Abstract

A separation duct for encompassing an elongate member. The duct includes longitudinal internal spacers extend longitudinally in a direction of a longitudinal axis of the duct. A longitudinal plane for each spacer is substantially parallel to the longitudinal plane of the other spacers. The spacers support the elongate member and resist slippage of the duct relative to the elongate member. The duct may be used to provide separation and protection for elongate members of a range of outside dimensions.

First claim

What is claimed is:

1. A separation duct segment configured to be combined with at least one additional separation duct segment for encompassing an elongate member, the separation duct segment comprising:
an elongate body having an outer surface and an inner surface, the outer surface and the inner surface being bridged at ends thereof by associated mating faces; and
a plurality of spacers extending inwardly away from the inner surface, each spacer extending longitudinally from a location adjacent a first end of the elongate body in a direction toward a second end of the elongate body, wherein a longitudinal plane associated with each of the spacers is substantially parallel with a longitudinal plane associated with the other ones of the spacers, the longitudinal plane associated with each of the spacers being a plane extending along a length of the spacer and through a top and bottom of the spacer.

2. A separation duct segment according to claim 1 , wherein the longitudinal plane associated with each of the spacers bisects the spacer.

3. A separation duct segment according to claim 1 , wherein the spacers have different heights.

4. A separation duct segment according to claim 1 , wherein first one of the spacers closest to one of the associated mating faces has a height greater than second one of the spacers furthest from the one of the associated mating faces.

5. A separation duct segment according to claim 1 , wherein the spacers do not extend inwardly beyond the mating faces.

6. A separation duct segment according to claim 1 , wherein an end surface of each of the spacers is flush with an end surface of the elongate body.

7. A separation duct segment according to claim 1 , wherein the spacers are resiliently deformable.

8. A separation duct segment according to claim 1 , wherein the spacers have a generally triangular shape.

9. A separation duct segment configured to be combined with at least one additional separation duct segment for encompassing an elongate member, the separation duct segment comprising:
an elongate body having a semi-annular cross-section with a convex semi-circular outer surface and a concave semi-circular inner surface, the outer surface and the inner surface being bridged at ends thereof by associated mating faces; and
a plurality of spacers extending inwardly away from the inner surface and extending longitudinally from a location adjacent a first end of the elongate in a direction toward a second end of the elongate body, the spacers being resiliently deformable and a first one of the spacers closest to one of the associated mating faces has a height greater than second one of the spacers furthest from the one of the associated mating faces, wherein a longitudinal plane associated with each of the spacers is substantially parallel with a longitudinal plane associated with the other ones of the spacers, the longitudinal plane associated with each of the spacers being a plane bisecting the spacer and extending along a length of the spacer and through a top and bottom of the spacer.

10. A separation duct for encompassing an elongate member, the separation duct comprising:
an outer surface, an inner surface and a central cavity; and
a plurality of spacers extending inwardly away from the inner surface at intervals along a length of the duct, each spacer extending longitudinally in a direction of a longitudinal axis of the duct, wherein a longitudinal plane associated with each of the spacers is substantially parallel with a longitudinal plane associated with the other ones of the spacers, the longitudinal plane associated with each of the spacers being a plane extending along a length of the spacer and through a top and bottom of the spacer.

11. A separation duct according to claim 10 , wherein the longitudinal plane associated with each of the spacers bisects the spacer.

12. A separation duct according to claim 10 wherein the spacers have different heights.

13. A separation duct according to claim 10 , wherein the spacers are resiliently deformable.

14. A separation duct according to claim 10 , wherein the spacers have a generally triangular shape.

15. A separation duct according to claim 10 , the duct further comprising a second plurality of spacers extending inwardly away from the inner surface in opposing facing relationship to the plurality of spacers at the intervals along a length of the duct, the second plurality of spacers extending longitudinally in a direction of a longitudinal axis of the duct, wherein a longitudinal plane associated with each of the second plurality of spacers is substantially parallel with a longitudinal plane associated with the other ones of the second plurality of spacers, the longitudinal plane associated with each of the second plurality of spacers being a plane extending along a length of the spacer and through a top and bottom of the spacer.

16. A separation duct according to claim 15 , wherein the plurality of spacers and the second plurality of spacers are provided at an area of reduced external dimension of the duct.

17. A separation duct according to claim 16 , wherein a tension band is provided around the duct at the area of reduced external dimension to compress the plurality of spacers and the second plurality of spacers against an elongate member.
