This invention relates to the area of storage systems for home and industrial use, specifically those designed to be retrofitted to existing structures, such as garages or storage units.
The typical storage scenario involves identifying square footage of a building to be set aside for storage, where items will be stacked on the floor. A storage structure supported from the ceiling of a building increases the capacity of storage space by permitting items to be placed well above the floor, for example in the ceiling area of a garage.
There is a long history of such storage structures in the art, including U.S. Pat. Nos. 6,715,427 and 6,435,105 to Mikich, et al., 6,725,608 to Kraus, 7,357,262 to Fratilla, 7,543,538 and 7,421,957 to Baez, and. These are the most recent inventions, and they primarily address the garage ceiling storage problem. Each has their own mechanism for attachment to the ceiling rafters, and unique rack designs. The Baez patents also show a splicing technique for beams.
The present invention adapts the state of the art and moves it forward by supplying a simplified splicing system to allow easy connection of improved angle iron connectors and C-shaped three-sided horizontal beam supports without weakening the strength of the hanging support system.
The ability to splice two or more shorter support beams into one long beam improves the storability and transportability of the entire hanging support system, permitting boxes of components to be moved and installed more easily.
Current models of ceiling storage racks for garages share some general design characteristics: they fasten to garage ceilings at 4 or 6 points with vertical risers descending to connect with four horizontal members that form a rectangular frame. The risers can be adjusted for length to match slanted rafter beams and the like.
A metal screen or wire mesh is placed over the frame to serve as the floor of the storage space. The screen is designed to support loads of a stated weight.
Fratilla teaches a ceiling attachment bracket capable of spanning standard ceiling truss separations, usually 16″ to 24″. This is done with a special angle iron fitted with two connection points. The installation process is made easier and a stronger, and a two-connection-point attachment is made with the truss. This attachment strategy increases the load capacity of the present invention over earlier designs.
Note that in the Mikich patents, the “adapters” provided are very short, and will not account for multiple-beam connection with beams that are a nonstandard distance apart. Fratilla provides significantly wider attachment brackets instead of adapters, permitting the installer to find a much more convenient attachment point for placing bolt holes closer to the center of the ceiling truss.
Fratilla also teaches a three-sided, C-shaped longitudinal beam for the support rack frame, providing substantial strength improvements over the standard two-sided angle iron
The features of this invention will be best understood from the accompanying drawings, taken in conjunction with the accompanying description.
The present invention is shown in a perspective overview in
Assembly of the invention would consist of selecting the ceiling airspace to be occupied by the storage area and assembling the necessary length of support truss from the truss members 102, using a plurality of splice panels 101 to connect a plurality of said truss members 102 in sequence. The splice panels 101 would provide attachment points for the cross beams 103, and a rectangular framework would thereby be assembled. After the framework is assembled, a metal mesh floor can be laid over the frame.
While the foregoing describes a preferred embodiment, variation on this design and equivalent designs may be resorted to in the scope and spirit of the claimed invention.
