Abstract
An elongate mast section that when joined to at least one further section along the longitudinal edges thereof forms a mast. Each longitudinal edge has a U-shaped portion including a protruding flange which is joined to the corresponding flange of the adjacent section by means of a joining strip. A wedge is driven between the bases of the flanges to force the flanges into firm frictional engagement with the joining strips to complete the basic mast.
Claims10
An elongate mast section adapted for joining to a second similar mast section to form a yacht mast without use of rivets or weldments, each said mast section comprising:
- an elongate shell having a curved cross-section and opposite ends, each said end having along each longitudinal side an integral inwardly turned web, which joins a flange to said shell;
- each said flange being inwardly turned towards said shell with respect to said web such that the transverse cross-section of the flange, web and the adjacent portion of the side form a substantially U-shaped portion;
- and,
- the outer surface of the base of said U-shaped portion being bevelled such that when said second similar mast section with a complementary bevel is brought into opposing side-by-side relationship with said first section, each of the corresponding bevelled surfaces of said second section forms a substantially V-shaped gap with the corresponding bevelled surfaces of said first section such that the apex of each of said V-shaped gaps is innermost.
