Abstract: 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 mounted to the cabinet, and a backbox extending upwardly from a rear portion of the cabinet. To facilitate modification of electronics controlling the operation of the pinball machine, a controller box assembly is installed in the backbox. The controller box assembly comprises a rail structure mounted within the backbox and a controller box movably mounted relative to the rail structure to open and close the controller box. The controller box containing the electronics may be pivoted downwardly while remaining in engagement with the rail structure to provide easy access into the controller box.

Abstract: 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. One of these features is a novel playfield assembly for the pinball machine. For ease of movement of the playfield into and from a cabinet of the pinball machine, the playfield has skid rails which extend substantially along the length of the playfield. The skid rails are spaced from the lower side of the playfield by a distance that is greater than the distance by which components protrude from the lower side of the playfield. Thus, the playfield can be placed on the ground without any chance for damage of its components. The playfield may also include a slide stop at one or both of its ends. The slide stops engage the front molding of the cabinet to ensure the playfield does not fall into the cabinet or fall from the cabinet as the skid rails are being slid across the front molding.

Abstract: A pinball machine has been designed with several novel mechanical and electrical features such that it is easily serviceable and is easily retrofittable or convertible between a first pinball game and a second pinball game. One of these features is a novel mounting mechanism for a playfield of the pinball machine. The pinball machine includes a cabinet to which the playfield is mounted. The cabinet includes slides rails having notches for mating with corresponding pieces of the playfield thereby permitting easy rotation of the playfield within the cabinet during servicing or game conversion. Thus, the electronics and mechanical components below the playfield can be readily accessed.

Abstract: 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.

Abstract: 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 playfield mounted to a cabinet. Unlike previous pinball machines, electrical wires and their associated "playfield-side" connectors extending from input/output elements mounted to the playfield are limited in movement to a region generally beneath and in close proximity to the playfield. This allows the playfield to be more easily handled than prior playfields, which had long dangling electrical wires and connectors which could be easily tripped over or severed. Additionally, the plurality of playfield-side connectors are configured for easy installation and integration with corresponding "cabinet-side" connectors.

Abstract: A pinball game playfield feature includes a circular table which is rotated by a motor and linkage. Mounted on the table is a target housing having optical emitters disposed therein. Optical detectors are located in the table. Each emitter-detector pair forms a light beam which can be interrupted by a pinball to signal the game microprocessor for scoring or other purposes. Rotation of the table permits selectable positioning of the optical target bank.

Abstract: The present invention is a computer-controlled interactive playfield feature for pinball games. The system microprocessor monitors activity on the playfield and controls the interactive playfield feature, directing the player's attention to specific targets and activities on the playfield. The playfield feature operates in conjunction with a speech synthesizer, which may be programmed to taunt and challenge game player, increasing player appeal. In a preferred embodiment, the interactive playfield feature is in the shape of a jocular human head. The mouth, eyelids and eyes are movable under microprocessor control. The mouth serves as a ball target. When the player successfully shoots the ball in the mouth, a solenoid ball ejector returns the ball to the playfield. The eyes may be programmed to follow the travel of the pinball on the playfield.

Abstract: A ball diverting playfield feature for pinball games employs a pair of abutting surfaces disposed on or above the playfield, which can be separated to create an alternate ball path. A solenoid mechanism controls the positions of the surfaces.

Abstract: A game cabinet for pinball machines including a horizontal and vertical playfield comprises a horizontal case for the horizontal playfield and a vertical case for the vertical playfield.

Abstract: A three-dimensional game having rotatable track members mounted on a support frame on which a self-propelled vehicle may be guided over a predetermined course through rotation of the track members. The track members are mounted on the support frame so that they can be rotated into a plurality of positions in some of which positions a set of track members forms a substantially continuous path upon which the vehicle may travel from one track member to another track member. Rotation of the track members is accomplished through manipulation of a set of attached knobs. Each track member may include a metal panel to which the magnetized wheels of the self-propelled vehicle are attracted, allowing for rotation of a vehicle-carrying track member in a full circle without the vehicle falling from the track member.

Abstract: A toy motorcycle is mounted on and supported by a front wheel and a driven rear wheel which is heavy enough to act as a flywheel. A pull string mechanism includes a spring biased spring spool having a gear, with a step-up gear train imposed between the spool gear and the rear driven wheel. A centrifugally operated pawl mechanism is driven by the gear train to couple with ratchet teeth formed on the rear wheel in order to drive the rear wheel in one direction and to decouple from the ratchet teeth when the gear train is driven in the opposite direction during string recoil. The rear wheel has a greater moment of inertia than the other components of the pull string drive mechanism to enable the rear wheel to function as a flywheel and thereby store energy to drive the motorcycle. A reed is positioned to be plucked by a rotating cam to produce sound.

Abstract: An optical position location apparatus for locating the position of an object in one or more dimensions, which relies upon one or more sources of radiant energy and distributor devices to disburse such radiant energy over a location region or window. Integrated collector assemblies positioned opposite to the distributors receive and collect the transmission of the distributed radiant energy and through reflection or refraction, transfer radiant energy to a minimum of detection locations to monitor the absence or alteration thereof. A rotating optical scanner and a detector are utilized with a continuous stationary light source to successively monitor specific location-coordinate-related portions of transmitted radiant energy and through electronic circuitry, a signal is developed to disclose, with accuracy, the location of objects within the location region "window", as well as other parameters including object size.

The launchable balloon is mounted on the torso under tension and sealed against air leakage. The trigger releases the balloon and launches it when it is struck by the fist of an opposing boxer.

Abstract: A board game including a number of generally similar rectangular tiles slidable relative to one another on a base to form a rectangular pattern with at least one vacant space equal in size to a tile. At least one groove is formed in the top surface of some of the tiles and more than one groove is formed in the top surfaces of others of the tiles with each groove extending from one side edge of a tile to another side edge of a tile. All grooves intersect the side edges of its tile at the midpoint of each side edge so that continuous paths can be formed on adjacent tiles if each adjacent tile has a groove extending to its side edges that is contiguous to an adjacent tile. Discontinuous paths are formed if one of the tiles does not have a groove extending to its side edge that is contiguous with an adjacent tile. A self-propelled vehicle is provided to move across the tiles. The vehicle has a guide which rides in the groove to direct the vehicle across the tile.

Abstract: A hand-held electronic game which uses a two-way mirror arrangement to simulate the battle between the player's rocket ship protected by barriers and a plethora of enemy rocket ships. The enemy rocket ships and the barriers are affixed on two parallel, spaced apart, vertical planes. Apertures in the front plane give the impression in the two-way mirror that the devices on the different planes are all in the same plane. In addition, the player's rocketship and death ray, on a horizontal plane, are also projected on the two-way mirror so that it appears that all the devices are in a single plane.
