Description

Bei Füllbleistiften mit einer die Schreibmine vordrückenden Schubstange ist es bekannt, die Blokkierung und den Transport der Schubstange mit Hilfe einer auf , der Schubstange sitzenden Eckscheibe, auch Klemmglied genannt, zu bewerkstelligen. Bei den bekannten Anordnungen ragt ein die Eckscheibe tragender Bedienungshebel seitlich aus dem Bleistiftschaft heraus. Dieser Bedienungshebel ist in zweierlei Hinsicht ungünstig. Einmal setzt er die Handlichkeit des Bleistiftes beim Schreiben herab, und zum anderen ist seine Handhabung noch etwas umständlich, da für Vor- und 1Zücktransport der Mine zwei entgegengesetzte Druckrichtungen am Bedienungshebel erforderlich sind.In the case of filling pencils with a push rod that pushes the lead forward it is known to block and transport the push rod with the help of a on, the push rod seated corner disc, also called the clamping member, to accomplish. In the known arrangements, an operating lever carrying the corner pane protrudes sideways out of the pencil shaft. This operating lever is twofold In terms of unfavorable. For one thing, he uses the handiness of the pencil when writing and on the other hand, its handling is still a bit cumbersome, since and 1 return transport of the mine two opposite directions of pressure on the operating lever required are.

ach der Erfindung werden diese Nachteile vermieden, wenn die Bedienung der Eckscheibe mit Hilfe eines Druckknopfes am Bleistiftkopf erfolgt.According to the invention, these disadvantages are avoided if the operator the corner disc is done with the help of a push button on the pencil head.

Die Abbildung gibt eine solche Ausführungsform wieder. Der Bleistiftkörper i enthält die Schreibmine 2, die ihrerseits von der Schubstange 3 blokkiert bzw. transportiert wird. Zum Eckscheibenmechanismus gehören außer der Schubstange die Eckscheibe4 mit dem radialen Arm 5, die Friktionsbüchse 6 und die Feder 7. Der am Bleistiftkopf befindliche Druckknopf 8 besteht aus einem Rohr, welches leicht spielend in dem Bleistiftkörper beweglich ist. Der Eckscheibenarm 5 ragt durch eine Bohrung des Druckknopfrohres bis hinein in eine Bohrung 9 des Bleistiftkörpers. Die Schubstange trägt zwecks zentrischer Führung eine Platte io. Der Mechanismus arbeitet folgendermaßen: Zum Vortransport der Schreibmine wird der Druckknopf 8 bis zum Anschlag in den Bleistiftkörper hineingedrückt. Bei diesem Vorgang bewegt der Druckknopf 8 den Eckscheibenarm 5, die Eckscheibe d. und infolge der Eckwirkung der Eckscheibe auch die Schubstange 3 mitsamt der ?Mine 2 in Richtung auf die Bleistiftspitze, bis durch die Auflage des Eckscheibenarms 5 auf der vorderen Wandung der Bohrung 9 der Anschlag gegeben ist. Beim Freilassen des Druckknopfes tritt die Eckwirkung nicht ein, und die Feder 7 drückt die Eckscheibe und den Druckknopf gleitend über die Schubstange in die Ausgangslage zurück, während die Schubstange infolge der Reibkraft der Friktionsbüchse 6 in ihrer neuen vorgeschobenen Stellung verbleibt.The figure shows such an embodiment. The pencil body i contains the refill 2, which in turn is blocked or blocked by the push rod 3. is transported. In addition to the push rod, the corner disc mechanism includes the Eckscheibe4 with the radial arm 5, the friction bush 6 and the spring 7. The am Pencil head located push button 8 consists of a tube, which is easy to play is movable in the pencil body. The corner disc arm 5 protrudes through a hole of the push-button tube into a hole 9 in the pencil body. The push rod carries a plate io for the purpose of centric guidance. The mechanism works as follows: To advance the lead, the push button 8 is pushed into the pencil body as far as it will go pressed in. During this process, the push button 8 moves the corner disk arm 5, the corner disc d. and as a result of the corner effect of the corner disc, the push rod as well 3 together with the? Lead 2 in the direction of the pencil tip until through the support given the corner disc arm 5 on the front wall of the bore 9 of the stop is. When the push button is released, the corner effect does not occur, and so does the spring 7 pushes the corner panel and the push button sliding over the push rod into the Starting position back, while the push rod due to the frictional force of the friction sleeve 6 remains in its new advanced position.

Zum Rücktransport der Schreibmine kann bei gedrücktem Druckknopf die Mine mitsamt der Schubstange zurückgeschoben werden, weil der Anschlag des Druckknopfes bzw. des Eckscheibenarms die Eckwirkung aufhebt.To transport the refill back, the Mine together with the push rod are pushed back because the stop of the push button or the corner disc arm cancels the corner effect.
