Description

Die Erfindung betrifft ein Handschreibgerät mit eingebautem Stempel der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a hand-held pen with built-in stamp of the type specified in the preamble of claim 1.

Ein derartiges Schreibgerät ist zum Beispiel aus dem DE-GM 84 18 819 oder 86 04 475 bekannt.Such a writing instrument is known for example from DE-GM 84 18 819 or 86 04 475.

Bei diesen Schreibgeräten nimmt die Halterung bzw. Mechanik für den Stempel so viel Platz in Anspruch, daß nur vergleichsweise wenig Platz für die Schreibmine selbst übrig bleibt. Üblicherweise werden darum für diese Schreibgeräte nur relativ kleine Schreibminen, z.B. nach DIN 16554, verwendet. Das hat zur Folge, daß die Schreibminen lange ehe die Stempelfarbe des Stempels verbraucht ist, ausgeschrieben sind und ausgewechselt werden müssen.With these writing instruments, the holder or mechanism for the stamp takes up so much space that only comparatively little space remains for the writing lead itself. For this reason, only relatively small writing leads, for example according to DIN 16554, are usually used for these writing instruments. As a result, the refills are written out long before the stamp color of the stamp is used up, and must be replaced.

Aus EP-A 0 322 550 ist ein Schreibgerät in Form eines Kugelschreibers mit zwei Minen, die durch Drehen des Schaftes abwechselnd in die Schreibstellung gebracht werden können, bekannt. In einer Führungshülse mit zwei seitlichen Längsschlitzen bewegen sich hierbei zwei Gleitschieber auf abgesetzten Führungsschienen hin und her. An den beiden Gleitschiebern sind jeweils Röhrchen zur Aufnahme der Schreibmine angebracht. In seinem äußeren Randbereich weist der Gleitschieber eine Nase auf, die mit Hilfe von Federn gegen die Schaltkurve einer Schaltkurvenhülse gedrückt wird. Ein Schreibgerät mit diesem Vorschubmechanismus ist nicht für größere Minen, sogenannte Großraumminen, geeignet.From EP-A 0 322 550 a writing instrument in the form of a ballpoint pen with two refills, which can be brought into the writing position alternately by rotating the shaft, is known. In a guide sleeve with two lateral longitudinal slots, two sliding slides move back and forth on offset guide rails. Tubes for receiving the writing lead are attached to each of the two sliding slides. In the outer edge region, the slide valve has a nose which is pressed against the switching curve of a switching curve sleeve with the aid of springs. A writing instrument with this feed mechanism is not suitable for larger refills, so-called large refills.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Handschreibgerät dieser Art zu schaffen, in welches ohne Änderung der äußeren Abmessungen des Gehäuses größere Minen, insbesondere sogenannte Großraumminen, eingesetzt werden können.The present invention has for its object to provide a hand-held writing instrument of this type, in which larger leads, in particular so-called large refills, can be used without changing the external dimensions of the housing.

Zur Losung dieser Aufgabe werden die mit Anspruch 1 angegebenen Merkmale bei einem Handschreibgerät der gattungsgemäßen Art vorgeschlagen.To solve this problem, the features specified in claim 1 are proposed for a hand-held writing instrument of the generic type.

Der Grundgedanke der Erfindung besteht zum einen darin, für die Vorschubmechanik eine an sich z.B. nach der DE-OS 1 461 291 bekannte Drehmechanik zu verwenden, welche unter Zuhilfenahme der Kappe vom Stempelträger betätigt werden kann. Zum andern ist an den Stempelträger unmittelbar ein Teil der Mechanik angeformt, das so ausgebildet ist, daß die Mine in dieses unmittelbar eingesetzt werden kann, wodurch Platz in Axialrichtung des Schreibgeräts geschaffen ist. Dies ist gerade bei Handschreibgeräten notwendig, bei welchen der Stempelträger mit Stempel in Ruhelage sich in Axialrichtung der Schreibmine befindet.The basic idea of the invention is, on the one hand, for the feed mechanism to be e.g. to use known rotary mechanism according to DE-OS 1 461 291, which can be actuated by the stamp carrier with the aid of the cap. On the other hand, a part of the mechanism is formed directly on the stamp carrier, which is designed so that the lead can be inserted directly into it, thereby creating space in the axial direction of the writing instrument. This is especially necessary with hand-held writing instruments in which the stamp carrier with the stamp is in the rest position in the axial direction of the writing lead.

Für die Stempelausbildung eignen sich auch andere Konstruktionen, z.B. nach dem Schweizer Patent 656 354 oder dem deutschen Gebrauchsmuster 87 00 113.Other constructions are also suitable for stamp formation, e.g. according to the Swiss patent 656 354 or the German utility model 87 00 113.

Konstruktive Einzelheiten der Vorschubmechanik sind mit den weiteren Ansprüchen 2 bis 7 angegeben. Die Vorschläge nach den Ansprüchen 5 und 6 tragen insbesondere zu einer Montagefreundlichkeit der Vorschubmechanik bei.Structural details of the feed mechanism are specified in the further claims 2 to 7. The proposals according to claims 5 and 6 contribute in particular to the ease of installation of the feed mechanism.

Zur sicheren und vorteilhaften Betätigung der Vorschubmechanik wird die Kappenkonstruktion nach den Ansprüchen 8 bis 10 vorgeschlagen.For safe and advantageous actuation of the feed mechanism, the cap construction according to claims 8 to 10 is proposed.

Das erfindungsgemäße Schreibgerät mit Stempel weist ein Gehäuserohr 10 auf, in welchem axial verschiebbar eine Großraummine 11 angeordnet ist. Deren Spitze 11a kann aus einer Lagerposition gegen die Wirkung einer Schraubenfeder 12 durch die in der Schreibspitze 10a vorgesehene Bohrung 10c in eine Schreibposition ausgefahren werden.The writing instrument with stamp according to the invention has a housing tube 10 in which a large refill 11 is arranged so as to be axially displaceable. Its tip 11a can be extended from a storage position against the action of a helical spring 12 through the bore 10c provided in the writing tip 10a into a writing position.

Am hinteren Ende des Schreibgerätes ist ein Stempel 23 vorgesehen, der auf der Oberseite eines Stempelträgers 22 befestigt, vorzugsweise aufgeklebt, ist. Der Stempelträger 22 ist über ein im einzelnen nicht dargestelltes Schwenklager 28 an einem achsparallel verlaufenden Lagerschaft 21 eines in das rückwärtige Ende des Gehäuserohres 10 eingesetzten Stempelträgerkopfes 20 angelenkt. In Lagerposition befindet sich diese Stempelanordnung innerhalb der auf das rückwärtige Ende des Gehäuserohres 10 aufgesetzten Kappe 50, wie dies in den Figuren 3 bis 5 veranschaulicht ist. Zu Stempelzwecken ist das Schreibgerät gemäß Figur 1 aus der horizontalen in eine vertikale Lage mit nach oben gerichteter Spitze 10a zu bringen, in der der Stempelträger 22 mit Stempel 23 in eine horizontale Lage klappt.At the rear end of the writing instrument, a stamp 23 is provided, which is fastened, preferably glued, to the top of a stamp carrier 22. The stamp carrier 22 is articulated via a pivot bearing 28, not shown in detail, to an axially parallel bearing shaft 21 of a stamp carrier head 20 inserted into the rear end of the housing tube 10. In the storage position, this stamp arrangement is located within the cap 50 placed on the rear end of the housing tube 10, as is illustrated in FIGS. 3 to 5. For stamping purposes, the writing instrument according to FIG. 1 is to be brought from the horizontal into a vertical position with the tip 10a pointing upwards, in which the stamp carrier 22 with the stamp 23 folds into a horizontal position.

Dem Vorschub der Mine 11 dient eine Drehmechanik, deren Aufbau in der Explosionsdarstellung gemäß Figur 2 sowie in den vergrößerten Darstellungen gemäß Figur 7 bis 8 besser erkennbar ist.A rotary mechanism serves to advance the mine 11, the structure of which can be seen better in the exploded view according to FIG. 2 and in the enlarged views according to FIGS. 7 to 8.

In an sich bekannter Weise läßt sich mittels einer derartigen Mechanik die Schreibmine 11 durch Verdrehen des Stempelträgerkopfes 20 bzw. der auf diesen aufgesetzten Kappe 50 aus der Lagerposition in die Schreibposition vorschieben und aus dieser unter der Wirkung der Schraubenfeder 12 wieder zurückführen.In a manner known per se, by means of such a mechanism, the writing lead 11 can be advanced from the storage position into the writing position by rotating the stamp carrier head 20 or the cap 50 placed thereon and can be returned from the latter under the action of the helical spring 12.

Im einzelnen besteht die Vorschubmechanik aus einer am Trägerkopf 20 angeformten Trägerkopfhülse 24, die an ihrem freien, in das Gehäuserohr 10 ragenden Ende eine Vorschubkurve 25 trägt.In detail, the feed mechanism consists of a support head sleeve 24 integrally formed on the support head 20, which carries a feed curve 25 at its free end projecting into the housing tube 10.

In die Trägerkopfhülse 24 ist eine Vorschubhülse 30 verdrehbar eingesetzt, in deren Bohrung 33 die Großraummine 11 mit ihrem hinteren Ende eingesetzt ist. Auf der Außenseite,der Vorschubhülse 30 ist ein Führungsstück 31 mit ballig ausgebildeten Nocken 31a,b vorgesehen, welche gleitend und kraftschlüssig auf der Vorschubkurve 25 aufliegen. Die Vorschubhülse 30 ist innerhalb des Gehäuserohres 11 axial verschiebbar aber nicht verdrehbar gelagert. Um letzteres zu erreichen, wird die Vorschubhülse 30 mittels ihres Führungsstückes 31 geführt, das in die Führungsnut 41 einer in das hintere Ende des Gehäuserohres 10 unverdrehbar eingepreßten Führungsbuchse 40 eingreift. In diese Führungsbuchse 40 ist die Trägerkopfhülse 24 einzusetzen, die sich im montierten Zustand mit einem Kragenteil 26 an der Stirnkante 43 der Führungsbuchse 40 verdrehbar abstützt. Um den Trägerkopf 20 zu montieren, muß dieser gegenüber der Darstellung in Figur 2 in eine um 90° gedrehte Position gebracht werden, so daß das Kragenteil 26 beim weiteren Einschieben in das Gehäuserohr 10 mit der Führungsnut 41 in Eingriff gelangt. Um dies zu ermöglichen, muß die Länge a (vgl. Figur 8) des Kragenteils 26 etwas kleiner sein als die Breite b der Führungsnut 41. Im endmontierten Zustand soll die Trägerkopfhülse 24 mit möglichst wenig Spiel verdrehbar innerhalb der Führungsbuchse 40 gelagert sein. Um bei dieser Bedingung eine Montage zu ermöglichen, ist der Abstand c (vgl. Figur 2) zwischen dem Kragenteil 26 und der Rast 25c der Vorschubkurve 25 etwas größer als der Abstand d des Grundes der Führungsnut 41 von der spitzenfernen Stirnseite 10b des Gehäuserohres 10. Bei dieser Dimensionierung greift das Kragenteil 26 bei Einführen der Trägerkopfhülse 24 in die Führungsnut 41 ein, ehe die Rast 25c in den Bereich der Führungsbuchse 40 bzw. des Gehäusesrohres 10 gelangt, so daß ein weiterer Vorschub ohne Verklemmen möglich ist.In the carrier head sleeve 24, a feed sleeve 30 is rotatably inserted, in the bore 33 of the large refill 11 is inserted with its rear end. On the outside, the feed sleeve 30, a guide piece 31 with crowned cams 31a, b is provided, which rest on the feed curve 25 in a sliding and non-positive manner. The feed sleeve 30 is mounted axially displaceable but not rotatable within the housing tube 11. In order to achieve the latter, the feed sleeve 30 is guided by means of its guide piece 31 which engages in the guide groove 41 of a guide bush 40 which is pressed non-rotatably into the rear end of the housing tube 10. The carrier head sleeve 24 is to be inserted into this guide bushing 40, which in the assembled state is rotatably supported by a collar part 26 on the end edge 43 of the guide bushing 40. In order to mount the carrier head 20, it must be brought into a position rotated by 90 ° in relation to the illustration in FIG. 2, so that the collar part 26 engages with the guide groove 41 when it is pushed further into the housing tube 10. In order to make this possible, the length a (cf. FIG. 8) of the collar part 26 must be somewhat smaller than the width b of the guide groove 41. In the final assembled state, the carrier head sleeve 24 should be rotatably mounted within the guide bush 40 with as little play as possible. In order to enable assembly under this condition, the distance c (see FIG. 2) between the collar part 26 and the detent 25c of the feed curve 25 is somewhat larger than the distance d of the bottom of the guide groove 41 from the end 10b of the housing tube 10 remote from the tip. With this dimensioning, the collar part 26 engages when the carrier head sleeve 24 is inserted into the guide groove 41 before the catch 25c reaches the region of the guide bushing 40 or the housing tube 10, so that a further feed is possible without jamming.

Um die Gesamtmechanik gegen Herausfallen zu sichern, ist von vorn in das Gehäuserohr 10 ein Sprengring 13 eingesetzt, mit welchem verhindert wird, daß die Vorschubhülse 30 beim Auswechseln der Mine 11 herausfällt.In order to secure the overall mechanism against falling out, a snap ring 13 is inserted into the housing tube 10 from the front, with which it is prevented that the feed sleeve 30 falls out when the lead 11 is replaced.

Aufbau und Funktionsweise der Drehmechanik sind besser aus den vergrößerten Darstellungen gemäß Figur 7 bis 8 erkennbar.The structure and mode of operation of the rotary mechanism can be better seen from the enlarged representations according to FIGS. 7 to 8.

Wie Figur 8 zeigt, setzt sich die Vorschubkurve 25 aus zwei von einer mittleren Rast 25c ansteigenden Kurvenabschnitten 25a und 25b zusammen. An den spitzennahen Enden dieser Kurvenabschnitte befinden sich der Schreibposition entsprechende Rasten 25e und 25d. Auf dieser Vorschubkurve liegt das Führungsstück 31 mit den nebeneinander angeordneten, ballig ausgebildeten Nocken 31a und 31b auf. In der Lagerposition liegen die Nocken 31a und b nebeneinander an der Rast 25c an, während in Schreibposition wahlweise entweder der Nocken 31a in die Rast 25e oder der Nocken 31b in die Rast 25d eingreift.As FIG. 8 shows, the feed curve 25 is composed of two curve sections 25a and 25b rising from a central catch 25c. At the tip-near ends of these curve sections there are notches 25e and 25d corresponding to the writing position. The guide piece 31 with the crowned cams 31a and 31b arranged next to one another lies on this feed curve. In the storage position, the cams 31a and b lie next to one another on the catch 25c, while in the write position either the cam 31a engages in the catch 25e or the cam 31b in the catch 25d.

Diese Konstellation ist mit der Aufsicht gemäß Figur 7 veranschaulicht, während der Schnitt gemäß Figur 6 die Anordnung in Lagerposition zeigt.This constellation is illustrated with the supervision according to FIG. 7, while the section according to FIG. 6 shows the arrangement in the storage position.

Die Drehmechanik ist mittels des Trägerkopfes 20 betätigbar. Damit sich der Benutzer nicht am eingefärbten Stempel 23 beschmutzt, sollte die Kappe 50 über den Trägerkopf 20 mit Stempel 22, 23 geschoben sein. Um eine einwandfreie Drehmomentübertragung zu gewährleisten, muß eine drehschlüssige Verbindung zwischen Kappe 50 und Trägerkopf 20 hergestellt werden können. Zu diesem Zweck ist die Kappe 50 so gestaltet, daß sie nach Art eines Schlüssels nur in einer einzigen Position, nämlich der in den Figuren 3 bis 5 dargestellten, auf den Trägerkopf 20 aufgeschoben werden kann. Um dies zu gewährleisten, sind im Innern der Kappe 50 achsparallel im Abstand voneinander verlaufende Rippen 54 und 55 vorgesehen, die sich bei aufgeschobener Kappe beidseitig des Stempels 23 auf der Oberfläche des Stempelträgers 22 abstützen. Um ein sicheres und einfaches Einfädeln dieser Rippen 54 und 55 zu gewährleisten, ist der Abstand d der Rippen 54, 55 von der Stirnkante der Kappe 50 kleiner bemessen als der Abstand des Stempelträgerendes 22a von dem O-Ring 27. Ungebremst von diesem können die Rippen 54 und 55 zunächst eingefädelt werden und dann parallel zum Stempel 23 verlaufend beim Aufsetzen der Kappe 50 vorgeschoben werden.The rotary mechanism can be actuated by means of the carrier head 20. So that the user does not get dirty on the inked stamp 23, the cap 50 should be pushed over the carrier head 20 with stamps 22, 23. In order to ensure a perfect torque transmission, a rotational locking Connection between cap 50 and carrier head 20 can be made. For this purpose, the cap 50 is designed in such a way that it can be pushed onto the carrier head 20 in the manner of a key only in a single position, namely that shown in FIGS. 3 to 5. To ensure this, ribs 54 and 55 are provided in the interior of the cap 50, axially parallel and at a distance from one another, which are supported on the surface of the stamp carrier 22 on both sides of the stamp 23 when the cap is pushed on. In order to ensure a safe and simple threading of these ribs 54 and 55, the distance d of the ribs 54, 55 from the end edge of the cap 50 is smaller than the distance of the stamp carrier end 22a from the O-ring 27. The ribs can be braked by it 54 and 55 are first threaded in and then advanced parallel to the punch 23 when the cap 50 is put on.

Damit die aufgeschobene Kappe in axialer Richtung festgelegt ist, ist in eine Ringnut 29 (vgl. Figur 6) des Stempelträgerkopfes 20 ein aus Gummi bestehender O-Ring 27 eingelegt, der sich von innen an die aufgeschobene Kappe 50 reibschlüssig anlegt. Bei der Darstellung gemäß Figur 3 ist die Kappe 50 noch nicht in ihre das Verdrehen des Trägerkopfes 20 ermöglichende Position vorgeschoben.So that the pushed-on cap is fixed in the axial direction, an O-ring 27 made of rubber is inserted into an annular groove 29 (cf. FIG. 6) of the stamp carrier head 20, which O-ring 27 frictionally engages from the inside. In the illustration according to FIG. 3, the cap 50 has not yet been advanced into its position which enables the carrier head 20 to be rotated.

Mit der beschriebenen Kappenkonstruktion wird ferner erreicht, daß der Innenraum der Kappe 50 in keiner Position, also weder beim Aufstecken noch beim Verdrehen der Kappe mit dem eingefärbten Stempel 23 in Berührung kommt.With the described cap construction it is also achieved that the interior of the cap 50 does not come into contact with the inked stamp 23 in any position, that is to say neither when the cap is being fitted nor when the cap is being rotated.

Zweckmäßigerweise sind diese Rippen 54 und 55 Teil eines als Clipstütze dienenden Einsatzes 52, in dessen Nut 53 das der Clipbefestigung dienende Ende 57 des außen gelegenen Clips 56 eingreift. In dieser Position ist der Clip durch den eingeschobenen Kappenverschluß festgelegt, an dessen innerem Ende diese sogenannte Clipstütze 52 angeformt ist.These ribs 54 and 55 are expediently part of an insert 52 serving as a clip support, in the groove 53 of which the end 57 of the outside clip serving for the clip attachment 56 engages. In this position, the clip is fixed by the inserted cap closure, on the inner end of which this so-called clip support 52 is formed.

Claims (10)

  1. Hand-operated writing tool having a built-in stamp (23) fitted to a carrier (22) which is attached, pivotably about an axis perpendicular to the longitudinal axis of the writing tool between a position roughly parallel to the longitudinal axis and a position roughly perpendicular to the longitudinal axis, to a carrier head (20) inserted in a housing tube (10), a cap (50) being able to be slid in frictional engagement onto the carrier (22) in its position parallel to the longitudinal axis and the carrier head (20) exhibiting on the side opposite the carrier (22) a carrier head sleeve (24), in which there is inserted a feed sleeve (30) for a writing lead (11), which writing lead is displaceable, by actuation of the cap (50) mounted on the carrier head (20), out of the tip-side end of the housing tube (10) from a mounting position into a writing position, that end of the carrier head sleeve (24) jutting into the housing tube (10) exhibiting a feed curve (25) which possesses a catch which is close to the carrier head (20) and a catch which is remote from the carrier head (20) (25c, 25d, 25e), the feed sleeve (30) possessing lateral cams (31a, b), which bear in non-positive and sliding contact, under the action of a spring (12), upon the feed curve (25), and the carrier head (20) with the carrier head sleeve (24) being mounted in a twistable but non-displaceable manner on the housing tube (10) and the feed sleeve (30) being mounted in an axially displaceable but non-twistable manner within the housing tube (10), the feed sleeve (30) further exhibiting just one bore (33), which receives the end of the lead (11) and extends over the entire length of the feed sleeve (30) up to the end wall of the feed sleeve, and the cams (31a, 31b) being fitted to the feed sleeve (30) in such a way that, in the mounting position of the full-size lead (11), the end wall of the feed sleeve, and hence that end of the full-size lead (11) which bears against it, reaches right up to the carrier head (20).
  2. Hand-operated writing tool according to Claim 1, characterized in that in the housing tube (10) there is inserted a guide bush (40) which is fixedly connected thereto and has an axial guide groove (41), in which there is mounted, in an axially displaceable manner, the feed sleeve (30), which engages by means of a guide piece (31) in the guide groove (41), the guide piece (31) exhibiting, at its end facing the feed curve (25), the cam (31a, b) which bears upon the said feed curve.
  3. Hand-operated writing tool according to Claim 1 or 2, characterized in that the feed curve (25) exhibits two curve segments (25a, b), which ascend in the axial direction and exhibit, at their ends remote from the writing tip (10a), a catch corresponding to the mounting position of the writing lead (11) and, at their end close to the writing tip (10a), catches (25d, 25e) corresponding to the writing position.
  4. Hand-operated writing tool according to Claim 3, characterized in that on the guide piece (31) there are provided two mutually adjacent, spherically configured cams (31a, b), which respectively engage alternately in one of the two catches (25d, e) assigned to the writing position.
  5. Hand-operated writing tool according to one of Claims 2 to 4, characterized in that the feed sleeve (30), in a region outside the feed curve (25) and facing the writing tip (10a), preferably between the two curve segments (25a, b), exhibits an annular collar (32), which projects radially over the periphery of the feed sleeve (30) and bears in a sliding manner upon the tip-side end face (43) of the guide bush (40).
  6. Hand-operated writing tool according to Claims 3 and 5, characterized in that the length (a), measured in the peripheral direction, of the collar part (26) corresponds to the width (b) of the guide groove (41), and the axial distance (c) of the collar (26) from the catch (25c) remote from the writing tip is greater than the axial distance (d) of the guide groove (41) from that front edge (42) of the guide bush (40) which is remote from the tip.
  7. Hand-operated writing tool according to one of Claims 1 to 6, characterized in that the bore (33) in the feed sleeve (30), which-bore receives the end of the lead (11), corresponds in its cross-section to the cross-section of that end of a full-size lead (11) which is remote from the tip.
  8. Hand-operated writing tool according to one of Claims 1 to 7, characterized in that the carrier head (20) exhibits, on its outer periphery, a ring consisting of elastomeric material, preferably an O-ring (27) placed in a groove (29) and consisting of rubber, over which the cap (50) can be slid in frictional engagement.
  9. Hand-operated writing tool according to one of Claims 1 to 8, characterized in that within the cap (50) there are provided two stop ribs (54, 55), which extend in the axial direction and, when the cap (50) is slid on, bear upon the top side of the stamp carrier (22) on both sides of the stamp (23) steeped in stamping ink.
  10. Hand-operated writing tool according to Claims 8 and 9, characterized in that the axial distance (d) between the tip-side end (58) of the ribs (54, 55) is less than the axial distance (e) of the tip-remote end (22a) of the stamp carrier (22) from the elastomeric ring (27).
