  • Patent number: 6743116
    Abstract: A golf club includes first and a second shaft members that are releasably connected by a connector that is preferably substantially hollow. The connector has a male connector that has a first portion and a second portion. The second portion is threaded on an exterior surface. The first portion of the male connector is coupled to one of the connecting ends of the shaft members. The connector also has a substantially hollow female connector that is coupled to the other shaft member. The threads on the exterior of the male connector are releaseably mated with interior threads on the female connector to provide an assembled golf club that may be disassembled for travel, but has characteristics that do not substantially vary from a similar conventional club. The mass of one connector is concentrated on its periphery.
