    Abstract: A duct (10) is made up of a plurality of layers (11, 12, 13) of pliant material. The layers (11, 12, 13) are attached by stitching (20, 22) to form pockets (23, 24) between adjacent layers. One of the layers (11) is wider than the others and extends over the lateral edges (17, 19) of those layers (12, 13), and when the stitching (22) is applied, a loop (21) is formed. The loop (21) receives a strength member (26) which may be engaged by a clamp (31) carried by a bracket (34) which may be attached to a utility pole (30) to carry the duct (10) overhead. In another embodiment, a duct (40) includes enclosed loops (41, 42, 43) forming pockets (50, 51, 52). Stitching (54) connects the loops (41, 42, 43) and forms another loop (55) to receive a strength member (56). In yet another embodiment, the layers (61, 62, 63 and 64) are of different lateral widths, and the longest layer (64) extends around one of the edges of the other layers (61, 62, 63) to form a loop (71) when stitching (65) is applied. The loop (71) receives the strength member (73).

    Abstract translation: 管道（10）由多个柔顺材料层（11,12,13）构成。 层（11,12,13）通过缝合（20,22）附接以在相邻层之间形成凹穴（23,24）。 层（11）中的一个比其他层（11）宽，并且在这些层（12,13）的横向边缘（17,19）上延伸，并且当施加缝合（22）时，形成环21。 回路（21）接收强度构件（26），该加强构件可被由支架（34）承载的夹具（31）接合，该支架可附接到电线杆（30）以承载管道（10）。 在另一个实施例中，管道（40）包括形成袋（50,51,52）的封闭环（41,42,43）。 缝合（54）连接环（41,42,43）并形成另一个环（55）以接收强度构件（56）。 在另一个实施例中，层（61,62,63和64）具有不同的横向宽度，并且最长层（64）围绕其它层（61,62,63）的边缘之一延伸以形成环 （65）施加时（71）。 回路（71）接收强度构件（73）。
