Abstract:
A new and improved security lock for a door situated within first and second parallel door frames, each of said door frames having first and second sides, comprising:a door having a given width and having first and second sides, and having a key-actuated lock useable from said first side of the door; a cross-bar brace having a length in excess of the width of said door, wherein the first end of brace is pivotally connected to the first side of the first door frame, and the second end of the brace being latchable with a brace mounted vertically on the first side of said second door frame; a locking mechanism integrally positioned relative to the lock comprising a housing mounted to the second side of the door and a holder for removably entrapping the brace, whereby the rotation of the key-actuated lock vertically maneuvers the holder relative to the housing; the housing further comprises an integral U-shaped sleeve for receiving the holder and brace; whereby the holder includes a top flange for receiving the brace thereunder, whereby the flange inhibits the vertical motion of the brace; and whereby the rotation of the key-actuated lock in a first direction causes the holder and brace to be latched within the sleeve, and the rotation of said key-actuated lock in a second direction causes said holder and brace to be unlatched from the sleeve.
