摘要

The road sign which can be re-erected after a crash comprises a base tube (5) and support tube (4) of the same cross-section. These are connected by metal slides (1) with oblong slots which fit into boxes (3) mounted in the base and support tubes. The slides are made from aluminum alloy or a metal with similar mechanical properties, allowing the sign to be re-erected several times.
