Definitions

  • This invention relates to cover and frame assembly and more particularly but not exclusively to a cover and frame assembly being so called roadway furniture, which is adapted to close an access opening in a pavement, roadway or other ground surface, such as a manhole or pit in the ground.
  • the cover may comprise a solid cover or may be a grating being a cover with openings provided therein for the drainage of water.
  • the frame comprises a pair of end frame members and a pair of side frame members which together provide an opening
  • the side frame members each comprising an inwardly extending formation which provides an upwardly presented running surface which extends between the end frame members and includes a surface part providing a recess in the running surface
  • the cover having a pair of depending walls which in use extend alongside the side frame members and which each comprise an outwardly extending formation which provides a generally downwardly extending surface part which is received in a recess of a corresponding running surface of the adjacent side member when the cover is received in the frame, the arrangement being such that the cover may be raised at one end and moved across the opening such that the downwardly extending surface parts of the cover ride up the respective surface parts of the recesses of the side frame members and slide along the respective running surfaces of the side frame members.
  • the invention has particularly, but not exclusively been developed for high load applications, such as airfields.
  • the end frame members 14 and 15 each comprise three end frame elements 18, 19 and 20 which are connected together as hereinafter described so as to provide an end frame member 14, 15 of requisite length.
  • the end frame elements 18, 19, 20, are each of substantially identical configuration and dimension.
  • FIGS 2 a and 2 b there is shown a cover part 21 adapted to close one e.g. 16 a of the three opening areas 16 a 16 b and 16 c of the access opening 16.
  • Cover part 21 thus provides one cover part of a three part cover which completely closes the access opening 16.
  • Other cover parts to close opening areas 16 b and 16 c may be identical.
  • End frame element 19 is shown in isolation.
  • End frame element 19 comprises a pair of side flanges 25 one at each end of an end wall 26.
  • base flange 27 which is substantially perpendicular to the end wall 26.
  • Each of the side flanges 25 has provided therein a pair of openings 29 by means of which fasteners can be used to connect together end frame element 19 with adjacent end frame elements 18 and 20 to form an end frame member 14, 15.
  • a flange 30 Extending inwardly of the access opening 16, from the end wall 26 of each of the end frame elements 19, is a flange 30 which comprises in this example, a pair of seating formations 32 each comprising a pair of downwardly converging walls 32 a , 32 b which formations 32 each receive a seating 75 provided on one of the cover parts 21, as hereinafter described.
  • the flange 30 also provides a pair of parts 35 of seating formations, one at each end of the end frame element 19.
  • the seating formations 35 a formed by the parts 35 also each comprise a pair of converging walls 36 and 37 which are adapted to receive seatings 40 provided on the extreme ends of dividing members 17 a , 17 b .
  • the dividing members 17 a , 17 b each have seatings 40 (see figures 5 to 5 c ) of corresponding configuration to the complete seating formations 35 a formed by the parts 35 provided by adjacent end frame elements 18-20.
  • the dividing members 17 a and 17 b can removably be connected in the frame 11 so as to extend between the end frame members 14,15, as shown in figure 1 to divide the access opening 16 into the three opening areas 16 a , 16 b ,16 c .
  • Each dividing member 17 a , 17 b comprises a pair of surfaces 41,42, either side of an upstanding rib 43, which surfaces 41 and 42 extend for substantially the full length of the dividing member 17 a , 17 b , between the end frame elements 18 to 20 beneath respective cover parts 21 which may or may not seat on the surfaces 41,42.
  • Each running surface 44 a includes a recess 46 a provided by a curved surface part 46 for a purpose hereinafter explained.
  • the main side frame members 12 and 13 are shown in figures 4 a to 4 d and each comprise a side wall 50 having at a base thereof, a flange 51 to give the main side frame members 12,13, rigidity.
  • the main side frame members 12,13 each comprise a pair of openings 52 corresponding in position to the openings 29 provided in the side flanges 25 of the end frame elements 18-20.
  • the openings 52 are provided in a flange 53 which is a continuation of the side wall 50.
  • each running surface 56 a includes a recess 57 a provided by a curved surface part 57 substantially identical in configuration to the curved surface parts 46 provided on the dividing members 17 a and 17 b .
  • the main side frame members 12 and 13 include triangular fillet strengthening ribs 60 towards either end of the end frame member 12,13, again for rigidity.
  • a cover part 21 comprising in this example, a generally solid cover part top surface 70 from which depend a pair of parallel cover part walls 71.
  • the walls 71 in this example extend for substantially the full length of the cover part 21 between the end frame members 14 and 15 and add significant rigidity to the top cover part surface 70.
  • each of the walls 71 Extending outwardly from each of the walls 71, there are provided a pair of outwardly extending formations 72 which each includes a curved surface part 72 a corresponding in position and to the configurations of the curved surfaces 46 and 57 of the dividing members 17 a , 17 b and the main side frame members 12 and 13 respectively.
  • a pair of seatings 75 which each comprise a pair of downwardly converging walls 75 a , 75 b which are adapted to seat in corresponding seating formations 32 of the respective end frame member elements 18,19 or 20.
  • top cover part surface 70 extends both outwardly sideways beyond the curved surface seatings 72, and beyond the seatings 75 at the end of the cover part 21 and that the thickness t of the top cover surface part 70, corresponds generally to the height of the step between formations 55 which extend beneath the edges of the cover part 21 and the top surfaces of the main side frame members 12 and 13, which is also substantially the distance between the top surface of upstanding rib 43 and the surfaces 41 of the dividing members 17 a , 17 b which extend beneath the edges of the inner part and the step between the top of the end frame elements 18 to 20 and surfaces 38 provided thereon which also extend beneath the edges of the cover part 21.
  • the cover part 21 may be received into any of the opening areas 16 a , 16 b , 16 c of the access opening 16 substantially to close the respective opening area, with the outwardly extending formations 72 of the cover part 21 received in recesses 46 and 57 as appropriate, and the seatings 75 received in seat formations 32 of the respective end frame elements 18-20.
  • the curved surface parts 72 a of the cover part 21 are maintained out of engagement with the respective curved parts 46,57 of the recesses 46 a , 57 a , but the curved surfaces come into engagement as the cover part 21 is slid from the frame 11 as hereinafter described.
  • a groove 80 which thus extends around substantially the entire periphery of the underside of the cover part 21.
  • the groove 80 may be provided with a suitable sealing member such as a neoprene seal or alternatively sealing between the cover part 21 and the formations 55, and surfaces 41 and 38 of the frame 11 may be achieved by some other means.
  • cover part 21 may be bolted down relative to the frame 11 by means of inter-engaging fastening means, but generally, particularly where the cover part 21 is heavy, the weight of the cover part 21 will be sufficient to maintain it in position, and sufficiently to compress a sealing member in groove 80 when provided.
  • the cover part 21 When it is desired to remove the cover part 21 from the frame 11, the cover part 21 is raised at one end. To achieve this, if desired a prising tool may be inserted between the cover top part surface 70 and an end wall 26 of an appropriate end frame element 18-20.
  • the cover part 21 As the cover part 21 is raised at one end, and moved across the respective opening area 16 a , 16 b , 16 c , e.g. by pulling, the curved surface parts 72 a of the outwardly extending formations 72 of the cover part 21 will be brought into engagement with corresponding curved surface parts 46 a , 57 a of the recesses 46 and 57 provided respectively by the adjacent dividing member 17 a , 17 b and main side frame member 12,13.
  • the outwardly extending formations 72 of the cover part 21 will ride up the respective recesses 46,57 and run along the respective running surfaces 44 a , 55 a provided by the respective inwardly extending formations 44 and 56 to facilitate removal of the cover part 21 from the frame by sliding.
  • cover parts 21 are required completely to close the access opening 16, but in another example where dividing members 17 a , 17 b are not provided the cover may be provided by a single cover part to close access opening 16. Where the frame 11 is longer than that shown, and comprising more than three modular end frame elements 18-20, more than three cover parts 21 may be provided completely to close the access opening 16.
  • the frame may comprise no dividing members, or one or more than two dividing members to divide the access opening 16 into individual opening areas 16 a to 16 c .
  • a single cover part 21 may comprise the cover and that outwardly extending formations of the cover may co-operate with corresponding recesses of the two opposite main side members 12 and 13.
  • each such dividing member may in effect provide a side frame member for each of a pair of cover parts such as cover parts 21, located in opening areas to either side of the dividing member.
  • the fasteners which interconnect the end frame elements 18-20 and the main side members 12,13, to the respective end frame elements 18,20 are bolts
  • other kinds of fasteners which interconnect the end frame elements 18-20 together and with respective side frame members 12-13 may be provided or other fastening means altogether.
  • at least the side frame members 12-13 may have integral threaded studs adapted to co-operate with the first 18 or second 20 in the line of the end frame elements 18-20.
  • each of the dividing members 17 a and 17 b need not be of the configuration described, although preferably seatings 40 such as those described are provided to enable the dividing elements 17 a and 17 b removably to be attached to the end frame members 14,15 of the frame 11 to provide a substantially rock free seating for the dividing members 17 a and 17 b in the frame 11.
  • end frame members 14,15 need not be modular as described.
