[0001] The present invention relates to a closure device for waste collection bins. The
present invention also relates to a waste collection bin equipped with said device.
[0002] Examples of collection bins equipped with a closure device are known from
US 2013/334229 A1,
US 2006/016816 A1 and
US 6 053 354 A, wherein
US 2013/0334229 A1 discloses a closure device according to the preamble of claim 1. In particular
US 6 053 354 A provides a waste collection bin equipped with a closure device comprising a covering
element having a proximal portion rotatably coupled to the support structure and a
distal portion movable about a pivoting axis (X) of the proximal portion, and an access
door rotatably coupled to the distal portion of the covering element about a joint
axis (Y) parallel to the pivoting axis (X).
[0003] In particular, the present invention is suitable for use on waste collection bins
of the type that stand on the ground - usually on a pavement and/or at the side of
a road - to allow the collection of waste from local inhabitants, and which are emptied
at regular intervals by being lifted and tilted by means of a gripper device installed
on an appropriately equipped motor vehicle.
[0004] Examples of such tiltable collection bins are known from
DE 197 47 020 A1 and
NL 1 009 273 C1. In particular
NL 1 009 273 C1 provides a waste collection bin equipped with a closure device comprising a support
structure rigidly carried on top of a containment tank and a covering assembly operatively
borne by the support structure to close the containment tank at the top. The covering
assembly comprises at least one covering element having a proximal portion rotatably
coupled to the support structure and a distal portion movable about a pivoting axis
of the proximal portion. Various waste collection bins of the type described above
are known in the prior art and essentially comprise a collection tank, made of metallic
or synthetic material, with a closure device at the top.
[0005] The closure device must guarantee adequate protection of the contents against atmospheric
factors, theft and/or vandalism and prevent the entry of animals, while ensuring ease
of access for users wishing to use the waste collection bin.
[0006] Current trends focusing on sorting waste collection also impose an adequate monitoring
of the type of objects that can be placed in each bin, to prevent the introduction
of materials that do not comply with certain specifications, typical of the sort of
waste for which that particular waste collection bin is used. In that respect, one
measure that is typically used consists in providing the closure device with one or
more access doors, each associated with a filling mouth of an appropriate shape and
size suitable for exclusively enabling insertion of objects of a shape and size consistent
with those typical of the type of waste to be collected. The opening of the access
door may be subject to recognition of an ID code assigned to each user, so that it
is also possible to monitor the amount and type of waste collected by each person
or group of people.
[0007] To guarantee a convenient and effective emptying of the collection bin in the tilting
phase, it is also needed that the closure device also is provided with a large emptying
door that is normally held in the closed position when the waste collection bin is
standing on the ground for normal use and can be opened when the waste collection
bin is tipped, for enabling the waste to fall into the hopper of the waste collection
vehicle.
[0008] The emptying and access doors may be accessible from respectively opposite sides
of the waste collection bin, typically identified as the "road side" and the "pavement
side". In other words, the closing element in the waste collection bins of the type
described above may have, on the pavement side, one or more access doors having relatively
small dimensions, and a large door on the road side, usually locked for users and
which can only be opened in consequence of the tilting of the waste collection bin
during emptying.
[0009] However, the consequent limitation associated with the possibility of only permitting
the collection of waste through one side of the waste collection bin prevents its
proper use in particularly narrow roads and/or in circumstances in which it has to
be placed close to walls, fences or other architectural barriers, as is typically
the case for example in lanes or relatively narrow roads. In this case, the user has
no option but to insert the waste through the larger opening, which must necessarily
be arranged on the road side to allow the waste collection bin to be emptied. However,
installation in such circumstances would mean waste would have to be collected through
the large door, with the subsequent loss of control over the type of waste that is
collected.
[0010] Waste collection bins in which the access doors are incorporated in the larger emptying
door have also been developed, so that waste can also be collected from the road side
while keeping the emptying door closed. However, the subsequent structural weakening
of the emptying door, the increased weight on the latter due to the installation of
the access doors and of the electronic and/or electromechanical apparatuses connected
to them, and the significant forces applied to the assembly during the tilting of
the waste collection bin make it difficult to achieve a satisfactory degree of efficiency
and functional reliability.
[0011] A further limit that has been found in the solutions in which the access doors are
incorporated in the emptying doors is the fact that they cannot be fitted with a pedal
to facilitate waste collection under hygienic and ergonomic conditions.
[0012] According to the present invention, the Applicant believes that the prior art can
be improved, with a closure device suitable to incorporate in a single closing element
the function of providing controlled access as regards the placing of waste in the
waste collection bin, and that of opening to enable the effective emptying of the
waste collection bin by tilting. In particular, the Applicant has found that it is
possible to optimise the containment and distribution of the masses and adequately
protect any electronic and electromechanical devices from excessive stresses, by using
a covering assembly that has a covering portion oscillatably constrained to a support
structure that can be rigidly anchored to the tank of the waste collection bin, and
a closure portion that can be moved separately to permit the collection of waste in
the waste collection bin, and jointly with the covering portion to open a wide passage
through which the waste can pass during emptying.
[0013] More in particular, the invention relates to a closure device for waste collection
bins, as claimed in claim 1.
[0014] According to a further aspect, the invention also relates to a waste collection bin
incorporating said closure device, as claimed in claim 13.
[0015] The transverse dimensions of the covering element influence the size of the opening
that is created to allow waste to be placed in the waste collection bin, when the
access door is raised by the user to an open condition.
[0016] The covering element is, in turn, able to rotate about the pivoting point during
the tilting of the waste collection bin, pulling with it the access door attached
to it, to guarantee a wide opening through which the waste can flow out during emptying,
regardless of the size of the access door.
[0017] By appropriately sizing the covering elements and access doors it is therefore possible
to adapt the closure device to suit any type of waste for which the waste collection
bin, on which the closure device must be fitted, is intended.
[0018] The access door remains available to the user for waste collection, regardless of
the fact that the covering element is being held in the rest condition.
[0019] The use of the support structure allows easily installing the closure device, even
on tanks of existing waste collection bins, eventually in substitution of the closure
devices with which they were previously equipped.
[0020] Further preferred characteristics of the invention are disclosed in the dependent
claims. More in particular, in at least one of the aforesaid aspects, the invention
further comprises one or more of the following preferential characteristics.
[0021] The distal portion and the proximal portion are rigidly integral with the covering
element.
[0022] Preferably, the support structure comprises at least a pair of side panels mutually
spaced apart and each of which can be fixed to the continuation of a side wall of
the containment tank.
[0023] On occurrence, the support structure may also be provided with respective front and/or
rear panels, extending between the side panels on the vertical continuation of the
front and back walls, respectively, of the containment tank.
[0024] Preferably, each of said covering elements and access doors, or at least one of them,
is made in the form of a monolithic shingle.
[0025] Preferably, each of said covering elements and access doors, or at least one of them,
has its own pivoting axis or, respectively, joint axis extending perpendicularly with
respect to the side panels of the support structure, and/or parallel to a tilting
axis of the waste collection bin. Preferably, longitudinal ends of the covering element
overlap and rest on the support structure.
[0026] Preferably, the longitudinal ends of the covering element are aligned with respect
to one another along a direction parallel to the pivoting axis. Preferably, the end
edge of the access door rests on the support structure and/or on an upper edge of
the front wall of the containment tank. Preferably, the covering assembly further
comprises at least one auxiliary access door rotatably constrained to the support
structure.
[0027] It is therefore possible for waste to be collected easily from two respectively opposite
sides of the waste collection bin, for example from the road side and from the pavement
side, without undermining the efficacy of emptying said bin, which can always be performed
from the road side towards which said covering element is operated, and without undermining
the use of the waste collection bin by users when it has to be placed against a wall
of a building, fence or other architectural barrier which obstructs access from the
pavement side.
[0028] Preferably, the auxiliary access door is constrained close to or in correspondence
with the pivoting axis of the proximal portion.
[0029] Preferably, the dimensions of the access door and of said auxiliary access door are
substantially identical.
[0030] In an example of a preferred embodiment, there are at least two of said covering
elements and two access doors, each rotatably constrained to the distal portion of
one of said covering elements.
[0031] Preferably, the pivoting axes of the proximal portions of said covering elements
are coincident with one another.
[0032] Preferably, the pivoting axes of the proximal portions of said covering elements
are spaced apart with respect to one another.
[0033] Preferably, in the rest condition the distal portion of the covering element rests
close to or against, the support structure.
[0034] The selective engagement devices are also configured to release the covering element
to allow it to move to the open condition, in consequence of tilting of the closure
device - or of the entire waste collection bin when the closure device is mounted
on the containment tank - about a horizontal tilting axis.
[0035] The selective engagement devices are configured to determine the switching from the
locked condition to the released condition in consequence of the tilting of the closure
device - or of the entire waste collection bin when the closure device is mounted
on the containment tank - between the waste collection condition and the waste emptying
condition.
[0036] Preferably, the selective engagement devices operate between the covering element
and a locking lug integrally attached to the support structure.
[0037] Preferably, said selective engagement devices comprise a pendulum carried by the
covering element so as to be able to oscillate about a horizontal axis and which can
be positioned vertically below a locking lug integrally attached to the support structure.
[0038] Alternatively, the selective engagement device of the covering device may consist
of a pair of mechanical gravimetric devices (pendulums) located close to the ends
of the horizontal pivoting axis of the access door.
[0039] According to further possible alternative embodiments, the pendulum or pendulums
may be constrained to the support structure, with the locking lug(s) integral with
the covering element.
[0040] Preferably, the horizontal axis of oscillation of the pendulum is parallel to the
pivoting axis of the covering element and/or to said horizontal tilting axis.
[0041] There are also preferably provided locking devices acting on said access door and
at least one electronic control unit, acting on the locking devices to selectively
enable the opening of the access door.
[0042] Preferably, the electronic control unit is fixed to the support structure.
[0043] The absence of the additional kinematic mechanisms used in the prior art solutions
to obtain a shifting of the cover in order to widen the opening during the emptying
process, advantageously makes it possible to have two separate control pedals, each
associated with one of the access doors, one on the road side and the other on the
pavement side. Preferably, each pedal is hinged to the base of the vertical walls
of the containment tank, for example close to the vertical centre line thereof.
[0044] Further characteristics and advantages will become clear from the following description
of some preferred, but not exclusive, embodiments of a closure device for waste collection
bins and of a waste collection bin incorporating said device, according to the present

embodiments of the device according to the invention.
[0045] With reference to the accompanying Figures, denoted as a whole by reference numeral
1 is a closure device for waste collection bins, according to the present invention.
The device 1 is suitable to be coupled to a containment tank 2 to implement, as a
whole, a waste collection bin 3 denoted as a whole by reference numeral 3.
[0046] For that purpose, the device 1 essentially comprises a support structure 4 that can
be rigidly engaged on the top perimeter edge of the containment tank 2, for example
by means of threaded members, rivets or welding. In the example that is illustrated,
the containment tank 2 has a truncated pyramid shape with a rectangular base, in which
a front wall 5 and a rear wall 6 face one another and are joined to one another by
two side walls 7 arranged opposite one another. Each side wall 7 bears, in correspondence
with a vertical centre line, respective grip pivots 8 arranged coaxially with respect
to one another and which can be operatively engaged by a tilting device (not illustrated)
installed on-board a waste collection vehicle.
[0047] The support structure comprises a pair of side panels 9 spaced apart from one another
and each of which can be fixed to the continuation of one of the side walls 7 of the
containment tank 2. If necessary, the support structure 4 may also be provided with
respective front panels (not present in the examples that are illustrated) and rear
panels 9a (Figure 9), extending between the side panels 9 on the vertical continuation
of the front 5 and rear walls 6 of the containment tank.
[0048] A covering assembly 10 designed to close the containment tank 2 of the waste collection
bin 3 at the top is operatively coupled to the support structure 4. The covering assembly
10 comprises at least one covering element 11 having a proximal portion 11a rotatably
constrained to the support structure 4 in correspondence with a first pivoting axis
X preferably perpendicular to the side panels 9 of the support structure 4, and parallel
to a tilting or common alignment axis X
1 defined by the grip pivots 8. Said pivoting axis X may be defined for example by
at least a first hinge 12 that is fixed with respect to the support structure 4. The
covering element 11 also has a distal portion 11b movable about the first pivoting
axis X due to the oscillation of the entire covering element 11, between a rest condition
in which the distal portion thereof 11b rests on the support structure 4 (e.g., Figures
3 and 5), and an open condition in which the distal portion 11b is spaced from the
support structure 4 (Figure 6).
[0049] The covering assembly 10 further comprises at least one access door 13 rotatably
constrained to the distal portion 11b of the covering element 11, preferably about
a first joint axis Y parallel to the first pivoting axis X. The joint axis Y may be
defined, for instance, by at least a second hinge 14 that is movable with respect
to the support structure 4. The access door 13 is angularly movable about its joint
axis Y, between a rest condition in which it lies with its end edge resting on the
support structure 4 and an open condition (Figures 2 and 4) in which its end edge
is raised with respect to the support structure 4 to create an opening through which
the containment tank 2 can be accessed.
[0050] In the examples that are illustrated, each of said covering elements 11 and access
doors 13 is made in the shape of a monolithic shingle, extending perpendicularly with
respect to the side panels 9 of the support structure 4, parallel to the first pivoting
axis X. In the rest condition, the longitudinal ends of the covering element 11 overlap
and rest on the top edges of the side panels 9 of the support structure 4, whereas
the end edge of the access door 13 rests on the front panel of the support structure
4 and/or on the top edge of the front wall 5 of the containment tank 2. Alternatively,
in the rest condition the covering element 11 may be supported only by the access
door 13 owing to the connection determined by the movable hinge 15, in the distal
portion 11b.
[0051] As illustrated by way of example in Figures 1 to 8, the covering assembly 10 may
further comprise at least one auxiliary access door 15, rotatably constrained to the
support structure 4, for example by means of a respective auxiliary hinge 12a close
to the first pivoting axis X of the proximal portion 11a or so as to coincide therewith.
The auxiliary access door 15, which in a preferred embodiment is substantially identical
in size to the access door 13, permits the collection of waste from the side of the
waste collection bin 3, usually from the so-called "pavement side" opposite the side
towards which the covering element 11 operates with the respective access door 13.
[0052] There may also be provided appropriate locking devices 16, acting on each of the
access doors 13, 15, to hold them in the closed condition to prevent unauthorised
access through the closure device 1. Said locking devices 16, which are not described
in detail in that they can be implemented in a known way, may for example comprise
electromechanical latches fixed to the inside of the support structure 4 or which
can be engaged in the containment tank 2.
[0053] At least one electronic control unit 17, which is also not described in detail in
that it can be implemented in a known way, operates the locking devices 16 to selectively
enable the opening of one or both of the access doors 13, 15, preferably in consequence
of the recognition of an ID code previously assigned to the user, for example read
from a badge or keyed in from a keypad. Advantageously, the electronic control unit
17 may be fixed to the support structure 4, for example to one of the side panels
9 or to one of the walls 5, 6, 7 of the containment tank 2, as indicated in the example
shown.
[0054] The covering element 11 may, if necessary, bear a reading unit 18, which could interface
with the electronic control unit 17 to monitor the level of filling inside the containment
tank 2, for example by means of ultrasound sensors or other reading devices.
[0055] During normal use, the waste collection bin 3 stands on the ground in a waste collection
condition, normally at the side of a road. The front wall 5 of the containment tank
2 and the covering element 11 face the so-called "road side" of the waste collection
bin 3, that is to say, they face the road. The rear wall 6 of the containment tank
2 and the auxiliary access door 15 face the so-called "pavement side", opposite to
the road side.
[0056] In order to introduce waste in the waste collection bin 3, the user identifies him
or herself using the electronic control unit, which subsequently controls the locking
devices 16 to enable the opening of at least one of the access doors 13, 15. It may
be possible to enable the opening of both of the access doors 13, 15, or of just one
of them, for example selectable by the user and/or based on the data obtained by the
reading unit 18 as a function of the level of waste in different areas of the containment
tank 2 so as to ensure the equal distribution of waste inside said tank.
[0057] The user may therefore open the access door 13 manually or using a control pedal
19 located at the base of the containment tank 2. Advantageously, there may be two
separate control pedals 19, each connected to one of the access doors 13, 15 respectively
facing the road side and the pavement side, hinged to the base of the vertical walls
of the containment tank 2 close to the vertical centre line, and connected to said
doors by means of levers and/or tie-rods which are not illustrated since they are
known in the prior art.
[0058] When the access door 13 is opened, waste can be introduced into the containment tank
2 through the opening that is created between the covering device 1 and the containment
tank 2. The size of the opening may be relatively small, dictated by the size of the
access door which, in the design and construction stage, can be chosen according to
the dimensional characteristics of the type of waste for which the waste collection
bin 3 is to be used. For example, if the waste collection bin 3 is used to collect
paper and card board, the opening could be in the form of a slot just a few centimetres
high.
[0059] To be emptied, the waste collection bin 3 is designed to be lifted from the ground
and overturned by rotating about the grip pivots 8 over a hopper with which the waste
collection vehicle is fitted. The consequent tilting of the closure device 1 about
the horizontal tilting or common alignment axis X
1 of the grip pivots 8 causes the opening of the covering element 11, due to the force
of gravity, which moves from the rest condition to the open condition, also bringing
with it the access door 13 constrained at the second hinges 14. In the waste emptying
condition illustrated in Figure 6, a large opening is therefore created in the closure
device, through which the waste can flow freely out of the containment tank 2 and
fall into the hopper due to the force of gravity.
[0060] Between the access door 13 and the covering element there may be limiting means 31a
to limit the maximum angular travel of said door about the second hinges 14 in order
to prevent excessive movements and possible collisions inside the hopper of the vehicle.
[0061] To prevent accidental or unintentional opening of the covering element 11 when the
waste collection bin 3 is standing on the ground, selective engagement devices 20
may be provided to selectively hold the covering element 11 in the rest condition,
when the covering device 1 is in the waste collection condition. The selective engagement
devices 20 preferably operate between the covering element 11 and a locking lug 22
integrally attached to the support structure 4.
[0062] The selective engagement devices 20 can be switched between a locked condition in
which they hold the covering element 11 in the rest condition, and a released condition
in which they free the covering element 11 so that it can be moved.
[0063] The switching from the locked condition to the released condition may advantageously
occur in consequence of tilting of the closure device 1 - or of the entire waste collection
bin 3 when the closure device is mounted on the containment tank 2 - between the waste
collection condition and the waste emptying condition.
[0064] Said selective engagement devices 20 may for example comprise at least one pendulum
21 or other mechanical gravimetric device, borne by the covering element 11 so as
to be able to oscillate about a horizontal axis, preferably parallel to the pivoting
axis X and/or to the tilting axis X
1, and which can be positioned vertically below the locking lug 22. The pendulum 21
is therefore suitable to interfere with the locking lug 22 to prevent the covering
element 11 from being raised by the user, in order to prevent the introduction of
objects of a size and shape not consistent with the type of waste for which the waste
collection bin 3 is intended.
[0065] Alternatively, the pendulum 21 may be connected to the support structure 4, with
the locking lug 22 integral with the covering element 11.
[0066] The selective engagement devices 20 can be switched between the locked condition
and the released condition without interfering with the access door 13. The user can
therefore introduce waste through the access door 13, even when the covering element
11 is held in the rest condition.
[0067] During the tilting of the waste collection bin 3 towards the emptying condition,
the pendulum element 21 oscillates owing to the force of gravity about its own axis
of constraint, so as to release the locking lug 22 and so allow the movement of the
covering element 11 towards the opening condition.
[0068] Figures 8 to 11 illustrate further preferred embodiments of the invention. For the
sake of conciseness, only certain distinguishing aspects of these will now be described,
with respect to the embodiments described above in detail and illustrated in Figures
1 to 7, since their other aspects are conceptually identical.
[0069] The example in Figure 8 is conceptually identical to that of the structural examples
illustrated in Figures 1 to 7 but, unlike these, the auxiliary access door 15 is constrained
to the support structure 4 in correspondence with the same pivoting axis X defined
by the first hinge 12 which constrains the covering element 11.
[0070] In the example in Figure 9 only the access door 13 is constrained to the covering
element 11 by means of the respective second hinge 14. The covering element 11 is,
in turn, constrained to the support structure 4 by means of the first hinge 12 placed,
for example, at the top of the rear panel 9a on the vertical continuation of the rear
wall 6 of the containment tank 2.
[0071] In the example in Figure 10 there are two covering elements 11 constrained to the
support structure 4 along a common pivoting axis X by means of a single first hinge
12, and each of which bears a second hinge 14 to engage a respective access door 13.
[0072] Figure 11 shows an embodiment with two covering elements as envisaged in Figure 6,
but constrained to the support structure in correspondence with respective first hinges
12 arranged side by side so that the respective pivoting axes are at a short distance
from one another.
