Claims
1. Blocking device for a lid (4) on a waste container,
characterized in the device (6) comprising a hook (1) the underside
of which being arranged above the hinge part (7) of the lid when
the lid (4) is closed, the hook (1) being arranged on an elastic
bar (2) being adapted to be bent when the hinge part (7) is pressed
towards the underside of the hook (1), and that the upper side of
the hook (1) is inclined to receive and hold the weight of the
hinge part (7), however allow the hinge part (7) to pass by the
hook (1) as the bar (2) is bent when the hinge part (7) is pressed
against the hook (1).
2. Device according to claim 1, characterized in the blocking
device (6) being adapted to be secured to a waste container (5) for
example by screws, glue, rivets etc.
Description
[0001] The present invention is related to a blocking device for a
waste container lid.
[0002] Most waste containers are provided with lids being hinged to
the container body. Such the lids may be turned freely up to
270.degree.. As smaller containers are high and narrow and
therefore relatively unstable, this causes a well known problem,
namely that the containers overturn in wind or of other reasons
resulting the content being scattered around and tuned into a
meeting place for insects and carrion birds.
[0003] This problem is causes serious pollution problems as well as
decreasing the aesthetic value of the surroundings of the
container. A practical solution to avoid this has been to place a
stone or some other heavy subject on the container lid. This,
however, means that persons have to lift the stone away before
placing something in the container and in such cases the stones not
always are placed on the lid after closing it.
[0004] With increasing use of source separation and thereby the
number of containers as such, the problem is naturally
increasing.
[0005] There exists a need for a mechanism ensuring that the lid is
not blown up by the wind, however on the other hand that the lid
very easily can be opened by the users. Such a mechanism also must
ensure that the requirements of the public cleansing authority
completely are fulfilled in such a way that the lid is opened
automatically when the waste containers are turned around to be
emptied into the refuse collection vehicles.
[0006] The above objects are achieved with the blocking device
according to the present invention as defined with the features
stated in the claims.
[0007] The drawing discloses in FIG. 1 a side view from behind of
one embodiment of the blocking device according to the present
invention, FIG. 2 discloses a side view of the embodiment in FIG.
1, FIG. 3 discloses a front view of the blocking device, FIG. 4
discloses a ground view of the device, FIG. 5 discloses part of a
waste container including the device and with the lid closed, FIG.
6 discloses schematically how the blocking device prevents the lid
to open when exposed to wind, FIG. 7 discloses that the lid in open
position abuts the blocking device and FIG. 8 discloses an upper
part of a waste container with the lid in closed position.
[0008] The blocking device 6 according to the present invention
comprises a hook I on a bar 2 which age is connected with the
securing part 3 for securing the device to the waste container,
preferably to the hinge part 8 of the waste container 5. Preferably
the hook 1, the bar 2 and the secureing part 3 are integrated in
one part. Furthermore the locking device 6 according to the
invention principally also may be formed as an integrated part of
the waste container.
[0009] It is however substantial for the use that the blocking
device 6 is formed of a material which is elastic on one hand and
on the other hand is able to withstand cold weather with may
degrees below zero as well as varm weather with many degrees above
zero, as well as the tough handling such containers are exposed
to.
[0010] When the lid 4 is closed as shown in FIG. 5, the blocking
device will not influence the lid as such. However, when the lid 4
is opened just a little, the hinging part 7 of the lid will be
pressed against the underside of the hook 1 and prevent the lid to
be opened. This blocking is sufficient to prevent that the wind is
opening the lid 4 and also prevents the lid 4 to be opened in case
the waste container 5 is tipped over.
[0011] If, however, a press force in the range of 2 or 3 kg or
more, is exerted against the lid 4, the bar 2 of the blocking
device 6 is bent outwardly and thereby assuring that the hinge part
7 of the lid is slipping past the hook 1, whereby the lid 4 can be
opened by a user without problems. This also ensures on the other
side that the lid 4 is opened when the waste container 5 is turned
bottom up to be emptied to be emptied in a refuse collection
vehicle, as the content of the container will press against the
lid, causing the lid to be opened.
[0012] When the lid 4 is lifted past the blocking device 6 and
thereafter is dropped, the hinging part 7 of the lid 4 will as
disclosed in FIG. 7, abut against the upper side of the hook 1 of
the blocking device 6 and be maintained in this position in such a
way that a user can drop waste down into the container,
[0013] It is further a known problem that the lid is falling
270.degree. backwards in case the container 5 as such is not placed
in front of a wall. This problem is solved by the device according
to the present invention as the lid may rest in an open position
against the blocking device 6. The user, however, very easily can
press the lid 4 downwardly by a relatively small force.
[0014] As specially disclosed in FIG. 4, the hook 1 is bevelled in
such a way that a lid approaching the blocking device 6 will a
certain speed, will bend the device and be pressed past the device
until abutment on the container 5. This also will be the case when
the container is put down after having been emptied into a refuse
collection vehivle.
[0015] In case the lid is pressed downward against the hook 1 from
the position in FIG. 7, the bar 2 will be bent and let the hinge
part 7 of the lid 4 pass, the lid 4 thereby taking the position
disclosed in FIG. 5.
[0016] The blocking device 6 preferably is symmetrically shaped as
disclosed especially in FIG. 4, thereby enabling the device to be
placed on one or the other side or possibly on both sides of the
waste container 5. For larger waste containers it will be natural
to use two blocking devices 6.
[0017] The blocking device according to the invention easily can be
secured to existing waste containers from different manufactures,
by the use of screws, double-sided tape, glue or such. The blocking
device also can be formed as part of the waste container as such or
as put of the lid. As such separate blocking devices can be secured
to the lid depending on the specific type of waste container.
[0018] With a blocking device 6 secured at each side of the waste
container, it is to a very large extent secured that the plug
holding the hinge part 7 of the lid to the hinge part of the waste
container, not easily is pressed out by side forces caused by users
or by the wind as the devices 6 provide a locking function.
