  • FIG. 1 illustrates a mode of play of the invention.
  • a puck 1 slides virtually friction free across the playing surface 2 of the air cushion table.
  • Contestants 3 standing at opposite ends of the table slide their bats 4 across the playing surface and attempt to knock the puck 1 into the opponents goal 5.
  • a light within one of a bank 6 of vertically extending score boxes 7 alongside of the table is automatically illuminated registering the score.
  • FIGS. 2 and 3 illustrate the construction of the air cushion bed 11 of the game table 12.
  • the top 13 or playing surface of the bed is a one-sixteenth inch sheet of a smooth durable material such as Melamine.
  • Air holes 14 having a diameter of 0.032 inches are drilled in a one inch grid pattern covering the playing surface 13 of the table 12.
  • the melamine playing surface rests upon and is securely affixed to a one inch thick core 15 of pressed wood, into and through which air channels 16 and ducts 17 have been cut.
  • Each channel 16 extends over the length of the playing surface 13 of the table and has communicating therewith one row of holes 14, so that each row of holes is supplied by a single channel 16. Air is fed into the channels 16 through slot-like ducts 17 which vent the channels 16 through the lower surface 18 of the core 15.
  • a one-eighth inch sheet of phenolic 20 is mounted to the bottom of the core 15 to strengthen the entire air bed structure. Apertures 21 matching the ducts 17 in the core 15 are cut in the phenolic 20.
  • a plenum chamber 22 is created by mounting a bottom panel 23 of one-half to three-quarter inch plywood or the like one inch below the lower surface 24 of the phenolic panel 20. The plenum chamber 22 is bounded at each side 25 by one inch thick spacing stringers 26 which extend the length of the table 12 and are secured between the bottom plywood panel 23 and the phenolic panel 20 above. The plenum chamber is restricted in length by one inch thick cross braces 27 which extend across the table between the side stringers 26, and are also securely attached between the bottom panel 23 and the phenolic panel 20 above. 7
  • the plenum chamber 22 is supplied with air by a fan 30 mounted to the bottom panel 23 so as to exhaust upwardly through an aperture 31 therein and into the plenum chamber 22.
  • a housing 32 may be placed over the fan 30 for purposes of appearance and noise abate- 'ment.
  • a series of apertures 33 in the fan housing 32 provide a sufficient air supply to the fan intake.
  • a quarter-inch stainless steel bumper strip 10 is mounted flush with the playing surface 2, and extends vertically upwardly therefrom to the height of approximately three-quarter inches.
  • the steep bumper strip 10 may be epoxied or otherwise securely fixed to the wood side rail 41, or the rail and bumper strip may comprise an integral metal component, but it is important that its inner face 42 be smooth and extend substantially perpendicular to the playing surface 2 in order that it not exert any vertical forces upon a striking puck which could cause it to take off.
  • the side and end rails 41 of the table are anchored upon the air bed 11 by a key 43, preferably of steel, which extends equally into the rail 41 and the air bed 11.
  • the wood rails 41 may then be securely fastened to the air bed 11 by bolts 44 which threads into tee nuts 45 embedded in the air bed 11, or alternately by the bolts 44 which may extend through the entire air bed structure.
  • a skirt 46 extending from the outer edge of the wood side and end rails 41 may be utilized as illustrated in FIG. 1 to hide the sub-structure of the air bed and fan assembly.
  • FIGS. 5 and 6 illustrate the preferred embodiment of the bat of the invention.
  • the bat body 49 is a one inch thick disc of high-density thermoplastic such as polyethylene, covered on the bottom 50 with a thin layer of felt 51 to avoid scarring of the playing surface of the air bed.
  • the top 52 of the bat 4 is dished as at 53 primarily for two reasons. First, to lower the center of gravity of the bat by lowering the handle portion, and second, to provide protection for the fingers of the player.
  • a spherical handle 54 such as a billiard ball, is attached to the center of the bat 4 and at the bottom of the dish 53 as by a screw 55 extending up through the bottom of the disc 49 forming the body of the bat 4.
  • the thickness 56 of the bat 4 should be at least twice the thickness 58 of the puck 1 and slightly greater than the height of the goal opening in order to avoid any possibility of the bat 4 sliding under the puck l, permitting it to strike the hand of the contestant, and preventing the bat from being caught in the goal.
  • the heighth of the vertical side face of the bat 4 is one inch
  • the thickness 58 of the puck 1 is approximately one-quarter inch.
  • FIGS. 7 and 8 illustrate the preferred embodiment of the puck, a flat circular disc also made of high-density thermoplastic, e. g. polyethylene. With a diameter of three inches and a thickness of one-quarter inch the weight of the puck will be supported by at least four air jets at all times.
  • high-density thermoplastic e. g. polyethylene
  • the sides of the puck l, bat 4, and bumper strip be as nearly mutually vertical as feasible to avoid imparting to the puck an angle of attach which would cause it to leave the table. Further, in order to provide the contestant with a feeling of solid contact when hitting the puck, and to further avoid any tucking or other reactive movement of the bat upon contact with the puck, it has been found most advantageous to use a bat to puck weight ratio of approximately l0-to-l.
  • FIGS. 9 and 10 illustrate a promising alternate construction to support the perforated playing surface 2 of the air bed 1 1.
  • the one-eighth inch Melamine playing surface 2 would be backed by a supporting layer 60 of pressed wood or the like having quarter-inch holes 64 therein each communicating with one of the smaller holes 14 in the playing surface 2.
  • This supporting layer 60 would in turn rest upon an egg crate-like supporting assembly 61 such as that illustrated in FIG. 9 where the crossing members are notched and interfitted so that the lateral members 62 are elevated above the longitudinal members 63.
  • the supporting layer 60 rests upon the lateral member 62 and the bottom panel-23 is attached to the longitudinal member 63. Air from the plenum 22 is free to circulate over the longitudinal member 62 and under the lateral elements 62 to reach all of the air holes 64-14 of the playing surface 2.
  • FIG. 11 illustrates one form of bat conceived and tested during the development of the invention and is included for purposes of comparison.
  • the body 65 was made of a solid piece of steel. It is apparent that the rectangular shape, additional weight and handle configuration of this bat would result in a significant change in the character and mode of play of the game from that accompanying play with the circular bat 4 of FIG. 5.
  • the goal 70 basically comprises a horizontal slot 71 in the bumper strip 10 and rail 41 of the table having an opening approximately 3 times the diameter of the bat 4 and a housing to retain the puck l. lnitially the puck slides through the slot 71 in the bumper strip 10, and through the end rail 41 of the table. Upon reaching the edge of the playing surface 2, the puck is transitioned from the horizontal to the vertical plane by a curving nylon liner 73, and delivered into a slender vertical chamber 74. The side walls 75 of the vertical chamber 74 are configured to guide the puck as it continues downwardly into an exit channel 76.
  • a solenoid operated blocking pin 85 extends into the exit channel 76 and retains the puck in an inaccessible position within the goal housing.
  • FIG. 14 illustrates one form of illuminated score presentation suitable for use with the invention.
  • a translucent housing 80 is mounted upon the rail 41 along each side of the table. Within each housing 80 are a series of compartments 7 separated by opaque baffles 84.
  • the side windows 86 of each compartment have numbers 81 etched or otherwise placed thereupon such that they will be illuminated when a lamp 82 is lighted by the scoring circuit. As each successive numbered chamber is lighted, the preceding chambers remain illuminated. When all of the chambers on one side of the table are illuminated the game is over; however, the boxes 7 will remain illuminated for a short period of time after the game is over or until the coin mechanism is recycled.
  • FIG. 15 is a schematic diagram of the electrical circuitry and related devices which control play and scoring on the table. A period of fifteen minutes is allowed for the game. The insertion of a specified amount of coin money into a coin operated mechanism starts a 15 minute timer 91 which controls a power supply 92 to the fan 30 and the remainder of the scoring mechanrsm.
  • Line power of 110 volts AC is connected to the fan motor 93 through a fan relay switch 94, and to a trans forrner 95 which supplies 24 VAC to a rectifier 96.
  • Actuation of the fifteen minute timer 91 closes a first switch 97 which will remain closed for the allotted period of fifteen minutes.
  • the switch 97 is connected in series with the low side 98 of the transformer 95 and the rectifier 96, so that its closing supplies power to the rectifier for the 15 minute period. Closing of the switch 97 also causes power to flow through the fan relay switch 94, closing that switch and initially connecting line power 92 to the fan motor 93.
  • Operation of the coin mechanism 90 also momentarily closes a second switch 99.
  • Switch 99 is in series with a 24 VAC reset coil 100 connected across the low side 98 of the transformer 95.
  • the momentary activation of the coil 100 resets a stepping switch 83 to the zero score position.
  • the stepping switch 83 functions to connect 24 VDC power sequentially and cumulatively to the lamps 82 in the score indicating boxes 7.
  • the stepping switch 83 is advanced each time a goal detecting switch 78 positioned within the puck exit channel 26 is actuated by l a puck passing through the goal.
  • Goal detecting switch 78 is spring biased to the open position and is momentarily closed by the displacement of its trip elements 77 by a puck 1 as it passes through the exit channel 76.
  • the switch 78 is connected in series with a relay 101 incorporated within the stepping switch 83, and across the low side 98 of the transformer 95. Each time the relay 101 is activated by the closing of the goal detecting switch 78, the contact arm 102 of the stepping switch 83 is advanced one position.
  • the arm 102 is advanced to a contact 103 completing a 24 volt DC circuit 104 from the rectifier 96 and through a lamp 105 which illuminates the No. 1 goal chamber of the score indicating bank 6.
  • Unidirectional diodes 107 are connected between successive lighting circuits, like circuit 104, so that as the 5 stepping arm 102 advances, power will continue to be supplied to all previously illuminated score indicating lights keeping all lighted until the end of the game.
  • the scoring circuit provision is made for an arbitrary number of seven goals.
  • the stepping arm 102 reaches a contact 108 which in addition to illuminating the bulb 109 for the seventh goal, also connects 24 VDC power to a final score relay 110.
  • Final score relay 110 controls a switch 110A which is in series with a puck gate solenoid 111 connected across the low side of the transformer 98': Contact 110A is closed when switch 97 is closed, supplying power to the puck gate solenoid 111 and holding the spring loaded blocking pin 85 in the withdrawn position.
  • the final score relay 110 disconnects power to the puck gate solenoids 111 permitting the spring loaded blocking pin 85 to extend across the exit channel 76 and trap the game puck in an inaccessible position.
  • Relay 112 controls a switch 112A connected in series with the power supply 92 and the fan 30. Activation of this relay 112 opens the switch 112A, which is biased to the closed position, cutting off power tothe fan 30.
  • a game comprising, in combination: an air bed including a powered fan discharging air upwardly through holes in the surface of the air bed;
  • a bumper strip of high-density, substantially nondeformable material extending substantially around the perimeter of and defining a playing area upon said air bed, the face of the bumper strip being smooth and substantially perpendicular to the surface of the air bed;
  • disc-shaped puck game piece having an area and weight such that it floats upon said air bed and is capable of moving over said playing area generally without touching it;
  • a goal associated with said playing area said goal communicating with said playing area via an opening in'said bumper strip through which said game piece may pass to said goal, said goal including means for detecting the passage of the game piece therethrough and wherein said game further includes means responsive to. said detecting means for automatically indicating to a player that a goal has been scored, said goal including a passage therein through which said game piece passes upon the scoring of a goal and said detecting means including means for sensing the passage of said game piece through said passage; and
  • bat means adapted to slide upon said air bed for slidingly engaging said game piece so as to cause it to move upon said air bed and over said playing area i to said goal, said bat means comprising a disc having a vertical side face and a handle extending upwardly therefrom.
  • said automatic score indicating means comprises a plurality of individually illuminable score indicating compartments, and means responsive to said goal detecting means to illuminate one of said compartments each time a goal is scored.
  • each of said illuminable compartments indicates the total of goals scored by a player
  • said means to illuminate said compartments includes means to light said compartments sequentially upon the scoring of successive goals, and means to maintain all light compartments in the illuminated state for a preselected time period after play has concluded.
  • said goal comprises an enclosure inaccessible to the players through which the game piece must pass when a goal is scored, a channel by which the game piece may exit said enclosure and means associated with said exit channel for retaining the game piece in a position accessible to the players and further including means positioned within said enclosure for blocking the exit of the game piece upon the scoring of a preselected number of goals.
