Description
Field of the Invention
This invention relates generally to portable cargo storage boxes such as tool boxes and, more particularly, to assemblies and apparatus for securing a cargo storage box in the bed of a truck such as a pick-up truck.
Background of the Invention
Known pick-up trucks typically include a cargo bed for storing objects, e.g., cargo, during transportation. The cargo bed includes a substantially rectangular horizontal floor and substantially vertical walls extended from the edges of the floor. Particularly, stationary walls form the front wall and two adjacent side walls, and a removable or hinged tail gate forms the back wall and provides access to the bed floor for cargo loading and unloading. The walls are approximately between one and three feet high and facilitate retaining cargo within the cargo bed.
The cargo bed often is utilized to transport a cargo storage box such as a tool box. One known cargo bed tool box is substantially T-shaped and configured to rest on top of the vertical walls of the cargo bed. Particularly, the tool box includes a substantially hollow central portion and two lips extending from opposite sides of the central portion. The central portion is configured to retain tools, i.e., hammers, wrenches, and screwdrivers, and the lips are configured to be frictionally coupled to the tops of the respective side walls. To install the tool box in the cargo bed, the lips are placed on the tops of the respective side walls so that the central portion of the tool box extends downwardly into the cargo bed. The tool box is substantially easy to install and remove from the cargo bed of the pick-up truck. However, such tool box also is highly visible from side views because the lips of the tool box extend across the top of the cargo bed. Such high visibility is believed to increase the likelihood of theft of the tools retained within the tool box and, sometimes, the tool box itself.
To reduce the likelihood of theft, some pick-up truck tool boxes are permanently installed in cargo beds. However, such permanently installed tool boxes limit the amount of cargo bed space available for transporting other cargo. In addition, such permanently installed tool boxes typically are difficult to remove from the cargo bed, which may be desirable, for example, when unloading the truck at a remote work site. In addition, such tool boxes typically extend across the top of the cargo bed wall, and thus remain visible to potential thieves.
It would be desirable to provide a tool box for the cargo bed of a pick-up truck which does not extend above the walls of the cargo bed. It also would be desirable for such tool box to be easy to install and remove from the cargo bed. It further would be desirable for such tool box to be securable at different locations within the cargo bed.
Summary of the Invention
These and other objects may be attained by a cargo storage box which, in one embodiment, is configured to be releasably secured in the cargo bed of a pick-up truck so that the cargo storage box does not extend above the top of the cargo bed. The cargo bed includes a cargo surface, and first and second walls extend substantially perpendicularly from opposite sides of the cargo surface. The first and second cargo bed walls extend substantially the same distance from the cargo surface, and tops of the cargo bed walls are substantially co-planar.
The cargo storage box, in accordance with one embodiment of the present invention, is sized to be positioned between the first and second cargo bed walls, and includes a base wall and retaining walls extending perpendicularly from the base wall to define a cargo chamber sized to receive, for example, tools. The retaining walls each extend substantially the same distance from the base wall, and top surfaces of the retaining walls are substantially co-planar. The distance between the base wall and the top of each retaining wall is less than the distance between the cargo surface and top surfaces of the cargo bed walls.
The cargo storage box further includes a first locking element and a second locking element. The first locking element is configured to releasably secure a first one of the retaining walls to the first cargo bed wall. The second locking element is configured to releasably secure a second and opposite one of the retaining walls to the second cargo bed wall.
In operation, the cargo storage box is positioned in the cargo bed between the first and second walls of the cargo bed so that the base wall is adjacent the cargo surface and so that the top surfaces of the cargo storage box retaining walls are below the top surfaces of the cargo bed side walls. The first locking element then secures the first retaining wall to the first cargo bed wall and the second locking element secures the second retaining wall to the second cargo bed wall.
The above described cargo storage box may be secured to a cargo bed of a pick-up truck without extending above the walls of the cargo bed. Such cargo storage box also is believed to be easy to install and remove from the cargo bed. In addition, such cargo storage box is securable at different locations within the cargo bed.
