Device for establishment of support displaying e.g. ascending genealogy, has smaller layers superimposed on base support to allow continuous filiations of smaller layers in set of fractionated sequences of genealogical arborescences

摘要

The device has a base support (1) on which a set of smaller layers (2) are superimposed to allow continuous filiations of smaller layers in a set of fractionated sequences of genealogical arborescences. The layers are superimposed for folding of the base support. The support is broader than the set of smaller layers once the support is folded, where a beginning of a branch of the layers is in continuity with an end of a tree structure of the support.
