Um vorteilhafte, schlanke Konstruktionsverhältnisse zu schaffen, wird vorgeschlagen dass der Bajonettverschluss an einem Kupplungsteil ein in Kupplungsrichtung um die Drehachse (4) verlaufendes Steilgewinde (6) umfasst, an das ein entgegengesetzt der Eindrehrichtung (E) beim Kuppeln verlaufender Querschlitz (7) angesetzt ist und dass im Kupplungsbereich zwischen beiden Kupplungsteilen eine Feder (8) vorgesehen ist, die beim Kuppeln derart an beiden Kupplungsteilen (2, 3) drehfest abgestützt ist, dass sich die Feder (8) beim Kupplungsvorgang in und um die Drehachse (4) spannt und einen am anderen Kupplungsteil vorgesehenen Kupplungsansatz (9), der in das Steilgewinde (6) eingreift, in Kupplungsstellung im Querschlitz (7) sichert.A quick coupling (1) is described for releasably connecting two cylindrical coupling parts (2, 3) in the direction of their axis of rotation (4) with a bayonet lock (5). In order to create advantageous, slim construction conditions, it is proposed that the bayonet lock on a coupling part comprises a steep thread (6) which runs in the coupling direction around the axis of rotation (4), to which a transverse slot (7) which runs in the opposite direction to the screw-in direction (E) during coupling is attached and that a spring (8) is provided in the coupling area between the two coupling parts, which is supported in a rotationally fixed manner on both coupling parts (2, 3) during coupling in such a way that the spring (8) is tensioned in and around the axis of rotation (4) during the coupling process and secures a coupling extension (9) provided on the other coupling part, which engages in the steep thread (6), in the coupling position in the transverse slot (7).
Description
Die Erfindung bezieht sich auf Schnellkupplung zum lösbaren Verbinden zweier zylinderförmiger Kupplungsteile in Richtung Ihrer Drehachse mit einem Bajonettverschluss. The invention relates to quick coupling for releasably connecting two cylindrical coupling parts in the direction of their axis of rotation with a bayonet lock.
Bekannte derartige Schnellkupplungen sind beispielsweise Feuerwehrkupplungen, also insbesondere Schlauchkupplungen zum Verbinden von Feuerwehrschläuchen und Armaturen. Der bekannteste Vertreter dieser Kupplungen ist wohl die StorzKupplung, eine symmetrische hermaphrodite Kupplung, d. h. die zu kuppelnden Anschlussarmaturen sind auf der Kupplungsseite identisch und können beliebig verbunden werden. Darüber hinaus gibt es auch Schnellkupplungen, bei denen die beiden Enden eines Schlauches oder einer Armatur zwar gegengleiche aber konstruktiv unterschiedliche Kupplungsteile aufweisen. Die bekannten Schnellkupplungen dienen nicht nur einem Verbinden zweier Leitungen, sondern können auch zum lösbaren Verbinden nahezu beliebiger Konstruktionselemente Known quick couplings of this type are, for example, fire brigade couplings, in particular hose couplings for connecting fire hoses and fittings. The best-known representative of these couplings is probably the Storz coupling, a symmetrical hermaphrodite coupling, i.e. H. The connection fittings to be coupled are identical on the coupling side and can be connected in any way. There are also quick couplings in which the two ends of a hose or fitting have identical but structurally different coupling parts. The well-known quick couplings are not only used to connect two lines, but can also be used to releasably connect almost any construction elements
verwendet werden. be used.
Schnellkupplungen der eingangs geschilderten Art eignen sich auch zum Verschließen von Behältern oder Leitungen. Einen Verschluss für Behälter offenbart beispielsweise die CH528416A, insbesondere für Krüge, Flaschen und Kannen. Der Verschluss umfasst eine gegen die Behälterinnenwand drückende Dichtung, wobei der Verschluss ein elastisches Verschlussorgan aufweist, das mit einem Bedienungsorgan derart in Arbeitsverbindung steht, dass der Dichtungsdruck durch elastische Wirkung selbsttätig erzeugt wird. Zum Vorspannen des elastischen Verschlussorgans in Richtung der Drehachse zum Anpressen des Verschlussorgans gegen die Behälterinnenwand ist ein Spannmechanismus Quick couplings of the type described above are also suitable for closing containers or lines. CH528416A, for example, discloses a closure for containers, especially for jugs, bottles and jugs. The closure comprises a seal that presses against the inner wall of the container, the closure having an elastic closure member which is in working connection with an operating member in such a way that the sealing pressure is automatically generated by an elastic effect. A tensioning mechanism is used to pretension the elastic closure element in the direction of the axis of rotation in order to press the closure element against the inner wall of the container

Die FR2662427 zeigt eine Schnellkupplung für eine Flasche, wobei durch ein hinunterdrücken der Kappe eine Feder zusammengedrückt wird und elastische Metallplättchen den Flaschenkopf hintergreifend einrasten. Durch ein Drehen der Kappe kann die Schnellkupplung wieder gelöst werden. Eine ähnliche Schnellkupplung ist aus der DE 360756 C bekannt, die eine Metallhaube mit einem daran federnd gehaltenen Flaschenstoppel trägt. Sobald der Flaschenstoppel auf einen oberen Mündungsrand der Flasche aufgesetzt ist, wird die Feder wiederum durch hinunterdrücken der Metallhaube zusammengedrückt. Vollständig aufgesetzt hintergreifen wiederum Metallhaubenansätze den Flaschenkopf. Ein auf die konische Metallhaube aufgesetzter Spannring verrastet in der Verschlussstellung FR2662427 shows a quick coupling for a bottle, in which a spring is compressed by pressing down the cap and elastic metal plates engage behind the bottle head. The quick coupling can be released again by turning the cap. A similar quick coupling is known from DE 360756 C, which carries a metal hood with a bottle stopper held resiliently on it. As soon as the bottle stopper is placed on the upper edge of the mouth of the bottle, the spring is again compressed by pressing down the metal hood. When fully attached, metal hood attachments reach behind the bottle head. A clamping ring placed on the conical metal hood locks into the closed position
mit der Metallhaube und kann durch Drehen wieder gelöst werden. with the metal hood and can be released again by turning.
Nachteilig am Stand der Technik ist insbesondere die nicht unerhebliche Baugröße einer Storz-Kupplung bzw. die mangelnde mechanische Belastbarkeit der bekannten Flaschenkupplungen für rauere Einsatzzwecke. A particular disadvantage of the prior art is the not insignificant size of a Storz coupling and the lack of mechanical strength of the known bottle couplings for rougher applications.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Schnellkupplung der eingangs geschilderten Art anzugeben, die eine gegenseitige, sichere und robuste Verriegelung zweier Kupplungsteile gestattet und leicht lösbar ist. The invention is therefore based on the object of specifying a quick coupling of the type described at the beginning, which allows a mutual, secure and robust locking of two coupling parts and is easily detachable.
Die Erfindung löst die gestellte Aufgabe dadurch, dass der Bajonettverschluss an einem Kupplungsteil ein in Kupplungsrichtung um die Längsachse verlaufendes Steilgewinde umfasst, an das ein entgegengesetzt der Eindrehrichtung beim Kuppeln verlaufender Querschlitz angesetzt ist und dass im Kupplungsbereich zwischen beiden Kupplungsteilen eine Feder vorgesehen ist, die beim Kuppeln derart an beiden Kupplungsteilen drehfest abgestützt ist, dass sich die Feder beim Kupplungsvorgang in und um die Drehachse spannt und einen am anderen Kupplungsteil vorgesehenen Kupplungsansatz, der in das Steilgewinde eingreift, in Kupplungsstellung im Querschlitz sichert. The invention solves the problem in that the bayonet lock on a coupling part comprises a steep thread running in the coupling direction around the longitudinal axis, to which a transverse slot is attached which runs in the opposite direction to the direction of screwing in during coupling and that a spring is provided in the coupling area between the two coupling parts Couplings are supported in a rotationally fixed manner on both coupling parts in such a way that the spring is tensioned in and around the axis of rotation during the coupling process and secures a coupling extension provided on the other coupling part, which engages in the high-helix thread, in the coupling position in the transverse slot.
Zur Verbesserung der mechanischen Festigkeit und Haltbarkeit der Schnellkupplung kann das Steilgewinde mehrgängig ausgebildet sein. Dies erlaubt To improve the mechanical strength and durability of the quick coupling, the high-helix thread can be designed to have multiple threads. This allows
es auch Bauteile mit unterschiedlichem Winkelversatz zueinander zu montieren. It is also possible to assemble components with different angular offsets to one another.
Um einen besonders sicheren Halt des Kupplungsansatzes im Querschlitz in der Kupplungsstellung sicherzustellen, ist es von Vorteil, wenn der Querschlitz quer zur Drehachse, insbesondere gegen die Kupplungsrichtung zurücklaufend, ausgerichtet ist. Ist der Querschlitz gegen die Kupplungsrichtung zurücklaufend bewirkt dies, dass der Kupplungsansatz von der Feder nicht nur um die Drehachse, sondern auch in Richtung der Drehachse gegen das Querschlitzende angestellt wird. In order to ensure a particularly secure hold of the coupling extension in the transverse slot in the coupling position, it is advantageous if the transverse slot is aligned transversely to the axis of rotation, in particular running back against the coupling direction. If the transverse slot runs back against the coupling direction, this causes the coupling extension to be adjusted by the spring not only around the axis of rotation, but also in the direction of the axis of rotation against the end of the transverse slot.
Die Verdrehsicherung kann nach Art einer Klauenkupplung ausgebildet sein, bei der an der Feder vorgesehene Klauenansätze in entsprechende Nuten des anderen Kupplungsteils eingreift. Eine etwas elegantere Form der Verdrehsicherung ist eine Klauenkupplung, bei der an der Feder ein Spannteller befestigt ist, der eine um die Drehachse umlaufende wellenförmige Oberfläche ausbildet, die in entsprechende, gegengleiche dem anderen Kupplungsteil zugeordnete Wellenberge und -täler eingreift. Die Verdrehsicherung kann in einem besonders einfachen Fall auch eine Art Reibkupplung, beispielsweise ein auf eine Flaschen- oder Rohrstirnseite The anti-rotation device can be designed in the manner of a claw coupling, in which claw lugs provided on the spring engage in corresponding grooves in the other coupling part. A somewhat more elegant form of anti-twist protection is a claw coupling, in which a clamping plate is attached to the spring, which forms a wave-shaped surface that runs around the axis of rotation and which engages in corresponding wave crests and troughs assigned to the other coupling part. In a particularly simple case, the anti-twist device can also be a type of friction clutch, for example one on the end face of a bottle or pipe
aufgesetzter Gummistopfen sein. attached rubber stopper.
Ebenso kann die Verdrehsicherung nach Art einer formschlüssigen Verbindung ausgebildet sein, bei der die Feder über ein von der Kreisform abweichendes Profil an das andere Kupplungsteil angesetzt ist. Das Profil kann beispielsweise einen Likewise, the anti-rotation device can be designed in the manner of a positive connection, in which the spring is attached to the other coupling part via a profile that deviates from the circular shape. The profile can, for example, have one
elliptischen bzw. einen Polygonquerschitt aufweisen. have an elliptical or polygonal cross-section.
Für eine Fluiddichte Verbindung können die beiden Kupplungsteile in der Kupplungsstellung stirnseitig unter Zwischenlage einer Dichtung, insbesondere eines Dichtungsringes, aneinander anliegen. Damit ergibt sich eine zusätzliche Verspannung der Kupplung, wobei durch das Vorsehen eines elastischen Dichtungsringes eine Doppelpassung vermieden werden kann, da die Dichtung den erforderlichen Toleranzausgleich sicherstellt. For a fluid-tight connection, the two coupling parts can rest against each other on the front side in the coupling position with the interposition of a seal, in particular a sealing ring. This results in additional tensioning of the coupling, whereby a double fit can be avoided by providing an elastic sealing ring, since the seal ensures the necessary tolerance compensation.
Die erfindungsgemäße Schnellkupplung eignet sich zum Verbinden verschiedenster The quick coupling according to the invention is suitable for connecting a wide variety of things

Alternativ können auch beide Kupplungsteile als Schlauch- oder Rohranschlusskupplung ausgebildet sein, was insbesondere dann von Vorteil ist, wenn besonders schlanke Kupplungen erforderlich sind. Alternatively, both coupling parts can be designed as a hose or pipe connection coupling, which is particularly advantageous when particularly slim couplings are required.

The anti-rotation device can be designed in the manner of a claw coupling, in which claw lugs 11 provided on the spring engage in corresponding grooves 12 of the other coupling part. The anti-rotation device can also be designed in the manner of a claw coupling, in which a clamping plate 13 is attached to the spring, which forms a wave-shaped surface that runs around the axis of rotation 4 and which engages in corresponding, opposite wave crests and troughs assigned to the other coupling part, i.e practically corresponds to a face claw coupling.
Darüber hinaus kann die Verdrehsicherung nach Art einer formschlüssigen Verbindung ausgebildet sein, bei der die Feder über ein von der Kreisform abweichendes Profil an das andere Kupplungsteil angesetzt ist, beispielsweise elliptisch oder nach Art eines Polygons. In addition, the anti-rotation device can be designed in the manner of a positive connection, in which the spring is attached to the other coupling part via a profile that deviates from the circular shape, for example elliptically or in the manner of a polygon.
