Abstract:

An obstruction device for the purpose of securing a hatch or window opening from the interior on a room, using shutter slats hingedly mounted and vertically hung to the track on the inside edge of the shutter frame; horizontal members are fixed to the back of the frame near the top and bottom, and continuous from one side to the other to obstruct the shutters from swinging outwardly: the shutter frame is slotted continuously from one side of the frame to the other side and along a small portion of the inside edge in the four corners in the top and bottom: top and bottom horizontal sliding members are fitted into the said top and bottom sliding spaces and extend into slots of opposing corners so as to allow them to slide up and down in said slotted spaces but remain in the slots in opposing corners: Strong flexible straps attached to both ends of a bottom horizontal sliding member, are routed up over the rounded ends of spacer blocks and down the other side where it is attached to the ends of vertical sliding members; said vertical sliding members extend within vertical hollow spaces in both sides of the frame from the bottom of the frame to the top horizontal sliding member where they are firmly attached. When the shutter slats are extended to close the opening, and the top and bottom horizontal sliding members are in the obstructive locking position, a locking pin is inserted through either or both sides of the shutter frame to penetrate the vertical sliding members.
