Patent ID: 8096619

Claim:
A foldable leisure chair comprising: a seat unit including a pair of side frames that are spaced apart from each other in a left-right direction; a backrest unit connected to said side frames of said seat unit; a pair of armrest members spaced apart from each other in the left-right direction, a left one of said armrest members being connected to a left one of said side frames and being pivotable relative to said left one of said side frames about an axis that is parallel to the left-right direction, a right one of said armrest members being connected to a right one of said side frames and being pivotable relative to said right one of said side frames about the axis, each of said armrest members having a pivot segment that is connected pivotally to a corresponding one of said side frames, and a coupling segment that extends from a front end of said pivot segment; and a pair of support units, each of which includes an elongated coupling seat that has a seat body defining a receiving space therein, and having a pivot end part that is connected pivotally to a respective one of said side frames and an open end part that is opposite to said pivot end part in a longitudinal direction transverse to the axis and that is formed with an opening in spatial communication with said receiving space, an elongated seat-engaging rod that has an engaging end part extending telescopically into said receiving space of said coupling seat through said opening, and a connecting end part opposite to said engaging end part in the longitudinal direction and connected pivotally to said coupling segment of a corresponding one of said armrest members, said coupling seat of each of said supporting units being pivoted away from the respective one of said side frames, and said seat-engaging rod of a corresponding one of said support units being moved away from said pivot end part of said coupling seat of the corresponding one of said support units in the longitudinal direction when a corresponding one of said armrest members is pivoted away from a corresponding one of said side frames, said coupling seat of each of said supporting units being pivoted toward the corresponding one of said side frames, and said seat-engaging rod of the corresponding one of said support units being moved toward said pivot end part of said coupling seat of the corresponding one of said support units in the longitudinal direction when the corresponding one of said armrest members is pivoted toward the corresponding one of said side frames, and an adjusting mechanism that is disposed in said receiving space of said coupling seat for positioning said seat-engaging rod relative to said coupling seat so as to maintain the corresponding one of said armrest members at a selected one of a plurality of angular positions relative to the corresponding one of said side frames.
