Der in Fig. 1 und 2 dargestellte Stiftspitzer 1 umfasst einen näherungsweise quaderförmigen Spitzerkörper 2 aus einem vergleichsweise harten Kunststoffmaterial. Der Spitzerkörper 2 weist an einer Oberseite 3 eine Messerhalterung 4 auf, in der ein Schälmesser 5 etwa parallel zu der Oberseite 3 einliegt. Das Schälmesser 5 ist durch eine (nicht näher dargestellte) Befestigungsschraube in der Messerhalterung 4 fixiert. An einer Vorderseite 6 des Spitzerkörpers 2 mündet ein nach Art einer Bohrung innerhalb des Spitzerkörpers 2 ausgebildeter Stiftführungskanal 7, in den ein (nicht näher dargestellter) Stift für den Spitzvorgang eingeschoben werden kann. Im Bereich einer Einführöffnung 8 weist der Stiftführungskanal 7 zunächst einen zylindrischen Abschnitt 9 auf. An das von der Einführöffnung 8 abgewandte Ende dieses Abschnitts 9 schließt ein konischer Abschnitt an, der im Folgenden als Spitzkonus 10 bezeichnet ist.The in Fig. 1 and 2 illustrated pencil sharpener 1 comprises an approximately cuboidal sharpener body 2 made of a comparatively hard plastic material. The sharpener body 2 has a knife holder 4 on an upper side 3, in which a peeling knife 5 rests approximately parallel to the upper side 3. The paring knife 5 is fixed in the knife holder 4 by a fastening screw (not shown in more detail). At a front side 6 of the sharpener body 2 opens a trained in the manner of a bore within the sharpener body 2 pin guide channel 7, in which a (not shown) pin can be inserted for the sharpening process. In the region of an insertion opening 8, the pin guide channel 7 initially has a cylindrical section 9. At the remote from the insertion opening 8 The end of this section 9 is followed by a conical section, which is referred to below as a pointed cone 10.

Der Stiftführungskanal 7 ist bezüglich seiner Achse 11 schräg zu den Grundflächen des Spitzerkörpers 2 ausgerichtet, so dass die Wand des Stiftführungskanals 7 im Bereich des Spitzkonus 10 etwa die Oberseite 3 des Spitzerkörpers 2 tangiert. Im Bereich dieser Tangente ist der Stiftführungskanal 7 über einen Schneidschlitz 12, in den das Schälmesser 5 mit einer Schneidkante hineinsteht, zur Oberseite 3 hin geöffnet. Der Schneidschlitz 12 dient in bekannter Weise zum Auswurf der beim Spitzvorgang abgeschälten Späne des Stiftmaterials.The pin guide channel 7 is aligned with respect to its axis 11 obliquely to the base surfaces of the sharpener body 2, so that the wall of the pin guide channel 7 in the region of the pointed cone 10 about the top 3 of the sharpener body 2 is tangent. In the region of this tangent, the pin guide channel 7 is opened to the upper side 3 via a cutting slot 12, into which the peeling knife 5 projects with a cutting edge. The cutting slot 12 is used in a known manner for ejecting the peeled off during the sharpening chips of the pin material.

An zwei einander gegenüberliegenden Seitenflächen 13 ist der Spitzerkörper 2 jeweils mit einer Griffmulde 14 versehen, deren bezüglich des Spitzerkörpers 2 nach innen gewölbte Fläche eine Grifffläche 15 definiert. Die Griffmulden 14 bzw. Griffflächen 15 sind als Anlage für Daumen und Zeigefinger einer den Spitzerkörper 2 beim Spitzvorgang haltenden Hand vorgesehen und dienen dabei insbesondere der besseren Greifbarkeit des Spitzerkörpers 2. Um diese Greifbarkeit noch weiter zu verbessern, trägt der Spitzerkörper 2 im Bereich einer jeden Grifffläche 15 vier stäbchen- oder stegförmige Griffkissen 16. Jedes Griffkissen 16 besteht aus einem gegenüber dem Material des Spitzerkörpers 2 weicheren und insbesondere elastischen Kunststoffmaterial, das beim manuellen Festhalten des Spitzerkörpers 2 zwischen Daumen und Zeigefinger nach Art eines Kissens nachgibt . Die Griffkissen 16 sind hierbei teilweise in das Material des Spitzerkörpers 2 eingebettet und stehen nach Art von parallelen Stegen über die Oberfläche des Spitzerkörpers 2 hervor. Hierdurch ist im Bereich der Grifffläche 15 durch die Griffkissen 16 eine weiche Rippenstruktur gebildet.At two opposite side surfaces 13 of the sharpener body 2 is each provided with a recessed grip 14, whose respect to the sharpener body 2 inwardly curved surface defines a gripping surface 15. The grip recesses 14 and gripping surfaces 15 are provided as an attachment for the thumb and index finger of the sharpener body 2 during the sharpening process hand and serve in particular the better tangibility of the sharpener body 2. To further improve this tangibility, the sharpener body 2 carries in the area of each Grip surface 15 four rod-shaped or web-shaped handle pad 16. Each handle pad 16 consists of a relation to the material of the sharpener body 2 softer and especially elastic plastic material which yields when manually holding the sharpener body 2 between the thumb and forefinger in the manner of a pillow. The grip pads 16 are in this case partially embedded in the material of the sharpener body 2 and protrude in the manner of parallel webs over the surface of the sharpener body 2. As a result, in the region of the gripping surface 15, a soft rib structure is formed by the grip cushions 16.

Der Spitzerkörper 2 ist zusammen mit den eingebetteten Griffkissen 16 als einstückiges Teil in einem Zweikomponenten-Spritzgussverfahren hergestellt.The sharpener body 2, together with the embedded handle pads 16, is manufactured as a one-piece part in a two-component injection molding process.

Anstelle von stäbchen- oder stegförmigen Griffkissen 16 können auch noppenförmige Griffkissen vorgesehen sein.Instead of rod-shaped or web-shaped grip pad 16, knob-shaped handle pads may also be provided.

Die erfindungsgemäß mit Griffkissen 16 versehenen Griffflächen 15 können bei einem beliebig geformten Spitzerkörper 2 eingesetzt sein. Eine vor allem hinsichtlich der äußeren Formgebung des Spitzerkörpers 2 von dem vorstehend beschriebenen Spitzspitzer 1 abweichende weitere Ausführungsform des Stiftspitzers 1 ist in den Fig. 3 und 4 gezeigt. Diese Ausführungsform des Stiftspitzers 1 ist wiederum mit zwei das Schälmesser 5 beidseitig flankierenden Griffflächen 15 versehen, denen im Unterschied zu dem vorstehend beschriebenen Ausführungsbeispiel jeweils ein einziges Griffkissen 16 zugeordnet ist. Dieses Griffkissen 16 füllt die Grifffläche 15 vollständig aus. Mit anderen Worten bildet die von dem Griffkissen 16 eingenommene Fläche die Grifffläche 15. Das oder jedes Griffkissen 16 kann, wie in Fig. 4 angedeutet, wiederum eine Mulde ausbilden. Alternativ kann das Griffkissen 16 aber auch plan mit der umgebenden Außenwand des Spitzerkörpers 2 abschließen.The gripping surfaces 15 provided according to the invention with grip pads 16 can be used in an arbitrarily shaped sharpener body 2.
