Warehouse containing movable screen frames, uses springs to form friction coupling between screen frames and drive body with stroke length greater than distance travelled by each screen frame

摘要

The friction coupling between the screen frames and the drive body (15) used to move them between open and closed positions comprises springs, and the movement stroke for the drive body is greater than the standard length over which each screen frame is moved. The warehouse (1) comprises a frame assembled from columns (2), rafters (3) and gutters (4), and a number of screens that can be moved over a standard length distance between open and closed positions. Each screen has a cloth attached and is in frictional contact with at least one common drive body via a friction coupling to compensate for expansion and shrinkage forces, and/or inaccurate construction designs.
