Title: (EN) Length-variable sliding rail element for a roller chain
Abstract: front page image
(EN)

A length-variable sliding rail element enables a roller chain to be easily guided. Two complementary sliding rail elements fit together. Each of the sliding elements may be comprised of two or three segments. These various segments interengage each other to form a sliding rail element that is shiftable between collapsed and extended position.
