Definitions

  • the present invention relates to road parts such as manholes or manholes for sidewalks, of the type comprising a removable cover resting, in the closed position, in a frame sealed in the ground or on a support structure.
  • the present invention relates to means for removably securing a covering piece of the flat or concave grid type, plate or other, of generally polygonal shape, to a frame cooperating with said piece.
  • the covering part according to the present invention will have in plan a general triangular, square, rectangular or trapezoidal shape.
  • the present invention therefore aims to overcome these drawbacks.
  • the object of the present invention is, for this purpose, a roadway part comprising a rigid covering part and of generally polygonal shape, of the flat or concave grid type or covering plate, cooperating with a frame by means of means intended to removably secure said covering piece upwards to said frame, these means comprising at least one elastic member positioned in a housing open towards the inside of the frame and arranged in the middle region of one of the side faces of the frame , at least one hooking spout secured to the internal lateral face of the frame opposite to that where the elastic member is located, a finger secured to the covering part, the lower end of which has a bead which engages by cooperation with said hooking spout, and a bar oriented downwards and integral with the covering piece, which, when said covering piece ent is placed in the frame, that is to say in the closed position, bears against the face facing inward of the elastic member, the latching beak then being in the snapped-in position with the finger of the cover piece.
  • the road part shown in FIG. 1 consists of a frame 1 and a removable cover piece forming a cover.
  • the covering part chosen for this particular embodiment is a hinged planar grid 2.
  • the frame 1 and the grid 2 are both, in plan, of generally rectangular shape.
  • the frame 1 (Fig. 1 to 5) comprises a vertical skirt 3, provided at its periphery with a sole 4 intended to transmit the load and to seal the frame in the ground or on a support structure such as concrete for example .
  • each of these widenings 8A, 8B is formed an opening 9A, respectively 9B, of longitudinal direction the axis Y-Y, the opening 9B of the widening 8B being longer than the opening 9A of the widening 8A.
  • openings 9A, 9B are opposite one another and have in section, as shown in FIG. 4, a section having the general shape of a triangle with rounded apices, thus revealing in its vertical part most internal to the frame 1 a substantially oblong vertical portion, and in its lowest part, a substantially oblong horizontal portion.
  • the skirt 3 is terminated by a side face 10 opposite and parallel to the side face 7.
  • the lateral face 10 comprises, at its ends, two hooking nozzles 11 projecting towards the inside of the frame 1, integral with the internal face of the top of the skirt 3 and having in cross section, considering FIG. 4, a double cam comprising an upper ramp 11A inclined downwards, that is to say towards the base of the frame 1, and a lower ramp 11B inclined upwards, that is to say towards the top of the frame 1, l 'intersection of these two ramps 11A and 11B defining a crest line 12 parallel to the axis YY.
  • Each of the lateral faces 5, 6, 10 of the skirt 3 has, in its central region, two support studs 13, projecting towards the inside of the frame 1 and with upper reach 14 parallel to the plane of the frame 1.
  • Each of the lateral faces 5, 6 of the skirt 3 has, projecting towards the inside of the frame 1, two studs of support at higher range parallel to the plane of the frame, one of which 15 is located near the end close to the lateral face 10, and consequently close to the hooking nozzles 11, and the other 16 is located in the opposite corner.
  • the support pads 16 are, at one end of their upper reach, secured to the lateral face 7 of the skirt 3, the upper face of their upper reach, parallel to the plane of the frame, being situated, considering FIG. 5, at a level lower than the openings 9A, 9B.
  • the lateral face 7 has, in its central region, and preferably centered, a support pad 17 with upper reach 18, the upper face 18A and the lower face 18B, considering FIG. 5, are parallel to the plane of the frame 1.
  • This upper reach 18 has, considering Figs. 3 to 5, a centered recess 19, open towards the inside of the frame, of generally rectangular shape, thus dividing the upper surface 18 into two protuberances 20A, 20B linked together by a longitudinal branch 21, parallel to the axis YY, and integral with the side face 7 of the skirt 3.
  • the lower face 18B is extended at the inner ends of the protrusions 20A, 20B, parallel to the lateral face 7, by a lip 22 projecting vertically towards the base of the frame 1.
  • the median region of the lateral face 7 is extended towards the inside of the frame 1 by a longitudinal protrusion 23, parallel to the plane of the frame, of generally rectangular shape integral with the internal face of the skirt 3 and coplanar with the sole 4 which, in considering Figs. 3 to 5, is positioned between the protrusions 20A and 20B, that is to say under the recess 19, the ends inside the frame 1 and parallel to the face 7 of the protrusions 20A, 20B and the protuberance 23 being located in the same vertical plane.
  • the upper face of the protuberance 23 extends in the median region from its innermost end to the frame 1, and parallel to the lateral face 7, by a lip 24 projecting vertically towards the top of the frame 1, this lip 24 preferably being centered relative to the transverse ends 23A and 23B, parallel to the axis XX, of l outgrowth 23.
  • the lips 22 and 24 are such that the upper face of the lip 24 is situated at a lower level than the lower face of the lip 22.
  • the elastic member 26 is constituted by a spring.
  • this elastic member 26 has the general shape of a rectangular parallelepiped having on the one hand, at its transverse ends, two upper notches 27A, 27B intended to cooperate respectively with the protuberances 20A and 20B each provided with their end lip 22, and on the other hand, at the base of a longitudinal end, a lower notch 27C intended to cooperate with the lip 24 of the protrusion 23.
  • the elastic member 26 When the elastic member 26 is positioned in its housing 25, its lower face rests in part on the upper face of the protrusion 23, and its upper face is placed in the recess 19, and this at a level between the lower face 18B and the upper face 18A of the upper surface 18; the vertical face of the elastic member 26 opposite to that where the lower notch 27C is located is then positioned, by its apex, facing the longitudinal branch 21 of the support pad 17.
  • the elastic member 26, by the particular arrangement of the lips 22 and 24 and of the parts supporting the said lips is thus trapped in a perfectly stable manner in its housing 25.
  • the support pads 13, 15, 16 and 17, projecting towards the inside of the frame 1, are such that the upper faces of their upper spans, parallel to the plane of the frame 1, are coplanar and thus constitute flat surfaces on which the grid 2, in the closed position, will come to bear.
  • Grid 2 considering Figs. 1 and 2, consists of a series of bars 28, parallel to the axis YY, and interconnected by at least two spacers 29, parallel to the axis XX, two of the spacers 29 resting in the closed position by their ends, on the flat upper surfaces of the support pads 13 and 17 of the side faces 10 and 7 of the frame 1.
  • the bars 28, regularly spaced and ending in two end bars 28A, 28B, are positioned so that two of them rest, in the closed position, via their ends, on the flat upper surfaces of the support pads 13 of the side faces 5 and 6 of the frame 1.
  • the end bar 28A located near the lateral face 10 of the frame 1, rests, in the closed position, by its ends, on the flat upper surfaces of the support pads 15 of the frame 1, each of its ends extending towards the outside of the grid, parallel to the axis XX, by a finger 30 projecting downward, substantially perpendicular to the plane of the grid.
  • the fingers 30 terminate, at their lower end, by a bead 31 comprising a ramp 31A inclined downwards, directed towards the outside of the grid 2, and a lower surface 31B substantially parallel to the plane of the grid 2, the ramp 31A being connected to the surface 31B via a substantially rounded surface 31C.
  • the ramps 31A of the fingers 30, the inclination of which corresponds to that of the ramps 11B of the attachment spouts 11 are located in the closed position opposite the attachment spouts 11.
  • the end bar 28B located at proximity of the lateral face 7 of the frame 1, rests, in the closed position, by its ends on the flat upper surface of the support pads 16 of the frame 1 and has, in its central region and preferably centered, a bar 32 of general rectangular shape, parallel to the axis YY, projecting downwards from the grid 2, substantially perpendicular to the plane of the latter.
  • this bar 32 When the grid 2 rests on the frame 1, this bar 32 is positioned, in a centered manner, opposite the longitudinal end most internal to the frame 1 of the elastic member 26, its longitudinal dimension being less than the distance separating the two protuberances 20A and 20B, and its lower face 32A lying above the upper face of the lip 24 of the protuberance 23.
  • the ends of the bar 28B project, parallel to the axis XX, towards the outside of the grid 2, each of the two external faces of the said bar 28B, parallel to the axis XX, comprising a cylindrical pivot 33A, respectively 33B, projecting towards the outside of the grid, parallel to the axis YY.
  • pivots 33A and 33B are coaxial, of different length, the pivot 33A being shorter than the pivot 33B, and are intended, when mounting the grid 2 on the frame 1, to be housed respectively in the openings 9A and 9B formed in the respective widenings 8A and 8B of the frame 1, thus allowing the articulation of the grid 2 relative to the frame 1;
  • the length of the pivot 33B is such that when the latter is fully inserted into the opening 9B, the pivot 33A is located outside the opening 9A, and the diameter of these pivots 33A, 33B is such that these can undergo horizontal and vertical translational movements in the substantially oblong, respectively horizontal and vertical portions, of the respective openings 9A and 9B intended to receive them.
  • the end being in the closed position of the grid 2 near the lateral face 6 of the frame 1 also extends in its part furthest from the lateral face 7 by a protrusion 34 directed towards the outside of the grid 2, parallel to the axis YY, which, in the closed position, is located opposite the internal face of the skirt 3, thus avoiding any possibility of accidental dislodging of the pivot 33A; this prominence 34 defines with the external cylindrical surface of the pivot 33B a free space 35 in which can be accommodated the upper wall, of thickness E, of the widening 8B.
  • the pivot 33B is introduced fully into the opening 9B, the latter being positioned in the upper part of the vertical oblong portion opening 9B.
  • the pivot 33A is then located opposite the upper part of the oblong vertical portion of the opening 9A, that is to say, considering FIG. 4, opposite the upper left space of the opening 9A, the protrusion 34 then being located above the enlargement 8B, the thickness E of the upper wall of which is housed in the free space 35 between the pivot 33B and the prominence 34.
  • the grid 2 is thus in the open position, articulated relative to the frame 1 by means of the pivots 33A and 33B which constitute its axis of rotation.
  • the locking of the grid 2 on its support frame consists firstly in lowering the latter, from the open position, by pivoting about its axis of rotation, and this until bringing the rounded surface 31C of the bead 31 of the fingers 30 in contact with the upper ramp 11A of the attachment nozzles 11 of the frame 1, the bar 32 then being located opposite the elastic member 26.
  • the prominence 34 allows on the one hand to guide the grid 2 when it is positioned in the frame, preventing in particular any movement of the latter parallel to its axis of articulation. , and on the other hand allows, by its centering action, to properly hold the bar 32 facing the elastic member 26.
  • the bead 31, by progressive decompression of the elastic member 26, slides along the lower ramp 11B of the hooking nozzles 11, and this until bringing the ramp 31A of the fingers 30 in contact with said lower ramp 11B, thus obtaining a snapped-in position of fingers 30 with the hooking spouts 11 which corresponds to the final locked position.
  • the pivots 33A and 33B move, by translation parallel to the plane of the frame 1, in the opposite direction to that described in the previous compression step.
  • the bar 32 bears on the elastic member 26 and thus maintains the latter under slight compression.
  • This prestressing of the elastic member 26 makes it possible to absorb and absorb any movement of the grid 2 in the rebate of the frame 1, in particular during the passage of rolling loads, and consequently avoids clicking or flapping noises which can result.
  • attachment ramps 11B and 31A can be replaced by horizontal surfaces.
  • the embodiment which has just been described relates to an articulated grid, but it is however possible to envisage a solution where a plane or concave grid, or a cover plate, rests in a non-articulated manner on a support frame.
  • the pivots 33A, 33B can, for example, be replaced by a snap-fastening system of the type comprising fingers secured to the grid or plate, intended to snap in by cooperation with hooking spouts secured to the skirt of the frame, at least one elastic member, positioned in a housing of said frame provided for this purpose, offering advantages identical to those mentioned above.
