiben des Befestigungselementes in das Bauteil dienende Werkzeug auswirkt. Zudem soll das Verschlusselement ohne besondere Vorkehrungen in die geschlossene Stellung verschwenkt werden können.The invention has for its object to provide a device for fastening insulation elements, in which the closure element serving to close the opening does not interfere with the tool used to drive the fastening element into the component. In addition, the closure element should be able to be pivoted into the closed position without any special precautions.

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.

Das erfindungsgemäss ausgestaltete Verschlusselement wird aus zwei am Kopf beidseits und ausserhalb der Öffnung angelenkten Deckeln gebildet, die um parallel zueinander verlaufende Gelenkachsen schwenkbar und in der geschlossenen Stellung mit Hilfe von Verriegelungsmitteln miteinander verrastbar sind, die an parallel zur Längsachse des Hohlschaftes verlaufenden Ebenen der Deckel angeordnet sind. Die dem Verschliessen der Öffnung dienenden Deckel sind während des Eintreibvorganges des Befestigungselementes in das Bauteil parallel zur Längserstreckung des Hohlschaftes ausgerichtet und ragen entgegen der Setzrichtung vom Kopf ab. Dadurch dass die senkrecht zur Gelenkachse erstreckende Länge der Deckel sehr klein ist, können herkömmliche Werkzeug für das Eintreiben des Befestigungselementes verwendet werden. Die an beiden Deckeln angeordneten Verriegelungsmittel greifen im geschlossenen Zustand der Deckel formschlüssig ineinander.The closure element designed according to the invention is formed from two lids hinged to the head on both sides and outside of the opening, which can be pivoted about joint axes running parallel to one another and can be locked together in the closed position with the aid of locking means which are arranged on planes of the lids running parallel to the longitudinal axis of the hollow shaft are. The lids serving to close the opening are parallel to the longitudinal extension of the hollow shaft during the driving process of the fastening element into the component aligned and protrude from the head against the setting direction. Because the length of the cover, which extends perpendicular to the hinge axis, is very small, conventional tools can be used for driving in the fastening element. The locking means arranged on both lids interlock positively when the lids are closed.

Um eine gute gegenseitige Verriegelung der beiden Deckel und eine gute formschlüssige Verrieglung erreichen zu können sind vorzugsweise ein erstes Verriegelungsmittel von wenigstens einem an einem verlängerten Bereich des ersten Deckels angeordneten Vorsprung und ein zweites Verriegelungsmittel von wenigstens einer im Bereich eines Ausschnitts des zweiten Deckels angeordneten Ausnehmung gebildet. In der geschlossenen Stellung der beiden Deckel ragt der Vorsprung des ersten Deckels in den entsprechend ausgebildeten Ausschnitt des zweiten Deckels, so dass die Verriegelungsmittel beider Deckel formschlüssig miteinander zusammenwirken können.In order to be able to achieve a good mutual locking of the two lids and a good positive locking, a first locking means is preferably formed by at least one projection arranged on an extended area of the first lid and a second locking means by at least one recess arranged in the area of a cutout of the second lid . In the closed position of the two lids, the projection of the first lid protrudes into the correspondingly designed cutout of the second lid, so that the locking means of the two lids can interact with one another in a form-fitting manner.

Aus Gründen der einfachen Herstellung ist zweckmässigerweise der Vorsprung von einer - von einer ersten Ebene des verlängerten Bereiches abragenden - Rippe und die Ausnehmung von einer - in einer zweiten Ebene des Ausschnittes angeordneten - Nut gebildet.For reasons of simple manufacture, the projection is expediently formed by a rib, which projects from a first plane of the extended region, and the recess is formed by a groove, which is arranged in a second plane of the cutout.

Die entgegen der Setzrichtung weisenden Seiten der Deckel können beispielsweise mit einer Profilierung versehen sein, die eine bessere Haftung des Putzmaterials gewährleistet. Eine bessere Haftung bedeutet auch, dass Zugkräfte auf die Deckel einwirken können. Damit diese Deckel auch beim Auftreten von Zugkräften sicher in der geschlossenen Stellung verbleiben, sind vorzugsweise an dem verlängerten Bereich zwei einander diametral gegenüberliegende, parallel zueinander verlaufende erste Ebenen angeordnet, von denen Rippen abragen, die mit zwei Nuten zusammenwirken, die im Bereich des Ausschnittes an zwei einander diametral gegenüberliegenden, parallel zueinander verlaufenden zweiten Ebenen angeordnet sind.The sides of the cover pointing in the opposite direction to the setting can be provided, for example, with a profile which ensures better adhesion of the cleaning material. Better adhesion also means that tensile forces can act on the cover. To ensure that these lids remain securely in the closed position even when tensile forces occur, two diametrically opposed, parallel first planes are preferably arranged on the extended area, from which ribs project, which interact with two grooves that engage in the area of the cutout two diametrically opposed, parallel, mutually parallel planes are arranged.

Beim Verschliessen der Öffnung ist es unwesentlich, welcher der beiden Deckel zuerst die geschlossene Stellung einnimmt. Es können daher auch beide Deckel gleichzeitig in die geschlossene Stellung verschwenkt werden.When the opening is closed, it is immaterial which of the two lids first assumes the closed position. Both lids can therefore also be pivoted into the closed position at the same time.

Die Erfindung wird anhand einer Zeichnung, die ein Ausführungsbeispiel wiedergibt, näher erläutert.The invention will be explained in more detail with reference to a drawing which shows an embodiment.

Die 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 is used to fasten 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 interior 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. A stop surface 5, which is arranged in the interior 4 of the hollow shaft 2 and points against the setting direction, 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 Deckel 7, 8 verschliessbar, die in der geschlossenen Stellung in einer Vertiefung 14 versenkt angeordnet sind. Dadurch wird verhindert, dass die geschlossenen Deckel 7, 8 die von der Setzrichtung abgewandte Oberfläche des grossflächigen Kopfes 1 überragen.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 lids 7, 8, which are sunk in a recess 14 in the closed position. This prevents the closed lids 7, 8 from projecting beyond the surface of the large-area head 1 facing away from the setting direction.

Beide Deckel 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 Deckel 7, 8 entspricht im wesentlichen einer Seitenlänge der Vertiefung 14. Die senkrecht zur Gelenkachse 16, 17 gemessene Länge der Deckel 7, 8 entspricht im wesentlichen der halben Seitenlänge der Vertiefung 14 mit dem Boden 13. Die Stärke der Deckel 7, 8 ist im wesentlichen auf die Tiefe der Vertiefung 14 abgestimmt.Both covers 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 depression 14. The length of the covers 7, 8 measured parallel to the hinge axis 16, 17 essentially corresponds to a side length of the depression 14. The length of the covers measured perpendicular to the hinge axis 16, 17 7, 8 corresponds essentially to half the side length of the recess 14 with the bottom 13. The thickness of the cover 7, 8 is essentially matched to the depth of the recess 14.

Beim Verschwenken der beiden Deckel 7, 8 in die geschlossene Stellung greift ein verlängerter Bereich 18 eines ersten Deckels 7 in einen entsprechend ausgebildeten Ausschnitt 19 eines zweiten Deckels 8. An parallel zur Längserstreckung des Hohlschaftes 2 verlaufenden Ebenen E1, E2 der geschlossenen Deckel 7, 8 sind Vorsprünge in Form von Rippen 9, 10 und Ausnehmungen in Form von Nuten 11, 12 angeordnet. Sowohl die Rippen 9, 10 als auch die Nuten 11, 12 erstrecken sich senkrecht zur Längserstreckung des Hohlschaftes 2, verlaufen parallel zueinander und sind einander diametral gegenüberliegend angeordnet.When the two lids 7, 8 are pivoted into the closed position, an extended region 18 of a first lid 7 engages in a correspondingly designed cutout 19 of a second lid 8. At levels E1, E2 of the closed lids 7, 8 which run parallel to the longitudinal extension of the hollow shaft 2 projections in the form of ribs 9, 10 and recesses in the form of grooves 11, 12 are arranged. Both the ribs 9, 10 and the grooves 11, 12 extend perpendicular to the longitudinal extension of the hollow shaft 2, run parallel to one another and are arranged diametrically opposite one another.

Die Rippen 9, 10 und die Nuten 11, 12 weisen dreieckige Querschnittsflächen auf. Die Wandstärke des grossflächigen Kopfes 1 nimmt zu dessen Aussenkontur hin ab.The ribs 9, 10 and the grooves 11, 12 have triangular cross-sectional areas. The wall thickness of the large-area head 1 decreases towards its outer contour.
