Sheet support for lattice receptacle, such as cable tray, has blocking spline rotating by bending between standby position and blocking position, where spline is in plane perpendicular to wire in blocking position

摘要

The support has a principal body (7) with an upper edge (8) comprising a slot (12) that receives a rigid wire. A blocking spline (13) is situated towards an opening of the slot. The spline rotates by bending between a standby position and a blocking position. The spline is in a plane perpendicular to the wire in the blocking position. The spline is connected to the body by a bending line parallel to the slot. The slot extends between the opening and a closed end. The spline leads the slot (12) freely in the standby position, and obstructs the slot (12) in the blocking position. An independent claim is also included for a cable tray comprising sheet support and a lattice receptacle.
