- An embodiment of the cover according to the invention schematically shown in the fig. 1 through 3, comprises a
rectangular frame 1, withrectangular opening 2 and arectangular lid 3, both parts usually from cast iron. Thelid 3 of the invented cover does not completely cover the frame, but leaves an opening at the one (front) end, which opening can be masked by means of a beam-like filling piece 4, from a heard wear-resistent material, for instance ebonite. - To facilitate the insertion of the
filling piece 4 into the frame or the removal therefrom respectively, said filling piece is provided at the ends with an through opening 5, for receiving a not-shown insertion tool. - On the horizontal support face of the
frame 1, generally indicated with 6, the seat, generally indicated with 7, from hard rubber, with substantially rectangular cross section is not circum-; ferentially arranged; at a short rectangular side (rear side) of the frame aseat portion 7a is provided, on theportion 6a of the support face, and at both ends connected thereto,seat portions 7c and 7d respectively are provided extending partially on thesupport face portion 6c and 6d respectively, over a long rectangular side of the frame. - The seat 7 abutting the
enclosure face 8 extending upwardly with respect to thehorizontal support face 6 of the frame comprisescams 10 extending alternately inwardly with respect to theenclosure face 9 extending upwardly with respect to the support face'6 and outwardly extendingrecesses 11, at the location of which recesses, the thickness of the seat 7 is smaller than that of the cams to form a radial water discharge channel 7A at the upper surface (vide fig. 4). - The
lid 3 comprises a support face, generally indicated with 12, which comprises only three support face portions just as thesupport face 6 of theframe 1, namely asupport face portion 12a, at the short reactangular side of the lid and asupport face portion support face portion 12 comprising anenclosure face 13 extending upwardly with respect thereto and anenclosure face 14 extending downwardly. - The
enclosure face 14 extending downwardly with respect to thesupport face 12 of the lid comprises mutually spaced outwardly directedcams 15. The longitudinal size of the support face portion, indicated with 16, is somewhat greater than the corresponding longitudinal size of acam 15 for insertion and removal respectively of the lid. - In order to insert the
cover 3, this should be moved downwardly into theframe opening 2 with theend face 18, forming the restriction of bothend cams 15 at the long rectangular sides of the lid, at the rectangular side (front side) of theframe 1, where the freesupport face portions 6c, 6b and 6d of the frame are situated, thecams 15 at the downwardly directedenclosure face 14 of the lid being able to move downwardly between therecesses 11 of the seat 7 at the support face of theframe 1, until the lid with thesupport face 12 rests on the upper surface of theseat cams 10, after which the lid is shifted over the longitudinal size of theend cams 10 at theseat portions 7c, 7d in the direction of the other rectangular side and therewith, on theseat portion 7a at thesupport face 6a of theframe 1. - The
cover 3 leaves then a portion of the frame opening 2 at the first-mentioned rectangular side (front side) of theframe 1, where the free support faces 6c, 6b, 6d are situated, said portion can be masked by means of thefilling piece 4. The size of thelower surface 19 of thefilling piece 4 can be such that this can cover said free portions of thesupport face 6 of theframe 1, in which the filling piece with the end faces 20, 21 and theside face enclosure face 8 of the frame, and gthe confrontingend face 18 of thelid 3 respectively. - As, as is explained above, the
cams 15 at the downwardly directedenclosure face 14 of the lid, when positioning this on the seat 7 of theframe 1, should be able to pass along the inwardly extendingrecess 11 at the seat, after which the lid with thesupport face 12 is displaced slidingly over the upper surface of thecams 10 of the seat, over the longitudinal size with acam 10 to the other rectangular side of the frame opening 2 to have thecams 15 thereof engage beneath thecams 10 of the seat with the edge for "guarantying" the cover, theseat portions 7c and 7d of the frame comprise, at the free end thereof, preferably acam 10 and the corresponding portions of the downwardly extending enclosure face of the lid, at the free end thereof, also acam 15, in which the lenth of theseat portion 7c, 7d is the same as the corresponding length of the long rectangular side of theenclosure face 14. - In order to cover afterwards the free
support face portions 6c, 6b and 6d at the frame opening, the rectangular lower surface of thefilling piece 4 can comprise a long rectangular side, equal to the inner size of thesupport face 6 of the frame a and a short rectangular side, somewhat greater than the longitudinal size of one seat cam and the "free"support face portion 6c(6d) of theframe 1.. - In fig. 4 on the basis of a cross section IV and V, along a face B of the
frame 1 and a cross section V-V, along a face C of the lid, the situation is indicated, in which the lid can be lifted; from the frame, or can be positioned in the frame. In fig. 5 on the basis of a cross section V-V, along a face C of the lid and the frame the situation is indicated, in which the lid is secured after: shifting over the longitudinal size of a seat cam. - In fig. 5 the
cams 15 at the downwardly extendingenclosure face 14 of thelid 3 are situated just opposite thecams 10 at the seat 7 of theframe 1. The faces C of lid and frame coincide. - In fig. 4 the cams at the downwardly directed
enclosure face 14 of the lid are situated just opposite therecesses 11 of the seat 7 at theframe 1, when the lid is for instance moved forwardly over a cam width and the face C of the lid coincides with the face B of the frame. - It is remarked, that in fig. la an angle portion A of the
frame 1 of fig 1 is shown on larger scale, to indicate, that there an enlarged, Z-shaped cam 15A (vide fig. 2) extends outwardly with respect to theenclosure face 14 extending downwardly with respect to the lid to engage beneath thecam 10 of theseat portion 7a and of theseat portion 7d of theframe 1 extending inwardly at that location. Thecams 15 at theenclosure face 14 at this short rectangular side of the lid do not slide in longitudinal direction, but in transverse direction thereof beneath thecams 10 at theseat portion 7a. - In the fig. 6, 7 and 8 resp. the frame, the lid and the filling piece respectively generally indicated with 24, 25 and 26 resp. of a second embodiment of the invented cover are shown, in which the seat generally indicated with 27 is not attached to the frame, as in above-described embodiment, but to the
lid 25. - As is shown in fig. 6 the horizontal support face, generally indicated with 28, is provided circumferentially on the
frame 24 and it comprises a downwardly directedperipheral edge 29 surrounding theopening 33 of the frame. Theenclosure face 30 of the frame extending upwardly with respect to thehorizontal support face 28 comprises mutually spacedcams 31 extending inwardly with respect to said enclosure face (vide also fig. 10 and 9 resp.), said cams being mounted on both long rectangular sides of the opening 33 of theframe 24 and one short rectangular side of the edge opening 33. I - As is shown in fig. 7 outwardly extending
cams 36 and inwardly extending recesses 37 (dottedly indicated in fig. 10) are provided on theseat 27 which is mounted here around thesupport face 34 of the lid 25'(vide also fig. 9 and 10) with respect to theenclosure face 35 extending upwardly with respect to thehorizontal support face 34 at the location where the thickness of theseat 27 is smaller to form a radial channel 27A at the lower surface for letting the rain water pass. - To cover the opening 33 of the frame 24 (vide fig. 6) the
lid 25 should first be positioned in the vicinity of the rear side of the frame on thesupport face 28 thereof, in which theseat cams 36 at thelid 25 can freely pass downwardly along the upwardly extendingenclosure face 30 of the frame, after which the lid, to be able to "guaranty" this with respect to the france 24, is moved forwardly over the longitudinal size of acam 31 extending inwardly with respect to the enclosure face with theseat 27 sliding over thehorizontal support face 28 at the long rectangular sides of the' frame and then theseat cams 36 engage beneath thecams 31 at the upwardly extendingenclosure face 30 of the frame. Therewith theseat cams 36 move at the facing short rectangular side of the lid in transverse direction with respect to thecams 31 of the frame. - The remaining portion of the frame opening, at the location of the
portions 28a (at the complete short rectangular side of the frame 24) and 28c, 28d (at the rear end of both the long rectangular sides of thesupport face 28 of the frame) can be masked by means of afilling piece 26. - The
lower surface 38 of the filling piece can have a longitudinal size, practically equal to the inner size of theframe 24 at thesupport face portion 28a, and a transverse size, somewhat greater than that of acam 31 and the freesupport face portion 28c(28d) of theframe 24. The end surfaces 39, 40 and the side surfaces 41, 42 of the filling piece can be adapted to the sizes of the frame. Thelongitudinal side surface 42 preferably supports with a certain pressure against theseat cams 36 at the confronting side face of the upwardly directedenclosure face 35 of the lid. The advantage thereof is, that rattling of the filling piece in theframe 24 is counteracted. - Fig. 9 shows a cross-section IX-IX along the face B of the
frame 24 and a cross section X-X along the face C of thelid 25, in which the lid can be lifted from the frame or can be positioned in the frame. - Fig. 10 shows a cross section X-X along a face C of lid and frame to show the situation in which the lid, is secured after displacement over the longitudinal size of a
seat cam 36. - In fig. 10 the
seat cams 36 projecting outwardly with respect to theenclosure face 35 extending upwardly with respect to thehorizontal support face 34 of thelid 25 are situated just beneath thecams 31 at the upwardly extendingenclosure face 30 of theframe 24, the faces C of the frame and lid coincide in that case (guarantied position). - In fig. 9 the
seat cams 36 extending outwardly with respect to the upwardly extendingenclosure face 35 of thelid 25 are situated just opposite a portion of theenclosure face 30 extending upwardly with respect to thehorizontal support face 28 of theframe 24. Thelid 25 is in the position for removal in that case. - In the fig.11, lla, 12, 12a and 13 a third embodiment of the cover according to the invention is shown, in which the rectangular frame generally indicated with 42 is covered by a lid generally indicated with 43 comprising various
identical lid portions - The
frame opening 44 is, for enclosing the lid portions in theframe 42, furthermore masked at both ends by a fillingpiece - The embodiment of a lid portion, for
instance 43a appears more clearly from fig. 12a, indicating thelid portions - As in the
lid 25 of fig. 7 in the earlier described second embodiment of the cover, the seat, generally indicated with 46 (vide fig. 12a) is mounted circumferentially extending at thesupport face 47 of the lid portion.(forinstance 43b) and accordingly alternately provided withcams 48 extending outwardly with respect to the ¦ enclosure face extending upwardly with respect to the support.face 47 and radially extendingrecesses 49 and the seat is recessed in the shape of a gutter at the location of a-recess 49 for the removal of rain water. : - However, different from the
seat 27 according to fig. 7, in fig. 12a thecams 48b and thecams 48a respectively, of theseat 46 are somewhat shortened or enlarged at the transverse sides of thelid portions cams 48a partially extends beneath thelid portion 43b, in that an additional "quaranty" is obtained at said transverse sides of the lid portions. - Both longitudinal sides of the frame 42 (fig. 11) are provided at the
enclosure face 51 extending upwardly with respect to thesupport face 50 with mutually spaced inwardly extendingcams 52, between thecam 52 at both ends of the longitudinal sides, in the vicinity of a transverse side of theframe 42 between saidcam 52 and theenclosure face 51 of said transverse side (vide also fig. 13) a space is provided for arranging the filling piece at said end of theframe 42, in this case the fillingpiece 45a. The upwardly extending enclosure face 51a at that transverse side of theframe 42, is provided with an inwardly extending cam 52a extending over the complete size of the transverse side, beneath which an outwardly extending cam extending over the complete size of the fillingpiece 45a can engage, when this filling piece is positioned in theframe 42. The same is in force for theother filling piece 45b. - After for instance first the filling
piece 45a being mounted at its location in theframe 42, thefirst lid portion 43a can be positioned in the frame,in which theend cam 48 of theseat 46 at that lid portion (vide fig. 12a) can pass via the portion of theenclosure face 51 behind saidend cam 52, after which thelid portion 43a can be moved toward the transverse side of the frame. According to fig. 13,.showing this situation "schematically", at the facing transverse side of thelid portion 43a on the contrary (shorter)cams 48b are provided at theseat 46 of the lid portion (which cannot cooperate with an adjacent lid portion by an guarantying action). The fillingpiece 45a moreover comprises at the facing transverse side arecess 54. The recess formed by theshorter cam 48b of theseat 16 on thelid portion 43a is schematically shown (fig. 13). - Thereafter the
lid portions 43b etc can be subsequently inserted, after insertion of thelast lid portion 43n, the fillingpiece 45b can be snapped at its location, in which it snaps with thecam 53 beneath the cam 52a of the other transverse side of theframe 42. Thelid portion 43n is also guarantied at the transverse side thereof, by means of further outwardly extendingcams 48a at theseat 46 thereof. - The
lid portions 43 as well as the fillingpieces 45 can be exchanged. - Finally there is also an other embodiment, according to fig. 14, 14a and 14b, for a lid portion of the above described frame of fig. 12 and 13.
- There the
lid portion 60 only comprises at the longitudinal edges a beam-shapedseat 61 with outwardly extendingcams 62; at the transverse sides only mutually spaced recesses are provided at the upwardly extending enclosure face.
