Description

Die Erfindung bezieht sich auf eine Drehhandhabe, insbesondere einen Fenstergriff, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a turning handle, in particular a window handle, according to the preamble of claim 1.

Derartige Drehhandhaben besitzen einen Griffhals mit einem oben anschließenden Griff-Hauptteil und einem unteren Ansatz, der in einer meist länglichen Anschlagplatte mit einer zentrischen Buchse drehbar und axialfest angebracht werden kann. Der Griffhals hat üblicherweise ein Vierkantloch zum formschlüssigen Aufnahme eines Betätigungs-Vierkants.Such turning handles have a handle neck with an adjoining handle main part and a lower shoulder, which can be rotatably and axially fixed in a mostly elongated stop plate with a central bushing. The handle neck usually has a square hole for the positive reception of an actuating square.

Die DE-C-1 272 162 beschreibt eine als Fensterolive bezeichnete Drehhandhabe, deren Hals durch einen in eine Nut eingesetzten Sprengring gegen axiales Herausziehen aus der - hier Rosette genannten - Anschlagplatte gesichert ist. Zur axialen Abstützung dient ein gewölbtes Federblech, dessen Auslauf-Enden innen an der Anschlagplatte anliegen. Wie bei älteren Bauformen, beispielsweise entsprechend FR-B-1 315 424 und GB-C-29 022/1913, ist ein an sich einfacher Aufbau mit Unsicherheiten und zum Teil beträchtlichem Aufwand bei der Montage belastet. So kann es größere Zeiten erfordern, bis der Griffhals zuverlässig an bzw. in der Anschlagplatte festgelegt ist, wobei es von Zufälligkeiten abhängen kann, mit welchem Bewegungsspiel dies erfolgt. Wird ein Griffhals-Ansatz an bzw. in einer Lagerbuchse verbördelt, so können die einwirkenden Kräfte zu einseitigen Verklemmungen, aber auch zu loser Festlegung führen, was die Benutzung beeinträchtigt. Die genannten älternen Konstruktionen erlauben es auch nicht, die für neuzeitliche Fenstergetriebe üblichen Griffstellungen zu markieren oder durch Rastung festzulegen.DE-C-1 272 162 describes a turning handle called a window olive, the neck of which is secured by a snap ring inserted into a groove against axial pulling out of the stop plate - referred to here as a rosette. A curved spring plate is used for axial support, the outlet ends of which rest against the inside of the stop plate. As with older designs, for example in accordance with FR-B-1 315 424 and GB-C-29 022/1913, an inherently simple structure is fraught with uncertainties and sometimes considerable effort during assembly. For example, it can take longer times for the handle neck to be reliably fixed on or in the stop plate, and it may depend on randomness with which movement play this takes place. If a handle neck approach is crimped on or in a bearing bush, the acting forces can lead to one-sided jamming, but also to loose fixing, which impairs the use. The older constructions mentioned also do not allow the handle positions that are customary for modern window gears to be marked or fixed by means of latching.

Daher besteht Bedarf an einer Verbesserung. Es ist ein wichtiges Ziel der Erfindung, die Nachteile des Standes der Technik mit wirtschaftlichen Mitteln zu überwinden und eine Drehhandhabe von einfachem Aufbau zu schaffen, die nicht nur mit geringen Kosten herstellbar, sondern vor allem schnell und genau so montierbar ist, daß sie unmittelbar für alte Gebrauchsfunktionen geeignet ist. Insbesondere soll die Handhabe aus nur wenigen, rasch und präzise zusammensetzbaren Teilen bestehen.There is therefore a need for improvement. It is an important object of the invention to overcome the disadvantages of the prior art with economic means and to provide a rotary handle of simple construction which is not only producible at low cost, but above all can be assembled quickly and precisely in such a way that it can be used directly for old usage functions is suitable. In particular, the handle should consist of only a few, quickly and precisely assembled parts.

Ein Grundgedanke der Erfindung ist im kennzeichnenden Teil von Anspruch 1 angegeben. Ausgestaltungen sind Gegenstand der Ansprüche 2 bis 16.A basic idea of the invention is specified in the characterizing part of claim 1. Refinements are the subject of claims 2 to 16.

Erfindungsgemäß ist vorgesehen, daß der Griffhals-Ansatz durch bloßes Einstecken in die Buchse der Anschlagplatte an bzw. in ihr sowohl in Umfangs- als auch in Axialrichtung federnd verrastbar ist. Dies stellt einen bedeutsamen Fortschritt gegenüber herkömmlichen Ausführungsformen dar, bei denen stets zumindest ein zusätzlicher Arbeitsgang zur Festlegung der Handhabenteile benötigt wurde. Daher waren besondere, zum Teil recht komplizierte Befestigungsmittel erforderlich, namentlich für die Verrastung in Umfangs- bzw. Drehrichtung, wofür zahlreiche Konstruktionsvorschläge entwickelt wurden. Die federnde Verrastung nach der Erfindung erlaubt es, mit einfachsten Mitteln eine zuverlässige Montage sicherzustellen, die zugleich die sofortige, einwandfreie Benutzbarkeit der Handhabe gewährleistet.According to the invention it is provided that the handle neck approach can be resiliently locked in the circumferential as well as in the axial direction by simply inserting it into the socket of the stop plate. This represents a significant advance over conventional embodiments, in which at least one additional work step was always required to fix the handle parts. Therefore, special, sometimes quite complicated fasteners were required, especially for locking in the circumferential or rotational direction, for which numerous design proposals were developed. The resilient latching according to the invention makes it possible to ensure reliable assembly using the simplest means, which at the same time ensures the immediate, flawless usability of the handle.

Dazu trägt es bei, wenn nach Anspruch 2 die axiale Verrastung des Griffhals-Ansatzes hart ausgebildet ist, so daß das Einrasten leicht, das Ausrasten jedoch allenfalls mit Werkzeughilfe möglich ist. Solange der Betätigungs-Vierkant eingesetzt ist, kann eine Demontage in keinem Fall erfolgen, wodurch für den Benutzer eine besondere Sicherheit gegeben ist. Gemäß Anspruch 3 kann der Ansatz an seinem angefasten Wulst-Ende achsparallele Schlitze aufweisen. Diese können laut Anspruch 4 in Axialrichtung vor einer Schulter des Griffhalses enden und gemäß Anspruch 5 den Flachseiten seines Vierkantlochs zugeordnet sein. Das geschlitzte Wulst-Ende bildet mithin eine rundum wirksame Schnappfeder, so daß sich zusätzliche Bauelemente erübrigen. Indem die Schlitze nur begrenzte Tiefe haben und sich an den Vierkant-Flachseiten befinden, ist zugleich für minimale Materialschwächung am Griffhals-Ansatz gesorgt.It helps if, according to claim 2, the axial latching of the handle neck extension is hard, so that it snaps in easily, but can only be snapped out with a tool. As long as the actuating square is used, disassembly cannot take place under any circumstances, which gives the user special security. According to claim 3, the approach can have axially parallel slots at its chamfered bead end. According to claim 4, these can end in the axial direction in front of a shoulder of the handle neck and, according to claim 5, can be assigned to the flat sides of its square hole. The slotted bead end thus forms an all-round snap spring, so that additional components are unnecessary. Because the slots are only of limited depth and are located on the square flat sides, there is also minimal material weakening at the handle neck attachment.

Bei einer Handhabe mit einer Anschlagplatte, die an zumindest zwei gegenüberliegenden Seiten Federn mit Rastvorsprüngen hat, sieht die Gestaltung nach Anspruch 6 vor, daß am Umfang des Griffhals-Ansatzes in der Ebene der Rastvorsprünge gegengleiche Rastausnehmungen vorhanden sind, und zwar in solcher Anzahl und Lage, daß die gewünschten Umfangs- bzw. Winkel-Rastpositionen erzielt werden. Das können gemäß Anspruch 7 vier Rastausnehmungen in Winkelabständen von 90° sein, doch sind auch andere Anzahlen und Winkelabstände möglich und erfindungsgemäß vorgesehen. In der Einfachheit der Konsturuktion geht das über frühere Vorschläge hinaus, wie sie beispielsweise im DE-U-8 319 896 enthalten sind.In a handle with a stop plate, which has springs with latching projections on at least two opposite sides, the design according to claim 6 provides that on the periphery of the handle neck approach in the plane of the latching projections there are opposing latching recesses, in such a number and position that the desired circumferential or angular locking positions are achieved. According to claim 7, this can be four locking recesses at angular intervals of 90 °, but other numbers and angular distances are also possible and are provided according to the invention. In the simplicity of the design, this goes beyond previous proposals, such as those contained in DE-U-8 319 896.

Eine wichtige Entwicklung besteht nach dem unabhängigen Anspruch 8 darin, daß der Griffhals-Ansatz sowohl in Umfangs- als auch in Axialrichtung (U bzw. A) durch Einstecken in die Buchse an bzw. in ihr unter Zwischenlage einer an sich bekannten, hier selbstfedernd ausgebildeten Abdeckplatte verrastbar ist, welche um die Achse des Ansatzes bzw. des Griffhalses geschwenkt werden kann, um die Schraublöcher der Anschlag platte freizulegen. Neu ist, daß diese Abdeckplatte selbst ein Federelement darstellt, also keine zusätzliche Feder benötigt, um zwischen Anschlagplatte und Griffhals elastisch abgestützt zu sein. Das ist eine große Vereinfachung im Aufbau der Drehhandhabe, was deren Aussehen ohne Beeinträchtigung der Funktionen wesentlich verbessern kann.An important development according to independent claim 8 is that the handle neck approach in both the circumferential and axial directions (U or A) by plugging into the socket on or in it with the interposition of a known, here designed self-resilient Cover plate can be locked, which can be pivoted about the axis of the neck or the handle neck to expose the screw holes of the stop plate. What is new is that this cover plate itself is a spring element, so it does not require an additional spring to be elastically supported between the stop plate and the handle neck. This is a great simplification in the structure of the turning handle, which can significantly improve its appearance without impairing the functions.

Hierbei ist es günstig, wenn die Abdeckplatte laut Anspruch 9 mit ihrem Rand von der Anschlagplatte elastisch abhebbar ist, also selbst eine Blattfeder darstellt. Gemäß Anspruch 10 ist die Federung der Abdeckplatte im Vergleich zur Verrastung des Griffhals-Ansatzes weich ausgebildet, so daß im Bedarfsfalle auch ein Ausrasten ohne Werkzeughilfe erfolgen kann.It is advantageous if the cover plate can be raised elastically with its edge from the stop plate, that is to say represents a leaf spring itself. According to claim 10, the suspension of the cover plate is soft compared to the locking of the handle neck approach, so that if necessary, it can be disengaged without tooling.

Für die Abstützung der Abdeckplatte ist die Gestaltung von Anspruch 11 vorteilhaft, wonach neben einem zentrischen Durchgangsloch eine Biegefeder vorhanden ist. Diese kann laut Anspruch 12 einstückig mit der Abdeckplatte sein, wobei gemäß Anspruch 13 auch eine Abkantung oder Teilstanzung die Biegefeder bilden kann. Letztere weist nach Anspruch 14 bevorzugt wenigstens zwei nach oben abstehende Bögen, Schenkel o.dgl. auf, die sich an einer Schulter des Griffhalses abstützen und nach Anspruch 15 nahe oder entlang den Längsseiten der Abdeckplatte angeordnet sein können. Diese Konstruktion ist außerordentlich einfach und wirksam, so daß eine zuverlässige Abfederung von großer Lebensdauer gegeben ist, weil eine Ermüdungsgefahr kaum oder nicht besteht.For the support of the cover plate, the design of claim 11 is advantageous, according to which a spiral spring is present in addition to a central through hole. According to claim 12, this can be in one piece with the cover plate, wherein according to claim 13 a bevel or partial stamping can form the spiral spring. The latter preferably has at least two arches, legs or the like which project upwards. on, which are supported on a shoulder of the handle neck and can be arranged according to claim 15 near or along the long sides of the cover plate. This construction is extremely simple and effective, so that there is reliable cushioning with a long service life because there is little or no risk of fatigue.

Wichtig ist ferner das in Anspruch 16 angegebene Merkmal, daß alle Handhabenteile aus einheitlichem Werkstoff bestehen, namentlich aus Kunststoff. Dies unterscheidet die erfindungsgemäße Drehhandhabe grundlegend von dem Stand der Technik. Man erreicht dadurch nicht nur eine besonders einfache und kostengünstige Fertigung, sondern auch ein vorteilhaftes Gestaltungsmittel für Form, Farbe und Oberflächenbeschaffenheit, so daß sich ein gefälliges Aussehen mit verschiedenstem Design verwirklichen läßt.It is also important the feature specified in claim 16 that all handle parts consist of a uniform material, namely plastic. This distinguishes the rotary handle according to the invention fundamentally from the prior art. This not only achieves a particularly simple and inexpensive production, but also an advantageous design means for shape, color and surface quality, so that a pleasing appearance with a wide variety of designs can be achieved.

Ein in seiner Gesamtheit mit 10 bezeichneter Fenstergriff hat, wie aus Fig. 1 ersichtlich ist, einen Griffhals 12 mit einem daran winkelig anschließenden Griff-Hauptteil 14, der innen bzw. unten Fingermulden 15 haben kann. Der Griffhals 12 endet mit einer Schulter 16 und einem daran anschließenden Ansatz 18, der einen Bund 19, eine Ringnut 20 und einen Wulst 21 mit einer End-Fase 22 hat. Achsparallel sind insbesondere vier Schlitze 24 vom Ende des Ansatzes 18 nach oben so geführt, daß sie vor der Schulter 16 enden. An denselben Umfangsstellen des Ansatzes 18 hat dieser, vom Bund 19 ausgehend, als Kerben ausgebildete Rastausnehmungen 26, welche den Flachseiten eines gestrichelt angedeuteten Vierkantloches 28 zugeordnet sind. Dieses nimmt einen Betätigungs-Vierkant B formschlüssig auf, sobald der Griff 10 montiert ist.A window handle designated in its entirety with 10, as can be seen from FIG. 1, has a handle neck 12 with an angularly adjoining main handle part 14, which can have finger recesses 15 on the inside or below. The handle neck 12 ends with a shoulder 16 and an adjoining extension 18 which has a collar 19, an annular groove 20 and a bead 21 with an end chamfer 22. Axially parallel, in particular, four slots 24 are guided upwards from the end of the shoulder 18 so that they end in front of the shoulder 16. At the same circumferential points of the projection 18, starting from the collar 19, the recesses 26 are formed as notches and are assigned to the flat sides of a square hole 28 indicated by dashed lines. This receives an actuating square B positively as soon as the handle 10 is mounted.

Eine mit 30 bezeichnete Anschlagplatte hat eine ebene Deckfläche 31 und an einer dazu parallelen Bodenfläche abstehende Nocken 32, die von Schraublöchern 33 durchsetzt sind. Zentrisch ist eine Buchse 34 vorhanden, in deren Innenumfang Federn 35 mit Nasen 36 einfallen können (Fig. 3). Die Anschlagplatte bildet einen Hohlkörper mit einem Kammersystem, das Längsstege 52 mit schrägen Versteifungen und Stützen 54 aufweist, an welche sich die zur Mittelachse hin gewölbten Stege der Federn 35 anschließen.A stop plate designated by 30 has a flat cover surface 31 and cams 32 projecting from a parallel parallel base surface, which are penetrated by screw holes 33. A bushing 34 is provided centrally, in the inner circumference of which springs 35 with noses 36 can engage (FIG. 3). The stop plate forms a hollow body with a chamber system, which has longitudinal webs 52 with oblique stiffeners and supports 54, to which the webs of springs 35, which are curved toward the central axis, are connected.

Aus Fig. 1 ist ersichtlich, daß sich die Buchse 34 der Anschlagplatte 30 in Axialrichtung A mit einem Lagerring 37 und einer Aussparung 38 fortsetzt.From Fig. 1 it can be seen that the socket 34 of the stop plate 30 continues in the axial direction A with a bearing ring 37 and a recess 38.

Zwischen dem Griffhals 12 und der Anschlagplatte 30 befindet sich eine Abdeckplatte 40, deren Aufbau vor allem aus Fig. 2a, 2b, 2c ersichtlich ist. Sie hat einen umlaufenden Rand 42 und ist einstückig mit einer Feder 44, die von zwei Bögen 46 beiderseits eines Durchgangsloches 48 nahe den Längsseiten 50 gebildet ist. Mit ihrem Scheitel stützen sich die Bögen 46 nach der Montage des Griffes 10 an der Schulter 16 des Griffhalses 12 ab.Between the handle neck 12 and the stop plate 30 there is a cover plate 40, the structure of which can be seen above all from FIGS. 2a, 2b, 2c. It has a peripheral edge 42 and is in one piece with a spring 44, which is formed by two arches 46 on both sides of a through hole 48 near the long sides 50. With their apex, the arches 46 are supported on the shoulder 16 of the handle neck 12 after the assembly of the handle 10.

Das Durchgangsloch 48 erlaubt es, den Ansatz 18 des Griffhalses 12 hindurchzustecken, um ihn mit der Anschlagplatte 30 zu verrasten. Die Einführ-Fase 22 erleichtert es, die sich dabei an den Schlitzen 24 zusammendrückenden Wulst-Teile 21 in die Buchse 34 einzuführen, bis der Lagerring 37 in der Ringnut 20 verrastet ist. Hinterschneidungen sind hierzu im allgemeinen nicht erforderlich, können aber den sicheren Sitz des Ansatzes 18 in der Buchse 34 der Anschlagplatte 30 unterstützen.The through hole 48 allows the neck 18 of the handle neck 12 to be inserted in order to lock it with the stop plate 30. The insertion chamfer 22 makes it easier to insert the bead parts 21, which compress at the slots 24, into the bushing 34 until the bearing ring 37 is locked in the annular groove 20. Undercuts are generally not necessary for this, but can support the secure fit of the extension 18 in the socket 34 of the stop plate 30.

Aus der Druntersicht von Fig. 3 entnimmt man, daß die Nasen 36 der Federn 35 den eingerasteten Ansatz 18 mit den Kerben 26 auch in Umfangsrichtung U festlegen. Die Rastelemente, 26, 36 bewirken im gezeichneten Ausführungsbeispiel eine 90°-Rastung, so daß der Griff-Hauptteil 14 in bezug auf die Anschlagplatte 30 nach oben oder unten sowie nach links oder rechts rastend gestellt werden kann. - Als Variante zu Fig. 1 hat der in Fig. 3 dargestellte Griff-Hauptteil 14 unten bzw. innen keine Fingermulden.From the bottom view of FIG. 3 it can be seen that the lugs 36 of the springs 35 also fix the latched extension 18 with the notches 26 in the circumferential direction U. The latching elements, 26, 36 bring about a 90 ° detent in the illustrated embodiment, so that the handle main part 14 can be placed in relation to the stop plate 30 upwards or downwards and to the left or right. - As a variant of FIG. 1, the main handle part 14 shown in FIG. 3 has no finger depressions at the bottom or inside.

In den Rahmen der Erfindung fallen noch weitere Abwandlungen. Beispielsweise können auch an den Längsseiten der Anschlagplatte 30 oder in anderer Winkelstellung zu der Lagerbuchse 34 Federn mit Rastnasen vorhanden sein. Möglich ist es ferner, an der Abdeckplatte 40 eine Feder 44 anderer Gestaltung vorzusehen, beispielsweise eine umlaufende Wellfeder oder Federbögen auch an den Schmalseiten, gegebenenfalls in Form von Rastnasen, welche in entsprechende Vertiefungen in der Schulter 16 des Griffhalses 12 einfallen können.Further modifications fall within the scope of the invention.
