Description

Die Erfindung betrifft eine teleskopierbare Stellschraube für Ausstellfenster, -klappen, -dächer u. dgl.The invention relates to a telescopic screw for hinged windows, flaps, roofs and. the like

Derartige teleskopierbare Stellschrauben sind für die verschiedensten Zwecke bekannt und sollen bei möglichst geringer Länge im zusammengeschraubten Zustand einen möglichst großen Ausstellbereich ermöglichen. Bei einer bekannten Stellschraube dieser Art ist ein Gewindezapfen an seinem einen Ende mit dem Ausstellfenster u. dgl. drehbar befestigt und trägt an seinem anderen Ende einen Drehknopf. Der Gewindezapfen ist durch eine Gewindebuchse hindurchgeführt, welche mittels eines Außengewindes in eine entsprechende drehfeste und axial verschiebefeste Gewindebohrung eingreift. In vollständig zurückgeschraubtem Zustand liegt die Gewindebuchse mit einem Anschlag an der Gewindebohrung an und der Gewindezapfen liegt mit einem Anschlag an der Gewindebuchse an. Um das Ausstellfenster u. dgl. auszustellen, wird der Drehknopf betätigt, so daß zunächst der Gewindezapfen durch die Gewindebuchse hindurchgeschraubt wird, bis der Drehknopf zum Anschlag an die Gewindebuchse kommt. Nunmehr wird die Gewindebuchse zusammen mit dem Gewindezapfen weitergedreht und schraubt sich in der Gewindebohrung nach vorwärts, so daß auf diese Weise ein Ausstellweg erreicht wird, der aus der Summe der Wege des Gewindezapfens in der Gewindebuchse und der Gewindebuchse in der Gewindebohrung besteht.Such telescopic set screws are known for a wide variety of purposes and are intended to enable the largest possible opening area with the smallest possible length when screwed together. In a known screw of this type, a threaded pin at one end with the opening window u. The like. rotatably attached and carries a knob at its other end. The threaded pin is guided through a threaded bushing which engages in a corresponding non-rotatable and axially displaceable fixed bore by means of an external thread. In the fully screwed-back state, the threaded bush lies against the threaded bore with a stop and the threaded pin lies against the threaded bush with a stop. To the opening window u. Issue the like. The rotary knob is actuated so that the threaded pin is first screwed through the threaded bushing until the rotary knob comes to a stop against the threaded bushing. Now the threaded bush rotated further together with the threaded pin and screwed forward in the threaded hole, so that in this way an opening path is achieved which consists of the sum of the paths of the threaded pin in the threaded bushing and the threaded bushing in the threaded bore.

Bei dieser bekannten Stellschraube ist nachteilig, daß die Gewinde nach außen vollständig offen und ungeschützt sind und falls sie gefettet sind, zu Verschmutzungen beim Betätigen Anlaß geben können. Weiterhin ragt der Drehknopf im vollständig zurückgeschraubten Zustand um den Ausstellweg in den Betätigungsraum zurück, was bei der Verwendung in Kraftfahrzeugen aus Sicherheitsgründen nicht zulässig ist. Nachteilig ist weiterhin,'daß die Betätigung der Stellschraube verhältnismäßig langsam vor sich geht, da der Ausstellweg gleich dem von der Schraube zurückzulegenden Weg ist. Zwar könnte die Betätigungs-geschwindigkeit erhöht werden, indem zum Beispiel der Gewindezapfen und die Gewindebuchse mit einem Steilgewinde versehen werden; jedoch sind Steilgewinde im allgemeinen nicht selbsthemmend, so daß eine zusätzliche Sicherung gegen Verstellen vorgesehen werden müßte.This known adjusting screw has the disadvantage that the threads are completely open to the outside and unprotected and, if they are greased, can give rise to contamination when actuated. Furthermore, the rotary knob protrudes in the fully screwed-back state by the opening distance into the actuation space, which is not permitted for safety reasons when used in motor vehicles. A further disadvantage is that the actuation of the adjusting screw is relatively slow, since the opening distance is the same as the distance to be covered by the screw. Although the Betätigun could g s speed can be increased by, for example, be fitted to the threaded pin and the threaded bushing with a coarse-pitch thread; however, high helix threads are generally not self-locking, so that additional protection against adjustment would have to be provided.

Der Erfindung liegt die Aufgabe zugrunde, eine teleskopierbare Stellschraube zu schaffen, die einfach in der Herstellung ist, keine offenliegenden Gewinde oder Gewindeteile aufweist und trotz Selbsthemmung mit der doppelten Geschwindigkeit gegenüber einer herkömmlichen teleskopierbaren Stellschraube betätigbar ist. Weiterhin soll die erfindungsgemäße Stellschraube so flach bauen, daß keine die Sicherheit beeinträchtigenden-Teile in den Fahrgastraum eines Fahrzeuges hineinragen, und zwar unabhängig davon, ob das Ausstellfenster u. dgl. geöffnet oder geschlossen ist.The invention has for its object to provide a telescopic screw that is easy to manufacture, has no exposed threads or threaded parts and can be operated despite the self-locking at twice the speed of a conventional telescopic screw. Furthermore, the adjusting screw according to the invention should be so flat that no safety-impairing parts protrude into the passenger compartment of a vehicle, regardless of whether the opening window u. Like. Is open or closed.

Gelöst wird diese Aufgabe durch die Merkmale des Hauptanspruches. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Ansprüchen.This task is solved by the features of the main claim. Further advantageous embodiments of the invention result from the following claims.

Bei der erfindungsgemäßen Stellschraube wird durch die gegenläufigen Gewinde erreicht, daß durch das Drehen der drehbaren Buchse gleichzeitig diese Buchse in der feststehenden Buchse und der Gewindezapfen in der drehbaren Buchse gleichsinnig verstellt werden. Die Bewegung der drehbaren Buchse und des Gewindezapfens addieren sich dadurch, so daß der Gewindezapfen im Verhältnis zur feststehenden Buchse den doppelten Weg gegenüber der drehbaren Buchse zurücklegt. Aufgrund der aus dieser Anordnung resultierenden doppelten Bewegungsgeschwindigkeit des Gewindezapfens gegenüber der drehbaren Buchse bleibt die erfindungsgemäße teleskopierbare Stellschraube selbsthemmend, da sowohl für den Gewindezapfen als auch für die drehbare Buchse eingängige Gewinde verwendbar sind. Die feststehende Buchse kann vorteilhafterweise einstückig mit der Halterung ausgebildet sein, wobei diese Halterung etwa mittig an der feststehenden Buchse angreift. Da somit nur etwa die Hälfte der Länge der feststehenden Buchse aus der Halterung herausragt, kann diese in einer Mulde der Halterung angeordnet werden und zusätzlich durch den großflächig ausgebildeten Drehknopf abgedeckt werden. Da sich der Drehknopf in axialer Richtung nicht bewegt, ergibt sich insgesamt eine großflächige Ausbildung der Verstellvorrichtung für das Ausstellfenster u. dgl., welche allen Sicherheitsanforderungen gerecht wird. Die Einzelteile der erfindungsgemäßen Stellschraube lassen sich als Spritzgußteile aus Kunststoff und/oder Metall herstellen und sind daher besonders für hohe Stückzahlen geeignet.In the adjusting screw according to the invention, the opposite threads achieve that, by rotating the rotatable bush, this bush in the fixed bush and the threaded pin in the rotatable bush are simultaneously adjusted in the same direction. The movement of the rotatable bush and the threaded pin add up, so that the threaded pin travels twice the distance in relation to the fixed bush compared to the rotatable bush. Due to the double movement speed of the threaded pin compared to the rotatable bushing resulting from this arrangement, the telescopic adjusting screw according to the invention remains self-locking, since single-threaded threads can be used both for the threaded pin and for the rotatable bushing. The fixed socket can advantageously be formed in one piece with the holder, this holder engaging approximately centrally on the fixed socket. Since only about half the length of the fixed socket protrudes from the holder, it can be arranged in a recess in the holder and additionally covered by the large-area rotary knob. Since the rotary knob does not move in the axial direction, the adjustment device for the opening window and the like are formed over a large area. Like., Which meets all security requirements. The individual parts of the set screw according to the invention can be produced as injection molded parts made of plastic and / or metal and are therefore particularly suitable for large quantities.

  • Fig. 1 shows a longitudinal section through the screw and
  • FIG. 2 shows a cross section along the line I - I in FIG. 1.

In der Zeichnung ist die Stellschraube im Dach eines Personenkraftwagens dargestellt und dient zur Betätigung eines Ausstellfensters. Am Dach 2 sind ein oberes Rahmenprofil 4 und ein unteres Rahmenprofil 6 mittels Schrauben 8 unter Zwischenfügung eines Dichtprofils 10 miteinander verschraubt. In eine Rinne des oberen Rahmenprofils 4 ist ein weiteres Dichtprofil 12 eingelegt, welches die Abdichtung gegenüber dem Ausstellfenster bewirkt. Ein Dachhimmel 14 ist mit dem unteren Rahmenprofil 6 verklebt. Eine Halterung 16 ist mittels einer Klemmleiste 17 und Schrauben 8 gegen das obere Rahmenprofil 4 geschraubt und weist eine einstückig hergestellte, feststehende Buchse 18 auf. Die Halterung 16 greift etwa mittig an der feststehenden Buchse 18 an. Die feststehende Buchse 18 ist mit einem Innengewinde 20, das als Trapezgewinde ausgebildet ist, versehen. Das aus der Halterung 16 herausragende Ende der feststehenden Buchse 18 ist mit einem umlaufenden radial hervorstehenden Bund 22 versehen. In die feststehende Buchse 18 ist eine drehbare Buchse 24 mit einem Außengewinde 26 eingeschraubt. Die drehbare Buchse 24 weist ein Innengewinde 28 auf sowie in der Wandung zwischen dem Außengewinde 26 und dem Innengewinde 28 eine zylindrische Ausnehmung 30, die mit einer Innenverzahnung 32 versehen ist. Das eine Ende der drehbaren Buchse 24 wird durch einen Anschlag 34 in Form eines radial nach innen gerichteten Überständes begrenzt. In die drehbare Buchse 24 ist ein Gewindezapfen 36 mit einem Außengewinde 38 eingeschraubt. Die miteinander in Eingriff stehenden Gewinde 20, 26 der feststehenden Buchse 18 und der drehbaren Buchse 24 sowie die miteinander in Eingriff stehenden Gewinde 28, 38 der drehbaren Buchse 24 und des Gewindezapfens 36 sind gegenläufig ausgebildet, so daß sich der Gewindezapfen 36,der drehfest gelagert ist, gleichsinnig, aber mit doppelter Geschwindigkeit gegenüber der drehbaren Buchse 24 in axialer Richtung bewegt. Der Gewindezapfen 36 ist an einer Gabel 4o mittels eines Gelenkzapfens 42 angelenkt. Die Gabel 4) ist mittels einer Schraube 46 an einer Hutmutter 44 befestigt, welche durch eine Bohrung in einer Scheibe 48 des Ausstellfensters hindurchgreift. Ein Drehknopf 5o ist mit einem zylindrischen Fortsatz 52 und nach innen gerichteten Rastnasen 54 versehen, welche hinter den Bund 22 an der feststehenden Buchse 18 greifen und so eine drehbare, jedoch axial verschiebefeste Lagerung des Drehknopfes 5o gewährleisten. Ein weiterer zylindrischer Fortsatz 56 mit einer Außenverzahnung 58 greift in die Ausnehmung 3o mit der Innenverzahnung 32 ein, wodurch eine Drehbewegung des Drehknopfes 50 auf die drehbare Buchse 24 übertragen wird und diese sich gleichzeitig in axialer Richtung bewegen kann.In the drawing, the set screw in the roof of a passenger car is shown and is used to actuate an opening window. On the roof 2, an upper frame profile 4 and a lower frame profile 6 are screwed together by means of screws 8 with the interposition of a sealing profile 10. In a groove of the upper frame profile 4, a further sealing profile 12 is inserted, which causes the seal against the opening window. A headliner 14 is glued to the lower frame profile 6. A bracket 16 is screwed against the upper frame profile 4 by means of a clamping strip 17 and screws 8 and has a fixed bushing 18 which is produced in one piece. The bracket 16 engages approximately centrally on the fixed bushing 18. The fixed bushing 18 is provided with an internal thread 20 which is designed as a trapezoidal thread. The end of the fixed bushing 18 protruding from the holder 16 is provided with a circumferential radially projecting collar 22. A rotatable bushing 24 with an external thread 26 is screwed into the fixed bushing 18. The rotatable bushing 24 has an internal thread 28 and in the wall between the external thread 26 and the internal thread 28 a cylindrical recess 30 which is provided with an internal toothing 32. One end of the rotatable bushing 24 is delimited by a stop 34 in the form of a radially inward projection. A threaded pin 36 with an external thread 38 is screwed into the rotatable bushing 24. The one engaged standing threads 20, 26 of the fixed bushing 18 and the rotatable bushing 24 and the mutually engaging threads 28, 38 of the rotatable bushing 24 and the threaded pin 36 are designed in opposite directions, so that the threaded pin 36, which is non-rotatably mounted, is in the same direction, but moved at twice the speed in relation to the rotatable bushing 24 in the axial direction. The threaded pin 36 is articulated on a fork 4o by means of a joint pin 42. The fork 4) is fastened by means of a screw 46 to a cap nut 44 which extends through a hole in a washer 48 of the opening window. A rotary knob 5o is provided with a cylindrical extension 52 and inwardly directed latching lugs 54 which engage behind the collar 22 on the fixed bushing 18 and thus ensure a rotatable but axially displaceable mounting of the rotary knob 5o. Another cylindrical extension 56 with an external toothing 58 engages in the recess 30 with the internal toothing 32, as a result of which a rotary movement of the rotary knob 50 is transmitted to the rotatable bushing 24 and the latter can simultaneously move in the axial direction.

Aus dem vorstehenden ergibt sich, daß trotz einer insgesamt flachen Ausbildung der erfindunosgermäßen Stellschraube ein großer Ausstellweg erreichbar ist, ohne daß von außen zugängliche Teile der Stellschraube eine Axialbewegung durchführen. Der großflächige Drehknopf 50, der in einer Mulde der Halterung 16 liegt, kann zumindest teilweise aus einem stoßabsorbierenden Material hergestellt werden, so daß eine zusätzliche Verminderung der Verletzungsgefahr erreichbar ist.It follows from the above that, in spite of an overall flat design of the adjusting screw according to the invention, a large opening path can be reached without parts of the adjusting screw accessible from the outside performing an axial movement. The large-area rotary knob 50, which lies in a recess of the holder 16, can be made at least partially from a shock-absorbing material, so that an additional reduction in the risk of injury can be achieved.

Um die Drehbewegung vom Drehknopf 50 auf die drehbare Buchse 24 zu übertragen, können auch andere Mittel als die in der Zeichnung dargestellten verwendet werden. So ist es zum Beispiel möglich, am Drehknopf einen oder mehrere außermittig angeordnete Mitnehmerstifte vorzusehen, die in eine entsprechende Ausnehmung der drehbaren Buchse 24 eingreifen. Diese Mitnehmerstifte müssen selbstverständlich so lang sein, daß auch bei größtmöglicher Ausstellung noch ein Eingriff mit der drehbaren Buchse 24 gewährleistet ist. Dasselbe gilt auch für den zylindrischen Fortsatz 56 im dargesteltten Ausführungsbeispiel, dessen axiale Länge so groß ist, daß in den Extremstellungen eine einwandfreie Drehübertragung gewährleistet ist. Da die gewählten Trapezgewinde robust mit großem Querschnitt ausgebildet werden können, genügt es, an der drehbaren Buchse 24 und am Gewindezapfen 36 als Außengewinde 26 bzw. 38 ein bis maximal zwei Gänge vorzusehen. Auf diese Weise wird die Betätigung der Stellschraube besonders leichtgängig.In order to transmit the rotary movement from the rotary knob 50 to the rotatable bushing 24, means other than those shown in the drawing can also be used. For example, it is possible to provide one or more eccentrically arranged driving pins on the rotary knob which engage in a corresponding recess in the rotatable bushing 24. These driver pins must of course be so long that even with the largest possible exhibition an engagement with the rotatable bush 24 is still guaranteed. The same also applies to the cylindrical extension 56 in the illustrated embodiment, the axial length of which is so great that a perfect transmission of rotation is ensured in the extreme positions. Since the selected trapezoidal threads can be made robust with a large cross-section, it is sufficient to provide one to a maximum of two gears on the rotatable bushing 24 and on the threaded pin 36 as external thread 26 or 38. In this way, the actuation of the set screw becomes particularly easy.
