Description
[0001] The present patent application for industrial invention
relates to a trash bin comprising a frame that supports and guides
a waste holding bucket that can be indirectly lifted by means of a
pedal, pivoted at the bottom of the said frame, which is also
designed to support the folding lid that closes the trash bin.
[0002] The trash bin of the invention is an evolution of the models
of trash bins obtained by moulding of plastic material, composed of
an external fixed bucket that contains and conceals a mobile waste
holding bucket sliding in up-down direction that, during the
ascending travel, overturns the closing lid of the external fixed
bucket hinged on the back side of the opening of the said
bucket.
[0003] The lid is overturned upwards and backwards when it suffers
the interference of the upper border of the internal bucket during
the ascending travel.
[0004] The internal bucket is lifted by means of a pedal situated
under the wall of the said bucket and pivoted to the bottom wall of
the external bucket, from which the said pedal protrudes
frontally.
[0005] More precisely, the bottom wall of the external bucket is
provided with a central notch with U-shaped profile, in which the
pedal is centred and pivoted in a central point in such a way to
oscillate and swing around a horizontal axis.
[0006] When the operator exerts pressure on the ending part of the
pedal that protrudes on the front of the trash bin--thus lowering
the said end--the opposite end of the pedal rises, exerting an
upward force that lifts the internal bucket that, during the
ascending travel, exerts an overturning thrust on the lid
above.
[0007] A trash bin of this type is disclosed and illustrated in the
patent for utility model No. 248367 registered by the same
applicant.
[0008] The primary purpose of the present invention is to design a
trash bin that, although having the same operation modes and
advantages of the aforementioned models of trash bin, is
characterised by lower weight and lower manufacturing cost, with
the same capacity of the waste holding bucket and the same moulding
material.
[0009] The primary purpose has been achieved by the trash bin of
the invention, whose main peculiarity consists in the innovative
structural configuration, according to which the waste holding
bucket is supported and guided by a frame, to which both the
lifting pedal of the said bucket and the folding lid of the trash
bin are pivoted, which is sized and shaped in such a way to close
the opening of the said bucket.
[0010] The lower weight and lower cost of the trash bin of the
invention derive from the fact that, because of the reduced mass,
the supporting frame has a lower weight and a lower manufacturing
cost than the external bucket of the known models of trash
bins.
[0011] More precisely, the said frame comprises a base tub designed
to house the bottom area of the waste holding bucket, with at least
a back protruding wall pivoted on top to the folding lid of the
trash bin.
[0012] The lifting pedal of the waste holding bucket is pivoted
with respect to a horizontal axis in the centre of the bottom wall
of the said base tub. The up-down travels of the waste-holding
bucket are guided by the said frame, which is suitably provided
with centring and guiding means for the waste-holding bucket.
[0013] The secondary purpose of the present invention consists in
devising a trash bin characterised by lower weight and cost than
the known models of the same type, which has the same external
appearance as the known models of trash bins in closed
configuration, regardless of the fact that in the trash bin of the
invention the supporting frame does not conceal the waste holding
bucket, which remains always visible, unlike the known models of
trash bins, in which the internal waste holding bucket is concealed
and contained in the external bucket.
[0014] In order to achieve the second purpose , the trash bin of
the invention uses a waste holding bucket that is provided on the
external surface with lowered shaped areas situated in such a way
to exactly house the supporting frame, whose profile is exactly
matched and aligned with the one of the lowered areas, so that the
external visible surface of the waste holding bucket is perfectly
connected with the external visible surface of the supporting
frame, the two visible surfaces being only divided by a thin
separation line that is perceived by the observer as a thin
aesthetical surface incision rather than as a line of physical
separation between the two components.
[0015] In other words, the external surface of the frame is
visually incorporated, without interruption, into the external
surface of the waste holding bucket, giving the impression of a
traditional trash bin, of the type composed of an external bucket
that contains and conceals the waste holding bucket.
[0016] For purposes of clarity the description of the trash bin
according to the present invention continues with reference to the
enclosed drawings, which are intended for purposes of illustration
only and not in a limiting sense, wherein:
[0017] FIG. 1 is an axonometric front view of the trash bin of the
invention with closed lid;
[0018] FIG. 2 is an axonometric front view of the trash bin of the
invention with open lid;
[0019] FIG. 3 is an exploded axonometric view of the waste holding
bucket separated from the supporting and guiding frame;
[0020] FIG. 4 is an axonometric front view of a different
embodiment of the trash bin of the invention with open lid, in
order to show the peculiarity of the said embodiment, which differs
from the previous one only in the presence of a parallel pair of
waste holding buckets for differentiated waste collection.
[0021] With reference to FIGS. 1 to 3, the trash bin of the
invention (1) is provided with a lid (2) that is indirectly lifted
by means of a lifting pedal (3) whose end can be accessed from the
centre of the front of the base of the trash bin (1).
[0022] The said trash bin (1) comprises a supporting and guiding
frame (4) for a waste holding bucket (5) that slides in up-down
direction with respect to the frame (4), which is provided with a
back wall (4a) where the said frame (4) reaches its maximum
height.
[0023] The lid (2) is hinged on top of the back wall (4a) of the
frame (4) and is designed to be overturned upwards and backwards
when the bucket (5) is lifted from the ordinary rest position, in
which the upper border (5a) of the bucket (5) is situated at a
height immediately below the lid (2), which is sized and shaped in
such a way to close and exactly embrace the opening of the bucket
(5), as shown in FIG. 1.
[0024] The frame (4) is composed of a tub (V) designed to receive
the bottom area of the bucket (5); the wall (4a) protrudes on the
back of the tub (V), whose bottom wall (4b) is pivoted to the
lifting pedal (3).
[0025] With reference to FIG. 3, it must be noted that the frame
(4) has a variable height, reaching a maximum value on the back to
allow the lid (2) to be placed over the opening of the bucket (5)
in closed position.
[0026] The external surface (5c) of the bucket (5) is provided with
a lowered area (A) defined by a step (G) having the same profile as
the profile (4c) of the frame (4), which can be perfectly combined
with the said lowered area (A).
[0027] More precisely, when the trash bin is closed, the lowered
area (A) is completely concealed by the walls of the frame (4),
with the profile (4c) aligned with the step (G), as shown in FIG.
1.
[0028] In view of the above, when the trash bin (1) is closed, the
frame (4) practically supports the bucket (5), whose weight is
discharged on the profile (4c) of the walls of the frame (4).
[0029] According to the present invention, when the trash bin is
closed, the visible part of the external surface (5c) of the bucket
(5) and the walls of the frame (4) are always aligned perfectly on
the step (G), giving the impression to be a single continuous
surface that coincides with the external surface (5c) of the bucket
(5) with a merely decorative thin line (L), although the line (L)
is not a decorative line, but the separation line (L) between the
external surface (5c) of the bucket (5) and the wall of the frame
(4).
[0030] The camouflage impression and effect are stronger if the
frame (4) and the bucket (5) have the same surface finish and two
different colours.
[0031] In such a case, the separation line (L) is interpreted as a
line dividing two areas with different colour of the lateral
surface (5c) of the bucket (5), which is interpreted by the
observer as the external bucket of a trash bin of known type, in
which the waste holding basket is concealed and contained in an
external bucket.
[0032] Finally, attention is drawn on the fact that the frame (4)
also comprises means that specifically consist in vertical ribs (6)
to guide and centre the up-down travels of the bucket (5).
[0033] FIG. 4 illustrates a different embodiment of the trash bin
of the invention that, as mentioned above, differs from the
previous one only in that it is provided with a parallel pair of
waste holding buckets for differentiated waste collection.
[0034] In particular, the said pair of buckets comprises a front
bucket (50) and a back bucket (51) with total capacity equal to the
said single bucket (5).
[0035] In fact, the parallel pair of buckets (50 and 51) can be
imagined as the result of a division of the same bucket (5) in two
parts, a front part and a back part.
[0036] Only the back bucket (51) is subject to the interference of
the lifting pedal (3), so that the lid (2) is overturned only by
the back bucket (51), whose up-down travels are guided by the frame
(4).
[0037] On the contrary, the front bucket (50) remains still,
supported and centred in the tub (V) of the frame (4), whose
profile (4c) is aligned with a step (G) obtained on the external
walls of both buckets (50 and 51), which are provided on the
external surface with a lowered area defined by the said step (G),
having the same profile as the profile (4c) of the frame (4), in
such a way that, when the trash bin is closed, the lowered area is
completely concealed by the walls of the frame (4), with the step
(G) being perfectly aligned with the profile (4c) of the frame
(4).
