发明名称 Interlocking pool bridge system
摘要 An interlocking billiard cue bridge head adapted to be fixedly mounted to a standard billiard cue bridge stick and including an interlocking capacity provided by a tab assembly integral to the bridge head which can conveniently interlock with the head of another similarly configured pool bridge to thereby effectively create a bridge capable of supporting a cue stick at selectively variable heights which can be greater than the height at which either bridge head is capable individually.
