Description

Die Erfindung betrifft einen Holzstift zum Malen, Schreiben, Zeichnen oder für kosmetische mit den Merkmalen des Oberbegriffs des Anspruchs 1. Ein solcher Stift ist aus zwei Schafthälften gebildet, in denen jeweils eine sich in Stiftlängsrichtung erstreckende Nut vorhanden ist. Die Nuten bilden zusammen einen zentralen, eine Mine aufnehmenden Hohlraum. Die Nut einer Schafthälfte ist von zwei Verbindungsflächen flankiert, welche mit den Verbindungsflächen der jeweils anderen Schafthälfte verklebt sind. Bei herkömmlichen Holzstiften verlaufen die Verbindungsflächen einer jeden Schalenhälfte in einer gemeinsamen Planebene, die - zumindest annähernd -die Mittellängsachse des Stifts schneidet. Die Schafthälften weisen dabei eine einem Halbkreis entsprechende Querschnittsform auf.The invention relates to a wooden pencil for painting, writing, drawing or for cosmetic with the features of the preamble of claim 1. Such a pin is formed of two half-legs, in each of which a groove extending in the longitudinal direction of the groove is present. The grooves together form a central, a mine receiving cavity. The groove of a shaft half is flanked by two connecting surfaces, which are glued to the connecting surfaces of the other shaft half. In conventional wood pencils, the connecting surfaces of each shell half extend in a common plane plane which, at least approximately, intersects the central longitudinal axis of the pencil. The shaft halves have a cross-sectional shape corresponding to a semicircle.

Die DE 1 953 985 offenbart ein Verfahren zur Herstellung eines Stiftes, bei dem Brettchen, die Nuten zur Aufnahme von Minen aufweisen, miteinander verklebt werden.The DE 1 953 985 discloses a method of manufacturing a pin in which boards having grooves for receiving leads are glued together.

Bei der Herstellung von Holzstiften tritt das Problem auf, dass stets ein gewisser Anteil der Stifte aufgrund einer Verbiegung als Ausschuss aussortiert werden muss. Die Verbiegung, die hauptsächlich in einer sich quer zu der Trennfuge zwischen den Schafthälften erstreckenden Richtung erfolgt, beruht in erster Linie auf einen unterschiedlichen Feuchtigkeitsgehalt der Schafthälften. Die Folge ist, dass sich die Schafthälfte mit dem höheren Feuchtigkeitsgehalt bei der Trocknung stärker verkürzt als die andere Schafthälfte. Daneben kann auch eine unterschiedliche Holzbeschaffenheit, z.B. Dichteschwankungen, der beiden Schaftflächen die Ursache für eine Verbiegung der Stifte sein.In the production of wood pencils, the problem arises that always a certain proportion of the pins due to a bending must be sorted out as broke. The bending, which occurs mainly in a direction transverse to the parting line between the leg halves extending direction, based primarily on a different moisture content of the sheep halves. The result is that the half of the stock with the higher moisture content during drying dries faster than the other half of the stock. In addition, a different wood texture, such as density fluctuations, the two shank surfaces be the cause of a bending of the pins.

Davon ausgehend besteht die Aufgabe der Erfindung darin, einen Stift vorzuschlagen, der sich mit geringerem Ausschuss herstellen lässt als herkömmliche Holzstifte.Based on this, the object of the invention is to propose a pen that can be produced with less waste than conventional wooden pencils.

Diese Aufgabe wird nach Anspruch 1 dadurch gelöst, dass die Verbindungsflächen einer jeden Schafthälfte nicht vollständig in einer gemeinsamen Planebene verlaufen. Es hat sich überraschenderweise herausgestellt, dass ein Stift mit einer solchen Ausgestaltung eine verringerte Neigung aufweist, sich insbesondere aufgrund unterschiedlicher Feuchtigkeitsgehalte der Schafthälften zu verbiegen. Für die Ausgestaltung der Schafthälften bzw. der sich daran befindlichen Verbindungsflächen gibt es ein große Vielfalt an Variationsmöglichkeiten. Wenn, wie dies bei einer bevorzugten Ausführungsvariante vorgesehen ist, die Schafthälften unterschiedlich eingefärbt sind, ergeben sich viele optische Gestaltungsmöglichkeiten für den Spitzkegel des Stiftes.This object is achieved according to claim 1, characterized in that the connecting surfaces of each shaft half do not extend completely in a common plane plane. It has surprisingly been found that a pin with such a configuration has a reduced tendency to bend, in particular due to different moisture content of the sheep halves. For the design of the sheep halves or the connecting surfaces located there, there is a large variety of possible variations. If, as is provided in a preferred embodiment, the sheep halves are colored differently, there are many optical design options for the pointed cone of the pen.

Bei einem bevorzugten Ausführungsbeispiel sind die Schafthälften als Gleichteile ausgebildet, was die Produktion von Stiften vereinfacht, da für einen bestimmten Stifttyp nur einheitlich gestaltete Schafthälften hergestellt werden müssen.In a preferred embodiment, the leg halves are formed as equal parts, which simplifies the production of pins, since for a given type of pin only uniformly shaped leg halves have to be produced.

Die Erfindung wird nun unter Bezugnahme auf die in den beigefügten Zeichnungen dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

In Fig. 1 ist ein Holzstift, im Folgenden wird vereinfachend von einem Stift 1 gesprochen, gezeigt, dessen Schaft 2 in üblicher Weise aus zwei in Stiftlängsrichtung bzw. in Richtung der Mittellängsachse 3 des Stifts 1 getrennten Schafthälften 4a,b gebildet ist. Die Schafthälften bestehen z.B. aus Jelutong-, Gmelina- oder Zedernholz. Der Stift 1 weist spätestens nach dem ersten Spitzen mit Hilfe eines Stiftspitzers einen Spitzkegel 5 auf. In jeder Schafthälfte 4a,b ist eine sich in Stiftlängsrichtung 3 erstreckende Nut 6 eingebracht. Die Nuten 6 bilden im fertigen Stift 1 einen zentralen, eine Mine 7 aufnehmenden Hohlraum 8. Die Nut 6 ist jeweils von zwei sich in Stiftlängsrichtung erstreckenden, in der Draufsicht gemäß Fig. 2 im Wesentlichen rechteckigen Verbindungsflächen 9, 10 gebildet, welche im fertigen Stift 1 durch eine Klebung miteinander verbunden sind.In Fig. 1 is a wooden pin, in the following is spoken simplistic of a pin 1, shown, the shaft 2 is formed in a conventional manner from two separate in the longitudinal direction of the pin or in the direction of the central longitudinal axis 3 of the pin 1 sheep halves 4a, b. The sheep halves consist for example of jelutong, gmelina or cedar wood. The pin 1 has a pointed cone 5 at the latest after the first tip with the aid of a pen tip. In each leg half 4a, b is a in the pin longitudinal direction 3 extending groove 6 is introduced. The grooves 6 form in the finished pin 1 a central, a mine 7 receiving cavity 8. The groove 6 is in each case of two extending in the pin longitudinal direction, in plan view Fig. 2 formed substantially rectangular connecting surfaces 9, 10, which are connected to each other in the finished pin 1 by gluing.

Bei herkömmlichen Stiften sind die Schafthälften, wie Fig. 3 zu entnehmen ist, so gestaltet, dass ihre Verbindungsflächen 9, 10 in einer gemeinsamen Planebene 12 verlaufen, wobei die Planebene 12 die Mittellängsachse 3 des Stiftes 1 schneidet. Die Schafthälften 4a,b sind hier somit derart ausgestaltet, dass sie durch eine rechtwinklig zur Planebene 12 verlaufende, die Mittellängsachse 3 schneidende Planebene 13 in zwei Teilschafthälften 14, 15 unterteilt werden, welche eine identische Form aufweisen. Die Ebene 13 bildet somit die Spiegelebene für die Teilschafthälften 14, 15.In conventional pens, the sheep halves, such as Fig. 3 can be seen, designed so that their connecting surfaces 9, 10 extend in a common plane plane 12, wherein the plane plane 12, the central longitudinal axis 3 of the pin 1 intersects. The shaft halves 4a, b are thus configured here in such a way that they are subdivided into two partial halves 14, 15, which have an identical shape, by means of a plane plane 13 which runs at right angles to the plane plane 12 and intersects the central longitudinal axis 3. The plane 13 thus forms the mirror plane for the part-shank halves 14, 15.

Bei einem erfindungsgemäßen Stift dagegen sind, wie Fig. 4 bis Fig. 6 zu entnehmen ist, die Schafthälften 4a,b anders gestaltet und zwar so, dass die Verbindungsflächen 9, 10 jeder der beiden Schafthälften 4a,b nicht vollständig in einer gemeinsamen Planebene verlaufen. Dies bedeutet, dass die Verbindungsflächen einer Schafthälfte allenfalls nur Teilflächen aufweisen, welche in einer gemeinsamen Planebene verlaufen. Die Schafthälften sind dabei in gewisser Weise miteinander verzahnt. Aufgrund dieser Ausgestaltung der miteinander verbundenen Schafthälften ist die Steifigkeit des Stiftes erhöht, so dass eine Verbiegung quer zu den Schafthälften, also etwa in Richtung des Pfeiles 16 in Fig. 1, erschwert ist. Durch Versuche konnte gezeigt werden, dass der bisherige Ausschuss in Folge Verbiegung von Holzstiften von bis 15% auf weniger als 5% gesenkt werden kann. Der Versteifungseffekt dürfte im Grunde darauf zurückzuführen sein, dass jeweils eine Teilschafthälfte 14, 15 in Verbiegungsrichtung entsprechend Pfeil 16 eine größere Dicke 17 aufweist, als die jeweils andere Teilschafthälfte 14, 15.In a pen according to the invention, however, are as Fig. 4 to Fig. 6 it can be seen, the sheep halves 4a, b designed differently and in such a way that the connecting surfaces 9, 10 of each of the two leg halves 4a, b do not extend completely in a common plane Plane. This means that the connecting surfaces of a shaft half at most only have partial surfaces which extend in a common plane plane. The sheep halves are interlinked in a certain way. Due to this configuration of the interconnected leg halves, the stiffness of the pin is increased, so that a bending transversely to the leg halves, ie approximately in the direction of the arrow 16 in Fig. 1 , is difficult. Experiments have shown that the previous scrap can be reduced to less than 5% as a result of wood pin bending up to 15%. The stiffening effect should basically be due to the fact that in each case one part of the shaft 14, 15 in the direction of bending according to arrow 16 has a greater thickness 17 than the respective other part of the shaft 14, 15.

Die Form der Verbindungsflächen 9, 10 kann sehr unterschiedlich gestaltet sein. Bei dem in Fig. 4 gezeigten Stift beispielsweise weisen die Verbindungsflächen 9, 10 einen ersten sich an den die Mine 7 aufnehmenden Hohlraum 8 anschließenden Flächenbereich 9', 10' auf, wobei diese Flächenbereiche auf einer gemeinsamen, die Mittellängsachse 3 des Stiftes 1 schneidenden Planebene 12 verlaufen, was einen fertigungstechnischen Vorteil mit sich bringt. An die Flächenabschnitte 9', 10' schließt sich jeweils ein Flächenabschnitt 9", 10" an, welcher außerhalb der Planebene angeordnet ist und etwa auf einer Kreissekante verläuft. Die Teilflächen 9', 9" und 10', 10" erstrecken sich über die gesamte Länge der Schafthälften 4a,b und weisen in der Draufsicht gemäß Fig. 2 eine rechteckige Umrissform auf. Die beiden Teilflächen 10, 10' verlaufen mit einem Abstand 18 und parallel zueinander.The shape of the connecting surfaces 9, 10 can be designed very differently. At the in Fig. 4 The pin shown, for example, the connecting surfaces 9, 10 a first to the mine 7 receiving cavity 8 subsequent surface area 9 ', 10', said surface areas on a common, the central longitudinal axis 3 of the pin 1 intersecting plane plane 12 extend, which brings a manufacturing advantage with it. To the surface portions 9 ', 10' is followed in each case a surface portion 9 ", 10", which is arranged outside the plane Plane and extends approximately on a circular edge. The partial surfaces 9 ', 9 "and 10', 10" extend over the entire length of the shaft halves 4a, b and point in the plan view according to Fig. 2 a rectangular outline shape. The two partial surfaces 10, 10 'extend at a distance 18 and parallel to one another.

Bei dem in Fig. 5 gezeigten Stift verlaufen die Verbindungsflächen 9, 10 einer Schafthälfte 4a,b vollständig in Planebenen 19. Es liegt hier eine ähnliche Ausgestaltung vor wie bei dem Stift von Fig. 4. Es fehlen lediglich die an den Hohlraum 8 angrenzenden Flächenbereiche, welche in einer gemeinsamen Planebene angeordnet sind. Die Planebenen 19 verlaufen dabei ebenfalls parallel zueinander und weisen einen Abstand 18 auf. Der in Fig. 5 gezeigte Stift weist keine runde, sondern eine eher dreieckige Umrissform auf. Denkbar sind natürlich auch andere z.B. sechseckige oder ovale Umrissformen.At the in Fig. 5 shown pin run the connecting surfaces 9, 10 of a shaft half 4a, b completely in Plankenen 19. It is here a similar configuration as in the pin of Fig. 4 , It only lacks the surface adjacent to the cavity 8 surface areas, which are arranged in a common plane plane. The Plinkenen 19 also run parallel to each other and have a distance 18. The in Fig. 5 shown pen has no round, but a rather triangular outline shape. Conceivable, of course, are other, for example, hexagonal or oval outline shapes.

Bei dem in Fig. 6 gezeigten Stift, der ebenfalls eine dreieckige Umrissform hat, weist eine Verbindungsfläche 9 einer Schafthälfte 4a,b eines sich in Richtung der Mittellängsachse 3 des Stiftes erstreckende Rippe 20 und die mit ihr zusammenwirkende Verbindungsfläche 10 der jeweils anderen Schafthälfte 4a,b eine komplementär zur Rippe 20 ausgemuldete Rinne 22 auf. Es liegt hier eine besonders deutlich erkennbare Verzahnung der Schafthälften vor. An die die Oberfläche der Rippe 20 und den Grund der Rinne 22 bildenden Flächenbereiche schließt sich jeweils beidseitig ein Flächenbereich 9', 10' und 9", 10" an, wobei die erstgenannten Flächenbereiche sich von dem die Mine aufnehmenden Hohlraum 8 wegerstrecken und die letztgenannten Flächenbereiche bis zur Oberfläche 23 der Schafthälften 4a,b erstrecken.At the in Fig. 6 shown pin, which also has a triangular outline, has a connecting surface 9 of a shaft half 4a, b extending in the direction of the central longitudinal axis 3 of the pin rib 20 and the cooperating with their connecting surface 10 of the other shaft half 4a, b a complementary to the rib 20th gutted gutter 22 on. There is a particularly noticeable interlocking of the sheep halves here. At the surface of the rib 20 and the bottom of the groove 22 forming surface areas is followed on both sides by a surface area 9 ', 10' and 9 ", 10" with the first-mentioned surface areas extending away from the mine-receiving cavity 8 and extending the latter surface areas to the surface 23 of the sheep halves 4a, b.

Zur Herstellung eines erfindungsgemäßen Stiftes, exemplarisch wird auf den in Fig. 4 gezeigten Stift Bezug genommen, wird, wie bei der Herstellung herkömmlicher Holzstifte auch, von zwei Brettchen oder Tafeln 24a,b ausgegangen. In miteinander zu verbindende Flachseiten der Brettchen werden Nuten 6 eingefräst, welche sich parallel zueinander erstrecken und einen Abstand zueinander aufweisen. Die Nuten sind jeweils gleich gestaltet und bilden jeweils ein 180°-Segment des die Mine 7 aufnehmenden Hohlraumes 8. In den zwischen den Nuten 6 vorhandenen Flächenbereichen 25 werden die Verbindungsflächen 9, 10 geformt, beispielsweise gefräst. In die Nuten 6 der unteren Tafel 24b werden Minen 7 eingelegt und anschließend die beiden Tafeln 24a,b durch eine Verklebung an Flächenbereichen 25 bzw. den Verbindungsflächen 9, 10 miteinander verbunden. Anschließend werden aus den miteinander verbundenen Tafeln 24a,b Stiftrohlinge (nicht gezeigt) durch Schnitte längs der exemplarisch in Fig. 8 gezeigten Linien 26 heraus gesägt. Schließlich wird noch die Oberfläche der zunächst im Querschnitt noch rechteckigen Stiftrohlinge bearbeitet um beispielsweise runde oder dreieckige Stifte zu erzeugen. Als letzter Schritt werden die Stifte lackiert oder auf sonstige Weise mit einem in der Regel gefärbten Überzug versehen. Wenn die Schafthälften 4a,b bzw. die Tafeln 24a,b unterschiedliche Färbungen aufweisen, stoßen im Bereich des Spitzkegels 5 die unterschiedlich gefärbten Schafthälften 4a,b aneinander. Bei herkömmlichen Stiften (Fig. 3) verläuft die Trennlinie 27 zwischen den unterschiedlich gefärbten Schafthälften auf einer die Mittellängsachse 3 des Stifts 1 schneidenden Planebene 12 und dementsprechend im Bereich des Spitzkegels 5 - in der Seitenansicht von Fig. 1 gesehen - in Richtung der Mittellängsachse 3. Im Gegensatz dazu stoßen bei den erfindungsgemäßen Stiften 1 die unterschiedlich gefärbten Schafthälften 4a,b im Bereich des Spitzkegels 5 auf andere Weise aneinander, so dass sich je nach der Formgestaltung der Verbindungsflächen 9, 10 unterschiedliche Farbmuster ergeben. Bei dem Ausführungsbeispiel von Fig. 5 z.B. ist die sich durch die Verbindung der Teilflächen 9' und 10' ergebende Trennlinie 28 in der Planebene 12 angeordnet, verläuft folglich in der Draufsicht nach Fig. 1 in Richtung der Mittellängsachse 3. An die Trennlinie 28 schließt sich dann eine von dieser Richtung abweichende schräg nach oben verlaufende Trennlinie 29 an.For the production of a pin according to the invention, the example of FIG Fig. 4 As shown in the case of the production of conventional wooden pencils, it is assumed that two boards or boards 24a, b are used. In flat sides of the boards to be joined together, grooves 6 are milled in, which extend parallel to one another and are at a distance from each other. The grooves are each designed the same and each form a 180 ° segment of the mine 7 receiving cavity 8. In the present between the grooves 6 surface regions 25, the connecting surfaces 9, 10 are formed, for example, milled. In the grooves 6 of the lower panel 24b mines 7 are inserted and then the two panels 24a, b connected by bonding to surface areas 25 and the connecting surfaces 9, 10 with each other. Subsequently, from the interconnected panels 24a, b pin blanks (not shown) by cuts along the example in Fig. 8 Sawed out lines 26 shown. Finally, the surface of the first in the cross section still rectangular pin blanks is processed to produce, for example, round or triangular pins. As a last step, the pins are painted or otherwise provided with a generally colored coating. If the sheep halves 4a, b or the plates 24a, b have different colorations, the differently colored sheep halves 4a, b abut one another in the region of the pointed cone 5. In conventional pens ( Fig. 3 ) runs the dividing line 27 between the differently colored sheep halves on one the central longitudinal axis 3 of the pin 1 intersecting plane Plane 12 and accordingly in the region of the pointed cone 5 - in the side view of Fig. 1 In contrast to this, in the case of the pins 1 according to the invention, the differently colored blade halves 4a, b abut one another in the region of the pointed cone 5, so that different color patterns result depending on the shaping of the connecting surfaces 9, 10. In the embodiment of Fig. 5 For example, the dividing line 28 resulting from the connection of the partial surfaces 9 'and 10' is arranged in the plane plane 12, thus running in plan view Fig. 1 in the direction of the central longitudinal axis 3. At the dividing line 28 then adjoins a deviating from this direction obliquely upward separating line 29 at.
