发明名称 Folding patio chair
摘要 An improved folding chair structure having a pair of parallel frame tubes and a pair of parallel support tubes that are laterally foldable, each pair held in respective parallel relationships by front and rear x-braces, and also included is a pair of parallel seat tubes the rear end of which being pivotally attached to a fixed intermediate point along an associated support tube, the structure further including a separate guide movably mounted along intermediate portions of each of the frame tubes, the guides being pivotally attached to the upper ends of associated brace members of both the front and rear x-braces and also to an associated one of the seat tubes whereby the collapsing of the structure by moving the parallel frame, support and seat tubes together causes the guides to move upwardly while the angle between the planes defined by the respective frame and support tubes and between the planes defined by the respective support and seat tubes, decreases.
