Description

RAISED, SUPPORTING FACING STRUCTURE FOR COVERING FLOORS, WALLS AND THE LIKE
TECHNICAL FIELD The present invention relates to a raised, supporting facing structure for covering floors, walls and the like.
More in detail, the present invention relates to a raised treadable floor of the backlit type, to which the following description will explicitly refer without however loosing in generality. BACKGROUND ART
As known, raised treadable floors generally consist of a series of supporting pedestals distributed on the surface of the raw floor to be faced according to a row or column configuration, and of a series of structural panels arranged in horizontal position resting on the various supporting pedestals side by side, so as to form a horizontal treadable surface which extends parallelly and seamlessly with respect to the floor to be faced, at a predetermined distance from the latter, so as to form a service gap with the aforesaid floor generally destined to accommodate the electrical cables of the electrical system of the building, the pipes of the air conditioning system of the building, the wirings of the data transmission network of the building, etc.
In recent years, treadable floors in which some of the structural panels are formed by transparent or semitransparent material so as to allow the passage of the light produced by a series of neon lamps or the like positioned underneath the panels themselves, inside the service gap, have appeared on the market.
In the intention of the manufacturers, the positioning of some light sources underneath the transparent or semitransparent plastic material structural panels should have allowed to create particularly appealing plays of light, capable of making the environments brighter, warmer and more welcoming.
Unfortunately, the treadable floors of the backlit type did not become very successful among architects and interior designers because the light which is output by the transparent or semitransparent material panels does not have a uniform distribution, and thus it is not aesthetically pleasant.
DISCLOSURE OF INVENTION
It is therefore the object of the present invention to make a raised treadable floor of the backlit type which is free from the above-described drawbacks .
According to the present invention, it is therefore made a raised, supporting facing structure for covering floors, walls and the like as explained in claim 1 and preferably, but not necessarily, in any of the subsequent claims, either directly or indirectly dependent from claim 1. BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be described with reference to the accompanying drawings which illustrate a non-limitative example of embodiment thereof, in which: - figure 1 is a perspective view of a raised treadable floor made according to the dictates of the present invention, with parts removed for clarity;
- figure 2 is a plan view of the raised treadable floor shown in figure 1, on an enlarged scale, with parts in section and parts removed for clarity;
- figure 3 is a side view of the treadable floor shown in figure 2, taken along the section line III-III; while
- figures 4 and 5 are two sectional views of a facing wall and a partition wall made according to the dictates of the present invention, respectively. BEST MODE FOR CARRYING OUT THE INVENTION With reference to figures 1 and 2, numeral 1 indicates as a whole a raised, supporting facing structure, specifically adapted to be able to face a raw masonry floor P or the like, forming with the latter a service gap generally intended to accommodate the electrical cables of the electrical system of the building, the pipes of the conditioning system of the building, the wirings of the data transmission system of the building, etc.
Obviously, the facing structure 1 may also be used to face the front of any other type of flat structural element, such as for example the wall or the ceiling of any room of a building.
Facing structure 1, commonly also called "raised treadable floor", essentially comprises a series of supporting spacer pedestals 2 appropriately distributed on the surface of floor P to be faced, and a series of structural panels 3 arranged in essentially horizontal position resting on supporting pedestals 2 with the side edges side by side, so as to form a horizontal treadable covering surface C which extends parallelly and seamlessly with respect to floor P to be faced, at a predetermined distance from the latter, so as to form with floor P the aforementioned service gap. More in detail, with specific reference to figure 1, pedestals 2 are distributed on the surface of floor P to be faced preferably, but not necessarily, according to a row-and-column configuration, while panels 3 are formed by transparent or semitransparent material, have a preferably, but not necessarily, rectangular or square shape, and are finally arranged with their vertexes each resting on a corresponding pedestal 2 of the structure shared with the immediately adjacent structural panels 3.
Both pedestals 2 and panels 3 are obviously structured and dimensioned so as to be able to satisfy the type-approval standards contemplated for raised treadable floors. In other words, both pedestals 2 and panels 3 are structured and dimensioned so as to be able to support the weight of a plurality of people which move and/or stand over the structure of facing 1.
With reference to figures 1 and 3, specifically, each pedestal 2 is formed by metallic material, and essentially comprises a plate or base 4 resting on the ground which is adapted to be anchored to floor P to be faced preferably, but not necessarily, by means of adhesives and/or anchor bolts of known type; a structural rod 5 which extends in cantilever fashion from plate 4 resting on the ground towards panels 3 above maintaining itself coaxial to an axis A essentially perpendicular to the laying plane of plate 4 itself; and finally a panel holder head 6 which is rigidly fastened onto the terminal end of structural rod 5 and is provided with an upper flat face 6a which extends perpendicularly to axis A longitudinal to rod 5, from the part opposite to plate 4, and is adapted to be in contact with the rear face of panels 3 which form covering surface C. In the example shown, specifically, structural rod 5 is formed by a cylindrical tubular sleeve 7 which extends in cantilever fashion from plate 4, by a rod or cylindrical pin 8 partially screwed within tubular sleeve 7, and finally by fastening bolt 9 which is adjustably screwed onto an intermediate segment of cylindrical rod 8 so as to be able to be abuttingly positioned on the end of tubular sleeve 7 rigidly locking the two parts together .
Regarding structural panels 3, instead, in the example shown each panel consists of a preferably but not necessarily, white or opaline semitransparent laminated glass sheet 3.
More in detail, in the example shown, each panel 3 is formed by a laminated glass sheet 3 consisting of three tempered glass sheets 10a, 10b and 10c separated by two adhesive films 11 formed by polyvinyl butyral (commonly called PVB) , or similar transparent or semitransparent plastic material, such as polyurethane. Glass sheet 10a which forms the "visible" surface of covering surface C is formed by crystalline or extra- clear glass, while at least one of the other two glass sheets 10b and 10c is formed by semitransparent opaline white glass .
Instead of or as an alternative to the use of a glass panel 10b, 10c formed by semitransparent opaline white glass, at least one of the two adhesive films 11 of laminated glass sheet 3 may be made of opaline white semitransparent plastic material.
In addition to the above, adhesive film 11 which separates glass sheet 10b from glass sheet 10a or 10c may possibly by provided with writings and/or decorations made for example by silk-screen printing.
According to a different embodiment, laminated glass sheet 3 may also be formed by a laminated glass sheet of the "crashed" type, i.e. a laminated glass sheet 3 in which a central glass sheet 10b consists of a uniformly crushed tempered glass sheet, while the two side glass sheets 10a and 10c are traditional tempered glass sheets .
Obviously, structural panels 3 may also consist of transparent or semitransparent composite material of proper thickness .
With reference to figures 1, 2 and 3, unlike the currently known "raised treadable floors", facing structure 1 is also provided with a series of distributed light emission, planar development backlighting lamps 12, each of which is fixed onto pedestals 2 underneath a corresponding semitransparent material panel 3 structured so as to project an essentially uniform light beam towards panel 3 above.
Each backlighting lamp 12 essentially comprises a flat sheet 13 of transparent or semitransparent material which is positioned underneath corresponding panel 3, parallel and facing the same, and has a shape essentially equal to that of panel 3 itself, and a series of supporting brackets 14 which are fixed to the various pedestals 2 which support panel 3, and are adapted to support flat sheet 13 at the vertexes of the same, maintaining flat sheet 13 itself at a predetermined distance d from the internal face of panel 3, so as to form a light reverberation chamber with panel 3. Each backlighting lamp 12 is further provided with a series of light emitting diodes 15, traditionally called λVLEDs", or similar punctiform light sources, which are positioned on the various supporting brackets 14 so that each is arranged facing and essentially abutting on the side flank of flat sheet 13 so as to be able to project the produced light directly inside the body of flat sheet 13 through the same side flank. Light which would remain trapped within the body of flat sheet 13 by effect of the same physical principles which govern the propagation of light within optical fibre cables, if flat sheet 13 were not specifically structured so as to cause the progressive output of the light through the surface of front face 13a, i.e. the face facing towards panel 3, so as to be able to backlight panel 3 itself. More in detail, light emitting diodes 15 are positioned on the various supporting brackets 14 so as to be arranged facing and essentially abuttingly on the side flank of flat sheet 13, at the vertexes of the sheet itself, so as to be able to project the light produced directly within the body of flat sheet 13 through the vertexes of flat sheet 13.
Specifically, with reference to figure 2, in the example shown, flat sheet 13 presents an essentially rectangular or square shape, and has four bevelled vertexes so that each of them ends with a rectilinear segment perpendicular to the bisectors of the vertex itself, while light emitting diodes 15 are grouped on each supporting bracket 14 so as to be facing and essentially abutting on the rectilinear bevelling obtained at the vertex of flat sheet 13 , so as to be able to project the produced light directly within the body of flat sheet 13 through the bevelling itself.
With reference to figures 2 and 3, in the example shown, each supporting brackets 14 is instead capable of simultaneously supporting the vertexes of the four flat sheets 13 which surround structural rod 5 to which the bracket is fixed, and diodes 15 of each supporting bracket 14 are grouped in four groups of diodes 15, each of which is adapted to be arranged facing and essentially abutting on the bevelled vertex of a corresponding flat sheet 13.
Specifically, in the example shown, flat sheet 13 is formed by polymethyl methacrylate (commonly called Plexiglas or PMMA) or similar plastic material (such as for example polyester) , and is provided with a series of preferably, but not necessarily, lenticular profile blank recesses or holes, of diameter smaller than one millimetre, which are appropriately distributed on the entire surface of rear face 13b of the sheet, i.e. on the face facing towards floor P to be faced, so as to deviate the light trapped inside the sheet itself towards front face 13a of flat sheet 13 itself.
The progressive output of the light through front face 13a of flat sheet 13 may also be obtained by subjecting the surface of the aforesaid face and/or the opposite surface by a surface abrasion process (sandblasting) , satin-etching or silk-screen printing so as to locally increase the surface roughness of flat sheet 13.
Obviously, the preferably, but not necessarily, lenticular profile blank recesses or holes may be distributed only on some portions of the surface of rear face 13b of the sheet, so as to deviate the light trapped inside glass sheet 13 towards predetermined zones of front face 13a of flat sheet 13 itself so as to backlight writings, drawings or similar decorations.
Furthermore, in the example shown, flat sheet 13 presents, along the rectilinear bevelling of each of fourth vertexes of the plate, a series of niches or cavities each of which is adapted to accommodate a corresponding diode 15 of supporting brackets 14.
In order to maximise the flow of light output from front face 13a of flat sheet 13, the backlighting lamp 12 is further preferably, but not necessarily, also provided with an opaque covering sheet 16, possibly also of reflecting type, which completely covers the surface of rear face 13b of flat sheet 13 so as to be able to reflect/diffuse the light which tends to accidentally come out from rear face 13b again towards the inside of flat sheet 13 and, consequently, towards front face 13a of the sheet itself.
Specifically, in the example shown, covering sheet 16 consists of a bottom wall of an opaque white colour sheet holder tray 16, which is dimensioned so as to be able to accommodate flat sheet 13 with the exception of front face 13a and bevelled vertexes of flat sheet 13, where it is free from the side boards so as to leave the flank of the sheet uncovered.
As regards instead supporting brackets 14 , with reference to figures 1, 2 and 3, in the example shown each supporting bracket 14 is essentially formed by a metallic material plate 17 which lays on a plane perpendicular to axis A of .structural rod 5, and is fixed in adjustable position on structural rod 5 of pedestal 2 so as to be able to restingly receive the vertexes of the four flat sheets 13 which surround supporting rod 5.
More in detail, plate 17 is fixed in adjustable position on cylindrical rod 8 of pedestal 2 by means of a fastening bolt 18 screwed onto structural rod 5, and is centrally provided with a series of protruding fins 17a which protrudingly extend from the upper face of plate 17 towards panel holder head 6 above maintaining itself parallel to the bevelled edge of flat sheet 13, and which perform the double function of supporting light emitting diodes 15 and of disposing by convection the heat produced by diodes 15 themselves.
In the example shown, indeed, light emitting diodes 15 face a same bevelled vertex of flat sheet 13, are mounted on a same supporting base which is fastened by means of bolts onto a flank of one of the protruding fins 17a of plate 17, so as to transmit by conduction the produced heat within plate 17, and are fed by an electronic control unit (not shown) of the known type which may possibly be also able to regulate the intensity and the colour of the light produced by the single diodes 15 of the terminal board. With reference to figures 1 and 3, in the example shown, each of supporting brackets 14 is further preferably, but not necessarily, provided with a locking and protective cap or lid 19 which is fixed onto plate 17, over the bevelled vertexes of flat sheets 13 resting on plate 17, so as to withhold flat sheets 13 in position concurrently covering the bevelled vertexes of the sheets themselves and diode 15 facing them, so as to prevent the light generated by diodes 15 from reaching panels 3 without firstly crossing flat sheet 13. The operation of facing structure 1 or rather of "raised treadable floor" 1 is easily inferrable from that described and illustrated above.
The light produced by diodes 15 positioned on supporting brackets 14 penetrates within the body of flat sheet 13 through the four vertexes of the same sheet and is then output in progressive and distributed manner from the surface of front face 13a of the sheet so as to be able to backlight panel 3 , while the reverberation chamber between panel 3 and flat sheet 13 further homogenise the distribution of the intensity of the light on the entire surface of the "visible" face of panel 3. The advantages of the facing structure 1 described and shown above are apparent: in virtue of the specific constructive solutions adopted for backlighting lamps 12, the "visible" face of panel 3 is backlit up to the edge with a light of uniform intensity, entirely eliminating the typical drawbacks of the currently known "raised treadable floors" .
Finally, in addition to that described above, the manufacturing costs of facing structure 1 is only slightly higher than those of the currently known "raised treadable floors", with all the advantages that this implies .
It is finally apparent that changes and variants can be made to facing structure 1 described and shown above without departing from the scope of protection of the present invention.
For example, with reference to figure 4, facing structure 1 may be used for facing a vertical wall V by adopting supporting pedestals 2 in which the vertexes of panels 3 are abuttingly maintained on upper flat face 6a of panel holder head 6 by means of a flat-head locking screw 6b, which is fastened onto the panel holder head 6 so that the threaded shank of the screw extends coaxially to axis A of pedestal 2, and so that the flat head of the screw is arranged parallel and facing flat sheet βa of panel holder head 6 , over panels 3.
Obviously, in this case, covering surface C formed by panels 3 arranged side by side extends parallelly to the surface of vertical wall V, at a predetermined distance from the latter.
With reference to figure 5, instead, facing structure 1 may instead be used to make a partition wall for interiors by adopting supporting pedestals 2 in which plate or base 4 resting on the ground is replaced by a terminal 4' structured so as to be able to rigidly fix the entire pedestal 2 onto a rigid structural frame T of metallic tubes or the like, rigidly anchored in turn to the ceiling and to the floor of the room to be partitioned.
Obviously, also in this case, the vertexes of panels 3 are maintained abutting on the upper flat faces βa of panel holder heads 6 by means of the flat-head locking screws βb, each of which is screwed onto the panel holder head 6 so that the threaded shank of the screw extends axially to axis A of pedestal 2, and so that the flat head of the screw is arranged parallelly and facing flat face 6a of panel holder head 6, over panels 3.
Obviously, covering surface C formed by the various panels 3 arranged side by side, is parallel to the laying surface of structural frame T, at a predetermined distance from the latter.
