The present invention is generally directed toward an advanced standing seam roof panel bracket that provides for securing apparatus to a standing seam roof panel. In particular, the present invention comprises an advanced means and method for securely and removeably attaching onto a standing seam of a roof panel any safety equipment, roofing installation tooling and scaffolding, roofing repair tooling, or any other equipment that is desired to be removeably secured to the standing seam of a roof panel. More particularly, the present invention comprises (i) a Pressure Clamping Device that provides the means for removeably securing roofing equipment to the standing seam of the roof panel; and (ii) a Plank Support System that provides the means, in cooperation with the Pressure Clamping Device, for removeably securing and retaining a support platform that 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. A plurality of roofing brackets provide a means for establishing a generally horizontal configuration onto which a plank is removeably attached such that a generally horizontal plane is provided such that a worker may be supported in that generally horizontal position. 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, such as metal roof panels. The nail holes are detrimental to the standing seam roof panel substrate. A detailed description of this problem is provided in U.S. Pat. No. 4,450,935 to Gustavus issued on 29 May 1984, Column 1, lines 10-28). What is needed in the art is a roofing bracket that may be securely and removeably positioned onto the standing seam roof panels without penetrating the roof panel.
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® (a registered trademark owned by NICO Innovations Inc., Poughquag, N.Y.; and commercially available from Lincoln Equipment Associates, Inc., West Medford, Mass.). The 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 one or more ladders, the weight of such equipment is a critical feature. Another critical feature in such a device is the complexity of its use. Preferably, the roofing bracket can 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 support platform define an unsafe gap between the support platform and the roof panel such that a worker's ankle could pass through the gap, between the roof panel surface and the support platform, and result in substantial injury to the worker. In addition, tools and other equipment likewise may fall through this gap potentially injuring workers positioned lower on the roof, on a ladder, or on the ground. Moreover, the device's complexity increases its cost to manufacture and procure. Accordingly, what is needed in the art is a roofing bracket that may be easily securely and removeably positioned onto a standing seam roof panel without penetrating the roof panel.
Lastly, those skilled in the art have yet to uncover a problem with a roofing bracket that may be securely positioned onto a standing seam roof panel: determining the necessary and appropriate pressure at which the clamp should engage the standing seam to support the anticipated load on the device. Accordingly, what is needed in the art is a roofing bracket that may be easily, securely and removeably positioned onto a standing seam roof panel while providing an appropriate load-bearing means or mechanism.
It is therefore an object of the present invention to overcome the shortcomings of the prior art described above and otherwise known in the art. It also is an object of the present invention to provide an advanced standing seam roof panel bracket that engages a standing seam roof panel without penetrating the roof panel or the standing seam. It is yet another object of the present invention to provide an advanced standing seam roof panel bracket that provides for securely and removeably attaching or temporarily holding apparatus on a roof panel such as safety equipment, roofing installation tooling and scaffolding, roofing'repair tooling, or any other equipment that is desired to be safely made available on a roof panel.
It is yet another object of the present invention to provide an advanced standing seam roof panel bracket that is comparatively light-weight such that it can be installed using one hand. It is yet another object of the present invention to provide an advanced standing seam roof panel bracket that provides a means or mechanism whereby the user of such device can apply the appropriate clamping pressure and measure such pressure to ensure the safe installation of the bracket to the roof panel.
The present invention comprises an advanced apparatus that may be securely and removeably attached to a standing seam roof panel. The advanced apparatus comprises a roofing bracket designed to securely and removeably clamp onto a standing seam of a roof panel, such as the standing seam of a metal roof, without penetrating the roof panel substrate. The present invention also comprises an advanced means and method for securely and removeably attaching onto a standing seam of a roof panel any safety equipment, roofing installation tooling and scaffolding, roofing repair tooling, or any other equipment that is desired to be removeably secured to the standing seam of a roof panel. The roofing bracket is designed to be comparatively light-weight such that it can be installed using one hand. The roofing bracket of the present invention provides an advanced standing seam roof panel bracket that provides a means or mechanism whereby the user of such device can apply the appropriate clamping pressure and measure such pressure to ensure the safe installation of the bracket to the roof panel.
The roofing bracket of the present invention comprises at least one Pressure Clamping Device (“PCD”) that provides the means, for example a clamping device, for removeably securing roofing equipment to the standing seam of the roof panel without penetrating the roofing substrate. In addition, the present invention also may comprise a Plank Support System (“PSS”) that provides the means, in cooperation with the PCD, for securely and removeably clamping onto a standing seam of a roof panel and providing a substantially level platform for supporting a worker or equipment thereon.
The present invention comprises an improvement to the roofing bracket apparatus and system disclosed in U.S. Pat. No. 7,568,671 entitled Roofing Bracket Apparatus and System issued on 4 Aug. 2009 to Mario Lallier (the “Lallier patent”), which patent is incorporated herein in its entirety. The present invention comprises advancement in the design of the PCD including advanced designs for the means for angle adjustment or radial extension of the PSS. Accordingly, a greater degree of flexibility is provided such that a generally horizontal platform may be provided for a greater degree of incline of roof. The roofing bracket of the present invention also provides a means for measuring and adjusting the pressure of the clamping mechanism exerted on the standing seam thereby providing the necessary and appropriate pressure to support the anticipated load.
