Description

FIELD OF THE INVENTION

The present invention relates generally to covers for containers. More specifically, the present invention relates to covers for large dumpsters such as used in the construction or manufacturing industries, the covers being easily operable by a single person.

BACKGROUND OF THE INVENTION

In the construction industry, large dumpsters are used to collect and contain debris and waste associated with demolition, renovation and/or construction. One such type of dumpster is referred to as a roll-off container, usually featuring a rectangular footprint so as to be easily transportable by truck. Roll-off containers are configured to be delivered and removed via specialized trucks which allow the container to rolled off the truck and put into place. Such trucks utilize tilting beds, cable and winch systems, and/or hooks in order to facilitate loading and unloading the roll-off container from the truck. Alternately, dumpsters may be delivered and removed via a truck having a crane. These dumpsters are sized according to volume, with common container sizes in the United States being between ten and forty yards.

Construction debris may originate from a building site where something is being built, renovated, or demolished. Roll-off dumpsters are also used for various jobs that need much material to be taken away. The material in the roll-off may be taken to a landfill, recycled or otherwise properly disposed of.

While roll-off containers typically include an open top, in certain applications it may be desirable to cover the container, for example to comply with environmental regulations regarding storm water exposure, to provide protection from theft or unauthorized dumping, and/or to otherwise protect against unwanted or unauthorized access to the container or its contents. One such type of cover may be a tarpaulin, which is inexpensive but can be cumbersome to handle and ineffective at securely protecting the container and its contents. Another type of cover in use is constructed of heavy duty steel, which provides excellent security but is expensive and tremendously heavy, requiring specialized equipment to open and close the cover.

A need exists in the industry for an improved cover for large dumpsters.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.

Referring generally to the Figures, embodiments of the present invention are directed to a cover assembly 100 for use with an open-top container 170, such as a large dumpster or roll-off container. Cover assembly 100 generally includes a cover portion 102, a frame portion 120, and an opening mechanism 140.

Cover 102 may be constructed of suitable lightweight yet strong materials such as fiberglass, thin gauge metals such as aluminum or steel, or various plastics. In one embodiment depicted in FIG. 1, cover 102 comprises a single piece. In another embodiment, cover 102 comprises multiple pieces which are joined together to form a large cover, such as depicted in FIG. 1A wherein cover 102 comprises a first part 102 and a second part 104. Cover 102 has an outer surface 108 and an inner surface 110, and may include various ribs, gussets, or other features 112 to increase stiffness. As depicted in the Figures, ribs 112 are disposed on outer surface 108, although ribs or gussets 112 may be included on inner surface 110 in addition to, or in place of, ribs 112 on outer surface 108. Optionally, inner surface 110 of cover 102 may include a reinforcing framework to provide additional stability. Suitable construction techniques for cover 102 may include wet lay-up of fiberglass, stamping of sheet metal in a die, or roto-molding or injection molding for plastics.

Cover assembly 100 also includes a frame 120 configured to support cover 102. As depicted generally in the Figures, frame 120 comprises a plurality of struts, trusses or frame members, in the form of longitudinal rails 122 and lateral crossmembers 124. Additional struts may also be included as necessary to provide suitable strength and rigidity depending upon the desired application. Longitudinal rails 122 are configured to extend along a first, longitudinal direction of container 170, e.g., the length, while crossmembers 124 are configured to space rails 122 apart a distance which corresponds to a second, lateral dimension of the container, e.g., the width. Frame 120 may be constructed of suitable materials such as steel, aluminum, or plastics, especially extruded plastics. Cover 102 may be secured to frame 120 in a number of ways, for example by fastening cover 102 directly to rails 122. Frame 120 may be constructed of smaller individual pieces and configured to be assembled by bolts and/or brackets, in order to allow cover assembly 100 to be shipped more easily and/or at lower cost.

Frame 120 optionally includes a center standoff support 126, configured to provide support to the peak of cover 102. Center support 126 is suitable for use with covers configured with a tall center portion, while covers having a lower center profile may not require the use of center support 126. Also optionally as depicted in FIG. 4, frame 120 may include a transport means 128, so as to allow cover assembly 100 to be picked up and moved with a forklift or similar device. Further, frame 120 may optionally include a handle (not pictured) to facilitate easier opening and closing of cover 102.

Cover assembly 100 also includes an opening mechanism 140, configured to facilitate moving cover 102 between a closed position and an open position. Opening mechanism 140 generally includes at least one beam 142 having an optional tip portion 144, a means for coupling 146 to a container, a pivot or hinge 148, and a plurality of roller assemblies 150. As depicted in the Figures, opening mechanism 140 includes a plurality of beams 142, however a single beam 142 may be sufficient for smaller-sized covers. Means for coupling 146 is disposed on a first end of beam 142, and as depicted in FIGS. 1-3 may comprise a bracket which is configured to be bolted directly to container 170. As depicted in FIG. 4, the means for coupling comprises a clamp or shackle which is configured to be removably placed on a side of container 170.

At a second end of beam 142 is an optional tip portion 144 having a thin profile as compared to beam 142. With cover assembly 100 in the closed position, tip portion 144 allows cover 102 to sit nearly flush with an edge of container 170. Tip portion 144 may comprise a separate component secured to beam 142, or beam 142 may be modified to include a thin profile so as to create tip portion 144. In embodiments lacking tip portion 144, beam 142 may rest directly on an edge of container 170.

Roller assembly 150 is configured to provide smooth opening and closing of cover assembly 100, and generally includes a mounting bracket 152, an upper roller 154, and a lower roller 156, secured with suitable fasteners 158. As depicted in FIGS. 1-4 and 7, roller assembly 150 proximate the means for coupling is configured such that mounting bracket 152 is secured to beam 142, upper roller 154 is disposed above crossmember 124, and lower roller 156 is disposed below crossmember 124 and above beam 142. Also as depicted in FIGS. 1-4 and 7, roller assembly 150 proximate tip portion 144 is configured such that mounting bracket 152 is secured to crossmember 124, upper roller 154 is disposed below crossmember 124 and above beam 142, and lower roller 156 is disposed below beam 142.

In another embodiment, frame 120 may be configured to include an opening mechanism and a means for coupling with a container, such that frame 120 is directly coupleable with the container.

Referring now to the operation of cover assembly 100, FIG. 5 depicts cover assembly 100 in a closed position. An operator pulls or pushes on any of frame 120, cover 102 or handle if equipped, which causes frame 120 and cover 102 to move horizontally with respect to opening mechanism 140. As described above, opening mechanism 140 is secured to container 170 by way of means for coupling 146. Roller assemblies 150 provide smooth operation, allowing a single person to open and close even a large cover. As frame 120 and cover 102 slide horizontally toward an open position, such as in FIG. 6, once the middle of frame 120 and cover 102 are nearing the edge of container 170 (and therefore pivot 148 on opening mechanism 140), frame 120 and cover 102 will begin to be balanced over the pivot point. Continued movement toward the open position will cause frame 120 and cover 102 to move past the pivot point and begin to tilt from a horizontal orientation to a vertical orientation.

FIGS. 7-8 depict cover assembly 100 in a fully open position, with means for coupling 146 of opening mechanism 140 being attached to container 170 but the remainder of cover assembly 100 being out of the way, allowing access to the inside of container 170. Mounting brackets 152 of opening mechanism 140 and the configuration of frame 120 act as stops, preventing frame 120 and cover 102 from sliding off of beams 142 and thereby container 170. Optionally, one or more counterweights may be added to frame 120 and/or handle in order to aid the opening of cover assembly 100.

Referring now to FIGS. 9-16, another embodiment of cover assembly 100 is depicted, having a free-standing opening mechanism 180 configured to be coupled to the ground or other suitable structure. Opening mechanism 180 generally includes a beam 182 pivotably coupled to a vertical support 184 via pivot 186, and a base 192. Support 184 may be height adjustable to facilitate usage with containers of varying sizes, and support 184 may include a first portion 188 adjustably coupleable to a second portion 190 at a plurality of different positions and secured with suitable fasteners. Collectively, means for coupling 146 described above and support 184 may constitute a means for supporting frame 120 and/or cover 102.

As best depicted in FIGS. 15-16, each roller assembly 150 is configured such that mounting bracket 152 is secured to beam 142, upper roller 154 is disposed above crossmember 124, and lower roller 156 is disposed below crossmember 124 and above beam 142. Alternately, upper roller 154 may be omitted and simply comprise a bolt.

In operation, free-standing opening mechanism 180 performs similarly to the embodiments depicted in FIGS. 1-8. As frame 120 and cover 102 slide horizontally toward an open position, such as in FIGS. 9-10, once the middle of frame 120 and cover 102 are nearing the edge of container 170 (and therefore pivot 148 on opening mechanism 140), frame 120 and cover 102 will begin to be balanced over the pivot point. Continued movement toward the open position will cause frame 120 and cover 102 to move past the pivot point and begin to tilt from a horizontal orientation toward a vertical orientation, such as depicted in FIGS. 13-14. Mounting brackets 152 of opening mechanism 180 and the configuration of frame 120 act as stops, preventing frame 120 and cover 102 from sliding off of beams 142 and thereby container 170. Optionally, one or more counterweights may be added to frame 120 and/or handle in order to aid the opening of cover assembly 100.

The free-standing opening mechanism 180 is especially advantageous for use at permanent facilities which frequently fill containers, as cover assembly 100 may simply be opened such that cover 102 and frame 120 are out of the way, the container removed, and a new empty container placed next to cover assembly 100.
