Each spoke consists of four abutting units; three at one end are pressed onto the connecting sleeve into which fits the end of the other link. Going tent simple and fast: lay the folded ladder, lattermann in one direction, the awning is collected and prodelyvat in laderman spokes, the ends are inserted into the sleeves of rolling locks, then the locks pull cord slightly to each other so as to form spokes from the arc. Is only pulling extreme arc over you a slice for a slice unfold the whole dome. Tent developed by V. Seregin from Kazan, was successfully tested PA Taimyr and in other campaigns.
