ABSTRACT:
Wishbone boom mounting for sailboards with a wishbone head section of a synthetic resin, integrally molded onto a curved pipe section of aluminum or synthetic resin for attaching the two spars of a wishbone boom, and a jacket section accommodating the curved pipe section. A collar is connected to the jacket section by at least one web and is placeable on the mast. A locking element is articulated to this collar and receives the mast. A quick-action closure closes and opens the locking element in order to mount the head section to the mast or to detach the head section from the mast. A hinged cover (10) is molded onto the collar (6) of the wishbone head section (1) by a thin flexible hinge (11) and is curved to match the mast (5). A clamping lever (12) is articulated to the collar (6) for tightening and releasing a rope piece (13) forming a loop (14), one end of this rope piece being attached to the clamping lever (12) and the other end to the collar (6) in the region of the thin flexible hinge (11). The loop (14) of this rope piece is tensionable for attaching the wishbone head section (1) to the mast (5) by the clamping lever (12) by an extension (20) on the collar (6) opposite the closing rim (19) of the hinged cover (10) and by guides (22, 23) on the outside of the hinged cover (10).
