BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention generally relates to the field of protecting building apertures such as door and window openings from hurricanes, wind-blown debris, gales, rain, and vandals. More specifically it concerns very low cost, low profile extrusion brackets designed specifically for installation during original building construction in combination with a variety of conventional manufactured windows, and hinged or sliding glass doors in conventional building structures, and the use of those brackets with adjustable, lightweight isosceles trapezoidal corrugated panels for protection. The goal is to render building apertures compliant with the International Building Code (“I.B.C.”) even though those building apertures employ fenestration products that are unmodified for I.B.C. compliance.  
         [0003]     2. Description of the Prior Art  
         [0004]     Investigations of damage from major hurricanes such as Hurricane Andrew indicate that most of the damage to a residence structure is from the wind and wind borne missiles that break windows and allow rain and wind into the structure. In south Florida, where Hurricane Andrew caused unprecedented destruction, nearly all residential structures are masonry, cinder block structures with wooden gable ends and roofs. Once the wind reaches the interior of such structures, the resulting pressure tends to blow out the windows, gable ends and/or lift the roof off the structure. This is due in part to the Bernoulli effect, where wind blowing around and over a building causes lower pressure than the high pressure air inside, and sucks out a window, gable end, or roof. Just as an airplane rises due to the pressure differential of faster air moving over a wing to create a low pressure, compared to the high pressure of slower moving air under a wing, so too do the weakest structures in a home tend to be blown out due to the Bernoulli effects of wind blowing around and over the building. Of course, window and door shutters of adequate design can help keep the wind and rain from entering a home during a hurricane or strong storm.  
         [0005]     Historically, upon the approach of a hurricane many homeowners have nailed plywood sheets over building apertures seeking to prevent wind-driven rain and debris from breaking into the structure&#39;s interior. Nailing sheets of plywood over every building aperture is difficult on many homes, and can take too much time to complete before the storm hits. Moreover, many homeowners are reluctant to drive nails into their window frames or do not want to be on a ladder during high winds. An individual has difficulty in holding up a large, heavy piece of plywood and nailing it in at the same time, especially as the wind velocity increases. In addition, when a hurricane approaches, building suppliers almost invariably run out of plywood.  
         [0006]     As a result of recent hurricanes making landfall and devastating numerous structures, especially as Hurricane Andrew did, many building codes were found to be inadequate to protect structures and their occupants. Multiple state and federal agencies came together with a uniform goal to standardize building methods. Specifically, the merger of the Southern Building Code Congress International (SBCCI) with both the Building Officials and Code Administrators (BOCA) and the International Conference of Building Officials (ICBO) resulted in the International Code Council (ICC). The ICC has created a series of uniform international building codes including one that applies to residential structures, which will be referred to in this document as the International Building Code (“I.B.C.”). Accordingly, reference to the I.B.C. hereinafter specifically means compliance with the hurricane protection aspects of the I.B.C. for residential structures.  
         [0007]     The first state to adopt this new I.B.C., in 2002, was Florida which was shortly followed by North Carolina. The code specifically required hurricane protection for all residential structures within a certain distance of coastal waters.  
         [0008]     The economic impact of the new code on fenestration products was the cause of the present invention. One of its prominent features is that it allows fenestration manufacturers to continue production of their products with little or no structural design changes while compliance with the I.B.C. can still be achieved. A builder who is installing a window, door or sliding glass door is required under the I.B.C. to have impact protective apparatus protecting the glazed (glass covered) building apertures. The builder or installer of the window can place the inventive brackets on the window prior to installation and then secure hurricane protection panels to the exterior side of the window without interfering or changing the design of the window. Other advantages are: consolidating products prior to installation reduces labor costs, providing a user friendly easily installed shutter, installation can be within the opening of the building&#39;s structure with masonry structures and in such instances does not extend beyond such opening, there&#39;s no need for screws or bolts, headers or sills to be fastened to the exterior surface of a building, with this combination system decorative or ornamental designs can once again be placed around the window&#39;s perimeter, and the use of the brackets actually strengthens the fenestration products.  
         [0009]     There is a great profusion of prior art in this field. Most of it relates to hurricane and storm shutters that are applied to building apertures after the building is constructed, and virtually all of it deals with the masonry structures common only to South Florida, and not the wood frame structures that predominate the entire rest of the United States.  
         [0010]     A first example is Hill, U.S. Pat. No. 5,487,244, for a shutter system with a downwardly facing channel bolted to the exterior of the structure as a header and using an angle iron sill in combination with isosceles trapezoidal corrugated panels disposed between the header and the sill to protect the building aperture. A very similar reference is Poirier, U.S. Pat. No. 6,209,263, which also employs a downwardly facing channel as a header and an angle iron sill between which are disposed isosceles trapezoidal corrugated panels. Another example is DiVeroli, U.S. Pat. No. 6,189,264, which discloses a storm shutter system capable of being installed from the interior of the structure through the building aperture and which uses an upwardly facing channel at the sill and either downwardly facing channel as a header or a bracket, in each case being attached to the exterior of the building. Other examples are Knezevich, et al., U.S. Pat. Nos. 6,021,839 and 6,122,868, which use other complex extrusions at the header and the sill which extrusions are bolted to the exterior of a structure. A further example is Thompson, et al., U.S. Pat. No. 6,205,713 which uses brackets attached to the exterior of the structure.  
         [0011]     A number of the prior art references include exterior frames and utilize louvers to cover the building aperture. Examples are Horn et al., Patent Application Publication No. U.S. 2002/0056230 A1 and Biggers, U.S. Pat. No. 6,148,895. Some of the references employ complex structures such as Mullet et al., U.S. Pat. No. 6,341,639. See, for example, the elaborate extrusions shown in  FIG. 13  thereof. Also see  FIGS. 35-39A  thereof. Another example of a reference having exceptionally complex extrusions is Fullwood, U.S. Pat. No. 5,857,298. See, for example,  FIGS. 3-5 ,  7 - 10 ,  12 - 15 ,  17 - 20 , and especially  FIG. 28 .  
         [0012]     As will be more fully seen hereinafter, the present invention includes headers and sills that are simple extrusions intended to be installed at the time of original building construction to produce in combination with isosceles trapezoidal corrugated panels a very unobtrusive, very simple, and very inexpensive hurricane shutter. While the present invention differs from the overwhelming majority of the profusion of prior art that is intended for installation after construction of the building is complete, the prior art is not devoid of references teaching storm shutters intended to be installed as part of original building construction. Examples are Fullwood, U.S. Pat. Nos. 5,857,298 and 5,941,031, and Biggers, U.S. Pat. No. 5,540,018. Biggers &#39;018 adopts the same notions of the present invention of having brackets installed with windows at the time of original building construction to save time and money and using isosceles trapezoidal corrugated panels with the brackets, but the extrusions are much more complex than those featured in the present invention, making them much more expensive, and sacrificing the goal of the present invention in which the conventional fenestration products require little or no modification to be compatible with the brackets used for the hurricane shutters. See, for example,  FIGS. 6-11 , and  13 - 17 .  
       SUMMARY OF THE INVENTION  
       [0013]     Bearing in mind the foregoing, it is a principal object of the present invention to provide a hurricane shutter apparatus for installation in a building at the time of its original construction that will result in compliance with the International Building Code (“I.B.C.”) using conventional fenestration products in combination with simple, inexpensive extrusions as header and sill brackets to support in storm conditions simple, inexpensive isosceles trapezoidal corrugated panels.  
         [0014]     It is a related principal object of the invention to enable the reduction of labor costs in constructing I.B.C. compliant structures using conventional fenestration products by combining simple, inexpensive extrusions with those conventional products prior to installation of the combinations in building apertures during original construction.  
         [0015]     Another related object of the invention is to achieve the installation of hurricane shutter supporting brackets for I.B.C. compliant structures that use conventional fenestration products without attaching those brackets using screws or bolts on the exterior surface of a building or where the brackets are exterior to the building.  
         [0016]     An additional object of the invention is to install at original building construction header and sill brackets for use with conventional fenestration products in a I.B.C. compliant building that is completely disposed within a conventionally sized building aperture such that decorative or ornamental designs can once again be placed around the window&#39;s perimeter.  
         [0017]     A further object of the invention is to provide a user friendly easily installed shutter which does not extend beyond the building aperture in the case of masonry structures.  
         [0018]     A related principal object of the invention is to employ such headers and sills that are of simple, low profile design.  
         [0019]     A further object of the invention is to provide such header and sill extrusions that accommodate both buildings constructed from masonry with conventional flange windows, and buildings constructed with wood frames having conventional fin windows.  
         [0020]     Another object of the invention is to provide a hurricane shutter apparatus that has a minimum profile designed to have the least effect on the appearance of the building and the building apertures when not in use.  
         [0021]     A further object of the invention is to provide a hurricane shutter apparatus that has been tested as a large missile impact protective system in accordance with the I.B.C. and the Florida Building Code 2001 Nonhigh Velocity Hurricane Zones, and further has been tested for Large Missile Impact Resistance in conformance with ASTM-E 1886-97, 1996-99 and for uniform load structural test ASTM E-330.  
         [0022]     Another object of the invention is the use of strong and inexpensive isosceles trapezoidal corrugated panels that are small, lightweight, and easy to install even in windy conditions, and which take up minimal storage space as the panels nest one into the other.  
         [0023]     A further object of the invention it is to utilize a header, which when installed during original building construction in a wood frame structure directs water from rain against the side of the building away from the window even when the shutter panels are not in use.  
         [0024]     An additional object of the invention is to employ header and sill extrusion designs that provide adequate spacing away from fenestration products for the installation of isosceles trapezoidal corrugated panels.  
         [0025]     One more object of the invention is to utilize a sill that employs a recessed slide bolt track that is unobtrusive and has no projecting parts to create a tripping hazard when used with a building aperture furnishing ingress and egress from the building.  
         [0026]     A further object of the invention is to provide with wood frame residential structures a rain hood or watershed with a header bracket that is embedded in the wall and that forces water away from the window to prevent leakage, mildew and rot.  
         [0027]     Another object of the invention is to strenghen fenestration products by the application of the inventive brackets.  
         [0028]     Other objects and advantages will become apparent to those skilled in the art upon reference to the following descriptions and the appended drawings.  
         [0029]     In accordance with a principal aspect of the invention there are provided two pairs of brackets for installation at the time of original building construction. The first pair are designed to be a header and sill with wood frame buildings and fin windows such are in use in most of the United States, except South Florida. As noted above, the prior art appears devoid of references that teach hurricane shutters for wood frame residential structures. The second pair are designed to be a header and sill with masonry buildings and flange windows such as are in almost unanimous usage in South Florida. In the following descriptions of the inventive brackets, the terms “inwardly” and “inside” refer to a direction toward the interior of the building on which the brackets are installed during original construction. The terms “outwardly” and “outside” refer to a direction toward the exterior of the building.  
         [0030]     The first header bracket is comprised of a downwardly facing channel having a channel web, inner channel flange and outer channel flange. The lower edge of the outer channel flange includes a flare. The channel web is co-planar with a horizontal inwardly projecting arm. Co-planar with the inwardly projecting arm inside of the inner channel flange is disposed a window element web. That terminates with a downwardly depending window element flange. The window element flange outer surface is a contact point for a first window element known as a window flange. The window element web doubles as a spacer between the window and where the corrugated panels are inserted into the downwardly facing channel. On the inside of the window element flange and co-planar with the horizontal inwardly projecting arm is a horizontal window depth spanner. The window depth spanner forms a space between the first window element and a second window element described below. At the inside edge of the window depth spanner and disposed at right angles thereto is a vertical arm. Finally, the vertical arm is at right angles to a window element ridge inside the top edge of the vertical arm. This provides for a window element recess for insertion of the second window element, a window fin, such as already exists with conventional fin windows, which are used in wood frame residential structures throughout the United States.  
         [0031]     The first sill bracket is comprised of a recessed bolt head track body containing a recessed bolt head track with a vertical track aperture, vertical track upper face, and vertical track lower face. At right angles to the top of the upper track face is a horizontal track body top. It serves as a resting point for a first window element, the window flange. The horizontal track body top also doubles as a spacer between the window and where the corrugated panels are bolted to the recessed bolt head track body. At the inside edge of the track body top and at right angles thereto is a vertical window depth spanner wall. At the top edge of the window depth spanner wall and at right angles thereto is a horizontal window depth spanner. At the inside edge of the window depth spanner is a vertical downwardly projecting arm. At the bottom of the downwardly projecting arm is an inwardly oriented window element ridge, which creates a window element recess between the downwardly projecting arm and the building structure for the insertion of a second window element, a window fin, such as already exists with conventional fin windows.  
         [0032]     The second header bracket is comprised of a downwardly facing channel having a channel web, inner channel flange and outer channel flange. The lower edge of the outer channel flange includes a flare. The channel web is co-planar with a horizontal inwardly projecting arm to interface with the building structure. On the inside of the inner channel flange and part way down the inner channel flange is a horizontal spacer web. At the inside of the spacer web is a downwardly depending window element wall. Co-planar with the spacer web and inside of the window element wall is a window element ridge. The window element ridge creates a window element recess between the building and the window element wall for the insertion of a window element, a window flange, such as already exists with conventional flange windows.  
         [0033]     The second sill bracket is comprised of a recessed bolt head track body containing a recessed bolt head track with a track aperture, track upper face, and track lower face. Co-planar with the track lower face is a horizontal inwardly projecting arm to interface with the building structure. Disposed inwardly from the bolt head track is a vertical window element receiving slot for the insertion of a window element such as already exists with conventional flange windows. The slot is formed between the recessed bolt head track body and a parallel vertical slot wall. Co-planar with the slot wall and depending vertically downwardly from beneath the horizontal plane of the inwardly projecting arm is the downwardly projecting arm. At the bottom of the downwardly projecting arm is a base member having a stucco ground ridge.  
         [0034]     In accordance with a secondary aspect of the invention, there are provided a plurality of isosceles trapezoidal corrugated panels and wingnut bolts. The panels are to be disposed between the header and sill brackets when a hurricane or other storm threatens, and bolted firmly in place using the bolt heads disposed in the recessed track of the sill bracket, the bolts&#39; shafts disposed through perforations in the lower ends of the panels, and tightened in place using the wingnuts.  
         [0035]     The panels when examined in a top or bottom view show most corrugations are conventionally sized, but with one lateral edge corrugation on each panel having a greater width than the conventionally sized corrugations. This results in the ability to laterally adjust the panels&#39; positions with respect to each other and thus adjust the width of the building aperture to be covered.  
         [0036]     In accordance with a tertiary aspect of the invention, there are provided a plurality of alternate embodiment brackets that will be described in similar terms to the foregoing in the Detailed  
       DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0037]     In accordance with a final aspect of the invention, the installation of the header bracket in a wood frame residential structure at the time of its construction leads to substantial unexpected advantages to the resistance of the structure and fin windows to conventional rain. A fin window (the type employed with wood frame residential structures) is attached the building aperture by having its fins fastened to the substrate of the wall surrounding the building aperture through a vapor barrier. The substrate is the material that is nailed to the studs that are inside every wood frame wall, the substrate frequently being plywood. The vapor barrier is applied over the substrate, and is usually polyethylene sheeting. Since the fins on a fin window are roughly half way through the thickness of the window frame, the outer half of the window frame is outside of the substrate and vapor barrier, and the channel around the outside of the frame that is outside of the substrate and vapor barrier is a candidate for the collection of rain water, even though the building&#39;s facing such as shingles, faux brick, aluminum or wood siding, etc. is applied on top of the vapor barrier. When rain water accumulates in this channel, it can access the window itself through screw holes in the window frame. But when the header bracket used with wood frame buildings is installed with the fin window, its window element ridge is pressed tightly against and sealed to the vapor barrier preventing any water from reaching the window. Sealing is accomplished using seam seal tape or the like. The downwardly facing channel web of the header bracket then forces rain water away from the top of the window, acting as a rain hood or watershed.  
         [0038]     In terms of the method of construction and installation of the header bracket and window, the wall is constructed of studs with the substrate then applied thereto. Vapor barrier is then applied over the substrate and taped into the window apertures. The header bracket is combined with the fin window and both are attached to the substrate through the vapor barrier. Both are then sealed to the vapor barrier using seam seal tape or the like. Attaching the header bracket to the substrate and then sealing prevents any water from reaching the window frame, with all water being forced away from the top of the window by the downwardly facing channel web and outer flange. In effect the header bracket is embedded into the wall to provide complete rain hood or watershed protection to the fin window. This is vitally important to prevent eventual leakage, mildew and rot.

Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.  
         [0080]     Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various figures are designated by the same reference numerals.  
         [0081]      FIG. 1  is a perspective view of a building  10  under construction having six building apertures, five windows  12 ,  14 ,  16 ,  18 , and  20 , and one hinged door  22 . Two windows  16  and  18  are ready for installation with the header  24  and sill  26  brackets in place on the windows. Two windows  12  and  14  are shown installed with the header  24  and sill  26  brackets in place. One window is shown installed with hurricane shutter panels  28  in place to protect the building aperture.  
         [0082]      FIG. 2  is an exploded perspective view of header  24  and sill  26  brackets above and below a typical window  30  with partial paneling  32  to the right side of the window. As shown by the phantom lines, the tops of panels  32  are first inserted into the header bracket  24 , then the panel bottoms, which are perforated  34  to receive threaded portions of bolts  36  are bolted to sill bracket  26  with wingnuts  38 .  
         [0083]      FIG. 3  is a perspective view of a building  40  having six building apertures, four windows  42 ,  44 ,  46 , and  48 , one hinged door  50  and one sliding glass door  52 , all of which are covered with the inventive hurricane shutter apparatus. All the building apertures are protected by the preferred embodiment of a header  24  and a sill  26  bracket equipped with vertically disposed isosceles trapezoidal corrugated panels. The sliding glass door  52  is protected with alternative embodiment vertical brackets  54  with horizontal hurricane protection storm panels  56 . The vertical brackets  54  are similar to two sill brackets which have bolts to hold the horizontal panels  56  in place as better seen in  FIG. 4 . The hinged door  50  uses an alternative embodiment exterior wall mounted header  24  and sill  26  supporting the isosceles trapezoidal corrugated panels  32 .  
         [0084]      FIG. 4  is an exploded perspective view of a typical sliding glass door  58  with vertical brackets to be attached to the sliding glass door jambs  60 , with partial paneling  56  beneath the sliding glass door  58 . As shown by the phantom lines, the sides of panels  56  which are perforated  62  to receive threaded portions of bolts  64  are bolted to vertical brackets  54  with wingnuts  66 .  
         [0085]      FIG. 5  is a perspective view of a first header bracket  112  comprised of a downwardly facing channel  114  having a channel web  116 , inner channel flange  118  and outer channel flange  120 . The lower edge of the outer channel flange includes a flare  122 . The channel web  116  is co-planar with a horizontal inwardly projecting arm  124 . Co-planar with the inwardly projecting arm  124  inside of the inner channel flange  118  is disposed a window element web  126 . That terminates with a downwardly depending window element flange  128 . The window element flange outer surface  129  is a contact point for a first window element known as a window flange as will be seen in  FIG. 8 . The window element web  126  doubles as a spacer between the window and where the corrugated panels are inserted into the downwardly facing channel  114 . On the inside of the window element flange  128  and co-planar with the horizontal inwardly projecting arm  124  is a window depth spanner  130 . The window depth spanner  130  forms a space between the first window element and a second window element described below. At the inside edge of the window depth spanner  130  and disposed at right angles thereto is a vertical arm  134 . Finally, the vertical arm  134  is at right angles to a window element ridge  136  inside the top edge  138  of the vertical arm  134 . This provides for a window element recess  140  for insertion of the second window element, a window fin such as already exists with conventional fin windows as will be seen in  FIGS. 7 and 8 .  
         [0086]      FIG. 6  is a perspective view of a first sill bracket  141  comprised of a recessed bolt head track body  142  containing a recessed bolt head track  144  with a vertical track aperture  146 , vertical track upper face  148 , and vertical track lower face  150 . At right angles to the top of the track upper face  148  is a horizontal track body top  152 . It serves as a resting point for a first window element, the window flange, as will be seen in  FIG. 8 . The horizontal track body top  152  also doubles as a spacer between the window and where the corrugated panels are bolted to the recessed bolt head track body  142 . At the inside edge of the track body top  152  and at right angles thereto is a vertical window depth spanner wall  154 . At the top edge of the vertical window depth spanner wall  154  and at right angles thereto is a horizontal window depth spanner  156 . At the inside edge  158  of the window depth spanner  156  is a vertical downwardly projecting arm  160 . At the bottom of the downwardly projecting arm  160  is an inwardly oriented window element ridge  162 , which creates a window element recess  164  between the downwardly projecting arm  160  and the building structure for the insertion of a second window element, a window fin, such as already exists with conventional fin windows.  
         [0087]      FIG. 7  is an exploded view of the header bracket  112  of  FIG. 5  and sill bracket  141  of  FIG. 6  with a conventional fin window  520  and with a hurricane shutter panel  522  in proximity to its installation position and with a typical bolt  524  and wingnut  526  used to secure the panel upon installation to the sill bracket  141 . Fin window  520  includes a first window feature, window flanges  528  and  530 , and second window feature, window fins  532  and  534 .  
         [0088]      FIG. 8  is an assembly drawing showing the elements of  FIG. 37  completely assembled on a wood frame building  536 . Header bracket  112  is shown assembled with fin window  520  to wood frame building  536  using wood screw  538 . Wood screw  538  passes through vertical arm  134  of header bracket  112  first, then through window fin  532  before reaching the wood of building  536 . Note that window element ridge  136  creates a window element recess  140  for window fin  532 . Also note that window element flange  128  provides a contact point for window flange  528 . Further note that window element web  126  provides a spacer  540  between window  520  and where corrugated panels  522  are inserted into downwardly facing channel  114 . Finally note that window depth spanner  130  forms a space between first window element, window flange  528 , and second window element, window fin  532 . All of these spacing considerations make header bracket  112  completely compatible with conventional fin window  520  and show that the bracket  112  can be readily assembled with conventional fin window  520  when the latter is first placed in a wood frame building aperture at the time of construction.  
         [0089]     The same is true for sill bracket  141 . Wood screw  538  passes first through vertical downwardly projecting arm  160  of sill bracket  141  and then through window fin  534  before reaching wood frame building  536 . Also window element ridge  162  creates window element recess  164  to accommodate window fin  534 . Also note that window flange  530  rests on horizontal track body top  152  and that horizontal track body top  152  also doubles as a spacer  540  between the window  520  and the corrugated panels  522  bolted to the recessed bolt head track body  142 . Note that horizontal window depth spanner  156  establishes the proper distance between window flange  530  and window fin  534 . So the sill bracket  141  meshes perfectly with conventional fin window  520 . Hurricane shutter panels  522  are firmly attached to sill bracket  114  using bolts  524  and wingnuts  526 .  
         [0090]      FIG. 9  is an exploded bottom view of a sill bracket  542  and hurricane protection storm panels  522  in proximity thereto. A plurality of bolts  524  are slidingly installed in a track of bottom sill  542  as seen in  FIG. 8 . The fact that they can slide laterally is illustrated by up and down arrows intercepting the threaded portion of each bolt  524 . Hurricane panels  522 , described early in this application as adjustable, lightweight isosceles trapezoidal corrugated panels, are attached to bolts  524  using wingnuts  522  shown in exploded proximal alignment to each other. Each panel  522  includes several conventionally sized isosceles trapezoidal corrugations  544 ,  546 ,  548 , and  550  followed by a wider than usual isosceles trapezoidal corrugation  552 . Overlapping the wide corrugation  552  is a conventionally sized corrugation  544 ′. As  FIG. 9  shows, this means that panels can be adjusted laterally with respect to each other because the conventionally sized corrugation  544  can be slid one way or the other within the wide corrugation  552 .  
         [0091]      FIG. 9A  is a broken back elevation view of the bottom edge of a single hurricane protection storm panel  522 . Each of the alternating corrugations that come in contact with sill bracket  542 , such as corrugations  544  and  548 , include perforations  554  and  556  to accommodate the threaded portions of bolts  524 . But for wide corrugation  552  there is instead provided a slot  558  to accommodate the adjustment function with regard to the adjoining panel having a first corrugation  544 ′. This adjustment feature is obviously to accommodate different building aperture widths.  
         [0092]      FIG. 10  is a perspective view of a second header bracket  68  comprised of a downwardly facing channel  70  having a channel web  72 , inner channel flange  74  and outer channel flange  76 . The lower edge of the outer channel flange includes a flare  78 . The channel web  72  is co-planar with a horizontal inwardly projecting arm  80  to interface with the building structure. On the inside of the inner channel flange  74  and part way down the inner channel flange  74  is a horizontal spacer web  82 . At the inside of the spacer web is a downwardly depending window element wall  84 . Inner channel flange  74 , spacer web  82  and downwardly depending window element wall  84  together form a space between the window and where the corrugated panels are inserted into the downwardly facing channel  70 . Co-planar with the spacer web  82  and inside of the window element wall  84  is a window element ridge  86 . The window element ridge creates a window element recess  88  between the building and the window element wall  84  for the insertion of a window element, a window flange, such as already exists with conventional flange windows.  
         [0093]      FIG. 11  is an exploded perspective view of a second sill bracket  89  comprised of a recessed bolt head track body  90  containing a recessed bolt head track  92  with a track aperture  94 , track upper face  96 , and track lower face  98 . Co-planar with the track lower face  98  is a horizontal inwardly projecting arm  100  to interface with the building structure. Disposed inwardly from the bolt head track  92  is a vertical window element receiving slot  102  for the insertion of a window element, a window flange, such as already exists with conventional flange windows. The slot  102  is formed between the recessed bolt head track body  90  and a parallel vertical slot wall  104 . Recessed bolt head track body top  105  is of a width sufficient to provide a spacer between the window and where the corrugated panels are bolted to the recessed bolt head track body  90 . Co-planar with the slot wall  104  and depending vertically downwardly from beneath the horizontal plane of the inwardly projecting arm  100  is the downwardly projecting arm  106 . At the lower end of downwardly projecting arm  106  is base member  108 , on which is disposed stucco ground ridge  110 .  
         [0094]      FIG. 12  is an exploded view of the header bracket  68  of  FIG. 20  and the sill bracket  89  of  FIG. 21  with a conventional flange window  560  and with a hurricane shutter panel  522  in proximity to its installation position and with a typical bolt  524  and wingnut  526  used to secure the panel upon installation to the sill bracket  89 . Flange window  560  includes window features, termed window flanges  562  and  564 .  
         [0095]      FIG. 13  is an assembly drawing showing the elements of  FIG. 40  completely assembled in a masonry building  566 . Conventional flange window  560  is shown installed in the masonry building  566  aperture between portions of wood buck  568  and  570 . The opening seen between masonry  566  and wood buck  570  is for shimming and caulking (not shown). The header bracket  68  is shown attached to masonry  566  through its horizontal inwardly projecting arm  80  using threaded masonry anchor  572  which passes first through wood buck  568  and then horizontal inwardly projecting arm  80 . Sill bracket  89  is shown attached to masonry building  566  indirectly. First, threaded masonry anchor  574  secures wood buck  570  to masonry building  566 . Second, sill bracket  89  is attached to wood buck  570  using wood screw  578  which passes through downwardly projecting arm  106  of sill bracket  89 . Flange window  560  is held in position at its top by the retention of window flange  562  by a window element recess  88  formed by window element ridge  86 . Conventional flange window  560  is held in position at its bottom by window flange  564  being retained in vertical window element receiving slot  102  in sill bracket  89 . Spacer web  82  in header bracket  68  provides a space  576  between flange window  560  and where corrugated panels  522  are placed in downwardly facing channel  70  in header bracket  68 . Similarly, recessed bolt head track body top  105  provides a space  576  between flange window  560  and where corrugated panels  522  are bolted to recessed bolt head track body  90 .  
         [0096]      FIG. 14  is an exploded perspective view of an alternative embodiment sill bracket  166  for use with a sliding or roller window, but it lacks the recessed bolt head track of the first and second sill brackets. It includes a horizontal flat track  168  at its top to interface with the frame of the window, from the outside edge of which depends downwardly a vertical member  170 . The vertical member  170  is perforated by one of a plurality of bolts  172  pointing horizontally outward threaded through the vertical member  170 . These receive wingnuts  174 , one of which is shown in axial proximity to the bolt  172 . The nuts  174  and bolts  172  attach isosceles trapezoidal panels to the third sill bracket  166 .

This is done by passing the bolts  498  through perforations  502  in the hurricane protection panels  500  and applying wingnuts  504  to the bolts  498 . In  FIG. 35 , the slide bolt recessed track bodies  506  are applied to the exterior of a conventional door  492 .  
         [0118]      FIG. 36  is an exploded perspective view of a cross section of the lower portion  508  of a more improved door with a slide bolt track channel  510  that is recessed within the door for holding the head of a bolt  512  that provides the means for attaching the lower portion of hurricane protection panels  500  (as shown in  FIG. 35 ) to a door using a wingnut  514 . When inverted, the same structure operated to attach the top portions of the panels  500  to the top of the door. Because the slide bolt track channel  510  is recessed within the door, access by the bolt  512  heads to the track  510  must be had through relief notch  516 .  
         [0119]      FIG. 37  is an exploded cross section view of a pair of add on recessed bolt head track door J-brackets  580  with a pre-existing particle wood door  582  in proximity to hurricane protection shutter panels  522 . The J-brackets  580  add recessed bolt head track bodies  584  containing recessed bolt head tracks  586  to the top and bottom of the door  582  for retaining bolt heads  524 , to which are then applied the shutter panels  522  and wingnuts  526 .  
         [0120]     Turning finally to  FIG. 38 , an assembly drawing showing add on recessed bolt head track door J-brackets  580  applied respectively to the top and bottom of wood particle door  582 , to which has been applied hurricane protection shutters  522  using bolts  524  and wingnuts  526 . The door  582  with J-brackets  580  and panels  522  is installed in a masonry building  588  with wood buck  590 , conventional door sill  592 , and interior molding  594  held by threaded masonry anchors  596 . The top mates with conventional wood frame header  598 . The periphery of the door  582  is surrounded by resilient compressible weather stripping  600 . One significant advantage of these add on recessed bolt head track door J-brackets  580  is that they allow the application of hurricane protection shutter panels  522  to a pre-existing door with little or no modification thereto and without interfering with the door&#39;s ingress and egress functions when the shutters  522  are deployed for storm protection. Additionally, if the door contains any glazing, the glazing is covered and protected. Finally, the door is strengthened by the application of the J-brackets  580  whether or not the hurricane protection panels  522  are deployed thereon.  
         [0121]     While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.

Summary:
Disclosed is storm shutter apparatus for protecting building apertures such as door and window openings from hurricanes, wind-blown debris, gales, rain, and vandals using very low cost, low profile extrusion brackets designed specifically for installation during original building construction in combination with a variety of conventional manufactured windows, hinged doors or sliding glass doors in conventional building structures, and the use of those brackets with very low cost adjustable, lightweight isosceles trapezoidal corrugated panels. The first objective is to render building apertures compliant with the International Building Code (“I.B.C.”) even though they are constructed with conventional fenestration products unmodified for I.B.C. compliance. Another objective is to accomplish the foregoing without the expense of separate labor costs for the installation of hurricane shutters and without the expense of purchasing fenestration products modified for I.B.C. compliance.
