Eine derartige druckknopfartige Befestigungsvorrichtung wird von der Anmelderin seit vielen Jahren im großen Umfang vertrieben. Die Befestigungsvorrichtung ist besonders dann hervorragend geeignet, wenn ein schnell- und leichtlösbarer, jedoch belastungssicherer Verschluß gewünscht wird, beispielsweise für abnehmbare Tragbügel an Phonogeräten, als Deckelverschluß für Behälter oder zur sicheren Befestigung von Maschinenverkleidungen und Cabrioverdecken. Die Befestigungsvorrichtung eignet sich besonders für häufig zu lösende Verbindungen an Gebrauchsgegenständen, wie zur sicheren Befestigung von Planen, Verdecken und anderen Abdeckungen.Such a push button-like fastening device has been sold on a large scale by the applicant for many years. The fastening device is particularly well suited if, for example, a fast and easily releasable, but load-resistant closure is desired For detachable mounting brackets on phono devices, as a lid lock for containers or for the secure attachment of machine panels and convertible tops. The fastening device is particularly suitable for connections to commodities that are to be loosened frequently, such as for securely fastening tarpaulins, covers and other covers.

Eine druckknopfartige Befestigungsvorrichtung der gattungsgemäßen Art ist zudem aus der DE 4 08 806 bekannt.A push-button-like fastening device of the generic type is also known from DE 4 08 806.

Bisher ist man davon ausgegangen, daß der Mechanismus der Befestigungsvorrichtung aufgrund seiner weitgehenden Einkapselung nicht störanfällig ist. Die Umweltbelastungen nehmen jedoch ständig zu, so daß auch druckknopfartige Befestigungsvorrichtungen der in Rede stehenden Art durch korrosive Einflüsse belastet werden, so daß deren Störunanfälligkeit auf Dauer nicht mehr zu gewährleisten ist.So far it has been assumed that the mechanism of the fastening device is not susceptible to failure due to its extensive encapsulation. However, the environmental pollution is constantly increasing, so that even snap fasteners of the type in question are loaded by corrosive influences, so that their susceptibility to interference can no longer be guaranteed in the long run.

Der Erfindung liegt daher die Aufgabe zugrunde, eine druckknopfartige Befestigungsvorrichtung der eingangs genannten Art hinsichtlich der Funktionstüchtigkeit über längere Zeiträume hinweg zu verbessern.The invention is therefore based on the object of improving a push-button-like fastening device of the type mentioned in terms of functionality over longer periods of time.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß das Oberteil der Befestigungsvorrichtung durch Abdichtungsmittel gegen ein Eindringen von Feuchtigkeit und/oder Schmutz ins Oberteilinnere geschützt ist.To achieve this object, the invention provides that the upper part of the fastening device is protected by sealing means against the ingress of moisture and / or dirt into the upper part of the upper part.

Die erfindungsgemäß vorgesehenen Abdichtungsmittel sollen also eine derart weitgehende Abkapselung des im Oberteilinnern befindlichen Befestigungsmechanismusses bewirken, daß ein Eindringen von Feuchtigkeit oder Schmutzpartikeln praktisch ausgeschlossen wird.The sealing means provided according to the invention are intended to encapsulate the fastening mechanism located inside the upper part to such an extent that the penetration of moisture or dirt particles is practically excluded.

Die Erfindung läßt sich mit unterschiedlichen Mitteln einfach und kostengünstig verwirklichen. Gemäß einer Ausführungsform weist das Hauptteil eine Hülse auf, deren eines Ende in eine Scheiben übergeht, auf dem der Knopf mit einem unteren Ende abgestützt ist, wobei zwischen der Scheibe und dem unteren Knopfende eine Dichtungsscheibe als Abdichtungsmittel angeordnet ist. Durch diese Maßnahme ist der gegen ein Eindringen von Feuchtigkeit oder Schmutz bisher gefährdeste Bereich des Oberteils der Befestigungsvorrichtung geschützt.The invention can be implemented simply and inexpensively by various means. According to one embodiment, the main part has a sleeve, one end of which merges into a disk on which the button is supported with a lower end, a sealing disk being arranged as a sealing means between the disk and the lower button end. This measure prevents moisture penetration or dirt previously protected area of the upper part of the fastening device.

Bevorzugterweise ist über dem kugelförmigen Kopfteil des Unterteils zusätzlich eine Dichtungsscheibe geknöpft, die von der unteren Begrenzungsfläche der ringförmigen Hülse des Oberteils beim Zusammenfügen von Oberteil und Unterteil beaufschlagt wird. Damit können auch durch den Verbindungsbereich zwischen Ober- und Unterteil der Befestigungsvorrichtung keine korrosiven Stoffe ohne weiteres mehr ins Oberteilinnere gelangen.Preferably, a sealing washer is additionally buttoned over the spherical head part of the lower part, which is acted upon by the lower boundary surface of the annular sleeve of the upper part when the upper part and lower part are joined together. This means that no corrosive substances can easily get into the interior of the upper part through the connection area between the upper and lower part of the fastening device.

Eine andere, die Abdichtung des Oberteils betreffende, Ausführungsform sieht vor, daß der Knopf einen Hülsenteil mit einer flanschartigen Abwinklung an einem Ende aufweist, um die herum eine Kopfscheibe gefalzt ist und daß der Hülsenteil einen aufgeschobenen Dichtungsschlauch trägt, dessen eines Ende die Kopfscheibe gegenüber der flanschartigen Abwinklung abdichtet und deren anderes Ende auf der Scheibe des Hauptteils dichtend abgestützt ist. Eine Weiterbildung dieser Maßnahme kann darin bestehen, daß der Dichtschlauch als Formkörper ausgebildet ist, der an einem Ende eine sich sowohl an der flanschartigen Abwinklung als auch um die darum gefalzte Kopfscheibe abstützende Verdickung und am anderen Ende eine Ringnut in einem verdickten Bereich aufweist, in die der Hülsenteil mit dem unteren Endbereich eingreift.Another embodiment relating to the sealing of the upper part provides that the button has a sleeve part with a flange-like bend at one end, around which a head washer is folded, and that the sleeve part carries a pushed-on sealing tube, one end of which is opposite the head washer seals flange-like bend and the other end is supported sealingly on the disc of the main part. A further development of this measure can consist in the fact that the sealing hose is designed as a shaped body which has a thickening which is supported both at the flange-like angled portion and around the folded top washer and at the other end has an annular groove in a thickened area into which the sleeve part engages with the lower end region.

Eine noch weitergehende Abkapselung des Oberteilinnern läßt sich dadurch erreichen, daß der Knopf von einer Kappe aus weichelastischem Gummi- oder Kunststoffmaterial umgeben ist, deren freier Endbereich auf der Scheibe des Hauptteils abgestützt ist. Die Kappe aus weichelastischem Gummi- oder Kunststoffmaterial kann dabei einerseits auf der Scheibe des Hauptteils abgestützt sein und andererseits auch den Umfangsrand der Scheibe umgreifen. Bevorzugterweise ist die Kappe im Umgreifungsbereich der Scheibe faltenbalgartig ausgebildet, so daß die Abdichtung auch bei einer etwaigen Verkantung zwischen dem Oberteil und Unterteil der Befestigungsvorrichtung wirksam ist.A further encapsulation of the inside of the upper part can be achieved in that the button is surrounded by a cap made of flexible rubber or plastic material, the free end region of which is supported on the disk of the main part. The cap made of soft elastic rubber or plastic material can be supported on the one hand on the disc of the main part and on the other hand also encompass the peripheral edge of the disc. The cap is preferably designed to be bellows-like in the area around the disk, so that the seal is also effective in the event of any canting between the upper part and lower part of the fastening device.

Schließlich kann vorgesehen sein, daß die Gegenscheibe des Unterteils mit einer Dichtmanschette versehen ist, die eine an der unteren Begrenzungsfläche der ringförmigen Hülse des Oberteils abstützbare Dichtlippe aufweist.Finally, it can be provided that the counter plate of the lower part is provided with a sealing sleeve, one on the lower Boundary surface of the annular sleeve of the upper part has a supportable sealing lip.

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 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 Stirn-wand 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 3 with a flange, which has a hollow, middle sleeve 4. The upper end of the sleeve 4 is bent inwards to form a narrow shoulder ring 5. On the inside of the disc 3, a plate 6 is fastened by folding over the outer edge of the disc 3, which in turn carries a hollow, middle sleeve 7, the interior of which tapers conically from top to bottom in the drawings. A gripper 8 is arranged within parts 3 and 7. This is cup-shaped and slotted in several places over most of its length, so that it is resilient at one lower end. At the resilient end, the gripper 8 is formed with a hollow, round extension. The end of the gripper 8 is provided with a central hole. In connection with the gripper 8, an outer sleeve 9 is provided which has a closed end wall provided with a central bore 10 and is equipped with an outer flange 11 at the opposite end. The sleeve 9 carries a spring 12 designed as a helical spring, which is supported against the flange 11 of the sleeve 9 and against the shoulder ring 5 of the sleeve 4.

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 overlapped from above by a button 13 which is formed from a sleeve part 14 with an outwardly bent flange and a head disc 15 crimped around the flange. By means of a rivet 16, the button 13 is firmly connected both to the end wall 10 of the sleeve 9 and 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 of the spring 12 on the sleeve 9 in the direction of its longitudinal axis, the free end of the resilient gripper 8 is pressed against the downwardly conically tapering inner surface of the sleeve 7 and the outer end of the resilient gripper 8 is consequently contracted. A pull on the button 13 causes the sleeve 9 and the gripper 8 to move axially against the spring 12, causing the gripper 8 to retract with respect to the conical sleeve 7 with which it cooperates. As a result, the free hollow end of the gripper 8 is given the opportunity 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 a counter disk 17 which cooperates with the disk 3 and which is guided on the sleeve 7 in such a way that the sleeve 7 has an external thread and the counter disk 17 has a bore with an internal thread. The counter disc 17 has contact surfaces z. B. in the form of plug-in openings 18 for a screwing tool and can thus be moved against the disc 3 to thereby clamp a substance 19 between the disc 3 and the counter disc 17. The term fabric is to be understood in the broadest sense and is intended to include convertible tops, tarpaulins as well as e.g. B. body panels of vehicles. It is important that the fabric 19 has a perforation 20 so that the counter plate 17 can be screwed to the sleeve 7.

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 head part 21 or one provided with a shoulder or the like which the resilient, compressible gripper 8 can pass over. The head part 21 has a housing part 22, with an outer disk 23 arranged thereon and with an external thread for screwing on a counter disk 24, which, in accordance with the counter disk 17, is used for clamping a material web 25 which is to be understood in the broadest sense.

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, one part is passed over the other under pressure, and the lower part 2 is held by the resilient gripper 8 in the upper part 1. In order to detach the parts from one another again, it is necessary for the button 13 to be pulled outwards and this has the consequence that the resilient gripper 8 is released from the other part which surrounds it.

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 found that the sliding and spring mechanism of the fastening device, although of very robust design, should be protected against aggressive moisture and against soiling, because corrosion and / or soiling can question the functionality of the fastening device 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, a sealing washer 26 is provided 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 is permanently pressed against the sealing washer 26, so that no moisture or dirt can get into the interior of the upper part through the gap between the lower end of the button and the washer 3.

In Fig. 1 ist weiterhin gezeigt, daß im Verbindungsbereich zwischen dem Oberteil 1 und dem Unterteil 2 Abdichtungsmittel vorgesehen sind, und zwar hier in Form einer Dichtungsscheibe 27, die über den Kopfteil 21 des Unterteils 2 geknöpft ist. Beim Zusammenfügen von Oberteil 1 und Unterteil 2 wird die Dichtungsscheibe 27 von der unteren Begrenzungsfläche der als ringförmiger Körper ausgebildeten Hülse 7 beaufschlagt.In Fig. 1 it is also shown that sealing means are provided in the connection area between the upper part 1 and the lower part 2, here in the form of a sealing washer 27, which is buttoned over the head part 21 of the lower part 2. When the upper part 1 and lower part 2 are joined together, the sealing disk 27 is acted upon by the lower boundary surface of the sleeve 7, which is designed as an annular body.

In Fig. 2 besteht das Abdichtungsmittel aus einem Dichtungsschlauch 28, der auf den Hülsenteil 14 des Knopfs 13 aufgeschoben ist. Ein Ende des Dichtungsschlauchs 28 dichtet den Scheibenteil 15 gegenüber der flanschartigen Abwinklung ab, während das andere Ende auf dem Flansch bzw. der Scheibe 3 abgestützt ist und hier eine Dichtfunktion übernimmt.In Fig. 2, the sealing means consists of a sealing tube 28 which is pushed onto the sleeve part 14 of the button 13. One end of the sealing tube 28 seals the disc part 15 with respect to the flange-like one Angling from while the other end is supported on the flange or the disc 3 and here takes over a sealing function.

Der Dichtungsschlauch 28 nach Fig. 2 ist in Fig. 3 als Formkörper 29 ausgebildet, der an einem oberen Ende eine sich sowohl an der flanschartigen Abwinkelung als auch an der darum gefalzten Kopfscheibe 15 des Knopfs 13 abstützende Verdickung aufweist. Am anderen unteren Ende weist der Formkörper 29 eine Verdickung mit einer Ringnut 30 auf, in die der Hülsenteil 14 mit dem unteren Endbereich eingreift.The sealing tube 28 according to FIG. 2 is formed in FIG. 3 as a molded body 29, which has at its upper end a thickening which is supported both on the flange-like bend and on the head disc 15 of the button 13 folded around it. At the other lower end, the molded body 29 has a thickening with an annular groove 30, in which the sleeve part 14 engages with the lower end region.

Fig. 4 zeigt in bezug auf das Oberteil 1 der Befestigungsvorrichtung eine den Knopf 13 umgebende Kappe 31, die ebenso wie die Teile 26 bis 29 aus einem weichelastischem Gummi- oder Kunststoffmaterial besteht. Der freie Endbereich der Kappe 31 ist auf der Scheibe 3 des Oberteils 1 abgestützt. Durch die Kappe 31 sind etwaige Spalte zwischen dem Knopf 13 und der Scheibe 3 ebenso abgedichtet wie Spalte zwischen dem Hülsenteil 14 und dem Scheibenteil 15 des Knopfes 13 und auch etwaige Spalte im Bereich des Niets 26.FIG. 4 shows, with respect to the upper part 1 of the fastening device, a cap 31 surrounding the button 13, which, like the parts 26 to 29, consists of a flexible rubber or plastic material. The free end region of the cap 31 is supported on the disk 3 of the upper part 1. The cap 31 seals any gaps between the button 13 and the washer 3 as well as gaps between the sleeve part 14 and the washer part 15 of the button 13 and also any gaps in the area of the rivet 26.

Fig. 4 zeigt zudem in bezug auf das Unterteil 2 eine Abdichtung, gemäß der die Gegenscheibe 24 des Unterteils 2 mit einer Dichtmanschette 32 versehen ist, die eine an der unteren Begrenzungsfläche der Hülse 7 des Oberteils 1 abstützbare Dichtlippe aufweist.4 also shows a seal with respect to the lower part 2, according to which the counter washer 24 of the lower part 2 is provided with a sealing collar 32 which has a sealing lip which can be supported on the lower boundary surface of the sleeve 7 of the upper part 1.

Fig. 5 schließlich zeigt für das Oberteil 1 der Befestigungsvorrichtung ein Abdichtungsmittel, welches aus einer sowohl den Knopf 13 als auch den Umfangsrand der Scheibe 3 umgreifenden Kappe 33 aus einem weichelastischen Gummi- oder Kunststoffmaterial besteht. Die Kappe 33 ist im Umgreifungsbereich der Scheibe 3 faltenbalgartig ausgebildet und vermag daher auch der Bewegung des Knopfes 13 zu folgen, wenn dieser entgegen der Kraft der Feder 12 bewegt wird.Finally, FIG. 5 shows a sealing means for the upper part 1 of the fastening device, which consists of a cap 33 made of a soft elastic rubber or plastic material encompassing both the button 13 and the peripheral edge of the disk 3. The cap 33 has a bellows-like configuration in the area around the disk 3 and can therefore also follow the movement of the button 13 when it is moved against the force of the spring 12.
