Shifting guides for gutter ball prevention on a bowling alley

Abstract

Bowling game apparatus allowing children to get strikes and spares for a high score. Two guides () are provided longitudinally along lane (); two first retainers () are arranged outside the end of lane () near approach () for retaining first ends of the guides (); two second retainers () for retaining the second ends of the guides () are provided over lane () between first retainers () and pins (), and allow, as driven by a second-retainer drive unit, the guide second-end retaining portions of the second retainers () to shift between a guide position and a retract position apart from the guide position. The guides () diagonally intersect the longitudinal direction of the lane (), where they come into contact with the height-wise center of a ball rolling down the lane () ball when the second-end retaining portions of the second retainers () are in the guide position.
