Abstract
Description
- This application claims priority to U.S. Provisional Application Ser. No. 60/857,879, filed Nov. 9, 2006, the disclosure of which is incorporated herein by reference in its entirety.
- The present invention relates to containers, and in particular, the bolsters for construction containers.
- Large storage containers, including boxes and cabinets, used in the construction industry are often formed of steel sheet. The floor, walls and ceiling (or lid) of the container can be formed either from a single sheet of steel that is bent at intersecting edges of these surfaces or from multiple pieces of sheet steel that are welded together. Many containers have bolsters underlying the floor, and some will include casters beneath the bolsters. Typical sizes for such a cabinet or box can range from 5 ft3 to 150 ft3 or even larger. Exemplary storage containers include those sold under the name JOBOX™ by Delta Consolidated Industries, Jonesboro, Ark. and those sold under the name JOBMASTER™ by Knaack Manufacturing, Crystal Lake, Ill.
- Large storage containers may be heavy and difficult to move, especially when fully loaded with construction materials. A forklift may be employed to move large storage containers; however, the bolsters and/or casters may make it difficult to orient the forklift prongs under the container to achieve proper balance and a secure lift. The forklift prongs and/or the location of the container may limit the container to be lifted from only one or two sides. Operators may be required to reorient the container so that the desired container side is facing the forklift. This may be difficult and/or time-consuming, especially if space for moving and reorienting the container is limited.
- According to embodiments of the invention, a container includes a receptacle having sidewalls and a floor; and a plurality of bolsters attached to an underside portion of the floor. The bolsters include a lower panel spaced apart from the underside portion of the floor, at least two projections from the lower panel that form a first entry window, and a pair of walls extending from the lower panel to the floor that form a second entry window that is substantially perpendicular to the first entry window.
- In particular embodiments, the second entry window forms an opening toward a side of the container and the first window forms an opening toward a front of the container. The lower panel may include a crease between the at least two projections. At least two bolsters of the plurality of bolsters may be formed from a single sheet of metal and/or at least one of the plurality of bolsters may be formed as a unitary member.
- In some embodiments, the projections extend at least 0.25 inches from the lower panel. The projections may include apertures that are configured to receive casters. The bolster walls may be angled. The first and second entry windows may be configured to receive a prong from a forklift.
- According to further embodiments of the present invention, a container includes a receptacle having sidewalls and a floor, the sidewalls defining a front and a side of the container. A plurality of bolsters are attached to an underside portion of the floor. The bolsters form at least a portion of a first entry window accessible from the front of the container and form at least a portion of a second entry window accessible from the side of the container.
- According to still further embodiments of the present invention, a bolster configured to attach to an underside portion of a container includes a lower panel, at least two projections from the lower panel that form a first entry window, and a pair of walls extending from the lower panel and configured to attach to the floor. The pair of walls form a second entry window that is substantially perpendicular to the first entry window.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain principles of the invention.

FIG. 11 is a top perspective view of a container and bolsters according to still further embodiments of the present invention. - The present invention now will be described hereinafter with reference to the accompanying drawings and examples, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
- Like numbers refer to like elements throughout. In the figures, the thickness of certain lines, layers, components, elements or features may be exaggerated for clarity. Broken lines illustrate optional features or operations unless specified otherwise.
- The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. As used herein, phrases such as “between X and Y” and “between about X and Y” should be interpreted to include X and Y. As used herein, phrases such as “between about X and Y” mean “between about X and about Y.” As used herein, phrases such as “from about X to Y” mean “from about X to about Y.”
- Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
- It will be understood that when an element is referred to as being “on”, “attached” to, “connected” to, “coupled” with, “contacting”, etc., another element, it can be directly on, attached to, connected to, coupled with or contacting the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on”, “directly attached” to, “directly connected” to, “directly coupled” with or “directly contacting” another element, there are no intervening elements present. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.
- Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of “over” and “under”. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal” and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.
- It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a “first” element, component, region, layer or section discussed below could also be termed a “second” element, component, region, layer or section without departing from the teachings of the present invention. The sequence of operations (or steps) is not limited to the order presented in the claims or figures unless specifically indicated otherwise.
