Multi-compartment aerial duct

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 ).

1 . A duct comprising a plurality of enclosed loops positioned adjacent to each other, none of the loops having a common wall, an additional loop formed by one of said loops, and a strength member received in said additional loop.  
   
   
       2 . A duct comprising a plurality of separate enclosed loops positioned adjacent to each other, means to attach said loops so that one of said loops is formed with a second loop positioned outside of all of said loops, and a strength member received in said second loop.  
   
   
       3 . A device adapted to carry a plurality of cables or the like comprising a plurality of separate pockets, each pocket being made of a pliant material and having a first end, an opposed second end, and sides between said first and second ends, said pockets being attached to each other near said first ends to form compartments.  
   
   
       4 . A device adapted to carry a plurality of cables or the like comprising a plurality of separate enclosed pockets made of a pliant material, none of said pockets having a common wall, said pockets being positioned adjacent to each other, and means to attach said pockets to each other thereby forming a compartment in each pocket, each compartment being adapted to receive a cable.  
   
   
       5 . A device adapted to carry a plurality of cables or the like comprising a plurality of separate pockets, each said pocket being formed from adjacent layers of a pliant material joined at at least one end, said pockets being positioned adjacent to each other and having their layers attached to each other and to an adjacent pocket near the other of said ends to form compartments.
