エネルギー案内チェーン
Document Type and Number:
Japanese Patent JP4028238
Kind Code:
B2
Abstract:
The invention concerns an energy guide chain for guiding hoses, cables or lines comprising chain links (2) each consisting of two link plates (3) and at least one crossbar (8) connecting the link plates, wherein link plates (3) of adjacent chain links (2) have pivot regions comprising mutually corresponding pivot pins (4) and openings (5) for receiving the pivot pins, by means of which the chain links (2) are pivotably interconnected, and wherein the link plates (3) of adjacent chain links (2) have mutually overlapping overlap regions (21, 22), forming lines (6, 7) of link plates, and wherein at least one link plate (3) is provided with a region (15, 20) of weakened material, which permits a variation in length of the link plate line (7) beyond the play which occurs in the pivot region (4, 5) in all directions of the link plate (3). In order to permit improved straight-ahead movement of the chain the material-weakened region (15, 20) is in the form of an elastically deformable region of the link plate (3). The elastic region can be in the form of a cross-sectional constriction of the link plate (3), which extends over the entire height thereof.
