Abstract

An inflation device adapted to admit compressed gas to the interior of a balloon, and to seal that interior against the atmosphere after inflation, is comprised of a pair of circular disks in parallel alignment and spaced from each other. The disks are rigidly affixed to a central shank which extends beyond one of them. The shank extension is bored with a passage, sealed at the far end thereof, in communication with the annular space between the disks by means of a radial orifice. The tubular neck of the balloon is stretched over the sealing disks, with the shank extension protruding from the opening of the balloon sheath. Upon pressurizing the passage in the shank with air, or other inflating medium, that portion of the balloon stretched between the two disks distends and permits the inflating medium to enter the internal volume of the gasbag around the periphery of the inner disk. The inflation device may be adapted to the inflation of multiple nested balloons by the addition of further sealing disks along the extended shank.

Claims

1. As an article of commerce, the combination of an inflatable balloon, an inflation device provided with a cylindrical inflation channel coaxial with the inflated balloon when installed in the inflating nozzle integral with said balloon, an elongated rigid manipulating rod, frictionally engaged in said inflation channel, and a support member, wherein said support member comprises:

a support ring for said balloon;

anchor means adapted to frictionally engage a portion of said manipulating rod; and

rib means interconnecting said anchor means with said support ring.

2. As an article of commerce, the combination of an inflatable balloon, an inflation device provided with a cylindrical inflation channel coaxial with the inflated balloon when installed in the inflating nozzle integral with said balloon, an elongated rigid manipulating rod, frictionally engaged in said inflation channel, and a support member, wherein said support member comprises;

a support ring for said balloon;

anchor means adapted to frictionally engage a portion of said inflation device; and

rib means interconnecting said anchor means with said support ring.

3. A one-piece inflation device, comprising:

an elongated, tubular shank with a cylindrical bore open to one end thereof and closed at the other end;

three circular, planar sealing disks, rigidly affixed to said tubular shank and projecting therefrom at right angles in a parallel spaced array, with an innermost of said sealing disks proximate to said other end of the tubular shank, constructed with diametral dimensions progressively increasing along said array, away from said innermost sealing disk; and

orifice means diametrally piercing said tubular shank between at least one pair of sealing disks in said array wherein said oriface means pierces said tubular shank to communicate with each of the two annular spaces formed between each pair of said three sealing disks.

4. The device of claim 3, additionally comprising reinforcing means, including a plurality of radially extending ribs integral with said tubular shank between at least one pair of sealing disks in said array.
