This invention relates to mechanical anchoring devices and a system for enabling suspended overhead suspension of a framework from an I-beam or truss joist.
BACKGROUND OF THE INVENTION
As more and more materials including lawn chairs, sports equipment, recreational devices and the like accumulate in a space such as a garage, a problem is that there is insufficient space on the floor or on the walls for storage of such things in the space available. Accordingly there is a need for enhanced methods and equipment for providing supplemental storage space.
An advantage of the present invention is that is can be installed without the cost of hiring professional installers.
Another advantage of the system and method of this invention is it avoids invasive changes to existing construction; and avoids a need for pre-construction.
Moreover, time is saved by avoiding clearing stored materials from a storage space such as a garage. Also, few tools and materials are required.
Another advantage of this invention is that an installation in a garage does not interfere with overhead garage door equipment and its operation or with the garage door.
In accordance with this invention overhead storage is provided in a structure with limited floor space for storage by suspending a framework from clamps secured to the flanges of a flanged overhead beam. A preferred form of flanged overhead beam is an “I” beam with a solid web, preferably composed of steel. A suitable alternative to such a steel I-beam is an Open Web Truss Joist preferably made of steel having 4″ top and bottom flanges. Typically, the steel OWTJ is used to support roof structures with series of opened half diamond steel rails welded to and in between the flanges forming a webbing structure that spans the length of the OWTJ. Regardless of the material of which the beam is composed the beam and the flanges must have sufficient strength to support the framework. In short, the invention provides for suspending a framework from flanges suitable for supporting a clamp, which flanges are formed on the sides of an I-beam or a truss joist.
As stated above, the present invention overcomes the problem of having insufficient floor space in structures that have overhead space.
The device enables the user to create overhead space easily by suspending a mechanical framework from a beam, e.g. an I-beam or a truss joist.
The invention provides a device which is easy to install, highly versatile and eliminates requisite steps, now being used to facilitate the creation of overhead storage more specifically, garages and other related garage framing configurations.
The process/system used today is restrictive due to impeding overhead garage doors, their mechanical automatic devices and other fixed obstructions. The system of the present invention enables creation of more overhead space below a support structure.
In a garage the system of this invention increases available storage space because the installation is not impeded by overhead garage doors, the devices associated with the door or the door itself. Thus additional storage space is created which had not been available heretofore.

Preferably, each of the C-Clamps 40 is bifurcated as shown in FIGS. 1, 2, and 3A.
In FIG. 1, the framework 9 is shown suspended from the flanges 10F of the I-beam 10. Each I-beam 10 comprises a web 10W with upper and lower flanges 10F. The upper flange 10F, which is on top of the web 10W, has rims 10L/10R extending to the left and right thereof. The lower flange 10F, which is on the bottom of the web 10W, also has a left rim 10L rim and a right rim 10R. The rims 10L/10R extend to the left and right respectively of the web 10F. The framework 9 is suspended from four C-Clamps 40 affixed to the rims 10L and 10R of the lower flange 10F of the I-beam 10. Two of the C-Clamps 40 are affixed to the rims 10L/10R respectively at the proximal end 10P of the I-beam 10 and the other two clamps 40 are affixed to the rims 10L/10R respectively at the distal end 10D of the I-beam 10. In other words, the four C-Clamps 40 provide support for the framework 9 which comprises the infrastructure described below.
Preferably, the C-Clamps 40 are bifurcated as will be explained below with reference to FIGS. 2, 3A and 3B. As indicated above, the nearer end of the framework 9 is suspended at the proximal end 10P of the I-beam 10 from two of the clamps 40, which are secured to the lower flange 10F. The farther end of the framework 9 is suspended at the distal end 10 of the I-beam 10 by the other two C-Clamps 40, which are secured to the lower flange 10F at the distal end 10D. The bifurcated C-Clamps 40 are on opposite sides of the I-beam 10 and are fastened to the left and right rims 10L/10R respectively of the lower flange 10F. In particular, a proximal pair of the clamps 40 are centered above the proximal side of the framework 9 with one thereof secured to the left lower rim 10L while the other clamp is secured to the right lower rim 10R on opposite side of the web 10W of the I-beam 10.
