MOSAIC TESSERA PARTICULARLY FOR OUTDOOR AND/OR INDOOR PAVING

Abstract: A mosaic tessera, particularly for outdoor and/or indoor paving, constituted by a small metallic plate which is peripherally provided with perimetric raised portions forming a recess together with the corresponding face of the plate and by a filler element which is shaped complementarily to the recess and is associated with the recess so as to form a single tessera adapted to be applied to the foundation of the paving.

Description: MOSAIC TESSERA PARTICULARLY FOR OUTDOOR AND/OR INDOOR PAVING Technical field The present invention relates to a mosaic tessera particularly for outdoor and/or indoor paving. Background art Metal plates which, according to the most disparate criteria, are fixed on the foundation in order to provide a metallic paving are already known in the field of outdoor and/or indoor paving or cladding. Such metal plates have a limited thickness due to high cost of steel. Containment of the thickness of the large metal plate causes sagging, which becomes apparent with, the bending of the peripheral edges of large plates with respect to the plane that contains such plates. This forces the operator to intervene during and after laying in order to straighten and fix on the foundation the edges which are bent upwardly. Disclosure of the invention The aim of the present invention is to obviate the cited drawbacks by providing a paving or cladding which does not suffer the above mentioned problems. Within this aim, an object of the present invention is to provide mosaic tesserae whose shape is useful and has a low-cost for industrial application. Another object of the present invention is to provide a structure which is simple, relatively easy to provide in practice, safe in use and effective in operation. This aim and these and other objects which will become better apparent hereinafter are achieved by a mosaic tessera, particularly for outdoor and/or indoor paving, characterized in that it is constituted by a small metallic plate being peripherally provided with perimetric raised portions which form a recess together with the corresponding face and by a filler element which is shaped complementarily to said recess and is associated with said recess so as to form a single tessera adapted to be applied to the foundation of the paving. Brief Description of the Drawings Further characteristics and advantages will become better apparent from the following detailed description of a preferred but not exclusive embodiment of a mosaic tessera, according to the invention, illustrated only by way of non-limitative example in the accompanying drawings, wherein: Figure 1 is a perspective view of the tessera according to the invention, illustrating the filler element; Figure 2 is a sectional view, taken along a transverse axial plane, of the tessera. Ways of carrying out the invention With reference to the figures, the numeral 1 generally designates a mosaic tessera according to the invention. The tessera 1 is constituted by a small rectangular metallic plate 2 peripherally provided with perimetric raised portions 3 which form a recess 5 together with the corresponding face 4. Conveniently, the raised portions 3 give greater rigidity to the small metal plate 2. A filler element 6 is complementarily associated with the recess 5 and has an elasticity selected according to the application requirements, which can vary according to the type of material that composes the filler element 6; in particular, elasticity decreases from a high to a low value, when changing from rubber-like or gummy materials to electrically conducting pastes. The filler element has an internal surface 7 and an external surface 8 between which it is possible to interpose a film of adhesive 9 in order to facilitate the intimate bonding of the filler element 6 in the recess 5 and thus form, together with the small plate 2, the single tessera 1. The outer surface 8 forms peripherally perimetric rims 10 which produce a sort of sucker which is useful during the application step of the tessera 1 to the foundation of the floor. Conveniently, the filler element 6, made of rubber-like or gummy material or electrically conducting paste, acts, when the tessera is applied to the floor, as a dent-preventing pad in response to the external stresses induced by treading which affect each tessera 1 in practical use. In use, after composing the individual tessera 1 as described above, the tesserae are applied and glued to the foundation to as to form a metal floor. It has thus been shown that the invention achieves the intended aim and objects. In particular, it should be noted that each tessera can be obtained by blanking/punching a low-thickness steel lamina, thus having a considerable effect on the industrial cost-effectiveness of laying metal paving. In this manner it is possible to provide a metallic flooring in which the thickness of the plates is considerably lower than the thickness of large metal plates. Finally, it is noted that the tesserae thus obtained are extremely light in weight and easy to transport and store. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. In particular, tesserae having geometric shapes other than the one illustrated also fall within the scope of the present invention. The details may further be replaced with other technically equivalent ones. Finally, the dimensions may be any according to requirements without thereby abandoning the scope of the protection of the appended claims.

Claims: CLAIMS: 1. A mosaic tessera, for outdoor and/or indoor paving, characterized in that it comprises a small metallic plate, which is peripherally provided with perimetric raised portions forming a recess together with an internal corresponding face of the plate; and a filler element, shaped complementarily to said recess, and accommodated at said recess so as to form a single tessera adapted to be applied to a foundation of the paving. 2. The tessera of claim 1, characterized in that said filler element is substantially elastic. 3. The tessera according to claims 1 and 2, characterized in that said filler element is made of any of a rubber-like and gummy material. 4. The tessera according to claims 1 and 2, characterized in that said filler element is constituted by a substantially electrically conducting paste. 5. The tessera according to any of the preceding claims, characterized in that it comprises a film of adhesive arranged between a surface region of said filler element and said internal plate face, to facilitate intimate bonding of said filler element in said recess. 6. The tessera according to any of the preceding claims, characterized in that said filler element has an outer surface which has, along a peripheral area thereof, perimetral rims which form a sucker element facilitating application of said tessera to said foundation. 7. The tessera according to any of the preceding claims, characterized in that said filler element acts as a pad for preventing dents in response to external treading stresses.
