Description

Die Erfindung betrifft eine Kurbelstange für Markisen nach dem Oberbegriff des Patentanspruches 1 sowie eine Öse für solche Kurbelstangen.The invention relates to a crank rod for awnings according to the preamble of Claim 1 and an eyelet for such crank rods.

Bei herkömmlichen Kurbelstangen der eingangs genannten Art, wie sie z.B. in der DE 4 216 800 A1 beschrieben sind, weist das freie Ende der Partie eine nach unten abgebogene Nase auf, wobei die zylinderförmige und gleichen Durchmesser aufweisende Partie der Kurbelstange mit den Mantelflächen zweier Kegelstümpfe in Druckverbindung steht. Die gewünschte Verdrehbarkeit der Öse ist zwar gewährleistet, jedoch mit erheblichem Kraftaufwand, und zwar vor allem dann, wenn der Winkel zwischen der Drehachse der Öse und der Längsachse der Kurbelstange wächst. In solchen Fällen kann sich die Partie in der Öse in ihrer Achsrichtung verschieben, was unerwünscht ist.In the case of conventional crank rods of the type mentioned at the beginning, such as in the DE 4 216 800 A1, the free end of the lot has one nose bent down on, being cylindrical and equal in diameter Showing part of the crank rod with the outer surfaces of two truncated cones is in pressure connection. The desired rotatability of the eyelet is true guaranteed, but with considerable effort, especially when when the angle between the axis of rotation of the eyelet and the longitudinal axis of the Crank rod grows. In such cases, the lot in the eyelet can be in its Shift axis direction, which is undesirable.

Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, hier Abhilfe zu schaffen.Starting from the above prior art, the object of the invention based on remedying this.

Die gestellte Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 bzw. Anspruches 11 gelöst.The object is achieved by the features of the claim 1 and claim 11 solved.

Man erkennt, daß die Erfindung jedenfalls dann verwirklicht ist, wenn die von der Kurbelstange herrührende Kraft im wesentlichen voll auf die Öse weitergeleitet werden kann, und zwar im wesentlichen unabhängig davon, welchen Arbeitswinkel die Drehachse der Öse mit der Achse der Kurbelstange einschließt. Durch die Form der Verdickungen und der Flächen ist gewährleistet, daß es zu keiner Verschiebung der Partie innerhalb der Öse kommt. Es handelt sich vielmehr um eine Art von Kardan-Gelenk, bei dem die Verdickungen auf den Innenflächen mit einem Freiheitsgrad abrollen bzw. abwälzen, ohne in Richtung der Partie-Achse verschoben zu werden.It can be seen that the invention is in any case implemented if that of The force from the crank rod is essentially fully transmitted to the eyelet can be, regardless of the working angle includes the axis of rotation of the eyelet with the axis of the crank rod. By the shape The thickening and the areas ensure that there is no displacement the lot comes inside the eyelet. Rather, it is a type of Cardan joint, where the thickening on the inner surfaces with a Roll or roll off the degree of freedom without moving in the direction of the lot axis to be moved.

Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous embodiments of the invention are based the subclaims.

Eine besonders zweckmäßige Ausgestaltung sieht vor, daß die Verdickungen mit Abstand zueinander und auf entgegengesetzten Seiten der Öse angeordnet sind. Desweiteren ist es zweckmäßig, wenn die Arbeitsflächen der Verdickungen auf die Form der Arbeitsflächen der Öse abgestimmt sind. Im Rahmen dieses Erfindungsgedankens ist es besonders zweckmäßig, wenn die einander zugewandten Arbeitsflächen der Verdickungen und der Ösen komplementär zueinander ausgebildet sind. Durch den erreichten Kraft- und Formschluß zwischen den Arbeitsflächen und den Flächen kommt es zu keinem Verrutschen der Verdickungen innerhalb der Öse. Die Verdickungen werden insbesondere in den nutartigen Flächen geführt.A particularly useful embodiment provides that the thickening with Distance to each other and on opposite sides of the eyelet. Furthermore, it is expedient if the working surfaces of the thickened areas Shape of the work surfaces of the eyelet are matched. As part of this The inventive concept, it is particularly useful if the each other complementary working surfaces of the thickening and the eyelets are trained to each other. Due to the positive and positive engagement between the work surfaces and the surfaces do not slip Thickening inside the eyelet. The thickenings are particularly in the guided groove-like surfaces.

Ferner sieht eine besonders zweckmäßige Ausgestaltung der Erfindung vor, daß die Verdickungen in Form von Kugelabschnitten ausgebildet sind, wobei es bezüglich einer minimalen Reibung von Vorteil ist, wenn die Verdickungen an den Partien drehbar gelagert sind. Furthermore, a particularly useful embodiment of the invention provides that the Thickenings are formed in the form of spherical sections, it With regard to minimal friction, it is advantageous if the thickenings on the Batches are rotatably mounted.

In den Fig. 1 bis 3 ist eine Kurbelstange 10mit einer um ihre Längsachse 12 verdrehbaren und quer zur Längsachse 12 sich erstreckenden Partie 16 zum Betätigen einer Öse 30 dargestellt. Die Öffnung 32 der Öse 30 hat einen kreisrunden Innenumriß und weist zwei in etwa kegelstumpfförmige, koaxial zueinander angeordnete und über ihre einander zugewandten Enden in die gemeinsame Öffnung 32 mündende rotationssymmetrische Flächen 36 auf. Die eine Verdickung 22 aufweisende Partie 16 ist in die Öffnung 32 einführbar. Die Partie 16 weist ferner eine zweite Verdickung 20 auf, wobei die Verdickungen 20 und 22 mit jeweils einer der Flächen 36 zusammenarbeiten können, was der Fig. 2 zu entnehmen ist. Die Verdickungen 20 und 22 sind mit Abstand d4 zueinander angeordnet, wobei die Arbeitsflächen 26 und 28 der Verdickungen 20 und 22 auf die Form der Flächen 36 abgestimmt sind. Dieser Abstand d4 kann im Bedarfsfall ganz gering gehalten werden, so daß zwischen den Verdickungen 20 und 22 nur ein Spalt ausgebildet ist, der im Querschnitt die Form einer Doppelschwinge aufweist. Die Verdickungen können angefast sein. Die einander zugewandten Partien der Arbeitsflächen 26, 28 und der Flächen 36 sind komplementär zueinander ausgebildet. Im vorliegenden Ausführungsbeispiel sind die Arbeitsflächen 26 und 28 konvex und die Flächen 36 konkav ausgebildet, was eine einfache und schnelle Herstellung der Verdickungen sowie der Öse z.B. durch Gießen bzw. Spritzen ermöglicht. Die Verdickungen 20 und 22 sind in Form von Kugelabschnitten ausgebildet, wobei der Außendurchmesser der Kugelabschnitte geringfügig kleiner ist als der Innendurchmesser d1 der Öse 30. Die Verdickungen 20, 22 sind ferner mit Bezug auf die Achse 12 symmetrisch angeordnet, so daß eine optimale Kräfteübertragung von der Kurbelstange 10 auf die Öse 30 erfolgen kann. Ferner lassen die Figuren erkennen, daß die Verdickungen 20 und 22 einstückig mit der Partie 16 ausgebildet sind, wobei sie ganz allgemein auch drehbar um die Längsachse 24 der Partie gelagert sein könnten. Die Drehachse 8 der Öse kann mit der Drehachse 12 einen Winkel einschließen, der bis zu 45 Grad beträgt.1 to 3 is a crank rod 10 with a around its longitudinal axis 12 rotatable and transverse to the longitudinal axis 12 extending portion 16 to Operating an eyelet 30 shown. The opening 32 of the eyelet 30 has one circular inner contour and has two approximately frusto-conical, coaxial arranged to each other and over their mutually facing ends in the Common opening 32 opening rotationally symmetrical surfaces 36. The a portion 16 having a thickened portion 22 can be inserted into the opening 32. The Batch 16 also has a second thickening 20, the thickening 20 and 22 can cooperate with one of the surfaces 36, which is shown in FIG. 2 can be seen. The thickenings 20 and 22 are at a distance d4 from one another arranged, the working surfaces 26 and 28 of the thickenings 20 and 22 on the shape of the surfaces 36 are coordinated. This distance d4 can if necessary be kept very low, so that between the thickenings 20 and 22 only a gap is formed which has the shape of a double rocker in cross section having. The thickenings can be chamfered. The facing each other Batches of work surfaces 26, 28 and surfaces 36 are complementary trained to each other. In the present embodiment, the Work surfaces 26 and 28 are convex and the surfaces 36 are concave, which is a simple and quick production of the thickening and the eyelet e.g. by Pouring or spraying enables. The thickenings 20 and 22 are in the form of Ball sections formed, the outer diameter of the ball sections is slightly smaller than the inner diameter d1 of the eyelet 30. The thickening 20, 22 are also arranged symmetrically with respect to the axis 12, so that optimal transmission of forces from the crank rod 10 to the eyelet 30 take place can. Furthermore, the figures show that the thickenings 20 and 22nd are integrally formed with the lot 16, and in general also could be rotatably supported about the longitudinal axis 24 of the lot. The axis of rotation 8 the eye can form an angle with the axis of rotation 12 of up to 45 degrees is.

Die Öse 16 ist in bezug auf ihre Drehachse 8 ein symmetrischer Körper mit kreisrunder Öffnung 32. Die Flächen 36 sind nach innen gewölbt und verjüngen sich zur Öffnung 32 hin. Von der Geometrie her sind diese Flächen 36 Mantelflächen eines sphärischen Kegelstumpfes, dessen Mantellinien bogenförmig sind. Die Grundflächen 33 dieses Kegelstumpfes sind voneinander abgewandt.The eyelet 16 is a symmetrical body with respect to its axis of rotation 8 circular opening 32. The surfaces 36 are curved inward and taper towards opening 32. In terms of geometry, these surfaces are 36 Shell surfaces of a spherical truncated cone, the surface lines of which are curved are. The base surfaces 33 of this truncated cone face away from one another.

Der mittlere Abschnitt 34 der Partie 16 ist im Querschnitt kreisrund und durchquert die Öffnung 32 mittig. Die Partie 16 ist mit der Kurbelstange 10 über einen bogenförmigen Abschnitt 14 und das Endstück 18 verbunden.The central section 34 of the section 16 is circular in cross section and crossed the opening 32 in the middle. The lot 16 is with the crank rod 10 via a arcuate section 14 and the end piece 18 connected.

Wie die Fig. 3 und 4 erkennen lassen, ist der Außendurchmesser d3 in etwa so groß wie der Innendurchmesser dl der Öse, wobei der Durchmesser d2 deutlich kleiner ist als der Innendurchmesser dl. Die Länge d5 der Öffnung 32 in Richtung der Partie 16 ist deutlich kleiner als die Länge d4 des zylinderförmigen Abschnittes 34, so daß die Partie 16 in der Öffnung 32 so geneigt werden kann, daß die in Kontakt stehenden Flächen formschlüssig miteinander zusammenarbeiten, was insbesondere auch Fig. 2 zu entnehmen ist. Die Achse 24 der Partie 16 verläuft senkrecht zur Achse 12 der Kurbelstange 10. Allgemein können diese beiden Achsen 12 und 24 auch einen größeren bzw. kleineren Winkel einschließen.3 and 4, the outer diameter d3 is approximately like this Large as the inner diameter dl of the eyelet, with the diameter d2 clearly is smaller than the inner diameter dl. The length d5 of the opening 32 in the direction the lot 16 is significantly smaller than the length d4 of the cylindrical section 34, so that the lot 16 in the opening 32 can be inclined so that the in Contact standing surfaces work together positively, what 2 can be seen in particular. The axis 24 of the lot 16 runs perpendicular to the axis 12 of the crank rod 10. Generally, these two Axes 12 and 24 also include a larger or smaller angle.

Die Fig. 5 bis 7 lassen erkennen, daß der mittlere Abschnitt 34 gekröpft ist und seine Erhöhung 31' bzw. Vertiefung 31 so ausgebildet ist, daß der Abschnitt 34 in der Öffnung 32 eingehängt werden kann. Die Verdickungen 20 und 22 sind in ihrem Querschnitt ellipsenförmig, was insbesondere Fig. 5 zu entnehmen ist. Die Öffnung 25 dient für eine nicht näher dargestellte Schraube, und der Abschnitt 13 weist eine mittige Bohrung zur Aufnahme des Kurbelstange-Endstückes auf.5 to 7 show that the central portion 34 is cranked and its elevation 31 'or depression 31 is formed such that the section 34 in the opening 32 can be hung. The thickenings 20 and 22 are in their cross section is elliptical, which can be seen in particular in FIG. 5. The opening 25 serves for a screw, not shown, and the section 13 has a central bore for receiving the crank rod end piece.

Die Besonderheit der in den Fig. 8 bis 10 dargestellten Öse 30 besteht u.a. darin, daß der Innendurchmesser dl im entspannten Zustand der Öse kleiner ist als der Außendurchmesser der Verdickung 22. Der eigentliche Durchgang der Öffnung 32 ist so ausgebildet, daß er mit elastischen Schenkeln 5 und 7 versehen ist, die in Richtung der Nut 9 gebogen werden können. Der Vorteil dieser Maßnahme besteht darin, daß die Verdickung 22 durch die Öffnung 32 unter geringfügigem Widerstand hindurchgedrückt werden kann und die Kurbelstange sich von der Öse 30 nicht von selbst lösen kann. Denn dazu ist mindestens eine so große Kraft erforderlich, die zur Biegung der Schenkel 5 und 7 ausreicht. Ferner ist zu erkennen, daß zwischen den Schenkeln 5 und 7 ein Schlitz 3 ausgebildet ist, der ein problemloses Biegen der Schenkel 5, 7 ermöglicht. Die Öse 30 kann allgemein ein gespritztes und aus schlagfestem Kunststoff bestehendes Teil sein, das eine axiale Ausnehmung 11 aufweist, in die das Endstück einer Welle eines nicht näher dargestellten Getriebes einsteckbar und mittels eines Stiftes 1 verbindbar ist.The peculiarity of the eyelet 30 shown in FIGS. 8 to 10 is, inter alia, in this, that the inner diameter dl in the relaxed state of the eyelet is smaller than that Outside diameter of the thickening 22. The actual passage of the opening 32 is designed so that it is provided with elastic legs 5 and 7, which in Can be bent in the direction of the groove 9. The advantage of this measure is in that the thickening 22 through the opening 32 with slight Resistance can be pushed through and the crank rod comes off the eyelet 30 can not solve by itself. Because there is at least one such great force required, which is sufficient to bend the legs 5 and 7. Furthermore is too recognize that a slot 3 is formed between the legs 5 and 7, the allows a smooth bending of the legs 5, 7. The eyelet 30 can be general a molded and made of impact-resistant plastic part, the one has axial recess 11 into which the end piece of a shaft is not closer shown transmission can be inserted and connected by means of a pin 1.
