FIELD OF THE INVENTION
The present invention relates generally to the field of sail systems for wind propelled motion, and more particularly to methods and systems for outrigger sails for mounting on land-based vehicles, including two-wheeled vehicles, such as bicycles.
BACKGROUND OF THE INVENTION
There has been a long-standing interest in attaching sails to land based wheeled vehicles, including bicycles.
However, such devices and systems have tended to be large and bulky, with designs that mimic the operation of a sail on a sail boat. As a consequence, such systems are expensive and impractical, and would be unsafe in ordinary use.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for sails for mounting on vehicles, including two-wheeled vehicles.
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of sail systems for mounting on vehicles
In an aspect, an outrigger sail vehicle system can include:
- a) a vehicle, which can be a two-wheeled vehicle, such as bicycle; and
- b) an outrigger sail device, including:
- i. a mounting base, which can be connected to the vehicle;
- ii. an outrigger arm, such that the outrigger arm can be rotatably connected to the mounting base, such that the outrigger arm can be rotated in a vertical plane from a right to a left side of the mounting base; and
- iii. a boom handle, which is rotatably connected to an outer end of the outrigger arm, such that the boom handle can be rotated in a horizontal plane from an inward inclination angle to an outward inclination angle relative to an elongated direction of the mounting base;
- iv. a sail assembly, which can be connected to the boom handle, the sail assembly including:
- i. a sail frame, which can include a first frame member and a second frame member;
- ii. a sail member, which can be connected to and spanned out by the sail frame;
- whereby, when the mounting base is connected to the vehicle, the sail assembly is rotatable from a right side of the vehicle to a left side of the vehicle.
In a related embodiment, the sail member can further include:
- a) a sail surface; and
- b) a plurality of curved sail spars, which can be connected to an inner side of the sail surface, along a horizontal direction of the sail surface, such that the curved sail spars curve outward, such that an inner side of the sail cloth forms a concave shape in the horizontal direction.
