Abstract

A trashcan can be configured to fit into the corner of a room. The trashcan can have a foot pedal that is connected to the lid of the trashcan such that a user can open and close the lid with the foot pedal. The trashcan can be configured such that the lid pivots about an axis that is generally parallel to one of the walls when the trashcan is positioned in the corner of a room. Additionally, the trashcan can include a dampening mechanism which includes two apertures having axes that are skewed relative to one another. This allows the pedal bar and associated lifting rod mechanisms to pivot about the appropriate axes to provide smooth and low friction operation.

Description

• This application is a non-provisional of and claims benefit under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 60/969,502, filed Aug. 31, 2007, the entire contents of which is hereby expressly incorporated by reference.
BACKGROUND OF THE INVENTIONS
• 1. Field of the Inventions
• The present inventions relate to receptacles, such as trashcans, and more particularly, to receptacles that are configured to fit into the corner of a room.
• 2. Description of the Related Art
• Receptacles and other devices having lids or doors are used in a variety of different settings. For example, in both residential and commercial settings, trashcans and other devices often have lids or doors for protecting or preventing the escape of the contents of the receptacle. In the context of trashcans, some trashcans include lids or doors to prevent odors from escaping and to hide the trash within the receptacle from view. Additionally, the lid of trashcan can help prevent contamination from escaping the receptacle.
• Many designs of such trashcans include a pedal actuated lid. In these designs, a user can step on a pedal to open the lid. Additionally, many of these designs also include a damper, such as a rotary damper or a gas damper, for slowing the closing motion of the lid and thereby preventing a loud slamming noise when the lid is moved from an open position to a closed position.
SUMMARY OF THE INVENTIONS
• As aspect of at least one of the inventions disclosed herein includes the realization that with regard to receptacles that are shaped to be placed in the corner of a room, an advantage can be achieved by mounting the lid such that when it is opened, it lies approximately flat against one of the walls in a corner of the room. For example, such a trashcan have a lid that is hinged along its right side edge such that when the lid is opened, it lies generally flat against the wall on the right side of the can, i.e., the wall that would be on the left side of a user facing the front of the trashcan. In this position, the lid of the trashcan can act as a backboard when a user throws a piece of trash into the trashcan. Additionally, because this lid would be oriented on the left side of a user facing a trashcan, the backboard use of this lid is convenient for a user because most users are right-handed. A right-handed user would tend to throw a piece of trash across the front of their body toward the left side of their body. As such, the lid would be in a proper orientation to act as a backboard, thereby preventing trash from staining the wall.
• Thus, in accordance with an embodiment, a trash can comprise a lower portion and a wall extending upwardly from the lower portion and defining a cavity, the wall defining a generally triangular cross-section with left and right sides joined at a first corner and extending generally normal to each other and a front side connecting distal ends of the left and right sides. A lid can be configured to close an upper end of the cavity defined by the wall. A hinge can be configured to allow the lid to pivot between open and closed positions, the hinge extending along an axis generally parallel to the right side and being mounted in the vicinity of an upper portion of the right side.
• Another aspect of at least one of the invention herein includes the realization that a damper member can be provided with two apertures oriented in a skewed relation to one another so as to allow the damper to be mounted in an appropriate location to provide a balanced load on the pedal and provide a smooth, low-resistance, attachment for operating the lid opening mechanism. For example, in some embodiments, a trashcan can be generally triangular or pie-shaped with one corner of the triangle disposed toward a corner of a room and the pedal projecting outwardly at roughly 45° from that corner. In this orientation, the damper can be located in a portion of the trashcan adjacent the corner and oriented such that it is generally symmetrically oriented relative to the pedal. This provides a more optimum placement and load generation against the movement of the pedal and the associated lid. With the lid hinged to one of the sides of the trashcan adjacent a wall of the room, a lifting rod connecting an end of the pedal mechanism to the lid will pivot about an axis that is skewed relative to the aperture connecting the damper to the pedal. Thus, by providing another aperture skewed relative to the main aperture, for connecting the lifting rod to the damper, the lifting rod can operate in a smoother fashion.
• In accordance with another embodiment, a trash can comprise a lower portion and a wall extending upwardly from the lower portion and defining a cavity. A lid can be disposed at an upper end of the wall and can be configured to be movable between an open position in the closed position. A pedal actuator assembly can be configured to allow a user to open and close the lid. A damping mechanism can be configured to slow the movement of the lid from the open position toward the closed position. The dampening mechanism can comprise a first member having first and second apertures skewed relative to each other. Additionally, the pedal actuator assembly can comprise a pedal bar having a first end connected to the first aperture and a link member having a first end connected to the second aperture.
• In accordance with yet another embodiment, an air damper can comprise a housing defining an inner bore, a piston configured to reciprocate within the bore, and a piston rod connected to the piston. The piston rod can comprise first and second apertures extending along first and second axes, respectively, the first and second axes being skewed relative to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
• The embodiments of a receptacle with a lid configured to fit into a corner of a room is disclosed in the context of a trashcan. The inventions disclosed herein are described in the context of a trashcan because they have particular utility in this context. However, the inventions disclosed herein can be used in other contexts as well, including, for example, but without limitation, large commercial trashcans, food containers, and/or other types of storage devices, actuators, linkages for actuators, pistons, etc.
• The figures illustrate embodiments of areceptacle10. Thereceptacle10 can include anouter shell12 and an inner liner14 (FIGS. 3-5) adapted to be retained within theouter shell12.
• Theouter shell12 can be optionally supported on abase16. Anupper support frame18 can be secured to the top of theouter shell12. Thesupport frame18 can be made from the same or a different material from that used to form the outer shell.
• Theouter shell12 and thesupport frame18 can be made from any material, such as, but without limitation, aluminum, steel, stainless steel, plastics, etc. Additionally, as noted above, theframe18 can be made from a different material from that used from theshell12.
• Theouter shell12 can be formed in any configuration. The exemplary, non-limiting embodiment illustrated inFIG. 1 includes ashell12 having a generally three-sided triangular or pie-shaped configuration with afront wall20, a right-side wall22, and a left-side wall24. Theliner14 can have generally the same or a different shape, roughly complimentary to the shape of theouter shell12.
• Additionally, in the illustrated embodiment, the transitions between thewalls20,22,24, are generally rounded. However, this is merely one optional configuration. Theouter shell12 can have sharp corners between thewalls20,22,24 and/or other configurations.
• Alid26 can be pivotally connected to an upper edge of theshell12 or theframe18. In the illustrated embodiment, thelid26 can be hinged to theframe18 with ahinge device28. Additionally, as illustrated inFIGS. 1 and 2, thelid26 is hinged to the portion of theframe18 disposed above the right-side wall22 with thehinge device28. Thehinge device28 can be any type of hinge, including, for example, but without limitation, two halves pivotally connected by a hinge pin. However, other configurations can also be used.
• With continued reference toFIG. 2, thelid26 can also include abracket30, configured to connect thelid26 to a lifting mechanism, described in greater detail below, for opening and closing thelid26. In some embodiments, thebracket30 can include afirst leg32 connected to thelid26 and asecond leg34 connected to a liftingrod36. In some embodiments, theleg34 can include an aperture for receiving an upper end of the liftingrod36.
• As such, when the liftingrod36 is pushed upwardly, the upper end of therod36 presses against the aperture, and thereby pivots thelid26 upwardly about thehinge28. Similarly, as thelid26 closes, the liftingrod36 can fall together with theleg34 of thebracket30.
• Additionally, in some embodiments, thereceptacle10 can include alid locking mechanism38 configured to allow a user to lock thelid26 in an open position (illustrated inFIG. 2). In some embodiments, thelocking mechanism36 can be in the form of a simple pivoting member. For example, in the illustrated embodiment, the liftingrod36 andleg34 can move reciprocally through anaperture40. When theleg34 is in the raised position, as illustrated inFIG. 2, thelocking mechanism38 can be slid under a portion of theleg34, thereby preventing theleg34 from passing downwardly through theaperture40. As such, thelocking mechanism38 locks thelid26 in the open position. However, other configurations can also be used to form a locking device.
• Theframe18 can also include a retaininglip42 extending around an upper inner periphery of theframe18. Thelip42 can be configured to engage with a corresponding lip on an outer surface of theliner14 and thereby support the weight of theliner14 and any contents thereof.
• Theframe18 can also include finger recesses44,46 shaped in size to allow a user to easily insert their fingers below the upper lip on the outer surface of theliner14, thereby allowing the user to easily lift the liner out of thereceptacle10. In some embodiments, therecesses44,46 can be disposed on opposite sides of thefront wall20 of thereceptacle10. However, other configurations can also be used.
• Optionally, thereceptacle10 can also include anaperture48 in any one of thewalls20,22,24 configured to allow a user to insert their fingers through theaperture48 and thereby carry or move thereceptacle10. In the illustrated embodiment, theaperture48 is provided onwall22, near the upper end of theshell12, below theframe18. However, other positions can also be used.
• With reference toFIGS. 1 and 3, thereceptacle10 can also include afoot pedal assembly50 configured to cooperate with the liftingrod36 to open and close thelid26. Thefoot pedal assembly50 can include afoot pedal portion52 and apedal bar54.
• Thepedal bar54 can be pivotably coupled to thereceptacle10, for example, using afulcrum rod56, as is well known in the art. As such, thefulcrum rod56 can define a pivot axis located at about a center of thepedal bar54. In some embodiments, the pivot axis can be spaced from the center of gravity of thepedal bar54. As such, the weight of thepedal bar54 can be used to bias the orientation of the pedal bar toward a position corresponding toward the closed position of thelid26. Optionally, other biasing devices can be used to bias thelid26 toward the closed position.
• Thepedal bar54 can be made from any material. Preferably, the pedal bar is made from a relatively heavy metal, so as to provide some ballast to thereceptacle10 and/or as noted above, a biasing effect for biasing thelid26 toward the closed position. However, thepedal bar54 can be made from any material, including light-weight material, such as plastic, aluminum, or heavier material such as steel, or any other metal or plastic or wood. The front end of thepedal bar54 can be connected to thepedal member52 in any known manner. The rear end of thepedal bar54, on the other hand, can be connected to a dampeningmechanism60, described in greater detail below.
• With reference toFIGS. 4-6, the receptacle can include an upperperipheral lip60 configured to engage the inner peripheral lip42 (FIG. 2) of theframe18. In some embodiments, theliner14 can include a plurality of stiffeningribs62 configured to reinforce thelip60.
• In some embodiments, with reference toFIG. 5, a bottom64 of theliner14 can include a recessed area66 configured to engage a projection on the top of the dampening mechanism60 (FIG. 3). As such, the recessed portion66 can engage the projection and thereby rest in the position illustrated inFIG. 6, which can help a user adjust theliner14 and/or install a new trash bag into theliner14. Additionally, with reference toFIG. 5, theliner14 can include abag retention aperture70, theaperture70 can include a plurality ofdeflectable petals72, configured to engage a portion of a plastic bag pushed through theaperture70. As such, a plastic bag can be more securely retained on theliner14.
• With reference toFIGS. 7 and 8, as noted above, thebase16 can be configured to pivotally support thepedal assembly50. In the illustrated embodiment, thebase16 includes a raisedupper wall80 that can include an outerperipheral wall82 and a taperedinner wall84. Theouter wall82 can be configured to rest against theshell12. The inner taperedwall84 can be tapered so as to guide the lower end of the liner14 (FIG. 5) into a centered position as it is lowered into thereceptacle10. However, other configurations can also be used.
• As shown inFIG. 7, thebase16 can also include a damper mounting portion90 configured to receive the dampeningmechanism60. In the illustrated embodiment, the damper mounting portion90 includes aplatform92 which includes an aperture (not shown) through which a portion of the dampeningmechanism60 extends. A lower end of the dampening mechanism can be connected to the rear end of thepedal bar54.
• With reference toFIG. 8, thebase16 can include a plurality ofwalls94,96 defining a channel in which thepedal bar54 can be disposed. Optionally, thebase16 can include a plurality ofadditional stiffening ribs98 extending in a generally radial direction away from thewalls94,96, to the outer periphery of the base16 to provide further stiffening of thebase16. However, other configurations can also be used.
• The base16 can also include one or a plurality oflegs100 configured to support the base16 on a flat surface, such as a floor. However, other configurations can also be used. In some embodiments, thebase16 can include aperipheral skirt portion102 disposed below the outerperipheral wall82 so as to provide a clean aesthetically pleasing outer appearance. As noted above, thefulcrum rod56 can be supported by the base16 to allow thepedal bar54 to pivot thereabout.
• With reference toFIG. 9, as noted above, a rear end of thepedal bar54 can be connected to a dampeningmechanism60. In some embodiments, the rear end of thepedal bar54 includes a pivot rod110 that connects to an aperture disposed in the lower portion of the dampeningmechanism60. In the position illustrated inFIG. 9, thepedal bar54 is pressed downwardly at the end on which thepedal member52 is mounted, thereby pressing the rear end of thepedal bar54 upwardly, which in turn, pushes the liftingrod36 upwardly opening thelid26.
• FIG. 10 illustrates an optional design for alower portion112 of the dampeningmechanism60. As shown inFIG. 10, thelower portion112 of the dampeningmechanism60 can include first andsecond apertures114,116 that are skewed relative to one another. For example, theaperture114 can be configured to receive the pin110 (FIG. 9) mounted at the rear of thepedal bar54. On the other hand, theaperture116 can be configured to receive a lower end of the liftingrod36. These twoapertures114,116 are disposed at skewed angles relative to one another, described in greater detail below with reference toFIG. 13.
• As shown inFIG. 10, theaperture114 can have an O-void or oblong bore. For example, theaperture114 can include two centers ofradiuses120,122. As such the pin110 can slide transversely to the vertical direction ofFIG. 10. This allows thelower portion112 of the dampeningmechanism62 to follow a generally vertical path as it is pushed upwardly by the pin110. In other words, because thepedal bar54 pivots about thefulcrum rod56, the pin110 follows a generally arcuate path. Thus, when the pedal bar is moved from the closed position to the open position, the pin110 translates in a lateral direction relative to theaperture114, for example, between thecenters120,122, as thelower portion112 moves in a more purely vertical direction. Thus, the lower end of the liftingrod36 is also pushed in a more purely vertical direction.
• In some embodiments, thelower portion112 can includeadditional stiffening walls126,128 to provide additional stiffness for thelower portion112.
• With reference toFIGS. 11 and 12, thelower portion112 can define a lower end of a piston assembly140 of the dampeningmechanism60. For example, as shown inFIGS. 11 and 12, thelower portion112 can include, at its upper end, an air piston142, with thelower portion112 forming a piston rod for the piston142. The piston142 is disposed within ahousing144 having aninternal bore146. Thebore146 and the piston142 are sized such that the piston142 can move reciprocally within thebore146.
• For example, the piston142 can be sized to fit snuggly within thebore146. In some embodiments, the piston142 can be configured to provide relatively little resistance to the upward movement of the piston142, but provide greater resistance against the downward movement of the piston142. This can be accomplished in any known manner.
• For example, the piston142 can be formed from a pair of plate members having an outer diameter that is close to the inner diameter of thebore146. A lubricant can be disposed in thehousing144 so as to reduce the sliding friction between the outer edges of the piston plates142 and theinner bore146. In some embodiments, the piston142 can include check valves to allow air to pass through the piston142 during the upward movement of the piston142 but to generate resistance against the flow of air through the piston142 during the downward movement of the piston142.
• In some embodiments, this effect can be provided by alip seal148 which can be connected to an outer periphery of thepiston148 and can be configured to operate similarly to a check valve. Such a design is disclosed in U.S. patent application Ser. No. 11/475,349 filed Jun. 27, 2006 published as U.S. Patent Publication No. 2007/0012699A1 on Jan. 18, 2007, the contents of which is hereby expressly incorporated by reference. Additionally, the disclosure of the lip seal as incorporated into the housing of the damper, its manufacture and use are incorporated herein by reference. The lip seal from the U.S. 2007/0012699A1 publication can also be used as thelip seal148 ofFIG. 12 herein. Thus, a further description of thelip seal148 is not repeated herein.
• With reference toFIG. 13, as noted above, the respective axes of theapertures114,116, can be skewed relative to each other. To illustrate this relationship,FIG. 13 is a schematic top plan view of thelower portion112 and its location relative to theshell12, hinge28 andpedal bar54.
• As shown inFIG. 13, theaperture116 extends along anaxis150. Additionally, theaperture114, in the illustrated embodiment includes twoaxes120,122. As described above, the use of an oblong cross-section aperture provides clearance for the pin110 (FIG. 9) to slide laterally during operation of thepedal bar54.
• In some embodiments, the relative angles A between theaxis150 andaxes120,122 can be any angle, depending on the configuration of thereceptacle10. In some embodiments, the angle A can be about 45°.
• A 45° orientation can provide additional advantages. For example, also illustrated inFIG. 13, is thelongitudinal axis160 of thepedal bar54. Additionally, thehinge device28 connecting thelid26 to theframe18 is also illustrated along with itsaxis162. Finally, theshell12 is illustrated in phantom line as well as walls of a room that form a corner C.
• With thereceptacle10 placed such that theshell12 has its rear corner disposed adjacent to corner C of a room, which is formed by walls that extend in a generally 90° angle, theaxis162 of thehinge device28 extends generally parallel to one of the walls. Additionally,axis160 of thepedal bar54 extends generally directly toward the corner C, roughly at a 45° angle relative to the walls and theaxis162. In this orientation, although not illustrated inFIG. 13, the longitudinal axis of the pin110 extends through theaperture114 generally parallel to theaxes120,122.
• Additionally, the lower end of the liftingrod36 extends through theaperture116 generally parallel to theaxis150. Thus, during operation, the lower end of the liftingrod36 and the upper end of the liftingrod36 can pivot about axes that are parallel to theaxis150 andaxis162. Thus, thepedal bar54 and the pin110 pivot about axes that are parallel with each other and the lower and upper end of the liftingrod36 as well as thelid26 also pivot about axes that are parallel with each other, while thelower portion112 moves in a generally vertical direction. This provides a smooth operation as well as a secure fixation of the spacing between theapertures114,116.
• With theapertures114,116 disposed in thelower portion112, which is formed as a single component, these apertures are fixed relative to each other. In some embodiments, thelower portion112, including theapertures114,116, can be formed from a single monolithic piece of material, such as a plastic, metal or any other material. However, in other embodiments, the components of thelower portion112, including those components forming theapertures114,116, can be from separate components connected together.
• FIG. 14 illustrates a motion of the liftingrod36 during vertical movement of thelower portion112. For example, inFIG. 14, thelower portion112 is illustrated in solid line, in the lower position, i.e., the position corresponding to a closed position of thelid26. The open position of thelid26 is illustrated in phantom line, along with the corresponding orientation of the liftingrod36 and theaperture116.
• As noted above, the lower end of the liftingrod36 pivots about theaxis150 as thelower portion112 moves in a vertical direction. For example, as is apparent fromFIG. 14, the lifting rod pivots slightly in a counterclockwise direction when thelower portion112 is moved from the lower position to the upper position.
• Additionally, the upper end of the liftingrod36 pivots about anaxis170. Thus, during movement from the lower portion from the lower position to the upper position, the upper end of the liftingrod36 also pivots in a clockwise direction about theaxis170. These pivoting motions, about theaxes150,170 are both parallel to theaxis162 of thehinge device128.
• Although these inventions have been disclosed in the context of certain preferred embodiments and examples, it will be understood by those skilled in the art that the present inventions extend beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the inventions and obvious modifications and equivalents thereof. In addition, while several variations of the inventions have been shown and described in detail, other modifications, which are within the scope of these inventions, will be readily apparent to those of skill in the art based upon this disclosure.
