    Extractable collector bin for underground waste container
    The present invention relates to an extractable collector for underground waste container, buried or semi-buried type.
    It also relates to a series of bins of this kind, of different categories.
    Conventionally, an underground waste container has the shape of a substantially cylindrical vessel, of vertical axis, a large part -bottom-bottom is buried while its upper part-side mouth-spring out of the ground; this part, accessible to users, is usually lined externally with a wall of aesthetic character, for example surrounded by a wooden cladding, and is headed by a hard polyethylene lid provided with an opening provided with a hatch, This allows users to introduce any kind of waste, both domestic and industrial or of vegetable origin. As an indication, the buried length of the tank is generally about two thirds of its total length.
    Inside the tank is inserted an extractable collector, which is emptied periodically, this operation being done traditionally with the help of a crane mounted on a truck pickup and delivery of waste to a center of ad hoc treatment, with a view to their recycling or incineration, for example.
    A known collecting pan comprises a pair of rigid annular belts, one high, the other low, connected to each other by a tubular sheath, and the lower belt is equipped with a bottom hatch, of which the opening for emptying is manually controlled by means of a rope.
    This operation, as well as the closing of the hatch after emptying, is not easy and is not always well controlled by the operator.
    The upper belt is provided with a series of lifting brackets, for example four in number, regularly distributed at its periphery, through which it is possible to extract and handle the tray by means of the crane.
    The binding of these fasteners with the hook of the crane is generally done by means of flexible links such as chains (in four points therefore), which requires inconvenient and relatively tedious manipulations on the part of the operator, this both at the beginning and at the end of the operation.
    This operation is repeated many times during a collection drive by a truck, so that the total duration of this tour is long, which is not satisfactory economically.
    It has also been proposed to fix the lid of the container to the collecting tray, and to provide this lid with a central ring with which the hook of the crane can come into engagement; thus the lifting of the lid induces that of the collecting tray, since it is integral with the lid.
    Such an arrangement allows in principle to facilitate the emptying operation, and to make it faster; However, it has the major disadvantage that the forces developed by the crane boom to extract the collector (which is usually filled, and therefore heavy) out of the tank pass through the wall of the polyethylene cover, the resistance is not not suited to this function.
    This results in deformations and a risk of rapid deterioration or even breakage of the lid during handling, which is a source of danger for the operator.
    Unless solid lids, very resistant and expensive metal, this solution is therefore not completely satisfactory.
    The invention aims to solve these difficulties.
    It relates to an extractable collector for an underground waste container, which comprises at least one pair of rigid annular reinforcing belts, one high and the other low, connected to one another by a tubular sheath, the lower belt being equipped with a dump hatch.
    According to the invention, the upper belt is integral with a frame provided with a central gripping member allowing the extraction of the tray out of the waste container, its handling for emptying, and its reinsertion in the container. waste with a crane or similar hoisting device.
    It is therefore this armature, whose mechanical strength is chosen to fulfill such a function, which ensures the transmission of forces between the hook of the crane and the tray.
    Furthermore, according to a number of additional, non-limiting features of the invention: the reinforcement is a beam which extends substantially diametrically with respect to the upper belt, and the gripping member is positioned in the center of this beam; - the collecting tray being adapted to be inserted inside a waste container provided with a lid pierced with a central orifice, and curved wall whose convexity is directed upwards, on the one hand, said beam has the general shape of a vault, arched or angular, adapted to be housed under the cover, by being generally inscribed in the concavity thereof, and, secondly, said gripping member is adapted to cross said central orifice, so that the lid can be handled at the same time as the tray during the emptying operation thereof (the lid is however not subject here to the lifting and handling of the tray, since it is the beam that cash them); the gripping member is equipped with a control means for opening and closing the hatch equipping the lower belt; this control means is kinematically connected to the hatch equipping the lower belt by means of a linkage positioned against the inner face of said sheath; - The hatch equipping the lower belt comprises a pair of hinged flaps whose pivoting is controlled by translation of the control means along the axis of the sleeve; - The hatch consists of a single hinged flap, and the lower belt is provided with a mechanical feeler member, adapted to control the opening; - The collector has a polygonal section, for example octagonal; - The dimensions of the lower belt are a little lower than those of the upper belt, so that the tray has a slightly flared configuration from bottom to top; the sheath has a light, rigid or semi-rigid structure.
    Other features and advantages of the invention will become apparent in the light of the description which will now be made, with reference to the accompanying drawings.
    On these drawings:
    Figure 1 shows schematically, in axial section, an underground waste container in which is housed an extractable collector tray according to the invention; - Figure 2 is a schematic perspective view of a first possible embodiment of this tray; FIG. 3 is a view from above of FIG. 2; - Figure 4 is a schematic perspective view of a second possible embodiment of the tray; - Figures 5 and 6 are front views and respectively side of the tray of Figure 4; - Figure 7 is a schematic perspective view of a third possible embodiment of the tray; - Figures 8 and 9 are front views and, respectively, side of the tray of Figure 7; FIGS. 10 and 11 are diagrams showing control principles of hatch flaps that apply, respectively, to the second and third embodiments of the tray.
    The waste container A illustrated in FIG. 1 comprises a semi-buried generally cylindrical tank of vertical axis, the wall P of which is sunk and retained in a well dug in the ground S, about two thirds of its length. . References C and D denote, respectively, a cover which covers the aboveground wall portion, and the bottom wall of the vessel.
    A peripheral rib N promotes the anchoring of the container in the ground.
    As seen in the figure, the wall of the tank comprises three portions of slightly decreasing diameter, from top to bottom.
    In known manner, the lid C has a curved wall (in the form of a spherical cap) whose convexity is directed upwards, and has at least one opening provided with at least one hatch (not shown), allowing users to introduce the waste into the container, although the lid is attached to it.
    It is pierced with a central orifice O.
    This tank contains an extractable collecting tray 1 according to the invention, which comprises a pair of rigid annular reinforcing belts, one high 3, the other low 4, connected to one another by a tubular sheath 5 .
    The axial length of the tank corresponds substantially to that of the tank, or is a little less than this length.
    The lower belt is equipped with a dump hatch 6, while the upper belt is secured to a frame 2 provided with a central gripping member 7.
    The armature 2 is a beam which extends transversely, diametrically with respect to the upper belt 3, and has a generally angular shape - in this case trapezoidal - so that it forms a vault which can be housed just below the lid, by registering globally in the concavity of it.
    The beam 2 is a profile having a section "U" returned, whose height is substantially greater than the thickness.
    The gripping member 7 is positioned in the center of this beam 2 and is directed upwards, so as to pass through the central orifice O of the cover.
    It is understood that by this arrangement, the lid (after having been separated from the mouth of the fixed vessel) can be lifted at the same time as the tank when it is extracted out of this tank by means of a device. lifting, previously engaged with the gripping member 7. During this handling, the cover C rests on the beam 2, but is not mechanically stressed.
    The belts 3 and 4 and the beam 2 are made of metal with high mechanical strength, for example steel. The beam 2 is connected to the upper belt by known fastening means, by welding or using screws, for example.
    The tubular sheath 1 is made of rigid or semi-rigid material, or even flexible, metal, plastic or synthetic fabric for example. It is connected to the upper and lower belts by known fastening means, possibly removably, by stapling or using screws, for example.
    This sleeve preferably has a light structure, for example based on thin sheet or plastic, which can be reinforced by longitudinal members connecting the two belts.
    Belts 3 and 4 advantageously have the shape of a regular polygon, for example octagon or hexagon. Its section is chosen to register just (without excessive play) in the circular section of the tank, which reduces friction during the extraction and replacement of the tray inside the latter.
    Indeed the contact areas are linear (located only at the edges of the polyhedron), and not surface.
    Taking into account the slight reduction in the internal diameter of the tank from top to bottom, the lower belt 4 has adapted dimensions, slightly smaller than those of the upper belt 3, and the section of the sheath 5 - which can also be polygonal - decreases also from top to bottom, correspondingly.
    The upper edge zone of the inner wall of the tank A is advantageously provided with a shoulder (not shown) on which the upper belt 3 rests when the tank is properly inserted into the tank, this shoulder thus supporting the weight of the tank. and its contents.
    The tray which is the subject of the first embodiment illustrated in Figures 2 and 3 has an octagonal section; it comprises a hatch 6 with a single flap, constituted by a rigid pivoting plate 60 forming a bottom element. It has an octagonal shape identical to that of the lower belt 4 and is articulated thereto around a hinge 600, axis AA, which is carried by one of the sides of the octagon. The opposite side is equipped with a mechanical locking member 601 of the type of door bolt, for example, which normally holds the raised bottom member 60 in its closed position. This member 601 is provided with a mechanical probe 602 able to cause the unlocking when it is actuated, which then causes the hatch to open by pivoting the bottom element 60 downwards about the axis AA , which empties the tank. In practice, the actuation for opening the hatch is done by bearing the probe on the edge of the truck collection bucket.
    The rearming of the system to close the bottom is done automatically by the crane operator when the emptied trapdoor comes to rest on the ground-in this case in the bottom of the container- when it is put back into place therein.
    In this first embodiment, the gripping member 7 which is provided with the beam 2 is simply a handle (or hoop) 70 shaped to receive the hook of the lifting device, by means of which the extraction takes place. full container out of the container, its handling and its replacement in the container after emptying. The opening of the hatch 6 for emptying, then its closure after emptying, are done here manually. The handle 70 is so dimensioned that it can pass through the central opening of the lid, so that after separation of the lid with the container, the tray and the lid can be lifted and handled together.
    We will call conventionally tray model that is the subject of this first embodiment "single vane tray and control probe."
    The second and third embodiments illustrated in FIGS. 4 to 6 and, respectively, 7 to 9 are distinguished from the first embodiment essentially by the fact that, on the one hand, the bottom hatch of the collecting tray is composed of two pivoting flaps, rigid structure, and that, on the other hand, the control of these flaps, both for their opening (emptying) than for their closure, is carried out from the gripping member itself, this via a system of appropriate movement transmission.
    The block diagram of FIG. 10 illustrates the control mode of the pivoting flaps corresponding to the second embodiment, a principle which, applied to rigid containers, is known in the art under the designation KINSHOFER system (registered trademark).
    In this figure, reference 1K denotes the container, which is provided at its base with a pair of flaps 61a-61b articulated about axes aa, respectively bb. The gripping member 7 of the container, secured to its upper wall, has the shape of a tube 71 with a vertical axis, and its upper end is provided with an annular flange 71a for gripping and handling the container. , this using an ad hoc clamp which is equipped with the lifting device (not shown).
    In this tubular member is mounted and guided axially a sliding rod 710 whose upper end is provided with a base 711 cup-shaped and whose lower end, which is inside the container, is provided with a wafer 712 to which are attached a pair of flexible links 9a-9b, such as cables or chains. At their lower end, these links are each attached to the inner face of one of the two hatch flaps 61a, respectively 61b.
    With the simple observation of FIG. 10, it is understood that a displacement in axial translation, from the bottom to the top, of the rod 710 (arrow Z) induces the pivoting of the flaps in the direction of the closure of the hatch (arrows Ya and Yb). Conversely, a movement from top to bottom of the rod 710 allows the free opening of the hatch.
    With reference to FIGS. 4 to 6, the principle of control of the hatch flaps 61a, 61b is applied to the container that forms the subject of the invention. The gripping member 7 -conformed and dimensioned so as to pass freely through the central orifice of the lid of the container- is here secured to the frame 2 in the form of a beam. The hatch flaps 61a-61b each have the shape of a half octagon, corresponding to one half of the bottom of the tray.
    The flexible links that control these parts are here referenced 9 and 9 '.
    The beam 2 has a cross-section in the approximate shape of an inverted "U", which delimits an interior space open downwards, in which the upper portions of the links 9, 9 'pass; in addition, these are guided by return rollers 20 mounted at the base of the ends of the beam, in the vicinity of the inner wall of the tray. Each of the links 9 and 9 'then descends vertically along this inner wall, and its lower end is attached to a lateral rod 8, respectively 8', guided in axial translation in a slide 800, 800 'integral with the sleeve. The two rods 8 and 8 'have diametrically opposite positions relative to the axis of the sheath.
    The two flaps 61a, 61b constituting the bottom hatch 6 also have diametrically opposite positions relative to the axis of the sheath (and the lower belt 4 to which they are articulated). However, they are oriented at 90 ° angle around this axis relative to the rods. At its lower end, each rod 8 and 8 'is connected to the two flaps 61a, 61b via a pair of articulated rods 80a-80b and 80'a-80'b respectively.
    Each set of rods forms an inverted "V" (open downward), whose apex angle depends on the vertical position of the associated rod.
    It is understood that in this way, an upward traction on the rod 710 causes traction on the links 9, 9 'and correspondingly the ascent of the rods 8, 8', which causes the two flaps 61a, 61b to pivot together around each other. their respective axes aa, bb, in the direction of closure.
    The gripper fitted to the lifting and handling device used to extract the tray 1 out of the container and empty it can be of the same type as that used for rigid containers system KINSHOFER (registered trademark).
    This clamp is adapted to grip the annular flange 71a for the gripping and handling of the tray, while it keeps the base 711 locked in the up position, so that the bottom hatch 6 remains closed.
    For emptying, it unlocks the base, so the rod 710 can slide freely downwards, so that the two flaps open naturally under the effect of gravity and the weight of waste in the tray.
    After emptying, the clamp returns the annular flange 71a in its upper position, which closes the hatch.
    The emptied tank, closed bottom, can then be reintroduced into the container.
    These operations can be done automatically, without manual intervention of the person who proceeds to the collection.
    It will be noted the presence, a little above the beam 2, of an annular flange 713 surrounding the tube 71 of the gripping member 7. Its function is to serve as a seat at the edge of the opening O of the cover and thus keep it properly centered when moved together with the bin during handling.
    The lateral positioning of the control links 9 and 9 '(partially further protected in the semi-closed beam 2) and the motion transmission linkage 8, 80; 8 ', 80' prevents these mobile elements from being exposed to the waste introduced and contained in the tank 1, which reduces the risk of premature wear, pollution and jamming of the system.
    It will be conventionally called the tray model which is the subject of this second embodiment "tray with two flaps, closing by pulling upwards".
    The schematic diagram of FIG. 11 illustrates the control mode of the pivoting flaps corresponding to the third embodiment, a principle that is applied to rigid containers and is known in the art under the designation EASY system (Registered trademark).
    In this figure, reference 1E denotes the container, which is provided at its base with a pair of flaps 62a-62b articulated about axes aa, respectively bb. The gripping member 7 of the container, secured to the upper wall of the container, has the shape of a tube 72, of vertical axis, and its upper end is integral with an annular collar 72a for gripping and handling. of the container using an ad hoc clamp which is equipped with the lifting device (not shown). In this tubular member is mounted an axially sliding rod 720 whose upper end protrudes upwardly above said collar 72a, and whose lower end, which is inside the container, is provided with a return roller 721. This serves as a fulcrum and thrust to the central zone of a flexible link 9, such as a belt. The latter passes over a pair of guiding and return rollers 720a, 730b whose position is fixed; they are arranged laterally on each side of the movable roller 721, at a level slightly greater than this one. This double return system has the general reference 73.
    This arrangement gives the link 9 the general shape of the letter "M" whose side branches bear the references 9a, 9b. Each of these branches is fixed at its lower end to the inner face of a hatch flap 62a, respectively 62b.
    With the simple observation of FIG. 11, it is understood that a displacement in axial translation, from top to bottom, of the rod 720 (arrow Z ') induces a thrust of the roller 721 at the center of the belt 9. This results pulling upwards on its lateral branches 9a, 9b, which makes the flaps pivot in the direction of closing the hatch (arrows Ya and Yb). Conversely, a movement from the bottom to the top of the rod 720 allows the opening of the hatch.
    Referring to Figures 7 to 9, it is found -appliqué to a tray according to the invention - the same control principle flap shutters 62a, 62b. The gripping member 7 is here secured to the frame 2 in the form of a beam. This is provided with a central housing containing the double-return system 73 described above.
    The hatch flaps 62a-62b each have the shape of a half octagon, corresponding to half of the bottom of the tray.
    The flexible links (constituted by the lateral branches of the belt in the form of "M") which control these flaps are here references 9 and 9 '.
    The motion transmission linkage between these links and the hatch flaps is the same as in the second embodiment described above.
    The beam 2 has a cross-section in the approximate shape of an inverted "U", which delimits a semi-closed space, but open downwards, in which pass the upper portions of the links 9, 9 '; in addition, these are guided by return rollers 20 mounted at the base of the ends of the beam, in the vicinity of the inner wall of the tray. Each of the links 9 and 9 'then descends vertically along this inner wall, and its lower end is attached to a lateral rod 8, respectively 8', guided in axial translation in a slide 800, 800 'integral with the sleeve. The two rods 8 and 8 'have diametrically opposite positions relative to the axis of the sheath.
    The two flaps 62a, 62b constituting the bottom hatch 6 also have diametrically opposite positions with respect to the axis of the sheath (and the lower belt 4 to which they are articulated). However, they are oriented at 90 ° angle around this axis relative to the rods. At its lower end, each rod 8 and 8 is connected to the two flaps 61a, 61b via a pair of articulated rods 80a-80b and 80'a-80'b respectively. Each set of rods forms an inverted "V", open downward, of variable angle which depends on the vertical position of the rods.
    It is understood that thus, a downward thrust on the rod 720 causes a high traction on the links 9,9 'and correlatively the rise of the rods 8, 8' which causes the joint pivoting of the two flaps 61a, 61b in the sense of closure, around their respective axes aa, bb.
    The gripper fitted to the lifting and handling device used to extract the tray 1 out of the container and empty it can be of the same type as that used for rigid containers with EASY system (registered trademark).
    This clamp is adapted to grip the annular flange 72a for the gripping and handling of the tray, while it keeps the rod 720 depressed and locked in the low position, so that the bottom hatch 6 is kept closed.
    For emptying, it unlocks the rod 720, which is then free to slide upwards, so that the two flaps open naturally under the effect of gravity and the weight of the waste contained in the tray.
    After emptying, the clamp returns the rod 720 to its lower position, which closes the hatch.
    The emptied tank, kept closed bottom, can then be reintroduced into the container.
    These operations can be done automatically, without manual intervention of the person who proceeds to the collection.
    It will be noted the presence, a little above the beam 2, of an annular flange 723 surrounding the tube 72 of the gripping member 7. Its function is to serve as a seat at the edge of the opening O of the lid and keep it centered when moved along with the bin during handling.
    We will call conventionally the tray model which is the subject of this third embodiment "bin with two flaps, push down closure".
    The lateral positioning of the control links (partially further protected in the semi-open beam 2) and the motion transmission linkage 8, 80; 8 ', 80' prevents these mobile elements from being exposed to the waste introduced and contained in the tank 1, which reduces the risk of premature wear, pollution and jamming of the system.
    The high and low end belts could of course have a circular shape, the sheath connecting them being in this case cylindrical or slightly frustoconical (flaring upwards).
    The invention also relates to a series of collection bins according to the invention, comprising at least two bins of different categories, taken from the following three categories: a) single vane tray and control probe; (b) two-section trough with pull-up closure; (c) double-sided, push-down closed tank.
    The invention is remarkable in that the frame which is provided with its upper belt is identical for each of the bins of the series.
    This frame, vault vault for example, being the same for each category of tray, production costs are significantly reduced when it is the same company that manufactures two or three different kinds of tray.
    It suffices to mount on this common frame the ad hoc gripping member, as well as, where appropriate (for the models (b) and (c) above) the appropriate control means of the flap flaps equipping the low belt.
