KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Das Neue und Eigentümliche an dem in Fig. ι bis 3 gezeigten Schreibpultsitz ist die Verwendung der Rücklehne / als Hebel, derart, dafs das Näherrücken der Rücklehne Z ein gleichzeitiges automatisches Höherrücken des Sitzes bezw. des Sitzes und des Fufsbrettes zur Folge hat.The new and peculiar thing about the desk seat shown in Fig. Ι to 3 is the Use of the backrest / as a lever in such a way that the backrest Z moves closer simultaneous automatic lifting of the seat respectively. of the seat and the footboard Consequence. Zu diesem Zwecke sind an den zwei Führungen m, in welchen die Seitentheile n, welche den Sitz ο tragen, auf- und abgleiten, die Ellenbogengelenke ρ drehbar angehängt, wovon das kürzere Ende durch Zugstangen q mit der Verbindungssprosse r der Rücklehne, der längere Theil durch Zugstangen t mit dem Sitzrahmen drehbar verbunden ist; das äufserste Ende des längeren Theiles des Ellenbogengelenkes ρ steht weiter mit den Hebeln s in drehbarer Verbindung, in deren unterem Ende ein Draht u ruht, auf welchem das Fufsbrett ν mittelst Winkelträger aufgehängt ist. For this purpose, the elbow joints ρ are attached to the two guides m, in which the side parts n, which carry the seat ο , slide up and down, the shorter end of which is connected by tie rods q to the connecting rung r of the backrest, the longer part is rotatably connected to the seat frame by tie rods t; the outermost end of the longer part of the elbow joint ρ is further in a rotatable connection with the levers s , in the lower end of which rests a wire u , on which the footboard ν is suspended by means of an angular support. Der Draht u hat seine verticale Führung aufserdem in den Schlitzen n> der Führungen m. The wire u also has its vertical guidance in the slots n> of the guides m. Durch dieses Gelenksystem wird bezweckt, dafs ein Hereinrücken der Rücklehne I sofort eine gleichzeitige Hebung des Sitzes, sowie des Fufsbrettes zur Folge hat, und da die verschiedenen Gelenke und Zugstangen in ihrer Länge so bemessen sind, wie es die correcte Stellung von Rücklehne, Fufsbrett und Sitz erfordert, so ergiebt sich von selbst, dafs, wenn die Rücklehne in die für ein 6 jahriges Kind passende nächste Stellung zur Pultkante gerückt wird, Fig. 2, gleichzeitig auf Sitz und Fufsbrett die dieser Körpergröfse entsprechende normale Stellung einnehmen, während umgekehrt bei der entferntesten Stellung die Rücklehne für eine erwachsene Person auf Sitz und Fufsbrett in die passende Lage von selbst zurückfällt, wie durch Fig. 1 veranschaulicht wird.The aim of this articulation system is that moving the backrest I inwards immediately results in a simultaneous lifting of the seat and the footboard, and that the length of the various articulations and tie rods is measured as the correct position of the backrest, footboard and footboard It goes without saying that when the backrest is moved into the next position to the edge of the desk, which is suitable for a 6 year old child, Fig farthest position, the backrest for an adult on the seat and footboard falls back into the appropriate position by itself, as illustrated by FIG. Zur automatischen gleichzeitigen Fixirung von Rücklehne, Sitz und Fufsbrett in jeder bestimmten Lage ist auch hier die oben erwähnte durchlaufende Sperrleiste χ angeordnet, welche in die von den Seitentheilen η angebrachten beiden Zahnleisten y, deren Zähne den verschiedenen Körpergröfsen entsprechen, gleichzeitig einfällt, so dafs also zur ganzen Verstellung und Feststellung von Lehne, Sitz und Fufsbrett ein Druck auf die Rücklehne genügt.For the automatic simultaneous fixation of the backrest, seat and footboard in any particular position, the above-mentioned continuous locking strip χ is arranged here, which falls simultaneously into the two toothed strips y attached by the side parts η , the teeth of which correspond to the different body sizes, so that therefore All that is needed to adjust and lock the backrest, seat and footboard is to press the backrest. Patεντ-Aνspruch:Patεντ-Aνspruch: Ein die Einstellung für verschiedene Körpergröfsen ermöglichender Sitz, bei welchem die Rücklehne (I) mit dem Sitz in solcher Hebel- und Gestängeverbindung (ρ q t) steht, dafs ein Vorschieben der hierbei als Hebel wirkenden Rücklehne das Höherrücken der Sitzfläche bewirkt und wobei mittelst Verlängerung des Kniehebels (p) und Anschlufsgestänges (s) gleichzeitig auch der Fufstritt in den entsprechenden Abstand von der Sitzfläche gerückt werden kann.A seat that enables adjustment for different body sizes, in which the backrest (I) is in such a lever and linkage connection (ρ qt ) with the seat that an advancement of the backrest, which acts as a lever, causes the seat surface to move higher and by means of an extension of the Knee lever (p) and connecting rod (s) at the same time the footstep can be moved to the appropriate distance from the seat.
