Die Erfindung bezieht sich auf einen ausziehbaren Heßstab, der mit Hilfe von 7 Segment Anzeigen die gemessene Länge angibt.The invention relates to an extendable measuring rod which indicates the measured length using 7-segment displays.
Der ausziehbare MeßetaD bestehend aus einem flachen aufgeschlitzten Vierkantprofils darin gleitend, ausziehbar ein zweites Vierkantprcfil auf den zur aufgeschlitzten Seite eich die Informationsspur befindet.The extendable measuring device consists of a flat slotted square profile with a second, extendable square profile sliding into it on the slotted side where the information track is located.
Auf dem flachen aufgeschlitzten Vierkantprofils ist die 4 Stellige 7 Segment Anzeige mit Solarzellen und Wasserwaage verschiebbar aufgesetzt.The 4-digit 7-segment display with solar cells and spirit level is mounted on the flat, slit square profile and can be moved.
Schleifkontakte die unmittelbar mit den einzelnen Segmenten der 7 Segement Anzeige verbunden sind, schleifen über der
geeichten Informationsspur und zeigen den direkten Wert an.
Dieser ao Ablsolutmeßetab hat den Vorteil deß im Gegensat?
zu den inkrementalen Meßstfiben bei Stomausfall der Meßwert
nicht verloren geht, sondern bei wiedereinschalten der Versorgung richtig anzeigen wii-d. Auch können bei diesem
Meßstab Störimpulse keinen Meßfehler verursachen. Ferner ist eine Richtungserkennung infolge der absoluten Ablesung der
Schleifkontakte nicht erforderlich.Sliding contacts that are directly connected to the individual segments of the 7-segment display slide over the calibrated information track and display the direct value.
This absolute measuring rod has the advantage that, in contrast to incremental measuring rods, the measured value is not lost in the event of a power failure, but is displayed correctly when the power is switched on again. With this measuring rod, interference pulses cannot cause measuring errors. Furthermore, direction detection is not necessary due to the absolute reading of the sliding contacts.
Der Maßstab besitzt 4 mal 7 Schleifspuren, für jedes Segment eine, deren Abstand in mm Anzeigt. Die Bewegungsrichtung hat auf die Abtasteinrichtung keinen Einfluß, Meßfehler sind ausgeschlossen. Eine Nullstellung ist nicht nötig.The scale has 4 x 7 grinding tracks, one for each segment, the distance between which is shown in mm. The direction of movement has no influence on the scanning device, measuring errors are excluded. A zero setting is not necessary.

Die Erfindung betrifft eine Vorrichtung zum Messen von Weiten und Höhen mittels MsOstab der ausziehbar, digitalisiert ist.The invention relates to a device for measuring widths and heights using an extendable, digitized MsO rod.
Es ist bekannt, daß es auGziahbare Meteretäbe gibt. Es bestand jedoch Bedarf Maßstäbe mit digitalisierter Anzeige und eingebauter Wasserwaage zu konstruieren.It is known that there are extendable measuring sticks. However, there was a need to construct measuring sticks with a digital display and built-in spirit level.
