Abstract: An elongated post includes a sleeve and an extension, the extension slidably retained within the sleeve. A handle is disposed at a free end of the extension. The sleeve has a first end near the handle and a second end opposite the first end. A pair of cylinder rests is provided, one each of the rests positioned on each of two opposite sides of the sleeve at the second end of the sleeve. The cylinder rests are foldable against the sleeve. A pair of cylinder straps is disposed on each side of the sleeve. Each pair of cylinder straps is adapted for holding a cylinder to the post, such that a distal end of the cylinder rests against one of the cylinder rests. The cylinder straps are foldable against the sleeve. A pair of shoulder straps is attached to the post for wearing the post on a human back. A pair of wheels is disposed at the second end of the sleeve. The post is inscribed with indicia indicating an empty cylinder near the first end of the sleeve, and indicia indicating a filled cylinder near the second end of the sleeve. A person can place the cylinder within the cylinder with a neck of the cylinder disposed near the first end or the second end of the sleeve, to indicate whether the cylinder is empty or filled.

Abstract translation: 细长柱包括套筒和延伸部，该延伸部可滑动地保持在套筒内。 手柄设置在延伸部的自由端。 套筒具有靠近手柄的第一端和与第一端相对的第二端。 提供一对圆筒支架，其中每个支架位于套筒第二端处的套筒的两个相对侧的每一个上。 圆筒支架可以相对于套筒折叠。 一对气缸带设置在套筒的每一侧。 每对气缸带适于将气缸保持在柱上，使得气缸的远端靠在气缸座中的一个上。 气缸带可以相对于套筒折叠。 一个肩带上贴有一个肩背，用于穿在人背上。 一对轮子设置在套筒的第二端。 该柱被刻有指示在套筒的第一端附近的空的圆柱体的标记，以及指示在套筒的第二端附近的填充的圆筒的标记。 人们可以将气缸放置在气缸内，其中颈部设置在套筒的第一端或第二端附近，以指示气缸是空的还是填充的。
