  • Breakdown signal device
    Patent number: 5020466
    Abstract: A breakdown signal device comprises a plurality of at least approximately triangular signal panels (1) hingedly connected to one another by connecting edges (1', 1") so that when not in use they are congruently superimposed and when in use they are deployed in a zigzag manner to form a fence-like barrier. This enables the breakdown signal device to be used in the same way as a breakdown triangle.
