Abstract (en)
[origin: EP0165229A2] In order to secure the position of tongue blades (3, 4) of railway points, an arm (9, 10) of a knee lever (7, 8) is coupled to each tongue blade (3, 4). The other arm (12, 13) of the respective knee lever (7, 8) engages on an energy store (14) which is common to both knee levers (7, 8), each knee lever (7, 8) being mounted at the point of intersection of its arms to a fixed swivel axle (6). The line of action of the force of the energy store (14) is located at both end positions of the knee lever (7, 8) on different sides of the swivel axle (6), the end position of each knee lever (7, 8) being defined by stops (16, 17). <IMAGE>
