Definitions

• the present invention relates to the technical field of waste collection bins comprising a cover pivotally mounted on a vat tank around a joint.
• the lid of such a tray falls beyond a vertical position and often hits the rear wall of the tank of the tray, which is integral with the joint, which generates a noise of unpleasant snap for residents near the collection bin.
• the invention aims to allow a damping of the noise generated during the opening or closing of the lid of a tray by reducing or eliminating all or part of the aforementioned drawbacks.
• an object of the invention is a waste collection container lid intended to be pivotally mounted on a tank of the tank around a pivot axis, comprising at least one pivoting arm extending beyond a surface of the lid closing the tank, this arm comprising at least one sidewall,
• the cover also comprises a tongue, preferably formed integrally with this flank, the tongue being connected to the side via a connecting element comprising a rib of the sidewall and a deformable membrane, connected to a lateral edge of the tongue on the one hand, and to an outer edge of the end crosswise of the rib on the other hand, the tongue being configured so as to be able to undergo a deformation during its docking with an area of a fixed element of the tray, when opening the lid.
• the lid gives up some of its energy by deformation of the tongue and is therefore slowed when docking with an area of a fixed element of the tray.
• deformation for the tongue must be understood as realizing a modification of the geometry of the tongue, and / or of its relative geometry relative to the remainder of the lid, and not only a local micro-deformation of a tongue. fixed tab of plastic material, by contact with the lid.
• the side edge of the tongue is an edge extending in the longitudinal direction (larger dimension) of the tongue.
• the outer longitudinal edge of the rib is an edge extending in the longitudinal direction (larger dimension) of the rib, opposite the connection area of the rib with the sidewall.
• the tongue advantageously has a length-to-maximum thickness ratio of at least 2, and is configured so as to be able to deflect a longitudinal end edge of this tongue by an angle of at least 10 °.
• Such deflection of the tongue can absorb a variable energy depending on the thickness of the tongue, and sufficiently slow down the cover to dampen the noise significantly, even in case of residual impact against a fixed element of the tray.
• This deflection energy of the tongue is typically constant, which allows a good damping repeatability of noise during repeated opening and closing of the lid, unlike a friction energy absorption whose repeatability over time is much greater. random because the friction changes the surface state of the contact zone.
• the angle of deflection corresponds to the angular displacement of a tangent extending longitudinally, at one end of the tongue, between a "closed lid” position and a “maximum open lid” position.
• the tongue is connected to a rib of the sidewall, preferably via a connecting element comprising a membrane, preferably fold connected laterally to the tongue on the one hand and the rib on the other hand.
• the rib of the flank typically forms a typically high mechanical resistance stop, or part of such a stop, this stop being advantageously also a stroke limiter preventing the direct impact of the part of the cover which covers the tank on a rear wall of the tank, during an opening of the lid.
• the membrane is adapted to allow a deflection of a longitudinal end edge of the tongue, and then, typically, to exert a restoring force on the tongue after deflection.
• a restoring force contributes to allow the tongue to return to its initial position, which substantially avoids a progressive plastic deformation, as and when repeated opening of the lid.
• the tongue and the rib extend transversely substantially perpendicular to the sidewall and are directly connected to one of their longitudinal ends. This makes it easier to mold the lid in one piece.
• the tongue is, at least after a first opening of the lid, typically not connected directly to the side by a transverse edge (it is preferably connected to the flank via the rib and the membrane). This allows a deformation, for example a deflection of the tongue.
• the lid comprises the membrane, typically folded, which then advantageously comprises at least a first wafer having a length to thickness ratio of at least 4, integral with the tongue, a surface of the tongue and a surface of the first wafer forming an angle that can vary during the deflection of the tongue.
• the deformation of the pleated membrane makes it possible to absorb a complementary energy, and to increase the damping effect associated with the energy absorption during the deflection of the tongue.
• the folded membrane also comprises a second wafer having a length to thickness ratio of at least 4 integral with the tongue and the first wafer, forming with the first wafer, on either side of a lateral connection fold, damping bellows angle dihedral may vary during the deflection of the tongue.
• This damper bellows therefore adds a complementary damping effect.
• the first and second pads may have the same or different thicknesses.
• the first wafer, and the second wafer have an identical thickness of between 0.3 mm and 1 mm, less than 25% less, and preferably less than 40% greater than a maximum thickness of the tongue.
• the bellows can thus behave like a relatively thin folded membrane (the fold corresponding to the edge of the dihedron), which increases its flexibility and allows a high repeatability of openings and closures without notable irreversible deformations.
• the first wafer and the second wafer are configured to exert together a restoring force on the tongue adapted to bring the tongue, when the lid is open and without pivoting speed, in a position of this tongue when the lid is closed on the tank.
• the bellows acts as a return spring, preventing the tongue remains bent with significant deflection during extended periods of opening of the lid. This prevents permanent deformation of the tongue.
• the first wafer and the second wafer each have a generally triangular flat shape having a common edge along the fold, optionally truncated at one end of this common edge. They thus typically form a triangular bellows around a vertex, (or triangular truncated at the top), which leads to a high mechanical resistance to deformation, the relative deformations in the area of the summit requiring increased stresses.
• the tongue is, before any use of the lid, separated from the side along one of its longitudinal edges.
• the tongue is, before any use of the lid, connected along a lateral and longitudinal edge to said side via a thickness connecting element. lower than a maximum thickness of the tongue, and such that this connecting element can be broken during a first opening of the lid.
• This thin connection of the tongue to the sidewall is easier to make in molding than a separation, by a typically narrow space, of the tongue and the sidewall, as implemented according to the first option of manufacturing the lid.
• two longitudinal surfaces, respectively of the tongue and the rib form an angle of between 30 ° and 90 ° when the cover is closed, this angle being capable of being reduced by a value between 15 ° and 60 ° when an opening of the lid.
• the configuration of the tongue and rib forming an angle between 30 ° and 120 ° mechanically reinforces the assembly [tongue / lateral and longitudinal connection element / rib], compared to a design in which the tongue would be parallel to the rib . This angle also allows a significant angle of deflection of the tongue (15 ° to 70 °).
• the invention also relates to a waste collection bin, with a capacity of between 60 and 360 liters, including terminals, characterized in that it comprises a lid as defined above.
• Such a tray typically comprises a lid comprising a set including the tongue, rib, and membrane, which forms a stroke limiter, arranged and configured to, upon opening of the lid, contact an area of a stationary member of the tray to prevent contact between a lid surface closing the vessel and a wall surface of the vessel.
• the noise when opening the lid is then amortized for several reasons:
• said area of a stationary member of the tank is a surface of a rear handle arm of the tank, for example an edge surface of a side of the rear handle arm of the tank.
• the assembly formed by the tongue, the rib, and a connecting element between this tongue and the rib is configured so that the deflection of the edge of the tongue during an opening of the lid is substantially elastic, to allow a repeatable damping during successive openings of the lid.

• the cover arm 10 also comprises a tongue 14 which also extends transversely perpendicularly to said sidewall.
• the tongue 14 is not directly connected to the sidewall 11 on its lateral edges, so as to be able to undergo a deformation during its docking with a zone 16 of a fixed element of the tray (typically an edge surface of a sidewall of the rear handle arm 17 of the tank), when opening the cover. More specifically, the tongue 14 is configured so as to be able to deflect a longitudinal end edge of this tongue by an angle of at least 10 °.

• This folded diaphragm 18 serves two functions:
• the membrane provides a restoring force on the tongue adapted to bring the tongue, when the lid is open and without pivoting speed, in a position of this tongue when the lid is closed on tank.
• the tongue is returned to a normal position (position when the lid is closed), even if the lid remains open for long periods. This makes it possible to keep the same position of the tongue in time and to avoid its deformation by creep and / or because of the successive deformations.
