REFUSE HOLDER WHICH IS SUITABLE TO BE PLACED IN A PIT

Abstract: Refuse holder (container) (1), which is suitable to be placed in a pit (2). The holder comprises a bin (3), a cover (4) which is arranged above the bin (3) and has a central filling opening (16), a hook-on member (14) in the vicinity of the upper peripheral edge (11) of the bin (3), and two arms (20) which are coupled to either side of the bin (3) between the bin (3) and the cover (4). The arms (20) are vertically displaceable with respect to the bin (3), and can rotate about a horizontal axis. The arms (20) have a length which allows the bin (3), when the cover (4) has been lifted above the bin (3), to rotate from a suspended position through at least 90 DEG .

Description: Short title: Refuse holder which is suitable to be placed in a pit The invention relates to a refuse holder (refuse container) which is suitable to be placed in a pit. A known refuse holder which is suitable to be placed in a pit has a fixed top wall and a movable base. The top wall has a filling opening for tipping refuse into the holder. After the holder has been lifted above a loading space of a lorry, the base is opened, so that the refuse falls out of the container and into the loading space . The known refuse holder has the drawback that its hinged base makes the holder complicated and expensive. Also, the hinged base is difficult to use. Moreover, when the base is folded out, the known holder is emptied in one operation, a fact which impedes even filling of the loading space of the vehicle. Furthermore, there are cracks in the hinged base, through which cracks liquids, which may reach a volume of 20 litres, can flow out of the bin into the pit and, during emptying of the holder, can flow out of the bin onto the street and over the lorry. This causes unhygienic situations which can moreover deter the public from approaching the vicinity of the holder in order to deposit refuse in this holder or in adjacent holders. A further drawback of the known holder is that, as a result of normal tolerances in the dimensions of pits for use with holders produced with standard dimensions, it is difficult to position and keep the top of a holder at the same height as street level, resulting in an unattractive appearance . The object of the invention is to eliminate the drawbacks of the known refuse holder. To achieve this object, the invention provides a refuse holder according to claim 1. As a result, the refuse holder is easy and inexpensive to produce, and is also easy to use, in particular to empty into a loading space of a lorry. Furthermore, the base of the bin is sealed, so that it is impossible for liquids to flow out of the bin in an undesired manner. Further features and advantages of the invention will emerge from the following explanation in combination with the appended drawings, in which: Fig. 1 shows a refuse holder according to the invention which has been placed in a pit, which is shown in section; Fig. 2 shows a sectional view of the holder of Fig. 1 on the line II -II, with a cover of the holder in a highest position with respect to a bin of the holder; Fig. 3 shows a detail, in section, of a coupling between an arm and the cover; Fig. 4 shows a lorry with lifting and tipping means for the holder of Fig. 1; Fig. 5 shows a first position of the holder for emptying the holder into the vehicle of Fig. 4; Fig. 6 shows a second position for emptying the holder; Fig. 7 shows a third position for emptying the holder; and Fig. 8 shows a fourth position for emptying the holder. As shown in Fig. 1, the refuse holder (refuse container) according to the invention is placed in a pit 2. The pit 2 is made, for example, of concrete, and its top edge is situated in particular at street level. The refuse holder 1 comprises a bin 3 and a cover 4. The bin 3 has a curved base 6, which is supported on the bottom 8 of the pit 2 by means of legs 7. At the top, the bin 3 is delimited by a tube (or rod) 11. At one location, the wall of the bin 3 does not adjoin the tube 11. At this location, the wall has a flat plate piece 12 which extends obliquely upwards and inwards, preferably to above the underside of the tube 11. That section of the tube 11 which is opposite the plate 12 forms a hook-on member 14 which is suitable to be engaged by a hook, as will be explained below. The cover 4 has a central filling opening 16, which is delimited by a flange 17 which projects above a main surface of the cover 4 and a flange 18 which projects below a main surface of the cover 4. The top flange 17 is suitable to be received in a cavity at a bottom end of a cylindrical pillar which is to be placed on the cover 4 and via which refuse can be tipped into the bin 3. The bin 3 and the cover 4 are coupled by means of two arms 20 on either side of the bin 3. Each arm 20 has an elongate slot 21 in its bottom section, which slot extends substantially vertically after the refuse holder 1 has been placed in the pit 2. In the region of the slot 21 of each arm 20, the bin 3 has a pin 23 which projects through the slot 21 and beyond the slot 21 has a stop in order to prevent the arm 20 and the pin 23 from becoming detached from one another. The pins 23 for the two arms 20 have axes which lie in line with one another. The top end of each arm 20 is attached to the bottom side of the cover 4 by means of a coupling piece 25. The coupling piece 25 is attached to the cover 4 by means of bolts 26 and nuts 27, heads 28 of the bolts 26 being countersunk in recesses 29 in the cover 4. The top end of the arm 20 has an opening 31, through which a bearing piece 32 is inserted, which bearing piece, on the side of the arm 20 which is opposite to the coupling piece 25, has a stop section of larger diameter than the diameter of the opening 31. The arm 20, the coupling piece 25 and the bearing piece 32 are held together in a rotatable manner by means of a recessed-head screw 33. The rotatable coupling 25, 32 between each arm 20 and the cover 4 allows the bin 3 to stand not perfectly vertically in the pit 2 and/or allows the top edge 36 of the pit 2 to be not parallel to the bottom 8 of the pit 2, and/or allows the bin 3 to stand not exactly centrally in the pit 2, while the cover 4 can then still be supported centrally and around the top edge 36 of the pit 2. The result is a suitable stench seal without the cover 4 having to be placed on the bin 3 itself. Fig. 4 diagrammatically shows part of a lorry 40 with a loading body 41 which has an opening 42 at the rear and at the top. A hook 43 with a downwardly open jaw is arranged close to a rear delimiting edge of the opening 42. Two guide pieces 44 are arranged at a horizontal distance apart at a level beneath the hook 43. A hook 43 of this kind and guide pieces 44 of this kind may be arranged at a number of locations on the loading body 41, for example also on the side of the vehicle 40. The lorry 40 is provided with a lifting device which, in the example shown, comprises a telescopic arm 46 which, at its end, bears a grab part 48 which can rotate about a horizontal shaft 47. The grab part 48 fits with some play into the filling opening 16 of the cover 4 of the refuse holder according to the invention. The grab part 48 has pins 49 which can be moved radially outwards. The lifting device with the telescopic arm 46 and the pins 49 can be controlled hydraulically by an operator. When the refuse holder 1 is to be emptied, the grab part 48 is lowered into the filling opening 16 of the cover 4 until the level of the pins 49 is situated below the flange 18 of the opening 16. The pins 49 are then driven radially outwards, so that they protrude past the flange 18. The grab part 48 is then lifted, with the result that the flange 18 of the cover 4 will be supported on the extended pins 49, so that the cover 4 is also moved upwards, as indicated in Fig. 5 by the arrow 51. Only when the bottom pins 23 are supported against the undersides of the slots 21 of the arms 20 will the bin 3 be moved upwards as lifting continues. The lifting device is operated in such a manner that the bin 3 is manoeuvred between the guide pieces 44 and is then moved further upwards until the hook 43 engages over the hook-on part 14 of the bin 3, as shown in Fig. 6. If the lifting movement is continued, the bin 3, as shown in Fig. 7, will rotate about the horizontal pins 23, with the combination of the hook 43 of the vehicle 40 and the hook-on part 14 of the bin 3 acting as a pivot. The length of the slots 21 is suitable for allowing OJ NJ t H μ- in o in σ in o in and/or to the cover 4 .
