Hurricane protection system

A hurricane protection system for precluding damage to windows during high wind conditions comprising, in combination:

• a rectangular window oriented in an essentially vertical plane with an inside and an outside, the window being supported by a peripheral sash;
• a wall in an essentially vertical plane having a rectangular opening defined by a horizontal header surface above, a horizontal sill surface below and spaced vertical jamb side surfaces there between, the surfaces supporting the sash and the window there within, each of the surfaces having at least one cylindrical hole to the outside of the window with the holes of the header surface being axially aligned with the holes of the sill surface and the holes of the jamb side surfaces being axially aligned;
• a ridged wooden sheet in a rectangular configuration positioned within the opening adjacent to but spaced from the sash and the window with an upper edge adjacent to the header surface, a lower edge adjacent to the sill surface and parallel side edges adjacent to the jamb side surfaces;
• a plurality of fixed retention mechanisms secured to the sheet adjacent to the lower edge, each fixed retention mechanism having a plate with apertures secured to the sheet, preferably by nuts and bolts, and with a downwardly extending finger with a lower end positioned in an associated hole of the sill surface and an upper end beneath the apertures secured to the plate by a weld;
• a plurality of supplemental retention mechanisms secured to the sheet adjacent to the upper and side edges, each of the supplemental retention mechanisms including a J-shaped finger with a short leg and a long leg terminating in a free end reciprocal between a locked orientation within an associated hole and unlocked orientation out of, but aligned with, an associated hole, each of the supplemental retention mechanisms including a bracket with a central face attached to the sheet by nuts and bolts, and with an inboard plate and an outboard plate extending at right angles from the central plate, the inboard and outboard plates having aligned apertures aligned with an associated hole for the reciprocal support of the long leg, the long leg having projections at an intermediate extent with a coil spring between the inboard plate and the projections urging the free end into an associated hole, the finger adapted to be retracted from the hole against the urging of the spring and rotated whereby the short leg abuts the inboard plate to maintain the finger out its associated hole;
• a pair of handles, each in a generally C-shaped configuration with interior ends secured to the sheet at a central extent thereof by nuts and bolts, and a central extent between the free ends and spaced from the sheet for being grasped by a user during installation of the sheet and its removal.
