Abstract
A siren housing has a dish-shaped base having a back wall adapted to be secured to as support structure. The base is configured and dimensioned to contain siren components. A post projects forwardly from the back wall. The post has a cylindrical sidewall terminating at a front rim. At least one channel circumscribes a segment of the sidewall at a location spaced rearwardly from the front rim. Entry and exit slots communicate with the channel at spaced locations along the length thereof. The entry slot leads to the front rim and the exit slot leading towards the back wall. A dish-shaped cover has a front wall. A cylindrical sleeve projects rearwardly from the front wall, the sleeve having at least one pin projecting radially inwardly therefrom. The sleeve is dimensioned for axial insertion onto the post. The pin is arranged: to enter the channel via the entry slot; and to coact with the channel in supporting the cover above the base for movement between open and closed positions; and to exit the channel via the exit slot to accommodate seating of the closed cover on the base.
