Definitions

  • the present patent concerns the supports used for raised floors, and more specifically it concerns a new support for raised floors with bases and possibly with fixing brackets for vertical elements.
  • the supports for raised floors are usually constituted by a base resting on the ground, a substantially cylindrical or tubular intermediate body which extends upwards from said supporting base and a head on said intermediate body, said head having a flat upper surface on which the panels or the elements making up the floor are laid.
  • the size of said flat upper surface of the head is usually such as to allow the comers or part of the panels to be rested thereon side by side, thus forming the floor.
  • damping and sound insulation elements which are positioned on said upper surface of the head.
  • Said damping elements comprise, for example, layers of elastic material having a thickness of a few millimeters.
  • Supports whose height is not adjustable are known, in which said base, said intermediate body and said head are a single element.
  • Supports are also known in which, to compensate the differences in gradient between the ground, which often must be inclined to ensure the drainage of rainwater, and the raised floor, which must be horizontal, the lower surface of said head is convex and suited to oscillate in a corresponding concave seat created on the top of said intermediate body.
  • the adjustment or compensation of the inclination between the panels of the raised floor and the ground is thus carried out by adjusting the inclination of the head in the concave seat in the intermediate body.
  • Supports are also known, instead, in which the head is configured to be coupled with said intermediate body in such a way that it cannot oscillate but only rotate around the longitudinal axis of the intermediate body.
  • Supports with adjustable height are also known, in which said base and said intermediate body are configured to be screwed on each other in an adjustable manner, consequently varying the overall height of the support.
  • Supports with adjustable height are also known which, in addition to said intermediate body, comprise also a further body serving the function of an extension, having a generically tubular shape, too, and provided with a thread or other constraining means for the coupling with said intermediate body and said head, and for the adjustment of the overall height of the support.
  • the height of the supports is adjusted by acting on said intermediate body or on said extension body through a screwing/unscrewing action or in any case by acting on said constraining means.
  • said head is usually holed axially, so that the operator can insert a screwing tool therein through said hole.
  • the flat upper surface of the head of the known supports may comprise vertical partitions, usually four and substantially orthogonal to said flat upper surface, arranged radially towards the centre of the circular shape of said upper surface, that is, arranged on the axes of symmetry of the surface itself to define the four straight angles for the positioning of the corners of the floor panels.
  • the supports are distributed on the surface to be floored: the base is rested on and in some cases fixed to the ground, said intermediate body is coupled with said base and said head is coupled with said intermediate body.
  • Said base generally comprises a plane portion resting on the ground and a tubular portion, normally cylindrical, which extends upwards from said plane portion and is intended to be coupled with said intermediate body or with said additional bodies, if any, or directly with said head.
  • Said plane portion resting on the ground can be holed, so that it can be constrained to the ground.
  • the support’s base is usually circular and this causes some drawbacks if the support’s base must be positioned in proximity to an obstacle, for example a vertical wall or a step.
  • the raised floor to be made often comprises also one or more steps, formed by panels arranged vertically to form the risers of the steps.
  • Said risers must be constrained to the ground and to the upper horizontal panels which make up the floor.
  • L-shaped brackets are known, for example made of a metallic material, which are used to fix a riser to a support. More specifically, for example, each riser is constrained to at least one support by means of a first bracket constrained between the lower edge of the riser and the base of the support and by means of a second bracket constrained between the upper edge of the riser and the head of the support. In order to be able to position the riser and the support correctly, therefore, the support must be very near the riser and this is not possible due to said enlarged plane portion of the base.
  • a new type of base for supports for raised floors has been designed and carried out, which comprises an especially shaped plane portion suited to be rested on the ground.
  • the main object of the present invention is to simplify the procedures for the assembly of raised floors, thus optimizing the time required to lay said floors.
  • the new base for supports for raised floors comprising at least one plane portion suited to be rested and fixed to the ground, and a raised portion, usually tubular and preferably cylindrical, joined to and extending upwards from said plane portion, and wherein said plane portion is shaped with at least one edge which is at least partially rectilinear and tangential or in any case close to said tubular portion.
  • said plane portion has a substantially circular shape without a circular segment, wherein said tubular portion, which is preferably cylindrical, is substantially concentric with said plane portion, and wherein the chord or secant which defines said missing circular segment is tangential or in any case close to said tubular portion.
  • said plane portion comprises also a rectilinear cut or notch, orthogonal to said chord of the circular segment and defining a further detachable circular segment on said plane portion.
  • said plane portion has a substantially circular shape without two circular segments, wherein said tubular portion, which is preferably cylindrical, is substantially concentric with said plane portion, and wherein said two circular segments are defined by respective chords which are orthogonal to each other.
  • said plane portion has at least one straight angle, suited to be positioned, for example, at the level of a comer or of an angle.
  • the new base can be used on any type of support for raised floors, and in particular on supports comprising said base, a possible intermediate body and a possible additional body, and an upper head, oscillating or not, on which the floor panels can be directly or indirectly rested.
  • the support for raised floors may also comprise fixing brackets for vertical elements such as, for example, the risers of steps or vertical panels.
  • the new support comprises at least one lower bracket suited to constrain the lower edge of a riser to said base of the support, and/or at least one possible upper bracket suited to constrain the upper edge of a riser to said head of the support, and wherein said constraint is obtained without using screws or other fixing means.
  • Said lower bracket comprises a plane portion suited to be rested on the ground under said base, that is, suited to be interposed between the ground and said base.
  • Said lower bracket comprises a first end shaped with tabs or projections facing sideways and intended to be oriented upwards for the engagement of the lower edge of a riser, and a second opposite end shaped with a tooth or raised part suited to be inserted in a corresponding opening or seat created in the plane portion of said base.
  • Said lower bracket if correctly positioned, is thus positioned in a stable manner with respect to said base, which in its turn can be fixed to the ground according to the known technique.
  • Said lower bracket in fact, is constrained between the ground and the base, said first end rests on the edge of said plane portion of the base, while said second end is coupled in said opening or seat made in said plane portion of the base.
  • said upper bracket comprises a plane portion suited to be rested on the upper surface of said head, and a first end shaped with tabs or projections facing sideways and intended to be oriented downwards for the engagement of the upper edge of a riser.
  • said plane portion preferably comprises one or more holes or seats for the insertion of said partitions extending upwards from said upper surface of said head.
  • Said upper bracket if correctly positioned, is thus positioned in a stable manner with respect to said head.
  • Said upper bracket in fact, is constrained between the head and the panels of the floor, while the partitions of said head, inserted in said holes of the upper bracket, prevent the latter from moving accidentally.
  • said upper bracket comprises at least two holes made in said plane portion, so that at least two of said partitions can be inserted therein, making the orientation of the bracket stable.
  • Figure 1 shows a top view of a possible embodiment of the new base (B), while Figure 2 shows a view of the same base (B) from below.
  • Figure 3 shows a three-dimensional view of the base (B) shown in Figures 1 and 2.
  • the new base (B) comprises a plane portion (Bl) suited to be rested and fixed to the ground.
  • Said plane portion (Bl) can be provided with one or more holes for the insertion of fixing means suited to fix the base (B) to the ground.
  • Said plane portion (Bl) has an upper surface (Bl 1) 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 (Figure 8).
  • Said plane portion (Bl) has at least one rectilinear edge (B3) which is close and preferably tangential to said tubular portion (B2).
  • 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.
  • said plane portion (Bl) 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.
  • said plane portion (Bl) comprises also at least one partial rectilinear notch or precut or cut (B4), for example traced on its underside (B12) shown in Figure 2, and wherein said notch (B4) defines a detachable circular segment (B41).
  • 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 (Bl).
  • the figures also show how said plane portion (Bl) may comprise even openings or seats (B32, B42) for the engagement or coupling of fixing brackets (S) shown in Figures 4 and 5, respectively in a side sectional view and in a three- dimensional view.
  • Said fixing brackets (S) can be used to constrain a riser (A) to said base (B) to obtain a step.
  • Said fixing bracket (S) comprises a plane portion (SI) suited to be rested on the ground under said plane portion (Bl) 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 Figure 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).
  • said tab (S31) is bent in the shape of a C.
  • Said openings or seats (B32, B42) are preferably and conveniently created in said plane portion (Bl) 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.
  • 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).
  • 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).
  • the support comprises also at least one of said fixing brackets (S) as described above.
  • Figure 4 shows a sectional view of the lower bracket (S) only, while Figure 5 shows a three-dimensional view of the same lower bracket (S).
  • Figure 6 shows a sectional view of the upper bracket (P) only, while Figure 7 shows a three-dimensional view of the same upper bracket (P).
  • Figure 8 shows a possible embodiment of a head (T) of the new support.
  • Said head (T) has a substantially flat upper surface (Tl) on which the floor panels can be directly or indirectly rested.
