Vorrichtung zum Heben und Senken des Vorlagerahmens von Zeichentischen.
Die den Gegenstand vorliegender Erfindung bildende Vorrichtung hat den Zweck, das lIeben und Senken des Vorlagerahmens von Zeichentischen zu erleichtern.
EMI1.1
in teilweisem Schnitte und in einer Vorderansicht und in Fig. 2 in einer Seitenansicht dargestellt.
Der Vorlagerahmen a dieses Tisches ist in zwei Führungen 1 verschiebbar und kann in den verschiedenen Stellungen auf folgende Art und Weise fixiert werden :
Mit dem unteren Rande 2 des Rahmens ist ein Drahtseil 5 verbunden, das über eine feste Rolle 4 und eine lose Rolle 5 geführt ist, worauf es an der Tischplatte befestigt ist. Die lose Rolle 5 ist an einem zweiarmigen Hebel 7 angeordnet, der um den
EMI1.2
in welchem sich der Zapfen einer Schraubenmutter. 9 verschiebt. Durch diese Schrauben- mutter geht eine Schraubenspindel 10 bindurch, welche drehbar in einer Stütze 11 und in der Tischplatte gelagert ist.
Dreht man die Schraubenspindel mittels der Kurbel 1L', so wird dadurch der Hebel 7 um den Punkt 'verdreht und der Rahmen unter Vermittlung des Seiles gehoben oder gesenkt.
Durch diese Vorrichtung wird überdies nicht allein nur das Heben und Senken, sondern auch die Feststellung des Rahmens in seiner jeweiligen Lage erzielt, da infolge
EMI1.3
hindert wird.

Device for raising and lowering the template frame of drawing tables.
The device forming the subject of the present invention has the purpose of facilitating the lifting and lowering of the template frame of drawing tables.
EMI1.1
shown in partial sections and in a front view and in Fig. 2 in a side view.
The template frame a of this table can be moved in two guides 1 and can be fixed in the various positions in the following way:
With the lower edge 2 of the frame, a wire rope 5 is connected, which is guided over a fixed roller 4 and a loose roller 5, whereupon it is attached to the table top. The loose roller 5 is arranged on a two-armed lever 7 around the
EMI1.2
in which there is the pin of a nut. 9 moves. A screw spindle 10, which is rotatably mounted in a support 11 and in the table top, passes through this screw nut.
If the screw spindle is rotated by means of the crank 1L ', the lever 7 is thereby rotated around the point' and the frame is raised or lowered by means of the rope.
Through this device, not only the raising and lowering, but also the fixing of the frame in its respective position is achieved, as a result
EMI1.3
is prevented.
