## Title
Side-to-side flip roof for waste containers

## Abstract

A side-to-side flip roof has the ability to be manually opened from both sides of a waste container by use of a manually operated handle. A carriage, carrier assembly, and pivot system allows for filling of the container from either side. This product has a plastic full-length roof to resist water ingress to meet legal storm water preparedness requirements. It holds up under extremely rigorous usage. For weight restriction reasons, plastic sheeting appears the best material to use for this roof. The roof mechanism allows a single person to open the roof with height of the box up to 8′, or more. This flip roof is additionally lockable.

BACKGROUND
1. Technical Field
The technology of this disclosure pertains generally to waste transport and more particularly to covered waste transport manually accessible to two sides.
2. Background Discussion
Waste containers must typically be covered to prevent littering their contents while being transported. However, such covered containers typically allow loading of the container only from one side or the other. In many situations, to achieve waste loading, such covered containers must be physically rotated end-to-end to allow the loading of an otherwise misoriented container.
Even worse are waste containers that do not have attached lids. Such containers are prone to transport littering, and must otherwise be covered by a separate lid or roof structure, or covered with a tarp of some sort. While such containers do not require reorientation, they do require the additional step of covering the waste to prevent transport road litter, and the storage of the container covering when it is not in use.
Littering generated from the transportation of waste containers is a legal requirement in many states, thereby making it mandatory that waste containers be covered.
Additionally, waste containers may become contaminated by rain water, frequently turning the waste into a sodden mess. For this reason, traditional tarps are of little use, as they must be further supported to shed rain, otherwise pooling and eventual water leakage into the waste likely ensues.
BRIEF SUMMARY
A side-to-side flip roof is described here. The flip roof is accessible from either side of a waste container, and is easily manually manipulated between open and closed from either side of the waste container.
A side-to-side mechanism is used to provide most of the translation of the flip roof roughly parallel to the top of the waste container through a primary translational motion. After the limit of the primary translational motion is reached, the mechanism continues translation in the same direction with a secondary translational motion. This secondary translational motion allows for a translation of the pivot of the flip roof to extend beyond the extent of the waste container, and thereby permits the flip roof to be readily flipped to a substantially vertical position, thereby opening the waste container for usage.
The side-to-side mechanism is mounted to both sides of the waste container, typically by welding or other suitable mechanical fastening.
After waste container usage, the flip roof is again manually flipped into a horizontal position, and rolled to a covered position with the side-to-side mechanism. In the covered position, the waste container is substantially water tight, resisting water ingress and thereby preventing water contamination of the waste container contents.
Further aspects of the technology described herein will be brought out in the following portions of the specification, wherein the detailed description is for the purpose of fully disclosing preferred embodiments of the technology without placing limitations thereon.

DETAILED DESCRIPTION
Refer now to FIGS. 1A, 1B, and 1C. FIG. 1A is an isometric view 100 of a prior art waste container 102 that has affixed to it a side-to-side mechanism 200 in two distal places, and a flip roof 300 shown in a closed position. In different viewing orientations, FIG. 1B is a side view of the waste container 102 of FIG. 1A, and FIG. 1C is an end view of the waste container 102 of FIG. 1A. In all of these views FIG. 1A, FIGS. 1B, and 1C, the flip roof 300 is shown in the closed position, where the flip roof 300 completely covers the prior art waste container 102. Actuation of the flip roof 300 is manually accomplished by pulling on a handle 104.
Refer now to FIGS. 1D and 1E. FIG. 1D is an isometric view of the waste container 102 of FIG. 1A, wherein the flip roof 300 has been partially rolled open using a manual handle 104. Here, the flip roof 300 has been translated substantially parallel to the top 106 of the waste container 102 by translational movement of the side-to-side mechanism 200. Similarly, FIG. 1E is an end view of the waste container 102 of FIG. 1D, wherein the flip roof 300 has been partially rolled open using the manual handle 104.
Refer now to FIG. 1F, which is an isometric view of the waste container 102 of FIG. 1A or FIG. 1D, wherein the flip roof 300 has been manually rolled open and flipped substantially vertically more or less 90° from the partially rolled open position shown previously in FIG. 1D. It should be noted that the vertical rotation of the flip roof 300 has been manually accomplished by the use of the manual handle 104, which has been pivoted upward about a handle pivot 108, so as to not otherwise rest on the ground 110 roughly parallel to the bottom of the waste container 102.
Refer now to FIG. 1G, which is an end view of the waste container 102 of FIG. 1F, wherein the flip roof 300 has been rolled open and flipped substantially vertically using the manual handle 104. After manually opening and flipping the roof 300, the manual handle 104 has been pivoted about the handle pivot 108 into a storage position, and is retained by a locking a tab.
Now that the overall description of what is to be accomplished with the flip roof 300 movement relative to the waste container 102, additional details of the side-to-side mechanism 200 can be described.
Refer back now to FIG. 2A, which is an enlarged side view of the side-to-side mechanism 200, which is attached to the top 106 of the prior art waste container 102. This attachment between of the side-to-side mechanism 200 and the top 106, not shown here, is typically performed by welding, but may be otherwise mechanically attached using nuts, bolts, or other mechanical fasteners. Here, only a portion of the flip roof 300 and one corner of the prior art waste container 102 are shown. The flip roof 300 is shown here in the closed position.
Refer now to FIG. 2B, which is a spaced-apart isometric view of the side-to-side mechanism 200 previously seen in FIG. 2A. A carriage 202 is constructed of a carriage slide base 204, to which is affixed two angles 206, 206′ that face each other. A carrier stop 208 is formed by a bolt 210 that passes through the first angle 206, then a sleeve 212, then through the second angle 206′, and is finally secured by a nut 214. An additional similar carrier stop 208′ is found at the opposite side of the carriage 202.
A carrier assembly 216 is shown spaced above the carriage 202. Here, the carrier assembly 216 is shown disassembled from the carriage 202 for the sake of clarity. The carrier assembly 216 is comprised of a cam follower 218 that rides within the channel 220 formed by the affixed and spaced apart facing two angles 206 and 206′. The cam follower 218 is affixed to a carriage bar 222, which is in turn affixed to a carriage slide 224. It should be noted that the cam follower 218 is typically rotational in nature, able to turn freely relative to the carriage bar 222, within the channel 220. On the opposite side of the cam follower 218 are two additional cam followers 218′, which allow for both of the angles 206 and 206′ to act as vertical constraints to the carrier assembly 216 sliding motion. This vertical constraint is formed by the cam follower 218 and additional two cam followers 218′ riding in the channel 220 of the carriage 202.
In assembly, the carrier assembly 216 would typically be inserted by the cam followers 218 and 218′ being inserted within the channel 220 of the carriage 202 with one of the carrier stops 208 or 208′ being temporarily removed, and replaced after assembly.
Primary Translational Motion
A primary translational motion occurs as the carrier assembly 216 translates within the channel 220 of the carriage 202. The limits of the primary translational motion occur by contact of the carriage bar 222 against either of the carrier stops 208 or 208′ at the extremes of movement.
Refer again to FIGS. 1A, 1D, 1E, and 2B. This primary translational motion is of an insufficient range to allow for flip roof 300 clearance of the waste container 102 as desired as most clearly shown in FIG. 1E. It is recognized that the primary translational range could be increased; however, such increase would then make the carriage 202 wider than the waste container 102, which would lead to a projection of the carriage 202 beyond the lateral extent of the waste container 102, with obstruction possibilities and likelihood of carriage 202 damage due to such projection in typical use.
Refer back again to FIG. 2B. Here, the carriage slide 224 serves as a support for two slide bar mounts, 226 and 226′ at opposite ends of the carriage slide 224. The two slide bar mounts 226 and 226′ in turn support a shaft 228, upon which a hinged roller bearing 230 slides. The shaft 228 is secured in the two slide bar mounts 226 and 226′ with set screws or other manner of attachment, and are not further detailed here to reduce drawing clutter. The carriage slide 224 actual translational sliding motion occurs between the shaft 228 and a pressed bushing 232 that is pressed into the hinged roller bearing 230. The hinged roller bearing 230 finally has a hinge pivot hole 234, through which the flip roof 300 subsequently attaches (not shown here).
Secondary Translational Motion
A secondary translational motion is created by the movement of the hinged roller bearing 230 sliding upon the shaft 228. Here, the hinged roller bearing 230 is constrained in its motion between the slide bar mounts 226 and 226′. This secondary translational motion allows for motion beyond that available to the primary translational motion previously described, which allows for the hinge pivot hole 234 to extend over and beyond the furthest lateral extent of the waste container 102, which in turn allows for the roof assembly to pivot, as previously shown in FIGS. 1F and 1G.
This secondary translational motion allows for the movement of the hinge pivot hole 234 beyond the lateral extent of the waste container 102, yet in the closed position maintains the entirety of the carriage 202 completely within the lateral extent of the waste container 102, thereby protecting the carriage 202 from possible damage that might otherwise occur if the carriage 202 extended beyond the lateral extent of the waste container 102.
Major Components
Refer now to FIG. 3A, which is an exploded isometric view of the flip roof 300 and flip roof frame of FIG. 1A, with the roof shown in the closed configuration. Here, a roof covering 302 is supported over a frame 304 that pivots on roof pins 306 and 306′ at opposite ends of the frame 304. The roof covering 302 is typically a light plastic material with ultraviolet light resistant properties for prolonged outdoors usage in direct sunlight.
Refer now to FIG. 3B, which is an exploded isometric view of the carriage 202 and carrier assembly 216 of FIG. 2B. This view is provided here to better clarify the description previously given above regarding FIG. 2B.
Refer now to FIG. 3C, which is an isometric view of the prior art waste container 102 that allows for the mounting of the carriage and carrier assembly of FIG. 3B to a portion of the top 106 of the prior art waste container 102.
Refer now to FIG. 4, which is a partially exploded isometric view of the prior art waste container 102 to which is attached the side-to-side mechanism 200, which comprises the assembled carriage 202 and carrier assembly 216. The flip roof 300 attaches to the side-to-side mechanism 200 via roof pins 306 and 306′ that allow for rotation in carrier assembly 216 hinge pivot holes 234. The overall rotation of roof pins 306 and 306′ within the hinge pivot holes 234 allows for the overall rotation of the flip roof 300 to an open position substantially 90° to its otherwise closed orientation.
Overall Operation
Now that the details of the side-to-side flip roof have been explained, its operation may be more readily discerned.
Refer now to FIG. 1A, which shows the flip roof 300 in a substantially closed orientation. Refer now to FIG. 1E, where a user pulls on the handle 104 to slide the flip roof 300 aside to the point where the side-to-side mechanism 200 is at the limit of the primary translational motion, otherwise known as when the carriage bar 222 is contacted (or stopped) by one of the carrier stops 208 or 208′ (the carrier stops 208 or 208′ are most easily seen in FIG. 2B).
At this point, continued pulling on the handle 104 by the user pulls the hinged roller bearing 230 on shaft 228 until the hinged roller bearing 230 is stopped by one of the slide bar mounts 226 or 226′ (again most easily seen in FIG. 2B) at the limit of the secondary translational motion. (This resulting secondary translational motion is seen most clearly in FIG. 1G, although here, the flip roof 300 has been pivoted.)
Refer now tot FIG. 1G. Continued pulling on the handle 104 by the user causes the flip roof 300 to pivot. Here, the handle 104 use has been completed, and has been rotated about the handle pivot 108 vertically to a latching stop (not shown) for storage.
In this orientation with the flip roof 300 substantially vertical, the waste container 102 is open and ready for loading. Note that the waste container 102 could have been opened from either side be using the manual handle 104 on the opposite side of the flip roof 300.
After loading the contents of the waste container 102, the steps are essentially reversed, resulting in a container configuration shown again in FIG. 1A, but with the contents of the waste container 102 loaded (not shown). The waste contents are now protected from water ingress by the flip roof 300, as well as inadvertent road littering during transport.
