Filed Oct. 24, 1961, Ser. No. 147,245 3 Claims. (Cl. 244-31) This invention relates to balloon construction and more particularly to a fin assembly adapted for use on balloons of the kite or captive type, and to means by which such a fin assembly can be readily secured to or detached from the balloon envelope.

The advantages and uses of captive or kite balloons are well known, the same being used for many purposes, such as for the sending aloft of photographic cameras, various kinds of instruments for weather determination or for other uses, for advertising etc.

Under certain weather conditions it is desirable to secure proper stabilization of the balloon by the use of tail fins, and it is therefore an object of the invention to provide a fin assembly for use on these balloons and to provide means by which such an assembly can be easily applied to or removed from the envelope of the balloon.

it is another object of the invention to provide a finsupporting frame structure having its elements so connected as to permit of collapse or dis-assembly, thereby requiring the structure to need but small space during transportation or storage.

It is an object of the invention to provide a novel means for attaching a fin assembly to the gas bag or envelope whereby the fin structure can be unitarily removed from the bag or attached to the same.

More particularly, the invention contemplates the pro- Vision of a plurality of light weight metal frames encircling the balloon envelope adjacent to its rear end and maintained in spaced relation thereon, said frames being connected and maintained in their spaced relation by radially-projecting fins, such fins including as part of their frames, rods having ends which project forwardly and rearwardly of the assembly frames and which ends are removably received in socket members in the form of flexible loops or straps provided on the outer surface of the bag or envelope.

With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed,

FIG. 1 is a side elevational view of a captive or kite balloon to which the improved tail or fin assembly has been applied;

FIG. 2 is an end view of the balloon as seen from the right of FIG. 1;

FIG. 3 is a perspective view of the tin assembly;

FIG. 4 is an enlarged sectional view, taken substantially on the line t-4 of FIG. 2, looking in the direction of the arrows;

FIG. 5 shows the connection employed between struts or parts of the fin assembly, and

HQ. 6 shows how the extended parts of the fins are inserted in sockets in the form of loops or straps provided on the envelope of the balloon.

Referring to the drawing, 1 generally indicates the bag or gas envelope of the balloon. The body of the envelope is composed of fabric of any kind that can be suitably employed for balloon construction and the envelope is of the non-rigid type or that in which its shape is maintained by being gas-inflated. In the form shown, the bag or envelope is of tear-drop shape, having a larger-diameter forward nose portion 2 and a tapering rear end or tail portion 3.

The fin assembly, adapted for attachment to the tapering rear end 2 of the envelope, is adapted to be secured to the envelope by elements entering into a plurality of sockets in the form of loops or straps 4 and 4a secured on the outer surface of the envelope at suitable positions thereon in the tapering tail area thereof. These loops 4- and in may be composed of flexible tapes or the like.

The fin assembly includes a pair of substantially rectangular frames indicated respectively at 5 and 6, said frames being disposed in spaced relation on the envelope by means of the four fins indicated respectively at 7, 8, 9 and 1d. The several fins may be of the shape illustrated or they may be of other shape according to stabilizing requirements.

Each of the fins consists of a fabric-covered frame, preferably composed of light weight metal rod, such as aluminum, and each frame includes an outer rod 11, an inner or base rod 12. and end rods 13 and 14. Each of the inner rods 12 is extended or projected beyond the frames 5 and 6, the extended end 15 of such rods constituting elements which fit under the loops or straps 4 and 4a to thereby removably attach the fin assembly to the envelope.

The fins 7 to 14} inclusive have their covering provided with reinforced apertures as shown at 16 and 17, the apertures 16 enabling the ends of the rods which form the frame 6 to have access to and pivotally attach to brace member 18 which form a part of each of the frames of the fins. Bolts such as shown at 19 are used to establish connection between the elements of the frame 6 and the braces 18.

The forward or larger frame 5 of the assembly is braced adjacent to its corners by means of diagonal braces 20 which connect to the inner rod 12 of the fin frames. The rods which form the frame 5 are attached by bolts 22 (FIG. 4) to the forward struts 13 of the fin frames. The rear or smaller frame 6 of the assembly is braced by the brace members shown at 23.

All of the framework of the fin assembly can be made of light weight metal, such as aluminum rod, and the joinder between the various parts of the several frames may be established by bolts, such as shown at 18 in FIG. 5 and through such arrangement the frames may be quickly and easily collapsed and dis-mantled for trans portation, storage or for other purposes.

In its assembled position, the fin assembly appears as shown in FIG. 3, and in fitting the same upon the tapered rear end of the balloon, it is placed on the envelope thereof with the larger frame 5 arranged foremost and the smaller frame 6 disposed adjacent to the rear extremity of the envelope. The tapered rear end of the envelope fits within the braces Zti of the forward frame 5 and fits within and is encircled by the braces 23 of the rear frame 6. In attaching the fin assembly to the balloon envelope, the forwardly projecting ends 15 of the rods 12 are inserted under the forward loops or straps do, While the rearWardly-projecting ends l5 are inserted under the rear loops or straps 4, thus securely attaching the fin assembly to the balloon envelope but permitting its ready detachment therefrom by withdrawing the ends 15 from under the several loops or straps 4 and do, when weather conditions do not require the use of stabilizing fins on the balloon.

When the fin assembly is removed from the envelope, the connections between the various struts and brace members are such as to permit collapse of the several frames and if desired, the quick dis-mantling of the assembly.

By means of the construction described, a fin assembly is provided which can be readily attached to or removed from a balloon envelope without the employment of parts or elements likely to damage the fabric of the envelope; which fin assembly can be quickly attached to or removed from the envelope Without requiring the use of tools, and which assembly can be collapsed or dis-assembled to enable it to occupy only a small space during transportation or storage.

While I have herein suggested that the envelope of the balloon shall be of certain conformation and that the described assembly shall include four fins, it will be apparent that the envelope may be of a shape other than that illustrated and the number of fins employed may be increased or decreased. For example, a three-finned assembly can also be made and used with complete satisfaction.

The nature of the fin assembly is such that if a balloon envelope is damaged or destroyed, the fin assembly is likely to remain intact or only slightly damaged, and if damaged the damaged parts are easily replaced and the assembly speedily made ready for attachment to another balloon envelope.

Having thus described a single embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming Within the scope of the annexed claims.

What I claim is:

l. A fin assembly for balloons comprising, a pair of spaced-apart rectangular metal-rod frames, said frames being maintained in their spaced relation by means of a plurality of radially-projecting fins, each fin consisting of a fabric-covered metal rod frame including an inner 30 frame element, each of said frame elements having projecting ends extending beyond the frames, and a balloon envelope provided on its outer surface with a plurality of loop members into Which said projecting ends are inserted to extend longitudinally of the balloon thereby attaching the assembly to the balloon envelope.

2. A fin assembly as provided for in claim 1, wherein the frames and fins are "connected in operative relationship by means permitting their .vpivotal collapse, and the loops on the envelope arrangedin spaced relation on the outer face of the balloon envelope to removably receive the end elements on the fin frame members.

3. A fin assembly for a balloon envelope having a tapered rear end, a fin-rnou'nting assembly including a forward frame encircling the envelope in advance of the rear extremity of the envelope, a smaller frame encircling the envelope substantially'close to its rear extremity, brace means in each of the frames for strengthening the same, the envelope fitting within the brace means, a plurality of fins extending between the frames and maintaining them in their spaced relation, each of said fins having a base rod formed with extended ends projecting beyond the frames and forming attaching elements, the envelope having a plurality of loops on its outer face for the reception of the attaching elements to thereby secure the fin assembly to the balloon envelope.
