Abstract

A sharpener for lead pencils, colored pencils, cosmetic pencils and the like with an essentially cuboid shaped sharpener housing, in which the longitudinal lateral sides of the sharpener housing are provided with complementary protrusions or recesses that allow fitting together of two sharpeners.

Description

Die Erfindung bezieht sich auf einen Spitzer für Bleistifte, Buntstifte, Kosmetikstifte od.dgl., mit einem im wesentlichen quaderförmigen Spitzergehäuse.The invention relates to a sharpener for pencils, crayons, cosmetic pencils or the like. With an essentially cuboid-shaped sharpener housing.

Derartige Spitzer sind in den unterschiedlichsten Ausführungsformen und Größen bekanntgeworden, wobei Größe der Spitzer, der Neigungswinkel der Spitzermesser sowie die Größe der Ein- und Austrittsöffnung des Spitzerkanals weitgehend von den zu spitzenden Stiften abhängen. Dabei kommt es nicht nur auf den Durchmesser der Stifte an, sondern man verwendet auch unterschiedliche Spitzer bei gleichem Stiftdurchmesser, wenn es sich um Stifte mit unterschiedlich harten Minen handelt. Beispielsweise muß der Spitzer für einen Kosmetikstift mit einer weichen, schmierenden Mine ganz anders ausgelegt sein als ein Spitzer für einen Bleistift mit einer sehr harten Mine.Such sharpeners have become known in a wide variety of designs and sizes, the size of the sharpener, the angle of inclination of the sharpener knives and the size of the inlet and outlet opening of the sharpener channel largely depend on the pins to be sharpened. It is not only the diameter of the pens that is important, but you also use different sharpeners with the same pen diameter when it comes to pens with differently hard leads. For example, the sharpener for a cosmetic pencil with a soft, lubricating lead must be designed quite differently than a sharpener for a pencil with a very hard lead.

Zur gemeinsamen Verwendung auf einem bestimmten Arbeitsgebiet sind bereits Doppelspitzer bekanntgeworden, die meist Einzelspitzer mit unterschiedlichen Spitzerkanälen zum Spitzen unterschiedlich dicker Stifte oder aber auch zum Spitzen wahlweise von Blei- oder Buntstiften umfassen. Diese Mehrfachspitzer sind jedoch von vorneherein auf eine bestimmt Kombination festgelegt, so daß es nicht möglich ist, daß ein Benutzer einen Mehrfachspitzer mit zwei oder mehr bestimmten Einzelspitzern als gemeinsames Bauteil erwerben und benutzen kann.Double sharpeners have already become known for common use in a specific field of work, which mostly comprise single sharpeners with different sharpening channels for sharpening pencils of different thicknesses, but also for sharpening either lead or colored pencils. However, these multiple sharpeners are fixed from the outset to a specific combination, so that it is not possible for a user to acquire and use a multiple sharpener with two or more specific single sharpeners as a common component.

Zur Vermeidung dieser Schwierigkeiten ist erfindungsgemäß ein Spitzer dadurch gekennzeichnet, daß die Längsseitenwände des Spitzergehäuses mit komplementären, ein Zusammenstecken zweier Spitzer ermöglichenden Vorsprüngen bzw. Vertiefungen versehen sind.To avoid these difficulties, a sharpener according to the invention is characterized in that the longitudinal side walls of the sharpener housing are mated with complementary ones two protrusions or recesses enabling sharpener are provided.

Durch die erfindungsgemäße Ausbildung des Spitzergehäuses können wahlweise eine Vielzahl von ansonsten durchaus unterschiedlichen Spitzern zu einer Baueinheit miteinander verbunden werden, wobei mit ganz besonderem Vorteil die Ausbildung der Längsseitenwände so getroffen sein soll, daß die Vorsprünge bzw. Vertiefungen unterschiedlicher Spitzer gruppenweise derart unterschiedlich ausgebildet sind, daß jeweils nur zusammengehörige Spitzer miteinander verbindbar sind. Anders ausgedrückt bedeutet dies, daß beispielsweise Kosmetikspitzer für unterschiedliche Arten von Lippen-, Augenbrauen-oder sonstigen Kosmetikstiften eine zusammengehörige Profilierung der Längsseitenwände aufweisen, jedoch Spitzer für Bleistifte oder Buntstifte eine andere Profilierung, so daß nur die Spitzer für zusammengehörige Stiftgruppen miteinander zu Baueinheiten verbindbar sind. Dabei kann es durchaus auch zweckmäßig sein, die Ausbildung so zu treffen, daß beispielsweise nur Spitzer für Augenbrauenstifte miteinander verbindbar sind, um mehrere Stifte für unterschiedliche Farben miteinander zu verbinden, während Stifte für Lidschatten, Fingernägel, Lippen od.dgl. wieder anders ausgebildet sind, so daß sie nur wieder untereinander verbindbar sind.By designing the sharpener housing according to the invention, a plurality of otherwise quite different sharpeners can optionally be connected to one another, the design of the longitudinal side walls being designed so that the projections or depressions of different sharpeners are designed so differently in groups, with very particular advantage, that only related sharpener can be connected to each other. In other words, this means that, for example, cosmetic sharpeners for different types of lip, eyebrow or other cosmetic pencils have an associated profile of the longitudinal side walls, but pencil sharpeners for pencils or colored pencils have a different profile, so that only the pencil sharpeners for associated pencil groups can be connected to one another to form structural units . It can also be useful to make the training so that, for example, only sharpeners for eyebrow pencils can be connected to one another to connect several pencils for different colors, while pencils for eye shadows, fingernails, lips or the like. are designed differently so that they can only be connected to one another again.

Die Profilierung der Längsseitenwände kann dabei Längs -oder oder Querrippen aufweisen, deren Form und Dicke jeweils der Form und Dicke der Zwischennuten auf der Gegenseite entspricht, so daß zwei Spitzer beim Zusammenstecken klemmend aneinander gehalten werden.The profiling of the longitudinal side walls can have longitudinal or transverse ribs, the shape and thickness of which corresponds to the shape and thickness of the intermediate grooves on the opposite side, so that two sharpener are held together when they are plugged together.

Mit besonderem Vorteil kann dabei weiter vorgesehen sein, daß die Rippen einen trapezförmigen, sich nach außen verbreiternden Querschnitt aufweisen, so daß entweder das Zusammenstecken nur unter Überwindung einer entsprechenden Verformungskraft der Trapezrippen oder bevorzugt durch Parallelverschiebung in Richtung der Längsachsen der Rippen erfolgt und somit das Auseinanderziehen erschwert ist. Dabei kann es auch vorteilhaft sein, in Längsrichtung eine Konizität der Rippen und Zwischennuten vorzusehen, so daß bei dem vorstehend angesprochenen Ineinanderschieben eine Verkeilung auch in der Zusammensteckrichtung stattfindet, so daß eine besonders feste und nicht ohne weiteres wieder sich trennende Baueinheit gebildet wird.With particular advantage, it can further be provided that the ribs have a trapezoidal shape that widens outwards Have cross-section, so that either the plugging together only by overcoming a corresponding deformation force of the trapezoidal ribs or preferably by parallel displacement in the direction of the longitudinal axes of the ribs and thus the pulling apart is difficult. It can also be advantageous to provide a taper of the ribs and intermediate grooves in the longitudinal direction, so that wedging also occurs in the mating direction when the above-mentioned sliding into one another, so that a particularly solid and not easily separable structural unit is formed.

Schließlich liegt es auch im Rahmen der Erfindung, auf einer Längsseitenwand Noppen und auf der anderen Längsseitenwand Aufnahmebuchsen aufzuformen, wie auch schließlich die Ausbildung der gegenüberliegenden Längsseitenwände eines Spitzers analog der Ausbildung sog. Klemmbausteine erfolgen könnte.Finally, it is also within the scope of the invention to form knobs on one longitudinal side wall and receptacle bushings on the other longitudinal side wall, just as finally the formation of the opposite longitudinal side walls of a sharpener could take place analogously to the formation of so-called clamping modules.

Um die erfindungsgemäße Kombinierbarkeit zu mehrere Spitzer umfassenden Baueinheiten auch für Spitzer mit Spanfangdosen auszunützen, können in Weiterbildung der Erfindung verschmälerte, das Zusammenstecken zweier Spitzer nicht behindernde, klemmend auf jeweils einen Spitzer aufsetzbare Spanfangkästen vorgesehen sein, wobei die Ausbildung bevorzugt so getroffen ist, daß die Längswände des Spanfangkastens auf der Oberseite des Spitzers aufliegen und die mit verlängerten Stirnwänden versehenen Spanfangkästen die Spitzerkanalein- und -austrittsstirnwände teilweise klemmend verrastend übergreifen.In order to utilize the combinability according to the invention into units comprising multiple sharpener, also for sharpener with chip collection boxes, in a further development of the invention, narrowed, not obstructing the plugging together of two sharpener, clamping chipboxes, which can be placed onto one sharpener in each case, can be provided, the design preferably being such that the Longitudinal walls of the chip catcher box rest on the top of the sharpener and the chip catcher boxes with elongated end walls partially overlap the snap channel entry and exit end walls in a locking manner.

Der in den Figuren 1 und 2 dargestellte Spitzer umfaßt ein übliches quaderförmiges Spitzergehäuse 1 mit einem Spitzerkanal 2, dessen Eintrittsöffnungen der einen Gehäusestirnwand 3 und dessen Austrittsöffnung in der gegenüberliegenden Stirnwand 4 angeordnet ist und dessen konische Flanke tangential zur Schneide eines Spitzermessers 5 angeordnet ist.The sharpener shown in FIGS. 1 and 2 comprises a conventional cuboid sharpener housing 1 with a sharpener channel 2, the inlet openings of one housing end wall 3 and the outlet opening of which is arranged in the opposite end wall 4 and the conical flank of which is arranged tangentially to the cutting edge of a sharpener knife 5.

Erfindungsgemnäß sind die Längsseitenwände 6 bzw. 7 mit komplementären Querrippen 8 und Zwischennuten 9 bzw. Querrippen 8' und Zwischennuten 9' versehen, so daß zwei Spitzer - wie man in Fig. 2 erkennen kann - seitlich klemmend aneinandergesteckt werden können und somit eine Baueinheit bilden. Selbstverständlich kann dabei eine beliebige Baueinheit auch aus drei und mehr Spitzern gebildet werden, wobei es sich bevorzugt dabei um Spitzer handeln soll, die jeweils zusammen gehören, beispielsweise zum Spitzen von Bleistiften unterschiedlicher Durchmesser oder auch von unterschiedlichen Kosmetikstiften bzw. unterschiedlich farbigen Kosmetikstiften.According to the invention, the longitudinal side walls 6 and 7 are provided with complementary transverse ribs 8 and intermediate grooves 9 or transverse ribs 8 'and intermediate grooves 9', so that two sharpener - as can be seen in Fig. 2 - can be laterally clamped together and thus form a structural unit . Of course, any unit can also be formed from three or more sharpeners, which should preferably be sharpeners that each belong together, for example for sharpening pencils of different diameters or also of different cosmetic pencils or differently colored cosmetic pencils.

Zur stärkeren Verbindung und zur Verhinderung eines einfachen Auseinanderziehens können die Rippen 8'' einen sich nach außen verbreiternden trapezförmigen Querschnitt aufweisen.For a stronger connection and to prevent simple pulling apart, the ribs 8 ″ can have a trapezoidal cross section that widens outwards.

Anstelle der in den Figuren 1 bis 3 gewählten Querrippen können auch in Längsrichtung des Spitzerkanals 2 verlaufende Längsrippen 8''' vorgesehen sein, wie sie in Fig. 4 gezeigt sind. Anstelle der Rippenausbildung können auch Noppen 8'''' zum Eingreifen in entsprechende Hülsen 9''' vorgesehen sein (vergl. hierzu Fig. 5).Instead of the transverse ribs selected in FIGS. 1 to 3, longitudinal ribs 8 ″ ″ extending in the longitudinal direction of the pointed channel 2 can also be provided, as shown in FIG. 4. Instead of the rib formation, knobs 8 '' '' can also be provided for engaging in corresponding sleeves 9 '' '(cf. FIG. 5).

Zur Ergänzung eines erfindungsgemäßen Spitzers zu einem Spitzer mit Spanfanggehäuse ist beim Ausführungsbeispiel nach den Figuren 6 und 7 ein Spanfangkasten 10 vorgesehen, der gegenüber dem Spitzergehäuse so verschmälert ist, daß seine Längsseitenwände 11 und 12 auf der Oberseite des Spitzers aufsitzen und dabei die Rippen voll seitlich herausstehen lassen, so daß der Spanfangkasten 10 das Zusammenstecken zweier Spitzer nicht behindert. Die Stirnwände 13 bzw. 14 des Spanfangkastens 10 sind nach unten verlängert und mit einer Rastwulst 15 versehen, welche in eine entsprechende Rastvertiefung 16 der Spitzerkanalein- und - austrittsstirnwände klemmend verrastend eingreifen.To supplement a sharpener according to the invention to a sharpener with a chip catch housing, a chip catch box 10 is provided in the exemplary embodiment according to FIGS. 6 and 7, which is narrowed relative to the sharpener housing in such a way that its longitudinal side walls 11 and 12 sit on the top of the sharpener and the ribs are fully to the side protrude so that the chip box 10 does not hinder the joining of two sharpener. The end walls 13 and 14 of the chip collection box 10 are extended downward and provided with a latching bead 15 which engages in a corresponding latching recess 16 of the pointed channel inlet and outlet end walls in a locking manner.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Neben einer Möglichkeit der Ausbildung der Verrastungsvorsprünge ähnelich der Ausbildung von handelsüblichen Klemmbausteinen könnte bei Vorsehen von Längs- oder Querrippen auch eine Konizität der Rippen und Nuten in Längsrichtung vorgesehen sein, um beim Zusammenstecken eine erhöhte Klemmarretierung auch in Zusammensteckrichtung erzielen zu können, die in Verbindung mit der trapezförmigen Ausbildung gemäß Fig. 3 ein Trennen mehrerer zusammengesteckter Spitzer in allen Richtungen sicher verhindert, so daß ein ungewolltes Trennen nicht stattfinden kann.The invention is not restricted to the exemplary embodiments shown. In addition to a possibility of the formation of the locking projections similar to the formation of commercially available clamping blocks, a taper of the ribs and grooves in the longitudinal direction could also be provided if longitudinal or transverse ribs were provided, in order to be able to achieve an increased clamping lock in the plugging direction when plugging together, which in connection with 3 a separation of several plug-in sharpener prevented in all directions, so that an unwanted separation can not take place.

Bei der Angabe, daß die erfindungsgemäße Ausgestaltung für im wesentlichen quaderförmige Spitzergehäuse gedacht ist, sind selbstverständlich auch schiefe Quader mitgemeint, also die üblichen Einschiebspitzer mit Keilform, bei denen die Deckfläche und die Bodenfläche gegeneinander geneigt sind, so daß sie unter Spannung in eine Schlaufe eines Schülermäppchens eingesteckt werden können. Diese Keilform hat ja nichts damit zu tun, daß die beiden Längsseitenwände zueinander parallel ausgebildet sein können.When specifying that the configuration according to the invention is intended for essentially cuboid pointed housings, inclined cuboids are of course also meant, i.e. the usual insertion sharpener with a wedge shape, in which the top surface and the bottom surface are inclined towards one another, so that they are tensioned into a loop Pupil case can be inserted. This wedge shape has nothing to do with the fact that the two longitudinal side walls can be formed parallel to each other.

Darüber hinaus ist die erfindungsgemäße Ausgestaltung von Spitzern auch sehr vorteilhaft für eine andere Art der Halterung in Schülermäppchen anstelle der bereits im vorherigen Absatz angesprochenen Halterungsschlaufen, die ja auch im wesentlichen keilförmige Spitzergehäuse erfordert. Durch Anbringen einer entsprechend mit Gegenvorsprüngen bzw. Vertiefungen versehenen Platte oder Schiene im Schülermäppchen können die Spitzer durch einfaches Aufstecken auf diese fest oder mit Hilfe von Schlaufen im Schülermäppchen gehalterte Platte oder Schiene aufgesteckt und so sehr einfach und sicher gehaltert werden. Die starre oder lösbare Halterung der Platte oder Schiene im Mäppchen durch Einkleben oder mit Hilfe von Schlaufen ist sehr viel einfacher zu realisieren als eine Halterung durch eine den Spitzer übergreifende Schlaufe, da diese ja sich mit der Zeit ausweitet und somit die Halterungsfunktion verlorengeht.In addition, the configuration of sharpener according to the invention is also very advantageous for a different type of holder in student pencil cases instead of the holder loops already mentioned in the previous paragraph, which also requires essentially wedge-shaped sharpener housings. By attaching one with counter protrusions or recesses provided plate or rail in the student's case, the sharpener can be attached by simply attaching it to the plate or rail which is held in the student's case by means of loops, and can thus be held very easily and securely. The rigid or detachable mounting of the plate or rail in the pencil case by gluing or with the help of loops is much easier to implement than a mounting using a loop overlapping the sharpener, since this expands over time and thus the mounting function is lost.

Schließlich eignet sich die erfindungsgemäße Profilierung der Spitzerseitenflächen auch sehr einfach dazu, um einen solchen Spitzer auch in anderen Behältern, insbesondere auch in Dosen, zu haltern, so daß man Dosenspitzer mit unterschiedlichen Spanfangdosen sehr einfach mit den zugehörigen Spitzern bestücken kann. Es bedarf dann lediglich einer Gegenfläche an der Innenseite der Dose, um den jeweils gewünschten Spitzer anzustecken, der dann mit seiner Spitzeröffnung natürlich genau unter der entsprechenden Einstecköffnung der Dose, beispielsweise des Dosendeckels, zu liegen kommen muß.Finally, the profiling of the pointed side surfaces according to the invention is also very simple to hold such a sharpener in other containers, in particular also in cans, so that can sharpener with different chip collecting boxes can be very easily equipped with the associated sharpener. All that is then required is a counter surface on the inside of the box in order to attach the desired sharpener, which of course must then come to rest with its pointed opening exactly under the corresponding insertion opening of the box, for example the box lid.
