Filed Dec. 1, 1954 3 Sheets-Sheet 2 United Star- This invention relates to kites and more particularly to an improved form of kite which exhibits very satisfactory flying characteristics.

In my Patent No. 2,588,293 of March 4, 1952, there is disclosed a kite which may be formed of heavy paper or the like and simply assembled from a single flat piece of such material. Such a kite provides a very inexpensive flying device which may be shipped conveniently and easily prepared for flight by a user having but little skill. The present invention constitutes an improvement over the kite disclosed in that patent.

An object of the present invention is to provide an improved lightweight kite formed of paper board, thin aluminum, or the like, and which exhibits increased stability and flyability.

It is also an object of my invention to provide a construction and design equally effective in kites varying in size from very small to large.

Another object is to provide a kite to which the flying string may be simply and accurately attached to promote stable flying.

Still another object of the invention is to provide an improved kite composed of lightweight material which may be successfully flown in a substantial wind.

A feature of the invention is the provision of an improved kite, having air escape apertures and tabs extending partially thereacross to promote increased flight sta bility and balance.

Another feature is the provision of an improved kite with simplified means for attachment of a flying string including a stiffening strut disposed on one side of the body with an integral tab portion extending through a slit in the body to provide a single tie point for flying string.

Still another feature of the invention is the provision of means to improve flyability of the kite including a twopiece tail section integral with the body of the kite but yieldable in a vertical direction wtih respect to the body.

Further objects, features and advantages will be apparent upon consideration of the following specification and drawings, in which:

Fig. 1 is a perspective view of the completely as sembled kite as it appears in flight;

Figs. 24 are plan views of the components of the kite illustrating the shapes and the folding lines thereof;

Fig. 5 is a back view of the kite;

Fig. 6 is a sectional view along the lines 6-6 of Fig. 5;

Fig. 7 is a sectional view along the lines 7-7 of Fig. 5;

Fig. 8 is a sectional view of the tail member along the lines 88 of Fig. 1; and

Figs. 9 and 10 illustrate flight of a plurality of kites from a single flying string.

Fig. 1 illustrates the flying position of the kite 10 with its associated tail anchors or members 11 and the flying string 14. As mentioned, the kite may be made of some light weight material such as heavy paper, cardboard, or

2,811,327 Patented Oct. 29, 1957 tail members may be used in accordance with the strength of the prevailing winds.

As shown in Figs. 1 and 2 the kite consists of the circular body 16 with a sector 17 thereof doubled upon itself and secured in the form of a tuck 18 (Fig. 1) to provide a body of a saucer-shape or the shape of a very wide base cone. As is apparent, the tuck 18 provides a keel for the kite. A suitable metallic clip 19 may be used to secure the tuck 18. In order to provide a neater construction of the saucer-shaped body, a triangular portion 20 at the "apex of the sector may be removed entirely. Surrounding the major portion of the body 16 is an integral reversely bent edge or rim 21 which enlarges-into tapered tail sections 23 and 24 which terminate on opeven light weight metal or plastic. Additional or fewer posite lines defining the limits of the sector 17. The tail sections each have flaps or tabs 26, 27 at the extreme ends thereof so that a string or thread 28 may secure the tail portions 11 thereto. It should be pointed out that the tail sections 23 and 24 are rather flexible since the tuck taken in the body 16 does not extend beyond the circular'limits thereof and the sections have a tapered shape. This promotes stability and balance during flight.

At the scored juncture line 30 between the body 16 and the rim 21, the rim is reversely folded in relation to thedish shape of the body 16. Therefore, asthe kite is flown as shown in Fig. 1 with the convex side thereof facing the wind, the reversely folded rim 21 will act as a'wind catcher for the kite. Moreover, in order to further stabilize the kite, tabs 33, 34 and 35are out from the body 16 and left integral with the rim 21. Accordingly, as the rim 21 is reversely folded, the flaps or tabs 33, 34 and 35, not having been scored atline 30, turn with the reverse fold of the rim and remainin a plane therewith. This is clearly illustrated in Figs. 6 and 7. The apertures in the edge of the body 16, with the flaps partially thereacross, constitute escape apertures for the wind and greatly improve the'flyability of the kite.

A slit 38 is cut in the body 16 at a point slightly beyond the center of the circular body and opposite the triangular portion 20 so that a stiffening strut 40 may be supported therein (Figs. 57). Small apertures at the ends of slit 38 prevent tearing of body 16. The strut '40 is shown in Fig. 4 and preferably consists of a piece of the same material of which the kite is formed doubled upon itself at line 41 to form roughly a triangle with a tab 42 at the apex thereof. The tapering sides of the strut 40 are formed to correspond substantially with the contour of the interior of the saucer-shaped body 16 so that it assists in maintaining such shape. The tab 42 is inserted through the slit 38 to project from the convex side of the body as a tie point to which the flying string 14 may be attached by means of aperture 43. The strut 40 is an important feature of the present invention and aids greatly in maintaining the kite body in its intended shape as well as providing a very simple means for attachment of the flying string. Thus it may be seen that the string is attached at a single point upon the kite and that there is virtually no opportunity for unbalanced pull of the string such as might occur if the string Were attached to the kite at more than one point. Strut 40 in effect provides automatic centering for the string 14. It is doubled upon itself to provide increased stiffness and to better engage the kite body.

Tail member 11 is shown in its unfolded condition in Fig. 3 and it may be seen to consist of a piece of light weight material folded at lines 49 in the form of a pyramid. Tab 50 may be inserted in a slot 51 in an extension 53 of one side of the pyramid in order to lock the article in its intended shape (Fig. 8). An aperture near the apex of the tail member may be provided for. attachment of the tailstring 28. This string may be tied and brought down through the pyramid and out the bottom to permit attachment of further tail members as shown in Fig. 1. It may be preferable to form the tail pieces of material of somewhat lighter weight than that of the kite itself in order to prevent undue drag thereupon, particularly when the wind is light. However, stabilization of the kite may also be effected by using the proper number of tail anchors or members as previously mentioned. It is also possible to form the tail members in conicai shape by omitting score lines 49.

The perspective view of Fig. 9 and the sectional view of Fig. 10 show the method of grouping a plurality of kites for flight from a single flying string in what may be termed tandem style. The first kite 10 is flown as previously described by means of string 14 and a second kite 10a is secured to kite 10 by means of a short joining string 6%). At an aperture 43a in the strut 40a one end of string 60 is attached while the other end thereof is secured to an aperture 62 in the strut 40 (Fig. 10). The two kites may then be successfully flown as shown in Fig. 9. One or more additional kites may be similarly added by attachment to the joining string 64 which is fastened to strut 40a.

It may be seen that the kite of the present invention can be very inexpensively manufactured and conveniently shipped due to the type of material and the simply formed shapes of the parts as well as the unassembled flat condition thereof. In addition, assembly of the completed device is relatively easy and may be eifected with little likelihood of failure. The assembly involves very simple folding and fastening operations which practically insure a successful flying device.

It is also noteworthy that the flying string attachment point, the tuck or keel, the tail sections and the attached tail members are all auomatically in alignment to promote stability of flight. Furthermore, in actual tests the kite as described has proved highly successful due to the improved balance as provided by the air escape apertures and associated tabs, as described above. Of course, the strut which provides the point for string attachment also strengthens the entire assembled kite so that it may better withstand stronger winds. It may also be pointed out that kites have been constructed in accordance with the invention in Widely varying sizes from one as small as six inches across to one which is several feet across. The invention provides, therefore a highly satisfactory kite structure.
