Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Einrollen eines unter Federwirkung stehenden flexiblen bandartigen Elementes, wie eines Bandmaßes, insbesondere Stahlbandmaßes, einer Schnur, ein Kabels und dergleichen, mit einem Gehäuse oder einem aus Leisten gebildeten Rahmen für das Bandmaß, einem im Gehäuse oder Rahmen vorgesehenen Federantrieb, bestehend aus einer Federhaustrommel, einer spannbaren Feder, einem Federkern und einem mit der Federhaustrommel fest verbundenen Hohlrad mit einer Innenverzahnung, mit einer Aufwickelspule für das Bandmaß, in deren Innenraum mit dem Spulenboden achszentriert ein Ritzel verbunden ist, und mit einem Getriebe, wobei der Federantrieb und das Getriebe in mindesten einem Innenraum der Aufwickelspule zwischen dem Spulenboden und der Wand des Gehäuse oder des Rahmens angeordnet sind.The The invention relates to a device for rolling in a spring action standing flexible tape-like element, such as a tape measure, in particular Steel tape measure, a cord, a cable and the like, with a housing or a frame made of strips for the tape measure, one in the housing or frame provided spring drive, consisting of a barrel drum, a tensionable spring, a spring core and one with the barrel barrel fixed ring gear with internal teeth, with a take-up spool for the Tape measure, a pinion is connected axially centered in the interior of the coil base is, and with a gear, the spring drive and the gear in at least one interior of the take-up reel between the reel bottom and the wall of the case or the frame are arranged.
Die Erfindung setzt sich zur Aufgabe, eine Vorrichtung der oben genannten Art mit einem handlichen, gewichtsmäßig ausgeglichenen, kompakten Aufbau bei zugleich effektivem Antrieb zum Einrollen des flexiblen bandartigen Elementes, wie Bandmaßes, insbesondere Stahlbandmaßes, einer Schnur, eines Kabels und dergleichen zu gestalten.The The invention has for its object a device of the above Kind with a handy, weight-balanced, compact structure with effective drive for rolling in the flexible band-like Element, such as tape measure, especially steel tape measure, a cord, a cable and the like.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß
- – das Getriebe ein Planetengetriebe ist,
- – ein zylindrischer Hohlkörper mit einer Stirnseite fest mit der Wand des Gehäuses oder des Rahmens des Bandmaßes verbunden ist,
- – der zylindrische Hohlkörper an dem zur festgelegten Stirnseite gegenüberliegenden Ende in eine ringsförmige Verlängerung mit einer Innenverzahnung übergeht,
- – wobei ein erster Hohlraum vom Innenmantel des zylindrischen Hohlkörpers und ein zweiter Hohlraum von der Innenverzahnung der ringförmigen Verlängerung umfaßt sind,
- – in dem ersten Hohlraum als spannbare Feder eine Zugfeder und in dem zweiten Hohlraum mindesten ein exzentrisch gelagertes, mit der Innenverzahnung in Eingriff stehendes Planetenrad angeordnet sind, dessen Achse in einem Planetenradträger gelagert ist,
- – das innere Ende der Zugfeder in einem Schlitz des Federkerns gehalten ist, der in der Gehäusewand drehbar gelagert und mit seiner zur letzteren entgegengesetzten Stirnseite mit dem Zentrum des Planetenradträger fest verbunden ist,
- – und die Aufwickelspule auf dem zylindrischen Hohlkörper drehbar gelagert ist derart, daß das achszentriert am Spulenboden befestigte Ritzel der Spule als Sonnenrad mit den Planetenrädern in Eingriff steht.
- - the gear is a planetary gear,
- A cylindrical hollow body with an end face is firmly connected to the wall of the housing or the frame of the tape measure,
- The cylindrical hollow body merges into an annular extension with internal teeth at the end opposite the fixed end face,
- A first cavity is encompassed by the inner jacket of the cylindrical hollow body and a second cavity by the internal toothing of the annular extension,
- A tension spring is arranged in the first cavity as a tensionable spring and at least one eccentrically mounted planet gear is arranged in the second cavity and engages with the internal toothing, the axis of which is mounted in a planet gear carrier,
- The inner end of the tension spring is held in a slot of the spring core, which is rotatably mounted in the housing wall and is fixedly connected to the center of the planet wheel carrier with its end face opposite the latter,
- - And the take-up spool is rotatably mounted on the cylindrical hollow body in such a way that the pinion of the spool, which is axially centered on the spool bottom, engages as a sun gear with the planet gears.
Vorteilhafte Weiterbildung der erfindungsgemäßen Vorrichtung gehen aus den Patentansprüchen 2 bis 11 hervor.advantageous Development of the device according to the invention go from the claims 2 to 11.
Die erfindungsgemäße Vorrichtung erweist sich als praktisch zu handhaben und gewichtsmäßig durch ihren kompakten Aufbau ausgeglichen, wobei die spezielle Kombination von Federantrieb und Planetengetriebe für effetiven Antrieb beim Einrollen des Bandmaßes sorgt.The device according to the invention proves to be practical to handle and by weight their compact structure balanced, taking the special combination of spring drive and planetary gear for effective drive when rolling in of the tape measure provides.
