ABSTRACT:
In a toggle bar link (100) for conveyor pans of conveyors or guideway pans of extraction machine guideways, with toggle bar sockets (1) arranged at the sides of the pans in whose socket cut-outs (3) a toggle bar can be inserted and retained by securing elements (4), both the toggle bar (2) and the securing elements (4) as well as the toggle bar sockets (1) are constructed intrinsically symmetrically and the toggle bar sockets (1) are arranged symmetrical to a plane of symmetry (S) running through the joint between the pans. Owing to the symmetrical construction of the individual parts they can not only be produced simply but also no orientation problems are posed in the assembly of the individual parts.
