Abstract

The joint is partic for precision toy models or components such as vehicle rear view mirrors, and is produced in a single operation as one component. It is made from plastic and the three connecting members (axially moving inner ring, intermediate ring (2) and coupling ring) are held together b two flexible supports (4, 5) that are parallel to the axis of the inner ring. The coupling ring has two spigots (6) that meet at right angles on the axis of the inner ring. There are pivot limiting stops for the flexible support (4) between the intermediate ring (2) and the coupling ring.

Description

Kreuzgelenk. Universal joint.

Die Erfindung betrifft ein Kreuzgelenk für feinmechanische Geräte, z.B. für Spielzeuge, für Autorückspiegel o. dergl...The invention relates to a universal joint for precision mechanical devices, e.g. for toys, for car rearview mirrors or the like ...

3ei Gegenstand nach DBGM 7 433 547 wird ein normales Zapfengelenk verwendet0 Solche Gelenke sind dann oft kostspielig, wenn von einem. ralativ leistungsstarken Elektromotor Konsolen angetrieben erden können, deren Verstellbarkeitsbedarf klein ist. Deshalb war es das Ziel der Erfindung, ein optimal billiges Kreuzgelenk anbieten zu können, welches in einem einzigen rbeitsgang aus einem elastischen Material organischer herkunft spritzbar ist0 Die Lösung des Erfindungszieles ist erfindungsgemäss dadurch gekennzeichnet, dass seine drei gelenkig zusarmenhängenden Glieder (axial verschiebbarer Innenring, Zwischenring, Kuppelring) durch je zwei sich parallel zur Achse (A) des Innenringes erstreckende Riegellager verbunden sind, Diese bauart lässt es zu, dass das Spritzteil in einem einfachen @ erkzeug hergestellt werden kann, Sasbesondere dann, wenn der Kuppelring zwei Kuppelzapfen aufweist, deren gemeinsame Zapfenachse die Achse des Innenringes im rechten iinkWl kreuzt und wenn die Biegelager zwischen Zwischenring und Kuppelring in Schwenkbegrenzungsanschläge auslaufen.The object according to DBGM 7 433 547 is a normal pivot joint Such joints are often costly if used by one. relatively powerful Electric motor consoles driven can be grounded, the need for adjustability is small is. Therefore, the aim of the invention was to offer an optimally cheap universal joint to be able to do this in a single operation from an elastic material organic origin can be injected characterized in that its three articulated limbs (axially displaceable Inner ring, intermediate ring, coupling ring) by two each parallel to the axis (A) of the Inner ring extending bolt bearings are connected, this design allows that the molded part can be produced in a simple tool, in particular when the coupling ring has two coupling pins, their common pin axis the axis of the inner ring in the right iinkWl crosses and if the bending bearings between Intermediate ring and coupling ring run out in swivel limit stops.

Der Erfindungsgegenstand ist zudem optin1al robust, so dass er von Kräften, die von der Konsole aus in Richtung zwa Antriebsmotor hin normalerweise nicht beschädigbar ist.The subject matter of the invention is also optin1al robust, so that it is of Forces from the console in the direction of the drive motor normally cannot be damaged.

Die Zeichnung zeigt ein Ausführungsbeispiel gemäss Fig 1 mittels einer Seitenansicht, gemäss Fig 2 mittels eines Aufrissen und gemäss Fig 3 mittels des Grundrisses. Eine Variante zeigen die Fig 4 und 5 in Seitenansicht und Aufriss.The drawing shows an embodiment according to FIG. 1 by means of a Side view, according to FIG. 2 by means of an elevation and according to FIG. 3 by means of the Floor plan. A variant is shown in FIGS. 4 and 5 in side view and elevation.

Die Konsole, die zoBo den Autorückspiegel trägt, ist nicht dargestellt, doch kann an sie sich els an die Zapfen 6 angeklemmt leicht vorstellen0 Das ganze Gelenk ist (die Gewinde spindel 7 natürlich ausgenommen) aus einem guzmielastischen Kunststoff einstückig gefertigt, so dass seine drei gelenkig zusammenhöngenden Glieder, nämlich der axial verschiebbare Innenring 1, der Zwischenring 2 und der Kuppelring 3 durch je zwei sich parallel zur Achse A des Innenringes 1 erstreckende Biegelager 4, 5 verbunden, Der Kuppelring 3 trägt zwei Kuppelzapfen 6, deren gemeinsame Zapfenachse die Achse des Innenringes 1 im rechten-Winkel kreuzt, Die Biegelager 4 zwischen Zwischenring 2 und Kuppelring 3 laufen in Schwenkbegrenzungsanschläge, so dass ein Ueberlasten der Gelenke 4, 5 deshalb nie stattfinden kann, weil Anschläge als extrem lange Hebelarme ausgelegt sind,The console that zoBo carries the car rearview mirror is not shown, but it can easily be imagined as being clamped to the tenons 60 The whole Joint is (the threaded spindle 7 excepted, of course) from a guzmielastic Plastic manufactured in one piece, so that its three articulated links, namely the axially displaceable inner ring 1, the intermediate ring 2 and the coupling ring 3 by two flexible bearings each extending parallel to the axis A of the inner ring 1 4, 5 connected, the coupling ring 3 carries two coupling pins 6, their common pin axis the axis of the inner ring 1 crosses at right angles, the flexure bearings 4 between Intermediate ring 2 and coupling ring 3 run in pivot limit stops, so that a Overloading of the joints 4, 5 can never take place because attacks are extreme long lever arms are designed,
