摘要

#CMT# #/CMT# The device has skittles (7) with a ball (11) and suspended by a rod (8) connected to a ball joint that is positioned on a lever rotating at an end of a rotating arm (5). An electrical detection system emitting a horizontal light beam (13) is cut by a cylindrical case, when the skittles are stroked by the ball. The skittles are provided in a vertical position with respect to a track (2), when the skittles are not stroked by the ball. #CMT#USE : #/CMT# Bowling device. #CMT#ADVANTAGE : #/CMT# The configuration of the device permits a player to alternatively play two different games combining the existing bowling game and reversed bowling game in an independent manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic elevational and sectional view of a bowling device with different positions of skittles. 2 : Track 5 : Rotating arm 7 : Skittles 8 : Rod 11 : Ball 13 : Horizontal light beam.
