Description
Rechenschieberläufer Die Erfindung bezieht sich auf einen Rechenschieberläufer, insbesondere für einen doppelseitigen Rechenschieber. Aufgabe der Erfindung ist, eine einfache Form eines solchen Läufers zu schaffen. Es ist bereits ein solcher Läufer bekanntgeworden, der aus zwei jeweils die Ober- und die Unterseite des Schiebers bedeckenden durchsichtigen Teilen besteht, die lösbar miteinander verbunden sind. Erfindungsgemäß wird eine für das Spritzgußverfahren geeignete Ausführung vorgeschlagen, die dadurch gekennzeichnet ist, daß die beiden Teile in der gleichen Spritzgußform herstellbar und ihre Verbindung durch längsgerichtete Keile und Nuten erfolgt.Slide rule runner The invention relates to a slide rule runner, especially for a double-sided slide rule. The object of the invention is to create a simple form of such a runner. It is already one Runner has become known, which consists of two each, the top and bottom of the slide covering transparent parts which are detachably connected to one another. According to the invention, an embodiment suitable for the injection molding process is proposed, which is characterized in that the two parts are in the same injection mold can be produced and their connection is carried out by means of longitudinal wedges and grooves.
Ein Ausführungsbeispiel gemäß der Erfindung ist im folgenden an Hand der Zeichnung im einzelnen erläutert. Es zeigt Fig. 1 ein abgebrochen dargestelltes Schaubild eines Rechenschiebers mit einem Läufer gemäß der Erfindung, Fig. 2 eine Stirnansicht eines Läuferteiles, Fig. 3 eine Stirnansicht eines teilweise im Schnitt dargestellten Läufers.An embodiment according to the invention is given below the drawing explained in detail. 1 shows a broken line Diagram of a slide rule with a runner according to the invention, FIG. 2 a Front view of a rotor part, FIG. 3 is a front view of a partially in section depicted runner.
In der Zeichnung ist ein als Ganzes mit 1 bezeichneter Läufer für einen doppelseitigen Rechenschieber 2 dargestellt. Der Läufer besteht aus zwei gleichen Teilen, wobei jeder Teil als Winkelstück ausgebildet ist, dessen kurzer Schenkel 4 an einer Seitenfläche 3 des Rechenschiebers 2 und dessen als ebene Platte ausgebildeter langer Schenkel 5 an einer Frontfläche 3' des Rechenschiebers anliegt. Der kurze Schenkel 4 weist eine einseitige Schwalbenschwanznut 6 auf-, und der dem kurzen Schenkel 4 abgewandte Rand des langen Schenkels 5 ist als Keilleiste 5' mit einem einseitigen, der Nut 6 des kurzen Schenkels entsprechenden Schwalbenschwanzprofil ausgebildet. Der ganze Teil 4, 5 ist dabei aus einem durchsichtigen Kunststoff hergestellt. Der kurze Schenkel 4 weist eine nach außen gewölbte Außenfläche 4' auf, die zur besseren Handhabung geriffelt sein kann.In the drawing, a runner, designated as a whole by 1, for a double-sided slide rule 2 is shown. The runner consists of two equal parts, each part being designed as an elbow, the short leg 4 of which rests on a side surface 3 of the slide rule 2 and the long leg 5 of which is designed as a flat plate rests on a front surface 3 'of the slide rule. The short leg 4 has a one-sided dovetail groove 6, and the edge of the long leg 5 facing away from the short leg 4 is designed as a wedge bar 5 'with a one-sided dovetail profile corresponding to the groove 6 of the short leg. The whole part 4, 5 is made of a transparent plastic. The short leg 4 has an outwardly curved outer surface 4 ' which can be corrugated for better handling.
Beim Zusammensetzen des Läufers werden zwei Teile 4, 5, wie in Fig. 3 dargestellt, so zusammengesetzt, daß jeweils die Keilleiste 5' des einen Teiles in die Schwalbenschwanznut 6 des anderen Teiles eingreift. Um die beiden Teile gegeneinander festzustellen, ist in jeder Keilnutverbindung 5', 6 eine in eine Bohrung 7 eingreifende Schraube 8 vorgesehen.When assembling the rotor, two parts 4, 5, as shown in FIG. 3, are put together in such a way that the wedge bar 5 'of one part engages in the dovetail groove 6 of the other part. In order to fix the two parts against each other, a screw 8 engaging in a bore 7 is provided in each keyway connection 5 ′, 6.
Damit sich der Läufer 4, 5 am Rechenschieber 2 nicht von selbst verschiebt, ist in an sich bekannter Weise zwischen dem kurzen Schenkel und der Seitenfläche 3 des Rechenschiebers eine gebogene Blattfeder 9 vorgesehen, deren abgebogene Enden die inneren Endkanten des kurzen Schenkels 4 umfassen und die dadurch am Herausfallen gehindert ist.So that the rotor 4, 5 on the slide rule 2 does not move by itself, is in a manner known per se between the short leg and the side surface 3 of the slide rule a curved leaf spring 9 is provided, the bent ends of which encompass the inner end edges of the short leg 4 and thereby prevent them from falling out is prevented.
