Abstract
Abstract A dart target system comprising a first target movably mounted on a frame for rotation about a first axis, whereby when a greater number of darts are stuck in the target on one side of the axis than the other, then that one side will be below the other side, indicating victory for the player throwing toward the one side. An electrical system forming a part of the dart target system and delivering a light or other sensible signal of one nature when the victory is achieved by a person throwing on one side of the target and of a different nature when a victory is achieved by a person throwing at the opposite side of the target.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A target system comprising a a frame, first target module movably mounted on said frame for rotation about a first substantially horizontal axis, said first target module having a target module surface disposed transversely to said axis, said surface being suitable for penetration by pointed ends of darts sufficient to support and retain darts stuck therein whereby a dart stuck in said first target module on one side of a vertical plane extending through said axis tends to cause said first target module to rotate about said first axis downwardly on the side of said vertical plane in which said dart is stuck, a dart with a pointed end, said pointed end being stuck in said target module surface, a victory indication means correlated with said first target module and said frame, whereby at a given time the position of said first target module with respect to said frame can be sensed by the players, said victory indication means comprising an electrical signal system having a sensible signal. said signal being activated responsive to the position of a magnetically attractable member with respect to a magnetically operated switch, the magnetically attractable member and the magnetically operated switch being permanently mounted during use of said system one on said target module and one on a portion of said system which is fixed to said frame.
Claim 2
Dependent Claim
224 words
A target system comprising a a frame, first target module movably mounted on said frame for rotation about a first substantially horizontal axis, said first target module having a target module surface disposed transversely to said axis, said surface being suitable for penetration by pointed ends of darts sufficient to support and retain darts stuck therein whereby a dart stuck in said first target module on one side of a vertical plane extending through said axis tends to cause said first target module to rotate about said first axis downwardly on the side of said vertical plane in which said dart is stuck, a dart with a pointed end, said pointed end being stuck in said target module surface, a victory indication means correlated with said first target module and said frame, whereby at a given time the position of said first target module with respect to said frame can be sensed by the players, said victory indication means comprising an electrical signal system having a sensible signal. said signal being activated responsive to the position of a magnetically attractable member with respect to a magnetically operated switch, the magnetically attractable member and the magnetically operated switch being permanently mounted during use of said system one on said target module and one on a portion of said system which is fixed to said frame.
Claim 3
Dependent Claim
18 words
The dart target system of claim 1 in which said victory indication means comprises blinking electrical light sources.
Claim 4
Dependent Claim
46 words
The dart target system of claim 1 in which a backing is attached to said frame and surrounds said first target module, said backing being adapted to be penetrated by the pointed end of a dart so as to permit a dart to be stuck therein.
Claim 5
Dependent Claim
30 words
The dart target system of claim 3 in which a second target module is movably mounted alongside said first target module as said system is seen from its forward side.
Claim 6
Dependent Claim
36 words
The dart target system of claim 3 in which a a second target module is movably mounted alongside of said first target module and within said backing as said system is seen from its forward side.
Claim 7
Dependent Claim
32 words
The dart target system of claim 3 having said backing and said first target module each provided with a substantially vertically forward surface, said forward surfaces being in substantially the same plane.
