Abstract
Abstract A modular element has an internally hollow body (2) made of plasstic material and exhibiting a parallelepiped horizontally-disposed configuration with a transverse section symmetrically diverging from a top portion (4) to a base portion (5). The opposite end surfaces (9, 11) of the body (2) are respectively provided with a coupling lug (8) and an engagement seat (10) matching the shape of said coupling lug. The coupling lug (8) of each modular element (1) is adaped to be fitted in the engagement seat (10) of a contiguous modular element (1b) for the purpose of consecutively connecting several modular elements together. In an alternative embodiment a modular element (12) is provided, at its opposite sides, with two coupling lugs (8) each adapted to be fitted in an engagement seat (10) exhibited by a contiguous modular element (13).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
221 words
A modular element for defining areas and routes on roads and the like, comprising: a plastic body having two opposite side walls joined by two ends, said side walls having a top portion, a base portion and a transverse section symmetrically diverging from said top portion towards a base portion; joining means operating at opposite ends of said body to allow the modular element to be joined with a contiguous modular element; said joining means having at one end a substantially cylindrical coupling lug integral with the plastic body, said cylindrical lug extending from and vertically along said one end surface of said body and having an undercut portion connecting the cylindrical portion with said one end surface, and at the other end a substantially cylindrical engagement seat formed in the other end, said seat extending vertically along said other end and being sized substantially complementary to said coupling lug wherein said coupling lug of said modular element is positively engageable in a pivotable relationship with the engagement seat of a contiguous modular element; each end surface of the body being divided symmetrically into two half parts which diverge from each other to the side walls and form an angle with said side walls whereby a plurality of modular elements can be connected together to form barriers having a curvilinear shape.
