4 Claims.

The present invention deals with toy kite construction, and has for its general object the provision of a kite possessing improved and novel flight characteristics.

It is an additional object of the present invention to provide a toy kite which embodies the principle of jet propulsion through the use of a tunnel-like member having an enlarged intake opening and a restricted discharge orifice, which member is attached to a relatively flat airfoil surface to afford propulsion thereto as air passes through the member during flight.

It is a further object of this invention to provide a toy kite of this character which is structurally simple and economical in manufacture.

For a further and more complete understanding of the present invention, reference is made to the following description and appended drawing wherein:

Fig. 1 is a perspective view of a kite formed in accordance with the present invention;

Fig. 2 is a top plan view thereof;

Fig. 3 is a longitudinal vertical sectional view taken along the line 3-3 of Fig. 2;

Fig. 4 is a transverse vertical sectional View taken along the-line 4-4 of Fig. 3;

Fig. 5 is a bottom plan view of a slightly modifled form of kite embodying the features of the present invention.

Referring now to the drawing, the kite disclosed therein makes use of a longitudinal member ID, and a transverse member ll joined substantially at its center with the first-mentioned member Ill, by a staple l2, to form a cross-shaped supporting frame. Each of the frame members Ill and H are preferably formed from strips of a lightweight wood of the type generally used in kite construction.

The respective ends of the frame members are slotted in the usual manner to receive a perimetrically extending string l3, which, when maintained in a substantially taut condition, provides a form member for the body of the kite.

The kite body or covering it is formed from any suitable material such as paper or lightweight closely woven cloth, and is cut to conform to the shape outlined by the string [3. In cutting the body 14, a substantial oversize edge I5 is left, which edge is overlapped upon the string l3 and adhesively secured to the outer portions of the body. It will be noted, that the body [4 constitutes the underside of the kite, and the frame members rest thereon.

A relatively large opening I6 is formed in the position around the juncture of the two frame members In and I I. Over this opening, and upon the upper surface of the body I4, is secured a tapered dome-shaped member H. The latter is also formed from paper or the like, and is adhesively united at its outer edges with the upper surface of the body and with the respective frame members Ill and H so as to form a substantially air-tight seal therewith. The rearward tapered end of the dome member I1 is provided with a restricted opening 18. Referring particularly to Fig. 4 of the drawings, it will be noted that the member ll for-ms a substantially tapered tunnel with the body of the kite, to which tunnel communicates the large opening l6 and the restricted opening I8. I

It will be seen that air entering the tunnel through the opening [6 at a given velocity will pass backwardly of the tapered tunnel where its volume is restricted and be discharged from the restricted" opening H3 at a substantially greater velocity. Such discharge at increased velocities will tend to give the kite a forward thrust.

As shown in Fig. l, a flying string is attached to the kite at the juncture of the frame members and extends below the bottom surface thereof. When wind is received upon the under side of the body, the kite will tend to fly by its ordinary airfoil characteristics, common to all kites of this general configuration. In addition to this, :a mass of air will pass through the tunnel member I! and out of the restricted opening [8 at the rear end of the kite at increased velocity, thus causing the kite to be boosted forward. It will be apparent that if the kite is in an inclined position, the same will climb at a relatively fast rate as long as air is striking the under side of the body at a given velocity. If the flying string is utilized to hold the kite against the wind, the kite will climb until it reaches a substantially horizontal plane above the ground. The flying action of the kite is characterized by its fast ascension to a substantially horizontal plane at which time a distinct wabbling action ensues due to the fiat configuration of its under side which tends to spill the air as it passes by in a horizontal direction. Also the pull characteristics of the kite upon the flying string is greatly increased over the ordinary kite, which characteristics are deemed desirable by children, as it gives the impression of a large and fast flying kite.

Fig. 5 of the drawings discloses a slightly modified form of kite embodying the features of the present invention, wherein the rearward tapered body of the kite and is disposed in an encircling end of the tunnel I1 is closed, and a restricted 3 opening [9 formed toward the rear end of the kite in the kite body I4.

It will be manifest that practically the same flying action will be present in this modified form as in the primar form previously described, that is, the thrust action produced by air passing through the tunnel and out of the restricted opening I 9 at increased velocity. However, the climbing action of this kite differs somewhat from the primary form, in that the climbing fiight is characterized by a zig-zag course from side to side until it reaches a substantially horizontal plane.

In view of the foregoing, it will be seen that the present invention contemplates a highly novel toy kite whose flight characteristics are distinct and unique as compared to the kites now in -ordinary use. Through the medium of jet propulsion, the speed of the kite in its ascension is great- 1y increased.

While the drawing and specification disclose what is now deemed to be preferred forms of the present invention, it will be manifest that various modifications are possible within the scope of the following claims.

1. A toy kite comprising a frame, a covering for said frame, said covering being formed toward its forward portion with a relatively enlarged air-intake opening, and an elongated longitudinally and transversely tapered envelope carried longitudinally of said covering and forming therewith an elongated longitudinally tapered passageway, said passageway communicating at one end with the air-intake opening formed in said covering and being provided at its opposite end with a relatively restricted air-discharge opening.

2. A toy kite Comprising a frame, a covering for said frame providing a substantially flat air foil body, said covering being formed toward the forward end thereof with an enlarged air-intake opening, and an enclosed envelope carried upon oneside of said covering in longitudinally extending order thereon said envelope forming with said covering an elongated longitudinally and transversely tapered passageway communicating at one end with the air-intake opening formed in said covering, said passageway being provided at its opposite end with a relatively restricted discharge opening for the passage of air introduced within said passageway by way of said intake opening.

3. A toy kite comprising a frame including a longitudinal member, a transverse member, and a string joining the respective ends of said members, a covering for said frame providing a substantially fiat air foil body, said covering being formed with a relatively enlarged air intake opening at the juncture of the longitudinal and transverse mem-bers of said frame, and a dome-shaped envelope carried on one side of said covering and extending longitudinally thereof, said envelope forming with said covering an elongated longitudinally and transversely tapered passageway, said passageway communicating at the forward end thereof with the air intake opening of said covering and terminating at the rearward end thereof in a relatively restricted discharge opening.

4. A toy kite comprising :a frame, a, coverin for said frame providing a substantially flat air foil body, a rounded longitudinally and transversely tapered envelope attached to said covering on one side thereof and extending substantially the length of said covering, said envelope forming with said covering a longitudinally extending and tapered air passage, said air passage being provided toward its forward end with a relatively large intake opening and at its opposite end with a relatively restricted discharge openmg.
