    • Die druckknopfartige Befestigungsvorrichtung besteht aus einem Oberteil 1 und einem Unterteil 2. Das Oberteil 1 weist eine mit einem Flansch versehene Scheibe 3 auf, die eine hohle, mittlere Hülse 4 hat. Das obere Ende der Hülse 4 ist nach innen umgebogen, um einen schmalen Schulterring 5 zu bilden. An der Innenseite der Scheibe 3 ist durch Umfalzen des äußeren Rands der Scheibe 3 eine Platte 6 befestigt, die wiederum eine hohle, mittlere Hülse 7 trägt, deren Innenraum auf die Zeichnungen bezogen sich von oben nach unten konisch verjüngt. Innerhalb der Teile 3 und 7 ist ein Greifer 8 angeordnet. Dieser ist napfförmig ausgebildet und an mehreren Stellen auf den größten Teil seiner Länge geschlitzt, so daß er an dem einen unteren Ende federnd ist. An dem federnden Ende ist der Greifer 8 mit einer hohlrunden Erweiterung ausgebildet. Das andere Ende des Greifers 8 ist mit einer mittleren Bohrung versehen. In Verbindung mit dem Greifer 8 ist eine äußere Hülse 9 vorgesehen, die eine geschlossene, mit einer mittleren Bohrung versehene Stirnwand 10 hat und mit einem äußeren Flansch 11 am gegenüber liegenden Ende ausgerüstet ist. Die Hülse 9 trägt eine als Schraubenfeder ausgeführte Feder 12, die sich gegen den Flansch 11 der Hülse 9 und gegen den Schulterring 5 der Hülse 4 abstützt.The push button-like fastening device consists of an upper part 1 and a lower part 2. The upper part 1 has a flange Disc 3, which has a hollow, middle sleeve 4. The top of the Sleeve 4 is bent inwards to form a narrow shoulder ring 5. On the inside of the disc 3 is by folding the outer edge the disc 3 is attached to a plate 6, which in turn is a hollow, central sleeve 7 bears, the interior of which referred to the drawings from above tapered at the bottom. A gripper 8 is arranged within parts 3 and 7. This is cup-shaped and in several places on the slotted most of its length so that it is at one lower end is springy. At the resilient end, the gripper 8 is hollow Extension trained. The other end of the gripper 8 has a central bore Mistake. In connection with the gripper 8, an outer sleeve 9 is provided, which is a closed end wall with a central hole 10 has and with an outer flange 11 at the opposite end is equipped. The sleeve 9 carries a spring designed as a coil spring 12, against the flange 11 of the sleeve 9 and against the shoulder ring 5th the sleeve 4 supports.

    Die Hülse 4, die Feder 12 und der Greifer 8 werden von oben her von einem Knopf 13 übergriffen, der aus einem Hülsenteil 14 mit nach außen gebogenem Flansch und einer um den Flansch herum gebördelten Kopfscheibe 15 gebildet ist. Mittels eines Niets 16 ist der Knopf 13 sowohl mit der Stirnwand 10 der Hülse 9 als auch mit der Stirnwand des Greifers 8 fest verbunden.The sleeve 4, the spring 12 and the gripper 8 are from above from one Overlapped button 13, which consists of a sleeve part 14 with an outwardly bent Flange and a head disc 15 crimped around the flange is formed. By means of a rivet 16, the button 13 is both with the front wall 10 of the sleeve 9 and also firmly connected to the end wall of the gripper 8.

    Infolge des in Richtung ihrer Längsachse ausgeübten Drucks der Feder 12 auf die Hülse 9 wird das freie Ende des federnden Greifers 8 gegen die sich nach unten konisch verjüngende Innenfläche der Hülse 7 gepreßt und das äußere Ende des federnden Greifers 8 wird infolgedessen zusammengezogen. Ein auf den Knopf 13 ausgeübter Zug bewirkt, daß die Hülse 9 und der Greifer 8 in axialer Richtung entgegen der Feder 12 bewegt werden, was ein Zurückziehen des Greifers 8 mit Bezug auf die konische Hülse 7 zur Folge hat, mit der er zusammenwirkt. Infolgedessen erhält das freie hohlrunde Ende des Greifers 8 die Möglichkeit sich auszudehnen.As a result of the pressure exerted by the spring 12 in the direction of its longitudinal axis the sleeve 9 becomes the free end of the resilient gripper 8 against itself bottom tapered inner surface of the sleeve 7 pressed and the outer The end of the resilient gripper 8 is consequently contracted. One on the button 13 exerted train causes the sleeve 9 and the gripper 8 in axial direction against the spring 12 are moved, which is a retraction of the gripper 8 with respect to the conical sleeve 7 with which he cooperates. As a result, the free hollow round end of the Gripper 8 the possibility to expand.

    Zum Oberteil 1 der Befestigungsvorrichtung gehört auch noch eine mit der Scheibe 3 zusammenwirkende Gegenscheibe 17, die dadurch auf der Hülse 7 längsbeweglich geführt ist, daß die Hülse 7 ein Außengewinde und die Gegenscheibe 17 eine Bohrung mit einem Innengewinde aufweist. Die Gegenscheibe 17 weist Angriffsflächen z. B. in Form von Stecköffnungen 18 für ein Schraubwerkzeug auf und kann damit gegen die Scheibe 3 bewegt werden, um dabei einen Stoff 19 zwischen der Scheibe 3 und der Gegenscheibe 17 einzuklemmen. Der Terminus Stoff ist im weitesten Sinne zu verstehen und soll Cabrioverdecke, Abdeckplanen ebenso einschließen wie z. B. Karosseriebleche von Fahrzeugen. Wichtig ist, daß der Stoff 19 eine Lochung 20 aufweist, damit die Gegenscheibe 17 schraubgemäß an der Hülse 7 festgelegt werden kann.The upper part 1 of the fastening device also includes one with the Disc 3 cooperating counter disc 17, which thereby on the sleeve 7th is guided longitudinally that the sleeve 7 has an external thread and the counter washer 17 has a bore with an internal thread. The counter disc 17 has attack surfaces z. B. in the form of plug openings 18 for a screwing tool and can thus be moved against the disc 3, to thereby a substance 19 between the disc 3 and the counter disc 17 to pinch. The term substance is to be understood in the broadest sense and should include convertible tops, tarpaulins as well as B. Body panels of vehicles. It is important that the fabric 19 is perforated 20, so that the counter plate 17 is screwed to the sleeve 7 can be set.

    Das Unterteil 2 der Befestigungsvorrichtung weist einen kugelförmigen, unterkehlten oder mit einer Schulter oder dgl. versehenen Kopfteil 21 auf, über den der federnde, zusammendrückbare Greifer 8 hinübergehen kann. Der Kopfteil 21 verfügt über ein Gehäuseteil 22, mit einer daran angeordneten Außenscheibe 23 und mit einem Außengewinde zum Aufschrauben einer Gegenscheibe 24, die entsprechend der Gegenscheibe 17 zum Festklemmen einer im weitesten Sinne zu verstehenden Stoffbahn 25 dient.The lower part 2 of the fastening device has a spherical, grooved or with a shoulder or the like. Provided head part 21, over which the resilient, compressible gripper 8 can pass over. Of the Head part 21 has a housing part 22, with one arranged thereon Outer washer 23 and with an external thread for screwing on a counter washer 24, corresponding to the counter plate 17 for clamping a serves in the broadest sense to understand material web 25.

    Bei der Benutzung der Befestigungsvorrichtung wird der eine Teil über den anderen unter Druck herübergeführt, und das Unterteil 2 wird durch den federnden Greifer 8 in dem Oberteil 1 festgehalten. Um die Teile wieder voneinander zu lösen, ist es notwendig, daß der Knopf 13 auswärtsgezogen wird und dies hat zur Folge, daß der federnde Greifer 8 von dem anderen Teil, der ihn umgibt, frei wird.When using the fastening device, the one part over the others passed under pressure, and the lower part 2 is supported by the resilient Gripper 8 held in the upper part 1. To get the parts back from each other to release, it is necessary that the button 13 is pulled out and this has the consequence that the resilient gripper 8 from the other part, the surrounds him, becomes free.

    Es hat sich gezeigt, daß der Schiebe- und Federmechanismus der Befestigungsvorrichtung, obgleich er sehr robust ausgeführt ist, gegen aggressive Feuchtigkeit und gegen Verschmutzen geschützt werden sollte, weil eine Korrosion und/oder ein Verschmutzen die Funktionstüchtigkeit der Befestigungsvorrichtung mit der Zeit in Frage stellen kann.It has been shown that the sliding and spring mechanism of the fastening device, although it is very robust, against aggressive Moisture and pollution should be protected because of corrosion and / or contamination of the functionality of the fastening device can question over time.

    In Fig. 1 ist hierzu eine Dichtungsscheibe 26 zwischen der Scheibe 3 und dem sich darauf abstützenden unteren Ende des Knopfs 13 vorgesehen. Die Kraft der Feder 12 gewährleistet, daß das untere Knopfende permanent gegen die Dichtungsscheibe 26 gepreßt wird, so daß durch den Spalt zwischen dem unteren Knopfende und der Scheibe 3 keine Feuchtigkeit oder Schmutz ins Oberteilinnere gelangen kann.In Fig. 1 there is a sealing washer 26 between the washer 3 and the lower end of the button 13 supported thereon. The Force of the spring 12 ensures that the lower end of the button permanently against the sealing washer 26 is pressed so that through the gap between the bottom end of the button and the disc 3 no moisture or dirt into it Can get inside the top.
