Selective anchoring device for raised floors

Selective anchoring device for raised floor sections formed by tiles placed side by side with the formation of interposed joints comprising:

• at least one support (2) for at least one said section made with at least two component parts (3, 4) opposite each other along a line (5) transversal to the floor, a first component part (3) of the support (2) being suitable for joining monolithically to said at least one section, the other part (4) being secured by a structure outside said support;
• said component parts (3, 4) comprising plates (9, 10) opposite each other, oriented parallel to the floor plane, one (9) of which includes a combination of geometric solids with vertices (13) converging towards said transversal direction (5) and suitable for supporting a said floor partition;
• joining means (6) associated with these component parts (3, 4) and switchable when appropriately controlled between two limit conditions;
• actuating means (7) for the switching of said joining means (6);
• and
• control means (8) for the actuating means (7), operating at a distance from the joining means (6);
• the device is being characterized in that
• said joining means (6) are interposed between the plates (9, 10), said geometric solids having the shape of a three-dimensional, cylindrical segment, with parallel base surfaces (14) of a trilateral mixtilinear shape, surrounded by lateral sides oriented transversely to the walking surface of the floor, said three-dimensional segments having their vertices (13) off-center with respect to said transversal direction (5) in such a way as to implement, with its sides, side banks of said joints;
• and in that said joining means (6) comprises
• at least one cavity (12) inside a said three-dimensional segment, located between said base surfaces (14) and located near the top opening of the joints, the sides of said geometric solid being provided with at least one window (11) oriented orthogonally to the walking surface and suitable for giving access to the internal cavity (12);
• and
• at least one bolt (15), which is movable horizontally between said limit conditions in the first of which is engaged in the cavity (12) traversing said at least one window (11), with said plates (9, 10) correspondingly interconnected and constrained to each other at least in the two directions along said transversal line (5) joining these component parts (3, 4) and inhibiting at least their relative longitudinal mobility along said transversal direction (5);
• in the second limit condition, said bolt (15) being instead disengaged from the cavity (12) of said geometric solid, and located inside a said joint with said component parts (3, 4) of the support (2) disjoined and separable from each other.
