KITE

Filed June 25, 1955 IN VEN TOR,

BY Mia]; [UHuisazg fiTTORNEV United States Patent KITE Alton W; Hutson, Richmond, Calif.

Application June 23, 1955, Serial No. 517,431

4 Claims. ((31. 244-153) The present invention relates to improvements in kites and has particular reference to kitesmade in the manner of a parachute or umbrella.

In order to make a kite of this character fly successfully, it becomes necessary to arrange the control element in such a manner that they hold the umbrella-shaped body at a tilt with respect to the direction of the wind, so as to produce a proper lifting eflect.

It has been proposed heretofore to obtain the desired effect by means of struts and rigid members incorporated in the device, but the provision of such members tended, of course, to increase the weight of the kite, and furthermore interfered with the packaging of the kites, since the latter could not be confined into a small space.

In the present invention, it is proposed to provide a kite of the character described, with control elements consisting exclusively of flexible strings, so that the entire kite can be readily folded into a small package, such as might be conveniently carried in a pocket of the user.

It is further proposed to arrange the flexible control elements in such a manner that they still cause the body of the kite to assume the desired tilting angle with respect to the direction of the wind.

Further objects and advantages of my invention will appear as the specification proceeds, and the new and useful features of my kite will be fully defined in the claims attached hereto.

The preferred forms of my invention are illustrated in the accompanying drawing, forming part of this application, in which:

Figure 1 shows a perspective view, taken from the side of my kite while in flight;

Figure 2, an end view of the kite as shown from lines 2--2 of Figure 1;

Figure 3, a view similar to that of Figure 2, and illustrating a modified form of my invention, following the same principle; and

Figure 4, a view similar to that of Figure 1, and illustrating another modified form of my invention.

While I have shown only the preferred forms of my invention, it should be understood that various changes or modifications may be made within the scope of the claims hereto attached, without departing from the spirit of the invention.

Referring to the drawing in detail, and first to the form shown in Figures 1 and 2, my kite comprises in its principal features, a parachute-like body 1, a draw-string 2 attached to the body portion in the center thereof, as at 3, and a number of shroud lines 4 secured upon the rim of the body at spaced points and connected to the drawstring at a point spaced from the body, as at 5.

The body is constructed of flexible, plastic material of any suitable type, and, in my preferred form, is made of a sheet of material approximately thirty-six inches in diameter.

In the manufacture of my kite, the rim, shown at 6, is drawn in and suitably seamed to produce a substantially semi-spherical body, as shown.

The axial center-line of this hollow body is indicated by the line 7. The draw-line 2 is attached to the body at the axial center-line, .and is formed, at its, free end, with a loop 8 for attachment of the conventional type line'9.

The rim of the hollow body is secured to the draw string by means of the shroud lines 4, which are arranged in such a manner as to impart a desired angularity to the body when in flight as compared with its axis 7.

For this purpose, I divide the rim into eight sections,

providing eight equally spaced points of attachment for the shroud lines. Any one of these eight points may be selected to serve as the upper center of the'rim.

Assuming that the point a has been selected for this purpose, it is connected to the draw-string 2 by the first shroud line 4. Proceeding in opposite directions to the next two points of attachment, b, they are connected to the point 5 by the next pair of shroud lines 4.

Proceeding further, the next two points of attachment marked 0 are secured to the point 5 by the shroud lines 4", and the last pair of points of attachment marked a are attached to point 5 by the shrould lines 4".

The last point of attachment, marked e, which is directly opposite point a, is not attached to any shroud line, so as to leave the lower portion of the hollow body relatively free for flexing purpose. This point is used, however, for attachment of the tail, indicated at 10.

The shroud lines are dimensioned to progressively increase in length from the starting point a to the last point d, so as to cause the hollow body, or parachute, to naturally assume an angular position with respect to the draw string when the latter and the shroud lines are drawn tight while the kite is in flight.

This angle is marked at 11, and should preferably be about twenty-two degrees. In my preferred kite, now in use, I make the first shroud line 4 about seventeen inches long, the two next lines 4' approximately the same length, the two succeeding ones 4", about eighteen inches in length, and the last two lines 4", about twenty-one inches in length.

The last shroud line, as has been stated, is omitted, but if it were applied, as shown in Fig. 4, it would be approximately twenty-nine inches in length as indicated by the reference character 20, because, in actual flight, the tail end flattens out considerably to allow the wind to spill out and to provide a lifting effect for the hollow body.

It will thus be seen that, when in flight, the parachute will naturally assume an angle of about twenty-two degrees with respect to the draw-string, which places the body of the kite at a tilt with respect to a perpendicular plane, sutncient to allow the wind to produce the desired lifting effect.

A similar effect may be obtained by the arrangement illustrated in Figure 3, in which the shroud lines 14 are all made of the same length, and the point of attachment for the draw-string 2 is shifted from the central point to a point spaced therefrom sufliciently to again produce the desired angle of twenty-two degrees between the axis of the hollow body and the draw-string when the kite is in flight.

It will be seen that in either case, the entire kite is completely flexible, except for some minor attaching fixtures, and can be readily folded into a small package.

While my kite is naturally intended principally for a toy, it can also be used as a signalling device, or for many other purposes, one being, for instance, that of a scarecrow for birds and animals.

My kites can be flown in light wind, as well as in strong winds, and need no running to get it into flight position.

I claim:

A kite comprising a flexible body of generally circular shape, a plurality of shroud lines attached to the periphery of said body in circumferentially spaced relation to each other, there being-ta main shroud line attached totonerpoint. on.thei.periphery of said .body with-referenceto which. all of; the=-remainiiig 'slirould'liii'esf are longer, said remainiiig shmudr lines eonsi'stin g of a plu-f rality of pairs, of lines;..witliltlie,.lines.bfieaeh pair'b'eingfl of equal length and with successive pairs being progres;
