Description
DIVIDED CART WITH U1~1ITARY DUAL-LID FRAME
BACKGROUND OF THE INVENTION
Field of the Invention The invention relates to waste collection containers. In one of its aspects, the invention relates to multiple-compartment waste collection containers that have lids in registry with each of the container compartments. In another of its aspects, the invention relates to container covers for multiple-compartment waste collection containers with independently and tandem operable individual lids for each of the container compartments.
Related Art The proper disposal and minimization of consumer waste has become of increasing concern. While a certain amount of consumer waste is relatively unsalvageable, the overwhelming majority of consumer waste can be recycled.
The first step in the recycling process is the separation of materials from a common waste stream, i.e. creating separate or segregated waste streams, each containing one class of material such as glass, plastic, paper, or metal. This separation can be accomplished by a waste disposal facility, but this has been found to be time-consuming and expensive. The most efficient level to accomplish this separation of waste material is at the generator level. The challenge has been to simplify the segregation process for the party generating the waste, and follow that with an efficient method of transferring the segregated waste to a disposal facility.
One manner in which this process has been addressed is by providing to the waste generator a divided container that is adapted to transfer segregated waste to a specialized waste collection vehicle operated by a waste collector.
These prior divided containers have taken the form of a common single-lid container to which an internal divider has been added; a container having a divider to which is attached a lid for each compartment within the container;
and a container having multiple compartments with individual lids attached to a common cover. Examples of these containers are disclosed in U.S. Patent No. 5,303,841 to Mezey, U.S. Patent No. 5,879,015 to Ramsey et al., and U.S. Patent No.
5,244,218 to Irwin. Other divided containers with various lid configurations, such as disclosed in U.S. Patent No. 5,072,852 to Smith et al., are not adapted to be used with a complementary waste collection vehicle.
SUMMARY OF THE INVENTION
S The invention relates to a divided cart for the separation of waste into independent waste streams, such as for the separation of recyclable materials from common rubbish or the separation of different types of recyclable material.
The divided cart has a plurality of interior compartments that are separated from each other by an interior dividing wall in the container. The container further has a cover and a plurality of lids which are in register with each compartment so that a user can gain access to a single compartment.
Each lid is mounted on a unitary frame that covers the entirety of the container. The lids are carried by the frame and are pivotally mounted to the frame and container about a common pivot axis that also pivotally mounts the frame to the 1 S container. A user can access all of the interior compartments simultaneously by pivoting the frame about the pivot axis to expose the interior of the container. The frame has a handle for the user to grasp to open the frame or by which a vehicle-mounted mechanism can open the frame while emptying the container into a waste collection vehicle adapted to receive the separated waste. The cover is mounted to the container so that it can be pivoted through an angle of about 270 degrees from a position overlying the compartments to a position substantially adjacent an upstanding side wall of the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refernng first to FIG. 1, a divided cart with unitary dual-lid frame comprises a cart 20 and a unitary dual-lid frame 60, the cart 20 and frame 60 being pivotally connected by a hinge pin 110.
The cart 20 comprises an upright perimeter wall 21 that defines a cart interior 30. The perimeter wall 21 comprises three vertically oriented portions. An upper perimeter wall portion 25 and a lower perimeter wall portion 26 are vertically separated by a shoulder 27. The shoulder 27 defines the transition between the upper portion 25 and the lower portion 26, the lower portion 26 having a smaller cross section than the upper portion 25.
The upper portion 25 of the perimeter wall 21 is generally rectangular in plan view, having rounded corners, while the lower portion 26 is more generally rounded in plan view. The upper portion 25 comprises two sidewalk 22, a front wall 23, and a rear wall 24 shown in FIG. 2.
The cart interior 30 is divided into two compartments 32, 34 of generally equal size by a divider wall 36. The divider wall 36 extends substantially the full height of the cart interior 30, and intersects and is generally perpendicular to the front and rear walls 23, 24 of the cart 20. The compartments need not be of equal size and can be of a variety of relative sizes, depending on the relative proportions of waste collected in any give community.
The cart 20 further comprises four cart hinge stand-off flanges 42, 44, 46, 48 that are attached to and project outwardly from the upper portion 25 of the rear wall 24 adjacent a top edge 28 of the perimeter wall 21. The flanges 42, 44, 46, 48 are each planar and generally identical in their oblong shape and further comprise a hinge pin aperture 49 passing therethrough adjacent one end of each flange 42, 44, 46, 48.
The plane of each flange 42, 44, 46, 48 is oriented vertically so that the flanges 42, 44, 46, 48 are parallel to each other and perpendicular to the rear wall 24 in one sense, but the oblong dimension of the flanges 42, 44, 46, 48 projects generally upwardly from the upper portion 25 with respect to a horizontal plane so that the end of each flange 42, 44, 46, 48 carrying the hinge pin aperture 49 is elevated above the top of the perimeter wall 21 and the hinge pin apertures 49 of the flanges 42, 44, 46, 48 are aligned, defining a hinge axis 112 transverse to the plane of the divider wall 36, and slightly elevated above the top of the perimeter wall 21.
The divided cart with unitary dual-lid frame further comprises a frame 60, the frame 60 being generally rectangular in plan view to correspond to the plan view of the upper portion 25 of the perimeter wall 21. The frame 60 has a perimeter generally defined by an annular frame skirt 62. As best illustrated in FIGS. 2 and 3, four generally oblong and planar frame hinge legs 72, 74, 76, 78 project outwardly and perpendicularly away from a rear side 64 of the frame skirt 62, the rear side 64 of the skirt 62 corresponding to the rear wall 24 of the upper portion 25. The planes defined by the legs 72, 74, 76, 78 lie generally adjacent and parallel to but slightly offset from the cart hinge stand-off flanges 42, 44, 46, 48. Each of the frame hinge legs 72, 74, 76, 78 has a hinge pin aperture 79 configured to align with the apertures 49. The apertures 79 of the two innermost frame hinge legs 74, 76 are connected by a hollow cylindrical hinge pin sleeve 114 longitudinally aligned with the hinge pin axis 112. Due to this connection, the legs 74, 76 must necessarily lie between the two innermost cart hinge stand-off flanges 44, 46.
Referring to FIG. 4, the perimeter wall 21 of the cart 20 terminates at its uppermost edge 28 in an outwardly projecting overhang 52 having a horizontal extension 54 perpendicular to the perimeter wall 21 and a vertical extension depending from the horizontal extension 54 and parallel to the upper portion 25 of the perimeter wall 21. An upstanding lip 58 extends upwardly from the innermost edge of the horizontal extension 54, defining the uppermost edge of the cart interior 30.
The frame skirt 62 is dimensioned to set flushly on the horizontal extension 54 closely outside the upstanding lip 58. Attached to and projecting from a -$-side of the frame skirt 62, the frame 60 further comprises a frame handle 66, which comprises an outwardly projecting plate 67 which lies in a substantially horizontal plane when the frame 60 is resting on top of the cart 20. The frame handle 66 further comprises a tab 68 attached to an end of the plate 67 opposite the frame skirt 62 and depending perpendicularly downwardly therefrom, substantially parallel to the side wall 22 of the cart 20.
The central portion 80 of the frame 60, interior to the frame skirt 62, is generally open. The central portion 80 is divided by a frame divider 81, forming two frame openings 82, 84. The frame divider 81 is arranged to align with the divider wall 36 of the cart interior 30, the resulting frame openings 82, 84 thereby aligning with the respective compartments 32, 34 of the cart interior 30. With reference to FIGS. 4 and 5, the perimeter of each frame opening 82, 84 is formed by an upturned lip 88.
The frame divider 81, having an upturned lip 88 adjacent to each of the frame openings 82, 84, forms an upwardly facing channel 86.
The frame 60 additionally comprises a pair of lids 92, 94 each generally rectangular in plan, and adapted to cover one of the frame openings 82, 84 in the frame 60. Each lid 92, 94 comprises a generally flat top portion 96 and a depending generally annular lid skirt 98. As best seen in FIGS. 4-6, the lid skirt 98 is adapted to fit closely about the upturned lip 88 surrounding each of the frame openings 82, 84 and within the channel 86 on the frame divider 81. Each top portion 96 generally extends outwardly a minimal distance from the skirt 98, except at a front handle portion 100 of the lids overlying the front wall 23 of the cart 20, the front handle portion 100 extending a sufficient distance beyond the skirt 98 for a user to readily grasp.
A pair of lid hinge legs 104 extends horizontally and perpendicularly from an enlarged rear portion 102 of the frame skirt 98 of each lid 92, 94.
The lid hinge legs 104 are aligned to be generally offset from, but adjacent to the frame hinge legs 72, 74, 76, 78. Each of the lid hinge legs 104 further comprises an aperture 109 configured to generally align with the apertures 79 in the frame hinge legs 72, 74, 76, 78 and the apertures 49 in the cart hinge stand-off flanges 42, 44, 46, 48.
FIG. 4 is a cross-sectional view taken through line 4-4 of FIG. 3;
FIG. 5 is a cross-sectional view taken through line 5-5 of FIG. 3; and FIG. 6 is a cross-sectional view taken through line 6-6 of FIG. 3.

Refernng first to FIG. 1, a divided cart with unitary dual-lid frame comprises a cart 20 and a unitary dual-lid frame 60, the cart 20 and frame 60 being pivotally connected by a hinge pin 110.
The cart 20 comprises an upright perimeter wall 21 that defines a cart interior 30. The perimeter wall 21 comprises three vertically oriented portions. An upper perimeter wall portion 25 and a lower perimeter wall portion 26 are vertically separated by a shoulder 27. The shoulder 27 defines the transition between the upper portion 25 and the lower portion 26, the lower portion 26 having a smaller cross section than the upper portion 25.
The upper portion 25 of the perimeter wall 21 is generally rectangular in plan view, having rounded corners, while the lower portion 26 is more generally rounded in plan view. The upper portion 25 comprises two sidewalk 22, a front wall 23, and a rear wall 24 shown in FIG. 2.
The cart interior 30 is divided into two compartments 32, 34 of generally equal size by a divider wall 36. The divider wall 36 extends substantially the full height of the cart interior 30, and intersects and is generally perpendicular to the front and rear walls 23, 24 of the cart 20. The compartments need not be of equal size and can be of a variety of relative sizes, depending on the relative proportions of waste collected in any give community.
The cart 20 further comprises four cart hinge stand-off flanges 42, 44, 46, 48 that are attached to and project outwardly from the upper portion 25 of the rear wall 24 adjacent a top edge 28 of the perimeter wall 21. The flanges 42, 44, 46, 48 are each planar and generally identical in their oblong shape and further comprise a hinge pin aperture 49 passing therethrough adjacent one end of each flange 42, 44, 46, 48.
The plane of each flange 42, 44, 46, 48 is oriented vertically so that the flanges 42, 44, 46, 48 are parallel to each other and perpendicular to the rear wall 24 in one sense, but the oblong dimension of the flanges 42, 44, 46, 48 projects generally upwardly from the upper portion 25 with respect to a horizontal plane so that the end of each flange 42, 44, 46, 48 carrying the hinge pin aperture 49 is elevated above the top of the perimeter wall 21 and the hinge pin apertures 49 of the flanges 42, 44, 46, 48 are aligned, defining a hinge axis 112 transverse to the plane of the divider wall 36, and slightly elevated above the top of the perimeter wall 21.
The divided cart with unitary dual-lid frame further comprises a frame 60, the frame 60 being generally rectangular in plan view to correspond to the plan view of the upper portion 25 of the perimeter wall 21. The frame 60 has a perimeter generally defined by an annular frame skirt 62. As best illustrated in FIGS. 2 and 3, four generally oblong and planar frame hinge legs 72, 74, 76, 78 project outwardly and perpendicularly away from a rear side 64 of the frame skirt 62, the rear side 64 of the skirt 62 corresponding to the rear wall 24 of the upper portion 25. The planes defined by the legs 72, 74, 76, 78 lie generally adjacent and parallel to but slightly offset from the cart hinge stand-off flanges 42, 44, 46, 48. Each of the frame hinge legs 72, 74, 76, 78 has a hinge pin aperture 79 configured to align with the apertures 49. The apertures 79 of the two innermost frame hinge legs 74, 76 are connected by a hollow cylindrical hinge pin sleeve 114 longitudinally aligned with the hinge pin axis 112. Due to this connection, the legs 74, 76 must necessarily lie between the two innermost cart hinge stand-off flanges 44, 46.
Referring to FIG. 4, the perimeter wall 21 of the cart 20 terminates at its uppermost edge 28 in an outwardly projecting overhang 52 having a horizontal extension 54 perpendicular to the perimeter wall 21 and a vertical extension depending from the horizontal extension 54 and parallel to the upper portion 25 of the perimeter wall 21. An upstanding lip 58 extends upwardly from the innermost edge of the horizontal extension 54, defining the uppermost edge of the cart interior 30.
The frame skirt 62 is dimensioned to set flushly on the horizontal extension 54 closely outside the upstanding lip 58. Attached to and projecting from a -$-side of the frame skirt 62, the frame 60 further comprises a frame handle 66, which comprises an outwardly projecting plate 67 which lies in a substantially horizontal plane when the frame 60 is resting on top of the cart 20. The frame handle 66 further comprises a tab 68 attached to an end of the plate 67 opposite the frame skirt 62 and depending perpendicularly downwardly therefrom, substantially parallel to the side wall 22 of the cart 20.
The central portion 80 of the frame 60, interior to the frame skirt 62, is generally open. The central portion 80 is divided by a frame divider 81, forming two frame openings 82, 84. The frame divider 81 is arranged to align with the divider wall 36 of the cart interior 30, the resulting frame openings 82, 84 thereby aligning with the respective compartments 32, 34 of the cart interior 30. With reference to FIGS. 4 and 5, the perimeter of each frame opening 82, 84 is formed by an upturned lip 88.
The frame divider 81, having an upturned lip 88 adjacent to each of the frame openings 82, 84, forms an upwardly facing channel 86.
The frame 60 additionally comprises a pair of lids 92, 94 each generally rectangular in plan, and adapted to cover one of the frame openings 82, 84 in the frame 60. Each lid 92, 94 comprises a generally flat top portion 96 and a depending generally annular lid skirt 98. As best seen in FIGS. 4-6, the lid skirt 98 is adapted to fit closely about the upturned lip 88 surrounding each of the frame openings 82, 84 and within the channel 86 on the frame divider 81. Each top portion 96 generally extends outwardly a minimal distance from the skirt 98, except at a front handle portion 100 of the lids overlying the front wall 23 of the cart 20, the front handle portion 100 extending a sufficient distance beyond the skirt 98 for a user to readily grasp.
A pair of lid hinge legs 104 extends horizontally and perpendicularly from an enlarged rear portion 102 of the frame skirt 98 of each lid 92, 94.
The lid hinge legs 104 are aligned to be generally offset from, but adjacent to the frame hinge legs 72, 74, 76, 78. Each of the lid hinge legs 104 further comprises an aperture 109 configured to generally align with the apertures 79 in the frame hinge legs 72, 74, 76, 78 and the apertures 49 in the cart hinge stand-off flanges 42, 44, 46, 48.
The hinge pin 110 is adapted to be inserted through the apertures 49, 79, 109 formed in the cart hinge stand-off flanges 42, 44, 46, 48, frame hinge legs 72, 74, 76, 78, and lid hinge legs 104, respectively, and the hinge pin sleeve 114, and aligned with the hinge pin axis 112 defined by the apertures 49, 79, 109. A
second hinge pin sleeve 116 is interposed between the stand-off flanges 42, 44, and a third hinge pin sleeve 118 is interposed between the stand-off flanges 46, 48, each of the sleeves being a hollow cylinder longitudinally aligned about the hinge pin axis 112.
The hinge pin is inserted through the apertures 49, 79, 109 and the hinge pin sleeves 114, 116, 118, the hinge pin sleeves 114, 116, 118 effectively covering the length of the hinge pin 110. The frame 60 and lids 92, 94 are thus independently pivotable about the hinge pin axis 112 with respect to the cart 20, and can be rotated from a closed position aligned with the top of the cart 20 to an open position wherein the frame 60 and lids 92, 94 are hanging from the hinge pin 110 parallel and adjacent to the rear wall 24 of the cart 20.
The hinge pin sleeves 114, 116, 118 can also serve as a handle for the divided cart with unitary dual-lid frame.
OPERATION
Each compartment 32, 34 of the divided cart with unitary dual-lid frame can be designated to accept a certain type of waste. A user depositing waste in the respective compartment 32, 34 need only open the appropriate lid 92, 94 over the desired compartment 32, 34 depending upon the waste being deposited. Each of the respective lids 92, 94 is independently pivotable about the hinge pin 110 that connects the lids 92, 94, frame 60, and cart 20.
The divided cart with unitary dual-lid frame is intended to be emptied in one motion by a vehicle (not shown) adapted to receive the waste from the divided cart. The divided cart can be grasped by a pincer mechanism, as is well known in the art, the pincers grasping the lower portion 26 of the perimeter wall 21 and taking advantage of the shoulder 27 to expedite lifting of the divided cart. The mechanism will further have an arm, hook, rail or other structure provided so that as the divided cart is inverted over a waste receiving area of the vehicle, the frame handle 66 is engaged so as to rotate the frame 60 about the hinge pin 110, simultaneously lifting both lids 92, 94 and thereby exposing both compartments 32, 34 of the cart 20.
The receiving area of the vehicle will necessarily have a mechanism for diverting the contents of the compartment 32, 34 into separate receptacles within the vehicle.
It should be noted that while the preferred embodiment has been described as having two compartments 32, 34 within the cart 20 and a corresponding two lids 92, 94, the scope of this invention encompasses divided carts having three or more compartments with their associated lids and a divided cart having more than one frame with a quantity of associated lids. For example, a larger divided cart can have two frames associated with four or more lids. This might be required in instances where the receptacles on the vehicle are not adjacent one another, and it would be necessary to open groups of lids independently.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the foregoing description and drawings without departing from the spirit of the invention as defined in the appended claims.
second hinge pin sleeve 116 is interposed between the stand-off flanges 42, 44, and a third hinge pin sleeve 118 is interposed between the stand-off flanges 46, 48, each of the sleeves being a hollow cylinder longitudinally aligned about the hinge pin axis 112.
The hinge pin is inserted through the apertures 49, 79, 109 and the hinge pin sleeves 114, 116, 118, the hinge pin sleeves 114, 116, 118 effectively covering the length of the hinge pin 110. The frame 60 and lids 92, 94 are thus independently pivotable about the hinge pin axis 112 with respect to the cart 20, and can be rotated from a closed position aligned with the top of the cart 20 to an open position wherein the frame 60 and lids 92, 94 are hanging from the hinge pin 110 parallel and adjacent to the rear wall 24 of the cart 20.
The hinge pin sleeves 114, 116, 118 can also serve as a handle for the divided cart with unitary dual-lid frame.
OPERATION
Each compartment 32, 34 of the divided cart with unitary dual-lid frame can be designated to accept a certain type of waste. A user depositing waste in the respective compartment 32, 34 need only open the appropriate lid 92, 94 over the desired compartment 32, 34 depending upon the waste being deposited. Each of the respective lids 92, 94 is independently pivotable about the hinge pin 110 that connects the lids 92, 94, frame 60, and cart 20.
The divided cart with unitary dual-lid frame is intended to be emptied in one motion by a vehicle (not shown) adapted to receive the waste from the divided cart. The divided cart can be grasped by a pincer mechanism, as is well known in the art, the pincers grasping the lower portion 26 of the perimeter wall 21 and taking advantage of the shoulder 27 to expedite lifting of the divided cart. The mechanism will further have an arm, hook, rail or other structure provided so that as the divided cart is inverted over a waste receiving area of the vehicle, the frame handle 66 is engaged so as to rotate the frame 60 about the hinge pin 110, simultaneously lifting both lids 92, 94 and thereby exposing both compartments 32, 34 of the cart 20.
The receiving area of the vehicle will necessarily have a mechanism for diverting the contents of the compartment 32, 34 into separate receptacles within the vehicle.
It should be noted that while the preferred embodiment has been described as having two compartments 32, 34 within the cart 20 and a corresponding two lids 92, 94, the scope of this invention encompasses divided carts having three or more compartments with their associated lids and a divided cart having more than one frame with a quantity of associated lids. For example, a larger divided cart can have two frames associated with four or more lids. This might be required in instances where the receptacles on the vehicle are not adjacent one another, and it would be necessary to open groups of lids independently.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the foregoing description and drawings without departing from the spirit of the invention as defined in the appended claims.
