Cramer Mahan, Dayton, Gino Filed Feb. i7, 1961i, Ser. No. 9,295 6 Claims. (Cl. 244-154) This invention relates to a novel kite.

Kites have been fabricated through the ages in many shapes and forms and from a great variety of materials. In general their etliciency has been relatively low. It has always been diiiicult for the average person to get a kite into the air, let alone keep itrin the air once it is up. Wind velocity and direction must be extremely favorable in order to fly a conventional kite with any degree of success. l

The present invention provides a novel kite which will function quite efficiently, even under conditions of relatively minimum wind velocity. Its components are so formed and so related that it can be readily-launched and will inherently stabilize itself in flight. Moreover, the

kite in accordance with the invention will function ad mirably under the influence of shifting air currents of a significant nature. tion are fabricated of a foamed plastic such as Styrofoam, the properties of which can be advantageously employed to effect a unique kite.

A primary object of the invention is to provide an improved kite which may be economically fabricated, more eiiicient and satisfactory in use and extremely durable in character.

Another object of the invention is to provide a novel kite the components of which are so related as to facilitate getting the kite into the air. J

A further object of the invention is to provide an `irn proved kite fabricated of a foamed plastic material which can be flown in relatively high winds. v

An additional object of the invention is to provide an improved kite having the general configuration of a glider which will inherently adapt to shifting air currents in ight.

A further object of the invention is to provide a kite which can be iiown under conditions of minimum wind velocity.

A further object of the invention is to provide a kite possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein mentioned.

FIG. 7 is a top plan view of the kite of FIG. 5.

Like parts are indicated by similar characters of references throughout the several views.

The invention embodiments disclosed herein are prefably fabricated from thin sheets of a foarned plastic material such as Styrofoam and shaped to resemble a glider. That illustrated in FIGS. 1-4 of the drawings comprises a body 1, a pair of

wing elements

2 and 3 and an adapter 4.

The body l is tiat in a transverse sense, has the shape of an airfoil in elevation and includes a vertical stabilizer 5 at its ltail end. The body l also has a flatly arcuate- Slot 5 therein which runs generally parallel to its upper surface from a point adjacent its nose 7v to a point adjacent but short of its stabilizer 5.

The

wing elements

2 and 3 are inherently resilient and flexible. The have mating end portions rectangularly notched at their leading and trailing edges to dene shoulf central recess in the end of Wing 3 bounded by relatively.

projected portions to either side formed to accommodate and mate with the

portions

12 and 13 of wing 2. Each of the relatively projected portions of themating ends of thawing elements has an aperture 14 therein. The apertures 1d are uniformly spaced in a manner and for purposes to b e further described.

The adapter d consists of a short relatively thin sleeve which is inserted in and conforms to the shape of the slot 5 to thereby deiine a reduced passage 15 generally concentric therewith. The length of the adapter sleeve 4 is sufficient to cause its respective ends to project moderately from opposite sides of the body 1. The width of the sleeve is slightly greater than the length of the slot 6. Accordingly, notches 16 are centrally disposed in opposite side portions of the sleeve to accommodate the portions of the body l which define the ends of the slot. The mounting of the sleeve to the body 1 is enabled by its inherent resilience and provides a relatively fixed relation thereof in a manner believed` obvious.

As may be seen with reference to FlGS. 2 and 4 of the drawings, the adapter 4 has three uniformly spaced apertures 17 in the upper portion of its laterally projected posed to the other side of the body 1.

The projected

extremities

16 and 11 of the

wing elements

2 and 3 are nested in the respective endsv of the passage 15 defined by the adapter 4 in coextensive abutting relation. The shoulders 9-t'o-either'side abut spaanse the respective ends of the adapter to orient the wings relative thereto. The apertures i4 in the wing elements are aligned with the apertures 17 in the adapter thereby. Pins 18 projected through aligned apertures 14 and i7 iiX the wings to the adapter and relative the body 1. The shape of the passage 15 as derived from that of the slot 6 causes the inner or root portions or" the wings to curve in cross section to provide them with an advantageous airfoil configuration. With the wing elements so connected, their trailing edges deline lines generally perpendicular to the body 1 while their leading edges are swept back from their inner to their outer ends. As shown in the drawings, streamers 19 connect to the outer ends of the wing elements.

rhe kite thus provided is fabricated of sections of a foamed material which are relatively thin, lending a certain degree of resilience and liexibility thereto. Strings are connected fore and aft of the body 1 to provide a dependent bridle and a tow string is connected thereto. The kite may be readily launched by merely moving it through the air while gradually letting out the tow string and pulling at it at appropriate intervals.` Pulling on the string applies a drag on the body 1 causing the Wings to naturally flex upwardly. On partial release of the tow string, the wings will react by flexing oppositely, lifting the kite thereby. The inherent resilience and flexibility of the kite components enable the kite to be quickly and easily launched. These properties of the kite are so advantageous that it may be readily lifted and iiown where the existing wind velocity is as littlek as three miles per hour. Moreover, once the kite is in the air, the saine properties cause the wings to automatically flex to stabilize its position under the inliuence of existing air cur rents. This is particularly important where the wind velocity is high.

Thus, the invention provides a kite having highly improved liight characteristics through a wide range of conditions. Also, the fabrication thereof from a cellular material such as described provides it with a buoyancy that enhances its lift capabilities.

FIGS. 5 7 of the drawings show a preferred embodiment of the invention. Here we have a body l which is similar to the body 1 in outline but the slot 6 therein is rectangular, rather than flatly arcuate. Also, the body 1 has vertically aligned apertures 20 through its upper and lower portions delining the slot 6', respectively to either end thereof. Y

The

wings

2 and 3 are similar in conguration to the

wing elements

2 and 3 and similarly oriented with respect to the body 1'. However, in this case the mating ends 16 and i1 of the wings are dciined by straight edges forming lines generally perpendicular to their trailing edges.

An adapter 4"'is employed which consists of a pair of plates Z1 longer than the slots 6. Plates 21 are notched at 16', centrally of either end, so as to seat in body 1 within the slot and accommodate the portions of the body defining the ends of the slot. The plates 2l are thereby fixed to project laterally of the body 1 in relatively superposed relation to accommodate the mating ends of the wing elements 2 and 3' therebetween. The shoulders 9' to either side of the relatively projected ends of the wing elements abut the body 1 to either end of the slot t5'. The wings are thereby oriented to project generally perpendicular to the body 1.

Pins' Z2. projected through the vertically aligned aper- -tures Ztl in body 1' tix the plates 21 in clamping relation to the mated ends of the wings elements conlined therebetween.

The laterally projected edges of plates 21 are convergeht from front to rear while their extremities conform to the configuration of the leading and trailing edges ot the wings Z' and 3'. Aligned apertures 23 are provided in the plates 21 and wings 2' and 3' located at respective corners of the plates, as may be seen with reference to the drawings.

String elements fore and aft of the Wing elements have their ends looped through aligned apertures 23 to either side of body 1', to further connect the Wings to plates 2,1 and form dependent loop portions Z4 of a bridle. The loop portions 24 are centrally connected under the body l by a string portion 2S to which the tow line 26 is attached at the fore part of the wings. The tow string is thus connected with a dependen-t bridle which is wider at its forward portion than its rear portion. Streamers 19 may be connected to the wings as shown.

This provides a preferred embodiment of the invention which functions similarly to the vtirst described embodiment. Like characteristics thereof need not be repeated. However, in this instance the simplicity of the components and their assembly should be particularly noted. Also, here the bridle affords a particularly balanced connection of the tow string to the kite as well as serving a connecting function with respect to the wing elements. The launching and iiight details here are similar to those described previously and should now be clearly obvious.

It will be seen that the kite as provided by the invention is uniquely fabricated of a cellular substance and in a form rendering it highly eliicient in use. The configuration illustrated is not only appealing lto the eye but enhances kite stability. Streamers are shown but these are optional.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is suscep tible of modification in its form, proportions, detail con` struction and arrangement of parts without departing from thel principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into eiect, and the invention is therefore claimed in any of its forms or rnodications within the legitimate and valid scope of the appended claims.
