STACKABLE WEIGHTS FOR LIGHTER-THAN-AIR BALLOONS |
摘要 |
An adjustable weight for tethering lighter-than-air balloons that may include a plurality of individual weights secured together by a friction fit. The weights each have a top wall and a side wall extending from a periphery of the top wall. The side wall includes a top tier adjacent to the top wall and a base tier extending from the top tier. The base tier is larger in size than the top tier to facilitate nesting of adjacent weights, and a step is formed at the intersection of the top tier and the base tier. An attachment member extends from the weight and provides a tethering point for lighter-than-air balloons.
