In addition, this new tripod is less sensitive to shocks and vibrations than the known drawing board tripod ©.

In einer hohlen Standsäule 1, die z.B. von einer Fußplatte getragen sein kann, sind übereinander zwei kurze waagerechte wellen 3 und 4 drenbar gelagert, die darcn zwei miteinander kämmende und auf 3en Wellen 3 und 4 festgekeilte Zahnsektoren 5 und C ge-Kuppelt sind. Auf der oberen V?eile 4, die zweckmäSlgerweise etwas langer als die untere Vleile 3 ist, sind frei drehbar zwei 2w©iarraige Hebel ? gelagert, deren Bnden darch Wellen 8 und 9 miteinander fest verbunden eind.

Claims

T: e 10 rotatably mounted, which engage with their free eyes 11 by means of n in bearings 12 of the drawing board 13. On the ends of the rotating shaft X arms 14 are attached (ζ.Ίϊ. firmly wedged), the Mt eyes 15 by means of wood on bearings 15 el et? Board 13 are stored. The Meigen of the board 13 is normally effected by a support rail 17 which is rotatably mounted on the Vveile S; and in the drawn Peiapiele, a PiagQlklemschrau.be 13 can be fixed in any desired position on the 'tancisüule 1. A weight lever 19 is attached to the shaft 3, which, as shown in FIG. 1, extends towards the boards 13, that is to say lies within the stand frame.

If a change in the board inclination is desired, then also de © loosening the screw 16, the retaining rail 17, which is connected to a Scale can be provided., Pushed into the column 1 or withdrawn from it and then the screw 18 is sucked in again instead of this screw 18, © can also use another means.

The arrangement of the levers 10 and 14 at an obtuse angle on their supports (9 and 4) offers the advantage of increased stability äea drawing board against side bumps.
