    DESCRIPTION
    IMPROVEMENT IN THE OBJECT OF THE PATENT "HINGE WITH LOCK POSITIONS FOR SEWER COVER"
    Technique Field
    The present invention concerns the field of hinges with locking positions for sewer covers, formed by a frame attached to a portion of frame hinge, and by a lid attached to a portion of lid hinge, obtaining a hinge from the mutual removable union of the two aforementioned hinge portions that allows the lid to pivot with respect to the frame between a closed position, an intermediate opening position in which the lid is locked vertically, and a maximum opening position.
    State of the art
    Sewer covers attached to a frame by means of a hinge, providing a closed position and a maximum opening position are widely known.
    Some solutions are also known that also provide an approximately vertical intermediate opening position.
    Additionally, the addition to a sewer cover of elastic arms with a long cantilever section whose end is elastically deformable is known, allowing the use of said elastic arms as retainers of the lid with the frame by the elastic force exerted by said ends of the arms Elastic Examples of this solution are for example WO8604624, WO2004015213A2 and CN2578393Y.
    However, these documents do not contemplate the integration of this elastic element together with the hinge, nor that said elastic arm produces an elastic force in a direction approximately perpendicular to said sewer cover.
    Brief description of the invention
    The object of the original patent, which for informational purposes is identified as the Spanish patent application number 201530088, which this document perfects concerns a hinge with locking positions for sewer cover, which allows an operator to open said sewer cover and keep it open without the risk of accidental closure. Said sewer cover proposed includes:

    • a horizontal frame surrounding an opening, said frame being provided with a hollow frame hinge portion;
    • a cover provided for a tight closing of said opening, the cover being provided with front and rear faces, and a complementary hinge portion complementary to the hollow frame hinge portion, allowing the lid to rotate around of an axis of articulation;
    • a retaining end of the hinge portion of the lid-shaped projection disposed at its furthest end from the lid;
    • an appendix of the frame hinge portion configured to enter geometric interference with a retaining end of the lid hinge portion, the lid being in the closed position, preventing upward displacement of the lid;
    providing, the interaction of the lid and frame hinge portions, three locking positions of the lid relative to the frame, a closed position, an intermediate opening position, and a maximum opening position in which said lid forms an angle of more than 95 ° with respect to the frame;
    It will be understood that the lid can refer to both a lid that completely closes the opening and a fence, for example a drain grate.
    The closing position is that in which the lid is coupled to the frame and completely seals the opening. The intermediate opening position is that in which the lid is open approximately 90 ° with respect to the frame, and therefore vertically, since in the whole document it is understood that ideally the frame will be in a horizontal position although its colocation in other positions. The maximum opening position is that in which the lid is fully open and can no longer be opened, its opening angle being greater than that of the intermediate opening position and therefore greater than 95 °. Typically this position has an opening angle of between 110 ° and 140 ° with respect to the frame.
    The lid is articulated with respect to the frame by coupling the lid hinge portion, which protrudes from the perimeter of said lid, with the hollow frame hinge portion, which forms a cavity in which said lid hinge portion is enter.
    In a novel way, the present certificate of addition proposes that the cover also includes a first protruding arm attached to a rear face of the cover, said first arm including a cantilevered portion that extends being the
    5

    distal end of the cantilever in geometric interference with the aforementioned appendix of the frame hinge portion, the lid being in a closed position, said first arm being subjected to elastic tension.
    Thus the first arm protrudes from the lid, which has a cantilever portion, preferably composed of the same material as the rest of the lid and manufactured simultaneously and jointly with the rest of the lid, the lid being and therefore also the arm a Only continuous body. By way of example, it is proposed that said cover and said first arm be composed of ductile iron or spheroidal graphite cast iron, since this material allows its fabrication molded and at the same time confers a lower fragility compared to the current foundry, and certain capacities improved elastic.
    Being a portion of the cantilever arm, and thanks to the elastic properties of the material that composes it in combination with the slenderness of said cantilever portion of the arm, it gives said arm some perceptible elastic properties. Therefore, the distal end of the cantilever portion, that is to say the end of the arm furthest from the union of the arm with the lid, admits a deformation and a sensitive displacement with respect to the lid opposing an elastic force against said elastic deformation. . Therefore said arm acts as a spring that pushes the cover against the frame thus ensuring an effective closure, and preventing the passage of people or vehicles on said cover produces movements, vibrations or noise by the movement of the cover with respect to the frame .
    According to an embodiment of the improvement, the aforementioned geometric interference between the distal end of the overhang and the aforementioned appendix of the frame hinge portion, being the lid in closed position, produces an elastic tension in the arm that generates with an effort whose main The component is of ascending vertical direction that is transmitted to the appendix, the frame being horizontal.
    To generate an effort in the mainly vertical upward direction, the aforementioned appendix must be located above the distal end of the overhang, preventing its displacement in the upward vertical direction to produce its deformation and generate said elastic tension of the arm.
    With the appendix above, the extraction of the arm is prevented, and the rest of the cover, in the vertical upward direction is impossible due to said geometric interference. For this reason it is proposed that the distal end of the cantilever of the arm be

    find farther from the perimeter of the lid than the axis of articulation. This feature allows the pivot to pivot the cover around said articulation axis producing its opening, the elements located farther from the perimeter of the lid that said articulation axis move in a downward direction. In this case the distal end of the cantilever of the arm descends away from the appendix and allowing the aforementioned opening of the lid.
    Additionally, the proposed improvement contemplates that said distal end of the arm overhang has at least one coplanar face with the retaining end of the lid hinge portion. In this way the same straight appendix can interact simultaneously with the retaining end and with the distal end of the overhang.
    It is also proposed that the lid hinge portion be composed of two spaced apart walls perpendicular to the articulation axis, said cantilever portion of the arm being confined between said two walls. In this way a compact construction of the lid hinge portion is achieved by also integrating said arm.
    Additionally, it is proposed that the cover also includes at least a second protruding arm attached to said rear face of the cover including said second arm a cantilever portion that extends, the distal end of the cantilever, in geometric interference with anchors provided in said frame with the lid being in carrada position, and the aforementioned being at least a second arm subjected to elastic tension. Said at least a second arm when the lid is closed is subjected to elastic tension, generating a force that keeps the lid firmly attached to the frame, preventing movements, vibrations or noise of the lid and the frame. To proceed with the opening of the lid, an upward force will have to be applied on the lid to produce its pivot around the axis of articulation, and to produce an elastic deformation of said at least one second arm that releases its distal end of the geometric interference with the mentioned frame anchors. Typically said deformation of the second elastic arms will occur in a horizontal direction.
    It will be understood that references to geometric position, such as parallel, perpendicular, tangent, vertical, horizontal, etc. they admit deviations of up to ± 5 ° with respect to the theoretical position defined by said nomenclature.

    Detailed description of an embodiment example
    According to an exemplary embodiment with a non-limiting character shown in Figs. 1 and 2, the present invention concerns a hinge with lock positions for sewer cover, including a frame 1 embedded in the pavement provided with a frame hinge portion 10 hollow in which two cylindrical barrels 11 facing and coaxial to an articulation axis E are included, and including a cover 2 defining an anterior face, the cover 2 being complementary to said frame 1 and being provided with a hinge portion of cover 20 intended to be coupled to the frame hinge portion 10, forming the proposed hinge, said frame hinge portion 10 protruding from the perimeter of the lid 2.
    The directions and positions will be described with the understanding that the frame 1 is in a horizontal position but only for the purpose of improving the understanding of the document, without representing a limitation to placing the frame 1 in a different position.

    Said frame hinge portion 10 has a box shape, having two walls perpendicular to the axis of articulation E that extend from the frame 1 and from which the corresponding pins 11 protrude, and a wall parallel to the axis of articulation E which joins the ends of said two walls enclosing an enclosure.
    An appendix 15 is placed on said wall parallel to the axis of articulation E.
    The lid hinge portion 20 protrudes laterally from the lid 2 itself, and extends downwardly by means of two side walls facing and perpendicular to the axis of articulation E. On the outer faces of said two walls, recesses forming two tracks are provided. 21 symmetric
    Said tracks 21 are provided to act as cams of the bearings 11, allowing the union and pivotal movement of the lid hinge portion 20 with the frame hinge portion 10.
    Furthermore, said lid hinge portion 20 has a retaining end 22 disposed at its furthest end with respect to the lid 2, in the form of a shoulder which is complementary to the aforementioned appendix 15 of the frame hinge portion 10, the end being retainer 22 in contact with appendix 15 preventing removal of the frame cover while the lid is in the closed position. The aforementioned retaining end 22 is composed in the present embodiment of two symmetrical retaining ends, the lid hinge portion 20 being composed of two spaced parallel walls, each provided with a track 21 and a retaining end 22.
    The cover 2 also integrates a first elastic arm attached to its rear face. Said first arm is composed of the same material as the lid, and is manufactured at the same time as the lid, the first elastic arm and the lid 2 being integral.
    Said first elastic arm will have a cantilever portion whose slenderness will confer perceptible elastic properties, thus allowing it to act, with certain limitations, as a spring.
    Said first elastic arm has a distal end (the end furthest from its union with the cover 2) said distal end being disposed in a position adjacent to the retaining end 22, namely said distal end is located between the two symmetrical retaining ends 22 before described, said cantilever portion of the first elastic arm being at least partially located between the two symmetrical walls that make up the lid hinge portion 20.
    The said distal end has at least one coplanar face with the retaining end 22 of the lid hinge portion 20, so that both the two retaining ends

    22 symmetrical like the distal end of the first elastic arm come into contact with the appendix 15 of the frame hinge portion 10 while the lid is in the closed position, producing an elastic deformation of the first elastic arm generating a tension that maintains the hinge portion of cover 20 pressed against the frame hinge portion 10.
    Said distal end is proposed to be farther from the perimeter of the lid than the articulation axis E. This feature allows, when opening the lid, all the elements disposed farther from the lid 2 than said articulation axis E to move in a downward direction. In this way the distal end of the first elastic arm will be separated from the appendix 15 allowing the opening of the lid 2.
    The contact between the distal end and the appendix 15 occurs in a horizontal or almost horizontal plane, admitting that said contact plane can be inclined ± 45 ° with respect to the horizontal position. This position of the contact plane allows to generate, due to elastic tension, an effort whose main component is of vertical direction.
    The present embodiment also includes two second elastic arms attached to the rear face of the cover 2, arranged symmetrically. Each of said second elastic arms has a joint with the lid, a slender cantilever portion and a distal end conferring said elastic properties on the arm similar to those of the first elastic arm. Each of the distal ends of the second elastic arms is provided to be coupled to an anchor provided in the frame 1 producing an elastic deformation of said second elastic arm and therefore creating an elastic tension that pushes the cover against the frame.
    The distal ends of said second elastic arms do not protrude from the perimeter defined by the cover 2, therefore when opening the cover 2 said distal ends also move upwards together with the cover 2. To produce the release of said distal ends of the respective anchors by means of said upward displacement, it is required that the elastic deformation of the second arms occurs in a direction parallel to the cover 2, unlike the deformation of the first arm that is proposed to be in a direction perpendicular to the cover 2 .
    The combination of the elastic force exerted on the cover 2 by the first and second arms retains the cover 2 firmly coupled against the frame 1, avoiding movements, noises or vibrations.
