Abstract

A fastening device for fittings on wings and/or frames of windows, doors or the like, formed from metal and/or plastic sections, is described. The fastening device is especially suitable for the bearing rose 5 of the actuating mechanism of driving-rod fittings. It consists of screw members 8 with a threaded shank 8a and a thickened head part 8b which is equipped with tool engagement surfaces 13. When the windows, doors or the like are in the closed position, at least the head parts 8b of the screw members 8 are arranged within the free space between the rebate surfaces of the wing 1 and frame 2 and the end faces 8c of the head parts 8b confront the outside of the window or door. So that, when the wing 1 is locked in the closed position on the fixed frame 2, the screw members cannot be released even when their respective installation region is exposed by the execution of outer bores in the metal and/or plastic sections or by the bending of section parts, the end faces 8c of the head parts 8b on the screw members 8 have a conical or spherical shape. The tool engagement surfaces 13 are located under the end faces 8c on the head parts 8b and are accessible only from the side. At least the head parts 8b of the screw members 8 are hardened or are provided on their end faces 8c with an armour plating. <IMAGE>

Description

Die Erfindung betrifft eine Befestigungsvorrichtung für Beschlagteile an den aus Metall- und/oder Kunststoffprofilen gebildeten Flügeln und/oder Rahmen von Fenstern, Türen od. dgl., insbesondere von Betätigungsgetrieben für Treibstangenbeschläge, bestehend aus Schraubgliedern mit einem Gewindeschaft und einem verdickten Kopfteil, der mit Werkzeug-Angriffsflächen versehen ist, wobei zumindest die Kopfteile der Schraubglieder bei in Schließlage befindlichen Fenstern, Türen od. dgl. innerhalb des Freiraums zwischen den Falzflächen von Flügel und Rahmen liegen und die Endflächen der Kopfteile der Außenseite des Fensters bzw. der Tür od. dgl. zugewendet sind.The invention relates to a fastening device for fitting parts on the sashes and / or frames formed from metal and / or plastic profiles of windows, doors or the like, in particular of actuating gears for espagnolette fittings, consisting of screw members with a threaded shaft and a thickened head part with Tool-engaging surfaces are provided, with at least the head parts of the screw members in the closed position of windows, doors or the like lying within the free space between the rebated surfaces of the sash and frame and the end surfaces of the head parts of the outside of the window or door or the like are turned.

Befestigungsvorrichtungen dieser Art sind bereits bekannt, wie beispielsweise dem DE-GM 69 35 673 entnommen werden kann. In diesem Falle wird die Lagerrosette eines Bedienungshandgriffes am Flügelprofil von der Unterseite des Überschlag-Profilteils aus mittels zweier Schraubglieder befestigt, derart, daß diese von außen unsichtbar sind, wenn der Flügel in der Schließstellung am feststehenden Rahmen anliegt. Ferner werden die Schraubglieder nach diesem Stand der Technik zusätzlich benutzt, um eine Bedienungssperre mit dem Flügel zu verbinden, wobei diese Bedienungssperre an der Falzfläche des Flügels liegt und in dessen Schließlage am feststehenden Rahmen ebenfalls eine verdeckte Einbaulage einnimmt.Fastening devices of this type are already known, such as can be found in DE-GM 69 35 673. In this case, the rosette of an operating handle is attached to the wing profile from the underside of the rollover profile part by means of two screw members, such that they are invisible from the outside when the wing rests on the fixed frame in the closed position. Furthermore, the screw members according to this prior art are additionally used to connect an operating lock to the wing, this operating lock lies on the rebate surface of the sash and in its closed position also occupies a concealed installation position on the fixed frame.

Zur Erhöhung der Einbruchsicherheit kann zwischen dem Bedienungshandgriff und dessen Lagerrosette noch ein Schloß vorgesehen werden, das zumindest bei in Schließlage am Rahmen verriegeltem Flügel einrückbar ist und dann den Treibstangenbeschlag gegen Betätigung sperrt.To increase the security against burglary, a lock can be provided between the operating handle and its bearing rosette, which can be engaged at least when the sash is locked in the closed position and then locks the connecting rod fitting against actuation.

Eine Unzulänglichkeit bei dieser bekannten Befestigungsvorrichtung liegt darin, daß die am verdickten Kopfteil der Schraubglieder ausgebildeten Werkzeug-Angriffsflächen im Freiraum zwischen den Falzflächen von Flügel und Rahmen eine solche Lage einnehmen, daß sie von der Außenseite des Fensters oder der Tür her, beispielsweise durch Anbringen von Bohrungen oder auch durch Abbiegen von Profilteilen, so zugänglich gemacht werden können, daß die Schraubglieder sich unter Zuhilfenahme geeigneter Werkzeuge - Schraubendreher, Steckschlüssel od. dgl. - lösen lassen.An inadequacy in this known fastening device is that the tool-engaging surfaces formed on the thickened head part of the screw members assume such a position in the free space between the folded surfaces of the sash and frame that they come from the outside of the window or the door, for example by attaching Bores or by bending profile parts can be made accessible so that the screw members can be loosened with the help of suitable tools - screwdriver, socket wrench or the like.

Es ist dann möglich, den Bedienungsgriff mit seiner Lagerrosette und dem Betätigungsgetriebe unwirksam zu machen sowie den Treibstangenbeschlag durch Kraftangriff von außen her zu betätigen. Damit lassen sich die vorhandenen Riegelstellen zwischen dem Flügel und dem feststehenden Rahmen ausrücken und der Flügel kann in Öffnungsstellung gebracht werden.It is then possible to make the control handle with its bearing escutcheon and the actuating gear ineffective and to actuate the connecting rod fitting by force application from the outside. This means that the existing locking points between the sash and the fixed frame can be disengaged and the sash can be brought into the open position.

Die Einbruchsicherheit solcher Fenster und Türen od. dgl. ist damit beeinträchtigt.The security against burglary of such windows and doors or the like is thus impaired.

Aufgabe der Erfindung ist es mit geringem technischem Aufwand ein Befestigungsvorrichtung der gattungsgemäßen Art zu schaffen, an der die Schraubglieder bei in Schließlage am feststehenden Rahmen verriegeltem Flügel auch dann nicht gelöst werden können, wenn ihr jeweiliger Einbaubereich durch Anbringen außenseitiger Bohrungen an den Metall- und/oder Kunststoffprofilen oder aber durch Abbiegen von Profilteilen freigelegt wird.The object of the invention is to create a fastening device of the generic type with little technical effort, on which the screw members cannot be loosened when the sash is locked in the closed position on the fixed frame even if their respective installation area is provided by drilling outside holes on the metal and / or plastic profiles or is exposed by bending profile parts.

Die Lösung dieser Aufgabe wird nach dem Kennzeichen des Anspruchs 1 erfindungsgemäß dadurch erreicht, daß die Endflächen der Kopfteile an den Schraubgliedern eine konische oder sphärische Gestalt aufweisen, daß die Werkzeug-Angriffsflächen unterhalb dieser Endflächen an den Kopfteilen liegen und nur von der Seite her zugänglich sind, und daß dabei zumindest die Kopfteile der Schraubglieder gehärtet oder an ihren Endfläche mit einer Panzerbeschichtung versehen sind.This object is achieved according to the invention by the fact that the end faces of the head parts on the screw members have a conical or spherical shape, that the tool engagement surfaces are below these end faces on the head parts and are only accessible from the side , and that at least the head parts of the screw members are hardened or are provided with an armor coating on their end face.

Durch diese erfindungsgemäßen Maßnahmen wird einerseits erreicht, daß die Kopfteile der Schraubglieder von außen her nicht angebohrt oder abgeschliffen werden können, weil ein Bohrer oder Schleifkopf beim Auftreffen auf deren gehärtete Endflächen seitwärts abgleitet bzw. ausglenkt wird. Andererseits haben dabei die Werkzeug-Angriffsflächen der Schraubglieder eine solche Lage, daß Betätigungswerkzeuge mit ihnen nur bei geöffnetem Flügel in Eingriff bringbar sind, so daß die Schraubglieder nur in diesem Falle gelöst bzw. angezogen werden können.By means of these measures according to the invention, on the one hand it is achieved that the head parts of the screw members cannot be drilled or ground from the outside, because a drill or grinding head slides or deflects sideways when striking their hardened end faces. On the other hand, the tool engagement surfaces of the screw members have such a position that actuating tools can only be brought into engagement with them when the sash is open, so that the screw members can only be loosened or tightened in this case.

Nach Anspruch 2 können erfingungsgemäß die Werkzeug-Angriffsflächen von einer Kreuzloch-Anordnung gebildet werden, die mit einem stiftförmigen Betätigungswerkzeug nur von der Seite her zugänglich ist und daher durch eine größere Anzahl begrenzter Winkeldrehungen das Anziehen oder auch Lösen der Schraubglieder bei geöffnetem Fenster bzw. geöffneter Tür ermöglicht.According to claim 2, according to the invention, the tool engagement surfaces can be formed by a cross-hole arrangement which is only accessible from the side with a pin-shaped actuating tool and therefore can be tightened or loosened by a larger number of limited angular rotations when the window is open or open Door allows.

Nach Anspruch 3 können aber auch die Werkzeug-Angriffsflächen einen quer zur Schraubenachse liegenden Polygon- bzw. Mehrkant-Umriß haben und mit Abstand hinter einem an die Endfläche des Kopfteils anschließenden Rundquerschnitt liegen. In einem solchen Falle können die Schraubglieder ebenfalls nur von der Seite her, also bei geöffnetem Fenster oder geöffneter Tür mit Hilfe eines Maulschlüssels angezogen oder gelöst werden.According to claim 3, however, the tool engagement surfaces can also have a polygonal or polygonal outline lying transversely to the screw axis and be at a distance behind a round cross section adjoining the end face of the head part. In such a case, the screw members can likewise only be tightened or loosened from the side, that is to say with the window or door open, with the aid of a spanner.

Die erfindungsgemäße Ausgestaltung einer Befestigungsvorrichtung erhöht also die Einbruchsicherheit von damit ausgestatteten Fenstern, Türen od. dgl. beträchtlich.The design of a fastening device according to the invention thus considerably increases the security against break-in of windows, doors or the like equipped therewith.

Die Fig. 1 der Zeichnung zeigt ein in bekannter Weise aus einem Flügel 1 und einem feststehenden Rahmen 2 bestehendes Fenster oder eine Tür. Flügel 1 und feststehender Rahmen 2 sind dabei jeweils aus Metall- oder Kunststoffprofilen zusammengesetzt.Fig. 1 of the drawing shows a window or door existing in a known manner from a wing 1 and a fixed frame 2. Wing 1 and fixed frame 2 are each composed of metal or plastic profiles.

An der Falzseite des Flügels 1 ist in einer einseitig offenen, hinterschnittenen Kammer eine Treibstange 3 angeordnet, die zu einem Treibstangenbeschlag, beispielsweise einem Drehkippbeschlag und/oder einem Verschlußbeschlag, gehört.On the rebate side of the wing 1, a drive rod 3 is arranged in an undercut chamber which is open on one side and which belongs to a drive rod fitting, for example a tilt and turn fitting and / or a locking fitting.

Die Treibstange 3 wird mit Hilfe eines Bedienungshandgriffes 4 und eines - im einzelnen nicht gezeigten- Stellgetriebes bekannter Bauart bewegt. Diese Stellgetriebe kann beispielsweise in der Lagerrosette 5 für den Bedienungshandgriff 4 untergebracht sein und über einen Mitnehmerlappen 6 mit einer an der Treibstange 3 befestigten Kupplungsschlaufe 7 in Betätigungseingriff gebracht werden, wie das beispielsweise in Fig. 2 angedeutet ist.The drive rod 3 is moved with the aid of an operating handle 4 and a known type of actuating gear (not shown in detail). This actuating gear can, for example, be accommodated in the bearing rosette 5 for the operating handle 4 and via a driver tab 6 are brought into actuation engagement with a coupling loop 7 fastened to the drive rod 3, as is indicated, for example, in FIG. 2.

Die Lagerrosette 5 des Bedienungshandgriffs 4 ist an dem Profilholm des Flügels 1 von der Unterseite des Überschlag-Profilteils 1a aus mittels zweier Schraubglieder 8 befestigt, wie das der Fig. 2 entnommen werden kann. Diese Schraubglieder 8 sind dabei so angeordnet, daß sie eine von außen unsichtbare Lage einnehmen, wenn der Flügel 1 sich in Schließlage am feststehenden Rahmen 2 befindet, wie das deutlich der Fig. 1 zu entnehmen ist. Jedes der Schraubglieder 8 hat dabei einen Gewindeschaft 8a, der ein Durchgangsloch 9 im Überschlag-Profilteil 1a durchsetzt und in eine Gewindebohrung 10 der Lagerrosette 5 des Bedienungshandgriffs 4 eingreift. Darüberhinaus weisen die Schraubglieder 8 aber auch einen verdickten Kopfteil 8b auf, der sich an der Unterseite des Überschlag-Profilteils 1a entweder unmittelbar oder aber unter Benutzung zusätzlicher Zwischenplatten 11 und/oder von Federscheiben 12 abstützt.The bearing rosette 5 of the operating handle 4 is fastened to the profile spar of the wing 1 from the underside of the rollover profile part 1a by means of two screw members 8, as can be seen in FIG. 2. These screw members 8 are arranged so that they assume an invisible position from the outside when the sash 1 is in the closed position on the fixed frame 2, as can be clearly seen in FIG. 1. Each of the screw members 8 has a threaded shaft 8a, which passes through a through hole 9 in the rollover profile part 1a and engages in a threaded bore 10 of the bearing rosette 5 of the operating handle 4. In addition, the screw members 8 also have a thickened head part 8b, which is supported on the underside of the rollover profile part 1a either directly or using additional intermediate plates 11 and / or spring washers 12.

Nach den Fig. 1 bis 3 haben die Kopfteile 8b der Schraubglieder 8 jeweils kreisförmige Querschnittsform bzw. eine zylindrische Gestalt, während ihre vom Gewindeschaft 8a abgewendete Endfläche 8c eine konische Gestalt aufweist, wie das die Fig. 1 und 2 erkennen lassen.1 to 3, the head parts 8b of the screw members 8 each have a circular cross-sectional shape or a cylindrical shape, while their end face 8c facing away from the threaded shaft 8a has a conical shape, as can be seen in FIGS. 1 and 2.

Zumindest die Endfläche 8c des Kopfteils 8b der Schraubglieder 8 ist gehärtet ausgeführt oder auf andere Art und Weise mit einer Panzerbeschichtung versehen, die eine hohe Widerstandsfähigkeit gegen den Angriff von Zerspanungswerkzeugen aufweist.At least the end face 8c of the head part 8b of the screw members 8 is made hardened or in some other way provided with an armored coating which has a high resistance to the attack of cutting tools.

Die Werkzeug-Angriffsflächen zum Eindrehen und Anziehen sowie auch zum bedarfsweisen Lösen der Schraubglieder 8 werden nach den Fig. 1 bis 3 von einer Kreuzloch-Anordnung 13 im Kopfteil 8b gebildet, in die als Betätigungswerkzeug ein - nicht gezeigter - Stift jeweils radial eingeführt werden kann.The tool engagement surfaces for screwing in and tightening as well as for releasing the screw members 8 as required are formed according to FIGS. 1 to 3 by a cross hole arrangement 13 in the head part 8b, into which a pin (not shown) can be inserted radially as the operating tool .

Die Lage der Kreuzloch-Anordnung 13 im Kopfteil 8b der Schraubglieder 8 ist dabei so vorgesehen, daß das stiftförmige Betätigungswerkzeug auch an einem nach rückwärts abgewinkelten Flanschabschnitt 1b des Überschlag-Profilteils 1a vorbeigeführt werden kann, wenn der Flügel 1 relativ zum feststehenden Rahmen 2 in eine Öffnungslage gebracht wird.The position of the cross hole arrangement 13 in the head part 8b of the screw members 8 is provided so that the pin-shaped actuating tool can also be guided past a rearwardly angled flange section 1b of the rollover profile part 1a when the sash 1 relative to the fixed frame 2 in a Opening position is brought.

Durch begrenzte Winkeldrehungen der Schraubglieder 8 mittels des stiftförmigen Betätigungswerkzeuges können diese angezogen und bedarfsweise auch wieder gelöst werden.By limited angular rotations of the screw members 8 by means of the pin-shaped actuating tool, these can be tightened and, if necessary, also loosened again.

Befindet sich der Flügel 1 ihn Schließlage am feststehenden Rahmen 2 (Fig. 1) dann ist weder die Kreuzlock-Anordnung 13 im Kopfteil 8b der Schraubglieder 8 zugänglich, noch können die Schraubglieder 8b von außen her mit Zerspanungswerkzeugen zerstört werden. Da zumindest die Endflächen 8c der Kopfteile 8b an den Schraubgliedern 8 gehärtet oder mit einer Panzerbeschichtung versehen sind und darüberhinaus die Endflächen 8c auch eine konische Gestalt haben, wird ein von außen her hierauf zur Einwirkung gebrachtes Zerspanungswerkzeug hiervon abgleiten und damit eine Zerstörung bzw. Entfernung des Kopfteils 8b unmöglich machen.If the wing 1 is in its closed position on the fixed frame 2 (FIG. 1), then the cross lock arrangement 13 in the head part 8b of the screw members 8 is not accessible, and the screw members 8b cannot be destroyed from the outside with cutting tools. Since at least the end faces 8c of the head parts 8b are hardened on the screw members 8 or are provided with an armor coating and, moreover, the end faces 8c also have a conical shape, a cutting tool brought into action from the outside will slide away from them and thus destroy or remove the Make headboard 8b impossible.

Es ist nicht unbedingt notwendig, die Endfläche 8c am Kopfteil 8b der Schraubglieder 8 konisch zu gestalten. Sie kann vielmehr auch sphärisch, insbesondere halbkugelförmig, ausgeführt sein, wie das in Fig. 4 deutlich zu sehen ist.It is not absolutely necessary to design the end face 8c on the head part 8b of the screw members 8 to be conical. Rather, it can also be spherical, in particular hemispherical, as can be clearly seen in FIG. 4.

Fig. 4 zeigt aber auch, daß die Werkzeug-Angriffsflächen am Kopfteil 8b der Schraubglieder 8 nicht unbedingt durch eine Kreuzloch-Anordnung 13 gebildet werden müssen. Vielmehr können sie auch einen quer zur Schraubenachse liegenden Polygon- bzw. Mehrkant-Umriß 14 haben und dabei mit Abstand hinter einem von der Endfläche 8c umschriebenen Rundquerschnitt liegen. In diesem Falle lassen sich die Schraubglieder 8 mit Hilfe eines Maulschlüssels od. dgl. betätigen, indem dieser bei gegenüber dem feststehenden Rahmen 2 geöffnetem Flügel 1 am abgewinkelten Flanschabschnitt 1b des Überschlag-Profilteils 1a vorbeigeführt wird.4 also shows that the tool engagement surfaces on the head part 8b of the screw members 8 do not necessarily have to be formed by a cross hole arrangement 13. Rather, they can also have a polygonal or polygonal outline 14 lying transversely to the screw axis and thereby be at a distance behind a circular cross-section circumscribed by the end face 8c. In this case, the screw members 8 can be actuated with the aid of an open-ended wrench or the like, by guiding them past the angled flange section 1b of the rollover profile part 1a with the sash 1 open relative to the fixed frame 2.

Selbstverständlich ist auch bei der Ausführungsform der Schraubglieder 8 nach Fig. 4 die Endfläche 8c des Kopfteils 8b gehärtet ausgeführt oder auf andere Art und Weise mit einer gegen Zerspanungswerkzeuge widerstandsfähigen Panzerbeschichtung versehen.Of course, in the embodiment of the screw members 8 according to FIG. 4, the end face 8c of the head part 8b is also hardened or provided in another way with an armor coating that is resistant to cutting tools.

Den Fig. 1 bis 3 der Zeichnung ist noch zu entnehmen, daß mit Hilfe der Schraubglieder 8 auch zusätzliche Beschlagteile innerhalb des Freiraums zwischen den Falzflächen des Flügels 1 und des feststehenden Rahmens 2 befestigt werden können. Als entsprechendes Beschlagteil kann beispielsweise eine aus gehärtetem oder gepanzertem Material bestehende Abdeckkappe 15 vorgesehen werden, welche den Mitnehmerlappen 6 des Stellgetriebes und die Kupplungsschlaufe 7 der Treibstange 3 über ihren Bewegungsbereich hinweg abdeckt. Auch dieser Abdeckkappe 15 kann dabei an ihrer in Richtung der Außenseite des Fensters oder der Tür weisenden Endfläche mit einer abgeschrägten Fläche 15a versehen werden, die ein Abgleiten und Auslenken eines Zerspanungswerkzeuges bewirkt. Die Abdeckkappe 15 ist beim Ausführungsbeispiel nach den Fig. 1 bis 3 einstückig mit den Zwischenplatten 11 hergestellt, die vom Gewindeschaft 8a der Schraubglieder 8 durchsetzt und von deren Kopfteil 8b übergriffen werden.1 to 3 of the drawing it can still be seen that with the aid of the screw members 8, additional fitting parts can also be fastened within the free space between the folded surfaces of the wing 1 and the fixed frame 2. As a corresponding fitting part, for example, a cover cap 15 made of hardened or armored material can be provided, which covers the driver tab 6 of the actuating gear and the coupling loop 7 of the drive rod 3 over their range of motion. This cover cap 15 can also be provided on its end surface pointing in the direction of the outside of the window or the door with a beveled surface 15a, which causes a cutting tool to slide and deflect. In the exemplary embodiment according to FIGS. 1 to 3, the cover cap 15 is made in one piece with the intermediate plates 11, which are penetrated by the threaded shaft 8a of the screw members 8 and overlapped by the head part 8b thereof.

Im Zusammenhang mit dem Ausführungsbeispiel nach Fig. 4 sei noch darauf hingewiesen, daß der Polygon- bzw. Mehrkant-Umriß 14 am Kopfteil 8b im Bereich eines Umfangseinschnitts vorgesehen werden kann, dessen Breite so bemessen ist, daß ein Maulschlüssel mit Norm-Abmessungen nicht in diesen Einschnitt eingerückt werden kann. Zur Betätigung der Schraubglieder müßte dann vielmehr ein Spezial-Maulschlüssel in Benutzung genommen werden.In connection with the embodiment according to FIG. 4, it should also be pointed out that the polygon or polygonal outline 14 on the head part 8b can be provided in the region of a circumferential incision, the width of which is dimensioned such that an open-ended spanner with standard dimensions is not in this incision can be indented. A special open-end wrench would then have to be used to actuate the screw links.

Obwohl vorstehend der Einstaz der Befestigungsvorrichtung nur in Verbindung mit der Lagerrosette für den Bedienungshandgriff eines Stellgetriebes sowie mit einer Anbohrschutzkappe erläutert wurde, ist diese natürlich auch für die Benutzung in Verbindung mit anderen Beschlägen geeignet. Sie kann beispielsweise auch für Scharniere der durch die DE-OS 22 50 797 und die DE-OS 25 24 268 bekannt gewordenen Art benutzt werden.Although the use of the fastening device was only explained above in connection with the bearing rosette for the operating handle of an actuating gear and with a drilling protection cap, this is of course also suitable for use in connection with other fittings. It can also be used, for example, for hinges of the type known from DE-OS 22 50 797 and DE-OS 25 24 268.
