  • Sailboat mast assembly
    Patent number: 4909170
    Abstract: A sailboat mast constructed of two extruded mast sections joined together by two joining sections. The joining sections have either wedge-shaped surfaces or wedge-shaped openings along their edges which mate with wedge-shaped openings or wedge-shaped surfaces at the edges of the mast sections. The mast sections and the joining sections are held together by a thin layer of glue located on the mating, wedge-shaped surfaces. Because of the wedge shapes, when the glue is applied and the mast sections and the joining sections are pressed together, the glue squeezes into a thin, uniform layer which provides a strong joint.
    Type: Grant
    Filed: February 7, 1989
    Date of Patent: March 20, 1990
    Assignee: Sea Tek Incorporated.
