Definitions

  • This invention concerns a cover for drainage pits and the like, as set forth in the main claim.
  • the cover for drainage pits and the like is used advantageously in the field of paving and flooring so as to close a discharge hole positioned below the cover and possibly also to restrict the emerging of smells from water drainage and sewerage systems in general.
  • the cover for drainage pits according to the invention may be of a type with a packing to provide a hermetic seal and of a light or heavy type without packings.
  • the cover according to the invention may be made of galvanized steel or of brass or of another metallic material suitable for the purpose.
  • the cover according to the invention is advantageously, but not only, of the type disclosed in Italian patent IT-B-1.226.186 in the name of the present applicants.
  • the cover according to the invention may be of a type including an extractable central plug.
  • Covers have been disclosed which are employed in particular in the building field but which may also serve for the closure of cesspits and the like.
  • covers of the state of the art normally consist of a first stationary metallic containing frame with which a second removable metallic frame forming the framework of the cover cooperates.
  • This first stationary containing frame is secured to the ground or floor and is positioned at the same level as the ground or floor so as to form a continuous surface together with that ground or floor.
  • the second removable frame is generally filled with a pouring of cement, with washed gravel or with porphyry tiles or concrete blocks or other analogous materials.
  • covers of the state of the art generally include attachment holes positioned in at least two opposed sidewalls of the removable frame; appropriate hook-shaped means cooperate with these holes in the lifting and displacement and are often found to be not very practical nor easy to handle.
  • this hook-type system entails the problem that, as it requires an accessory separate from the cover, this accessory is not always supplied by the producer and has to be produced by the user as and when required.
  • a material suitable to form the accessory is often not available and the hook-shaped means have to be replaced by substitutes such as cables, bent iron rods and other substitutes, which may be the cause of accidents inasmuch as they are found unsuitable for the purpose.
  • the covers of the state of the art may include a central extractable plug, which acts as a grip for raising the second removable frame when it is necessary to have access to the zone below the cover.
  • the lifting of the second removable frame by means of the central plug meets with greater resistance on all its sidewalls owing to the effect of the friction between the sidewalls of the removable frame sliding against the sidewalls of the stationary frame and owing to the suction effect created by the fact that the removable frame is lifted while remaining substantially horizontal.
  • the cover for drainage pits and the like according to the invention is advantageously, but not only, of the type disclosed in patent IT-B-1.226.186 in the name of the present applicants.
  • the cover according to the invention may also include lifting plug means and also lateral holes for use in lifting with the help of the hook-shaped means already disclosed in the prior art.
  • the cover according to the invention comprises a first stationary metallic containing frame with which a second removable metallic frame forming the framework of the cover cooperates.
  • This second removable metallic frame comprises at least one engagement and lifting means of a handle type, which has a first inactive retracted position and a second engagement position, in which it protrudes upwards from the second removable frame.
  • the engagement and lifting means normally stays in the inactive position, in which it is positioned by gravity when it has been released by the operator.
  • the engagement and lifting handle means is brought back to its lowered inactive position by a light pressure applied by the operator.
  • This engagement and lifting handle means is lodged by sliding in a seating associated with the interior of the second removable metallic frame.
  • This seating is advantageously positioned in cooperation with one of the sidewalls of the second removable frame but is suitably separated from that sidewall so as to prevent the filling material entering the seating.
  • the cover according to the invention includes two engagement and lifting means positioned in opposed sidewalls of the second removable metallic frame acting as a cover so as to make possible the lifting and subsequent movement of that cover while keeping the cover always in a substantially horizontal position.
  • the engagement and lifting handle means may consist of a metallic or a plastic material, which is advantageously of a type resistant to chemical agents and/or weathering, which would impair a reasonably long working life.
  • engagement and lifting handle means may be conformed with a "D" shape or a "T" shape.
  • the handle means are of an articulated type and the seating is positioned in cooperation with one of the sidewalls and with the bottom of the second removable frame.
  • the engagement and lifting handle means includes advantageously attachment means of a claw-type, for instance, which enable the operator to engage the handle and to lift the handle so as to bring it from its inactive position to its engagement position.
  • the cover according to the invention includes both the engagement and lifting handle means and the central lifting plug.
  • the lateral lifting of the removable frame reduces considerably the resistance generated by the reciprocal friction between the respective sidewalls of the stationary and removable frames and also substantially eliminates wholly the suction effect.
  • the work to lift the removable frame requires less effort since this work can be carried out in two consecutive steps, namely a first partial lifting of the removable frame on one side and a simultaneous lateral sliding of that removable frame in such a way as to place the removable frame on the stationary frame, and a second final lifting of the removable frame by means of two engagement points.
  • These two engagement points may consist of two engagement and lifting handle means associated with two opposed sidewalls of the removable frame, or may consist of one engagement and lifting handle means and of the opposed sidewall itself.
  • the engagement and lifting handle means according to the invention may be used to carry out the sliding of the removable frame on the stationary frame until the latter has been fully uncovered.
  • the cover according to the invention thus makes possible the reduction of the possibility of accidents or distress for the operator during the operations of uncovering and covering the underlying drainage pit.
  • the reference number 10 in the attached figures denotes generally a cover for drainage pits according to the invention.
  • the cover 10 for drainage pits according to the invention is used in the building field to close drainage pits and the like in the ground.
  • These covers 10 for drainage pits consist of two frames, namely a first stationary frame 11 and a second removable frame 12 respectively.
  • the first stationary frame 11 in this case has a square shape and is fitted securely in the ground or flooring over the pit and consists of four L-shaped metallic elements 13 welded to each other.
  • the second removable frame 12 acts as a cover and cooperates with the inside of the first stationary frame 11.
  • the second removable frame 12 is formed as a container, that is to say, with a base 14 and with sidewalls 15, which are advantageously inclined at an angle to the vertical.
  • the frames 11 and 12 are normally made of metallic plate, which is galvanized and/or coated with a protective varnish resistant to weathering and chemical attack.
  • the second removable frame 12 comprises at least one engagement and lifting means 16 of a handle type 17 which is associated with a sidewall 15.
  • the engagement and lifting means 16 includes a containing seating 18 to permit sliding and also handle means 17.
  • the containing seating 18 to permit sliding is associated, by means of a screw 19 for instance, with the inner surface of the sidewall 15 and has the purpose of positioning within itself the handle means 17.
  • the handle means 17 have a first inactive retracted position 17a, in which they are wholly contained within the containing and sliding seating 18, and a second engagement position 17b, in which they protrude upwards from the containing and sliding seating 18 and therefore from the cover 10.
  • the handle means 17 are conformed as a " D ".
  • the handle means 17 are conformed as a " T ".
  • retaining means 26 included in the handle means 17 cooperate with mating travel-limiting means 25 located in the containing and sliding seating 18.
  • the handle means 17 may be made of a metal or of a plastic material resistant to chemical agents and weathering.
  • the containing and sliding seating 18 includes at its lower end discharge holes 24, through which are discharged the dust and dirt which may be introduced into the seating 18.
  • the upper part of the handle means 17 includes lateral claws 20, which cooperate with mating hollows 21 included in a coordinated position in the upper part of the containing and sliding seating 18.
  • the cover 10 includes two engagement and lifting means 16 of a handle type, which are associated respectively with two opposed sidewalls 15 of the second removable frame 12.
  • the base 14 of the second removable frame 12 forming the cover 10 according to the invention includes an aperture 22 with which a plug 23 cooperates.
  • the second removable frame 12 includes at least in one sidewall 15 two attachment holes with which the lateral claws 20 cooperate during the step of lifting the second removable frame 12.
  • the handle means 117 are of an articulated type.
  • the articulated handle means 117 comprise an upper element 27a and a lower element 27b joined together with an articulated joint 28.
  • the articulated joint 28 consists of an intermediate pivot 29 substantially positioned at a right angle to the direction of movement of the articulated handle means 117.
  • the articulated handle means 117 are replaced by a plurality of elements positioned in line and joined together, two by two, by a relative articulated joint.
  • the containing and sliding seating 118 extends partially in the sidewall 15 of the second removable frame 12 and partially in the base 14 of the second removable frame 12 without a break in continuity.
  • the articulated handle means 117 have a first retracted inactive position 117a (Fig.6a), in which the two respective upper 27a and lower 27b elements are positioned at an angle to each other, and a second engagement position 117b, in which the two respective upper 27a and lower 27b elements are aligned with each other.
