Abstract
A security shutter resistant to forced entry comprising a fixed frame and panels.

The locking elements are moved by rods and connected to levers which are unitary with control bars. The shutter is resistant to break-ins.
Claims14
Closing system of the type comprising at least one set of panels which comprises a plurality of panels, of which one is an affixed panel movably mounted to a fixed frame, and the furthermost panel from the affixed panel within the same set being an end panel adapted for engagement to a fixed frame or to another end panel, said panels being connected to each other by joints, the panels having an upper and lower free extremity, at least one panel of each set having two respectively upper and lower rims, the closing system comprising two locking elements for the closed system which are positioned in the vicinity of the free extremities of the panels and which are movably mounted relative to the frame between an active position in which they cooperate with all of the deployed panels to make them unitary with the frame and a retracted position in which they leave all the panels free, means being provided for locking the two elements in the active position, each of the upper and lower rims being placed against a portion of the frame which is continuous and parallel to the aligned rims of the deployed panels and the locking element which, in its active position, straddles simultaneously all the aligned upper rims and a portion of the frame whereas the other locking element in its active position straddles simultaneously all the aligned lower rims and another portion of the frame.
Closing system of the type comprising two sets of panels which comprises a plurality of panels, of which one is an affixed panel movably mounted to one side of a fixed frame, the furthermost panel from the affixed panel within the same set being an end panel adapted for engagement to the opposite side of the fixed frame, the end panels engaging when all the panels are deployed, said panels being connected to each other by joints, the panels having an upper and lower free extremity, at least one panel of each set having an upper and lower rim, the free edge of one of the two end panels penetrating between two rims respectively internal and external provided upon the other end panel parallel to the plane of panels, the closing system comprising two locking elements for the closed system which are positioned in the vicinity of the free extremities of the panels and which are movably mounted relative to the frame between an active position in which they cooperate with all of the deployed panels to make them unitary with the frame and a retracted position in which they leave all the panels free, means being provided for locking the two elements in the active position.
Closing system of the type comprising at least one set of panels which comprises a plurality of panels, of which one is an affixed panel movably mounted to a fixed frame, the furthermost panel from the affixed panel within the same set being an end panel adapted for engagement to a fixed frame or to another end panel, said panels being connected to each other by joints, the panels having an upper and lower free extremity, at least one panel of each set having an upper and lower rim, the closing system comprising two locking elements for the closed system which are positioned in the vicinity of the free extremities of the panels and which are movably mounted relative to the frame between an active position in which they cooperate with all of the deployed panels to make them unitary with the frame and a retracted position in which they leave all the panels free, means being provided for locking the two elements in the active positions and control means for simultaneously moving the two locking elements between said active and retracted positions.
