Abstract
The present invention is a closable trash can having an inner liner, removable cover and a pedal assembly. The cover includes a recessible lid. A riser attached to the pedal assembly acts on an actuator to rotate the recessible lid to reveal an opening defined by the removable cover. A biasing spring rotates the recessible cover closed when pressure is released from the pedal assembly.
Description
CA Application Agent's Ref: 68849/00113 STEP TRASH CAN
4 [0001] The present invention broadly pertains to trash receptacles, particularly to covered trash receptacles, and more particularly to trash can covers with movable lids.
8 [0002] Trash cans are often required to be convenient, decorative, and easy to clean as 9 well as to store trash. Trash cans would be more convenient if a user were able to easily deposit trash into a container. For open containers, depositing trash is uncomplicated ¨ trash is 11 merely dropped into an open container. However, open trash containers are usually unsightly 12 and often unsanitary. More desirable would be a trash can that included a cover and still 13 enabled easy trash deposit.
14 [0003] Covered trash cans are generally more decorative than open containers but are not as convenient. If the cover has an opening, in order to preserve the advantages of a cover, 16 the opening must be closed However, to open the closure to deposit trash, it usually must be 17 touched, either by using a user's hand or a part of the trash being held by the user. A typical 18 example is seen with hinged lids that cover the opening in the cover or are directly attached to 19 the can itself. Pushing the hinged closure open involves touching a surface that is usually dirty, sticky with spilled liquids and trash and often unsanitary. Other types of covers may include a 21 lid that can be opened without touching but must be pushed closed due to failure of the closure 22 system or because friction from dirt or rusted components prevents the lid from falling freely to a 23 closed position.
24 [0004] In addition, the components of mechanically operated closures often become fouled and dirty because they are positioned inside the trash can where they are exposed to the 26 trash being deposited into the container. These components are difficult to clean and, because 27 they are out of sight, they will often never be cleaned. This difficulty is enhanced with parts that 28 are small and thus difficult to access for a thorough cleaning. If the parts are made of metal, 29 they will likely rust again fouling the mechanism eventually making automatic closure problematic.
31 [0005] Thus, there is a need in the field for a covered trash can with a closure 32 mechanism which a user does not have to touch with his hands and which closes in a reliable 33 manner.
22185491.1 1 CA Application Agent's Ref: 68849/00113 2 [0006] The present invention broadly comprises a trash can with recessible lid 3 comprising an outer shell having a bottom surface; at least one outer wall extending from the 4 bottom surface to at least one upper edge with opposing grooves formed in the at least one upper edge and a depression formed in the at least one wall. The trash can also includes an 6 inner liner having a bottom surface and at least one liner wall extending from the bottom surface 7 to at least one liner wall upper edge. There is a wall groove formed extending from the bottom 8 surface of the inner liner to an upper edge of the at least one liner wall, so that the wall groove is 9 opposite the depression. The inner liner is configured to nest within the outer shell. A cover is shaped to fit over the outer shell with an opening defined by the cover; a recessible lid sized to 11 cover/close the opening, with the recessible lid rotatably attached to an inner surface of the 12 cover. The cover includes an actuator rotatably attached to the recessible lid and also rotatably 13 attached to the inner surface of the cover and a biasing spring operatively attached to the 14 recessible lid. The trash can also includes a pedal assembly, the pedal assembly including a pedal lever operatively attached to the outer shell having a first end and a second end, the first 16 end having a pedal and the second end functionally attached to a riser, wherein the riser is 17 between the wall groove and the outer wall and movably attached to the actuator.
18 [0007] One object of the invention is to provide a trash can that reliably closes without 19 the cover being touched by the user by the user.
[0008] A second object of the invention is to supply a trash can that is easily cleaned.
21 [0009] A third object of the invention is to present a novel trash can with simple 22 mechanical parts.
23 [0010] A further object of the invention is to supply a trash can in which the components 24 of the actuating mechanism are outside the trash storage area.
27 [0011] The nature and mode of the operation of the present invention will now be more 28 fully described in the following detailed description of the invention taken with the accompanying 29 drawing Figures, in which:

Although any methods, devices or 31 materials similar or equivalent to those described herein can be used in the practice or testing of 32 the invention, the preferred methods, devices, and materials are now described. It should be 33 appreciated that the term "proximate" is synonymous with terms such as "nearby", "close", 22185491.1 3 CA Application Agent's Ref: 68849/00113 1 "adjacent", "neighboring", "immediate", "adjoining", etc., and such terms may be used 2 interchangeably as appearing in the specification and claims.
3 [0024] Unless defined otherwise, all technical and scientific terms used herein have the 4 same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices or materials similar or equivalent to those described 6 herein can be used in the practice or testing of the invention, the preferred methods, devices, 7 and materials are now described.
8 [0025] Adverting to the drawings, Figure 1 is a top perspective view of trash can 10.
9 Outer shell 12 has at least one outer wall 14 which supports cover 20 which is releasably attached using a friction fit as described below. It will be recognized by persons having skill in 11 the art that other methods of releasable attachment may be used, including but not limited to, 12 clamps, pins, nut and bolt assemblies, etc. A friction fit is a preferred embodiment as it does not 13 require additional parts. Outer shell 12 may have many shapes having more than one wall such 14 as squares, octagons, or other polygonal shapes. Preferably, pedal 42a is positioned in wall depression 16 ("depression 16") to allow it to remain close to outer shell 12 and still be easy to 16 access with the user's foot.
17 [0026] Cover 20 includes recessible lid 22. Lip 22a on closure 22 ensures the opening 18 21, not seen in Figure 1, is closed. By recessible is meant that lid 22 moves back underneath 19 cover 20 to reveal opening 21 which is defined by cover 20.
[0027] Figure 2 is an exploded top perspective view of trash can 10. Pedal assembly 40 21 includes pedal lever 42 which has two ends. At one end is pedal 42a, which in the embodiment 22 shown is integral with pedal lever 42. By integral is meant that the component parts are formed 23 together as a single unit. Persons of skill in the art will recognize that pedal 42a may be 24 attached to pedal lever 42 by screws, rivets, adhesives or other suitable attachment means.
[0028] Riser 44 has an attachment end 46 which is movably attached to second end 26 46a of pedal lever 42. By movably attached is meant that while riser 44 and pedal lever 42 are 27 fastened together, riser 44 and pedal lever 42 may independently rotate around and/or slide 28 laterally at the connection point. One such movable connection may be a hinged connection 29 with room for attachment end 46 to slide laterally on rod 47 of end 46a with rod 47 longer than the width of attachment end 46.
31 [0029] Figure 2 depicts upper edge 19 of outer shell 12 with opposing grooves 19a. As 32 described below, grooves 19a receive ears 20a which are integral with cover 20. Also seen is 33 channel 18 formed in the bottom surface of outer shell 12. In the embodiment shown, when 34 trash can 10 is assembled, pedal assembly 40 fits into and is operatively attached to the walls of 22185491.1 4 CA Application Agent's Ref: 68849/00113 1 channel 18. By operatively attached is meant that a component or device is connected either 2 directly or indirectly to a second component and causes one of those components to function.
3 For example, as described above, pedal lever 42 is described as operatively attached or 4 operationally attached to the walls of channel 18 meaning the attachment is such as to allow pedal lever 42 to operate to move riser up and down as described below.
6 [0030] Inner liner 30 includes a bottom surface and at least one liner wall 32 and is 7 shaped to nest within outer shell 12. By nest is meant to fit compactly together or within one 8 another. Therefore, liner depression 36 will nest against shell depression 16. Wall groove 38 9 ("groove 38") is opposite liner depression 36 and is formed from liner wall 32. When trash can 10 is assembled, riser 44 from pedal assembly will extend between the inner surface of shell 11 wall 14 and groove 38.
12 [0031] Cover 20 defines opening 21 which is covered or closed by lid 22. Lid ears 22b 13 are attached to or integral with lid 22 and included pins 22c and holes 22d. Actuator 26 is 14 rotatably attached to the inside of cover 20 with pins 28 inserted into receiving holes 24.
Receiver 29 is contacted on its bottom surface by the top of riser 44.
16 [0032] Lid 22 is rotatably attached to cover 20 with lid receiving hole 22d receiving pin 17 25 attached to or integral with the inner surface of cover 20. Not shown in Figure 2 is ear pin 18 22c inserted into hole 27 on actuator 26.
19 [0033] Figures 3-5 are top perspective views depicting the sequence in which the components of trash can 10 are assembled to form the complete unit. In Figure 3, liner 30 is 21 placed in a nesting manner within outer shell 12. Groove 19a is open to receive ears 20a on 22 cover 20. Riser 44 is shown between groove 38 and outer shell wall 14.
Figure 4 shows 23 actuator 26 attached to the inside of cover 20 by inserting pins 28 into receiving holes 24.
24 Figure 5 shows cover 20 releasably attached to outer shell 12 by the friction fit of ears 20a into grooves 19a.
26 [0034] Figure 6 is a rear perspective view of trash can 10 with the rear portion of outer 27 wall 14 partially cut away to show the operative relationship of riser 44 with receiver 29 of 28 actuator 26. Also removed is the top of cover 20 exposing actuator 26 and lid 22 attached to 29 the bottom periphery of cover 20.
[0035] Figure 6A is an enlarged top view of circled area 6A in Figure 6.
Actuator 26 is 31 rotatably attached to cover 20 by pin 25 which extends through hole 22d on ear 22b of lid 22.
32 Spring 50 is wrapped around pin 25. One end of spring 50 is anchored to anchor 50a formed 33 from or attached to the inside surface of cover 20. The second end of spring 50 is attached to 22185491.1 5 CA Application Agent's Ref: 68849/00113 1 the lower portion of pin 22c which extends from lid ear 22b through hole 27 of actuator 26. This 2 assembly forms the rotatable attachment of lid 22 to both cover 20 and actuator 26.
3 [0036] Figure 7 is a cross section of trash can 10 in the closed position. Inner liner 30 is 4 supported by channel 18 formed from the bottom surface of outer shell 12.
Slot 18a is formed in both walls of channel 18 and receives pegs 48 (not seen in Figure 7) that extend from pedal 6 lever 42. In the closed position, pedal 42a is up and the opposing second end 46a is down. For 7 this reason, riser 44 is also at the bottom of its travel path between groove 38 and outer shell 8 wall 14. Actuator 26 is attached to both cover 20 by pin 28 and to lid 22 by pin 22c extending 9 through hole 27. Lid 22 is also attached to cover 20 by pin 25 inserted through hole 22d.
[0037] Figure 8 is a cross section of trash can 10 as it is being opened.
Downward 11 pressure on pedal 42a lifts riser 44. Riser 44 contacts receiver 29 lifting receiver 29. Actuator 12 26 then pivots on pins 28 and 22c forcing the two ends of actuator 26 down. This downward 13 action on pin 22c forces lid 22 to rotate up exposing opening 21. Figure 9 is a cross section 14 view showing lid 22 opened to its full extent.
[0038] When pressure is released on pedal 42a, riser 44 falls relieving the upward force 16 on receiver 29. At the same time, spring 50, which has been biased or stretched, moves to its 17 resting position forcing pin 22c to rotate upward which acts to force lid 22 to move down to the 18 closed position. The use of spring 50 to close lid 22 provides the advantage a positive 19 mechanical force to help close lid 22 in addition to the effect of the dropping of riser 44. This helps to overcome any friction or other problems that would keep lid 22 open even after riser 44 21 drops enabling lid 22 to close without help from the user.
22 [0039] Thus it is seen that the objects of the invention are efficiently obtained, although 23 changes and modifications to the invention should be readily apparent to those having ordinary 24 skill in the art, which changes would not depart from the spirit and scope of the invention as claimed.

8 [0025] Adverting to the drawings, Figure 1 is a top perspective view of trash can 10.
9 Outer shell 12 has at least one outer wall 14 which supports cover 20 which is releasably attached using a friction fit as described below. It will be recognized by persons having skill in 11 the art that other methods of releasable attachment may be used, including but not limited to, 12 clamps, pins, nut and bolt assemblies, etc. A friction fit is a preferred embodiment as it does not 13 require additional parts. Outer shell 12 may have many shapes having more than one wall such 14 as squares, octagons, or other polygonal shapes. Preferably, pedal 42a is positioned in wall depression 16 ("depression 16") to allow it to remain close to outer shell 12 and still be easy to 16 access with the user's foot.
17 [0026] Cover 20 includes recessible lid 22. Lip 22a on closure 22 ensures the opening 18 21, not seen in Figure 1, is closed. By recessible is meant that lid 22 moves back underneath 19 cover 20 to reveal opening 21 which is defined by cover 20.
[0027] Figure 2 is an exploded top perspective view of trash can 10. Pedal assembly 40 21 includes pedal lever 42 which has two ends. At one end is pedal 42a, which in the embodiment 22 shown is integral with pedal lever 42. By integral is meant that the component parts are formed 23 together as a single unit. Persons of skill in the art will recognize that pedal 42a may be 24 attached to pedal lever 42 by screws, rivets, adhesives or other suitable attachment means.
[0028] Riser 44 has an attachment end 46 which is movably attached to second end 26 46a of pedal lever 42. By movably attached is meant that while riser 44 and pedal lever 42 are 27 fastened together, riser 44 and pedal lever 42 may independently rotate around and/or slide 28 laterally at the connection point. One such movable connection may be a hinged connection 29 with room for attachment end 46 to slide laterally on rod 47 of end 46a with rod 47 longer than the width of attachment end 46.
31 [0029] Figure 2 depicts upper edge 19 of outer shell 12 with opposing grooves 19a. As 32 described below, grooves 19a receive ears 20a which are integral with cover 20. Also seen is 33 channel 18 formed in the bottom surface of outer shell 12. In the embodiment shown, when 34 trash can 10 is assembled, pedal assembly 40 fits into and is operatively attached to the walls of 22185491.1 4 CA Application Agent's Ref: 68849/00113 1 channel 18. By operatively attached is meant that a component or device is connected either 2 directly or indirectly to a second component and causes one of those components to function.
3 For example, as described above, pedal lever 42 is described as operatively attached or 4 operationally attached to the walls of channel 18 meaning the attachment is such as to allow pedal lever 42 to operate to move riser up and down as described below.
6 [0030] Inner liner 30 includes a bottom surface and at least one liner wall 32 and is 7 shaped to nest within outer shell 12. By nest is meant to fit compactly together or within one 8 another. Therefore, liner depression 36 will nest against shell depression 16. Wall groove 38 9 ("groove 38") is opposite liner depression 36 and is formed from liner wall 32. When trash can 10 is assembled, riser 44 from pedal assembly will extend between the inner surface of shell 11 wall 14 and groove 38.
12 [0031] Cover 20 defines opening 21 which is covered or closed by lid 22. Lid ears 22b 13 are attached to or integral with lid 22 and included pins 22c and holes 22d. Actuator 26 is 14 rotatably attached to the inside of cover 20 with pins 28 inserted into receiving holes 24.
Receiver 29 is contacted on its bottom surface by the top of riser 44.
16 [0032] Lid 22 is rotatably attached to cover 20 with lid receiving hole 22d receiving pin 17 25 attached to or integral with the inner surface of cover 20. Not shown in Figure 2 is ear pin 18 22c inserted into hole 27 on actuator 26.

Also removed is the top of cover 20 exposing actuator 26 and lid 22 attached to 29 the bottom periphery of cover 20.
[0035] Figure 6A is an enlarged top view of circled area 6A in Figure 6.
Actuator 26 is 31 rotatably attached to cover 20 by pin 25 which extends through hole 22d on ear 22b of lid 22.
32 Spring 50 is wrapped around pin 25. One end of spring 50 is anchored to anchor 50a formed 33 from or attached to the inside surface of cover 20. The second end of spring 50 is attached to 22185491.1 5 CA Application Agent's Ref: 68849/00113 1 the lower portion of pin 22c which extends from lid ear 22b through hole 27 of actuator 26. This 2 assembly forms the rotatable attachment of lid 22 to both cover 20 and actuator 26.
3 [0036] Figure 7 is a cross section of trash can 10 in the closed position. Inner liner 30 is 4 supported by channel 18 formed from the bottom surface of outer shell 12.
Slot 18a is formed in both walls of channel 18 and receives pegs 48 (not seen in Figure 7) that extend from pedal 6 lever 42. In the closed position, pedal 42a is up and the opposing second end 46a is down. For 7 this reason, riser 44 is also at the bottom of its travel path between groove 38 and outer shell 8 wall 14. Actuator 26 is attached to both cover 20 by pin 28 and to lid 22 by pin 22c extending 9 through hole 27. Lid 22 is also attached to cover 20 by pin 25 inserted through hole 22d.
[0037] Figure 8 is a cross section of trash can 10 as it is being opened.
Downward 11 pressure on pedal 42a lifts riser 44. Riser 44 contacts receiver 29 lifting receiver 29. Actuator 12 26 then pivots on pins 28 and 22c forcing the two ends of actuator 26 down. This downward 13 action on pin 22c forces lid 22 to rotate up exposing opening 21. Figure 9 is a cross section 14 view showing lid 22 opened to its full extent.
[0038] When pressure is released on pedal 42a, riser 44 falls relieving the upward force 16 on receiver 29. At the same time, spring 50, which has been biased or stretched, moves to its 17 resting position forcing pin 22c to rotate upward which acts to force lid 22 to move down to the 18 closed position. The use of spring 50 to close lid 22 provides the advantage a positive 19 mechanical force to help close lid 22 in addition to the effect of the dropping of riser 44. This helps to overcome any friction or other problems that would keep lid 22 open even after riser 44 21 drops enabling lid 22 to close without help from the user.
22 [0039] Thus it is seen that the objects of the invention are efficiently obtained, although 23 changes and modifications to the invention should be readily apparent to those having ordinary 24 skill in the art, which changes would not depart from the spirit and scope of the invention as claimed.
