    Cover for use on public roads
    The present invention relates to a cover for use on public roads, which must withstand the passage of people and vehicles over it. Background of the invention
    The covers for use on public roads, for example sewer covers, are widely known to the general public, usually located on the street floor in any city, to typically cover access to public sewer, as well as access to wiring tunnels, etc.
    Typically, such covers are made of metallic materials, the most common being the covers made of cast iron (iron with more than 2% carbon).
    A problem associated with sewer covers is that it is a common object of theft as it is made of cast iron and can be sold by weight, since it can be recycled as scrap metal.
    There are currently other sewer covers, in addition to those made in foundry, whose characteristics already make them not to be theft (either by low weight, non-recyclable materials, etc.). However, such sewer covers are more expensive than the usual cast iron sewer covers.
    Another problem associated with the sewer covers is that after a while they may end up moving inside their housing, causing noise and bumps, a very annoying case for the neighbors surrounding said lid.
    Therefore, it is evident the need to create a type of covers for sewers and underground tunnels that are not subject to theft and whose manufacturing process is cheaper than conventional processes, also giving the possibility of avoiding noise.
    Another objective of the present invention is to provide sewer covers with functionalities
    extra, in addition to acting as a simple cover. Description of the invention
    With the cover of the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
    The cover for use on public roads according to the present invention comprises at least one outer body of plastic material that houses at least one reinforcement, said reinforcement being metal or ceramic.
    Advantageously, said reinforcement can be in the form of bars, wires, wires, grating, profiles, sheet, cable and / or rope and, for example, said reinforcement is made of steel or aluminum, or alumina, silicon carbide, silicon nitrate , zirconia, sialon or fiberglass, carbon fiber or aramid fiber, although it could be of any suitable material that has sufficient strength.
    According to two alternative embodiments, said outer body can define a substantially flat continuous upper and lower surface.
    Advantageously, the cover for use on public roads according to the present invention may comprise a housing, for example, to house an electronic identification module and / or electronic sensors, which may be of movement or counting.
    If desired, the density of said at least one reinforcement is greater in the central part of the lid than in the rest of the lid.
    Furthermore, advantageously, the cover according to the present invention may comprise a cushion seat placed in its part that is in contact with the surfaces where it rests.
    The lid according to the present invention has at least the following advantages:
    - It is lighter than conventional covers, being made with less metal and lighter materials;
    - It is not subject to theft, not being easily recyclable;
    - It offers the possibility of informative additions, for example by means of RFID or NFC technology, to give technicians information about the facilities under said cover, repair history, etc.
    - It offers the possibility of smart additives, for example motion and counting sensors. Brief description of the drawings
    To better understand how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, several practical cases of realization are represented.
    Figures 1 to 3 are perspective views of three embodiments of the lid according to the present invention, the outer body being partially removed so that the inner reinforcements can be seen;
    Figure 4 is a plan view of an embodiment of the cover according to the present invention where the density of the reinforcements is appreciated;
    Figure 5 is a perspective view of an embodiment of the lid according to the present invention, comprising an interchangeable plate; Y
    Figure 6 is a sectional view of the seating area of the lid according to the present invention in its use position. Description of preferred embodiments
    The cover for use on public roads in accordance with the present invention comprises one
    or several reinforcements 1 joined by an external body 2 of plastic material, for example by injection, resulting in a single indivisible object.
    According to a preferred embodiment, the covers for use on public roads object of the present invention are made with injected thermoplastics forming an external body 2 on a metal grid as a reinforcement 1.
    These caps can be of different shapes (round, square, irregular, etc.), depending on the shape of the mold, adapting to different applications.
    Said covers may have one or more reinforcements 1, placed inside the outer body 2 of plastic material, to offer the necessary mechanical resistance to the cover. These reinforcements can be:
    - metal bars; welded or not welded;
    - wires
    - threads
    - metal bars; welded or not welded;
    - sheet metal; cut, stuffed, punched, etc .;
    - bonded metal profiles;
    - steel wires;
    - steel cable networks
    - fiberglass cables or ropes, carbon, aramid, etc .;
    - fiberglass, carbon, aramid nets, etc .;
    - ceramic profiles (alumina, silicon carbide, silicon nitrate, Zirconia, Sialon, etc.);
    - ceramic sheets (alumina, silicon carbide, silicon nitrate, Zirconia, Sialon, etc.); or
    - Any combination thereof.
    Said reinforcements 1 can also offer both regular and irregular distribution, for example, offering a higher reinforcing density 1 in the center of the lid, as it is a point of greater mechanical solicitation.
    According to a preferred embodiment, said cover has a housing 3 for an identification element, said identification element being an electronic identification element in which information about the cover can be written, (for example the facilities below, the history of maintenance, etc.) and that is in two-way communication with a receiving device (not shown in the figures). Said receiving device, used by the maintenance technician, public works, etc. it can be a generic device, for example a mobile smart phone, or a particular device, designed specifically for this use.
    Preferably, said electronic identification module would be an RFID tag, or NFC.
    According to a preferred embodiment, the lid according to the present invention has a housing 3 for electronic motion or counting sensors. This would allow taking advantage of these elements to make, for example, traffic controls and statistics.
    According to a preferred embodiment, the cover according to the present invention has a seat 4 of cushioning material to avoid noise when vehicles pass over it. Advantageously, the caps according to the present invention can be manufactured with a highly automated process, being an automatic plastic injection process, with a previous process of inserting the reinforcement into the mold, which can be easily carried out by using robots. In this way, it is also possible to reduce the cost of manufacturing said sewer covers.
    Advantageously, the lids according to the present invention have a lower weight than conventional lids, using less amount of heavy material, and lighter materials (plastic instead of steel). This fact facilitates its assembly and maintenance, as fewer operators are needed to handle each piece.
    Advantageously, the covers according to the present invention can have another upper housing 5, to put interchangeable plates 6 with different customizable logos, with the name of town halls, companies, pedestrian information, etc. Said interchangeable plates 6 can be of different colors.
    Advantageously, the covers according to the present invention may have lower wedges 7, in conjunction with the cover frame, to cushion the impacts received by said cover. Optionally, a lower gasket 8 can be installed to help this end.
    Although reference has been made to several specific embodiments of the invention, it is apparent to one skilled in the art that the described lid is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
