Description
Mittenmesser.Center knife.
Aufgabe der Erfindung ist es, eine Meßvorrichtung zu schaffen, mit der es ohne weiteres möglich ist, die Mitte einer au messenden Strecke z.B. bei Rahmen aller Art rasch und genau zu ermitteln. Die Aufgabe wird dadurch gelöst, daß 2 MaßbSnder in einem Gehäuse 1 angeordnet sind, die miteinander verbunden und so im .Eingriff miteinander stehen, daß sie nach entgegengesetzten Seiten in Wirkung treten.The object of the invention is to provide a measuring device with which it is easily possible to determine the center of an au measuring distance, e.g. for frames of all types, quickly and accurately determine. The object is achieved in that 2 measuring tape in a housing 1 are arranged, which are connected to each other and are in such a way in engagement with one another that they are in opposite directions Pages come into effect.
Die Vorrichtung ist in der Zeichnung in einem Ausfuhrungsbeispiel dargestellt und es zeigt The device is shown in the drawing in an exemplary embodiment and it shows
Abb. 1 Vorderansieht, zum Teil geschnitten, Abb. 2 Draufsicht,Fig. 1 front view, partially cut, Fig. 2 top view,
Abb« 3 Teilansieht in Draufsicht mit ausgezogenem Maßband, Die Enden des Mittenmessers, d*h. also die Anfangsenden der beiden Maßbänder haben einen winkelförmigen Anschlßg 7 zum Anlegen des Maßbandes. Die Anschläge können sowohl for Innenmessungen eis auch für Außenmessungen Verwendung finden. Maßband und l?eder 3 sind so miteinander verbunden, daß der Anfang des einen mit dem Bnae des andern zusamaienr\£i.ff t. Die Verbindungsstelle ist durch den Punkt angedeutet» JSit der iütteimarkierung 5 kanji man direkt anreißen bzw. mit einem spitzen Gegenstand durch den Schlitz desselben hindurch anreißen, womit die genaue Mitte der rießs trecke ermittelt und markiert wird.Fig «3 Partial view in plan view with the tape measure extended, the ends of the center knife, d * h. so the beginning ends of the two tape measures have an angular connection 7 for applying the tape measure. The stops can be used for both internal and external measurements. Tape measure and length 3 are connected to one another in such a way that the beginning of the one coincides with the bnae of the other. The connection point is indicated by the point "JSit the iüttei marking 5 kanji one directly torn or with a pointed object through the slit of the same, whereby the exact center of the riess route is determined and marked.
Die beiden Maßbänder 2 wickeln sich im Gehäuse spiralförmig auf . Die äußeren Spiralwindungen werden nun durch die Umlenkungen 4, die am Gehäuse befestigt sind, von den übrigen inneren Spiralw&ngen abgehalten, sodaß-"die Zahnräder 6 an diesen Stellen in die Lochverzah*ungen 8 der Maßbänder eingreifen können* Die Zahnrader 6 sind mit den Loehverzahiungen sowie mit sieh selbst dauernd im Eingriff· Daraus ergibt sieh die Wirkungsweise des Mittenmessers* Itird eins der MaßbänderThe two measuring tapes 2 wind themselves spirally in the housing on . The outer spiral turns are now through the deflections 4, which are attached to the housing, from the rest inner spiral walls so that the gears 6 engage in the perforated teeth 8 of the measuring tapes at these points can * The gears 6 are with the Loehverzahiungen as well with see yourself constantly engaged · from this you see the How the center knife works * It is one of the measuring tapes
