Description

[Technical Field]

[0001] The present invention belongs to the technical field of laminar elements.

[0002] More specifically, the present invention relates to a laminar element having an upper surface visible during use, a lower surface parallel to and opposite said upper surface, and a lateral periphery, said laminar element being composed of a plurality of sheets.

[0003] The present invention also relates to products made from said layer elements, in particular tops or countertops, preferably kitchen countertops, and steps. [Background technology]

[0004] Layered elements, also known as laminates, comprise a series of unidirectional sheets laminated and bonded together. The properties of the layered element depend, inter alia, on the number of sheets and the material and properties of the individual sheets. These properties allow for high performance layered elements suitable for applications that must withstand extreme temperature, humidity, abrasion, bending, and / or pressure conditions, for example.

[0005] One example of an application requiring high performance layered elements is the manufacture of kitchen countertops, particularly those that make up induction cooktops. Such countertops are subject to constant moisture, particularly in and around the hob area, but also in other areas where rapid temperature changes occur, such as around the sink.

[0006] Another example where high-performance layered elements are used is the manufacture of steps or staircases, where it is particularly important not only to have a core with high structural strength and a surface with anti-slip properties, but also, in the case of outdoor staircases for example, to be able to withstand sudden changes in temperature and humidity without changing their qualities or properties.

[0007] In this regard, there are risks associated with the use of products containing these layered elements.

[0008] Returning to the example of the layered elements included in a kitchen countertop with an induction cooktop, such countertops are typically subject to rapid temperature changes, particularly in the heating area. Furthermore, certain areas, such as in and around the heating area, not only reach high temperatures during use, but also retain residual heat for some time after use. This poses a clear risk of burns to users, especially considering that in this type of product, which strives to combine functionality and aesthetics, dangerous hot spots are often not immediately visible.

[0009] When these layered elements are used for steps, it is necessary that they remain visible in low or no light conditions, particularly if they are part of a staircase located on a path used in an emergency, or simply to facilitate use and minimize the risk of tripping or falling for the user.

[0010] In many cases, the need to maintain the properties of the layered elements that give the final product its high performance makes it impossible or difficult to implement safety systems in these layered elements that mitigate the aforementioned risks and at the same time do not adversely affect the performance of the layered elements themselves, nor their aesthetic appearance, which is often an important factor to consider.

[0011] Returning to the kitchen countertop example, the regulations only require that kitchen cooktops, glass-ceramic cooktops, or induction cooktops, or countertops containing them, be equipped with associated indicators in a control area located on the top surface of the cooktop / countertop to inform the user of both the on / off status of the appliance and the presence or absence of residual heat on the cooktop / countertop surface. These indicators are typically small in size so as to have minimal impact on the aesthetics of the product. Furthermore, because these indicators are located on the top surface, they may be accidentally covered by, for example, cooking vessels, utensils, cloths, food waste, or dirt, making them invisible to the user—a common occurrence since products incorporating such layered elements are often used as work surfaces. Furthermore, indicators located on the top surface are often invisible to particularly vulnerable users, such as children, whose height may prevent them from seeing the safety indicators, thereby increasing the risk of accidents.

[0012] For steps, fluorescent lamps or external lighting devices placed next to or below the steps are commonly used to ensure visibility in low-light or no-light conditions. These safety elements, in particular, have the disadvantage of requiring staircase design conditions, such as cantilevered stairs, where lighting can be placed at the bottom near the leading edge. Furthermore, because they are external elements, there is a risk that these elements may become dislodged or damaged, rendering them inoperable.

[0013] In addition to the problems mentioned above, the safety element must be able to withstand and function under the particularly harsh conditions to which layered elements of this type are usually exposed.

[0014] In view of the above, there is a clear need for high performance layer elements that improve the safety of the products in which they are included, while at the same time not compromising the technical properties of the products of which they are a part. DISCLOSURE OF THE INVENTION

[0015] The object of the present invention is to provide a layered element of the type indicated at the beginning, which is able to improve the safety of the product into which it is incorporated, while at the same time maintaining the technical properties of said product.

[0016] This object is achieved by a layer element of the type indicated at the beginning, comprising a first upper sheet, the upper surface of which forms the upper surface of the layer element, and a second sheet comprising at least one lateral segment of light-transmitting material, said lateral segment of light-transmitting material having at least one light-input surface and at least one light-output surface, the layer element further comprising a light-emitting device arranged next to said at least one light-input surface such that light emitted by said light-emitting device enters said lateral segment of light-transmitting material through said at least one light-input surface and exits said lateral segment of light-transmitting material through said at least one light-output surface, and characterized in that there is an intermediate third sheet of aluminum between said first upper sheet and said at least one lateral segment of light-transmitting material.

[0017] By incorporating at least one side segment of light-transmitting material having a light-input surface and at least one light-exiting surface and a light-emitting device disposed adjacent to the at least one light-input surface, such that light emitted by the light-emitting device enters the side segment of light-transmitting material through the at least one light-input surface and exits the side segment of light-transmitting material through the at least one light-exiting surface, the layered element can emit light throughout its lateral periphery when in use. In addition to being more visible from a distance than known light indicators, the ambient light of the layered element according to the present invention has a number of additional advantages. Meanwhile, in most products in which layered elements are used, particularly countertops and countertops, the ambient light segment is located in a position visible from the front and at a privileged height so that it can be seen by users, especially children, who are the most prone to accidents. Furthermore, due to its location, the ambient light of the layered element cannot be accidentally obscured by objects placed on its upper surface, thereby preventing users from seeing it and minimizing the risk of accidents. Furthermore, the layered elements according to the invention make it possible to provide illumination for elements that are often combined with such layered elements and for which there are no safe solutions that comply with regulations or which are simply long-lasting and aesthetically pleasing at the same time. For example, the area around a kitchen sink is a place where the use of electrical components is very limited due to the constant presence of water. Another example is drawers and cabinets that are often located under countertops, which can also be illuminated with the layered elements according to the invention. Finally, other exemplary applications in which the layered elements according to the invention are particularly advantageous include steps, or generally the treads of staircases, which, in addition to being prone to soiling, have particularly high visibility in peripheral positions, especially in front from the point of view of the user ascending the stairs, which is relevant for preventing accidents due to slips, trips and falls.

[0050] In the context of the present invention, the expression "functionally associated" means that the functionally associated elements have an associated function, i.e., a relationship exists between their operations. This functional association may be mediated by a direct connection between the functionally associated elements, such that one performs the function of the other and / or vice versa, and / or by one or more elements that act as a connection and / or controller between them and that further process information coming from each of the functionally associated elements, and that may be programmable.

[0052] In a preferred embodiment of the invention, the light emitting device comprises a plurality of LEDs, said LEDs having an opening angle greater than 90°, preferably greater than 170°.

[0053] Light-emitting diodes, or LEDs, are particularly advantageous because they are easy to install, versatile, operate at low voltages, and consume little power. The opening angle of the LED determines the direction in which the LED can emit light. Opening angles greater than 90°, especially angles of 170°, are advantageous because they allow greater flexibility in arranging these LEDs next to the incident surface while always allowing light emitted by the light-emitting device to impinge on at least one side segment of the second sheet of light-transmitting material.

[0054] Preferably the LED is a DC LED with a voltage of 12 or 24 volts, preferably 24 volts.

[0058] In the context of the present invention, a "ceramic material" is a solid, hot-formed inorganic material. Ceramic materials are typically formed into specific shapes, such as sheets or plates, by processes such as pressing or extrusion at room temperature, followed by drying and firing at a high enough temperature to develop the desired properties. In terms of composition, "ceramic materials" primarily consist of aluminum silicate-based mixtures, although there are also specialized ceramic materials based on other oxides, such as aluminum oxide or alumina. Furthermore, ceramic materials may comprise other inorganic components, such as feldspar, carbonates, quartz, other silicates, kaolin, zirconium oxide, zinc oxide, etc., depending on the origin of the raw materials used in their production and the properties to be achieved in the final material.

[0059] A distinction can be made among ceramic materials based on their molecular structure: materials with a crystalline structure and materials with a non-crystalline or amorphous structure, also known as glasses.

[0060] In the context of this invention, "glass" refers to a non-crystalline or amorphous ceramic material in which atoms are arranged in a disordered and random manner. The most common glasses are silicate-based, but other compositions are possible. The final composition can vary depending on the desired properties of the final material. The amorphous properties are achieved by specific manufacturing methods depending on the application, which often involve heating at very high temperatures.

[0061] In the context of the present invention, a "porcelain material" refers to a ceramic material whose manufacturing method improves its mechanical properties and heat resistance compared to other ceramic materials. Examples of "porcelain materials" are fully vitrified ceramic materials, such as those belonging to the AIa or BIa group according to standard ISO 13006:2018 (and its equivalent EN 14411:2016), which are formed by extrusion (AIa) or pressing (BIa). Porcelain materials are characterized, inter alia, by having a water absorption coefficient (Ev) that is considered very low, preferably 0.5% by weight or less.

[0062] In the context of the present invention, a "glass-ceramic material" is a polycrystalline material obtained by a controlled denitrification process of glass having a composition appropriate for its desired application. These glass-ceramic materials combine the special properties of conventional ceramics with the characteristic properties of glass in a single material and are considered sophisticated ceramic materials due to the particularly attractive properties of the final product, such as high hardness, minimal porosity, and high elastic modulus. Examples of glass-ceramic materials include, in particular, those specified in standards EN 1748-2-1:2006 and EN 1748-2-2:2005, which are used, for example, in the manufacture of glass-ceramic cooktops.

[0063] In the context of the present invention, "particleboard" refers to a board made of wood chips or particles mixed with a thermosetting adhesive and / or resin, which is then subjected to a hot press to form the board. Depending on the final properties obtained in the final product, several types of wood and adhesives / resins, as well as different manufacturing conditions, can be used. Examples of particleboards are those described in standards EN 309:2006 (Particleboard - Definition and Classification) and EN 312:2010 (Particleboard - Specifications), which are used, for example, in the manufacture of kitchen countertops.

[0064] In the context of the present invention, "MDF boards" (medium density fiberboards), also known as "dry process fiberboards", are boards in which wood fibers are mixed with thermosetting adhesives and / or resins and pressed at high pressure and temperature. Examples of these MDF boards are those described in standard EN 622-5:2010 (Fiberboards. Specifications. Part 5: Requirements for dry process Fiberboards (MDF)).

[0065] In the context of the present invention, a "high-pressure laminate board" or "HPL board" is a board made of several cellulose layers or sheets impregnated with phenolic resin, which is subjected to high pressure and temperature during its manufacture. Examples of HPL boards are those described in standards EN 438-1:2016 and EN 438-4:2005.

[0066] In the context of the present invention, a "solid surface material" is a synthetic material consisting of a combination of minerals and resins, preferably alumina trihydrate (ATH), acrylic, epoxy or polyester resins, and pigments. The advantage of using a solid surface material is that the layer element according to the present invention can be formed into a desired shape. For example, a portion of the layer element at each of its ends can be heated and bent transversely relative to the upper and lower surfaces of the layer element, forming a C-shape, with the bent ends serving as support legs for the layer element.

[0067] Preferably, the first sheet has a thickness between 2 mm and 20 mm, preferably between 3 mm and 12 mm.

[0068] Preferably, the intermediate third sheet of aluminium has a thickness between 0.1 mm and 4 mm, more preferably between 0.2 mm and 1 mm, even more preferably between 0.25 mm and 0.5 mm.

[0073] In another preferred embodiment of the invention, and if there is a fourth sheet, the layer element comprises a fifth sheet located below said fourth sheet, the fifth sheet being made of a material selected from the group consisting of ceramic materials, glass, porcelain materials, glass-ceramic materials, lacquered glass, natural stone, granite, quartzite, marble, quartz, wood, particle board, MDF board, HPL board, and solid surface materials.

[0074] Preferably, the material of the fifth sheet is the same as the material of the first sheet.

[0075] In a preferred embodiment of the present invention, the interlayer element comprises a sixth sheet located below the third sheet and a seventh sheet of aluminum located below the sixth sheet and above the second sheet, the sixth sheet being made of a material selected from the group consisting of ceramic materials, glass, porcelain materials, glass-ceramic materials, lacquered glass, natural stone, granite, quartzite, marble, quartz, wood, particle board, MDF board, HPL board, and solid surface materials. This embodiment is advantageous, for example, when adding additional elements that can fulfill both technical and aesthetic functions to the product comprising the layer element of the present invention. These additional elements can be, for example, skirts attached to the underside of the layer element.

[0076] Preferably, the seventh sheet of aluminium has a thickness between 0.1 mm and 4 mm, more preferably between 0.2 mm and 1 mm, even more preferably between 0.25 mm and 0.5 mm.

[0077] Preferably, the thickness of the intermediate third sheet of aluminum is greater than or equal to the thickness of the seventh sheet of aluminum, and more preferably, the thickness of the intermediate third sheet of aluminum is equal to the thickness of the seventh sheet of aluminum.

[0079] The function of this surrounding element of light-transmitting material is, on the one hand, to improve the light effect in the lateral periphery by acting as a diffuser, and, when two or more layer elements according to the invention are placed next to each other, to act as a joint through which light can pass, which, in addition to making it possible to hide the joint between the juxtaposed layer elements, also allows for greater freedom of arrangement of safety light elements in products incorporating the layer elements according to the invention.

[0080] Preferably, the peripheral element of optically transparent material extends over at least a portion of the lateral perimeter in a direction from the upper surface of the layer element towards the lower surface of the layer element.

[0093] [Detailed disclosure description] 1A-1C show a first embodiment of a laminar element according to the invention. In this first embodiment, the laminar element has an upper surface (11) visible during use, a lower surface (13) parallel to and opposite the upper surface, and a lateral perimeter (15). It is composed of three sheets: an upper first sheet (2) whose upper surface (21) forms the upper surface (11), a second sheet (4) with lateral segments (41) made of a light-transmitting material, and a third sheet (8). Depending on the desired final thickness, the first sheet may have a thickness between 2 mm and 20 mm, preferably between 3 mm and 12 mm. A thickness of less than 10 mm is particularly preferred, and a thickness of less than 8 mm, e.g., 5 mm, is even more preferred. Regarding the material of the first sheet, the first sheet is made of a porcelain material, but may also be made of other materials, such as ceramic materials, glass, glass-ceramic materials, lacquered glass, natural stone, granite, silica stone, marble, quartz, wood particle board, MDF board, HPL board, etc., depending on the intended use of the layer element. In this embodiment, the second sheet (4) of the layer element (1) comprises lateral segments (41) made of a light-transmitting material. In this particular embodiment, this light-transmitting material is a transparent polymer material, such as methacrylate or polycarbonate, which has advantageous mechanical and optical properties for producing the layer element according to the present invention for applications requiring high performance in terms of strength and light transmittance. In particular, transparent methacrylates or polycarbonates with various light transmittances can be used, as long as they allow light of sufficient intensity to be emitted and visible. As a design choice based on purely aesthetic, rather than technical, criteria, a translucent methacrylate or polycarbonate could be used in this case, which would allow scattering of the light coming from the lateral periphery of the layered element, thereby creating a gradient, continuous light effect at the edge of the illuminated area around the lateral periphery of the layered element.As already indicated, other alternative materials are also conceivable, such as transparent methacrylate or polycarbonate, which do not allow for such an aesthetic finish but which still perform the required technical function without any problems.The second sheet (4) has a thickness that can vary between 2 mm and 30 mm depending on the specific application of the layered element, preferably 10 mm if the layered element is intended to be used as a kitchen counter, and 15 mm if it is intended to be assembled into a step. An intermediate third sheet (8) of aluminum, 0.5 mm thick, is placed between the first sheet (2) and the second sheet (4). In this first embodiment of the invention, and as shown in Figures 1A and 1B, the lateral segments (41) of light-transmitting material have light-incident surfaces (45) oriented transversely relative to the layered element (1). This light-incident surface (45) corresponds to the lateral surface of the lateral segments (41) of light-transmitting material that faces away from the lateral perimeter (15) of the layered element. The light-transmitting side segment (41) also has a light-exiting surface (43), which is part of the side perimeter (15) and is opposite the light-incident surface (45). A light-emitting device (6) is positioned adjacent to the light-incident surface (45), such that light emitted by the light-emitting device enters the light-transmitting side segment through the light-incident surface (45) and exits the light-transmitting side segment through the light-exiting surface (43) so as to be visible to a user positioned facing the layer element (1). The light-emitting device can be any of a variety of options, such as individual LEDs spaced apart along the side segment (41) or an LED strip affixed along the length of the light-transmitting side segment (41) adjacent to the light-incident surface (45). In this particular embodiment, the light-emitting device (6) is an LED strip, as shown schematically in FIG. 1B. The LEDs are DC LEDs with a voltage of 12 or 24 volts, preferably 24 volts. To ensure sufficient light intensity, LED strips with an appropriate LED density per meter can be used, such as 250 LEDs per meter or more, preferably 300 LEDs per meter or more.As a design choice based purely on aesthetic rather than technical criteria, a density of 350 LEDs per meter or more, e.g., 400 LEDs per meter, is preferred in order to achieve a continuous light pattern and a gradient finish at the edge of the illuminated area on the side perimeter (15). As already mentioned, various light-emitting devices, such as individual LEDs or lower LED densities in the display area, are conceivable that do not allow for such an aesthetic finish but still perform the required technical function. In this embodiment, the first, second, and third sheets are in contact with each other and are bonded together, for example by adhesive, to form the layered element (1).

[0094] Other embodiments of layer elements according to the invention, which share many of the features described in the previous paragraphs, are presented below, and therefore only the different elements are described below, with reference to the description of the first embodiment for the common elements.

[0095] FIG. 2 shows a second embodiment of the present invention, in which the layer element 1 has a groove 17 formed in a side segment 41, and the light-emitting device 6 is mounted in this groove 17. This embodiment is advantageous, for example, when the layer element 1 is mounted on a furniture surface, such as a kitchen furniture countertop, because it allows the light-emitting device 6 to be accessible for maintenance or repair work. The groove 17 can also be a recess if located on a side end of the side segment 41. The groove 17 preferably has a polygonal cross-section, more preferably a rectangular cross-section as shown in FIG. 2, or a square cross-section. However, other cross-sections, such as a curved, arched, or semicircular cross-section, are also possible. In this embodiment, the light-entering surface 47 of the side segment made of a light-transmitting material is one of the walls defining the groove 17 with a rectangular cross-section, opposite the side perimeter 15 of the layer element. The groove (17) extends from the lower surface (13) of the layer element (1) partially through the second sheet (4) in the direction from this lower surface (13) to the upper surface (11) of the layer element. Alternatively, the groove can extend completely through the second sheet (4), allowing the intermediate third sheet of aluminum to be visible. This groove or recess can be created by machining the layer element (1) after the different sheets (2, 4, 8) have been bonded together. Preferably, the groove depth is such that it leaves at least 2 mm, preferably at least 4 mm, of the thickness of the second sheet (4). In particular, in this embodiment of the invention, the groove depth is 5 mm, leaving a thickness of 5 mm of the second sheet (4) if the layer element is intended for use as a kitchen countertop, and a thickness of 10 mm if the layer element (1) is intended for use as a step. The width of the groove (17) must be sufficient to accommodate a light-emitting device. In this embodiment of the invention, the groove or recess width is 10 mm. The location of the groove relative to the lateral periphery (15) of the layer element (1) can vary, but preferably the groove or recess (17) is made to be located at a distance of 1 mm or more from the lateral periphery (15), preferably between 1 mm and 12 mm, more preferably between 2 mm and 6 mm.In this embodiment, the groove is made approximately 6 mm from the lateral periphery (15) of the laminar element (1).

[0096] 3 shows a third embodiment of the layer element (1) according to the invention, in which the second sheet (4) of the layer element (1) extends in a direction parallel to the first sheet (2) over the entire surface occupied by the layer element (1) and is made entirely of a light-transmitting material, in particular methacrylate or polycarbonate, although other options as mentioned above are also possible depending on the performance that the layer element (1) must have. In this case, the second sheet (4) of methacrylate or polycarbonate performs a structural function in addition to its light-transmitting function, allowing the layer element to be mounted on a suitable support, such as the structure of kitchen furniture or the legs of a table, and thus suitable for use directly as a countertop.

[0097] Figures 4, 5 and 6 show embodiments of the invention in which the layer element has a fourth aluminum sheet (10) with the same thickness as the intermediate third aluminum sheet (8). In these embodiments, the grooves (17) also penetrate the fourth aluminum sheet (10). Regarding the dimensions of this fourth aluminum sheet (10), it has a thickness between 0.1 mm and 4 mm, preferably between 0.2 mm and 1 mm, more preferably between 0.25 mm and 0.5 mm. Furthermore, in the fourth aluminum sheet (10), the thickness of the intermediate third aluminum sheet (8) is greater than or equal to, and preferably equal to, the thickness of this fourth aluminum sheet (10).

[0098] Furthermore, a fourth embodiment of a laminar element according to the invention, shown in FIG. 4, adds to the embodiment shown in FIG. 3 a fourth sheet (10) of aluminum.

[0099] FIG. 5 shows a fifth embodiment of the present invention, in which the second sheet (4) comprises, in addition to a lateral segment (41) made of a light-transmitting material, a portion of the second sheet of support material that is continuous with the lateral segment (41) made of a light-transmitting material and extends over the remaining surface of the layer element (1). Examples of support materials for this portion of the second sheet (4) include wood, particle board, MDF board, and HPL board, the purpose of which is to provide rigidity to the layer element (1). The choice of material depends on the specific application. An advantage of this embodiment is that the layer element is already suitable for direct use as a countertop, assembled on a suitable support such as a kitchen cabinet structure or a table leg. This configuration also allows for greater flexibility in selecting the light-transmitting material for the lateral segment (41) of the second sheet (4).

[0100] 6 shows a sixth embodiment with an alternatively positioned recess (17), which in this case is made at the edge of the part of the second sheet (4) of support material, next to a lateral segment (41) of light-transmitting material, and the light-emitting device (6) is arranged next to a light-incident surface (45) that corresponds in part to the lateral surface of the lateral segment (41) of light-transmitting material, opposite the lateral periphery (15) of the layer element (1). In this sixth embodiment, the light-emitting device (6) is arranged in the recess (17) at the end that follows the lateral segment (41).

[0101] Figures 7 and 8 show alternative embodiments of the laminar element (1) according to the invention, in which a fifth sheet (12) is located beneath the second sheet (4). In the embodiment shown in Figure 7, the fifth sheet (12) is located beneath and in contact with the fourth aluminum sheet (10). In the embodiment shown in Figure 8, the fourth aluminum sheet (10) is removed, and the fifth sheet (12) is located beneath and in contact with the second sheet (4). The material of the fifth sheet (12) typically matches that of the first sheet (1) on the underside (13) of the laminar element (1) in order to maintain the same technical and aesthetic properties required by the specific application for which it is intended. This material is selected from the group consisting of ceramic materials, glass, glass-ceramic materials, lacquered glass, natural stone, granite, quartzite, marble, quartz, wood particle board, MDF board, and HPL board. Other materials are also possible, and the material of the fifth sheet can be different from that of the first sheet if required for a specific application. It is also possible to have this arrangement of five sheets in a layered element with lateral segments made of light-transmitting material and supporting portions of the second sheet (4) made of another material, as described above for the other embodiments.

[0102] 9 and 10 show alternative embodiments of the layer element (1) according to the present invention, including a surrounding element (18) made of a light-transmitting material, preferably made of the same material as the lateral segments (41). In particular, in these embodiments, the surrounding element is in the form of a methacrylate border, which may have a thickness of between 1 mm and 12 mm, preferably between 2 mm and 8 mm, and is glued to the lateral periphery (15) of the layer element (1) covering the light-exiting surface (43). Meanwhile, this surrounding element (18) can serve as a joint between different layer elements when multiple layer elements need to be attached to cover a larger surface. Furthermore, by being made of a light-transmitting material, in this case methacrylate, this surrounding element (18) also allows the light exiting through the light-exiting surface (43) of the methacrylate lateral segments (41), thereby concealing the joints between different layer elements that are often hidden in this type of assembly, and further improving the appearance. On the other hand, if the lateral perimeter to which the layer element (18) is adhered is used as the viewing side of the layer element (1), the methacrylate perimeter element (18) acts as a light diffuser that improves the aesthetics of the light effect.

[0103] Figures 11A and 11B show an embodiment including a skirt (20) attached to the underside (13) of the laminar element (1) and aligned with the lateral perimeter (15). This skirt (20) is preferably made of the same material as the upper first sheet (2) and can be directly glued to the underside (13) of the laminar element (1) with an adhesive, as shown in Figure 11A, and reinforced by brackets screwed to the skirt and the underside (13) of the laminar element. Similarly, the skirt (20) can be fitted into a recess made next to the lateral perimeter (15) of the laminar element (1), as shown in Figure 11B.

[0104] Figures 12A and 12B show alternative embodiments of the invention in which an additional sheet is present between the second sheet (4) and the third sheet of aluminum (8) so that the first sheet (2) and the third sheet (8) are in contact with each other, but the second sheet (4) is not in contact with the third sheet (8). In these alternative embodiments, a sixth sheet (14) is present below the third sheet of aluminum (8) for support, and a seventh sheet of aluminum (16) is present below the sixth sheet (14). In the embodiment of the invention shown in Figure 12B, a skirt (20) is also fixed to the bottom of the layer element (1).

[0105] 13A and 13B show an embodiment of a countertop (22) according to the invention. This embodiment relates to a kitchen countertop (22) with an integrated induction cooktop (PI) and sink (F). As can be seen in the enlarged view of the countertop's borders, the countertop comprises a layer element (1, 22) consisting of four sheets: a first sheet (2), a second sheet (4) with at least one lateral segment (made of methacrylic in this case), and third and fourth sheets (8, 10) of aluminum. A cross-sectional view of the front part of this countertop according to the invention is shown in FIG. 4 and corresponds to the view of the layer element (1) according to the invention described above. Furthermore, in this embodiment, the layer element (1) comprises a through-opening (24) that corresponds to the opening of the sink (F) when the sink is installed under the countertop.

[0106] A simplified example of an additional safety system that can be implemented in a product incorporating a layered element according to the present invention, particularly in a countertop of a kitchen piece incorporating an electromagnetic cooktop (PI) as shown in Figures 13A and 13B, is described in detail below. As a result of a light-emitting device included in the layered element according to the present invention, which is not visible in the figures but is present in the countertop of this embodiment, both the front of the kitchen piece and the side perimeter around the sink can emit light. The light-emitting device is connected to a temperature sensor and a control unit located within the electromagnetic cooktop. Thus, the light-emitting device indicates the countertop's temperature status by illuminating the side perimeter of the countertop in response to data captured by the temperature sensor and instructions programmed into the control unit. For example, the light-emitting device can emit a basic white light to clearly demarcate and visualize the boundaries of the countertop. When the electromagnetic cooktop (PI) is switched on, it can emit a red light to indicate that the electromagnetic cooktop is operating. This red light can remain lit while the electromagnetic cooktop is in use to indicate that the cooking area is above a certain temperature threshold, and can also remain lit after use until the cooking area temperature drops below a predetermined safety threshold. With regard to the sink (F), the layered element according to the present invention allows for lighting in areas that are often difficult to install due to the obvious safety reasons that make it difficult to incorporate electrical elements in areas where water is present. As an additional feature, the countertop according to the present invention allows for lighting underneath the countertop, for example, in a drawer (C), as shown in FIG. 13B.

[0107] FIG. 14 shows an embodiment of a step or rung (E) according to the present invention. As can be seen in the enlarged view, this step (E) comprises a layer element consisting of four sheets: a first sheet (2), a second sheet (4) of methacrylate with at least one lateral segment, and third and fourth sheets (8, 10) of aluminum, all of which, although not shown, have all the features of the layer element according to the present invention described above. In this case, the step can be equipped with a light sensor connected to a light-emitting device by a control unit. This allows the lateral perimeter of the step to be illuminated depending on the ambient light, thereby improving the visibility of the step in low-light conditions and providing an additional safety measure for the staircase without adversely affecting its technical and aesthetic characteristics.
