     FIELD OF THE INVENTION 
     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. 
     BACKGROUND OF THE INVENTION 
     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&#39;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&#39;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&#39;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. 
     SUMMARY OF THE INVENTION 
     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.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     A three-dimensional illustration of a preferred embodiment of the invention ( 10 ) is shown in  FIG. 1 . The present invention comprises a base ( 12 ) having a top face and a bottom face, the base ( 12 ) bottom face designed to be positioned upon a roof panel and proximate to a standing seam of the roof panel. A conventional pad ( 14 ) fabricated from rubber or other suitably malleable material is positioned on the bottom face of the base ( 12  to protect the finish of the roof panel and standing seam. 
     Preferably, pad ( 14 ) is comprised of UV resistant EPDM rubber and the pad is fabricated by an injection molding process. In addition, the pad preferably defines a slight vertical or inclined groove to permit rain water or other precipitation to flow therethrough. The base ( 12 ) and pad ( 14 ) may be joined by any conventional means suited for the materials that comprise the base ( 12 ) and pad ( 14 ), such as for example a conventional adhesive means for joining an aluminum base to a rubber pad. Preferably, the pad is joined to the base with adhesive and conventional fasteners such as rivets  92 . 
     Roofing bracket ( 10 ) is removeably secured to an inclined roof panel whereby the roofing bracket ( 10 ) preferably is positioned on a standing seam of a roof panel. Roofing bracket ( 10 ) defines a first section ( 16 ) and one or more second section(s) ( 18 ). First section ( 16 ) and second section(s) ( 18 ) are positioned adjacent to and on opposite sides of a standing seam of a roofing panel. First section ( 16 ) and second section ( 18 ) may be fabricated from a variety of materials known in the art such as, for example, steel, aluminum, wood, or synthetic materials. 
     The base ( 12 ) of first section ( 16 ) supports at least one PCD subframe ( 20 ) that, in turn, supports a PCD ( 22 ). In  FIG. 1 , PCD ( 22 ) is shown in an unlocked position; and in  FIG. 2 , PCD ( 22 ) is shown in a locked position. The base ( 12 ) of first section ( 16 ), if desired, also supports a PSS ( 24 ). In  FIG. 1 , PSS ( 24 ) is shown in an elevated position. In combination, a method for providing a substantially level working platform according to the present invention comprises at least two standing seam roofing brackets ( 10 ). Each roofing bracket ( 10 ) comprises at least one and preferably two PCD&#39;s ( 22 ) and one PSS ( 24 ). A substantially horizontal platform is provided by positioning a plank, comprised of standard robust construction material, between at least two roofing brackets ( 10 ). The plank is positioned on each respective main plank bracket ( 28 ) of each roofing bracket ( 10 ). The PSS ( 24 ) also comprises one of a variety of supporting plank brackets ( 26 ). Preferably, the plank is secured to a PSS ( 24 ) by any conventional fastening means which may be passed through aperture ( 32 ) in main plank bracket ( 28 ) and aperture ( 30 ) in supporting plank bracket ( 26 ). Such a conventional fastening means for securing the plank to the plank brackets may comprise, for example, standard fasteners. Preferably, the securing means comprises a plurality of screws or the like. 
     In one embodiment of the present invention, the plank comprises a hardwood 2 in.×12 in. plank of sufficient length to span standard standing seams. Alternatively, a hardwood 2 in.×8 in. or 2 in.×10 in. plank of sufficient length may be used. The selected plank would be securely positioned within a respective PSS ( 24 ) by positioning the plank onto each respective main plank bracket ( 28 ) of each roofing bracket ( 10 ). The platform would further be secured to the PSS ( 24 ) by selecting an appropriate supporting plank bracket ( 26 ) secured to the elevated end of the PSS ( 24 ). 
     An alternative bracket configuration is shown in  FIG. 5 . The method for providing a substantially level working platform according to the present invention also comprises at least two standing seam roofing brackets ( 10 ). Each roofing bracket ( 10 ) comprises at least one and preferably two PCD&#39;s ( 22 ) and one PSS ( 24 ). The plank may be comprised of steel, aluminum, or any other suitably rigid substance. Typically, such a platform comprises less thickness than a hardwood plank. In addition, such a platform may comprise a width of up to 12 in., 14 in., 16 in., or even 24 in. or more. The alternative main support bracket ( 34 ) is sized to engage and retain a plank of less width than a hardwood plank such as for example a metal plank. The method for engaging and retaining the metal plank also includes selecting one of a variety of supporting plank brackets ( 36 ) removeably fastened to bracket ( 38 ) by any conventional means including conventional fasteners ( 40 ) such as bolts and nuts and the like. 
     Roofing bracket ( 10 ) is depicted in  FIG. 5  in an unlocked position. Alternatively, roofing bracket ( 10 ) depicted in  FIG. 5  in an unlocked position is depicted in  FIG. 6  in a locked position. 
     As further shown in  FIG. 1 , PSS ( 24 ) comprises a radial extension element ( 42 ) for elevating PSS ( 24 ) for providing a substantially level working surface. As best shown in  FIG. 5 , one embodiment of a radial extension element ( 42 ) comprises a screw lift mechanism ( 48 ) having an angle adjustment screw ( 50 ) and a handle ( 52 ) that in cooperation provide for angular rotation of the PSS ( 24 ). A prior art angle adjustment screw is commercially known as a “screw jack” and is described in the Lallier patent, FIG. 4 and Col. 3, lines 52-57. Rotation of the screw of the prior art device will cause the extension elements to rotate about pivot joints and correspondingly move the PSS away from the base (increase the angle of rotation) or toward the base (decrease the angle of rotation). One drawback with the screw jack is that rotation of the screw actuates a number of pivoting elements Such pivoting elements are not sufficiently robust to support increased loads that typically may be placed onto the platform supported by the prior art screw jack. 
       FIG. 3  provides an illustration of a PSS ( 24 ) that has been disassembled from roofing bracket ( 10 ). The PCD&#39;s ( 22 ) are shown in a locked position. PSS ( 24 ) further comprises PSS subframe ( 54 ). The top face ( 56 ) of PSS subframe ( 54 ) provides the surface onto which a plank may be placed and subsequently secured to brackets ( 26 ) and ( 28 ). Correspondingly,  FIG. 7  provides an illustration of PSS ( 24 ), disassembled from roofing bracket ( 10 ), wherein PCD&#39;s ( 22 ) are shown in a locked position and the device comprises alternative main support bracket ( 34 ), supporting plank bracket ( 36 ) removeably fastened to bracket ( 38 ), and conventional fasteners ( 40 ). 
     As further shown in  FIG. 3 , radial extension element ( 42 ) comprises screw lift mechanism ( 48 ) which, in turn, comprises angle adjustment screw ( 50 ) and handle ( 52 ). These components in cooperation provide for angular rotation of PSS subframe ( 54 ). PSS ( 24 ) further comprises adjustable subsupport ( 58 ) and PSS lower base ( 60 ). PSS lower base ( 60 ) defines mounting tabs extending upward from each side of PSS lower base ( 60 ) that provide apertures to serve as pivot joints ( 62 ). The upper end of adjustable subsupport ( 58 ) is pivotally connected to PSS subframe ( 54 ) by conventional means or fasteners that provide for rotation of adjustable subsupport ( 58 ) and PSS subframe ( 54 ) about such means or fasteners. 
     The lower end of adjustable subsupport ( 58 ) is pivotally connected to pivot joints ( 62 ) by conventional means or fasteners, such as pin assembly ( 64 ) that provide for rotation of adjustable subsupport ( 58 ) about PSS lower base ( 60 ). Lastly, the lower end of PSS subframe ( 54 ), when PSS ( 24 ) is placed in an elevated position, is pivotally connected to pivot joints ( 62 ) by conventional means or fasteners, such as pin assembly ( 64 ) that provide for rotation of adjustable subsupport ( 58 ) about PSS lower base ( 60 ). 
     Rotation of handle ( 52 ) correspondingly rotates angle adjustment screw ( 50 ) whereby adjustable subsupport ( 58 ) correspondingly elevates or lowers PSS subframe ( 54 ). Concurrently, PSS subframe ( 54 ) and adjustable subsupport ( 58 ) correspondingly rotate about PSS lower base ( 60 ) thereby supporting the elevating or lowering of PSS subframe ( 54 ). 
       FIG. 4  shows PCD ( 22 ) in a disassembled condition. Lever handle assembly ( 70 ) comprises gripping element ( 68 ), a pair of lever handle brackets ( 72 ), and lever handle bracket support ( 82 ) to engage and retain gripping element ( 68 ) within lever handle assembly ( 70 ). Lever handle assembly ( 70 ) further comprises lever handle assembly support ( 74 ), lever handle assembly bracket ( 76 ), and fastening means ( 78 ) such as one or more threaded pins and corresponding locknuts. In addition, lever handle assembly ( 70 ) further comprises PCD subframe base ( 80 ), locking bracket ( 84 ) and pivot elements ( 86 ). Correspondingly,  FIG. 8  provides an illustration of PCD ( 22 ) of  FIG. 5  disassembled from roofing bracket ( 10 ). 
     In use, lever assembly support ( 74 ) aligns with lever handle assembly bracket ( 76 ) that is mounted onto subframe base ( 80 ) by fastening means ( 78 ) such as for example one or more threaded pins and corresponding locknuts. Lever handle assembly ( 70 ) and pivot elements ( 86 ) extend over lever handle assembly bracket ( 76 ) such that apertures and pivot elements in the lever handle assembly ( 70 ) align with a corresponding subframe slot. PCD  22  further comprises a left pivot element ( 86 ), a center pivot element ( 86 ), and a right pivot element ( 86 ) wherein each pivot element ( 86 ) engages a corresponding subframe base slot. 
     The lever handle assembly, pivot elements and corresponding subframe base slot are designed such that by pressing the gripping element toward the base, the center pivot element pivots lower than the left and right pivot elements thereby locking the lever handle assembly into place. The lever handle assembly bracket and the locking bracket also engage a corresponding subframe base slot as an additional locking mechanism. By pressing the gripping element toward the base and locking it into place, the roofing bracket is pressed tightly against the standing seam of the roof panel and locked into place. 
     As further illustrated in  FIG. 4 , tags or labels ( 66 ) or the like may be applied to roofing bracket ( 10 ) thereby providing manufacturing information, instructions for use, or any other suitable information. 
     One preferable embodiment of roofing bracket ( 10 ) comprises ring bracket ( 44 ). Preferably, ring bracket ( 44 ) is removeably and securely mounted onto lever handle assembly ( 70 ). Ring bracket ( 44 ) provides a means for removeably and securely attaching a lifeline or other safety equipment, a port for temporary roofing guardrail, a holding mechanism for an upright support, roofing installation or repair tooling, or any other equipment that is desired to be removeably secured to the standing seam of a roof panel. 
     Continuing with  FIG. 4 , roofing bracket ( 10 ) preferably comprises a clamping adjustment screw ( 46 ) for each clamping device positioned upon second section ( 18 ). Clamping adjustment screw ( 46 ) provides for variability in the thickness of a roof panel standing seam. As further shown in  FIG. 4 , clamping adjustment screw ( 46 ) engages a clamping adjustment screw receiving aperture ( 88 ) defined within subframe base ( 80 ) positioned on second section ( 18 ). 
     Additionally, clamping adjustment screw ( 46 ) provides for adjusting the pressure of the clamping mechanism exerted on the standing seam thereby providing the necessary and appropriate pressure to support the anticipated load. Roofing bracket ( 10 ) is placed upon a standing seam roof panel such that the first section ( 16 ) and the second section ( 18 ) straddle a standing seam. First section ( 16 ) and second section ( 18 ) are clamped loosely on the standing seam panel and each clamping adjustment screw ( 46 ) is tightened until each respective pad ( 14 ) is snug against the standing seam. Lastly, roofing bracket ( 10 ) is disengaged and each clamping adjustment screw ( 46 ) is tightened making two complete clockwise turns of each clamping adjustment screw ( 46 ). 
     Roofing bracket ( 10 ) is reinstalled on the standing seam. Preferably, the torque applied should be in the range between about 20 and about 50 lbs. of torque per square foot; and even more preferably, between about 30 and about 35 lbs. of torque per square foot. Roofing bracket ( 10 ) uniquely comprises a method for measuring such torque. 
     The preferred process for measuring torque requires a ⅜ inch Allen socket placed onto a torque wrench. Roofing bracket ( 10 ) is disengaged and securely retained on the standing seam. As best shown in  FIG. 4 , lever handle assembly ( 70 ) defines aperture ( 90 ) positioned proximate to base  12 . Preferably, aperture ( 90 ) defines a hexagonal perimeter or a configuration in the shape of the Allen socket. The Allen socket is placed in aperture ( 90 ) and the torque wrench is applied to the Allen socket thereby measuring the torque per square foot. This process should be repeated until the torque per square foot measures within the target range. 
     Another preferred embodiment of the present invention is depicted in  FIG. 9 . Like reference characters (plus 100) will be used for corresponding features and the embodiment depicted in  FIG. 9  is referred to herein as a “PCD Bracket”.
