    • A shutter assembly has a plurality of laths which extend between a pair of vertically extending side channels disposed to either side of a doorway, window or the like. A number of the laths are strengthened and are hollow box sections through which a pair of wire cables extend. The wire cables are anchored to retention members which can move vertically in the side channels. The remaining laths have windlocks at their ends which are located in and are moveable in the side channels. The wire strengthened laths are alternately interlaced with the remaining laths. The wire cables give additional strength to the strengthened laths and are sufficiently strong to withstand a heavy blow to the shutter assembly in the vicinity of the strengthened laths, extending with the blow and thereby absorbing energy rather than breaking.
    • 闸门组件具有多个板条,其在设置在门口,窗口等的任一侧的一对垂直延伸的侧通道之间延伸。 多个板条加强,并且是中空箱部分,一对电缆通过该部分延伸。 线缆锚固到可在侧面通道中垂直移动的保持构件。 剩余的板条在它们的端部具有位于并可在侧面通道中移动的端锁。 钢丝加强板条与剩余的板条交替交织。 电线电缆对加强的板条增加了强度,并且足够坚固,以承受在加强板条附近的闸门组件的重大冲击,随着吹风而延伸,从而吸收能量而不是断裂。

    • A roll-up, horizontally elongated, slat-type blind is formed of elongated slats which are hingedly connected together along their longitudinal edges. The slats are formed with upper flanges that are bent into downwardly opening flange hooks which extend into channels formed on the lower edges of the next adjacent slats. Each channel has an upwardly opening hook formed on one wall of the channel, and an opposite wall portion adjacent the hook. The flange hooks are notched at their opposite ends and the portions of the channel wall which overlap the notches are bent into tabs which extend inwardly to close the channel and to engage the opposite ends of the notches of the hook portions. Thus, the flange hooks are precluded from shifting endwise by the tabs to, thereby, maintain the slats in alignment at all times.
    • 卷起,水平伸长的板条型盲板由细长的板条形成,它们沿其纵向边缘铰接连接在一起。 板条形成有上凸缘,其弯曲成向下开口的凸缘钩,其延伸到形成在下一个相邻板条的下边缘上的通道中。 每个通道具有形成在通道的一个壁上的向上开口的钩和与钩相邻的相对的壁部分。 凸缘钩在其相对端处被切口,并且与凹口重叠的通道壁的部分弯曲成向内延伸的突片,以闭合通道并与钩部分的凹口的相对端接合。 因此,法兰钩不能被翼片端部移动,从而始终保持板条对准。
