- the guidance of the joint can either be according to Claim 7 by a sled-like guide on a guide rod take place or according to claim 8 by guiding a pin or Nutsteins in a in the bottom of the edition and on the bisector aligned groove.
- the special embodiment of the invention according to claim 9 has the Advantage that the mechanical coupling by means of two swivel plates A particularly precise guidance is guaranteed, which also has high torques can transmit.
- the special embodiment of the invention according to claim 10 has the Advantage that the combination of a gear connection and a Another gear connection ensures particularly precise guidance of the stops is guaranteed during the pivoting movement.
- the device according to Claim 11 has the advantage that by using a Belt connection a permanently reliable and inexpensive guidance of the Sling is guaranteed and in particular the use of a Timing belt further improves the accuracy of the guide.
- the special embodiment of the invention according to claim 12 has the Advantage that by using three appropriately arranged Bevel gears reverse the direction of rotation of the swivel movement of the two Slings with low mechanical play can be realized.
- the bevel gears can also be designed as friction wheels, preferably it is however, according to the embodiment according to claim 13 around conical Gears, which allows the transmission of large torques at the same time precise guidance is guaranteed.
- the special embodiment of the invention according to claim 14 has the Advantage that such a rope, belt or chain guide is constructive is particularly easy to implement.

Die beiden Schwenkscheiben 311, 312 sind um. eine gemeinsame Achse 313 gelagert, aber in verschiedenen Höhen, also in verschiedenen Ebenen parallel zur Grundplatte 301. Um Raum für eine Schwenkbewegung bei gleichzeitigem Mitführen der Anschlagblöcke zur Verfügung zu haben, sind die Zahnscheiben 311, 312 nicht als Vollkreise ausgeführt, sondern beispielsweise als Halbkreise, wobei deren Durchmesser identisch ist. Die näher zur Grundplatte 301 gelagerte erste Schwenkscheibe 311 weist vorzugsweise wenigstens einen Schlitz 307 auf, durch den die Verbindung zwischen der zweiten Schwenkscheibe 312 und deren Anschlagblock geführt ist.
Im dargestellten Ausführungsbeispiel sind alle Schubstangen 452, 453, 456 und 457 von identischer Länge. Möglich ist allerdings auch eine unterschiedliche Länge der Schubstangen, wobei die Schubstangen 452, 453 und 456, 457 jeweils paarweise in ihrer Länge identisch sind.
Das Übersetzungsverhältnis des Riemenantriebs beträgt 1:1. Vorzugsweise ist die Riemenverbindung als Zahnriemenverbindung ausgeführt, d. h. die beiden Riemenscheiben sind Zahnriemenscheiben und der Riemen ist ein Zahnriemen.
Das erste kegelförmige Zahnrad 671 greift in ein zweites kegelförmiges Zahnrad 672 ein, das auf einer Hilfsachse 673 aufgebracht ist, die in der Seitenwand der Anschlagvorrichtung durch ein Gleit- oder Kugellager gelagert ist. Die Hilfsachse 673 des zweiten kegelförmigen Zahnrades 672 schließt mit der ersten Achse 670 einen Winkel von 90° ein. Das zweite kegelförmige Zahnrad 672 greift außerdem in ein drittes kegelförmiges Zahnrad 674 ein, das auf einer Hohlachse 675 sitzt, die koaxial zu der ersten Achse 670 angeordnet ist und diese umschließt. Mit der Hohlachse 675 ist der zweite Schwenkarm 612 und damit über den Führungsschlitz 608 die zweite Anschlagschiene 604 verbunden.
