Description
Klammer an Farbbändern zum Auslösen der Umschaltvorrichtung des Farbbandes an der Schreibmaschine Das Umschalten des Sch@reibbandtransportes bei Schreibmaschinen u. dgl. erfolgt in überwiegendem :Maße durch die sogenannte Gabelumschaltung, bei der neben entsprechenden Einrichtungen an der Schreibmaschine, den Umschalthebeln, auch Vorrichtungen am Schreibband selbst erforderlich sind. Diese Umschaltung beruht darauf, daß kurz vor den beiden Endren des Schreibbandes Widerstände irgendwelcher Art angebracht sind, die den Schreibbandu mschalt mechanismus auslösen.Clip on ribbons to trigger the ribbon switching device on the typewriter Switching over the writing tape transport on typewriters and the like takes place predominantly: Measures by the so-called fork switching, at the corresponding devices on the typewriter, the switch levers, devices on the writing tape itself are also required. This switch is based on the fact that just before the two ends of the writing tape resistors of any Kind are attached that trigger the writing tape switch mechanism.
Die vorerwähnten Widerstände an den Schreibbändern sind bisher entweder als Umschaltknöpfe oder als Umschaltösen und auch. als flache, nicht profilierte Umschaltklammern ausgebildet. Diese drei Vorrichtungen haben ganz wesentliche Nachteile. Ihre Befestigung am Schreibband erfolgt entweder so, daß das Band an dieser Stelle durch Unterbrechung der Kett- oder Schußfäden erheblich geschwächt wird (Öse und Knopf), oder indem sie nur an verhältnismäßig kleinen Stellen fest mit dem Schreibband verbunden sind (Knopf und flache Klammer). Diese Nachteile haben zur Folge, daß bei starkem Umschaltzug die Ösen herausfallen oder die Knöpfe bzw. flachen Klammern mit ihren Haltevorrichtungen das Schreibband der Länge nach aufreißen.The aforementioned resistances on the writing ribbons are either as toggle buttons or as toggle eyelets and also. as flat, not profiled Toggle brackets formed. These three devices have very significant disadvantages. They are attached to the writing tape in such a way that the tape is at this point is weakened considerably by interrupting the warp or weft threads (eyelet and Button), or by sticking them with the writing tape only in relatively small places connected (button and flat bracket). These disadvantages have the consequence that If the pulling is strong, the eyelets fall out or the buttons or flat clips Tear open the tape lengthways with their holding devices.
Die Erfindung besteht darin, daß die Umschaltklammern mit Kröpfungen versehen sind, die quer zum Farbband verlaufen.The invention consists in that the switching brackets with offsets are provided that run across the ribbon.
Damit wird der im vorstehenden beschriebene Übelstand beseitigt, weil nunmehr der für die Umschaltung erforderliche Zug durch die Kröpfung der Klammern, mit der einerseits die Klammer am Band unverrückbar befestigt, zum anderen das Band aber weder beschädigt noch geschwächt wird, auf die gesamte Bandbreite verteilt ist. Die Anordnung einer quer zum Farbband gekröpften Umschaltklammer ergibt die Vorteile der sicheren Verbindung von Schreibband' und Umschaltklammer, von gleichmäßiger Verteilung des Zuges auf die gesamte Bandbreite und von störungsfreier Umschaltung des Schreibbandtransportes beim Anlaufen der Umschaltklammer an die Umschaltgabel der Schreibmaschine. Als besonders vorteilhaft hät sich die Erfindung in der Ausführung gezeigt, d'aß die Umschaltklammern das Schreibband von allen Seiten völlig umschließen.This eliminates the drawback described above because now the pull required for the switchover due to the cranking of the clamps, with which on the one hand the clamp is immovably attached to the tape, on the other hand the tape but is neither damaged nor weakened, spread over the entire bandwidth is. The arrangement of a toggle bracket cranked across the ribbon results in the Advantages of the secure connection of the writing tape and the switching clip, of more evenly Distribution of the train across the entire bandwidth and smooth switching of the writing tape transport when the switching clamp starts up against the switching fork the typewriter. The embodiment of the invention is considered to be particularly advantageous shown that the toggle clamps completely enclose the writing tape on all sides.
In der Zeichnung ist eine solche Umschaltklammer dargestellt. Auf dem Schreibband A ist die Klammer B beispielsweise so angebracht, daß das Band auf beiden Seiten von ihr umschlossen wird. Mit C ist die Kröpfung der Umschaltklammer bezeichnet.Such a toggle bracket is shown in the drawing. on The clip B is attached to the writing tape A, for example, in such a way that the tape is on is enclosed on both sides by it. With C is the crank of the toggle bracket designated.
