Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Einrollen eines unter Federwirkung stehenden flexiblen bandartigen Elementes, wie eines Bandmaßes, insbesondere Stahlbandmaßes, einer Schnur, eines 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, mindestens einer spannbaren Zugfeder, einem Federkern und einem mit der Federhaustrommel fest verbundenen Hohlrad mit einer Innen- oder Außenzahnung, mit einer Aufwickelspule für das Bandmaß, in deren Innenraum mit dem Spulenboden achszentriert ein Ritzel verbunden ist, und mit einem Getriebe, vorzugsweise einem Planetengetriebe, wobei das Hohlrad von der Zugfeder beaufschlagbar ist und die Aufwickelspule in Bezug auf das Hohlrad derart drehbar gelagert ist, daß das achszentriert am Spuleboden befestigte Ritzel der Spule mit dem Getriebe in Eingriff steht, gemäß der deutschen Patentanmedldung 103 06 340.4-22.The The invention relates to a device for rolling a spring action standing flexible belt-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, a in the case or frame provided spring drive, consisting of a barrel drum, at least one tensionable tension spring, a spring core and a ring gear firmly connected to the barrel drum with an inner or external teeth, with a take-up reel for the tape measure, in the interior with the coil bottom axis-centered a pinion is connected, and with a transmission, preferably a planetary gear, wherein the ring gear is acted upon by the tension spring and the take-up reel in relation to the ring gear is rotatably mounted so that the axis-centered at the bottom of the spool mounted pinion of the coil with the gear engaged stands, according to the German Patent Application 103 06 340.4-22.
Bei größeren Bandmaßlängen von z.B über 10 Metern ist das Vorsehen eines zweistufigen Planetengetriebes in der Vorrichtung angebracht. Da jedoch bei der oben genannten Vorrichtung Teile des Federantriebs und des Getriebes im Innenraum der Spule angeordnet sind und mit einer Vergrößerung des Durchmessers der Federhaustrommel auch ein größeren Innendurchmesser der Aufwickelspule notwendig ist und somit das Gewicht und das Volumen des Gehäuses der Vorrichtung ansteigen, ergibt sich die Zielstellung der vorliegenden Erfindung, eine Vorrichtung der eingangs erwähnten Art so zu gestalten, daß eine Abhängigkeit des Innendurchmessers der Spule vom Durchmesser bzw. der Größe der Federhaustrommel vermieden wird und die Möglichkeit eines Variieren des Innendurchmessers der Federhaustrommel je nach der Länge des verwendeten Bandmaßes gegeben ist. Insbesondere soll zugleich beim Betrieb der Vorrichtung mit dem mehrstufigen Planetengetriebe ein Zurückschnellen des Bandmaßes verhindert und für einen kompakten Aufbau der Vorrichtung mit effektivem Antrieb gesorgt werden.at larger tape lengths of Eg over 10 Meters is the provision of a two-stage planetary gear in attached to the device. However, as with the above device Parts of the spring drive and the transmission in the interior of the coil are arranged and with an increase in the diameter of the Barrel drum also has a larger inside diameter the take - up reel is necessary and thus the weight and the volume of the housing increase the device, the objective of the present results Invention to design a device of the type mentioned above so that a dependency the inner diameter of the coil of the diameter or the size of the barrel drum is avoided and the possibility varying the inside diameter of the barrel drum depending on the length the used tape measure given is. In particular, at the same time during operation of the device With the multi-stage planetary gear prevents the tape measure to snap back and for provided a compact construction of the device with effective drive become.
Diese Zielstellungen werden erfindungsgemäß durch die im Patentanspruch 1 beschriebene Vorrichtung erreicht.These Goals are inventively by the in claim 1 device achieved.
Vorteilhafte Weiterbildungen der erfindungsgemäßen Vorrichtung gehen aus den Patentansprüchen 2 bis 4 hervor.advantageous Further developments of the device according to the invention go from the claims 2 to 4 show.
Die Erfindung bringt den Vorteil mit sich, daß die Aufwickelspule nicht durch das Gewicht der mindestens einen Zugfeder belastet wird, so daß für den Antrieb der Aufwickelspule und damit zum Einrollen des Bandmaßes nur eine verhältnismäßig geringe Federkraft benötigt wird.The Invention has the advantage that the take-up reel is not is loaded by the weight of at least one tension spring, so that for the drive the take-up reel and thus to curl the tape measure only a relatively low spring force needed becomes.
Vorteilhafte Ausführungsformen der erfindungsgemäßen Vorrichtung werden nun anhand der Zeichnungen erläutert. In diesen sind:advantageous embodiments the device according to the invention will now be explained with reference to the drawings. In these are:
