RGS's daily vort today posted a link to an article by Eretz Chemdah which
described a design for an umbrella that could be opened on Shabbos. The
design change is simple: There is a "Magein haShabbas" on the umbrella's
shaft above the main dome that is a tefach wide and cannot close. So
that opening the umbrella is enlarging an ohel arai, not creating one.
Here's my question: Don't people put umbrellas down? So, this magein is
often less than a tefach off the floor, or sideways while the umbrella
is being put down and the top is rotated to the bottom.
Wouldn't you have to also keep the umbrella upright?
