Abstract
This tool for recording the number of swings in a ball game includes a plurality of holed beads 20 and a cord 30 that is passed through the holes 20H of the beads 20 and that holds the beads 20 so that the beads 20 can slide, the cord 30 is formed from a cord material that does not stretch in an axial direction but that stretches in a diametrical direction and that is normally urged in a diameter-expanding direction, and the cord 30 constrict in diameter so as to elastically interlock with the walls of the holes 20H of the beads 20 and hold the beads 20 in position, whereby the beads do not shift even if a player strongly shakes the tool, the number of swings in the ball game can be reliably recorded and confirmed, and the tool is easily assembled.
Claims9
A tool for recording the number of swings in a ball game comprising a plurality of holed beads and a cord that is passed through the holes of the beads and that holds the beads so that the beads can slide, the tool for recording the number of swings in a ball game characterized in that the cord is formed from a cord material that does not stretch in an axial direction and that the cord material comprises a long band-shaped strip urged to return to a band shape even if bent, wherein the cord material is bent into U or C-shaped portions passed through the holes of the beads so that a whole outer face of the cord material elastically interlocks with walls of the holes of the beads by an urging force that causes the long strip to return to the band shape to thereby hold the beads in position and the cord material expands so as to return to the band shape to thereby form band shape portions at portions of the cord material that do not have the beads disposed thereon, whereby the band shape portions comprise a width that is wider than diameters of the respective holes to prevent the beads from shifting along the cord material.
