Definitions

  • the invention relates to a cover comprising a cap and a rim.
  • a cover for instance in an inspection or water discharge well, is usually applied in the surface of a road or footpath.
  • the grid cap of the cover can, as usually at one side, be provided with pivots or one or various stay cams, whereas the cap of the cover, at one side and the peripheral portion respectively, can be provided with one or various stay cams, in order to swing the grid cap or the cap open by means of a simple tool at the opposite side, or to remove same, which is necessary for cleaning the well with regular intervals.
  • the cap according to the invention comprises at least one slot-like opening extending from the periphery such that when applying an external force to a peripheral portion of the one cap portion, a resilient movement of the one cap portion with respect to the other one occurs in the plane of the cover.
  • the material is missing at one side of the grid cap at one or various ends of the slots.
  • the material is missing at two or various slots alternately at the end at one side or at the end at the opposite side of the grid.
  • the material of the cap is locally missing, seen in one direction extending from one side up to in the vicinity of the other side, or from the periphery up to in the vicinity of the periphery, under the formation of one or various slots.
  • the slot or slots obtained by the local failure of material enables or enable such a resilient movement in the plane of the cap or grid cap and rim, between the cap or grid cap portions perpendicularly to the slot-like opening or openings, that in a further embodiment of the cover according to the invention, in which the grid cap or the cap, at the side facing away from the stay cam or stay cams, or pivot shafts, is provided with a safety or locking cam or cams engaging beneath the adjacent side of the rim and with a locking recess. The safety or locking cam or cams can be released for the earlier mentioned cleaning purposes.
  • the grid cap or the cap consists of a suitable material, as for instance cast iron with nodular graphite or steel. Both the materials provide the necessary resilience to the cap or the grid cap portions for releasing the safety or locking cam.
  • a cover according to the invention is shown, provided with an inlet grid, generally indicated with 1 and a rim, generally indicated with 2, of rectangular embodiment, for instance for a discharge well to be mounted at the side of the road.
  • the grid 1 comprises a number of equal grid bars 3, with substantially rectangular cross section extending downwardly in flange shape increasing to the centre (vide fig. 3), whereas both the outermost grid bars 4 (vide fig. 2) and 5a, 5b respectively (vide fig. 1,2 and 4) are somewhat different, in relation to the support thereof.
  • the grid bars usually rest at their ends with a frame 6 interconnecting said bars (vide fig. 2 and 3) on the support face 8 extending inwardly from the enclosure face 7 (vide fig. 2-4) of the rim 2.
  • the grid bar 4 at the one end of the grid (vide fig. 2) is substantially beam-like and supports over the complete length thereof on the support face, at this side of the rim 2.
  • the grid 1 is represented in the same figure of the drawing, with two various embodiments.
  • the grid 1, in the one embodiment, can pivotably be secured at the other end around a horizontal shaft 9 (vide fig. 1, 2, 5) to the rim 2, by means of two shaft pins 10 secured to the bar 5a of the grid end (one of which is shown), which are supported in such a broad bore 11 (vide fig. 1 and 5) of the rim, that the grid bar 5a, which is substantially beam-like at the central portion in cross section, with rounded lower side 12, with the ends thereof merging into the frame 6, can rest on the support face 8 of the rim 2.
  • the grid 1 rests in the closed position at three sides thereof on the support face 8 of the rim.
  • the grid can also removably be embodied, in which case the grid bar 5b at said end of the grid 1 is provided with two laterally extending stay cams 13, only one of which being shown, which engage in a broad opposite recess 14 (vide also fig. 4) of the rim 2.
  • the grid bar 5b can advantageously be beam-like over the entire length in cross section, with flat lower side 15, with which the bar 5b is supported on the support face of sasid portion of the rim 2.
  • the grid is then circumferentially supported on the support face 8 of the rim.
  • the bar 4 is, at the other end of the grid at the central portion, provided with a laterally extending locking or safety cam 16, engaging in a recess 17 of the rim 2, so that the grid can support on the support face 8 of the rim without being hindered.
  • the grid according to the invention is resiliently embodied in the plane thereof, in the direction perpendicularly to the grid bar 5a with the pivot pins 10 or perpendicularly to the grid bar 5b with the stay cams 13, seen in the plane of the grid and in the direction perpendicularly to the other end bar 5a or 5b.
  • the material at the frame 6 of the grid 1 (vide especially fig. 1 and also fig. 2-4) is missing at one end of the slots 18 between the adjacent grid bars 3 at the central portion, and between the one end grid bar 4 and the adjacent grid bar 3, and between the other end grid bar 5a or 5b and the adjacent grid bar 3, alternately, so that the grid has a "sinus"- like configuration in plan view and alternately the support face of the rim between the ends of adjacent grid bars can be seen from above.
  • a locking recess 19 is mounted at the end grid bar 4, so that by means of a locking bar (not shown) provided with a fitting insertion end, to be mounted between the rim 2 and the locking recess 19, by swinging movement of the locking bar in the vertical longitudinal central face under reflecting action of the grid 1, the locking or safety cam 16 can simply be brought backwards and out of engagement with the locking recess 17, after which the grid can be rotated upwardly around the shaft pins 10, or the grid with the stay cams 13 rotating at the end grid bar 5b, can be swinged upwardly in the recess 14 and can subsequently be removed. This may be necessary for cleaning purposes of the lower structure of the cover.
  • the invention furthermore comprises a second embodiment of the cover according to the invention shown in the fig. 6 and 7, which is provided with a cap, indicated with 20 and a rim, indicated with 21, for instance of a discharge well to be mounted in the surface of a footpath, at the side of a road.
  • the cap 20 is supported with the face 23 extending inwardly from the enclosure face 22 at the peripheral flange edge 24 on the support face 26 extending inwardly from the enclosure face 25 of the rim 21.
  • the cap 20 is usually provided with two stay cams 29, engaging beneath a cam 30 extending inwardly at said location from the support face 26 of the rim 21 at both sides.
  • the material of the .cap 20 is alternately missing from one cap side to the other one, extending up to in the vicinity of the peripheral edge 24 thereof (vide fig. 6), forming intersections 31, such that seen from above the cap has a "sinus"-like configuration, in which the support face 26 of the rim 21 can be seen each time alternately at opposite sides thereof, between adjacent cap strips 20a.
  • a prolongation 33 is mounted, with a locking recess 34.
  • the peripheral edge 24 thereof is provided with a recess 35 (vide also fig. 6) and a downwardly extending locking or safety cam is mounted to the cap 20, which in the closure position of the cap 20 can engage in the recess 34 of above-said prolongation.
  • the safety cam 36 can be brought out of engagement with the locking recess 35 under spring action of the cap.
  • cast iron with lamellar graphite is not sufficiently resilient and on the other hand the local failure of material forms a weakening of the inlet grid 1, according to fig. 1, or the cap 20, according to fig. 6, for instance cast iron with nodular graphite or steel is applied for the grid or the cap.
  • cap of a cover according to the invention is schematically shown in fig. 8, which cap has a round configuration seen in plan view and indicated with 20b, which, at two locations at the periphery, is provided with a stay cam 29a and a safety cam 16a, with locking recess 19a and a slot 31a.
