Description
SUMMARY OF THE INVENTION
The present invention is directed to a novel dart game which adds
the dimension of target movement by dart placement to the scoring.
The game includes a target supported upon a base and turnable by
the force or weight of one or more darts attached thereto. Scoring
is achieved by the degree and/or direction of movement of the
target by the attaching darts. Thus, each player must consider the
force his dart will produce and the relation of that force to the
force of other darts, if any, on the board in selecting a target
area in which to place his dart. In one version, each player
attains a total score by target movement achieved through placement
of his darts alone; in another version, players may attempt to
counteract one another's scoring by resultant target movement when
all darts are attached thereto; in still another version,
sequential placement of all player's darts on the target until all
are so placed causes progressive target movement, with different
directional movement accounting for scoring of different
players.
It will be understood that other methods of scoring are
contemplated, and that as used herein, the term "dart" is
understood to mean any of a variety of missile or projectile type
objects thrown or propelled toward a target and having means for
attachment thereto.
Main objects of the present invention, therefore, are to provide a
novel dart game which includes a target movable in response to
resultant forces thereon caused by the position of darts attached
thereto and/or relative to other attached darts, and wherein
scoring is achieved by the degree and/or direction of target
movement.
Further important objects of the present invention are to provide a
novel dart game of the above character which can employ a variety
of different types of scoring, and which can be played in different
ways, such as, individually with individual scoring, player against
player with counteracting scoring determined by resultant target
movement through the forces of all players' darts attached to the
target, and player against player with individual scoring
determined by target directional movement caused by resultant
forces of all players' darts on the target.
Additional important objects of the present invention are to
provide a novel dart game of the above character which is
relatively inexpensive to manufacture, rugged in construction, and
reliable in use.
Other objects and advantages of this invention will become more
apparent from a consideration of the detailed description to follow
taken in conjunction with the drawings annexed hereto.

DETAILED DESCRIPTION
Referring now more specifically to the drawings, a dart game device
embodying the present invention is illustrated generally at 11 in
FIGS. 1-3 and is seen to include a base 13 shown as a generally
rectangular board. A target 15 illustrated as a generally circular,
flat disc, is rotatably supported upon the base by spindle means 17
for free rotation about a central axis of the target 15.
Dart means including one or more darts 19 is provided and is
adapted to be propelled toward and attach to the target 15. As
shown in FIG. 4, each dart 19 may include an elongated body having
a relatively blunt weighted forward end 21 and a stabilizing
rearward end 23. The forward end 21 is provided with a tip covering
of bur-like, hooked projections 25 set into a base fabric 27.
Molded plastic material of this general type is available under the
Trademark "Velcro" owned by Velcro Corporation, New York.
The illustrated target 15 includes a core 29 covered with a
fabric-like material 31. For example, the material 31 may be a
woven looped fabric, a flockulated carpet material, or any other
suitable material which presents a suitably retentative face for
the bur-like hooks 25 covering the end of the dart 19. The darts 19
are easily removed from the target 15 when desired by pulling, the
hooks 25 and the fabric material 31 having enough "give" to allow
easy intentional release of the dart 19 from the target 15.
In use, the board 13 is positioned substantially vertically as by
hanging on a wall 32, so that the spindle means 17 is disposed
substantially horizontal. The darts 19 are propelled, as by
throwing, toward the target 15. The weighted dart end 21 causes the
bur-like hooks 25 to strike the target surface 31 and, if properly
thrown, the dart 19 attaches to the target 15. The dart 19 has
weight and causes the target 15 to turn about the axis of the
spindle 17 by an amount and in a direction which is a function of
the angular and radial position of the dart 19 on the target 15. If
other darts 19 are already attached to the target 15, the target
will move, with placement of each additional dart 19 thereon, by an
amount determined by the resultant forces of all darts 19 acting
thereon. In the illustrated embodiment, this resultant is the
vector sum of the weighted darts 19 acting about the axis 17 of the
target 15.
Various types of scoring means may be provided. One of the
simplest, and most intriguing, is shown in FIGS. 1 and 4 and
includes an angular indicia segment 33 printed on the board 13. The
target 15 is provided with indicator means, for example, arrows 35
adapted to register with progressively numbered indicia on the
angular segment 33. In the illustrated version, the arrows 35 are
spaced apart a distance and the segment 33 extends through an angle
so that one arrow 35 will register with some area of the segment 33
for any angular position of the target 15.
It will be appreciated that the player is required to accurately
position his darts 19 on the target, especially when two or more
darts 19 are used, in order for the registered "score" to be a
maximum. Thus, it is necessary for the player to take into account
resultant vector gravity forces acting upon all the positioned
darts 19 attached to the target, and the effect of any additional
darts 19 he may throw, in determining where best to position these
darts 19. This is somewhat more of a challange and requires more
skill than many conventional dart games.
Furthermore, it will be appreciated that the dart game device of
this invention mey be used in another manner, that is, with an
opposing player or players trying to counteract the score of his or
their opponents by proper dart placement on the target. Thus, one
player may try to register a maximum score by his placement of
darts, while an opposing player attempts, by his dart placement, to
reduce or minimize that score.
A modified form of dart game and scoring device embodying the
present invention is illustrated generally at 51 in FIGS. 5 and 6
and is seen to include a hollow base or board 53 having a circular
target disc 55 rotatably supported thereon by a spindle 57. The
target disc 55 is covered with a fabric-like material 59 and is
adapted to have one or more hooked tip darts 61 attached thereto.
Thus, the target 55 turns about the axis of the spindle 57 through
an angle and in a direction which is a function of the placement
position of darts 61 thereon and the relation of these darts 61
relative to one another if more than one dart is attached.
The scoring device employed in the embodiment of FIGS. 5-8 utilizes
a pair of scoring wheels 63, 65, respectively connected to a shaft
67 by oppositely acting ratchet clutches. One such clutch is
illustrated at 69 in FIG. 9 as connecting shaft 67 and wheel 63 and
includes a pawl 68 pivoted by a pin 70 within the wheel 63 and
normally biased by a leaf spring 74 into engagement with ratchet
teeth 72 on a hub 76 rigid with the shaft 67. Thus, when the shaft
67 and hub 76 turn in a counterclockwise direction, as seen in FIG.
9, the wheel 63 turns therewith. Clockwise movement of the shaft 67
is accompanied by no movement of the wheel 63 since the teeth 72
can ratchet past the pawl 68.
Scoring wheel is connected to shaft 67 by an oppositely disposed
ratchet clutch (not shown) so that wheel 65 turns with shaft 67
when the latter turns in a clockwise direction, as seen in FIG. 9,
and does not turn when shaft 67 turns counterclockwise. Progressive
indicia 70, 72 are printed in opposite fashion on wheels 63, 65 as
shown, to register progressive scoring on these wheels as they turn
with rotation of the shaft 67.
The spindle 57 has a pulley 71 fixed thereon and interconnected by
an endless belt 73 to a pulley 75 fixed to the shaft 67. Thus, when
the target 55 turns in a clockwise direction, the scoring wheel 63
turns therewith through its ratchet 69 to register a score by means
of indicia 70, while the scoring wheel 65 remains stationary.
Conversely, when the target 55 turns counterclockwise, scoring
wheel 65 turns to register a score by means of indicia 72, while
scoring wheel 63 remains stationary.
It will be appreciated that the scoring mechanism described here
can be utilized in several ways. In one way, opposing players can
attempt to turn the target 55 in opposite directions to register
independent scores on wheels 63, 65, with all darts 61 of both
players ultimately being attached to the target 55. In another way,
one player may first throw all his darts 61 to register his score
on one wheel 63, remove his darts 61, and the other player then
throw his darts to register his score on the other wheel 65. In
still another way, each player may throw all his darts 61 to
register a total score on both wheels 63, 65, remove his darts 61
and set the scoring wheels 63, 65 back to zero, and the other
player likewise throws all his darts to register total score on
both wheels. Still other playing and/or scoring methods are, of
course, possible.
By the foregoing, there has been disclosed a novel dart game
embodying the present invention. However, it will be understood
that various additions, substitutions, modifications, and omissions
may be made to illustrated embodiments without departing from the
spirit of the invention.
