. KITE CONTROL Fil ed Oct. 50-. 1961 INVENTOR. F I 2 RAYMOND L. MECLAIN ATTORNEY United States Patent Ofilice N 3,138,356 Patented June 23, 1964 3,138,356 KITE CONTROL Raymond L. McClain, 3125 Idlewild, Wichita, Kans. Filed (lot. 30, 1961, Ser. No. 149,821 Claims. (Cl. 244-155) This invention relates to kites. More specifically, my invention relates to new kite control means. Still more specifically, my invention relates to a relatively simple and effective single-piece device by means of which a kite can be reeled out, controllably flown, and reeled in.

Various devices to control kites while in flight and to reel kites in and out are known to the prior art but they all suffer from several disadvantages. One of the most common of these disadvantages, and one which makes many of the devices of the prior art impractical for use with childrens kites is the complexity of the control means. Many of these devices have several moving parts, such as reels, cranks, and catches, or having several separable parts such as a handle on which can be mounted a holder for string. These features have the disadvantage of being more diflicult and expensive to make, of being more difilcult to operate, and of being more easily broken. Another difficulty of the devices of the prior art is that the strings are the same distance apart during both the reeling and the flying operations. For greater control during flight, the strings should be relatively far apart during flying but during reeling this control is not necessary and reeling and unreeling proceed slower and with more difiiculty if the strings are wound on two spools, one at each end of a long handle. Wind fluctuations causing the kite to twist and turn increase the difficulty of reeling with the devices of the prior art because they cause tension at each end of the controlling device to change.

These and other disadvantages and diflicutlies of the prior art kite controls have been overcome by my invention. My invention includes a movable member constructed in the end portions to receive means to connect the movable member to a kite, commonly string, which is attached thereto in spaced relation during the kite flying operation. Means are provided with the movable member which define a central spool prtion which receives the preferred string means during winding and unwinding operation and during periods of non-use. The means defining the spool portion preferably have means therewith constructed to removably receive and hold the preferred string means during initial winding operation and when all the string has played out. In addiiton, or as an alternative, means can be provided to automatically release the string means from the spool portion of the member when all of the string means is unreeled in kite flying operation.

In a preferred specific embodiment of the invention, my new kite control means includes an elongated rod of plastic material which is of size to be easily gripped in the hands of the user. The rod has a centrally located cylindrical portion and end portions tapering therefrom, the end portions being of equal size and of like size with the cylindrical portion. A shallow groove is provided near each end portion which forms a knob and the groove receives string means in operation. Two circular discs or flanges are provided and positioned at the ends of the cylindrical portion of the rod and planes generally perpendicular to the axis of the rod and such define a spool portion. Each of the discs preferably has a straight slot therethrough extending tangentially along thedisc from the radially outer surface thereof to the surface of the rod to receive and hold the string means. Preferably, two strings are provided and attached in one end portion in the grooves and are attached in the other end portion to opposite sides of a kite or the like. When all the string is played out, the kite is flown with the strings extending from the grooves and during reeling and unreeling operations as well as during periods of non-use the string is placed in the slots and then wound around the spool portion of the device.

It is an object of this invention to provide new kite control means.

It is another object of this invention to provide a one piece kit control means by which the distance between the ends of the strings on the control means holding the kite can be varied between reeling operations and the flying and controlling operations.

It is still another object of this invention to overcome the various disadvantages of the kite controlling means of the prior art.

Another object is to provide relatively inexpensive and easy to construct kite control means.

Other objects and advantages will become apparent to those skilled in the art upon reading this disclosure.

Drawings accompany and are a part of this disclosure. These drawings depict a preferred specific embodiment of the new kite control structure of my invention, and it is to be understood that such drawings are not to unduly limit the scope of my invention.

In the drawings,

FIG. 1 is an isometric view of a preferred specific embodiment of the new kite control means of my invention shown with the string or cord in reeling or unreeling position.

FIG. 2 is a perspective view of a preferred specific embodiment of the new kite control of my invention attached to a kite, with the string or cord completely unreeled and the kite flying.

FIG. 3 is an enlarged longitudinal cross section view of the preferred specific embodiment of the new kite control shown in FIGS. 1 and 2 with the string or cord removed, taken along the line 33 in FIG. 4.

FIG. 4 is a transverse cross section view taken along the line 44 in FIG. 3.

The following is a discussion and description of the new kite control structure of my invention made with reference to the drawings whereon the same reference numerals are used to indicate the same or similar parts and/or structure. The discussion and description are of a preferred specific embodiment of the new kite control structure of my invention, and it is to be understood that such is not to unduly limit the scope of my invention.

Referring now to the drawings in detail, the kite control shown generally at 10 is a preferred specific embodiment of the new kite control of my invention. It includes a rod or the like 12 having a generally cylindrical center portion 11, and two

tapered end portions

13 and 15 having

knobs

14 and 16 at the extreme ends thereof which are formed by

shallow grooves

17 and 19, respectively. Two discs or projecting

flanges

18 and 20 are provided andare preferably integral with rod 12 and preferably positioned at the ends of the cylindrical portion 11. Discs or

flanges

18 and 20 are positioned along rod 12 so that the flat surfaces of the discs or flanges are in planes generally perpendicular to the axis of rod 12, and are spaced along rod 12 so that the distance from knob 14 to disc 18 is equal to the distance from knob 16 to disc 20. This is desirable since a centrally located spool portion as defined by

discs

18 and 20 and cylindrical center portion 11 facilitates the reeling and unreeling operations described hereinafter. The rod 12, together with the

discs

18 and 20 can be molded as one piece, out of a suitable material such as plastic, and the like, or they can be separately formed and the discs mounted on the rod 12 in any suitable manner, such as by fusing the parts together, by cementing, gluing, etc. The rod 12 can be machined or formed from other materials such as wood, hard rubber, or synthetic rubber, suitable metals, and the like.

Discs

18 and 20 have

slots

22 and 24 cut or otherwise formed therein. The

slots

22 and 24 are preferably in a line tangent to the circular cross section of rod 12 and are preferably generally parallel to each other. The

slots

22 and 24 preferably extend from the outer edge of the discs to the surface of rod 12. Two strings or

cords

26 and 28 are provided and one end of each of

strings

26 and 28 is tied or otherwise secured in

grooves

17 and 19, respectively, and the other end of each of

strings

26 and 28 is fastened to opposite ends of a frame member or cross piece 29 of a kite 36. Kite 30 is a common kite, having

perpendicular cross members

29 and 32, made of wood, plastic, metal or the like, and covered with a wind catching sheet of material 34 such as paper, plastic, and the like. The kite control of my invention works very well with the kite described and illustrated in the drawings and can also be used with other types of kites.

The operation of the kite control of the invention is as follows. When the kite 30 and the kite control are being stored or the

strings

26 and 28 are being wound or unwound, the kite control appears as in FIG. 1, with the strings or cords 26 and 2S wrapped around the center or spool portion 11 of rod 12. When it is desired to fly the kite 30, the

end portions

13 and 15 of rod 12 are grasped with the hands and the kite control 10 is turned about its own axis in a direction to play out the string. When the strings are completely unwound, they are removed from

slots

22 or 24. These slots are preferably cut tangentially rather than radially, so that the strings are wedged or urged to the bottom of the slots and are not removed except by a deliberate action, and so that when the strings are inserted in the slots they will not accidently slip out of the slots. Because the slots are cut tangentially, they act as automatic removal means, that is, when the string is unwound, the pull from the kite causes the strings to slide out of the grooves. With

strings

26 and 28 removed from

slots

22 and 24 as shown in FIG. 2, kite 30 can now be easily controlled by twisting or turning the kite control 10, with one hand if desired. When it is desired to reel in the kite 30, the two

strings

26 and 28 are inserted in the

slots

24 and 22 respectively and kite control 10 is manually turned about its axis to reel in the kite. The tangentially cut slots act to hold the strings and descrease the chance of their sliding out during winding operation.

The overall size and dimensions of kite control 10 can vary widely and are preferably such as to be easily gripped by the user. The radius of discs 18 and and the length of the central cylindrical portion 11 depend on the size and length of the

strings

26 and 28 which are wound thereon. The length of rod 12 depends on the degree of control desired.

As will be apparent to those skilled in the art, various changes and modifications of the preferred kite control structure disclosed herein can be made or followed without departing from the spirit of the disclosure or from the scope of the claims.
