PURPOSE:To set and remove frames simply and rapidly by the operation of a rope by inserting the rope furnished with bar bodies to be fitted in joint parts through a folding frame connecting several gate-shaped frames in parallel to support a tent. CONSTITUTION:A tent 28 is stretched on several gate-shaped wheeled frames 30 in parallel, and these gate-shaped frames 30 are mutually connected by a folding connection frame 36 via joint parts 40. Through this connection frame 36, a rope 48 is inserted, and on this rope 48, frame-stiffening bar bodies to be fitted in joint parts 40 of the connection frame 36 are fixed to be moved in one body with the rope 48. Folding frames 40 are extended, and after parallel gate-shaped frames 30 are set on the opening of a hatch, the rope 48 is pulled in one direction. This construction permits to fit bar bodies in joint parts 40, ensure the setting of gate-shaped frames 30, fix and remove them rapidly and simply.
