Patent attributes
A pivoting mast device is disclosed for pivoting a mast relative to a surface. The pivoting mast device comprises a mast pivot pivotably coupling the mast to the surface. A lower wheel is rotatably coupled adjacent to a proximal end of the mast. An upper wheel is rotatably coupled adjacent to a distal end of the mast. A linkage couples the lower wheel to the upper wheel. A drive is coupled to the lower wheel for displacing the linkage. An upper traveler slideably engages the mast and is coupled to the headstay. A lower traveler slidably engages the mast and is coupled to the linkage. A lowering stay is secured to the surface and the lowering traveler. A mast lowering displacement is defined by the lower traveler and the upper traveler in a descending direction. A mast raising displacement is defined by the lower traveler in a ascending direction.
