Abstract
Abstract The device comprises at least one reflective flag carried by a lateral rod in its turn carried by a lower bracket. The bracket is constituted by a strip of stainless steel sheet or other weather-resistant material, shaped as an arcuate hairpin for gripping the upper part of the guard rail resiliently. In one embodiment, the flag is mounted on the rod so as to be pivotable and is biassed by a spring into a position in which it projects towards the carriageway. Preferably the flag includes a frame in which replaceable reflective sheets are inserted.

Claim 11
Dependent Claim
39 words
Device as defined in claim 9, characterised in that the spacer member is a rigid bush which prevents rotation of the flag by virtue of the clamping of the lugs between the head of the rod and the bush.
Claim 12
Dependent Claim
35 words
Device as defined in claim 10, wherein the rod is of such a length as to receive two opposing flags and including a further spacing bush interposed between the adjacent lugs of the two flags.
Claim 13
Dependent Claim
65 words
Device as defined in claim 9, characterised in that the flag is pivotable on the rod by means of its lugs, and the spacer member includes a hairpin spring wound helically around the rod under the lower lug and having arms which engage the flag so as to urge it resiliently to a position in which it projects from the guard rail towards the carriageway.
Claim 14
Dependent Claim
