Definitions

  • the present invention relates to a walk-on back-lit tile for tiling floors and walls in general.
  • the back-lit tiles currently known are so thick and have such high production costs that they are, in effect, not marketable.
  • the object of the present invention is therefore to construct a walk-on back-lit tile for tiling floors and walls in general that is free from the above described drawbacks.
  • a walk-on back-lit tile for tiling floors and walls in general has been constructed as defined in claim 1 and possibly in any of the subsequent claims, directly or indirectly depending from claim 1.
  • FIG. 1 is an exploded perspective view of a walk- on back-lit tile for tiling floors and walls in general constructed according to the teachings of the present invention, with parts removed for reasons of clarity;
  • figure 2 is a sectional side view of the walk-on back-lit tile illustrated in figure 1 with parts removed for clarity;
  • FIG. 3 and 4 are two sectional views of as many variants of the walk-on back-lit tile illustrated in figures 1 and 2.
  • the walk-on back-lit tile 1 essentially comprises an external pan or box-type container 2 of a preferably, but not necessarily, parallelepiped shape; a first flat slab 3 in transparent and/or sei ⁇ itransparent material that has a complementary shape to that of the opening of the box- type container 2, i.e.
  • a second flat slab 4 in transparent or semitransparent material that has a shape substantially equal to that of the flat slab 3, i.e. has a substantially rectangular or square shape, and is positioned inside the box-type container 2 so as to be parallel and facing the flat slab 3.
  • the walk-on back-lit tile 1 also comprises a spacer frame 5 that is substantially similar in shape to the peripheral edge of the flat slab 4, i.e. has a rectangular or square shape, and is sized so as to be fitted inside the box-type container 2 covering the front face 4a of the flat slab 4, or better the peripheral edge of the same, so as to be interposed between the flat slab 3 and the flat slab 4 so as to hold the rear face 3b of the flat slab 3 parallel and facing the front face 4a of the flat slab 4, at a preset distance di from the same. That distance is obviously equal to the thickness of the spacer frame 5.
  • the spacer frame 5 is shaped so as that the central passing aperture has a diverging profile, i.e.
  • the spacer frame 5 is shaped such that its four internal sides, hereinafter indicated by the numeral 5a, are defined by as many flat surfaces inclined of an angle ⁇ with a value between 40° and 80°, and preferably, but not necessarily, equal to 50°, with respect to the flat surface of the front face 4a of the flat slab 4.
  • the spacer frame 5 is formed of four straight longitudinal members 6, with a cross-section of a substantially rectangular trapezoidal shape, which are joined to each other at their heads so as to be arranged in parallel pairs and reciprocally facing, so as to form the four sides of a rectangle. More precisely, in the example illustrated each of the longitudinal members 6 has a cross-section of a rectangular trapezoid shape in which the oblique side is inclined 50° with respect to the two bases of the trapezoid and, therefore, to the surface of the immediately adjacent flat sheets 3 and 4. Obviously, the internal sides 5a of the spacer frame 5 need not necessarily all have the same angle ⁇ of inclination with respect to the flat surface 4a of the flat slab 4.
  • the walk-on back-lit tile 1 also comprises one or more longitudinal development light sources 7, each of which is positioned inside the box-type container 2 under the spacer frame 5, facing and substantially in abutment with a respective side edge of the flat slab 4, and extends preferably, but not necessarily, for the entire length of the side edge itself of the flat slab 4 so as to be able to project the light produced directly inside the body of the flat slab 4 through the whole above-mentioned side edge.
  • the flat slab 4 is made preferably, but not necessarily, in polymethyl methacrylate (commonly known as Plexiglas or PMMA) or similar plastic material (such as polyester for example) , and is provided with a series of blind holes of very small diameter that are distributed in a suitable manner over the entire surface of the front face 4a so as to direct the light trapped inside the flat slab 4 outwards.
  • polymethyl methacrylate commonly known as Plexiglas or PMMA
  • similar plastic material such as polyester for example
  • the progressive outflow of the light through the front face 4a of the flat slab 4 can also be obtained by subjecting the surface of the above-mentioned face to a process of superficial abrasion (sanding), satinizing or screen printing so as to locally increase the roughness of the surface of the flat slab 4.
  • the walk-on back- lit tile 1 is provided with two light sources 7 which are abutly arranged with two opposing side edges of the flat slab 4, and each of these light sources 7 is essentially composed of a row of light emitting diodes 8, traditionally called “led”, suitably fixed on a supporting flat strip 9, and of an electronic control unit (not shown) of a known type which is adapted to power on command the above-mentioned diodes 8, possibly adjusting the colour and intensity features of the light produced.
  • the flat strip 9 supporting the row of diodes 8 is inserted between the side edge of the flat slab 4 and the wall of the box-type container 2, under the corresponding longitudinal member 6 of the spacer frame 5, with the row of diodes 8 facing the side edge of the flat slab 4, while the electronic control unit is housed inside one of the other longitudinal members 6 of the spacer frame 5, as will be better explained below.
  • the walk-on back- lit tile 1 is preferably, but not necessarily, also provided with a coating film or opaque sheet 10, possibly also of a reflecting type, which is positioned on the bottom of the box-type container 2 directly facing the rear face 4b of the flat slab 4, so as to be able to reflect/spread back towards the flat slab 4 and, consequently, towards the flat slab 3, the light that accidentally leaks from the rear face 4b of the flat slab 4.
  • the film or opaque sheet 10 extends over the bottom of the box-type container 2 covering substantially the entire surface of the rear face 4b of the flat slab 4.
  • the film or opaque sheet 10 consists of a suitable layer 10 of opaque paint of a colour preferably, but not necessarily, white opaline which completely covers the internal surface of the box-type container 2 directly facing the rear face 4b of the flat slab 4.
  • the walk- on back-lit tile 1 is preferably, but not necessarily, provided with a rear spacer frame which is adapted to be inserted into the box-type container 2, between the flat slab 4 and the bottom of the box-type container 2, so as to maintain the rear face 4b of the flat slab 4 at a preset distance d 2 from the film or opaque sheet 10, so as to form with the latter a second closed reverberation chamber.
  • the rear spacer frame is adapted to maintain the rear face 4b of the flat slab 4 at a distance d2 of about 2-3 millimetres from the coating film or opaque sheet 10, and is composed of a spacer disc 12 interposed between the flat slab 4 and the bottom of the box-type container 2, at the centre of the flat slab 4 itself, and of the four longitudinal members 6 which already form the spacer frame 6.
  • each of them has a tubular section and is provided with a longitudinal slit or passing notch having a width which approximates by excess the thickness of the flat slab 4, and extending continuously along the entire wall of the longitudinal member 6 corresponding to the oblique side of the rectangular trapezoid so as to allow the insertion of the side edge of the flat slab 4 into the longitudinal member 6 together with a possible longitudinal development light sources 7.
  • the longitudinal slit or passing notch is formed in the wall of the longitudinal member 6 so as to maintain the rear face 4b of the flat slab 4 at the distance d 2 from the film or opaque sheet 10, i.e. from the bottom of the box-type container 2.
  • the longitudinal members 6 that form the spacer frame 5 are the C-shaped profiled straight bars having a cross-section of a substantially rectangular trapezoidal shape, in which the oblique side is inclined at 50° with respect to the two bases of the trapezoid and forms a longitudinal channel adapted to receive the side edge of the flat slab 4 inside the longitudinal member 6 together with a possible longitudinal development light sources 7.
  • the spacer frame 5 can be completely separated from the rear spacer frame.
  • the longitudinal members 6 are sized so as to rest on the front face 4a of the flat slab 4 and the rear spacer frame is composed of the spacer disc 12 and of four straight strips 13 of elongated rectangular section which are reciprocally coupled at the head so as to form a peripheral frame substantially equal to the shape of the peripheral edge of the transparent flat slab 4, i.e. has a rectangular or square shape, and is sized so as to be inserted into the box-type container 2 between the flat slab 4 and the bottom of the box-type container 2.
  • the four straight strips 13 of an elongated rectangular section form a peripheral frame whose height is equal to the nominal distance d2 which separates the rear face 4b of the flat slab 4 from the film or opaque sheet 10, i.e. from the bottom of the box- type container 2.
  • the spacer disc 12 in both cases it has a thickness greater than the nominal distance d ⁇ which separates the rear face 4b of the flat slab 4 from the film or opaque sheet 10 so as to create a slight crowning in the flat slab 4 which facilitates the uniform distribution of the light.
  • the flat slab 3 in the example shown consists of three sheets of tempered glass 14a, 14b and 14c separated by two adhesive films 15 in polyvinyl butyral (commonly known as PVB) or similar transparent or semi-transparent plastic material, such as polyurethane, all rigidly fixed to the box-type container 2 and to the spacer frame 5 preferably, but not necessarily, by means of an peripheral layer 16 of adhesive and with the possible interposition of a peripheral seal (not shown) .
  • the glass sheet 14a turned towards the outside of the box-type container 2 is made of crystalline or extra-clear transparent glass, while at least one of the remaining glass sheets 14b and 14c is made of semitransparent white opaline glass.
  • the glass sheet 14c directly facing the flat slab 4 is made of semitransparent white opaline glass
  • the intermediate glass sheet 14b can be made either of crystalline transparent glass or in semitransparent white opaline glass.
  • at least one of the two adhesive films 15 is made of semitransparent white opaline plastic material.
  • the adhesive film 15 that separates the glass sheet 14a from the glass sheet 14b can carry words and/or decorations made for example by screen printing.
  • the functioning of the walk-on back-lit tile 1 is easily inferred from the above description and the illustrations.
  • the light produced by the longitudinal development light source (s) 7 positioned at the side edges of the flat slab 4 penetrates the body of the flat slab 4 through the side edges and then flows out progressively being distributed by the surface of the front face 4a so as to be able to back light the flat slab 3, while the reverberation chamber between the flat slab 3 and the flat slab 4 and the optional reverberation chamber between the flat slab 4 and the coating film or opaque sheet 10 make it possible to uniformly distribute the light over the entire surface of the "visible" face of the tile.
  • the walk-on back-lit tile 1 has considerably lower production costs than the back-lit tiles currently known.
  • the longitudinal development light source (s) 7 are formed of traditional fluorescent gas discharge lamps 17 with straight fluorescent tubes, commonly known as ⁇ neon tubes' , each of which is positioned inside a corresponding longitudinal member 6 with its straight fluorescent tube abutting with the side edge of the flat slab 4.
