Support chains for a cable guidance device and kit for the end fastening of a support chain

Abstract

Support chain (20) for supporting a cable guidance device (1) comprising a flexible covering (10), wherein the support chain (20) can assume an extended position to form extended sections (5, 6) as well as an arc-shaped position to form a deflection arc (7) and for this purpose comprises a plurality of individual chain links (200) with a longitudinal direction (L) which are pivotably connected to one another, wherein the chain links (200) each have an inner side (220A) and an outer side (220B) with respect to the deflection arc (7), and each comprise a front first longitudinal section (201) and a complementary rear second longitudinal section (202), wherein the second longitudinal section (202) has two side parts (202A, 202B) spaced apart from each other in a transverse direction (Q) transverse to the longitudinal direction (L) and a space (203) between them, characterized in thatthat each chain link (200) of the plurality of chain links (200) has in the first longitudinal section (201) a first receptacle (211) for a pivot pin (213) and in the second longitudinal section (202) a second receptacle (212) for a pivot pin (213), wherein the second receptacle (212) is formed by two coaxial openings (212A, 212B), wherein one of the openings is provided in each of the two side parts (202A, 202B); that for each pair of successive chain links (200), the first longitudinal section (201) of the first chain link is arranged in the free space (203) of the second chain link such that an axis of the first receptacle (211) of the first chain link is aligned with an axis of the second receptacle (212) of the second chain link, wherein the first and the second chain link are pivotably connected to each other by a pivot pin (213) received in the receptacles (211, 212), wherein the pivot pin (213) is in one of the receptacles (211,212) is rotatably mounted; and that the pivot pin (213) can be inserted into the receptacles (211, 212) from both sides in the transverse direction (Q) and can be removed from both sides without damage.
