- the three wedge surfaces 18, 20 and 22 of the clamping ring 42 and the corresponding wedge surfaces 44, 46 and 48 of the cap sleeve 10 can be seen.
- the rotation of the clamping ring 42 relative to the cap sleeve 10 consequently, its inner diameter is reduced. This leads to a clamping and thus also to an axial tight fit of the cap 68 on the housing 32.
- the rotation of the clamping ring 42 is effected by the frictional engagement with the housing 32.
- the cap 68 can be put on in the usual way and fix with only a slight turn ( ⁇ 120 °).
Description
Die vorliegende Erfindung betrifft eine Kappe für ein Schreib-, Zeichen- oder Malgerät mit einer Kappenhülse und einem Klemmring gemäß dem Oberbegriff von Anspruch 1.The present invention relates to a cap for a writing, drawing or painting device with a cap sleeve and a clamping ring according to the preamble of claim 1.
Viele Schreibgeräte mit abnehmbarer Kappe, insbesondere Füllfederhalter, besitzen eine aufschraubbare Kappe, welche zwar eine sichere Verbindung zwischen dem Gehäuse des Schreibgerätes und der Kappe gewährleistet, jedoch umständlich und daher nicht schnell einsetzbar ist.Many writing instruments with removable cap, especially fountain pen, have a screw cap, which although a secure connection between the housing of the writing instrument and the cap ensures, but cumbersome and therefore can not be used quickly.
Aus der
Der Erfindung liegt somit die Aufgabe zugrunde, die gattungsgemäße Kappe derart weitenzubilden, daß eine sichere Verbindung zwischen dem Gehäuse eines Schreib-, Zeichen- oder Malgerätes und der Kappe bei gleichzeitig einfacher Handhabung und Herstellung gewährleistet ist.The invention is therefore the object of the generic cap educate such that a secure connection between the housing of a writing, drawing or painting device and the cap is ensured at the same time easy to use and manufacture.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß auf der Außenumfangsfläche des Klemmrings wenigstens eine in Umfangsrichtung radial ansteigende Keilfläche und auf der Innenumfangsfläche der Kappenhülse eine entsprechende Anzahl von ebensolchen Keilflächen angeordnet sind, und die Steigungen der nach dem Einsetzen des Klemmrings in die Kappenhülse sich gegenüberliegenden Keilflächen gleich sind.According to the invention this object is achieved in that on the outer peripheral surface of the clamping ring at least one circumferentially radially increasing wedge surface and on the inner peripheral surface of the cap sleeve a corresponding number of just such wedge surfaces are arranged, and the slopes of the after insertion of the clamping ring in the cap sleeve opposite wedge surfaces are the same.
Insbesondere kann dabei vorgesehen sein, daß die Innenumfangsfläche des Klemmrings derart gestaltet ist, daß durch Aufsetzen der Kappe auf das Gehäuse ein Reib- oder Formschluß zwischen dem Klemmring und dem Gehäuse resultiert.In particular, it can be provided that the inner peripheral surface of the clamping ring is designed such that a frictional or positive connection between the clamping ring and the housing results by placing the cap on the housing.
Weiterhin kann vorgesehen sein, daß die Innenumfangsfläche der Kappenhülse sowie die Außenumfanesfläche des Klemmrings derart gestaltet sind, daß durch Aufsetzen der Kappe auf das Gehäuse des Schreib-, Zeichen- oder Malgerätes und eine nachfolgende relative axiale Drehung zwischen der Kappe und dem Gehäuse ein Reibschluß zwischen der Kappenhülse und dem Klemmring resultiert.Furthermore, it can be provided that the inner peripheral surface of the cap sleeve and the Außenumfanesfläche the clamping ring are designed such that a frictional engagement between by placing the cap on the housing of the writing, drawing or painting device and a subsequent relative axial rotation between the cap and the housing the cap sleeve and the clamping ring results.
Schließlich kann vorgesehen sein, daß die Kappe derart gestaltet ist, daß sie dichtend auf das Gehäuse aufsetzbar ist.Finally, it can be provided that the cap is designed such that it can be placed sealingly on the housing.
Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß durch einen Klemmring, der durch Drehen der Kappe seine Funktion entfaltet, die Herstellung einer sicheren Verbindung auf einfache Weise ermöglicht wird. Die Kappe läßt sich in gewohnter Weise aufsetzen und mit einer nur geringen Drehung (< 120 °) fixieren. Durch einen separaten Klemmring ist kein radial orientiertes Einsuchen, wie bei einem Bajonettverschluß, erforderlich.The invention is based on the surprising finding that the production of a secure connection is made possible in a simple manner by a clamping ring which unfolds its function by turning the cap. The cap can be put on in the usual way and fixed with only a slight turn (<120 °). By a separate clamping ring is no radially oriented search, as in a bayonet lock required.
Außerdem entfällt bei der Herstellung der Kappe das Entspindeln, wie es bei einem Gewinde für eine Schraubverbindung erforderlich wäre.In addition, eliminates in the manufacture of the cap, the unwinding, as would be required for a thread for a screw.
