A foldable guide sign assembled substantially into the shape of a triangular pyramid in use, wherein two planes (S1, S2), among three planes (S1, S2, S3) in adjacent with the apex (P) of the substantially triangular pyramid are formed each with an integral plate (2, 3) respectively, the integral plates (2, 3) being connected inwardly collapsably, and the remaining one plane (S3) has bisected plates (5R, 5L) split substantially in a right-to-left symmetrical shape connected collapsably with each other, each of the bisected plates (5R, 5L) is connected inwardly collapsably to each of the adjacent integral plates (2, 3) respectively. When each of the bisected plates (5R, 5L) is enforced to the inside of the triangular pyramid, the integral plates (2, 3) connected on both ends thereof overlap with each other and collapsed into the size of one integral plate (2, 3). Upon use, since the guide sign is assembled into the sterical shape of the substantially triangular pyramid, it is extremely stable and less turned down even if a window is blown strongly from any direction. <IMAGE> |
