Abstract
A trimming gear on the mast top of a windsurfing rig having an adjusting element that can be connected to the sail top and fixed relative to the mast is arranged on the mast top. The adjusting element is actuated by a reducing gear and can be displaced in the longitudinal direction of the mast. Since the adjusting element is actuated by a reducing gear, it is possible to precisely adjust or trim the sail top with a relatively low expenditure of force, namely also in the tensioned state.
Claims21
Trimming device adapted for attachment to a mast of a windsurfing rig having a windsurfing sail, the trimming device comprising:
- an adjusting element which can be displaced in order to adjust a bolt rope tension of the windsurfing sail,
- the adjusting element including a tensioner adapted for displacement in alignment with a longitudinal axis of the mast,
- locking elements for fixing the tensioner relative to the mast,
- a reducing element for increasing force applied to the trimming device, the reducing element acting upon the tensioner along said longitudinal axis, and
- a connector for connecting the tensioner to the sail,
- the trimming device being attached to the mast top of the windsurfing rig.
A trimming device adapted for attachment to a mast of a windsurfing rig having a windsurfing sail, the trimming device comprising:
- an adjusting element having a length which can be varied in order to adjust a bolt rope tension of the windsurfing sail,
- the adjusting element including a tensioner adapted for displacement along a longitudinal axis of the mast,
- locking elements for fixing the tensioner relative to the mast,
- a reducing element for increasing force applied to the mast, which element acts upon the tensioner along said longitudinal axis, and
- a connector for connecting the tensioner to the sail,
- the trimming device being attached to the mast top of the windsurfing rig,
- the tensioner having a threaded section engaging the mast for displacement of the tensioner relative to the mast.
