Description

Die Erfindung betrifft ein Beschlagteil für Türen oder Fenster zur Aufnahme eines Bedienorgans mit einem Ober- und einem Unterteil aus verschiedenen Werkstoffen.The invention relates to a fitting part for doors or windows for receiving an operating element with an upper and a lower part made of different materials.

Solche Beschlagteile werden als Türschilde, Schloßblech Fensteroliven oder dergleichen, direkt an einer Tür oder einem Fenster angebracht (z.B. das Dokument DE-U- 7 028 712). Sie dienen der Aufnahme eines Bedienorgans, z.B. eines Türdrückers, einer Klinke, eines Kipphebels, sowie gegebenenfalls eines Schließzylinders. Im Hinblick insbesondere auf Gebrauchstauglichkeit ist es wichtig, daß solche Beschlagteile stabil ausgeführt sind. Zugleich sollen die Oberflächen glatt, gegebenenfalls auch glänzend sein, um eine leichte Reinigung zu gewährleisten und optisch ansprechende Gestaltungen zu ermöglichen.Such fitting parts are attached as door shields, lock plates, window olives or the like, directly to a door or a window (for example document DE-U-7 028 712). They are used to hold an operating element, such as a door handle, a latch, a rocker arm, and possibly a locking cylinder. With regard to suitability for use in particular, it is important that such fitting parts are designed to be stable. At the same time, the surfaces should be smooth, possibly also glossy, in order to ensure easy cleaning and to enable visually appealing designs.

Es ist bekannt, Türschilde zweiteilig mit einem Metallunterteil und einer Abdeckung aus Kunststoff auszuführen. Hierbei kann durch das Metallunterteil eine gute Stabilität erreicht und mit der Abdeckung aus Kunststoff die gewünschte Oberflächenbeschaffenheit realisiert werden. Diese bekannten Türschilde weisen jedoch eine relativ große Breite auf und es können Probleme bei der Befestigung der Abdeckung auf dem Metallunterteil auftreten, da ein gleichmäßiges Anliegen der Abdeckung über deren gesamte Ausdehnung nicht immer gegeben ist. Die Breite des Türschildes läßt sich nicht beliebig verkleinern. Dem sind Grenzen gesetzt beispielsweise durch den für das Bedienorgan notwendigen Durchbruch, der von einer ausreichend großen Wandstärke am Beschlagteil umgeben sein muß, um die Lagerkräfte aufnehmen zu können und Rißbildungen im Beschlagteil zu vermeiden. Auf der anderen Seite besteht vielfach das Bedürfnis, sei es aus Platzgründen, konstruktiven oder ästhetischen Gründen, das Türschild möglichst schmal zu halten.It is known to design door plates in two parts with a metal lower part and a cover made of plastic. Good stability can be achieved through the metal lower part and the desired surface texture can be achieved with the plastic cover. However, these known door plates have a relatively large width and problems can arise when fastening the cover to the metal lower part, since the cover does not always lie evenly over its entire extent. The width of the door sign cannot be reduced arbitrarily. Limits are set, for example, by the opening required for the operating element, which must be surrounded by a sufficiently large wall thickness on the fitting part in order to be able to absorb the bearing forces and to avoid cracking in the fitting part. On the other hand, there is often a need to keep the door plate as narrow as possible, be it for reasons of space, construction or aesthetics.

Demgemäß liegt der Erfindung die Aufgabe zugrunde, ein Beschlagteil der oben genannten Art zu schaffen, das eine kompakte Bauweise bei hoher Stabilität ermöglicht und ein sicheres Anliegen des Oberteils gewährleistet.Accordingly, the invention has for its object to provide a fitting part of the type mentioned above, which enables a compact design with high stability and ensures a secure fit of the upper part.

Die Aufgabe wird durch ein Beschlagteil gemäß dem Anspruch 1 gelöst. Die Ausbildung als Verbundbauteil ermöglich eine sehr kompakte, stabile Bauweise, wobei zwangsläufig eine satte Anlage des Oberteils am Unterteil gewährleistet ist.The object is achieved by a fitting part according to claim 1. The training as a composite component enables a very compact, stable construction, inevitably ensuring a tight fit of the upper part on the lower part.

Eine einfache Herstellung ergibt sich dadurch, daß das Unterteil aus Kunststoff im Spritzgießverfahren hergestellt ist.A simple manufacture results from the fact that the lower part is made of plastic by injection molding.

Um eine gute Stabilität zu erreichen, ist vorgesehen, daß das Unterteil aus einem glasfaser- und/oder keramikverstärkten Kunststoff besteht. Dabei ist insbesondere vorgesehen, daß das Unterteil aus glasfaserverstärktem Polyamid besteht, das gute Lagereigenschaften, bei gleichzeitig geringem Verschleiß aufweist. Vorzugsweise ist ein Glasfaseranteil von 30 % vorgesehen.In order to achieve good stability, it is provided that the lower part consists of a glass fiber and / or ceramic reinforced plastic. In particular, it is provided that the lower part consists of glass fiber reinforced polyamide, which has good storage properties with little wear. A glass fiber content of 30% is preferably provided.

Um ein stabiles Beschlagteil bei geringem Materialeinsatz zu schaffen, ist vorgesehen, daß das Unterteil als Rippenkonstruktion ausgebildet ist. Diese Ausführung bringt außerdem den Vorteil, daß bei Verwendung eines Kunststoffs zur Herstellung des Unterteils ein sehr gleichmäßiger Schrumpfprozeß beim Abkühlen gegeben ist und das Unterteil form- und maßhaltig bleibt.In order to create a stable fitting part with little use of material, it is provided that the lower part is designed as a rib construction. This design also has the advantage that when using a plastic for the production of the lower part there is a very uniform shrinking process when cooling and the lower part remains true to size and dimension.

Eine dauerhafte Verbindung des Oberteils und des Unterteils ergibt sich dadurch, daß das Unterteil im Spritzgießverfahren durch das Oberteil umspritzt ist.A permanent connection of the upper part and the lower part results from the fact that the lower part is extrusion-coated by the upper part.

Um eine gleichmäßige Oberflächenbeschaffenheit des Beschlagteils zu erzielen, ist vorgesehen, daß das Oberteil die Sichtseiten des Beschlagteils bildet.In order to achieve a uniform surface quality of the fitting part, it is provided that the upper part forms the visible sides of the fitting part.

Um eine sehr dauerhafte Lagerung eines Bedienorgans zu erreichen, ist vorgesehen, daß das Unterteil eine Lagerbuchse für das Bedienorgan aufweist. Da das Unterteil aus einem Material guter Stabilität, z.B. armierten Polyamid, hergestellt ist, ist davon auszugehen, daß diese Ausführung der Lagerbuchse eine sehr verschleißfreie Lagerung ermöglicht. Dabei ist insbesondere vorgesehen, daß die Lagerbuchse des Unterteils in das Oberteil eingreift, dieses gegebenenfalls auch durchgreift. Da das Bedienorgan im allgemeinen mit einem Ringflansch an der Sichtseite zur Anlage an das Beschlagteil kommt, ergibt sich eine sehr verschleißfeste Ausführung.In order to achieve a very permanent storage of an operating element, it is provided that the lower part has a bearing bush for the operating element. Since the lower part is made of a material of good stability, for example reinforced polyamide, it can be assumed that this design of the bearing bush enables very wear-free storage. In particular, it is provided that the bearing bush of the lower part engages in the upper part, possibly also reaching through it. Because the control panel generally comes into contact with the fitting part with an annular flange on the visible side, this results in a very wear-resistant design.

Um optisch saubere Abschlüsse bei sichtbaren Durchdringungen des Beschlagteils zu realisieren, ist insbesondere für einen Schließzylinder vorgesehen, daß das Unterteil eine schlüssellochförmige Ausnehmung aufweist, die im wesentlichen vom Material des Oberteils ausgekleidet ist.In order to achieve optically clean finishes with visible penetrations of the fitting part, it is provided in particular for a locking cylinder that the lower part has a keyhole-shaped recess which is essentially lined with the material of the upper part.

Um eine verdeckte Befestigung des Beschlagteils zu ermöglichen, ist vorgesehen, daß das Oberteil zumindest eine rastbare Abdeckkappe für ein darunter liegendes Befestigungsmittel aufweist. Hierbei können herkömmliche Befestigungsmittel, wie Schrauben, Nägel, Bolzen oder dergleichen eingesetzt werden.In order to enable a concealed fastening of the fitting part, it is provided that the upper part has at least one latchable cover cap for a fastening means lying underneath. Conventional fasteners such as screws, nails, bolts or the like can be used here.

Um ein sattes Anliegen des Beschlagteils auf seiner gesamten Länge zu gewährleisten ist vorgesehen, daß das Oberteil an jedem Ende eine aufrastbare Abdeckkappe für je ein Befestigungsmittel aufweist, um das Beschlagteil an jedem Ende zu befestigen.In order to ensure a tight fit of the fitting part over its entire length, it is provided that the upper part has a snap-on cover cap for each fastening means at each end in order to fasten the fitting part at each end.

In bevorzugter Ausführung ist vorgesehen, daß an den Enden des Beschlagteils je eine Bohrung für ein Befestigungsmittel vorgesehen ist, die jeweils von einer Abdeckkappe abgedeckt ist, um eine stabile und universelle Befestigung zu ermöglichen.In a preferred embodiment it is provided that a bore for a fastener is provided at the ends of the fitting part, each of which is covered by a cover cap in order to enable a stable and universal fastening.

Gerade bei Verwendung von selbstschneidenden Schrauben ist es vorteilhaft, wenn die Bohrung von einer am Oberteil angeformten, das Unterteil durchgreifenden Hülse gebildet ist, da diese dann aus dem im allgemeinen weniger festen Material des Oberteils besteht.Especially when using self-tapping screws, it is advantageous if the bore is formed by a sleeve formed on the upper part and penetrating the lower part, since this then consists of the generally less strong material of the upper part.

Dabei kann es insbesondere günstig sein, wenn die Hülse das Unterteil rückseitig überragt, da dann zwei auf gegenüberliegenden Seiten einer Tür oder eines Fensters angeordnete Beschlagteile mittels Steckschrauben verbunden werden können und die Hülsen durch Eingriff in Bohrungen an der Tür oder dem Fenster für eine einwandfreie Positionierung der Beschlagteile sorgen.It can be particularly advantageous if the sleeve projects beyond the rear of the lower part, since then two fitting parts arranged on opposite sides of a door or a window can be connected by means of plug-in screws and the sleeves by engaging holes in the door or the window for perfect positioning of the hardware components.

Um ein formschönes Beschlagteil zu schaffen, ist in bevorzugter Ausführung vorgesehen, daß dessen Breite kleiner als 29 mm ist.In order to create an elegant fitting part, a preferred embodiment provides that its width is less than 29 mm.

Im folgenden wird die Erfindung anhand der Zeichnung eines Ausführungsbeispiels näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to the drawing of an exemplary embodiment. Show it:

Figure 2

In Figur 1 ist ein als Verbundbauteil 1 ausgeführtes Türschild mit einem Oberteil 2 und einem Unterteil 3 dargestellt. Hierbei besteht das Unterteil aus einem glasfaserverstärkten Polyamid und das Oberteil aus einem sehr glatte Kunststoff, z.B. Polystyrol, Polypropylen, Polyamid oder dergleichen. In einem zweiten Spritzvorgang wurde das in der Oberteilform fixierte Unterteil vom Oberteil-Material umspritzt.FIG. 1 shows a door plate designed as a composite component 1 with an upper part 2 and a lower part 3. The lower part consists of a glass fiber reinforced polyamide and the upper part of a very smooth plastic, such as polystyrene, polypropylene, polyamide or the like. In a second injection process, the lower part fixed in the upper part shape was overmolded with the upper part material.

Das Beschlagteil 1 weist eine Lagerbuchse 4 zur Aufnahme eines Bedienorgans, wie eines Türdrückers oder Türknaufs, auf. Die Lagerbuchse 4 ist am Unterteil 3 ausgebildet, so daß eine dauerhafte und stabile Lagerung eines Bedienorgans gewährleistet ist. Dabei durchragt die Lagerbuchse 4 das Oberteil 2, so daß eine Stirnseite 6 der Lagerbuchse als Axialanschlag für das Bedienorgan dienen kann, der so auch aus dem stabilen Material des Unterteils 3 gebildet ist. Das Oberteil 2 bildet einen koaxialen Kreisring 7 um die Lagerbuchse 4, der plan mit der Stirnseite 6 abschließt. Hierdurch wird eine optische Verblendung im Bereich des Überganges Bedienorgan/Lagerbuchse 4 gewährleistet. In Figur 2 ist in der Draufsicht die koaxiale Anordnung der Stirnfläche 6 der Lagerbuchse 4, gebildet aus dem Material des Unterteils 3, und dem Kreisring 7 des Oberteils 2 zu erkennen. Ein entgegengerichteter Axialanschlag wird durch einen Ringflansch 18 der Lagerbuchse 4 gebildet. Hier läßt sich ein mit einem Spreizkern mit dem Flansch hintergreifenden Nasen versehenes Bedienorgan, wie ein Griff, in Axialrichtung fixieren. Der Spreizkern kann dabei so ausgebildet sein, daß er mit der rückseitigen Aufschraubfläche des Beschlagteils 1 abschließt.The fitting part 1 has a bearing bush 4 for receiving an operating element, such as a door handle or doorknob. The bearing bush 4 is formed on the lower part 3, so that a permanent and stable mounting of an operating member is ensured. The bearing bush 4 projects through the upper part 2, so that an end face 6 of the bearing bush can serve as an axial stop for the operating element, which is also formed from the stable material of the lower part 3. The upper part 2 forms a coaxial circular ring 7 around the bearing bush 4, which ends flush with the end face 6. This ensures an optical veneer in the area of the transition from control element to bearing bush 4. FIG. 2 shows the top view of the coaxial arrangement of the end face 6 of the bearing bush 4, formed from the material of the lower part 3, and the circular ring 7 of the upper part 2. An opposing axial stop is formed by an annular flange 18 of the bearing bush 4. Here, an operating element, such as a handle, provided with an expanding core with lugs engaging behind the flange, can be fixed in the axial direction. The expanding core can be designed so that it closes with the rear screw-on surface of the fitting part 1.

An beiden Enden des Beschlagteils 1 ist jeweils eine rastbar aufsteckbare Abdeckkappe 11 aus dem Material des Oberteils 2 vorgesehen. Am unteren Ende des Beschlagteils 1 in Figur 1 - links - ist die Abdeckkappe 11 aufgesteckt und im Schnitt dargestellt. Die Abdeckkappe 11 überdeckt eine Bohrung 12, deren Wandung durch eine an das Oberteil 2 angeformte Hülse 13 gebildet ist. Das obere Ende des Beschlagteils 1 - rechts in Figur 1 - ist ohne Abdeckkappe 11 dargestellt. Auch in den Endbereich der Abdeckkappen 11 ist das Unterteil 3 vom Oberteil 2 bis auf die Rückseite 3a überdeckt. Dadurch ergibt sich ein sehr einfaches Spritzgießen, da das Oberteil 2 direkt auf das Unterteil 3 ohne Verwendung einer Maske aufgespritzt werden kann. Zudem ergibt sich ein stabiler Verbund von Ober- und Unterteil. Dieser wird insbesondere dadurch verstärkt, daß an der Rück- oder Unterseite 3a des Unterteils 3 die seitlichen Kanten 3c des Unterteils gegenüber der Anlagefläche der Unterseite 3a zurückversetzt sind. Hierdurch können die Kanten 3c des Unterteils 3 vom Material des Oberteils 2 umgriffen sein. Zusätzlich können in den Randbereichen der Unterseiten 3a noch Nuten 3d ausgebildet sein, in die das Material des Oberteils 2 eingreift, so daß es das Unterteil 3 praktisch umklammert.At both ends of the fitting part 1 there is a snap-on cover cap 11 made of the material of the upper part 2. At the lower end of the fitting part 1 in FIG. 1 - on the left - the cover cap 11 is attached and shown in section. The cover cap 11 covers a bore 12, the wall of which is formed by a sleeve 13 molded onto the upper part 2. The upper end of the fitting part 1 - on the right in FIG. 1 - is shown without a cap 11. The lower part 3 is also covered from the upper part 2 to the rear 3a in the end region of the covering caps 11. This results in a very simple injection molding, since the upper part 2 directly onto the lower part 3 Can be sprayed on using a mask. In addition, there is a stable bond between the upper and lower part. This is particularly reinforced by the fact that on the rear or underside 3a of the lower part 3 the lateral edges 3c of the lower part are set back relative to the contact surface of the underside 3a. As a result, the edges 3c of the lower part 3 can be encompassed by the material of the upper part 2. In addition, grooves 3d can also be formed in the edge regions of the undersides 3a, into which the material of the upper part 2 engages, so that it practically clasps the lower part 3.

Die Abdeckkappe 11 ist so gestaltet, daß sie einen bündigen Abschluß zum Oberteil 2 bildet, wie in Figur 2 zu erkennen ist, wobei lediglich aus ästhetischen Gründen eine Rille 19 an der Kante des Oberteils 2 zur Abdeckkappe 11 vorgesehen ist. Um ein Abrutschen der Abdeckkappe 11 zu verhindern, sind im Endbereich der Abdeckkappen 11 Ausnehmungen 16 vorgesehen, in die entsprechende Stege der Abdeckkappen 11 eingreifen. An der Abdeckkappe 11 sind Rastnasen 17 angeordnet (vergleiche Figur 3), die die Endbereiche des Beschlagteils 1 im eingerasteten Zustand teilweise umfassen und in entsprechende Ausnehmungen des Unterteils 3 eingreifen. Dadurch wird ein sicheres Einrasten der Abdeckkappen 11 am Beschlagteil 1 gewährleistet.The cover cap 11 is designed such that it forms a flush closure to the upper part 2, as can be seen in FIG. 2, a groove 19 being provided on the edge of the upper part 2 for the cover cap 11 only for aesthetic reasons. In order to prevent the cover cap 11 from slipping, recesses 16 are provided in the end region of the cover caps, into which corresponding webs of the cover caps 11 engage. Lugs 17 are arranged on the cover cap 11 (see FIG. 3), which partially enclose the end regions of the fitting part 1 in the engaged state and engage in corresponding recesses in the lower part 3. This ensures that the cover caps 11 engage securely on the fitting part 1.

Das Beschlagteil 1 weist eine Ausnehmung 8, zur Aufnahme eines Schließzylinders, wie eines Profilzylinders, aus. In Figur 3 ist die Auskleidung der Wandung 9 der Ausnehmung 8 durch das Oberteil 2 erkennbar. Hierdurch wird frontseitig ein gerundeter Kantenverlauf zur Ausnehmung 8 gewährleistet. Da das Unterteil beim Aufspritzen des Oberteils 2 bevorzugt von der Frontseite aus gehalten wird, ist vorgesehen, daß ein Bolzen mit einem die Stirnseite 6 der Lagerbuchse 4 überdeckenden Ringflansch zum Halten verwendet wird. Zur Fixierung des Unterteils in der Oberteilform dient zunächst ein Aufnahmestift in der Lagerbuchse 4, wobei die Kontur des Aufnahmestiftes der der Lagerbuchse entspricht. Ein entsprechender Lagerstift kann in der Ausnehmung 8 angeordnet sein, wobei er hier nur an Nasen 8a des Unterteils 3 angreift, während der restliche Zwischenraum zwischen diesem Profilstift und dem Unterteil 4 beim Spritzen des Oberteils durch dessen Material ausgefüllt wird. Weiterhin können je zwei Haltestifte in den Bereichen der Abdeckkappen (wie 11) am Unterteil angreifen (bei 3a). Schließlich kann ein Haltering, wie ein Band am oben erstgenannten Aufnahmestift, auf die Stirnfläche 6 der Lagerbuchse 4 drücken. Durch beide Maßnahmen wird das Unterteil mit seiner Unterseite 3b plan auf die Unterseite der Oberteilform gedrückt.The fitting part 1 has a recess 8 for receiving a locking cylinder, such as a profile cylinder. In Figure 3, the lining of the wall 9 of the recess 8 through the upper part 2 can be seen. This ensures a rounded edge profile to the recess 8 at the front. Since the lower part is preferably held from the front when the upper part 2 is sprayed on, it is provided that a bolt with an annular flange covering the end face 6 of the bearing bush 4 is used for holding. For Fixing the lower part in the upper part shape first serves a locating pin in the bearing bush 4, the contour of the locating pin corresponding to that of the bearing bush. A corresponding bearing pin can be arranged in the recess 8, in which case it only engages lugs 8a of the lower part 3, while the remaining space between this profiled pin and the lower part 4 is filled by the material when the upper part is sprayed. Furthermore, two retaining pins can engage in the areas of the cover caps (such as 11) on the lower part (in FIG. 3a). Finally, a retaining ring, such as a band on the above-mentioned receiving pin, can press onto the end face 6 of the bearing bush 4. By both measures, the lower part 3b is pressed flat onto the underside of the upper part shape.

In Figur 3 sind Rippen 14 dargestellt, die dem Unterteil 2 die notwendige Stabilität bei möglichst großer Materialeinsparung verleihen.FIG. 3 shows ribs 14 which give the lower part 2 the necessary stability with the greatest possible material savings.

Das dargestellte Beschlagteil 1 zeichnet sich durch eine außerordentlich hohe Stabilität bei minimaler Breite von 24,5 mm aus. Durch Verwendung entsprechender Kunststoffe für das Oberteil 2 und die Abdeckkappen 11, bei denen auf die Stabilität keine besondere Rücksicht genommen werden muß, ist eine sehr ansprechende Gestaltung des Beschlagteils möglich, wobei sich insbesondere sehr glatte, leicht zu reinigende Oberflächen ergeben.The fitting part 1 shown is characterized by an extraordinarily high stability with a minimum width of 24.5 mm. By using appropriate plastics for the upper part 2 and the cover caps 11, in which no particular consideration has to be given to the stability, a very appealing design of the fitting part is possible, which results in very smooth, easy-to-clean surfaces.
