Description:
PRIORITY CLAIM 
       [0001]    This application claims priority to U.S. Provisional Patent Application No. 60/779,225 filed on 03 Mar. 2006 by the common inventor James D. Claywell and is further incorporated herein for all purposes. 
     
    
     BACKGROUND 
       [0002]    The present invention relates generally to devices and systems adapted to provide supplemental protection to structures such as houses, mobile-homes, commercial buildings and the like. More specifically, the present invention relates to a wind blocking or re-directing device and system for buildings. 
         [0003]    High winds exert tremendous strain on structures. Both sustained winds and the more common undulating winds conspire to weaken buildings and structures such as the walls and roofs of houses, mobile-homes, and commercial buildings. Over time, or under extreme wind conditions, catastrophic failure is induced. During a hurricane, such as the recent Hurricane Katrina experienced along the gulf-coast of the United States in 2005, fierce winds devastated structures large and small. On the windward side of a structure during high-wind conditions, the vertical walls of the structure receive massive lateral forces. These vertical walls, designed for vertical loads, often fail under such extreme conditions. Further exasperating the situation, a pressure difference builds, the exterior, windward side of the vertical wall has a relative effective high atmospheric pressure, where as the interior side, leeward of the wind has a relative effective low atmospheric pressure. This causes a great imbalance in forces, resulting in collapse. 
         [0004]    In addition, as high-winds collide with the vertical walls, some of the air-flow is directed around the structure, some air-flow finds voids that lead inside the structure, but the bulk of the flow is directed upward toward the roof. Eaves or overhangs, typical to roofs to provide sun-shade and protect the walls from moisture penetration from rain, serve as unwitting air-traps for this upward directed high-flow of displaced air. Consequently, the roof acts as a giant airfoil and is ripped from the vertical walls. 
         [0005]    Traditional approaches to mitigate the destructive force of high winds focus on adding additional structural supports to the connecting points between walls, roof, and foundation. These methods require integration during the building phase, and therefore offer limited solution for existing buildings. Other methods include a supplemental system of ground anchors, external supports, and external strapping material—and although these systems can be used on existing structures—however, these approaches are not without inherent undesirable limitations including being difficult to install during the on-set of severe wind, cumbersome to manipulate, require storage space when not in use, and are costly to produce and install, for example. 
         [0006]    In sum, the many prior-art systems, teachings, and devices attempt to augment the structural strength of the buildings. These methods, however, have not addressed diverting or redirecting the force of the wind. Therefore, there remains a need for a system and method that enhances structural integrity of buildings during high-wind conditions, while at the same time redirect the destructive force of the wind. 
         [0007]    Flying debris, another damage-causing component of high-wind storms, poses a particular challenge to home-owners and business-owners because many of the prior-art systems fail to fully address the needs of a rapidly deployable, rigid, economical, light-weight, and strong system that provides sufficient protection. For example, U.S. Pat. No. 5,613,543 to Walton and U.S. Pat. No. 6,341,455 to Gunn along with Published Application Number US 2005/0279465 by Gower (all of which are incorporated by reference for all purposes) provide examples of these approaches. 
         [0008]    Finally, current systems do not adequately secure the dwelling or structure from looting. Even if a structure or dwelling is adequately protected from the destructive brute-strength of high-velocity winds and is protected from flying debris, current systems do not provide means for securing the structure or dwelling from looting. The most common rigid-panel system comprises a 4-foot by 8-foot sheet of plywood or similar material, which is coupled to the dwelling or structure by a screw-type fastener having a common single slot or cross-slot head. Moreover, this system, further, is undesirable because it introduces numerous penetration points into the envelope of the structure that may accelerate deterioration of the structure in the long-term due to moisture penetration. 
         [0009]    More recently, an attempt to protect structures from the wind includes U.S. Pat. No. 6,088,975 titled “Hurricane Protection for Mobile Homes and Small Buildings”. This reference, issued to Wiegel on 18 Jul. 2000, presents a solution to prior art and traditional reinforcement methods of extra nails, stiffener boards, metal straps, storm shutters, shatter resistant windows, and foundation bolts. This reference presents a system to protect a structure from wind buffeting using a system comprising an in-ground channel about the perimeter of a structure, a storm-shield of rip-stop material with tie-down cables extending from a roof edge to the perimeter ground channel. This reference combines the advantages of cable-tie down systems of the prior art with wind-shielding elements to divert airflow, blocking wind from the ground and re-directing it over the house. However, this reference requires a permanent in-ground perimeter channel and complex tie-down mechanisms and fasteners to affect wind protection. Moreover, when not in use, the system is rolled up and left under the awnings of the roof. Further, the system is temporary in nature, as it would be impractical for normal use of the structure. 
         [0010]    Therefore, there remains a need for a system, method, and a device that enables either enables rapid deployment on a temporary basis, or can be integrated in new construction or retrofitted on existing structures as a lasting solution to divert wind. Such a device and system should be easy to install, be compact to store, and be economical to produce. The new system, method, and devices, further, should reduce or eliminate un-sealed penetration of the exterior skin of the dwelling or structure. Such a system, ideally, would further include locking means to thwart looters from removing the protection device. Moreover, there remains a need for a system and method that enables normal use of the structure with little or no modification to the protection system as it transitions from non-use to use in protecting the structure from winds, debris, or both. 
       SUMMARY OF THE INVENTION 
       [0011]    In one embodiment, the present invention comprises a system and method for providing enhanced structural integrity and wind-diverting ability for a building having an overhang wherein the invention comprises a diverting means supported by a frame means, the diverting means using a fastener means to couple to the diverting means and the invention further adapted to couple to the overhang as defined by a horizontal support member provided by the building and a vertical support member provided by the building. 
         [0012]    In a second embodiment, the present invention comprises a wind-diverting free-standing structure, the structure comprising a membrane element suspended on a frame element, the frame element cooperating with a plurality of vertical support elements placed on a windward side of a particular building of interest, the vertical support elements being rotateable about an axis whereby the membrane element is positionable from a first generally vertical position to a second position whereby the second position enables high-winds to be diverted around, over, or both a free-standing building. 
         [0013]    The present invention comprises a diverting means comprising a fabric panel having a membrane element. The membrane element comprises a lightweight and flexible material such as fabric or plastic. Some contemplated materials suitable for the membrane element include Kevlar, nylon, polypropylene, canvas, waxed canvas, sail cloth and other similar materials. In a preferred embodiment the membrane material substantially blocks high-wind speeds but also permits—at a microscopic level—water and vapor permeation so as to “breathe”, thus enabling moisture or condensation positioned between the present invention and the exterior of the building to escape. Gore-tex brand fabric treatment applied to known nylon materials provides sufficient wind resistance and moisture resistance and yet permits evaporation of trapped moisture, as is well understood in the art. 
         [0014]    A frame means comprises a frame element comprising a two-dimensional web or structural supports for the mesh element. One contemplated frame element comprises a plurality of interconnected and coupled metal straps. A common metal strap consists of a “binding strap” such as a one-inch wide by ⅛″ deep band of material cut to suitable lengths. These bands or straps are placed in tension stretching them across the mesh material and bonding or otherwise fastening the bands to the fabric mesh. High-strength adhesives provide a continuous seam along the interface between the band and the membrane material. By placing the frame element in tension, the assembly of bands and mesh material forms a rigid structure that can effectively divert wind or block wind. Further, by releasing the tension, the band material being flexible in one direction, enables an easy rolling of the assembly for storage or when otherwise not in use. 
         [0015]    The advantages of the present invention over existing attempts includes:
       Lightweight materials for both the diverting means and framing means;   Inexpensive materials that are easily formed, cut-to-length, adapted for size using common hand tools readily available to most home-owners.   Easy to collapse assembly enables rapid tear-down and storage;   Lightweight design enables rapid deployment by the home-owner;   Breathable fabrics allow permanent attachment to buildings without causing pre-mature deterioration of the structure due to moisture build up;   Versatile design enables invention to be used as a privacy screen during normal weather patterns and yet enables a rapid deployment to a high-speed wind-diverting stand-alone structure;   Diverting elements may be pre-fabricated to given sizes for convenience; and   Simplicity of design and simplicity of elements enables custom sizing and rapid adoption for use by using at-hand supplies.

The fabric like material includes canvas, plastic, or other similar cloth-like material that resists moisture and can withstand the tensile forces typically experienced during hurricane force winds. The tensile support frame element is a coated steel strap element, similar to a banding strap, that easily rolls up and provides a generally flat surface suitable for an adhesive, the adhesive being selected to couple the fabric to the banding material. The frame element configures to generally following the perimeter of the fabric and additional cross braces may be required for larger panels.

Further, the system includes an anchoring means adapted to releasably couple to the block shield, the anchoring means comprising a ground-penetrating conduit comprising a plurality of dispensing-holes and a pervasive-adhesive adapted to flow through the conduit and permeate the ground. The anchoring means couples via tension cables to various attaching points on the frame element, for example. 
         [0028]    In a second embodiment, the present invention contemplates a system for protecting a structure from debris during a windstorm, the system comprises a block-shield comprising a rigid panel system; a securing means; and an attaching means. Specifically, this embodiment contemplates a rigid panel system comprising a plurality of panel elements wherein a first panel element is hingeably coupled to an adjacent panel element in an accordion-like manner whereby the first panel adapts to selectively rotate about 180-degress to fold over the adjacent panel or alternatively align with the adjacent panel in a single planel.

         [0030]    This embodiment further includes a securing means for selectively locking the block-shield to the structure, the securing means comprising a key-device adapted to engage a lock-mechanism and wherein the key-device comprises a socket plug having a uniquely shaped pattern adapted to mate to the lock-mechanism wherein the lock-mechanism comprises a lug-bolt having the same pattern on a head. 
         [0031]    One possible attaching means includes a fastener adapted to couple to the block-shield and releasably couple to the structure. 
         [0032]    Another possible attaching means comprises a channel-device coupled to a lower portion of the structure and a fastener adapted to couple to the block-shield and releasably couple to an upper portion of the structure.

     DESCRIPTION OF THE INVENTION 
       [0063]    Possible embodiments will now be described with reference to the drawings and those skilled in the art will understand that alternative configurations and combinations of components may be substituted without subtracting from the invention. Also, in some figures certain components are omitted to more clearly illustrate the invention. 
         [0064]    Briefly, in one embodiment, the present invention comprises a wind blocking or wind-diverting system designed to redirect airflow around and over a structure, such as a site-built home or a manufactured home without foundation. Although many of the exemplary representations of the present invention discuss suitability to houses, a person of ordinary skill in the art will appreciate that the devices, systems, and methods of the present invention work equally well for all structures, permanent, temporary, or semi-permanent, including, but not limited to mobile homes, office buildings, or tents. 
         [0065]      FIG. 24  shows a representative prior-art structure, such as a home with overhanging eaves and illustrates a problem with directing wind in the prior art. During intense winds, the windward wall receives the brunt of the effective wind force. Upon impacting the vertical exterior wall, the wind is fractured into multiple paths; part of the wind penetrates the exterior wall, some escapes horizontally and is diverted around the building, some is directed downward to the ground and then spirals upward, and a significant portion of the wind is diverted upwards. The upward flow of air is trapped by the eave-overhang and, in intense wind conditions, the upward flow can weaken or cause catastrophic failure of the roof system. 
         [0066]    One embodiment of the present invention includes a system for diverting wind around a structure and simultaneously reinforcing the structure. This system  10 , illustrated in  FIG. 1 , for example, includes a block-shield  12  comprising a fabric-like material forming a generally rectilinear panel  14  having a frame element  16  adhesively coupled to the fabric-like material (the adhesive is not illustrated in the accompanying figures). An attaching means  18  couples to the block shield  12  to secure the block-shield in a generally fixed position relative to the structure. The attaching means  18  includes a lashing element  20 , which, at one end, selectively couples to the frame element  16  and, at an opposite end, the lashing element couples to a tension device  22 . In turn, the tension device selectively and removably couples to an anchoring means  24  such as a stake embedded in the ground, a fastener attached to the structure&#39;s foundation, a ground-anchor (such as coated steel metal ground anchors with integrated auger available from www.detailedplay.com/AccHardware.htm), or other well-known means for securing cables or tension-wires to the ground. One possible lashing element includes a hook and ratchet lashing device common to over-the-road trailers and container-trucks, for example. Another possible lashing element includes cargo-lashing device available from Container Technics of Antwerp, Belgium. Another possible lashing device includes a scaled-down version of the Gigant Ratchet available from Braun of Neumarkt-Poelling, Germany and on their web-site at www.braun-sis.de. Those skilled in the art will appreciate than many other lashing devices will work equally well. 
         [0067]    Another embodiment of the present invention, the system  10  includes a frame element  16  that consists of a a generally flat banding strap-like member adapted for tensile support of the fabric-like material, the frame element further adapted to selectively and releasably couple to the structure and couple to the attaching means.  FIG. 2  details a portion of the fabric-panel block shield  12 . A fabric panel  14  (although shown as a generally rectilinear panel in the various figures, any shaped panel could easily be incorporated in the present invention including custom-fit panel that are sized to order), adheres to the frame element  16  using industrial-strength adhesives formulated to bond metal to fabric and withstand the temperature cycling and moisture penetration typically encountered homes and buildings in the United States. The fabric-panel  14  can be of any resilient fabric-like material similar to canvas, Kevlar, plastic, and the like. The frame  16  includes attaching points  26  at various locations so that at least one, and more commonly, a plurality of attaching means may selectively couple to the frame. By placing the frame in tension over a structure, the block shields divert wind and also add reinforcement to the structure to resist lifting of the structure from the ground or foundation during windstorms. 
         [0068]      FIG. 3  shows one possible anchoring means consisting of a ground anchor having an elongated cylindrical body  28  with a plurality of through-holes  30  in the body. The cylinder is inserted in a pre-dug hole in the ground and backfilled or, alternatively, is screwed into the ground. An open top on the body then allows a semi-solid suspension of concrete or adhesive to be poured into the top of the body and flow out the holes an into the surrounding ground. Once solidified, the concrete or adhesive serves as a solid anchor for the system  10 . 
         [0069]      FIGS. 4 and 4A  show a suitable securing means consisting of a locking lug bolt  44  having a threaded end and an oppositely arranged head with a key-feature. A mating key-device inserts into the key feature, thus enabling a standard socket wrench to tighten or loosen the fastener. Thus, the present invention includes a securing means for selectively locking the block-shield to the structure, the securing means comprising a key-device adapted to engage a lock-mechanism and wherein the key-device comprises a socket plug having a uniquely shaped pattern adapted to mate to the lock-mechanism wherein the lock-mechanism comprises a lug-bolt having the same pattern on a head. 
         [0070]    In another embodiment, shown in  FIG. 5  for example, the system  10  includes a plurality of block shields  12  whereby a first block shield couples to a second, adjacent block shield by interlinking the respective frame elements. Fasteners, such as nuts and bolts, are readily available for use to interlink adjacent panels. 
         [0071]    In one embodiment, the fabric-panel  14  block shield  12  attaches directly to the structure. For example, the shield can be placed at an offset angle to divert airflow away from an overhang such as an eave. In this embodiment, the shield attaches directly to the structure using a fastener, such as a wood screw.  5 . Alternatively, as  FIG. 6  shows, the block shield attaches to the structure at one end and to an anchor device embedded in the ground. In yet another embodiment, a plurality of panels  14  are interlinked to extend entirely over the structure and are anchored on opposite sides of the structure directly to ground anchors. This approach is ideal for mobile homes or RV&#39;s because they do not have a suitable foundation. 
         [0072]    The system readily adapts to receive additional support devices including a guide-wire coupled to the frame element at one end and coupled to an anchoring means at a second, opposite end of the guide-wire, the anchoring means. 
         [0073]    One particular advantage of the fabric-panel block shield system according to the present invention, and as  FIG. 7  shows, includes ability of the panels to be rolled up for storage and easily handling. One contemplated system uses a plurality of standard sized block shields  12  that readily adapt to be interlinked based on the size-requirements of a particular structure. The panels may be pre-linked prior to deployment, or may be linked in the field during installation. The advantage is clear, should a region be faced with the potential of property-damaging severe weather, a plurality of standard block shields can be delivered in rolls on a large transport device and rapidly configured to protect specific structures. Alternatively, prudent property owners can prepare for future severe weather and purchase a requisite quantity of the standard size panels, or order custom sized and configured panels, and layout the desired configurations ahead of time. Then, simply roll them up and store them nearby, ever-ready to be deployed should the need arise. 
         [0074]    In another embodiment the present invention contemplates a system for protecting a structure from debris during a windstorm, the system comprises a block-shield comprising at least one rigid panel. The rigid panel, shown in  FIGS. 8 ,  9 , and  10 , for example, further includes a resilient deformable material. For example, a simple form of the rigid panel consists of a traditional 4′×8′ plywood sheet of most nominal thicknesses including about ¼″ to about ¾″ thick.  FIGS. 8 ,  9 , and  10  show a block shield  12  in the form of a simple, rectilinear panel  30  according to this possible embodiment of the present invention. However, other sizes, shapes, thicknesses and materials would work equally well. For example the material selection includes oriented strand board (OSB), aluminum, steel, carbon fiber, or plastic materials of varying thicknesses. The shape may be altered as well. A modular designed system includes various shapes from a standard set, but a customized system that is designed to a structure-specific configuration would work equally well. 
         [0075]    The rigid panels  30  are arranged in various relationships to the structure. In one embodiment, illustrated in  FIG. 11  for example, the rigid panel  30  mounts under a roof eave, or other similar overhang, at an angle with respect to the structure&#39;s vertical side wall to divert wind from lifting the horizontal roof eave. In another embodiment, illustrated in  FIGS. 12 ,  13 , and  14 , a relatively flat rigid panel  30  mounts generally parallel to the outside wall of the structure and slides along a track from a first storage position on the structure selected to stack multiple panels out of the sight line of windows and doors, yet slide across selective parts of the side wall or the entire facade of the structure as necessary. In yet another embodiment, illustrated in  FIGS. 15 and 16 , a rigid panel  30  mounts at an angled position relative to the vertical side wall and covers a portion of the sidewall, while also diverting wind from under the roof overhang. 
         [0076]    Cooperating with these aforementioned embodiments, a securing means, as shown by  FIG. 4 , adapts to selectively couple and secure the panel to the structure. Alternatively, the securing means includes typical fasteners adapted for use for mounting to foundation walls of concrete, or to stud-walls of wood or metal studs. 
         [0077]    In another embodiment, the present invention includes an attaching means for selectively and releasably coupling the block shield  12  to the structure, the attaching means comprising a first generally U-shaped channel element having an open top, the first U-shaped channel element adapted to couple to the structure and support the block shield at a bottom edge of the rigid panel. One possible embodiment contemplates using a combination of smaller and larger channel elements  32 , shown in  FIGS. 17 and 18 , for example. The U-shaped channel element  32  selectively mounts to the structure to orientate the open portion opposite the panel-engaging surface  38  as required for a bottom or top use. The channel element  32  has a pair of oppositely facing side walls, a front wall  36  and a back wall  34 . A plurality of fastener slots  40  are included on both walls  34  and  36  to facilitate installation of the channel on the structure. Further, symmetrical channels further enhance the modularity of the system, requiring fewer separate components and enhancing the ease and speed of installation. The fastener slots  40  are also useful for securing individual panels in place, or for inserting fasteners as hard stops to prevent individual panels from being positioned out of place on the structure or for falling off the channel. 
         [0078]    In an alternative embodiment, a plurality of rigid panels couple together . Accordingly a first rigid panels  30  hingeably couples to an adjacent, second panel element in an accordion-like manner whereby the first panel adapts to selectively rotate about  180 -degress to fold over the adjacent panel or alternatively align with the adjacent panel in a single plane. 
         [0079]    In another embodiment individual panels adapt to selectively and releasable couple to adjacent panels using fasteners whereby the panel system forms an interlinked system of the plurality of panel elements to selectively configure to protect a selected feature of the structure. 
         [0080]      FIGS. 12 ,  13 , and  14  illustrate a block shield system  12  consisting of a first channel element  32  installed as a retaining means for the top edge of a rigid panel  30  and a second channel element installed on a structures as a bottom edge support. The top channel element includes either a continuous channel or a plurality of individual elements arranged in sufficient proximity to an adjacent channel to ensure that panels are adequately supported for the features being protected. Likewise, the bottom channel elements are similarly adapted. 
         [0081]      FIGS. 15 and 16  illustrate two additional embodiments of the present invention including a block shield system  10  having a rigid panel member  30  held between a bottom channel element  32  using the tensile characteristics of the resiliently deformable panel  30 . A top support element, such as angle bracket element  42  or another securing means (not illustrated) readily retains the upper edge of the panel  30 . 
         [0082]    In another embodiment, the rigid panel elements  30  include an anchoring means adapted to releasably couple to the block shield, the anchoring means comprising a ground-penetrating conduit such as the anchoring means  24  shown in  FIG. 3  and described above. 
         [0083]    In another embodiment, the block shield system  12  further includes an anchoring means adapted to selectively couple to the structure, the anchoring means comprising a bar-element adapted to engage the attaching means. 
         [0084]    In yet another embodiment, the block shield system  12  includes a rigid panel system  30  to protect the structure from flying debris during a severe-weather event and a wind-diverting means to re-direct airflow around the structure, particularly when the structure has overhangs that would act as airfoils during a wind-storm. In this embodiment the system includes a block-shield comprising a rigid panel system comprising a first panel member and a second panel member, each respective panel member further comprising a rectilinear sheet material formed from a resilient material and comprising a generally planar face, a bottom edge arranged generally perpendicular to the face and a top edge opposite the bottom edge; a securing means adapted to selectively engage the block-shield; an attaching means comprising a first channel element coupled to the structure, the first channel element cooperating with the structure to form a U-shaped channel with an open top whereby the open top adapts to selectively receive the bottom edge of the first panel and whereby the bottom edge is supported by the channel element, the attaching means further comprising a second channel element coupled to the structure, the second channel element cooperating with the structure to form a U-shaped channel with an open bottom whereby the first panel is retained in position relative to the structure by a sidewall of the second channel element; and an angled support means coupled to the exterior wall of the structure and to the overhang, the angled support means further comprising means for coupling to the second panel member. 
         [0085]    Further, this embodiment contemplates that the system includes the securing means having a key-device adapted to engage a lock-mechanism and wherein the key-device comprises a socket plug having a uniquely shaped pattern adapted to mate to the lock-mechanism wherein the lock-mechanism comprises a lug-bolt having the same pattern on a head. 
         [0086]    Alternatively, this embodiment configures to include a securing means comprising a plurality of vertically arranged bar-elements adapted to selectively engage in the first and second channel elements. The bar elements cooperate with panels to add additional strength to the panel by incorporating a fastener that couples the bar to the panel. For example, a rigid-panel couples to a bar at a mid-point on the bar using a fastener. The bottom end of the bar pivotably mounts to the bottom channel and the top end of the bar couples to the overhang of the structure, for example. 
         [0087]    In another embodiment, the present invention contemplates a block-shield system consisting of a privacy screen that adapts to divert wind. In an upright and generally vertical position, the privacy screen serves as a fence next to a house, for example. At the onset of a severe wind storm, a user rotates a vertical structural element to an oblique angle away from the prevailing wind. Accordingly, the privacy screen pivots away from the wind to act as a foil, diverting the airflow upwards (and over the structure). 
         [0088]    In an alternative embodiment of the present invention, the wind-diverters include a structural integrity improvement for buildings using angled support arms of varying configurations. A structural integrity improvement for buildings, the improvement comprises angled block elements for insertion under overhangs of buildings whereby the angled-block elements attach to the building. The structural integrity improvements include a frame member having an angled support arm and two arms at a right-angle, the three arms form a triangle. The angled block elements, ideally, are pre-configured in a set of discrete sizes that can be combined together. Thus, the set, of limited number, can be combined and configured in a large number of combinations depending on the particular need of a given application. In one embodiment, the angled block member comprises a wood frame with sheet-material, such as plastic or canvas, for example, adhered using an adhesive. In another embodiment the frame is a wire frame. In yet another embodiment the sheet material is rigid, such as wood. The angled block mounts or couples to a structure by adhesive or by fasteners. 
         [0089]    One advantage of the present system is that it can be quickly configured at the installation location using widely available materials. For example, plastic sheet material, banding straps and commercial adhesives are readily available from major home and building supply stores. Moreover, these readily available materials are easily manipulated using common tools. Thus, the system of the present invention can be quickly installed prior to a windstorm, for example. In this embodiment the wind-blocker comprises a sheet material, an adhesive, a coupling element and a tensioning element comprising a banding strap. 
         [0090]    In the aforementioned embodiments, the present invention contemplates an efficient and easily installation process for a homeowner or business owner and, accordingly, the block-shield system includes a panel system of a plurality of generally rectilinear, rigid panels formed from a semi-resilient material such as pressboard, plywood, plastic, carbon fiber, aluminum or other similar sheet-like materials that will resist penetration from flying debris during a windstorm, yet be sized and weighted so that a single user or two-person team can easily handle and install the panels immediately prior to or during a weather emergency. The resiliency of the panel material enables the one or two-person work crews to snap panels into the attaching means (such as the U-shaped channel elements described elsewhere in this disclosure). Individual panel elements can selectively couple together by fasteners commonly used and understood by persons skilled in this art. In one alternative embodiment, the plurality of panels are free-standing with respect to each other and are not coupled together. However, in an alternative embodiment, the panels are hingeably coupled together in two, three, or four pieces, although other multiples would work as well. In this hinge-arrangement, multiple panels can fold and stack to minimize space when not used. In yet another embodiments, the panel elements may be coupled by a membrane that would act like a hinge element or as an expanding member similar to panels in an accordion door. 
         [0091]    For example, the block-shield system according to the present invention adapts to install over the exterior surface of a structure such as a house, store, warehouse or other similar building having at least one vertical exterior wall and a roof structure. The building may or may not have overhangs, such as the roof or windows or balconies. The block-shield system includes one or more panel elements that are selectively placed over the exterior of the structure using attaching means that are placed or coupled to the structure ahead of time. 
         [0092]    In certain embodiments, the block-shield system includes a plurality of panels sufficient to cover entire exposures of a structure and includes panels to cover every exterior surface. However, in other embodiments, the system may be selectively applied to the exposure of the structure most susceptible to weather-related damage during a storm. Further, in other embodiments specific panels may be selectively applied only over window openings, doors, or to protect overhanging elements, such as under roof eaves. 
         [0093]    One possible attaching means comprises a system of generally U-shaped channel bracket elements with three sidewalls forming a rectilinear channel with one open side. The channel elements further include a plurality of through holes periodically spread over at least one of the sidewalls and adapted to allow standard fasteners, such as wood screws or nails, to pass therethrough and thus couple or attach the channel elements to an exterior surface of the structure. These channel elements may be incorporated into new structures at the design stage, or can be added as a retro-fit to existing structures. The channel elements can be made from steel, aluminum, wood, or plastic, for example, as long as they are sturdy enough to support several panel elements. Ideally, the channel elements are installed, attached, or coupled to the structure well-in-advance of any inclement weather. Then, during a weather event, the panel elements are simply arranged on the channel elements and locked or snapped into place. 
         [0094]      FIGS. 22 and 23  show an alternative embodiment of the block shield system  10  according to the present invention using a combination of modular, standardized panel elements  30  with a custom panel element  31  configured for a corner of the structure. A plurality of angle elements  42  are pre-positioned and coupled to the structure and, when needed the panel elements  30  and  31  are arranged on the angled elements  42  to divert wind from under an eave or other overhang. Additional fasteners may be used to further secure the panels in relative position.  FIGS. 19 ,  20  and  21  further detail a method of the present invention of inserting a rigid panel  30  into an angle bracket element  42 . 
         [0095]      FIG. 25  shows an alternative angle element of the present invention whereby a block shield rigid panel element  30  hingeably mounts via a hinge mechanism  48  to a bottom channel of the angle element  46 , which includes a curvilinear top bracket with a slot for the panel to rotate from a near vertical position to an angled position. Additionally, a side panel completes the installation to prevent unwanted airflow from redirecting behind the panels. This angled element  46  easily adapts to cooperate with other embodiments of the present invention. Accordingly, a plurality of rigid panel elements may be stacked on top of each other while being held by the curved angle element  46  and may be selectively slid into position across the facade of the structure. Then each individual panel is pivoted into an angled position and click-locked into place to divert wind during a wind storm. 
         [0096]    In certain embodiments the channel elements need to be sufficiently wide to allow several stacked panels to be supported simultaneously. Thus the stacked panels can be temporarily stored in an out-of-the-way segment of the exterior of the structure and then simply slid into place when needed to protect the full length of the structure from the weather event. 
         [0097]    Although the invention has been particularly shown and described with reference to certain embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention
