ROOF SPOILERS
Field of the Invention
The present invention is directed to a method and apparatus to provide stability for a roof. More particularly, the present invention can be affixed to a roof before a storm in order that damage from the wind can be minimized.
Description of the Related Art
Hurricanes and other natural disasters can do enormous damage to a house.
What is needed is an improved way to stabilize a roof of a house. Summary of the Invention
It is an aspect of the present invention to provide a roof spoiler to help stabilize a roof in the event of large winds (such as a hurricane) which can destabilize the airflow in a direction which can reduce damage to the roof.
The above aspects can be obtained by an apparatus that includes a bracket mounted to a roof; and a rotatable flap connected to the mounting bracket to rotate around an axis, wherein the flap can be in both a retracted position and an extended position.
These together with other aspects and advantages which will be subsequently apparent, reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Description of the Preferred Embodiments
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
The present general inventive concept relates to an apparatus and method to help stabilize a roof (and thus a house) in the event of catastrophic wind, and to help prevent wind damage to the house. At significant velocities, wind life can be tremendous and can peel the roof deck up and off the house or other structure, because the root deck prevents flexural loads in the walls. If it is removed the walls and other structures fail rapidly after that.
In an aircraft, it is the stability of the air flow (laminar flow) that creates the lift effect causing flight. A similar effect is what peels off a roof deck in a hurricane or other wind-event.
The simplest form of the invention would be to simply screw down a piece of angle to the roof in several places. This could serve to spoil the airflow of storm (as discussed herein). A drawback to this method is that it would not look aesthetically pleasing.
The present invention can provide folding flaps (typically automatic) that can look more like the rest of the roof when not needed.
Figure 1 A is a drawing of extended spoilers and air flow, according to an embodiment.
A roof 100 contains a first air spoiler 102 and a second air spoiler 104. The two air spoilers disrupt (or spoil) the airflow, so that the air flow is not concentrated on the roof which can cause damage.
Figure 1 B is a drawing of a roof and respective airflow without spoilers.
Note that the airflow develops a laminar flow which can cause damage to the roof and supporting structure.
Figure 1 C is a drawing of a roof and pressure exerted therein.
Note that as air stacks against the roof, its velocity increases. As the velocity increases, the pressure it exerts against the surface drops. After air passes an obstruction, then it must spread out again. Compare the air flow in Figure 1 A with that in Figure 1 B.
Figure 2A is a drawing illustrating various views of spoiler assemblies, according to embodiments.
Box 200 illustrates an embodiment of the present invention using a retractable bracket. A first connector 201 is connected to a second connector 202. A side view of the pair of connectors 204 is illustrated. The entire assembly is illustrated as spoiler 206, which includes a flap 207. A partially retracted spoiler 208 and a completely retracted spoiler 210 are illustrated. Connectors 201 and 202 can be the same part with a pivot pin or bolt in the middle so that they can fold in the juncture.
Figure 2B is a drawing illustration comprising further views of the spoiler assemblies, according to embodiments.
In another embodiment, a side bracket 212 is used which can mount onto a roof. The mounting can be accomplished using any mounting method, such as screws. A side view of the side bracket 214 is also illustrated. The side bracket can have a circular groove to receive and guide the flap 216. The flap 216 is prevented from extending beyond a portion where the groove allows. A flap side 218 is also illustrated.
In a further embodiment, a lanyard 220 (or cable, rope, etc.) can be used to restrict the opening of the flap to a desired angle (e.g. 90 degrees). See Figures 7A, 7B, and 7C for more detail on this embodiment. The lanyard 220 can have two eyelets that can be used to attach to the flap and the bracket. The lanyard can replace using the brackets (e.g. connectors 201 202). A bracket 224 can have two sides each at a right angle to each other. Each side can have three (or any number) of holes. One side of the bracket 224 can be mounted onto a roof directly (by using screws, nails, etc.) A bracket 217 can be connected to a side of the bracket 224 by using a screw or other connecting apparatus.
Figure 3A is a drawing of various parts to air spoilers in a retracted position, according to embodiments.
A left hand end bracket 336 and a right hand end bracket 332 have a flap connected there between 328. A left screw 334 attaches the left hand end bracket 336 to the roof deck 326. A right screw 330 attaches the right hand end bracket 332 to the roof deck 326. A stop rod 331 can be used to guide the flap 328.
An end bracket 338 in a retracted position can have a circular groove to receive the stop rod 331 which is currently in the retracted position. Three (or any number) of screws can be used to mount the end bracket to the roof. Thus, the flap rotates around the axle.
Figure 3B is a drawing of various parts to air spoilers in an extended position, according to embodiments.
The flap in the extended position 340 is also illustrated. A side view of the slap 343 includes a stop rod and an axle. An end bracket in an extended position has the stop rod in the fully extended position.
Figure 4 is a drawing of a roof with brackets attached, according to an embodiment. A first bracket 414 and a second bracket 412 are secured to the roof (by nails, screws, glue, etc.) over roof shingles 410. A flap 415 can be inserted between the brackets 412 and 414. A flap 415 can be inserted into an end bracket using a sheet metal screw as an axle. A sheet metal screw can also be used as a stop rod (for the embodiment as illustrated in Figure 3, item 358).
Figure 5 is a drawing of a roof with roof spoilers, according to an embodiment.
The roof 500 has a plurality of roof spoilers to spoil the airflow. The spoilers may be placed in an orientation such as that illustrated relative to the wind currents (portrayed as arrows).
Figure 6A is a drawing of a roof spoiler with a pivot, according to an embodiment. The end bracket can be extended to act as rudder, The flap with the end brackets can rotate around a pivot and self steer into the wind. The pivot can be inserted into a roof mount which can be mounted onto the roof.
Figure 6B is a drawing of a roof spoiler with a rudder, according to an embodiment. A rudder can also be attached to the flap which can self steer into the wind.
Figure 7A is a drawing of a retracted roof spoiler using a lanyard, according to an embodiment.
A bracket 700 connects to a flap in a retracted position. An additional bracket (not pictured) can be located behind the bracket 700 which also connects to the flap. Figure 7B is a drawing of a semi-extended roof spoiler using a lanyard, according to an embodiment.
The bracket 700 connects to a partially extended flap 702 and a lanyard 704.
Figure 7C is a drawing of a fully extended roof spoiler using a lanyard, according to an embodiment.
The bracket 700 is connected to a fully extended flap 702. The flap has a first end which is connected to the lanyard 704. The lanyard 704 is connected to an end of the bracket 700. The lanyard 704 can also be connected to a bracket, shingle, or any other piece of the apparatus that will secure the lanyard and prevent the flap 702 from extending beyond 90 degrees (or any other angle) in the wind.
Figure 7D is a drawing of a semi-extended roof spoiler using brackets, according to an embodiment.
A bracket 710 is attached to a flap 712. The bracket 710 is connected to a first connector 714 and a second connector 716. An additional bracket (not pictured) can exist behind the bracket 710 in order to secure the second connector 716.
Figure 7E is a drawing of a fully extended roof spoiler using brackets, according to an embodiment.
The bracket 710 is attached to the flap 712. The first connector 714 is connected to the second connector 716. The second connector is connected to the bracket 710. The first connector 714 and the second connector 716 serve to allow the flap to extend in the wind, while allowing the flap to automatically retract when there is no wind.
One way to manufacture the present invention would be to build punch press dies for each individual part and run them from coil steel (preferably using corrosion resisting material) on high speed presses with automatic feeding un- coilers.
One use can be to place several rows along a lower edge of a roof in a staggered alignment. A row at the peak of the roof may be preferred. The spoilers can be made to match the roofing shingles by coating them with the same aggregate as the singles or painting them the same colors as the roof.
The measurements depicted in the figures are measured in inches and are only suggestions. Other measurements, sizes, configurations, etc. can be used as well.
The many features and advantages of the invention are apparent from the detailed specification and, thus, it is intended by the appended claims to cover all such features and advantages of the invention that fall within the true spirit and scope of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
