Description
Die Erfindung betrifft eine Vorrichtung mit den im Oberbegriff des Anspruches 1
aufgeführten Merkmalen. Wesentlicher Bestandteil zu spitzender Stifte ist deren
zentrale Mine, die zur Vermeidung einer Beschmutzung der Benutzerhand von
einem schälbaren Werkstoff umhüllt ist. Dieser Werkstoff besteht herkömmlich
meistenteils aus schälbarem Holz, aus einer Papierhülse od.dgl. Der Minendurchmesser
derartiger Stifte ist entsprechend dem Verwendungszweck unterschiedlich
groß. Die Stiftmine unterliegt bei der Stiftbenutzung einem permanenten
Verschleiss, der eine Abstumpfung der Minenspitze verursacht. Das verändert
das Schriftbild und zur Regenerierung der Stiftspitze wird der Stift mittels des Spitzers
in regelmäßigen Zeitabständen gespitzt. Es ist daher für den Benutzer des
Stiftes wünschenswert, den Stift- bzw. Minenspitzer permanent in leicht greifbarer
Nähe zu haben.The invention relates to a device with the preamble of
Zum Spitzen üblicherweise verwendete Spitzer sind einfache Massenartikel in unterschiedlicher Ausführung. Hinsichtlich eines Gestaltungsmerkmals gleichen sich derartige Spitzer. Sie enthalten nämlich ein das konische Ende ihres Stiftführungskanals flankierendes Schälmesser zum konischen Abschälen des zu spitzenden Stiftendes. Dieses Spitzen dient in erster Linie zur wunschgemäßen Schärfung bzw. Formung der im Mantelbereich zum Schreibende hin sich konisch verjüngenden Mine.Sharpener commonly used for sharpening are simple bulk items in different versions. Same in terms of a design feature such sharpener. They contain a conical end of their pin guide channel flanking peeling knife for conical peeling of the to be sharpened Pin end. This sharpening serves primarily to the desired Sharpening or shaping of the conical area towards the end of the writing rejuvenating mine.
Der Erfindung liegt die Aufgabe zugrunde, eine universal verwendbare Vorrichtung
zu schaffen, die es dem Stiftbenutzer ermöglicht, den zur regelmäßig erforderlichen
Regenerierung der Stiftspitze erforderlichen Spitzer jeweils griffnah verfügbar
zu haben. Diese Aufgabe wird durch Anspruch 1 gelöst. The invention has for its object a universally usable device
to create, which enables the pen user to do the regular necessary
Regeneration of the pen tip required sharpener available at hand
to have. This object is solved by
Die erfindungsgemäße Vorrichtung ist ein Steckadapter, der einfach, jedoch verliersicher auf das für die bestimmungsgemäße Stiftbenutzung nicht erforderliche Rückende des Stiftes aufsteckbar bzw. aufsetzbar ist und dort den Spitzer unverlierbar, jedoch zu seiner Inbenutzungnahme lösbar hält. Für einerseits die verliersichere Haftung der Vorrichtung am rückwärtigen Stiftende und andererseits auch für ihre leichte Lösbarkeit dient zunächst die gummielastische Kontraktionsfähigkeit des Vorrichtungswerkstoffes am Aufsetzende und dessen die Haftwirkung begünstigender Reibungskoeffizient. Dadurch ist es z.B. der zum Aufsetzen auf das rückwärtige Stiftende vorgesehenen Kappe bzw. Hülse auch leicht möglich, sich unterschiedlichen Umfangsformen des Stiftes selbsttätig anzupassen. Es ist nämlich üblich, Stiften nicht nur eine zylindrische Umfangsform zu geben. Auch Schaftquerschnitte in Form meist eines gleichseitigen Sechsecks oder auch elliptische Querschnittsformen sind üblich und andere, auch unregelmäßige Querschnittsformen sind häufig anzutreffen. Die erfindungsgemäße Vorrichtung soll möglichst unabhängig von der Querschnittsform des Stiftschaftes anwendbar sein und auch das ermöglicht die gummiähnliche Elastizität und Kontraktionsfähigkeit des Vorrichtungswerkstoffes.The device according to the invention is a plug-in adapter that is simple, but captive to that which is not necessary for the intended use of the pen Back end of the pin can be plugged on and put on there and the sharpener cannot be lost, however releasably holds for its use. For the one that is captive Adhesion of the device to the rear end of the pin and on the other hand also The elasticity of the contraction serves to ease their solubility of the device material at the end of the attachment and its adhesive effect favorable coefficient of friction. This makes it e.g. the one to put on the cap or sleeve provided at the rear of the pin is also easily possible, to adapt itself to different circumferential shapes of the pen. It is namely, usual to give pins not only a cylindrical peripheral shape. Also Shaft cross sections in the form of mostly an equilateral hexagon or also elliptical Cross-sectional shapes are common and other, even irregular cross-sectional shapes are common. The device according to the invention is intended be applicable as independently of the cross-sectional shape of the stem as possible and that also enables the rubber-like elasticity and contractility of the device material.
Der einerseits leicht lösbaren, jedoch unverlierbaren Fixierung des Spitzers auf dem Haltevorsprung der erfindungsgemäßen Vorrichtung kommt die herkömmliche, in Einsteckrichtung sich verjüngende Konizität des spitzerüblichen Spitzkanalendes entgegen. Dadurch passt der Haltevorsprung grundsätzlich unabhängig von seiner Umfangsform zu einer großen Zahl von gängigen Spitzern. An welcher axialen Position des sich zu seiner Spitze bzw. seinem Steckende hin konisch verjüngenden Spitzkanals der angestrebte Haftschluss zustande kommt, ist unbedeutend. Wesentlich ist nur, dass ein solcher Haftschluss zustande kommt und diesem Zweck ist die gummielastische Konsistenz des Vorrichtungswerkstoffes förderlich. Sie sorgt an der Klemmstelle für den notwendigen Klemm- bzw. Haftungsdruck und macht die angestrebte Haftwirkung weitgehend unabhängig von der Umfangsform des Haltevorsprungs. Durch die segmentartige Aufteilung des Haltevorsprunges lässt sich in einfacher Weise das radiale Federverhalten des Haltevorsprunges beeinflussen und variieren. Die Segmente des Vorsprunges sind wie Spreizbacken eines Spreizspannfutters auf die Mantelflächen des Schälkonus des Stiftführungskanals des Spitzers wirksam und passen sich noch besser unterschiedlichen Formen von Spitzern, insbesondere von deren Spitzkanälen an.The on the one hand easily detachable but captive fixation of the sharpener the retaining projection of the device according to the invention comes with the conventional tapering in the insertion direction of the pointed pointed channel end opposite. As a result, the retaining projection basically fits independently from its circumferential shape to a large number of common sharpener. At which axial position of the conical towards its tip or its plug end rejuvenating Spitz Canal the desired adhesive closure is irrelevant. It is only essential that such a liability is concluded and this is the rubber-elastic consistency of the device material conducive. It ensures the necessary clamping or adhesive pressure at the clamping point and makes the desired adhesive effect largely independent of the circumferential shape of the holding projection. By segmenting the Holding projection can be the radial spring behavior of the Hold tabs affect and vary. The segments of the tab are like expanding jaws of an expanding chuck on the outer surfaces of the peeling cone of the pencil guide channel of the sharpener and adapt even better different forms of sharpener, especially their pointed channels.
Zur weiteren Förderung der Haftwirkung dienen in Unteransprüchen niedergelegte Eigenschaften der Vorrichtung.Subclaims serve to further promote the adhesive effect Characteristics of the device.

Der Stift 1 enthält eine zu seiner Längsachse 2 konzentrische Stiftmine 3, die zur
besseren Greifbarkeit und als Berührungsschutz ebenfalls konzentrisch zur
Längsachse 2 von einem Hüllmantel 4 aus schälbarem Werkstoff, z.B. aus Holz,
Pappe oder einem entsprechenden Kunststoff umgeben ist. Die Spitze 5 der
Stiftmine 3 steht nach vorne aus dem Hüllmantel 4 hinaus. Das vorderseitige
Schreibende 6 des Stiftes 1 verjüngt sich in Richtung auf das vorderseitige Minenende
7 konisch. Zum jeweiligen Spitzen des Schreibendes 6 bzw. des Minenendes
7 dient ein insgesamt mit 8 bezeichneter Handspitzer, wie er als Massenartikel
handelsüblich und hinsichtlich auch seines generellen Funktionsprinzips z.B.
aus DE 3004020 bekannt ist. Ein wesentliches Merkmal dieses hier nur gestrichelt
(Fig. 1) dargestellten Spitzers 8 ist sein Stiftführungskanal 9, der sich in Richtung
auf sein innenliegendes Ende 10 konisch verjüngt. Der Konusmantel 11 des Führungskanals
ist von einem hier nicht näher dargestellten Schälmesser flankiert,
welches den Stiftkonus 12 über seine gesamte axiale Länge spanend formt. Dazu
wird der Stift 1 innerhalb des Gehäuses des stationär gestalteten Spitzers 8 manuell
gedreht.The
Auf das dem Minenende 7 abgewandte rückwärtige Ende 13 des Hüllmantels 4 ist
eine insgesamt mit 14 bezeichnete Haltevorrichtung aufsetzbar. Die Haltevorrichtung
hat auf ihrer in Aufsetzposition der Minenspitze 5 zugewandten Aufsetzseite
15 eine die Stecköffnung 16 umgebende Kappe bzw. Hülse 17 mit in Steckposition
(Fig.1; 4,6 und 7) der Minenspitze 5 zugewandtem Öffnungsrand 18.On the
An ihrer der Aufsetzseite 15 abgewandten Halteseite 19 enthält die Haltevorrichtung
einen Haltevorsprung 20 zum lösbar haftenden Eingriff in den Stiftführungskanal
9 des Spitzers 8. Die Haltevorrichtung ist ein einstückiger Formkörper 21
(Fig. 2,3). Der Haltevorsprung 20 enthält vier nach Art der Stäbe eines Liktorenbündels
nebeneinander positionierte, gleich große und vorzugsweise gleich gestaltete
Vorsprungsegmente 22. Sie sind radial zur Vorstehrichtung 23 der Längsachse
2 des Formkörpers 21 voneinander beabstandet (Abstandsspalte 27 in
Fig. 1 bis 3) und gleich groß sowie gleich gestaltet. In auf das der Minenspitze 5
zugeordnete Schreibende 6 aufgesetzter Position umgibt die Aufsetzkappe 17
einen Hohlraum, der die freiliegende Minenspitze 5 gegenüber der Umgebungsatmosphäre
abdichte. Dadurch gelangen keine oder weniger Ausdünstungen
der Minenspitze 5 an die Umgebungsluft. Außerdem ist dadurch die Minenspitze
5 gegen Austrocknung abgeschirmt. Der Außenumfang der Vorsprungsegmente
22 bildet Teile etwa eines die Längsachse 2 des Formkörpers 21 und damit
des Haltevorsprunges 20 konzentrisch umgebenden Umfangsmantels, insbesondere
Zylindermantels.The holding device contains on its

Öffnungsseite vom Öffnungsrand 18 umgeben.The
Ein Weiterbildungsmerkmal besteht darin, dass der Werkstoff des Formkörpers 21
der eines Radiergummis sein kann. Damit lässt sich der Formkörper 21 außerhalb
seiner Haltefunktion noch als Radiergummi verwenden. Diese zusätzliche oder
wenigstens notweise einsetzbare Radierfunktion kann der Haltekörper ohne Beeinträchtigung
seiner Haltefunktion insbesondere dann in befriedigender Weise
erfüllen, wenn er nicht zu intensiv und nicht zu häufig zum Radieren eingesetzt
wird. A further development feature is that the material of the molded
