Abstract
Abstract A dart game comprising a stand-up or hanging board having a target supported thereon for rotation about a generally horizontal axis. A plurality of darts are provided and, when thrown, the darts attach to the target. Each attaching dart tends to turn the target about its rotational axis by an amount which is a function of the radial and angular position of the dart on the target, and its relation to other darts attached thereto. Scoring means responsive to angular and/or directional target movement is provided.

Claim 4
Dependent Claim
137 words
A dart game device comprising a base, a movable target supported upon said base, cooperable scoring means on said target and said base and registerable upon movement of said target relative to said base, said scoring means including a progressive scale extending from a minimum to a maximum, and indicator means registering a score on said scale in response to movement of said target relative to said base, dart means including a plurality of darts adapted to successively attach to said target and operable to move said target relative to said base in response to the relative position of the darts on said target and the position of the darts relative to one another, whereby to register a score on said scoring means which is a resultant of the darts secured to said target and acting thereon.
Claim 5
Dependent Claim
149 words
A dart game device comprising a base, a target rotatably supported upon said base for movement about a generally horizontal axis, cooperable scoring means on said target and said base and registerable upon rotation of said target relative to said base, said scoring means including a progressive scale extending from a minimum to a maximum, and indicator means registering a score on said scale in response to rotation of said target relative to said base, dart means including a plurality of darts adapted to successively attach to said target and operable to rotate said target relative to said base in response to the radial and angular position of the darts on said target and the radial and angular position of the darts relative to one another, whereby to register a score on said scoring means which is a resultant of the darts secured to said target and acting thereon.
Claim 6
Dependent Claim
149 words
A dart game device comprising a base, a target rotatably supported upon said base for movement about a generally horizontal axis, cooperable scoring means on said target and said base and registerable upon rotation of said target relative to said base, said scoring means including a progressive scale extending from a minimum to a maximum, and indicator means registering a score on said scale in response to rotation of said target relative to said base, dart means including a plurality of darts adapted to successively attach to said target and operable to rotate said target relative to said base in response to the radial and angular position of the darts on said target and the radial and angular position of the darts relative to one another, whereby to register a score on said scoring means which is a resultant of the darts secured to said target and acting thereon.
Claim 7
Dependent Claim
125 words
A dart game device comprising a board, a target rotatably supported upon said board for movement about an axis, said board being positionable to dispose said target generally vertical and said axis generally horizontal, said target being turnable about said axis in a direction and through an angle which are functions of the angular and radial positions of dart means attached to said target and relative to each other, scoring means including a pair of independent scoring devices each interconnected with said target by one-way clutch means, one of said scoring devices being operable in response to turning movement of said target in one direction, the other of said scoring devices being operable in response to turning movement of said target in the other direction.
