Patent number: 7674065Abstract: A device for locking end positions of switch parts, having two parts, relatively axially displaceable and positively coupled in at least one direction, including a tube and a rod guided within the tube, at least partially arranged in an outer tube. Locking members cooperate with the parts and outer tube and are displaceable into a locking position in the outer tube's recess. Locking members include ring segments chamfered on insides forming first abutment surfaces converging obliquely toward rod axis. First abutment surfaces cooperate with oblique counter abutment surfaces in a rod recess for holding the rod and the tube coupled during the rod's first displacement path and for urging segments outwardly to emerge from rod recess, and to slide onto the rod's outer surface adjacent rod recess and to immerse into locking position in the outer tube's recess upon rod movement relative to the tube over a second displacement path.Type: GrantFiled: July 31, 2002Date of Patent: March 9, 2010Assignees: VAE Eisenbahnsysteme GmbH, VAE GmbHInventors: Karl Schnedl, Herbert Achleitner, Josef Hörtler
