Definitions

  • the present invention relates to a manhole cover for an underground structure, such as a sewer for example, said cover comprising a frame fixed to the ground and a movable lid.
  • the frame has a passage opening with a non-circular inner edge which however has a span in any direction equivalent to a pre-established diameter sufficient to allow the passage of a person. In many places, this equivalent diameter is established by regulations.
  • Manhole covers for underground structures of the type comprising a frame and a lid, are well known in the state of the art.
  • the frame is suitable for being fixed to the ground in relation to said manhole and comprises a passage opening to provide access therethrough, and the lid is configured to be coupled to the frame covering said passage opening.
  • Patent US-A-4840514 discloses a cover of the type described above in which the lid and the frame comprise respective hinge elements cooperating to allow rotating the lid with respect to the frame about a horizontal axis between a closed position, in which the lid is coupled to the frame covering the passage opening, and an open position, in which the lid is inclined backwards at a certain angle in relation to a vertical position thus leaving the passage opening clear.
  • the lid is stable in said open position.
  • the hinge elements allow the lid to be separated from the frame by moving it vertically upwards.
  • the frame and/or the lid include a notch in which an end of a crowbar is inserted when the lid is in the closed position to allow the start of opening the lid.
  • the lid Once the opening has started, the lid must be gripped with the hands to manually lift it up to the open position, which, due to the relatively heavy weight of the lid, requires a great effort and involves a serious risk of getting ones' fingers caught.
  • Patent US-A-4650232 describes an especially designed tool for being used as a crowbar to start opening the lid of a manhole cover for an underground structure and as a lever arm to lift the lid and drag it out of the passage opening, though in this case the lid is not hinged to the frame.
  • a drawback of this tool is that it is considerably large sized and must be transported to the location of the cover to be opened.
  • Patent US-A-5911537 discloses a lid for a manhole cover for an underground structure having a thickness that progressively decreases from the center towards the periphery to provide the lid with sufficient resistance to withstand rolling transit when the cover is installed, for example, in a road.
  • a drawback of this solution is that it considerably increases the weight of the lid.
  • Patent EP-A-1769125 describes a lid for a manhole cover of an underground structure comprising a relatively thin plate provided with a structure of ribs projecting from a lower surface of the plate.
  • the structure of ribs comprises inner ribs connected at their ends forming a regular hexagon and radial ribs extending from the vertexes of said hexagon to the periphery of the plate.
  • the inner ribs have a determined height, and the height of the radial ribs progressively decreases from the inner ribs to the periphery.
  • the mentioned patent EP-A-1769125 also describes pressure closure members comprising a protrusion located at the free end of a spring arm connected to the lid and cooperating with a corresponding protrusion formed in the frame to retain the lid in the closed position with respect to the frame.
  • a drawback of these pressure closure members is that they are located in a position that is diametrically opposed to the hinge device, and they are unable to retain the lid pressed against the frame in the area adjacent to the hinge. This can be the cause of noises produced by the play of the hinge elements when the lid is passed over by rolling transit.
  • NL 7 114 782 A discloses a manhole cover according to the preamble of claim 1.
  • both the frame and the lid for manhole covers of underground structures are made of ductile cast steel, which, in combination with the dimensions necessary to provide a passage opening sufficient to allow the passage of a person, means that the weight of the lid and of the frame is considerably high.
  • the passage opening of the frame is generally circular and its magnitude is determined by a minimum diameter, generally established by regulations, sufficient to allow the passage of a person.
  • the present invention contributes to mitigating the foregoing and other drawbacks by providing a manhole cover for an underground structure of the type comprising a frame and a lid, where said frame is configured to be fixed to said manhole and comprises a passage opening sized to allow the passage of a person therethrough, and one or more seats to bear said lid covering said passage opening.
  • the cover of the present invention is characterized in that the passage opening of the frame has an inner edge in the form of a first polygon having convex curved sides in which a first distance between two first parallel geometric lines tangent to opposite points of said inner edge is never less than a pre-established equivalent diameter sufficient to allow the passage of a person no matter what the direction of said two first parallel lines, and the lid has an outer edge in the form of a second polygon having convex curved sides geometrically similar to said first polygon having convex curved sides.
  • the inner edge of the passage opening of the frame has the form of a first non-circular curve of constant width, in which said first distance between two first parallel geometric lines tangent to opposite points of said inner edge is constant no matter what the direction of said two first parallel lines
  • the outer edge of the lid has the form of a second non-circular curve of constant width, in which a second distance between two second parallel geometric lines tangent to opposite points of said outer edge is constant no matter what the direction of said two second parallel lines, where said first and second curves of constant width are geometrically similar.
  • the aforementioned first distance between said two first parallel geometric lines tangent to opposite points of the inner edge of the passage area of the frame is equivalent to the diameter of the passage area of the frame
  • said second distance between the two second parallel geometric lines tangent to opposite points of the outer edge of the lid is equivalent to the diameter of the outer edge of the lid
  • said first and second curves of constant width are respectively first and second regular polygons having geometrically similar convex curved sides, preferably with rounded vertexes in a geometrically similar manner.
  • Any curve of constant width defined by a regular polygon having curved sides, either with or without rounded vertexes, has a perimeter and area that are less than the perimeter and area of a circumference of equivalent diameter.
  • the frame of the cover of the present invention with the inner edge of the passage opening in the form of the first curve of constant width has a perimeter and area that are less than that of a circular frame of equivalent diameter. Accordingly, to manufacture the frame of the cover of the present invention a smaller amount of material will be necessary compared to a conventional circular frame of equivalent diameter, and its weight will be less.
  • the lid of the cover of the present invention with the outer edge in the form of the second curve of constant width has a perimeter and area that are less than that of a circular lid of equivalent diameter. Accordingly, to manufacture the lid of the cover of the present invention a smaller amount of material will be necessary compared to a conventional circular lid of equivalent diameter, and its weight will be less.
  • the base polygons for the first and second curves of constant width are selected from first and second equilateral triangles, first and second regular pentagons and first and second regular heptagons.
  • the first and second curves of constant width are pentagons having geometrically similar convex curved sides, and more preferably pentagons having geometrically similar convex curved sides and rounded vertexes. The triangle is discarded as the base polygon because it provides an excessive reduction of the passage area and the heptagon and other polygons having a larger number of sides has been discarded because they provide insufficient weight reduction.
  • said second distance or second equivalent diameter of the outer edge of the lid is greater than said first distance or first equivalent diameter of the inner edge of the passage opening of the frame, which assures that in no position will the lid be able to pass through the passage opening of the frame.
  • the lid has an extendable handle installed on an inner face thereof which can be moved between a retracted position, in which said extendable handle does not project from the outer edge of the lid, and an extended position, in which the extendable handle projects from the outer edge of the lid. Therefore, when the extendable handle is in the retracted position, the lid with the extendable handle can be placed in the closed position with respect to the frame.
  • the lid is articulated to the frame by a hinge device and when the extendable handle is in said extended position, it provides a grip member and a lever arm on one side of the lid opposite said hinge device which allows lifting the lid, rotating it about a horizontal axis with respect to the frame applying less force than what would be necessary without the extendable handle.
  • the frame preferably comprises lower pressure closure members and the lid comprises other corresponding upper pressure closure members.
  • the aforementioned upper pressure closure members of the lid lock with said lower pressure closure members of the frame retaining the lid in the closed position with respect to the frame.
  • the lid can be placed in an ajar position, in which the upper pressure closure members of the lid are supported on the lower pressure closure members of the frame, whereby the lid stays in said ajar position with sufficient clearance with respect to the frame to allow the extendable handle to be gripped and moved between said retracted and extended positions without risk of getting ones' fingers caught.
  • the lid and/or the frame have a recess configured to receive an end of a conventional crowbar that can be used to move the lid from the closed position to the ajar position.
  • At least one of the lower pressure closure members of the frame and a corresponding one of the upper pressure closure members of the lid in the cover of the present invention are located adjacent to the hinge device.
  • the mutually locked upper and lower pressure closure members keep the lid pressed against the frame also at the side corresponding to the hinge device and thereby prevent noises produced by the play of the elements of the hinge device when the lid is passed over by rolling transit.
  • the second distance or second equivalent diameter of the outer edge of the lid is slightly less than said first distance or first equivalent diameter of the inner edge of the passage opening of the frame, and the lid comprises protrusions projecting radially from the outer edge thereof.
  • the frame comprises box-shaped elements located adjacent to and above the inner edge of the passage opening, and the aforementioned protrusions of the lid fit in said box-shaped elements of the frame when the lid is in a closed position with respect to the frame.
  • the lid is articulated to the frame by a hinge device, and one of the protrusions of the lid, which is located on one side of the lid opposite said hinge device, has a recess configured to receive an end of a conventional crowbar which can be used to start opening the lid when it is in the closed position.
  • the lid has three of said protrusions distributed regularly around the outer edge thereof and peripheral ribs projecting from an inner face of said protrusions and extending therealong parallel to the outer edge of the lid.
  • inner ribs which are connected at their ends forming a polygon centered with respect to the outer edge of the lid, and three pairs of intermediate ribs.
  • the two intermediate ribs of each pair are connected at one of their ends to said inner ribs and at their other end to opposite ends of one of said peripheral ribs of a corresponding protrusion.
  • the height of the inner ribs is greater than the height of the peripheral ribs, and the height of the intermediate ribs progressively decreases from the inner ribs to the peripheral ribs.
  • the peripheral ribs When the lid is in the closed position, the peripheral ribs are supported on the seats formed in the box-shaped elements of the frame, and the intermediate ribs transmit the loads applied on the lid, for example by the rolling transit, to the peripheral ribs and to the frame.
  • This arrangement of reinforcement ribs has been proven to provide the lid with greater strength against forces perpendicular to the upper surface thereof compared to lids with ribs arranged in radial directions distributed at equal angular intervals around it.
  • the polygon formed by the inner ribs is a regular hexagon and the two intermediate ribs of each pair are mutually parallel.
  • both the frame and the lid of the cover of the present invention are one-piece bodies obtained by molding ductile cast steel.
  • reference numeral 100 generally designates a cover (shown as a whole in Figs. 1 and 2 ) according to a first embodiment of the present invention, which comprises a frame 10 (shown individually in Figs. 3 to 6 ) and a lid 50 (shown individually in Figs. 7 to 11 ).

  • This second distance D2 is equivalent to a diameter of the outer edge 51 of the lid 50.
  • the second curve of constant width of the lid 50 is geometrically similar to the first curve of constant width of the frame 10, therefore in the embodiment shown the second curve of constant width of the lid 50 is a pentagon having convex curved sides and rounded vertexes.
  • the second distance D2 equivalent to the outer diameter 51 of the lid 50 is slightly less than the first distance D1 equivalent to the diameter of the inner edge 14 of the passage opening 11 of the frame 10, such that the cover plate 61 of the lid fits inside the upper portion of the perimetral tubular wall 19 of the frame 10.
