Description

[0041] The characteristics of the new base and of the brackets are highlighted in greater detail in the following description, making reference to the drawings which are attached hereto by way of non-limiting example.

[0042] FIG. 1 shows a top view of a possible embodiment of the new base (B), while

[0043] FIG. 2 shows a view of the same base (B) from below.

[0044] FIG. 3 shows a three-dimensional view of the base (B) shown in FIGS. 1 and 2.

[0045] The new base (B) comprises a plane portion (B1) suited to be rested and fixed to the ground. Said plane portion (B1) can be provided with one or more holes for the insertion of fixing means suited to fix the base (B) to the ground.

[0046] Said plane portion (B1) has an upper surface (B11) from which a raised portion (B2) extends upwards, said raised portion (B2) being preferably tubular and more preferably cylindrical, and suited to be connected with the other parts of a support for raised floors such as, for example, an intermediate body and/or the upper head (T) on which the floor panels rest (FIG. 8).

[0047] Said plane portion (B1) has at least one rectilinear edge (B3) which is close and preferably tangential to said tubular portion (B2).

[0048] Said rectilinear edge (B3) can be usefully placed beside a vertical obstacle, for example a step, a wall or a riser, to obtain a step of the raised floor.

[0049] For example, said plane portion (B1) has a substantially circular shape, without a circular segment defined by said rectilinear edge (B3), which thus is substantially a chord of the circular shape.

[0050] In a preferred solution, said plane portion (B1) comprises also at least one partial rectilinear notch or precut or cut (B4), for example traced on its underside (B12) shown in FIG. 2, and wherein said notch (B4) defines a detachable circular segment (B41).

[0051] Said rectilinear notch (B4) is preferably orthogonal to said rectilinear edge (B3), in such a way that, once said detachable circular segment (B4) has been removed, a straight angle, useful to position the base (B) in proximity to a corner, is defined on said plane portion (B1).

[0052] Even said rectilinear notch (B4) is tangential or in any case close to said tubular portion (B2).

[0053] The figures also show how said plane portion (B1) may comprise even openings or seats (B32, B42) for the engagement or coupling of fixing brackets (S) shown in FIGS. 4 and 5, respectively in a side sectional view and in a three-dimensional view.

[0054] Said fixing brackets (S), for example, can be used to constrain a riser (A) to said base (B) to obtain a step.

[0055] Said fixing bracket (S) comprises a plane portion (S1) suited to be rested on the ground under said plane portion (B1) of said base (B), a first end (S2) shaped with tabs or projections (S21, S22) for the engagement of the lower edge of a riser (A), indicated by a broken line in FIG. 4, a second opposite end (S3) shaped with a tooth or raised part or tab (S31) suited to be inserted in one of said openings or seats (B32, B42) of said base (B).

[0056] For example, said tab (S31) is bent in the shape of a C.

[0057] Said openings or seats (B32, B42) are preferably and conveniently created in said plane portion (B1) of the base (B) in a diametrically opposite position with respect to said rectilinear edge (B3) and said notch (B4), if any, since said brackets (S) must be positioned with said first end (S2) resting on said rectilinear edge (B3) or on said notch (B4), if any.

[0058] Furthermore, said base (B) preferably comprises, on said rectilinear edge (B3), a recess (B31) suited to accommodate said first end (S2) of said bracket (S). In this way, the bracket (S) is positioned in a stable manner with respect to the base (B).

[0059] The support for raised floors comprises a base (B) suited to be rested on the ground as described above, and at least one upper head on which panels for raised floors can be rested, said head being directly or indirectly constrained to said base (B), for example through one or more intermediate or additional bodies, and wherein said head can be fixed and/or rotate and/or oscillate with respect to said base (B).

[0060] The support comprises also at least one of said fixing brackets (S) as described above.

[0061] FIG. 4 shows a sectional view of the lower bracket (S) only, while FIG. 5 shows a three-dimensional view of the same lower bracket (S).

[0062] FIG. 6 shows a sectional view of the upper bracket (P) only, while FIG. 7 shows a three-dimensional view of the same upper bracket (P).

[0063] FIG. 8 shows a possible embodiment of a head (T) of the new support.

[0064] Said head (T) has a substantially flat upper surface (T1) on which the floor panels can be directly or indirectly rested. Partitions (T2) extend upwards from said upper surface (T1), for example four radial partitions (T2), preferably detachable. Said upper surface (T1) of the head (T) can possibly be provided with damping inserts.

[0065] Said head (T) can be of the fixed, rotary, oscillating or non-oscillating type.

[0066] The lower fixing bracket (S) is preferably made of a metallic material.

[0067] Said tabs or projections (S21, S22), for example, are obtained by bending parts of said first end (S2) towards the same side, and they are intended to be oriented upwards in such a way as to form a U-shaped seat (S4) for the insertion and engagement of said lower edge (A1) of said riser (A).

[0068] Said tabs (S21, S22), for example, are shaped in such a way as to elastically retain the edge (A1) of the riser (A).

[0069] Said lower bracket (S) is thus positioned in a stable manner between the ground and the base (B).

[0070] The upper fixing bracket (P) (FIGS. 6, 7) is preferably made of a metallic material and comprises a flat part (P1) suited to be rested on the upper surface (T1) of said head (T), and a first end (P2) shaped with first tabs or projections (P21, P22) for the engagement of the upper edge (A2) of a riser (A), indicated by a broken line in FIG. 4.

[0071] Said first tabs or projections (P21, P22), for example, are obtained by bending parts of said first end (P2) towards the same side, and they are intended to be oriented downwards in such a way as to form a seat (P4) for the insertion and engagement of said upper edge (A2) of said riser (A).

[0072] Said first tabs (P21, P22), for example, are shaped in such a way that they elastically retain said upper edge (A2) of the riser (A).

[0073] According to the invention, said upper bracket (P) may also comprise, on said first end (P2), a further tab (P23) bent on the opposite side with respect to said first tabs (P21, P22) and suited to come into contact with the edge (F1) of an upper floor panel (F), as indicated by a broken line in FIG. 6.

[0074] Said further tab (P23) is preferably aligned with said first more external tab (P21), so that said edge (F1) of the upper panel (F) can be aligned with said riser (A).

[0075] Said plane portion (P1) of said upper bracket (P) is furthermore provided with one or more holes (P3) suitable for the insertion of said partitions (T2) of said head (T), indicated by a broken line in FIG. 7.

[0076] Preferably, said upper bracket (P) comprises two of said holes (P3), aligned and suitable for the insertion of two corresponding aligned partitions (T2), in such a way that said upper bracket (P), once correctly positioned, can neither rotate nor move with respect to the head (T).

[0077] Therefore, with reference to the above description and to the attached drawings, the following claims are expressed.
