发明名称 SHEET METAL SNAP-UP PAN FOR SUSPENDED CEILING
摘要 <p>A snap-up panel for suspension ceiling systems is disclosed. The panel is formed of sheet metal and provides a central planar section and four upwardly extending flanges along the edges of the planar section. Each flange is formed with an inwardly directed rib extending along the length of the flange at a point spaced from the upper and lower edges thereof. Detents are provided in the flanges adjacent to the corners and are positioned in alignment with the ribs and sized to project beyond the inner extremity of the ribs. These detents provide additional support for the panel when the ribs are snapped over supporting lips in a suspension ceiling grid system. Improved alignment and support of the panels are provided by the detents when the panels are installed in a suspension ceiling grid.</p>
