Description

Die Erfindung betrifft eine Handhabe zum Bedienen von Fenstern, Türen od. dgl. mit einer Befestigungsplatte, insbesondere einer Lagerrosette, wobei diese Befestigungsplatte aus einem Grundkörper besteht, der zum einen eine zentrische Lagerbuchse aufweist, in der der Handgriff drehbar gelagert und axial fest angebracht ist und der andererseits über ihn durchdringende Schrauben od. dgl. eine Befestigung, vornehmlich am Flügel der Tür oder des Fensters od. dgl. erlaubt, sowie eine Abdeckkappe hat, die ebenfalls um die Achse des Griffhalses drehbar angeordnet ist und zur Abdeckung der Befestigungsschrauben od. dgl. dient, wobei sich die Abdeckkappe federnd an einer Schulter bzw. Widerlagerfläche des Griffhalses abstützt und wobei die Abdeckkappe aus einem federharten Werkstoff, z.B. Kunststoff oder Metall, bestehtThe invention relates to a handle for operating windows, doors or the like. With a mounting plate, in particular a mounting rosette, this mounting plate consists of a base body which has a central bearing bush in which the handle is rotatably mounted and axially fixed and on the other hand penetrating screws or the like. An attachment, primarily on the wing of the door or window or the like. Permitted, and has a cover cap, which is also rotatably arranged about the axis of the handle neck and to cover the fastening screws or. The like. Serves, the cover cap is resiliently supported on a shoulder or abutment surface of the handle neck and the cover cap made of a spring-hard material, for example Plastic or metal

Handhaben der vorgenannten Art zur Bedienung von Fenstern und Türen od. dgl. sind in verschiedenen Bauarten bekannt, wie beispielsweise durch die EP-A1 0 406 566 und EP-A1 0 417 032 belegt ist.Handling of the aforementioned type for operating windows and doors or the like are known in various designs, as evidenced for example by EP-A1 0 406 566 and EP-A1 0 417 032.

In der EP-A1 0 417 032 wird eine Handhabe beschrieben, deren Abdeckkappe aus einem federharten Werkstoff besteht und die mit Federelementen versehen ist, welche aus zungenförmig unmittelbar aus der Ebene der Abdeckkappe hergestellten Materialabschnitten derselben gebildet sind sowie unter Vorspannung mit ihren freien Enden an einer Widerlagerfläche des Bedienungsgriffhalses anliegen.EP-A1 0 417 032 describes a handle whose cover cap consists of a spring-hard material and which is provided with spring elements which are formed from material sections of the same made of tongue-like material directly from the plane of the cover cap and below Bias with its free ends against an abutment surface of the operating handle neck.

Mit der DE-A 39 35 074 wird vorgeschlagen, daß mindestens ein Federelement zum Andruck der Abdeckkappe einteilig mit dieser oder dem Grundkörper ausgebildet ist. In der EP-A 0 406 566 wird eine Bauart beschrieben, bei der die schwenkbare Abdeckkappe mit einer als Andruckelement dienenden Biegefeder einstückig ist, wobei die Biegefeder sich an einer Schulter des Griffhalses abstützt.DE-A 39 35 074 proposes that at least one spring element for pressing the cover cap is formed in one piece with it or with the base body. EP-A 0 406 566 describes a type in which the pivotable cover cap is made in one piece with a spiral spring serving as a pressure element, the spiral spring being supported on a shoulder of the handle neck.

Diese bekannten Handhaben weisen aber verschiedene Nachteile auf. So erfordern sie z.B. einen hohen Montage- und Teileaufwand, wenn Abdeckkappen und Federelemente voneinander getrennt hergestellt, gelagert und gehandhabt werden müssen. Darüber hinaus sind die Federelemente - insbesondere dann, wenn sie baueinheitlich mit der Abdeckkappe und/oder dem Grundkörper gefertigt werden - empfindlich gegen zu hohen Montagedruck. In einem solchen Falle geht die vorgegebene Elastizität verloren, d.h., die Wirkungsweise der Abdeckkappe wird zumindest erheblich beeinträchtigt.However, these known manipulations have various disadvantages. For example, they require high assembly and parts costs if cover caps and spring elements have to be manufactured, stored and handled separately. In addition, the spring elements - especially when they are manufactured in a unitary manner with the cover cap and / or the base body - are sensitive to excessive installation pressure. In such a case, the specified elasticity is lost, i.e. the operation of the cover cap is at least significantly impaired.

Ziel der Erfindung ist es daher, eine Handhabe zur Bedienung von Fenstern, Türen od. dgl. der eingangs spezifizierten Gattung anzugeben, die nur wenige Einzelteile erfordert, trotzdem aber auf einfache Art und Weise und ohne zusätzliche Federelemente eine selbsttätige, dauerhaft drehsichere Fixierung der Abdeckkappe in ihrer Abdeckstellung vor der Stirnseite des Grundkörpers gewährleistet. Dabei soll die Montage der Handhabe so möglich sein, daß die beschriebenen Mängel nicht auftreten und insbesondere ein Axialspiel der Handgriff-Lagerung relativ zum Grundkörper der Befestigungsplatte bzw. Lagerrosette unterbunden wird.The aim of the invention is therefore to provide a handle for operating windows, doors or the like. Of the type specified at the outset, which requires only a few individual parts, but nevertheless, in a simple manner and without additional spring elements, an automatic, permanently rotationally secure fixing of the cover cap guaranteed in their covering position in front of the front of the base body. It should be possible to assemble the handle so that the deficiencies described do not occur and in particular an axial play of the handle mounting relative to the base body of the mounting plate or mounting rosette is prevented.

Die Erfindung erfüllt diese Zwecke mit den Kennzeichnungsmerkmalen des Anspruchs 1 in der Weise, daß die zum Andruck auf die Grundplatte notwendige Kraft durch eine Wölbung der Abdeckkappe erreicht wird. Die Abdeckkappe stützt sich dabei mit den Stirnseiten der einteilig mit ihr ausgebildeten Buchse sowohl gegen die Schulter des Griffhalses als auch gegen die Stirnfläche des Grundkörpers ab und verhindert dadurch auf einfache, aber wirksame Art und Weise ein Axialspiel der Handgriff-Lagerung in der Befestigungsplatte bzw. Lagerrosette. Es wird zum einen gewährleistet, daß die Abdeckkappe unter der kreisringförmigen Belastung gleichmäßig gegen die Grundplatte angedrückt ist. Zum anderen ist aber auch erreicht, daß die Andruckkräfte auf eine größere Fläche sowohl am Griffhals als auch auf der Abdeckkappe übertragen werden. Dies verringert die Gefahr, daß sich während des Transportes oder einer Vorbehandlung die Federkraft durch eine plastische Verformung verändert. Durch die Buchsenform wird auch erreicht, daß die Verdrehung der Abdeckkappe mühelos möglich ist, weil die Kappe zu jedem Zeitpunkt zentrisch geführt wird. Es wird damit gewährleistet, daß die Abdeckkappe mit ihrem Umfangsrand auch an den dafür vorgesehenen Stellen auf der ebenen Stirnfläche der Befestigungsplatte bzw. Lagerrosette paßgenau bzw. dicht aufsitzt. Grundsätzlich ist es auch möglich, den Griffhals in der Art auszubilden, daß der dem Griffhals zugewandte Abschnitt der Buchse in einer im Griffhals befindlichen Nut verschwindet. Dadurch wird der Spalt zwischen Griffhals und Abdeckplatte minimiert, was die Ästhetik der Handhabe fördert. Auch werden die durch die Benutzung der Handhabe unvermeidlichen (schwarzen) Abriebpartikel auf den sichtbaren Flächen keine Spuren hinterlassen, da die aufeinanderreibenden Flächen verborgen sind.The invention fulfills these purposes with the characterizing features of claim 1 in such a way that the force required for pressing on the base plate is achieved by a curvature of the cover cap. The cover cap is supported with the end faces of the bushing, which is formed in one piece with it, both against the shoulder of the handle neck and against the end face of the base body and thereby prevents axial play of the handle bearing in the fastening plate or in a simple but effective manner. Bearing rosette. It is ensured on the one hand that the cover cap is pressed evenly against the base plate under the annular load. On the other hand, it is also achieved that the pressure forces are transmitted to a larger area both on the handle neck and on the cover cap. This reduces the risk that the spring force changes due to plastic deformation during transport or pretreatment. The shape of the bush also ensures that the cover cap can be easily rotated because the cap is guided centrally at all times. It is thus ensured that the covering cap with its peripheral edge also fits snugly or tightly at the places provided on the flat end face of the mounting plate or bearing rosette. In principle, it is also possible to design the handle neck in such a way that the section of the socket facing the handle neck disappears in a groove located in the handle neck. This minimizes the gap between the handle neck and cover plate, which promotes the aesthetics of the handle. Also, the (black) abrasion particles that are unavoidable due to the use of the handle will not leave any traces on the visible surfaces, since the surfaces rubbing against each other are hidden.

Als vorteilhaft hat sich die Ausführung der Abdeckkappe aus Kunststoff erwiesen. Dessen Eigenschaften machen es nämlich möglich, ohne großen Aufwand die zur Erzeugung der Vorspannung notwendige Wölbung, auch bei geringer Wandstärke der Abdeckkappe, zu erzeugen.The design of the plastic cover cap has proven to be advantageous. Its properties make it possible to produce the curvature required to generate the prestressing, even with a small wall thickness of the cover cap, without great effort.

Das in den Fig. 1 und 2 dargestellte Ausführungsbeispiel einer Bedienungshandhabe für Fenster, Türen od. dgl. weist als Hauptbestandteile eine Befestigungsplatte bzw. Lagerrosette 2 und den an bzw. in dieser gehaltenen Bedienungsgriff 5 auf. Die Befestigungsplatte bzw. Lagerrosette 2 hat dabei wiederum einen Grundkörper 3 und eine dessen Stirnseite zugeordnete Abdeckkappe 4. Über den Grundkörper 3 der Befestigungsplatte bzw. Lagerrosette 2 läßt sich die Handhabe 1 insbesondere an dem öffenbaren Flügel 6 des Fensters oder der Tür befestigen, und zwar mit Hilfe von - nicht dargestellten - Schrauben, welche jeweils durch ein Durchgangsloch 7 des Grundkörpers 3 hindurchgeführt sind.The exemplary embodiment of an operating handle for windows, doors or the like shown in FIGS. 1 and 2 has as its main components a mounting plate or bearing rosette 2 and the operating handle 5 held on or in this. The mounting plate or bearing rosette 2 in turn has a base body 3 and a cover cap associated with its end face 4. About the base body 3 of the mounting plate or bearing rosette 2, the handle 1 can be attached in particular to the openable wing 6 of the window or the door, namely with the help of - not shown - screws, which are each passed through a through hole 7 of the base body 3.

Konzentrisch zu jedem Loch 7 im Grundkörper 3 ragt von dessen Rückseite ein Nocken oder Dorn 8 ab, welcher zur formschlüssigen Drehsicherung des Grundkörpers 3 der Befestigungsplatte 2 am Flügel 6 jeweils in eine stirnseitig offene Bohrung 9 des letzteren eingreift, wie das deutlich in Fig. 2 zu sehen ist. Der Bedienungsgriff 5 weist einen vom eigentlichen Griffschaft 10 gegen die Befestigungsplatte bzw. Lagerrosette 2 hin abgewinkelten Schaftabschnitt 11 auf, an den sich einstückig ein Griffhals 12 als Lagerteil anschließt. Dabei hat der Griffhals 12 eine die Befestigungsplatte bzw. Lagerrosette 2 zugewendete Widerlagerfläche 13. Der Griffhals 12 am freien Ende des Schaftabschnittes 11 durchgreift eine Lagerbuchse 14, die von der Rückseite des Grundkörpers 3 durch ein Zentralloch 15 einer einstückig mit dem Grundkörper 3 ausgeführten und von dessen Stirnseite abstehenden Lagertülle 16 hindurchgeführt ist. Mit einem Stützbund 17 liegt dabei die Lagerbuchse 14 in einer Vertiefung an der Rückseite des Grundkörpers 3 stützend an, während der Griffhals 12 des Bedienungsgriffs 5, beispielsweise durch eine Bördelung oder Stauchung 18, axial unverschiebbar gegen den Stützbund 17 der Lagerbuchse 14 festgelegt ist. Aus der Rückseite der Befestigungsplatte bzw. Lagerrosette 2 bzw. aus deren Grundkörper 3 ragt ein Antriebsdorn 25 heraus, der in Achsfluchtlage mit dem Griffhals 12 drehfest im abgewinkelten Schaftabschnitt 11 des Bedienungsgriffes 5 fixiert ist.Concentrically to each hole 7 in the base body 3, a cam or mandrel 8 protrudes from the rear side thereof, which engages in a frontally open bore 9 of the latter for positive locking of the base body 3 of the fastening plate 2 on the wing 6, as clearly shown in FIG. 2 you can see. The operating handle 5 has a shaft section 11 which is angled away from the actual handle shaft 10 against the fastening plate or bearing rosette 2 and to which a handle neck 12 is connected in one piece as a bearing part. The handle neck 12 has an abutment surface 13 facing the mounting plate or bearing rosette 2. The handle neck 12 at the free end of the shaft section 11 passes through a bearing bush 14, which is made from the rear of the base body 3 through a central hole 15 of one piece with the base body 3 and from whose end protruding bearing sleeve 16 is passed. With a support collar 17, the bearing bush 14 rests in a recess on the back of the base body 3, while the handle neck 12 of the operating handle 5, for example by flanging or compression 18, is axially fixed against the support collar 17 of the bearing bush 14. A drive pin 25 protrudes from the rear of the mounting plate or bearing rosette 2 or from its base body 3, which is fixed in the axial alignment with the handle neck 12 in the angled shaft section 11 of the operating handle 5 in a rotationally fixed manner.

Die Abdeckkappe 4 der Befestigungsplatte bzw. Lagerrosette 2 ist vorgesehen, um die an der Stirnseite des Grundkörpers 3 jeweils mit einem Versenk ausmündenden Durchgangslöcher 7 zur Aufnahme der Befestigungsschrauben bei am Fenster bzw. an der Tür angebrachter Handhabe 1 abdecken zu können, sobald in diese die Befestigungsschrauben zur Halterung des Grundkörpers 3 am Flügel 6 in der üblichen Weise eingesetzt worden sind.The cover cap 4 of the mounting plate or mounting rosette 2 is provided in order to be able to cover the through holes 7 opening at the front of the base body 3 with a countersink for receiving the mounting screws when the handle 1 is attached to the window or the door, as soon as the Fastening screws for holding the base body 3 on the wing 6 have been used in the usual manner.

Die Abdeckkappe 4 ist zu diesem Zweck konzentrisch zur Längsachse des Griffhalses 12 am Bedienungsgriff 5 verdrehbar auf der Lagertülle 16 des Grundkörpers 3 angeordnet. Sie weist dabei ein auf den Durchmesser der Lagertülle 16 abgestimmtes Rundloch 19 auf, das insbesondere in den Fig. 3 und 4 zu sehen ist. Die Abdeckkappe 4 ist in ihrer Umrißform auf die Umrißform des Grundkörpers 3 abgestimmt und wird aus einem federharten Werkstoff, z.B. Kunststoff oder Metall, hergestellt. Die Fertigung der Abdeckplatte 4 aus federhartem Kunststoff ist durch Spritzgießen in einer Form möglich.For this purpose, the cover cap 4 is rotatably arranged on the bearing sleeve 16 of the base body 3 concentrically to the longitudinal axis of the handle neck 12 on the operating handle 5. It has a round hole 19 which is matched to the diameter of the bearing sleeve 16 and which can be seen in particular in FIGS. 3 and 4. The cover cap 4 is matched in its outline shape to the outline shape of the base body 3 and is made of a spring-hard material, e.g. Plastic or metal. The cover plate 4 can be made from spring-hard plastic by injection molding in a mold.

Die Abdeckkappe 4 hat vorzugsweise die Form einer Mulde mit konvexer Eigenkrümung oder -wölbung und weist an ihrer Rückseite einen umlaufenden Randbord 20 auf. Mit den Endkanten dieses Randbordes 20 kann sich die Abdeckkappe 4 gegen die eben ausgebildete Stirnfläche des Grundkörpers 3 abstützen, sobald Abdeckkappe 4 und Grundkörper 3 miteinander in eine konturengleiche Deckungslage gebracht sind.The cover cap 4 preferably has the shape of a trough with a convex intrinsic curvature or curvature and has a peripheral rim 20 on its rear side. With the end edges of this rim 20, the cover cap 4 can be supported against the end face of the base body 3 which has just been formed as soon as the cover cap 4 and base body 3 are brought into a cover position of the same contour.

Zur drehsicheren Fixierung der Abdeckkkappe 4 gegenüber dem Grundkörper 3 in ihrer die Durchgangslöcher 7 bzw. die in deren Versenk aufgenommenen Schraubenköpfe abdeckenden Drehstellung kommen lediglich bestimmte Querkanten-Bereiche 24 des an der Rückseite der Abdeckkappe 4 befindlichen Randbordes 20 mit entsprechend abgesetzten, beispielsweise angeschrägten Aufnahmen 21 am Grundkörper 3 in Formschlußeingriff, wie das die Fig. 2 der Zeichnung erkennen läßt.For the rotationally secure fixing of the cover cap 4 with respect to the base body 3 in its rotational position covering the through holes 7 or the screw heads accommodated in its recess, only certain transverse edge regions 24 of the rim 20 located on the rear side of the cover cap 4 come with correspondingly offset, for example beveled receptacles 21 on the base body 3 in positive engagement, as can be seen in FIG. 2 of the drawing.

Zwecks selbsttätiger Herstellung dieses Formschlußeingriffes zwischen dem Randbord 20 der Abdeckkappe 4 und dem abgesetzten Umfangsrand 21 des Grundkörpers 3 ist die aus dem federharten Werkstoff bestehende Abdeckkappe 4 im Randbereich ihres Rundloches 19 mit einer sich sowohl in Richtung der Grundplatte 3 als auch in Richtung des Griffhalses 12 erstreckenden Buchse 22 versehen, die zusammen mit einer vorgegebenen, z.B. vorgeformten Wölbung der Abdeckkappe 4 gesamteinheitlich ein axialelastisches Federelement bildet. Dabei stützt sich die Buchse 22 mit der Kreisringfläche 23 unter Vorspannung an der Widerlagerfläche 13 ab, welche den Übergang zwischen dem abgewinkelten Schaftabschnitt 11 des Bedienungsgriffes 5 und dessen Griffhals 12 bildet.For the purpose of automatic production of this positive engagement between the rim 20 of the cover cap 4 and the stepped peripheral edge 21 of the base body 3, the cover cap 4, which is made of spring-hard material, is in the edge region of its round hole 19 with one in the direction of the base plate 3 and in the direction of the handle neck 12 extending bushing 22 which, together with a predetermined, for example preformed, curvature of the covering cap 4 forms an axially elastic spring element as a whole. The bushing 22 is supported with the annular surface 23 under prestress on the abutment surface 13, which forms the transition between the angled shaft section 11 of the operating handle 5 and its handle neck 12.

Sobald die Abdeckkappe 4 mit ihrer Umrißform exakte Deckungslage zur Umrißform des Grundkörpers 3 einnimmt, wirkt sie gesamtheitlich als Federelement zwischen der ebenen Stirnfläche des Grundkörpers 3 und der die radiale Widerlagerfläche des Griffhalses 12 bildenden Schulter bzw. Kreisringfläche 23. Die Endkanten des rückwärts gerichteten Randbordes 20 kommen satt und dicht längs des Umfangsrandes des Grundkörpers 3 auf dessen ebener Stirnfläche zur Auflage, während nur die an den beiden Querkanten-Bereichen des Randbordes 20 als Randvorsprünge 24 vorhandenen Nasen od. dgl. in die zugehörigen Randeinschnitte 21 an den kürzeren Umfangskanten des Grundkörpers 3 einrücken, um dort für einen der Drehsicherung der Abdeckkappe 4 dienenden Formschluß zu sorgen.As soon as the cover cap 4 with its outline shape assumes an exact cover position with respect to the outline shape of the base body 3, it acts as a whole as a spring element between the flat end face of the base body 3 and the shoulder or annular surface 23 forming the radial abutment surface of the handle neck 12. The end edges of the rearward-facing rim 20 come to rest fully and tightly along the circumferential edge of the base body 3 on its flat end face, while only the noses or the like present on the two transverse edge regions of the edge rim 20 as edge projections 24 in the associated edge incisions 21 on the shorter peripheral edges of the base body 3 engage in order to ensure that the form-locking means of the cap 4 are secured against rotation.

Der Abstand zwischen der Widerlagerfläche 13 am abgewinkelten Schaftabschnitt 10 des Bedienungshandgriffs 5 und der Stirnfläche der Abdeckkappe 4 entspricht der Höhe der Buchse 22. Er ist in der Fixierlage am Grundkörper 3 so bemessen, daß sich die Abdeckkappe 4 von Hand entgegen der ihr infolge der Wölbung innewohnenden eigenen Federwirkung mindestens im Bereich ihrer kurzen Querkanten elastisch anheben läßt, und zwar so weit, daß die Randvorsprünge bzw. Nasen 24 ihres Randbordes 20 mit den Randeinschnitten bzw. Aufnahmen 21 des Grundkörpers 3 außer Eingriff gelangen. Dabei haben die Randvorsprünge bzw. Nasen 24 die zusätzliche Aufgabe, die für das Anheben notwendigen Handkräfte großflächiger und damit besser ansetzen und übertragen zu können. Nach dem Anheben der Querkanten kann die Abdeckkappe 4 um die Lagertülle 16 des Grundkörpers 3 aus der Abdeckstellung nach Fig. 1 so weit - z.B. um 90° - verdreht werden, daß die Versenke der Durchgangslöcher 7 und damit die Senkköpfe der Befestigungsschrauben freigelegt werden. Dadurch sind die Schraubenköpfe für die Betätigung mit einem Schraubendreher zugänglich.The distance between the abutment surface 13 on the angled shaft section 10 of the operating handle 5 and the end face of the cover cap 4 corresponds to the height of the socket 22. It is dimensioned in the fixing position on the base body 3 so that the cover cap 4 by hand against it due to the curvature inherent own spring action can be raised elastically at least in the region of their short transverse edges, to the extent that the edge projections or lugs 24 of their edge flange 20 disengage from the edge incisions or receptacles 21 of the base body 3. The edge projections or lugs 24 have the additional task of being able to apply and transmit the hand forces required for lifting over a larger area and thus better. After lifting of the transverse edges, the cover cap 4 can be rotated around the bearing bush 16 of the base body 3 from the cover position according to FIG. 1, for example by 90 °, so that the recesses in the through holes 7 and thus the countersunk heads of the fastening screws are exposed. This means that the screw heads are accessible for operation with a screwdriver.
