  • Each stamp consists of a plate rectangular metal, for example galvanized steel, stainless steel or aluminum.
  • the device shutter of an opening (not shown), such that a floor look, includes a rectangular frame 1 bordering the opening and whose sides present in cross-section an L shape thus defining horizontal fins 2 and vertical fins 3, the horizontal fins 2 defining themselves a rectangular access opening to the underlying gaze.
  • This device also comprises in the present case three removable pads 4 closing the frame 1 arranged side by side at their closed position of this frame and resting on it.
  • the buffers 4 each consist of a plate rectangular metal, for example galvanized steel, stainless steel or aluminum, the plates of these buffers being arranged in the same horizontal plane at their closing position of the frame 1 while being in outcrop with the upper edges of the fins vertical 3 of this frame. At this closing position, games remain between the edges on the one hand from each other adjacent buffers 4 and other between the peripheral edges of these buffers and the vertical fins 3 of the frame 1.
  • Each extreme buffer 4 rests on the fins horizontal 2 of frame 1 through three four vertical walls 5 integral with the face buffer 4 thereby forming a frame.
  • the central buffer 4 rests on two fins opposite horizontals 2 respectively by two walls opposite verticals 5 of four vertical walls 5 integral with the inner face of this stamp for also form a frame, the other two walls 5 being opposite walls 5 of the two adjacent extreme buffers 4.
  • Each buffer 4 is attached to frame 1 by at least two bolts 6 opposite one another being arranged on either side of the longitudinal axis of the frame 1 parallel to the fins 3 defining the length of this frame.
  • Each bolt 6 has its threaded rod 6a through the corresponding horizontal fin and its nut tightening 6b bears on the underside corresponding to the horizontal fin 2, while the 6c head of this bolt is embedded in a stamp 4 counterbore defined by a piece 7 fixed under the buffer 4 while being crossed by the unthreaded part of the rod 6, as this is more apparent from Figure 2.
  • the device shutter is provided with means ensuring the tightness to the water of frame 1 and buffers 4 with respect to the opening defined by the horizontal fins 2 for prevent him from entering the opening of the gaze.
  • sealing means comprise first of all a sealing peripheral seal 8 made of a material elastomer arranged on the horizontal fins 2 of the frame 1 near the vertical fins 3 of this frame.
  • the sealing gasket 8 present in section transverse a rectangular shape with one of the edges is practically in support along the inner faces of vertical fins 3 of frame 1 and has a width less than the width of the horizontal fins 2.
  • the peripheral seal 8 is fixed by gluing on the fins 2, but it can be fixed by any other appropriate means, for example by partial embedding in a conjugate groove formed in the fins 2 or by screwing to these fins.
  • the seal device 8 can present in cross-section a square or circular shape.
  • each buffer 4 others that those facing each other have their lower ends held in prestressed support on the peripheral seal 8 under the action of the force of fastening bolts 6 so as to ensure a watertightness between these walls 5 and the fins horizontal 2 of the frame 1.
  • Each of the vertical walls 5 of a buffer 4 in support on the joint 8 has in cross-section a inverted T shape with transverse branch lower 5a bears on the peripheral seal 8 on almost the entire width of it.
  • the watertight means include also a cylindrical seal 9 made in an elastomeric material, integral with one of the walls vertical lines 5 of one of the buffers 4 located next to the vertical wall 5 of the adjacent buffer 4, these two walls verticals facing each other extending transversely to the vertical fins 3 constituting the longitudinal sides of frame 1, the cylindrical joint 9 extending the full length of the vertical wall 5 to which it is attached parallel to the edge longitudinal buffer 4 below this edge.
  • the central buffer 4 comprises at each of its opposed parallel vertical walls 5 respectively two cylindrical joints 9, each in prestressed support radially on the vertical wall 5 facing it adjacent buffer 4.
  • Each cylindrical joint 9 is made in one piece with a plate of elastomeric material 10 way that this set presents in cross section approximately the shape of a musical note.
  • the cylindrical seal 9 thus formed is attached to the wall corresponding vertical 5 of buffer 4 by a bar 11 flat metal screwed to the wall 5 so as to enclose the plate 10 of the gasket 9 between the vertical wall 5 and the flat bar 11.
  • the seal 9 could be fixed by any other appropriate means, for example by gluing the gasket plate 10 to the corresponding vertical wall 5 buffer 4 or by embedding the plate 10 in a conjugated groove formed in the vertical wall 5.
  • the vertical wall 5 of the buffer 4 situated opposite of the cylindrical seal 5 at its lower end beveled all along it as indicated in 5b at FIG. 5 so as to facilitate the assembly of these pads in frame 1 without damaging the cylindrical seal 9 and to prestress or compress radially the latter in the direction indicated by the arrow F in FIG. to ensure a perfectly tight contact between the gasket 9 and the vertical wall facing it 5 everything along this one.
  • cylindrical seal 9 has its face 9a which is flat and overflowing slightly in below the lower end 5c of the flat wall 5 to which is attached the seal 9 as is apparent from Figures 3 and 5.
  • the cylindrical seal 9 has its lower faces flat ends held in prestressed support by the fixing bolts 6 of the pads 4 respectively on two blocks 12 forming gaskets of material elastomer fixed, for example by gluing, on the opposite horizontal fins 2 of the frame 1 so conjoined juxtaposed with portions of edge of the peripheral seal 8 opposed to the vertical fins 3.
  • the sealing block 12 is square or rectangular shape with cross section rectangular or square of the same thickness as the attached 8 so as to be at the same level as this latest. Of course, block 12 can also be achieved by having a circular cross section if the peripheral seal 8 is also.
  • three buffers 4 so four blocks 12 are planned two to two opposites on which the faces are supported lower ends of two cylindrical seals 9 integral respectively opposite walls 5 of the buffer central 4. Each seal 12 is thus in line with the junction of the edges facing each other of two adjacent buffer plates.
