This invention relates generally to games and, more particularly, to a target game played on a lawn in which players toss darts having electrically conductive portions at a target having electrical grids for sensing a position of impact.
The traditional game of lawn darts was enjoyed by families for many years. In this game, darts were tossed at a target that laid flat on the grass and the darts had a pointed tip that would penetrate the ground and thus indicate the position of the dart relative to the target. While this game was entertaining, it was seen by many as being unacceptably dangerous in that the pointed metal tip of each dart—which was capable of penetrating the ground—was a danger to children who may be inadvertently struck by it.
Various electronic target games and, more particularly, dart-related games have been proposed in the art. Although assumably effective for their intended purposes, these target games do not provide a game for play upon a lawn in which darts may be tossed upon a target and a position of impact detected electronically.
Therefore, it would be desirable to have a target game in which darts having electrically conductive portions may be tossed at a target having electrical grids for sensing a position of impact. Further, it would be desirable to have a target game in which determines and records the position of a dart tossed upon a target by sensing changes in electrical capacitance within concentric electrical grids. In addition, it would be desirable to have a target game that is safe for children and adult players.
A target game according to the present invention includes a target area having a first electrical grid and a second electrical grid, the first grid being separate from and out of contact with said second grid. The first and second grids are configured to maintain a predetermined spacing therebetween. The target game also includes a processor in communication with a power supply and the first and second grids so as to actuate the power supply to impart a level of capacitance between the first and second grids, to measure an amount of time required for the level of capacitance between the first and second grids to be discharged, and to detect a change in the amount of time required for the level of capacitance between the first and second grids to be discharged.
The game further includes at least one dart having a conductive front portion sized to span the predetermined spacing between the first and second grids. An output device is in data communication with the processor for conveying the detection of a change in an amount of time required for the level of capacitance between the first and second grids to be discharged. It is understood that the target area may include more than one target area, such as an outer area, an inner area, and perhaps even another inner area. Each target area may function as described previously although each may be associated with different point values, sounds, etc.
Therefore, a general object of this invention is to provide a target game, for tossing darts at a target area spread out upon a lawn.
Another object of this invention is to provide a target game, as aforesaid, in which the target area is capable of sensing a location of an impact by a dart.
Still another object of this invention is to provide a target game, as aforesaid, that includes darts that do not penetrate the ground and are safe even if they contact a person.
Yet another object of this invention is to provide a target game, as aforesaid, that determines a dart's general position of impact on the target by measuring an amount of time required for a level of capacitance between the first and second grids to be discharged.
A further object of this invention is to provide a target game, as aforesaid, that provides a plurality of light or sound effects corresponding to respective positions of impact by darts upon the target area.
Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

b is an illustration of the processor measuring the time for a level of capacitance to be discharged for detecting a change in capacitance;
A target game 100 according to the present invention will now be described in detail with reference to
The target 110 has at least one target area 112. The embodiments shown in
The target may further include or be otherwise associated with a processor 120, a power supply 125 (e.g., a battery, AC power, etc.), and/or an output device 128. The processor 120 may be in data communication with the power supply 125, the grids 113a, 113b, and/or the output device 128 (
Each dart 150 has a conductive front portion 152 sized to span the predetermined spacing between the respective first and second grids 113a, 113b. In other words, the front portion 152 is large enough to contact a first grid 113a and also a second grid 113b every time it enters a respective target area 112. The front portion 152 may have a blunt (e.g., rounded or flattened) configuration for safety concerns. To provide conductivity, the front portion 152 may be constructed of metal and/or other appropriate materials, such as carbon impregnated silicon based rubber. Each dart 150 may further include stabilizing members 154 as shown in
As shown in
In use, as shown in
The remote control processor 171 may cause the remote control transmitter 172 to transmit data input through the remote control user input device 178 to the target receiver 164, which may then be used by the processor 120 to perform various functions (e.g., functions related to scoring or the output device 128). The processor 120 may cause the target transmitter 162 to transmit data (e.g., score data) to the remote control receiver 174, which may then be used by the remote control processor 171 to perform various functions (e.g., functions related to scoring or the remote control display 176.
It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
