Abstract:
A closure for fire truck water ports comprising:a body having an upper surface, a lower portion having internal threads, and a pair of handles extending from opposite sides of the body; wherein the upper surface has a recessed central area with a central face; a display plate rotatably mounted within the recessed area; a spring in the form of sponge foam material is placed between the central face of the recessed area and the rear surface of the display plate; and an O-ring for inhibiting the rotating of the display plate and for retaining the display within the body; the o-ring is mounted within the recessed area such that the spring forces the display plate against the o-ring in a non-rotating orientation; and wherein the plate is allowed to rotate when a force is applied to the upper surface of the plate thereby depressing the foam spring and disengaging the plate from the O-ring thereby allowing the plate to freely rotate with the recessed area to place the display plate in an upright orientation.
