ABSTRACT:
A movable shutter to be placed over an opening is made up essentially of horizontal sections, each of which sections comprise an intermediate section or filler of polycarbonate. A male extrusion is fixed to the filler at the top and a female extrusion at the bottom. This makes it possible to assemble the sections together. The shutter is guided by rollers carried by the sections. These rollers move in vertical guiding tracks fixed on the opening and continue on horizontal tracks mounted from the ceiling. The operation of the shutter is made easier by means of a compensation spring fixed above the opening. An anti-dislocation lock is mounted forcibly inside or attached onto two partitions of the female extrusion. When the ball and socket of a hinge are interlocked, the guide and the shoulder of the anti-dislocation lock are superimposed and their respective holes are aligned. Thus, after the roller axle is inserted in the aligned holes, the extrusions can no longer become dislocated whatever the angle of rotation of the hinge.
