Claim. (Cl. 244—153)

The present invention relates to a kite construction.

Although not limited thereto, the present invention will be particularly described in its application to a kite construction, and particularly in its application to a thin plastic kite construction which may be flown and have bird like qualities.

A further object is to provide a novel flexible kite construction which may be readily assembled of lightweight materials and which when flown, may be caused to simulate the action of a bird in flight.

Still further objects and advantages v/ill appear in the \ mere detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and &gt; not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects, it has been found most satisfactory according to one embodiment of the present invention to provide a kite construction consisting of a cross like frame for a central vertical main spine member v/ith relatively movable outstanding side members which are attached to the spine member by means of a sloppy or laminated movement fit.

The plastic body of the kite itself may simulate the outline of a bird, and the ends of the wings may extend to the ends of the cross member.

The upper end of the spine member should preferably be positioned at the end of the head, and the lov/er end of the spine should be positioned at the lower end of the tail.

Desirably, the ends of the arms and the ends of the cross member are connected together by a peripheral extending, cord which fits into slots or otherwise permanently connected to the ends of the vertical member and cross members.

The plastic body of the kite itself is not attached to the skeleton or cross structure directly, but is attached to the peripheral cord or strings by means of heat sealing.

Desirably, the peripheral cords are coated with a plastic material which enables them to be heat sealed to the body of the kite, or they are stapled or eyeleted to the body of the kite.

It is a particular feature of the present invention that the body of the kite is attached to the peripheral cords while the cords are attached to the skeleton so that there is no direct connection between the body of the kite it_h self and the skeleton.

In respect to the pull cord, the pull cord is joined by two triangular arrangements, one of which is attached ' to the strings which form the upper edges of the strings,

I and the other of which is attached to the upper and lower ends of the vertical spine member.

These two triangular arrangements are joined together by a short cord, and this short cord in turn is joined to the flying or main earner cord for the kite.

By this construction, it is possible to obtain an unusually strong yet flexible kite construction with freedom of wing and body movements which closely approximates the action of a flying bird and with pulling or release of the suspension or pull cord giving an unusual flying effect.

V/ith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically

16, or notches or staples may be provided to hold it in position.

The inside ends 17 of the arms 14 fit in the sockets 18 formed by the tube 15, and since their diameters are smaller than the sockets 18, they have a sloppy fit which permits a certain amount of free movement both in the directions 19 as indicated in FIG. 4 as well as in the directions transverse thereto.

This loose fit as indicated in FIG. 4 permits a flapping motion of the wings in view of the limited freedom of movement of the side spar or cross members, both in the direction 19, and in the direction transverse to the direction 19.

The upper and lower ends 20 and 21 and the outside ends 23 will carry the continuous peripheral cord D by eyelets or by a slotted connection as is indicated for example in FIG. 2α.

As shown in FIG. 2α, the end slot 23 will receive the portion 24 of the cord D which extends peripherally around the outside of the kite structure, and which is tightly engaged so that it will also limit the freedom of movement of the cross members 14.

The peripheral cord system D will join the body A of the kite to the cross skeleton structure B.

Desirably, the body 25 of the cord as shown in FIG. 2b has an impregnation or coating of a plastic material of the same nature as the plastic body A of the kite, and this may be heat sealed to the edge portions 27 of the body of the kite by heat at the crossing areas as for example are indicated at 28 in the tail section, 29 at the lower portions of the wings, and 30 at the upper portion of the head.

The upper edges of the wings as indicated at 31 may be sealed in the same manner as indicated in FIG. 2b, but they preferably may be held in position by means of the eyelets 32 which are heat sealed at 33 to the edge 31 of the wing structure.

If desired, the upper edge of the wing structure might be wrapped around the cords, and heat sealed thereto to give a suitable connection.

It is thus apparent that the construction of the kite as shown in FIGS. 1 and 2 involves connecting the skeleton B to the peripheral cord D which then is heat sealed or otherwise connected by eyelets to the crossing portions of the peripheral cord D at 28, 29, 3:3 and 31.

This connection permits greater flexibility and lightness of the kite and enables the operation thereof to simulate a flying bird without the heaviness of the support skeleton greatly constricting the flapping movement.

In connection with the suspension cord or the leading cord system, the triangular system F has a junction at 45 where the upper cord 46 joins the lower cord 47.

The ends 48 and 49 of these cords are stapled or otherwise permanently fastened to the upper and lower ends 26 and 21 of the central cross member 13.

This triangular cord system F includes the cords 46 and 47 and will act as a base structure for the suspension cord system, and it is connected by the short run or extension H to the outer junction 50.

The outer junction 50 joins together the two cord members 51 which connect the cross cord members along the upper edges 31 of the wings 10 at the junction points 52.

These junction points 52 may be formed by heat sealing, by staples or by tying the cords together.

The junction point 5® is connected directly to the string or cord E which goes down to the earth and is held by the user of the kite.

These two triangular systems F formed of the cords 46 and 47 and G formed of the cords 51 give the flying movement to the wings 10 of the body A.

When the cord E is pulled down by the user of the kite, the pressure at the junction point 59 will cause the wings 10 to come together and be lowered from their normal horizontal position.

This will create a reverse bias or strain in the cord structure 46 and 47 forming part of the inside triangular system F.

Therefore, when the suspension or holding string is momentarily released, the wings 1® will tend to fly back in their upper position or more horizontal position, and this alternating pull and release on the string E will cause a very attractive and unusual flying movement of the kite.

A pull or substantial jerk on the string E will tend to cause the wings 1® to flap together downwardly tensioning the inside system 46 and 47 through the short cord H and the junction 45, and the release will permit the wings to flap up.

The side elements 14 as well as the vertical or main spine 13 of the cross element B will usually have such flexibility or pliability so as to permit slight movement thereof and a reverse restoration movement under the action of the main cord E and the triangular systems F and G.

In the alternative junction structure indicated at D in FIG. 5, the main spine member 7® is provided with a cross bar or rod 71 which fits in the recesses 72 on the inside end 73 of the side arms.

This socket connection of the cross bar or rod 71 in the socket 72 will permit the limited flapping motion characteristic cf the junction structure C.

In the embodiment of FIGS. 6 and 7, the junction structure E has a vertical member SO which is clamped between the fiat spring coils 81 at the junction point.

These flat spring coils are tied by the loops 82 and by the integral connections S3 to the coil members 84 which serve as sockets to receive the ends 85 of the cross members.

Each coil 84 will have a separated spiral structure 84, and also will have two flat coils 81 joined thereto by the inside members 86.

This junction structure shown in E permits the same limited movement of the cross bars 85 in respect to the main spine member 80 as is true in the junctions of FIGS. 4 and 5.

It is apparent that the applicant has provided a simple kite structure which is readily flown of inexpensive manufacture, and permits a flapping movement.

The junction of the polyethylene film A together with the coated or impregnated cords 25 will give a permanent junction between ths peripheral cord system D and the body A cf the kite, which structure then may be mounted on the ends of the cruciform skeleton B.

Normally, in flying the kite, the wind will hold the kite up and flat, and a jerk or pull on the cord E v/ill cause the wings to flap together with subsequent release, restoring the wings to their flat condition.

Instead of sealing the peripheral cord system in the manner indicated in FIGS. 1 and 2, it is also possible to use strips of polyethylene material to seal the cords D down to and against the body of the kite.

As many changes could be made in the above kite construction, and many widely different embodiments of this invention could be made without departing from the scope of the claim, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
