发明名称 Lacrosse stick with telescoping handle
摘要 The present invention is drawn to a lacrosse stick with a main shaft and a secondary shaft that telescopes in and out of the main shaft. The telescopic shaft gives the ability to play offense and defense with one lacrosse stick. A twist of a collar attached to the main shaft attaches to the lacrosse head allows the lacrosse stick and head to increase from a minimum length for offensive play to a maximum length for defensive play. A counter twist of the collar will lock the shaft into the desired position length for play.
