Definitions

  • the present disclosure relates to a mechanism for unlocking and locking a swing lid of an urban waste container that allows or prevents swing of the container lid so as to control access to the interior of the container.
  • the present disclosure further relates to an urban waste container comprising such mechanism for unlocking and locking the container lid.
  • the unlocking and locking mechanism disclosed herein is also applicable to a wide range of other different types of containers.
  • Urban waste containers known to date comprise a body whose interior is adapted to receive urban waste therein and at least one swing lid mounted thereon to prevent or allow access to the interior of the container.
  • the lid in known containers can be operated manually or by means of a pedal and/or a lever that is arranged outside of the container which acts on an actuating mechanism that causes the lid to swing to gain access to the inside of the container.
  • a mechanism for unlocking and locking the lid may be also provided.
  • ES1213884 discloses an actuating mechanism for a swing lid of a waste container.
  • the lid of the container is associated with an opening and closing cam that is driven by an electric motor.
  • a control unit associated with an electric power supply, controls the electric motor which is activated by a push button, a foot pedal, a presence sensor, or a card reader.
  • ES1233562U discloses a waste container comprising a container body and a pivoting loading cover.
  • a locking arm is fixed to an end of a cover shaft.
  • a control member is articulated to the locking arm and pivotable between a release and locking positions.
  • the control member has a blocking element so that when held in a retention stop with the locking arm in a closed position and the control member is in a locked position the loading cover is locked in a closed position.
  • An electric actuator is provided having a moving member arranged. When the moving member is activated in a locking direction, it is moved to an extended position interfering with the control member and moving it from the release to the locking position. When the moving member is activated in a release direction, it is moved to a retracted position allowing the control member to be returned back to the release position allowing the opening of the loading cover.
  • IT MI20 111 930 A1 discloses a device for controlling the delivery of waste in a bin, wherein said bin comprises a tank and at least a hatch engaged above the tank and a locking devices operatively engageable between the hatch and the tank and selectively activated to enable and selectively inhibit the lifting of the hatch from a closed condition.
  • a mechanism for unlocking and locking an urban waste container swing lid according to independent claims 1 and 2 is provided. Also disclosed herein is an urban waste container comprising said mechanism for unlocking and locking the lid.
  • the present mechanism for unlocking and locking an urban waste container swing lid comprises a moving member that is hinged to a container lid. Said moving member may be attached to the container lid through a hinge that may be made integral with or attached to the swing lid.
  • a restraining mechanism is also provided intended to lock the moving member for preventing the container lid to be swung.
  • the restraining mechanism comprises a rotating control arm that is arranged to be rotated around a pivot axis into at least an unlocking position where the moving member is allowed to move so that the lid is unlocked, and a locking position where the moving member is prevented from being moved so that the lid is locked.
  • the rotating control arm can only be driven in rotation, that is, the control arm is restricted to performing a rotational movement in both rotation directions. Rotation of the rotating control arm may be performed by any suitable driving means such as an electric linear actuator or an electric motor.
  • a suitable switchboard may be provided to control said driving means.
  • the driving means comprise an electric linear actuator
  • this is preferably arranged to act perpendicular to the rotating control arm.
  • other angles of attack to the rotating control arm than 90° are possible depending on the architecture of the assembly or other issues as required.
  • no or almost no radial force is generated such that all or nearly all the acting force is tangential force as a result of which the force required for actuating the rotating control arm to bring the swing lid into the unlocking position is advantageously reduced.
  • the electric linear actuator is arranged to directly act on the rotating control arm.
  • the rotating control arm is driven in rotation not directly but through a suitable element such as a drive cam.
  • a drive cam is provided whose rotation results in the rotating control arm to be rotated into at least the unlocking position or into the locking position. That is, rotation of the driving cam may cause the rotating control arm to be rotated into at least said unlocking position where the moving member is allowed to move and thus unlocking of the lid or into said locking position where the moving member is prevented from being moved and thus locking of the lid.
  • the driving means may comprise an electric motor suitable for driving the drive cam in rotation for unlocking and locking a waste container swing lid.
  • the rotating control arm may have an arm locking area, for example, at one free end thereof.
  • the arm locking area is intended to come into frictional contact with a corresponding locking area formed in the moving member so as to lock it in the locking position. This ensures suitable locking of the swing lid to the container always even in containers where the lid, once closed, does not always remain in the same position relative to the container body, for example, due to a deformation of the lid in its swing movement.
  • the moving member may be a cylinder and the restraining mechanism may comprise said cylinder and a piston arranged inside the cylinder such that the cylinder is divided internally into two chambers.
  • This cylinder and piston mechanism may be a hydraulic and/or pneumatic mechanism that may include therein inert gas or nitrogen and oil.
  • the piston is movable inside the cylinder depending on the state of at least one valve designed to allow or prevent the passage of fluid between both chambers of the cylinder interior depending on the position of the restraining mechanism
  • the cylinder or the piston may be hingedly mounted to the swing lid of the waste container and the other of the cylinder or the piston may be hingedly mounted to the rotating control arm.
  • the rotating control arm is caused to rotate acting on a switch that is adapted to be operated according to the position of the said valve arranged inside the cylinder, allowing or preventing the passage of hydraulic fluid between the chambers inside the cylinder to place the assembly in the unlocked position or in the locked position.
  • Biasing means may be provided acting to arrange the rotating control arm in the locking position.
  • the biasing means may be, for example, a torsion spring.
  • the biasing means may be, for example, a compression or helical spring.
  • many other equally suitable means for bringing the rotating control arm into the locked position may be provided acting to arrange the rotating control arm in the locked position.
  • Control means may be provided for controlling the restraining mechanism.
  • Such control means may include at least one or more of: a switch adapted to be operated according to the position of the moving member, a switch adapted to be operated according to the position of the rotating control arm, and a switch adapted to be operated according to the position of the drive cam.
  • a switch adapted to be operated according to the position of the moving member a switch adapted to be operated according to the position of the rotating control arm
  • a switch adapted to be operated according to the position of the drive cam One or more of said types of switches may be provided depending on the requirements.
  • Suitable activation means may be also provided for operating the driving means.
  • Examples of such activation means may include one or more of a push button, a pedal, a presence sensor, a card reader, a mobile device, or a remote control.
  • Other activation means such as smart mobile devices, for example phones, tablets, etc.
  • Operation of the driving means may be performed by a remote control from a service manager, for example.
  • a locking pin may be provided between the moving member and the rotating control arm.
  • Said locking pin is movable so that it can be positioned in a first position and in a second position.
  • the locking pin first position when the rotating control arm is the unlocking position where the moving member is allowed to swing the lid, the locking pin prevents the moving member from abutting the rotating control arm, for example, by gravity.
  • the locking pin second position In the locking pin second position, the moving member is allowed to abut the rotating control arm thus preventing the rotating control arm from being rotated by the moving member.
  • the locking pin also acts as a guide as the lid is swung avoiding noise that would be generated by the moving member when abutting the rotating control arm.
  • a very simple and compact and yet effective mechanism is obtained for unlocking and locking a swing lid in an urban waste container such that it can be swung or not as required.
  • the swing lid unlocking and locking mechanism described above is thus cost-effective and reliable, and requires very low maintenance.
  • compactness is very advantageous in this case so that the whole mechanism can be easily installed within an isolated compartment located externally at one side of the container body.
  • An urban waste container comprising at least a swing lid and the unlocking and locking mechanism described above for locking and unlocking the swing lid of the container.
  • the unlocking and locking mechanism described above can be suitably controlled by an intelligent control system.
  • Such intelligent control system may be configured to restrict the use of the urban waste container to only those persons who have been previously authorised to do so in order to reliably establish control over who is using the container and to determine whether a user is correctly sorting waste in order to encourage selective waste collection.
  • the intelligent control system may include a reader capable of reading a magnetic card including data associated with a user and/or a community of neighbours, company employees, or any group of people, etc. According to the reading of the information contained in the magnetic card, the intelligent control system outputs a command for actuating the unlocking and locking mechanism described above so that the container lid can only be opened if certain preset conditions are met.
  • Such conditions may include, for example, the identification or recognition of the person(s) using the container.
  • Other conditions are possible.
  • the magnetic card may be replaced with a mobile device such as a smart phone, tablet, smart watch, etc. via a Bluetooth operated mobile application, for example.
  • Other means for storing and transmitting information are possible.
  • the waste container described above provided with the present unlocking and locking mechanism and with the above-mentioned intelligent control system, provides many advantages. In addition to ensuring that the lid is properly locked in a rest position, it makes it more difficult to misuse the container since access is restricted, and encourages the user to sort waste correctly, reducing the proportion of improper waste.
  • the intelligent control system can also collect information on what type of waste is thrown into the container or how often this is performed, as well as recording data on container use, and reporting it at a certain frequency, for example, daily, to a central waste management service. With this, it is possible to have a remote control that allows to determine if neighbours in a community, employees in a company, or any group of people using containers of the type described above are making a correct selective collection. Monitoring the frequency of use of the container enables it to provide information that can be then used to optimize collection routes. This is very advantageous for management and control of preventive maintenance and cleaning services of the containers.

  • intelligent control system may include a magnetic card reader arranged in the aforementioned position A on the outside of the waste container 400, as shown in figure 1 of the drawings. Validating data on a magnetic card when placing it near the reader in the container 400 allows or prevents the activation of the unlocking and locking mechanism 100.
  • the unlocking and locking mechanism 100 is effective in protecting access to the waste container 400. Even if the lid 450 of the waste container 400 does not reach the closed position, the position in which the lid 450 is located is detected by position sensors which detect the position of the moving member 110 or the cylinder 310 indicating that the lid 450 has not reached its closed position and the control system can software-decide that the drive cam 210 should also be operated to lock the lid 450, even if it is not completely closed.
  • Means for monitoring the status of the unlocking and locking mechanism 100 and the position of the lid 450 may be provided in cooperation with the above-mentioned switches S1, S2, S3 to determine whether the lid 450 is closed or not. If the lid 450 is not completely closed, even though it is locked in the container 400, an alarm may be output to a control or maintenance centre.
  • the unlocking and locking mechanism 100 is located in the area A, outside the loading area of the container 400 and the waste therein, waste is prevented from being deposited in the area of the unlocking and locking mechanism 100 which could compromise unlocking and, above all, locking of the lid 450. As it is not visible, the unlocking and locking mechanism 100 is protected from vandalism, external agents and impacts from pressurised water and chemicals during washing process of the container 400.
  • the base plate 610 may however be rigidly or releasably connected to the base plate 610.
  • other parts such as any of the switches S1, S2, S3 may be also connected to the base plate 610 in any suitable way.
