  • Patent number: 5415401
    Abstract: A movable body rebounding mechanism has a rocking plate, a plurality of projecting members and a rocking mechanism. The movable body rebounding mechanism is for use in amusement devices in which a movable body moves on an upper side of a game board having upper and lower sides. The projecting members project from the rocking plate to the lower side of the game board, through holes formed in the game board and out of the upper side of the game board. A clearance exists between the holes in the game board and the projecting members. The rocking mechanism reciprocates the rocking plate parallel to the game board in at least first and second directions. The rocking mechanism includes a drive mechanism for eccentrically rotating a first pin which projects through a hole in the rocking plate. There is little clearance between the first pin and the hole in the rocking plate. The drive mechanism further includes a second pin positioned stationary with respect to the game board.
