BACKGROUND

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, US8136688 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 tnpen 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 )vement of the lid as the lid moves between the open position and the closed position, i yet the fluid damper is unsecured to the support surface.

Another example is disclosed in US7806285 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 unter-balancing the closing force of the lid, which can be accomplished by generating ;ounter-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.

DETAILED DESCRIPTION OF EMBODIMENTS

Figs. 1A and IB illustrate a pedal type bin assembly generally designated 100. The assembly 100 comprising a bin 110 having a top 112 and a bottom 114, a pivotably attached lid 120 at a rear end 116 of the bin top 112 and a pedal mechanism generally designated 130 and best seen in Fig. 3 extending at the bottom 114 of the bin 110. The bin 110 further comprises a lid manipulating member 118 extending between the lid 120 and the pedal mechanism 130. The bin comprises side walls 111A and 111B, rear wall 113A bearing the lid 120 at its top and a front wall 113B provided with an opening 180 for allowing access for operating the pedal mechanism 130, e.g. by users' foot. The pedal mechanism 130 comprises a pedal 132 provided at a front side 115 at the bin bottom 114, a force transmitting system 150 (seen in Fig. 3) and a connecting element 155 couplable to the lid manipulating member 118 at the rear side 117 of the bin bottom 114, configured for manipulating the lid 120 between an open and a closed position upon respective operation of the pedal mechanism 130.

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 >lding 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 jarate 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 mipulating 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. •ough an integral hinge. The free end 119 of the lid manipulation member 118 is jvided with a socket 124 configured for detachable attachment to the connecting :ment 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 Fig. 3, the bin 110 is illustrated viewed from the top. The bin 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 schanism 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

[0, 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 mfigured for connecting to the second member 138, a top surface 139 and a bottom xface (not shown); the second member 138 has a fore end 139 configured for innecting 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 itttim 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 ;mber 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 rsion bars 162 A, 162B, 164 A and 164B configured to axially support the base lever 5 allowing connection to lateral supporting surfaces 160 A 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 len 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 s force is released. It will be appreciated that a regular axis can be used to manipulate 2 levers.

As seen in Fig. 4, the torsion bars 162 have a shape of cross (+) in their cross ction. However, it will be appreciated that bars having another cross section are visioned, as exemplified in Figs. 5A to 5C, showing a y-shaped, a straight line or an -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 Figs. 3, 6B, and 7. To open the lid 120 of the bin 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 i 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 sping 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 162 A and 162B supporting ϊ 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) rough 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 rection 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, lis 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 Fig. 6B. Releasing the dal 132, will reverse the action of the pedal mechanism 135 via the torsion bars, thus jsing 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

Figs. 3 and 7, the pedal mechanism, in the illustrated example, including the pedal 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 tnpact 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, sn in Fig. 8A. This liner 200 fits above the pedal mechanism 130, covering it 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 Fig. 8B, the liner is provided with an wardly extending concave wall portion 210 (also seen in Fig. 9) which closes the lening 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 Figs. 10A and 10B, there is provided a pedal mechanism 300 in cordance with an example of the disclosed subject matter. The pedal mechanism 300 similar to the one described with reference to Figs. 3 and 6B with the difference 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 >ver 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 ipporting 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 Figs. 10A and 10B will now be described, with ements functionally corresponding to elements in the previous example upped by 300. tie 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 predated 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 :mber 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 snbers 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 ;mber 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 its 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 smber 336 to the bottom surface of the second member 338. In the present example, 3 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 tiges 340 and 342. Thickness of the hinging strap 345 is smaller than that of the lever ambers 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 lernative connecting members, e. g., one or more connecting strings etc.

The base lever 335 is connected laterally to two supporting surfaces 360A and •OB 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 tid 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 ring 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 11 be appreciated that bars having another cross section are envisioned, as exemplified Figs. 5A to 5C, showing a y-shaped, a straight line or an X-shaped bars, respectively, well as I, U or other shapes of bars which can be used as torsion axis bars.
