This invention relates to games. In particular, this invention relates to a game in which a frame supporting a play surface is equipped to move a play object across the play surface.
Many games, such as foosball, air hockey and billiards, involve play on a surface supported by a frame, such as a table. Foosball (or “table football” as it is known in Europe), for example, emulates the game of soccer and involves the turning or spinning of players fixed to rods to strike a ball towards an opponent's goal.
Air hockey involves an air hockey table and players striking a puck with a mallet towards an opponent's goal. Air hockey tables typically have some mechanism that produces a flow of air from the play surface that opposes the force of gravity, for the purpose of reducing friction and increasing play speed.
Billiards is another in this family of games, played on a table with a stick used to strike balls, moving them around the table and eventually into pockets.
In drawings which illustrate by way of example only a preferred embodiment of the invention,
This invention relates to a game which uses triggered directed blasts of gas, such as air, to move a play object across a play surface.
The preferred embodiment of the invention is accomplished by providing a game comprising: a frame supporting a play surface, for supporting a play object; a source of compressed gas capable of providing gas for moving the play object across the play surface; a plurality of jets in communication with the play surface for directing the gas to move the play object across the play surface, the plurality of jets being coupled to the source of compressed gas by a plurality of conduits; one or more triggering devices, each for allowing a player to select one or more jets and selectively trigger the release of gas from the one or more selected jets; and a controller coupled to the triggering devices and a plurality of valves, the plurality of valves being biased towards a closed position which prevents gas flow through the plurality of conduits, whereby the controller selects one or more valves based on the one or more selected jets and causes the one or more selected valves to open in response to the trigger, to allow the gas to move through the one or more selected jets for delivery to the play surface.
A further embodiment of the invention is accomplished by providing a game comprising: a frame supporting a play surface, for supporting a play object; a source of compressed gas capable of providing gas for moving the play object across the play surface; a plurality of jets in communication with the play surface for directing the gas to move the play object across the play surface, the plurality of jets being coupled to the source of compressed gas by a plurality of conduits; and one or more triggering devices for allowing a player to selectively trigger the gas from at least one jet, the triggering devices coupled to the source of compressed gas and to a plurality of conduits coupled to the plurality of jets, whereby the trigger allows the gas to move from the source of compressed gas through a selected conduit originating at the triggering device to one or more jets and through the one or more jets to the play surface, whereby the selected conduit was selected based on the position of the triggering device.
A further aspect of the invention is accomplished by providing a pneumatic joystick comprising: an input for receiving gas; one or more outputs for delivering gas; a ball having a conduit one end of which is coupled to the input and the other end of which is aligned to be in communication with at least one of the outputs through rotation of the ball; a ball-rotating member connected to the ball for rotating the ball; a trigger engaging a blocking member within the ball-rotating member, the blocking member blocking gas from flowing between the input and the outputs when the trigger is not depressed, and the trigger moving the blocking member when the trigger is depressed to allow gas to flow between the input and at least one of the outputs.
The game played in the preferred embodiment of the present invention is a game in which players select jets and trigger blasts of air from selected jets, which are in communication with the play surface, to direct a ball or other play object into a goal or other scoring or point changing location in order to score points. The game typically involves two people, but other embodiments may involve only one person or more than two people. A one-player mode allows for play against a computer-controlled opponent. Two-player mode is one player versus another player. Three or more player mode allows two or more teams to compete against each other where one or more teams have more than one player and the control of jets is divided so that one player controls only a portion of that team's jets.
As shown in
The game table 10 should provide sufficient stability for rough play, and preferably have areas for a logo or nameplate and for score keeping. The game table 10 may also include a play object return 27 for returning the play object after a point or goal is scored. The game table 10 may also accommodate mechanisms for coin- or credit card-operated use 29 as shown in
Referring now to
An enclosing cover 35, which is preferably transparent plastic, may be attached to the table 10 so as to be positioned a sufficient distance above the play surface 20 to allow room for the play object 30 to rise above the play surface 20, and still allow players to view the play surface 20. The enclosing cover 35 may be flat or curved, and close to the play surface 20 or farther away, as desired. The enclosing cover 35 shields the play surface 20 from air currents proximate the play surface 20 which might oppose or affect the bursts of gas from the jets 50, thus providing more reliable movement and speed of the play object 30 during play. The enclosing cover 35 also prevents the play object 30 from leaving the play surface 20 and game table 10 entirely, and protects the play surface 20 and jets 50 from food and drink spills or other damage. Enclosing cover 35 may include an opening for inserting the play object 30 to start or resume play. Alternatively, there may be an opening 28 in the walls of game table 10 for inserting the play object 30 to start or resume play.
The source of compressed gas is capable of providing a flow of gas (for example air) sufficient to move the play object 30 across the play surface 20 of the game table 10. Gas may be supplied by a compressor 40 or an air pump, such as a linear magnetic pump 45, or from a compressed gas canister or any other suitable source of compressed gas, at a pressure sufficient to provide the flow of gas necessary to move the play object 30 across the play surface 20. In a preferred embodiment, the source of compressed gas may be mounted on game table 10, for example to the underside of the table 10.
In a preferred embodiment, the source of compressed gas contains air at a pressure of 30-60 psi (1-2 scfm), which is suitable for use with 0.25″ pneumatic tubing to move a play object 30 that is about the size and weight of a ping-pong ball. Different pressures may be used, varying with the cross-sectional area of the jets 50, the size and weight of the ball, and the shape and friction of the play surface 20 and the desired play object speed.
A plurality ofjets 50 are positioned in communication with, preferably proximate to, the play surface 20, for directing the flow of gas to move the play object 30 across the play surface 20. The plurality of jets 50 is coupled to the source of compressed gas by a plurality of isolated conduits such as pneumatic tubing 60. In a preferred embodiment, a jet 50 has a teardrop-shaped opening, as shown in
Each jet 50 may be stationary or adjustable. If the jet is stationary, it is preferably integral with the game table 10 and its orientation cannot be adjusted. In the embodiment shown in
If the jet 50 is to be adjustable then the jet 50 may alternatively be incorporated within a jet module 55. A jet module 55, shown in
In a preferred embodiment for the game of soccer as illustrated in
A triggering device such as a joystick 70, having one or more triggers 75, is used to allow a player to selectively direct the flow of gas from the source of compressed gas to a particular jet 50 in order to attempt to move the play object 30. The joystick 70 is tilted in a direction associated with the particular jet 50 to be actuated. Preferably jets 50 are associated with joystick coordinates in an intuitive manner, such that moving the joystick forward corresponds to a player's front-line or “forward” jets and moving the joystick left corresponds to a player's left-side jets. When the trigger 75 is depressed, gas, such as air, flows through the jet 50 associated with the direction of the joystick 70 at the moment that the trigger 75 is depressed. The joystick 70 may be electronic or pneumatic and may be composed of one or more of a variety of materials such as plastic, metal and wood. The joystick 70 may include leather, plastic or rubber grips, and may be of various colours and/or shapes.
Preferably, the joystick 70 is an electronic joystick. When the joystick 70 is an electronic joystick, a signal is sent to a controller, such as a microprocessor 80 with an associated input/output processor 82, when the trigger 75 is depressed. The microprocessor 80 receives the input signal indicating the x-axis and y-axis coordinates of the electronic joystick handle. At the moment that the trigger 75 is depressed, software code executes to cause one of a plurality of valves 90, which may be solenoid valves, to open. Since the electronic joystick 70 is coordinate-based, it can be configured for use with any number of jets 50 by loading conventional software code into the microprocessor 80 which is then programmed for use with the appropriate number of jets 50. In a further embodiment, the rotation of jet modules 55 may be driven by a driver, such as a motor, controlled by the microprocessor 80 to allow a player to rotate the jet module 55 before or during play. In this embodiment, the electronic joystick handle may be twisted in the z-axis to rotate the particular jet module 55 selected by the x-axis and y-axis coordinates of the electronic joystick handle.
The plurality of solenoid valves 90 may be placed together on manifolds and each valve 90 is biased to a closed position, blocking the flow of gas from the source of compressed gas. The source of compressed gas supplies gas, such as air, to the solenoid manifolds 95. The pneumatic tubing 60 connects the outlets of the solenoids to the jets 50 in communication with the play surface 20 by feeding gas from the bottom, beneath the play surface 20. This allows the pneumatic tubing 60 to be hidden under the play surface 20. Sample schematics of the connections between the joysticks 70, controller, manifolds 95, valves 90, source of compressed gas and jet modules 55 (seen from the underside of the table 10) according to the preferred embodiment are shown in
Alternatively, the joystick may be a pneumatic joystick 100 as shown in
As shown in
If a compressor 40 is used as the source of compressed gas, there is constant compressed gas available at the input 125. If an air pump, such as a linear magnetic pump 45, is used, an inductive proximity switch 155 embedded in the joystick ball 130 or an electrical switch interlocked with the trigger 75 can send the air pump a signal which would only allow compressed air at the input 125 when the trigger 75 is depressed. Optionally, a timer can be added to the switch to limit the flow of air to a momentary blast when the trigger 75 is depressed. This ‘one-shot’ feature could alternatively be achieved mechanically in the trigger switch mechanism in the joystick handle 150. The trigger switch mechanism can be configured to raise the spring loaded metal rod 110 as the trigger 75 is being depressed, but then drop the rod 110 back down once the trigger 75 is fully depressed. If a timer or other mechanism for enabling a one-shot feature is not used, the pneumatic joystick 100 allows compressed gas to continue to flow through one or more of the output tubes 140 as long as the player is depressing the trigger 75. In either case, in this alternative embodiment, little or no compressed gas flows to the jets 50 until the trigger 75 is depressed.
The triggering device need not be an electronic joystick 70 or pneumatic joystick 100. Alternative triggering devices may include a mouse, a trackball, buttons or a touchpad. Further, in an alternative embodiment the joystick 100 can itself serve as a trigger when moved to an actuating position, the centre position of the joystick 100 being neutral and blocking gas from all output tubes 140.
In a further embodiment, a player may compete against a computer-controlled opponent. In this embodiment, sensors, such as distance measuring sensors 180, are used to provide inputs to the microprocessor to determine the coordinates of the play object 30. The microprocessor code then activates one or more appropriate jets 50 based on the location of the play object 30.
The game table 10 may be fitted with either a manual or electronic score keeping mechanism. A manual score keeping mechanism 160 may include numbers or markers that slide to indicate the current score. An electronic score keeping mechanism may include a digital display 170 for displaying the score or point total and sensors 175 to detect when the play object has entered a score or point changing location. Moreover, a speaker module 185, as shown in
