FIELD OF THE INVENTIONThe present invention relates generally to a mounting bracket, and more particularly to a mounting bracket for securing a roof-top structure to the roof top of a building.
BACKGROUND OF THE INVENTIONIt is a common practice to mount a satellite dish antenna to the roof top of a building to provide an unobstructed view of an appropriate satellite operable with the antenna for receiving signals including audio, video and other communication signals form the satellite. The antenna must have an extremely stable base to provide constant support so the antenna can be aligned to receive the signals from the satellite. In order to hold the antenna in place to provide the desired stability, the base is permanently attached to the roof top by means of an attachment assembly that structurally penetrates the building.
A variety of roof mounting structures of satellite dish antennae has been developed. For example, it is understood that U.S. Pat. No. 4,723,128 to Gasque, Jr. discloses a roof mount for securely attaching dish antennae to roofs of houses typically supported by a plurality of spaced rafters having a two-piece frame attached to a selected portion of a roof, with one piece on top of the roof supporting the dish and its adjusting mechanism and the other piece of the frame underlying the first frame beneath the roof. A plurality of fasteners penetrates the roof and both frames and draws the frames toward each other to clamp them about the selected portion of the roof and provide steady support for the antenna. It is also understood that U.S. Pat. No. 5,456,433 to Burns et al. describe an antenna roof mounting structure comprising a substantially solid planar foundation that may be secured to a roof substrate, a substantially closed geometric superstructure affixed to and vertically raised upon the foundation, and a mast for an antenna affixed to the superstructure.
However, designs and installations of such roof mounting structures are quite complex, which is due, in part, to the requirements that must be met in order to maintain both antenna stability and the structural integrity of the building. Such installations may result in water leaks due to drilling through the roofing material into rafters for mounting the roof mounting structures. Additionally, the location of a satellite antenna is generally restricted to those locations immediately adjacent to a main roof support, or joist, so as to enable engagement of the attachment assembly therewith.
Numerous methods and devices have been developed to overcome these problems by mounting a satellite antenna to a flat roof top without penetrating same. For example, it is understood that U.S. Pat. No. 4,922,264 to Fitzgerald discloses antenna mounting apparatus especially for use in connection with satellite dishes comprises a base assembly with an antenna extending upwardly therefrom, multiple ballast means extending radially from the base assembly, outer end plates disposed respectively adjacent the end of the ballast means remote from the base assembly, an aperture formed in each ballast means, and tie rods extending respectively through the apertures and interconnecting the base assembly and the associated outer end plate. It is also understood that U.S. Pat. No. 4,649,675 to Moldovan et al. discloses an apparatus for mounting an antenna on a flat roof without penetrating the waterproof membrane of the roof. The apparatus is comprised of a rigid base having a planar lower surface adapted to overlie the flat roof, ballast means carried by the base to stabilize the base, and antenna support means connected to and extending upwardly from the base.
In these non-penetrating flat roof mount designs, the ballasting members are directly exposed to the slow destructive forces of the elements and are, therefore, susceptible to erosion and wearing away due to wind, rain, snow, and ice over extended periods of time. This problem is further exacerbated by the fact that these designs typically use concrete or cinder blocks as ballasting members, the blocks being relatively brittle and sensitive to the erosive effects of the weather. As the blocks erode, they become less and less effective as ballasting members, eventually becoming completely ineffective. On the other hand, the installations of the non-penetrating roof mount structures require the expenditure of a significant amount of time, effort, and cost.
An additional disadvantage for all current roof mount designs, non-penetrating or not, is that they cannot be easily and securely engaged with the roof top without increasing the likelihood of water leaking.
Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.
