Abstract
A string bowling pin as described herein incorporates one or more improvements that extend the time between maintenance and repair events that might otherwise be required at the place where the string leads from the top of the pin. A free-floating bushing improves the longevity of the string and pin connection. In another example, a radiused opening at the top of the pin improves the longevity of the string and pin connection. Also, both the improved bushing and radiused opening at the top of the pin, either alone or together, make the pin less likely to tangle with other strings and pins during use.
