  • Patent number: 6062510
    Abstract: A kite includes an arrangement of elongate, flexible rods interconnected at one or more joints to define a frame structure. A primary tensioning system provides a reactive force, in response to a wind force exerted on the frame structure, to thereby increase frame rigidity and resistance against bending and breaking of the rods. Secondary tensioners absorb the wind force and provide resistance against deforming of the frame structure when under stress. A net, secured to the frame structure by the secondary tensioners, extends across a front face of the kite. The net, having an open weave construction, provides no resistance to wind forces. One or more panels, formed of a thin film material, such as lightweight fabric or plastic, are selectively and removably positionable on the front face, against the net; the panels being impervious to air flow and thereby defining a wind confronting surface for providing wind resistance.

  • Patent number: 5556057
    Abstract: A controllable kite, which changes its geometry and aerodynamic form in flight, in response to control inputs from control handles and control lines, enabling smooth stable high-speed flight as well as extreme low-speed agility and the ability to fly in any direction or hover, consists of a flexible leading-edge spar, stressed by the curve of the sail and providing tension in the sail. Control longerons, at a predetermined angle on either side of the centerline act on the leading-edge spar in such a way as to provide variable geometry that controls the form, stability and flying characteristics of the kite and sustains the shape required for both high and low-speed flight. Precise control is achieved by attaching equal-length control lines from control handles directly to the control longerons without the need for bridling.

    Abstract: A wind powered system utilizes a free-flying airfoil tethered to a conveyance device such as a water ski, a skegged hull slab or a wheeled land vehicle which either defines or inherently has tracking means defining a preferred traverse vector across an underlying surface. The tractive force of the airfoil is applied at the center of lateral resistance of the conveyance device such that there is no destabilizing moment caused by the airfoil, thereby removing an artificial limit on the sail area that is imposed upon fixed mast sailing craft. A control bar provides a mount for a tether reel which enables the conveyance device, when same is a kite, to be launched from the water without requiring the assistance of a boat.

  • Patent number: 5033698
    Abstract: The curve profile of the front edge of an air-filled wing or sports kite of a type which is guided from the ground is maintained without the use of any bracing system. This curve profile, which is very important in determining the flight characteristic of the wing, is controlled exclusively by adjusting the various lengths of balance lines. Two symmetrical line bundles or connecting balances radiate from end points of at least two steering lines and are fastened to various points on the wing base. If so desired, central balance lines can be connected to the wing base without intermediate fastenings. The fastening points on the wing base are located chiefly at the front portion of the wing base. The lengths of the various balance lines preferably increase from the side edges to the middle. However, the rate at which the balance line length becomes greater can increase, decrease, or remain constant, at least in certain areas.

The kite is provided with an article holding and releasing means consisting of a flexible-walled pocket, usually forwardly-opening, which is closed by the tension on the kite string to hold the article in the pocket during launch and flying. Upon release of the tension the pocket tends to open, assisted by entry of air into the pocket by the kite's forward motion, and the kite stalls and tips forward under the forward location of the article until the article is released. Alternatively, or in addition the holding and release means are flexible parallel straps cooperating with the keel, or a separate pocket. A weight is provided at the point of attachment of the kite string to the body and cooperates with the pocket to produce a swooping, gliding decending motion of the kite upon release of the tension.

  • Patent number: 4846424
    Abstract: A ram-air airfoil stunt kite has its upper forward edge provided with two stiffener members that provide a rounded leading edge and are connected together by a flexible joint. Two operator-held control strings are connected to bridles which are, in turn, connected to keels on the kite. The outboard bridle strings are shorter than the inboard bridle strings so as to remain taut during normal flying operations. When the apparent wind velocity increases, the kite becomes transversely curved, whereupon the inboard bridle strings become taut to establish an optimum maximum curvature.

  • Patent number: 4842222
    Abstract: A load carrying and releasing pendular device for attachment to a kite string and release the load on jerking on the kite string. The device is fixedly attached to the kite string at an upper location. The device is also releasably coupled to the kite string at a second lower location. The kite string is releasable from coupling to the device at the second location by jerking on the string of the kite. The device assumes a first raised position when it is coupled to the kite string both at the first upper location and at the second lower location. On jerking the kite string, the string becomes released at the second lower position and the device pivots from the first raised position to a second lower position. This pivoting of the device, providing movement of portions of the device, relative to the kite string causes the release of the load releasably carried by the device.

  • Patent number: 4821976
    Abstract: A dual reel string winding and unwinding apparatus for us with stunt kites including a first spool and a second spool, each having two pairs of aligned holes extending through flanges therein. A first and second pair of posts extend through the aligned holes in the first and second spools to cause such spools to rotate together. A connector, having an axle thereon, is connected to the first and second posts and a handle is rotatably mounted on the axle of the connector. One of the posts extends far enough through both spools that it can be utilized as a handle so that by grasping the handle on the axle and the handle on one of the posts, the two reels can be rotated simultaneously together in either direction. A guide is connected to the handle on the axle and is disposed radially outwardly from the spools so as to guide the string either onto or off from the proper spools.
