KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der Erfindung betrifft eine Vorrichtung zum Feststellen drehbarer und in der Höhe verstellbarer Zeichentische. Die Feststellvorrichtung entspricht im wesentliehen der durch das Patent 142928 geschützten Feststellvorrichtung für Schultafeln und unterscheidet sich von dieser nur dadurch, daß die Drehzapfen an den Endpunkten einer wagerechten Achse angeordnet sind, die mit senkrecht geführten Zahnstangen in Verbindung mit einem Kurbeltrieb steht. Die Drehzapfen c werden in bekannter Weise von den Lagerschalen d, welche durch Stützen n> in Verbindung mit der Tafel stehen, umschlossen, so daß das Zeichenbrett um die Achse i gedreht werden kann.The object of the invention relates to a device for locking rotatable and height-adjustable drawing tables. The locking device corresponds essentially to the locking device for school blackboards protected by the patent 142928 and differs from this only in that the pivot pins are arranged at the end points of a horizontal axis which is connected to a crank drive with vertically guided racks. The pivot pins c are enclosed in a known manner by the bearing shells d, which are connected to the board by supports n> , so that the drawing board can be rotated about the axis i.
Um das Zeichenbrett in der erteilten Schräglage feststellen zu können, sind, wie bei Patent 142928, beiderseits, im vorliegenden Falle an lappenartigen Ansätzen u der Zahnstangen ν Bandbremsen 0 angeordnet, die an ihrem einen Ende fest, aber auswechselbar auf den Ansätzen u sitzen, während ihre freien Enden mittels Schleifen über Zapfen ρ greifen, die auf den kürzeren Armen der doppelarmigen Hebel r angeordnet sind.In order to be able to determine the drawing board in the given inclined position, as in patent 142928, on both sides, in the present case on tab-like extensions u of the toothed racks ν band brakes 0 are arranged, which at one end sit firmly but interchangeably on the extensions u , while grip their free ends by means of loops over pegs ρ , which are arranged on the shorter arms of the double-armed lever r.
Oberhalb der längeren Hebelarme, aber gleichfalls auf den Ansätzen u, sind in bekannter Weise die Exzenterhebel s so angeordnet, daß beim Niederdrücken derselben die Hebelarme r ebenfalls niedergedrückt werden, so daß deren kürzere Arme hochgehen und demgemäß die Bandbremsen anziehen, wodurch die Feststellung des Zeichenbrettes bewirkt wird.Above the longer lever arms, but also on the lugs u, the eccentric levers s are arranged in a known manner so that when they are depressed, the lever arms r are also depressed, so that their shorter arms go up and accordingly the band brakes are applied, thereby locking the drawing board is effected.
