CONSTRUCTION WASTE REMOVAL CONTAINER

[0001] 1. Field of the Invention

[0002] The present invention relates to the field of waste removal containers and more particularly to collapsible waste removal containers for use at construction sites, commercial sites, industrial waste sites, town houses, multi-family homes and condominiums.

[0003] 2. Description of the Related Art

[0004] At construction sites, such as high-rise buildings for new construction, remodeling, building refurbishment or modernization, and at industrial waste sites, one of the problems faced by the builder, construction company or business is the removal of substantial amounts of waste, debris and garbage. Conventional ways for waste, debris and garbage removal at construction and industrial sites are accomplished by locating multiple containers or bins at various waste collection locations at the construction or industrial site. Typical containers or bins are approximately twenty feet long, six to eight feet wide and three to eight feet deep. These containers are typically referred to as “roll-off” containers and may have wheels to make the stationary roll-off containers into mobile roll-off containers. Such roll-off containers usually have three standard sizes: one size is twenty cubic yards, a second size is thirty cubic yards and the other size is about forty cubic yards.

[0005] Since all roll-off containers have different trash weight and capacity, which is dependent upon the ability of an associated “roll-off truck” to pick up the loaded containers and upon state and/or local restrictions, the size of roll-off container selected depends upon the weight of trash or other materials to be dumped therein. For example, the twenty yard roll-off containers are typically most efficiently used on construction sites for heavy waste materials, such as broken masonry, concrete and asphalt; earth; bricks and tile. The thirty and forty yard roll-off containers are typically constrained to receiving lighter-weight materials, such as scrap lumber, plasterboard, broken shingles, tree branches and trimmings, business and household garbage and typical packaging waste such as corrugated cardboard, cardboard and packing materials. Regardless of which roll-off container is selected, these roll-off containers are too heavy for trucks having front or rear end loaders to lift and empty the construction waste materials. Instead, an associated “roll-off truck” will pick up the roll-off container.

[0006] Conventional roll-off containers are made as single integrated units constructed of heavy materials such as metal and cannot be disassembled. As such, each roll-off container has a fixed footprint that requires a set amount of space at the construction/industrial site regardless of whether that roll-off container is in use or is waiting to be used. This causes a problem at many construction and industrial sites that have limited space available to place waste containers, much less store empty roll-off containers. More importantly, as roll-off containers are single integrated units, the roll-off containers are typically transported one at a time to the construction/industrial site whether empty or loaded with debris, which squanders time, fuel, resources and money.

[0007] Embodiments of the present invention address deficiencies of the art in respect to waste removal containers and provide a novel and non-obvious system and apparatus for receiving and containing waste. In one embodiment of the invention, a waste removal container system can be provided. The system can include a plurality of detachable walls and a detachable base wall that can include a locking mechanism to interlock with plurality of detachable walls. The locking mechanism can include a plurality of retaining flanges coupled to the topside of the base wall, which are arranged to interlock with a bottom edge of at least one of the plurality of walls. The plurality of walls can include hinging receptacles located on the side-edges of the plurality of walls. The plurality of walls can include a pair of detachable side walls, a detachable front wall and a detachable back wall. The system further can include a hinging pin configured for engaging a first hinging receptacle coupled to a side-edge of one of the plurality of walls and a second hinging receptacle coupled to a side-edge of another of the plurality of walls. The hinging receptacles can receive retaining pins to interlock one detachable wall to the next to form interlocking corner joints for the waste removal container system.

[0008] In another embodiment of the invention, a method for deploying a waste removal container system can be provided. The method can include transporting one or more collapsible waste containers to a construction site, assembling the collapsible waste removal container by connecting a set of wall members to the base wall and connecting the wall members to the corresponding adjacent wall member. The process yet further can include positioning the one or more collapsible waste containers to receive waste and receiving waste. In embodiments, assembling the collapsible waste removal container can include sliding a bottom end of a front wall into a retaining flange of the base wall. This embodiment further can include sliding a bottom end of a side wall into another retaining flange of the base wall. The hinging receptacles of front wall can be aligned with the hinging receptacles of side wall. Once aligned, a hinging pin can be deployed through the aligned hinging receptacles to interlock a side-edge of front wall with a side-edge of side wall to form a corner joint. This embodiment further can include sliding a bottom end of a side wall into yet another retaining flange of the base wall. The hinging receptacles of front wall can be aligned with the hinging receptacles of side wall. Once aligned, a hinging pin can be deployed through the aligned hinging receptacles and to interlock a second side-edge of front wall with a side-edge of side wall to form a corner joint.
