Hinging-plate actuating system - has plate pivot bearings clear of their plane in overlapping rest position

摘要

The mounting and actuating system is for plates (1) in a row on beams (6) running along the row, and which swing together and overlap in the rest position. The pivot bearings (A, B) of the plates or the holders fitting round their edges are clear of the plane of the plates when in the rest position. The actuating pushrod (8) or rope engages with each at a point (C) near its edge (19) nearest the beam (6) in the rest position. ADVANTAGE - Low cost, easy installation, and requires little effort to operate.
