Abstract
A pin setting apparatus for a ten pin bowling apparatus comprises a parallelogram linkage assembly which carries a plurality of pin engaging devices and which may be moved between an expanded attitude, wherein the pin engaging devices are arranged at desired locations of pins on the pin deck of the bowling apparatus, and a contracted attitude, wherein pins may be collected from a pin supporting assembly. The linkage assembly is movable between a position overlying the pin deck for depositing or collecting pins and a position spaced from the pin deck for collection of pins from the pin supporting assembly.
Claims22
Pin setting means for use with a ten pin bowling apparatus of the type including a bowling lane and a pin deck at the end of said lane for supporting ten pins thereon, said pin setting means including a linkage assembly comprising a plurality of pivotally interconnected link members, at least some of said link members being interconnected to form a parallelogram linkage structure, pin engaging means supported at spaced apart positions on said linkage assembly, linkage supporting means for supporting said linkage assembly for movement between a first attitude overlying said pin deck and a second attitude wherein said linkage assembly is moved away from said pin deck, said linkage supporting means including substantially horizontal guide means adapted to extend longitudinally of said bowling lane, carriage means mounted for movement along said guide means and supporting one end of said linkage assembly and actuating means connected to the opposite end of said linkage assembly, said actuating means including a plurality of pairs of cross linkage members pivotally interconnected intermediate their ends and to the linkage members of adjacent pairs of linkage members, a plurality of support carriages supported for movement along said guide means and supporting said linkage members, and stop means on said guide means, said actuating means being actuable for moving said linkage assembly between said first and second attitudes, said stop means being engaged by said carriage means when said linkage assembly is moved towards said second attitude and wherein movement of the other end of said linkage assembly by said actuating means subsequent to said carriage means engaging said stop means causing said linkage assembly to move to an expanded position wherein said pin engaging means are disposed at locations corresponding to desired positions of said pins on said pin deck to enable deposit of pins thereon or collection of pins therefrom, said actuating means being further actuable to move said linkage assembly from said first to said second attitude and into a contracted position wherein pins may be collected by said pin engaging means from pin supporting means.
Pin setting means for use with a ten pin bowling apparatus of the type including a bowling lane and a pin deck at the end of said lane for supporting ten pins thereon, said pin setting means including a linkage assembly comprising a first pair of parallel linkage members and a second pair of parallel linkage members, the linkage members of said first pair being pivotally interconnected at their opposite ends to opposite ends of said linkage members of said second pair, and a pair of intermediate linkage members pivotally interconnected intermediate their respective ends and wherein one of said intermediate linkage members is disposed between and extends parallel to the linkage members of said first pair of parallel linkage members and is pivotally interconnected at its opposite ends to the respective linkage members of said second pair of parallel linkage members and wherein the other of said intermediate linkage members is disposed between and extends parallel to the linkage members of said second pair of parallel linkage members and is pivotally interconnected at its opposite ends to respective linkage members of said first pair of parallel linkage members, pin engaging means supported at spaced apart positions on said linkage assembly, means for supporting said linkage assembly for movement between a first attitude overlying said pin deck and a second attitude wherein said linkage assembly does not overly said pin deck, and means for expanding and contracting said linkage assembly so as to move said linkage assembly between an expanded attitude wherein said pin engaging means are disposed at positions corresponding to desired positions of said pins on said pin deck to enable deposit of pins thereon or collection of pins therefrom, and a contracted attitude wherein pins may be collected by said pin engaging means from pin supporting means.
Pin setting means for use with a ten pin bowling apparatus of the type including a bowling lane and a pin deck at the end of said lane for supporting ten pins thereon, said pin setting means including a linkage assembly comprising a plurality of pivotally interconnected link members, at least some of said link members being interconnected to form a parallelogram linkage structure comprising a first pair of parallel link members and a second pair of parallel link members, the link members of said first and second pair being of substantially the same length, the link members of said first pair being pivotally interconnected at their opposite ends to opposite ends of the link members of said second pair, pin engaging means supported at spaced apart positions on said linkage assembly, means for supporting said linkage assembly for movement between a first attitude overlying said pin deck and a second attitude wherein said linkage assembly does not overly said pin deck, and means for expanding and contracting said linkage assembly so as to move said linkage assembly between an expanded attitude wherein said pin engaging means are disposed at positions corresponding to the desired positions of said pins on said pin deck to enable deposit of pins thereon or collection of pins therefrom, and a contracted attitude wherein pins may be collected by said pin engaging means from pin supporting means, opposite pivotal connections between respective link members of said pairs of parallel link members being moved towards and away from each other upon expansion and contraction of said linkage assembly.
