Abstract
Description
Schreibdocht aus gesintertem Kunststoff Schreibdochte werden u.a. aus gesinterten Kunststoffen hergestellt. Je nach Art und Dauer eines Sintervorganges sowie auch nach Art und Typ des verwendeten Kunststoffmaterials kann das Sinterprodukt unterschiedliche Härtegrade aufweisen.Writing wicks made of sintered plastic Writing wicks are among others made from sintered plastics. Depending on the type and duration of a sintering process as well as the type and type of plastic material used, the sintered product have different degrees of hardness.
Unterschiedliche Härtegrade werden vielfach auch für die Schreibspitzen (Schreibflächen) solcher Art ausgesinterter Schreibdochte gefordert. Dabei sollte die Härte des Dochtschaftes im allgemeinen größer sein als die der Schreibfläche. Das umgekehrte Verhältnis ist grundsätzlich aber auch möglich.Different degrees of hardness are often required for the writing tips (writing surfaces) of this type of sintered writing wicks. The hardness of the wick should generally be greater than that of the writing surface. The reverse relationship is but also possible in principle.
Dennoch: Bisher bestanden Schreibdochte durchweg aus einheitlich gesintertem Material, nämlich von vorn bis hinten mit gleichem Härtegrad.Nevertheless: So far, writing wicks consisted entirely of uniformly sintered material Material, namely from front to back with the same degree of hardness.
Der Erfindung liegt die Aufgabe zugrunde, den Vorteil unterschiedlicher Härtegrade in verschiedenen Teilen eines Schreibdochtes zu verwirklichen. Die Erfindung löst diese Aufgabe einfach und überzeugend. Sie besteht darin, daß ihre Schreibfläche aus einem Material besteht, das gegenüber dem sonstigen Dochtmaterial unterschiedliche Härtegrade im gesinterten Zustand besitzt. Erfindungsgemäß kann die Schreibfläche härter sein als die übrigen Dochtpartien, sie kann aber auch weicher als die übrigen Dochtpartien eingestellt werden.The invention is based on the advantage of different To realize degrees of hardness in different parts of a writing wick. The invention solves this task simply and convincingly. It consists in its writing surface consists of a material that is different from the other wick material Has degrees of hardness in the sintered state. According to the invention, the writing surface be harder than the other parts of the wick, but it can also be softer than the rest Wick sections are set.
Es liegt auch im Rahmen dieser Erfindung, wenn für die gesamte Spitze des Dochtes ein aus dem zum sonstigen Dochtmaterial unterschiedliche Härtegrade aufweisender Kunststoff verwendet wird. Es ist aber auch im Rahmen der Erfindung möglich, daß lediglich die äußere Schale der Schreibspitze aus dem zum sonstigen Dochtmaterial unterschiedliche. Härtegrade aufweisenden Kunststoff besteht.It is also within the scope of this invention if for the entire tip The wick has a different degree of hardness than the other wick material comprising plastic is used. But it is also within the scope of the invention possible that only the outer shell the nib from the different from the other wick material. Plastic with degrees of hardness consists.
An Hand beiliegender Skizze sei die Erfindung noch einmal in beispielhafter Ausführungsform erläutert.On the basis of the enclosed sketch, the invention is once again exemplified Embodiment explained.
Ein Schreibdocht nach Figur 1 besteht aus einheitlichem Kunststoffmaterial, das im Bereich der Schreibspitze (1) mit einem anderen Härtegrad ausgesintert ist als im Bereich des Schaftes (2). Dabei kann nach Bedarf die Spitze (1) härter oder weicher sein als der Schaft (2).A writing wick according to Figure 1 consists of a uniform plastic material, which is sintered out with a different degree of hardness in the area of the writing tip (1) than in the area of the shaft (2). The tip (1) can be harder or harder as required be softer than the shaft (2).
Darüber hinaus ist es möglich, daß unterschiedliches Material gesintert wird, und zwar einmal für die Schreibspitze (1) und zum anderen für den Schaft (2). Figur 2 stellt die besondere Ausführungsform der Erfindung dar, wobei lediglich eine Schale (3) um die Schreibspitze (4) mit anderem Härtegrad gesintert ist als der übrige Docht (5).In addition, it is possible for different materials to be sintered is, once for the writing tip (1) and on the other hand for the shaft (2). Figure 2 shows the particular embodiment of the invention, with only a shell (3) around the nib (4) is sintered with a different degree of hardness than the remaining wick (5).
