Abstract: A bowling game variation of the game of bingo bowling is provided which allows for a bowling game wherein the bowlers can eliminate the “race” element of the game, and instead, play a bingo bowling game with scoring points being awarded. According to the invention, the bowler is given a set of shot or frame outcomes to achieve, and is awarded points based on the completion of the shot or frame outcomes within a pre-set time period or within a pre-set number of frames. Scoring for the card can be accomplished using a computer based system. This system allows for a wider variety of games to be played by a bowler.

Abstract: A rolling security shutter system is provided with improved structure for resolving security, alignment and tracking problems in rolling shutters employing an interconnected set of slats. Problems of insecure mounting and interfitting of housing assembly elements precisely enough that there is no misalignment or binding of the slats as the shutter is opened and closed are resolved inpart by integrally cast single element sideframes mounted by means of mounting bars interfitting into integrated guided slot brackets. The slats are guided into alignment with the tracks by means of frictionally inserted guides held by the sideplates. Connection of slats to the roller core by a flexible spring panel improves salt to track alignment and security against forced entry. Hood strengthening support structural mounts register housing members for better slot alignment and strength and ease of dismount. Improved spring clip slat reinforcement bar retainers assure slat rigidity and alignment.

Abstract: A shutter assembly is made of adjacent interlocked extruded plastic slats having a hollow generally rectangular body with extending tongue and channel interlocking members. Provision is made for locking slats in mated position against longitudinal movement and for a metallic end bearing surface providing long wear under heavy use.The slat structure is ribbed to remove rain water that may tend to pass through a shutter and for adding strength and can receive strengthening rods as desired in a mating internal female cell structure.
