US Patent 7536836 Removable ceiling panel

The invention relates to a removable ceiling panel, a rectangular material with a face, a back and four sides with edges, installed from beneath and retained horizontally by its four sides, concealing the profiled suspension grid. The panel is supported at the four sides and it is retained by gravity in the vertical direction. The profiled suspension grid is of the standard type known in the market. The design of the sides of the panel permits carrying out its installation on the basis of simple precise movements, which procedure for installation also forms part of the patent applied for. Said installation movements are not natural and, consequently, render the panels aseismic.
