Portable road sign with panel and base - has two parallel rails with feet and crosspieces to which are fixed hairpin shaped upright

The base of the portable road sign consists of two parallel rails joined by two cross-pieces which are bent at the ends to form four feet. The rails have tubular pieces soldered to them and joined by a cross-bar. Near the tubular pieces in the rails are horizontal axles for brackets on which sleeves are fixed. The support for the sign-board consists of a hair-pin shaped tube the two uprights of which fit into the sleeves so that they can slide in them. The two uprights are connected by a cross-piece preventing the uprights from coming out of the guides. The uprights have a plate to which the sign-board is fixed.
