Abstract
The rigid helium balloon has a helium compartment and a separate, channel portion. Helium gas is filled into the helium compartment through a valve in the balloon. Fiberglass rod members are inserted into the channel portion to help retain the desired shape of the balloon. The rod members also provide a counterbalancing weight which prevents the balloon from floating upward. Thus, the balloon, once released into the air, will retain its shape and remain floating at the height from which it was released unless repositioned. No additional weights or tethering devices are required to prevent the balloon from floating upwards.
Claims6
A rigid helium balloon comprising:
- a first skin portion;
- a second skin portion joined to said first skin at a double seam about their periphery, the double seam defining a channel extending about the periphery of the first and second skin portions;
- a helium compartment disposed between said first and second portions;
- at least one rod member disposed within said channel portion, said rod member having opposing ends;
- and
- at least one connector secured to at least one of said opposing rod ends to hold said rod member in said channel portion.
A rigid helium balloon comprising:
- a first skin member;
- a second skin member joined to said first skin member at a first peripheral seam and at a second peripheral seam, said second peripheral seam being spaced from said first peripheral seam;
- a helium compartment disposed between said first and second skin members;
- a channel portion defined between said first peripheral seam and said second peripheral seam, said channel portion having at least two rod apertures;
- at least one fiberglass rod member disposed within said channel portion, said rod member having opposing ends;
- and
- a connector secured to at least one of said opposing rod ends;
- wherein said first and second skin portions are made from polyethylene terephthalate.
