Description

Die Erfindung betrifft eine Schließvorrichtung für Flügelfenster oder-türen mit einem am Flügelrahmen umlaufend angeordneten, insbesondere durch einen Griff betätigbaren flexiblen Getriebeband und mit einer Spannvorrichtung für das Getriebeband, sowie mittels des Getriebebandes bewegten Verriegelungselementen.The invention relates to a locking device for casement windows or doors a circumferentially arranged on the casement, in particular by a handle actuable flexible gear belt and with a tensioning device for the Gear belt, as well as moved by means of the gear belt Locking elements.

Derartige Schließvorrichtungen, bei denen als Getriebeband faserverstärkte Kunststoffbänder verwendet werden, sind z.B. aus der DE 33 31 827 bekannt. Aus dieser Schrift ist es bekannt, für Schließvorrichtungen von Flügelfenstern oder -türen Getriebebänder mit offenen Enden zu verwenden, die mittels einer speziellen Vorrichtung miteinander verbunden werden, wobei gleichzeitig mit der Verbindungsvorrichtung das um den Rahmen herumliegende Getriebeband gespannt wird.Such locking devices, in which fiber-reinforced as a gear belt Plastic straps are used, e.g. known from DE 33 31 827. Out this document it is known for closing devices of casement windows or doors to use gear belts with open ends, which by means of a special device can be connected to each other, while simultaneously with the Connecting device the gear band lying around the frame is excited.

Da die Verbindungs- und Spannvorrichtung fest mit dem Getriebeband verbunden ist, wird bei einer Bewegung des Getriebebandes, z.B. beim Öffnen oder Schließen des Fensters, automatisch auch diese Vorrichtung innerhalb des Flügelrahmens mitbewegt. Dementsprechend werden speziell geformte Flügelrahmen benötigt, die an der Position der Spann- und Verbindungsvorrichtung eine entsprechend große Ausnehmung im Rahmen aufweisen.Because the connection and tensioning device is firmly connected to the gear belt is, with a movement of the gear belt, e.g. when opening or closing of the window, this device automatically within the casement moved. Accordingly, specially shaped casement frames are needed, which a correspondingly large one at the position of the tensioning and connecting device Have recess in the frame.

Aus der genannten Schrift ist es ebenfalls bekannt, an dem Getriebeband Verrieglungselemente zu befestigen, die beim Schließen des Fensters mit einer entsprechend ausgeformten und am festen Fensterrahmen angebrachten Vorrichtung in Eingriff kommen.It is also known from the cited document on the gear belt To fasten the locking elements when closing the window with a appropriately shaped and attached to the fixed window frame Device engage.

Diese sind zwar feinstufig auf dem Getriebeband versetzbar, müssen jedoch zur Anbringung am Getriebeband um dieses herum gelegt werden, um anschließend mittels einer Rastverbindung auf dem Getriebeband arretiert zu werden. Sofern eine Versetzung des Verriegelungsbeschlagteiles auf dem Getriebeband gewünscht wird, ist es nötig, die Spannung des Getriebebandes zu lösen, so daß das Band mit dem hierauf befestigten Verriegelungsbeschlagteil aus der Führungsnut entnommen werden kann, um das Verriegelungsbeschlagteil zu lösen und erneut anzubringen.Although these can be moved in fine stages on the gear belt, they must be used Attachment to the gear belt to be placed around this, afterwards to be locked on the gear belt by means of a locking connection. Provided a displacement of the locking fitting part on the gear belt is desired, it is necessary to release the tension of the gear belt so that the tape with the locking fitting part attached to it from the Guide groove can be removed to release the locking fitting and reattach.

Auch aus der DE 34 24 165 ist es bekannt, für Schließvorrichtungen von Fenster und Türen Getriebebänder zu verwenden, deren Enden mittels einer Spannvorrichtung verbunden werden. Weiterhin ist es aus dieser Schrift bekannt, Verriegelungselemente durch ein Herumlegen um das Band an diesem zu befestigen.From DE 34 24 165 it is known for closing devices of windows and doors gear belts to use, the ends of which by means of a Clamping device can be connected. Furthermore, it is known from this document Locking elements by laying around the tape on it Fasten.

Aus der FR 2 532 979 ist es darüber hinaus bekannt, zur Spannung eines Getriebebandes in Schiffstüren eine Spannvorrichtung innerhalb der Tür ortsfest anzuordnen, wobei weiterhin das Getriebeband zur Realisierung der Spannung zwischen Umlenkelementen um ein Antriebsrad herumgeführt ist. Eine derartige Spannvorrichtung ist auch aus der US 4 844 518 bekannt. Die hier offenbarten Spannvorrichtungen bestehen aus mehreren einzelnen Elementen, die die Handhabung und Montage der Spannvorrichtung aufwendig machen.From FR 2 532 979 it is also known to tension a Gear belt in ship doors a fixture inside the door stationary to arrange, while still the gear belt to realize the tension is guided around a drive wheel between deflection elements. Such Tensioning device is also known from US 4,844,518. The ones disclosed here Clamping devices consist of several individual elements that make up the Make handling and assembly of the clamping device complex.

Aufgabe der Erfindung ist es, eine einfach handzuhabende Schließvorrichtung zu schaffen, bei der ein Getriebeband auf einfache Art und Weise, ohne separate mitbewegte Vorrichtungen, im Flügelrahmen gespannt werden kann. The object of the invention is to provide an easy-to-use locking device create a gear belt in a simple way without separate moving devices can be tensioned in the casement.

Es ist weiterhin Aufgabe der Erfindung, Verriegelungsbeschlagteile zu schaffen, die auch nachträglich am fertig verspannten Getriebeband und an beliebiger Position im Flügelrahmen befestigt werden können und bei denen lediglich ein Verriegelungselement des Beschlages bei entsprechender Bewegung vom Getriebeband mitgeführt wird.It is a further object of the invention to provide locking fitting parts which can also be retrofitted on the fully tensioned gear belt and on any Position in the casement can be fixed and only one Locking element of the fitting with appropriate movement from Gear belt is carried.

Diese Aufgabe wird dadurch gelöst, daß die erfindungsgemäße Schließvorrichtung ein Getriebeband aufweist, das mittels einer am Flügelrahmen ortsfest angeordneten Spannvorrichtung spannbar ist, die eine Einheit bildet aus zwei Montageplatten, zwischen denen zwei Umlenkelemente und ein zwischen den Umlenkelementen mittels einer lösbaren Rastverbindung positionierbares Antriebsrad angeordnet sind, wobei das Getriebeband zwischen den Umlenkelementen um das Antriebsrad herumgeführt ist.This object is achieved in that the locking device according to the invention has a gear belt, which is stationary by means of a sash frame Arranged tensioning device can be tensioned, which forms a unit from two Mounting plates, between which two deflection elements and one between the Deflection elements can be positioned by means of a releasable latching connection Drive wheel are arranged, the gear belt between the Deflection elements is guided around the drive wheel.

Hierbei ist es besonders vorteilhaft, wenn das eingesetzte Getriebeband endlos ist.It is particularly advantageous here if the gear belt used is endless.

Durch die Verwendung eines endlosen Getriebebandes im Gegensatz zu einem Getriebeband mit offenen Enden, kann ein einfacher Flügelrahmen konstruiert werden, der keinerlei Aussparungen für eventuell mitbewegte Verbindungselemente aufweisen muß. Bei der erfindungsgemäßen Schließvorrichtung kann das endlose Getriebeband, welches notwendigerweise ein geringfügig größeren Umfang aufweist als der Flügelrahmen, in seiner Gänze in den Rahmen eingelegt und in die ortsfest angeordnete Spannvorrichtung eingefädelt werden.By using an endless gear belt as opposed to one Gear belt with open ends, a simple casement can be constructed be who has no recesses for any moving Must have fasteners. In the case of the invention Locking device can be the endless gear belt, which is necessarily a has a slightly larger circumference than the casement, in its entirety in inserted the frame and into the stationary clamping device be threaded.

Da Getriebebänder häufig kommerziell nicht in der endlosen, sondern nur in der Form mit zwei offenen Enden erhältlich sind, kann ein endloses Getriebeband auch durch die Verbindung der beiden offenen Enden miteinander gebildet werden. Diese Verbindung kann z.B. mittels eines einfachen Verbindungselementes erfolgen, welches außer der reinen Verbindungsfunktion keine weitere Funktion, insbesondere keine Spannfunktion übernimmt und daher so klein ausgeführt werden kann, daß im Rahmen keine Aussparung hierfür vorgesehen werden muß. Because gear belts are often not commercially available in the endless, but only in the Form with two open ends are available, an endless gear belt can too by connecting the two open ends together. This connection can e.g. by means of a simple connecting element which, apart from the pure connection function, has no other function, in particular does not take over a clamping function and is therefore made so small can be that no recess must be provided for this in the frame.

Bei Verwendung eines Getriebebandes mit Verzahnung kann ein derartiger einfacher Verbinder z.B. aus einem länglichen U-Profil bestehen, das auf der Innenseite eines der U-Schenkel eine dem Getriebeband entsprechende Verzahnung aufweist. In diese Verzahnung können von der offenen Seite des U-Profils die beiden Enden des Getriebebandes eingelegt werden, so daß die Verzahnungen von Band und Profil ineinandergreifen und die Rückseite des Bandes an der zahnlosen Innenseite des gegenüberleigenden U-Schenkels anliegt.When using a gear belt with teeth, such a simple connector e.g. consist of an elongated U-profile, which on the Inside of one of the U-legs a corresponding to the gear belt Has teeth. This toothing can be seen from the open side of the U-profile the two ends of the gear belt are inserted so that the Interlocking teeth of the band and profile and the back of the Band on the toothless inside of the opposite U-leg is applied.

Die Länge des U-profilförmigen Verbindungselementes orientiert sich hierbei an den maximal aufzunehmenden Zugkräften im Band, so daß bei einer hohen zu erwartenden Belastung in einem längeren Verbinder mehrere Zähne der offenen Enden des Getriebebandes mit der Verzahnung des Verbinders ineinandergreifen. Ein auf diese einfache und platzsparende Weise gebildetes Getriebeband aus einen Band mit zwei offenen Enden wird als endloses Getriebeband im Sinne der Erfindung verstanden. Selbstverständlich können auch andere einfache Verbindungskonstruktionen gewählt werden.The length of the U-shaped connecting element is based on this the maximum tensile forces to be absorbed in the band, so that at a high expected load in a longer connector multiple teeth of the open Interlock the ends of the gear belt with the teeth of the connector. A gear belt formed in this simple and space-saving manner a belt with two open ends is called an endless gear belt in the sense of Invention understood. Of course, other simple ones can Connection structures can be selected.

Die ortsfest und bevorzugt in der Nähe des Betätigungshebels (Olive) angeordnete Spannvorrichtung wirkt derart auf das endlose Getriebeband, daß der effektive Umfang des Flügelrahmens relativ zum Umfang des Getriebebandes durch eine Verschiebung von Elementen, insbesondere von Umlenkelementen und/oder einem Antriebsrad zueinander vergrößert wird. Hierdurch wird eine Verspannung des Getriebebandes im Flügelrahmen erreicht.The stationary and preferably arranged in the vicinity of the operating lever (olive) Clamping device acts on the endless gear belt in such a way that the effective one Perimeter of the casement relative to the circumference of the gear belt by a Displacement of elements, in particular of deflection elements and / or a drive wheel is enlarged to each other. This causes tension of the gear belt in the casement.

Die Schließvorrichtung ist gemäß der Erfindung derart konstruiert, daß das Getriebeband zwischen zwei Umlenkelementen um ein Rad herumgeführt ist. Hierbei können sowohl die Umlenkelemente als auch das Antriebsrad verschiebbar ausgebildet sein. Das Antriebsrad kann gleichzeitig mit einem Griff oder der Welle einer Antriebsvorrichtung, z.B. eines Motors verbunden und über diese(n) angetrieben sein. The locking device is constructed according to the invention such that the Gear belt between two deflection elements is guided around a wheel. Here, both the deflection elements and the drive wheel can be moved be trained. The drive wheel can simultaneously with a handle or the shaft a drive device, e.g. connected to an engine and via this be driven.

Durch diese Art der Führung des Getriebebandes wird bei einer Verspannung erreicht, daß das Band zusätzlich durch eine resultierende Kraft gegen das Rad gedrückt wird. Um für den Antrieb eine formschlüssige und daher rutschfeste Verbindung zu schaffen, ist es vorteilhaft, wenn Rad und Getriebeband eine ineinandergreifende Verzahnung aufweisen.With this type of guidance of the gear belt, there is tension achieved that the tape additionally by a resulting force against the wheel is pressed. To ensure a positive and therefore non-slip for the drive To create a connection, it is advantageous if the wheel and the gear belt have interlocking teeth.

Da aufgrund der Umlenkung des gespannten Getriebebandes mit Hilfe der Umlenkelemente eine erhöhte Reibung zwischen Umlenkelement und Getriebeband auftritt, ist es bevorzugt, daß wenigstens ein Umlenkelement drehbar ausgeführt ist. Insbesondere kann es sich bei den Umlenkelementen um eine Rolle oder auch um Räder handeln, die in ihrer Breite an die Breite des Getriebebandes angepaßt sind.Because of the deflection of the tensioned gear belt with the help of Deflection elements increased friction between the deflection element and Gear belt occurs, it is preferred that at least one deflecting element is rotatable is executed. In particular, the deflection elements can be a role or also act as wheels, the width of which corresponds to the width of the gear belt are adjusted.

Umlenkelemente und Antriebsrad sind zur Bildung einer vormontierbaren Einheit zwischen zwei Montageplatten angeordnet, wie dies bei der sogenannten Olive eines Fensters üblich ist.Deflection elements and drive wheel form a preassembled unit arranged between two mounting plates, as is the case with the so-called olive a window is common.

Aufgrund der Konstruktion ist es somit ebenfalls möglich, die Elemente, die zur Befestigung des Handgriffes am Flügelrahmen vorgesehen sind, auch als Umlenkelemente zu verwenden.Due to the construction, it is also possible to use the elements used for Attachment of the handle on the casement are provided, also as To use deflection elements.

Bei der erfindungsgemäßen Schließvorrichtung wird die als Einheit fertigbare Spannvorrichtung durch die zwei genannten Montageplatten gebildet, die z.B. durch zwei Umlenkelemente oder extra vorgesehene Verbindungselemente parallel auf Abstand gehalten sind.In the locking device according to the invention, the one that can be manufactured as a unit Clamping device formed by the two mentioned mounting plates, which e.g. through two deflection elements or specially provided connecting elements are kept parallel at a distance.

Mittels einer Rastverbindung (Schnappverbindung) wird zwischen den Umlenkelementen ein Antriebsrad angeordnet, so daß ein lose über die Verbindungselemente liegendes Getriebeband dadurch spannbar bzw. zumindest vorspannbar ist, daß das Antriebsrad zwischen die beiden Umlenkelemente gedrückt wird und in dieser Position z.B. aufgrund der Rastverbindung verbleibt. By means of a snap connection (snap connection) becomes a drive wheel between the deflection elements arranged so that a loose over the connecting elements Gear belt can be tensioned or at least pretensioned in that the Drive wheel is pressed between the two deflection elements and in this Position e.g. remains due to the locking connection.

Um eine Rastverbindung zu realisieren, ist es vorteilhaft, in einer der Montageplatten eine Bohrung vorzusehen, in die ein an dem Antriebsrad vorgesehener koaxialer Vorsprung einsetzbar bzw. einrastbar ist.To implement a locking connection, it is advantageous to use one of the Mounting plates to provide a hole in the one on the drive wheel provided coaxial projection can be used or snapped.

Da die Breite des Antriebsrades inklusive Vorsprung kleiner ist als der Abstand der Montageplatten, um eine Verschiebung des Antriebsrades zwischen den Platten und den Umlenkelemente zu ermöglichen, ist vorteilhafter Weise auf der dem Vorsprung gegenüberliegenden Seite des Antriebsrades eine Ausnehmung ausgebildet, in die eine Druckfeder einsetzbar ist.Since the width of the drive wheel including the projection is smaller than the distance between the Mounting plates to shift the drive wheel between the plates and to enable the deflection elements is advantageous on the Projection opposite side of the drive wheel has a recess trained, in which a compression spring can be used.

Beim Einschieben des Antriebsrades zwischen die Motageplatten preßt die Druckfeder das Rad mit dem koaxialen Vorsprung gegen die mit der Bohrung versehene Montageplatte, so daß nach dem Einrasten des koaxialen Vorsprunges in der Bohrung eine gesicherte aber wieder lösbare Dreh-Verbindung zwischen Rand und Platte entsteht.When pushing the drive wheel between the motor plates presses Compression spring the wheel with the coaxial projection against the one with the bore provided mounting plate so that after the snap-in of the coaxial projection a secure but releasable rotary connection in the bore between Edge and plate are created.

Für den Fall, daß nach dem Einrasten des Antriebsrades die Spannung des Getriebsbandes nicht ausreichend ist, ist es bevorzugt vorgesehen, wenigstens eines der Umlenkelemente als drehbaren Exzenter auszubilden, um so den effektiven Umfang des Flügelrahmens durch Verdrehen des Umlenkelementes zu vergrößern und so eine weitere Verspannung zu bewirken. Damit die Spannung nach Verdrehen des exzentrischen Umlenkelementes erhalten bleibt, ist dieses arretierbar, z.B. durch Verklemmung, ausgeführt.In the event that the tension of the Gear belt is not sufficient, it is preferably provided, at least to form one of the deflection elements as a rotatable eccentric so as to effective scope of the casement by turning the deflecting element enlarge and thus cause a further tension. So the tension is retained after turning the eccentric deflection element, this is lockable, e.g. by jamming.

In einer Alternative kann das Antriebsrad an einem Hebel angeordnet sein, der einseitig an den Montageplatten oder z.B. an einem der Umlenkelemente angelenkt ist. Das andere Ende das Hebels ist z.B. mit einem Vorsprung versehen, der in eine entsprechende Ausnehmung an einer der Montageplatten oder an einer hierfür vorgesehenen Vorrichtung einrasten kann.In an alternative, the drive wheel can be arranged on a lever that one-sided on the mounting plates or e.g. on one of the deflection elements is articulated. The other end of the lever is e.g. with a projection, the in a corresponding recess on one of the mounting plates or on one provided device can snap into place.

Durch Verschwenkung des Hebels wird das Antriebsrad gegen das Getriebeband und mit diesem zwischen die Umlenkelemente gedrückt, wodurch das Getriebeband gespannt wird. Am Ende des Schwenkbereiches rastet der Vorsprung des Hebels in die vorgesehene Ausnehmung ein, so daß wiederum eine gesicherte aber lösbare Rastverbindung entsteht.By pivoting the lever, the drive wheel is against the gear belt and pressed with this between the deflecting elements, whereby the Gear belt is tensioned. At the end of the swivel range, the A projection of the lever into the recess provided, so that in turn secure but detachable snap connection is created.

Wie erwähnt, kann auch hier ein Exzenter zur weiteren Spannung des Getriebebandes vorgesehen sein.As mentioned, an eccentric can be used to further tension the Gear belt may be provided.

In einer Ausführungsvariante ist, um eine Verspannung des lose in den Flügelrahmen eingelegten Getriebebandes zu erreichen, wenigstens ein Umlenkelement, im wesentlichen parallel, zur Flügelkante verschiebbar. Bei einer Verschiebung des einen Umlenkelementes auf das andere Umlenkelement zu, wirkt durch die Umlenkung sowohl eine Kraft parallel zu dem Flügelrahmen, durch die das Getriebeband gespannt wird, als auch eine weitere Kraft, die das Getriebeband auf dem Rad andrückt und somit eine sichere Verbindung gewährleistet.In one embodiment variant, in order to brace the loose in the To achieve sash inserted gear belt, at least one Deflecting element, essentially parallel to the wing edge. At a Displacement of one deflecting element towards the other deflecting element, acts through the deflection both a force parallel to the casement which the transmission belt is tensioned as well as another force that the Gear belt presses on the wheel and thus a secure connection guaranteed.

Ein Durchrutschen zwischen Rad und Getriebeband ist demnach, insbesondere bei der bevorzugt vorgesehenen Verzahnung ausgeschlossen, was besonders wichtig ist, wenn das Rad mit einem Griff verbunden ist, um als Antriebsrad zu dienen.Slipping between the wheel and the gear belt is accordingly, in particular excluded in the preferred intended gearing, which is special It is important if the wheel is connected to a handle to act as a drive wheel serve.

Um eine präzise Verschiebung des verschiebbaren Umlenkelementes zu gewährleisten, wird dieses Umlenkelement in wenigstens einem Langloch geführt. Da das Umlenkelement in seiner Breite ari das Getriebeband angepaßt ist, wird bevorzugt das Umlenkelement zu beiden Seiten in einem Langloch geführt. Die Langlöcher können hierbei in den Montageplatten vorgesehen sein. Üblicherweise handelt sich bei diesem Umlenkelement um eine Rolle, deren Breite deutlich größer ist als der Durchmesser.To ensure a precise displacement of the displaceable deflection element ensure, this deflection element is guided in at least one slot. Since the width of the deflection element ari is adapted to the gear belt preferably the deflection element is guided on both sides in an elongated hole. The Elongated holes can be provided in the mounting plates. Usually this deflection element is a roller, the width of which is clear is larger than the diameter.

Um eine sichere Verschiebung zu gewährleisten, ist das verschiebbare Umlenkelement vorteilhafterweise in den Schenkeln eines U-förmigen Halteprofils insbesondere drehbar gelagert. Hier wird ebenfalls wieder durch die drehbare Lagerung der Verschleiß zwischen Umlenkelement und Getriebeband verringert. Darüber hinaus garantiert die bezüglich des Getriebebandes beidseitige Lagerung des Umlenkelementes in dem U-förmigen Halteprofil, daß bei Spannung des Riemens, also der Ausübung einer Kraft auf dieses Umlenkelement ein Verkanten derselben verhindert wird.In order to ensure a safe movement, it is movable Deflection element advantageously in the legs of a U-shaped holding profile in particular rotatably mounted. Here is also rotatable again Storage of wear between the deflection element and gear belt reduced. In addition, the two-sided bearing guarantees with regard to the gear belt of the deflecting element in the U-shaped holding profile that when the Belt, ie exerting a force on this deflection element tilting the same is prevented.

Durch die U-Form des Halteprofils ist hierbei gewährleistet, daß das Getriebeband um das Umlenkelement herum, zwischen den Schenkeln des Halteprofils, geführt ist.The U-shape of the holding profile ensures that the gear belt around the deflecting element, between the legs of the holding profile is.

Dementsprechend ist durch die gewählte Konstruktion die Möglichkeit gegeben, insbesondere in dem Bereich des Betätigungsgriffes den im Flügelrahmen parallelen Verlauf des Getriebeband mittels des verschiebbaren Umlenkelementes durch das U-förmige Halteprofil hindurch in eine Richtung umzulenken, in der sich der Abstand des Getriebebandes zur Flügelrahmenkante vergrößert.Accordingly, the chosen construction gives the possibility especially in the area of the operating handle in the casement parallel course of the gear belt by means of the displaceable deflection element to redirect through the U-shaped holding profile in a direction in which the distance between the gear belt and the edge of the casement is increased.

Nach dieser Änderung des Getriebebandverlaufes wird das Getriebeband um das z.B. über den Griff angetriebene Rad derart herumgelenkt, daß der Verlauf wiederum auf die Flügelkante hin gerichtet ist. Durch das weitere Umlenkelement wird der Verlauf des Getriebebandes wiederum parallel zur Flügelrahmenkante ausgerichtet. Dieser Verlauf des Getriebebandes kann z.B. realisiert werden, wenn die Drehachse des Antriebsrades von der Flügelrahmenkante einen größeren Abstand aufweist als beide Umlenkelemente.After this change in the course of the gear belt, the gear belt is changed by e.g. Wheel driven over the handle so that the course is again directed towards the wing edge. Through the further deflecting element the course of the gear belt is again parallel to the edge of the casement aligned. This course of the gear belt can e.g. be realized if the axis of rotation of the drive wheel from the sash edge a larger one Has a distance as both deflection elements.

Um eine Verspannung des Getriebebandes durchzuführen, ist am Halteprofil ein Zugelement befestigt. Bei diesem Zugelement kann es sich insbesondere um ein Zahnband oder auch um eine Zahnstange handeln. Auch andere Elemente können hier verwendet werden.In order to brace the gear belt, a is on the holding profile Traction element attached. This tension element can in particular be a Toothed belt or a rack. Other elements can also be used here.

Die Verspannung des Getriebebandes wird nun dadurch erreicht, daß in Richtung parallel zur Flügelrahmenkante mittels des Zugelementes auf das verschiebbare Umlenkelement eine Zugkraft ausgeübt wird, die das verschiebbare Umlenkelement innerhalb des Langloches verschiebt. Um die Zugkraft konstant aufrecht zu erhalten, ist es vorteilhaft, wenn das Zugelement in einem Schloßmechanismus einliegt, der am Flügelrahmen und/oder an den Montageplatten, die im Flügelrahmen angeordnet werden, befestigt ist. The tensioning of the gear belt is now achieved in that in the direction parallel to the sash edge by means of the pulling element on the slidable Deflection element is exerted a tensile force that the displaceable Deflection element moves within the slot. To keep the pulling force constant to maintain, it is advantageous if the tension element in one Lock mechanism rests on the sash and / or on the Mounting plates, which are arranged in the casement, is attached.

Hierbei ist der Schloßmechanismus derart ausgewählt, daß eine Bewegung des Zugelementes in eine Richtung zugelassen und in die entgegengesetzte Richtung durch Arretierung verhindert ist.Here, the lock mechanism is selected such that a movement of the Traction element allowed in one direction and in the opposite direction is prevented by locking.

Da durch den gespannten Riemen auf das Zugelement und somit auf den Mechanismus des Schlosses eine Kraft ausgeübt wird, die der Einschubrichtung des Zugelementes in das Schloß entgegengerichtet ist, erfolgt eine automatische Arretierung des Zugelementes im Schloß. Hierdurch ist gewährleistet, daß die Spannung des Getriebebandes dauerhaft aufrechterhalten bleibt. Sollte sich das Getriebeband aufgrund der dauerhaften Beanspruchung in der Länge dehnen, so ist mit dieser Konstruktion ein einfaches Nachspannen des Getriebebandes möglich, ohne das Getriebeband aus dem Spannmechanismus zu entnehmen.Because of the tensioned belt on the tension element and thus on the Mechanism of the lock a force is exerted which is the direction of insertion of the tension element in the lock is opposite, there is an automatic Locking the tension element in the lock. This ensures that the Tension of the gear belt is maintained permanently. Should that be Stretch the transmission belt in length due to the permanent stress, see above is a simple re-tensioning of the gear belt with this construction possible without removing the gear belt from the tensioning mechanism.

Die erfindungsgemäße Schließvorrichtung, die am oder im Flügelrahmen insbesondere durch Klemmwirkung, ortsfest befestigte Verriegelungsbeschlagteile mit bewegbaren mit dem Getriebeband in Eingriff stehenden Verriegelungselementen aufweist, ist weiterhin dadurch gekennzeichnet, daß das Verriegelungsbeschlagteil mittels U-profilförmiger Verbinder, die das Beschlagteil übergreifen, im Flügelrahmen befestigbar ist.The locking device according to the invention, on or in the casement in particular by means of clamping action, fixed locking fitting parts with movable locking elements which are in engagement with the gear belt has, is further characterized in that the Locking fitting part by means of a U-shaped connector, which Reach over the fitting part, can be fastened in the casement.

Insbesondere durch die Klemmwirkung können die Verriegelungsbeschlagteile an beliebiger Position im Flügelrahmen befestigt werden. Durch das Einsetzen der Verriegelungsbeschlagteile in den Rahmen kommen dabei automatisch die Verriegelungselemente mit dem unterhalb des Beschlags liegenden Getriebeband in Eingriff, ohne daß diese Verriegelungselemente in aufwendiger Weise am Getriebeband befestigt oder herumgelegt werden müssen.The locking fitting parts can, in particular, by the clamping action can be fixed in any position in the casement. By inserting the Locking fittings in the frame come automatically Locking elements with the gear belt underneath the fitting engaged without these locking elements in a complex manner on Gear belt must be attached or put around.

Da das Verriegelungsbeschlagteil durch Verklemmung ortfest im Flügelrahmen befestigt wird, ist es von Vorteil, wenn das Verriegelungsbeschlagteile ein Langloch aufweist, in dem das Verriegelungselement verschieblich einliegt.Since the locking fitting part is fixed in place in the casement by jamming is attached, it is advantageous if the locking hardware parts Has elongated hole in which the locking element is slidably inserted.

Bei der erfindungsgemäßen Ausführung ist das Verriegelungsbeschlagteil mittels U-profilförmiger Rastverbinder im Flügelrahmen befestigt. Diese Rastverbinder übergreifen mit ihren Schenkeln das Verriegelungsbeschlagteil und rasten mit an den Außenseiten der Schenkel vorgesehenen Vorsprüngen in einen in der Nut des Flügelrahmens vorgesehenen Hinterschnitt ein, so daß das Beschlagteil klemmend und ortsfest befestigt wird. Lediglich das Verriegelungselement im Beschlagteil ist beweglich.In the embodiment according to the invention, the locking fitting part is by means of U-shaped snap connector fastened in the casement. These snap connectors overlap the locking fitting part with their legs and engage with them the outsides of the legs provided projections in a in the groove of the Sash provided undercut, so that the fitting part is jammed and is fixed in place. Only the locking element is in the fitting part movable.

Um durch die übergreifenden Verbinder die Breite der Verriegelungsbeschlagteile nicht zu erhöhen, kann dieses an den Übergriffspositionen entsprechende Aussparungen aufweisen.To the width of the locking fitting parts by the overlapping connectors not to increase, this can correspond to the overlapping positions Have recesses.

Um einen anderen möglichst einfachen Klemmechanismus zu realisieren, ist das Verriegelungsbeschlagteil längs des Langloches in zwei Hälften geteilt. Die klemmende Befestigung innerhalb des Rahmens wird dann dadurch erreicht, daß die beiden Beschlagteilhälften nach Einlegen in eine Nut des Flügelrahmens insbesondere mittels Senkkopfschrauben auseinanderdrückbar sind. Durch das Auseinanderdrücken vergrößert sich entsprechend die Breite des Verriegelungsbeschlagteiles, so daß sich dieses zwischen den beiden Wänden der Nut im Flügelrahmen festklemmt.In order to implement another simple clamping mechanism, that is Locking fitting part divided into two halves along the elongated hole. The clamping attachment within the frame is then achieved in that the two fitting part halves after insertion in a groove in the casement can be pushed apart in particular by means of countersunk screws. By the Pushing them apart increases the width of the Locking fitting part, so that this is between the two walls of the Groove clamped in the casement.

Das Auseinanderdrücken der Bechlagteilhälften wird einfacherweise dadurch ermöglicht, daß das Verriegelungsbeschlagteil jeweils an seinen beiden Enden Bohrungen für Senkkopfschrauben aufweist, durch die hindurch eine Senkkopfschraube in ein unter dem Verriegelungsbeschlagteil liegendes Gewindeplättchen eingeschraubt wird.This simply pushes the hardware halves apart allows the locking fitting part at both ends Has holes for countersunk screws through which a Countersunk screw in a one located under the locking fitting part Threaded plate is screwed in.

Aufgrund der Ansenkung der entsprechenden Bohrungen im Verriegelungsbeschlagteil werden die beiden Beschlagteilhälften beim Eindrehen einer Senkkopfschraube auseinandergedrückt.Due to the countersinking of the corresponding holes in the Locking fitting part become the two fitting part halves when screwing in with a countersunk screw.

Da ein Verriegelungsbeschlagteil bei allen möglichen Alternativen im Flügelrahmen über dem Getriebeband eingesetzt wird, ist es erforderlich, daß das im Langloch einliegende Verriegelungselement ein Schließelement und ein mit dem Getriebeband in Eingriff stehendes Antriebsteil aufweist, die beide miteinander über einen Steg verbunden sind, der im Langloch einliegt. Da Schließelement und Antriebsteil des Verriegelungselementes einen deutlich größeren Querschnitt aufweisen, als die Breite des Langloches, ist es nötig, daß der diese beiden Teile verbindende Steg, einen reduzierten Querschnitt aufweist, um weiterhin im Langloch verschieblich zu sein.As a locking fitting part with all possible alternatives in the casement is used over the gear belt, it is necessary that in the slot inserted locking element a closing element and one with the Gear belt engaging drive member, both of them together are connected by a web that lies in the slot. Because closing element and Drive part of the locking element has a significantly larger cross section than the width of the elongated hole, it is necessary that the two parts connecting web, has a reduced cross section to continue in Elongated hole to be movable.

Das Schließelement weist üblicherweise eine Zapfenform auf. Der Querschnitt ist dabei zumeist rund, oval oder eckig. Auch andere Formen und Querschnitte sind je nach Anwendung hier möglich.The closing element usually has a pin shape. The cross section is mostly round, oval or angular. Other shapes and cross sections are also possible possible after application.

Um eine feste Verbindung zwischen dem Antriebsteil des Verriegelungselementes und dem Getriebeband zu realisieren, ist es von Vorteil, wenn das Antriebsteil eine dem Getriebeband entsprechende Verzahnung aufweist.To ensure a firm connection between the drive part of the locking element and to realize the gear belt, it is advantageous if the drive part has corresponding toothing the gear belt.

Entsprechend der Erfindung reicht es aus, wenn das Verriegelungsbeschlagteil über dem Getriebeband im Flügelrahmen klemmend befestigt wird. Wenn das Verriegelungsbeschlagteil tief genug im Rahmen montiert wird, ist gewährleistet, daß das Antiebsteil des Verriegelungsbeschlagteiles automatisch mit der Verzahnung des Getriebebandes in Eingriff kommt.According to the invention, it is sufficient if the locking fitting part is clamped over the gear belt in the casement. If that Locking fitting part is mounted deep enough in the frame, it is guaranteed that the drive part of the locking fitting part automatically with the Toothing of the gear belt comes into engagement.

Eine umschließende Verbindung zwischen Verriegelungselement und Getriebeband ist dementspechend nicht nötig. Dies bedeutet gleichzeitig, daß jederzeit, also auch im gespannten Zustand des Getriebebandes die Verriegelungsbeschläge aus dem Flügelrahmen entfernt und z.B. an einer anderen Stelle neu montiert werden können.An enclosing connection between the locking element and Accordingly, the gear belt is not necessary. This also means that at any time, including the tensioned state of the gear belt Locking fittings removed from the casement and e.g. on another Site can be reassembled.

Die Figur 1 zeigt eine im Bereich des Betätigungshebels ortsfest angeordnete erfindungsgemäße Spannvorrichtung 2, durch die ein endloses Getriebeband 1 derart hindurchgeführt ist, daß eine einfache Spannung des Bandes ermöglicht wird.FIG. 1 shows a stationary one in the area of the actuating lever tensioning device 2 according to the invention, through which an endless gear belt 1st is passed in such a way that a simple tensioning of the band enables becomes.

Hierzu ist das Getriebeband 1 zwischen zwei Umlenkelementen 4 und 5 um ein Rad 6 herumgeführt, das durch einen nicht dargestellten Hebel, der z.B. durch das Vierkantloch 21 mit dem Rad verbunden ist, betätigt wird.For this purpose, the gear belt 1 is between two deflection elements 4 and 5 Guided wheel 6, which by a lever, not shown, which e.g. by the Square hole 21 is connected to the wheel is operated.

Getriebeband 1, Antriebsrad 6 und die Umlenkelemente 4 und 5, sowie die weiteren später beschriebenen Mechanismen sind dabei zwischen zwei Montageplatten M angeordnet, die durch zusätzliche Elemente oder durch die Umlenkelemente 4,5,20 miteinander verbunden und auf parallelem Abstand gehalten werden. Hierdurch ergibt sich gleichzeitig eine Zwangsführung des Getriebebandes 1, so daß dies nicht vom Antriebsrad oder den Umlenkelementen abrutschen kann. Gear belt 1, drive wheel 6 and the deflection elements 4 and 5, and the other mechanisms described later are between two Mounting plates M arranged by additional elements or by the Deflection elements 4,5,20 connected to each other and at a parallel distance being held. This results in a forced operation of the Gear belt 1, so that this is not from the drive wheel or the deflection elements can slip off.

Um eine besonders sichere Verbindung zwischen dem angetriebenen Rad und Getriebeband sicherzustellen, weisen beide eine ineinandergreifende Verzahnung 7 auf. Um, wie eingangs erwähnt, den Verschleiß von Getriebeband und Umlenkelement möglichst gering zu halten, sind im vorliegenden Fall sowohl das Umlenkelement 4 als auch das verschieblich angeordnete Umlenkelement 5 drehbar ausgeführt.To ensure a particularly secure connection between the driven wheel and To ensure gear belt, both have interlocking teeth 7 on. To, as mentioned at the beginning, the wear of the gear belt and To keep the deflection element as low as possible, both are in the present case Deflection element 4 as well as the displaceably arranged deflection element 5 rotatable.

Um ein Spannen des Getriebebandes zu erreichen, wird das Umlenkelement 5 etwa parallel zur Flügelkante 8 verschoben. Die Verschiebung erfolgt hierbei nach unten, in Richtung auf das Umlenkelement 4.In order to achieve tensioning of the gear belt, the deflection element 5 shifted approximately parallel to the wing edge 8. The shift takes place after below, in the direction of the deflection element 4.

Sollte die Verspannung gelöst werden, so rutscht das Umlenkelement 5 nach oben und es ist möglich, daß das endlose Getriebeband auch auf dem Element 20 zur Anlage kommt. Dementsprechend sollte auch dieses Element aus Gründen des Verschleißes drehbar, z.B. in Form einer Rolle, ausgeführt sein.If the tension is released, the deflection element 5 slides upward and it is possible that the endless gear belt also on the element 20 for Facility is coming. Accordingly, this element should also, for reasons of Wear rotatable, e.g. in the form of a roll.

Die Konstruktion ist im vorliegenden Falle besonders einfach, da das unterste Umlenkelement 4, als auch das Element 20, an dem das Getriebeband nur im völlig gelösten Zustand anliegt, gleichzeitig auch die Befestigungselemente für den Betätigungshebel am Rahmen darstellen. Dementsprechend können als Umlenkelemente in einfacher Weise drehbare Hülsen über die Befestigungsschrauben des Betätigungshebels übergesteckt werden.The construction is particularly simple in the present case, since the lowest Deflection element 4, as well as the element 20 on which the gear belt only in completely loosened condition, at the same time the fasteners for the Show operating lever on the frame. Accordingly, as Deflection elements in a simple manner rotatable sleeves over the Fastening screws of the operating lever are pushed over.

In der Figur 1 zeigt sich, daß das verschiebbare Umlenkelement 5 zu beiden Seiten des Getriebebandes 1 in einem Langloch 9 geführt ist. Weiterhin ist das verschiebbare Umlenkelement 5 in den Schenkeln 10 eines U-förmigen Halteprofils 11 drehbar gelagert. Wie bereit eingangs erwähnt, ergibt sich hierdurch eine gleichmäßige Kräfteverteilung.1 shows that the displaceable deflection element 5 to both Sides of the gear belt 1 is guided in an elongated hole 9. Furthermore, that is displaceable deflection element 5 in the legs 10 of a U-shaped Holding profile 11 rotatably mounted. As already mentioned at the beginning, this results from this an even distribution of forces.

Das Getriebeband 1 wird um das Umlenkelement 5 herum zwischen den Schenkeln 10 durch das U-förmige Halteprofil 11 hindurch, über das angetriebene Rad 6 gelenkt und anschließend wiederum um das Umlenkelement 4 herumgeführt. The gear belt 1 is around the deflection element 5 between the Legs 10 through the U-shaped holding profile 11 through the driven Wheel 6 steered and then in turn around the deflecting element 4th led around.

Die Abbildung 1 zeigt, daß am Halteprofil 11 ein Zahnband 12 befestigt ist, das in einem Schloßmechanismus 13 einliegt, der seinerseits mit dem Flügelrahmen oder den Montageplatten fest verbunden ist. Der Schloßmechanismus ist hierbei derart ausgeführt, daß eine Verschiebung des Zahnbandes 12, nur nach unten möglich ist. Eine Verschiebung nach oben wird durch den Schloßmechanismus durch Arretierung verhindert. Die Arretierung erfolgt dadurch, daß ein Sperriegel in die Verzahnung des Ziehbandes eingreift und so ein Zurückziehen des Bandes in das Schloß verhindert.Figure 1 shows that a toothed belt 12 is attached to the holding profile 11, which in a lock mechanism 13 is inserted, which in turn with the sash or the mounting plates is firmly connected. The lock mechanism is here executed that a displacement of the toothed belt 12, only possible downwards is. A shift upwards is carried out by the lock mechanism Locking prevented. The locking takes place in that a locking bolt in the Interlocking of the pulling belt engages and thus pulling the belt back into the Lock prevented.

Eine Spannung des Bandes ist nun in einfacher Weise dadurch möglich, daß z.B. unter Zuhilfenahme einer Zange, das
U-förmige Halteprofil 11 in die Richtung des Schloßes 13 bewegt wird. Hierbei wir automatisch das Zahnband 12 in seiner Rastung durch das Schloß 13 geführt und gegen ein Zurückziehen arretiert. Die Spannung des Getriebebandes 1 ist damit dauerhaft eingestellt.Tensioning the belt is now possible in a simple manner, for example by using pliers
U-shaped holding profile 11 is moved in the direction of the lock 13. Here we automatically guided the toothed belt 12 in its latching through the lock 13 and locked against retraction. The tension of the gear belt 1 is thus permanently set.

Die Figur 2 zeigt eine ortsfeste Spannvorrichtung, die wieder zwischen zwei Montageplatten M realisiert ist, die durch die Umlenkelemente 4 und 5 oder durch weitere Abstandshalter miteinander verbunden sind.FIG. 2 shows a stationary tensioning device, again between two Mounting plates M is realized by the deflection elements 4 and 5 or by further spacers are connected to each other.

Nach dem Einlegen eines endlosen Getriebebandes 1 in den Flügel, z.B. eines Fensterrahmens, in dem die Spannvorrichtung 2 am Ort des Betätigungshebels angeordnet ist, liegt das Getriebeband 1 zunächst locker über den Umlenkelementen 4 und 5.After inserting an endless gear belt 1 in the wing, e.g. one Window frame in which the clamping device 2 at the location of the operating lever is arranged, the gear belt 1 is initially loosely above the Deflection elements 4 and 5.

Durch Einschieben des Antriebsrades 6 in Pfeilrichtung zwischen die beiden Umlenkelemente 4 und 5 wird das Getriebeband 1 ebenfalls zwischen die Umlenkelemente geführt, so daß sich eine Spannung des Getriebebandes 1 ergibt.By pushing the drive wheel 6 in the direction of the arrow between the two Deflection elements 4 and 5, the gear belt 1 is also between the Deflection elements guided so that a tension of the gear belt 1 results.

Um einen Rastmechanismus zu realisieren, weist eine der Montageplatten eine Bohrung 24 auf, in die nach Einschieben des Antriebsrades 6 dessen koaxialer Vorsprung 25 unter dem Druck der in der Ausnehmung 26 einliegenden Feder 27 eingreift. Hierbei sind Vorsprung 25 und Bohrung 24 derart aneinander angepaßt, daß im verbundenen Zustand eine leichte Drehung des Antriebsrades 6 möglich ist.In order to implement a locking mechanism, one of the mounting plates has one Bore 24 in which the coaxial after the drive wheel 6 is inserted Projection 25 under the pressure of the spring 27 lying in the recess 26 intervenes. Here projection 25 and bore 24 are adapted to one another in such a way that in the connected state a slight rotation of the drive wheel 6 is possible is.

Für den Fall, daß das Getriebeband 1 aus dem Rahmen entnommen werden soll, reicht es aus, auf den Vorsprung 25 einen Druck gegen die Kraft der Feder 27 auszuüben und nach dem Ausklinken des Vorsprunges 25 aus der Bohrung 24 das Antriebsrad 6 zwischen den Montageplatten M herauszuziehen.In the event that the gear belt 1 is to be removed from the frame, it suffices to apply pressure to the projection 25 against the force of the spring 27 to exercise and after notching the projection 25 from the bore 24 Pull out the drive wheel 6 between the mounting plates M.

Sollte sich-die Spannung des Getriebebandes 1 nach dem Einrasten des Antriebsrades 6 als nicht ausreichend erweisen, so wird wenigstens eines der Umlenkelemente, im vorliegenden Fall das Umlenkelement 4 als drehbarer und arretierbarer Exzenter ausgebildet. Dies kann entweder dadurch realisiert sein, das das kreisrunde Umlenkelement 4 eine außermittige Drehachse 28 aufweist oder aber eine leichte Eiform hat, wie es gepunktet dargestellt ist. Durch eine Verdrehung dieses Umlenkelementes kann sodann das Getriebeband weiter gespannt werden.Should the tension of the gear belt 1 change after the snap-in Drive wheel 6 prove to be insufficient, at least one of the Deflection elements, in the present case the deflection element 4 as a rotatable and lockable eccentric. This can either be realized by the the circular deflection element 4 has an eccentric axis of rotation 28 or but has a slight egg shape as shown in dotted lines. By a Rotation of this deflection element can then continue the gear belt be excited.

Gegenüber Figur 2 unterscheidet sich die Spannvorrichtung dadurch, daß das Antriebsrad 6 an einem Hebelelement 29 drehbeweglich befestigt ist, welches seinerseits mit seinem einen Ende 29a drehbar am Umlenkelement 5 angelenkt ist.Another embodiment is shown in Figure 3. Opposite figure 2, the clamping device differs in that the drive wheel 6 a lever element 29 is rotatably attached, which in turn with one end 29a is rotatably articulated on the deflection element 5.

Durch ein Verschwenken des Hebelelementes 29 in Pfeilrichtung wird das Antriebsrad 6 zwischen die Umlenkelemente 4 und 5 geführt, wodurch, wie eingangs beschrieben, das Getriebeband gespannt wird.By pivoting the lever element 29 in the direction of the arrow Drive wheel 6 between the deflection elements 4 and 5, whereby how described at the beginning, the gear belt is tensioned.

Die Position des Antriebsrades 6 zwischen den Umlenkelementen 4 und 5 wird dadurch gesichert, daß ein Vorsprung 30, der sich am zweiten Hebelende 29b befindet, nach Verschwenkung des Hebelelementes 29 in die Endlage in eine an der Montageplatte M vorgesehene Ausnehmung 31 einrastet. Die Befestigung des Hebelendes 29b an der Montageplatte M kann auch durch andere Mechanismen als die beschriebene Rastverbindung erreicht werden. The position of the drive wheel 6 between the deflection elements 4 and 5 is secured by a projection 30 which is located at the second lever end 29b is, after pivoting the lever member 29 in the end position in a the mounting plate M provided recess 31 engages. The attachment of the Lever end 29b on the mounting plate M can also by other mechanisms can be achieved as the locking connection described.

Die Figur 4 zeigt ein Verriegelungsbeschlagteil 14, das am oder im nicht dargestellten Flügelrahmen insbesondere durch eine Klemmwirkung, ortsfest befestigbar ist. Weiterhin ist in der Figur 2, das innerhalb des Verriegelungsbeschlagteils 14 bewegbare und mit dem Getriebeband in Eingriff stehende Verriegelungselement 3 zu erkennen. Um eine Verschiebung des Verriegelungselementes 3 innerhalb des Verriegelungsbeschlagteiles 14 zu gewährleisten, weist dieses ein Langloch 15 auf, in dem das Verriegelungselement 3 einliegt.FIG. 4 shows a locking fitting part 14 which is not on or in sash frame shown, in particular by a clamping action, stationary is attachable. Furthermore, in Figure 2, that within the Locking fitting part 14 movable and engaged with the gear belt standing locking element 3 to recognize. To shift the Locking element 3 within the locking fitting part 14 ensure, this has an elongated hole 15 in which the locking element 3 is inserted.

Das Verriegelungselement 3 besteht selbst aus 3 Teilen, nämlich dem Schließelement 16, dem mit dem Getriebeband in Eingriff stehenden Antriebsteil 17, sowie einem querschnittreduzierten Steg 18, über den die beiden erstgenannten Teile verbundenden sind. Der Querschnitt des zapfenförmigen Schließelementes ist hier rund. Auch andere Querschnitte sind möglich.The locking element 3 itself consists of 3 parts, namely the Closing element 16, the drive part engaged with the gear belt 17, and a reduced cross-section web 18, over which the two first mentioned parts are connected. The cross section of the cone-shaped The closing element is round here. Other cross sections are also possible.

Um eine sichere Verbindung zwischen dem Antriebsteil 17 und dem Getriebeband 1 zu gewährleisten, weist das Antriebsteil 17 eine zum Getriebeband passende Verzahnung 19 auf.To ensure a secure connection between the drive part 17 and the gear belt To ensure 1, the drive part 17 has a matching to the gear belt Tooth 19 on.

Eine klemmende Befestigung im Flügelrahmen wird dadurch ermöglicht, daß das Verriegelungsbeschlagteil 14 längs des Langloches 15 entlang der in der Figur 2 dargestellten Trennlinie T, in zwei Hälften 14a und 14b geteilt ist. Entsprechend der dargestellten Konstruktion weist das Verriegelungsbeschlagteil an seinem Ende jeweils auf der Trennlinie T eine Bohrung 22a bzw. 22b auf, die für den Einsatz von Senkkopfschrauben eine Ansenkung aufweisen.A clamping attachment in the casement is made possible by the fact that Locking fitting part 14 along the elongated hole 15 along that in FIG. 2 shown dividing line T, is divided into two halves 14a and 14b. Corresponding the construction shown has the locking fitting on his End each on the dividing line T on a bore 22a and 22b, for the Use countersunk screws have a countersink.

Werden nun nicht dargestellte Senkkopfschrauben durch die Bohrung 22a bzw. 22b hindurch in die unter dem Verriegelungsbeschlagteil liegenden Gewindeplättchen 23a bzw. 23b eingeschraubt, so werden durch den Kopf der Schraube die Beschlagteilhälften 14a und 14b auseinandergedrückt. Durch die hieraus resultierende Verbreiterung des Verriegelungsbeschlagteiles 14 ist eine klemmende Verbindung des Beschlagteiles innerhalb einer Nut des Flügelrahmens möglich. If countersunk screws not shown through the bore 22a or 22b into those lying under the locking fitting part Threaded plate 23a or 23b screwed in, so through the head Screw the fitting part halves 14a and 14b apart. Through the resulting widening of the locking fitting part 14 is a clamping connection of the fitting part within a groove of the casement possible.

Bei der Befestigung des Verriegelungsbeschlagteiles 14 im Rahmen ist lediglich darauf zu achten, daß dieses tief genug in die Nut des Rahmens eingesetzt wird, um zu gewährleisten, daß die Verzahnung 19 des am Verriegelungselement 3 angeordneten Antriebsteiles 17 eine sichere Verbindung mit dem endlosen Getriebeband 1 eingeht.When fastening the locking fitting part 14 in the frame is only make sure that this is inserted deep enough into the groove of the frame, to ensure that the teeth 19 of the locking element 3 arranged drive part 17 a secure connection to the endless Gear belt 1 arrives.

Hier wird deutlich, daß das Verriegelungsbeschlagteil 14 mit seinem Verriegelungselement 3 lediglich von oben auf das Getriebeband 1 aufgesetzt zu werden braucht, um an beliebiger Position einen Verriegelungsbeschlag am Flügelrahmen eines Fensters oder einer Tür anzubringen. Eine aufwendige Konstruktion bei der das Verriegelungsbeschlagteil das Getriebeband umschließt ist mit dieser Konstruktion nicht nötig.Here it is clear that the locking fitting part 14 with his Locking element 3 only placed on the transmission belt 1 from above are needed to lock a locking device at any position To install the casement of a window or door. An expensive one Construction in which the locking fitting part encloses the gear belt is not necessary with this construction.
