Abstract: A steel pole for a rectangular dome-shaped tent is disclosed wherein a plurality of unit rods 1 are made of an elastic steel pipe with a certain thickness. One end portion of each of the unit rods is press-formed into an insert part 1a for being inserted into an insert hollow 1b of another unit rod 1, the insert part having a proper length and a proper diameter. The unit rods consist of straight rods 1A and bent rods 1B, the bent rod 1B being bent at a certain angle to support a corner portion between the tent ceiling and the tent wall. Each steel pole consists of a plurality of the unit rods 1 in the form of a straight rod 1A or a bent rod 1B, and the rods 1 are arranged in a number and in an order suitable to pitch a dome-shaped tent. A flexible and elastic string s passes through the unit rods thus arranged for forming an arched pole. Two arched poles A and B are installed on the ground, the top portion of the arched poles crossing each other for pitching a rectangular dome-shaped tent 2.

Abstract: A tower type sunshade is disclosed, in which a conical roof tent can be formed in a simple manner without using any minor beams. The tower type sunshade according to the present invention includes four posts 1 and four lateral rods 2 respectively connected through four f-shaped connectors 3 to the four posts. Four major beams 4 are connected to the upper tips of the f shaped connectors 3 and to an X shaped connector 3a in the diagonal directions to form an X shaped contour. A tubular supporting rod 5 of a certain length is connected vertically to the upper tip of the X shaped connector 3a, and a roof tent cloth 6 having a peak part 6a is installed thereon, the peak part 6a being fitted to the upper tip of the tubular supporting rod 5. A securing rod 7 having a flange 7a is installed, the lower tip of the securing rod 7 being fitted into the upper tip portion of the tubular supporting rod 5.
