It contains a pillar. The rhombus chain system includes two pairs of scissors-shaped chain rings that pivot about each other at the inner end. The outer ends of the two chain rings, respectively forming two pairs of scissors-shaped chain rings, are pivoted about a fixed joint mounted on the upper end of each column and a movable joint movable along the column. Each stationary seam is provided with a multisegmented rib extending about it and extending therefrom so that it can be pivotally joined by a central connector. The elongated chain loop extends so that it can pivot about each of the movable joints and therefrom pivotally connected to the appropriate position along each rib. By means of the members, the tent forms a square or rectangular frame formed by upright pillars, the rhombic chain loop system is connected between the pillars, and the cross-shaped superstructure is connected to the central connector. It is formed by the ribs and elongated chain loops that unfold and support the ribs.

However, the conventional tent support requires a locking device to fix the tent in an expanded or open state and to prevent the tent from being neglected or unintentionally collapsed. In addition, the rhombic chain loop system, which is formed at both ends in the shape of scissors, occupies a large space that can be utilized in the tent, and in particular, a space at a position between two scissors shapes that are pivoted with respect to each other. . This limits the space used by the tent.

Therefore, it is desirable to have an improved tent structure of this kind that can reduce the space occupied by the support and keep the tent firm in the unfolded state.
