The feet are attached to a pair of tilting base mounting assemblies each having a base housing component in the shape of an elongated box shaped housing to be fixed to the roof and having a tiltable top plate member pivoted to the box-shaped housing for movement from a first position disposing the arch member in a raised normal operating position to a second position disposing the arch member in a lower position wherein the leg portions lie substantially parallel to the roof. Powered actuator means in the box-shaped housing controlled by a toggle switch move the top plate member between the first and second portion.
