Abstract
Abstract A cable arranging device for an industrial robot has a cylindrical support casing (2), a swing casing (3) supported on the support casing (2) and swingable about the axis of a swing shaft, and cables (5) interconnecting the swing casing (3) and the support casing (2). One end of a substantially C-shaped cable guide (4) is pivotally supported in the swing casing on the axis of the swing shaft, the other end of the cable guide is pivotally supported in the support casing on the axis of the swing shaft. Spaces for allowing the cable guide (4) to swing therein through a prescribed angle are defined respectively in the swing casing (3) and the support casing (2).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A cable guiding apparatus for an industrial robot, for guiding cables interconnecting a swing shaft swingable through a prescribed angle and a support supporting the swing shaft, comprising: a stationary cylindrical support casing; a rotatable swing casing rotatably supported on said support casing; a cable guide, movable by abutment with the swing casing for moving and guiding the cables and having one end pivotally supported on said swing casing coaxial with said swing shaft and an opposite end pivotally supported in said support casing coaxial with said swing shaft; and openings provided in said swing casing and said support casing, respectively, for allowing said cable guide to swing therein through a prescribed angle.
Claim 2
Dependent Claim
113 words
A cable guiding apparatus for an industrial robot, for guiding cables interconnecting a swing shaft swingable through a prescribed angle and a support supporting the swing shaft, comprising: a stationary cylindrical support casing; a rotatable swing casing rotatably supported on said support casing; a cable guide, movable by abutment with the swing casing for moving and guiding the cables and having one end pivotally supported on said swing casing coaxial with said swing shaft and an opposite end pivotally supported in said support casing coaxial with said swing shaft; and openings provided in said swing casing and said support casing, respectively, for allowing said cable guide to swing therein through a prescribed angle.
Claim 3
Dependent Claim
21 words
A cable guiding apparatus according to claim 1, wherein said swing casing is rotatably supported on top of said support casing.
Claim 4
Dependent Claim
32 words
A cable guiding apparatus according to claim 1, wherein said cable guide has opposite ends and an opening provided near each opposite end through which said cables extend, the ends being rounded.
Claim 5
Dependent Claim
29 words
A cable guiding apparatus according to claim 1, wherein said swing casing and said support casing define an angle through which said cable guide is swung in said openings.
Claim 6
Dependent Claim
50 words
A cable guiding apparatus according to claim 1, wherein said cylindrical support casing has a peripheral wall, a lower wall, and an upper wall, and wherein the upper wall has an arcuate opening of a predetermined arc length for allowing said cable guide to swing therein through a prescribed angle.
Claim 7
Dependent Claim
61 words
