Systems, including apparatus and methods, for controlling a power kite. The systems may include a variable-line kite controller with a rotatable spool bar carrying plural spools, or a fixed-line controller. The systems also may include deployment mechanisms, sheeting mechanisms, cleating mechanisms for the sheeting mechanisms, safety releases, line protectors, and kite boards, among others, for use with variable- and / or fixed-line controllers.

A control device for use with an aerodynamic wing including a bar having a fixed trim adjustment located between the bar and the user. The invention also includes a stopper that permits the user to quickly adjust the range of available dynamic trim. Preferably, the stopper does not lock until it engages the control bar, allowing the user to slide it quickly and easily to the desired location. The control systems of the invention provide a safety depower function when the end of the fixed trim is secured to a safety line.

An apparatus for controlling movement of a flying device, such as a kite. In controlling such movement, the apparatus comprises a series of force transmitting members associated with a control bar to be grasped by an operator. Such association minimizes interference of the force transmitting members with the control bar surface so as to heighten the level of control that the operator may exert over the kite. Such association also permits the operator to achieve, through movement of the control bar, selective adjustments in both the velocity and acceleration at which the kite and the operator are able to move in a single direction.

A control and safety device of a kite wing comprises a stiffening member 11 arranged at each tip of the wing 1 between sliding means 9A, 9B to allow a sliding pre-line 8A to pass through and to maintain a predetermined distance between the front and rear attachments 5A, 5B regardless of the tension applied to the ends of said pre-line.

A lightweight stretch resistant laminated material has a layer of thin flexible film laminated to a layer of stretch resistant reinforcing material. A kite or wing, which is known in the art to comprises a plurality of assembled panels, can have at least one such panel made from the lightweight stretch resistant laminated material.

A control apparatus for a kite powered conveyance device. Port and starboard kite leads (28,32) and / or port and starboard kite control lines (30, 36) connect ends of a control bar (26, 26′) to port and starboard ends of a kite (12). A tether guide (34, 34′, 34″) is connected to one end of the control bar (26) or to one of the kite leads (28, 32). A harness (12) with a spreader bar (18) is adapted to be worn by a user of the kite powered conveyance device. An arm (20, 20′) is connected to the spreader bar (18). A tether connector (42, 42′) and a hook (22, 22′) are rotatably mounted on the arm (20, 20′) for rotation about the longitudinal axis of the arm (20, 20′). The hook (22, 22′) is hooked to the control bar (26, 26′) to connect the control bar (26, 26′) to the spreader bar (18). A tether (38) passes through the tether guide (34, 34′, 34″) and has its first end connected to the tether connector (42, 42′) and its second end connected to one of the Kite control lines (30, 36).

An aerodynamic wing formed by a flexible canopy with an internally routed canopy line for controlling the canopy profile. Preferably, the canopy line is routed through a gatherable tube secured to the trailing edge of the canopy. Tensioning the canopy line alters the canopy profile to facilitate launching the kite.

What is disclosed is a tube kite comprising two front lines which are combined into a tug line and adapted to be releasably secured to the surfer, and comprising two back lines which are adapted to be secured to a bar, wherein a supplementary line serving as an additional front line during the flight phase is provided.

A kite control system including an aerodynamic wing with a leading edge and first and second opposing wingtips, a control device, a first steering line secured to the first wingtip and the control device, a second steering line secured to the second wingtip and the control device, and a trim line secured to the leading edge substantially between the opposing wingtips, wherein the trim line has a user adjustable length device that allows the user to adjust and mechanically fix the length of the trim line while the aerodynamic wing is in flight.

A device is provided for the management of multiple lines attached to a bar, of the type used in power kites for kiteboarding. The device is formed of an elongate body having a shaft region, a spool region adjacent the shaft region and distal thereto, and a line retaining region distal to the spool region. The shaft region has a hollow body having a longitudinal groove running from a proximal opening to a distal end point, and a bar retaining means for retaining a bar against rotational or axial movement. The spool region has a spool shaft defined by proximal and distal containment means for retaining spooled lines wound about the spool shaft. A line retaining region has a means for separately retaining one or more lines of a plurality of lines.

A kite control system having a control bar adapted with an internal sheeting system that provides trim / sheeting control by adjustment of outer steering lines which are attached at or near the rear corners of the kite. A tubular control bar is adapted such that the outer steering lines are routed through the interior of the control bar through openings at each opposing end. The outer steering lines are each joined to a sheeting control line which extends back out one of the opposing ends in either a left hand actuated or right hand actuated embodiment. A fixed pin located approximately mid-length within the control bar provides a fixed structure about which one of the outer lines and / or sheeting control line is routed in U-turn fashion. By pulling the sheeting control line from the end of the control bar, the rider can shorten the effective length of the outer steering lines thereby increasing the angle of attack so as to power up the kite. By releasing the sheeting control line such that it is drawn into the control bar, the ride can allow the outer steering lines to fully deploy thereby reducing the angle of attack so as to depower the kite. The control bar is equipped with means for selectively fixing the sheeting control line so as to achieve a desired angle of attack.
