Spacer block device for maintaining insulating sheet e.g. glass wool, at distance from electric equipment carrier of luminaries in suspended ceiling, has reversed U-shaped bridges comprising elements for stocking at flat position

摘要

The device (1b) has reversed U-shaped bridges (3b) supported on an electric equipment carrier (2) so as to maintain an insulating sheet (Is) at a distance (d) from the electric equipment carrier. The bridges comprise elements e.g. molded plastic elements such as hinges, to be stocked at flat position. Each element has a thickness lower than 4 mm or 10 mm in a flat position (P1) of the element. The bridge includes elements that include a flexible hinge (6) allowing storage of the elements in a flat position of the elements.
