Abstract: An aperture, covering including track-guided interconnectable panels that are compactly stored in a storage area containing weight counterbalancing mechanisms, such as a compressed spring, is described. When the panels are stacked in the storage area and removed one at a time, the first panel is removed from the storage area and enters the track. As the first panel moves through the track, it interlocks with the second panel and forces the second panel out of the storage area and into the track. Interlocking and removal of the panels continues until all of the panels are removed or the first panel reaches the end of the track. Weight counterbalancing can be assisted by track-contained mating mechanisms, cable and ball drive mechanisms, or other counterbalancing methods. The resulting aperture covering requires minimal storage space for the open aperture position, minimizes exposure to potentially hazardous counterbalancing mechanisms, and allows for heavy-weight panel construction.

Abstract: The present invention is directed to a modular roll-up partition assembly, such as a rolling protective shutter, implementing an improved tension adjustment mechanism for torsion springs used in roll-up partition assemblies. In one embodiment, the roll-up partition assembly of the present invention includes a tension adjustment mechanism to adjust the tension of a torsion spring connected between a support rod and the partition support member. The tension adjustment mechanism rotates the support rod to move the end of the torsion spring connected to the rod relative to the end of the torsion spring connected to the partition support member. Unlike previous roll-up partition assemblies which permitted adjustment of the torsion spring tension only in increments of a full rotation of the support member, the tension adjustment mechanism facilitates fine adjustment of the torsion spring in increments of less than a full rotation of the partition support member.

Abstract: The instant invention is an apparatus for maintaining approximately constant tension of a curtain between a drive roller and a storage roller. The constant tension is achieved by pre-tensioning the curtain between the drive roller and the storage roller and then maintaining approximately the same amount of tension by rotating the reference to which one end of a spring is attached. The rotating reference is a shaft which is affixed to and rotates with a shaft gear. The other end of the spring is affixed to a cylindrical tube member, i.e., the storage roller, upon which the flexible curtain is stored. A motor driven gear drives a gear affixed to the drive roller. The gear affixed to the drive roller in turn drives idler gears which in turn drive the shaft gear. A method of using the apparatus is also disclosed.

Abstract: A method and apparatus according to various aspects of the present invention is configured to automatically reset a rollable fire door curtain in the raised position. In one embodiment, a brake is coupled to a rolling fire door axle by an electromechanical clutch. The fire door is pre-disposed to unroll and close the opening, however, the brake prevents the door from unrolling. When a switch, a signal, or a fusible link indicates that the fire door should close, an electromechanical circuit board sends an electrical signal to an electromechanical clutch which opens the clutch. With the clutch open, the brake is no longer coupled to the fire door and the door closes. When the switch or signal is reversed, the clutch closes, re-coupling the fire door axle to the brake. The brake allows input rotation in both directions, but prevents the rolling door from closing under its own weight. Therefore, upon raising the curtain, the fire door is automatically reset and ready to close in the event of a fire.

In the closed position, the lower slat rests against a horizontal surface and the slats are interlocked with one another along their length to form a continuous sheet. In the partially or fully opened position, the slats are disengaged and separated from each other by a space determined by the height of the hooking system (7).

The alignment/retention members engage the adjoining slats to prevent substantial relative movement of the interconnected slats, and are dimensioned so that the alignment/retention members do not extend beyond the surfaces of the slats.
