ABSTRACT:
A suction cup release mechanism is described which includes a lever pivotally mounted to a support. A linkage member extends from the lever to a suction cup at a remote end of the support. The linkage member is secured to a peripheral edge of the suction cup. Upon the lever being pivoted, a force is exerted by the linkage member to draw the peripheral edge of the suction cup away from a surface to which it is adhering until suction maintaining the suction cup in position is released.
