Plunger, Mechanically Or Electrically Driven Patents (Class 273/129S)
  • Patent number: 5915693
    Abstract: 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.

  • Patent number: 5806851
    Abstract: An interactive play feature for a pinball game includes a shooting position on an inclined playfield and a target spaced apart from the shooting position. A shooting mechanism is responsive to input from a player for propelling a game ball from the shooting position toward the target. The game ball normally follows a path of travel from the shooting position to the target when propelled by the shooting mechanism. A blocking member is movable to a blocking position in response to the game ball reaching a desired position, wherein the blocking member obstructs the path of travel of the game ball to prevent the game ball from reaching the target.

  • Patent number: 5800288
    Abstract: A sport training apparatus for projecting a ball into the air for training an athlete in the proper technique of hitting or catching the ball. The apparatus includes ball projecting means and a spring connected thereto for movement between a cocked state and an actuated state. The spring is held in the cocked state by a partial vacuum automatically developed within an air chamber which is created when a piston enters a cylinder. To cock the apparatus for use, the ball projecting means is pushed down which, in turn, causes the piston to enter the cylinder and create the air chamber. A check valve is connected to the air chamber to provide unrestricted air exit from the air chamber as the piston enters the cylinder. A pneumatic control release is connected to the air chamber for allowing ambient air to enter the air chamber for releasing some or all of the partial vacuum to actuate the spring thereby causing the ball projecting means to propel the ball into the air where it can be hit or caught by the athlete.

  • Patent number: 5350174
    Abstract: The ball delivery system of the invention consists of a ramp located beneath the playfield where the ramp leads from an inlet accessible by the ball in play to at least one play feature to be loaded. At least one ball is stored in the ramp at each play feature such that the stored ball can be loaded into the play feature. A sensor located adjacent the inlet detects the entrance of the ball in play into the ramp and sends a signal to the game microprocessor indicating that a ball has entered the ramp. The microprocessor, upon receiving this signal, immediately loads the desired play feature with the stored ball such that the play feature can be immediately activated. The ball that entered the ramp inlet is then directed to the just activated play feature and becomes the stored ball for that play feature. Thus, the dead time associated with existing ball delivery system is eliminated.

Preferably, switches are provided for identifying to the electronic controls of the amusement device the discrete rotating position occupied by the rotatable member. Upon command, the temporary lock of the rotating positions may be released. A spring or the like then rotates the member back to an original, ball-receiving position upon such release, which propels the ball back onto the playfield with a velocity that depends on the particular discrete rotating position achieved.

    Abstract: A playing field board for pinball game machines which is assembled with a playing surface thereof inclined, and along the inclined playing surface of which a round ball rolls downwardly by gravity and is driven upwardly by means of kicker apparatus, is made of a steel sheet and a transparent plastic layer of synthetic resin, e.g. urethane, disposed on the surface of the steel sheet. Between the steel sheet and the plastic layer of synthetic resin comprising the playing field, a buffer such as paper sheeting is interposed to dampen the noises made by a ball rolling along the playing surface of the playing field. Such paper sheeting can be in the form of a sandwich of metal foil between two paper sheets. The steel sheet contains a hole which is located beneath the transparent layer of plastic, and the hole is filled by a transparent plug. A metal hole is welded to the underside of the steel sheet. The holder supports an electric light bulb which shines upward through the transparent layer of plastic.

  • Patent number: 4403440
    Abstract: A toy vehicle accelerator is disclosed which includes a housing, an opening in the housing of a width to fit a particular toy vehicle, and an impeller mounted to slide in the opening as well as to rotate freely in a horizontal plane. The impeller includes surfaces which contact a properly sized vehicle and permit the impeller to accelerate that vehicle. An improperly sized object merely causes the impeller to rotate, precluding the acceleration of such objects.

  • Patent number: 4391442
    Abstract: A gaming apparatus in which a roulette wheel has a circular rim and a downwardly converging frustoconical bowl contained within the rim and joined thereto forming a track therewith for a roulette ball and a rotatable wheel head centered within the bowl at the bottom thereof and formed with a plurality of numbered compartments for receiving the roulette ball. An automatic roulette ball spinner has a pair of guide tubes directed oppositely to one another and positioned along the rim for directing the ball tangentially onto the track. The guide tubes have a roulette ball magazine communicating therewith including respective powered plungers for propelling the ball through the guide tubes. The powered plungers are randomly activated and, in addition, the propelling force of the powered plungers is randomly adjusted. The plungers are actuated either electromagnetically or pneumatically.

An automatic roulette ball spinner having at least one guide tube is positioned along the rim for directing the roulette ball onto the track and is provided with a powered plunger for propelling the roulette ball through the guide tube. The guide tube is vertically moveable for lowering it onto the track to discharge the ball and then raising it to allow the ball to travel around the track uninterruptedly.

  • Patent number: 4295651
    Abstract: In a pinball-type game having a playing surface over which an object is propelled and an object feed and propulsion apparatus for propelling the object across the playing surface includes: a housing associated with said surface and an actuator member mounted on the housing. The actuator is capable of moving from a rest position to an actuated position and back again. When an object is located next to an object contact surface on the end of the actuator and the actuator moves from the actuated position back to the rest position the object is propelled across the playing surface.Mounted in the housing associated with the actuator is an object feed mechanism which is capable of simultaneously moving the object from a first position adjacent to the feed mechanism to a second position locating the object in an abutting relationship with the contact surface on the actuator as the actuator moves to its actuated position. To accomplish this the actuator is operatively connected to the feed mechanism.

  • Patent number: 4239220
    Abstract: A target game can be constructed utilizing a support member and a transparent housing or cover mounted on the support member so as to enclose an elongated, enlarged area. A target is movably mounted on a guide rail within this area so as to be capable of being moved between the ends of a path. A spring is located on the support member for moving the target from adjacent to one end of the path to adjacent to the other end. An escapement structure consisting of parts mounted on the support and on the target controls such movement so that the target member only moves incrementally each time it is engaged by a projectile. A shooting structure is pivotally mounted on the support so as to be accessible from the exterior of the housing. This shooting structure includes a hollow tube within which there is carried a plunger capable of being manipulated so as to shoot projectiles.
