Description

Die Erfindung betrifft einen Kurbelknopf, insbesondere für Fensterkurbeln von Fahrzeugen, der drehbeweglich auf dem Kurbelzapfen eines Kurbelarmes anordbar ist und eine verdrehfest in einen Durchbruch des Kurbelzapfens schnäpperartig einsteckbare Abzugssperre aufweist, die einendig mit Rastnocken und anderendig einstückig mit einem Flansch ausgebildete Federarme besitzt.The invention relates to a crank knob, in particular for window cranks of vehicles, which can be rotatably arranged on the crank pin of a crank arm and has a trigger lock which can be snapped into a breakthrough of the crank pin and which has spring arms formed at one end with latching cams and at the other end integrally with a flange.

In der deutschen Gebrauchsmusterschrift 74 28 675 ist eine Kurbel mit einem Kurbelknopf beschrieben, der so am Kurbelzapfen gelagert ist, daß die verschleißgefährdeten Stellen gegen ein Verdrehen gesichert sind, womit ein die Funktionstüchtigkeit des Kurbelknopfes beeinträchtigender Materialabrieb verhindert wird. Der Kurbelknopf besitzt eine offene Ausbildung und wird bereichsweise von der gegen Verdrehen gesicherten Abzugssperre übergriffen.The German utility model 74 28 675 describes a crank with a crank knob which is mounted on the crank pin in such a way that the points at risk of wear are secured against twisting, thus preventing material abrasion which impairs the functionality of the crank knob. The crank knob has an open design and is partially covered by the trigger lock, which is secured against twisting.

Der Erfindung liegt die Aufgabe zugrunde, einen Kurbelknopf in geschlossener Bauweise zu schaffen, der mit einer sich als besonders vorteilhaft erwiesenen Abzugssperre nach dem vorgenannten Gebrauchsmuster ausgerüstet ist und dessen Aufbau der Norm für die Gestaltungsanforderungen von Gegenständen in Kraftfahrzeugen (ECE-Norm 21) vollauf gerecht wird.The invention has for its object to provide a crank knob in a closed design, which is equipped with a particularly advantageous trigger lock according to the aforementioned utility model and its structure fully meets the standard for the design requirements of objects in motor vehicles (ECE standard 21) becomes.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß der Kurbelknopf aus einer auf den Kurbelzapfen aufsteckbaren, an einem Stirnende von dem Flansch der Abzugssperre übergriffenen Buchse, einer den Flansch übergreifenden und die Buchse bereichsweise konzentrisch umschließenden Kappe und einem mit der Buchse verankerten, die Kappe einbettenden Kurbelknopfmantel besteht, der aus einem wesentlich weicheren Werkstoff als die übrigen Kurbelknopfteile gebildet ist und eine Härte von max. 5o Shore A aufweist. Ein solchermaßen erfindungsgemäß ausgebildeter Kurbelknopf wird den ECE-Vorschriften insofern vollauf gerecht, als er einen relativ weichen Mantel und einen inneren Kern besitzt, welcher sich mit weichen Radien gestalten läßt.To achieve this object, the invention provides that the crank knob from a plug-on to the crank pin, at one end overlapped by the flange of the trigger lock socket, a cross-over the flange and concentrically enclosing the socket and a cap anchored to the socket, the cap embedding crank button jacket, which is made of a much softer material than the other crank button parts and has a hardness of max. 5o Shore A. A crank knob designed in this way according to the invention fully meets the ECE regulations in that it has a relatively soft jacket and an inner core which can be designed with soft radii.

Die Verbindung des Kurbelknopfmantels mit der inneren Buchse kann durch Aufknöpfen, vorzugsweise aber dadurch erfolgen, daß der Kurbelknopfmantel durch Umspritzen mit der Buchse und der Kappe verankert ist. Die Drehbeweglichkeit des Kurbelknopfmantels mit Buchse auf dem Kurbelzapfen bleibt durch die aufgesetzte Kappe voll erhalten; denn die Abzugssperre wird durch die Kappe gegen überspritzen geschützt.The connection of the crank button jacket to the inner sleeve can be done by unbuttoning, but preferably in that the crank button jacket is anchored to the sleeve and the cap by extrusion coating. The rotatability of the crank button casing with bushing on the crank pin is fully preserved by the attached cap; because the trigger lock is protected against over-splashing by the cap.

Auf dem Flansch der Abzugssperre ist ein zentrischer, punktförmig am Boden der Kappe zur Anlage kommender Nocken angeordnet. Hierdurch wird eine axiale Abstützung der Abzugssperre erzielt und damit ein unkompliziertes Aufstecken des Kurbelknopfes auf den Kurbelzapfen ermöglicht. Durch die nur punktförmige zentrische Berührungsanlage wird die Drehbeweglichkeit des Kurbelknopfes nicht beeinträchtigt.On the flange of the trigger lock there is a central cam which comes into contact at the bottom of the cap. In this way, an axial support of the trigger lock is achieved and thus an uncomplicated attachment of the crank button to the crank pin is made possible. The rotatability of the crank knob is not impaired by the only point-like central touch system.

In zweckmäßiger Ausgestaltung der Erfindung besitzt die Buchse an ihrer außenseitigen Mantelfläche in ringförmiger Anordnung radial nach außen gerichtete Stege, die vollständig im Kugelknopfmantel eingebettet sind. Durch die Stege wird eine Verkrallung des Mantelmaterials mit der Buchse geschaffen. Weiterhin können die Stege als Anschlag für die auf die Buchse aufgesteckte Kappe dienen, indem sich die Kappe mit ihrem offenen Stirnende gegen die Stege abstützt.In an expedient embodiment of the invention, the bushing has on its outer lateral surface in an annular arrangement radially outwardly directed webs which are completely embedded in the spherical button jacket. The webs create a clawing of the jacket material with the socket. Furthermore, the webs can serve as a stop for the cap that is plugged onto the socket, in that the open end of the cap is supported against the webs.

In bevorzugter Ausgestaltung der Erfindung ist der Kurbelknopf ausschließlich aus Kunststoff gebildet. Dabei kann die Buchse und die Kappe vorzugsweise aus PPN, die Abzugssperre vorzugsweise aus POM und der Kurbelknopfmantel aus PVC 50 -5 Shore A bestehen.In a preferred embodiment of the invention, the crank button is made exclusively of plastic. The bushing and the cap can preferably be made of PPN, the trigger lock preferably made of POM and the crank button jacket made of PVC 50 -5 Shore A.

Der Kurbelknopf nach der Erfindung besitzt einen vierteiligen Aufbau, dessen dreiteiliger Kern durch bloßes Zusammenstecken schnell und einfach vormontiert und dessen Mantel durch Umspritzen mit guter Oberflächenbeschaffenheit kostengünstig gebildet werden kann. Er ist ebenfalls schnell und einfach durch Steckmontage montierbar, besitzt eine bleibend funktionstüchtige Abzugssicherung und ist durch die radiale Festlegung der Abzugssperre einem nur vernachlässigbar kleinen Abriebverschleiß ausgesetzt. Der Kurbelknopf erfüllt damit die ECE-Vorschriften in optimaler Weise.The crank knob according to the invention has a four-part structure, the three-part core can be preassembled quickly and simply by simply plugging it together and the jacket can be formed inexpensively by extrusion coating with a good surface finish. It is also quick and easy to assemble by means of plug-in assembly, has a permanently functional trigger lock and is exposed to only negligible wear due to the radial locking of the trigger lock. The crank knob thus optimally fulfills the ECE regulations.

Die Zeichnung zeigt ein Ausführungsbeispiel eines Kurbelknopfes nach der Erfindung, wobei

  • Fig. 1 einen Vertikal-Schnitt und
  • Fig. 2 eine Draufsicht nach Fig. 1 darstellt.
The drawing shows an embodiment of a crank knob according to the invention, wherein
  • Fig. 1 is a vertical section and
  • FIG. 2 shows a top view according to FIG. 1.

Der Kurbelknopf besteht aus einer Buchse 1, einer Abzugssperre 2, einer Kappe 3 und aus einem Kurbelknopfmantel 4. Die Buchsenöffnung 5 ist im Durchmesser zur Aufnahme eines Kurbelzapfens ausgebildet. Sie weist an ihrem Außenmantel in'ringförmiger Anordnung angeformte Stege 6 auf, die eine hakenförmige Gestaltung besitzen und einmal zur Verkrallung im Kurbelknopfmantel 4 und einmal als Anschlag für das offene Stirnende der Kappe 3 dienen.The crank knob consists of a bushing 1, a trigger lock 2, a cap 3 and a crank knob jacket 4. The bushing opening 5 is designed in diameter to receive a crank pin. It has integrally formed webs 6 on its outer jacket in an annular arrangement, which have a hook-shaped design and serve once for clawing in the crank button jacket 4 and once as a stop for the open front end of the cap 3.

Die Abzugssperre 2 besitzt einen sich auf dem oberen Stirnende der Buchse 1 abstützenden Flansch 9, an dessen Unterseite Federarme 7 angeformt sind, deren freie Enden Rastnocken 8 aufweisen. Durch die mit Rastnocken 8 ausgebildeten Federarme 7 wird der Kurbelknopf an einen Kurbelzapfen gegen Abziehen gesichert, festgelegt. Der im nicht dargestellten Kurbelzapfen vorgesehene Durchbruch, der mit den Federarmen 7 zusammenwirkt, ist zweckmäßigerweise vierkantig ausgebildet und dieser Ausbildung sind die Federarme 7 angepaßt. Damit wird durch die Federarme 7 neben einer Abzugssicherung auch eine Verdrehsicherung der Abzugssperre 2 erzielt. Das bedeutet, daß sich beim montierten Kurbelknopf nur die Teile 1, 3 und 4 um den Kurbelzapfen drehen können, während die Abzugssperre 2 sich nicht drehen kann. Damit ist ein Abriebverschleiß weitgehend vermieden.The trigger lock 2 has a flange 9 which is supported on the upper end face of the bushing 1 and on the underside of which spring arms 7 are formed, the free ends of which have locking cams 8. By the spring arms 7 formed with locking cams 8, the crank button is secured to a crank pin against pulling out. The opening provided in the crank pin, not shown, which interacts with the spring arms 7, is expediently square and the spring arms 7 are adapted to this design. In addition to a trigger lock, the spring arms 7 also secure the trigger lock 2 against rotation. This means that when the crank knob is installed, only parts 1, 3 and 4 can rotate around the crank pin, while the trigger lock 2 cannot rotate. Abrasion wear is largely avoided.

Wie die Zeichnung weiterhin zeigt, besitzt der Flansch 9 der Abzugssperre 2 außenseitig einen zentrisch angeformten kegelförmig ausgebildeten Nocken 10, der sich am Boden der Kappe 3 abstützt. Der Boden 3 kann zur einwandfreien Zentrierung eine konkave Eindrückung aufweisen, in die der Nocken 10 eingreift.As the drawing also shows, the flange 9 of the trigger lock 2 has on the outside a centrally formed conical cam 10 which is supported on the bottom of the cap 3. The bottom 3 can have a concave indentation in which the cam 10 engages for perfect centering.

Der Kurbelknopf besitzt einen aus der Zeichnung ersichtlichen vierteiligen Aufbau, wobei der dreiteilige Kern durch Stecken zusammengefügt wird, wonach der Kurbelknopfmantel 4 durch Umspritzen des dreiteiligen Kernes mit einem relativ weichen Kunststoffmaterial gebildet wird.The crank knob has a four-part structure as can be seen from the drawing, the three-part core being joined by plugging, after which the crank knob jacket 4 is formed by extrusion-coating the three-part core with a relatively soft plastic material.
