Abstract
Description
Vorrichtung zum BetätiÓen eines Autospiegels oder dergleichen Die Erfindung betrifft eine Vorrichtung zum Anlenken eines Autospiegels an die elektromotorisch angetriebene, dem Verschwenken des Trägers der Spiegelsscheibe dienenen Gewindespirldel, vorzugsweise in der Art, dass die-Spiegelscheibe mittels zweier Vorrichtungen um ein Kugel- oder Kreuzhautpgelenk klapp- und quer zur Klappachse verschwenkbar ist, wobei die Gewindespindel die Mutter zum Verstellen des Trägers trägt. Device for actuating a car mirror or the like The invention relates to a device for articulating a car mirror to the electric motor driven, the pivoting of the support of the mirror disc serving screw, preferably in such a way that the mirror pane by means of two devices around a ball or cruciform skin joint can be folded and pivoted transversely to the folding axis, wherein the threaded spindle carries the nut for adjusting the carrier.
Schweirig ist es bei allen solchen Apparaten, den Blektromotorl im bestmöglichen Liass gegen Ueberlasten zu richten. Dies bezogen auf die Beanspruchungen, auf die verlangte Dauerbelastungsfähigkeit und auf die vorgegebenen Höchstpreise. Diese Aufgabe löst das Beanspruchte bestmöglich, das dadurch gekennzeichnet -ist, dass die Mutter radialelastisch wirkt, in der Art, dass ihr Durchmesser zwecks Auskuppelns aus dem Gewinde der Gewindespindel beim Ansteigen der Stellkraft auf eine bestimmte den ordnungsgemässen Betrieb der Vorrichtung gefährdenke Grösse variabel gestaltet isto Beispielsweise kann die Mutter aus einem Thermoplast gefertigt und axparallel eingeschlitzt sein, so dass das Spreizen und auch wieder das Zurückfedern der Mutter exakt beherrchbar und vorherberechenbar ist0 Eine erfindungswesentliche Ausgestaltung sieht vor, dass das Gewinde der Mutter durch ein gewindeloses Mittelstück unterbrochen ist, in das die Schlitze zwecks Bilden von Gewindeteile tragende Zangen hineintauchenO Zeichnerisch sind Ausführungsbeispiele erläutert mit der Fig 1, die einen Autorückblickspiegel im Längsschnitt wiedergibt Die Fig. 2 und 3 stellen eine Variante im Querschnitten einander gegenäber (Mittelstellung und eine der beiden Endstellungen), während die Fig 4 und 5 eine Mutter im Axialschnitt (teils im Aufriss) und im Grundriss zeigt.It is treacherous with all such devices, the Blektromotorl im as best possible to direct against overloads. This related to the stresses on the required long-term load capacity and on the specified maximum prices. This task solves what is claimed in the best possible way, which is characterized by that the nut acts radially elastic, in such a way that its diameter for the purpose of uncoupling from the thread of the threaded spindle when the actuating force increases to a certain level The correct operation of the device jeopardizing size is made variable isto For example, the nut can be made from a thermoplastic and be slotted axparallel, so that the spreading and also the springing back again the mother is precisely controllable and predictable in advance0 An essential element of the invention Design provides that the thread of the nut through a threadless center piece is interrupted, in which the slots for the purpose of forming threaded parts carrying pliers In the drawing, exemplary embodiments are explained with FIG. 1, which shows a car rearview mirror in longitudinal section. Figs. 2 and 3 represent a Variant in cross-section facing each other (middle position and one of the two End positions), while Figs. 4 and 5 show a nut in axial section (partly in elevation) and shows in plan.
Das Gewinde 3 der Gewindespindel 2, 3 trägt die Mutter 4 zum Verstellen des Trägers i Die Mutter 4 in der Art radialelastisch, dass ihr Durchmesser zwecks Auskuppelns aus dem Gewinde 3 der Gewindespindel 2 (vgl. Endstellung bzwO Freilaufstellung in Pig 3) beim Ansteigen der Stellkraft auf eine bestimmte Grösse variabel ist0 Das Gewinde 3 der Mutter 4 ist durch ein gewindelostes Mittelstück 5 unterbrochen mithin zweigeteilt, so dass nach 2?ig 4 die Schlitze 6 zwecks Bildens von Gewindeteile traenden Zangen hineintauchen. Der Träger 1 wird mittels der Kugel 7 auf der Konsole 8 gelagert Die Teile 9, 10, sind Glieder eines Kreuzgelenkes den der Träger 1 -des Spiegels ist zweidimensional kipp- bzw. verstellbar0 Die zweite Gewindespindel istnicht veranschaulicht0 Beim Ausführungsbeispiel der Fig. 2 und 3 sind die Federdrahtschenkel 11 Mittel zum Belasten bzwO Zuruckstellen der Mutter 4 in die Transportstellung (Fig 2)o Die federartig ausgestaltete Gelenkmutter 4 öffnet und schliesst sichmithin im Betrieb im Wechsel fortwährend, solange die Gewinde spindel sich draht und die Gelenkplatte mit den an ihr angebrachten Begrensungen am Deckel aufläuft. Wird durch Fremdeinwirkung auf die Gelenkplatte (Träger 1) (oder Spiegel) ein Druck P ausgeübt, kann dieselbe nach oben oder unten gedrpckt werden , denn die Gelenkmutter überrastet dabei eine Anzahl von Gewindegängen der Gewinde spindel (ev. bis an die Begrenzung einer ddr Scheiben 12, 13) hin.The thread 3 of the threaded spindle 2, 3 carries the nut 4 for adjustment of the support i The nut 4 is radially elastic in such a way that its diameter in order to Decoupling from the thread 3 of the threaded spindle 2 (see end position or free-running position in Pig 3) is variable when the actuating force increases to a certain value0 The thread 3 of the nut 4 is through an unthreaded middle piece 5 interrupted and therefore divided into two, so that after 2? ig 4 the slots 6 for the purpose of forming Immerse in pliers that are touching threaded parts. The carrier 1 is by means of the ball 7 mounted on the console 8 The parts 9, 10 are members of a universal joint The support 1 of the mirror can be tilted or adjusted in two dimensions0 The second Screw spindle is not illustrated0 In the embodiment of Figs 3, the spring wire legs 11 are means for loading or resetting the nut 4 in the transport position (Fig. 2) o The spring-like hinged nut 4 opens and closes continuously during operation as long as the thread The wire and the joint plate with the boundaries attached to it screw themselves runs up on the lid. If the joint plate (carrier 1) (or Mirror) exerted a pressure P, the same can be pressed up or down , because the joint nut engages a number of threads of the thread spindle (possibly up to the limit of a gdr disk 12, 13).
