Description
Die Innenmessungen von Hohlräumen mit dem zur Zeit zur Verfügung stehenden Rollbandmaße sind äußekrst umständlich, d. h. um ein genaues Innenmaß zu bekommen, ist es nötig, zweimal zu messen. The internal measurements of cavities with the currently available standing tape measures are extremely cumbersome, i. H. an exact inside dimension to get it is necessary to measure twice.
Der bisherige Vorgang: Von der einen Innenseite wird zu einem Punkt gemessen, der, wenn möglich, eine runde Zentimetersumme ergeben soll. The process so far: From the one inside becomes a point measured, which, if possible, should add up to a round sum of centimeters.
Dann wird von der gegenüberliegenden Innenseite bis zu dem bei der ersten Messung festgelegten Punkt gemessen. Die sich aus beiden Messungen ergebende Summe ist das gesuchte Innenmaß.Then from the opposite inside to the one at the first measurement. The one resulting from both measurements The sum is the inside dimension you are looking for.
Die Neuerung: Ein Rollbandmaß mit besonderer Maßeinteilung für Innenmessungen soll den oben beschriebenen Mangel beheben. Es ist ein Gebrauchsmaßstab geschaffen, der für Außen- sowie für Innenmessungen geeignet ist. Der Vorteil der Neuerung besteht darin, daß bei Innenmessungen das sich ergebende Maß direkt an der Ablesekante, d.h. an der Rollbandmaßaustrittsäfnung des Rollbandmaßgehäuses abgelesen werden kann. Um dies zu ermöglichen, wird das Rollbandmaßgehäuse als Teil des Maßbandes bei Innenmessungen mit benuitzt und daher in der äußeren Form nicht mehr rund, sondern hufeisenförmig gestaltet. The innovation: a tape measure with special graduation for internal measurements is intended to remedy the deficiency described above. A standard of use has been created which is suitable for external as well as internal measurements. The advantage of the innovation is there in that with internal measurements the resulting dimension is directly on the reading edge, i.e. read from the tape measure outlet opening on the tape measure housing can. To make this possible, the tape measure housing is used as part of the tape measure used for internal measurements and therefore no longer round in the external shape, but shaped like a horseshoe.
Im folgenden ist die Neuerung an Hang der Zeichnung erläutert. In the following, the innovation in the slope of the drawing is explained.
Abb. I alter und neuer Meßvorgang; I, 2, 3 Meßpunkte bei dem üblichen Meßverfahren, 4, 5 Meßpunkte bei dem erfindungsgemäßen Verfahren; Abb. 2 Frontansicht für neue Form (natürliche Größe), 6a hedeutet die Gleitrundung für das Rollband im Innern des Gehäuses; Xbb. 3 Draufsicht mit Maßeinteilung (natürliche Größe). Fig. I old and new measuring process; I, 2, 3 measuring points at the usual Measuring method, 4, 5 measuring points in the method according to the invention; Fig. 2 Front view for new shape (natural size), 6a indicates the sliding rounding for the roll band inside the case; Xbb. 3 Plan view with graduation (natural size).
Das Rollbandmaßgehäuse 6 wird mit der vorgesehenen Anschlagfläche 4 an der einen Innenfläche angeschlagen. Dann wird das Bandmaß 7 so weit ausgezogen, daß der Anfang des rollbandmaßes 5 an der gegenüberliegenden, den iNnenraum bergrenzenden Fläche anschlägt. Das sich dabei ergebende Maß kann dann an der Ablesekante 8, d. h. an der I: ol ll>audmaßaustrittsöffnung, abgelesen werden. The tape measure housing 6 is provided with the stop surface provided 4 posted on one inner surface. Then the tape measure 7 is pulled out so far, that the beginning of the tape measure 5 on the opposite, the inner space bounding Surface strikes. The resulting dimension can then be taken from the reading edge 8, d. H. at the I: ol ll> dimension outlet opening.
Zu diesem Zweck befindet sich neben der für das Anßenmaß vorgesehenen Maßeinteilung 7b von 0 bis 1000 mm oder 2000 mm (2 m) oder auch noch länger noch eine zweite Maßeinteilung 7a, die zum Feststellen von Innenmaßen dient, auf dem Rollhandmaß. Bei der Maßeinteilung für Innenmessungen 7a wird nun, da das Gehäuse 6 selbst als Bandmaßverlängerung dient, die Breite 10 des Rollbandmaßgehäuses von der Bandmaßaustrittsöffnung 8 zur Anschlagfläche 4 des Gehäuses gemessen, zur Bandmaßlänge g hinzugezählt, so daß sich für das Innenmaß der Gesamtstrecke 1 1 ergibt und deshalb zweckmäßig die Maßeinteilung 7a für Innenmaße nicht mit omm, sondern mit dem der Breite des Rollbandmaßgehäuses entsprechenden Maß, z. B. mit 5 cm, beginnt. Dies ist aus der Abb. 3 ersichtlich.For this purpose there is next to the one provided for the measurements Graduation 7b from 0 to 1000 mm or 2000 mm (2 m) or even longer a second graduation 7a, which is used to determine internal dimensions, on the Rollhand measure. With the graduation for internal measurements 7a, the housing 6 itself serves as a tape measure extension, the width 10 of the tape measure housing of measured from the tape measure outlet opening 8 to the stop surface 4 of the housing, to the tape measure length g added, so that 1 1 results for the inner dimension of the total distance and therefore appropriately the graduation 7a for internal dimensions not with omm, but with that of the Width of the tape measure housing corresponding dimension, z. B. starts with 5 cm. this can be seen from Fig. 3.
Der am Anfang des Rollbandmaßes befindliche, als Anschlag für Außenmessungen dienende Haken wird bei Innenmessungen hinzugezählt, z. B. Rollbandmaßgehäuse 5 cm, Anschlaghaken I mm: daraus ergibt sich 51 mm. Mit dieser Zahl beginnt das Bandmaß für Innenmessungen. Es kann bei der Herstellung unter Umständen auch eine andere Anfangszahl für die Maßeinteilung für Innenmessungen notwendig werden, z. B. für größere Gehäusebreite oder größere Materialstärke des Anschlag hakens. Das Maß wird aber vom Messenden ohne Addieren oder Subtrahiere ohne weitres abgelesen, ist, also für jedermann brauchbar. The one at the beginning of the tape measure as a stop for outside measurements serving hooks are added to internal measurements, e.g. B. Tape measure case 5 cm, stop hook I mm: this results in 51 mm. The tape measure begins with this number for inside measurements. It may also be a different one during manufacture Initial number for the graduation for internal measurements are necessary, e.g. B. for greater housing width or greater material thickness of the stop hook. The measure will but read from the measuring person without adding or subtracting without further information, is, therefore usable for everyone.
