BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to storm shutters for protecting homes, buildings and other structures from wind and storm related damage, and more particularly to a light transmitting storm shutter assembly that provides sufficient resistance to hurricane force winds and impact from windborne debris while allowing light transmittance into the protected structure.
2. Description of the Background Art
The United States has experienced 44 weather-related disasters in the past 20 years, each of which has caused in excess of $1 billion in damages. Of these 44 disasters, 38 occurred between 1988 and 1998 causing in excess of $170 billion in damage.
Population growth along the coastline of the United States has resulted in an increased risk to life and property from hurricane related damage. There are approximately 36 million permanent residents along the hurricane-prone coastline of the United States, with areas such as Texas, Florida, and the Carolinas, where hurricanes frequently strike, experiencing rapid population growth. In addition, many coastal areas experience substantial but temporary population increases from holiday, weekend, and vacation visitors during hurricane season.
Homes, buildings and other structures, suffer substantial damage when storm generated winds, and particularly windborne debris, penetrate the structures through window and door openings. Hurricane shutters have long been used as barriers to protect window and door openings from the effects of storm generated winds. Equipping homes and other buildings with hurricane protection in the form of storm shutters is one of the most prudent actions one can take to protect life and property.
Accordingly, the background art reveals a number of storm shutters designed for removable installation on homes and buildings. Conventional storm shutters typically consist of corrugated metal panels affixed to the outside of a given structure. For example, U.S. Pat. No. 2,878,536, issued to Becker, discloses a shutter structure having overlapping corrugated panels. U.S. Pat. No. 4,333,271, issued to DePaolo et al., discloses a hurricane panel system for covering windows and doors. The '271 patent discloses a plurality of corrugated metal panels arranged in overlapping relationship to provide a protective structure. U.S. Pat. No. 5,345,716, issued to Caplan, discloses a storm shutter system comprising a combination of individual, interlocking modular elements. U.S. Pat. No. 5,852,903, issued to Astrizky, discloses a hurricane shutter comprising a pair of normally open doors that are swingable to a closed position. U.S. Pat. No. 5,911,660, issued to Watson, discloses a storm panel comprising a plurality of interlocking tiles interlocked together by a plurality of dovetail joints.
A significant disadvantage with conventional storm shutter panels is that installation of the panels over all of the window openings prevents light from entering the structure. Accordingly, if power is lost, as often happens during severe storms, the occupants of the structure find themselves in total darkness. Thus, a number of references disclosed in the background art reveal attempts to provide storm shutters that provide sufficient impact resistance while allowing light to enter to building.
For example, U.S. Pat. No. 5,918,430, issued to Rowland, discloses a removable storm shield comprising convex panels. U.S. Pat. No. 5,996,292, issued to Hill et al., discloses a perforated shutter system wherein at least one panel is formed of corrugations. U.S. Pat. No. 3,358,408, issued to Cooper et al., discloses an insulated light transmitting panel construction having corrugations in the side edges thereof. U.S. Pat. No. 4,685,261, issued to Seaquist, discloses a removable translucent storm shutter consisting of a ½″ thick polycarbonate sheet in an aluminum channel frame. U.S. Pat. No. 5,595,233, issued to Gower, discloses hurricane shutters formed of transparent, double-skinned panels that are strengthened by rods extending through the end channels. The panels are mounted side-by-side to cover the expanse of a window or door being protected. U.S. Pat. No. 5,457,921, issued to Kostrzecha, discloses a storm shutter in the form of a “kit”. The kit includes a plurality of corrugated shatter-resistant and transparent plastic sheets fastened to the structure using a mounting mechanism and fasteners inserted through keyway slots.
While the use of clear plastic panels, such as Polycarbonate panels, provides light transmittance, the use of plastics can substantially reduce structural integrity and impact resistance as plastics are generally not as strong as the metal alloys, such as aluminum or steel, typically used to fabricate storm panels as disclosed in the background art. Accordingly, the clear polycarbonate storm panel structures of the background art must be fabricated to a greater thickness and/or require additional bracing and hardware that complicates installation and increases cost. For example, the '921 patent discloses corrugated polycarbonate storm panels that use stiffening cross bar members. Furthermore, the '233 patent discloses panels that are strengthened by rods extending through channels. Since weather reporting agencies typically allow a mere 24 hours in which to install storm protection installation time is an important factor.
Accordingly, there exists a need for a light transmitting storm panel assembly that avoids the disadvantages present in the storm panels disclosed in the background art.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a light transmitting storm shutter system for homes, buildings and the like that overcomes the disadvantages present in the background art. A storm panel system according to the present invention includes a combination of corrugated aluminum and clear polycarbonate panels arranged in alternating adjacent relation over a given window or door opening. The aluminum panels provide structural integrity while the polycarbonate panels allow light to pass through the storm shutter system.
More specifically, the storm panel system comprises a combination of full width corrugated aluminum panels with half width corrugated polycarbonate panels installed therebetween in partially overlapping relation. The combination of full width aluminum panels and half width polycarbonate panels provides a storm shutter system that is substantially stronger and more resistant to impact deflection than the light transmitting storm shutters disclosed in the background art, and eliminates the need for additional hardware, supports, bracing etc.
Accordingly, it is an object of the present invention to provide an improved storm shutter assembly for protecting building openings from windborne debris.
Still another object of the present invention is to provide a light transmitting storm panel that has substantial impact resistance.
Yet another object of the present invention is to provide a light transmitting storm panel assembly for protecting building openings from windborne debris in compliance with the latest and strictest building codes.
Still another object of the present invention is to provide a light transmitting storm shutter assembly that achieves a high level of impact resistance without requiring the use of additional stiffeners or cumbersome cross-bracing.
Yet another object of the present invention is to provide a light transmitting panel system capable of being used in an awning or overhang configuration.
In accordance with these and other objects that will become apparent hereinafter, the instant inve
