  • These forces can be influenced in their height as well as in their relation to one another further by the fact that the fastening leg and the locking leg extend at an angle to one another in the direction of the spring plane, so that a tilting of the leg spring results in the area of the vertex arc.
  • Such a set also has the advantage that the legs extend at an angle to each other transversely to the plane of the spring, so that a fixing leg passing through in the vicinity of the vertex arc fastening screw outside the overlapping region of the locking leg and thus is easily accessible.
