Airborne, free-floating untethered hovering balloons, sometimes also referred to as Mylar balloons, initially were primarily considered as toys for children. However, they also became of interest to and as amusements for hobbyists. These balloons are made to float or hover in mid-air not tethered by strings or the like, by attaching ballast to the balloon's envelope, see my U.S. Pat. Nos. 4,307,537 and 4,547,167, for example. In general, the user selectively attaches or removes weight-balancing tabs or ballast tabs until the weight of the balloon envelope and the ballast equals the lift of the helium gas contained in the balloon envelope causing the balloon to achieve “neutral buoyancy” so that it hovers in mid-air at a desired height.
Over the years a relatively small number of balloon sizes and shapes became standard. But the increased popularity as a child's toy and as a hobbyist activity has led to the desire for and production of a greater number of different and intricate balloon shapes and sizes. Examples may be, a multiple-pointed star shaped decorated balloon or a replica of a human or an animal which the user may want to make hover at different altitudes and attitudes from time to time. But this has led to a more difficult and somewhat more complicated and arduous scheme or procedure for achieving and maintaining neutral buoyancy and desirable attitude for the balloon. This apparently has adversely affected growth in popularity of the hovering balloon by both children and hobbyist. To offset this I have found that the weight balancing or ballast system must address the many different shapes and sizes of these balloons, which are currently available and those which may evolve in the future. Some shapes require significantly more ballast than others to hover at the desired height or altitude because of their inherent weight and some lose their altitude and/or attitude and list, either initially or if they lose helium over time.
In addition, because of the shapes some balloon can only accommodate long narrow shaped ballast while others might require wider shorter shaped ballast to maintain attitude in flight.
Therefore, the correct size, weight and location of the ballast for each balloon may be significantly different.
In addition, since the ballast is adhesively backed for releasable attachment, because of the wide variety of shapes each balloon may have a different smooth surface available for attaching the ballast. This may affect the size or shape of the ballast that can be attached to the balloon envelope, e.g. a rectangular shape rather than square or circular one may be preferred or necessary.
Furthermore, advances in balloon manufacturing technology has led to the development of a multitude of balloons of different sizes and shapes, many decorated with unique artwork. Also, many present day hovering toy balloons are significantly larger than in the past and so may require heavier and/or larger ballast weight. In addition, some configured balloons may require precisely located weight tabs to retain their proper orientation or attitude and hovering level.
Further, weight tabs or ballast tabs made out of opaque material attached to a balloon may detract from the decorative effect of the artwork on uniquely decorated balloons.
With hovering balloons becoming of greater interest to hobbyists and becoming more complex as designs of shapes and configurations and decorations has become more sophisticated and varied, the art has become more complicated. Therefore, the main object of the instant invention is to provide improvements in the field of hovering balloons, to overcome the problems introduced by the advent of the complexities mentioned above and still retain its basic operation and enjoyment.
As described hereinabove, the intricate and varied sizes and shapes of many hovering balloons may require fairly precise locations and weight of the ballast to keep it afloat at the desired altitude and attitude. In order to make it easier for the user to adjust the weight balance a feature of my invention is a sheet of ballast material, sometimes referred to as a ballast module, having a suitable adhesive coating on one surface and having embedded score lines which divide the sheet into a multiplicity of individual and equally-sized tabs, generally referred to as weight tabs or ballast tabs. Each tab is attached to its adjacent tab at the score line by at least one tab tie so that it is removable or detachable from its adjacent tab. This permits the ballast tabs to be removed from the module individually or in strips or blocks and be adhesively attached to the balloon as required for various shapes and sizes of balloons.
As an added feature, the ballast is made of a transparent material so that when attached to a balloon it does not detract from any decoration. Naturally the material must have sufficient weight to serve as adequate ballast.
A further feature of the invention is providing guidelines or markings on the outer skin of the balloon as to where it is preferable to place the ballast to ensure that the balloon will achieve neutral buoyancy so that it will float or hover at the desired altitude and attitude.
In accordance with the teachings of the instant invention of providing a ballast module and material as described along with suitable guide lines on the balloons, it is a further feature of the invention to provide instructions where necessary for applying the ballast onto uniquely shaped or configured balloons to avoid the “hit- and-miss” efforts of the past and thereby make the hovering amusement balloon more popular with children and hobbyists.
Referring now specifically to the drawings, in which identical or similar parts are designated by the same reference numerals throughout, a detailed description of the present invention is given. It should be understood that the following detailed description relates to the best presently known embodiment of the invention. However, the present invention can assume numerous other embodiments, as will become apparent to those skilled in the art.
In specific regards to ballast module 11, a ballast module 11 generally comprises a sheet of weight bearing material, preferably about 8 to 20 mils in thickness, preferably weighing 4 to 10 grams, preferably a transparent material and more preferably a transparent plastic material, and most preferably a tear resistant transparent plastic material, having intersecting score lines defining a multiplicity of individual ballast tabs 14. Ballast module 11 also includes an adhesive layer 15 located on one surface of the ballast module 11 for removably attaching the tab(s) to the amusement balloon 12, usually, but not always after it is inflated.

Referring to
Typically, for example, tab placement guide markings 28 may provide the user with general instructions on where on amusement balloon 27 to attach ballast tabs 29 to achieve proper balance and also general instructions on the number or amount of ballast tabs 29 to attach to amusement balloon 27 to enable amusement balloon 27 to free-float, hover and untethered. This can be very helpful for users where the altitude can be quite different at different locations depending on sea level.
For example, referring to
To combat the undesirable list or tilting effect of the amusement balloon 40 due to an uneven distribution of weight resulting from the presence of tail portion 42,
