Definitions

  • the present invention relates to improvements made to manhole covers in particular of generally circular general shape, of the type comprising a frame and a shutter pad supported by said frame, the manhole being provided with a hinged device removably linking the pad to the frame at the periphery thereof and authorizing the lifting of the buffer relative to the frame by pivoting around the hinged device.
  • Manholes of the same type are also known, in which the pad has two nipples as before and the frame is provided with profiled housings, receiving these nipples, so that the pad cannot leave the frame even in the event of internal thrust.
  • These known looks have the following drawbacks: - the housings provided in the frame for the passage of the nipples are always open even when the pad is in place; dirt can then penetrate there (these manholes are mounted on the roadways) and pile up in the bottom of the cavities with which the housings are provided, hampering or even blocking the opening of the tampon; - due to the large distance separating the two nipples from the pad, it is possible that, during opening, if the user exerts a directed force, not exactly in the opening axis, but slightly offset towards the right or to the left (which often happens during openings made using a crowbar), the pad gets across and gets stuck; if this jamming occurs during the automatic lifting of the tampon under the action of an internal
  • a look is also known whose pad has rounded bearing surfaces. Such a look has the following disadvantages: - the pad is put in place from below the frame and is therefore no longer removable after sealing; - the shapes of the support housings are complex and are difficult to mold; - given the eccentricities provided in the frame, there is a risk of rotation blocking of the pad following fouling.
  • the main object of the invention is therefore to remedy the above-mentioned drawbacks of known tilting buffer manholes and to provide an improved hinged manhole giving better satisfaction, as far as possible, to the various requirements of the practical, and in particular: - under the effect of possible upwelling, even if the tampon is raised automatically, it must not leave its housing; - the tampon must then close properly under the effect of its own weight only; - the buffer must not be offset to the side when it is opened, even when the force exerted to open it is not strictly perpendicular to its pivot axis; - the tampon must stand alone in the open position; - The pad must be able to be separated from the frame easily and at any time, without this separation being able to occur accidentally and inadvertently when the pad rests in the closed position on the frame or in a clearly ajar position.
  • the hinge device comprises at least one hinge, having substantially the general shape of a T, which comprises a housing having substantially the general shape of a T, formed in a peripheral region of the frame, and a projecting pivot, having substantially the general shape of a T, carried by a peripheral region of the tampon and engaged in said housing, the radially innermost part of the housing, corresponding to the leg of the T, constitutes a neck having a lesser depth than the parts of the frame which frame it radially, -
  • the radially outermost part of the housing, corresponding to the crossbar of the T has a depth greater than that of the neck and has, on the one hand, a first portion located radially inwards and adjoining the aforementioned neck and having , in radial section, a concave shape facing inwards, the longitudinal end parts of this first portion being overhung by retaining lips, and, on the other hand, a second portion located radially outwards
  • the pad is retained on the frame and cannot be detached from the latter accidentally and inadvertently when it is in the closed position, for example under the action of a suction phenomenon due to the passage of 'a vehicle ; on the other hand the buffer can easily be tilted to open the manhole.
  • the T-shaped housing provided in the frame and the protruding pivot T provided on the pad have fairly simple geometric shapes and the manufacture of the frame and the pad by molding (in particular cast iron) is not complicated.
  • the protruding pivot and the housing are arranged respectively on the pad and in the frame so that, when the manhole is closed and the pad rests on the frame, the pivot has no point of contact with the housing.
  • the pad rests on the frame by means of a sound-absorbing elastomer seal, there is no no contact between the metal parts of the frame and the buffer and the generation of noisy knocks of the buffer against the frame is avoided during the passage of vehicles over the manhole.
  • the hinge is unique, the part of the latter forming the leg of the T extending substantially radially and the opposite side faces, at the ends of the transverse branch of the T, of the pivot and of the housing are separated from each other by a minimum clearance in order to prevent jamming of the pad during its movement relative to the frame.
  • the T-shaped housing is made in the thickness of the frame.
  • the frame does not have any projection, both interior and exterior, and the gaze according to the invention can, without difficulty, be substituted for an earlier gaze of the same dimensions.
  • the respective dimensions of the housing and the pivot are such that the pad is retained, by double pressing of the pivot in the housing, in an open position forming an angle of approximately 105 to 110 ° relative to its closed position.
  • the manhole cover according to the invention is such that: -
  • the radially outermost part of the housing comprises a central zone extending substantially in the extension of the aforementioned neck, which has a substantially flat and horizontal bottom and two lateral zones framing this central zone, which each have the aforesaid first portion located radially inward and second portion located radially outward, -
  • the bottom of this first portion and the bottom of this second portion, in each of the lateral zones, are connected continuously to one another by a substantially flat and horizontal surface.
  • the second portion located radially towards the outside of each lateral zone is overhung by a retaining lip situated opposite the aforementioned retaining lip overhanging the first portion located radially inwards and projecting inwards from the outer wall of the frame.
  • the above-mentioned first portion located radially inwards has, in radial section, a polygonal shape extending over approximately 180 °.
  • the aforementioned polygonal shape consists, starting from the bottom, of a first face inclined by approximately 111 ° relative to the bottom, of a second face forming an angle of approximately 135 ° relative to the first face, and a third face forming an angle of approximately 10 ° below the horizontal, this third face constituting the lower face of the retaining lip.
  • the internal face of the frame located opposite the shutter pad is, in the region of the hinged device, provided with a chamfer at its upper edge.
  • the chamfer is inclined by about 45 ° relative to the vertical.
  • the frame 1 of the manhole according to the invention has any desirable shape (circular in the example shown), size and configuration (in particular for its upper face). It will be noted in particular that this frame, intended to be embedded in an appropriate soil (pavement for example), has, in a manner known per se, an inner annular projection 2 capped by a sound-absorbing seal 3 made of elastomer and intended to support a buffer 4 (partially shown in Fig. 4) when it is in the closed position.
  • a single housing 5 in the general shape of T in top view, open upward in the upper face of the frame and also opening into the interior of the frame.
  • the part 6 of the housing 5 located inwardly constitutes the leg of the aforementioned T and extends substantially radially by having a lesser depth than the rest of the housing; the inner part 6 of the housing 5 thus forms a neck between the inner zone of the frame and the part 7 of the housing located towards the outside.
  • This part 7 of the housing located towards the outside is elongated substantially transversely to the part 6 and forms the transverse bar of the abovementioned T; its depth is on the whole significantly greater than that of part 6.
  • This part 7 itself presents two distinct regions, namely: - A first region 8 located most inwardly and adjoining said part 6, this first region 8 having, in radial section (line II-II) a substantially semi-circular outline, for example in the form of an arc of circle extending over 90 ° at most in its median zone situated opposite the above-mentioned neck and over approximately 180 ° in its end zones and a depth substantially greater than that of part 6; towards its ends, the region 8 is overhung by lips 9 which frame a free space extending the part 6; - A second region 10 located most outwardly of the same longitudinal dimension as the region 8 but having a decreasing depth from the region 8 to the outer wall 11; in other words, the bottom surface 12 of the region 10 rises from the inside to the outside and is connected without a solution of continuity and with large radii of curvature on one side with a semi-cylindrical surface 13 delimiting the region 8 and on the other side with the outer wall 11; the second region 10 is open upwards over its entire length
  • this second region 10 is located radially outward belonging to the radially outermost part 7 of the housing, and has a depth less than that of the above first region 8, while the bottom 12 of the second region 10 slopes down towards the bottom 13 of the above first portion 8 located radially forward.
  • the manhole buffer 4 has any desirable shape (discoid in the example shown), size and configuration (in particular for its upper face), in accordance with the shape, size and configuration of the frame to which he is associated.
  • this pad has, in a manner known per se, a peripheral annular bearing surface 14 intended to rest on the annular projection 2 covered with the sound-absorbing seal 3 and that it also has an annular skirt 15, making projection below its underside, which bears against the annular seal 3 and prevents the pad from being moved radially relative to the frame 1 when the pad is in the closed position.
  • a pivot 16 having the general configuration of a T dimensioned to cooperate with the housing 5 of the frame 1, protrudes radially on the periphery of the pad 4.
  • the pivot 16 has a portion of link 17 extending radially and connected to the buffer, corresponding to the leg of the T, and a pivot shaft part 18 extending transversely to the end of the connection part 17, and corresponding to the crossbar of the T
  • the pivoting shaft part 18 has an approximately cylindrical general shape with a diameter substantially smaller than the diameter of the first region 8 of semi-circular section of the housing 5 of the frame; however, this shaft has a flat 19 formed longitudinally and extending substantially parallel to the main faces of the pad, the transverse dimension of the pivot shaft part 18, perpendicular to the flat 19, being less than the upward opening of region 10 of housing 5 of the frame.
  • the respective lengths of the pivot shaft part 18 and of the outer part 7 of the housing 5 are such that the opposite facing faces have a minimum clearance allowing the pivoting of the buffer relative to the frame, but preventing the jamming of the tampon when lifting it.
  • Figs. 6 to 9 show the pivot 16 engaged in the housing 5 in different relative functional positions of the buffer 4 and of the frame 1.
  • Fig. 6 shows the pad 4 in the closed position on the frame 1. Note that the pivot 16 is connected to the pad 4 so that, in this closed position, the pivot 16 is not in contact with the walls of the housing 5 , in order to avoid noisy bumps of the buffer against the frame during the passage of a vehicle. In this position, the pivoting shaft part 18 extends, at least in part, under the overhanging lips 9, which therefore oppose the exit of the pivot 16 from the housing 5.
  • the pivot 16 When the pad 4 is lifted by being grasped in the middle, the pivot 16 lowers in the housing 5 until the shaft part 18 comes into contact with the bottom surface 12 of the housing 5. The pad pivots then around the shaft part 18 bearing on the surface 13 at the same time as the shaft part 18 is brought back by gravity towards the deepest zone (connection of the surfaces 12 and 13) of the housing due to the inclination of the surface 12 as shown in FIG. 9; in this figure, it is better to see that the part 18 of the pivot 16 is supported only by its ends on the bottom surface 13 of the housing.
  • the pad 4 remains in the open position with an inclination of 15 to 20 ° relative to the vertical (rotation of 105 to 110 °), occupying the position shown in FIG. 7, the pivot 16 resting on one side by its connecting part 17 against the upper edge of the wall 11 of the frame and on the other side by its connecting shaft part 18 against the underside of the lips 9 .
  • the pad is arranged vertically: the shaft part 18 can then engage in the opening overhanging the second portion 10 of the outer part 7 of the housing 5, as shown in FIG. 8.
  • a single housing 5 ⁇ is provided in the thickness of the frame 1 ⁇ .
  • Said housing 5 ⁇ has a general shape of T seen from above, open upwards in the upper face of the frame and also opening towards the inside of the frame.
  • Part 6 of the housing 5 ⁇ located inwardly constitutes the leg of the aforementioned T and extends substantially radially by having a lesser depth than the rest of the housing; the inner part 6 of the housing 5 ⁇ thus forms a neck between the inner zone of the frame and the part 7 ⁇ of the housing located towards the outside.
  • This part 7 ⁇ of the housing located towards the outside is elongated substantially transversely to part 6 and forms the transverse bar of the abovementioned T; its depth is on the whole significantly greater than that of part 6.
  • This part 7 ⁇ itself presents three distinct circumferentially zones: a central zone 21 extending radially from the part 6 to the external partition 11 of the frame and having a flat and horizontal bottom 22; and - two lateral zones 23 located on either side of the central zone 21 and each having a bottom 24 which can be located at a level substantially higher than that of the bottom 22 of the central zone 21, as shown in Figs. 11 and 12 (however, this provision is not mandatory and funds 24 and 22 can be located at substantially identical levels).
  • the two lateral zones 23 serve as housings receiving the ends of the pivot shaft part 18 of the pivot 16 of the pad 4.
  • Each of the lateral zones 23 is arranged so that it itself comprises two distinct regions: - A first region 8 located radially inwardly and adjoining said part 6, this first region 8 having, in radial section, a concave contour and a depth substantially greater than that of part 6; towards its upper end, the region 8 is overhung by a lip 9; - A second region located radially outwardly of the same longitudinal dimension as the region 8 and overhung, towards its upper end, by a lip 25 located opposite the lip 9 above.
  • Fig. 11 represents a first possible configuration of the part 7 ⁇ of the housing 5 ⁇ : the first region 8 is here delimited, radially inwards, by a wall 26 which is concave with continuous curvature from the bottom 24 of the part 7 ⁇ to the lower end of the lip 9.
  • the wall 26 has a lower part 26a in the form of a portion of cylinder substantially of revolution having a large radius of curvature (relatively), surmounted by an upper part 26 b in the form of a portion of cylinder substantially of revolution having a relatively smaller radius of curvature.
  • the different walls delimiting the part 7 ⁇ of the housing 5 ⁇ namely the wall 26, the bottom 24 and the wall 27 delimiting the second region 10 radially outward
  • Fig. 12 shows a second possible configuration of the part 7 ⁇ of the housing 5 ⁇ .
  • the first region 8 is delimited, radially inwards, by a wall 28 of polygonal section constituted, for example, by three successive faces: - A first lower face 28a making an angle of approximately 111 ° relative to the bottom 24; - a second intermediate face 28b forming an angle of about 135 ° with respect to the first face 28 a and, a third face 28c forming an angle of approximately 10 ° below the horizontal, this third surface constituting the underside of the aforementioned lip 9, these three faces being connected together and with the bottom 24 by portions of cylindrical surface of revolution.
  • the part 7 ⁇ of the housing 5 ⁇ is constituted as indicated above with reference to FIG. 11.
  • the shutter plug of the gaze it is arranged as indicated in the first exemplary embodiment in particular as regards its pivot in T which is engaged in the housing 5 ⁇ of the frame.
  • the T-shaped pivot of the tampon is no longer, during the opening or closing of the tampon, guided on the inclined ramp formed by the bottom 13 .
  • a chamfer 29 is therefore provided, in the region surrounding the housing 5 ⁇ , on the upper part of the inner face of the frame.
  • This chamfer has an inclination of about 45 ° relative to the vertical, that is to say it is approximately parallel (in the exemplary embodiment of FIG. 12) to the surface 28 b supra.
