Description

DESCRIPTION Title of the invention: Electromechanical locking device for collective waste container

[0001] The invention relates to an access control device for a waste container.

[0002] In the field of waste collection, the use of waste containers such as voluntary contribution containers installed in collection areas to allow users to deposit their waste is known. Such a waste collection device typically comprises a container that can be buried over its entire height, and a terminal that emerges from the ground for the introduction of waste. The terminal has an opening door, a door opening handle that operates the opening or closing of the door thanks to a dedicated kinematic interposed and functionally connected to the handle and the door.

[0003] In order to ensure better control of the volume of waste produced and to encourage users to sort their waste, it is known to install access control on waste containers to authorize or not the deposit of waste depending on authorizations granted to users and to record the deposits made by each user.

[0004] Typically, these access control devices include a badge reader. When a user wishes to deposit waste, they present a badge to the badge reader, and the access control device then queries a database, usually remote, via a telecommunications network, to determine whether or not the user is authorized to deposit their waste.

[0005] Another known method is to write a predetermined sector code into the memory of the access control device, authorization then being granted to any user presenting a badge with this sector code.

[0006] However, one problem concerns the integration of access control on existing waste containers.

[0007] Indeed, there are a large number of containers deployed today that do not have an access control solution. However, it would be useful to be able to equip with an access control device without the need to replace the entire container.

[0008] This is why there is a need for a solution to equip existing waste containers, but not yet equipped with an access control system.

[0009] Furthermore, it has been observed that in traditional waste collection devices, the actuation functions, for example of the terminal opening door, are normally carried out manually by humans or require complex and expensive power supplies. It is also necessary for these doors to ensure controlled access of waste into the container, to prevent undue and / or improper use of the waste collection device by unauthorized persons.

[0010] Even more so in this case, with the increase in waste collection devices of components or elements that require an electrical power supply, it is necessary to emphasize the need to equip these devices with simple electrical power supply systems that do not involve high energy consumption.

[0011] The invention aims to overcome all or part of the problems mentioned above by proposing a device for collecting waste equipped with a locking and unlocking system on the collective container terminal allowing the door of the container terminal to be partially locked after use so as to force the user of the container to present an authorized individual means of identification, such as a badge, a card, a mobile phone or any other electronic and / or mechanical device paired with the locking / unlocking system as is known in the technical field. This partial locking thus has the advantage of only allowing one opening per use, even when the door of the terminal is not perfectly closed by the previous user, and therefore preventing any illegitimate user from opening the door of the container terminal without a means of identification.

[0012] To this end, the invention relates to a device comprising a collection terminal capable of being associated with a container, the terminal comprising: - a door allowing the introduction of waste into the terminal, the door being able to pass into an open configuration allowing the introduction of waste into the terminal and in a closed configuration preventing the introduction of waste into the terminal, - an electrically actuated door locking device, the locking device being configured to swing the door from the open configuration to the closed configuration and vice versa, and configured to swing the door into an intermediate configuration between the open configuration and the closed configuration, the door locking device being configured to prohibit a swing between the intermediate configuration and the open configuration, the locking device comprising: - A chassis, - A double-track cam connected by a first pivot link to the chassis and configured to perform a rotational movement according to a predefined stroke, - A locking support connected according to a second pivot connection to the chassis, comprising a first cam follower, the locking support being configured to rotate according to a first direction of rotation when a first track of the double-track cam is in contact with the first cam follower, - A plate connected by a third pivot connection to the chassis, comprising a second cam follower, the plate being configured to rotate in a second direction of rotation, opposite to the first direction of rotation when a second track of the double-track cam is in contact with the second follower, the plate also being configured to drive the locking support in rotation in the second direction of rotation, the locking support also comprising a door locking finger capable of being inserted, in the closed configuration, into the door.

[0013] According to one aspect of the invention, the second pivot link and the third pivot link have the same axis of rotation.

[0014] According to one aspect of the invention, the second pivot link and the third pivot link are dissociated.

[0015] According to one aspect of the invention, the locking support comprises a first pressure means configured to exert on the locking support a force in a direction opposite to the first direction of rotation.

[0016] According to one aspect of the invention, the plate comprises a second pressure means configured to exert on the plate a force in a direction opposite to the second direction of rotation.

[0017] According to one aspect of the invention, the locking device comprises a control configured to control the rotation of the dual-track cam.

[0018] According to one aspect of the invention, the device comprises a device for angular monitoring of the double-track cam and / or the plate and / or the locking support.

[0019] According to one aspect of the invention, the locking device is positioned against the door of the collection terminal.

[0020] According to one aspect of the invention, the locking finger comprises a beveled end.

[0021] According to one aspect of the invention, the first pressure means is a spring.

[0022] According to one aspect of the invention, the second pressure means is a spring.

[0023] The invention also relates to a method for unlocking and locking a collection terminal door capable of being associated with a container and a locking device comprising the following steps: - Rotation of the double-track cam according to the first direction of rotation to a first cam position defining a stop position of the locking support so as to generate the open configuration of the door, - Rotation of the double-track cam in the second direction of rotation to a second cam position defining a stop position of the plate so as to generate the closed configuration of the door, - Rotation of the double-track cam between the first cam position and the second cam position defining a rest position of the locking support and the rest position of the plate so as to generate the intermediate configuration of the door.

[0024] The invention will be better understood and other advantages will appear on reading the detailed description of an embodiment given by way of example, a description illustrated by the attached drawing in which:

[0025] [Fig.1] Figure 1 shows a perspective view of a waste container in the open position on which a locking device according to the invention is mounted;

[0026] [Fig.2] Figure 2 represents a perspective view of the locking device according to the invention in a closed configuration;

[0027] [Fig.3] Figure 3 represents a perspective view of the locking device according to the invention in an open configuration;

[0028] [Fig. 4] Figure 4 represents a perspective view of the locking device according to the invention in an intermediate configuration;

[0029] [Fig.5] Figure 5 represents a schematic view of a method for unlocking and locking a collection terminal door according to the invention.

[0030] For the sake of clarity, the same elements will have the same references in the different figures.

[0031] Figure 1 shows a device for collecting waste 1 which comprises a container 2 buried over its entire height. Such a waste collection device 1 also comprises a terminal 3 for dumping the waste.

[0032] Alternatively, container 2 is partially buried or placed on the ground.

[0033] Terminal 3 of waste collection device 1 comprises a drum opening member 30.

[0034] This drum 30 has two walls 301, 302 in the form of a cylinder truncated and which are hinged relative to each other so that in the open position, it is possible to insert waste into the terminal 3 and into the container 2.

[0035] A cylinder truncated shape is understood to mean a wall of generally cylindrical shape, but not closed, in other words a cylindrical body which would be formed by an incomplete revolution, less than 2TT, for example between TT and 4TT / 3, in other words forming a portion of cylinder going from 1 / 2 cylinder to 2 / 3 cylinder.

[0036] But the invention is not limited to these cylinder truncated values, the only criterion being that the cylinder portions must not be closed.

[0037] We distinguish the external wall 301 and the internal wall 302: the external walls 301 and internal walls 302 being shaped to form two superimposable layers.

[0038] In the open position, the two external walls 301 and internal 302 form an insertion mouth 304, allowing waste to be poured into terminal 3.

[0039] In the closed position, the two external walls 301 and internal 302 form an emptying mouth, substantially opposite the insertion mouth 304 relative to the axis of rotation of the drum, allowing the waste to fall from the drum 30 into a storage part 20 of the container 2.

[0040] The articulation of the two outer walls 301 and inner walls 302 of the drum 30 is carried out so that the insertion mouth 304 and the emptying mouth are never open at the same time. Either the outer walls 301 and inner walls 302 are arranged, by their respective articulation, so as to form the insertion mouth 302, or they form the emptying mouth.

[0041] However, it may be envisaged, according to a variant, that the opening member 30 is a sliding door allowing waste to be inserted into the terminal 3 and into the container 2. Therefore, the insertion mouth and the emptying mouth are combined. According to another variant, the opening member 30 is a single-leaf door, thus allowing waste to be inserted into the terminal 3 and into the container 2. In a configuration of use of a single-leaf door, it is possible to dissociate the insertion mouth and the emptying mouth and therefore in the open position of the single-leaf door, the insertion mouth is accessible. And, when the single-leaf door is in the closed position, the emptying mouth is accessible.

[0042] Therefore, in the remainder of the description, the opening member 30 is considered to be a door 30.

[0043] Thus, the device 1 for collecting waste comprises the collection terminal 3 associated with the container 2 and the terminal 3 comprises the door allowing the introduction of waste into the terminal. The door 30 is capable of passing into an open configuration allowing the introduction of waste into the terminal 3 and into a closed configuration preventing the introduction of waste into the terminal 3.

[0044] In order to operate the door 30 and to make it switch from the closed configuration to the open configuration and vice versa, the collection device 1 also comprises an electrically actuated door 30 locking device 4. The device lock 4 is configured to switch the door from the open configuration to the closed configuration and vice versa, and configured to switch the door to an intermediate configuration between the open configuration and the closed configuration.

[0045] The intermediate configuration can be likened to a security configuration which prevents the door 30 from reopening immediately so as to force the user to identify himself again by badge-in, for example, to unlock the door 30 without forcing the door 30 to swing until it is completely closed.

[0046] Furthermore, the intermediate configuration also has the advantage of allowing partial closing of the door 30 to prevent any introduction of waste while delimiting a sufficient space so that the user does not injure himself when closing the door by pinching his fingers for example.

[0047] To do this, the locking device 4 of the door 30 is configured to prohibit a switch from the intermediate configuration to the open configuration.

[0048] The locking device 4, shown in Figure 2, comprises: - A frame 40. The frame 40 ensures the fixing of the locking device 4 against the waste collection device 1. The frame 40 has, in a preferred configuration, shown in figure 2, a housing shape which is immobile relative to the collection device 1. - A double-track cam 42 connected by a first pivot link 420 to the chassis 40 and configured to perform a rotational movement according to a predefined stroke. The double-track cam 42 is therefore configured to perform a rotational movement in a trigonometric direction and in an anti-trigonometric direction relative to the chassis. - A locking support 44 connected according to a second pivot connection 440 to the frame 40 which comprises a first cam follower 442 capable of interacting with a first track 422 of the double-track cam 42. Indeed, the locking support 44 is configured to rotate in a first direction of rotation when the first track 422 of the double-track cam 42 is in contact with the first cam follower 442. According to the example of FIG. 2, the first direction of rotation is the anti-trigonometric direction. In the following the description, the first direction of rotation is assimilated to the anti-trigonometric direction. Thus, when the double-track cam 42, by rotating in the trigonometric direction, comes into contact, via the first track 422, with the locking support 44, via the first cam follower 442, the double-track cam 42 drives the locking support 44 in rotation in the anti-trigonometric direction. This driving of the locking support 44 can be assimilated to the open configuration of the door, as shown in Figure 3.

[0049] The locking device 4 also comprises, as shown in FIG. 2, a plate 46 connected by a third pivot connection 460 to the chassis 40. The plate 46 comprises a second cam follower 426 and is configured to rotate in a second direction of rotation, opposite to the first direction of rotation, that is to say in the preferred case the trigonometric direction, when a second track 424 of the double-track cam 42 is in contact with the second cam follower 426. In the remainder of the description, the second direction of rotation is assimilated to the trigonometric direction. In other words, when the double-track cam 42, by rotating in the anti-trigonometric direction, comes into contact, via the second track 424, with the plate 46, via the second cam follower 464, the double-track cam 42 drives the plate 46 in rotation in the trigonometric direction.This drive of the plate 46 can be likened to the closed configuration of the door, as shown in Figure 2.

[0050] The plate 46 is also configured to drive the locking support 44 in rotation in the second direction of rotation, namely the trigonometric direction, so as to make it possible to obtain the closed configuration of the door 30.

[0051] The locking support 44 also includes a door locking finger 444 adapted to be inserted, in the closed configuration of FIG. 2, into the door 30.

[0052] Alternatively, the dual-track cam 42 may be replaced by two single-track cams, one single-track cam interacting only with the locking bracket 44 and a second single-track cam interacting only with plate 46. The pivot links of each of the single track cams can be combined or separated.

[0053] Therefore, the use of a double-track cam 42 and a plate 46 has the advantage of generating the mobility of the locking support 44, which represents the locking member of the door 30, in both directions of rotation, namely the trigonometric direction by means of the cam 42 and the anti-trigonometric direction by means of the plate 46.

[0054] According to a preferred configuration, the second pivot connection 440 and the third pivot connection 460 have the same axis of rotation, as shown in Figure 2. This arrangement has the advantage of being compact and of limiting the number of components in the locking device 4.

[0055] According to another configuration, the second pivot connection 440 and the third pivot connection 460 are dissociated. This dissociation has the advantage of improving the reliability of the locking support 44 and the plate 46 since in the event of a malfunction of the second pivot connection 440, the plate 46 is not impacted. And, similarly, in the event of a malfunction of the third pivot connection 460, only the plate 46 is impacted and the locking support 44 is not, for its part, impacted in its rotation.

[0056] In one configuration, the locking support 44 also comprises a first pressure means 446 configured to exert on the locking support 44 a force in the direction opposite to the first direction of rotation. In other words, the first pressure means 446 exerts a restoring force on the locking support 44 in the direction opposite to the rotation generated by the interaction between the double-track cam 42 and the locking support 44. Thus, the first pressure means 446 generates a restoring force in the trigonometric direction. In this way, the first pressure means 446 has the advantage of being able to maintain the locking support 44 in a rest position when the double-track cam 42 is not in contact with the locking support, as shown in FIG. 2.

[0057] Thus, Figure 2 represents the locking device 4 when the door 30 is in the closed configuration. In this closed configuration, the interactions between the components present in the locking device 4 are as follows: - The double-track cam 42 bears against the plate 46 via the second track 424 and the second cam follower 426 so as to induce a rotation of the plate 46, in the trigonometric direction, to a stop position against the chassis 40. - The locking support 44 is left free, that is to say it is distant from the double-track cam 42. From then on, it is the first pressure means 446 which generates a return force on the locking support 44 so as to induce a rotation in the trigonometric direction to the rest position of the locking support 44, as shown in figure 2. The rest position of the locking support 44 coincides with the stop position of the plate 46.

[0058] The locking finger 444 is thus introduced into a complementary locking device 32 making it possible to induce locking of the door 30 in the closed configuration. This complementary locking device 32 is for example a cavity complementary to the locking finger 444 arranged on the terminal 3.

[0059] Therefore, the rest position of the locking support 44 can be interpreted as the position of the locking support 44 in abutment against the plate 46 when the plate 46 is, itself, in the abutment position imposed by the double-track cam 42.

[0060] According to a variant, the complementary locking device of the locking finger 444 is a stop or a protrusion arranged so as to prevent any movement of the door 30 in a direction, axial or rotational, allowing the opening of the door 30.

[0061] According to one configuration, the plate 46 comprises a second pressure means 466 configured to exert on the plate 46 a force in the direction opposite to the second direction of rotation. In other words, the second pressure means 466 exerts a restoring force on the plate 46, in the direction opposite to the rotation generated by the interaction between the double-track cam 42 and the plate 46. Thus, the second pressure means 466 generates a restoring force in the anti-trigonometric direction. In this way, the second pressure means 466 has the advantage of being able to maintain the plate 46 in a rest position when the double-track cam 42 is not in contact with plate 46, as shown in Figure 3.

[0062] Thus, Figure 3 shows the locking device 4 when the door 30 is in the open configuration. In this open configuration, the interactions between the components present in the locking device 4 are as follows: - The double-track cam 42 bears against the locking support 44 via the first track 422 and the first cam follower 442 so as to induce a rotation of the locking support 44, in the anti-trigonometric direction, to a stop position against the chassis 40, as shown in FIG. 3. - The plate 46 is left free, that is to say that the plate 46 is distant from the double-track cam 42. From then on, it is the second pressure means 466 which generates a return force on the plate 46 so as to induce a rotation in the anti-trigonometric direction until the rest position of the plate, as shown in figure 3.

[0063] Furthermore, the locking finger 444 also undergoes this rotation in the anti-trigonometric direction so as to no longer interact with the complementary locking device 32 and be freed from its influence. The door 30 can then be unlocked by the user in the open configuration.

[0064] In the intermediate configuration, shown in Figure 4, the double-track cam 42 is distant from the locking support 44 and the plate 46.

[0065] Therefore, it is the first pressure means 446 which exerts a restoring force on the locking support 44 so as to induce a rotation in the trigonometric direction. And, similarly, the second pressure means 466 exerts a restoring force on the plate 46 so as to induce a rotation of the plate in the anti-trigonometric direction. The plate 46 is then in the rest position.

[0066] And, the locking support 44 is then in a partial rest position, as shown in FIG. 4, in which the locking support 44 is in abutment against the plate 46 while the plate 46 is, itself, in the rest position. The partial rest position is an angular position between the rest position of the locking support 44 and the abutment position of the locking support 44 imposed by the double-track cam 42.

[0067] As a result, the locking finger 444 is partially interacting with the complementary locking device 32. In other words, the locking finger 444 is partially introduced into the complementary locking device 32. This partial introduction of the locking finger 444 into the complementary locking device 32 is sufficient to induce locking of the door 30, although the door is not in the closed configuration. The door is then in the intermediate configuration.

[0068] In order to facilitate the at least partial introduction of the locking finger 444 into the complementary locking device 32, the locking finger comprises, at its end interacting with the complementary locking device 32, a beveled end 444'. More precisely, the locking finger 444 is partially beveled, along one half of the section forming the locking finger 444. Thus, the locking finger 444 can be introduced more easily into the complementary locking device 32 while preventing reopening of the door 30.

[0069] In this preferred configuration, the locking device 4 is positioned against the door 30 of the collection terminal 3 and the complementary locking device 32 is arranged against the terminal 3 opposite the locking device 4.

[0070] According to one configuration, the second pressure means 466 exerts on the plate 46 a return force in the anti-trigonometric direction whose force modulus is greater than or equal to the force modulus of the return force exerted by the first pressure means 446 on the locking support 44. This configuration has the advantage of allowing the plate 46 to resist the rotation induced by the locking support 44 and by the first pressure means 446.

[0071] According to a preferred configuration, the modulus of the restoring force of the second pressure means 466 is strictly greater than the modulus of the restoring force of the first pressure means 446.

[0072] According to a preferred configuration of the invention, the first pressure means 446 is a torsion spring. And, similarly, the second pressure means 466 is a torsion spring.

[0073] However, any other means of inducing a restoring force can be considered, such as a helical spring or even magnetic resistance.

[0074] In order to induce a rotation of the double-track cam 42 in the trigonometric direction or in the anti-trigonometric direction, the locking device 4 comprises a control 45 configured to control the rotation of the double-track cam 42, as shown in figures 2 to 4. The control 45 is, for example, a servomotor.

[0075] Alternatively, any type of command allowing the generation of a binary command in order to induce a rotation of the double-track cam 42 in the trigonometric direction or in the anti-trigonometric direction can be envisaged.

[0076] Furthermore, the locking device 4 may comprise an angular monitoring device 47 of the cam 42 and / or the plate 46 and / or the locking support 44. The angular monitoring device 47 consists of at least one angular sensor 470 and, in one configuration, three angular sensors 470, 471 and 472. A first angular sensor 470 is positioned so as to detect when the plate 46 enters the stop position of the plate 46 imposed by the double-track cam 42, as shown in FIG. 2. A second angular sensor 471 is positioned so as to detect when the locking support 44 enters the rest position of the locking support 44 as shown in FIG. 2. A third angular position sensor 472 is positioned so as to detect when the locking support 44 enters the stop position imposed by the double-track cam 42, as shown in FIG. 3.

[0077] The first, second and third angular sensors 470, 471 and 472 are binary detection sensors. Thus, the first angular sensor 470 can only indicate whether the plate 46 is in the stop position or not, the second angular sensor 471 can only indicate whether the locking support 44 is in the rest position or not and the third angular sensor 472 can only indicate whether the locking support 44 is in the stop position or not.

[0078] Therefore, if, simultaneously, the first angular sensor 470 detects that the plate 46 is in the stop position of the plate 46 and the second angular sensor 471 detects that the locking support 44 is in the rest position of the locking bracket 44, and the third angular sensor 472 does not indicate that the locking bracket 44 is in the stop position of the locking bracket 44, then the door 30 is in the closed configuration.

[0079] If, simultaneously, the first angular sensor 470 does not indicate that the plate 46 is in the stop position of the plate 46, the second angular sensor 471 does not indicate that the locking support 44 is in the rest position of the locking support 44, and the third angular sensor 472 detects that the locking support 44 is in the stop position of the locking support 44, then the door 30 is in the open configuration.

[0080] And, if, simultaneously, the first angular sensor 470 does not indicate that the plate 46 is in the stop position of the plate 46, the second angular sensor 471 detects that the locking support 44 is in the rest position of the locking support 44, and the third angular sensor 472 does not indicate that the locking support 44 is in the stop position of the locking support 44, then the door 30 is in the intermediate configuration.

[0081] Furthermore, it is also possible to detect a switch between two configurations among the closed, open and intermediate configurations, the switch between the intermediate configuration and the open configuration being prohibited unless the user is identified, in particular when, simultaneously, the first angular sensor 470 does not indicate that the plate 46 is in the stop position of the plate 46, the second angular sensor 471 does not indicate that the locking support 44 is in the rest position of the locking support 44, and the third angular sensor 472 does not indicate that the locking support 44 is in the stop position of the locking support 44, then the door 30 is in the intermediate configuration.

[0082] The monitoring device 47 has the advantage of allowing the user to view the configuration in which the door 30 is located while viewing the operational state of the components of the locking device 4 such as the plate 46 or the locking support 44.

[0083] Another angle sensor can be introduced into the control 45 so as to detect the angle of rotation of the double-track cam 42 providing further information on the operational status of the components of the locking device 4 and particularly of the double-track cam 42.

[0084] Furthermore, the angular monitoring device also has the advantage of being able to identify a malfunction of the locking device 4 and to target the component among the locking support 44, the plate 46 or the cam 42, of the defective locking device.

[0085] Indeed, any other combination of detection of the first, second and third angular sensors 470, 471 and 472 indicates a malfunction of the locking device 4.

[0086] It should be noted that it may be considered to reverse the positioning of the locking device 4 and the complementary locking device 32. In fact, the locking device 4 may be positioned against the terminal 3 and the complementary locking device 32 may be positioned against the door 30 opposite the locking device 4.

[0087] The invention also aims to propose, as shown in Figure 5, a method 1000 for unlocking and locking a door 30 of a collection terminal 3 capable of being associated with a container 2 and a locking device 4 comprising the following steps: - Rotation (step 1001) of the double-track cam 42 in the first direction of rotation, namely the anti-trigonometric direction, to a first cam position defining the stop position of the locking support 44 so as to generate the open configuration of the door 30, - Rotation (step 1002) of the double-track cam 42 in the second direction of rotation, namely the trigonometric direction, to a second cam position defining the stop position of the plate 46 so as to generate the closed configuration of the door 30, - Rotation (step 1003) of the double-track cam 42 between the first cam position and the second cam position defining the rest position of the locking support 44 and the rest position of the plate 46 so as to generate the intermediate configuration of the door 30.
