Title:
TOOL FOR RECORDING NUMBER OF HITS IN BALL GAME
Document Type and Number:
WIPO Patent Application WO/2017/098761
Kind Code:
A1
Abstract:
A tool for recording the number of hits in a ball game according to the present invention comprises a plurality of beads 20 with holes, and a cord 30 which penetrates through holes 20H in the beads 20 and holds the beads 20 with freedom to slide. The cord 30 is formed from a cord material that does not extend and retract in the axial direction, but which extends and retracts in the radial direction and is normally urged outward in the radial direction. The cord 30 contracts diametrically in such a way as to resiliently latch the walls of the holes 20H of the beads 20, thereby holding the beads 20 in position. In this way, the beads do not become displaced even if a player swings the tool greatly, and thus the number of hits in the ball game can be recorded and verified reliably, in addition to which assembly of the tool is simple.
