The four elements are each provided with protrusions constituted by forks the branches of which are resilient, which are each provided with a recess and with an embossment. These protrusions engage with each other, their embossments and their recesses hooking each other, and are thus articulated to each other around rotation axes. The series of protrusions and of the free spaces which separate them are determined in such a way that the four plates can be articulated to each other two by two, that has for consequence they can be articulated all the four to each other. With respect to a central axis, the half-series of each element are not symmetrical but they can be identical.

[ What is claimed is:] [1.] A set of elements for being interconnected with one another in a mating relationship along rectilinear edges, said set of elements comprising a plurality of separate elements, and each said separate element comprising:a planar member having at least three rectilinear edges, each one of said at least three rectilinear edges having a plurality of teeth supported therealong, said plurality of teeth being located along each of said at least three rectilinear edges in an asymmetrical arrangement, each of said plurality of teeth having a substantially identical shape to one another and said plurality of teeth being irregularly spaced along each one of the at least three rectilinear edges, and each of said plurality of teeth having a width dimension being measured along the rectilinear edge supporting said plurality of teeth;a combined width dimension of all of said plurality of teeth, located along each one of said at least three rectilinear edges, being about one quarter of a total length dimension of each one of said three rectilinear edges to facilitate connection of at least four mating elements with one another along each one of said at least three rectilinear edges; andat least two of said plurality of teeth, provided along any one of said at least three rectilineal edges, being utilized for releasable locking engagement with at least two of said plurality of teeth of a mating element, of said set of elements, for lockingly interconnecting two mating elements with one another.
