Description

Die Erfindung betrifft ein Schreibgerät nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a writing instrument according to the preamble of patent claim 1.

Es sind unterschiedliche Schreibgeräte, wie beispielsweise Füllfederhalter, Kugelschreiber etc. bekannt, die einen Halterschaft und ein damit verschraubtes Vorderteil mit einer Schreibspitze aufweisen. Vorderteil und Halterschaft sind auseinanderschraubbar ausgebildet, um Tinte oder Tusche auffüllen oder Tintenpatronen oder eine Schreibmine ersetzen zu können. Der Halterschaft ist aus diesem Grund an seinem offenen Ende mit einem Innengewinde und das Vorderteil an seinem von der Schreibspitze abgewandten Ende mit einem Außengewinde versehen.Different writing instruments, such as fountain pens, ballpoint pens, etc., are known which have a holder shaft and a front part screwed to it with a writing tip. The front part and holder shaft can be screwed apart so that ink or ink can be refilled or ink cartridges or a writing refill can be replaced. For this reason, the holder shaft is provided with an internal thread at its open end and the front part with an external thread at its end facing away from the writing tip.

Bei einigen Schreibgeräten ist die Außenfläche mit einer Musterung, etwa in Form von farblichen oder reliefartigen Gestaltungen versehen, die sich über die Außenflächen von Halterschaft und Vorderteil ziehen. Beispiele dafür sind Rillen oder farbige Striche, die in Längsrichtung über die Oberfläche des Schreibgerätes verlaufen. Ebenso gibt es Schreibgeräte, die im Querschnitt zur Längsachse nicht exakt kreisförmig sind, sondern beispielweise einen ovalen oder polygonalen Querschnitt haben. Bei den genannten Gestaltungen ergibt sich der Nachteil, daß nach dem Zusammenschrauben von Halterschaft und Vorderteil diese in ihrer Schließstellung in der Regel nicht passend zueinander ausgerichtet sind. Die Oberflächengestaltungen von Halterschaft und Vorderteil gehen daher in der Regel nicht passend ineinander über, sondern sind gegeneinander verdreht, wenn sie vom Benutzer nicht genau zueinander eingestellt werden. Die exakte Einstellung beider Teile zueinander ist für den Benutzer zum einen mühsam, und zum anderen ist dabei nicht sichergestellt, daß in der nach der Oberflächgestaltung richtigen Einstellung beider Teile eine feste und sichere Verschlußstellung der Schraubverbindung gewährleistet wird.With some writing instruments, the outer surface is provided with a pattern, for example in the form of colored or relief-like designs, which extend over the outer surfaces of the holder shaft and front part. Examples of this are grooves or colored lines that run longitudinally over the surface of the writing instrument. There are also writing implements that are not exactly circular in cross-section to the longitudinal axis, but have, for example, an oval or polygonal cross-section. With the designs mentioned, there is the disadvantage that after screwing together the holder shaft and front part, they are usually not aligned with each other in their closed position. The surface designs of the holder shaft and front part therefore do not usually blend into one another, but are twisted against one another if they are not set exactly by the user. The exact adjustment of the two parts to each other is laborious for the user, on the one hand, and on the other hand it is not ensured that a correct and secure locking position of the screw connection is ensured in the correct setting of both parts after the surface design.

Es ist Aufgabe der Erfindung, ein aus zwei miteinander zu verschraubenden Teilen bestehendes Schreibgerät zu schaffen, bei dem beide Teile nach dem Zusammenschrauben eine Schließposition mit vorgegebener Drehstellung zueinander einnehmen.It is an object of the invention to provide a writing instrument consisting of two parts to be screwed together, in which both parts assume a closed position with a predetermined rotational position relative to one another after screwing together.

Zur Lösung dieser Aufgabe dienen die kennzeichnenden Merkmale des Patentanspruchs 1 in Verbindung mit dessen Oberbegriff. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.To solve this problem, the characterizing features of claim 1 serve in conjunction with its preamble. Advantageous refinements are the subject of the dependent claims.

Erfindungsgemäß sind in dem Halterschaft erste Arretiermittel vorgesehen, die bei Erreichen der Schließposition der Schraubverbindung in zweite Arretiermittel am Vorderteil eingreifen und das Vorderteil in der vorgegebenen Drehstellung am Halterschaft lösbar arretieren und so gegen gegen weiteres Verdrehen sichern. Die ersten und zweiten Arretiermittel sind so zueinander angeordnet, daß Vorderteil und Halterschaft beim Zusammenschrauben in der vorgegebenen Drehstellung einrasten, wodurch gewährleistet werden kann, daß Vorderteil und Halterschaft keinesfalls verdreht zueinander stehen, sondern die vorgegebene Schließposition einnehmen, so daß aufeinander abgestimmte Oberflächengestaltungen beider Teile passend zueinander liegen und stetig ineinander übergehen.According to the invention, first locking means are provided in the holder shaft, which engage in the second locking means on the front part when the screw connection reaches the closed position and releasably lock the front part in the predetermined rotational position on the holder shaft and thus secure against further rotation. The first and second locking means are arranged in such a way that the front part and holder shaft engage when screwed together in the specified rotational position, which can ensure that the front part and holder shaft are in no way rotated relative to one another, but instead assume the specified closed position, so that coordinated surface configurations of both parts fit lie to each other and merge continuously.

In einer vorteilhaften Ausgestaltung werden die ersten Arretiermittel durch wenigstens einen an der Innenfläche oder dem Innengewinde des Halterschaftes vorgesehenen Vorsprung und die zweiten Arretiermittel durch wenigstens eine an der Außenfläche oder dem Außengewinde des Vorderteils vorgesehene Ausnehmung gebildet. Beim Zusammenschrauben beider Schreibgerätteile gleitet jeder Vorsprung bei Erreichen der vorgegebenen Schließposition in eine zugeordnete Ausnehmung und verhindert so ein weiteres Verdrehen beider Teile gegeneinander. Grundsätzlich können natürlich auch umgekehrt die ersten Arretiermittel durch Ausnehmungen und die zweiten Arretiermittel durch Vorsprünge gebildet werden. Die zusammenwirkenden Ausnehmungen bzw. Vorsprünge können außerhalb der Gewindebereiche des Vorderteils bzw. des Halterschafts oder jeweils an den Gewindeflanken angeordnet sein. Die Vorsprünge können in bezüglich der Längsachse des Schreibgerätes axiale oder radiale Ausnehmungen eingreifen.In an advantageous embodiment, the first locking means are formed by at least one projection provided on the inner surface or the internal thread of the holder shaft and the second locking means by at least one recess provided on the outer surface or the external thread of the front part. When the two parts of the writing instrument are screwed together, each projection slides into an associated recess when the predetermined closed position is reached, and thus prevents the two parts from rotating further. In principle, of course, the first locking means can of course also be formed by recesses and the second locking means by projections. The cooperating recesses or projections can be arranged outside the thread areas of the front part or the holder shaft or on the thread flanks in each case. The projections can engage in axial or radial recesses with respect to the longitudinal axis of the writing instrument.

In einer weiteren vorteilhaften Ausgestaltung ist jeder Vorsprung als eine an der Innenfläche in Längsrichtung des Halterschaftes verlaufende Rippe ausgebildet, die von dem offenen Ende des Halterschaftes aus hinter dem Innengewinde beginnt und in das Innere verläuft. Entsprechend dazu haben im vorderen Rand der das Außengewinde tragenden zylindrischen Außenfläche des Vorderteils die Ausnehmungen die Form von axialen Einschnitten.In a further advantageous embodiment, each projection is designed as a rib running on the inner surface in the longitudinal direction of the holder shaft, which begins from the open end of the holder shaft behind the internal thread and extends into the interior. Correspondingly, in the front edge of the cylindrical outer surface of the front part carrying the external thread, the recesses have the shape of axial incisions.

In einer vorteilhaften Ausgestaltung sind wenigstens zwei Rippen an der Innenfläche des Halterschaftes und wenigstens zwei Einschnitte im äußeren Rand der zylindrischen Außenfläche des Vorderteils vorgesehen.In an advantageous embodiment, at least two ribs are provided on the inner surface of the holder shaft and at least two incisions in the outer edge of the cylindrical outer surface of the front part.

In einer weiteren vorteilhaften Ausgestaltung ist der vordere Rand der Außenfläche des Vorderteils von einem Einschnitt zum nächsten in Gangrichtung des Außengewindes axial in der Weise ansteigend ausgebildet, daß jeder Einschnitt eine hohe seitliche Begrenzung und eine niedrige seitliche Begrenzung, welche durch eine niedriger als die hohe seitliche Begrenzung geformte axiale Erhöhung gebildet wird, aufweist. Dadurch wird erreicht, daß jeder Vorsprung bei Erreichen der Schließposition mit relativ geringem Widerstand über die flach ausgebildete axiale Erhöhung in den Einschnitt gleitet und dann gegen die hohe seitliche Begrenzung anschlägt, was ein weiteres Einschrauben des Vorderteils über die Schließposition hinaus verhindert. Auf der anderen Seite wird der Vorsprung durch die axiale Erhöhung in dem Einschnitt festgehalten, so daß zum Abschrauben des Vorderteils vom Halterschaft ein gewisser Widerstand überwunden werden muß, damit der Vorsprung über die axiale Erhöhung aus dem Einschnitt herausgleitet und so die Arretierung gelöst wird.In a further advantageous embodiment, the front edge of the outer surface of the front part is axially increasing from one incision to the next in the direction of the external thread in such a way that each incision has a high lateral boundary and a low lateral boundary, which is characterized by a lower than the high lateral Limit shaped axial Increase is formed. It is thereby achieved that each projection slides into the incision with relatively little resistance when the closing position is reached, and then strikes against the high lateral limitation, which prevents the front part from being screwed in further beyond the closing position. On the other hand, the projection is held in the incision by the axial elevation, so that a certain resistance has to be overcome to unscrew the front part from the holder shaft so that the projection slides out of the incision via the axial elevation and so the locking is released.

Die Ausgestaltung des Halterschafts mit wenigstens zwei in seinem Inneraum an der Innenfläche verlaufenden Rippen hat den weiteren Vorteil, daß Einsätze, wie etwa Tintenbehälter, Tintenpatronen, etc., im Innenraum des Halterschaftes durch die Rippen zentriert gehalten werden.The design of the holder shaft with at least two ribs running in its interior on the inner surface has the further advantage that inserts, such as ink containers, ink cartridges, etc., are kept centered in the interior of the holder shaft by the ribs.

Die Erfindung wird im folgenden an Hand eines Ausführungsbeispiels in den Zeichnungen erläutert, in denen:

Figur 1
eine perspektivische, teilweise aufgebrochene Darstellung eines auseinandergeschraubten Schreibgerätes ist;
Figur 2
eine perspektivische Darstellung des von der Schreibspitze abgewandten Endes des Vorderteils ist; und
Figur 3
eine abgerollte Darstellung des vorderen zylindrischen Endes des Vorderteils aus Figur 2 ist.
The invention is explained below using an exemplary embodiment in the drawings, in which:
Figure 1
is a perspective, partially broken away view of a writing instrument screwed apart;
Figure 2
a perspective view of the end of the front part facing away from the writing tip; and
Figure 3
a rolled up view of the front cylindrical end of the front part of Figure 2.

In Figur 1 ist ein Schreibgerät in Form eines Füllfederhalters mit einem Halterschaft 1 und einem Vorderteil 2 mit Schreibspitze 3 gezeigt. Der Halterschaft 1 ist hohl und weist an seinem offenen Ende an der Innenfläche 12 ein Innengewinde 11 auf. Demgegenüber trägt das Vorderteil 2 an seinem von der Schreibspitze 3 abgewandten Ende ein Außengewinde 21, das auf einer zylindrischen Außenfläche 22 angeordnet ist.FIG. 1 shows a writing instrument in the form of a fountain pen with a holder shaft 1 and a front part 2 with a writing tip 3. The holder shaft 1 is hollow and has an internal thread 11 at its open end on the inner surface 12. In contrast, the front part 2 carries at its from the writing tip 3 opposite end an external thread 21 which is arranged on a cylindrical outer surface 22.

Die ersten Arretiermittel 13, 14 werden in dem Ausführungsbeispiel durch zwei in axialer Richtung verlaufende Rippen gebildet, die an der Innenfläche 12 hinter dem Innengewinde 11 beginnen und an der Innenfläche 12 weiter in das Innere des Halterschaftes 1 verlaufen. Dementsprechend sind die zweiten Arretiermittel 23, 24 als Einschnitte im vorderen Rand 25, 26 der zylindrischen Außenfläche 22 des Vorderteils 2 gestaltet. Die ersten Arretiermittel 13, 14 und die zweiten Arretiermittel sind derart zueinander angeordnet, daß jede Rippe jeweils in einen zugehörigen Einschnitt gleitet und dort einrastet, wenn das Vorderteil 2 beim Zusammenschrauben seine vorgegeben Schließposition am Halterschaft 1 erreicht. Durch die Arretierung wird erreicht, daß Halterschaft 1 und Vorderteil 2 in ihrer Schließposition eine vorgegebene Drehstellung zueinander haben, so daß Muster oder Oberflächengestaltungen an den Oberflächen 10 und 20 der beiden Teile 1,2 passend zueinander ausgerichtet sind.In the exemplary embodiment, the first locking means 13, 14 are formed by two ribs running in the axial direction, which begin on the inner surface 12 behind the internal thread 11 and continue on the inner surface 12 into the interior of the holder shaft 1. Accordingly, the second locking means 23, 24 are designed as incisions in the front edge 25, 26 of the cylindrical outer surface 22 of the front part 2. The first locking means 13, 14 and the second locking means are arranged with respect to one another such that each rib slides into an associated incision and engages there when the front part 2 reaches its predetermined closed position on the holder shaft 1 when screwed together. The locking ensures that the holder shaft 1 and the front part 2 have a predetermined rotational position in relation to one another in their closed position, so that patterns or surface designs on the surfaces 10 and 20 of the two parts 1, 2 are aligned with one another.

Die Ausbildung der zweiten Arretiermittel 23, 24 ist in den Figuren 2 und 3 genauer dargestellt. Figur 2 zeigt das von der Schreibspitze abgewandte Ende des Vorderteils 2, das eine zylindrische Außenfläche 22 mit einem Außengewinde 21 aufweist. Die zweiten Arretiermittel 23, 24 haben die Form von axialen Einschnitten im vorderen Rand 25, 26 der zylindrischen Außenfläche 22. Der vordere Rand 25, 26 ist so geformt, daß er ausgehend von einem Einschnitt 23 in Gangrichtung der Schraubverbindung zunächst eine axiale Erhöhung aufweist, die eine flache seitliche Begrenzung 23' bildet, und anschließend in dem Bereich 26 des Randes zum nächsten Einschnitt 24 hin ansteigt, so daß dort eine erhöhte seitliche Begrenzung 24' gebildet wird. Entsprechend steigt auch der Randbereich 25 zwischen den beiden Einschnitten 23, 24 an. Diese Ausbildung der Einschnitte und des vorderen Randes ist in Figur 3 zu erkennen, in der der vordere Teil der zylindrischen Außenfläche 22 an der seitlichen Begrenzung 23' aufgeschnitten und abgerollt dargestellt ist.The design of the second locking means 23, 24 is shown in more detail in FIGS. 2 and 3. FIG. 2 shows the end of the front part 2 facing away from the writing tip, which has a cylindrical outer surface 22 with an external thread 21. The second locking means 23, 24 have the form of axial incisions in the front edge 25, 26 of the cylindrical outer surface 22. The front edge 25, 26 is shaped in such a way that, starting from an incision 23 in the thread direction of the screw connection, it initially has an axial elevation, which forms a flat lateral boundary 23 ', and then rises in the region 26 of the edge to the next incision 24, so that an increased lateral boundary 24' is formed there. The edge region 25 between the two incisions 23, 24 also rises accordingly. This formation of the incisions and the front edge can be seen in Figure 3, in which the front Part of the cylindrical outer surface 22 is cut open at the lateral boundary 23 'and shown rolled.

Beim Zusammenschrauben von Vorderteil 2 und Halterschaft 1 nähern sich die Rippen 13, 14 im Halterschaft 1 bei Annäherung an die Schließposition den Einschnitten 23, 24 im vorderen Rand 25, 26 des Vorderteils 2 an und gleiten schließlich über die axialen Erhöhungen in die Einschnitte 23, 24. Die erhöhten seitlichen Begrenzungen 23', 24' bilden dann jeweils einen Anschlag, so daß ein weiteres Verschrauben des Vorderteils 2 am Halterschaft 1 verhindert wird. Die flacher geformten seitlichen Begrenzungen 23'', 24'' bieten den Rippen 13, 14 beim Herausgleiten aus den Einschnitten 23, 24 einen relativ geringeren Widerstand, der einerseits ausreichend ist, um die beiden Teile in ihrer Schließposition festzuhalten, und der andererseits von dem Benutzer beim Losschrauben relativ leicht überwunden werden kann.When the front part 2 and the holder shaft 1 are screwed together, the ribs 13, 14 in the holder shaft 1 approach the incisions 23, 24 in the front edge 25, 26 of the front part 2 when approaching the closed position and finally slide over the axial elevations into the incisions 23, 24. The raised lateral boundaries 23 ', 24' then each form a stop, so that a further screwing of the front part 2 on the holder shaft 1 is prevented. The flatter shaped side boundaries 23 '', 24 '' offer the ribs 13, 14 a relatively lower resistance when sliding out of the incisions 23, 24, which is sufficient on the one hand to hold the two parts in their closed position and on the other hand by the Users can be overcome relatively easily when unscrewing.
