  • Chain links and cable carrier chains containing same
    Patent number: 6978595
    Abstract: A cable carrier chain having improved strength and flexibility (including improved bilateral flexibility) useful in automotive and other applications contains pivotally joined chain links, each link containing two side plates, two undercut pins, two round apertures which are slightly oversized relative to the pins, a hinged cover lid and a bottom support plate. In the chain, the undercut pins of one chain link are mated with the slightly oversized apertures of an adjacent link, giving the chain increased strength and flexibility. The cover lid preferably includes a hinge member having a relatively thin horizontal strap hinge disposed between two relatively thick vertical hinge straps. The bottom surface of the support plate preferably contains ribs which reduce noise and wear.
