<p>In an ornamental chain, a multiplicity of teeth are arranged in two juxtaposed rows. Each of said teeth has a tooth portion directed toward the other row and arranged to extend between and to interengage with two adjacent teeth of the other row so as to interconnect the rows. Each of said teeth has an end portion on that side of the tooth portion which is remote from the other row. The end portion of each of said teeth of each row comprises two crosspieces, which are spaced apart along the row and extend transversely to a plane containing the chain when it lies on a flat support. A plurality of rings are provided, each of which surrounds two adjacent ones of said crosspieces of adjacent teeth of the same row. The crosspieces and the rings constitute the interconnecting means. Each of the rings connecting the teeth of each row is adapted to interengage with the tooth portion of a tooth of the other row to restrict the movement of the tooth portion transversely to the plane. The end portion of each of the teeth is formed at least on one side with a concave recess. The tooth portion of each of the teeth is formed at least on one side with a convexly curved portion adapted to extend into said concave recess of a tooth of the other row.</p> |
