    • An improvement in a rolling shutter assembly for covering an opening of a structure defined by a top wall, a bottom wall and oppositely disposed side walls. The rolling shutter assembly includes a shutter housing, a shutter support member rotatably disposed within the shutter housing, a shutter coupled to the shutter support member, the shutter comprising a plurality of individual slats and a plurality of hinges interconnecting the slats, and a pair of side tracks. The shutter rolls between a rolled position wherein the shutter is rolled onto the shutter support member and an unrolled position wherein the shutter covers the opening and the ends of the slats are disposed within the channels of the corresponding side tracks. The improvement comprises a support frame having top, bottom and side rails mounted to the walls defining the opening with the side tracks each mounted to a corresponding one of the side rails of the support frame. The support frame reduces or eliminates the transmission of torsion loads from the shutter to the framing elements of the walls during positive and negative pressure conditions.
    • 用于覆盖由顶壁,底壁和相对设置的侧壁限定的结构的开口的滚动快门组件的改进。 滚动快门组件包括快门壳体,可旋转地设置在活门壳体内的活门支撑构件,联接到活门支撑构件的活门,活门包括多个单独的板条和互连板条的多个铰链,以及一对 侧轨。 快门在其中快门滚动到快门支撑部件上的滚动位置和其中快门覆盖开口的开卷位置之间滚动,并且板条的端部设置在相应侧轨道的通道内。 该改进包括支撑框架,其具有安装到限定开口的壁的顶部,底部和侧部轨道,侧壁轨道各自安装到支撑框架的相应的一个侧轨。 在正压和负压条件下,支撑框架减少或消除了从闸门到墙壁的框架元件的扭转载荷的传递。
