Description

Die Erfindung betrifft einen Arm, insbesondere Scherenarm, für eine Beschlaganordnung eines Fensters, einer Tür oder dergleichen.The invention relates to an arm, in particular a scissor arm, for a fitting arrangement of a window, a door or the like.

Gewisse Scharnierkonstruktionen bei Dreh- und Dreh-Kipp-Fenstern haben das Ziel einer speziellen gesteuerten Ausdrehbewegung des Flügels. Diese Scharnierkonstruktionen sind im ungeöffneten Flügelzustand für den Bediener in der Regel nicht sichtbar. Die spezielle Mechanik bewirkt, dass der Flügel ohne wesentlichen Raumbedarf neben dem Scharnierbereich aufdrehen kann. Damit ist es zum Beispiel möglich, das Mauerwerk sehr nahe an einen Flügel heranzuführen, was zum Beispiel für eine schmale sichtbare Breite des Blendrahmens oder für die seitliche Anbringung von Rollladengurtaufwicklern vorteilhaft ist.Certain hinge constructions in turn and tilt and turn windows have the goal of a special controlled turning movement of the sash. These hinge constructions are usually not visible to the operator when the sash is not open. The special mechanism ensures that the sash can open next to the hinge area without taking up any significant space. This makes it possible, for example, to bring the masonry very close to a wing, which is advantageous, for example, for a narrow visible width of the window frame or for the lateral attachment of roller shutter belt winders.

Solche Scharnierkonstruktionen bestehen in der Regel aus mehreren relativ zueinander bewegbaren Scherenarmen und Scherenverbindungen, welche zusätzlich die Last des Flügels auf den Rahmen übertragen.Such hinge constructions usually consist of several scissor arms and scissor connections that can be moved relative to one another, which additionally transmit the load of the sash to the frame.

Aus der GB 2 365 917 A ist ein Scherenarm bekannt, der zwei Armteile aufweist, die unter Bildung eines Zwischenraums miteinander verbunden sind. Im Bereich des Zwischenraums weist einer der Armteile eine schlitzartige Öffnung auf.From the GB 2 365 917 A a scissor arm is known which has two arm parts which are connected to one another with the formation of a space. In the area of the gap, one of the arm parts has a slot-like opening.

In der DE 39 15 796 A1 ist eine Ausstellvorrichtung für Dreh-/Kippflügel offenbart. Ein Arm weist einen Verriegelungsschlitz auf. Zur Verstärkung des Verriegelungsschlitzes ist eine Riegelplatte vorgesehen, die abgekröpft ist und im Bereich des Schlitzes einen Abstand zu dem Arm aufweist.In the DE 39 15 796 A1 a deployment device for turn / tilt sash is disclosed. One arm has a locking slot. To reinforce the locking slot, a locking plate is provided which is cranked and is at a distance from the arm in the area of the slot.

Aus der CA 2 374 890 C ist ein Arm bekannt, dessen Seiten umgefaltet sind und parallel zu einem Hauptbestandteil des Arms verlaufen. Die umgefalteten Teile weisen einen Abstand zum Hauptbestandteil auf.From the CA 2,374,890 C an arm is known whose sides are folded over and run parallel to a main component of the arm. The folded parts are at a distance from the main component.

Aus der EP 1 788 175 A1 ist eine Laschenanordnung eines Fensters bekannt, die zumindest zwei Laschen aufweist, wobei im Überlappungsbereich der Laschen wenigstens eine Schmiermittelabgabeeinrichtung angeordnet ist.From the EP 1 788 175 A1 a tab arrangement of a window is known which has at least two tabs, at least one lubricant dispensing device being arranged in the overlapping area of the tabs.

Aufgrund der zum Teil schweren Flügel und der ungünstigen Art und Weise der Lastübertragung über lange Arme und Hebel ergeben sich hohe Reibbelastungen, insbesondere auf die Gleitflächen der Verbindungen der Scherenarme. Zudem wird durch die während eines Hausbaus und während der üblichen Lebenszeit der Scharniere wirkende äußere Verschmutzung und die damit verbundene Beeinträchtigung und Abtragung der Schmierung die Reibung und Abnutzung der Scharnierarme stark erhöht.Because of the sometimes heavy wings and the unfavorable way in which the load is transmitted via long arms and levers, there are high frictional loads, in particular on the sliding surfaces of the connections between the scissor arms. In addition, the external soiling that occurs during the construction of a house and during the normal life of the hinges and the associated impairment and removal of the lubrication greatly increases the friction and wear of the hinge arms.

Aufgabe der vorliegenden Erfindung ist es daher, diesbezüglich Abhilfe zu schaffen.The object of the present invention is therefore to provide a remedy in this regard.

Gelöst wird diese Aufgabe erfindungsgemäß durch einen Arm, insbesondere Scherenarm, für eine Beschlaganordnung eines Fensters, einer Tür oder dergleichen, wobei der Arm zumindest zwei Materiallagen aufweist, wobei in der unteren Materiallage ein Durchbruch vorgesehen ist, der nach oben hin von einer oberen Materiallage abgedeckt ist, wobei die Materiallagen aus unterschiedlichen Werkstoffen ausgebildet sind. Die obere Materiallage deckt den Durchbruch somit vollständig ab und schützt diese vor von oben kommendem Schmutz. Zusätzlich wird die Schmierung in dem Durchbruch gekapselt. Der erfindungsgemäße Arm wird somit aus zumindest zwei paarweise zueinander liegenden und konturgleichen bzw. konturähnlichen Armteilen (Sandwichaufbau) aufgebaut, wobei in einem Armteil ein Durchbruch ausgebildet ist. Es versteht sich, dass auch mehr als zwei Materiallagen bzw. übereinander liegende Armteile verwendet werden können.This object is achieved according to the invention by an arm, in particular a scissor arm, for a fitting arrangement of a window, a door or the like, the arm having at least two material layers, an opening being provided in the lower material layer, which is covered by an upper material layer at the top is, wherein the material layers are formed from different materials. The upper material layer thus completely covers the opening and protects it from dirt coming from above. In addition, the lubrication is encapsulated in the opening. The arm according to the invention is thus built up from at least two arm parts of the same shape or similar shape (sandwich structure) lying in pairs with one another, with an opening being formed in one arm part. It goes without saying that more than two material layers or arm parts lying one above the other can also be used.

Weitere Vorteile ergeben sich, wenn der Durchbruch als Steuerungs- oder Führungskontur für ein weiteres Bauteil ausgebildet ist. Beispielsweise kann ein Zapfen, der an einem anderen Arm angeordnet ist, in dem Durchbruch angeordnet und dort geführt werden. Insbesondere kann der Durchbruch als Kontur für eine translatorische Bewegungsführung ausgebildet sein. Beispielsweise kann der Durchbruch als Langloch für einen Gleitbolzen oder ein Gleitstück ausgebildet sein. Weiterhin ist es denkbar, dass ein Bolzen drehbar in dem Durchbruch gelagert ist. Dadurch, dass die obere Materiallage den Durchbruch von oben her abdeckt, ist es nicht möglich, dass Schmutz von oben in die Führungskontur eintritt. Außerdem ist der Arm optisch ansprechender, da für einen Betrachter die Führung und das Schmiermittel in der Führung nicht sichtbar sind.Further advantages result if the opening is designed as a control or guide contour for a further component. For example, a pin which is arranged on another arm, in the Arranged breakthrough and guided there. In particular, the opening can be designed as a contour for translational movement guidance. For example, the opening can be designed as an elongated hole for a sliding bolt or a sliding piece. Furthermore, it is conceivable that a bolt is rotatably mounted in the opening. Because the upper material layer covers the opening from above, it is not possible for dirt to enter the guide contour from above. In addition, the arm is visually more appealing because the guide and the lubricant in the guide are not visible to a viewer.

Besondere Vorteile ergeben sich, wenn der Durchbruch als Schmiermitteldepot ausgebildet ist. Dadurch, dass der Durchbruch von oben her abgedeckt ist, ist die Schmierung so gekapselt, dass diese nicht übermäßig abgetragen wird. Gleitflächen, die sich unterhalb des Arms befinden, sind vor äußerer Verschmutzung optimal geschützt.Particular advantages arise if the opening is designed as a lubricant depot. Because the opening is covered from above, the lubrication is encapsulated in such a way that it is not excessively worn away. Sliding surfaces, which are located below the arm, are optimally protected from external contamination.

Gemäß einer bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, dass an der Unterseite der oberen Materiallage im Bereich des Durchbruchs der unteren Materiallage eine Ausnehmung vorgesehen ist, die dem Durchbruch im Wesentlichen entsprechen kann. Dadurch kann die Auflagefläche für ein Führungselement, wie beispielsweise einen Gleitbolzen oder ein Gleitstück, erhöht werden. Beispielsweise kann die Ausnehmung eingeprägt werden, ohne dabei aber einen Durchbruch in der oberen Materiallage zu erzeugen. Durch diese Maßnahme können die wirkenden Reibflächen vergrößert werden, um dadurch die Flächenpressung zu reduzieren.According to a preferred embodiment of the invention it can be provided that a recess is provided on the underside of the upper material layer in the area of the opening in the lower material layer, which recess can essentially correspond to the opening. As a result, the contact surface for a guide element, such as a slide bolt or a slide piece, can be increased. For example, the recess can be embossed without, however, producing an opening in the upper material layer. This measure enables the effective friction surfaces to be enlarged in order to thereby reduce the surface pressure.

Weitere Vorteile der Erfindung ergeben sich, wenn zumindest eine der Materiallagen eine verschleißarme Oberflächen- oder Materialbehandlung aufweist. Dadurch kann die vorhandene Reibbelastung gemindert werden. Die Verschleißfestigkeit des Arms kann durch die Oberflächen- oder Materialbehandlung erhöht werden. Außerdem können durch die Oberflächen- oder Materialbehandlung die Gleiteigenschaften verbessert werden und Reibung reduziert werden.Further advantages of the invention result if at least one of the material layers has a low-wear surface or material treatment having. This can reduce the existing frictional load. The arm's resistance to wear can be increased by the surface or material treatment. In addition, the surface or material treatment can improve the sliding properties and reduce friction.

Weiterhin ist es vorteilhaft, wenn die Materiallagen an einer oder mehreren Stellen spielfrei miteinander verbunden sind. Dadurch kann die Steifigkeit des Arms erhöht werden. Insbesondere können die Materiallagen an mehreren Stellen über die gesamte Länge des Arms spielfrei miteinander verbunden werden, um die Biegesteifigkeit zu erhöhen. Die Materiallagen können durch Nieten und/oder Schweißpunkte miteinander verbunden werden. Dabei können bestehende (ohnehin vorhandene bzw. benötigte) oder zusätzliche Vernietungen und/oder Schweißungen verwendet werden. Vorteilhafterweise sind die Materiallagen über die gesamte Länge des Arms an mehreren Stellen spielfrei miteinander verbunden.Furthermore, it is advantageous if the material layers are connected to one another without play at one or more points. This can increase the rigidity of the arm. In particular, the material layers can be connected to one another without play at several points over the entire length of the arm in order to increase the flexural rigidity. The material layers can be connected to one another by rivets and / or welding points. Existing (already existing or required) or additional rivets and / or welds can be used. The material layers are advantageously connected to one another without play at several points over the entire length of the arm.

Erfindungsgemäß sind die Materiallagen aus unterschiedlichen Werkstoffen ausgebildet. Dadurch kann der Arm optimal an den vorgesehenen Einsatzzweck angepasst werden. Beispielsweise können die Materiallagen aus unterschiedlichen Arten von Stahl ausgebildet sein. Zum Beispiel kann die obere Materiallage aus Edelstahl ausgebildet sein. Je nach Materialwahl können die Gleiteigenschaften der Ober- oder Unterseite des Arms verbessert werden.According to the invention, the material layers are made from different materials. This allows the arm to be optimally adapted to the intended use. For example, the material layers can be formed from different types of steel. For example, the upper material layer can be made of stainless steel. Depending on the choice of material, the sliding properties of the upper or lower side of the arm can be improved.

Weiterhin ist es denkbar, dass die obere Materiallage aus Kunststoff ausgebildet ist. Dadurch ist es möglich, den Arm besonders kostengünstig herzustellen.It is also conceivable that the upper material layer is made of plastic. This makes it possible to manufacture the arm particularly inexpensively.

In den Rahmen der Erfindung fällt außerdem ein Scherenlager mit einem erfindungsgemäßen Arm, wobei der Arm an einer Koppelstelle mit einem weiteren Arm gekoppelt ist und an der Koppelstelle zwischen den Armen eine Gleitzwischenlage vorgesehen ist. Beispielsweise kann die Gleitzwischenlage scheibenförmig ausgebildet sein und aus Kunststoff oder Edelstahl hergestellt sein. Dadurch kann die Reibung zwischen zwei Armen reduziert werden.The scope of the invention also includes a scissor bearing with an arm according to the invention, the arm being coupled to a further arm at a coupling point and a sliding intermediate layer being provided at the coupling point between the arms. For example, the sliding liner can be disk-shaped and made of plastic or stainless steel. This can reduce the friction between two arms.

In den Rahmen der Erfindung fällt außerdem ein Ecklager mit einem erfindungsgemäßen Arm.A corner bearing with an arm according to the invention also falls within the scope of the invention.

Weiterhin fällt in den Rahmen der Erfindung ein Fenster, eine Tür oder dergleichen mit einer Beschlaganordnung, die einen erfindungsgemäßen Arm aufweist.A window, a door or the like with a fitting arrangement which has an arm according to the invention also falls within the scope of the invention.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels.Further features and advantages of the invention emerge from the following description of an exemplary embodiment.

Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird nachfolgend mit Bezug zu den Figuren der Zeichnung näher erläutert. Es zeigen:

A preferred embodiment of the invention is shown schematically in the drawing and is explained in more detail below with reference to the figures of the drawing. Show it:
Fig. 1
a perspective view of a corner bearing;
Fig. 2
a top view of the corner bearing with the sash open;
Fig. 3
a sectional view through the corner bearing.

Die Figur 1 zeigt ein Ecklager 10 mit einem Rahmenbefestigungsteil 11, an dem ein als Tragarm ausgebildeter erster Scherenarm 12 an einer ersten Koppelstelle 13 drehbar angeordnet ist. An dem Rahmenbeschlagteil 11 ist weiterhin an einer zweiten Koppelstelle 14 ein als Steuerarm ausgebildeter zweiter Scherenarm 15 drehbar angeordnet. An der Koppelstelle 14 ist ein Exzenter 16 vorgesehen, über den sich die Position des Endes 17 des Scherenarms 15 auf dem Rahmenbeschlagteil 11 einstellen lässt.The Figure 1 shows a corner bearing 10 with a frame fastening part 11, on which a first scissor arm 12 designed as a support arm is rotatably arranged at a first coupling point 13. On the frame fitting part 11, a second scissor arm 15 designed as a control arm is rotatably arranged at a second coupling point 14. At the coupling point 14, an eccentric 16 is provided, via which the position of the end 17 of the scissor arm 15 on the frame fitting part 11 can be adjusted.

An dem ersten Scherenarm 12, der unter dem zweiten Scherenarm 15 angeordnet ist, ist ein Flügelkoppelelement 18 in Form eines Zapfens angeordnet. Gleichfalls ist an dem zweiten Scherenarm 15 ein Flügelkoppelelement 19 in Form eines Zapfens angeordnet. Ein nicht dargestelltes Flügelbeschlagteil kann am Flügel montiert und auf die Flügelkoppelelemente 18, 19 aufgesetzt werden.A wing coupling element 18 in the form of a pin is arranged on the first scissor arm 12, which is arranged below the second scissor arm 15. Likewise, a wing coupling element 19 in the form of a pin is arranged on the second scissor arm 15. A wing fitting part (not shown) can be mounted on the wing and placed on the wing coupling elements 18, 19.

Die Figur 2 zeigt eine Draufsicht auf das Ecklager 10. Hierbei ist das Ecklager 10 mit einem Flügel 25 verbunden, der einen Überschlag 26 aufweist. Bei einer Öffnungsbewegung des Flügels 25 muss verhindert werden, dass der Überschlag 26 mit dem festen Rahmen 27 kollidiert. Am festen Rahmen 27 ist das Rahmenbeschlagteil 11 befestigt. Vom Flügel 25 ist nur der Überschlag 26 dargestellt.The Figure 2 shows a top view of the corner bearing 10. Here, the corner bearing 10 is connected to a wing 25 which has a flap 26. In the event of an opening movement of the sash 25, the rollover 26 must be prevented from colliding with the fixed frame 27. The frame fitting part 11 is attached to the fixed frame 27. Only the flap 26 of the wing 25 is shown.

Der Scherenarm 15 weist einen als Führungskontur ausgebildeten Durchbruch 28 auf, in dem ein Steuerteil 29 in Form eines Zapfens des Scherenarms 12 geführt ist. Aufgrund der Kopplung des zweiten Scherenarms 15 und des ersten Scherenarms 12 über den Durchbruch 28 und das Steuerteil 29 wird eine Kinematik realisiert, die dazu führt, dass der Flügel 25 mit seinem Flügelüberschlag 26 zunächst ein Stück weit abgestellt wird, ehe die eigentliche Schwenkbewegung des Flügels 25 in eine Offenstellung erfolgen kann.The scissor arm 15 has an opening 28 designed as a guide contour, in which a control part 29 in the form of a pin of the scissor arm 12 is guided. Due to the coupling of the second scissor arm 15 and the first scissor arm 12 via the opening 28 and the control part 29, a kinematic system is implemented which means that the wing 25 with its wing overlap 26 initially a little is turned off before the actual pivoting movement of the wing 25 can take place in an open position.

In der Figur 2 ist der Durchbruch 28 nur gestrichelt dargestellt, da dieser von oben abgedeckt ist.In the Figure 2 the opening 28 is only shown in dashed lines because it is covered from above.

Insbesondere weist der Scherenarm 15, wie sich der Figur 3 entnehmen lässt, zwei Materiallagen 40, 41 auf. Der Durchbruch 28 ist in der unteren Materiallage 40 realisiert. Die obere Materiallage 41 weist eine Ausnehmung 42 im Bereich des Durchbruchs 28 auf. Die Materiallage 41 ist jedoch durch die Ausnehmung 42 nicht vollständig durchbrochen, so dass der Durchbruch 28 von oben her immer noch durch die obere Materiallage 41 abgedeckt ist. Der Durchbruch 28 stellt, wie bereits erwähnt wurde, eine Führungskontur für das Steuerteil 29 dar. In dem Durchbruch 28 kann Schmiermittel angeordnet sein. Dieses kann sich nicht mit Schmutz vermengen, da der Durchbruch 28 von oben her durch die obere Materiallage 41 abgedeckt ist. Durch die Ausnehmung 42 werden die Reibflächen vergrößert, so dass insgesamt Verschleiß an den zwischen Scherenarm 15 und Steuerelement 29 bzw. Scherenarm 12 wirkenden Reibflächen reduziert wird.In particular, the scissors arm 15, as the Figure 3 can be seen, two material layers 40, 41 on. The opening 28 is realized in the lower material layer 40. The upper material layer 41 has a recess 42 in the area of the opening 28. However, the material layer 41 is not completely broken through by the recess 42, so that the opening 28 is still covered from above by the upper material layer 41. As already mentioned, the opening 28 represents a guide contour for the control part 29. In the opening 28, lubricant can be arranged. This cannot mix with dirt, since the opening 28 is covered from above by the upper material layer 41. The friction surfaces are enlarged by the recess 42, so that overall wear on the friction surfaces acting between the scissor arm 15 and the control element 29 or the scissor arm 12 is reduced.

In der Figur 3 ist weiterhin eine Verbindungsstelle 43 angedeutet, an der die Materiallagen 40, 41 spielfrei miteinander verbunden sind. Sind die Materiallagen 40, 41 beispielsweise aus Stahl ausgebildet, kann die Verbindungsstelle 43 als Schweißpunkt ausgebildet sein.In the Figure 3 a connection point 43 is also indicated at which the material layers 40, 41 are connected to one another without play. If the material layers 40, 41 are formed from steel, for example, the connection point 43 can be formed as a weld point.

Durch die mehrfache Verbindung der Materiallagen 40, 41 über die Länge des Arms 15, insbesondere im Bereich des Flügelkoppelelements 19, der Verbindungsstelle 43 und dem Flügelkoppelelement 18 wird die Steifigkeit des Scherenarms 15 so weit erhöht, dass nur eine geringe Verformung der Gleitflächen in Folge einer Flügellast erfolgt.The multiple connection of the material layers 40, 41 over the length of the arm 15, in particular in the area of the wing coupling element 19, the connection point 43 and the wing coupling element 18, increases the rigidity of the scissor arm 15 increased so much that there is only a slight deformation of the sliding surfaces as a result of a wing load.

Durch die Scherenarme 12, 15 wird ein Scherenlager ausgebildet, wobei an einer Koppelstelle im Bereich des Steuerelements 29 zwischen den Armen 12, 15 eine Gleitzwischenlage 45 vorgesehen ist. Diese kann beispielsweise aus Kunststoff oder Edelstahl ausgebildet sein.A scissor bearing is formed by the scissor arms 12, 15, a sliding liner 45 being provided at a coupling point in the area of the control element 29 between the arms 12, 15. This can for example be made of plastic or stainless steel.

Auch an der Koppelstelle 14 kann zwischen dem Arm 15 und dem Rahmenbefestigungsteil 11 eine Gleitzwischenlage 44 vorgesehen sein.A sliding intermediate layer 44 can also be provided at the coupling point 14 between the arm 15 and the frame fastening part 11.
