Cable protector
A cable protector including a series of generally cylindrical shells, with adjacent shells pivotable relative to each other; and a support member extending through the shells. The support member holds the shells so that the shells cannot be separated from each other. The support member includes arm sections, corresponding to the shells, connected by flexible linear sections extending along a central axis of the shells. Each arm section includes a base connected to the linear section, and a plurality of arms extending radially outward at equal angles. Each arm has a first end connected to the base, and a second end connected to a surface of the shell toward the central axis.
1. A cable protector comprising:
a series of generally cylindrical shells, with adjacent shells pivotable relative to each other; and
a support member extending through the shells, the support member holding the shells so that the shells cannot be separated from each other, the support member comprising arm sections, corresponding to the shells, connected by flexible linear sections formed of a softer plastic, and extending along a central axis of the shells, each arm section comprising a base connected to a corresponding flexible linear section, and a plurality of arms extending radially outward at equal angles, each arm having a first end connected to the base, and a second end connected to a surface of the shell facing toward the central axis, each arm section comprising a skeleton formed of a harder plastic, and a covering portion formed of the same softer plastic as the flexible linear sections, the covering portion covering at least part of the surface of the skeleton, and the covering portion being molded unitary with the linear section.
2. The cable protector of claim 1 , each shell comprising an outer shell section having an inner surface defining part of a first sphere, and an inner shell section having an outer surface defining part of a second sphere, the outer and inner shell sections abutting axially of the cylindrical shell, each pair of adjacent shells being arranged such that the inner shell section of a first of the adjacent shells bears against the outer shell section of a second of the adjacent shells, and the center of the second sphere of the inner shell section of the first shell coincides with the center of the first sphere of the outer shell section of the second shell, and the linear section being positioned such that the coinciding sphere center falls on the central axis of the linear section.
3. The cable protector of claim 1 , each arm including a lockable portion at the second end, and each shell including corresponding locking portions on a surface facing toward the central axis, the locking portions of the shells engaging the lockable portions so that the shells are connected to the support member.
4. The cable protector of claim 3 , each shell comprising at least one opening/closing circumferential segment making a cable accessible to inside from outside, the at least one opening/closing segment having a first circumferential end including one of the locking portions, and a second circumferential end including a hinge pin extending parallel to the central axis, the opening/closing segment being connected at the second circumferential end to another segment of the shell by the hinge pin, allowing the opening/closing segment to be opened and closed.
