<p>A plane grating (100) composed of grating doors (10, 20) capable of sliding on the same rail. In the plane grating (100), the grating doors (10, 20) are constituted of lateral bars (12, 22) substantially parallel to the rail and at least one vertical bar (14, 16, 24, 26). The lateral bars (12, 22) of the adjacent grating doors form pairs by receiving lateral bars (12A, 22A) and to-be-received lateral bars (12B, 22B), and the receiving lateral bars (12A, 22A) are hollow and are capable of receiving the to-be-received lateral bars (12B, 22B). The structure above enables the grating doors (10, 20) to be slid on the same rail to open the plane grating. Therefore, the plane grating can be thinned and reduced in weight, and can be relatively easily installed on an existing sash etc.</p> |
