Apparatus for suction mounting to a curved surface, such as a section of pipe, is disclosed. The apparatus is particularly suited for securing a container of industrial articles, such as tools and supplies, on a curved surface. The suction mounting apparatus includes a housing having a diaphragm assembly carried thereon. The diaphragm assembly includes a curved backing plate structure having a centralized opening therein to the interior of the housing. The assembly further includes a pad of pliable material disposed adjacent the backing plate and being of a configuration conforming to the periphery of the backing plate. The pad further includes an upstanding lip extending about its periphery, the lip being disposed in an overlapping relationship with the peripheral edge of the backing plate. A crankshaft is carried in the housing and connected to the diaphragm pad. Upon rotation of the crankshaft, a portion of the diaphragm pad proximate the opening in the backing plate is drawn upward, thereby creating a suction force that urges the backing plate toward the curved surface. A locking mechanism holds the crankshaft in position and maintains the suction force.
