Abstract

A balloon apparatus is provided having (1) a cage structure that includes (a) a plurality of vertical tendons, where each of the vertical tendons includes a first end and second end, where the first ends of the vertical tendons are all connected to one another and where the second ends of the vertical tendons are all connected to one another and (b) one or more horizontal tendons, where each horizontal tendon is attached to each of the vertical tendons at a corresponding level of the cage structure and (2) a balloon envelope, where the balloon envelop is arranged inside the cage structure and inflatable within the cage structure.

First claim

What is claimed is:

1. A balloon apparatus comprising:
a cage structure comprising:
(a) a plurality of vertical tendons, wherein each of the vertical tendons comprises a fiber cable with a first end and a second end, wherein the first ends of the vertical tendons are all connected to one another and wherein the second ends of the vertical tendons are all connected to one another, and wherein each vertical tendon comprises an opening at each level corresponding to a horizontal tendon; and
(b) one or more horizontal tendons, wherein each horizontal tendon comprises a fiber cable that is attached to each of the vertical tendons at a corresponding level of the cage structure by passing through the opening of each vertical tendon at the corresponding level; and

a balloon envelope, wherein the balloon envelope is arranged inside the cage structure and inflatable within the cage structure.

2. The balloon apparatus of claim 1 , further comprising a top plate and a bottom plate, wherein the first ends of the vertical tendons are all connected to one another using the top plate and the second ends of the vertical tendons are all connected to one another using the bottom plate.

3. The balloon apparatus of claim 1 , wherein the balloon envelop is not rigidly attached to the cage structure.

4. The balloon apparatus of claim 1 , comprising three horizontal tendons.

5. The balloon apparatus of claim 4 , wherein the three horizontal tendons comprise:
a first horizontal tendon attached to each of the vertical tendons at a midpoint of each of the vertical tendons;
a second horizontal tendon attached to each of the vertical tendons halfway between the midpoint and a bottom end of each of the vertical tendons; and
a third horizontal tendon attached to each of the vertical tendons halfway between the midpoint and a top end of each of the vertical tendons.

6. The balloon apparatus of claim 1 , wherein the horizontal tendons correspond to levels at equally spaced points on the vertical tendons.

7. The balloon apparatus of claim 1 , wherein the horizontal tendons correspond to levels that are not equally spaced on the vertical tendons such that more horizontal tendons are attached at points in top halves of the vertical tendons.

8. A balloon apparatus comprising:
a cage structure comprising:
(a) a plurality of vertical tendons, wherein each of the vertical tendons comprises a fiber cable with a first end and a second end, wherein the first ends of the vertical tendons are all connected to one another and wherein the second ends of the vertical tendons are all connected to one another, and wherein each vertical tendon comprises an opening at each level corresponding to a horizontal tendon; and
(b) one or more horizontal tendons, wherein each horizontal tendon comprises a fiber cable that is attached to each of the vertical tendons at a corresponding level of the cage structure by passing through the opening of each vertical tendon at the corresponding level; and

wherein the connected vertical and horizontal tendons surround a space fillable by a balloon envelope when the balloon envelope is inflated.

9. The balloon apparatus of claim 8 , further comprising a top plate and a bottom plate, wherein the first ends of the vertical tendons are all connected to one another using the top plate and the second ends of the vertical tendons are all connected to one another using the bottom plate.

10. A method comprising:
connecting a first end of each of a plurality of vertical tendons to one another, wherein each vertical tendon comprises a fiber cable, and wherein each vertical tendon comprises an opening at each level corresponding to a horizontal tendon;
connecting a second end of each of the vertical tendons to one another;
attaching one or more horizontal tendons to each of the vertical tendons, wherein each horizontal tendon comprises a fiber cable that is attached to each of the vertical tendons at a corresponding height of the vertical tendons by passing each horizontal tendon through the opening of each vertical tendon at the corresponding level; and
inflating a balloon envelope inside the connected vertical and horizontal tendons.

11. The method of claim 10 , wherein:
connecting the first end of each of the vertical tendons to one another comprises connecting the first end of each of the vertical tendons to a top plate; and
connecting the second end of each of the vertical tendons to one another comprises connecting the second end of each of the vertical tendons to a bottom plate.

12. The method of claim 10 , wherein:
attaching the one or more horizontal tendons to each of the vertical tendons occurs during a first time period;
inflating the balloon envelope inside the connected vertical and horizontal tendons occurs during a second time period; and
the second time period begins at a time after the first time period ends.
