Description

Die Erfindung bezieht sich auf einen Selbstfärbestempel mit Oberschlagfärbung, bestehend aus einem auf die zu stempelnde Fläche aufsetzbaren, ein der Aufsetzfläche gegenüberliegendes Farbkissen aufnehmenden Unterteil, aus einem im Unterteil angeordneten, zwischen dem Farbkissen und der Aufsetzfläche unter gleichzeitiger Wendung hinund herbewegbaren, die Druckplatte od. dgl. tragenden Stempeleinsatz sowie aus einem den Unterteil mit zwei an dessen Schmalseitenwänden geführten Seitenschenkeln umgreifenden, zur Aufsetzfläche hin gegen Federkraft verschiebbaren Betätigungsteil, in dessen Seitenschenkelenden die die Schmalseitenwände des Unterteils in geraden Langlöchern durchsetzende Wendeachse des Stempeleinsatzes gelagert ist, wobei im Unterteil an seinen Schmalseitenwänden feste Abwälzanschläge und am Stempeleinsatz mit Abstand von dessen Schwenkachse den Schmalseitenwänden zugekehrte, mittige Getriebeglieder angeordnet sind, die mit den Abwälzanschlägen bei der Hinund Herbewegung des Stempeleinsatzes nach Art von Zahnstangentrieben zusammenwirken.The invention relates to a self-inking stamp with overlap staining, consisting of a lower part which can be placed on the surface to be stamped and which receives an ink pad opposite the mounting surface, a lower part which is arranged in the lower part and which can be moved back and forth between the ink pad and the mounting surface with simultaneous turning, the printing plate or the like. Load-bearing stamp insert as well as from an actuating part encompassing the lower part with two side legs guided on its narrow side walls and displaceable towards the contact surface against spring force, in the side leg ends of which the turning side axis of the stamp insert penetrating the narrow side walls of the lower part is held in straight elongated holes, the lower part being on its narrow side walls fixed gear stops and on the punch insert at a distance from its pivot axis facing the narrow side walls, central gear members are arranged, which with the gear stops at the back and forth Interact movement of the stamp insert in the manner of rack and pinion drives.

Ein solcher Selbstfärbestempel ist bereits bekannt (US-PS 4 852 489). Dabei weisen die Getriebeglieder zwei symmetrische, aus einem geraden und einem schrägen Abschnitt bestehende Schlitze oder Kulissen auf. Als Abwälzanschläge sind jeweils zwei Zapfen vorgesehen. Abgesehen davon, daß die Herstellung der Getriebeglieder verhältnismäßig kompliziert ist, fehlen bei dem bekannten Stempel Geradführungen, die dafür sorgen, daß der Stempeleinsatz nach der Wendung jeweils die richtige Lage beibehält. Es kann nämlich vorkommen, daß einer der die Abwälzanschläge bildenden Zapfen nach der Wendung aus dem zugehörigen Schlitz des Getriebegliedes austritt, zumal ja nur ein ganz kurzer Schlitz- bzw. Kulissenabschnitt für die Geradführung zur Verfügung steht. Eine Verlängerung dieses Abschnittes ist aus konstruktiven Gründen nicht möglich.Such a self-inking stamp is already known (US Pat. No. 4,852,489). The gear members have two symmetrical slots or scenes consisting of a straight and an oblique section. Two pins are provided as rolling stops. In addition to the fact that the manufacture of the gear members is relatively complicated, the known stamp lacks straight guides, which ensure that the stamp insert maintains the correct position after the turn. It can happen that one of the pins forming the roll stops stops the turn exits from the associated slot of the gear link, especially since only a very short slot or link section is available for the straight guidance. An extension of this section is not possible for design reasons.

Der Erfindung liegt daher die Aufgabe zugrunde, den bekannten Selbstfärbestempel so zu verbessern, daß mit vergleichsweise einfachen Mitteln, daß jeweils ein einwandfreies Halten des Stempeleinsatzes nach dem Wenden in der richtigen Lage gesichert ist.The invention is therefore based on the object to improve the known self-inking stamp so that with comparatively simple means that a correct holding of the stamp insert after turning is ensured in the correct position.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die Getriebeglieder am Stempeleinsatz flach U-förmig mit an der Innenseite abgerundeten bzw. abgeschrägten Schenkelenden ausgebildet sind und als Abwälzanschlag jeweils ein einziger zum Stempeleinsatz hin zylindrisch geformter Zapfen vorgesehen ist, der an der Farbkissen- und Aufsetzflächenseite durch Ausnehmungen freigestellt ist, an die zu den Langlöchern parallele Geradführungen für die Schenkelenden des Getriebegliedes anschließen.The invention solves the stated problem in that the gear members on the stamp insert are flat, U-shaped with rounded or beveled leg ends on the inside and as a rolling stop a single pin which is cylindrical towards the stamp insert and is provided on the ink pad and mounting surface side is exempted by recesses, to which straight guides parallel to the elongated holes for the leg ends of the gear link connect.

Die Herstellung der Getriebeglieder ist also verhältnismäßig einfach. Wichtiger sind aber die Geradführungen, die dafür sorgen, daß der Stempeleinsatz nach der Wendung jeweils die richtige Lage beibehält. Dabei können die Geradführungen ohne Schwierigkeiten auch genügend lang ausgeführt werden.The manufacture of the transmission links is therefore relatively simple. But more important are the straight guides, which ensure that the punch insert remains in the correct position after the turn. The straight guides can also be made sufficiently long without difficulty.

a self-inking stamp according to the invention in longitudinal section,
Fig. 2
in cross section along the line II-II of Fig. 1, with the stamp insert in the rest position and

also in cross-section during the turning process of the stamp insert.

Der Selbstfärbestempel besteht aus einem auf die zu stempelnde Fläche aufsetzbaren Unterteil 1, der ein der Aufsetzfläche 2 gegenüberliegendes Farbkissen 3 aufnimmt, aus einem im Unterteil 1 angeordneten, als Druckplattenträger ausgebildeten Stempeleinsatz 4 sowie aus einem Betätigungsteil 5, der den Unterteil 1 mit zwei an dessen Schmalseitenwänden geführten Seitenschenkeln 5a übergreift. Der Betätigungsteil 5 läßt sich gegen die Kraft der Federn 6 zur Aufsetzfläche 2 hin verschieben, wobei an den Enden der Seitenschenkel 5a eine von mit dem Stempeleinsatz 4 einstückigen Schwenkzapfen 7a gebildete Schwenkachse gelagert ist. Die Schwenkzapfen 7a durchsetzen die Schmalseitenwände des Unterteiles 1 in geraden Langlöchern bzw. Längsschlitzen 8.The self-inking stamp consists of a lower part 1 which can be placed on the surface to be stamped and which receives an ink pad 3 lying opposite the placing surface 2, a stamp insert 4 arranged in the lower part 1 and designed as a printing plate carrier, and an actuating part 5 which connects the lower part 1 with two of the other Lateral side walls 5a overlaps. The actuating part 5 can be moved against the force of the springs 6 towards the mounting surface 2, with a pivot axis formed by pivot pins 7a formed in one piece with the stamp insert 4 being mounted at the ends of the side legs 5a. The pivot pins 7a pass through the narrow side walls of the lower part 1 in straight elongated holes or longitudinal slots 8.

Um bei der Hin- und Her- bzw. Auf- und Abbewegung des Betätigungsteiles 5 die gewünschte Wendung des Stempeleinsatzes 4 um 180° zu erreichen, ist jeweils im Bereich der Schmalseitenwände des Unterteiles 1 ein fester, von einem zum Stempeleinsatz 4 hin zylindrisch geformten Zapfen 9 gebildeter Abwälzanschlag vorgesehen, der an der Farbkissen- und Aufsetzflächenseite durch Ausnehmungen 10 freigestellt ist, an die sich Geradführungen 11 anschließen. Am Stempeleinsatz 4 ist jeweils mit Abstand von den Schwenkzapfen 7a in Schmalseitenmitte ein Getriebeglied 12 angeordnet, das flach U-förmig mit an der Innenseite abgerundeten Schenkelenden ausgebildet ist.In order to achieve the desired rotation of the stamp insert 4 by 180 ° during the back-and-forth or up and down movement of the actuating part 5, there is in each case in the region of the narrow side walls of the lower part 1 a fixed pin which is cylindrical in shape towards the stamp insert 4 9 Rolling stop formed is provided, which is free on the ink pad and contact surface side by recesses 10 to which straight guides 11 are connected. On the punch insert 4, a gear member 12 is arranged at a distance from the pivot pin 7a in the narrow side center, which is flat U-shaped with rounded leg ends on the inside.

Wie sich aus den Fig. 2 und 3 ergibt, stößt das Getriebeglied 12 bei der Bewegung des Stempeleinsatzes 4 zur Aufsetzfläche 2 hin, an dem als Abwälzanschlag dienenden Zapfen 9 an und wirkt mit diesem nach Art eines Zahnstangentriebes zusammen, so daß der Stempeleinsatz 4 die gewünschte Wendung durchführt.As can be seen from FIGS. 2 and 3, the gear member 12 abuts during the movement of the stamp insert 4 towards the contact surface 2, on the pin 9 serving as a rolling stop and interacts with it in the manner of a rack and pinion drive, so that the stamp insert 4 takes the desired turn.
