Abstract
Abstract A road edge marker comprising a reflector support divided into two aligned portions joined together by means of a hinge which allows the two portions to shift in case of collision. The hinge consists of sleeves fixed to said portions, connected to one another by an elastic member, such as a spring or a caoutchouc tube, which brings them back to their original position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
Anti-collision road marker characterized in that it comprises, within a tubular support consisting of at least two portions, an elastic joint connecting one of said portions to the other, said joint including: a first sleeve (7,28) fixed coaxially and internally in a rigid way to one end of the first portion (5) and projecting slightly form said end; a second sleeve (8,27) fixed coaxially and internally in a rigid way to one end of the second portion (6) and indenting slightly from said end; engagement means (11,12; 42,43) on the first and second sleeve for their reciprocal engagement so as to define their precise relative position; and an elastic member (13,25) engaged with the first and second sleeves so that said first and second portions remain aligned while the first and second sleeves are engaged with one another, and disalignment of said portions is allowed by the giving of said elastic member, the return force of which brings the road marker back to its initial position.
Claim 2
Dependent Claim
166 words
Anti-collision road marker characterized in that it comprises, within a tubular support consisting of at least two portions, an elastic joint connecting one of said portions to the other, said joint including: a first sleeve (7,28) fixed coaxially and internally in a rigid way to one end of the first portion (5) and projecting slightly form said end; a second sleeve (8,27) fixed coaxially and internally in a rigid way to one end of the second portion (6) and indenting slightly from said end; engagement means (11,12; 42,43) on the first and second sleeve for their reciprocal engagement so as to define their precise relative position; and an elastic member (13,25) engaged with the first and second sleeves so that said first and second portions remain aligned while the first and second sleeves are engaged with one another, and disalignment of said portions is allowed by the giving of said elastic member, the return force of which brings the road marker back to its initial position.
Claim 3
Dependent Claim
24 words
Road marker according to claim 1, in which said elastic member is a small tube of vulcanized natural caoutchouc (13) which operates on traction.
Claim 4
Dependent Claim
29 words
Road marker according to claims 1 and 2, in which said portions (5,6) and said caoutchouc tube are joined rigidly to said sleeves by means of pins (9,10; 14,15).
Claim 5
Dependent Claim
147 words
Road marker according to claim 1, in which said elastic member is a helical spring (25) which operates by compression and also includes: an upper plug (26) and a lower plug (29) equipped with two opposite longitudinal grooves (32,35) in the cavities of the upper and lower sleeves respectively and fixed with respect to them; a flexible and traction resistant ring-shaped cable (31) placed to run along said grooves of said plugs; a screw (47) fixed to the upper end of said ring-shaped cable; a support (24) equipped with an opening for said screw; and a nut (23) engaged with said screw and with the upper surface of said support, said screw resting on the lower surface of said support and above the upper sleeve so that a relative aiä p lacement of the upper and lower portions of the road marker causes compression of said spring.
Claim 6
Dependent Claim
32 words
Road marker according to any of the preceding claims in which said engagement means (11,12; 42,43) on said sleeves are a pair of tapered projections and indentations exactly opposite to one another.
Claim 7
Dependent Claim
30 words
Road marker according to any of the preceding claims, in which the sleeve orojectiong from the end of the respective portion is equipped with a flange which covers said end.
Claim 8
Dependent Claim
18 words
Road marker according to any of the preceding claims, in which said tubular support is of circular section.
Claim 9
Dependent Claim
36 words
Road marker according to any of the preceding claims comprising a flattened spade-shaped point (50), equipped laterally with a saw tooth profile (52), with openings (54) in its surface and a hook (53) near the point.
