To achieve this, the implement is provided with a depressor (8), which is configured as an extension of the housing (2) and can be actuated to displace the writing cartridge (4) both into the first and into the second position and in the first position, the depressor (8) is drawn out of the rear end of the housing (2).

Description

Schreibgerät writing implement
Die Erfindung bezieht sich auf ein Schreibgerät gemäß den im Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a writing instrument according to the features specified in the preamble of claim 1.
Aus der US-A-2 627 843 ist ein derartiges Schreibgerät bekannt, dessen Gehäuse aus zwei teleskopartig ineinander schiebbaren Teilen besteht. Im Vorderteil ist eine Schreibmine angeordnet, welche mittels einer Steuereinheit derart axial verschiebbar ist, daß in einer ersten Position die Minenspitze zum Schreiben aus dem Vorderteil herausragt und in einer zweiten Position die Minenspitze in das Vorderteil zurückgeschoben ist. Die Steuereinheit enthält eine axial verschiebbare sowie teilweise drehbar angeordnete erste Hülse, in welche die Schreibmine eingeklemmt ist und aus welcher die Schreibmine bei Bedarf nach Entfernen einer Gehäusespitze herausnehmbar ist. In eine kurze Spiralnut in der Außenfläche der drehbaren Steuerhülse greift ein Stift des Vorderteils ein, so daß die erste Hülse beim Drehen axial verschoben und somit die Schreibmine in die erste oder zweite Position verschoben wird. Das Gehäusehinterteil enthält innen eine weitere Hülse mit einem axialen Schlitz, in welchen ein am hinteren Ende des Vorderteils vorgesehener Vorsprung eingreift. Ferner enthält die weitere Hülse des Hinterteils einen axial nach innen gerichteten weiteren Vorsprung, der in eine lange zweite Spiralnut der Steuerhülse des Vorderteils eingreift. Beim Zusammenschieben des Vorderteils und des Hinterteils wird mittels des in die lange Spiralnut der ersten Hülse eingreifenden Vorsprunges der drehfest im Hinterteil angeordneten weiteren Hülse die erste Hülse entsprechend gedreht, wobei im Zusammenwirken mit der vorderen kurzen Spiralnut die erste Hülse axial nach hinten geschoben und somit die Minenspitze in das Gehäuse in die zweite Position zurückgezogen wird. In dieser zweiten Position sind die beiden Gehäuseteile teleskopartig ineinander geschoben und das Gehäuse weist insgesamt eine kurze Gesamtlänge auf. Um die Schreibmine bzw. die Schreibspitze in die erste Position bzw. die Schreibposition zu bringen, werden das Gehäusevorderteil und das Gehäusehinterteil axial auseinandergezogen, wobei die vorstehend erläuterten Funktionen in entgegengesetzten Richtungen ablaufen und die erste Hülse samt Schreibmine axial nach vorne verschoben und die Minenspitze aus dem Gehäuse in die erste Position oder Schreibposition geschoben wird. Nach dem vollständigen Auseinanderziehen der beiden Gehäuseteile weist das Schreibgerät seine maximale Länge auf. Die Handhabung des Schreibgerätes ist insoweit schwierig, als zum Einstellen der Schreibposition die beiden Gehäuseteile mit beiden Händen auseinander zu ziehen sind und zum Einstellen der zweiten Position mit einer gegenläufigen Bewegung die beiden Gehäuseteile ineinander zu schieben sind. Ferner ist eine gegenseitige Arretierung der beiden Gehäuseteile weder in der Schreibposition noch in der zweiten Position vorhanden. Durch unbeabsichtigte Relativbewegungen der beiden Gehäuseteile kann somit einerseits das ordnungsgemäße Schreiben beeinträchtigt werden oder zum anderen die Minenspitze aus der zweiten Position herausbewegt werden, wodurch die Gefahr des Beschmutzens von Kleidungsstücken oder dergleichen durch das Schreibmittel gegeben ist.Such a writing instrument is known from US-A-2 627 843, the housing of which consists of two telescopically slidable parts. A writing lead is arranged in the front part, which can be axially displaced by means of a control unit in such a way that in a first position the lead tip protrudes from the front part for writing and in a second position the lead tip is pushed back into the front part. The control unit contains an axially displaceable and partially rotatable first sleeve, into which the writing lead is clamped and from which the writing lead can be removed if necessary after removing a housing tip. A pin of the front part engages in a short spiral groove in the outer surface of the rotatable control sleeve, so that the first sleeve is axially displaced during rotation and thus the writing lead is displaced into the first or second position. The inside of the rear housing part contains a further sleeve with an axial slot, in which a projection provided at the rear end of the front part engages. Furthermore, the further sleeve of the rear part contains an axially inward directed projection which engages in a long second spiral groove of the control sleeve of the front part. When pushing the front part and the rear part together, the long Spiral groove of the first sleeve engaging projection of the further sleeve rotatably arranged in the rear part, the first sleeve is rotated accordingly, the first sleeve being pushed axially backwards in cooperation with the front short spiral groove and the mine tip being thus retracted into the housing in the second position. In this second position, the two housing parts are telescopically pushed into one another and the housing has a short overall length. In order to bring the writing lead or the writing tip into the first position or the writing position, the housing front part and the rear housing part are pulled apart axially, the functions explained above running in opposite directions and the first sleeve together with the writing lead being moved axially forward and the lead tip out the housing is pushed into the first position or writing position. After the two housing parts have been completely pulled apart, the writing instrument has its maximum length. The handling of the writing instrument is difficult insofar as the two housing parts have to be pulled apart with both hands to set the writing position and the two housing parts have to be pushed into one another with an opposite movement to set the second position. Furthermore, there is no mutual locking of the two housing parts either in the writing position or in the second position. Unintentional relative movements of the two housing parts can thus impair proper writing on the one hand or on the other hand move the tip of the lead out of the second position, which means that there is a risk of clothing or the like being soiled by the writing medium.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, das Schreibgerät mit geringem konstruktiven Aufwand dahingehend weiterzubilden, daß die Handhabung verbessert wird. Mit einem einmaligen Handgriff soll die Schreibmine in Funktion bzw. in die Schreibstellung gebracht werden und das Schreibgerät selbst verlängert werden. Das Schreibgerät soll in gewohnter Art mit einer Hand zu betätigen sein und insbesondere auf die zum Schreiben geeignete Größe mit der gleichen Bewegungsart verlängerbar sein wie zum Verkürzen und Einfahren der Schreibmine in die Ruheposition. Ferner soll eine zuverlässige Vorgabe der beiden Positionen der Schreibmine gewährleistet sein und unerwünschte Betätigungen sollen mit hoher Funktionssicherheit vermieden werden.Proceeding from this, the object of the invention is to further develop the writing instrument with little design effort so that handling is improved. The writing refill should be brought into function or in the writing position with a single movement and the writing instrument itself should be extended. The writing instrument should be able to be operated with one hand in the usual way and in particular be extendable to the size suitable for writing with the same type of movement as for shortening and retracting the writing lead into the rest position. Furthermore, a reliable specification of the two positions of the writing lead should be ensured and undesired actuations should be avoided with a high degree of functional reliability.
Die Lösung dieser Aufgabe erfolgt gemäß den im Patentanspruch 1 angegebenen Merkmalen. Das erfindungsgemäße Schreibgerät zeichnet sich durch eine funktionssichere Konstruktion und einfache Handhabung aus, wobei die Betätigung und Vorgabe der beiden Positionen ausschließlich durch Druckbewegung erfolgt. Das Schreibgerät enthält eine mittels eines Drückers betätigbare Steuereinheit, mittels welcher die Schreibmine wahlweise in die Schreibposition oder in die zurückgezogene Position bringbar ist, wobei synchron mit der jeweiligen Betätigung die Verlängerung des Schreibgerätes für die zum Schreiben geeignete Größe oder die Verkürzung des Schreibgerätes zum Verstauen oder Aufbewahren durchgeführt wird. Es ist somit ein kleines Schreibgerät geschaffen, welches zum Verstauen und Aufbewahren in kleinen Behältnissen, Taschen, insbesondere Hosentaschen, Notizblöcken, kleinen Taschenkalendern, kleinformatigen Terminplanern oder dergleichen geeignet ist. Die Steuereinheit enthält ein Kurventeil mit zwei bevorzugt hintereinander derart angeordneten Schaltkurven, daß mittels der ersten Schaltkurve die Schreibmine in die Schreibposition oder die zurückgezogene Position bringbar ist und die zweite Schaltkurve, den als Verlängerung ausgebildeten Drücker aus dem Gehäuse ausfährt oder in die kurze Position zurückfährt. Die erste Schaltkurve für die Schreibmine ist in bevorzugter Weise derart und insbesondere als eine Herzkurve ausgebildet, daß in den beiden möglichen Positionen eine funktionssichere Arretierung der Schreibmine gewährleistet ist. Die Schaltkurve für den Drücker ist vorzugsweise als eine Entriegelungs-Steuerkurve ausgebildet, wobei der Drücker, ausgehend von der verriegelten Position bei verkürztem Schreibgerät nach dem Entriegeln, insbesondere unter Einwirkung einer Federkraft in die verlängerte Position ausgefahren wird. In zweckmäßiger Weise ist das Kurventeil drehbar und axial verschiebbar im Gehäuse angeordnet und kann je nach Stellung das Herausfahren des Drückers verhindern oder diesen freigeben und entriegeln.This object is achieved according to the features specified in claim 1. The writing instrument according to the invention is characterized by a functionally reliable construction and simple handling, the actuation and specification of the two positions being carried out exclusively by pressure movement. The writing instrument contains a control unit which can be actuated by means of a pusher and by means of which the writing lead can be brought either into the writing position or into the retracted position, the extension of the writing instrument for the size suitable for writing or the shortening of the writing instrument for stowing or being synchronized with the respective actuation Storage is carried out. A small writing instrument is thus created which is suitable for stowing and storing in small containers, bags, in particular trouser pockets, notepads, small pocket calendars, small-format diaries or the like. The control unit contains a curve part with two switching curves, preferably arranged one behind the other, in such a way that the writing lead can be brought into the writing position or the retracted position by means of the first switching curve and the second switching curve, the pusher designed as an extension extends out of the housing or returns to the short position. The first switching curve for the writing lead is preferably designed in such a way and in particular as a heart curve that a functionally reliable locking of the writing lead is ensured in the two possible positions. The switching curve for the pusher is preferably designed as an unlocking control cam, the pusher being extended from the locked position in the shortened writing instrument after unlocking, in particular under the action of a spring force into the extended position. The cam part is expediently rotatably and axially displaceably arranged in the housing and, depending on the position, can prevent the lever from moving out or release and unlock it.

Fig. 1 zeigt einen axialen Schnitt durch das Schreibgerät mit einem Gehäuse 2, wobei eine Schreibmine 4 die erste Position bzw. Schreibposition einnimmt, in welcher eine Spitze 6 der Schreibmine 4 aus dem vorderen Ende des Gehäuses 2 zum Schreiben herausgeschoben ist. Am hinteren Ende des Gehäuses 2 ist ein Drücker 8 vorgesehen, welcher in dieser Position am hinteren Ende aus dem Gehäuse 2 herausgefahren ist und eine Verlängerung des Gehäuses bildet. Somit wird ein ordentliches Halten des Schreibgerätes beim Schreiben ermöglicht. In vorteilhafter Weise ist die Minenspitze 6 in einem Teleskopelement 10 geführt, welches in der dargestellten Schreibposition teilweise aus dem vorderen Ende des Gehäuses 2 herausragt. Mittels einer Feder 12, welche als Druckfeder ausgebildet ist und als Teleskopfeder bezeichnet wird, wird das Teleskopelement 10 und somit die Schreibmine 4 in Richtung der Längsachse 14 nach hinten gedrückt. Alternativ kann das Teleskopelement entfallen, wobei die Feder in bekannter Weise unmittelbar auf die Schreibmine einwirkt. Das Gehäuse 2 enthält ein insbesondere als eine im wesentlichen zylindrische Hülse, bevorzugt aus Metall, ausgebildetes Oberteil 16 und am vorderen Ende desselben eine Gewindehülse 18, wobei eine feste und bei Bedarf lösbare Verbindung, insbesondere mittels ineinandergreifender Gewinde 20, 21 vorgesehen ist. Die Gewindehülse 18 ist außen von einer am vorderen Ende mit einer Öffnung versehenen Kappe 22 umgeben.Fig. 1 shows an axial section through the writing instrument with a housing 2, a writing lead 4 assuming the first position or writing position in which a tip 6 of the writing lead 4 is pushed out of the front end of the housing 2 for writing. At the rear end of the housing 2, a pusher 8 is provided, which in this position has moved out of the housing 2 at the rear end and forms an extension of the housing. This enables the writing instrument to be held properly when writing. Advantageously, the lead tip 6 is guided in a telescopic element 10, which partially protrudes from the front end of the housing 2 in the illustrated writing position. By means of a spring 12, which is designed as a compression spring and is referred to as a telescopic spring, the telescopic element 10 and thus the writing lead 4 are pushed back in the direction of the longitudinal axis 14. Alternatively, the telescopic element can be omitted, the spring acting directly on the writing lead in a known manner. The housing 2 contains an upper part 16, in particular an essentially cylindrical sleeve, preferably made of metal, and a threaded sleeve 18 at the front end thereof, a fixed connection which can be released if required, in particular by means of interlocking threads 20, 21, being provided. The threaded sleeve 18 is surrounded on the outside by a cap 22 provided with an opening at the front end.
Im Inneren des Gehäuses 2 bzw. des Oberteils 16 ist eine Schalthülse 24 angeordnet. Die Schalthülse 24 ist ringförmig ausgebildet und im Gehäuse 2 festgelegt und insbesondere in axialer Richtung gesichert. Hierfür ist bevorzugt eine Rastverbindung vorgesehen, welche vorteilhaft einen radial nach innen gerichteten Vorsprung 26 des Oberteils 16 aufweist. Dieser Vorsprung 26 ist vorteilhaft ringförmig ausgebildet und greift in eine zugeordnete Ausnehmung 28 der Schalthülse 24, wobei diese Ausnehmung 28 zweckmäßig ebenfalls ringförmig ausgebildet ist. Alternativ kann diese Verbindung einen radial nach außen gerichteten Vorsprung der Schalthülse aufweisen, während das Gehäuse 2 bzw. das Oberteil 16 eine korrespondierende Ausnehmung aufweist. Ferner ist mit dem Gehäuse 2 ein Element 30 verbunden, welches über die Außenfläche des Oberteils 16 vorsteht und vorteilhaft als Rollschutz des Schreibgerätes dient. Die Schalthülse 24 enthält eine zum hinteren Ende gerichtete Verlängerung 32 mit Rastmitteln 34 zur Verbindung mit korrespondierenden Rastmitteln des erwähnten Elements 30, wobei die Rastmittel durch eine Öffnung des Gehäuse-Oberteils 16 nach innen durchgreifen. Mittels des Elements 30 ist somit auch eine Drehsicherung der Schalthülse 24 erreicht.A switching sleeve 24 is arranged inside the housing 2 or the upper part 16. The switching sleeve 24 is ring-shaped and fixed in the housing 2 and secured in particular in the axial direction. For this purpose, a latching connection is preferably provided, which advantageously has a radially inward projection 26 of the upper part 16. This projection 26 is advantageously annular and engages in an associated recess 28 of the switching sleeve 24, this recess 28 also advantageously being annular. Alternatively, this connection can have a radially outward projection of the switching sleeve, while the housing 2 or the upper part 16 has a corresponding recess. Furthermore, an element 30 is connected to the housing 2 and protrudes beyond the outer surface of the upper part 16 advantageously serves as roll protection of the writing instrument. The switching sleeve 24 contains an extension 32 directed towards the rear end with latching means 34 for connection to corresponding latching means of the element 30 mentioned, the latching means engaging inwards through an opening in the upper housing part 16. A rotation lock of the switching sleeve 24 is thus also achieved by means of the element 30.
Die im Gehäuse 2 axial und gegen Drehung gesicherte Schalthülse 24 ist ebenso wie ein Kurventeil 36 Bestandteil der bereits erwähnten Steuereinheit. Das Kurventeil 36 ist als eine Hülse ausgebildet und enthält einen vorderen Hohlraum 38 und einen hinteren Hohlraum 40, welche mittels einer Zwischenwand 42 getrennt sind. Im vorderen Hohlraum 38 ist - abgesehen von der Minenspitze 6 - die Schreibmine 4 angeordnet, während im hinteren Hohlraum 38 zumindest teilweise eine auf den Drücker 8 einwirkende Druckfeder 44 vorgesehen ist. Die Schreibmine 4 ist über ihr hinteres Ende bzw. einen dort angeordneten Abschlußstopfen an der Vorderseite der Zwischenwand 42 abgestützt. Das Kurventeil 36 weist auf seiner Außenfläche eine erste Schaltkurve 46 auf, welche insbesondere als eine Herzkurve ausgebildet ist. Die Schalthülse 24 wirkt über ein Kopplungselement 48 mit der Schaltkurve 46 zusammen. Bevorzugt greift als Kopplungselement 48 in die Schalt- oder Herzkurve 46 ein und ist ein mit der Schalthülse 24 verbundener und radial nach innen gerichteter Stift 48. Das Kurventeil 36 ist im Gehäuse 2 axial bewegbar und ferner drehbar angeordnet. Durch axiale Betätigung des Drückers 8, und zwar immer in der gleichen Druckrichtung gemäß Pfeil 50, wird mittels der Steuereinheit im Zusammenwirken der im Gehäuse 2 fixierten Schalthülse 24 und des bewegbaren Kurventeils 36 die Schreibmine 4 wahlweise in die erste Schreibposition oder in die zweite, zurückgezogene Ruheposition bewegt.The switching sleeve 24, which is axially secured against rotation in the housing 2, is part of the control unit already mentioned, as is a curved part 36. The curve part 36 is designed as a sleeve and contains a front cavity 38 and a rear cavity 40, which are separated by an intermediate wall 42. Apart from the lead tip 6, the writing lead 4 is arranged in the front cavity 38, while a compression spring 44 acting on the pusher 8 is at least partially provided in the rear cavity 38. The writing lead 4 is supported on its rear end or an end plug arranged there on the front of the intermediate wall 42. The curve part 36 has a first switching curve 46 on its outer surface, which is designed in particular as a heart curve. The switching sleeve 24 interacts with the switching curve 46 via a coupling element 48. Preferably, the coupling element 48 engages in the switching or heart curve 46 and is a pin 48 connected to the switching sleeve 24 and directed radially inward. The curve part 36 can be moved axially in the housing 2 and is also rotatable. By axially actuating the pusher 8, always in the same pressure direction according to arrow 50, the writing lead 4 is optionally withdrawn into the first writing position or into the second, by means of the control unit in cooperation with the switching sleeve 24 fixed in the housing 2 and the movable cam part 36 Rest position moved.
Alternativ kann im Rahmen der Erfindung, das Herausfahren des Drückers ohne Federkraft durch manuelles Herausziehen des Drückers aus dem hinteren Ende des Gehäuses erfolgen, wobei aber zuvor zum Herausschieben der Spitze der Schreibmine aus dem vorderen Ende des Gehäuses durch Druckbetätigung des Drückers erfolgte. Auch kann eine getriebliche Verbindung vorgesehen sein, welche nach dem Betätigen des Drückers zum einen die Minenspitze aus dem vorderen Ende und zum anderen den Drücker aus dem hinteren Ende des Gehäuses herausfährt. In bevorzugter Weise sind ferner Arretierungselemente vorgesehen, mittels welchen der Drücker in der herausgefahrenen Position bezüglich des Gehäuses gesichert ist. Das Kurventeil 36 besitzt bevorzugt axial hinter der ersten Schaltkurve 46 eine zweite Schaltkurve 52, über welche die Steuerung und Positionierung des Drückers 8 erfolgt. Der Drücker 8 enthält eine Führungshülse 54 und eine diese zumindest am hinteren Ende umgebende Druckknopfkappe 56, wobei die Führungshülse 54 und die Druckknopfkappe 56 insbesondere mittels Rastelementen fest und dauerhaft miteinander verbunden sind. Alternativ kann im Rahmen der Erfindung der Drücker 8 auch einteilig ausgebildet sein. Wie ersichtlich, ist innerhalb des Drückers 8 die Druckfeder 44 angeordnet, um den Drücker 8 in die dargestellte ausgefahrene Position zu fahren und dort zu halten. Der Drücker bzw. die Führungshülse 54 enthält ein radial nach innen gerichtetes Element 58, welchem ein weiteres, und zwar radial nach außen gerichtetes Anschlagelement 60 derart zugeordnet ist, daß der Drücker in der ausgefahrenen Position am hinteren Ende des Schreibgerätes fixiert ist. Das Anschlagelement 60 ist in besonders zweckmäßiger Weise als federnde Zunge am hinteren Ende des Kurventeils 36 ausgebildet. Alternativ können im Rahmen der Erfindung das Gehäuse 2 und der Drücker 8 miteinander korrespondierende Anschlagelemente aufweisen, um die axiale, nach hinten gerichtete Bewegung des Drückers 8 zu begrenzen.Alternatively, within the scope of the invention, the pusher can be pulled out without spring force by manually pulling the pusher out of the rear end of the housing, but prior to pushing the tip of the writing lead out of the front end of the housing by pressing the pusher. A geared connection can also be provided, which on the one hand moves the tip of the lead out of the front end and on the other hand the button out of the rear end of the housing after the trigger is actuated. In a preferred manner, locking elements are also provided, by means of which the handle is secured in the extended position with respect to the housing. The curve part 36 preferably has a second switching curve 52 axially behind the first switching curve 46, via which the control and positioning of the pusher 8 takes place. The pusher 8 contains a guide sleeve 54 and a push button cap 56 surrounding it at least at the rear end, the guide sleeve 54 and the push button cap 56 being firmly and permanently connected to one another, in particular by means of latching elements. Alternatively, in the context of the invention, the pusher 8 can also be formed in one piece. As can be seen, the compression spring 44 is arranged within the pusher 8 in order to move the pusher 8 into the illustrated extended position and to hold it there. The pusher or the guide sleeve 54 contains a radially inwardly directed element 58, to which a further, namely radially outwardly directed stop element 60 is assigned such that the pusher is fixed in the extended position at the rear end of the writing instrument. The stop element 60 is designed in a particularly expedient manner as a resilient tongue at the rear end of the curve part 36. Alternatively, within the scope of the invention, the housing 2 and the pusher 8 can have stop elements corresponding to one another in order to limit the axial, rearward movement of the pusher 8.
Ferner greift das vorzugsweise als ein radial nach innen gerichteter Vorsprung ausgebildete Element 58 in die zweite Schaltkurve 52 des Kurventeils 36 ein. Die zweite Schaltkurve 52 ist als eine T-Kurve ausgebildet und enthält an ihrem vorderen Ende wenigstens ein in Umfangsrichtung verlaufendes Nutteil 62. Wird der Drücker 8 in Richtung des Pfeiles 50 nach vorn in das Gehäuse 2 geschoben, so gelangt das Element 58 in das Nutteil 52, wodurch in Folge einer Drehung des Kurventeils 36 eine Arretierung des Drückers 8 in der eingeschobenen Position vorgegeben ist. Die oben erwähnte Verlängerung 32 der im Gehäuse 2 gegen Drehung gesicherten Schalthülse 24 korrespondiert mit einer in der Innenfläche des Drückers 8 angeordneten Axialnut derart, daß eine Drehsicherung des Drückers 8 gewährleistet ist.Furthermore, the element 58, which is preferably designed as a radially inward projection, engages in the second switching curve 52 of the curve part 36. The second switching curve 52 is designed as a T curve and contains at its front end at least one groove part 62 running in the circumferential direction. If the pusher 8 is pushed forward in the direction of arrow 50 into the housing 2, the element 58 reaches the groove part 52, as a result of a rotation of the cam part 36, a locking of the handle 8 in the inserted position is predetermined. The above-mentioned extension 32 of the switching sleeve 24 secured against rotation in the housing 2 corresponds to an axial groove arranged in the inner surface of the handle 8 in such a way that rotation of the handle 8 is ensured.
Fig. 2 zeigt eine Ansicht des Schreibgeräts in der Schreibposition, wobei zur Verlängerung der Drücker 8 aus dem Gehäuse 2 herausgefahren ist. Ferner ist die Spitze 6 und teilweise auch das Teleskopelement 10 aus dem vorderen Ende des Gehäuses 2 bzw. der dort angeordneten Kappe 22 des Gehäuses 2 herausgefahren. In dieser Schreibposition ist die Schreibmine mittels der vorstehend erläuterten Steuereinheit und insbesondere der als Herzkurve ausgebildeten ersten Schaltkurve und der zugeordneten Schalthülse gegen ein axiales Zurückschieben in das Gehäuse 2 fixiert. Fig. 3 zeigt in einem axialen Schnitt das Schreibgerät in der zweiten Position, wobei nunmehr der Drücker 8 nach den Ausführen einer Druckbewegung in Richtung des Pfeiles 50 größtenteils in das Gehäuse 2 eingeschoben ist. Durch die mit einer Hand durchführbare Druckbewegung auf den Drücker 8 wird im Zusammenwirken der Schalthülse 24, des Kupplungselements bzw. Stiftes 48 und der ersten Schaltkurve 46 das Kurventeil 36 um die Längsachse 14 derart gedreht, dass das radial nach innen gerichtete Element 58 des Drückers 8 bzw. der Führungshülse 54 in das oben erläuterte und in Umfangsrichtung verlaufende Nutteil der zweiten Schaltkurve 52 eingreift. Somit ist der Drücker 8, auf welchem die innenliegende Druckfeder 44 entgegen der Richtung des Pfeiles 50 einwirkt, gegen ein unerwünschtes Herausfahren gesichert. Da der Drücker 8 ferner bzgl. des Gehäuses 2 gegen Drehung gesichert ist, verbleibt der Drücker 8 funktionssicher in der dargestellten zweiten Position ebenso wie die in das Gehäuse 2 zurückgefahrene Spitze 6 der Schreibmine 4.Fig. 2 shows a view of the writing instrument in the writing position, wherein the pusher 8 is extended out of the housing 2 to extend. Furthermore, the tip 6 and partly also the telescopic element 10 are moved out of the front end of the housing 2 or the cap 22 of the housing 2 arranged there. In this writing position, the writing lead is fixed against axial sliding back into the housing 2 by means of the control unit explained above and in particular the first switching curve designed as a heart curve and the associated switching sleeve. Fig. 3 shows an axial section of the writing instrument in the second position, wherein the pusher 8 is now largely inserted into the housing 2 after a pressure movement in the direction of arrow 50. Due to the pressure movement on the pusher 8 which can be carried out with one hand, the cam part 36 is rotated about the longitudinal axis 14 in the interaction of the switching sleeve 24, the coupling element or pin 48 and the first switching curve 46 in such a way that the radially inwardly directed element 58 of the pusher 8 or the guide sleeve 54 engages in the above-described circumferential groove part of the second switching curve 52. Thus, the pusher 8, on which the internal compression spring 44 acts in the opposite direction of the arrow 50, is secured against undesired movement out. Since the pusher 8 is also secured against rotation with respect to the housing 2, the pusher 8 remains functionally reliable in the second position shown, as does the tip 6 of the writing lead 4 which is retracted into the housing 2.
Das Schreibgerät ist in Fig. 4 in der zusammengeschobenen, kurzen zweiten Position in einer seitlichen Ansicht dargestellt. Um das Schreibgerät wieder in die anhand von Fig. 1 und 2 erläuterte Schreibposition überzuführen, nimmt ein Benutzer das Gehäuse 2 derart in seine Hand, dass insbesondere mittels des Daumens auf den Drücker 8 eine Druckbewegung in Richtung des Pfeiles 50 ausgeführt werden kann. Infolge dieser Druckbewegung wird der Drücker 8 noch etwas tiefer in das hintere Ende des Gehäuses 2 eingeschoben, wobei mittels der Steuereinheit und insbesondere im Zusammenwirken der Schalthülse mit der ersten Schaltkurve das Kurventeil derart gedreht wird, dass die zweite Schaltkurve den Drücker 8 zu einer axialen Bewegung entgegen der Richtung des Pfeiles 50 freigibt und der Drücker 8 mittels der innenliegenden Druckfeder aus dem Gehäuse 2 herausgefahren wird bis er die in Fig. 1 und 2 dargestellte Position zum sicheren Führen des Schreibgerätes beim Schreiben einnimmt.The writing instrument is shown in Fig. 4 in the collapsed, short second position in a side view. To move the writing instrument back into the writing position explained with reference to FIGS. 1 and 2, a user takes the housing 2 in his hand in such a way that a pressure movement in the direction of arrow 50 can be carried out in particular by means of the thumb on the pusher 8. As a result of this pressure movement, the pusher 8 is pushed somewhat deeper into the rear end of the housing 2, the cam part being rotated by means of the control unit and in particular in cooperation with the switching sleeve with the first switching curve in such a way that the second switching curve pushes the pusher 8 into an axial movement releases against the direction of arrow 50 and the pusher 8 is moved out of the housing 2 by means of the internal compression spring until it assumes the position shown in FIGS. 1 and 2 for safely guiding the writing instrument when writing.
Fig. 5 bis 7 zeigt das Kurventeil 36 geschnitten bzw. in einer seitlichen Ansicht, wobei in Fig. 5 der Einfachheit halber die erste Schaltkurve 46 nicht dargestellt ist. Gemäß Fig. 6 ist die erste Schaltkurve als eine Herzkurve ausgebildet und enthält ein Kurventeil 66 zur Fixierung der Schreibmine in der herausgefahrenen Schreibposition. Die zweite Schaltkurve 52 ist bevorzugt als T-Kurve ausgebildet und weist am vorderen Ende das wenigstens eine in Umfangsrichtung laufende Nutteil 62 auf, um den Drücker in der zweiten in das Gehäuse eingeschobenen Position zu halten. Fig. 8 bis 10 zeigen die Schalthülse 24, wobei gemäß Fig. 9 das Rastmittel 34 an der Verlängerung 32 gut zu erkennen ist. Des weiteren enthält die Schalthülse 24 eine im wesentlichen radiale Öffnung oder Bohrung 68 zur Aufnahme des Kopplungselements oder Stiftes 48, welcher in die erste Schaltkurve des Kurventeils eingreift. 5 to 7 show the curve part 36 in section or in a side view, the first switching curve 46 not being shown in FIG. 5 for the sake of simplicity. According to FIG. 6, the first switching curve is designed as a heart curve and contains a curve part 66 for fixing the writing lead in the extended writing position. The second switching curve 52 is preferably designed as a T-curve and has at least one groove part 62 running in the circumferential direction at the front end in order to hold the handle in the second position pushed into the housing. 8 to 10 show the switching sleeve 24, the latching means 34 being clearly recognizable on the extension 32 according to FIG. 9. Furthermore, the switching sleeve 24 contains an essentially radial opening or bore 68 for receiving the coupling element or pin 48, which engages in the first switching curve of the curve part.
