## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application incorporates by reference and claims priority to U.S. Provisional Application No. 61/814,196 filed on Apr. 19, 2013.


BACKGROUND OF THE INVENTION
The present subject matter relates generally to commercial waste systems. Specifically, the present disclosure includes a commercial waste system including a commercial waste container and a commercial waste vehicle.
Typically, commercial waste containers, known colloquially as dumpsters, are large containers that hold mixed waste. For example, the containers can hold a combination of food waste, recyclables, yard waste, and other waste. Waste containers are often used for waste collection at multi-family dwellings, businesses, restaurants, construction sites, and other locations that generate relatively large amounts of waste over a relatively short time. Traditionally, in order to reduce the amount of waste for final disposal recoverable materials (recyclables) are sorted out of the waste stream prior to garbage pickup. To do so typically requires multiple containers. Accordingly, businesses wishing to separate waste into multiple categories are required to pay for the additional containers, at additional cost to the business. Also, because of their relatively large size, maintaining multiple waste containers for sorting different types of waste is often infeasible, given space constraints at commercial locations.
Additionally, waste collection vehicles are used to collect waste from the containers on a regular schedule. Waste collection vehicles may be of rear load or front load configuration. Traditionally waste collection vehicles, especially in urban environments that afford collection access through alleyways and streets, which allow only limited maneuverability, are rear load configuration. Generally, commercial businesses in urban environments, especially older urban environments are serviced by rear-loading vehicles due to a rear-loading vehicle's ability to more readily operate and maneuver in more restricted areas; in other words areas that have reduced clearance due to building overhangs, fire escapes and overhead utility wires, and multiple building loading and unloading access points. Because of the expense and multiple container requirement involved in sorting waste, waste collection companies typically offer and businesses typically purchase service that collect all waste commingled in one container. Accordingly, collection of multiple (sorted) types of waste (some being described as recoverable or recyclable) typically requires scheduling multiple collections as a separate vehicle is used to collect the recoverable material. This adds further expense as a result of the need to utilize multiple vehicles and multiple conventional collection containers to collect the sorted materials. Because of the additional expense, and inadequate container storage space available to accommodate multiple containers typically associated with waste sorting, many commercial entities forego the process, unnecessarily increasing the amount of waste sent to landfills for final disposal.
Accordingly, there is a need for a waste container divided into multiple compartments to collect waste and/or other multiple types of recoverable (recyclable) materials without comingling and a rear loading truck that includes a divided collection hopper and a divided body with two distinct storage chambers, allowing for collection of the multiple types of waste from the divided container without comingling the collected materials, as described herein.

DETAILED DESCRIPTION OF THE INVENTION
To meet the needs described above and others, the present disclosure provides a commercial waste system 10 including a waste container 12 and a waste vehicle 14. As shown in FIGS. 1 and 2A, the waste container 12 includes an interior volume 24 that may be divided by a container divider 32 into at least two container chambers, for example a first container chamber 34 and a second container chamber 36, to collect waste and/or other multiple types of recoverable (recyclable) materials without comingling. Additionally, the rear loading waste vehicle 14 (FIG. 3) includes a hopper divider 44 and a storage divider 56 such that collection of the multiple types of waste from the divided container does not comingle the collected materials.
The waste container 12 includes a body including a front wall 16, a rear wall 18, a bottom surface 22, and two container side walls 20. As shown in FIG. 2B, the rear wall 18 may include an upper portion 26 and lower portion 28, wherein the upper portion 26 and the lower portion 28 form an obtuse angle 30 within the rear wall 18. In other words, an angle between an inner surface of the upper portion 26 and an inner surface of the lower portion 28 is obtuse. The inclusion of the obtuse angle 30 increases the interior volume 24, and thus the storage capacity, of the waste container 12, as compared to when a rear wall 18 is within one plane.
Additionally, the rear wall 18 may be taller than the front wall 16. The top edges of the front wall 16, rear wall 18, and side walls 20 define a container opening that is angled relative to the base such that the front is lower than the rear. The angled container opening provides an increase in container capacity while maintaining a standard loading height front edge of the container 12. Additionally, the rear wall 18 helps to direct waste into and out of the container 12 during loading and unloading. Some embodiments of the waste container 12 include a relatively taller, sectioned rear wall 18, which allows the container's 12 width and length dimensions to remain similar to those of industry's conventional waste container 12. In some embodiments, the container 12 design also maintains a standard loading height while increasing the overall interior volume 24 of the waste container 12. Maintaining standard dimensions, including width, length, and loading height, may be critical in service areas where space to store a single waste container 12, let alone multiple waste containers 12, is minimal.
The bottom surface 22 is generally rectangular when viewed from above. Casters or other wheels may be attached to the bottom surface 22 near corners to allow for relatively easy movement of the container 12. The bottom surface 22 is formed from a durable material, such as steel, but other materials with similar properties (i.e., stable, weather-resistant, strong, etc.) are contemplated.
The waste container 12 is typically made of steel or other durable materials. The interior volume 24 of the waste container 12 is preferably about three cubic yards, but may be larger or smaller without departing from the scope of the invention. The container 12 is preferably dimensioned such that the overall width is approximately equal to the width of an industry standard waste container 12.
The waste container 12 may also include one or more container divider 32 disposed between the front wall 16 and rear wall 18 or between the two side walls 20. Preferably the container divider 32 is arranged to be substantially parallel with the side walls 20. As shown in FIG. 1, the container divider 32 is used to divide the container into a first container chamber 34 and a second container chamber 36. The container divider 32 is in contact with the front wall 16, the rear wall 18, and the bottom surface 22 such that the waste container 12 is divided into two container chambers. The container divider 32 allows the container 12 to retain material (e.g., waste and /or (recoverable) recyclables) in two separate compartments without the materials intermingling.
For example, the first container chamber 34 may be used to retain non-recyclable waste, while the second container chamber 36 may retain recyclables. While the waste container 12 shown in FIG. 1 is divided so that the first container chamber 34 has a volume that is approximately double the volume of the second container chamber 36, it is contemplated that other ratios could be used. In particular, when the waste container 12 is divided into two container chambers, the volume of the first container chamber 34 is preferably greater than 50% of the interior volume 24, and more preferably in a range of about 60% to about 70% of the interior volume 24.
Additionally, as shown in FIGS. 2A-2B, the waste container 12 may include a lid 37 that covers the container opening. The lid 37 is, for example, hingedly connected to the waste container 12 so that it can be easily opened without being separated from the waste container 12 or misplaced. When the lid 37 is connected to the rear wall 18 of the waste container 12 with a hinge, the lid 37 will open relative to the waste container 12 to allow for unloading when the waste container 12 is tipped forward. The lid 37 can be a single color divided piece, covering the entire opening, or two separate colored lids 37, separated such that each of the container chambers has a separate lid 37. The lid(s) 37 help to contain odors, protect the waste and/or recoverables (recyclables) from the elements, and help prevent animals from entering the waste container 12. Additionally, color of the lid 37 serves as a visual indicator to users, which helps delineate what materials go in each container chamber. The waste container 12 preferably also includes features such as handles disposed on the side walls 20 to allow waste collectors and other users to roll the waste container 12 relatively easily.
The waste container 12 may include a trunnion bar 52 attached along a top edge of the front wall 16, as shown in FIG. 1. For example, the trunnion bar 52 may be permanently welded to the top edge of the front wall 16. Alternatively, or in addition to, as shown in FIG. 6B, the waste container 12 may also include a slide bar receiver 38, wherein the slide bar receiver 38 is generally tubular to receive a slide bar 39. For example, as shown in FIGS. 6A-6C, the waste container 12 may include a trunnion bar 52 connected to a top edge of the front wall 16 and a slide bar receiver 38 connected to a top edge of at least one container side wall 20. As shown in FIGS. 6A-6C, a slide bar 39 may be inserted into the slide bar receiver 38.
In an example, the trunnion bar 52 extends horizontally, widthwise relative to the container beyond each side wall 20 or the front wall 16 on either side of the waste container 12. The trunnion bar 52 is used to connect the waste container 12 to the waste vehicle 14 and to hold the waste container 12 substantially in place on the hopper 42 of waste vehicle 14 during waste collection.
For example for use with containers 12 containing a divider 32, as shown in FIG. 4A, the trunnion bar 52 is inserted into the openings 68 in the hopper side wall 50, such that the interior volume 24 of the waste container 12 is emptied into both the first hopper chamber 46 and the second hopper chamber 48. Alternatively, for use with non-divided containers 12, as shown in FIGS. 7A-7B, a slide bar 39 is inserted into the slide bar receiver 38, such that the entire interior volume 24 of the waste container 12 may be emptied into either of the chambers, for example, the first hopper chamber 46.
As shown in FIG. 3, the waste containers 12 are designed for use with rear-loading waste collection vehicles 14. The waste vehicle 14 preferably has a relatively large divided storage container 54 with a rear opening for loading materials (waste and/or recoverables (recyclables)) into the hopper 42. Additionally, as shown in FIGS. 4A-4B, the vehicle 14 includes a mechanical lift 62 to empty the contents (waste-recyclables) from waste containers 12 without the operator having to lift the container 12 by hand. The mechanical lift 62 allows lifting of relatively large and heavy containers 12, which are a practical necessity for commercial businesses. As shown in FIG. 5, the waste vehicle 14 may be used with conventional waste containers 12 that do not include a container divider 32.
The collection vehicle 14 includes a large storage container 54 used to hold and store materials from the emptied containers 12. The storage container 54 is preferably divided into distinct storage chambers by a storage divider 56. For example, the storage container 54 may be divided into a first storage chamber 58 and a second storage chamber 60. Further, when the waste container 12 is attached to the waste vehicle 14, the container divider 32 and storage divider 56 are within the same vertical plane.
The vehicle 14 further includes a hopper 42 at the rear opening of the vehicle 14. The hopper 42 includes a hopper divider 44 that may separate the hopper 42 into a first hopper chamber 46 and a second hopper chamber 48. The hopper divider 44 may be tapered (or include a cutaway portion) to allow containers 12 to rotate into position for emptying, while still maintaining a division between the first hopper chamber 46 and the second hopper chamber 48. The lateral position of the hopper divider 44 is preferably aligned with in a first plane, wherein the storage divider 56 is contained within the first plane. Similarly, the hopper divider 44 is preferably substantially aligned within the same plane as the container divider 32 when the container 12 is being emptied into the waste vehicle 14.
The vehicle 14 may further include a locking mechanism used to retain and release the waste container 12 during the emptying process. The locking mechanism may include the slide bar receiver 38 of the waste containers 12, openings 68 within the hopper side walls 50, and the slide bar 39. The locking mechanism may include the trunnion bar 52 and the openings 68 within the hopper side walls 50. For example, as shown in FIGS. 7A-7B, the slide bar 39 may be inserted through openings 68 in the hopper side walls 50 and the slide bar receiver 38 to secure the waste container 12 to the waste vehicle 14. Alternatively, the trunnion bar 52 may engage with the openings 68 of the hopper side walls 50 to secure the waste container 12 to the waste vehicle 14. Once the waste container 12 is connected to the vehicle 14 via the locking mechanism, the mechanical lift 62 may be used to rotate and partially invert the container 12.
The mechanical lift 62 includes a lift bar 66 that applies force near the bottom of the front wall 16 or side wall 20 of the waste container 12 that has been locked to the vehicle 14. The mechanical lift 62 further includes two side bars 64, wherein a first end 70 of the side bars 64 are attached to the vehicle 14 and the second ends 72 of the side bars 64 are connected to the lift bar 66. The side bars 64 may be attached to any part of the vehicle 14 near the rear opening. In an example, the side bars 64 may attach to the hopper 42. As shown in FIGS. 8A-8B, the side bars 64 are attached to the vehicle body such that upon raising the lift bar 66, the lift bar 66 pivots about the connection to the vehicle 14. Further, as the lift bar 66 is raised, the lift bar 66 slides along an outer surface of the body of the container 12 as the waste container 12 is raised and at least partially inverted.
The force of the lift bar 66 is applied in an outward and upward direction, causing the waste container 12 to rotate or pivot about the axis defined by the trunnion bar 52 or slide bar 39, depending on which locking mechanism is used. Force is preferably applied using hydraulic or pneumatic pumps. However, other means of applying force are contemplated. The waste container 12 rotates about the axis defined by the trunnion bar 52 or the slide bar 39 until the side walls 20 or front wall 16 makes contact with stops affixed to the vehicle 14. The stops are specifically positioned to prevent the waste container 12 from rotating so far that the waste container 12 no longer returns to its upright position using only the force of gravity.
As shown in FIGS. 8A-8B, as the lift bar 64 raises and rotates the waste container 12 about the trunnion bar 52, the trunnion bar 52 may slide from an opening first end 74 in the hopper side wall 50 to an opening second end 76. Although the figures depict both the opening first end 74 and opening second end 76 are closed, it is contemplated that at least the first opening 74 or the opening second end 76 may be open ended. When the waste container 12 is connected to the waste vehicle 14 in an upright position, the trunnion bar 52 is positioned near the opening first end 74 of the opening 68 of the hopper side wall 50, as shown in FIG. 8A. As the waste container 12 moves into an inverted position, the trunnion bar 52 moves towards the opening second end 76 of the opening 68, as shown in FIG. 8B. Analogous movement of the slide bar 39 is achieved when the waste container 12 is connected to the waste vehicle 14 by way of the slide bar 39, wherein the waste container 12 rotates about the slide bar 39 during the lifting and emptying of the waste container 12 into the waste vehicle 14.
As the waste container 12 is rotated upward, the waste and/or recoverables (recyclables) fall from the container 12 into the vehicle 14. When the waste container 12 includes a container divider 32 and the container divider 32 is aligned with the hopper divider 44, the materials from each of the container chambers remain separated, and the two types of material collected are not intermingled. Once the waste and/or recoverables-recyclables have been emptied from the waste container 12, the lift bar 66 of the mechanical lift 62 returns to its normal position, which allows the waste container 12 to rotate back to an upright position. Once the waste container 12 has returned to its normal orientation, the trunnion bar 52 or slide bar 39 may be removed from the openings 68, and the waste collection vehicle 14 can continue on its route.
The waste vehicle 14 preferably also includes a compacting apparatus used to compact the collected waste and/or recoverables (recyclables). The compacting apparatus may include a single compactor that compacts materials collected in both storage chambers, or separate compactors for each the first storage chamber 58 and the second storage chamber 60. The compactor moves waste and/or recoverables (recyclables) from the hopper 42 into the storage chambers and compacts the materials in the storage chambers.
It should be noted that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. For example, various embodiments of the method and device may be provided based on various combinations of the features and functions from the subject matter provided herein.
