Energy guiding chain

摘要

Energy guiding chain, whose chain links (1, 2) each consist of two side straps (3, 4) that are connected to each other by cross-members (5, 6), where the cross-members display a bearing area (7) on at least one of their ends and, seen in the longitudinal direction of the side straps (3, 4), a contact area (9) outside the bearing area. To avoid the accumulation of foreign bodies, the side (11) of the contact area of the cross-members facing from the inside of the chain outwards displays a convex curvature or a linear slope towards its contact surface (10) and encloses an angle of <90° with the inner side (3a, 4a) of the respective side strap, such that the contact surface (10) moves along the inner side of the side strap towards the inside of the chain when the cross-member is pivoted open until a completely opened position is reached.

主权项

1. An energy guiding chain for guiding supply lines from a first connecting point to a second connecting point that moves relative to the first connecting point, comprising:
a plurality of plastic chain links pivotable relative to each other over a pivoting angle, each plastic chain link of the plurality of chain links comprising two side straps, each side strap of the two side straps having an inner side facing towards an inside of the chain, an outer side facing outwards from the chain and opposing narrow faces arranged perpendicular to the inner side and the outer side and extending in a longitudinal direction of the side strap, wherein the side straps form opposite strap strands transverse to the longitudinal direction, wherein at least some of the side straps of the opposite strap strands are connected to each other by a cross-member, wherein at least one end of the cross-member includes a bearing area that interacts with a bearing seat located on a side strap facing towards the end of the cross-member having the bearing area in articulated fashion, for pivoting the cross-member between a closed position and a completely opened position, wherein the at least one end of the cross-member includes, at least one contact area which, in the longitudinal direction of the side strap, is arranged outside the bearing area, the at least one contact area having a contact surface which lies opposite to the inner side of the side strap when the cross-member is in the closed position and having an outer side facing outwards from the chain, wherein the outer side of the at least one contact area facing outwards from the chain comprises a convex curvature or a linear slope upto the contact surface, and encloses an angle of <90° with the inner side of the side strap, such that, when the cross-member is pivoted open to the completely opened position, the contact surface is movable along the inner side of the side strap towards the inside of the chain.
