IMPROVEMENTS IN AND RELATING TO CABLE DUCTS AND WALKWAYS

摘要

A cable duct element (28) connectable to another identical element to form a duct made up of elements disposed end-to-end comprises a trough (29) and a cover (30) for covering the trough (29). Mutual angular displacement of neighbouring elements in the duct is allowed by limited gaps in or between the elements. In preferred embodiments, the trough (29) includes a base (33) and side walls (32) upstanding from the base (33). First interlock means (42) are at one end of the trough (29) and second interlock means (46) are at the opposite end. The interlocks of neighbouring troughs cooperate telescopically, a limited gap between the telescoped interlocks permitting angular displacement between the troughs. A cover (30) for the cable duct element (28) includes flexible means cooperable with the cover (30) of a neighbouring element and allowing angular displacement between the elements.
