Abstract
Abstract An improved supporting device for wiring of electric cables for an industrial robot is provided which is adapted to house an increased number of electric cables and pipes without making the robot body of a high vertical height or large-sized. The supporting device has plurality of circular spaces divided by axial partition walls each extending along a concentric circle with respect to the rotation axis of the rotary base. A plurality of bundles containing a plurality of electric cables and/or pipe(s) are so installed in each of the circular spaces that each one end of the bundles is secured on the interior wall of the base and then, each bundle extends halfway along a center of one of the circular spaces, and then is turned back to form an U-shaped configuration and returns along a center of opposite circular spaces of the rotary base, and each of the other end of bundles is secured on the rotary base.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
233 words
A supporting device for wiring and piping installed in an industrial robot including a base having a first space and a rotary base having a second space and rotatably mounted on the base; wherein the first space is divided into a plurality of circular spaces by at least one first axial partition wall having a portion extending along a concentric circle with respect to the rotation axis of the rotary base and one end of which is fixed on a bottom wall of the rotary base; and the second space is divided into a plurality of circular spaces by at least one second axial partition wall oppositely disposed with respect to the first axial partition wall via a small space therebetween and end of which is fixed on a ceiling wall of the rotary base; and a plurality of bundles containing a plurality of electric cables and/or pipe(s) so installed in each of the circular spaces so that the one end of each bundle is secured on the interior wall of the base and each bundle extends halfway along a center of one of the circular spaces of the base, and then is turned back to form an U-shaped configuration and returns along a center of the opposite circular space of the rotary base contactably on the ceiling wall thereof, and the other end of each bundle is secured on the rotary base.

Claim 3
Dependent Claim
24 words
The supporting device of claim 1 wherein each bundle containing a plurality of electric cables and/or pipe(s) is housed in a flexible conduit respectively.
Claim 4
Dependent Claim
63 words
The supporting device of claim 1 wherein each bundle containing a plurality of electric cables and/or pipe(s) is housed in a coilspring conduit respectively, further, each of the coilspring conduits are so arranged on both half sides of each circular space that they extend in a symmetrically way with respect to a crossing line passing on the rotation axis of the rotary base.
