<p>PURPOSE:To obtain a safe and inexpensive panel mounting device by a method wherein a panel is constituted so as to be unable to be opened otherwise the panel under closed condition is elevated. CONSTITUTION:A panel 2 is slid toward the base end 2a thereof under a condition that the tip end 2b of the panel 2 under closed condition is elevated to release the tip end side projection 42 of a frame body from the retaining vertical groove 52a of the tip end side engaging piece 52 of the panel 2 through a notch 51b for attaching and/or detaching whereby hooking of the tip end engaging piece 52 to the tip end side projection 42 can be released. Next, the tip end 2b side of the panel 2 is pivoted downward about the base end 2a side whereby the panel 2 can be opened under vertical condition substantially. Under a condition that the tip end side 2b of the panel 2 is not elevated, the hooking of the tip end side engaging piece 52 can not be released. In this case, the panel 2 can not be opened also. According to this method, unnecessary opening of the panel 2 due to mistaken detaching operation can be prevented.</p> |
