Definitions

  • the invention disclosed herein is a device which substantially equalizes air pressures present inside and outside of a building during high wind events, such as hurricanes and tornadoes.
  • High winds are associated with many bad weather events, such as hurricanes and tornadoes, and affect fixed structures, such as buildings, in a number of ways.
  • One way is often a differential between air pressure within the building and outside.
  • a high wind event may generate a positive pressure event where air pressure outside of a building quickly exceeds or substantially exceeds the air pressure within the building.
  • a negative pressure event is created where air pressure inside of a building quickly exceeds air pressure outside of that building.
  • a combination of positive and negative pressure events can be created, either inside or out. When air pressure ratings of the building's doors and windows are exceeded, they fail, leading to potential loss within the building, or loss of the building itself.
  • a device is needed which is capable of mitigating pressure differentials created between a building's interior and exterior during high wind events.
  • An object of the invention is to provide a device that substantially equalizes exterior air pressure and interior air pressure within a building during inclement weather, particularly high wind events.
  • Another object of the invention is to provide a low-cost and substantially maintenance free safety device for equalizing exterior air pressure and interior air pressure within a building.
  • a pressure equalization device suitable for use in a building or structure that is enclosed or semi-enclosed having an interior environment substantially insulated from an exterior (e.g., outdoor) environment.
  • the PED may be a device that, upon reaching a certain pressure differential threshold, allows substantial equalization of exterior air pressure and interior air pressure within a building during storm conditions.

  • One or more PEDs 200 may be installed within a wall 101 of a building. Multiple PEDs 200 may also be installed on separate walls 101 of a single building. The PEDs are configured to extend from at least the wall's 101 exterior to its interior, that is, outside to inside, or vice versa. The PEDs 200 may be positioned within the wall 101 to minimize visual appearance from one or both the exterior and interior. For example, the PED 200 may be installed a certain distance from the finished interior ceiling 107, preferably as close as possible, to minimize visual appearance. The PEDs 200 may also be painted or otherwise decorated to reduce visibility.
  • Figure 2 illustrates a cross-section of the preferred embodiment of PED 200 which includes an elongated member 202 that is configured to extend from an exterior to an interior of a wall 101. Therefore, the elongated member 202 may be any length depending on the thickness of the wall 101.

Alternatively, an inner diameter of the end caps 205 may be slightly larger than an outer diameter of the elongated member 202 and still achieve a snug fit.

  • the disc 208 may be configured to rupture or fail at particular air pressure differentials between the outside and inside air pressures.
  • the rupture disc 208 is configured to fail when an outside/inside air pressure differential exceeds approximately ten (10) pounds per square foot (psf). In other embodiments, the rupture disc 208 may be configured to fail when an outside/inside air pressure differential exceeds at least twenty (20) psf or thirty (30) psf. Still larger air pressure differentials may be used than the examples above.

  • the PEDs 200 disclosed herein may be constructed of various types of material.
  • the PED 200 may be a polymer, such as polyvinyl chloride ("PVC"), or others. PEDs 200 may be formed using all the same material.

  • PEDs 200 may be installed in existing walls 101 or in new construction. Methods of installing in an existing wall 101 include first drilling a small diameter pilot hole through the wall 101. A larger hole corresponding to an outer' diameter of the elongated member 202 of the PED 200 may then be drilled through the wall 101. The PED 200 is installed from the outside of the wall 101 to the inside, although it may also be installed from the inside to the outside in certain instances. After the PED 200 is properly positioned, any sealing material may be applied around the mounting flange 204 of the PED 200. Fasteners may be inserted through holes in the mounting flange 204 to engage the wall 101 and secure the mounting flange 204 to the wall 101.

  • the exterior end cap 220 is designed to snap onto and over the end of elongated member 202.
  • An end of the elongated member 202 protruding into the interior may be cut to a desired length relative to the interior wall material 106. Preferably, the end is cut to within less than one inch of the finished interior wall material 106.
  • An interior end cap 222 is then installed onto the elongated member 202.
  • the interior end cap 222 is designed to snap onto and over the elongated member 202. Minor touchup work may be performed to either or both the exterior and interior of the wall 101 for aesthetic purposes.
  • the end caps 205 may also be painted or decorated to minimize visibility.
  • an air pressure differential between the exterior and interior reaching a certain level may be sufficient to rupture the discs 208 on either end of the PED 200. That is, an outside air pressure that exceeds the inside air pressure within the building by a specified amount will rupture the discs 208 of the PED 200, which provides an open conduit for "communication" between exterior and interior pressures. This reduces the pressure differential by allowing exterior and interior air pressures to substantially equalize. For example, a lower air pressure within a building may increase to a level closer to a higher outside pressure. In another example, a higher air pressure within a building may decrease to a level closer to a lower outside pressure.
  • PED 200 may be designed to rupture at an air pressure lower than air pressure ratings of doors or windows in a building, thereby mitigating damage caused by high wind events.

Abstract

L'invention concerne un dispositif d'égalisation de pression (200) comprenant un élément allongé (202) disposé et conçu pour s'étendre entre un extérieur et un intérieur d'un bâtiment (100) et au moins un disque de rupture (208). Le disque de rupture (208) peut avoir n'importe quelle forme appropriée et est conçu pour se rompre lorsqu'une différence de pression de l'air entre l'extérieur et l'intérieur du bâtiment dépasse un certain seuil, ce qui permet aux pressions d'air de l'extérieur et de l'intérieur de s'égaliser sensiblement. Le dispositif peut contenir des coiffes d'extrémité (205) qui peuvent être fixées à l'élément allongé (202) par un ajustement serré ou un autre procédé approprié.
