Title:
FRONT BOOM FITTING FOR SAIL BOARD
Document Type and Number:
Japanese Patent JPS62295792
Kind Code:
A
Abstract:
A front boom end for the attachment of a boom to the mast of a sailboard comprises a pair of limbs (15, 16) which diverge rearwardly, each of the limbs having a tubular end to receive the front end of a boom member of a sailboard boom. A curved flange (18) connects the limbs and has a rearwardly facing mast-engaging surface. The curved flange (18) adjacent one of the limbs comprises a web which defines a hook (20). A handle (12) has a bifurcate end the limbs of which straddle the boom end and are connected to the boom end by means of a pivot pin (22), and a loop of rope (13) which is positionable through a hole in the handle, when looped over the hook (20), may be tensioned around the sailboard mast by the handle. The handle (12) can be semi-circular in cross-section so that it overlies a limb (16) of the boom end when closed, but can be made so short that the physical force applicable thereto by a user is insufficient to crush a mast.
