Description

Die Erfindung betrifft einen Drehspannverschluss aufweisend ein in einer Tür oder Klappe ausgebildeten Öffnung festgelegtes Verschlussgehäuse, in welchem eine an ihrem freien Ende eine Schließzunge tragende Schließwelle mittels eines auf einem Betätigungsansatz aufzusetzenden Werkzeuges drehbar angeordnet ist und die Schließzunge zusätzlich zu ihrer Drehbewegung während eines Teils der Drehbewegung der Schließwelle um einen axialen Weg verschoben wird, wobei in dem Verschlussgehäuse eine darin drehbare Drehspannhülse mit einer Kulissenführung für einen die Schließwelle durchgreifenden Stift zur Bewirkung der axialen Verschiebung der Schließwelle bei Drehung der Drehspannhülse angeordnet ist.The invention relates to a rotary clamping device having a closure formed in a door or flap opening, in which a closing shaft at its free end carrying a locking shaft is rotatably mounted by means of aufzusetzenden a tool on a tool and the locking tongue in addition to its rotational movement during a portion of the rotational movement the closing shaft is displaced by an axial distance, wherein in the closure housing therein a rotatable rotary clamping sleeve is arranged with a slotted guide for a locking shaft by cross-pin for effecting the axial displacement of the closing shaft upon rotation of the rotary clamping sleeve.

Ein Drehspannverschluss mit den vorgenannten Merkmalen ist in der DE 298 05 849 U1 beschrieben. Bei einem derartigen Drehspannverschluss ist die Schließzunge gegenüber dem Betätigungsmechanismus derart angeordnet, dass nach Drehung der Schließzunge in deren Schließposition durch eine Weiterdrehung der die Schließzunge tragenden Schließwelle eine die Schließzunge unter Vorspannung in Anlage an einem die Tür oder Klappe haltenden Rahmenteil bringende axiale Bewegung der Schließzunge erreicht wird, so dass ein fester und sicherer Verschluss sichergestellt ist. Beim öffnen des Verschlusses wird zunächst die Schließzunge durch eine axiale Verschiebung von dem Rahmenteil abgehoben und erst anschließend in die Öffnungsposition gedreht, so dass eine Beaufschlagung des Rahmens bei den Drehbewegungen der Schließung jeweils vermieden ist. Bei dem in der DE 298 05 849 U1 beschriebenen Drehspannverschluss ist eine Steckschlüsselbetätigung einer in dem Verschlussgehäuse gelagerten und einen die Schließwelle durchsetzenden Stift tragenden Schließwelle vorgesehen, wobei die Enden des Stiftes in einer in das Verschlussgehäuse integrierten Kulissenführung geführt sind. Die Kulissenführung ist derart ausgebildet, dass in einem Teilbereich der Drehung der Schließwelle zusätzlich auch eine axiale Verschiebung der Schließwelle erfolgt. Mit dem bekannten Drehspannverschluss ist noch der Nachteil verbunden, dass von der Außenseite der Tür oder Klappe her nicht erkennbar ist, ob sich der Drehspannverschluss in der Öffnungsstellung für die Schließzunge oder in der Schließstellung dafür befindet.A rotary clamping closure with the aforementioned features is in the DE 298 05 849 U1 described. In such a rotary clamping closure, the locking tongue is arranged relative to the actuating mechanism such that after rotation of the locking tongue in its closed position by a further rotation of the closing shaft bearing the closing shaft a Locking tongue under bias in abutment on a door or flap holding frame member bringing axial movement of the locking tongue is achieved, so that a firm and secure closure is ensured. When the closure is opened, the closing tongue is first lifted off the frame part by an axial displacement and only subsequently turned into the opening position, so that loading of the frame during the rotational movements of the closure is avoided in each case. In the in the DE 298 05 849 U1 Rotary clamping closure described is provided a socket operation of a stored in the closure housing and the locking shaft passing through a pin supporting the locking shaft, wherein the ends of the pin are guided in an integrated into the closure housing slotted guide. The slotted guide is designed such that in a partial region of the rotation of the closing shaft in addition, an axial displacement of the closing shaft takes place. With the known rotary clamping closure is still connected the disadvantage that from the outside of the door or flap is not recognizable whether the rotary clamping device is in the open position for the locking tongue or in the closed position for it.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Drehspannverschluss mit den eingangs genannten Merkmalen zur Verfügung zu stellen, bei welchem der Funktionszustand des Verschlusses von außen erkennbar ist.The invention is therefore based on the object to provide a rotary clamping closure with the features mentioned in the available, in which the functional state of the closure can be seen from the outside.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgespaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Pantentansprüche, welche dieser Beschreibung nachgestellt sind.The solution to this problem arises, including advantageous splits and developments of the invention from the content of the claims, which are adjusted to this description.

Die Erfindung sieht in ihrem Grundgedanken vor, dass zusätzlich eine sowohl drehbare als auch in dem Verschlussgehäuse axial verschiebbare und den Betätigungsansatz aufweisende Betätigungswelle angeordnet ist, die in allen Stellungen drehfest mit der Drehspannhülse gekoppelt ist, wobei die Betätigungswelle eine Kulissenführung für einen das Verschlussgehäuse durchsetzenden Stift zur Bewirkung der axialen Verschiebung der Betätigungswelle bei Drehung der Betätigungswelle aufweist und Stift und Kulissenführung derart zueinander ausgerichtet sind, dass die Betätigungswelle bei geöffnetem Verschluss mit einem Abschnitt nach außen über das Verschlussgehäuse hervorsteht und bei vollständig geschlossenem Verschluss mit Drehung der Schließzunge in ihre Schließstellung und axialer Vorspannung der Schließwelle durch deren axiale Verschiebung bündig mit dem Verschlussgehäuse ist. Mit der Erfindung ist der Vorteil verbunden, dass unter Beibehaltung des mechanischen Aufbaus eines Drehspanuverschlusses es gleichwohl erkennbar ist, ob sich der Verschluss in seiner geschlossenen oder offenen Stellung befindet. Steht nämlich die Betätigungswelle nach außen über das Verschlussgehäuse vor, so ist die offene Stellung des Verschlusses gegeben. Schließt die Betätigungswelle mit dem Verschlussgehäuse bündig ab, so liegt die geschlossene Stellung vor.The invention provides in its basic idea that in addition a both rotatable and axially displaceable in the closure housing and the actuating lug having actuating shaft is arranged, which is rotatably coupled in all positions with the rotary clamping sleeve, wherein the actuating shaft has a slotted guide for a closure housing passing through pin for effecting the axial displacement of the actuating shaft upon rotation of the actuating shaft and pin and slide guide are aligned with each other in that, when the shutter is open, the actuating shaft protrudes with a portion outwardly beyond the shutter housing and is flush with the shutter housing when the shutter is fully closed, with the closing tongue rotating into its closed position and axially biasing the locking shaft by its axial displacement. The invention has the advantage that, while maintaining the mechanical construction of a Drehspanuverschlusses it is still recognizable whether the closure is in its closed or open position. In fact, if the actuating shaft projects outwardly beyond the closure housing, the open position of the closure is given. Closes the actuating shaft flush with the closure housing, so is the closed position.

Die Erkennbarkeit des Funktionszustandes des Drehspannverschlusses kann verbessert werden, soweit nach einem bevorzugten Ausführungsbeispiel der Erfindung vorgesehen ist, dass die Betätigungswelle auf ihrem bei geöffnetem Verschluss nach außen über das Verschlussgehäuse hervorstehenden Abschnitt mit einer Farbmarkierung versehen ist, die bei vollständig geschlossenem Verschluss mit bündiger Stellung der Betätigungswelle in dem Verschlussgehäuse nicht sichtbar ist.The recognizability of the functional state of the rotary clamping closure can be improved, as far as according to a preferred embodiment of the invention is provided that the actuating shaft is provided on its open with the shutter to the outside over the closure housing portion with a color marking, the fully closed closure with flush position of the Actuating shaft is not visible in the closure housing.

Hierzu kann in einer ersten Ausführungsform vorgesehen sein, dass die Farbmarkierung einfarbig ist, so dass die Farbmarkierung nur bei vollständig geschlossenem Verschluss und bündiger Stellung der Betätigungswelle in dem Verschlussgehäuse nicht mehr sichtbar ist. In dieser Ausführungsform ist an der Farbmarkierung nur erkennbar, ob der Drehspannverschluss offen ist oder ob er vollständig geschlossene, das heißt auch gespannt ist.For this purpose, it may be provided in a first embodiment that the color marking is monochrome, so that the color marking is no longer visible in the closure housing only when fully closed closure and flush position of the actuating shaft. In this embodiment is only recognizable on the color marking, whether the rotary clamping lock is open or whether it is completely closed, that is also stretched.

Gemäß einer alternativen Ausführungsform kann vorgesehen sein, dass die Farbmarkierung zweifarbig ist, von der die erste außenliegende Farbmarkierung in der Stellung des Verschlusses sichtbar bleibt, in der Schließzunge in ihre Schließstellung gedreht, jedoch noch nicht, axial verschoben und gespannt ist. Bei dieser Ausführungsform können beide möglichen Funktionszustände des Drehspannverschlusses sichtbar gemacht werden. Soweit beide Farben sichtbar sind, befindet sich der Verschluß in der vollständig offenen Stellung. Ist nur noch eine Farbe sichtbar und demnach die Betätigungswelle nur um einen Teilbetrag in das Verschlussgehäuse hineinverschobenn, so ist der Verschluss teilweise geschlossen insoweit, als die Schließzunge in ihre Schließstellung gedreht ist; allerdings ist der Drehspannverschluss noch nicht gespannt. Erst wenn aufgrund des bündigen Einschubs der Betätigungswelle in das Verschlussgehäuse die Farbmarkierung als solche nicht mehr erkennbar ist, befindet sich der Drehspannverschluss in seiner vollständig geschlossenen Stellung mit gespannter Schließzunge.According to an alternative embodiment it can be provided that the color marking is bicoloured, of which the first outer color marking remains visible in the position of the closure, in the closing tongue turned to its closed position, but not yet, axially displaced and stretched. In this embodiment, both possible functional states of the rotary clamping closure can be made visible. As far as both colors are visible, the shutter is in the fully open position. If only one more color is visible and therefore the actuating shaft is displaced into the closure housing only by a partial amount, the closure is partially closed insofar as the closing tongue is turned into its closed position; However, the rotary clamping lock is not yet excited. Only when the color marking is no longer recognizable as such due to the flush insertion of the actuating shaft in the closure housing, the rotary clamping device is in its fully closed position with cocked locking tongue.

Nach einem bevorzugten Ausführungsbeispiel der Erfindung ist vorgesehen, dass die Betätigungswelle gegenüber der Drehspannhülse in dem Verschlussgehäuse mittels einer Feder abgestützt ist, die die Betätigungswelle in deren nach außen über das Verschlussgehäuse hervorstehende Stellung vorspannt.According to a preferred embodiment of the invention it is provided that the actuating shaft relative to the rotary clamping sleeve is supported in the closure housing by means of a spring which biases the actuating shaft in its outwardly projecting beyond the closure housing position.

Zur Ausbildung der Führung der Betätigungswelle in dem Verschlussgehäuse kann vorgesehen sein, dass der das Verschlussgehäuse durchsetzende Stift mit seinen beiden Enden in der Gehäusewand des Verschlussgehäuses festgelegt ist und sich quer durch die Betätigungswelle erstreckt, wobei in der Wandung der Betätigungswelle zwei jeweils die Kulissenführung für den Stift ausbildende und sich über einen Teil des Umfangs der Betätigungswelle erstreckende Schlitze ausgebildet sind.To form the guide of the actuating shaft in the closure housing can be provided that the closure housing passing through pin is fixed with its two ends in the housing wall of the closure housing and extending transversely through the actuating shaft, wherein in the wall of the actuating shaft two each of the slotted guide for forming the pin and extending over a part of the circumference of the actuating shaft extending slots are formed.

Zur Abstützung der Betätigungswelle in der Schließstellung des Verschlusses kann vorgesehen sein, dass die Betätigungswelle mit einem außen umlaufenden Kragen bei vollständig geschlossenem Verschluss auf einem in dem Verschlussgehäuse innenseitig vorspringenden Absatz aufliegt, wenn die bündige Stellung der Betätigungswelle in dem Verschlussgehäuse erreicht ist.To support the actuating shaft in the closed position of the closure can be provided that the actuating shaft rests with an outer circumferential collar with fully closed closure on a inside projecting in the closure housing paragraph when the flush position of the actuating shaft is reached in the closure housing.

Soweit durch die Anbringung eines die Seitenwände des Verschlussgehäuses und die Betätigungswelle durchgreifenden Stiftes sich ein Dichtungsproblem für den Drehspannverschluss ergibt, ist nach einem bevorzugten Ausführungsbeispiel der Erfindung vorgesehen, dass die Betätigungswelle mittels einer auf ihrem äußeren Umfang angeordneten Dichtung bei geschlossenem Verschluss gegen das Verschlussgehäuse abgedichtet ist. In diesem Fall kann vorgesehen sein, dass die Farbmarkierung auf der Außenseite der Dichtung angebracht ist.Insofar as the attachment of a side wall of the closure housing and the actuating shaft cross pin results in a sealing problem for the rotary clamping closure is provided according to a preferred embodiment of the invention that the actuating shaft is sealed by a arranged on its outer circumference seal with closed closure against the closure housing , In this case it can be provided that the color marking is mounted on the outside of the seal.

Die Kulissenführung 22 besteht aus einem sich schraubenartig über die Längserstreckung der Drehspannhülse 16 verlaufenden Schlitz 23, an dessen (vorderen) Ende ein in Umfangsrichtung ausgebildeter Halteabschnitt 24 anschließt. Weiterhin ist ein die Drehspannhülse 16 außen umgreifender und die Kulissenführung 22 mit darin laufenden Enden des Stiftes 21 übergreifende Schaltring 25 angeordnet, der seinerseits in einer im Einzelnen nicht dargestellten Weise drehfest im In-neren des Verschlussgehäuses 11 festgelegt ist. Der Schaltring 25 weist im Bereich der Kulissenführung 22 jeweils eine fensterartige Ausnehmung 26 auf, mittels deren Steuerkanten 27 zur Steuerung der in der Kulissenführung 22 laufenden Enden des Stiftes 21 gebildet ist. Es ist eine sich zwischen der Drehspannhülse 16 und dem Sicherungsring 19 für die Schließzunge 18 abstützende Feder 29 vorgesehen, die die Schließzunge 18 um ihre äußere, von einem Rahmen abgehobene Stellung vorspannt.For rotational movement and axial displacement of the closing shaft 17 in the rotary clamping sleeve 16, the closing shaft 17 is provided with a transversely passing through pin 21 which is guided in a slotted guide 22 of the rotary clamping sleeve 16. The link guide 22 consists of a helically extending over the longitudinal extent of the rotary clamping sleeve 16 slot 23, at the (front) end of a trained in the circumferential direction holding portion 24 connects. Furthermore, the rotary clamping sleeve 16 outside encompassing and the slotted guide 22 with therein ends of the pin 21 cross-switching ring 25 is arranged, which in turn is rotatably fixed in a manner not shown in detail in the interior of the closure housing 11. The switching ring 25 has in the region of the guide slot 22 each have a window-like recess 26, by means of the control edges 27 is formed to control the running in the slotted guide 22 ends of the pin 21. There is provided a spring 29 supported between the rotary clamping sleeve 16 and the retaining ring 19 for the locking tongue 18, which biases the locking tongue 18 about its outer position raised from a frame.

Zusätzlich ist in dem Verschlussgehäuse 11 eine Betätugungswelle 30 sowohl drehbar als auch axial verschiebbar angeordnet, die an ihrem vorderen (linken) Ende einen Betätigungsansatz 41 zum Ansetzen eines Werkzeuges für die Drehung der Betätigungswelle 30 aufweist. Auf ihrer gegenüberliegenden (inneren) Seite greift die Betätigungswelle 30 mit einer nicht weiter dargestellten Ausnehmung auf einen Vierkant 28 der Drehspannhülse 16, so dass sich in allen Funktionsstellungen des Verschlusses eine drehfeste Verbindung zwischen der Betätigungswelle 30 und der Drehspannhülse 16 ergibt. Zur Herbeiführung einer axialen Verschiebung der Betätigungswelle 30 bei deren Drehbewegung ist ein das Verschlussgehäuse 11 in zugeordneten Bohrungen 32 durchsetzender Stift 31 vorgesehen, der die Betätigungswelle 30 in zwei in deren Wandung ausgebildeten und somit als Kulissenführung wirkenden Schlitzen 33 durchgreift. Die beiden symmetrisch angeordneten, jeweils um 180° versetzt angeordneten Schlitze weisen einen sich schraubenartig über die Längserstreckung der Betätigungswelle 30 erstreckenden Verlauf auf, so dass mit der Drehung der Betätigungswelle 30 eine zwangsgesteuerte Axialverschiebung der Betätigungswelle 30 in dem Verschlussgehäuse 11 verbunden ist. Aufgrund des Eingriffes der Betätigungswelle 30 mit dem Vierkant 28 der Drehspannhülse 16 wird in allen Drehstellungen und axial verschobenen Stellungen der Betätigungswelle 30 die Drehbewegung der Betätigungswelle 30 in eine Drehbewegung der Drehspannhülse 16 umgesetzt.In addition, in the closure housing 11 a Betätigungsugungswelle 30 is both rotatable and axially displaceable, which has at its front (left) end an actuating lug 41 for applying a tool for the rotation of the actuating shaft 30. On its opposite (inner) side, the actuating shaft 30 engages with a not further shown recess on a square 28 of the rotary clamping sleeve 16, so that in all functional positions of the closure a rotationally fixed connection between the actuating shaft 30 and the rotary clamping sleeve 16 results. To bring about an axial displacement of the actuating shaft 30 during the rotational movement of the closure housing 11 is provided in associated holes 32 passing through pin 31, which passes through the actuating shaft 30 in two formed in the wall and thus acting as a slotted guide slots 33. The two symmetrically arranged, each offset by 180 ° slots arranged have a helically extending over the longitudinal extension of the actuating shaft 30 course, so that with the rotation of the actuating shaft 30 a positively controlled axial displacement of the actuating shaft 30 is connected in the closure housing 11. Due to the engagement of the actuating shaft 30 with the square 28 of the rotary clamping sleeve 16, the rotational movement of the actuating shaft 30 is converted into a rotational movement of the rotary clamping sleeve 16 in all rotational positions and axially displaced positions of the actuating shaft 30.

Der in dem Verschlussgehäuse 11 festgelegte Stift 31 und die an der Betätigungswelle 30 ausgebildete Kulissenführung in Form der Schlitze 33 sind derart zueinander ausgerichtet, dass die Betätigungswelle 30 bei geöffnetem Verschluss mit einem Abschnitt 34 nach außen über das Verschlussgehäuse 11 hervorsteht. Auf diesem Abschnitt 34 ist eine Nut 35 mit einer darin eingelegten Dichtung 36 angeordnet. Ferner ist eine sich zwischen der Betätigungswelle 30 und der Drehspannhülse 16 abstützende Feder 37 vorgesehen, die die Betätigungswelle 30 in deren nach außen über das Verschlussgehäuse 11 hervorstehende Stellung vorspannt. Zur Begrenzung der axialen Verschiebung der Betätigungswelle 30 in dem Verschlussgehäuse 11 ist der Abschnitt 34 in Form eines nach außen vorstehenden Kragens 42 ausgebildet, der bei in das Verschlussgehäuse 11 vollständig hineinverschobener Stellung in Anlage an einem in dem Verschlussgehäuse innenseitig vorspringenden Absatz 43 gelangt. In dieser Stellung ist eine bündige Stellung der Betätigungswelle 30 in dem Verschlussgehäuse 11 gegeben.The fixed in the closure housing 11 pin 31 and formed on the actuating shaft 30 slotted guide in the form of slots 33 are aligned with each other so that the actuating shaft 30 protrudes with the shutter open with a portion 34 to the outside over the closure housing 11. On this section 34, a groove 35 is arranged with a seal 36 inserted therein. Further, a spring 37 supported between the operating shaft 30 and the rotary clamping sleeve 16 is provided, which biases the actuating shaft 30 in its outwardly projecting position over the shutter housing 11. In order to limit the axial displacement of the actuating shaft 30 in the closure housing 11, the portion 34 is formed in the form of an outwardly projecting collar 42 which comes into abutment with a projecting into the closure housing 11 inside paragraph 43 in fully displaced into the closure housing position. In this position, a flush position of the actuating shaft 30 is given in the closure housing 11.

Wie sich aus Figur 2 entnehmen lässt, steht bei zusammengebautem Drehspannverschluss die Betätigungswelle 30 mit dem Abschnitt 34 bei geöffnetem Verschluss mit dem Abschnitt 34 über das Verschlussgehäuse 11 hervor, wobei auf dem Abschnitt 34 eine wenigstens aus einer Farbe bestehende Farbmarkierung aufgebracht ist. In der in Figur 2 dargestellten Offenstellung des Verschlusses ist daher aufgrund der nach außen vorstehenden Betätigungswelle 30 die auf dem zugeordneten Abschnitt 34 befindliche Farbmarkierung sichtbar.As it turned out FIG. 2 can be seen stands in assembled rotary clamping the actuating shaft 30 with the section 34 with the shutter open with the section 34 on the closure housing 11, wherein on the portion 34 is a color mark consisting of at least one color is applied. In the in FIG. 2 illustrated open position of the closure is therefore visible due to the outwardly projecting actuating shaft 30 located on the associated portion 34 color marking.

Wird nun der Drehspannverschluss gemäß Figur 2 in Funktion gesetzt, wird ein nicht dargestelltes Werkzeug, beispielsweise ein Schlüssel, auf den Betätigungsansatz 41 der Betätigungswelle 30 aufgesetzt, und es wird die Betätigungswelle 30 im Uhrzeigersinn gedreht. Bei dieser Drehung wird gleichzeitig aufgrund der Zwangsführung der Betätigungswelle durch den Stift 31 und die Schlitze 33 die Betätigungswelle 30 axial in das Verschlussgehäuse 11 hineinverschoben. Diese Axialverschiebung relativ zu der in dem Verschlussgehäuse 11 ortsfest, aber drehbar angeordneten Drehspannhülse 16 wird dadurch ausgeglichen, dass der an der Drehspannhtilse 16 befindliche Vierkant 28 unterschiedlich tief in die Betätigungswelle 30 eingreift. Soweit sich die Betätigungswelle 30 in der Offenstellung des Verschlusses mittels einer Feder 37 gegen die Drehspannhülse 16 abstützt, wird bei der durch die Drehung der Betätigungswelle 30 bewirkten Axialverschiebung der Betätigungswelle 30 gegenüber der Drehspannhülse 16 die Feder 37 gespannt.Now, the rotary clamping lock according to FIG. 2 put into operation, an unillustrated tool, such as a key, placed on the operating lug 41 of the actuating shaft 30, and it is the actuating shaft 30 is rotated clockwise. During this rotation, the actuating shaft 30 is simultaneously displaced axially into the closure housing 11 due to the positive guidance of the actuating shaft by the pin 31 and the slots 33. This axial displacement relative to the stationary in the closure housing 11, but rotatably mounted rotary clamping sleeve 16 is compensated for by the fact that located on the Drehspannhtilse 16 square 28 engages different depths in the actuating shaft 30. As far as the actuating shaft 30 is supported in the open position of the closure by means of a spring 37 against the rotary clamping sleeve 16, the spring 37 is tensioned in the caused by the rotation of the actuating shaft 30 axial displacement of the actuating shaft 30 relative to the rotary clamping sleeve 16.

Gleichzeitig mit der Drehung der Betätigungswelle 30 wird auch die in dem Verschlussgehäuse 11 gelagerte Drehspannhülse 16 mitgenommen und in Drehung versetzt. Wie im Stand der Technik hinsichtlich der Funktion eines Drehspannverschlusses an sich bekannt, erfolgt bei Drehung der Drehspannhülse 16 aufgrund der von ihr mitgenommenen Schließwelle 17 eine Drehung der Schließzunge 18 in deren Schließstellung, in welcher die Schließzunge 18 ein zugeordnetes Rahmenteil hintergreift. Dabei liegt die Schließzunge 18 noch nicht gegen den Rahmen an, sondern wird erst durch eine Weiterdrehung der Drehspannhülse 16 aufgrund einer durch die Kulissenführung 22 vorgenommenen Führung des Stiftes 21 bewirkten Axialverschiebung in gespannte Anlage an dem Rahmenteil gebracht. Bei der diesbezüglichen Weiterdrehung der Drehspannhülse 16 nämlich wird der Stift 21 der Schließwelle 17 an den Steuerkanten 27 des Schaltringes 25 festgelegt, so dass sich bei einer weiteren Relativdrehung der Drehspannhülse 16 gegenüber der nunmehr festgelegten Schließwelle 17 die Schließwelle 17 aufgrund von deren Führung über die Enden des Stiftes 21 in dem Gewindeschlitz 23 der Kulissenführung 22 axial verschoben, bis die Enden des Stiftes 21 in dem jeweiligen Halteabschnitt 24 der Kulissenführung 22 zu liegen kommen, so dass damit die Schließstellung der Schließzunge 18 erreicht ist, in welcher die Schließzunge 18 gegen das betreffende Rahmenteil vorgespannt ist. Bei der axialen Verschiebung der Schließwelle 17 wird die Feder 29 gespannt, die somit die Schließwelle 17 in deren Stellung mit von dem Rahmenteil abgehobener Schließzunge 18 vorspannt.Simultaneously with the rotation of the actuating shaft 30 and the mounted in the closure housing 11 rotary clamping sleeve 16 is taken and rotated. As known in the art with respect to the function of a rotary clamping closure per se, upon rotation of the rotary clamping sleeve 16 due to the entrained by her closing shaft 17, a rotation of the locking tongue 18 in its closed position, in which the locking tongue 18 engages behind an associated frame part. In this case, the locking tab 18 is not yet against the frame, but is brought only by a further rotation of the rotary clamping sleeve 16 caused due to a made by the slide guide 22 guiding the pin 21 axial displacement in tensioned contact with the frame part. In the relevant further rotation of the rotary clamping sleeve 16 namely the pin 21 of the closing shaft 17 is fixed to the control edges 27 of the switching ring 25, so that in a further relative rotation of the rotary clamping sleeve 16th relative to the now defined closing shaft 17, the closing shaft 17 due to their leadership over the ends of the pin 21 in the threaded slot 23 of the slide guide 22 axially displaced until the ends of the pin 21 in the respective holding portion 24 of the slide guide 22 come to rest, so that so the closed position of the locking tongue 18 is reached, in which the locking tongue 18 is biased against the relevant frame part. During the axial displacement of the closing shaft 17, the spring 29 is tensioned, thus biasing the closing shaft 17 in its position with the locking member 18 lifted from the frame part.

Soll nun der Drehspannverschluss wieder geöffnet werden, so führt eine Drehung der Betätigungswelle 30 mit Drehspannhülse 16 in die Öffnungsrichtung aufgrund des Anschlages der Enden des Stiftes 21 gegen die zugeordneten Steuerkanten 27 des drehfest mit dem Verschlussgehäuse 11 verbundenen Schaltringes 25 dazu, dass die Stiftenden aus dem Halteabschnitt 24 der Kulissenführung 22 heraustreten, so dass die gespannte Feder 29 die Schließwelle 17 nun bei gleichzeitiger Rückdrehung axial verschiebt und somit in eine Stellung verbringt, in welcher die von der Schließwelle 17 getragene Schließzunge 18 von dem zugeordneten Rahmenteil abgehoben ist. Durch eine weitere Drehung der Betätigungswelle 30 mit Drehspannhülse 16 wird die Schließzunge 18 in deren Öffnungsstellung verbracht.If now the rotary clamping closure are opened again, then a rotation of the actuating shaft 30 with rotary clamping sleeve 16 in the opening direction due to the abutment of the ends of the pin 21 against the associated control edges 27 of the rotatably connected to the closure housing 11 switching ring 25 causes the pin ends of the Retaining portion 24 of the slotted guide 22 come out, so that the tensioned spring 29, the locking shaft 17 now axially displaced during simultaneous reverse rotation and thus spends into a position in which the carried by the closing shaft 17 locking tab 18 is lifted from the associated frame part. By a further rotation of the actuating shaft 30 with rotary clamping sleeve 16, the locking tongue 18 is spent in its open position.

Soweit in der in Figur 2 dargestellten Offenstellung des Verschlusses der Abschnitt 34 der Betätigungswelle 30 nach außen über das Verschlussgehäuse 11 hervorsteht und bevorzugt vorgesehen ist, dass dieser Abschnitt 34 mit einer Farbmarkierung versehen ist, ist die Offenstellung des Drehspannverschlusses 10 leicht erkennbar, solange die Farbmarkierung sichtbar ist. Wird der Drehspannverschluss 10 durch Drehung der Betätigungswelle 30 in seine Schließstellung überführt, so führt die damit zwangsgeführt erfolgende Axialverschiebung der Betätigungswelle 30 in das Verschlussgehäuse 11 hinein zu einem Verschwinden des Abschnitts 34 in dem Verschlussgehäuse 11, so dass in der vollständig geschlossenen Stellung des Verschlusses gemäß Figur 3 die auf dem Abschnitt 34 befindliche Farbmarkierung nicht mehr erkennbar ist.As far as in FIG. 2 illustrated open position of the closure of the portion 34 of the actuating shaft 30 protrudes outwardly beyond the closure housing 11 and is preferably provided that this section 34 is provided with a color marking, the open position of the rotary clamping closure 10 is easily recognizable, as long as the color mark is visible. If the rotary clamping closure 10 is transferred into its closed position by rotation of the actuating shaft 30, the axial displacement of the actuating shaft 30, which is thus forcedly performed, results in the closure housing 11 into a disappearance of the portion 34 in the closure housing 11, so that in the fully closed position of the closure according to FIG. 3 the color mark located on the section 34 is no longer recognizable.

Wie nicht weiter dargestellt ist, kann der axiale Verschiebeweg der Betätigungswelle 30 in dem Verschlussgehäuse 11 so breit ausgelegt sein, dass auf dem Abschnitt 34 eine doppelte Farbmarkierung mit zwei unterschiedlichen Farben angebracht sein kann. Hierbei sind zunächst bei geöffnetem Verschluss gemäß Figur 2 beide Farbmarkierungen sichtbar. Wird dann durch Drehung der Betätigungswelle 30 zunächst lediglich die Schließzunge 18 in ihre gedrehte Schließstellung verbracht, so reicht der damit verbundene Einschubweg der Betätigungswelle 30 in das Verschlussgehäuse 11 nur aus, um die innenliegende zweite Farbmarkierung in das Verschlussgehäuse 11 eintreten zu lassen; die erste außenliegende Farbmarkierung bleibt in dieser Stellung des Verschlusses noch sichtbar. Erst wenn die Betätigungswelle 30 so weit weitergedreht ist, dass die Schließzunge 18 durch axiale Verschiebung der Schließwelle 17 gespannt und demzufolge eine bündige Lage der Betätigungswelle 30 in dem Verschlussgehäuse 11 erreicht ist, ist die Farbmarkierung nicht mehr sichtbar, so dass die vollständig geschlossene Stellung des Verschlusses von außen detektierbar ist.As not further shown, the axial displacement of the actuating shaft 30 may be designed in the closure housing 11 so wide that on the portion 34, a double color mark with two different colors may be appropriate. These are initially with open closure according to FIG. 2 both color markings visible. If, by rotation of the actuating shaft 30, initially only the closing tongue 18 is brought into its turned closed position, then the associated insertion path of the actuating shaft 30 into the closure housing 11 is sufficient only to allow the inner second color marking to enter the closure housing 11; the first outer color marking remains visible in this position of the closure. Only when the actuating shaft 30 is further rotated so far that the closing tongue 18 is tensioned by axial displacement of the closing shaft 17 and consequently a flush position of the actuating shaft 30 in the closure housing 11 is reached, the color marking is no longer visible, so that the fully closed position of Closure is detectable from the outside.
