  • Patent number: 6699099
    Abstract: A novelty article includes a base member, an elongated member mounted thereto and made of resiliently flexible material tending to assume an unrolled extended condition when unrestrained by an outside force and being manually rollable upon itself so as to bring opposite portions into contact with one another as the elongated member is rolled upon itself to a rolled-up compact condition, and elements on the elongated member for detachably attaching together the opposite portions thereof when brought into contact with one another such that upon release of the elongated member from the rolled-up compact condition these elements will detach from one another and concurrently generate a drag effect on the detaching of the opposite portions of the elongated member which limits the elongated member to undergoing a controlled progressive unrolling action from the rolled-up compact condition to the unrolled extended condition.

  • Patent number: 5219170
    Abstract: An action board game apparatus includes an inclined game board having openings therein, game pieces mountable on the game board partially through selected ones of the openings and capable of being pushed through the openings upon application of a sufficient predetermined force on an upper portion of each game piece extending above the game board, and a rotary driver movable across the game board. The driver has an elongated shaft and wheels attached to opposite shaft ends. The game board includes parallel linear tracks attached along opposite side edges of the board. The game board openings are arranged in parallel side-by-side rows also extending parallel to the guide tracks. The tracks receive the wheels and permit rolling movement to adapt the driver to move across the game board by itself with its shaft spaced above the game board and passing over upper portions of the game pieces.
