## Background
FIELD OF THE INVENTION
The present invention relates to a hand-held pinball game. More particularly, the present invention relates to a hand-held pinball game having a changeable display. Still more particularly, the present invention relates to a hand-held pinball game having a changeable display and an impact sensor that changes the path of a simulated pinball during play. The hand-held pinball game has a removable display card that may be replaced with another display card to change the image viewable through a display screen of the game.
BACKGROUND OF THE INVENTION
Hand-held electronic games have been widely popular toys since their introduction. These games provide portable versions of favorite games previously found only in arcades or at home on a personal computer or video game system. The ease of use and the portability of hand-held electronic games provide enjoyment to a wide range of electronic game players.
Hand-held electronic pinball games are one of many popular hand-held electronic games. Advances in electronic technology have allowed these hand-held electronic pinball games to closely simulate the original stand-up pinball games, thereby allowing pinball fans to play whenever and wherever they want.
One problem with existing hand-held electronic pinball games is the inability to change the display image of the game. With stand-up pinball games, when players become tired of playing a particular machine they can simply move to another stand-up pinball game and continue playing on the new machine. However, existing hand-held electronic pinball games are not so versatile as to allow players to change the display of the game to essentially create a brand new game. If a player becomes tired of a certain game, they must either have another hand-held electronic pinball game available or stop playing. A need exists for a hand-held pinball game in which a player may change the display.
Stand-up pinball games allow a player to shake or move the pinball game, within reason, to change the path of the pinball. A “tilt” generally occurs if the stand-up pinball game is either moved too much or too violently. Another problem with existing hand-held electronic pinball games is not being able to change the path of the ball through movement of the hand-held game as can be done with stand-up pinball games. A need exists for a hand-held pinball game in which a player may change the path of the simulated pinball by tapping or nudging the housing of the game, and which includes a tilt feature to prevent over-use of the tapping feature.
Existing handheld pinball games do not have changeable displays. U.S. Pat. No. 4,334,679 to Doyle et al. discloses a hand-held pinball game having LED's that are energized to simulate a pinball and flippers and a speaker to provide pinball sounds. U.S. Pat. No. 4,253,090 to Storie et al. discloses a plunger for a hand-held electronic pinball game. U.S. Pat. No. 6,612,573 to Klitsner et al. discloses an electronic hand-held game having user manipulated controls for controlling the direction and power of a simulated launched object.
A need exists for an improved hand-held pinball game having a changeable display.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide an improved hand-held pinball game.
Accordingly, another object of the present invention is to provide a hand-held pinball game having a changeable display.
Accordingly, another object of the present invention is to provide a hand-held pinball game having a tap or nudge feature to allow a player to change the path of the simulated pinball.
The foregoing objects are basically attained by providing a hand-held pinball game having a changeable display. The pinball game has a housing having a front face. A display screen is formed in the front face of the housing. A first opening is formed in the housing. A display card is visible through the display screen. The display card is insertable and removable through the first opening. A second opening in the housing receives additional display cards so that the pinball game display may be changed by the player. An impact sensor in the housing allows the player to nudge the housing to change the path of the simulated pinball.
The foregoing objects are also attained by providing a method of playing a hand-held pinball game.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1-12, a hand-held pinball game 11 has a changeable display 13. The hand-held pinball game 11 has a housing 21 having a front face 23. A display screen 31 is formed in the front face 23 of the housing 21. A first opening 41 in the housing 21 receives a first display card 51, which is visible through the display screen 31. The first display card 51 is insertable and removable through the first opening 41. A second opening 43 in the housing receives a second display card 53 so that the pinball game display 13 may be changed by a player. An impact sensor 61 in the housing 21 allows the player to nudge or tap the housing 21 to change the path of the simulated pinball 71.
The housing 21, as shown in FIGS. 1-3, has a front face 23 and a back face 24. Top face 25 extends between top edges of the front and back faces. Bottom face 26 extends between bottom edges of the front and back faces. Side faces 27 and 28 extend between side edges of the front and back faces. Preferably, the housing 21 is made of plastic.
A display 13 is formed in the front face 23 of the housing 21, as shown in FIGS. 1 and 11. The display 13 includes a display screen 31, which is preferably an LCD, as shown in FIG. 12. The display screen 31 has a dot-matrix portion 33 for displaying animations and text. The display screen 31 also has a plurality of pinball segments 35 that are energized to correspond to various positions of the simulated pinball 71, as well as a plurality of plunger segments 36 and a plurality of flipper segments 37 corresponding to left and right flippers 72 and 73. The pinball segments 35 are sequentially energized to depict the path of the pinball 71 throughout the display screen 31. The pinball segment 35 corresponding to the precise location of the simulated pinball 71 at that instant is energized to show the location of the pinball, which in FIG. 12 is shown as just having been launched. A plurality of plunger segments 36 are energized depending on the amount of power to be given to the simulated pinball 71 at launch. The more plunger segments 36 that are de-energized at launch, i.e., the fewer plunger segments that are visible, the more power that is to be provided to the simulated pinball 71 at launch. Conversely, the fewer plunger segments 36 that are de-energized, i.e., the more plunger segments that are visible, the less power that is to be supplied to the simulated pinball 71 at launch.
A first display card 51 is disposed behind the display screen 31, and is visible through the display screen, as shown in FIG. 11. The first display card 51 is imprinted with graphics viewable through the display screen 31. Preferably, the first display card 51 is substantially planar. A tab 57 extending from the bottom edge 56 of the first display card has an opening in a position to allow completion of a circuit when a contact is allowed to touch specific locations on the PC board. The processor will activate a specific game depending on the electrical path completed that is exclusive to that card. The tab 57 of the first display card 51 interacts with the printed circuit board 81 to enable features of play exclusive to that display card. A second display card 53 has substantially the same overall shape as the first display card 51 to facilitate their interchangeability. The second display card 53 has different graphics to provide a different game to the player, as well as the tab opening being located in a different position on the tab to allow a different electrical path to be completed, thereby creating a different game exclusive to the second card. Each display card has a tab opening or tab openings in different positions or of different sizes to create a variety of different electrical paths. Each different electrical path corresponds to a different game that is unique to that particular display card.
A printed circuit board 81 is disposed behind the display card 51. Preferably, the printed circuit board 81 has a plurality of LED's 83 mounted thereon to simulate lights of a stand-up pinball game. Preferably, the LED's 83 are various colors to provide a multi-color display.
A first opening 41 in the housing 21 allows the first display card 51 to be inserted and removed from the housing, as shown in FIGS. 5-10. Preferably, the first opening 41 is in the top face 25 of the housing, as shown in FIGS. 2 and 3. The first opening 41 receives a display card and allows it to be positioned behind the display screen 31 and in front of the printed circuit board 81, as shown in FIG. 11.
A second opening 43 in the housing 21 receives a second display card 53, as shown in FIGS. 8-10. Preferably, the second opening 43 is in a top wall 42 of a pocket 44, as shown in FIG. 6, attached to the back side 24 of the housing 21. The pocket 44 is attached to the housing 21 by a fastener received in the fastener hole 45 in the housing, shown in FIG. 4. The pocket 44 has a back wall 47, bottom wall 48 and side walls 49 and 50 to hold display cards within the pocket. The pocket 44 may store a plurality of display cards 55 to be interchanged with the display card currently received in the first opening 41. A recess 46 in the pocket 44 allows a player to slide out a stored display card with a finger. The fastener hole is positioned within the recess 46.
An impact sensor 61 includes a spring weighted actuator 63 that is attached on one end to the housing 21 and a switch 65 is disposed within the housing 21 of the game 11. The impact sensor switch 65 is activated by movement of the housing 21 when a player nudges or taps the housing. The weighted actuator 63 is attached to the housing 21 at one end 64 and contains a weight 67 on the other end that swings in a pendulum motion when the game is tapped or nudged by the player. The weighted actuator 63 is damped by a torsion spring 69 that maintains a neutral position when the game is at rest. The switch 65 is activated when the weighted actuator 63 moves laterally and contacts the switch when the game is tapped or nudged by the player. Preferably, there are first and second impact sensors 61 and 62. Preferably, the second impact sensor is a mirror image of the first impact sensor, as shown in FIG. 4. A first impact sensor 61 is positioned proximal the left face 27 of the housing 21, and a second impact sensor 62 is positioned proximal the right face 28 of the housing. Movement of the left and right faces of the housing is detected by the corresponding impact sensors 61 and 62, which transmits a signal to the printed circuit board 81, thereby shifting the simulated pinball 71. Preferably, the impact sensor is a conventional reed switch. The program allows a limited number of impacts to change the ball path within a given time frame. If the number of impacts during an established time frame is exceeded, the game will “tilt” and terminate.
A battery compartment 93 receives batteries to supply power for the game 11, as shown in FIG. 4. Any suitable manner of supplying power may be used in lieu of batteries. The battery compartment is preferably accessible from the back face 24 of the housing 21. The pocket 44 is positioned on top of the battery compartment, as shown in FIGS. 5 and 6. The fastener opening in the pocket 44 is positioned within the recess 46. Display cards stored in the pocket 44 cover the fastener in the fastener opening, thereby preventing it from being visible to the player.
Assembly and Disassembly
As shown in FIGS. 1-3, 6 and 10, the hand-held pinball game 11 is shown fully assembled. The hand-held pinball game 11 has first and second openings 41 and 43 for interchangeably receiving first and second display cards 51 and 53 to provide a versatile hand-held electronic pinball game.
The first opening 41 in the top face 25 of the housing receives a first display card 51, as shown in FIG. 1. A second opening 43 in the pocket 44 secured to the back face 24 of the housing receives a second display card 53. Additional display cards 55 may also be housed in the pocket 44. When a player inserts the first display card 51 in the first opening, the first display card is positioned between the display screen 31 and printed circuit board 81, as shown in FIG. 11. Batteries inserted in the battery compartment 93 provide power. Once batteries are inserted in the battery compartment, a fastener is inserted through the fastener holes in the pocket and the back face 24 of the housing 21 to secure the pocket 44 to the housing 21. Display cards received in the pocket 44 cover the fastener to prevent it from being visible to the player.
Pressing the power button 77 causes the batteries to supply power to the printed circuit board 81, display screen 31 and speaker 91. Text messages allowing the player to select various features of the game are displayed in the dot-matrix portion 33 of the display screen. LED's 83 mounted on the printed circuit board are lit to simulate the lights of a stand-up pinball game. Speaker 91 emits sounds in response to play of the hand-held pinball game 11 to simulate the sounds of a stand-up pinball game. Pressing sound button 78 alternately turns the speaker 91 on and off, thereby allowing the player to mute the sounds if desired.
Once the desired features of the game have been selected, a simulated pinball 71 is launched into play by pulling back on the plunger 76. Initially, all the plunger segments 36 are energized. As the plunger 76 is pulled further back, more plunger segments 36 become de-energized and disappear. The fewer plunger segments 36 that are visible, i.e., the more plunger segments that are de-energized, the more power that is to be supplied to the launched simulated pinball 71. If a weaker launch is desired, a minimal amount of plunger segments 36 should be de-energized. The player releases the plunger 76 when a desired amount of plunger segments 36 have been de-energized corresponding to the amount of power to be supplied to the simulated pinball 71.
When the simulated pinball 71 is launched, as shown in FIG. 12, sequential pinball segments 35 are energized, thereby displaying motion of the simulated pinball 71. Flipper buttons 74 and 75 (FIG. 1) are pressed to activate simulated flippers 72 and 73 (FIG. 12) to keep simulated pinball 71 in play. Impact sensors 61 and 62 (FIG. 4) allow the player to alter the path of the simulated pinball 71, as players can do in stand-up pinball games. Impact sensors 61 and 62 sense motion of the left and right faces 27 and 28 of the housing 21 and transmit a signal to the printed circuit board, thereby shifting the path of the simulated pinball. The circuit board may be configured to alter the path of the simulated pinball in any manner desired. Preferably, the path of the simulated pinball 71 is shifted one pinball segment to the left or right according to the face of the housing that is nudged or tapped by the player. The pinball game 11 may also be configured with a counter so that overuse of the nudging or tapping feature results in a tilt and loss of the ball in play, as in a stand-up pinball game. Preferably, the counter is configured to cause a tilt to occur when the nudge feature is used a predetermined amount of times in a predetermined amount of time, such as nudging three times in 90 seconds results in a tilt. The counter resets whenever the predetermined amount of time has lapsed without a tilt occurring.
Whenever the player wants to change the display 13 of the game 11, the first display card 51 is removed through the first opening 41 by gripping the tip 52 of the first display card, as shown in FIG. 6. The first display card 51 may then be inserted in the second opening 43 of the housing to store the first display card for future use. The second display card 53 is slid out of the second opening 43 by pressing a finger in the recess 46 in the pocket 44, as shown in FIG. 6. The second display card 53 may then be inserted in the first opening 41 between the display screen 31 and the printed circuit board 81 to create a new display image in the display 13, thereby creating a new pinball game to be played by the player.
Although described with regard to a hand-held electronic pinball game, the present invention may be used with any suitable hand-held game.
While advantageous embodiments have been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention as defined in the appended claims.
