The present invention is a releasable mounting device which includes a resilient layer or gasket (14) having a durometer rating of less than or equal to 30, shore A, and a suction cup (12) cooperating with the resilient layer for inducing a negative air pressure or suction between the resilient layer and a rough, or at least non-smooth, surface when the resilient layer (14) and suction cup (12) means are flattened against the rough surface, so that the resilient layer (14) is between the suction cup (12) and the rough surface, and released so as to remain releasably attached to the rough surface by reason of the negative air pressure or suction between the resilient layer and the rough surface. The suction cup (12) may be a conventional suction cup and the resilient layer (14) may be releasably secured by chemical bonding or otherwise to the lower surface, i.e., the concave contact surface, of the suction cup. The suction cup (12) alternatively may be any form of endo-frame or exo-frame secured or securable to the resilient layer (14) so long as the endo-frame or exo-frame (of which the conventional suction cup is an example) pulls the center portion or zone of the resilient layer (as opposed to its periphery) away from the rough surface so that the tendency of the center portion is to lift itself off the rough surface thereby inducing the negative air pressure or suction in the void or vacuum thereby formed between the center portion and the rough surface, the periphery of the resilient layer forming an air-impervious bond to the rough surface by reason of its soft resiliency. The resilient gasket may be made of cross-linked hydrated silicone polymer.
