730. Campers in Three Adjacent Enclosures

Shabbos 16:14

Let’s say that three areas are enclosed for purposes other to serve as dwellings, are located next to one another, and open to one another. Furthermore, the two outside enclosures are wide and the one in the middle is narrow. There are barriers on either side around the outside areas. If three people make Shabbos, one in each of the three areas, they are considered a caravan and they may carry wherever their needs may require. If the middle area is wide and the two outside areas are narrow, there are barriers on either side of the middle area with the result that it is considered separate from the outer areas. Therefore, if three people make Shabbos, one in each of these three areas, they do not have carte blanche to carry throughout the enclosure. Rather, each person is limited to carrying within his own area, and even that requires that it be smaller than needed to plant two seah. If one person makes Shabbos in each of the outside areas, while two people make Shabbos in the middle area (total: four people), or two people make Shabbos in each of the outer areas with one person in the middle area (five people), they may carry wherever their needs require.

If a partition cannot stand up to an ordinary wind, it is considered insignificant. If a partition was not built to endure, it is considered insignificant. A partition that was set up solely for privacy is considered insignificant. A partition lower than ten handbreadths (about 30”) is considered incomplete. If a mound five handbreadths tall (about 15”) has a partition of five handbreadths on it, they combine to form a valid partition of ten handbreadths.
