Abstract
A cable carrier providing substantially complete enclosure of a cable or the like is made up of pivoted, partially-overlapping, hollow rectangular links provided with stop means limiting the degree of flexing permitted in either angular sense. Sheet-like joint closures extend between adjacent links and into pockets at each end of each link, and close the openings otherwise formed between adjacent links when they are pivoted out of alignment.
Claims7
A chain-link type of cable carrier suitable for holding electrical cables, wires, hoses or the like, comprising:
- a plurality of links pivotally connected to each other end-to-end in a series chain;
- each of said links being of integral tubular plastic construction, having a substantially rectangular cross-section at least adjacent its opposite ends to form a box having open ends, and comprising pivot means adjacent each of said opposite ends thereof for providing pivotal connection of each link to immediately adjacent links in said chain;
- one end of each of said links being narrower than its other wider end and the top and bottom of each link having recesses therein adjacent said other end for receiving between its side walls said narrower end of the adjacent link;
- said pivot means of each said link being positioned adjacent but inboard of said opposite end thereof, the pivot axes of said pivot means extending at right angles to said side walls so that when said each link is pivoted about one of its pivot axes in one sense with respect to the immediately adjacent link into which it extends, its pivoting is limited by abutment of the top of said narrower end of each said link against the recessed top of the adjacent link, with the top surfaces of said each link and said adjacent link aligned with each other;
- said pivot means comprising stop means for limiting pivoting of said each link with respect to said immediately adjacent link in the opposite sense at a predetermined angular position to define the minumum permitted radius of curvature of said carrier along its longitudinal axis;
- and
- said links when pivoted toward said predetermined angular position producing an opening between the top surfaces of adjacent links.
A chain-link type of cable carrier suitable for holding electrical cables, wires, hoses or the like, comprising a plurality of hollow links pivotally connected to each other in a series chain;
- each link of said chain being in the form of an open-ended box having a pair of pockets each adjacent one end of said link near its top, each of said pockets having an open end facing toward the adjacent end of its associated link and having a closed bottom opposite from said open end;
- and
- joint closure means extending between the adjacent ends of adjacent links in said chain, with its opposite ends extending into the adjacent confronting pockets of said adjacent links, whereby upon pivoting of one of said links with respect to an adjacent link about an axis such as to separate the bottom of said adjacent links from each other, said joint closure means covers the spacing between the tops of said adjacent pvioted links.
