Balloon Adapter

Ballon-Aufsatz — the balloon adapter that mounts on top of the upper housing. The balloon is attached to the adapter and during game air is pumped through the adapter into the ballon. The ballon then inflates until it hits the spike in the roof.

Bounding box: ≈ ⌀32 × 25 mm (round flange diameter × height).

Interior

A section down the centreline shows the through-bore: the wide seat at the top where the balloon sits, the barb ridges that grip it, and the counterbored inlet under the flange. The second section adds the hose nozzle in its assembled position, so the full air path is visible — from the balloon seat, down the adapter bore, through the nozzle elbow, and out to the barbed tubing fitting.

Side cut — through the bore, barbs, and mounting flange

Adapter + nozzle — the continuous bore through both parts
