[0001] The invention relates to a disposal lock, which can be made to interact with a receiving
container for inserting products, such as waste, which disposal lock comprises a housing
with a passage, at the upper end of which there is a lid and at a distance below which
upper end closure means are provided, which lid is displaceable between an open position
for inserting waste and a closed position, and which closure means are displaceable
between a closed position for determining a holding volume between the upper end and
the closure means which are in the closed position, and an open position for discharging
waste from the passage, as well as means for varying the holding volume.
[0002] Such a disposal lock is known from European patent application
915,035. The closure means of this known disposal lock consist of two mutually opposite flaps
which are in a horizontal position in the closed state and are directed vertically
in the open state. These flaps can also be moved up and down by means of a special
control device. As a result thereof, the total available volume for holding waste
in the disposal lock can be varied. If the flaps are moved to a high position, only
a relatively small amount of waste can be accommodated in the disposal lock each time.
By contrast, a relatively large amount of waste can be accommodated in the disposal
lock if the flaps are situated in a lower position.
[0003] These different positions can be selected by the user; depending on the selected
volume, the costs for disposing of the waste can be charged to the user. Although
this known disposal lock thus offers the possibility of charging differentiated costs,
depending on the amount of disposed waste, this known device has several drawbacks.
For the purpose of varying the volume, a separate adjustment device is required which,
inter alia, comprises electric motors with associated switches and the like. In addition,
the adjustment device has to be sufficiently strong and solid to be able to resist
the forces which occur when waste is being inserted. Furthermore, it is a drawback
that controlling the adjustment device requires a relatively large amount of energy,
as a result of which the disposal lock is less suitable to be used with a battery
and disconnected from the electricity network.
[0004] In view of these requirements and the rough conditions which prevail in the area
where the adjustment device is situated, there is a considerable risk of failures.
Thus, the adjustment device may become blocked by trapped waste. In addition, the
costs of such an adjustment device are rather high.
[0005] It is therefore an object of the invention to provide a disposal lock of the type
mentioned in the preamble which offers the possibility of differentiating according
to the amount of waste to be inserted, and which furthermore has a strong and trouble-free
construction and requires little power for its operation. This object is achieved
by the fact that the closure means comprise at least two closing elements which are
situated at different distances below the upper end of the passage for determining
the different holding volumes associated with those different distances.
[0006] Depending on the number of closing elements which are situated above one another,
it is possible to select a corresponding number of different holding volumes for the
waste with the disposal lock according to the invention. However, the closing elements
used for this purpose are at a fixed level, so that no separate adjustment means are
required in order to vary the volume for the waste to be inserted. Although this volume
is not continuously adjustable, it is sufficient, in practice, if the user can choose,
for example, from two different holding volumes. Of course, it is also possible to
provide a correspondingly larger number of holding volumes by placing three or more
closing elements above one another.
[0007] In order to ensure that the disposal lock is protected against molestation and the
like, one of the closing elements can be permanently closed. Thus, free access to
the receiving container from outside is prevented at all times.
[0008] For the purpose of controlling the closing elements, only the proven, known control
mechanisms are required, thus making it possible to largely eliminate the risk of
failures. In addition, the costs of such standard components are relatively low.
[0009] Preferably, regulating means are provided for regulating the closing elements in
such a manner that in the closed position of a closing element which is situated at
a greater distance from the upper end of the passage than another closing element,
said other closing element is opened in order to provide a relatively large holding
volume. When the holding volume with the smallest volume is selected, only the associated
closing element has to be closed and the remaining closing elements can be open or
closed. When disposing of the waste in said receiving element with the smallest volume,
all other closing elements will obviously also have to be opened. To this end, the
regulating means are programmed in such a manner that such a procedure takes place
automatically.
[0010] The closing elements may be configured in different ways; preferably they comprise
at least one flap which is pivotable about a substantially horizontal axis. In particular,
each closing element may also comprise two such flaps. Alternatively, however, it
is also possible to use sliding flaps. The flaps may be flat, but a variant in which
the flaps are dish-shaped is possible. Such a dish may, for example, have a convex
or an elliptic shape or the like. Shapes produced by connecting flat flap parts at
an obtuse angle to one another are likewise possible.
[0011] The operation of closing elements situated one above the other may be effected in
a relatively simple manner. By way of example, the embodiment in which each flap is
connected to a lever, the free end of which is connected, via a rod, to a tumbler
which can be driven by means of an electric motor. In this case, the a tumbler may
have two mutually opposite ends on either side of its rotary shaft, each of which
is connected to a lever of a respective flap via a rod. Such an embodiment has the
advantage that little noise is generated during use, due to the controlled movements
of the closing elements during opening and closing.
[0012] An embodiment is known in which a control element is provided which is displaceable
along the housing. With the invention, it is possible to move a flap at a relatively
large distance from the upper end of the passage into the closed state by placing
said control element in a first position and by placing it in a second position which
is offset with respect to the first position, a flap at a relatively small distance
from the upper end of the passage can be moved into the closed state.
[0013] In addition, the control element as such may be configured in such a manner that
it keeps the flap at a relatively large distance from the upper end of the passage
in the closed state while controlling the flap at a relatively small distance from
the upper end of the passage using said control element.
[0014] For the purpose of achieving the desired operation of the disposal lock, the lid
is preferably coupled to the closing elements in such a manner that the lid can only
be moved into the open position if at least one of the closing elements is closed.
Furthermore, the lid and the closing elements may be controlled by means of an electronic
reading device.
[0015] If more than two closing elements are used one above the other, these may also be
controlled by means of one of the abovementioned control elements, in which case the
holding volume can again be selected by keeping the lower closing elements closed
and keeping the upper closing elements open. If each closing element has a separate
control mechanism which operates independently from the other control mechanisms,
it is possible to only close that closing element which is associated with the selected
holding volume, and to always keep the other closing elements in the open position.
[0016] The invention furthermore relates to a waste-collection device which comprises a
disposal lock as described above and a receiving container, wherein the lower end
of the disposal lock cooperates with the receiving container.
[0017] The disposal lock may be powered by means of a solar panel and a battery; alternatively,
the disposal lock may also be powered by the electricity network.
[0018] The invention will now be explained in more detail with reference to an exemplary
embodiment illustrated in the figures, in which:
Fig. 1 shows a front view in perspective of the disposal lock according to the invention;
Fig. 2 shows a rear view in perspective of the disposal lock according to the invention;
Fig. 3 shows a variant of the housing, in perspective with the parts separated;
Fig. 4 shows a further variant of the control device.
[0019] The disposal lock 1 illustrated in Figs. 1 and 2 consists of a housing 2 which extends
between the upper end 3 and the lower end 4. The upper end also comprises the disposal
opening 5, which is closed off by the lid 6.
[0020] A first closing element 7 is attached to the housing 2 at a relatively high level,
and a second closing element 8 at a relatively low level. It is possible to fit further
closing elements at lower levels. The first closing element 7 consists of the flaps
9, 10 while the second closing element consists of the flaps 11, 12. Each flap 9-12
is attached to a pivot pin 13, in such a manner that these can be moved between the
open, vertical position illustrated in the figures, and a horizontal, closed position.
At one end of each pivot pin 13, there is an arm 14 for moving the flaps 9-12 between
their open and closed position.
[0021] The control plate 15 is provided for the purpose of moving the flaps 9-12. This control
plate 15 has two lugs 16. The control plate 15 can be moved up and down inside the
guide rails 17 which are attached to the housing 2. The control plate 15 can be moved
up and down by means of the motor 18 and a transmission (not shown).
[0022] In the position illustrated in Figs. 1 and 2, the control plate 15 is in the lower
position. Both closing elements 7, 8 are then in the open position. When the control
plate 15 is pushed upwards, the lugs 16 come into contact with the arms 14 of the
flaps 11, 12 of the lower closing element 8. As a result thereof, the lower closing
element 8 closes, in such a manner that a relatively large holding volume in the passage
19 in the housing 2 is defined. When the control plate 15 is moved further upwards,
more of its lugs (which are situated at a higher level on the other side of the control
plate 15 than the side on which the lugs 16 are situated) come into contact with the
arms 14 of the flaps 9, 10 of the upper closing element 7, which consequently also
closes. Thus, a relatively small holding volume in the passage 19 is defined.
[0023] In the variant from Fig. 4, another control mechanism for the flaps 9, 10 and 11,
12, respectively, is illustrated. This control mechanism consists of the electric
motor 20 which, via a reduction 30, crank 29 and connecting rod 21, is connected to
the twin-armed tumbler 22. On both arms of said tumbler 22, an actuating rod 23 is
attached, the other end of which is coupled to the lever 25 of a respective flap 9-12.
By operating the electric motor in a suitable manner, the associated flaps 9, 10 and
11, 12, respectively, can be opened or closed. Masses 24 are also attached to the
flaps which have a balancing effect.
[0024] As is illustrated in the cross section of Fig. 3, the passage through the housing
2 may be configured to widen from the top to the bottom. The pivot pins 13 of the
lower flaps 11, 12 are therefore further apart than the pivot pins 13 of the upper
flaps 9, 10. As a result thereof, the risk of blockages in the passage when waste
passes through has been significantly reduced. Such a downwardly widening passage
is also possible in the case of the embodiment from Figs. 1 and 2.
[0025] In the exploded view of Fig. 3, the flaps 9, 10 of the upper closing element 7 are
shown in the open position, flaps 11, 12 of the lower closing element 8 of the lower
closing element 8 are closed, so that, in said position, the disposal lock 1 is suitable
for accommodating a relatively large amount of waste. The flaps 11, 12 of the upper
closing element 7 in said position thus form the lateral boundary of the disposal
volume. In the open position, they diverge slightly in the downward direction, thereby
determining the thus widening passage.
[0026] As has already been mentioned, Fig. 3 shows the disposal lock 1 in the exploded state.
In the assembled state, the back wall 26, the front wall 27 and the flaps 11, 12 of
the upper and lower closing element define the passage through the disposal lock.
Furthermore, the disposal lock has side walls 28 which adjoin the front wall 27 and
the back wall 26.
[0027] Although a specific embodiment has been described above for driving the flaps, this
can also be configured in different ways. Thus, it is, for example, also possible
for the tumbler to be driven by means of a tooth sector which is attached thereto,
and which is in engagement with a pinion which is mounted on the shaft of the electric
motor, possibly via a reduction.
