The present invention is generally directed toward an improved apparatus and system for enabling a worker to perform work on an inclined roof. More particularly, this invention provides an effective and efficient mechanism which may be securely and removeably attached to a standing seam roof panel and which is capable of supporting a worker thereon.
Roofing brackets designed for positioning a platform and supporting a worker thereon are well known in the art of roofing. Typically, a roof is inclined such that a worker cannot safely perform work while standing or maneuvering on the inclined plane of the roof. As is known in the art, roofing brackets are secured to a roof and a platform is positioned and retained in place. The platform provides a generally horizontal plane on which a worker may be supported. After a particular section of roofing has been installed, the roofing brackets are removed and repositioned to enable the worker to safely reach another section of the roof.
One significant problem with the roofing brackets known in the art, particularly when installing standing seam roof panels, for example a metal roof, is that the roofing brackets are fastened to the roof using nails driven into the roof structure. Examples of conventional roofing brackets are disclosed in U.S. Pat. No. 6,698,702 to Macri. Both the prior art devices and the invention disclosed therein define features referred to as “nail slots.” The use of nail slots permits the roofing bracket to be removeably secured to the roof structure. Typically, the roofing bracket is struck with a hammer to disengage the nail slots from the nails driven into the roof structure.
As is known in the art, the use of nails to temporarily fasten a roofing bracket to the underlying roof structure is incompatible with the installation of standing seam roof panels. The nail holes are detrimental to the standing seam roof panel substrate. What is needed in the art is a roofing bracket that may be securely and removeably positioned on standing seam roof panels.
One example of a device that recognizes this problem with the prior art devices provides a complex and correspondingly problematic alternative. The device is commercially known as the Brucie Bracket and is commercially available from Lincoln Equipment Associates, Inc., located in West Medford, Mass. The prior art device employs an intricate array of welded members and other structural components. The problems with this device known to those skilled in the art render this device difficult to use.
When maneuvering equipment on a roof, and up and down a series of ladders, the weight of such equipment is a critical feature. Another critical feature in such a device is the complexity of its use; preferably, it may be installed with one hand. The prior art device known as the Brucie Bracket weighs approximately 34 pounds and requires two hands to position and securely attach to a standing seam. In addition, the complexity of the device and the ultimate positioning of the platform defines an unsafe gap between the platform and the roof panel such that a worker's ankle could pass through the gap and result in substantial injury to the worker. Moreover, the device's complexity increases its cost to manufacture and procure.
Accordingly, there is a need in the art for an improved roofing bracket to provide a level working surface from which worker may install a standing seam roof panel.
The present invention provides an improved apparatus for enabling a worker to effectively and efficiently perform work on an inclined roof comprising standing seam roof panels. The present invention provides a comparatively lightweight and simple roofing bracket that may be securely and removeably attached to a metal roof. The present invention also provides a greater degree of flexibility such that a generally horizontal platform may be provided for a greater degree of incline of roof.
A preferred embodiment of the present invention is shown in
As shown in
First section 18 and a second section 20 are capable of supporting at least one, preferably two, and potentially more than two, clamping mechanisms such that upright 26 of first section 18 and upright 32 of second section 20 may be securely and removeably fastened juxtaposed to one another abutting opposite sides of standing seam 14. The clamping mechanism may comprise any number of clamping mechanisms known in the art such as conventional vise grips 36 and 38. The clamping mechanism is secured to first section 18 and a second section 20 by any conventional means, such as, for example, welding.

In another embodiment of the invention and as shown in
While the present invention has been described in considerable detail, other configurations exhibiting the characteristics taught herein for providing a comparatively lightweight and simple roofing bracket that may be securely and removeably attached to a metal roof are contemplated. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the spirit and scope of the invention should not be limited to the description of the preferred embodiments described herein.
