Description

Technical field of the invention

The present invention relates to a device for controlled waste depositing which controls the disposal of a waste. It is also an object of the invention a waste container integrating the aforesaid device.

Background of the Invention

A waste collection in urban areas is usually done with the help of special containers, conveniently placed in the city area to enable citizens to dispose of a waste. Waste containers are periodically emptied by companies authorized to collect and transport the waste with specially equipped vehicles, which transport waste to places designated for processing. For the purpose of the waste collection in the city environment, where separate collection is required, they are ready, each for itself, intended for a separation or disposal of each specific type of waste according to the users.
In order to enable a control and supervision of the user how he disposes of waste, the proposed solution of the invention also enables a recording of a waste disposal after identification of the user.
The present invention includes a locking mechanism preventing direct unauthorized waste disposal, making it possible only after unlocking an access to a waste deposit drum with the use of a user key coded to the name of the user of a device of the present invention. With the same key, the user can unlock any device for controlled waste depositing in an area of operation of the waste collection and transport company with which the user has entered into a contract. By inserting the code user key into a lock, the device is automatically activated following the user identification sequence. The device for controlled waste depositing does not use electricity for its operation, but bases its work on pure mechanical work.
One of the disadvantages related to devices for this purpose that are currently in use is their relative vulnerability to external disturbances.
In particular, it is possible to confirm that the systems currently in use disrupt themselves by encouraging malicious users who are ready to initiate the procedure by inserting cards or other flexible thin elements into the gap between the movable parts near the disposal opening, until they achieve the unlocking of the locking mechanism so that they can dispose of waste without identification, for example anonymous disposal of materials other than those prescribed by separate collection, or to bypass the tariff collection based on the number of disposed waste making and/or a smaller amount of disposal of the user.
The next problem that appears in the existing devices is the malfunctions that occur when the user tries to open a mechanism of a disposal opening, controlled by a lever and/or a foot lever, when he has not yet completed the identification. In this case, it can easily happen that the mechanical parts under the action of the user's force on the lever or foot lever are not able to move the necessary unlocking mechanism of the disposal opening when the electronic interface, with the recognition of the user's code, enables the disposal operation.
In many cases, the user explains the failure of the unlock as a malfunction of the system, and places his nameless waste next to the container. Another problem that is increasingly appearing in the field is the demand for devices that can work successfully without the need to connect to an electrical supply network. Such requirements are typically met with the use of independent battery power, which can be supplemented by the use of photovoltaic cells. However, the use of these independent battery supplies requires an important need to reduce the energy consumption of the IT and automated tank equipment as much as possible, and especially the electromechanical locking system used to lock and unlock the hatch. The use of battery devices requires regular maintenance, but low temperatures often cause malfunctions. This invention uses exclusively mechanical work for its operation, which is performed in the form of turning a key, which moves a lever mechanism that allows the user to open a waste deposit drum for depositing a waste. After closing the waste deposit drum, the mechanism locks automatically.

Summary of the Invention

The object of the present invention is to provide an improved device that is effectively protected against any interference at the moment of an attempt to unlock the storage hatch by an act of fraud, which is achieved by the high security of the protection of a lock and key used.
A further object of the present invention is to provide a device that works efficiently in real conditions, even when an inexperienced user acts clumsily on a lever trying to open a waste hatch even though the identification has not yet been completed.
The goal of the present invention is to provide a cheap and simple device made from as few parts as possible, the production of which is not demanding and complicated, while at the same time ensuring durability and reliability in application.
In the first aspect, the present invention relates to a device for waste disposal in the city, which consists of a fixed part united with a waste container on which there is a disposal opening, a movable part connected to a stationary one, and a control of the movable parts between a closed position when the disposal of waste is prevented and an open position where the waste disposal is possible. Preferably, between the stationary and the moving part, a locking mechanism consisting of a pivoting lever, a lock with a key, a gravity brake, two sliding stops and several mechanical stops that all interact with each other. It is necessary to harmonize operation of the locking mechanism of a waste deposit drum a mechanism operating a curved pivoting bottom door configured for opening or closing the waste deposit drum. The purpose of slide stops, mechanical stops and a pivoting motion of the pivoting lever that carries the slide stops is to prevent the disposal opening of the waste deposit drum for depositing waste, except when the device for controlled waste depositing is unlocked with a user key.
A device of the present invention is adapted for installation on containers of different sizes and manufacturers. Installation on containers with a volume of less than 1000 liters is possible but it is not profitable since such tanks have to be emptied often, which is not worthwhile for collection service providers.
A locking part by means of a sliding stop mounted on a pivoting lever rotates the pivot lever and sets a second sliding detent in position to engage a mechanical stop and thus cause a waste deposit drum to reopen without unlocking a lock.
In a further aspect, the present invention relates to a waste collection container comprising a device for controlled waste depositing.
According to the embodiment of the invention, a device for controlled waste depositing can be adapted to a size of a waste deposit drum according to the requirements of a waste collection and transport service provider.
Depending on a type of a waste that is inserted into a device for controlled waste depositing, materials used to make the device for controlled waste depositing, or some of its parts, are adjusted accordingly.
According to the embodiment of the present invention, a simultaneous activity of sliding stops and mechanical stops fixedly connected to a waste depositing drum allows for high security in relation to tampering attempts, and offers a possibility of starting a device for controlled waste depositing without the use of great force.

Further, the device housing 17 comprises the lock 5 fixed to a body of the device housing 17, wherein an authorized user operates by rotating the waste deposit drum 3, thereby enabling inserting of the waste in the waste deposit drum 3 by means of a coded user key for unlocking the device for controlled waste disposal 1, wherein a locking action is performed completely automatically by closing the waste deposit drum 3 by the user's action on the handle 4 arranged on an outer side of the waste deposit drum 3.
With reference to figures 3 to 8, the first circular side surface 3a of the waste deposit drum 3 is provided with a mechanism operating the curved pivoting bottom door 23 for opening or closing part of the drum where the drum shell is removed and through which waste is fed and through which waste is discharged into the waste container 2 as a result of the rotation of the waste deposit drum 3 by means of the handle 4.
The waste deposit drum 3 is further provided with a locking mechanism. In figures 4, 6, 8 and 9, a missing part of ta drum shell (lateral surface area of the cylindrical surface), namely disposal opening 26 constituting more or equal to 40% of the total lateral surface area of the cylindrical surface is indicated with a dotted line.
An opposite second circular side surface 3b of the waste deposit drum 3 is provided with the locking mechanism enabling disposing the waste into the waste deposit drum 3 by using the coded user key for unlocking the device for controlled waste disposal 1 and after closing the waste deposit drum 3 automatically locking said mechanism preventing unauthorized waste disposal into the waste deposit drum 3, wherein the locking mechanism is configured to enable rotation of the waste deposit drum 3 from an open to a closed position and vice versa.
The mechanism operating the curved pivoting bottom door 23 for opening or closing the disposal opening 26 comprises a curved sliding track 19 configured to enable sliding of a lever 25 along an outer side of the curved sliding track 19. The lever 25 is arranged to slide along the curved sliding track 19, where the curved sliding track 19 is fixedly attached to the first circular side surface 3a of the waste deposit drum 3, and the lever 25 is fixedly connected to a shaft 24 and extends over said first circular side surface 3a. In the accompanying figures, the curved sliding track 19 and the lever 25 are positioned on a left-side surface of the waste deposit drum 3, and the locking mechanism is positioned on a right-side surface of the waste deposit drum. The mechanism providing waste deposit drum 3 rotation (opening/closing access to an inside of the waste deposit drum 3) may be arranged on the right-side surface and the locking mechanism on the left-side surface.
The cylindrical surface of the waste deposit drum 3 comprises the disposal opening 26 in a form of the missing part of the drum shell. The disposal opening 26 of the waste deposit drum 3 may be in an open or closed position by means of the curved pivoting bottom door 23. The curved pivoting bottom door 23 is hardwired (or coupled) to the shaft 24 by a hinge assembly and configured to rotate around the shaft 24. The lever 25 is fixedly connected to the shaft 24, the lever 25 is extending over the first circular side surface 3a provided with the curved sliding track 19. The lever 25 may be arranged in a first position when the disposal opening 26 of the of the waste deposit drum 3 is opened and in a second position when the disposal opening 26 of the of the waste deposit drum 3 is closed by the curved pivoting bottom door 23. The curved pivoting bottom door 23 is fixedly attached to the shaft 24 along the entire length of the curved pivoting bottom door 23, and the shaft 24 is fixed to the mechanism carriers 6 and 22. The curved pivoting bottom door 23 is configured to slide inside an inner surface of the waste deposit drum 3, so when the waste deposit drum 3 rotates clockwise in the direction that allows garbage to be deposited into the waste deposit drum 3, the curved sliding track 19 pushes the lever 25 from the first position into the second position the disposal opening 26 enabling depositing the waste into the waste deposit drum 3, said waste deposit drum 3 starts rotating counterclockwise, the curved sliding track 19 also rotates enabling sliding of the lever 25 from the second position to the first position, rotating the curved pivoting bottom door 23 around the shaft 24 and allows waste to be discharged from the waste deposit drum 3 into waste container 2. In position when the disposal opening 26 of the waste deposit drum 3 is opened, the disposal opening 26 is directed towards a bottom of the waste collection container 2 enabling the waste to fall out of the waste deposit drum 3 into the waste collection container 2.
With reference to figures 6 to 9, the locking mechanism is arranged consisting of the lock 5 for receiving the coded user key, pivoting lever 7, slide stops 9 and 10, gravity brake 8, pivoting lever shaft 15, return spring 16 and first, second, third and fourth (four) mechanical stops 11, 12, 13 and 14. The mechanism carrier 6 is fixedly connected to the device housing 17 and at the same time holds the waste deposit drum 3 and the pivoting lever 7. The pivoting lever 7 is arranged parallel to the mechanism carrier 6 and configured to oscillate around the pivoting lever shaft 15, the pivoting lever shaft 15 is arranged perpendicular to the shaft 18. The waste deposit drum 3 rotates around the drum shaft 18 and turns the pivot lever 7 around the pivoting lever shaft 15.
The lock 5 is fixed to the body of the device housing 17. By inserting the user key into the lock 5 and turning it for 180°, the locking mechanism is released and the user can lift the handle 4, open the waste deposit drum 3 and insert the waste through the disposal opening 26 into the waste deposit drum 3. Lowering the handle 4 closes the waste deposit drum 3 and the inserted waste falls into the waste container 2. For each waste deposit, the user must reinsert the user key and turn it.
On one edge the pivoting lever 7 is configured to be pivotable around shaft 15 between a locked position and unlocked position. The pivoting lever 7 on an upper side oriented to the device housing 17 comprises two parallelly arranged first and second sliding stops 9 and10 connected to the pivoting lever 7 using frames enabling sliding of the first sliding stop 9 and second sliding stop 10 towards and away from the second side surface 3b of the waste deposit drum 3. The first sliding stop 9 is arranged between the lock 5 and the pivoting lever shaft 15 and the second sliding stop 10 is arranged between the pivoting lever shaft 15 and on the opposite end of the lock 5. At the opposite side of the lock 5, a lower side of the pivoting lever 7 comprises the return spring 16 connecting the mechanism carrier 6 and the pivoting lever 7. The return spring 16 is fixed internally to the lower side of the pivoting lever 7 and the second side surface 3b of the mechanism carrier 6, the return spring 16 is configured to push the pivot lever 7 to an initial locked position. The return spring 16 is configured to bring the pivot lever 7 into the initial locked position when the waste deposit drum 3 is in the closed position, before the action of the unlocking the lock 5. The return spring 16 operates between the pivoting lever 7 and the mechanism carrier 6 fixed internally to the lower side of the pivoting lever 7 and the second side surface 3b of the mechanism carrier 6, the return spring 16 is configured to push the pivot lever 7 to the initial locked position.
By the action of unlocking the lock 5, lifting of the handle 4 to open the waste deposit drum 3 is enabled. As the user lifts the handle 4, the waste deposit drum 3 rotates around the drum shafts18. When unlocking the lock 5 a lock latch is rotated by 45° the gravity brake 8 is released, the pivot lever 7 turns around the pivoting lever shaft 15 and activates the gravity brake 8 which prevents returning the pivot lever 7 into the initial locked position. The gravity brake 8 is rotatably connected to the pivot lever 7 and configured to prevent returning the pivot lever 7 into an initial locked position when the waste deposit drum 3 is in the closed position, before the action of the unlocking the lock 5. This enables the unhindered passage of the second and third mechanical stops 12 and 13 under the second sliding stop 10, and the first mechanical stop 11 skips the first sliding stop 9 preventing the waste deposit drum 3 from returning to its initial locked position, thus ensuring that the user has to complete the entire cycle.
When the third mechanical stop 13 is pushed and the second sliding stop 10 passes, the waste deposit drum 3 has reached an end position (it is closed) and can no longer be opened, which is ensured by the third mechanical stop 13 and the second sliding stop 10. At the same time, the curved sliding track 19 no longer acts on the lever 25, the curved pivoting bottom door 23 rotates around the shaft 24 enabling the waste to fall out of the waste deposit drum 3 into the waste collection container 2.
The second and third mechanical stops 12 and 13 are fixedly attached to the second side surface 3b of the waste deposit drum 3 and arranged so that when the waste deposit drum 3 rotates clockwise they pass under the second sliding stop 10. Likewise, the fourth mechanical stop 14 is also attached to the second side surface 3b of the waste deposit drum 3 and arranged so that when the waste deposit drum 3 rotates clockwise the fourth mechanical stop 14 deactivates the gravity brake 8.
Preferably, when the waste deposit drum 3 rotates to the end position, the fourth mechanical stop 14 deactivates the gravity brake 8, and by the action of the return spring 16, the pivot lever 7 rotates in the counter-clockwise direction and activates the second sliding stop 10.
When rotating the waste deposit drum 3 to the end position, the lever 25 is brought into a position where the curved sliding track 19 no longer acts on the lever 25, the curved pivoting bottom door 23 is automatically released enabling falling of the waste into the waste collection container 2.
Preferably, at a moment when the user inserts the waste into the waste deposit drum 3, by lowering the handle 4, begins to rotate the waste deposit drum 3 in the counter-clockwise direction in order to close it and drop the waste into the waste collection container 2. Upon lowering the handle 4 and rotating the waste deposit drum 3 into the closed position, the fourth mechanical stop 14 is configured to deactivate the gravity brake 8 and the return spring 16 returns the pivoting lever 7 to the initial closed position, wherein simultaneously blocking the second and third mechanical stops 12 and 13 by the second sliding stop 10 preventing returning the waste deposit drum 3 to the open position.
The rotation of the waste deposit drum 3 moves the second and third mechanical stops 12 and 13 under the second sliding stop 10, causing the waste deposit drum 3 to be in the closed position without any possibility to re-open it without re-inserting the user key 5.
The pivoting lever 7, by the action of unlocking the lock 5, turns and activates the gravity brake 8, which prevents the return of the pivoting lever 7 to the initial position, which enables the unhindered passage of the second and third mechanical stops 12 and 13 under the second sliding stop 10, and the first mechanical stop 11 skips the first sliding stop 9 preventing the waste deposit drum 3 from returning to its initial position, thus ensuring that the user has to complete the entire cycle. During the rotation of the waste deposit drum 3 to the end open position, on the opposite base of the waste deposit drum 3, the curved sliding track 19 acts on the lever of the 25 to raise the disposal opening 26 and prepare the space for depositing waste. By rotating the waste deposit drum to the end position, the fourth mechanical stop 14 deactivates the gravity brake 8 and the return spring 16 returns the pivoting lever 7 to the initial position, simultaneously producing the effect that the second and third mechanical stops 12,13 are blocked by the second sliding stop 10, and it is no longer possible to return the waste deposit drum 3 to the open state, but it is necessary to start a new cycle with the help of the user's key.
Elements for unlocking and locking the device 1 are exclusively affected by mechanical forces that the user transmits via the handle 4 to all the mechanism assemblies except for those whose movement is caused by their own weight (gravity force).
When the user's key unlocks the lock 5, the pivot lever 7 is turned and the user's key is returned to the initial position and removed from the lock 5 and no longer affecting the continuation of the cycle. The user's key is in the function of unlocking the device for controlled waste disposal 1, the locking/unlocking action is performed completely automatically by closing the waste deposit drum 3 by the user's action on the handle 4.
Preferably, when the waste deposit drum 3 is closed the locking mechanism no longer allows re-opening. The next generation cycle is only possible after re-inserting the user key and activating the system, which results in a new recording of the waste disposal in the user's new cost record.
