ABSTRACT:
A suction cup assembly is provided for securing a utilization device to a surface. The suction cup assembly includes a suction cup and a core member. The core member has a generally cylindrical outer surface, and is secured to the suction cup. The assembly also has a cone member which has an outer periphery generally co-extensive with the outer portion of the suction cup, and which has a generally cylindrical inner opening closely enclosing the cylindrical outer surface of the core member. The cone member and the core member constitute a pair of mating members. The assembly further includes a cam member for axially shifting the core member outward relative to the cone member by pulling the center of the suction cup away from a surface to which the suction cup may be adhered. The cam member has generally cylindrical camming surfaces, and is mounted onto and closely engages either the core member or a camming flange on the cone member, depending on the embodiment.
