Abstract
The invention relates to an energy guiding chain for guiding cables, hoses and the like with a number of tubular chain links (1) connected together in an articulated manner and designed so that the surface of the top panels (5), bottom panels (2) and at least the transition areas (11) of these panels and the side panels (3, 4) are convexly curved in the circumferential direction of the tubular chain links (1), said chain links each having a bottom panel (5), comprising thereon laterally adjoining, opposite side panels (3, 4) and a top panel (5), whereupon the top panel (5) is detachably connected to the side panels (3, 4), the side panels (3, 4) in each case having a joint pin (6) and a joint opening (7) to connect flexibly, the pivoting angle of both directions of pivot being limited by stops (8) and the top panels (5), side panels (3, 4) and bottom panels (2); of adjacent chain links (1) overlapping telescopically over the entire pivoting angle.
