INFLATABLE KITES Filed April 24. 1961 2 Sheets-Sheet 2 F |G 8 INVENToR.

, THEoDoRE HYMAN ATTORN EY United States atent 3,686,737 INFLATABLE KiTES Theodore Hyman, 16%67 Green J alley Drive, St. Louis County, Mo. Filed Apr. 24, 1961, Ser. No. 105,021 7 Claims. (Cl. 244-153) This invention relates in general `to certain new and useful improvements in kites and, more particularly, to an inflatable kite.

It is conventional practice to make a kit by fabricating a framework of light wooden members held together by string .and then covering the framework with light paper or cloth. However, a slight deviation from the correct shape, size or form will materially reduce the aerodynamic efliciency of the kite and, as a result, it is a quite common experience that kites made in this manner often do not liy well or sometimes will not ily at all. Furthermore, conventional kites, even when well made, are diflicult to control and are subject to freakish air currents and Winds which may cause a kite to dive suddenly into trees, power lines, roof tops and similar obstructions. When this occurs, the kite is usually abandoned since it is difficult and often `dangerous, to retrieve it from such a precarious or hazardous location. Moreover, conventional kites, being made of a thin Wooden frame, are rather fragile and will often break apart under the slightest adverse circumstances.

Another common problem which is encountered with conventional kites arises from the fact that kites cannot usually be disassembled. In fact, most types of kites must be carried about from place to place and stored between periods of usage in fully set up condition. Since most types of kites are both bulky and fragile, this problem is rather difcult to overcome. In fact, most young boys, who expend considerable effort -in making a kite during the Spring season of one year and y it sucessfully without loss or breakage, will put the kite away after the kite season is over and, upon returning to it later on, will lind to their dismay that the kite has been damaged or broken during the period of storage.

It is, therefore, the primary object of the present invention to provide an inatable kite constructed of flexible sheet material of the synthetic resin type.

It is also an object of the present invention to provide a kite of the type stated which can be folded or rolled up into a relatively small package for storage, shipment, and similar handling.

It is a further object of the present invention to provide a kite of the type stated which can be readily inated and, when so inflated, will assume a selected shape which is aerodynamically efiicient.

lt is another object of the present invention to provide an inflatable kite of the type stated which can be made in a variety of shapes and colors.

It is an additional object of the present invention to provide a kite of the type stated which is rigid and sturdy in construction and economical in cost.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement and combination of parts presently described and pointed out in the claims.

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, A `designates .an infiatable kite consisting of a somewhat triangular at bottom member 1 formed preferably from a heavy-gauge sheet of thermoplastic synthetic resin, such as polyethylene -or polyvinyl chloride. The bottom member 1 is procided with an arcuately-shaped forwardly presented margin 2 and a substantially straight rearward margin 3 connected by two rearwardly converging side margins 4, 5. Moreover, the lbottom member 1 may be said to have an upwardly presented face 6 and a downwardly presented face 7.

Disposed in at overlying relationship upon the surface 6 of the bottom member 1 in symmetrical relation along the longitudinal axis thereof is a similar plastic sheet 8 which is die-cut or otherwise suitably formed so as to linclude a long narrow central body section 9 which is provided at its forward end with an enlarged head portion 1t) and two laterally and forwardly extending arm sections 11, 12, which are curved slightly forwardly at their outer ends in the provision of leading tips 13, 14, respectively. At its rear end, the body section 9 is integrally provided with outwardly land rearwardly diverging leg portions 15, 16, which are substantially shorter than the arm sections 11, 12, and are disposed at an acute angle with respect to each other. The sheet 8 is secured around its entire peripheral margin by a continuous heat-sealed seam 17 so that the area `between the bottom member 1 and the sheet 8, which is enclosed within the seam 17, will constitute an air-tight enclosure.

Heat-sealed or otherwise secured in air-tight relation within the bottom member 1, preferably along the longitudinal axis of the body section 9 and toward the forward end thereof, is an air valve 18 integrally including an annular :ange 19 by which the valve 18 is eat-sealed to the bottom member 1. Formed integrally with, and extending across the central area of, the annular ange 19 is a flexible diaphragm 20 which is centrally provided with a depending air-inlet tube 21 having a downwardly projecting pull-tab 22. In its normal or valve-open position, the diaphragm 20 curves downwardly and outwardly in somewhat lenticular form and the air-inlet tube 21 projects axially outwardly therefrom substantially as shown in FIG. 4. Also integrally formed upon the opposite or interior face of the flange 19 is a series of uniformly spaced inwardly converging, relatively rigid arms 23 which merge into the periphery of a relatively rigid liat closure disk 24. It will be apparent that the user may place the air-inlet tube 21 between his lips and blow therethrough and air will pass through the openings between the arms 23 into the airtight enclosure formed between the bottom member 1 and the sheet S by the seam 17, thereby inflating the kite A. As `the kite A is inflated, the entire central portion will be longitudinally stiffened and the laterally extending portions of the enclosure in the region of the arm sections 11, 12, and leg sections 15, 16, will also be inflated and thus stittened. In such inflated position,

the .kite A will be, in dieet, .subdivided im forward aileron sections 25, 25, lateral wing-'forming'sections27, 2S, and a tail-Hap 29. As soon as lthe kite A has been fully inflated, the'Vair-inlet tube 21 may be pushed axially inwardly, Vtelescoping the diaphragm so that the interior end of the v air-inlet tube 21 will be securely held in endwise abutting relation against the closure disk 24. As a result, air cannot'escape through the Yair-inlet tube l2,1 and the kite A will remain inflated.

The bottom member 1 is provided along its longitudinal axis with forward and rearward eyelets 30, 31, which are respectively located yadjacent the forward and rearward margins of the body section 9. The user may insert a loop of the kite string l1 through these eyelets 3i), 31, and knot the end so as to retainit therein and attach a length .of kite Vline l2 thereto substantially as shown in FIG. l l. Thereupon, the inflated kite A may be launched and -will iiy in an extremely eicient manner.

It will, of course, be obvious that the design of the she/et ,8 may be changed within limits to represent the figure of a bird, an airplane, or any other figure. For example, .the leg portions 15, 16, could be extended outwardly at various angles and still maintain adequate aerodynamic efciency to render the kite stable in flight. The wings andrbody portion are formed with suiicient material sol that they may be manually raised or lowered, as shown in FIG. 9, vand the excess material gathered at a point adjacent the body portion, as illustrated in FIG. 8. The kite will, however, remain in either such adjusted posities- `It should be understood that changes and modifications in the form, construction, arrangement, and combination of the lseveral parts of the inflatable kites may be made and vsubstituted for those herein shown and described without departing from the nature and principle o f my invention. Y A Y AHavingl thus described my invention, Vwhat VI claim and desire to secure by Letters li'atentis:l
