A suction cup adapted to couple objects to rough surfaces includes a flexible sealing member, a backing member and a release mechanism. The sealing member is placed flush against a rough surface to form a low pressure region therebetween. The backing member is coupled to the sealing member and pulls a central portion of the sealing member away from the rough surface to create a suction hold. The release mechanism diminishes this suction hold when activated by a user. The sealing member material has a durometer rating of less than about 50, shore A. A rigid outer shell disposed above the sealing and backing members includes a rim to facilitate seal creation between the sealing member and the rough surface, and houses a portion of the release mechanism, which can include a button or lever adapted to push or pull the backing member toward or away from the rough surface. |
