发明名称 WINDSURFING SPREADER
摘要 <p>An improved windsurfing spreader (10) having at least one pulley (20) mounted thereon to rotatably engage the harness line and mounted in a manner to facilitate disengagement of the harness line from the pulley, when desired. The spreader (10) is very light in weight and is strong enough and rigid enough to withstand the stresses of windsurfing, yet is sufficiently flexible to provide a shock-absorbing function to prevent injury to the surfer.</p>
