The disclosed subject matter relates to a pedal mechanism and more particularly to a pedal operated bin system comprising the same.
References considered to be relevant as background to the presently disclosed subject matter are listed below:
Acknowledgement of the above references herein is not to be inferred as meaning that these are in any way relevant to the patentability of the presently disclosed subject matter.
Various types of pedal mechanisms and bins comprising the same are known in the art. Some of these are disclosed in the referenced prior art references acknowledged hereinabove. For example, U.S. Pat. No. 8,136,688 is directed to a trash can assembly having an ter shell and a lid pivotally coupled to the shell for movement between an open
sition and a closed position. A foot pedal is operatively coupled to the lid such that
ssing down on the pedal caused the lid to open. A fluid damper is mounted to
rnpen the downward movement of a lid. The damper engages a support surface
eratively coupled to the lid such that the support surface moves in conjunction with
wement of the lid as the lid moves between the open position and the closed position,
d yet the fluid damper is unsecured to the support surface.
Another example is disclosed in U.S. Pat. No. 7,806,285 directed to a trash can assembly ving a lid pivotably coupled to an upper end of an outer shell, and a pivoting pedal
r that is coupled to the lid via a link rod. The closing motion of the lid is dampened by
anter-balancing the closing force of the lid, which can be accomplished by generating
counter-balance force against the pedal bar that is equal to or slightly less than the)
sing force of the lid. The counter-balance force can be made to vary during the)
sing motion of the lid. In addition, the entire link rod can be positioned inside the
erior of the outer shell, and the pivot axis of the lid about the outer shell can also be
sitioned inside the interior of the outer shell.
The disclosed subject matter is directed to a pedal mechanism. The pedal chanism in accordance with the disclosed subject matter can form part of any
ntainer system comprising, for example, a pivotable lid. The pedal mechanism, in
cordance with the disclosed subject matter, facilitates opening of the lid by
nsmission of force applied on a pedal and transmitted to the lid opening mechanism
rough the pedal mechanism of the present subject matter. The pedal mechanism
ilitates pulling of the lid to its open position rather than pushing and lifting of the
me by a lifting mechanism.
In accordance with one aspect of the disclosed subject matter there is disclosed a dal type bin assembly comprising a bin having a top and a bottom, a lid pivotably
ached at a top portion of a rear wall of the bin, and a pedal mechanism disposed at a
ttom portion of the bin, wherein the bin further comprises a lid manipulating member
tending between the lid and the pedal mechanism and wherein the pedal mechanism comprises a pedal provided at a front portion at the bottom portion of the bin, a force
nsmitting system and a connecting element couplable to the lid manipulating member
a rear portion of the bin bottom portion, configured for manipulating the lid between
open and a closed position upon respective operation of the pedal mechanism.
In accordance with an example, the pedal mechanism of the pedal type bin mprises a base lever actuatable by the pedal, the base lever having a first member and
econd member flexibly connected through at least one hinge, wherein each one of the
int member and the second member comprises at least one laterally extending torsion
rs configured to axially support the base lever and connecting it to laterally extending
rallel supporting surfaces and wherein the torsion bars allow swinging of the base
er relative to the supporting surface and wherein the force applied at a frond edge of
front member is transmitted to the rear edge of the rear member.
In accordance with an example of this aspect, the bin and the pedal mechanism a unitary and integral structure. In accordance with another example, the pedal
mechanism and the bin are articulated to each other. In accordance with yet an example,
pedal and the force transmission mechanism are integrally formed. In accordance
th another example, the pedal is detachably attachable to the pedal mechanism.
In accordance with an example, the pedal type bin assembly further comprises a i liner or an inner bin. In accordance with yet an example, the liner is configured to at
ist partially line and cover an inside surface of the bin. In accordance with yet an
ample, the liner is configured to cover the bottom portion of the inside surface of the
a. The liner can be an integral part of the bin or a removable component thereof.
In accordance with another aspect of the disclosed subject matter there is) vided a pedal mechanism. The pedal mechanism in accordance with this aspect
mprises a base lever actuated by a pedal (which can form an integral part of the pedal
chanism or be detachably attachable thereto). The force transmission mechanism
mprises a base lever having a first member disposed at the front and a second lever
tuber disposed at the rear flexibly connected through at least one hinge, e.g. integral
age, and wherein each of the front member and the second member comprise at least
e laterally extending torsion bar configured to axially support the base lever allowing
nnection to lateral supporting surfaces and allowing swinging of the base lever
ative to the supporting surface, and wherein the force applied at a frond portion of the
nat member is transmitted to the rear portion of the rear member. The first member and the second member can be an integral unit interconnected by an integral hinge. In
ordance with another example, the first member and the second member can be)
arate elements configured for articulation one with the other through at least one
iging member.
The pedal mechanism and/or the pedal bin can be formed from any suitable aerial, as plastic, metal, rubber, silicone etc.
In accordance with yet an aspect there is provided a multi-lever rocker actuating chanism comprising a first lever member pivotable about a first axis and a second
Ter member pivotable about a second axis, a front end of the first lever comprising an
eating pedal and a rear end of the first lever is pivotally articulated to a front end of
rear lever; a rear end of the rear lever is configured for articulating to a bottom end
the lid manipulating member having a top end thereof pivotally articulated to a pivot
the rear end of the lid, wherein downward displacement of the actuating pedal entails
oting of the first lever in a first direction and corresponding pivotal displacement of
second lever in an opposite direction, such that the rear end of the second lever
places downwards, resulting in corresponding downwards displacement of the lid
anipulating member, whereby downwards displacement of the lid manipulating
ember in turn entails downwards displacement of the rear lid portion, resulting in
votal displacement of the lid into its open position.
The following parameters can alter the force and displacement factors of the lid tuating mechanism:
The length of the levers;
The positioning of the axes of the levers;
The pre-angular positioning of the levers;
According to a particular configuration of the disclosure, the first axis and the cond axis are substantially parallel to one another;
In accordance with one example, the at least first lever and the at least second ver are connected directly to each other. In accordance with another example the at
ast first lever and the at least second lever are connected through an interconnecting
k. In the case of the latter, the interconnecting link extends between the top rear of
e first lever member and bottom front of the second lever member.
In accordance with one example the axis extending through the first lever and second lever are constituted by torsion bars. In accordance with another example the
are normal axis bars, with no torsioning properties.
Downwards displacement of the lid manipulating member is substantial axial placement, taking place along its longitudinal axis;
The above is the sequence of operation of a normally closed lid, wherein lowing the release of force from the actuating pedal, the lid will spontaneously
place into a normally closed position, under its self weight, upon seizing downward
ce on the actuating pedal
It is appreciated that the number of levers in the sequence of the multi-lever angement can be any pair number.
Biasing of the system into dampened closing of the lid can be facilitated by lizing a torsion mechanism articulated to one or more of the pivoting locations of the
ilti-lever train.
In order to better understand the subject matter that is disclosed herein and to emplify how it may be carried out in practice, embodiments will now be described,
way of non-limiting examples only, with reference to the accompanying drawings, in
rich:
accordance with an example of the disclosed subject matter in a closed position,
spectively;
e bin of
d the lid manipulating mechanism at the closed position;
ith the disclosed subject matter;
In accordance with this example, the bin 110 and the pedal mechanism 130 are integrally formed together. Optionally, the bin and the pedal mechanism can be separate members. The bin 110 with the pedal mechanism 130 are injection molded from a plastic material. It will be appreciated that other materials and methods of manufacturing are envisioned. Material for the bin can be e.g. metal, foil covered plastic etc. the pedal mechanism can also be formed from other materials, e.g. metal, wood, rubber etc. The lid 120 and the lid manipulating member 118, which are in form of a strap in the current example, are in turn formed as an integral unit in an injection ding process. The material used or the formation of the lid manipulating member
8 is sufficiently flexible to facilitate deformation thereof upon manipulation without
tting unnecessary stress on the strap which might result in cracking or snapping of the
ne. It will be appreciated that the lid and the lid manipulating member can be)
crate and made from different materials and the lid manipulating member can have
rious shapes as desired from a single slim rod to a broader strap or a more complex
ucture configured to connect the lid to the pedal mechanism. For example, the lid
nipulating member can be a metal rod or a metal strap.
The lid 120 is configured for articulation to the bin 110 through a hinge element 2 which provides for the pivotal movement of the lid 120 with respect to the bin 110.
will be appreciated that the lid can be articulated to the lid manipulation member e.g.
sough an integral hinge. The free end 119 of the lid manipulation member 118 is)
vided with a socket 124 configured for detachable attachment to the connecting
inent 155, forming a male to female fixed connection. Other types of connections are
visioned, e.g. a snap type connection, adhesion, welding, hinged connection, etc. or
egration of the parts in one single unit.
Referring now to 0 comprises at its bottom 114 the pedal mechanism 130 which in this example forms
integral part of the bin. The pedal mechanism 130 comprises a base lever 135
tuated by a pedal 132 (which in this example forms an integral part of the pedal
echanism however it will be appreciated that this element can be detachably
achable or a separate member fixedly fitted thereto). The base lever 135 has a first,
nt member 136 and a second, rear member 138 flexibly connected through a hinge
10, in this example an integral hinge. It will be appreciated that the first member and
e second member can be separate members interconnected through at least one hinge
le front member 136 has a fore end connecting to the pedal 132 and a rear end 137
nfigured for connecting to the second member 138, a top surface 139 and a bottom
rface (not shown); the second member 138 has a fore end 139 configured for
nnecting to the first member 136 and a rear end fitted with a connecting element 155
hich is an outward protrusion configured to fixedly engage the socket 124 of the
anipulating strap 118. The second member 138 further has a top surface 141 and a
ttom surface (not shown). The integral hinge 140 extends diagonally from the bottom surface of the fore end of the second member 138 and to the top of the rear edge of the
st lever member 136. In the present example, the connection between the top rear end
the first member 136 to the hinge 140 at the bottom fore end of the second lever
amber 138 extends through another integral hinge 142. In the illustrated example, the
st member and the second member are diagonally connected by an intermediate
erconnecting link in the form of a hinging strap 145, connecting the members through
hinges 140 and 142. Thickness of the hinging strap 145 is in this case smaller than
it of the lever members and larger than that of the hinges constituted by thinned out
rtions (e.g. integral hinges). However it will be appreciated that the connection can be
ide using alternative connecting members, e. g., one or more connecting strings etc.
directly to each other by various means, e.g. an integral hinge.
The base lever 135 is connected to the base bottom through laterally extending sion bars 162A, 162B, 164A and 164B configured to axially support the base lever
5 allowing connection to lateral supporting surfaces 160A and 160B extending from
d in parallel to the side walls of the bin. This allows controlled swinging of the base
er 135 (and if present of the pedal member 132) relative to the supporting surfaces
ien the force applied at a frond edge of the front member 136 is transmitted to the rear
ge of the rear member 138, as will be discussed hererinafter. The torsion bars
nnected to the supporting surfaces have thus a restrained warping at the root which
ows the base lever members 136 and 138 to swing back to their initial position when
force is released. It will be appreciated that a regular axis can be used to manipulate
levers.
As seen in ction. However, it will be appreciated that bars having another cross section are
visioned, as exemplified in
shaped bars, respectively, as well as I, U or other shapes of bars can be used as
rsion axis bars.
The operation of the lid 120 and the pedal mechanism 130 will be discussed ith reference to drawings in
sembly 100, the pedal 132 is pressed down in the direction of arrow D, this exertion
force is in turn transmitted by the pedal mechanism 135 to downward pulling of the
1 manipulating strip 118 towards the bottom 114 of the bin 110 in the direction of
row d. substantially parallel to the direction D, which in turn causes the lid 120 to pivot (arrow p) in a rearward direction, thus opening the lid 120 and allowing access to
inner space S of the bin 110. The pedal mechanism 130 allows this transmission of
ce via the base lever 135 and facilitated by the torsion bars 162AB and 164AB
ping the base lever attached to the bin bottom.
By pressing the pedal member 132, the rear end of the front lever member 136 is shed up in the direction of arrow B with the torsion bars 162A and 162B supporting
same and extending along the same axis X which are warped or twisted in the
unter clockwise direction of arrow A, i.e. towards the pressed pedal. This action, in
n, pulls the front edge of the rear lever member 138 upward (in the direction B)
ough the strip 145 which is pulled up by the rear end of the first member. Facilitated
the hinge 140, the structure is rendered flexible and cracking of the plastic is
oided. The torsion bars 164A and 164B twist in the clockwise direction, i.e. opposite
ection from the bars 162A and 162B, causing this upward movement of the front end
the rear lever member 138 to translate into the downward movement of the rear end
the rear lever member, i.e. the connecting element 155, tilting the second member.
tis downward movement of the connecting element pulls on the strip member 118,
using the lid 120 to pivot and open the bin 110, as seen in
dal 132, will reverse the action of the pedal mechanism 135 via the torsion bars, thus)
sing the lid 120 over the bin 110. Due to the flexibility and the elasticity of the
rsion bars and the hinges connecting the base lever member, the action can be
peated numerous times, without causing any structural damage.
It should be appreciated that the lid 120 can be opened by directly pivoting it irection of arrow P), however in such a case the pedal mechanism 130 will not be
tuated.
As described herein, in the illustrated example the pedal mechanism 130 and the n 110 are molded as a unitary and integral structure. It will be appreciated however
at the pedal mechanism can be a separate part fixedly attached to the bin. As best seen
ember 132 are designed so as not to protrude beyond the boundaries of the bin front
3B and rear walls 111AB. As indicated above, the front wall is provided with an
ening 180 allowing access to the pedal 132. It will be appreciated that in accordance
ith another example, the pedal can extend outside the bin boundaries.
The structural features of the bin of the illustrated example allow for ease of) lding and safe storage as well as nesting within a like bin. Furthermore, the sidewalls
the bin are slightly tapered thus allowing the nesting within a like bin with the lid
her in an open position or removed from the bin. This nesting provides, e.g. for a
mpact transportation. It will be appreciated that the shape of the bin can vary. It can
cylindrical, oval or any polyhedral shape.
To protect the pedal mechanism and to prevent soiling thereof and of the surface derneath thereof, the pedal type bin 100 assembly further comprises a bin liner 200,
in
mpletely. The outer edges of the liner are provided with hook-like extensions 220,
nfigured for engaging corresponding protrusions over the supporting walls 160A and
0B on the bin bottom 114. As seen further in
wardly extending concave wall portion 210 (also seen in
ening 180 whilst also allowing sufficient space to guide the users' foot to the pedal
2. The liner rests on the supporting walls 160A and 160B extending at the inner
rface of the bin bottom. The height of the supporting surfaces 160A and 160B is high
ough to prevent the bottom surface of the liner from unintentional contact with the
dal mechanism. It will be appreciated that the liner can constitute an inner bin, e.g. to
ver substantially the entire inner surface and the side walls of the bin. The liner and/or
e inner bin can be removable or fixedly attached to the bin.
Turning now to accordance with an example of the disclosed subject matter. The pedal mechanism 300
similar to the one described with reference to
siding in that this mechanism is independent of any structure. It will be appreciated
at such a mechanism can be used in conjunction with any type of structure having a
over or a portion of a cover manipulable between a closed and an open position. While
the previous example the torsion bars 162AB and 164AB were restrained by the
pporting surfaces extending from the side walls of the bin, as seen in the illustrated
ample, the laterally extending torsion bars configured to axially support the base lever
e connected to and restrained by two parallely extending supporting surfaces.
The pedal mechanism of ements functionally corresponding to elements in the previous example upped by 300.
he pedal mechanism 300 comprises a base lever 335 actuated by a pedal 332 (which in this example forms an integral part of the pedal mechanism however it will be
preciated that this element can be detachably attachable or a separate member fixedly
ed thereto). The base lever 335 has a first, front member 336 and a second, rear
tuber 338 flexibly connected through a hinge 340, in this example an integral hinge.
will be appreciated that the first member and the second member can be separate
tubers interconnected through at least one hinge. The front member 336 has a fore
d connecting to the pedal 332 and a rear end 337 configured for connecting to the
ond member 338, a top surface 339 and a bottom surface (not shown); the second
tuber 338 has a fore end configured for connecting to the first member 336 and a rear
d fitted with a connecting element 355 which is an outward protrusion configured to
engage a manipulating member. Other types of connections are envisioned, e.g. a
ap type connection, adhesion, welding, hinged connection, etc. or integration of the
rts in one single unit. It will be appreciated that the mechanism can be devoid of this
nnecting member.
The second member 338 further has a top surface 341 and a bottom surface (not own). The integral hinge 340 extends diagonally from the top surface of the first
ember 336 to the bottom surface of the second member 338. In the present example,
connection between the top rear end of the first member 336 to the hinge 340 at the
ttom fore end of the second lever member 338 extends through another integral hinge
2. In the illustrated example, the first member and the second member are diagonally
nnected by an intermediate hinging strap 345, connecting the members through the
ages 340 and 342. Thickness of the hinging strap 345 is smaller than that of the lever
embers and larger than that of the hinges constituted by thinned out portions (e.g.
tegral hinges). However it will be appreciated that the connection can be made using
ernative connecting members, e. g., one or more connecting strings etc.
The base lever 335 is connected laterally to two supporting surfaces 360A and 0B extending in parallel by torsion bars 362A, 362B, 364A and 364B configured to
ially support the base lever 335. This allows controlled swinging of the base lever 335
nd if present of the pedal member 332) relative to the supporting surfaces when the
rce applied at a frond edge of the front member 336 is transmitted to the rear edge of
e rear member 338. The torsion bars connected to the supporting surfaces have thus a
strained warping at the root which allows the base lever members 336 and 338 to
ving back to their initial position when the force is released.
The torsion bars 362 have a shape of cross (+) in their cross section. However, it be appreciated that bars having another cross section are envisioned, as exemplified
well as I, U or other shapes of bars which can be used as torsion axis bars.
