The present invention relates to a leisure chair that is rotated up and folded according to contraction.

  7 to 10 are structural views showing a conventional leisure chair. The structure is a folded structure in which two crossing plates 90 having the same length are crossed in an X shape. The handrail rod structure 80 is an intermediate folding structure including a male joint 81, a female joint 82, and a handrail rod 83, but this structure has the following drawbacks.

  As one of the drawbacks, the handrail rod structure 80 employs an intermediate folding structure, and the handrail rod structure 80 is a portion that supports the weight of the arm. The middle part of the intermediate folding structure is very weak because it is a folding part. If it is bent many times, it will gradually loosen, and one day, the structure may break when the arm is placed. Furthermore, since the joints of the male joint 81 and the female joint 82 are easy to pinch fingers and arms, there is a problem in safety in use.

As a second drawback, as shown in FIG. 10, the seat sheet 100 and the bone frame connection method are four-point connection of a four-legged rod, and there is no support at the central portion. Since the contact area of this point articulation method is small, there is a possibility that the seat seat 100 and the bone frame articulation contact may be broken if used for a long time.
