Definitions

  • the invention relates generally to a device for closing an opening, comprising a frame and an articulated panel, of the type which constitute road equipment giving for example access to manholes buried in the ground.
  • the invention relates to a device for closing an opening, comprising a frame bordering the opening, a panel with one side substantially planar external, an internal face and a thickness, this panel being removable relative to the frame and rotatably mounted on the frame between a position opening in which it gives access to the opening, and a closed position in which it fits thick in a rim of the frame to apply on a frame rebate and seal the opening, and articulation members comprising at least one axis of articulation secured to an edge of articulation of the frame and having a flat in cross section, and an eye adjacent to a hinge edge of the panel, selectively engaged in the axis of articulation by reciprocal approximation of the panel in the open position and the frame, and leading to the thickness of the panel to through a reduced section guide not authorizing the engagement of the eye in the axis of articulation that at an angle of inclination of the panel relative to the frame included in a determined range of angles of inclination.
  • panels are designed to withstand loads important, especially when installed on the pavement and therefore they must resist the passage of motor vehicles, the panels therefore being at the both massive and relatively heavy.
  • the object of the present invention is to propose a shutter device with a removable panel articulated, whose installation is relatively easy despite the possibly heavy weight of the panel.
  • the device of the invention by elsewhere conforms to the generic definition given by it the preamble above, is essentially characterized in that the flat of the articulation axis has, by relative to the frame, an inclination greater than an angle right, and in that the determined range of angles tilt only includes tilt angles greater than a right angle, the panel cannot be mounted on the frame only in an inverted position.
  • the panel also comprises a ramp formed on its external face, adjacent to the edge of articulation of the panel, and having at least one connection surface inclined both relative to the external face and relative to the thickness of the panel, to guide the panel along the hinge edge of the framework for engaging the hinge pin in the reduced section guide.
  • the ramp forms an extra thickness on the face external of the panel.
  • the frame rebate present on the hinge edge of the frame, a first cam formed by a first elevation of the rebate, and that in its position opening, the panel is in abutment by a part relatively external of its thickness on the first cam, abutted by its external face on the edge of the frame, and in abutment by the eye or the section guide reduced against the hinge pin.
  • the panel has a bead on its hinge edge protrusion of a middle part of its thickness, that the first cam is terminated by a steep flank directed towards the rebate, let the heel run on the first cam when the panel moves from its closed position in its open position or vice versa, and that the heel falls from the first cam, abutted along the side abrupt, when the panel reaches its position opening, causing a lowering and blocking of the panel preventing any untimely closing.
  • a window is advantageously carved into the edge of the frame, on the edge of articulation of this frame, to allow the passage of the heel when rotating the panel between its position closing and its open position.
  • the frame rebate may also have, on the hinge edge of the frame, a second cam formed by a second elevation of the rebate, part relatively internal the thickness of the panel can thus walk on this second cam when the panel goes from its closed position to its position opening or vice versa, to move gradually the eye and the guide of reduced section with respect to the axis hinge.
  • the frame rebate may still show, on the hinge edge of the frame, a third cam formed by a third elevation of the rebate, the panel then presenting a foot which, at least in the panel closed position, relies on this third cam.
  • the articulation axis has for example a free end and a tied end, and the end tied is carried by a veil perpendicular to the edge and at the frame rebate and connecting them to each other.
  • the implementation of the device of the invention can be made easier by providing that the guide reduced section opens into a part of the eye which is furthest from the outside of the panel.
  • the invention relates to a device for closing an opening O ( Figure 2), and essentially comprising a frame 1 bordering the opening and a panel 2, removable relative to the frame 1 and selectively mounted thereon.
  • the panel 2 is mounted on the frame 1 rotating between an open position ( Figures 5 and 6) in which it gives access to opening O, and a closed position ( Figure 9) in which it closes the opening O.
  • This panel 2 which has ( Figure 2) a face outer 21 substantially planar, an inner face 22 and a thickness 23, applies, in its closed position, on a rebate 12 of frame 1 while registering, thickness, in a rim 11 of the latter.
  • the panel 2 is rotatably mounted on the frame 1 at means of articulation organs which comprise an axis articulation 31 secured to the frame 1, and an eye hinge 32, selectively engaged in the axis hinge 31 by reciprocal approximation of the panel 2 in open position and frame 1.
  • articulation organs which comprise an axis articulation 31 secured to the frame 1, and an eye hinge 32, selectively engaged in the axis hinge 31 by reciprocal approximation of the panel 2 in open position and frame 1.
  • the articulation axis 31 is in fact integral with a hinge edge 10 of frame 1, and has, in cross section, a flat 310.
  • the articulation eye 32 is adjacent to an edge hinge 20 of panel 2 and leads to the thickness 23 of the panel through a section guide reduced 320.
  • the function of the reduced section of guide 320 is to allow the engagement of eye 32 in the axis of articulation 31 that when the panel 2 presents by relative to frame 1 a tilt angle A (Figure 2) within a specified range A0-A1 of angles inclination, defined between a minimum angle A0 ( Figure 4) and a maximum angle A1 ( Figure 5).
  • the flat 310 of the axis of articulation 31 has, with respect to frame 1, a tilt J ( Figure 2) greater than a right angle, and the minimum angle A0 is greater than a right angle, the A0-A1 range of tilt angles allowing the engagement of the eye 32 in the axis of articulation 31 does not therefore understanding that tilt angles greater than A right angle.
  • the panel 2 cannot be mounted on the frame 1 only in an inverted position, that is to say a position in which its external face 21 is more oriented towards the plane of frame 1 than does is its internal face 22, the panel 2 thus being naturally stressed, by gravity, outside opening O and therefore not tending to close spontaneously.
  • panel 2 of the illustrated device comprises a ramp 4 forming a additional thickness on the external face 21 of the panel, adjacent at its hinge edge 20, and having a surface 40 which connects the surface without sharp angles external 21 of the panel 2 to the thickness 23 of the latter.
  • connection surface 40 of which the inclination advantageously changes so progressive, is in any case inclined at the same time by with respect to the external face 21 and with respect to the thickness 23 of the panel, to allow the mounting of panel 2 on frame 1, guide this panel along the edge hinge 10 of the frame until the axis 31 is engaged in the section guide reduced 320.
  • the rebate 12 of the frame has a first cam 5 which is formed by an elevation of the rebate 12, and which is used to block the panel 2.
  • the panel 2 in its open position, is in abutment at a point B1 by a relatively external part 231 of its thickness 23 on the first cam 5, in abutment in one point B2 by its external face 21 on the rim 11 of the frame, and in abutment at a point B3 by the eye hinge 32 or reduced section guide 320 against the hinge pin 31.
  • panel 2 has, on its edge articulation 20, a heel 230 which projects from a middle part of its thickness 23, and which is intended for cooperate with an abrupt side 51 of the cam 5, directed to rebate 12.
  • a window 110 ( Figures 1, 3, and 10) is hollowed out in the edge 11 of the frame 1, on the edge hinge 10 of this frame, to allow passage of the heel 230 during the rotation of the panel 2 between its closed position and its open position.
  • the rebate 12 of the frame also has a second cam 6, which is formed by a second elevation of the rebate, and which is used to guide a relatively internal 232 (figure 2) of the thickness 23 of the panel.
  • this part 232 travels on the second cam 6 when the panel 2 passes from its position closing to its open position or vice versa, the guidance provided by this cam 6 making it possible to move gradually eye 32 and the reduced section guide 320 with respect to the hinge pin 31.
  • the rebate 12 of the frame presents, on the hinge edge 10 of the frame, a third cam 7, which is formed by a third elevation of the rebate, and which, at least in the closed position of the panel 2, provides support for a leg 222 of the panel.
  • the hinge pin 31 does not need to be held at its two ends, but may on the contrary have a free end 311 and a linked end 312.
  • the linked end 312 of this axis can be carried by a veil 13 which is perpendicular to the edge 11 and the rebate 12 of the frame and which connects them to one another.
  • the reduced section guide 320 preferably opens out in a part of eye 32 which is furthest from the external face 21 of the panel 2.
  • the ramp 4 is placed on the upper part of the ledge 11 of frame 1.
  • panel 2 By the gradual decrease in the strength of restraint exercised by the operator, panel 2 overturns slightly and locks in its open position (figure 5).
