Definitions

  • the present invention is in the field of waste collection, it concerns public waste containers and more particularly relates to a system for introducing this waste - in particular in the classic form of household waste bags - which makes it possible to calibrate the volume of waste deposited.
  • the realization of a calibration responds to the progressive implementation, by the various public and private operators, of the polluter-pays principle, which leads these operators to set up pricing systems based on the volume of waste deposited by a user. This implies an evaluation of the quantity of waste that will be treated, which is done at the level of the system for introducing the waste into the containers.
  • the waste collector includes and makes available to users, through its introduction system, a volume capacity that it is not possible to exceed during each manipulation of said system.
  • Such a system must also be equipped with a handle and/or an opening pedal that can be operated by users to move from a closed position of the system to an open position for introducing waste.
  • actuation angles of these devices are limited by the shape of the waste introduction systems, which are dependent on the particular configuration linked to the double rotating cylinder. They are also limited by the very shape of the waste containers. The ergonomics and practicality of these operating devices can therefore be improved.
  • the present invention overcomes these drawbacks by proposing a mechanically less complex structure, easy to use and reliable in calibrating the volumes of waste dumped.
  • the simplicity of the design is in this case a guarantee of robustness.
  • the configuration has also been designed to facilitate its handling by users.
  • the waste container of the invention conventionally comprising a casing surmounting the waste storage container, in which is made an opening for introducing the waste which can be closed by a hatch which can be moved by the user by operating means between an open position for introducing the waste and a closed position for emptying the waste, is such that the hatch is a solid wall of a single drum rotatably mounted in the casing, said drum comprising a window positioned opposite the opening of the casing in a first position of the operating means corresponding to the open position for introducing the waste and positioned directly above the container in a second position of the operating means corresponding to the closed position for emptying the waste, the opening of the casing being completely blocked by the drum in this second position of the drum, return means being provided to return the drum to said second position.
  • the configuration in this case is based on a single rotating cylinder or drum, which considerably simplifies the structure and allows for rethinking the means of its actuation.
  • the structure is designed in such a way that no waste can reach the container if the drum is in its open position, with its window accessible to the user via the opening in the casing. Conversely, in the closed position, no access to the drum is possible.
  • the operating means in the structure of the invention, are designed to drive the drum through a rotation greater than 180° and less than 220°. Preferably, this is a rotation of the order of 200°, the drive of which is not carried out directly on the drum, for obvious practical reasons.
  • This significant angular displacement is necessary due to the existence of a single drum. It also results from the configuration of the casing, and meets the need to avoid any removal waste parasite between the two open and closed positions. Finally, it results from design choices, the drum window being for example large, both to facilitate its filling and to guarantee its emptying. Thus, for example, according to the invention, the angular sector covered by the drum window is close to the diameter of the drum.
  • the respective shapes of the drum and the casing leave minimal clearance, on the one hand between the edges of the opening made in the casing and the drum, and on the other hand between the wall of the casing opposite the opening and the drum.
  • minimal clearance is meant minimal functional clearance, which could be translated by the fact that there is no clearance between the shapes or volumes respectively outside the drum and inside the casing.
  • the operating means may comprise a handle rotating relative to the casing according to a predetermined stroke of amplitude between 90° and 110°, connected to the axis of rotation of the drum by a mechanism multiplying the rotary stroke of the handle, achieving a multiplication by a factor between 1.9 and 2.1 of the rotary stroke of the drum.
  • the multiplication factor is of the order of 2.
  • the handle being offset from the trapdoor formed by the drum, generally arranged laterally to the casing and therefore freed from the constraints specific to the movement of the drum, the operation is easy for users.
  • the stops limiting the amplitude of the stroke are therefore also managed at the level of a rotating device of the handle which is separate from the drum/housing structure. This separation of functions results in an improvement of the overall robustness, each of the functions being able to be analyzed individually in order to be optimized for the proper functioning of the system.
  • the multiplication mechanism comprises a drive wheel integral with the rotation axis of the handle, connected by a chain or a belt to a drive wheel integral with the rotation axis of the drum.
  • the principle being thus established it may be a question of toothed wheels cooperating with a chain, friction wheels cooperating with a belt, etc.
  • the operating means may comprise a pivoting pedal with an angular movement of between 15° and 25°, which may be connected to the rotation axis of the drum by a mechanism that multiplies the pedal stroke, thereby multiplying the rotary stroke of the drum by a factor of between 8 and 13.
  • Each action on the pedal causes the waste introduction system to open and initiates the calibration operation, which ends when the pedal is released, the drum then being in the waste emptying position.
  • the amplitude of rotation of the pedal is of the order of 20°, for ergonomic reasons.
  • each container may be provided with two operating members operable in combination, and the operating means in this case comprise a pivoting pedal with an angular movement always between 15° and 25°, connected by connecting means to the handle travel multiplier mechanism.
  • the handle travel multiplier mechanism A single multiplier mechanism is then used, which simplifies the system.
  • this multiplication mechanism is as described above - that is to say based on two wheels, a drive wheel integral with the axis of rotation of the handle connected by a belt or a chain to a drive wheel integral with the axis of rotation of the drum -
  • the connecting means consist of a cable or a connecting rod pivotally mounted on the one hand on the pedal and on the other hand on the periphery of a rotary device of the handle, into a pivot axis capable of transforming the angular displacement of the pedal into a rotation of said rotary device of the handle covering the amplitude of the predetermined stroke of said handle.
  • Actions on the pedal therefore cause a complete rotation of the handle, according to the predetermined amplitude, and move the drum by an angular sector allowing it to pass from the second closed position to the first open position for introducing waste.
  • Return means may be provided to return these operating means to the second position of the drum, which allows the waste to be emptied and corresponds to the closing of the hatch, for example comprising a traction spring interposed between the pedal and a drum support, which may also be covered by the casing.
  • the stable rest position in the absence of any action, is logically the closed position, and the return means lead there after each operation on the handle and/or the pedal.
  • the calibration function which results in a cycle of opening, introduction of waste and closing/emptying, actually imposes this “normal” state of closure without actuation.
  • the division into two successive phases first of opening carried out by hand or foot by the user and then of automatic reclosure, can be controlled, with a view to invoicing, by an electronic identification and authorization unit cooperating with an electromechanical device for locking/unlocking the drum.
  • the container comprises a casing 1 surmounting the waste storage container 2 (or bin), which can be buried underground.
  • This casing 1 comprises an opening 3 in front of which a rotating drum 4 rotates along a horizontal axis.
  • the drum is rotatably mounted on a support structure, for example of the gantry type, which is covered by the casing 1.
  • the drum 4 rotates in the casing 1 in such a way that if a solid wall of said drum 4 is placed in front of the opening 3, it is not possible to introduce waste.
  • the drum 4 acts like a pivoting trapdoor. It comprises a window 5 (shown in crossed hashed lines) which moves according to the rotation of the drum 4.
  • this window 5 is located successively opposite and opposite the opening 3, overlooking the storage container 2, and finally in an intermediate position between the latter.
  • the opening 3 is delimited, on its upper and lower sides, by panels 6, 7 of the casing, and it is generally rectangular.
  • the casing also delimits it on its lateral sides.
  • the window 5 of the drum 4 is also rectangular in appearance, covering an angular sector greater than that of the opening 3, which has been specified to be preferably close to the diameter of the drum 4 in order to facilitate the introduction of the waste and especially its emptying, in the position of the Figure 2 .
  • the casing 1 and the drum 4 are designed so that the casing makes it possible to conceal any possibility of waste passing between the drum 4 and the casing 1, whatever their relative position, since there is no play.
  • the angular displacement of the window 5 of the drum 4 is sufficiently large to ensure that, in the emptying position of said drum 4, the two transverse sides delimiting the window 5 are at a distance from the two horizontal edges delimiting the opening 3, and outside the surface of this opening 3.
  • the means of maneuvering the movement of the drum 4 available to the user are shown in figures 4 to 6 and allow it, by action on these means, to move from a stable closed rest position to an open waste introduction position, before automatic return - due to the return means - to the closed emptying position.
  • the handle or lever 10 is in the high position at rest, and can be lowered to move the drum 4 from its position of the Figure 2 towards that of the Figure 1 , in the open waste introduction position.
  • An action on the pedal 20 has the same effect.
  • These two members 10, 20 have a rotary stroke amplitude - around rotation axes 11, 21 - limited by stops of the system.
  • a mechanism multiplying the stroke of the handle 10 is shown in Figure 6 : a 12 toothed wheel secured to the rotation axis 11 is connected via a chain 13 to a second toothed wheel 14, of smaller diameter, secured to the rotation axis of the drum 4.
  • the respective diameters of the wheels 12, 14, and consequently the number of teeth of each of these wheels 12, 14, are chosen to amplify the angular travel of the wheel 12, in this case by a factor of order 2. More precisely, the angular travel of the handle 10 is provided to be of the order of 100°, and that of the drum 4 driven by the wheel 14 is of the order of 200°. This latter value corresponds to the amplitude of the rotation that one wants to give to the drum 4 so that it can fulfill its introduction/emptying function in connection with the configuration given to the calibration system of the invention.
  • the pedal 20 results in the same rotation effect for the drum 4, also controlled between its closed rest position of the Figure 2 and the opening position of the Figure 1 .
  • the multiplication problem is a little different, knowing that the rotational amplitude of a normally ergonomic pedal is of the order of 20°.
  • a single mechanism is used, and the pedal 20 is for this purpose connected to a rotary device 15 of the handle 10 by a connecting rod 30 articulated on the one hand on the pedal 20 at an axis 31, and on the other hand on said rotary device 15 of the handle 10, at an axis of rotation 32.
  • the articulation 31 in the vicinity of the location of action of the foot on the pedal 20 guarantees that the amplitude of the movement is close to that which exists at the level of the pedal 20.
  • the articulation 32 is located on the periphery of the rotary device 15 of the handle 10, device 15 which takes for example the form of a plate to which said handle 10 is secured and which manages the rotation relative to the casing 1 and the rotary connection 32 with the connecting rod 30.
  • the location of this articulation 32, in the immediate vicinity of the base of the handle 10, makes it possible to give its rotary device 15 substantially the same angular travel as when it is actuated by a user directly via the handle 10.
  • the rotary travel of the drum 4, when it is driven by the pedal 30, is therefore the same as when it is controlled by the handle 10.
  • Return means in the form of a traction spring 40, are interposed between the pedal 20 and the structure of the container of the invention, at the level of a fin 51 protruding from one of the uprights 50 of a gantry supporting the rotation of the drum 4.
