Description

Rechenscheibe mit stählernem Bandmaß. Man hat bereits kreisförmige Rechenschieber, sogenannte Rechenscheiben, bei denen die Skalenträger in einem Gehäuse untergebracht sind, mit einem ebenfalls in dem Gehäuse angeordneten Bandmaß ausgerüstet. Gemäß der Erfindung wird das in an sich bekannter `'eise aus Stahl bestehende Bandmaß am inneren Ende mit einer Verstärkung versehen und durch -den auch sonst bei Bandmaßen üblichen Schlitz in der Gehäusewandung hindurchgeführt, wobei sich die weiter unten beschiieLenen besonderen Wirkungen ergaben.Calculating disk with a steel tape measure. One already has circular ones Slide rules, so-called slide rules, in which the scale carriers are in a housing are housed, equipped with a tape measure also arranged in the housing. According to the invention, the tape measure, which is known per se, is made of steel Provided with a reinforcement at the inner end and through -th also otherwise with tape measures usual slot in the housing wall, which is further down indicated special effects.

Auf der Zeichnung ist ein Ausführungsbeispiel der Rechenscheibe im Achsenschnitt dargestellt. Die Rechenscheibe ist oben mit gegeneinander verschiebbaren geteilten Scheiben i und 2 und außen mit dem Gehäuse 3 versehen. Unten kann zweckmäßig ein Boden .I vorgesehen sein. Durch einen Schlitz 5 der Gehäusewandung ,; ragt das aus Stahlland versehene Bandmaß(-) nach außen heraus. Am inneren Ende i,-,.t das Bandmaß Ü mit einer abgerundeten Verstärkung 7 ver::ehen, welche einerseits das gänzliche Herausziehen desselben aus dem Gehäuse verhindert, anderseits das gute Gleiten im Innern des Gehäri@cs beim Einschieben des Bandmaßes, in dasselbe ermöglicht. Das äußere Ende des Bandmaße>> ist mit einer Öse <8 o. dgl. zum Anfassen zwecks Herausziehens versehen. Zum Gebrauch kann das Bandmaß herausgezogen und nach dem Gebrauch wieder durch den Schlitz 5 in das Innere des Geh-iuses,; eingc:#cljoben werden, wobei es sich durch seine federnde Spannung von selbst an der Innenseite der Gehäusewandung entlang führt.In the drawing, an embodiment of the disk rule is in Axial section shown. The calculating disc rule is at the top with mutually displaceable divided disks i and 2 and provided with the housing 3 on the outside. Down can be functional a bottom .I may be provided. Through a slot 5 in the housing wall; that protrudes tape measure (-) provided from Stahlland to the outside. At the inner end i, - ,. t that Provide tape measure Ü with a rounded reinforcement 7, which on the one hand has the it is prevented from being pulled out of the housing completely, on the other hand the good Sliding inside the Gehäri @ cs when inserting the tape measure, in the same made possible. The outer end of the tape measure >> is with an eyelet <8 or the like for the purpose of touching Pulling out. For use, the tape measure can be pulled out and after Use again through the slot 5 in the interior of the housing; eingc: #cljoben it is self-contained on the inside due to its elastic tension the housing wall leads along.

Es kt:nnte indes auch im Innern des Gehäuses eine niecrige Trommel vorgesehen sein, auf welche das Banc.maß in geeigneter Wehe aufgewickelt wer(#cn kann. Ferner kann das Bandmaß auch außen herum um das Gehäuse gewickelt werden, zu welchem Zwecke das eine Ende an dem Gehäuse befestigt wC!rC.e, und wobei oben und unten zur vorteilhaften Einlagerung des Bandmaßes ringsum verlaufende Ansätze vorgesehen sein können.There could, however, also be a small drum inside the case be provided, on which the bank measure is wound up in a suitable woe (#cn can. Furthermore, the tape measure can also be wrapped around the outside of the housing, for what purpose one end attached to the housing wC! rC.e, and with above and at the bottom for the advantageous storage of the tape measure, all-round approaches can be provided.
