A novel suction cup mounting apparatus having a novel compact axial suction cup installation and release mechanism and method for assembling such a suction cup apparatus. The suction cup device includes a suction cup portion of a plunger assembly fit within a concave drive base and coupled thereto by a rigid drive pin. An optional rotational drive member or “handle” structured to operate on an external surface of the drive base may be provided for manipulating the drive pin relative to the suction cup and drive base. The suction cup device is intended to secure some device—a “utilization device”—to a surface. Therefore, according to another aspect of the suction cup device, a utilization mounting surface is projected above the drive base.
