Abstract

A lift assembly for use during inflation of a balloon envelope is provided. The lift assembly includes a plate structure that has a set of cavities. Each cavity includes one or more openings passing through the plate. One or more pistons are coupled to the plate through at least one of the openings of each cavity in the set of cavities. Each piston has a hollow tube portion projecting lengthwise from the at least one opening, a flange attached to the hollow tube portion and a grabber portion in communication with the flange. The grabber portion includes a plurality of bearings for grabbing a stud attached to an apex of the balloon envelope. A handle portion is coupled to the plate. The handle is arranged to lift the balloon envelope when the bearings have grabbed a given stud.

First claim

The invention claimed is:

1. A system for lifting an inflatable envelope, the system comprising:
a plate structure having an opening passing through the plate structure; and
an actuating member attached to the plate structure through the opening, the actuating member having a body portion projecting from the opening, a projection attached to a tube portion and an attachment portion in communication with the projection, the attachment portion being configured for releasable attachment to a portion of the envelope and to allow the plate structure and actuating member to lift the envelope.

2. The system of claim 1 , wherein the attachment portion is configured for attachment to a stud attached to the envelope.

3. The system of claim 1 , further comprising an airflow unit coupled to the actuating member, the airflow unit being configured to actuate the actuating member in order attach the attachment portion to the balloon envelope.

4. The system of claim 1 , wherein the actuating member includes a cap at one end of the actuating member, the cap being configured to hold the actuating member within the opening.

5. The system of claim 1 , wherein the plate structure and actuating member are arranged to facilitate lifting of the envelope while the envelope is being inflated.

6. The system of claim 1 , wherein the attachment portion includes a plurality of ball bearings configured to grab the portion of the balloon envelope.

7. The system of claim 6 , wherein the actuating member is configured to, when actuated to a first position, extend out into the attachment portion in order to open the plurality of bearings wide enough to attach the attachment portion to the portion of the envelope.

8. The system of claim 7 , wherein the actuating member is configured to, when actuated to a second position, clamp the plurality of bearings around the portion of the envelope.

9. The system of claim 6 , wherein the plurality of ball bearings are arranged as a wreath.

10. The system of claim 1 , wherein the tube portion is a hollow tube portion and the projection is configured to pass through the hollow tube portion when the actuating member is actuated.

11. The system of claim 10 , wherein the hollow tube portion is configured to be filled with air in order to actuate the actuating member.

12. The system of claim 1 , further comprising the envelope.

13. The system of claim 1 , further comprising a hoist device arranged with the plate structure and actuating member in order to lift the envelope high enough to accommodate a fully inflated balloon envelope.

14. The system of claim 1 , wherein the plate structure is formed from two or more plates joined to one another such that the opening extends through each of the two or more plates.

15. The system of claim 1 , wherein the actuating member includes a piston arranged at least partially in the opening.

16. The system of claim 1 , wherein the opening and the actuating member have complementary shapes.

17. The system of claim 16 , wherein the complementary shapes allow the actuating member to rotate within the opening.

18. The system of claim 1 , further comprising a handle attached to the plate structure.

19. The system of claim 1 , wherein the plate structure includes an integrated handle.

20. The system of claim 1 , further comprising at least three additional actuating members.
