FLEXIBLE CURRENT-CONVEYING DEVICE FOR MOVABLE POWER CONSUMER Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: device has box-shaped guide accommodating cable-carrying carriages. Support of each carriage is made in the form of disks of different diameter having spherical surface and mounted in sequence on hanger at different levels. Large-diameter disk is mounted on smooth end of hanger and, when engaging walls and ceiling of guide section, it is set in rotary motion. Small-diameter disk is mounted on section flanges and coupled with hanger through threaded pair. Traction link is secured in hanger hole when small-diameter disk is tightened up, disk proper being locked on hanger in the action. Surfaces of guide flanges contacting small-diameter disk are coated with friction-reducing material, such as organic glass. EFFECT: improved design. 2 cl, 4 dwg
