Abstract
A suction cup assembly has a vacuum release strap for detachment of the assembly from a recipient host surface on which the assembly is attached. The suction cup assembly includes a base adapted to be secured to an article to be supported, at least one flexible suction cup secured upright onto the base and a flexible release strap extending slack between the cup and the base. Tensioning of the strap causes a local deflection of the suction cup lip in a controlled direction from the recipient surface to release the vacuum holding force.
