Abstract

Abstract The dart board game includes a dart, a target board having a target face, and cooperating elements for retaining, on the target face, a removably mounted marker on the dart. Such cooperating elements can consist of cooperating "Velcro" strip material. The dart includes a resilient and flexible portion at which the dart body is removably engaged with the marker, so that upon impact of the dart against the target board, the resilient portion of the dart flexes to allow the Velcro strip to engage without disengagement due to bouncing. This flexing motion compresses the resilient portion, which, as it expands, propels the dart body away from the target board to disengage the dart from the marker. In playing one embodiment of the game, in order for the "score" of a marker to count, the player throwing the dart must catch the rebounding dart body after an impact on the target board.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 169 words
A dart board game comprising, in combination, a target board having a target face and a dart including a flexible and resilient tip and a marker removably engaged with said tip, said marker and target board including cooperating means for retaining the marker on the target face upon impact of the dart tip with the target face, said flexible and resilient tip being compressed upon such an impact to propel the dart away from the target face; said resilient tip and marker including cooperating means for normally holding the marker in the tip and for releasing the marker in response to propulsion of the dart away from the target face after an impact whereby the marker is disengaged from said tip and remains on the target face while the dart moves away from the target face; said cooperating means on said marker and resilient tip comprising a centrally located outwardly directed stem on said resilient tip and receptacle means on said marker for frictionally and releasably engaging said stem.
Claim 2
Dependent Claim 169 words
A dart board game comprising, in combination, a target board having a target face and a dart including a flexible and resilient tip and a marker removably engaged with said tip, said marker and target board including cooperating means for retaining the marker on the target face upon impact of the dart tip with the target face, said flexible and resilient tip being compressed upon such an impact to propel the dart away from the target face; said resilient tip and marker including cooperating means for normally holding the marker in the tip and for releasing the marker in response to propulsion of the dart away from the target face after an impact whereby the marker is disengaged from said tip and remains on the target face while the dart moves away from the target face; said cooperating means on said marker and resilient tip comprising a centrally located outwardly directed stem on said resilient tip and receptacle means on said marker for frictionally and releasably engaging said stem.
Claim 3
Dependent Claim 25 words
The dart board game as defined in claim 1 wherein said resilient tip comprises an elastic hollow shell mounted on one end of the dart.
Claim 4
Dependent Claim 17 words
The dart board game as defined in claim 2 wherein said shell is generally semi-spherical in shape.
Claim 5
Dependent Claim 19 words
The dart board game as defined in claim 2 wherein said dart is in the form of a shuttlecock.
Claim 6
Dependent Claim 70 words
The dart board game as defined in claim 2 wherein said cooperating means on said marker and target board comprises a textile covering said marker and target face having outwardly extending hooks formed thereon and a covering on the other side of said marker and target face having outwardly extending relatively stiff hooks thereon adapted to be retained in said loops upon impact of the marker with the target face.
Claim 7
Dependent Claim 28 words
The dart board game as defined in claim 2 wherein said cooperating means comprises a magnetized surface on said marker and a metal surface on said target board.
Claim 8
Dependent Claim 316 words
A dart board game comprising, in combination, a target board having a target face including a plurality of upstanding loop-like elements, and a dart including a resilient impact tip, a marker, and cooperating means on said tip and marker for releasably engaging the marker with said tip, said marker having an impact face including a multiplicity of stiff hook-like elements thereon which are adapted to be retained in said loop-like elements upon impact with the target face, whereby said resilient tip is initially compressed upon impact of the dart tip marker with the target face, absorbing the momentum of the dart at impact, to allow the hook-like elements to engage and become interlocked with said loop-like elements and retain the marker on the target face, thereby to provide an indication of the area of the target struck by the dart, while the return of the resilient tip after impact from its compressed and deformed condition to its normal condition propels the dart away from the target face and the engaged marker; said cooperating means on said tip and marker releasing the engagement therebetween in response to propulsion of said dart away from the target face whereby the marker is disengaged from said tip and remains on the target face while the dart is propelled away from the target face; said cooperating means including a centrally located outwardly directed stem formed on said impact tip and receptacle means on said marker for frictionally and releasably engaging said stem, said stem and receptacle means being respectively dimensioned such that the frictional adhesion therebetween is less than the adhesion between the marker and target face after an impact, whereby flexing of said tip after compression on impact with the target face propels the dart away from the marker and target face and causes said stem and receptacle means to disengage while the marker remains fixed on the target face.
Claim 9
Dependent Claim 316 words
A dart board game comprising, in combination, a target board having a target face including a plurality of upstanding loop-like elements, and a dart including a resilient impact tip, a marker, and cooperating means on said tip and marker for releasably engaging the marker with said tip, said marker having an impact face including a multiplicity of stiff hook-like elements thereon which are adapted to be retained in said loop-like elements upon impact with the target face, whereby said resilient tip is initially compressed upon impact of the dart tip marker with the target face, absorbing the momentum of the dart at impact, to allow the hook-like elements to engage and become interlocked with said loop-like elements and retain the marker on the target face, thereby to provide an indication of the area of the target struck by the dart, while the return of the resilient tip after impact from its compressed and deformed condition to its normal condition propels the dart away from the target face and the engaged marker; said cooperating means on said tip and marker releasing the engagement therebetween in response to propulsion of said dart away from the target face whereby the marker is disengaged from said tip and remains on the target face while the dart is propelled away from the target face; said cooperating means including a centrally located outwardly directed stem formed on said impact tip and receptacle means on said marker for frictionally and releasably engaging said stem, said stem and receptacle means being respectively dimensioned such that the frictional adhesion therebetween is less than the adhesion between the marker and target face after an impact, whereby flexing of said tip after compression on impact with the target face propels the dart away from the marker and target face and causes said stem and receptacle means to disengage while the marker remains fixed on the target face.
Claim 10
Dependent Claim 25 words
