Description

[0001] The invention relates to voluntary waste collection containers comprising a lid, and more particularly to a device for opening such a lid.

[0002] Containers for voluntary waste contribution, whether they are aerial columns for voluntary waste contribution, for example comprising emptying hatches on a lower face of the contribution column, or large volume containers, may comprise a cover in order to close a waste introduction opening.

[0003] In order to be able to open the lid of the container easily, in particular when an individual bringing their waste to the container carries waste to be placed in the voluntary contribution container, it is known to install a lid opening device which, by its actuation, allows the lid to be opened so as to free the waste introduction opening and thus to be able to place the waste in the voluntary contribution container.

[0004] The lid opening device works as follows: the user presses a pedal to open the lid. The force exerted by this pedal is transmitted to the lid via tie rods connected to the pedal and the lid. The tie rods are placed on side faces of the container on either side of the lid, the pedal being placed on a front face of the container, i.e. the face in front of which a user stands in order to deposit their waste in the voluntary contribution container. An example of such a lid opening device is known from document ES 1 233 409 U.

[0005] A lid opening device according to the prior art has disadvantages related to the positioning of the tie rods. Indeed, and in the case of a container comprising emptying hatches forming the lower face of the latter, such placement of the tie rods at two lateral faces of the waste supply container, and extending over the entire height of these faces, could lead to placing the tie rods in areas already comprising means for opening the emptying hatches. This could therefore lead to unwanted clutter in areas where the voluntary supply container is handled by an operator.

[0006] In addition, the tie rods must be protected, whether they are placed outside the voluntary contribution container (in order to protect them against impacts that could lead to damage to the tie rods and therefore to a malfunction of the lid opening device) or inside the latter (in order to avoid blocking the movement of the tie rods by the waste already stored in the voluntary contribution container). To this end, it may be necessary to provide tie rod protection devices, similar to boxes in which the tie rods are housed. This leads to design complexity, a multiplication of parts to form the voluntary contribution container and a loss of waste storage volume in the case where the tie rods are arranged inside the voluntary contribution container.

[0007] The aim of the invention is to provide a device for opening a lid of a voluntary waste collection container that is less troublesome than those of the prior art and less exposed to damage and blockages than those of the prior art, while avoiding a loss of waste storage volume.

[0008] To this end, the invention relates to a container for voluntary waste delivery comprising a main body forming a waste collection volume, at least one opening for introducing waste into the voluntary delivery container and a cover which can rotate between a first position closing the opening for introducing waste and a second position in which the opening for introducing waste is accessible, the voluntary delivery container comprising a device for opening the cover comprising: a lid opening pedal arranged on one face of the main body and movable between a rest position and an activation position in which the lid is open, at least one force transmission cable connecting the lid opening pedal to the lid, the lid opening device being configured so that actuation of the lid opening pedal causes the lid to open by pulling the force transmission cable on the lid, the cable being arranged on the same face of the main body as the lid opening pedal.

[0009] Thus, a cover is obtained comprising at least one force transmission cable arranged on the same face as the cover opening pedal. This arrangement makes it possible to free faces of the voluntary contribution container on which other means can be arranged, for example those allowing the opening of emptying hatches forming a lower face of the voluntary contribution container in the event of emptying from the bottom of the voluntary contribution container. In addition, the flexibility of the cable allows the latter to be placed in the main body so as to avoid blockage of the cable by waste and therefore an impossibility of opening the cover, while not encroaching on the waste storage space. In addition, the flexibility of the force transmission cable(s) allows greater freedom in installing the cover on the main body due to the ease of arrangement of the cable(s) thanks to their flexibility.

[0010] Depending on other optional characteristics of the voluntary contribution container taken alone or in combination: the cover is arranged on the same face of the main body as the cover opening pedal and the force transmission cable; the cover is arranged on a first face of the main body different from a second face of the main body on which the cover opening pedal and the force transmission cable are arranged; the main body comprises at least locally at the face receiving the cover opening pedal an internal wall of the voluntary contribution container, an external wall removable from the main body being attached to the main body so as to delimit with the internal wall a technical volume in which at least part of the cover opening device is housed;the lid opening device comprises at least one actuating bar connected to the lid opening pedal and on which the force transmission cable is fixed, the actuating bar being rotatable, the lid opening device being configured so that an actuation of the lid opening pedal causes traction of the force transmission cable on the lid by rotation of the actuating bar; the lid opening pedal is rotatable about a first axis of rotation, the actuating bar being rotatable about a second axis of rotation perpendicular to the first axis of rotation; the actuating bar is rotatable about a first of its two ends, the force transmission cable being fixed to the actuating bar in an area located between a second end of the actuating bar and the middle of the actuating bar;the lid opening device comprises a connecting element fixed to the lid opening pedal and to the actuating bar, the connecting element being configured to convert a movement of the lid opening pedal into a rotation of the actuating bar; the connecting element is formed by a connecting rod comprising two ends fixed respectively to the lid opening pedal and to the actuating bar, the attachment of the connecting rod to the lid opening pedal and to the actuating bar being carried out by a connecting member allowing at least one degree of freedom in rotation of the connecting rod relative to the lid opening pedal and to the actuating bar;the connecting element is formed by a movable element, for example a jack, movable between a retracted position and a deployed position, the movable element being configured to: ∘ Remain in the retracted position and convert a movement of the lid opening pedal into a rotation of the actuating bar when a force exerted on the lid opening pedal is less than a predetermined value, or ∘ Move from the retracted position to the deployed position concomitantly with a movement of the lid opening pedal when a force exerted on the lid opening pedal is greater than the predetermined value; the connecting element is fixed to the actuating bar in an area located between the first end of the actuating bar and the middle of the actuating bar; the lid opening device comprises at least one member for returning the lid opening pedal to the rest position;the return member of the lid opening pedal to the rest position comprises a return spring connecting the actuating bar to a stationary support of the actuating bar; one end of the force transmission cable connected to the lid passes through the lid in its thickness from a first face of the lid, the end of the force transmission cable comprising an end piece configured to be placed in abutment against a second face of the lid without being integral with the lid; and the lid opening pedal is movable between two stops, each stop being formed by a buffer, for example a rubber buffer.

Detailed description

[0012] We now refer to the figure 1illustrating a voluntary waste contribution container 2 (hereinafter referred to as “container 2”) comprising a main body 6, a cover 3 closing an opening for introducing waste (not visible on the figure 1 ).

[0013] A voluntary waste drop-off container is a container placed in a given location, for example defined by a community, and accessible to a group of people, for example residents, to allow them to deposit their waste in the container. These may be overhead voluntary waste drop-off columns, for example including emptying hatches on the lower face of the drop-off column, or large-volume containers.

[0014] As can be seen on the figures 2 And 3 illustrating a part of the container 2, the latter comprises a lid opening device 4 according to the invention.

[0015] The main body 6 forms a waste collection volume. The latter can be formed of several faces (7, 7', 7" and 7'" on the figure 1 ) connected to each other and whose number is variable.

[0016] The container 2 also comprises one or more waste introduction openings, one or more covers closing the openings (one cover per opening), the cover 3 being rotatable between a position closing the waste introduction opening and a maximum open position in which the waste introduction opening is accessible to a user.

[0017] The lid opening device 4 comprises a lid opening pedal 8 (hereinafter referred to as “pedal 8”) arranged on one face of the main body 6 as can be seen in the figures 2 And 3. The pedal 8 is movable between a rest position and an activation position in which the cover 3 is open. The figures 2 And 3 illustrate respectively the rest position and the activation position of the pedal 8. In the illustrated example, the pedal 8 is movable in rotation relative to the main body 6 by being fixed to perforated slides 10 by cylindrical lugs. The lowering of the pedal 8 leads to an opening of the cover by, as described below, transmission of forces by at least one force transmission cable 12. The pedal 8 could also be movable in translation by being for example mounted to slide along lateral slides.

[0018] As mentioned above, the lid opening device 4 comprises at least one force transmission cable 12 (hereinafter referred to as “cable 12”, two cables 12 in the illustrated example) connecting the pedal 8 to the lid, the lid opening device 4 being configured so that actuation of the pedal 8 causes the lid 3 to open by pulling the cable(s) 12 on the lid 3. In other words, and in the illustrated example, lowering the pedal 8 leads to pulling the cables 12 downwards, the cables 12 being connected to the lid 3 so as to pivot it to release the waste introduction opening. This force transmission can be carried out using a special architecture, visible on the figures 2 And 3 and described below, or by direct attachment of the cable(s) 12 to the pedal 8 and to the cover.

[0019] The cable(s) 12 are arranged on the same face of the main body 6 as the pedal 8 to obtain the advantages mentioned above. They can, in a fairly conventional manner, be arranged in a sheath, which facilitates their placement and movement, and ensures compact protection of the latter. The attachment to the cover 3 is chosen so as to ensure the rotation of the latter when stressed by the cable(s) 12. It is possible to provide that the cover 3 comprises an axis of rotation with a distal part (i.e., moving furthest from the container 2 when the cover 3 rotates) on one side of the axis of rotation and a proximal part (i.e., moving least away from the container 2 when the cover 3 rotates) on one side of the axis of rotation. The cable(s) 12 can be connected to the proximal part so as to pull it when the pedal 8 is lowered.This traction leads to a lowering of the proximal part of the cover which will therefore pivot and open, causing the distal part of the cover 3 to move away from the main body 6.

[0020] The main body 6 may include, as is the case on the figures 1 to 3 , at least locally at the level of the face receiving the pedal 8, an internal wall 9 of the container 2, an external wall 5 (visible on the figure 1) removable from the main body 6 and being attached to the main body 6 so as to delimit with the internal wall 9 a technical volume in which at least part of the device for opening the cover 4 is housed. Thanks to this configuration, the device for opening the cover is at least partly arranged in a housing protecting it from potential external damage but also from the waste present in the container 2. This is done by using a part of the main body 6 (the internal wall 9 being able to form an entire interior part of the main body 6, for example to ensure sealing of the latter, or be smaller) as part of the housing, which reduces the number of parts to be added.Finally, this arrangement allows easy access to the device for opening the cover 4 from outside the container 2 by simply removing the external wall 5, which can be likened to a hood, even if the container 2 contains waste, because it is not necessary to access the waste storage volume to access the device for opening the cover.

[0021] The cover 3 can be arranged on the same face of the main body 6 as the pedal 8 and the cable(s) 12. This makes it possible to obtain a compact cover opening system, the entire cover being accessible by dismantling the external wall 5. Alternatively, the cover 3 can be arranged on a different face of the main body 6 from the pedal 8 and the cable(s) 12. This demonstrates the freedom offered in the positioning of the cover 3 relative to the pedal 8 and the cables 12 while retaining the other advantages associated with the invention.

[0022] The lid opening device 4 may comprise at least one intermediate element arranged between the cable(s) 12 and the pedal 8. It is for example possible to provide the presence of at least one actuating bar 14 connected to the pedal 8 and on which the cable(s) 12 are fixed, the actuating bar 14 being movable in rotation, the lid opening device 4 being configured so that an actuation of the pedal 8 causes a traction of the cable(s) 12 on the lid 3 by rotation of the actuating bar 14. The implementation of an intermediate rotating element, such as for example the intermediate bar 14, makes it possible to vary the stroke of the pedal 8 while obtaining an unchanged opening of the lid 3, or to vary the level of opening of the lid 3 while maintaining an unchanged stroke of the pedal 8, by modifying the position of attachment of the cable(s) 12 on the intermediate element, here the actuating bar 14.Examples of implementation demonstrating this possibility will be given later.

[0023] Preferably, the pedal 8 is movable in rotation along a first axis of rotation B visible on the figure 2 , the actuating bar 14 being movable in rotation along a second axis of rotation C visible on the figure 1 and perpendicular to the first axis of rotation. Such an arrangement makes it possible to double the rotations and therefore the possibility of varying the stroke of the pedal 8 while obtaining an unchanged opening of the cover 3, or of varying the level of opening of the cover 3 while maintaining an unchanged pedal stroke.

[0024] As can be seen on the figures 2 And 3, the actuating bar 14 can be movable in rotation around a first of its two ends (here a first end 16), the cable(s) 12 being fixed on the actuating bar 14 in a zone situated between a second end 18 and the middle of the actuating bar 14 (a separation axis A allows on the figures 2 And 3 to visualize the middle of the actuating bar 14). In this case, a slight rotation of the actuating bar 14 allows a greater stroke of the cables 12 and therefore a significant opening of the cover.

[0025] In order to vary the travel of the pedal 8 while obtaining an unchanged opening of the cover 3, or to vary the level of opening of the cover 3 while maintaining an unchanged travel of the pedal, an optimal balance can be found by choosing the positioning of the cable(s) 12 on the actuating bar 14. As will be described, this choice also involves consequences in terms of force to be applied to the pedal 8 to open the cover 3. A positioning distant from the axis of rotation of the actuating bar 14 makes it possible to obtain a limited travel of the pedal 8 for a complete opening of the cover 3 (or a greater opening of the cover 3 for the same travel of the pedal 8), because a small rotation of the intermediate bar 14 leads to an increasingly significant displacement of the latter as one moves away from the first end 16 towards the second end 18.On the other hand, the force to be exerted on the pedal 8 to open the cover 3 will also be greater. Conversely, positioning the cable(s) 12 close to the axis of rotation of the actuating bar 14 does not make it possible to significantly reduce the travel of the pedal 8 for a complete opening of the cover 3 (or to obtain a greater opening of the cover 3 for the same travel of the pedal 8), but the force to be produced on the pedal 8 to open the cover 3 is less important.

[0026] As can be seen on the figures 2 And 3, the device for opening the cover 4 may comprise a connecting element fixed to the pedal 8 and to the actuating bar 14, the connecting element being configured to convert a movement of the pedal 8 into a rotation of the actuating bar 14. This use makes it possible to add an additional adjustment in the balance sought between the amplitude of the travel of the pedal 8 relative to the opening of the cover 3 (and in the determination of the force to be applied to the pedal 8 to open the cover 3) mentioned above.

[0027] The example of figures 2 And 3illustrates a connecting element formed by a connecting rod 20 comprising two ends fixed respectively to the pedal 8 and to the actuating bar 14, this fixing being carried out by a connecting member allowing at least one degree of freedom in rotation of the connecting rod 20 relative to the pedal 8 and to the actuating bar 14. It may for example be a ball joint type connection.

[0028] The connecting rod 20 can be fixed on the actuating bar 14 in an area located between the first end 16 and the middle of the actuating bar 14, illustrated by the separation axis A. Such an arrangement allows, by a small movement of the pedal 8, to move the second end 18 of the actuating bar 14 by a significant amplitude, and therefore to open the cover 3 by a large opening amplitude (and with a greater force to be exerted on the pedal 8). Conversely, and if the connecting rod 20 is fixed in an area located between the second end 18 and the middle of the actuating bar 14, such an arrangement requires a greater movement of the pedal 8 to move the second end 18 of the actuating bar 14 by a significant amplitude, and to open the cover 3 by a large opening amplitude (but with a lesser force to be exerted on the pedal 8).This is once again an adjustment between, on the one hand, the reduction in the travel of the pedal 8 (or the increase in the opening of the cover 3) and, on the other hand, the force to be exerted on the latter to open the cover 3. By combining this possibility of adjustment with the choice of the position of attachment of the cable(s) 12 on the actuating bar 14, this allows a fine adjustment of the kinematics of opening the cover 3.

[0029] The connecting element can advantageously be formed by a mobile element such as a jack. The latter is by default in the retracted position, that is to say in a position corresponding to a closed state of the cover 3 as well as to a raised state (i.e. rest) of the pedal 8. This mobile device, for example a jack, is sized and / or positioned on the actuating bar 14 so as to: Remain in the retracted position when the pedal 8 is pressed by a user, leading to the opening of the cover 3. In such a configuration, the movable element simply transmits the movement of the pedal 8 to the actuating bar 14 to allow the cover 3 to be opened. The dimensioning of the movable element is such that the force required to move the pedal 8 to open the cover 3 is less than the deployment force of the movable element. Extend from the retracted position to a deployed position in the event of the cover 3 being blocked from opening, for example if the latter is equipped with a locking system in the locked position.Thus, the movable element extends to allow movement of the pedal 8 when a force greater than a predetermined value (and corresponding to the force allowing deployment of the movable element) is exerted on the pedal 8 and this without movement of the actuating bar 14 and therefore of the cover 3. This makes it possible to avoid any breakage of the cover opening device 4 in the event of strong stress on the pedal 8 when opening of the cover is impossible. Therefore, the force necessary for deployment of the movable element is less than the resistance to breakage of the elements forming the cover opening device 4.

[0030] Advantageously, the device for opening the cover comprises at least one member for returning the pedal 8 to the rest position, for example a spring deformed when pressure is exerted on the pedal 8 and returning to a rest position by returning the pedal 8 to the rest position. This can allow, depending on the positioning of the return member, an opening of the cover 3 without a lowering movement of the pedal 8, which can in particular block a foot of a user who has opened the cover with his hand. Indeed, such an opening leads to a relaxation of the cable(s) 12, the latter not exerting any force on the pedal 8 which remains in position thanks to the return means.

[0031] As can be seen on the figure 4, the return member may take the form of a return spring 30 connecting the actuating bar 14 and a support 32 of the actuating bar, this support 32 being stationary. The support 32 may be an element attached to the internal wall 9, or be the internal wall 9 itself. Lowering the pedal 8 leads to an extension of the return spring 30 by lowering the actuating bar 14 following the movement of the pedal 8 and allowing the opening of the cover 3. When the pressure on the pedal 8 stops, the return spring 30 returns the actuating bar 14 to the rest position near the support 32 by its retraction, which leads to a raising of the pedal 8 which returns to the rest position and to a closing of the cover 3.The return force and the positioning of the return spring 30 are chosen so as to obtain a desired effect at the level of the authorized travel for the actuating bar 14 and the pedal 8, the force necessary to open the cover 3 by actuation of the pedal 8, etc.

[0032] Advantageously, and as illustrated in the Figure 5, One end 22 of the cable(s) 12 is connected to the cover 3 by passing through the latter in its thickness from a first face 24 of the cover 3, the end 22 comprising an end piece 26 configured to be placed in abutment against a second face 28 of the cover 3 without being integral with the cover 3. Such a configuration makes it possible, in the context of a possibility of movement of the cover 3 by hand, to ensure that the cable does not follow the movement of the cover moved by hand by a user, and therefore to limit the movement of the cable(s) 12 when a movement of the cover is not induced by a movement of the pedal 8.

[0033] Advantageously, and as can be seen on the figure 4 , the pedal 8 is movable between two stops. Each stop can be formed by a buffer 34 which can be fixed on the slides 10, for example a rubber buffer. List of references
