CHRISTOFFEL 7 7 /71/22 AT CsRNEYs KITE STRUCTURE The present invention relates to an improved keeltype kite which can be controlled from the ground for specific maneuvers.

An object of thepresent invention is to provide an improved keel-type kite which can be controlled in maneuvering from the ground by a pair of lines.

Another object is to provide an improved keel-type kite having a keel whose position is controlled from the ground to control the maneuvering of the kite.

A further object is to provide an improved keel-type kite which is connected by a pair of lines to a control member which may be used to control the maneuvering of the kite and on which the lines may be wound when the kite is not in use.

BRIEF DESCRIPTION OF THE DRAWINGS These and other objects and advantages of the present invention are hereinafter set forth and explained with reference to the embodiments illustrated in the drawings wherein:

FIG. 1 is a perspective view of the preferred form of kite of the present invention in flying position.

FIG. 2 is a bottom plan view of a keel-type kite having a modified control connection.

FIG. 3 is a bottom plan view of another form of keeltype kite illustrating its control connection.

FIG. 3 is a partial detail sectional view of the control connection of the kite shown in FIG. 3.

FIG. 5 is a view of a combination control member and line holder with the control lines wound together around the two legs of the holder.

FIG. 6 is a view of the combination control member and line holder with each of the control lines wound around the leg to which it is attached.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The kite 10 illustrated in FIG. 1 is a keep-type kite having a body 12, a keel 14, control lines 16 and 18 connected from the keel control rod 20 to the control member 22 and suitable means such as wing sticks 24, keel stick 26 and cross brace 28 to maintain the body 12 in extended flying position. The keel 14 is generally triangular in shape and has the larger of its angles with the keel positioned forward. The control rod 20 is connected to the keel 14 at or near the normal point of attachment of the flying line when no control lines are used. The control rod 20 is connected to the keel at its center point and the lines 16 and 18 are connected to the ends of control rod 20. The lines 30 and 32 connect from the respective ends of the control rod 20 to the body at positions near the juncture of the wing sticks 24 and the cross brace 28.

In the form of control rod 20 illustrated in FIG. I, the rod 20 may be of any material so long as the rod is relatively stiff. In one kite actually flown the control rod 20 was formed from a relatively stiff wire. A wood stick of suitable strength and rigidity also may be used.

In the modified form of the invention illustrated in FIG. 2, the kite is similar to the kite shown in FIG. I and therefore has the same numbers assigned to the same parts. The kite of FIG. 2 however has a modified connection from the control rod 34 to the .keel and body of the kite. The lines 16 and 18 are connected to the ends of control rod 34 and the strings 30 and 32 extend from the ends of control rod 34 to the body 12 at cross brace. Further the lines 36 and 38 extend from the ends of control rod 34 to the normal point of attachment for the flying line. With this type of harness connecting the control rod 34 to the body 12, the movement of the control lines 16 and 18 control the maneuvering of the kite 10.

In FIGS. 3 and 4, another modified form of control system for another type of keel kite is ilustrated. The kite 40 includes the body 42, the keel 44, wing sticks 46, keel stick 48 and the cross brace 50. The control system for the kite 40 includes the two control lines 52 and 54 extending to the opposite ends of the control rod 56 which is secured at its center point to the usual point of string attachment on the keel 44. Additionally, the brace 58 extends from the ends of control rod 56, at least partially surrounds the keel stick 48 at the base of the keel 44, and extends through keel 44 as shown. The structure of brace 58 is best seen in FIG. 4. If desired, the brace 58 may be considered to be two braces extending from the opposite ends of the control rod 56 and engaging the body 42 at the base of the keel 44.

The control member and line holder 22 is detailed in FIGS. 5 and 6. The member 22 is generally C-shaped and includes a body 60 which is adapted to be held in the hand of the person flying the kite, and includes two legs 62 and 64 which extend from the body 60 and terminate in enlarged ends. Each of the legs defines an aperture 66 through which the end of the line to be attached thereto is secured. The lines may be wound around body of the legs 62 and 64 as shown in FIG. 5, or each line may be wound around the leg to which it has been secured as shown in FIG. 6. With the winding as shown in FIG. 6 the kite may be controlled during the unwinding of line from the member 22 because the enlarged ends of the legs allows the unwinding of the line to be controlled to thereby allow either of the lines to be pulled to control the kites flight.

From the foregoing it can be seen that the improved kite and control system of the present invention allows the person flying the kite to easily control the maneuvering of the kite from the ground by manipulating the lines leading to the kite. Each form of the kite includes a control rod which is connected with the kite in such a manner that the relative position of the keel to the kite body may be changed to cause movement of the kite during flight'in a desired direction. Also, the control member and line holder is provided which may be used for easy and simple control of the kite maneuvers and also on which the control lines may be wound.

What I claim is:

1. A kite, comprising a body,
