US 9545775

US Patent 9545775, titled "Attachment systems and methods usable to form enclosures," was issued to an inventor, Samer U. Al-Azem, and is currently assigned to "Individual." The application for this patent was filed on May 1, 2012, and the patent was granted on January 17, 2017. The patent's legal status is active, with an adjusted expiration date of August 29, 2034.

Abstract:
The patent describes enclosures and panels used to form them. These panels feature a first (male) edge with fastening medium portions on its front and rear sides, and a second (female) edge with two flaps, each having a fastening medium portion on its inner surface. Panels are connected by engaging the flaps of one panel with the front and rear sides of an adjacent panel, forming a seal capable of maintaining a pressure differential.

Independent Claims Overview:

• Independent Claim 1: This claim describes an enclosure made from at least two panels. A first panel has a "male" edge with fastening material on both its front and rear sides. A second panel has a "female" edge with two flaps, each having fastening material on its inner surface. These flaps engage with the front and rear sides of the first panel, and this engagement creates a seal strong enough to maintain a difference in pressure across the panels.

• Independent Claim 5: This claim describes an enclosure that includes a wall formed from four panels (first, second, third, and fourth). Each of these panels has both a "male" edge (with fastening material on its front and rear sides) and a "female" edge (with at least two flaps, each having fastening material on its inner surface). The panels are connected sequentially: the second panel connects to the first, the third to the second, the fourth to the third, and the first panel connects back to the fourth. The connections between these panels collectively form a seal designed to maintain a pressure differential across opposing sides of the wall.
