Security device for buildings

A security device for releasably blocking a doorway or window opening of a building structure, said device comprising:

• a sturdy, continuous, metal frame configured to fit within an interior perimeter of the doorway or window opening, said frame defining an interior frame opening bounded on at least two opposing sides by first and second frame members which are substantially contiguous with sides of the doorway or window opening when in a secured position;
• a security grid extending across and covering the interior frame opening and being anchored to the metal frame to form a single structure;
• at least one mounting plate coupled to the continuous metal frame and security grid and extending into the interior frame opening;
• a first guide tab securely attached to the mounting plate and extending outward therefrom;
• a second guide tab securely attached to the first frame member and extending outward therefrom;
• a third guide tab securely attached to the mounting plate and extending outward therefrom;
• a fourth guide tab securely attached to the second frame member and extending outward therefrom, each of said guide tabs including a guide track opening configured to slidably receive a locking bar;
• and
• first and second locking bars, the first locking bar journalled within the first and second guide tabs and the second locking bar journalled within the third and fourth guide tabs, said first and second locking bars having first and second perimeter locking ends add first and second interior locking ends, respectively, each of said perimeter locking ends configured for slidable entry into receiving slots formed in the interior perimeter of the window or door opening,
• said first and second interior locking ends respectively including first and second means for releasably interlocking with the at least one mounting plate when their respective locking bar is seated within a receiving slot in the interior perimeter to retain the metal frame in a secured position.

A security device for releasably blocking a doorway or window opening of a building structure, said device comprising:

• a sturdy, continuous, metal frame configured to fit within an interior perimeter of the doorway or window opening, said frame defining an interior frame opening bounded on at least two opposing sides by first and second frame members which are substantially contiguous with sides of the doorway or window opening when in a secured position;
• a security grid extending across and covering the interior frame opening and being anchored to the metal frame to form a single structure;
• at least one positioning bar disposed on the second frame member and configured for placing into a receiving slot formed in the interior perimeter of the window or door opening;
• and
• a locking bolt slidably disposed on the first frame member and having at least one perimeter locking end configured for slidable entry into a receiving slot formed in the interior perimeter of the window or door opening, wherein the locking bolt comprises a threaded interior locking end, and wherein the perimeter locking end of the locking bolt is unthreaded;
• means for releasably restraining said locking bar from movement relative to the metal frame when said locking bar is seated within the receiving slot in the interior perimeter to retain said metal frame in a secured position, said means including a threaded slot formed in the first frame member and positioned adjacently collinear with the receiving slot of the interior perimeter of the window or door opening when the frame is placed therein, the locking bolt releasably screwable into said threaded slot such that the perimeter locking end of said bolt enters said receiving slot to thereby secure said locking bolt within the first frame member.
