Abstract
Abstract A cable carrier consisting of a chain with a plurality of links for conveying electric power, water, etc. to the point of application on equipment-in-motion in which each links consists essentially of plastic and includes U-shaped base and U-shaped cover. The cover has a width less than the distance between the pivot axes on the base to allow for sag in the carrier to thus allow a long length carrier to be used. On the other hand, a fixed radius of curvature is provided so that the cable which is carried is not bent excessively.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A multiple cable or hose carrier consisting of a chain with a plurality of links for conveying electric power, water, etc. to a point of application on equipment-in-motion, each of said links consisting substantially of plastic type material and including a U-shaped link base, a U-shaped link cover, said base and cover being adapted to fit together to form a unitary structure said base having first and secon second of pivot means of male and female type construction respectively for coupling to the opposite type pivot means of adjacent links, said pivot means each having a pivot axis, said axes of each base being spaced a predetermined distance which is greater than the width of said cover to allow a chain of several unsupported links to sag, each of said bases having a bight portion whose width is less than said spacing of said axes to provide a fixed radius of curvature when the edges of the bight portions of adjacent links abut.
Claim 2
Dependent Claim
163 words
A multiple cable or hose carrier consisting of a chain with a plurality of links for conveying electric power, water, etc. to a point of application on equipment-in-motion, each of said links consisting substantially of plastic type material and including a U-shaped link base, a U-shaped link cover, said base and cover being adapted to fit together to form a unitary structure said base having first and secon second of pivot means of male and female type construction respectively for coupling to the opposite type pivot means of adjacent links, said pivot means each having a pivot axis, said axes of each base being spaced a predetermined distance which is greater than the width of said cover to allow a chain of several unsupported links to sag, each of said bases having a bight portion whose width is less than said spacing of said axes to provide a fixed radius of curvature when the edges of the bight portions of adjacent links abut.
Claim 3
Dependent Claim
31 words
A carrier as in claim 1 where said bight portions include chamfered edges to provide a smooth interior surface when said edges are abutted to form said fixed radius of curvature.
Claim 4
Dependent Claim
17 words
A carrier as in claim 1 where said female pivot means snap onto said male pivot means.
Claim 5
Dependent Claim
30 words
A carrier as in claim 3 where said bight portions include a pair of slots to allow flexing of said female pivot means when snapped onto said male pivot means.
Claim 6
Dependent Claim
49 words
A carrier as in claim 4 where said female pivot means are offset from the legs of said U-shaped base to provide a torque during longitudinal tension on said chain which tends to bend said female pivot means toward each other into firmer engagement with said male pivot means.
Claim 7
Dependent Claim
34 words
A carrier as in claim 1 where said male pivot means includes a button having a chamfered edge for leading into said female pivot means which include a circular aperture for receiving said buttons.
Claim 8
Dependent Claim
13 words
A carrier as in claim 1 where said covers snap onto said bases.
Claim 9
Dependent Claim
38 words
A carrier as in claim 7 where each of said covers includes a pair of extended tabs for snapping into holes in the legs of said base said tabs having latching means for retaining said cover in engagement.
Claim 10
Dependent Claim
31 words
A carrier as in claim 1 where said pivot axes are offset from said bight portions less than one-half the distance between said bight portion and the top of said cover.
