摘要： A lock-down bar release system for a pinball machine serviceable in a location-service mode and an operator-service mode. The pinball machine includes a playfield disposed within a game cabinet and a lock-down bar for securing a playfield glass over the playfield and onto the game cabinet. A handle mechanism and associated latching structure is operable to release the lock-down bar. In the location-service mode, the movement of the handle and release of the lock-down bar is effected automatically by using a location-service key. In the operator-service mode, the operator uses an operator-service key to access the interior of the game cabinet through a coin door from wherein the operator may physically pull the handle to release the lock-down bar. The pinball machine includes a restraint mechanism for inhibiting removal of the playfield (and thereby preventing access to the coin box or cash box under the playfield) in the location-service mode. The restraint mechanism moves to a non-blocking position when the coin door is opened in the operator-service mode so as to permit removal of the playfield in the operator-service mode.

摘要： A pinball machine has been designed with several novel mechanical and electrical features such that it is easily retrofittable or convertible between a first pinball game and a second pinball game. The pinball machine includes a cabinet, a playfield, a playfield panel, an electronics system, and a video display. The playfield is mounted in the cabinet with the playfield panel mounted to the cabinet and overlaying at least a portion of the playfield. The video display is mounted generally above the cabinet and is disposed to project video images onto the playfield panel for viewing by the player. When the pinball machine is retrofitted, diagnostics can be performed while the playfield panel is still removed from the pinball machine by displaying diagnostic video images/information onto a partially reflective member positioned below the video display. The partially reflective member may, for example, be the glass or plastic structure that is mounted on the backbox and acts as the marquee for the pinball machine.

摘要： An improved golf club shaft and golf club, the shaft being of stepped configuration, having a uniform outer diameter butt end portion having a uniform wall thickness at least 10 inches (254mm) long, the uniform wall thickness being not greater than 0.012 (0.305mm) and a plurality of cylindrical step portions of progressively smaller outer diameter terminating in a tapered tip end portion having a wall thickness at the tip end of at least 0.024 (0.610)mm). The shaft is characterized by a redistribution of metal which results in a balance point closer toward the tip of the shaft, making it possible to use a lighter head without affecting the swing weight.

摘要： A game ball cradle is positioned upon the playfield of a pinball game. A player-controlled solenoid plunger mechanism "pops" a ball positioned within the cradle into the air. A wire form jump rope is rotatably connected to an electric motor. The jump rope is positioned so that when it is rotated, it will pass under a game ball that has been properly "popped" by the player. A switch indicates to the game microprocessor that the jump rope has completed a revolution. Optical detectors indicate to the game microprocessor that the game ball is within the cradle so that the electric motor may be activated and, upon completion of a successful "jump", the player's score incremented and the speed of the jump rope rotation increased.

摘要： A play feature for a pinball game features a multimode target with a variable trajectory ball ramp. The multimode target features a pair of distinct targets mounted upon the playfield of the pinball game in a rotating fashion. The multimode target may be rotated between positions whereby each of the distinct targets is exclusively accessible by the game ball thus providing the pinball game with more than one mode of play. A variable trajectory ball ramp is positioned upon the playfield and is curved and banked towards the multimode target. A pinball properly negotiating the ramp may strike the multimode target so as to increase the player's score. The multimode target may oscillate and the distinct targets may feature a number of sub-targets as well as oscillating barriers.

摘要： The jet bumper of the invention consists of a body mounted to the playfield. A solenoid actuator and rebound ring are mounted on the body. An eddy current sensor is disposed about the body to detect the approach of a ball. Upon detection of the ball, the eddy current sensor energizes the solenoid actuator to retract the rebound ring and propel the ball.
