Der Innendeckel 123, die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4, der Drehverschluss 107 und die Abdeckkappe sind beispielsweise aus Spritzgussteilen gebildet. Fig. 3 shows an exploded view of the closure element 101. The closure element 101 comprises an inner lid 123, the locking slide 105-1, 105-2, 105-3 and 105-4 and the rotary closure 107 and a cap, not shown. The inner lid 123, the lock slides 105-1, 105-2, 105-3 and 105-4, the screw cap 107 and the cap are formed of, for example, injection-molded parts.

Der Innendeckel 123 ist durch konzentrisch um den Drehverschluss 107 umlaufende Verstärkungsrippen 117 verstärkt. Die Verstärkungsrippen 117 bilden gleichzeitig eine Führung für die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4. Zu diesem Zweck umfassen die Verstärkungsrippen 117 Ausnehmungen, in denen die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 eingelegt werden.The inner lid 123 is reinforced by concentrically around the rotary closure 107 circumferential reinforcing ribs 117. The reinforcing ribs 117 at the same time form a guide for the locking slides 105-1, 105-2, 105-3 and 105-4. For this purpose, the reinforcing ribs 117 comprise recesses in which the locking slides 105-1, 105-2, 105-3 and 105-4 are inserted.

Die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 sind durch einen elastischen Federring 115 miteinander verbunden, so dass dem System eine Vorspannung verliehen wird und beim Einsetzen des Verschlusselementes 101 eine zuverlässige Verrastung und eine Verriegelung gewährleistet wird.The locking slides 105-1, 105-2, 105-3 and 105-4 are connected by an elastic spring ring 115 with each other, so that the system is given a bias and when inserting the closure member 101, a reliable locking and locking is ensured.

Der Drehverschluss 107 ist mit einer Schraube 125 an einer Drehachse 127 des Innendeckels 123 befestigt. Der Drehverschluss 107 ist kreisförmig ausgebildet und weist in der Mitte eine schüsselartige Vertiefung 121 auf. Quer durch die Vertiefung 121 erstreckt sich das Griffelement 119, so dass der Drehverschluss 107 keine hervorstehenden Teile aufweist.The rotary closure 107 is fastened with a screw 125 to a rotation axis 127 of the inner cover 123. The rotary closure 107 is circular and has in the center of a bowl-like depression 121. Transversely through the depression 121, the grip element 119 extends, so that the rotary closure 107 has no protruding parts.

Fig. 4A zeigt eine Rückansicht des Verschlusselementes 101 mit den Verriegelungsschiebern 105-1, 105-2, 105-3 und 105-4 in der geschlossenen Position. An der Rückseite des Drehverschlusses 107 befindet sich eine spiralförmige Nut 109 zum Einsetzen eines Betätigungsabschnittes 111 des Verriegelungsschiebers 105. Durch den Betätigungsabschnitt 111 in der spiralförmigen Nut 109 des Drehverschlusses 107 werden die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 beim Drehen des Drehverschlusses 107 translatorisch bewegt. Fig. 4A shows a rear view of the closure element 101 with the locking slides 105-1, 105-2, 105-3 and 105-4 in the closed position. At the rear of the rotary shutter 107 is a spiral groove 109 for inserting an operation portion 111 of the lock slider 105. By the operation portion 111 in the spiral groove 109 of the rotary shutter 107, the lock slides 105-1, 105-2, 105-3 and 105- 4 translationally moved during rotation of the rotary closure 107.

Durch eine Schwenkbewegung des Drehverschlusses 107 um 90° Grad erfolgt eine lineare Verriegelung des Verschlusselementes 101 gleichzeitig an vier Punkten. Dabei werden die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 über die durch die Nut 109 definierte Kurvenbahn derart geführt, dass eine gleichmäßige translatorische Bewegung in Öffnungs- oder Schließrichtung entsteht. Die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 beschreiben den gleichen Weg, so dass nach einem Erreichen der Offen-Stellung das Verschlusselement 101 mit einem Handgriff entnommen werden kann.By a pivoting movement of the rotary closure 107 by 90 ° degrees, a linear locking of the closure element 101 takes place simultaneously at four points. The locking slides 105-1, 105-2, 105-3 and 105-4 are guided over the cam track defined by the groove 109 such that a uniform translational movement in the opening or closing direction is formed. The locking slides 105-1, 105-2, 105-3 and 105-4 describe the same way, so that after reaching the open position, the closure element 101 can be removed with a handle.

Fig. 4B zeigt eine weitere Rückansicht des Verschlusselementes 101 mit den Verriegelungsschiebern 105-1, 105-2, 105-3 und 105-4 in der offenen Position. In der offenen Position werden die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 nach Innen gezogen und der elastische Federring 115 komprimiert sich wellenartig. Die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 sind durch kreuzförmige Verstärkungsrippen stabilisiert. Fig. 4B shows a further rear view of the closure element 101 with the locking slides 105-1, 105-2, 105-3 and 105-4 in the open position. In the open position, the locking slides 105-1, 105-2, 105-3 and 105-4 are pulled inwards and the elastic spring ring 115 compresses in a wave-like manner. The locking slides 105-1, 105-2, 105-3 and 105-4 are stabilized by cross-shaped reinforcing ribs.

Fig. 5A und 5B zeigen weitere perspektivische Ansichten des Verschlusselementes 101. Durch Drehen des Drehverschlusses 107 bewegen sich die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4, so dass das Verschlusselement verriegelt werden kann. An der Rückseite des Verschlusselementes 101 ist jeweils eine linke und rechte Seitenwand 129 gebildet, durch die das Verschlusselement 101 beim Einsetzen in die Wartungsöffnung 103 geführt werden kann. Figs. 5A and 5B show further perspective views of the closure element 101. By rotating the rotary closure 107 to move the locking slide 105-1, 105-2, 105-3 and 105-4, so that the closure element can be locked. On the rear side of the closure element 101, a left and right side wall 129 are respectively formed, through which the closure element 101 can be guided during insertion into the maintenance opening 103.

Die Verriegelungsschieber 105-1, 105-2, 105-3 und 105-4 weisen eine flache, im Querschnitt rechteckige Form auf, so dass diese raumsparend in das Verschlusselement 101 integriert werden können. Das Verschlusselement 101 kann mit einer nicht gezeigten Abdeckkappe bedeckt werden, die eine Öffnung für den Drehverschluss 107 umfasst. Dadurch kann die Mechanik im Inneren des Verschlusselementes 101 vor Beschädigungen geschützt werden.The locking slides 105-1, 105-2, 105-3 and 105-4 have a flat, rectangular in cross-section shape, so that this space-saving integrated into the closure element 101 can be. The closure element 101 may be covered with a cover, not shown, which comprises an opening for the rotary closure 107. As a result, the mechanism inside the closure element 101 can be protected from damage.
