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.
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.
In one embodiment, a cover assembly for a container comprising a frame, a cover coupled to the frame, and an opening mechanism in communication with the frame and including a means for coupling with the container, wherein the cover is configured to be movable between a closed position which substantially covers an opening of the container, and an open position which allows access to a substantial portion of the opening of the container.
In one embodiment, a cover assembly for a container, comprising a frame, a cover coupleable to the frame, and an opening mechanism in communication with the frame and including a support for coupling the cover assembly to a structure separate from the container, wherein the cover is configured to be movable between a closed position which substantially covers an opening of the container, and an open position which allows access to a substantial portion of the opening of the container.
In one embodiment, a kit for a cover assembly comprising a plurality of support struts, the struts configured to be joined together to construct a frame, a cover coupleable to the frame, and an opening mechanism in communication with the frame and including a means for supporting the frame, wherein the cover is configured to be movable between a closed position which substantially covers an opening of a container, and an open position which allows access to a substantial portion of the opening of the container.
The invention may be more completely understood in consideration of the following detailed description of various embodiments of the invention in connection with the accompanying drawings, in which:
While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope 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
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
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
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
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,
Referring now to
As best depicted in
In operation, free-standing opening mechanism 180 performs similarly to the embodiments depicted in
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.
