ABSTRACT:
A forked thill head attachment for installing a forked thill to a sail mast of a rigging comprises a forked thill head (1) which, in a top view, is constructed essentially V-shaped, and opposed clamping jaws for gripping about the mast having a rearward vertical gap (17). In order to produce a firm connection between a forked thill and a mast for a rigging, that can be firmly locked and released with little expenditure of force, the clamping jaws (13) are constructed as a separate component from the forked thill head (1) and held by a longitudinal bolt (21) guided through the forked thill head (1) in the longitudinal direction in the plane of longitudinal symmetry. Locking rotation of the screw member provided at the forward outer side of the forked thill head (1) over the longitudinal bolt (21), moves clamping jaws (13) in the longitudinal direction while contacting, in the forward direction, contacting surfaces (11) likewise running, in a top view, V-shaped to one another. A still further simplified manipulation can be achieved (FIG. 5) by an additional quick-locking lever (51).
