Klapptisch für eine Presse mit einer Sicherheitseinrichtung zum sofortigen Abstützen des Tisches bei Überlast

摘要

The invention consists of a moveable table 1 which rests on a mechanism with two upper pieces 3 and two lower pieces 4, situated on a fixed counter table 2 under which there is an electro-magnet 6, which attracts a counter-weight 5 joined by means of bars 7 to the central ball-and-socket joint of the mechanism in such a way that when the electro-magnet 6 is dis-connected the counter-weight 5 falls, the mechanism folds and the table 1 descends. Under the table 1 and the counter-weight 5, there exist some cylinders and stops (8,11) which damp and limit its descent. The safety mechanism is housed in slots situated under the table 1 and on top of the counter table 2 and its central ball-and-socket joint is formed by the insertion of the lower shaft of the upper piece of the mechanism in the upper half tube of the lower piece of the same mechanism.
