    • A flexible laser safety curtain is disclosed that utilizes a plurality of columns flexibly attached to one another along their longitudinal edges in such a manner as to create a curtain of columns. The base of each column contains a cavity within which at least one moveable element, columnar in form, may be located and protrude from the cavity. The moveable element, when pressed against a work surface, is forced into the cavity. A biasing element within the cavity provides an opposite force on the moveable elements to both keep the moveable element in contact with the work surface, and to return the moveable element to its original position when the inward force is removed. The curtain's edge follows the contours of an uneven work surface and thereby the curtain provides a complete barrier to laser radiation.
    • 公开了一种灵活的激光安全帘幕,其利用沿其纵向边缘彼此柔性地附接的多个列,以便形成柱帘。 每列的基底包含空腔,在该空腔内至少有一个形状为圆柱形的可移动元件可以位于空腔内并从腔突出。 当可移动元件被压靠在工作表面上时,被迫进入空腔。 空腔内的偏置元件在可移动元件上提供相反的力,以将可移动元件保持与工作表面接触,并且当向内的力被移除时使可移动元件返回到其初始位置。 窗帘的边缘遵循不平坦的工作表面的轮廓,从而幕帘为激光辐射提供了完整的屏障。
